	grub-install: Add backup and restore
	Refactor clean_grub_dir() to create a backup of all the files, instead
	of just irrevocably removing them as the first action. If available,
	register atexit() handler to restore the backup if errors occur before
	point of no return, or remove the backup if everything was successful.
	If atexit() is not available, the backup remains on disk for manual
	recovery.

	Some platforms defined a point of no return, i.e. after modules & core
	images were updated. Failures from any commands after that stage are
	ignored, and backup is cleaned up. For example, on EFI platforms update
	is not reverted when efibootmgr fails.

	Extra care is taken to ensure atexit() handler is only invoked by the
	parent process and not any children forks. Some older GRUB codebases
	can invoke parent atexit() hooks from forks, which can mess up the
	backup.

	This allows safer upgrades of MBR & modules, such that
	modules/images/fonts/translations are consistent with MBR in case of
	errors. For example accidental grub-install /dev/non-existent-disk
	currently clobbers and upgrades modules in /boot/grub, despite not
	actually updating any MBR.

	This patch only handles backup and restore of files copied to /boot/grub.
	This patch does not perform backup (or restoration) of MBR itself or
	blocklists. Thus when installing i386-pc platform, corruption may still
	occur with MBR and blocklists which will not be attempted to be
	automatically recovered.

	Also add modinfo.sh and *.efi to the cleanup/backup/restore code path,
	to ensure it is also cleaned, backed up and restored.

	osdep/unix/exec: Avoid atexit() handlers when child execvp() fails
	The functions grub_util_exec_pipe() and grub_util_exec_pipe_stderr()
	currently call execvp(). If the call fails for any reason, the child
	currently calls exit(127). This in turn executes the parents
	atexit() handlers from the forked child, and then the same handlers
	are called again from parent. This is usually not desired, and can
	lead to deadlocks, and undesired behavior. So, change the exit() calls
	to _exit() calls to avoid calling atexit() handlers from child.

	Fixes: e75cf4a58 (unix exec: avoid atexit handlers when child exits)

	lib/i386/relocator64: Build fixes for i386
	This fixes cross-compiling to x86 (e.g., the Hurd) from x86-linux of

	    grub-core/lib/i386/relocator64.S

	This file has six sections that only build with a 64-bit assembler,
	yet only the first two sections had support for a 32-bit assembler.
	This patch completes this for the remaining sections.

	To reproduce, update the GRUB source description in your local Guix
	archive and run

	   ./pre-inst-env guix build --system=i686-linux --target=i586-pc-gnu grub

	or install an x86 cross-build environment on x86-linux (32-bit!) and
	configure to cross build and make, e.g., do something like

	    ./configure \
	       CC_FOR_BUILD=gcc \
	       --build=i686-unknown-linux-gnu \
	       --host=i586-pc-gnu
	    make

	Additionally, remove a line with redundant spaces.

	fs/xfs: Add needsrepair incompat feature support
	The XFS now has an incompat feature flag to indicate that a filesystem
	needs to be repaired. The Linux kernel refuses to mount the filesystem
	that has it set and only the xfs_repair tool is able to clear that flag.

	The GRUB doesn't have the concept of mounting filesystems and just
	attempts to read the files. But it does some sanity checking before
	attempting to read from the filesystem. Among the things which are tested,
	is if the super block only has set of incompatible features flags that
	are supported by GRUB. If it contains any flags that are not listed as
	supported, reading the XFS filesystem fails.

	Since the GRUB doesn't attempt to detect if the filesystem is inconsistent
	nor replays the journal, the filesystem access is a best effort. For this
	reason, ignore if the filesystem needs to be repaired and just print a debug
	message. That way, if reading or booting fails later, the user is able to
	figure out that the failures can be related to broken XFS filesystem.

	fs/xfs: Add bigtime incompat feature support
	The XFS filesystem supports a bigtime feature to overcome y2038 problem.
	This patch makes the GRUB able to support the XFS filesystems with this
	feature enabled.

	The XFS counter for the bigtime enabled timestamps starts at 0, which
	translates to GRUB_INT32_MIN (Dec 31 20:45:52 UTC 1901) in the legacy
	timestamps. The conversion to Unix timestamps is made before passing the
	value to other GRUB functions.

	For this to work properly, GRUB requires an access to flags2 field in the
	XFS ondisk inode. So, the grub_xfs_inode structure has been updated to
	cover full ondisk inode.

	fs: Use 64-bit type for filesystem timestamp
	Some filesystems nowadays use 64-bit types for timestamps. So, update
	grub_dirhook_info struct to use an grub_int64_t type to store mtime.
	This also updates the grub_unixtime2datetime() function to receive
	a 64-bit timestamp argument and do 64-bit-safe divisions.

	All the remaining conversion from 32-bit to 64-bit should be safe, as
	32-bit to 64-bit attributions will be implicitly casted. The most
	critical part in the 32-bit to 64-bit conversion is in the function
	grub_unixtime2datetime() where it needs to deal with the 64-bit type.
	So, for that, the grub_divmod64() helper has been used.

	These changes enables the GRUB to support dates beyond y2038.

	util/mkimage: Fix wrong PE32+ section sizes for some arches
	The commit f60ba9e5945 (util/mkimage: Refactor section setup to use a helper)
	added a helper function to setup PE sections. But it also changed how the
	raw data offsets were calculated since all the section sizes are aligned.
	However, for some platforms, i.e ia64-efi and arm64-efi, the kernel image
	size is not aligned using the section alignment. This leads to the situation
	in which the mods section offset in its PE section header does not match its
	real placement in the PE file. So, finally the GRUB is not able to locate
	and load built-in modules.

	The problem surfaces on ia64-efi and arm64-efi because both platforms
	require additional relocation data which is added behind .bss section.
	So, we have to add some padding behind this extra data to make the
	beginning of mods section properly aligned in the PE file. Fix it by
	aligning the kernel_size to the section alignment. That makes the sizes
	and offsets in the PE section headers to match relevant sections in the
	PE32+ binary file.

	i18n: Format large integers before the translation message
	The GNU gettext only supports the ISO C99 macros for integral
	types. If there is a need to use unsupported formatting macros,
	e.g. PRIuGRUB_UINT64_T, according to [1] the number to a string
	conversion should be separated from the code printing message
	requiring the internationalization. So, the function grub_snprintf()
	is used to print the numeric values to an intermediate buffer and
	the internationalized message contains a string format directive.

	video/fb/fbfill: Use unsigned integers for width/height
	Since commit 7ce3259f67ac (video/fb/fbfill: Fix potential integer
	overflow), clang builds of grub-emu have failed with messages like:

	  /usr/bin/ld: libgrubmods.a(libgrubmods_a-fbfill.o): in function `grub_video_fbfill_direct24':
	  fbfill.c:(.text+0x28e): undefined reference to `__muloti4'

	This appears to be due to a weird quirk in how clang compiles

	  grub_mul(dst->mode_info->bytes_per_pixel, width, &rowskip)

	which is grub_mul(unsigned int, int, &grub_size_t).

	It looks like clang somewhere promotes everything to 128-bit maths
	before ultimately reducing down to 64 bit for grub_size_t. I think
	this is because width is signed, and indeed converting width to an
	unsigned int makes the problem go away.

	This conversion also makes more sense generally:
	  - the caller of all the fbfill_directN functions is
	    grub_video_fb_fill_dispatch() and it takes width and height as
	    unsigned ints already,
	  - it doesn't make sense to fill a negative width or height.

	Convert the width and height arguments and associated loop counters
	to unsigned ints.

	fs/minix: Avoid mistakenly probing ext2 filesystems
	The ext2 (and ext3, ext4) filesystems write the number of free inodes to
	location 0x410.

	On a MINIX filesystem, that same location is used for the MINIX superblock
	magic number.

	If the number of free inodes on an ext2 filesystem is equal to any
	of the four MINIX superblock magic values plus any multiple of 65536,
	GRUB's MINIX filesystem code will probe it as a MINIX filesystem.

	In the case of an OS using ext2 as the root filesystem, since there will
	ordinarily be some amount of file creation and deletion on every bootup,
	it effectively means that this situation has a 1:16384 chance of being hit
	on every reboot.

	This will cause GRUB's filesystem probing code to mistakenly identify an
	ext2 filesystem as MINIX. This can be seen by e.g. "search --label"
	incorrectly indicating that no such ext2 partition with matching label
	exists, whereas in fact it does.

	After spotting the rough cause of the issue I was facing here, I borrowed
	much of the diagnosis/explanation from meierfra who found and investigated
	the same issue in util-linux in 2010:

	  https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/518582

	This was fixed in util-linux by having the MINIX code check for the
	ext2 magic. Do the same here.

	This patch does the following:
	 - really disables os-prober by default in the util/grub-mkconfig.in

	 - fixes the logic in the util/grub.d/30_os-prober.in,

	  The default was GRUB_DISABLE_OS_PROBER=false if you don't set
	  GRUB_DISABLE_OS_PROBER at all. To prevent os-prober from starting we
	  have to set it by default to true and shuffle GRUB_DISABLE_OS_PROBER to

	The chainloaded PE image could also have trusted signature created by

	disk/pata: Suppress error message "no device connected"
	This error message comes from the grub_print_error() in
	grub_pata_device_initialize(), which does not pass on the error, and is
	raised in check_device(). The function check_device() needs to return this
	as an error because check_device() is also used in grub_pata_open(), which
	does pass on this error to indicate that the device can not be used.

	This is actually not an error when displayed by grub_pata_device_initialize()
	because it just indicates that there are no pata devices seen. This may be
	confusing to end users who do not have pata devices yet are loading the
	pata module (perhaps implicitly via nativedisk). This also causes unnecessary
	output which may need to be accounted for in functional testing.

	Instead print to the debug log when check_device() raises this "error" and
	pop the error from the error stack. If there is another error on the stack
	then print the error stack as those should be real errors.

	fs/ext2: Fix a file not found error when a symlink filesize is equal to 60
	We encountered a file not found error when the symlink filesize is

	  lrwxrwxrwx 1 root root 60 Jan  6 16:37 initrd -> secure-core-image-initramfs-5.10.2-yoctodev-standard.cpio.gz

	When booting, we got the following error in the GRUB:

	  error: file `/initrd' not found

	The root cause is that the size of diro->inode.symlink is equal to 60
	and a symlink name has to be terminated with NUL there. So, if the
	symlink filesize is exactly 60 then it is also stored in a separate
	block rather than in the inode itself.

	kern/misc: Add function to check printf() format against expected format
	The grub_printf_fmt_check() function parses the arguments of an untrusted
	printf() format and an expected printf() format and then compares the
	arguments counts and arguments types. The arguments count in the untrusted
	format string must be less or equal to the arguments count in the expected
	format string and both arguments types must match.

	To do this the parse_printf_arg_fmt() helper function is extended in the
	following way:

	  1. Add a return value to report errors to the grub_printf_fmt_check().

	  2. Add the fmt_check argument to enable stricter format verification:
	     - the function expects that arguments definitions are always
	       terminated by a supported conversion specifier.
	     - positional parameters, "$", are not allowed, as they cannot be
	       validated correctly with the current implementation. For example
	       "%s%1$d" would assign the first args entry twice while leaving the
	       second one unchanged.
	     - Return an error if preallocated space in args is too small and
	       allocation fails for the needed size. The grub_printf_fmt_check()
	       should verify all arguments. So, if validation is not possible for
	       any reason it should return an error.
	     This also adds a case entry to handle "%%", which is the escape
	     sequence to print "%" character.

	  3. Add the max_args argument to check for the maximum allowed arguments
	     count in a printf() string. This should be set to the arguments count
	     of the expected format. Then the parse_printf_arg_fmt() function will
	     return an error if the arguments count is exceeded.

	The two additional arguments allow us to use parse_printf_arg_fmt() in
	printf() and grub_printf_fmt_check() calls.

	When parse_printf_arg_fmt() is used by grub_printf_fmt_check() the
	function parse user provided untrusted format string too. So, in
	that case it is better to be too strict than too lenient.

	Set printf() argument type for "%s" to new type STRING. This is in
	preparation for a follow up patch to compare a printf() format string
	against an expected printf() format string.

	For "%s" the corresponding printf() argument is dereferenced as pointer
	while all other argument types are defined as integer value. However,

	from "%p" and other integers. So, let's do that.

