+grub2 (1.96+20090609-1) experimental; urgency=low
+
+  Before this version, grub-efi was 32bit on i386 and 64bit on amd64.
+  However, EFI can be 32bit even if you have a 64bit CPU, like in the
+  first MacBook models with Core 2 Duo released in late 2006.  Thus,
+  grub-efi has been split into grub-efi-amd64 and grub-efi-ia32 which are
+  available on both amd64 and i386.
+  
+  If you've experienced problems trying to load grub.efi, please try
+  again using the package that doesn't match your CPU's architecture.

+Git Tree
+========
+
+The grub2 packaging is maintained via the grub-team project on Salsa:
+https://salsa.debian.org/grub-team
+
+The primary git tree is grub-team/grub.  It can be obtained with:
+
+     git clone https://salsa.debian.org/grub-team/grub
+
+Git Subtrees
+------------
+
+grub.git/debian/grub-extras is maintained using git subtree merges.  To
+update it to a given commit, first ensure that you have the relevant
+upstream remote, e.g.:
+
+    git remote add -f grub-extras https://git.sv.gnu.org/git/grub-extras.git
+
+And then:
+
+    git subtree merge -P debian/grub-extras <commit>
+
+Git Branches
+------------
+
+grub-team/grub uses git-dpm and contains the following branches:
+
+- upstream:
+
+  The master branch of the upstream grub.git tree, at the point
+  corresponding to the current Debian package version.
+
+- master:
+
+  The main packaging branch, based on upstream.  debian/patches
+  maintained using git-dpm.
+
+- pristine-tar:
+
+  pritine-tar metadata based on upstream (not upstream).

+
+MAKE SURE YOU ARE RUNNING THE LATEST VERSION
+
+The grub packages never update the installed version of GRUB
+automatically, except if you choose a device in the debconf prompt
+`GRUB install devices', which is currently only implemented for grub-pc.
+
+Because of this, you need to make sure you're running the LATEST VERSION of
+GRUB before you report a bug.  Use grub-install to update it, and then check
+if the bug still applies.  Debugging problems we already fixed makes us waste
+valuable time, so please try to avoid it.
+
+IMPORTANT NOTE WHEN SUBMITTING PATCHES
+
+Like many other FSF projects, GRUB upstream has specific requirements for
+accepting patches with regard to copyright assignment.  If you're going to
+submit a patch, it is likely that it will only be accepted in upstream if you're
+willing to submit your paperwork as well.
+
+Because of this, we want to avoid diverging from upstream by adding patches to
+the Debian package unless we know the copyright issues can be sorted out.  We
+encourage you to submit your work to upstream directly by sending a mail to the
+GRUB maintainers <grub-devel@gnu.org>.

+      with EFI handover patches, avoiding ExitBootServices.
+    - Temporarily make linuxefi refuse to validate kernels in the absence of
+      a shim, until we get some other details worked out.
+    - Automatically call linuxefi from linux if secure boot is enabled and
+      the kernel is signed, to hand over to the kernel without calling
+      ExitBootServices.  Otherwise, linux will fall through to previous
+      code, call ExitBootServices itself, and boot the kernel normally.

+      grub-reboot/grub-set-default movement in Ubuntu.
+  * Don't do a separate build pass for grub-common.  It will be identical to

+    reuse that.
+  * Build with GCC 4.5 on all architectures.
+  * Update Lintian overrides for changes in Lintian 2.5.0~rc1.
+  * Invert how files are split among binary packages: rather than code in
+    debian/rules to remove files we don't want, add dh_install configuration
+    to declare the files we do want.  This means a little more repetition
+    for platform-specific programs, but it seems less confusing and easier
+    to extend.
+  * Drop versioned dependencies on base-files.  GPL-3 has been there for two
+    Debian releases now, and the dependency was never upgrade-critical
+    anyway.
+  * Create grub2-common package containing files that are common among GRUB

+  * Drop redundant Suggests: os-prober from several platform packages, as
+    grub-common already Recommends: os-prober.
+  * Create grub-<platform>-bin packages corresponding to all grub-<platform>
+    packages (except for grub-emu).  These do not automatically install the
+    boot loader or update grub.cfg, and they install their binaries to
+    /usr/lib/grub/<cpu>-<platform>/; this means that they can be installed
+    in parallel, making it easier to use them to build GRUB-based disk
+    images (e.g. d-i).  The grub-<platform> packages now depend on these and
+    include symlinks, so their behaviour will remain as before.
+  * Make grub-emu depend on grub-common.
+  * Make the documentation directory in most binary packages be a symlink to
+    that in grub-common.
+  * Drop lenny compatibility from grub2-common's dpkg/install-info

+    - Support submenus.
+    - Write embedding zone using Reed-Solomon, so that it's robust against