	This happens when the process of reading the catalog file goes sufficiently
	wrong that there's an attempt to read the extent overflow file, which has
	not yet been loaded. Keep track of when the extent overflow file is
	fully loaded and refuse to use it before then.

	The load valgrind doesn't like is btree->nodesize, and that's then used
	to allocate a data structure. It looks like there are subsequently a lot
	of reads based on that pointer so OOB reads are likely, and indeed crashes
	(albeit difficult-to-replicate ones) have been observed in fuzzing.

	fs/fshelp: Catch impermissibly large block sizes in read helper
	A fuzzed HFS+ filesystem had log2blocksize = 22. This gave

	In the while(1) the correct exit mechanism should not be to do a direct return,

	The reason behind this is that the dnode_path is a linked list, and while doing

	correctly unravel it is to traverse it, which is what is being done at the end

	kern/efi/mm: Fix possible NULL pointer dereference
	The model of grub_efi_get_memory_map() is that if memory_map is NULL,
	then the purpose is to discover how much memory should be allocated to
	it for the subsequent call.

	The problem here is that with grub_efi_is_finished set to 1, there is no
	check at all that the function is being called with a non-NULL memory_map.

	While this MAY be true, we shouldn't assume it.

	The solution to this is to behave as expected, and if memory_map is NULL,
	then don't try to use it and allow memory_map_size to be filled in, and
	return 0 as is done later in the code if the buffer is too small (or NULL).

	Additionally, drop unneeded ret = 1.

	kern: Add lockdown support
	When the GRUB starts on a secure boot platform, some commands can be
	used to subvert the protections provided by the verification mechanism and
	could lead to booting untrusted system.

	To prevent that situation, allow GRUB to be locked down. That way the code
	may check if GRUB has been locked down and further restrict the commands
	that are registered or what subset of their functionality could be used.

	The lockdown support adds the following components:

	* The grub_lockdown() function which can be used to lockdown GRUB if,
	  e.g., UEFI Secure Boot is enabled.

	* The grub_is_lockdown() function which can be used to check if the GRUB
	  was locked down.

	* A verifier that flags OS kernels, the GRUB modules, Device Trees and ACPI
	  tables as GRUB_VERIFY_FLAGS_DEFER_AUTH to defer verification to other
	  verifiers. These files are only successfully verified if another registered
	  verifier returns success. Otherwise, the whole verification process fails.

	  For example, PE/COFF binaries verification can be done by the shim_lock
	  verifier which validates the signatures using the shim_lock protocol.
	  However, the verification is not deferred directly to the shim_lock verifier.
	  The shim_lock verifier is hooked into the verification process instead.

	* A set of grub_{command,extcmd}_lockdown functions that can be used by
	  code registering command handlers, to only register unsafe commands if
	  the GRUB has not been locked down.

2020-12-12  Glenn Washburn  <development@efficientek.com>

	cryptodisk: Properly handle non-512 byte sized sectors
	By default, dm-crypt internally uses an IV that corresponds to 512-byte
	sectors, even when a larger sector size is specified. What this means is
	that when using a larger sector size, the IV is incremented every sector.
	However, the amount the IV is incremented is the number of 512 byte blocks
	in a sector (i.e. 8 for 4K sectors). Confusingly the IV does not correspond
	to the number of, for example, 4K sectors. So each 512 byte cipher block in
	a sector will be encrypted with the same IV and the IV will be incremented
	afterwards by the number of 512 byte cipher blocks in the sector.

	There are some encryption utilities which do it the intuitive way and have
	the IV equal to the sector number regardless of sector size (ie. the fifth
	sector would have an IV of 4 for each cipher block). And this is supported
	by dm-crypt with the iv_large_sectors option and also cryptsetup as of 2.3.3
	with the --iv-large-sectors, though not with LUKS headers (only with --type
	plain). However, support for this has not been included as grub does not
	support plain devices right now.

	One gotcha here is that the encrypted split keys are encrypted with a hard-
	coded 512-byte sector size. So even if your data is encrypted with 4K sector
	sizes, the split key encrypted area must be decrypted with a block size of
	512 (ie the IV increments every 512 bytes). This made these changes less
	aesthetically pleasing than desired.

	efi: Only register shim_lock verifier if shim_lock protocol is found and SB enabled
	The shim_lock module registers a verifier to call shim's verify, but the
	handler is registered even when the shim_lock protocol was not installed.

	This doesn't cause a NULL pointer dereference in shim_lock_write() because
	the shim_lock_init() function just returns GRUB_ERR_NONE if sl isn't set.

	But in that case there's no point to even register the shim_lock verifier
	since won't do anything. Additionally, it is only useful when Secure Boot
	is enabled.

	Finally, don't assume that the shim_lock protocol will always be present
	when the shim_lock_write() function is called, and check for it on every
	call to this function.

	tftp: Roll-over block counter to prevent data packets timeouts
	Commit 781b3e5efc3 (tftp: Do not use priority queue) caused a regression
	when fetching files over TFTP whose size is bigger than 65535 * block size.

	  grub> linux /images/pxeboot/vmlinuz
	  grub> echo $?
	  0
	  grub> initrd /images/pxeboot/initrd.img
	  error: timeout reading '/images/pxeboot/initrd.img'.
	  grub> echo $?
	  28

	It is caused by the block number counter being a 16-bit field, which leads
	to a maximum file size of ((1 << 16) - 1) * block size. Because GRUB sets
	the block size to 1024 octets (by using the TFTP Blocksize Option from RFC
	2348 [0]), the maximum file size that can be transferred is 67107840 bytes.

	The TFTP PROTOCOL (REVISION 2) RFC 1350 [1] does not mention what a client
	should do when a file size is bigger than the maximum, but most TFTP hosts
	support the block number counter to be rolled over. That is, acking a data
	packet with a block number of 0 is taken as if the 65356th block was acked.

	It was working before because the block counter roll-over was happening due
	an overflow. But that got fixed by the mentioned commit, which led to the
	regression when attempting to fetch files larger than the maximum size.

	To allow TFTP file transfers of unlimited size again, re-introduce a block
	counter roll-over so the data packets are acked preventing the timeouts.

	luks: Fix out-of-bounds copy of UUID

	we mistakenly use the size of the grub_cryptodisk_t UUID field, which
	is guaranteed to be strictly bigger than the LUKS UUID field we're
	copying. As a result, the copy always goes out-of-bounds and copies some
	garbage from other surrounding fields. During runtime, this isn't
	noticed due to the fact that we always NUL-terminate the UUID and thus
	never hit the trailing garbage.

	Fix the issue by using the size of the local stripped UUID field.

	efi: Fix some malformed device path arithmetic errors
	Several places we take the length of a device path and subtract 4 from
	it, without ever checking that it's >= 4. There are also cases where
	this kind of malformation will result in unpredictable iteration,
	including treating the length from one dp node as the type in the next
	node. These are all errors, no matter where the data comes from.

	This patch adds a checking macro, GRUB_EFI_DEVICE_PATH_VALID(), which
	can be used in several places, and makes GRUB_EFI_NEXT_DEVICE_PATH()
	return NULL and GRUB_EFI_END_ENTIRE_DEVICE_PATH() evaluate as true when
	the length is too small. Additionally, it makes several places in the

	tftp: Do not use priority queue
	There is not need to reassemble the order of blocks. Per RFC 1350,
	server must wait for the ACK, before sending next block. Data packets
	can be served immediately without putting them to priority queue.

	Logic to handle incoming packet is this:
	  - if packet block id equal to expected block id, then
	    process the packet,
	  - if packet block id is less than expected - this is retransmit
	    of old packet, then ACK it and drop the packet,
	  - if packet block id is more than expected - that shouldn't
	    happen, just drop the packet.

	It makes the tftp receive path code simpler, smaller and faster.
	As a benefit, this change fixes CID# 73624 and CID# 96690, caused
	by following while loop:

	  while (cmp_block (grub_be_to_cpu16 (tftph->u.data.block), data->block + 1) == 0)

	where tftph pointer is not moving from one iteration to another, causing
	to serve same packet again. Luckily, double serving didn't happen due to

	yylex: Make lexer fatal errors actually be fatal
	When presented with a command that can't be tokenized to anything
	smaller than YYLMAX characters, the parser calls YY_FATAL_ERROR(errmsg),
	expecting that will stop further processing, as such:

	  #define YY_DO_BEFORE_ACTION \
	        yyg->yytext_ptr = yy_bp; \
	        yyleng = (int) (yy_cp - yy_bp); \
	        yyg->yy_hold_char = *yy_cp; \
	        *yy_cp = '\0'; \
	        if ( yyleng >= YYLMAX ) \
	                YY_FATAL_ERROR( "token too large, exceeds YYLMAX" ); \
	        yy_flex_strncpy( yytext, yyg->yytext_ptr, yyleng + 1 , yyscanner); \
	        yyg->yy_c_buf_p = yy_cp;

	The code flex generates expects that YY_FATAL_ERROR() will either return
	for it or do some form of longjmp(), or handle the error in some way at
	least, and so the strncpy() call isn't in an "else" clause, and thus if
	YY_FATAL_ERROR() is *not* actually fatal, it does the call with the
	questionable limit, and predictable results ensue.

	Unfortunately, our implementation of YY_FATAL_ERROR() is:

	   #define YY_FATAL_ERROR(msg)                     \
	     do {                                          \
	       grub_printf (_("fatal error: %s\n"), _(msg));     \
	     } while (0)

	The same pattern exists in yyless(), and similar problems exist in users
	of YY_INPUT(), several places in the main parsing loop,
	yy_get_next_buffer(), yy_load_buffer_state(), yyensure_buffer_stack,
	yy_scan_buffer(), etc.

	All of these callers expect YY_FATAL_ERROR() to actually be fatal, and
	the things they do if it returns after calling it are wildly unsafe.

	(indicating that some of the cache maintenance operations can be
	removed when dealing with I/D-cache coherency, GRUB dies with a
	"Unsupported cache type 0x........" message.

	This is pretty likely to happen when running in a virtual machine
	hosted on an arm64 machine (I've triggered it on a system built around

	It turns out that the way GRUB deals with the CTR register is a bit
	harsh for anything from ARMv7 onwards. The layout of the register is
	backward compatible, meaning that nothing that gets added is allowed to
	break earlier behaviour. In this case, ignoring IDC is completely fine,

	We can thus avoid being paranoid, and align the 32bit behaviour with

	This is useful for users since the hotkey to enter into the EFI setup menu

	kern/term: Accept ESC, F4 and holding SHIFT as user interrupt keys
	On some devices the ESC key is the hotkey to enter the BIOS/EFI setup
	screen, making it really hard to time pressing it right. Besides that
	ESC is also pretty hard to discover for a user who does not know it
	will unhide the menu.

	This commit makes F4, which was chosen because is not used as a hotkey
	to enter the BIOS setup by any vendor, also interrupt sleeps / stop the
	menu countdown.

	This solves the ESC gets into the BIOS setup and also somewhat solves
	the discoverability issue, but leaves the timing issue unresolved.

	This commit fixes the timing issue by also adding support for keeping
	SHIFT pressed during boot to stop the menu countdown. This matches

	This is needed because the logic to determine if a key was pressed to make

	account the SHIFT key being held down.

	For this reason the EFI console driver has to support getkeystatus() to
	allow detecting that event.

	Note that if a non-modifier key gets pressed and repeated calls to
	getkeystatus() are made then it will return the modifier status at the
	time of the non-modifier key, until that key-press gets consumed by a

	efi/console: Add grub_console_read_key_stroke() helper function
	This is a preparatory patch for adding getkeystatus() support to the
	EFI console driver.

	We can get modifier status through the simple_text_input read_key_stroke()
	method, but if a non-modifier key is (also) pressed the read_key_stroke()
	call will consume that key from the firmware's queue.

	The new grub_console_read_key_stroke() helper buffers upto 1 key-stroke.
	If it has a non-modifier key buffered, it will return that one, if its
	buffer is empty, it will fills its buffer by getting a new key-stroke.

	If called with consume=1 it will empty its buffer after copying the
	key-data to the callers buffer, this is how getkey() will use it.

	If called with consume=0 it will keep the last key-stroke buffered, this
	is how getkeystatus() will call it. This means that if a non-modifier
	key gets pressed, repeated getkeystatus() calls will return the modifiers
	of that key-press until it is consumed by a getkey() call.

	Here I'd like to quote from the gcc document [1] which seems best to
	explain what is going on here.

	"Although the size of a zero-length array is zero, an array member of
	this kind may increase the size of the enclosing type as a result of
	tail padding. The offset of a zero-length array member from the
	beginning of the enclosing structure is the same as the offset of an
	array with one or more elements of the same type. The alignment of a
	zero-length array is the same as the alignment of its elements.

	Declaring zero-length arrays in other contexts, including as interior
	members of structure objects or as non-member objects, is discouraged.
	Accessing elements of zero-length arrays declared in such contexts is
	undefined and may be diagnosed."

	The l_hash[0] is apparnetly an interior member to the enclosed structure
	while l_entries[0] is the trailing member. And the offending code tries
	to access members in l_hash[0] array that triggers the diagnose.

	Given that the l_entries[0] is used to get proper alignment to access
	leaf chunks, we can accomplish the same thing through the ALIGN_UP macro
	thus eliminating l_entries[0] from the structure. In this way we can
	pacify the warning as l_hash[0] now becomes the last member to the
	enclosed structure.

	lvm: Add LVM cache logical volume handling
	The LVM cache logical volume is the logical volume consisting of the original
	and the cache pool logical volume. The original is usually on a larger and
	slower storage device while the cache pool is on a smaller and faster one. The
	performance of the original volume can be improved by storing the frequently
	used data on the cache pool to utilize the greater performance of faster
	device.

	The default cache mode "writethrough" ensures that any data written will be
	stored both in the cache and on the origin LV, therefore grub can be straight
	to read the original lv as no data loss is guarenteed.

	The second cache mode is "writeback", which delays writing from the cache pool
	back to the origin LV to have increased performance. The drawback is potential
	data loss if losing the associated cache device.

	During the boot time grub reads the LVM offline i.e. LVM volumes are not
	activated and mounted, hence it should be fine to read directly from original
	lv since all cached data should have been flushed back in the process of taking
	it offline.

	It is also not much helpful to the situation by adding fsync calls to the
	install code. The fsync did not force to write back dirty cache to the original
	device and rather it would update associated cache metadata to complete the
	write transaction with the cache device. IOW the writes to cached blocks still
	go only to the cache device.

	To write back dirty cache, as LVM cache did not support dirty cache flush per
	block range, there'no way to do it for file. On the other hand the "cleaner"
	policy is implemented and can be used to write back "all" dirty blocks in a
	cache, which effectively drain all dirty cache gradually to attain and last in
	the "clean" state, which can be useful for shrinking or decommissioning a
	cache. The result and effect is not what we are looking for here.

	In conclusion, as it seems no way to enforce file writes to the original
	device, grub may suffer from power failure as it cannot assemble the cache
	device and read the dirty data from it. However since the case is only
	applicable to writeback mode which is sensitive to data lost in nature, I'd
	still like to propose my (relatively simple) patch and treat reading dirty
	cache as improvement.

	When building GRUB with memory management debugging enabled, then the

	"base64.h" to unconditionaly include "config-util.h", which shouldn't be

	error.

	Fix the issue by removing the <config-util.h> include altogether. The

	build: Fix option to explicitly disable memory debugging
	The memory management system supports a debug mode that can be enabled
	at build time by passing "--enable-mm-debug" to the configure script.
	Passing the option will cause us define MM_DEBUG as expected, but in
	fact the reverse option "--disable-mm-debug" will do the exact same
	thing and also set up the define. This currently causes the build of
	"lib/gnulib/base64.c" to fail as it tries to use `grub_debug_malloc()`
	and `grub_debug_free()` even though both symbols aren't defined.

	Seemingly, `AC_ARG_ENABLE()` will always execute the third argument if
	either the positive or negative option was passed. Let's thus fix the
	issue by moving the call to`AC_DEFINE()` into an explicit `if test
	$xenable_mm_debug` block, similar to how other defines work.

	efi: Fix the type of grub_efi_status_t
	Currently, in some builds with some checkers, we see:

	1. grub-core/disk/efi/efidisk.c:601: error[shiftTooManyBitsSigned]: Shifting signed 64-bit value by 63 bits is undefined behaviour

	This is because grub_efi_status_t is defined as grub_efi_intn_t, which is
	signed, and shifting into the sign bit is not defined behavior.  UEFI fixed
	this in the spec in 2.3:

	2.3 | Change the defined type of EFI_STATUS from INTN to UINTN | May 7, 2009

	And the current EDK2 code has:
	MdePkg/Include/Base.h-//
	MdePkg/Include/Base.h-// Status codes common to all execution phases
	MdePkg/Include/Base.h-//

	efi/gop: Add support for BLT_ONLY adapters
	EFI GOP has support for multiple different bitness types of frame buffers
	and for a special "BLT only" type which is always defined to be RGBx.

	Because grub2 doesn't ever directly access the frame buffer but instead
	only renders graphics via the BLT interface anyway, we can easily support
	these adapters.

	The reason this has come up now is the emerging support for virtio-gpu
	in OVMF. That adapter does not have the notion of a memory mapped frame
	buffer and thus is BLT only.

	  Reason: The character that terminates the directive number 3 is not a valid conversion specifier.

	This was caused by "%m" being replaced with foreign Unicode characters.

	  msgstr "ﺹﺎﻨﻧﻮﺗ ﺮﻌﻧﺎﻤﻋ ﺖﻬﻋ ﻒִﻴﻠﻋ %s ﺕﻭ %s: %ﻡ"

	misc: Make grub_strtol() "end" pointers have safer const qualifiers
	Currently the string functions grub_strtol(), grub_strtoul(), and
	grub_strtoull() don't declare the "end" pointer in such a way as to
	require the pointer itself or the character array to be immutable to the
	implementation, nor does the C standard do so in its similar functions,
	though it does require us not to change any of it.

	The typical declarations of these functions follow this pattern:

	long
	strtol(const char * restrict nptr, char ** restrict endptr, int base);

	Much of the reason for this is historic, and a discussion of that
	follows below, after the explanation of this change.  (GRUB currently
	does not include the "restrict" qualifiers, and we name the arguments a
	bit differently.)

	The implementation is semantically required to treat the character array
	as immutable, but such accidental modifications aren't stopped by the
	compiler, and the semantics for both the callers and the implementation
	of these functions are sometimes also helped by adding that requirement.

	This patch changes these declarations to follow this pattern instead:

	long
	strtol(const char * restrict nptr,
	       const char ** const restrict endptr,
	       int base);

	This means that if any modification to these functions accidentally
	introduces either an errant modification to the underlying character
	array, or an accidental assignment to endptr rather than *endptr, the
	compiler should generate an error.  (The two uses of "restrict" in this
	case basically mean strtol() isn't allowed to modify the character array
	by going through *endptr, and endptr isn't allowed to point inside the
	array.)

	It also means the typical use case changes to:

	  char *s = ...;
	  const char *end;
	  long l;

	  l = strtol(s, &end, 10);

	Or even:

	  const char *p = str;
	  while (p && *p) {
		  long l = strtol(p, &p, 10);
		  ...
	  }

	This fixes 26 places where we discard our attempts at treating the data
	safely by doing:

	  const char *p = str;
	  long l;

	  l = strtol(p, (char **)&ptr, 10);

	It also adds 5 places where we do:

	  char *p = str;
	  while (p && *p) {
		  long l = strtol(p, (const char ** const)&p, 10);
		  ...
		  /* more calls that need p not to be pointer-to-const */
	  }

	While moderately distasteful, this is a better problem to have.

	With one minor exception, I have tested that all of this compiles
	without relevant warnings or errors, and that /much/ of it behaves
	correctly, with gcc 9 using 'gcc -W -Wall -Wextra'.  The one exception
	is the changes in grub-core/osdep/aros/hostdisk.c , which I have no idea
	how to build.

	Because the C standard defined type-qualifiers in a way that can be
	confusing, in the past there's been a slow but fairly regular stream of
	churn within our patches, which add and remove the const qualifier in many
	of the users of these functions.  This change should help avoid that in
	the future, and in order to help ensure this, I've added an explanation
	in misc.h so that when someone does get a compiler warning about a type
	error, they have the fix at hand.

	The reason we don't have "const" in these calls in the standard is
	purely anachronistic: C78 (de facto) did not have type qualifiers in the
	syntax, and the "const" type qualifier was added for C89 (I think; it
	may have been later).  strtol() appears to date from 4.3BSD in 1986,
	which means it could not be added to those functions in the standard
	without breaking compatibility, which is usually avoided.

	The syntax chosen for type qualifiers is what has led to the churn
	regarding usage of const, and is especially confusing on string
	functions due to the lack of a string type.  Quoting from C99, the
	syntax is:

	 declarator:
	  pointer[opt] direct-declarator
	 direct-declarator:
	  identifier
	  ( declarator )
	  direct-declarator [ type-qualifier-list[opt] assignment-expression[opt] ]
	  ...
	  direct-declarator [ type-qualifier-list[opt] * ]
	  ...
	 pointer:
	  * type-qualifier-list[opt]
	  * type-qualifier-list[opt] pointer
	 type-qualifier-list:
	  type-qualifier
	  type-qualifier-list type-qualifier
	 ...
	 type-qualifier:
	  const
	  restrict
	  volatile

	So the examples go like:

	const char foo;			// immutable object
	const char *foo;		// mutable pointer to object
	char * const foo;		// immutable pointer to mutable object
	const char * const foo;		// immutable pointer to immutable object
	const char const * const foo; 	// XXX extra const keyword in the middle
	const char * const * const foo; // immutable pointer to immutable
					//   pointer to immutable object
	const char ** const foo;	// immutable pointer to mutable pointer
					//   to immutable object

	Making const left-associative for * and right-associative for everything
	else may not have been the best choice ever, but here we are, and the
	inevitable result is people using trying to use const (as they should!),
	putting it at the wrong place, fighting with the compiler for a bit, and
	then either removing it or typecasting something in a bad way.  I won't
	go into describing restrict, but its syntax has exactly the same issue
	as with const.

	Anyway, the last example above actually represents the *behavior* that's
	required of strtol()-like functions, so that's our choice for the "end"
	pointer.

	grub-editenv: Make grub-editenv chase symlinks including those across devices
	The grub-editenv create command will wrongly overwrite /boot/grub2/grubenv
	with a regular file if grubenv is a symbolic link. But instead, it should
	create a new file in the path the symlink points to.

	This lets /boot/grub2/grubenv be a symlink to /boot/efi/EFI/fedora/grubenv
	even when they're different mount points, which allows grub2-editenv to be
	the same across platforms (i.e. UEFI vs BIOS).

	For example, in Fedora the GRUB EFI builds have prefix set to /EFI/fedora
	(on the EFI System Partition), but for BIOS machine it'll be /boot/grub2
	(which may or may not be its own mountpoint).

	With this patch, on EFI machines we can make /boot/grub2/grubenv a symlink
	to /boot/efi/EFI/fedora/grubenv, and the same copy of grub-set-default will
	work on both kinds of systems.

	Windows doesn't implement a readlink primitive, so the current behaviour is
	maintained for this operating system.

	grub-editenv: Add grub_util_readlink()
	Currently grub-editenv and related tools are not able to follow symbolic
	links when finding their config file. For example the grub-editenv create
	command will wrongly overwrite a symlink in /boot/grub2/grubenv with a new
	regular file, instead of creating a file in the path the symlink points to.

	A following patch will change that and add support in grub-editenv to
	follow symbolic links when finding the grub environment variables file.

	Add a grub_util_readlink() helper function that is just a wrapper around
	the platform specific function to read the value of a symbolic link. This
	helper function will be used by the following patch for grub-editenv.

	The helper function is not added for Windows, since this operating system

	normal: Move common datetime functions out of the normal module
	The common datetime helper functions are currently included in the normal
	module, but this makes any other module that calls these functions to have
	a dependency with the normal module only for this reason.

	Since the normal module does a lot of stuff, it calls functions from other
	modules. But since other modules may depend on it for calling the datetime
	helpers, this could lead to circular dependencies between modules.