+ License
+ .
+ THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+ COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+ COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+ AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+ .
+ BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO
+ BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY BE
+ CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS CONTAINED
+ HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND CONDITIONS.
+ .
+ 1. Definitions
+    "Adaptation" means a work based upon the Work, or upon the Work and
+    other pre-existing works, such as a translation, adaptation, derivative
+    work, arrangement of music or other alterations of a literary or
+    artistic work, or phonogram or performance and includes cinematographic
+    adaptations or any other form in which the Work may be recast,
+    transformed, or adapted including in any form recognizably derived from
+    the original, except that a work that constitutes a Collection will not
+    be considered an Adaptation for the purpose of this License. For the
+    avoidance of doubt, where the Work is a musical work, performance or
+    phonogram, the synchronization of the Work in timed-relation with a
+    moving image ("synching") will be considered an Adaptation for the
+    purpose of this License.
+    "Collection" means a collection of literary or artistic works, such as
+    encyclopedias and anthologies, or performances, phonograms or
+    broadcasts, or other works or subject matter other than works listed in
+    Section 1(f) below, which, by reason of the selection and arrangement of
+    their contents, constitute intellectual creations, in which the Work is
+    included in its entirety in unmodified form along with one or more other
+    contributions, each constituting separate and independent works in
+    themselves, which together are assembled into a collective whole. A work
+    that constitutes a Collection will not be considered an Adaptation (as
+    defined below) for the purposes of this License.
+    "Creative Commons Compatible License" means a license that is listed at
+    http://creativecommons.org/compatiblelicenses that has been approved by
+    Creative Commons as being essentially equivalent to this License,
+    including, at a minimum, because that license: (i) contains terms that
+    have the same purpose, meaning and effect as the License Elements of
+    this License; and, (ii) explicitly permits the relicensing of
+    adaptations of works made available under that license under this
+    License or a Creative Commons jurisdiction license with the same License
+    Elements as this License.
+    "Distribute" means to make available to the public the original and
+    copies of the Work or Adaptation, as appropriate, through sale or other
+    transfer of ownership.
+    "License Elements" means the following high-level license attributes as
+    selected by Licensor and indicated in the title of this License:
+    Attribution, ShareAlike.
+    "Licensor" means the individual, individuals, entity or entities that
+    offer(s) the Work under the terms of this License.
+    "Original Author" means, in the case of a literary or artistic work, the
+    individual, individuals, entity or entities who created the Work or if
+    no individual or entity can be identified, the publisher; and in
+    addition (i) in the case of a performance the actors, singers,
+    musicians, dancers, and other persons who act, sing, deliver, declaim,
+    play in, interpret or otherwise perform literary or artistic works or
+    expressions of folklore; (ii) in the case of a phonogram the producer
+    being the person or legal entity who first fixes the sounds of a
+    performance or other sounds; and, (iii) in the case of broadcasts, the
+    organization that transmits the broadcast.
+    "Work" means the literary and/or artistic work offered under the terms
+    of this License including without limitation any production in the
+    literary, scientific and artistic domain, whatever may be the mode or
+    form of its expression including digital form, such as a book, pamphlet
+    and other writing; a lecture, address, sermon or other work of the same
+    nature; a dramatic or dramatico-musical work; a choreographic work or
+    entertainment in dumb show; a musical composition with or without words;
+    a cinematographic work to which are assimilated works expressed by a
+    process analogous to cinematography; a work of drawing, painting,
+    architecture, sculpture, engraving or lithography; a photographic work
+    to which are assimilated works expressed by a process analogous to
+    photography; a work of applied art; an illustration, map, plan, sketch
+    or three-dimensional work relative to geography, topography,
+    architecture or science; a performance; a broadcast; a phonogram; a
+    compilation of data to the extent it is protected as a copyrightable
+    work; or a work performed by a variety or circus performer to the extent
+    it is not otherwise considered a literary or artistic work.
+    "You" means an individual or entity exercising rights under this License
+    who has not previously violated the terms of this License with respect
+    to the Work, or who has received express permission from the Licensor to
+    exercise rights under this License despite a previous violation.
+    "Publicly Perform" means to perform public recitations of the Work and
+    to communicate to the public those public recitations, by any means or
+    process, including by wire or wireless means or public digital
+    performances; to make available to the public Works in such a way that
+    members of the public may access these Works from a place and at a place
+    individually chosen by them; to perform the Work to the public by any
+    means or process and the communication to the public of the performances
+    of the Work, including by public digital performance; to broadcast and
+    rebroadcast the Work by any means including signs, sounds or images.
+    "Reproduce" means to make copies of the Work by any means including
+    without limitation by sound or visual recordings and the right of
+    fixation and reproducing fixations of the Work, including storage of a
+    protected performance or phonogram in digital form or other electronic
+    medium.
+ .
+ 2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+ limit, or restrict any uses free from copyright or rights arising from
+ limitations or exceptions that are provided for in connection with the
+ copyright protection under copyright law or other applicable laws.
+ .
+ 3. License Grant. Subject to the terms and conditions of this License,
+ Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+ perpetual (for the duration of the applicable copyright) license to
+ exercise the rights in the Work as stated below:
+ .
+    to Reproduce the Work, to incorporate the Work into one or more
+    Collections, and to Reproduce the Work as incorporated in the
+    Collections;
+    to create and Reproduce Adaptations provided that any such Adaptation,
+    including any translation in any medium, takes reasonable steps to
+    clearly label, demarcate or otherwise identify that changes were made to
+    the original Work. For example, a translation could be marked "The
+    original work was translated from English to Spanish," or a modification
+    could indicate "The original work has been modified.";
+    to Distribute and Publicly Perform the Work including as incorporated in
+    Collections; and,
+    to Distribute and Publicly Perform Adaptations.
+ .
+    For the avoidance of doubt:
+        Non-waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme cannot be waived, the Licensor reserves
+        the exclusive right to collect such royalties for any exercise by
+        You of the rights granted under this License;
+        Waivable Compulsory License Schemes. In those jurisdictions in which
+        the right to collect royalties through any statutory or compulsory
+        licensing scheme can be waived, the Licensor waives the exclusive
+        right to collect such royalties for any exercise by You of the
+        rights granted under this License; and,
+        Voluntary License Schemes. The Licensor waives the right to collect
+        royalties, whether individually or, in the event that the Licensor
+        is a member of a collecting society that administers voluntary
+        licensing schemes, via that society, from any exercise by You of the
+        rights granted under this License.
+ .
+ The above rights may be exercised in all media and formats whether now
+ known or hereafter devised. The above rights include the right to make such
+ modifications as are technically necessary to exercise the rights in other
+ media and formats. Subject to Section 8(f), all rights not expressly
+ granted by Licensor are hereby reserved.
+ .
+ 4. Restrictions. The license granted in Section 3 above is expressly made
+ subject to and limited by the following restrictions:
+ .
+    You may Distribute or Publicly Perform the Work only under the terms of
+    this License. You must include a copy of, or the Uniform Resource
+    Identifier (URI) for, this License with every copy of the Work You
+    Distribute or Publicly Perform. You may not offer or impose any terms on
+    the Work that restrict the terms of this License or the ability of the
+    recipient of the Work to exercise the rights granted to that recipient
+    under the terms of the License. You may not sublicense the Work. You
+    must keep intact all notices that refer to this License and to the
+    disclaimer of warranties with every copy of the Work You Distribute or
+    Publicly Perform. When You Distribute or Publicly Perform the Work, You
+    may not impose any effective technological measures on the Work that
+    restrict the ability of a recipient of the Work from You to exercise the
+    rights granted to that recipient under the terms of the License. This
+    Section 4(a) applies to the Work as incorporated in a Collection, but
+    this does not require the Collection apart from the Work itself to be
+    made subject to the terms of this License. If You create a Collection,
+    upon notice from any Licensor You must, to the extent practicable,
+    remove from the Collection any credit as required by Section 4(c), as
+    requested. If You create an Adaptation, upon notice from any Licensor
+    You must, to the extent practicable, remove from the Adaptation any
+    credit as required by Section 4(c), as requested.
+    You may Distribute or Publicly Perform an Adaptation only under the
+    terms of: (i) this License; (ii) a later version of this License with
+    the same License Elements as this License; (iii) a Creative Commons
+    jurisdiction license (either this or a later license version) that
+    contains the same License Elements as this License (e.g.,
+    Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible
+    License. If you license the Adaptation under one of the licenses
+    mentioned in (iv), you must comply with the terms of that license. If
+    you license the Adaptation under the terms of any of the licenses
+    mentioned in (i), (ii) or (iii) (the "Applicable License"), you must
+    comply with the terms of the Applicable License generally and the
+    following provisions: (I) You must include a copy of, or the URI for,
+    the Applicable License with every copy of each Adaptation You Distribute
+    or Publicly Perform; (II) You may not offer or impose any terms on the
+    Adaptation that restrict the terms of the Applicable License or the
+    ability of the recipient of the Adaptation to exercise the rights
+    granted to that recipient under the terms of the Applicable License;
+    (III) You must keep intact all notices that refer to the Applicable
+    License and to the disclaimer of warranties with every copy of the Work
+    as included in the Adaptation You Distribute or Publicly Perform; (IV)
+    when You Distribute or Publicly Perform the Adaptation, You may not
+    impose any effective technological measures on the Adaptation that
+    restrict the ability of a recipient of the Adaptation from You to
+    exercise the rights granted to that recipient under the terms of the
+    Applicable License. This Section 4(b) applies to the Adaptation as
+    incorporated in a Collection, but this does not require the Collection
+    apart from the Adaptation itself to be made subject to the terms of the
+    Applicable License.
+    If You Distribute, or Publicly Perform the Work or any Adaptations or
+    Collections, You must, unless a request has been made pursuant to
+    Section 4(a), keep intact all copyright notices for the Work and
+    provide, reasonable to the medium or means You are utilizing: (i) the
+    name of the Original Author (or pseudonym, if applicable) if supplied,
+    and/or if the Original Author and/or Licensor designate another party or
+    parties (e.g., a sponsor institute, publishing entity, journal) for
+    attribution ("Attribution Parties") in Licensor's copyright notice,
+    terms of service or by other reasonable means, the name of such party or
+    parties; (ii) the title of the Work if supplied; (iii) to the extent
+    reasonably practicable, the URI, if any, that Licensor specifies to be
+    associated with the Work, unless such URI does not refer to the
+    copyright notice or licensing information for the Work; and (iv) ,
+    consistent with Ssection 3(b), in the case of an Adaptation, a credit
+    identifying the use of the Work in the Adaptation (e.g., "French
+    translation of the Work by Original Author," or "Screenplay based on
+    original Work by Original Author"). The credit required by this Section
+    4(c) may be implemented in any reasonable manner; provided, however,
+    that in the case of a Adaptation or Collection, at a minimum such credit
+    will appear, if a credit for all contributing authors of the Adaptation
+    or Collection appears, then as part of these credits and in a manner at
+    least as prominent as the credits for the other contributing authors.
+    For the avoidance of doubt, You may only use the credit required by this
+    Section for the purpose of attribution in the manner set out above and,
+    by exercising Your rights under this License, You may not implicitly or
+    explicitly assert or imply any connection with, sponsorship or
+    endorsement by the Original Author, Licensor and/or Attribution Parties,
+    as appropriate, of You or Your use of the Work, without the separate,
+    express prior written permission of the Original Author, Licensor and/or
+    Attribution Parties.
+    Except as otherwise agreed in writing by the Licensor or as may be
+    otherwise permitted by applicable law, if You Reproduce, Distribute or
+    Publicly Perform the Work either by itself or as part of any Adaptations
+    or Collections, You must not distort, mutilate, modify or take other
+    derogatory action in relation to the Work which would be prejudicial to
+    the Original Author's honor or reputation. Licensor agrees that in those
+    jurisdictions (e.g. Japan), in which any exercise of the right granted
+    in Section 3(b) of this License (the right to make Adaptations) would be
+    deemed to be a distortion, mutilation, modification or other derogatory
+    action prejudicial to the Original Author's honor and reputation, the
+    Licensor will waive or not assert, as appropriate, this Section, to the
+    fullest extent permitted by the applicable national law, to enable You
+    to reasonably exercise Your right under Section 3(b) of this License
+    (right to make Adaptations) but not otherwise.
+ .
+ 5. Representations, Warranties and Disclaimer
+ .
+ UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+ OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+ KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+ INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+ FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT
+ OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER
+ OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF
+ IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+ .
+ 6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+ LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY
+ SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING
+ OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN
+ ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+ .
+ 7. Termination
+ .
+    This License and the rights granted hereunder will terminate
+    automatically upon any breach by You of the terms of this License.
+    Individuals or entities who have received Adaptations or Collections
+    from You under this License, however, will not have their licenses
+    terminated provided such individuals or entities remain in full
+    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+    survive any termination of this License.
+    Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the
+    Work under different license terms or to stop distributing the Work at
+    any time; provided, however that any such election will not serve to
+    withdraw this License (or any other license that has been, or is
+    required to be, granted under the terms of this License), and this
+    License will continue in full force and effect unless terminated as
+    stated above.
+ .
+ 8. Miscellaneous
+ .
+    Each time You Distribute or Publicly Perform the Work or a Collection,
+    the Licensor offers to the recipient a license to the Work on the same
+    terms and conditions as the license granted to You under this License.
+    Each time You Distribute or Publicly Perform an Adaptation, Licensor
+    offers to the recipient a license to the original Work on the same terms
+    and conditions as the license granted to You under this License.
+    If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this License, and without further action
+    by the parties to this agreement, such provision shall be reformed to
+    the minimum extent necessary to make such provision valid and
+    enforceable.
+    No term or provision of this License shall be deemed waived and no
+    breach consented to unless such waiver or consent shall be in writing
+    and signed by the party to be charged with such waiver or consent.
+    This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings,
+    agreements or representations with respect to the Work not specified
+    here. Licensor shall not be bound by any additional provisions that may
+    appear in any communication from You. This License may not be modified
+    without the mutual written agreement of the Licensor and You.
+    The rights granted under, and the subject matter referenced, in this
+    License were drafted utilizing the terminology of the Berne Convention
+    for the Protection of Literary and Artistic Works (as amended on
+    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and
+    the Universal Copyright Convention (as revised on July 24, 1971). These
+    rights and subject matter take effect in the relevant jurisdiction in
+    which the License terms are sought to be enforced according to the
+    corresponding provisions of the implementation of those treaty
+    provisions in the applicable national law. If the standard suite of
+    rights granted under applicable copyright law includes additional rights
+    not granted under this License, such additional rights are deemed to be
+    included in the License; this License is not intended to restrict the
+    license of any rights under applicable law.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+/** @file
+ *
+ * Error codes
+ *
+ * Return status codes as used within gPXE are designed to allow for
+ * maximum visibility into the source of an error even in an end-user
+ * build with no debugging.  They are constructed as follows:
+ *
+ * Bits 7-0 : PXE error code
+ *
+ * This is the closest equivalent PXE error code
+ * (e.g. PXENV_STATUS_OUT_OF_RESOURCES), and is the only part of the
+ * error that will be returned via the PXE API, since PXE has
+ * predefined error codes.
+ *
+ * Bits 12-8 : Per-file disambiguator
+ *
+ * When the same error number can be generated from multiple points
+ * within a file, this field can be used to identify the unique
+ * instance.
+ *
+ * Bits 23-13 : File identifier
+ *
+ * This is a unique identifier for the file generating the error
+ * (e.g. ERRFILE_tcp for tcp.c).
+ *
+ * Bits 30-24 : POSIX error code
+ *
+ * This is the closest equivalent POSIX error code (e.g. ENOMEM).
+ *
+ * Bit 31 : Reserved
+ *
+ * Errors are usually return as negative error numbers (e.g. -EINVAL);
+ * bit 31 is therefore unusable.
+ *
+ *
+ * The convention within the code is that errors are negative and
+ * expressed using the POSIX error code and (optionally) a per-file
+ * disambiguator, e.g.
+ *
+ *     return -EINVAL;
+ *
+ * or
+ *
+ *     #define ETCP_BAD_CHECKSUM EUNIQ_02
+ *     return -( EINVAL | ETCP_BAD_CHECKSUM )
+ *
+ * By various bits of preprocessor magic, the PXE error code and file
+ * identifier are already incorporated into the definition of the
+ * POSIX error code, which keeps the code relatively clean.
+ *
+ *
+ * Functions that wish to return failures should be declared as
+ * returning an integer @c rc "Return status code".  A return value of
+ * zero indicates success, a non-zero value indicates failure.  The
+ * return value can be passed directly to strerror() in order to
+ * generate a human-readable error message, e.g.
+ *
+ *     if ( ( rc = some_function ( ... ) ) != 0 ) {
+ *         DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
+ *         return rc;
+ *     }
+ *
+ * As illustrated in the above example, error returns should generally
+ * be directly propagated upward to the calling function.
+ *
+ */

+/* Get definitions for file identifiers */
+#include <gpxe/errfile.h>
+
+/* If we do not have a valid file identifier, generate a compiler

+/* Command style register access
+
+Registers CMD0, CMD2, CMD3,CMD7 and INTEN0 uses a write access technique called command style access. It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the  value bit that specifies the value that will be written into the selected bits of register. 
+
+eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered.

+ * are introduced: 3, 2, 1, 0.5 and 0.25 MBit/s.
+ *

+ * Modulation for Atheros' Turbo G and Turbo A, its supposed to provide a
+ * throughput transmission speed up to 40Mbit/s-60Mbit/s at a 108Mbit/s
+ * signaling rate achieved through the bonding of two 54Mbit/s 802.11g
+ * channels. To use this feature your Access Point must also suport it.
+ * There is also a distinction between "static" and "dynamic" turbo modes:
+ *
+ * - Static: is the dumb version: devices set to this mode stick to it until
+ *     the mode is turned off.
+ * - Dynamic: is the intelligent version, the network decides itself if it
+ *     is ok to use turbo. As soon as traffic is detected on adjacent channels
+ *     (which would get used in turbo mode), or when a non-turbo station joins
+ *     the network, turbo mode won't be used until the situation changes again.
+ *     Dynamic mode is achieved by Atheros' Adaptive Radio (AR) feature which
+ *     monitors the used radio band in order to decide whether turbo mode may
+ *     be used or not.
+ *
+ * This article claims Super G sticks to bonding of channels 5 and 6 for
+ * USA:
+ *
+ * http://www.pcworld.com/article/id,113428-page,1/article.html
+ *
+ * The channel bonding seems to be driver specific though. In addition to
+ * deciding what channels will be used, these "Turbo" modes are accomplished
+ * by also enabling the following features:
+ *
+ * - Bursting: allows multiple frames to be sent at once, rather than pausing
+ *     after each frame. Bursting is a standards-compliant feature that can be
+ *     used with any Access Point.
+ * - Fast frames: increases the amount of information that can be sent per
+ *     frame, also resulting in a reduction of transmission overhead. It is a
+ *     proprietary feature that needs to be supported by the Access Point.
+ * - Compression: data frames are compressed in real time using a Lempel Ziv
+ *     algorithm. This is done transparently. Once this feature is enabled,
+ *     compression and decompression takes place inside the chipset, without
+ *     putting additional load on the host CPU.