	As an example, when platform == xen the grub_get_datetime() function from
	the datetime module calls to the grub_unixtime2datetime() helper function
	from the normal module. Which leads to the following module dependency:

	    datetime -> normal

	and send_dhcp_packet() from the net module calls the grub_get_datetime()
	function, which leads to the following module dependency:

	    net -> datetime -> normal

	but that means that the normal module is not allowed to depend on net or
	any other module that depends on it due the transitive dependency caused
	by datetime. A recent patch attempted to add support to fetch the config
	file over the network, which leads to the following circular dependency:

	    normal -> net -> datetime -> normal

	So having the datetime helpers in the normal module makes it quite fragile
	and easy to add circular dependencies like these, that break the build due
	the genmoddep.awk script catching the issues.

	Fix this by taking the datetime helper functions out of the normal module
	and instead add them to the datetime module itself. Besides fixing these
	issues, it makes more sense to have these helper functions there anyways.

	freedos: Fix FreeDOS command booting large files (near or above 64 KiB)
	While testing the 86-DOS lDebug [1] booting from GRUB2, newer versions of the
	debugger would fail to load when booted using GRUB's freedos command. The
	behaviour observed in a qemu i386 machine was that the ROM-BIOS's boot load
	would start anew, instead of loading the selected debugger as kernel.

	It came to light that there was a size limit: Kernel files that were 58880
	bytes (E600h) long or shorter succeeded to boot, while files that were 64000
	bytes or longer failed in the manner described.

	Eventually it turned out that the relocator16 stub succeeded whenever it was
	placed completely within the first 64 KiB of the Low Memory Area. The chunk
	for the relocator is allocated with a minimum address of 0x8010 and a maximum
	address just below 0xA0000 [2]. That means if the kernel is, for instance,
	E600h bytes long, then the kernel will be allocated memory starting at 00600h
	(the fixed FreeDOS kernel load address) up to E600h + 00600h = 0EC00h, which
	leaves 1400h (5120) bytes for the relocator to stay in the first 64 KiB.
	If the kernel is 64000 bytes (FA00h) long, then the relocator must go to
	FA00h + 00600h = 10000h at least which is outside the first 64 KiB.

	The problem is that the relocator16 initialises the DS register with a
	"pseudo real mode" descriptor, which is defined with a segment limit of
	64 KiB and a segment base of zero. After that, the relocator addressed
	parts of itself (implicitly) using the DS register, with an offset from
	ESI, which holds the linear address of the relocator's base [3]. With the
	larger kernel files this would lead to accessing data beyond the 64 KiB
	segment limit, presumably leading to a fault and perhaps a subsequent
	triple-fault or such.

	This patch fixes the relocator to set the segment base of the descriptors
	to the base address of the relocator; then, the subsequent accesses to
	the relocator's variables are done without the ESI register as an index.
	This does not interfere with the relocator's or its target's normal
	operation; the segment limits are still loaded with 64 KiB and all the
	segment bases are subsequently reset by the relocator anyway.

	Current versions of the debugger to test are uploaded to [4]. The file
	ldebugnh.com (LZ4-compressed and built with -D_EXTHELP=0) at 58368 bytes
	loads successfully, whereas ldebug.com at 64000 bytes fails. Loading one
	of these files requires setting root to a FAT FS partition and using the
	freedos command to specify the file as kernel:

	set root='(hd0,msdos1)'
	freedos /ldebug.com
	boot

	Booting the file using the multiboot command (which uses a WIP entrypoint
	of the debugger) works, as it does not use GRUB's relocator16 but instead
	includes a loader in the kernel itself, which drops it back to 86 Mode.

	disk: Implement support for LUKS2
	With cryptsetup 2.0, a new version of LUKS was introduced that breaks
	compatibility with the previous version due to various reasons. GRUB
	currently lacks any support for LUKS2, making it impossible to decrypt
	disks encrypted with that version. This commit implements support for
	this new format.

	Note that LUKS1 and LUKS2 are quite different data formats. While they
	do share the same disk signature in the first few bytes, representation
	of encryption parameters is completely different between both versions.
	While the former version one relied on a single binary header, only,
	LUKS2 uses the binary header only in order to locate the actual metadata
	which is encoded in JSON. Furthermore, the new data format is a lot more
	complex to allow for more flexible setups, like e.g. having multiple
	encrypted segments and other features that weren't previously possible.
	Because of this, it was decided that it doesn't make sense to keep both
	LUKS1 and LUKS2 support in the same module and instead to implement it
	in two different modules luks and luks2.

	The proposed support for LUKS2 is able to make use of the metadata to
	decrypt such disks. Note though that in the current version, only the
	PBKDF2 key derival function is supported. This can mostly attributed to
	the fact that the libgcrypt library currently has no support for either
	Argon2i or Argon2id, which are the remaining KDFs supported by LUKS2. It
	wouldn't have been much of a problem to bundle those algorithms with
	GRUB itself, but it was decided against that in order to keep down the
	number of patches required for initial LUKS2 support. Adding it in the
	future would be trivial, given that the code structure is already in
	place.

	luks: Move configuration of ciphers into cryptodisk
	The luks module contains quite a lot of logic to parse cipher and

	upcoming luks2 module, as well, which is why this commit moves it into

	While the strings are probably rather specific to the LUKS modules, it
	certainly does make sense that the cryptodisk module houses code to set
	up its own internal ciphers instead of hosting that code in the luks
	module.

	Except for necessary adjustments around error handling, this commit does

	bootstrap: Add gnulib's base64 module
	The upcoming support for LUKS2 disc encryption requires us to include a
	parser for base64-encoded data, as it is used to represent salts and
	digests. As gnulib already has code to decode such data, we can just
	add it to the boostrapping configuration in order to make it available
	in GRUB.

	The gnulib module makes use of booleans via the <stdbool.h> header. As
	GRUB does not provide any POSIX wrapper header for this, but instead
	implements support for bool in <sys/types.h>, we need to patch
	base64.h to not use <stdbool.h> anymore. We unfortunately cannot include
	<sys/types.h> instead, as it would then use gnulib's internal header
	while compiling the gnulib object but our own <sys/types.h> when
	including it in a GRUB module. Because of this, the patch replaces the
	include with a direct typedef.

	A second fix is required to make available _GL_ATTRIBUTE_CONST, which
	is provided by the configure script. As base64.h does not include
	<config.h>, it is thus not available and results in a compile error.
	This is fixed by adding an include of <config-util.h>.

	json: Import upstream jsmn-1.1.0
	The upcoming support for LUKS2 encryption will require a JSON parser to
	decode all parameters required for decryption of a drive. As there is
	currently no other tool that requires JSON, and as gnulib does not
	provide a parser, we need to introduce a new one into the code base. The
	backend for the JSON implementation is going to be the jsmn library [1].
	It has several benefits that make it a very good fit for inclusion in
	GRUB:

	    - It is licensed under MIT.
	    - It is written in C89.
	    - It has no dependencies, not even libc.
	    - It is small with only about 500 lines of code.
	    - It doesn't do any dynamic memory allocation.
	    - It is testen on x86, amd64, ARM and AVR.

	The library itself comes as a single header, only, that contains both
	declarations and definitions. The exposed interface is kind of
	simplistic, though, and does not provide any convenience features
	whatsoever. Thus there will be a separate interface provided by GRUB
	around this parser that is going to be implemented in the following
	commit. This change only imports jsmn.h from tag v1.1.0 and adds it
	unmodified to a new json module with the following command:

	loader/i386/linux: Fix an underflow in the setup_header length calculation
	Recent work around x86 Linux kernel loader revealed an underflow in the
	setup_header length calculation and another related issue. Both lead to
	the memory overwrite and later machine crash.

	Currently when the GRUB copies the setup_header into the linux_params
	(struct boot_params, traditionally known as "zero page") it assumes the
	setup_header size as sizeof(linux_i386_kernel_header/lh). This is
	incorrect. It should use the value calculated accordingly to the Linux
	kernel boot protocol. Otherwise in case of pretty old kernel, to be
	exact Linux kernel boot protocol, the GRUB may write more into
	linux_params than it was expected to. Fortunately this is not very big
	issue. Though it has to be fixed. However, there is also an underflow
	which is grave. It happens when

	  sizeof(linux_i386_kernel_header/lh) > "real size of the setup_header".

	Then len value wraps around and grub_file_read() reads whole kernel into
	the linux_params overwriting memory past it. This leads to the GRUB
	memory allocator breakage and finally to its crash during boot.

	The patch fixes both issues. Additionally, it moves the code not related to
	grub_memset(linux_params)/grub_memcpy(linux_params)/grub_file_read(linux_params)
	section outside of it to not confuse the reader.

	every now and then:

	  File descriptor 4 (/dev/vda1) leaked on vgs invocation. Parent PID 1991: /usr/sbin/grub2-install

	The requirement related to the warning is dictated in the lvm man page:

	  "On invocation, lvm requires that only the standard file descriptors stdin,
	  stdout and stderr are available.  If others are found, they get closed and
	  messages are issued warning about the leak.  This warning can be suppressed by
	  setting the environment variable LVM_SUPPRESS_FD_WARNINGS."

	While it could be disabled through settings, most Linux distributions seem to
	enable it by default and the justification provided by the developer looks to
	be valid to me: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466138#15

	Rather than trying to close and reopen the file descriptor to the same file
	multiple times, which is rather cumbersome, for the sake of no vgs invocation
	could happen in between. This patch enables the close-on-exec flag (O_CLOEXEC)
	for new file descriptor returned by the open() system call, making it closed

	A side benefit of using the POSIX portable option is that it requires

	templates: Add GRUB_DISABLE_UUID
	The grub-mkconfig and 10_linux scripts by default attempt to use a UUID to
	set the root kernel command line parameter and the $root GRUB environment
	variable.

	The former can be disabled by setting the GRUB_DISABLE_LINUX_UUID variable
	to "true", but there is currently no way to disable the latter.

	The generated grub config uses the search command with the --fs-uuid option
	to find the device that has to be set as $root, i.e:

	 search --no-floppy --fs-uuid --set=root ...

	This is usually more reliable but in some cases it may not be appropriate,
	so this patch introduces a new GRUB_DISABLE_UUID variable that can be used
	to disable searching for the $root device by filesystem UUID.

	When disabled, the $root device will be set to the value specified in the
	device.map as found by the grub-probe --target=compatibility_hint option.

	When setting GRUB_DISABLE_UUID=true, the GRUB_DISABLE_LINUX_UUID and
	GRUB_DISABLE_LINUX_PARTUUID variables will also be set to "true" unless
	these have been explicitly set to "false".

	That way, the GRUB_DISABLE_UUID variable can be used to force using the

	at_keyboard: Fix unreliable key presses
	This patch fixes an issue that prevented the at_keyboard module to work
	(for me). The cause was a bad/wrong return value in the
	grub_at_keyboard_getkey() function in grub-core/term/at_keyboard.c file
	at line 237. My symptoms were to have an unresponsive keyboard. Keys
	needed to be pressed 10x and more to effectively be printed sometimes
	generating multiple key presses (after 1 or 2 sec of no printing). It
	was very problematic when typing passphrase in early stage (with
	GRUB_ENABLE_CRYPTODISK). When switched to "console" terminal input
	keyboard worked perfectly. It also worked great with the GRUB 2.02
	packaged by Debian (2.02+dfsg1-20). It was not an output issue but an
	input one.

	I've managed to analyze the issue and found that it came from the commit
	216950a4e (at_keyboard: Split protocol from controller code.). Three
	lines where moved from the fetch_key() function in
	grub-core/term/at_keyboard.c file to the beginning of
	grub_at_keyboard_getkey() function (same file). However, returning -1
	made sense when it happened in fetch_key() function but not anymore in
	grub_at_keyboard_getkey() function which should return GRUB_TERM_NO_KEY.
	I think it was just an incomplete cut-paste missing a small manual
	correction. Let's fix it.

	Note: Commit message updated by Daniel Kiper.

	templates: Fix bad test on GRUB_DISABLE_SUBMENU
	The GRUB_DISABLE_SUBMENU option is different than the others in the sense
	that it has to be set to "y" instead of "true" to be enabled.

	That causes a lot of confusion to users, some may wrongly set it to "true"
	expecting that will work the same than with most options, and some may set
	it to "yes" since for other options the value to set is a word and not a
	single character.

	This patch changes all the grub.d scripts using the GRUB_DISABLE_SUBMENU
	option, so they check if it was set to "true" instead of "y", making it
	consistent with all the other options.

	But to keep backward compatibility for users that set the option to "y" in
	/etc/default/grub file, keep testing for this value. And also do it for
	"yes", since it is a common mistake made by users caused by this option
	being inconsistent with the others.

	introduced the new command "net_dhcp", which (for now) is an alias for

	MinGW for i386-pc without this option generates a .rdata$zzz symbol that is

	This is because 'text' correctly doesn't parse as a modespec, and ought to have

	f2fs: Fix gcc9 error -Werror=maybe-uninitialized
	The function grub_get_node_path() could return uninitialized offset with

	by function grub_f2fs_get_block() because level == 0 is valid and

	The fix is to set level = -1 as return value by grub_get_node_path() to
	signify an error that the input block cannot be handled. Any caller
	should therefore check level is negative or not before processing the

	arm: Move trampolines into code section
	When creating T32->A32 transition jumps, the relocation code in grub
	will generate trampolines. These trampolines live in the .data section
	of our PE binary which means they are not marked as executable.

	This misbehavior was unmasked by commit a51f953f4ee87 ("mkimage: Align
	efi sections on 4k boundary") which made the X/NX boundary more obvious
	because everything became page aligned.

	To put things into proper order, let's move the arm trampolines into the
	.text section instead. That way everyone knows they are executable.

	hfsplus: Fix gcc9 error with -Waddress-of-packed-member
	The catkey->name could be unaligned since the address of 'void* record'
	is calculated as offset in bytes to a malloc buffer.

	The fix is using aligned buffer allocated by grub_malloc for holding
	the UTF16 string copied from catkey->name. And use that buffer as
	argument for grub_utf16_to_utf8 to convert to UTF8 strings.

	In addition, using a new copy of buffer rather than catkey->name itself
	for processing the endianess conversion, we can also get rid of the hunk
	restoring byte order of catkey->name to what it was previously.

	efi: Avoid NULL dereference if FilePath is NULL
	The UEFI specification allows LoadImage() to be called with a memory
	location only and without a device path. In this case FilePath will not be
	set in the EFI_LOADED_IMAGE_PROTOCOL.

	So in function grub_efi_get_filename() the device path argument may be
	NULL. As we cannot determine the device path in this case just return NULL
	from the function.

	This happens due to lack of support for a such usage of extern keyword

	of codebase. So, replace it with static keyword.

	Additionally, fix incorrect coding style.

	loader/i386/linux: Calculate the setup_header length
	Previously the setup_header length was just assumed to be the size of the
	linux_kernel_params struct. The linux x86 32-bit boot protocol says that the
	end of the linux_i386_kernel_header is at 0x202 + the byte value at 0x201 in
	the linux_i386_kernel_header. So, calculate the size of the header using the
	end of the linux_i386_kernel_header, rather than assume it is the size of the
	linux_kernel_params struct.

	Additionally, add some required members to the linux_kernel_params
	struct and align the content of linux_i386_kernel_header struct with
	it. New members naming was taken directly from Linux kernel source.

	linux_kernel_params and linux_i386_kernel_header structs require more
	cleanup. However, this is not urgent, so, let's do this after release.

	Even though we were parsing some DHCP options sent by the server, so far

	Change this by actually sending out DHCP DISCOVER packets instead of the
	generic (mostly empty) BOOTP BOOTREQUEST packets.

	A pure BOOTP server would ignore the extra DHCP options in the DISCOVER
	packet and would just reply with a BOOTREPLY packet, which we also

	net/dhcp: Allow receiving DHCP OFFER and ACK packets
	In respone to a BOOTREQUEST packet a BOOTP server would answer with a BOOTREPLY

	REQUEST by the client again, only to be completed by an ACKNOWLEDGE packet
	from the server.

	Teach the code dealing with those fields to check for those DHCP options first
	and use this information, if provided. We fall back to using the BOOTP
	information if those options are not used.

	msr: Add new MSR modules (rdmsr/wrmsr)
	In order to be able to read from and write to model-specific registers,
	two new modules are added. They are i386 specific, as the cpuid module.

	rdmsr module registers the command rdmsr that allows reading from a MSR.
	wrmsr module registers the command wrmsr that allows writing to a MSR.

	wrmsr module is disabled if UEFI secure boot is enabled.

	Please note that on SMP systems, interacting with a MSR that has a scope
	per hardware thread, implies that the value only applies to the
	particular cpu/core/thread that ran the command.

	Also, if you specify a reserved or unimplemented MSR address, it will
	cause a general protection exception (which is not currently being
	handled) and the system will reboot.

	sparc64: Add bios boot partition support
	Add BIOS Boot Partition support for sparc64 platforms.  This will work a
	little different than x86.  With GPT, both the OBP "load" and "boot" commands
	are partition aware and neither command can see the partition table.  Therefore
	the entire boot-loader is stored within the BIOS Boot Partition and nothing
	is stored within the bootstrap code area of MBR.

	To use it, the end user will issue the boot command with the path pointing to
	the BIOS Boot Partition.

	For example with the disk below:

	Model: Unknown (unknown)
	Disk /dev/nvme1n1: 1600GB
	Sector size (logical/physical): 512B/512B
	Partition Table: gpt

	Number  Start   End     Size    File system  Name  Flags
	1      1049kB  1075MB  1074MB   ext3
	2      1075MB  1076MB  1049kB                     bios_grub
	3      1076MB  1600GB  1599GB                     lvm

	To boot grub2 from OBP, you would use:

	ieee1275: obdisk driver
	Add a new disk driver called obdisk for IEEE1275 platforms.  Currently
	the only platform using this disk driver is SPARC, however other IEEE1275
	platforms could start using it if they so choose.  While the functionality
	within the current IEEE1275 ofdisk driver may be suitable for PPC and x86, it
	presented too many problems on SPARC hardware.

	Within the old ofdisk, there is not a way to determine the true canonical
	name for the disk.  Within Open Boot, the same disk can have multiple names
	but all reference the same disk.  For example the same disk can be referenced
	by its SAS WWN, using this form:

	/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@w5000cca02f037d6d,0

	It can also be referenced by its PHY identifier using this form:

	/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@p0

	It can also be referenced by its Target identifier using this form:

	/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@0

	Also, when the LUN=0, it is legal to omit the ,0 from the device name.  So with
	the disk above, before taking into account the device aliases, there are 6 ways
	to reference the same disk.

	Then it is possible to have 0 .. n device aliases all representing the same disk.
	Within this new driver the true canonical name is determined using the the
	IEEE1275 encode-unit and decode-unit commands when address_cells == 4.  This
	will determine the true single canonical name for the device so multiple ihandles
	are not opened for the same device.  This is what frequently happens with the old
	ofdisk driver.  With some devices when they are opened multiple times it causes
	the entire system to hang.

	Another problem solved with this driver is devices that do not have a device
	alias can be booted and used within GRUB. Within the old ofdisk, this was not
	possible, unless it was the original boot device.  All devices behind a SAS
	or SCSI parent can be found.   Within the old ofdisk, finding these disks
	relied on there being an alias defined.  The alias requirement is not
	necessary with this new driver.  It can also find devices behind a parent
	after they have been hot-plugged.  This is something that is not possible
	with the old ofdisk driver.

	The old ofdisk driver also incorrectly assumes that the device pointing to by a
	device alias is in its true canonical form. This assumption is never made with
	this new driver.

	Another issue solved with this driver is that it properly caches the ihandle
	for all open devices.  The old ofdisk tries to do this by caching the last
	opened ihandle.  However this does not work properly because the layer above
	does not use a consistent device name for the same disk when calling into the
	driver.  This is because the upper layer uses the bootpath value returned within
	/chosen, other times it uses the device alias, and other times it uses the
	value within grub.cfg.  It does not have a way to figure out that these devices
	are the same disk.  This is not a problem with this new driver.

	Due to the way GRUB repeatedly opens and closes the same disk. Caching the
	ihandle is important on SPARC.  Without caching, some SAS devices can take
	15 - 20 minutes to get to the GRUB menu. This ihandle caching is not possible
	without correctly having the canonical disk name.

	When available, this driver also tries to use the deblocker #blocks and
	a way of determining the disk size.

	Finally and probably most importantly, this new driver is also capable of
	seeing all partitions on a GPT disk.  With the old driver, the GPT
	partition table can not be read and only the first partition on the disk
	can be seen.

2019-03-05  Colin Watson  <cjwatson@ubuntu.com>

	gnulib: Upgrade Gnulib and switch to bootstrap tool
	Upgrade Gnulib files to 20190105.

	It's much easier to maintain GRUB's use of portability support files
	from Gnulib when the process is automatic and driven by a single
	configuration file, rather than by maintainers occasionally running
	gnulib-tool and committing the result.  Removing these
	automatically-copied files from revision control also removes the
	temptation to hack the output in ways that are difficult for future
	maintainers to follow.  Gnulib includes a "bootstrap" program which is
	designed for this.

	The canonical way to bootstrap GRUB from revision control is now
	"./bootstrap", but "./autogen.sh" is still useful if you just want to
	generate the GRUB-specific parts of the build system.

	GRUB now requires Autoconf >= 2.63 and Automake >= 1.11, in line with
	Gnulib.

	Gnulib source code is now placed in grub-core/lib/gnulib/ (which should
	not be edited directly), and GRUB's patches are in
	grub-core/lib/gnulib-patches/.  I've added a few notes to the developer
	manual on how to maintain this.

	util: Detect more I/O errors
	Many of GRUB's utilities don't check anywhere near all the possible

	copying a file, it won't notice.  There were missing checks for the
	return values of write, fflush, fsync, and close (or the equivalents on
	other OSes), all of which must be checked.

	I tried to be consistent with the existing logging practices of the
	various hostdisk implementations, but they weren't entirely consistent
	to start with so I used my judgement.  The result at least looks
	reasonable on GNU/Linux when I provoke a write error:

	  Installing for x86_64-efi platform.
	  grub-install: error: cannot copy `/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed' to `/boot/efi/EFI/debian/grubx64.efi': No space left on device.

	travis: Add Travis CI config file
	There is a really convenient service for open source project from Travis
	CI: They allow for free CI testing using their infrastructure.

	GRUB has had issues with broken builds for various targets for a long time
	already. The main reason is a lack of CI to just do smoke tests on whether
	all targets still at least compile.

	This patch adds a Travis config file which builds (almost) all currently
	available targets.

	On top of that, this Travis config also runs a small execution test on the
	x86_64-efi target.

	All of this config file can easily be extended further on. It probably
	makes sense to do something similar to the u-boot test infrastructure
	that communicates with the payload properly. Going forward, we also will
	want to do more QEMU runtime checks for other targets.

	Currently, with this config alone, I already see about half of the available
	targets as broken. So it's definitely desperately needed :).

	normal/menu: Do not treat error values as key presses

	they are not ready yet.

	      if (! KEYBOARD_ISREADY (grub_inb (KEYBOARD_REG_STATUS)))
	        return -1;

	Currently, that is treated as a key press, and the menu time-out is

	manually has to select a menu entry. Therefore, adapt the condition to
	require the key value also to be greater than 0.

	`GRUB_TERM_NO_KEY` is defined as 0, so the condition could be collapsed

	mkimage: Align efi sections on 4k boundary
	There is UEFI firmware popping up in the wild now that implements stricter
	permission checks using NX and write protect page table entry bits.

	This means that firmware now may fail to load binaries if its individual
	sections are not page aligned, as otherwise it can not ensure permission
	boundaries.

	So let's bump all efi section alignments up to 4k (EFI page size). That way
	we will stay compatible going forward.

	Unfortunately our internals can't deal very well with a mismatch of alignment
	between the virtual and file offsets, so we have to also pad our target
	binary a bit.

	A certain amount of dynamic space is required for the handover from

	uboot: Add the missing disk write operation support
	uboot_disk_write() is currently lacking the write support
	to storage devices because, historically, those devices did not
	implement block_write() in U-Boot.

	The solution has been tested using a patched U-Boot loading
	and booting GRUB in a QEMU vexpress-a9 environment.
	The disk write operations were triggered with GRUB's save_env

	tpm: Fix bug in GRUB2 TPM module
	The value of tpm_handle changes between successive calls to grub_tpm_handle_find(),
	as instead of simply copying the stored pointer we end up taking the address of
	said pointer when using the cached value of grub_tpm_handle.