+ * enum ath5k_int - Hardware interrupt masks helpers
+ *
+ * @AR5K_INT_RX: mask to identify received frame interrupts, of type
+ * 	AR5K_ISR_RXOK or AR5K_ISR_RXERR
+ * @AR5K_INT_RXDESC: Request RX descriptor/Read RX descriptor (?)
+ * @AR5K_INT_RXNOFRM: No frame received (?)
+ * @AR5K_INT_RXEOL: received End Of List for VEOL (Virtual End Of List). The
+ * 	Queue Control Unit (QCU) signals an EOL interrupt only if a descriptor's
+ * 	LinkPtr is NULL. For more details, refer to:
+ * 	http://www.freepatentsonline.com/20030225739.html
+ * @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors).
+ * 	Note that Rx overrun is not always fatal, on some chips we can continue
+ * 	operation without reseting the card, that's why int_fatal is not
+ * 	common for all chips.
+ * @AR5K_INT_TX: mask to identify received frame interrupts, of type
+ * 	AR5K_ISR_TXOK or AR5K_ISR_TXERR
+ * @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?)
+ * @AR5K_INT_TXURN: received when we should increase the TX trigger threshold
+ * 	We currently do increments on interrupt by
+ * 	(AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2
+ * @AR5K_INT_MIB: Indicates the Management Information Base counters should be
+ * 	checked. We should do this with ath5k_hw_update_mib_counters() but
+ * 	it seems we should also then do some noise immunity work.
+ * @AR5K_INT_RXPHY: RX PHY Error
+ * @AR5K_INT_RXKCM: RX Key cache miss
+ * @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a
+ * 	beacon that must be handled in software. The alternative is if you
+ * 	have VEOL support, in that case you let the hardware deal with things.
+ * @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing
+ * 	beacons from the AP have associated with, we should probably try to
+ * 	reassociate. When in IBSS mode this might mean we have not received
+ * 	any beacons from any local stations. Note that every station in an
+ * 	IBSS schedules to send beacons at the Target Beacon Transmission Time
+ * 	(TBTT) with a random backoff.
+ * @AR5K_INT_BNR: Beacon Not Ready interrupt - ??
+ * @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now
+ * 	until properly handled
+ * @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA
+ * 	errors. These types of errors we can enable seem to be of type
+ * 	AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR.
+ * @AR5K_INT_GLOBAL: Used to clear and set the IER
+ * @AR5K_INT_NOCARD: signals the card has been removed
+ * @AR5K_INT_COMMON: common interrupts shared amogst MACs with the same
+ * 	bit value
+ *
+ * These are mapped to take advantage of some common bits
+ * between the MACs, to be able to set intr properties
+ * easier. Some of them are not used yet inside hw.c. Most map
+ * to the respective hw interrupt value as they are common amogst different
+ * MACs.

+ *
+ * @ah: the &struct ath5k_hw
+ * @mask: the bssid_mask, a u8 array of size ETH_ALEN
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ */
+/*
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:                0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (0001 & 1010) == 1010
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0010) == (0010)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+ * There are some special registers on the RF chip
+ * that control various operation settings related mostly to
+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the chip, using a special register,
+ * that holds all the settings we need. After we 've sent the
+ * data packet, we write on another special register to notify hw
+ * to apply the settings. This is done so that control registers
+ * can be dynamicaly programmed during operation and the settings
+ * are applied faster on the hw.
+ *
+ * We call each data packet an "RF Bank" and all the data we write
+ * (all RF Banks) "RF Buffer". This file holds initial RF Buffer
+ * data for the different RF chips, and various info to match RF
+ * Buffer offsets with specific RF registers so that we can access
+ * them. We tweak these settings on rfregs_init function.
+ *
+ * Also check out reg.h and U.S. Patent 6677779 B1 (about buffer
+ * registers and control registers):

+    This driver is written for the Digital Equipment Corporation series

+
+        DEPCA       (the original)
+    	DE100
+    	DE101
+	DE200 Turbo
+	DE201 Turbo
+	DE202 Turbo (TP BNC)
+	DE210
+	DE422       (EISA)
+
+    The  driver has been tested on DE100, DE200 and DE202 cards  in  a
+    relatively busy network. The DE422 has been tested a little.
+
+    This  driver will NOT work   for the DE203,  DE204  and DE205 series  of
+    cards,  since they have  a  new custom ASIC in   place of the AMD  LANCE
+    chip.  See the 'ewrk3.c'   driver in the  Linux  source tree for running
+    those cards.
+
+    I have benchmarked the driver with a  DE100 at 595kB/s to (542kB/s from)
+    a DECstation 5000/200.

+
+    The  driver was originally based  on   the 'lance.c' driver from  Donald
+    Becker   which  is included with  the  standard  driver distribution for
+    linux.  V0.4  is  a complete  re-write  with only  the kernel  interface
+    remaining from the original code.

+
+    Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
+    driver.
+
+    The original DEPCA  card requires that the  ethernet ROM address counter
+    be enabled to count and has an 8 bit NICSR.  The ROM counter enabling is
+    only  done when a  0x08 is read as the  first address octet (to minimise
+    the chances  of writing over some  other hardware's  I/O register).  The
+    NICSR accesses   have been changed  to  byte accesses  for all the cards
+    supported by this driver, since there is only one  useful bit in the MSB
+    (remote boot timeout) and it  is not used.  Also, there  is a maximum of
+    only 48kB network  RAM for this  card.  My thanks  to Torbjorn Lindh for
+    help debugging all this (and holding my feet to  the fire until I got it
+    right).
+
+    The DE200  series  boards have  on-board 64kB  RAM for  use  as a shared
+    memory network  buffer. Only the DE100  cards make use  of a  2kB buffer
+    mode which has not  been implemented in  this driver (only the 32kB  and
+    64kB modes are supported [16kB/48kB for the original DEPCA]).
+
+    At the most only 2 DEPCA cards can  be supported on  the ISA bus because
+    there is only provision  for two I/O base addresses  on each card (0x300
+    and 0x200). The I/O address is detected by searching for a byte sequence
+    in the Ethernet station address PROM at the expected I/O address for the
+    Ethernet  PROM.   The shared memory  base   address  is 'autoprobed'  by
+    looking  for the self  test PROM  and detecting the  card name.   When a
+    second  DEPCA is  detected,  information  is   placed in the   base_addr
+    variable of the  next device structure (which  is created if necessary),
+    thus  enabling ethif_probe  initialization  for the device.  More than 2
+    EISA cards can  be  supported, but  care will  be  needed assigning  the
+    shared memory to ensure that each slot has the  correct IRQ, I/O address
+    and shared memory address assigned.
+
+    ************************************************************************
+
+    NOTE: If you are using two  ISA DEPCAs, it is  important that you assign
+    the base memory addresses correctly.   The  driver autoprobes I/O  0x300
+    then 0x200.  The  base memory address for  the first device must be less
+    than that of the second so that the auto probe will correctly assign the
+    I/O and memory addresses on the same card.  I can't think of a way to do
+    this unambiguously at the moment, since there is nothing on the cards to
+    tie I/O and memory information together.
+
+    I am unable  to  test  2 cards   together for now,    so this  code   is
+    unchecked. All reports, good or bad, are welcome.
+
+    ************************************************************************
+
+    The board IRQ   setting must be  at an  unused IRQ which  is auto-probed
+    using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
+    {2,3,4,5,7}, whereas the  DE200 is at {5,9,10,11,15}.  Note that IRQ2 is
+    really IRQ9 in machines with 16 IRQ lines.
+
+    No 16MB memory  limitation should exist with this  driver as DMA is  not
+    used and the common memory area is in low memory on the network card (my
+    current system has 20MB and I've not had problems yet).
+
+    The ability to load this driver as a loadable module has been added. To
+    utilise this ability, you have to do <8 things:
+
+    0) have a copy of the loadable modules code installed on your system.
+    1) copy depca.c from the  /linux/drivers/net directory to your favourite
+    temporary directory.
+    2) if you wish, edit the  source code near  line 1530 to reflect the I/O
+    address and IRQ you're using (see also 5).
+    3) compile  depca.c, but include -DMODULE in  the command line to ensure
+    that the correct bits are compiled (see end of source code).
+    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+    kernel with the depca configuration turned off and reboot.
+    5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
+       [Alan Cox: Changed the code to allow command line irq/io assignments]
+       [Dave Davies: Changed the code to allow command line mem/name
+                                                                assignments]
+    6) run the net startup bits for your eth?? interface manually 
+    (usually /etc/rc.inet[12] at boot time). 
+    7) enjoy!
+
+    Note that autoprobing is not allowed in loadable modules - the system is
+    already up and running and you're messing with interrupts.
+
+    To unload a module, turn off the associated interface 
+    'ifconfig eth?? down' then 'rmmod depca'.
+
+    To assign a base memory address for the shared memory  when running as a
+    loadable module, see 5 above.  To include the adapter  name (if you have
+    no PROM  but know the card name)  also see 5  above. Note that this last
+    option  will not work  with kernel  built-in  depca's. 
+
+    The shared memory assignment for a loadable module  makes sense to avoid
+    the 'memory autoprobe' picking the wrong shared memory  (for the case of
+    2 depca's in a PC).
+
+    ************************************************************************
+    Support for MCA EtherWORKS cards added 11-3-98.
+    Verified to work with up to 2 DE212 cards in a system (although not
+      fully stress-tested).  
+
+    Currently known bugs/limitations:
+
+    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
+           not the command line for IRQ and memory address.  You can
+           specify them if you want, but it will throw your values out.
+           You still have to pass the IO address it was configured as
+           though.

+/**************************************************************************
+Etherboot -  BOOTP/TFTP Bootstrap Program
+Intel EEPRO/10 NIC driver for Etherboot
+Adapted from Linux eepro.c from kernel 2.2.17
+
+This board accepts a 32 pin EEPROM (29C256), however a test with a
+27C010 shows that this EPROM also works in the socket, but it's not clear
+how repeatably. The two top address pins appear to be held low, thus
+the bottom 32kB of the 27C010 is visible in the CPU's address space.
+To be sure you could put 4 copies of the code in the 27C010, then
+it doesn't matter whether the extra lines are held low or high, just
+hopefully not floating as CMOS chips don't like floating inputs.
+
+Be careful with seating the EPROM as the socket on my board actually
+has 34 pins, the top row of 2 are not used.

+/* Philosophy of this driver.
+ *
+ * Probing:
+ *
+ * Using the pci.c functions of the Etherboot code, the 82557 chip is detected.
+ * It is verified that the BIOS initialized everything properly and if
+ * something is missing it is done now.
+ *
+ *
+ * Initialization:
+ *
+ *
+ * The chip is then initialized to "know" its ethernet address, and to
+ * start recieving packets. The Linux driver has a whole transmit and
+ * recieve ring of buffers. This is neat if you need high performance:
+ * you can write the buffers asynchronously to the chip reading the
+ * buffers and transmitting them over the network.  Performance is NOT
+ * an issue here. We can boot a 400k kernel in about two
+ * seconds. (Theory: 0.4 seconds). Booting a system is going to take
+ * about half a minute anyway, so getting 10 times closer to the
+ * theoretical limit is going to make a difference of a few percent. */
+/* Not totally true: busy networks can cause packet drops due to RX
+ * buffer overflows. Fixed in V1.10 of this driver. [Kiszka] */
+/*
+ *
+ * Transmitting and recieving.
+ *
+ * We have only one transmit descriptor. It has two buffer descriptors:
+ * one for the header, and the other for the data.
+ * We have multiple receive buffers (currently: 4). The chip is told to
+ * receive packets and suspend itself once it ran on the last free buffer.
+ * The recieve (poll) routine simply looks at the current recieve buffer,
+ * picks the packet if any, and releases this buffer again (classic ring
+ * buffer concept). This helps to avoid packet drops on busy networks.
+ *
+ * Caveats:
+ *
+ * The Etherboot framework moves the code to the 48k segment from
+ * 0x94000 to 0xa0000. There is just a little room between the end of
+ * this driver and the 0xa0000 address. If you compile in too many
+ * features, this will overflow.
+ * The number under "hex" in the output of size that scrolls by while
+ * compiling should be less than 8000. Maybe even the stack is up there,
+ * so that you need even more headroom.
+ */

+/* The etherboot authors seem to dislike the argument ordering in
+ * outb macros that Linux uses. I disklike the confusion that this

+ * Etherfabric bitfield access
+ *
+ * Etherfabric NICs make extensive use of bitfields up to 128 bits
+ * wide.  Since there is no native 128-bit datatype on most systems,
+ * and since 64-bit datatypes are inefficient on 32-bit systems and
+ * vice versa, we wrap accesses in a way that uses the most efficient
+ * datatype.
+ *
+ * The NICs are PCI devices and therefore little-endian.  Since most
+ * of the quantities that we deal with are DMAed to/from host memory,
+ * we define our datatypes (efab_oword_t, efab_qword_t and
+ * efab_dword_t) to be little-endian.
+ *
+ * In the less common case of using PIO for individual register
+ * writes, we construct the little-endian datatype in host memory and
+ * then use non-swapping equivalents of writel/writeq, rather than
+ * constructing a native-endian datatype and relying on the implicit
+ * byte-swapping done by writel/writeq.  (We use a similar strategy
+ * for register reads.)