	This causes grub_efi_open_protocol() to return a nullptr in grub_tpm2_execute()
	and grub_tpm2_log_event(). Said nullptr goes unchecked and
	efi_call_5(tpm->hash_log_extend_event,...) ends up jumping to 0x0, Qemu crashes
	once video ROM is reached at 0xb0000.

	This patch seems to do the trick of fixing that bug, but we should also ensure
	that all calls to grub_efi_open_protocol() are checked so that we don't start
	executing low memory.

	grub-mkconfig/20_linux_xen: Support multiple early initrd images
	Add support for multiple, shared, early initrd images. These early
	images will be loaded in the order declared, and all will be loaded
	before the initrd image.

	While many classes of data can be provided by early images, the
	immediate use case would be for distributions to provide CPU
	microcode to mitigate the Meltdown and Spectre vulnerabilities.

	Xen has also support to load microcode updates provided as additional
	modules by the bootloader.

	There are two environment variables provided for declaring the early
	images.

	* GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare
	  images that are provided by the distribution or installed packages.
	  If undeclared, this will default to a set of common microcode image
	  names.

	* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User
	  images will be loaded after the stock images.

	These separate configurations allow the distribution and user to
	declare different image sets without clobbering each other.

	This also makes a minor update to ensure that UUID partition labels
	stay disabled when no initrd image is found, even if early images are
	present.

	This is basically a copy of a698240d "grub-mkconfig/10_linux: Support
	multiple early initrd images" by Matthew S. Turnbull.

	- Import zstd-1.3.6 from upstream
	- Add zstd's module.c file
	- Add the zstd module to Makefile.core.def

	Import zstd-1.3.6 from upstream [1]. Only the files need for decompression
	are imported. I used the latest zstd release, which includes patches [2] to
	build cleanly in GRUB.

	I included the script used to import zstd-1.3.6 below at the bottom of the
	commit message.

	Upstream zstd commit hash: 4fa456d7f12f8b27bd3b2f5dfd4f46898cb31c24
	Upstream zstd commit name: Merge pull request #1354 from facebook/dev

	Zstd requires some posix headers, which it gets from posix_wrap.
	This can be checked by inspecting the .Po files generated by automake,
	which contain the header dependencies. After building run the command
	`cat grub-core/lib/zstd/.deps-core/*.Po` to see the dependencies [3].
	The only OS dependencies are:

	- stddef.h, which is already a dependency in posix_wrap, and used for size_t
	  by lzo and xz.
	- stdarg.h, which comes from the grub/misc.h header, and we don't use in zstd.

	All the types like uint64_t are typedefed to grub_uint64_t under the hood.
	The only exception is size_t, which comes from stddef.h. This is already the
	case for lzo and xz. I don't think there are any cross-compilation concerns,
	because cross-compilers provide their own system headers (and it would already
	be broken).

	verifiers: fix double close on pgp's sig file descriptor
	An error emerged as when I was testing the verifiers branch, so instead
	of putting it in pgp prefix, the verifiers is used to reflect what the
	patch is based on.

	While running verify_detached, grub aborts with error.

	verify_detached /@/.snapshots/1/snapshot/boot/grub/grub.cfg
	/@/.snapshots/1/snapshot/boot/grub/grub.cfg.sig

	alloc magic is broken at 0x7beea660: 0
	Aborted. Press any key to exit.

	The error is caused by sig file descriptor been closed twice, first time
	in grub_verify_signature() to which it is passed as parameter. Second in
	grub_cmd_verify_signature() or in whichever opens the sig file
	descriptor. The second close is not consider as bug to me either, as in
	common rule of what opens a file has to close it to avoid file
	descriptor leakage.

	After all the design of grub_verify_signature() makes it difficult to keep
	a good trace on opened file descriptor from it's caller. Let's refine
	the application interface to accept file path rather than descriptor, in
	this way the caller doesn't have to care about closing the descriptor by
	delegating it to grub_verify_signature() with full tracing to opened
	file descriptor by itself.

	Also making it clear that sig descriptor is not referenced in error
	returning path of grub_verify_signature_init(), so it can be closed
	directly by it's caller. This also makes delegating it to
	grub_pubkey_close() infeasible to help in relieving file descriptor
	leakage as it has to depend on uncertainty of ctxt fields in error
	returning path.

	efi: Add EFI shim lock verifier
	This module provides shim lock verification for various kernels
	if UEFI secure boot is enabled on a machine.

	It is recommended to put this module into GRUB2 standalone image
	(avoid putting iorw and memrw modules into it; they are disallowed
	if UEFI secure boot is enabled). However, it is also possible to use
	it as a normal module. Though such configurations are more fragile
	and less secure due to various limitations.

	If the module is loaded and UEFI secure boot is enabled then:
	  - module itself cannot be unloaded (persistent module),
	  - the iorw and memrw modules cannot be loaded,
	  - if the iorw and memrw modules are loaded then
	    machine boot is disabled,
	  - GRUB2 defers modules and ACPI tables verification to
	    other verifiers.

	This patch fixes above mentioned issue. Information about missing devices
	is stored in the data->devices_attached[] array as NULL value in dev
	member. Rescan is triggered only if no information is found for a given
	device. This means that only first time read triggers rescan.

	python: Use AM_PATH_PYTHON to determine interpreter for gentpl.py
	gentpl.py is python2/3-agnostic, but there's no way to cause it
	to be run with any interpreter other than 'python', it's just
	hard-coded into Makefile.common that way. Adjust that to use
	AM_PATH_PYTHON (provided by automake) to find an interpreter
	and run gentpl.py with that instead. This makes grub buildable
	when `python` does not exist (but rather `python3` or `python2`
	or `python2.7`, etc.) Minimum version is set to 2.6 as this is
	the first version with `__future__.print_function` available.

	Note, AM_PATH_PYTHON respects the PYTHON environment variable
	and will treat its value as the *only* candidate for a valid
	interpreter if it is set - when PYTHON is set, AM_PATH_PYTHON
	will not try to find any alternative interpreter, it will only
	check whether the interpreter set as the value of PYTHON meets
	the requirements and use it if so or fail if not. This means
	that when using grub's `autogen.sh`, as it too uses the value
	of the PYTHON environment variable (and if it is not set, just
	sets it to 'python') you cannot rely on AM_PATH_PYTHON
	interpreter discovery. If your desired Python interpreter is
	not just 'python', you must set the PYTHON environment variable,
	e.g. 'PYTHON=/usr/local/bin/python3 ./autogen.sh'. The specified
	interpreter will then be used both by autogen.sh itself and by
	the autotools-driven build scripts.

	This is a cryptographically signed message in MIME format.

	Date: Thu, 9 Aug 2018 07:27:35 +0200

	Currently, the GRUB payload for coreboot does not detect the Western
	Digital hard disk WDC WD20EARS-60M AB51 connected to the ASRock E350M1,
	as that takes over ten seconds to spin up.

	```

	disk/ahci.c:539: port 0, err: 0
	disk/ahci.c:543: port 0, err: 0

	disk/ahci.c:593: port 0 is busy
	disk/ahci.c:621: cleaning up failed devs
	```

	GRUB detects the drive, when either unloading the module *ahci*, and
	then loading it again, or when doing a warm reset.

	As the ten second time-out is too short, increase it to 32 seconds,
	used by SeaBIOS. which detects the drive successfully.

	The AHCI driver in libpayload uses 30 seconds, and that time-out was
	added in commit 354066e1 (libpayload: ahci: Increase timeout for
	signature reading) with the description below.

	> We can't read the drives signature before it's ready, i.e. spun up.
	> So set the timeout to the standard 30s. Also put a notice on the

	efi: Restrict arm/arm64 linux loader initrd placement
	The 32-bit arm Linux kernel is built as a zImage, which self-decompresses
	down to near start of RAM. In order for an initrd/initramfs to be
	accessible, it needs to be placed within the first ~768MB of RAM.
	The initrd loader built into the kernel EFI stub restricts this down to
	512MB for simplicity - so enable the same restriction in grub.

	For arm64, the requirement is within a 1GB aligned 32GB window also
	covering the (runtime) kernel image. Since the EFI stub loader itself
	will attempt to relocate to near start of RAM, force initrd to be loaded
	completely within the first 32GB of RAM.

	i386/linux: Add support for ext_lfb_base
	The EFI Graphics Output Protocol can return a 64-bit
	linear frame buffer address in some firmware/BIOS
	implementations. We currently only store the lower
	32-bits in the lfb_base. This will eventually be
	passed to Linux kernel and the efifb driver will
	incorrectly interpret the framebuffer address as
	32-bit address.

	The Linux kernel has already added support to handle
	64-bit linear framebuffer address in the efifb driver
	since quite some time now.

	This patch adds the support for 64-bit linear frame
	buffer address in GRUB to address the above mentioned
	scenario.

	efi/console: Fix the "enter" key not working on x86 tablets
	Most 8" or 7" x86 Windows 10 tablets come with volume up/down buttons and
	a power-button. In their UEFI these are almost always mapped to arrow
	up/down and enter.

	Pressing the volume buttons (sometimes by accident) will stop the
	menu countdown, but the power-button / "enter" key was not being recognized
	as enter, so the user would be stuck at the grub menu.

	The problem is that these tablets send scan_code 13 or 0x0d for the
	power-button, which officialy maps to the F3 key. They also set
	unicode_char to 0x0d.

	This commit recognizes the special case of both scan_code and unicode_char
	being set to 0x0d and treats this as an enter key press.

	This fixes things getting stuck at the grub-menu and allows the user
	to choice a grub-menu entry using the buttons on the tablet.

	xfs: Accept filesystem with sparse inodes
	The sparse inode metadata format became a mkfs.xfs default in
	xfsprogs-4.16.0, and such filesystems are now rejected by grub as
	containing an incompatible feature.

	In essence, this feature allows xfs to allocate inodes into fragmented
	freespace.  (Without this feature, if xfs could not allocate contiguous
	space for 64 new inodes, inode creation would fail.)

	In practice, the disk format change is restricted to the inode btree,
	which as far as I can tell is not used by grub.  If all you're doing
	today is parsing a directory, reading an inode number, and converting
	that inode number to a disk location, then ignoring this feature
	should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED

	I did some brief testing of this patch by hacking up the regression
	tests to completely fragment freespace on the test xfs filesystem, and
	then write a large-ish number of inodes to consume any existing
	contiguous 64-inode chunk.  This way any files the grub tests add and
	traverse would be in such a fragmented inode allocation.  Tests passed,
	but I'm not sure how to cleanly integrate that into the test harness.

	fs: Add F2FS support
	"F2FS (Flash-Friendly File System) is flash-friendly file system which was merged
	into Linux kernel v3.8 in 2013.

	The motive for F2FS was to build a file system that from the start, takes into
	account the characteristics of NAND flash memory-based storage devices (such as
	solid-state disks, eMMC, and SD cards).

	F2FS was designed on a basis of a log-structured file system approach, which
	remedies some known issues of the older log structured file systems, such as
	the snowball effect of wandering trees and high cleaning overhead. In addition,
	since a NAND-based storage device shows different characteristics according to
	its internal geometry or flash memory management scheme (such as the Flash
	Translation Layer or FTL), it supports various parameters not only for
	configuring on-disk layout, but also for selecting allocation and cleaning
	algorithm.", quote by https://en.wikipedia.org/wiki/F2FS.

	The source codes for F2FS are available from:

	This patch fixes the build error by cleaning up the ambiguity of placing
	aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
	grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
	has to be packed, to ensure the structure is bit-to-bit mapped to the format
	laid on disk. I think we could blame to copy and paste error here for the

	Add support for multiple, shared, early initrd images. These early

	before the initrd image.

	While many classes of data can be provided by early images, the
	immediate use case would be for distributions to provide CPU
	microcode to mitigate the Meltdown and Spectre vulnerabilities.

	There are two environment variables provided for declaring the early
	images.

	* GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare
	  images that are provided by the distribution or installed packages.
	  If undeclared, this will default to a set of common microcode image
	  names.

	* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User
	  images will be loaded after the stock images.

	These separate configurations allow the distribution and user to
	declare different image sets without clobbering each other.