+/*
+  02 Jul 2007  Udayan Kumar	 1.2 ported the driver from etherboot to gPXE API.
+				     Fully rewritten,adapting the old driver.
+		      	      	     Added a circular buffer for transmit and receive.
+		                     transmit routine will not wait for transmission to finish.
+			             poll routine deals with it.
+  13 Dec 2003  Tim Legge         1.1 Enabled Multicast Support
+  29 May 2001  Marty Connor	 1.0 Initial Release. Tested with Netgear FA311 and FA312 boards

+  27 May 2006	mcb30@users.sourceforge.net (Michael Brown)
+     Rewrote to use the new net driver API, the updated PCI API, and
+     the generic three-wire serial device support for EEPROM access.
+
+  28 Dec 2002	ken_yap@users.sourceforge.net (Ken Yap)
+     Put in virt_to_bus calls to allow Etherboot relocation.
+
+  06 Apr 2001	ken_yap@users.sourceforge.net (Ken Yap)
+     Following email from Hyun-Joon Cha, added a disable routine, otherwise
+     NIC remains live and can crash the kernel later.
+
+  4 Feb 2000	espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
+     Shuffled things around, removed the leftovers from the 8129 support
+     that was in the Linux driver and added a bit more 8139 definitions.
+     Moved the 8K receive buffer to a fixed, available address outside the
+     0x98000-0x9ffff range.  This is a bit of a hack, but currently the only
+     way to make room for the Etherboot features that need substantial amounts
+     of code like the ANSI console support.  Currently the buffer is just below
+     0x10000, so this even conforms to the tagged boot image specification,
+     which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000.  My
+     interpretation of this "reserved" is that Etherboot may do whatever it
+     likes, as long as its environment is kept intact (like the BIOS
+     variables).  Hopefully fixed rtl_poll() once and for all.  The symptoms
+     were that if Etherboot was left at the boot menu for several minutes, the
+     first eth_poll failed.  Seems like I am the only person who does this.
+     First of all I fixed the debugging code and then set out for a long bug
+     hunting session.  It took me about a week full time work - poking around
+     various places in the driver, reading Don Becker's and Jeff Garzik's Linux
+     driver and even the FreeBSD driver (what a piece of crap!) - and
+     eventually spotted the nasty thing: the transmit routine was acknowledging
+     each and every interrupt pending, including the RxOverrun and RxFIFIOver
+     interrupts.  This confused the RTL8139 thoroughly.  It destroyed the
+     Rx ring contents by dumping the 2K FIFO contents right where we wanted to
+     get the next packet.  Oh well, what fun.
+
+  18 Jan 2000   mdc@etherboot.org (Marty Connor)
+     Drastically simplified error handling.  Basically, if any error
+     in transmission or reception occurs, the card is reset.
+     Also, pointed all transmit descriptors to the same buffer to
+     save buffer space.  This should decrease driver size and avoid
+     corruption because of exceeding 32K during runtime.
+
+  28 Jul 1999   (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
+     rtl_poll was quite broken: it used the RxOK interrupt flag instead
+     of the RxBufferEmpty flag which often resulted in very bad
+     transmission performace - below 1kBytes/s.

+ *                                       file
+ * 96-01-19		 Erik Stahlman	 polished this up some, and added
+ *                                       better error handling
+ * 98-09-25              Daniel Engström adjusted for Etherboot
+ * 98-09-27              Daniel Engström moved some static strings back to the
+ *                                       main .c file

+ * A description of the SMC registers is probably in order here,

+ *
+ * Basically, the chip has 4 banks of registers ( 0 to 3 ), which
+ * are accessed by writing a number into the BANK_SELECT register
+ * ( I also use a SMC_SELECT_BANK macro for this ).
+ *
+ * The banks are configured so that for most purposes, bank 2 is all
+ * that is needed for simple run time tasks.

+
+  As of April 2001 this driver should support most tulip cards that 
+  the Linux tulip driver supports because Donald Becker's Linux media 
+  detection code is now included.
+
+  Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
+  Linux Tulip Driver. Supports N-Way speed auto-configuration on
+  MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
+  based on the Macronix MX987x5 chip, such as the SOHOware Fast
+  model SFA110A, and the LinkSYS model LNE100TX. The NetGear
+  model FA310X, based on the LC82C168 chip is supported.
+  The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
+  chipset is supported. Also, Davicom DM9102's.

+  08 Feb 2005  Ramesh Chander chhabaramesh at yahoo.co.in added table entries
+               for SGThomson STE10/100A
+  07 Sep 2003  timlegge	Multicast Support Added
+  11 Apr 2001  mdc     [patch to etherboot 4.7.24]
+     Major rewrite to include Linux tulip driver media detection
+     code.  This driver should support a lot more cards now.
+  16 Jul 2000  mdc     0.75b11
+     Added support for ADMtek 0985 Centaur-P, a "Comet" tulip clone
+     which is used on the LinkSYS LNE100TX v4.x cards.  We already
+     support LNE100TX v2.0 cards, which use a different controller.
+  04 Jul 2000   jam     ?
+     Added test of status after receiving a packet from the card.
+     Also uncommented the tulip_disable routine.  Stray packets
+     seemed to be causing problems.
+  27 Apr 2000   njl     ?
+  29 Feb 2000   mdc     0.75b7
+     Increased reset delay to 3 seconds because Macronix cards seem to
+     need more reset time before card comes back to a usable state.
+  26 Feb 2000   mdc     0.75b6
+     Added a 1 second delay after initializing the transmitter because
+     some cards seem to need the time or they drop the first packet 
+     transmitted.
+  23 Feb 2000   mdc     0.75b5
+     removed udelay code and used currticks() for more reliable delay
+     code in reset pause and sanity timeouts.  Added function prototypes
+     and TX debugging code.
+  21 Feb 2000   mdc     patch to Etherboot 4.4.3
+     Incorporated patches from Bob Edwards and Paul Mackerras of 
+     Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
+     and udelay.  We now wait for packet transmission to complete
+     (or sanity timeout).
+  04 Feb 2000   Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
+     patch to tulip.c that implements the automatic selection of the MII
+     interface on cards using the Intel/DEC 21143 reference design, in
+     particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
+     21143-PD chipset.
+  11 Jan 2000   mdc     0.75b4
+     Added support for NetGear FA310TX card based on the LC82C168
+     chip.  This should also support Lite-On LC82C168 boards.
+     Added simple MII support. Re-arranged code to better modularize
+     initializations.
+  04 Dec 1999   mdc     0.75b3
+     Added preliminary support for LNE100TX PCI cards.  Should work for
+     PNIC2 cards. No MII support, but single interface (RJ45) tulip
+     cards seem to not care.
+  03 Dec 1999   mdc     0.75b2
+     Renamed from mx987x5 to tulip, merged in original tulip init code
+     from tulip.c to support other tulip compatible cards.
+  02 Dec 1999   mdc     0.75b1
+     Released Beta MX987x5 Driver for code review and testing to netboot
+     and thinguin mailing lists.

+ *
+ * This is the etherboot driver for cards based on Winbond W89c840F chip.
+ *
+ * It was written from skeleton source, with Donald Becker's winbond-840.c
+ * kernel driver as a guideline. Mostly the w89c840 related definitions
+ * and the lower level routines have been cut-and-pasted into this source.
+ *
+ * Frankly speaking, about 90% of the code was obtained using cut'n'paste
+ * sequence :) while the remainder appeared while brainstorming
+ * Linux Kernel 2.4.0-testX source code. Thanks, Donald and Linus!
+ *
+ * There was a demand for using this card in a rather large
+ * remote boot environment at MSKP OVTI Lab of
+ * Moscow Institute for Physics and Technology (MIPT) -- http://www.mipt.ru/
+ * so you may count that for motivation.

+ * 24-bit address.  Some devices support the "48-bit address feature
+ * set" (LBA48), in which case each of these byte-wide registers is
+ * actually a two-entry FIFO, and the "previous" byte pushed into the
+ * FIFO is used as the corresponding high-order byte.  So, to set up
+ * the 48-bit address 0x123456abcdef, you would issue
+ *
+ *     0x56 -> LBA Low register
+ *     0xef -> LBA Low register
+ *     0x34 -> LBA Mid register
+ *     0xcd -> LBA Mid register
+ *     0x12 -> LBA High register
+ *     0xab -> LBA High register
+ *
+ * This structure encapsulates this information by providing a single
+ * 64-bit integer in native byte order, unioned with bytes named so
+ * that the sequence becomes
+ *
+ *     low_prev  -> LBA Low register
+ *     low_cur   -> LBA Low register
+ *     mid_prev  -> LBA Mid register
+ *     mid_cur   -> LBA Mid register
+ *     high_prev -> LBA High register
+ *     high_cur  -> LBA High register
+ *
+ * Just to complicate matters further, in non-LBA48 mode it is
+ * possible to have a 28-bit address, in which case bits 27:24 must be
+ * written into the low four bits of the Device register.

+/** @page ifdef_harmful #ifdef considered harmful
+ *
+ * Overuse of @c #ifdef has long been a problem in Etherboot.
+ * Etherboot provides a rich array of features, but all these features
+ * take up valuable space in a ROM image.  The traditional solution to
+ * this problem has been for each feature to have its own @c #ifdef
+ * option, allowing the feature to be compiled in only if desired.
+ *
+ * The problem with this is that it becomes impossible to compile, let
+ * alone test, all possible versions of Etherboot.  Code that is not
+ * typically used tends to suffer from bit-rot over time.  It becomes
+ * extremely difficult to predict which combinations of compile-time
+ * options will result in code that can even compile and link
+ * correctly.
+ *
+ * To solve this problem, we have adopted a new approach from
+ * Etherboot 5.5 onwards.  @c #ifdef is now "considered harmful", and
+ * its use should be minimised.  Separate features should be
+ * implemented in separate @c .c files, and should \b always be
+ * compiled (i.e. they should \b not be guarded with a @c #ifdef @c
+ * MY_PET_FEATURE statement).  By making (almost) all code always
+ * compile, we avoid the problem of bit-rot in rarely-used code.
+ *
+ * The file config.h, in combination with the @c make command line,
+ * specifies the objects that will be included in any particular build
+ * of Etherboot.  For example, suppose that config.h includes the line
+ *
+ * @code
+ *
+ *   #define CONSOLE_SERIAL
+ *   #define DOWNLOAD_PROTO_TFTP
+ *
+ * @endcode
+ *
+ * When a particular Etherboot image (e.g. @c bin/rtl8139.zdsk) is
+ * built, the options specified in config.h are used to drag in the
+ * relevant objects at link-time.  For the above example, serial.o and
+ * tftp.o would be linked in.
+ *
+ * There remains one problem to solve: how do these objects get used?
+ * Traditionally, we had code such as
+ *
+ * @code
+ *
+ *    #ifdef CONSOLE_SERIAL
+ *      serial_init();
+ *    #endif
+ *
+ * @endcode
+ *
+ * in main.c, but this reintroduces @c #ifdef and so is a Bad Idea.
+ * We cannot simply remove the @c #ifdef and make it
+ *
+ * @code
+ *
+ *   serial_init();
+ *
+ * @endcode
+ *
+ * because then serial.o would end up always being linked in.
+ *
+ * The solution is to use @link tables.h linker tables @endlink.
+ *
+ */
+
+/** @file
+ *
+ * Linker tables
+ *
+ * Read @ref ifdef_harmful first for some background on the motivation
+ * for using linker tables.
+ *
+ * This file provides macros for dealing with linker-generated tables
+ * of fixed-size symbols.  We make fairly extensive use of these in
+ * order to avoid @c #ifdef spaghetti and/or linker symbol pollution.
+ * For example, instead of having code such as
+ *
+ * @code
+ *
+ *    #ifdef CONSOLE_SERIAL
+ *      serial_init();
+ *    #endif
+ *
+ * @endcode
+ *
+ * we make serial.c generate an entry in the initialisation function
+ * table, and then have a function call_init_fns() that simply calls
+ * all functions present in this table.  If and only if serial.o gets
+ * linked in, then its initialisation function will be called.  We
+ * avoid linker symbol pollution (i.e. always dragging in serial.o
+ * just because of a call to serial_init()) and we also avoid @c
+ * #ifdef spaghetti (having to conditionalise every reference to
+ * functions in serial.c).
+ *
+ * The linker script takes care of assembling the tables for us.  All
+ * our table sections have names of the format @c .tbl.NAME.NN where
+ * @c NAME designates the data structure stored in the table (e.g. @c
+ * init_fns) and @c NN is a two-digit decimal number used to impose an
+ * ordering upon the tables if required.  @c NN=00 is reserved for the
+ * symbol indicating "table start", and @c NN=99 is reserved for the
+ * symbol indicating "table end".
+ *
+ * As an example, suppose that we want to create a "frobnicator"
+ * feature framework, and allow for several independent modules to
+ * provide frobnicating services.  Then we would create a frob.h
+ * header file containing e.g.
+ *
+ * @code
+ *
+ *   struct frobnicator {
+ *      const char *name;		// Name of the frobnicator
+ *	void ( *frob ) ( void ); 	// The frobnicating function itself
+ *   };
+ *
+ *   #define FROBNICATORS __table ( struct frobnicator, "frobnicators" )
+ *
+ *   #define __frobnicator __table_entry ( FROBNICATORS, 01 )
+ *
+ * @endcode
+ *
+ * Any module providing frobnicating services would look something
+ * like
+ *
+ * @code
+ *
+ *   #include "frob.h"
+ *
+ *   static void my_frob ( void ) {
+ *	// Do my frobnicating
+ *	...
+ *   }
+ *
+ *   struct frob my_frobnicator __frobnicator = {
+ *	.name = "my_frob",
+ *	.frob = my_frob,
+ *   };
+ *
+ * @endcode
+ *
+ * The central frobnicator code (frob.c) would use the frobnicating
+ * modules as follows
+ *
+ * @code
+ *
+ *   #include "frob.h"
+ *
+ *   // Call all linked-in frobnicators
+ *   void frob_all ( void ) {
+ *	struct frob *frob;
+ *
+ *	for_each_table ( frob, FROBNICATORS ) {
+ *         printf ( "Calling frobnicator \"%s\"\n", frob->name );
+ *	   frob->frob ();
+ *	}
+ *   }
+ *
+ * @endcode
+ *
+ * See init.h and init.c for a real-life example.

+/** @page rc80211 Rate control philosophy
+ *
+ * We want to maximize our transmission speed, to the extent that we
+ * can do that without dropping undue numbers of packets. We also
+ * don't want to take up very much code space, so our algorithm has to
+ * be pretty simple
+ *
+ * When we receive a packet, we know what rate it was transmitted at,
+ * and whether it had to be retransmitted to get to us.
+ *
+ * When we send a packet, we hear back how many times it had to be
+ * retried to get through, and whether it got through at all.
+ *
+ * Indications of TX success are more reliable than RX success, but RX
+ * information helps us know where to start.
+ *
+ * To handle all of this, we keep for each rate and each direction (TX
+ * and RX separately) some state information for the most recent
+ * packets on that rate and the number of packets for which we have
+ * information. The state is a 32-bit unsigned integer in which two
+ * bits represent a packet: 11 if it went through well, 10 if it went
+ * through with one retry, 01 if it went through with more than one
+ * retry, or 00 if it didn't go through at all. We define the
+ * "goodness" for a particular (rate, direction) combination as the
+ * sum of all the 2-bit fields, times 33, divided by the number of
+ * 2-bit fields containing valid information (16 except when we're
+ * starting out). The number produced is between 0 and 99; we use -1
+ * for rates with less than 4 RX packets or 1 TX, as an indicator that
+ * we do not have enough information to rely on them.
+ *
+ * In deciding which rates are best, we find the weighted average of
+ * TX and RX goodness, where the weighting is by number of packets
+ * with data and TX packets are worth 4 times as much as RX packets.
+ * The weighted average is called "net goodness" and is also a number
+ * between 0 and 99.  If 3 consecutive packets fail transmission
+ * outright, we automatically ratchet down the rate; otherwise, we
+ * switch to the best rate whenever the current rate's goodness falls
+ * below some threshold, and try increasing our rate when the goodness
+ * is very high.
+ *
+ * This system is optimized for gPXE's style of usage. Because normal
+ * operation always involves receiving something, we'll make our way
+ * to the best rate pretty quickly. We tend to follow the lead of the
+ * sending AP in choosing rates, but we won't use rates for long that
+ * don't work well for us in transmission. We assume gPXE won't be
+ * running for long enough that rate patterns will change much, so we
+ * don't have to keep time counters or the like.  And if this doesn't
+ * work well in practice there are many ways it could be tweaked.
+ *
+ * To avoid staying at 1Mbps for a long time, we don't track any
+ * transmitted packets until we've set our rate based on received
+ * packets.

+ * Scalable Local Area Multicast protocol
+ *
+ * The SLAM protocol is supported only by Etherboot; it was designed
+ * and implemented by Eric Biederman.  A server implementation is
+ * available in contrib/mini-slamd.  There does not appear to be any
+ * documentation beyond a few sparse comments in Etherboot's
+ * proto_slam.c.
+ *
+ * SLAM packets use three types of data field:
+ *
+ *  Nul : A single NUL (0) byte, used as a list terminator
+ *
+ *  Raw : A block of raw data
+ *
+ *  Int : A variable-length integer, in big-endian order.  The length
+ *        of the integer is encoded in the most significant three bits.
+ *
+ * Packets received by the client have the following layout:
+ *
+ *  Int : Transaction identifier.  This is an opaque value.
+ *
+ *  Int : Total number of bytes in the transfer.
+ *
+ *  Int : Block size, in bytes.
+ *
+ *  Int : Packet sequence number within the transfer (if this packet
+ *        contains data).
+ *
+ *  Raw : Packet data (if this packet contains data).
+ *
+ * Packets transmitted by the client consist of a run-length-encoded
+ * representation of the received-blocks bitmap, looking something
+ * like:
+ *
+ *  Int : Number of consecutive successfully-received packets
+ *  Int : Number of consecutive missing packets
+ *  Int : Number of consecutive successfully-received packets
+ *  Int : Number of consecutive missing packets
+ *  ....
+ *  Nul

+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it

+Build instructions:
+
+  - Copy grub-extras in a subdirectory of your grub2 checkout.
+    For example, "grub-extras".
+
+  - Export GRUB_CONTRIB environment variable to point to this directory.
+
+  - Build GRUB as usual.

+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+grub-extras is meant to be used as an overlay on grub2 source tree.
+
+Build instructions:
+
+  - Copy grub-extras in a subdirectory of your grub2 checkout.
+    For example, "grub-extras".
+
+  - Export GRUB_CONTRIB environment variable to point to this directory.
+
+  - Build GRUB as usual.

+** Implementation of tables (aka arrays, objects, or hash tables).
+** Tables keep its elements in two parts: an array part and a hash part.
+** Non-negative integer keys are all candidates to be kept in the array
+** part. The actual size of the array is the largest `n' such that at
+** least half the slots between 0 and n are in use.
+** Hash uses a mix of chained scatter table with Brent's variation.
+** A main invariant of these tables is that, if an element is not
+** in its main position (i.e. the `original' position that its hash gives
+** to it), then the colliding element is in its own main position.
+** Hence even when the load factor reaches 100%, performance remains good.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+; Features: Uses LBA and calculates all variables from BPB/EBPB data,
+; thus making partition move / resize / image-restore easier. FreeDOS
+; can boot from FAT32 partitions which start > 8 GB boundary with this
+; boot sector. Disk geometry knowledge is not needed for booting.
+;
+; Windows uses 2-3 sectors for booting (sector stage, statistics sector,
+; filesystem stage). Only using 1 sector for FreeDOS makes multi-booting
+; of FreeDOS and Windows on the same filesystem easier.
+;
+; Requirements: LBA BIOS and 386 or better CPU. Use the older CHS-only
+; boot sector if you want FAT32 on really old PCs (problems: you cannot
+; boot from > 8 GB boundary, cannot move / resize / ... without applying
+; SYS again if you use the CHS-only FAT32 boot sector).
+;
+; FAT12 / FAT16 hints: Use the older CHS-only boot sector unless you
+; have to boot from > 8 GB. The LBA-and-CHS FAT12 / FAT16 boot sector
+; needs applying SYS again after move / resize / ... a variant of that
+; boot sector without CHS support but with better move / resize / ...
+; support would be good for use on LBA harddisks.
+
+
+; Memory layout for the FreeDOS FAT32 single stage boot process:
+
+;	...
+;	|-------| 1FE0:7E00
+;	|BOOTSEC|
+;	|RELOC.	|
+;	|-------| 1FE0:7C00
+;	...
+;	|-------| 2000:0200
+;	|  FAT  | (only 1 sector buffered)
+;	|-------| 2000:0000
+;	...
+;	|-------| 0000:7E00
+;	|BOOTSEC| overwritten by the kernel, so the
+;	|ORIGIN | bootsector relocates itself up...
+;	|-------| 0000:7C00
+;	...
+;	|-------|
+;	|KERNEL	| maximum size 134k (overwrites bootsec origin)
+;	|LOADED	| (holds 1 sector directory buffer before kernel load)
+;	|-------| 0060:0000
+;	...

+_Description: Chainload from menu.lst?
+ GRUB upgrade scripts have detected a GRUB Legacy setup in /boot/grub.
+ .
+ In order to replace the Legacy version of GRUB in your system, it is
+ recommended that /boot/grub/menu.lst is adjusted to load a GRUB 2 boot
+ image from your existing GRUB Legacy setup. This step can be automatically
+ performed now.
+ .
+ It's recommended that you accept chainloading GRUB 2 from menu.lst, and
+ verify that the new GRUB 2 setup works before it is written to the MBR
+ (Master Boot Record).
+ .
+ Whatever your decision, you can replace the old MBR image with GRUB 2
+ later by issuing the following command as root:

+_Description: GRUB install devices:
+ The grub-pc package is being upgraded. This menu allows you to select which
+ devices you'd like grub-install to be automatically run for, if any.
+ .
+ Running grub-install automatically is recommended in most situations, to
+ prevent the installed GRUB core image from getting out of sync with GRUB
+ modules or grub.cfg.
+ .
+ If you're unsure which drive is designated as boot drive by your BIOS, it is
+ often a good idea to install GRUB to all of them.
+ .
+ Note: it is possible to install GRUB to partition boot records as well, and
+ some appropriate partitions are offered here. However, this forces GRUB to
+ use the blocklist mechanism, which makes it less reliable, and therefore is
+ not recommended.

+_Description: Writing GRUB to boot device failed - try again?
+ GRUB failed to install to the following devices:
+ .
+ ${FAILED_DEVICES}
+ .
+ You may be able to install GRUB to some other device, although you should
+ check that your system will boot from that device. Otherwise, the upgrade
+ from GRUB Legacy will be canceled.
+
+Template: grub-pc/install_devices_empty
+Type: boolean
+Default: false
+_Description: Continue without installing GRUB?
+ You chose not to install GRUB to any devices. If you continue, the boot
+ loader may not be properly configured, and when this computer next starts
+ up it will use whatever was previously in the boot sector. If there is an
+ earlier version of GRUB 2 in the boot sector, it may be unable to load
+ modules or handle the current configuration file.
+ .
+ If you are already using a different boot loader and want to carry on
+ doing so, or if this is a special environment where you do not need a boot
+ loader, then you should continue anyway. Otherwise, you should install
+ GRUB somewhere.

+_Description: Remove GRUB 2 from /boot/grub?
+ Do you want to have all GRUB 2 files removed from /boot/grub?
+ .
+ This will make the system unbootable unless another boot loader is
+ installed.
+
+Template: grub-pc/mixed_legacy_and_grub2
+Type: boolean
+Default: true

+_Description: Finish conversion to GRUB 2 now?
+ This system still has files from the GRUB Legacy boot loader installed, but
+ it now also has GRUB 2 boot records installed on these disks:
+ .
+ ${DISKS}
+ .
+ It seems likely that GRUB Legacy is no longer in use, and that you should
+ instead upgrade the GRUB 2 images on these disks and finish the conversion
+ to GRUB 2 by removing old GRUB Legacy files. If you do not upgrade these
+ GRUB 2 images, then they may be incompatible with the new packages and
+ cause your system to stop booting properly.
+ .
+ You should generally finish the conversion to GRUB 2 unless these boot
+ records were created by a GRUB 2 installation on some other operating
+ system.