	This also makes a minor update to ensure that UUID partition labels
	stay disabled when no initrd image is found, even if early images are
	present.

	.mod files: Strip annobin annotations and .eh_frame, and their relocations
	This way debuginfo built from the .module will still include this

	mkimage: avoid copying relocations for sections that won't be copied.
	Some versions of gcc include a plugin called "annobin", and in some
	build systems this is enabled by default.  This plugin creates special
	ELF note sections to track which ABI-breaking features are used by a
	binary, as well as a series of relocations to annotate where.

	If grub is compiled with this feature, then when grub-mkimage translates
	the binary to another file format which does not strongly associate
	relocation data with sections (i.e. when platform is *-efi), these
	relocations appear to be against the .text section rather than the
	original note section.  When the binary is loaded by the PE runtime
	loader, hilarity ensues.

	This issue is not necessarily limited to the annobin, but could arise
	any time there are relocations in sections that are not represented in
	grub-mkimage's output.

	This patch seeks to avoid this issue by only including relocations that
	refer to sections which will be included in the final binary.

	As an aside, this should also obviate the need to avoid -funwind-tables,
	-fasynchronous-unwind-tables, and any sections similar to .eh_frame in
	the future.  I've tested it on x86-64-efi with the following gcc command
	line options (as recorded by -grecord-gcc-flags), but I still need to
	test the result on some other platforms that have been problematic in
	the past (especially ARM Aarch64) before I feel comfortable making
	changes to the configure.ac bits:

	libgcrypt: Import replacement CRC operations
	The CRC implementation imported from libgcrypt 1.5.3 is arguably
	non-free, due to being encumbered by the restrictive Internet Society
	licence on RFCs (see e.g. https://wiki.debian.org/NonFreeIETFDocuments).
	Fortunately, libgcrypt has since replaced it with a version that is both
	reportedly better-optimised and doesn't suffer from this encumbrance.

	The ideal solution would be to update to a new version of libgcrypt, and
	I spent some time trying to do that.  However, util/import_gcry.py
	requires complex modifications to cope with the new version, and I
	stalled part-way through; furthermore, GRUB's libgcrypt tree already
	contains some backports of upstream changes.  Rather than allowing the
	perfect to be the enemy of the good, I think it's best to backport this
	single change to at least sort out the licensing situation.  Doing so
	won't make things any harder for a future wholesale upgrade.

	This commit is mostly a straightforward backport of
	https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=commitdiff;h=06e122baa3321483a47bbf82fd2a4540becfa0c9,
	but I also imported bufhelp.h from libgcrypt 1.7.0 (newer versions
	required further changes elsewhere).

	I've tested that "hashsum -h crc32" still produces correct output for a
	variety of files on both i386-pc and x86_64-emu targets.

	chainloader: Fix wrong break condition (must be AND not, OR)
	The definition of bpb's num_total_sectors_16 and num_total_sectors_32
	is that either the 16-bit field is non-zero and is used (in which case
	eg mkfs.fat sets the 32-bit field to zero), or it is zero and the
	32-bit field is used. Therefore, a BPB is invalid only if *both*
	fields are zero; having one field as zero and the other as non-zero is
	the case to be expected. (Indeed, according to Microsoft's specification
	one of the fields *must* be zero, and the other non-zero.)

	This affects all users of grub_chainloader_patch_bpb which are in
	chainloader.c, freedos.c, and ntldr.c

	Some descriptions of the semantics of these two fields:

	https://www.win.tue.nl/~aeb/linux/fs/fat/fat-1.html

	  The old 2-byte fields "total number of sectors" and "number of
	  sectors per FAT" are now zero; this information is now found in
	  the new 4-byte fields.

	(Here given in the FAT32 EBPB section but the total sectors 16/32 bit
	fields semantic is true of FAT12 and FAT16 too.)

	https://wiki.osdev.org/FAT#BPB_.28BIOS_Parameter_Block.29

	  19 | 2 | The total sectors in the logical volume. If this value is 0,
	  it means there are more than 65535 sectors in the volume, and the actual
	  count is stored in "Large Sectors (bytes 32-35).

	  32 | 4 | Large amount of sector on media. This field is set if there
	  are more than 65535 sectors in the volume.

	(Doesn't specify what the "large" field is set to when unused, but as
	mentioned mkfs.fat sets it to zero then.)

	https://technet.microsoft.com/en-us/library/cc976796.aspx

	  0x13 | WORD | 0x0000 |
	  Small Sectors . The number of sectors on the volume represented in 16
	  bits (< 65,536). For volumes larger than 65,536 sectors, this field
	  has a value of zero and the Large Sectors field is used instead.

	  0x20 | DWORD | 0x01F03E00 |
	  Large Sectors . If the value of the Small Sectors field is zero, this
	  field contains the total number of sectors in the FAT16 volume. If the
	  value of the Small Sectors field is not zero, the value of this field
	  is zero.

	https://staff.washington.edu/dittrich/misc/fatgen103.pdf page 10

	  BPB_TotSec16 | 19 | 2 |
	  This field is the old 16-bit total count of sectors on the volume.
	  This count includes the count of all sectors in all four regions of the
	  volume. This field can be 0; if it is 0, then BPB_TotSec32 must be
	  non-zero. For FAT32 volumes, this field must be 0. For FAT12 and
	  FAT16 volumes, this field contains the sector count, and
	  BPB_TotSec32 is 0 if the total sector count “fits” (is less than
	  0x10000).

	  BPB_TotSec32 | 32 | 4 |
	  This field is the new 32-bit total count of sectors on the volume.
	  This count includes the count of all sectors in all four regions of the
	  volume. This field can be 0; if it is 0, then BPB_TotSec16 must be
	  non-zero. For FAT32 volumes, this field must be non-zero. For
	  FAT12/FAT16 volumes, this field contains the sector count if
	  BPB_TotSec16 is 0 (count is greater than or equal to 0x10000).

	(This specifies that an unused BPB_TotSec32 field is set to zero.)

	By the way fix offsets in include/grub/fat.h.

	ahci: Improve error handling
	Check the error bits in the interrupt status register. According to the
	AHCI 1.2 spec, "Interrupt sources that are disabled (‘0’) are still
	reflected in the status registers.", so this should work even though
	grub uses polling

	This fixes the following problem on a Fujitsu E744 laptop:

	Sometimes there is a very long delay (up to several minutes) when
	booting from hard disk. It seems accessing the DVD drive (which has no
	disk inserted) sometimes fails with some errors, which leads to each
	access being stalled until the 20s timeout triggers. This seems to
	happen when grub is trying to read filesystem/partition data.

	The problem is that the command_issue bit that is checked in the loop is
	only reset if the "HBA receives a FIS which clears the BSY, DRQ, and ERR
	bits for the command", but the ERR bit is never cleared. Therefore
	command_issue is never reset and grub waits for the timeout.

	The relevant bit in our case is the Task File Error Status (TFES), which
	is equivalent to the ERR bit 0 in tfd. But this patch also checks
	the other error bits except for the "Interface non-fatal error status"
	bit.

	unix exec: avoid atexit handlers when child exits
	The `grub_util_exec_redirect_all` helper function can be used to
	spawn an executable and redirect its output to some files. After calling
	`fork()`, the parent will wait for the child to terminate with
	`waitpid()` while the child prepares its file descriptors, environment
	and finally calls `execvp()`. If something in the children's setup
	fails, it will stop by calling `exit(127)`.

	Calling `exit()` will cause any function registered via `atexit()` to be
	executed, which is usually the wrong thing to do in a child. And
	actually, one can easily observe faulty behaviour on musl-based systems
	without modprobe(8) installed: executing `grub-install --help` will call
	`grub_util_exec_redirect_all` with "modprobe", which obviously fails if
	modprobe(8) is not installed. Due to the child now exiting and invoking
	the `atexit()` handlers, it will clean up some data structures of the
	parent and cause it to be deadlocked in the `waitpid()` syscall.

	The issue can easily be fixed by calling `_exit(127)` instead, which is
	especially designed to be called when the atexit-handlers should not be
	executed.

	* grub-core/fs/udf.c: Add support for UUID
	Use same algorithm as in libblkid from util-linux v2.30.

	1. Take first 16 bytes from UTF-8 encoded string of VolumeSetIdentifier
	2. If all bytes are hexadecimal digits, convert to lowercase and use as UUID
	3. If first 8 bytes are not all hexadecimal digits, convert those 8 bytes
	   to their hexadecimal representation, resulting in 16 bytes for UUID
	4. Otherwise, compose UUID from two parts:
	   1. part: converted first 8 bytes (which are hexadecimal digits) to lowercase
	   2. part: encoded following 4 bytes to their hexadecimal representation (16 bytes)

	So UUID would always have 16 hexadecimal digits in lowercase variant.

	According to UDF specification, first 16 Unicode characters of
	VolumeSetIdentifier should be unique value and first 8 should be
	hexadecimal characters.

	In most cases all 16 characters are hexadecimal, but e.g. MS Windows
	format.exe set only first 8 as hexadecimal and remaining as fixed
	(non-unique) which violates specification.

	Allow GRUB to mount ext2/3/4 filesystems that have the encryption feature.
	On such a filesystem, inodes may have EXT4_ENCRYPT_FLAG set.
	For a regular file, this means its contents are encrypted; for a
	directory, this means the filenames in its directory entries are
	encrypted; and for a symlink, this means its target is encrypted.  Since
	GRUB cannot decrypt encrypted contents or filenames, just issue an error
	if it would need to do so.  This is sufficient to allow unencrypted boot
	files to co-exist with encrypted files elsewhere on the filesystem.

	(Note that encrypted regular files and symlinks will not normally be
	encountered outside an encrypted directory; however, it's possible via
	hard links, so they still need to be handled.)

	Tested by booting from an ext4 /boot partition on which I had run
	'tune2fs -O encrypt'.  I also verified that the expected error messages
	are printed when trying to access encrypted directories, files, and
	symlinks from the GRUB command line.  Also ran 'sudo ./grub-fs-tester
	ext4_encrypt'; note that this requires e2fsprogs v1.43+ and Linux v4.1+.

	After this patch it now returns the correct value:

	In this case we use max_addr to put remapper. Unfortunately we increment
	max_addr as well in this case resulting in virt mapping mapping page
	at old max_addr and trying to boot using new max_addr.

	ofnet: implement the receive buffer
	get_card_packet() from ofnet.c allocates a netbuff based on the device's MTU:

	 nb = grub_netbuff_alloc (dev->mtu + 64 + 2);

	In the case when the MTU is large, and the received packet is
	relatively small, this leads to allocation of significantly more memory,
	than it's required. An example could be transmission of TFTP packets
	with 0x400 blksize via a network card with 0x10000 MTU.

	This patch implements a per-card receive buffer in a way similar to efinet.c,

	multiboot2: Add support for relocatable images
	Currently multiboot2 protocol loads image exactly at address specified in
	ELF or multiboot2 header. This solution works quite well on legacy BIOS
	platforms. It is possible because memory regions are placed at predictable
	addresses (though I was not able to find any spec which says that it is
	strong requirement, so, it looks that it is just a goodwill of hardware
	designers). However, EFI platforms are more volatile. Even if required
	memory regions live at specific addresses then they are sometimes simply
	not free (e.g. used by boot/runtime services on Dell PowerEdge R820 and
	OVMF). This means that you are not able to just set up final image
	destination on build time. You have to provide method to relocate image
	contents to real load address which is usually different than load address
	specified in ELF and multiboot2 headers.

	This patch provides all needed machinery to do self relocation in image code.
	First of all GRUB2 reads min_addr (min. load addr), max_addr (max. load addr),
	align (required image alignment), preference (it says which memory regions are
	preferred by image, e.g. none, low, high) from multiboot_header_tag_relocatable
	header tag contained in binary (at this stage load addresses from multiboot2
	and/or ELF headers are ignored). Later loader tries to fulfill request (not only
	that one) and if it succeeds then it informs image about real load address via
	multiboot_tag_load_base_addr tag. At this stage GRUB2 role is finished. Starting
	from now executable must cope with relocations itself using whole static and
	dynamic knowledge provided by boot loader.