+From 9c8e1c85ec9971f2c6bb9a8a7530e94f7dbec14a Mon Sep 17 00:00:00 2001
+From: Chris Coulson <chris.coulson@canonical.com>
+Date: Tue, 5 Apr 2022 10:02:04 +0100
+Subject: loader/efi/chainloader: Simplify the loader state
+
+The chainloader command retains the source buffer and device path passed
+to LoadImage(), requiring the unload hook passed to grub_loader_set() to
+free them. It isn't required to retain this state though - they aren't
+required by StartImage() or anything else in the boot hook, so clean them
+up before grub_cmd_chainloader() finishes.

+Subject: commands/boot: Add API to pass context to loader
+
+Loaders rely on global variables for saving context which is consumed
+in the boot hook and freed in the unload hook. In the case where a loader
+command is executed twice, calling grub_loader_set a second time executes
+the unload hook, but in some cases this runs when the loader's global
+context has already been updated, resulting in the updated context being
+freed and potential use-after-free bugs when the boot hook is subsequently
+called.
+
+This adds a new API (grub_loader_set_ex) which allows a loader to specify
+context that is passed to its boot and unload hooks. This is an alternative
+to requiring that loaders call grub_loader_unset before mutating their
+global context.

+Subject: kern/efi/sb: Reject non-kernel files in the shim_lock verifier
+
+We must not allow other verifiers to pass things like the GRUB modules.
+Instead of maintaining a blocklist, maintain an allowlist of things
+that we do not care about.
+
+This allowlist really should be made reusable, and shared by the
+lockdown verifier, but this is the minimal patch addressing
+security concerns where the TPM verifier was able to mark modules
+as verified (or the OpenPGP verifier for that matter), when it
+should not do so on shim-powered secure boot systems.

+Subject: video/readers/png: Drop greyscale support to fix heap out-of-bounds
+ write
+
+A 16-bit greyscale PNG without alpha is processed in the following loop:
+
+      for (i = 0; i < (data->image_width * data->image_height);
+	   i++, d1 += 4, d2 += 2)
+	{
+	  d1[R3] = d2[1];
+	  d1[G3] = d2[1];
+	  d1[B3] = d2[1];
+	}
+
+The increment of d1 is wrong. d1 is incremented by 4 bytes per iteration,
+but there are only 3 bytes allocated for storage. This means that image
+data will overwrite somewhat-attacker-controlled parts of memory - 3 bytes
+out of every 4 following the end of the image.
+
+This has existed since greyscale support was added in 2013 in commit
+3ccf16dff98f (grub-core/video/readers/png.c: Support grayscale).
+
+Saving starfield.png as a 16-bit greyscale image without alpha in the gimp
+and attempting to load it causes grub-emu to crash - I don't think this code
+has ever worked.
+
+Delete all PNG greyscale support.
+

+Subject: video/readers/png: Avoid heap OOB R/W inserting huff table items
+
+In fuzzing we observed crashes where a code would attempt to be inserted
+into a huffman table before the start, leading to a set of heap OOB reads
+and writes as table entries with negative indices were shifted around and
+the new code written in.
+
+Catch the case where we would underflow the array and bail.

+Subject: video/readers/jpeg: Block int underflow -> wild pointer write
+
+Certain 1 px wide images caused a wild pointer write in
+grub_jpeg_ycrcb_to_rgb(). This was caused because in grub_jpeg_decode_data(),
+we have the following loop:
+
+for (; data->r1 < nr1 && (!data->dri || rst);
+     data->r1++, data->bitmap_ptr += (vb * data->image_width - hb * nc1) * 3)
+
+We did not check if vb * width >= hb * nc1.
+
+On a 64-bit platform, if that turns out to be negative, it will underflow,
+be interpreted as unsigned 64-bit, then be added to the 64-bit pointer, so
+we see data->bitmap_ptr jump, e.g.:
+
+0x6180_0000_0480 to
+0x6181_0000_0498
+     ^
+     ~--- carry has occurred and this pointer is now far away from
+          any object.
+
+On a 32-bit platform, it will decrement the pointer, creating a pointer
+that won't crash but will overwrite random data.
+
+Catch the underflow and error out.

+In some cases attempting to display arbitrary binary strings leads
+to ASAN splats reading the widthspec array out of bounds.
+
+Check the index. If it would be out of bounds, return a width of 1.

+great display of arbitrary binary data, and it's certainly not worse than

+Subject: net/dns: Fix double-free addresses on corrupt DNS response
+
+grub_net_dns_lookup() takes as inputs a pointer to an array of addresses
+("addresses") for the given name, and pointer to a number of addresses
+("naddresses"). grub_net_dns_lookup() is responsible for allocating
+"addresses", and the caller is responsible for freeing it if
+"naddresses" > 0.
+
+The DNS recv_hook will sometimes set and free the addresses array,
+for example if the packet is too short:
+
+      if (ptr + 10 >= nb->tail)
+	{
+	  if (!*data->naddresses)
+	    grub_free (*data->addresses);
+	  grub_netbuff_free (nb);
+	  return GRUB_ERR_NONE;
+	}
+
+Later on the nslookup command code unconditionally frees the "addresses"
+array. Normally this is fine: the array is either populated with valid
+data or is NULL. But in these sorts of error cases it is neither NULL
+nor valid and we get a double-free.
+
+Only free "addresses" if "naddresses" > 0.
+
+It looks like the other use of grub_net_dns_lookup() is not affected.

+Subject: net/tftp: Prevent a UAF and double-free from a failed seek
+
+A malicious tftp server can cause UAFs and a double free.
+
+An attempt to read from a network file is handled by grub_net_fs_read(). If
+the read is at an offset other than the current offset, grub_net_seek_real()
+is invoked.
+
+In grub_net_seek_real(), if a backwards seek cannot be satisfied from the
+currently received packets, and the underlying transport does not provide
+a seek method, then grub_net_seek_real() will close and reopen the network
+protocol layer.
+
+For tftp, the ->close() call goes to tftp_close() and frees the tftp_data_t
+file->data. The file->data pointer is not nulled out after the free.
+
+If the ->open() call fails, the file->data will not be reallocated and will
+continue point to a freed memory block. This could happen from a server
+refusing to send the requisite ack to the new tftp request, for example.
+
+The seek and the read will then fail, but the grub_file continues to exist:
+the failed seek does not necessarily cause the entire file to be thrown
+away (e.g. where the file is checked to see if it is gzipped/lzio/xz/etc.,
+a read failure is interpreted as a decompressor passing on the file, not as
+an invalidation of the entire grub_file_t structure).
+
+This means subsequent attempts to read or seek the file will use the old
+file->data after free. Eventually, the file will be close()d again and
+file->data will be freed again.
+
+Mark a net_fs file that doesn't reopen as broken. Do not permit read() or
+close() on a broken file (seek is not exposed directly to the file API -
+it is only called as part of read, so this blocks seeks as well).
+
+As an additional defence, null out the ->data pointer if tftp_open() fails.
+That would have lead to a simple null pointer dereference rather than
+a mess of UAFs.
+
+This may affect other protocols, I haven't checked.

+
+Under tftp errors, we print a tftp error message from the tftp header.
+However, the tftph pointer is a pointer inside nb, the netbuff. Previously,
+we were freeing the nb and then dereferencing it. Don't do that, use it
+and then free it later.
+
+This isn't really _bad_ per se, especially as we're single-threaded, but

+Subject: net/http: Fix OOB write for split http headers
+
+GRUB has special code for handling an http header that is split
+across two packets.
+
+The code tracks the end of line by looking for a "\n" byte. The
+code for split headers has always advanced the pointer just past the
+end of the line, whereas the code that handles unsplit headers does
+not advance the pointer. This extra advance causes the length to be
+one greater, which breaks an assumption in parse_line(), leading to
+it writing a NUL byte one byte past the end of the buffer where we
+reconstruct the line from the two packets.
+
+It's conceivable that an attacker controlled set of packets could
+cause this to zero out the first byte of the "next" pointer of the
+grub_mm_region structure following the current_line buffer.
+
+Do not advance the pointer in the split header case.

+Subject: fs/f2fs: Do not read past the end of nat bitmap
+
+A corrupt f2fs filesystem could have a block offset or a bitmap
+offset that would cause us to read beyond the bounds of the nat
+bitmap.
+
+Introduce the nat_bitmap_size member in grub_f2fs_data which holds
+the size of nat bitmap.
+
+Set the size when loading the nat bitmap in nat_bitmap_ptr(), and
+catch when an invalid offset would create a pointer past the end of
+the allocated space.
+
+Check against the bitmap size in grub_f2fs_test_bit() test bit to avoid
+reading past the end of the nat bitmap.

+Subject: fs/f2fs: Do not copy file names that are too long
+
+A corrupt f2fs file system might specify a name length which is greater
+than the maximum name length supported by the GRUB f2fs driver.
+
+We will allocate enough memory to store the overly long name, but there
+are only F2FS_NAME_LEN bytes in the source, so we would read past the end
+of the source.
+
+While checking directory entries, do not copy a file name with an invalid
+length.

+Subject: fs/btrfs: Fix several fuzz issues with invalid dir item sizing
+
+According to the btrfs code in Linux, the structure of a directory item
+leaf should be of the form:
+
+  |struct btrfs_dir_item|name|data|
+
+in GRUB the name len and data len are in the grub_btrfs_dir_item
+structure's n and m fields respectively.
+
+The combined size of the structure, name and data should be less than
+the allocated memory, a difference to the Linux kernel's struct
+btrfs_dir_item is that the grub_btrfs_dir_item has an extra field for
+where the name is stored, so we adjust for that too.

+Subject: fs/btrfs: Fix more ASAN and SEGV issues found with fuzzing
+
+The fuzzer is generating btrfs file systems that have chunks with
+invalid combinations of stripes and substripes for the given RAID
+configurations.
+
+After examining the Linux kernel fs/btrfs/tree-checker.c code, it
+appears that sub-stripes should only be applied to RAID10, and in that
+case there should only ever be 2 of them.
+
+Similarly, RAID single should only have 1 stripe, and RAID1/1C3/1C4
+should have 2. 3 or 4 stripes respectively, which is what redundancy
+corresponds.
+
+Some of the chunks ended up with a size of 0, which grub_malloc() still
+returned memory for and in turn generated ASAN errors later when
+accessed.
+
+While it would be possible to specifically limit the number of stripes,
+a more correct test was on the combination of the chunk item, and the
+number of stripes by the size of the chunk stripe structure in
+comparison to the size of the chunk itself.

+Subject: fs/btrfs: Fix more fuzz issues related to chunks
+
+The corpus was generating issues in grub_btrfs_read_logical() when
+attempting to iterate over stripe entries in the superblock's
+bootmapping.
+
+In most cases the reason for the failure was that the number of stripes
+in chunk->nstripes exceeded the possible space statically allocated in
+superblock bootmapping space. Each stripe entry in the bootmapping block
+consists of a grub_btrfs_key followed by a grub_btrfs_chunk_stripe.
+
+Another issue that came up was that while calculating the chunk size,
+in an earlier piece of code in that function, depending on the data
+provided in the btrfs file system, it would end up calculating a size
+that was too small to contain even 1 grub_btrfs_chunk_item, which is
+obviously invalid too.

+Subject: bootp: Add processing DHCPACK packet from HTTP Boot
+
+The vendor class identifier with the string "HTTPClient" is used to denote the
+packet as responding to HTTP boot request. In DHCP4 config, the filename for
+HTTP boot is the URL of the boot file while for PXE boot it is the path to the
+boot file. As a consequence, the next-server becomes obseleted because the HTTP
+URL already contains the server address for the boot file. For DHCP6 config,
+there's no difference definition in existing config as dhcp6.bootfile-url can
+be used to specify URL for both HTTP and PXE boot file.
+
+This patch adds processing for "HTTPClient" vendor class identifier in DHCPACK
+packet by treating it as HTTP format, not as the PXE format.

+Subject: [PATCH 01/14] video/readers: Add artificial limit to image dimensions
+
+In grub-core/video/readers/jpeg.c, the height and width of a JPEG image don't
+have an upper limit for how big the JPEG image can be. In Coverity, this is
+getting flagged as an untrusted loop bound. This issue can also seen in PNG and
+TGA format images as well but Coverity isn't flagging it. To prevent this, the
+constant IMAGE_HW_MAX_PX is being added to include/grub/bitmap.h, which has

+Subject: [PATCH 03/14] font: Fix size overflow in
+ grub_font_get_glyph_internal()
+
+The length of memory allocation and file read may overflow. This patch
+fixes the problem by using safemath macros.
+
+There is a lot of code repetition like "(x * y + 7) / 8". It is unsafe
+if overflow happens. This patch introduces grub_video_bitmap_calc_1bpp_bufsz().
+It is safe replacement for such code. It has safemath-like prototype.
+
+This patch also introduces grub_cast(value, pointer), it casts value to
+typeof(*pointer) then store the value to *pointer. It returns true when
+overflow occurs or false if there is no overflow. The semantics of arguments
+and return value are designed to be consistent with other safemath macros.

+In fact it can't overflow at all because glyph_id->ncomb is only 8-bit

+Subject: [PATCH 07/14] font: Fix integer overflow in BMP index
+
+The BMP index (font->bmp_idx) is designed as a reverse lookup table of
+char entries (font->char_index), in order to speed up lookups for BMP
+chars (i.e. code < 0x10000). The values in BMP index are the subscripts
+of the corresponding char entries, stored in grub_uint16_t, while 0xffff
+means not found.
+
+This patch fixes the problem of large subscript truncated to grub_uint16_t,
+leading BMP index to return wrong char entry or report false miss. The
+code now checks for bounds and uses BMP index as a hint, and fallbacks
+to binary-search if necessary.
+
+On the occasion add a comment about BMP index is initialized to 0xffff.

+Subject: [PATCH 09/14] kern/efi/sb: Enforce verification of font files
+
+As a mitigation and hardening measure enforce verification of font
+files. Then only trusted font files can be load. This will reduce the
+attack surface at cost of losing the ability of end-users to customize
+fonts if e.g. UEFI Secure Boot is enabled. Vendors can always customize
+fonts because they have ability to pack fonts into their GRUB bundles.
+
+This goal is achieved by:
+
+  * Removing GRUB_FILE_TYPE_FONT from shim lock verifier's
+    skip-verification list.
+
+  * Adding GRUB_FILE_TYPE_FONT to lockdown verifier's defer-auth list,
+    so font files must be verified by a verifier before they can be loaded.

+Subject: [PATCH 10/14] fbutil: Fix integer overflow
+
+Expressions like u64 = u32 * u32 are unsafe because their products are
+truncated to u32 even if left hand side is u64. This patch fixes all
+problems like that one in fbutil.
+
+To get right result not only left hand side have to be u64 but it's also
+necessary to cast at least one of the operands of all leaf operators of
+right hand side to u64, e.g. u64 = u32 * u32 + u32 * u32 should be
+u64 = (u64)u32 * u32 + (u64)u32 * u32.
+
+For 1-bit bitmaps grub_uint64_t have to be used. It's safe because any
+combination of values in (grub_uint64_t)u32 * u32 + u32 expression will
+not overflow grub_uint64_t.
+
+Other expressions like ptr + u32 * u32 + u32 * u32 are also vulnerable.
+They should be ptr + (grub_addr_t)u32 * u32 + (grub_addr_t)u32 * u32.
+
+This patch also adds a comment to grub_video_fb_get_video_ptr() which
+says it's arguments must be valid and no sanity check is performed
+(like its siblings in grub-core/video/fb/fbutil.c).

+Subject: [PATCH 11/14] font: Fix an integer underflow in blit_comb()
+
+The expression (ctx.bounds.height - combining_glyphs[i]->height) / 2 may
+evaluate to a very big invalid value even if both ctx.bounds.height and
+combining_glyphs[i]->height are small integers. For example, if
+ctx.bounds.height is 10 and combining_glyphs[i]->height is 12, this
+expression evaluates to 2147483647 (expected -1). This is because
+coordinates are allowed to be negative but ctx.bounds.height is an
+unsigned int. So, the subtraction operates on unsigned ints and
+underflows to a very big value. The division makes things even worse.
+The quotient is still an invalid value even if converted back to int.
+
+This patch fixes the problem by casting ctx.bounds.height to int. As
+a result the subtraction will operate on int and grub_uint16_t which
+will be promoted to an int. So, the underflow will no longer happen. Other
+uses of ctx.bounds.height (and ctx.bounds.width) are also casted to int,
+to ensure coordinates are always calculated on signed integers.

+Subject: [PATCH 12/14] font: Harden grub_font_blit_glyph() and
+ grub_font_blit_glyph_mirror()
+
+As a mitigation and hardening measure add sanity checks to
+grub_font_blit_glyph() and grub_font_blit_glyph_mirror(). This patch
+makes these two functions do nothing if target blitting area isn't fully
+contained in target bitmap. Therefore, if complex calculations in caller
+overflows and malicious coordinates are given, we are still safe because
+any coordinates which result in out-of-bound-write are rejected. However,
+this patch only checks for invalid coordinates, and doesn't provide any
+protection against invalid source glyph or destination glyph, e.g.
+mismatch between glyph size and buffer size.
+
+This hardening measure is designed to mitigate possible overflows in
+blit_comb(). If overflow occurs, it may return invalid bounding box
+during dry run and call grub_font_blit_glyph() with malicious
+coordinates during actual blitting. However, we are still safe because
+the scratch glyph itself is valid, although its size makes no sense, and
+any invalid coordinates are rejected.
+
+It would be better to call grub_fatal() if illegal parameter is detected.
+However, doing this may end up in a dangerous recursion because grub_fatal()
+would print messages to the screen and we are in the progress of drawing

+Subject: [PATCH 13/14] font: Assign null_font to glyphs in ascii_font_glyph[]
+
+The calculations in blit_comb() need information from glyph's font, e.g.
+grub_font_get_xheight(main_glyph->font). However, main_glyph->font is
+NULL if main_glyph comes from ascii_font_glyph[]. Therefore
+grub_font_get_*() crashes because of NULL pointer.
+
+There is already a solution, the null_font. So, assign it to those glyphs
+in ascii_font_glyph[].

+Subject: [PATCH 14/14] normal/charset: Fix an integer overflow in
+ grub_unicode_aglomerate_comb()
+
+The out->ncomb is a bit-field of 8 bits. So, the max possible value is 255.
+However, code in grub_unicode_aglomerate_comb() doesn't check for an
+overflow when incrementing out->ncomb. If out->ncomb is already 255,
+after incrementing it will get 0 instead of 256, and cause illegal
+memory access in subsequent processing.
+
+This patch introduces GRUB_UNICODE_NCOMB_MAX to represent the max
+acceptable value of ncomb. The code now checks for this limit and
+ignores additional combining characters when limit is reached.

+From 6e3841fc4abf50d16d819c39ac5de74ccc4de225 Mon Sep 17 00:00:00 2001

+Subject: Minimise writes to EFI variable storage
+
+Some UEFI firmware is easily provoked into running out of space in its
+variable storage.  This is usually due to certain kernel drivers (e.g.
+pstore), but regardless of the cause it can cause grub-install to fail
+because it currently asks efibootmgr to delete and re-add entries, and
+the deletion often doesn't result in an immediate garbage collection.
+Writing variables frequently also increases wear on the NVRAM which may
+have limited write cycles.  For these reasons, it's desirable to find a
+way to minimise writes while still allowing grub-install to ensure that
+a suitable boot entry exists.
+
+Unfortunately, efibootmgr doesn't offer an interface that would let
+grub-install do this.  It doesn't in general make very much effort to
+minimise writes; it doesn't allow modifying an existing Boot* variable
+entry, except in certain limited ways; and current versions don't have a
+way to export the expected variable data so that grub-install can
+compare it to the current data.  While it would be possible (and perhaps
+desirable?) to add at least some of this to efibootmgr, that would still
+leave the problem that there isn't a good upstreamable way for
+grub-install to guarantee that it has a new enough version of
+efibootmgr.  In any case, it's cumbersome and slow for grub-install to
+have to fork efibootmgr to get things done.
+
+Fortunately, a few years ago Peter Jones helpfully factored out a
+substantial part of efibootmgr to the efivar and efiboot libraries, and
+so it's now possible to have grub-install use those directly.  We still
+have to use some code from efibootmgr, but much less than would
+previously have been necessary.
+
+grub-install now reuses existing boot entries where possible, and avoids
+writing to variables when the new contents are the same as the old
+contents.  In the common upgrade case where nothing needs to change, it
+no longer writes to NVRAM at all.  It's also now slightly faster, since
+using libefivar is faster than forking efibootmgr.
+
+Fixes Debian bug #891434.

+Subject: efinet: Setting DNS server from UEFI protocol
+
+In the URI device path node, any name rahter than address can be used for
+looking up the resources so that DNS service become needed to get answer of the
+name's address. Unfortunately the DNS is not defined in any of the device path
+nodes so that we use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL
+to obtain it.
+
+These two protcols are defined the sections of UEFI specification.
+
+ 27.5 EFI IPv4 Configuration II Protocol
+ 27.7 EFI IPv6 Configuration Protocol
+
+include/grub/efi/api.h:
+Add new structure and protocol UUID of EFI_IP4_CONFIG2_PROTOCOL and
+EFI_IP6_CONFIG_PROTOCOL.
+
+grub-core/net/drivers/efi/efinet.c:
+Use the EFI_IP4_CONFIG2_PROTOCOL and EFI_IP6_CONFIG_PROTOCOL to obtain the list
+of DNS server address for IPv4 and IPv6 respectively. The address of DNS
+servers is structured into DHCPACK packet and feed into the same DHCP packet
+processing functions to ensure the network interface is setting up the same way
+it used to be.

+Subject: efinet: Setting network from UEFI device path
+
+The PXE Base Code protocol used to obtain cached PXE DHCPACK packet is no
+longer provided for HTTP Boot. Instead, we have to get the HTTP boot
+information from the device path nodes defined in following UEFI Specification
+sections.
+
+ 9.3.5.12 IPv4 Device Path
+ 9.3.5.13 IPv6 Device Path
+ 9.3.5.23 Uniform Resource Identifiers (URI) Device Path
+
+This patch basically does:
+
+include/grub/efi/api.h:
+Add new structure of Uniform Resource Identifiers (URI) Device Path
+
+grub-core/net/drivers/efi/efinet.c:
+Check if PXE Base Code is available, if not it will try to obtain the netboot
+information from the device path where the image booted from. The DHCPACK
+packet is recoverd from the information in device patch and feed into the same
+DHCP packet processing functions to ensure the network interface is setting up
+the same way it used to be.

+Subject: efinet: UEFI IPv6 PXE support
+
+When grub2 image is booted from UEFI IPv6 PXE, the DHCPv6 Reply packet is
+cached in firmware buffer which can be obtained by PXE Base Code protocol. The
+network interface can be setup through the parameters in that obtained packet.

+Subject: Do not overwrite sentinel byte in boot_params, breaks lockdown
+
+grub currently copies the entire boot_params, which includes setting
+sentinel byte to 0xff, which triggers sanitize_boot_params in the kernel
+which in turn clears various boot_params variables, including the
+indication that the bootloader chain is verified and thus the kernel
+disables lockdown mode.  According to the information on the Fedora bug
+tracker, only the information from byte 0x1f1 is necessary, so start
+copying from there instead.

+Subject: Disable gfxpayload=keep by default
+
+Setting gfxpayload=keep has been known to cause efifb to be
+inappropriately enabled.  In any case, with the current Linux kernel the
+result of this option is that early kernelspace will be unable to print
+anything to the console, so (for example) if boot fails and you end up
+dumped to an initramfs prompt, you won't be able to see anything on the
+screen.  As such it shouldn't be enabled by default in Debian, no matter
+what kernel options are enabled.
+
+gfxpayload=keep is a good idea but rather ahead of its time ...

+Subject: Add support for forcing EFI installation to the removable media path
+
+Add an extra option to grub-install "--force-extra-removable". On EFI
+platforms, this will cause an extra copy of the grub-efi image to be
+written to the appropriate removable media patch
+/boot/efi/EFI/BOOT/BOOT$ARCH.EFI as well. This will help with broken
+UEFI implementations where the firmware does not work when configured
+with new boot paths.

+It may be possible, particularly in recovery situations, to be booted
+using EFI on x86 when only the i386-pc target is installed, or on ARM
+when only the arm-uboot target is installed.  There's nothing actually
+stopping us installing i386-pc or arm-uboot from an EFI environment, and
+it's better than returning a confusing error.