	This patch does not provide functionality which could do relocations using
	ELF relocation data. However, I was asked by Konrad Rzeszutek Wilk and Vladimir
	'phcoder' Serbinenko to investigate that thing. It looks that relevant machinery
	could be added to existing code (including this patch) without huge effort.
	Additionally, ELF relocation could live in parallel with self relocation provided
	by this patch. However, during research I realized that first of all we should
	establish the details how ELF relocatable image should look like and how it should
	be build. At least to build proper test/example files.

	So, this patch just provides support for self relocatable images. If ELF file
	with relocs is loaded then GRUB2 complains loudly and ignores it. Support for
	such files will be added later.

	This patch was tested with Xen image which uses that functionality. However, this Xen
	feature is still under development and new patchset will be released in about 2-3 weeks.

	multiboot2: Do not pass memory maps to image if EFI boot services are enabled

	needs. Usually we do not care as we would have finished boot services.
	If we keep boot services then it is easier/safer to not provide maps.

	dns: fix buffer overflow for data->addresses in recv_hook
	We may get more than one response before exiting out of loop in
	grub_net_dns_lookup, but buffer was allocated for the first response only,
	so storing answers from subsequent replies wrote past allocated size.
	We never really use more than the very first address during lookup so there
	is little point in collecting all of them. Just quit early if we already have
	some reply.

	Code needs serious redesign to actually collect multiple answers
	and select the best fit according to requested type (IPv4 or IPv6).

	xfs: accept filesystem with meta_uuid
	XFS V5 stores UUID in metadata and compares them with superblock UUID.
	To allow changing of user-visible UUID it stores original value in new
	superblock field (meta_uuid) and sets incompatible flag to indicate that
	new field must be used to verify metadata. Our driver currently does not
	check metadata UUID so simply accept such filesystem.

	configure: set -fno-pie together with -fno-PIE
	OpenBSD 5.9 apparently defaults to -fpie. We use -fno-PIE when appropriate
	already, but that is not enough - it does not turn off -fpie.

	Actually check for -fPIE is not precise enough. __PIE__ is set for both
	-fpie and -fPIE but with different values. As far as I can tell, both
	options were introduced at the same time, so both should always be supported.

	net: fix ipv6 routing
	ipv6 routing in grub2 is broken, we cannot talk to anything outside our local
	network or anything that doesn't route in our global namespace.  This patch
	fixes this by doing a couple of things

	1) Read the router information off of the router advertisement.  If we have a
	router lifetime we need to take the source address and create a route from it.

	2) Changes the routing stuff slightly to allow you to specify a gateway _and_ an
	interface.  Since the router advertisements come in on the link local address we
	need to associate it with the global address on the card.  So when we are
	processing the router advertisement, either use the SLAAC interface we create
	and add the route to that interface, or loop through the global addresses we
	currently have on our interface and associate it with one of those addresses.
	We need to have a special case here for the default route so that it gets used,
	we do this by setting the masksize to 0 to mean it encompasses all networks.
	The routing code will automatically select the best route so if there is a
	closer match we will use that.

	With this patch I can now talk to ipv6 addresses outside of my local network.
	Thanks,

	menu_entry: Disable cursor during update_screen()
	When running grub in a VGA console of a KVM pseries guest on PowerPC,
	you can see the cursor sweeping over the whole line when entering a

	the whole line when entering a character in editor mode, and drawing
	characters is quite a slow operation with the firmware used for the
	powerpc pseries guests (SLOF).
	To avoid this ugliness, the cursor should be disabled when refreshing

	configure: Add -fno-unwind-tables if supported.
	Unwind tables are useless for us bt consume space if present. Ensure that they

	module-verifier: allow limited-range relocations on sparc64.
	clang as incomplete mcmodel=large support. As we don't currently need full
	mcmodel=large support for sparc64, relax those checks.

	Disable build-time module check on emu.
	On emu some checks can be laxer like check for relocation range. Additionally
	module loading in emu is rarely used. So skip this check rather than making
	it laxer for all platforms. In ideal we may want to have slightly different
	check for emu but for now this is good enough.

	configure: Fix grub_cv_cc_fno_unwind_tables check.
	Check tries -fno-dwarf2-cfi-asm but adds -fno-asynchronous-unwind-tables
	to TARGET_CFLAGS. Fix this.

	Add -mno-stack-arg-probe on mingw.
	This argument disables generation of calls to __chkstk_ms. Those calls are
	useless on GRUB as function is dummy. Yet they increase module size and
	use limited-range relocations which may not work under some memory layouts.
	We currently don't use such layouts on concerned platforms but lt's correct
	this.

	Strip .ARM.exidx
	This section is generated by clang and is useful only for debugging.
	It contains exotic relocations, so strip them to avoid them interferring
	with module loading.

	module-verifier: Check range-limited relative relocations.
	Check that they point to the same module, so will end up in the same
	chunk of memory.

	xen/relocator: Use local symbol to ensure that code is relocation-free.

	backtrace: Fix register call syntax

	Verify modules on build-time rather than failing in runtime.

	sparc64: Fix assembly to let compiler to fill in memory references.
	This fixes the use of not fully relocatable (they assume that variables are
	under 4G limit in virtual memory) references.

	devmapper: check for valid device abstraction in get_grub_dev
	This was lost when code was refactored. Patch restores previous behavior.

	It is still not clear whether this is the right one. Due to the way we
	detect DM abstraction, partitions on DM are skipped, we fall through to
	generic detection which ends up in assuming parent device is BIOS disk.

	It is useful to install GRUB on VM disk from the host. But it also means
	that GRUB will mistakenly allow install on real system as well.

	For now let's fix regression; future behavior needs to be discussed.

	windows: correct LBA in generated EFI HDD media paths
	GRUB keeps partition offset and size in units of 512B sectors. Media paths
	are defined in terms of LBA which are presumed to match HDD sector size.

	This is probably cosmetic (EFI requires that partition is searched by GUID)
	and still incorrect if GPT was created using different logical block size.
	But current code is obviously wrong and new has better chances to be correct.

	lsefimmap: support persistent memory and other UEFI 2.5 features
	This should accompany
		76ce1de740 Translate UEFI persistent memory type

	1. Add a string for the EfiPersistentMemory type 14 that was
	added in UEFI 2.5.

	2. Decode the memory attributes that were added in UEFI 2.5:
	* NV (non-volatile)
	* MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
	  with partial memory mirroring)
	* RO (read-only)

	3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
	values rather than misusing SI power-of-ten units (KB, MB, etc.)

	4. The lsmmap command only decodes memory ranges sizes up to GiB scale
	units.  Persistent memory ranges will reach into the TiB scale.
	Since 64-bit size field supports TiB, PiB, and EiB, decode all of
	them for completeness.

	5. In the lsefimmap command, rewrite the print statements to
	* avoid rounding
	* avoid a big nested if/else tree.

	For example: In the sixth entry below, the value of 309MB implies
	316416KB but is really reporting 316436KB.

	Widen the size column to 6 digits to accommodate typical cases.
	The worst case value would require 14 digits; if that happens,
	let the columns get out of sync.

	Old format:

	tcp: ack when we get an OOO/lost packet
	While adding tcp window scaling support I was finding that I'd get some packet
	loss or reordering when transferring from large distances and grub would just
	timeout.  This is because we weren't ack'ing when we got our OOO packet, so the
	sender didn't know it needed to retransmit anything, so eventually it would fill
	the window and stop transmitting, and we'd time out.  Fix this by ACK'ing when
	we don't find our next sequence numbered packet.  With this fix I no longer time
	out.  Thanks,

	configure: force o32 ABI on MIPS
	GRUB code expects O32 or N32. N32 is less tested than O32, so we prefer to
	compile with O32. Some systems (e.g. GNU Guix) default to using newer
	n64 or n32 ABI. Try to find suitable options to force o32.

	For GCC this is simply -mabi=32. While clang supports this option as well,
	o32 ABI is valid for MIPS target and n32/64 ABI are valid for MIPS64 target
	only, so use "-target mips/mipsel -mabi=32".

	progress: avoid NULL dereference for net files
	From original patch by dann frazier <dann.frazier@canonical.com>:

	  grub_net_fs_open() saves off a copy of the file structure it gets passed and
	  uses it to create a bufio structure. It then overwrites the passed in file
	  structure with this new bufio structure. Since file->name doesn't get set
	  until we return back to grub_file_open(), it means that only the bufio
	  structure gets a valid file->name. The "real" file's name is left
	  uninitialized. This leads to a crash when the progress module hook is called
	  on it.

	grub_net_fs_open() already saved copy of file name as ->net->name, so change
	progress module to use it.

	Also, grub_file_open may leave file->name as NULL if grub_strdup fails. Check
	for it.

	file: ignore host disk in blocklist check
	It cannot work anyway because host disk cannot be read. This fixes hostfs access
	on native Windows build where filenames start with '\' or do not have initial
	separator at all (d:\foo).

	Issue was observed when running grub-fstest on Windows. On UNIX image name is
	canonicalized to always start with `/' so this was not noticed.

	This has side effect of allowing relative path names on host, but this already
	was the case with `ls' command, so it just extends it to all commands.

	makes grub think that we've not sent anything.  So since we have the SNP stuff

	bootp: ignore gateway_ip (relay) field.
	From RFC1542:

	   The 'giaddr' field is rather poorly named.  It exists to facilitate
	   the transfer of BOOTREQUEST messages from a client, through BOOTP
	   relay agents, to servers on different networks than the client.
	   Similarly, it facilitates the delivery of BOOTREPLY messages from the
	   servers, through BOOTP relay agents, back to the client.  In no case
	   does it represent a general IP router to be used by the client.  A
	   BOOTP client MUST set the 'giaddr' field to zero (0.0.0.0) in all
	   BOOTREQUEST messages it generates.

	   A BOOTP client MUST NOT interpret the 'giaddr' field of a BOOTREPLY
	   message to be the IP address of an IP router.  A BOOTP client SHOULD
	   completely ignore the contents of the 'giaddr' field in BOOTREPLY
	   messages.

	Leave code ifdef'd out for the time being in case we see regression.

	efinet: open Simple Network Protocol exclusively
	EDK2 network stack is based on Managed Network Protocol which is layered
	on top of Simple Management Protocol and does background polling. This
	polling races with grub for received (and probably trasmitted) packets
	which causes either serious slowdown or complete failure to load files.

	Open SNP device exclusively.  This destroys all child MNP instances and
	stops background polling.

	Exclusive open cannot be done when enumerating cards, as it would destroy
	PXE information we need to autoconfigure interface; and it cannot be done
	during autoconfiguration as we need to do it for non-PXE boot as well. So
	move SNP open to card ->open method and add matching ->close to clean up.

	Based on patch from Mark Salter <msalter@redhat.com>

	efinet: skip virtual IPv4 and IPv6 devices when enumerating cards
	EDK2 PXE driver creates two child devices - IPv4 and IPv6 - with
	bound SNP instance. This means we get three cards for every physical
	adapter when enumerating. Not only is this confusing, this may result
	in grub ignoring packets that come in via the "wrong" card.

	Example of device hierarchy is

	 Ctrl[91] PciRoot(0x0)/Pci(0x3,0x0)
	   Ctrl[95] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)
	     Ctrl[B4] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv4(0.0.0.0)
	     Ctrl[BC] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv6(0000:0000:0000:0000:0000:0000:0000:0000)

	Skip PXE created virtual devices when enumerating cards. Make sure to
	find real card when applying initial autoconfiguration during PXE boot,
	this information is associated with one of child devices.

	Syslinux memdisk is using initrd image and needs to know uncompressed

	It's not really incompatible as long as driver never writes to FS.

	ext2: Support META_BG.
	This fixes bug that system would become unbootable after ext*
	online resize if no resize_inode was created at ext* format time.

	diskfilter: fix double free of lv names for mdraid
	Avoid micro-optimization in grub_diskfilter_make_raid and make sure
	name and fullname are independent strings. This avoids need to special

	diskfilter: fix crash in validate_lv for mdraid arrays
	Commit 750f4bacd3262376ced3f837d8dc78f834ca233a put LV validation before
	actual vg assignment. Make grub_diskfilter_make_raid to assign ->vg as
	happens in other cases for consistency. Also clean up redundant code and add
	explicit NULL lv->vg check in validate_lv.

	Also fix segment validation in validate_lv; it became obvious when crash
	was fixed.