+Subject: Port yaboot logic for various powerpc machine types
+
+Some powerpc machines require not updating the NVRAM.  This can be handled
+by existing grub-install command-line options, but it's friendlier to detect
+this automatically.
+
+On chrp_ibm machines, use the nvram utility rather than nvsetenv.  (This
+is possibly suitable for other machines too, but that needs to be
+verified.)

+Subject: [PATCH] kern/file: Fix error handling in grub_file_open()
+
+grub_file_open() calls grub_file_get_device_name(), but doesn't check
+the return. Instead, it checks if grub_errno is set.
+
+However, nothing initialises grub_errno here when grub_file_open()
+starts. This means that trying to open one file that doesn't exist and
+then trying to open another file that does will (incorrectly) also
+fail to open that second file.
+
+Let's fix that.

+From 0b33def5d9ace3488fa612e09a5bb813c5e3cd90 Mon Sep 17 00:00:00 2001
+From: Colin Watson <cjwatson@ubuntu.com>
+Date: Mon, 13 Jan 2014 12:13:26 +0000
+Subject: Add configure option to reduce visual clutter at boot time
+
+If this option is enabled, then do all of the following:
+
+Don't display introductory message about line editing unless we're
+actually offering a shell prompt.  (This is believed to be a workaround
+for a different bug.  We'll go with this for now, but will drop this in
+favour of a better fix upstream if somebody figures out what that is.)
+
+Don't clear the screen just before booting if we never drew the menu in
+the first place.
+
+Remove verbose messages printed before reading configuration.  In some
+ways this is awkward because it makes debugging harder, but it's a
+requirement for a smooth-looking boot process; we may be able to do
+better in future.  Upstream doesn't want this, though.
+
+Disable the cursor as well, for similar reasons of tidiness.
+
+Suppress kernel/initrd progress messages, except in recovery mode.
+
+Suppress "GRUB loading" message unless Shift is held down.  Upstream
+doesn't want this, as it makes debugging harder.  Ubuntu wants it to
+provide a cleaner boot experience.

+Subject: minilzo: Update to minilzo-2.10
+
+minilzo fails to build on a number of Debian release architectures
+(armel, mips64el, mipsel, ppc64el) with errors such as:
+
+  ../../grub-core/lib/minilzo/minilzo.c: In function 'lzo_memops_get_le16':
+  ../../grub-core/lib/minilzo/minilzo.c:3479:11: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]

+   3530 |     LZO_MEMOPS_COPY2(&v, ss);
+        |     ^~~~~~~~~~~~~~~~
+
+The latest upstream version is 2.10, so updating to it seems like a good
+idea on general principles, and it fixes builds on all the above
+architectures.
+
+The update procedure documented in the GRUB Developers Manual worked; I
+just updated the version numbers to make it clear that it's been
+executed recently.

+Subject: Handle filesystems loop-mounted on file images
+
+Improve prepare_grub_to_access_device to emit appropriate commands for
+such filesystems, and ignore them in Linux grub.d scripts.
+
+This is needed for Ubuntu's Wubi installation method.
+
+This patch isn't inherently Debian/Ubuntu-specific.  losetup and
+/proc/mounts are Linux-specific, though, so we might need to refine this
+before sending it upstream.  The changes to the Linux grub.d scripts
+might be better handled by integrating 10_lupin properly instead.

+Subject: util/mkimage: Some fixes to PE binaries section size calculation
+
+Commit f60ba9e5945 (util/mkimage: Refactor section setup to use a helper)
+added a helper function to setup PE sections, but it caused regressions
+in some arches where the natural alignment lead to wrong section sizes.
+
+This patch fixes a few things that were caused the section sizes to be
+calculated wrongly. These fixes are:
+
+ * Only align the virtual memory addresses but not the raw data offsets.
+ * Use aligned sizes for virtual memory sizes but not for raw data sizes.
+ * Always align the sizes to set the virtual memory sizes.
+
+These seems to not cause problems for x64 and aa64 EFI platforms but was
+a problem for ia64. Because the size of the ".data" and "mods" sections
+were wrong and didn't have the correct content. Which lead to GRUB not
+being able to load any built-in module.

+Subject: fs/ntfs: Fix an OOB read when parsing a volume label
+
+This fix introduces checks to ensure that an NTFS volume label is always
+read from the corresponding file record segment.
+
+The current NTFS code allows the volume label string to be read from an
+arbitrary, attacker-chosen memory location. However, the bytes read are
+always treated as UTF-16LE. So, the final string displayed is mostly
+unreadable and it can't be easily converted back to raw bytes.
+
+The lack of this check is a minor issue, likely not causing a significant
+data leak.

+Subject: fs/ntfs: Fix an OOB read when reading data from the resident $DATA
+ attribute
+
+When reading a file containing resident data, i.e., the file data is stored in
+the $DATA attribute within the NTFS file record, not in external clusters,
+there are no checks that this resident data actually fits the corresponding
+file record segment.
+
+When parsing a specially-crafted file system image, the current NTFS code will
+read the file data from an arbitrary, attacker-chosen memory offset and of
+arbitrary, attacker-chosen length.
+
+This allows an attacker to display arbitrary chunks of memory, which could
+contain sensitive information like password hashes or even plain-text,
+obfuscated passwords from BS EFI variables.
+
+This fix implements a check to ensure that resident data is read from the
+corresponding file record segment only.

+Subject: fs/ntfs: Fix an OOB write when parsing the $ATTRIBUTE_LIST attribute
+ for the $MFT file
+
+When parsing an extremely fragmented $MFT file, i.e., the file described
+using the $ATTRIBUTE_LIST attribute, current NTFS code will reuse a buffer
+containing bytes read from the underlying drive to store sector numbers,
+which are consumed later to read data from these sectors into another buffer.
+
+These sectors numbers, two 32-bit integers, are always stored at predefined
+offsets, 0x10 and 0x14, relative to first byte of the selected entry within
+the $ATTRIBUTE_LIST attribute. Usually, this won't cause any problem.
+
+However, when parsing a specially-crafted file system image, this may cause
+the NTFS code to write these integers beyond the buffer boundary, likely
+causing the GRUB memory allocator to misbehave or fail. These integers contain
+values which are controlled by on-disk structures of the NTFS file system.
+
+Such modification and resulting misbehavior may touch a memory range not
+assigned to the GRUB and owned by firmware or another EFI application/driver.
+
+This fix introduces checks to ensure that these sector numbers are never
+written beyond the boundary.
+
+Fixes: CVE-2023-4692

+Subject: i386-pc: build verifiers API as module
+
+Given no core functions on i386-pc would require verifiers to work and
+the only consumer of the verifier API is the pgp module, it looks good
+to me that we can move the verifiers out of the kernel image and let
+moddep.lst to auto-load it when pgp is loaded on i386-pc platform.
+
+This helps to reduce the size of core image and thus can relax the
+tension of exploding on some i386-pc system with very short MBR gap
+size. See also a very comprehensive summary from Colin [1] about the
+details.
+
+[1] https://lists.gnu.org/archive/html/grub-devel/2021-03/msg00240.html
+
+V2:
+Drop COND_NOT_i386_pc and use !COND_i386_pc.
+Add comment in kern/verifiers.c to help understanding what's going on
+without digging into the commit history.

+Subject: If we don't have writable grubenv and we're on EFI, always show the
+ menu
+
+If we don't have writable grubenv, recordfail doesn't work, which means our
+quickboot behavior - with a timeout of 0 - leaves the user without a
+reliable way to access the boot menu if they're on UEFI, because unlike
+BIOS, UEFI does not support checking the state of modifier keys (i.e.
+holding down shift at boot is not detectable).
+
+Handle this corner case by always using a non-zero timeout on EFI when
+save_env doesn't work.
+
+Reuse GRUB_RECORDFAIL_TIMEOUT to avoid introducing another variable.

+Subject: Add configure option to bypass boot menu if possible
+
+If other operating systems are installed, then automatically unhide the
+menu.  Otherwise, if GRUB_HIDDEN_TIMEOUT is 0, then use keystatus if
+available to check whether Shift is pressed.  If it is, show the menu,
+otherwise boot immediately.  If keystatus is not available, then fall
+back to a short delay interruptible with Escape.
+
+This may or may not remain Ubuntu-specific, although it's not obviously
+wanted upstream.  It implements a requirement of
+https://wiki.ubuntu.com/DesktopExperienceTeam/KarmicBootExperienceDesignSpec#Bootloader.
+
+If the previous boot failed (defined as failing to get to the end of one
+of the normal runlevels), then show the boot menu regardless.

+The "ide-drive" device was removed in QEMU 6.0. The "ide-hd" has been

+Subject: Fix setup on Secure Boot systems where cryptodisk is in use
+
+On full-encrypted systems, including /boot, the current code omits
+cryptodisk commands needed to open the drives if Secure Boot is enabled.
+This prevents grub2 from reading any further configuration residing on
+the encrypted disk.
+This patch fixes this issue by adding the needed "cryptomount" commands in
+the load.cfg file that is then copied in the EFI partition.

+
+For complicated reasons, even if you have XSM/FLASK disabled (as is
+the default) the Xen build system still builds a policy file and puts
+it in /boot.
+
+Even so, we shouldn't be loading this in the usual non-"XSM enabled"

+Subject: fs/xfs: Fix unreadable filesystem with v4 superblock
+
+The commit 8b1e5d193 (fs/xfs: Add bigtime incompat feature support)
+introduced the bigtime support by adding some features in v3 inodes.
+This change extended grub_xfs_inode struct by 76 bytes but also changed
+the computation of XFS_V2_INODE_SIZE and XFS_V3_INODE_SIZE. Prior this
+commit, XFS_V2_INODE_SIZE was 100 bytes. After the commit it's 84 bytes
+XFS_V2_INODE_SIZE becomes 16 bytes too small.
+
+As a result, the data structures aren't properly aligned and the GRUB
+generates "attempt to read or write outside of partition" errors when

+
+This commit change the XFS_V2_INODE_SIZE computation by subtracting 76
+bytes instead of 92 bytes from the actual size of grub_xfs_inode struct.
+This 76 bytes value comes from added members:
+	20 grub_uint8_t   unused5
+	 1 grub_uint64_t  flags2
+        48 grub_uint8_t   unused6
+
+This patch explicitly splits the v2 and v3 parts of the structure.
+The unused4 is still ending of the v2 structures and the v3 starts
+at unused5. Thanks to this we will avoid future corruptions of v2
+or v3 inodes.
+
+The XFS_V2_INODE_SIZE is returning to its expected size and the
+filesystem is back to a readable state:

+Subject: Tell zpool to emit full device names
+
+zfs-initramfs currently provides extraneous, undesired symlinks to
+devices directly underneath /dev/ to satisfy zpool's historical output
+of unqualified device names. By including this environment variable to
+signal our intent to zpool, zfs-linux packages can drop the symlink
+behavior when updating to its upstream or backported output behavior.

+Description: GRand Unified Bootloader, version 2 (@arch@ UEFI signed by Debian)
+ GRUB is a portable, powerful bootloader.  This version of GRUB is based on a
+ cleaner design than its predecessors, and provides the following new features:
+ .
+  - Scripting in grub.cfg using BASH-like syntax.
+  - Support for modern partition maps such as GPT.
+  - Modular generation of grub.cfg via update-grub.  Packages providing GRUB
+    add-ons can plug in their own script rules and trigger updates by invoking
+    update-grub.
+ .
+ This package contains the binaries signed by the Debian UEFI CA to be used by
+ shim-signed.

+Template: grub2/force_efi_extra_removable
+Type: boolean
+Default: false
+_Description: Force extra installation to the EFI removable media path?
+ Some EFI-based systems are buggy and do not handle new bootloaders correctly.
+ If you force an extra installation of GRUB to the EFI removable media path,
+ this should ensure that this system will boot Debian correctly despite such a
+ problem. However, it may remove the ability to boot any other operating
+ systems that also depend on this path. If so, you will need to make sure that
+ GRUB is configured successfully to be able to boot any other OS installations
+ correctly.
+
+Template: grub2/update_nvram
+Type: boolean
+Default: true
+_Description: Update NVRAM variables to automatically boot into Debian?
+ GRUB can configure your platform's NVRAM variables so that it boots into
+ Debian automatically when powered on. However, you may prefer to disable
+ this behavior and avoid changes to your boot configuration. For example,
+ if your NVRAM variables have been set up such that your system contacts a
+ PXE server on every boot, this would preserve that behavior.
