	pam_setquota: skip mountpoints equal to the user's $HOME.
	Matthias Gerstner found the following issue:

	<quote>
	So this pam_setquota module iterates over all mounted file systems using
	`setmntent()` and `getmntent()`.  It tries to find the longest match of
	a file system mounted on /home/$USER or above (except when the
	fs=/some/path parameter is passed to the pam module).

	The thing is that /home/$USER is owned by the unprivileged user.  And
	there exist tools like fusermount from libfuse which is by default
	installed setuid-root for everybody.  fusermount allows to mount a FUSE
	file system using an arbitrary "source device name" as the unprivileged
	user.

	Thus considering the following use case:

	1) there is only the root file system (/) or a file system is mounted on
	   /home, but not on /home/$USER.
	2) the attacker mounts a fake FUSE file system over its own home directory:

	  ```
	  user $ export _FUSE_COMMFD=0
	  user $ fusermount $HOME -ononempty,fsname=/dev/sda1
	  ```

	  This will result in a mount entry in /proc/mounts looking like this:

	  ```
	  /dev/sda1 on /home/$USER type fuse (rw,nosuid,nodev,relatime,user_id=1000,group_id=100)
	  ```
	3) when the attacker now logs in with pam_setquota configured then
	   pam_setquota will identify /dev/sda1 and the file system where
	   to apply the user's quota on.

	As a result an unprivileged user has full control over onto which block
	device the quota is applied.
	</quote>

	If the user's $HOME is on a separate partition, setting a quota on the
	user's $HOME does not really make sense, so this patch skips mountpoints
	equal to the user's $HOME, preventing the above mentioned bug as
	a side-effect (or vice-versa).

	pam_debug: do not invoke pam_get_user and do not set PAM_USER.
	pam_debug used to invoke pam_get_user and set PAM_USER to "nobody" when
	pam_get_user returns an empty string as the user name.  When either of
	these functions returned an error value, it used to return that error
	value.  This hasn't been documented, and I couldn't find any rationale
	for this behaviour.

	* modules/pam_debug/pam_debug.c (pam_sm_authenticate): Do not invoke
	pam_get_user and pam_set_item.

	pam_localuser: forward error values returned by pam_get_user.
	Starting with commit c2c601f5340a59c5c62193d55b555d384380ea38,
	pam_get_user is guaranteed to return one of the following values:
	PAM_SUCCESS, PAM_BUF_ERR, PAM_CONV_AGAIN, or PAM_CONV_ERR.

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Do not
	replace non-PAM_CONV_AGAIN error values returned by pam_get_user with
	PAM_SERVICE_ERR.

	pam_localuser: open the passwd file after user name validation.
	Since user name is untrusted input, it should be validated earlier
	rather than later.

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Open
	the passwd file after user name validation.

2020-05-21  Dmitry V. Levin  <ldv@altlinux.org>

	pam_localuser: use BUFSIZ as the line buffer size.
	As BUFSIZ is the buffer size used in stdio, it must be an efficient size
	for the line buffer.  Also, it's larger than LINE_MAX used as the line
	buffer size before this change, effectively raising the maximum user
	name length supported by this module.

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Replace
	LINE_MAX with BUFSIZ.

2020-05-21  Dmitry V. Levin  <ldv@altlinux.org>

	pam_localuser: handle long lines in passwd files properly.
	Before this change, a long line in the passwd file used to be treated as
	several lines which could potentially result to false match and,
	consequently, to incorrect PAM_SUCCESS return value.

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Handle
	long lines in passwd files properly.

2020-05-21  Dmitry V. Levin  <ldv@altlinux.org>

	unrecognized options.

2020-05-21  Dmitry V. Levin  <ldv@altlinux.org>

	pam_localuser: return PAM_SERVICE_ERR instead of PAM_SYSTEM_ERR.
	When passwd file cannot be opened or the user name either cannot be
	obtained or is not valid, return PAM_SERVICE_ERR instead of
	PAM_SYSTEM_ERR.

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Return
	PAM_SERVICE_ERR instead of PAM_SYSTEM_ERR.

2020-05-21  Dmitry V. Levin  <ldv@altlinux.org>

	pam_localuser: reject user names that are too long.
	Too long user names used to be truncated which could potentially result
	to false match and, consequently, to incorrect PAM_SUCCESS return value.

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Return
	PAM_SERVICE_ERR if the user name is too long.

2020-05-21  Dmitry V. Levin  <ldv@altlinux.org>

	pam_localuser: reject user names containing a colon.
	"root:x" is not a local user name even if the passwd file contains
	a line starting with "root:x:".

	* modules/pam_localuser/pam_localuser.c (pam_sm_authenticate): Return
	PAM_PERM_DENIED if the user name contains a colon.

	doc: fix the description of stack jump effects.
	Every stack jump, besides the jump itself, has a side effect which is
	one of 'ignore', 'ok', or 'bad'.  Unfortunately, the side effect is far
	from obvious because it depends on the PAM function call, and the
	documentation that contradicts the implementation does not help either.

	* doc/man/pam.conf-syntax.xml (actionN): Rewrite the description
	of stack jump effects to match the implementation.

	pam_get_user: do not override valid values returned by the conversation function
	When the conversation function returned a value different from
	PAM_CONV_AGAIN and provided no response, pam_get_user used to replace
	the return value with PAM_CONV_ERR.  Fix this and replace the return
	value only if it was PAM_SUCCESS.

	* libpam/pam_item.c (pam_get_user): Do not override valid values
	returned by the conversation function.

	pam_get_user: filter conversation function return values.
	Do not assume that the conversation function provided by the application
	strictly follows the return values guidelines, replace undocumented
	return values with PAM_CONV_ERR.

	* libpam/pam_item.c (pam_get_user): If the value returned by the
	conversation function is not one of PAM_SUCCESS, PAM_BUF_ERR,
	PAM_CONV_AGAIN, or PAM_CONV_ERR, replace it with PAM_CONV_ERR.

	pam_get_user: consistently return PAM_SYSTEM_ERR if user specified a NULL pointer
	pam_get_user returns PAM_SYSTEM_ERR in case of pamh == NULL.
	In case of user == NULL, however, it used to return PAM_PERM_DENIED,
	and in case of NULL conversation function it used to return
	PAM_SERVICE_ERR.

	According to the documentation, PAM_SYSTEM_ERR shall be returned
	if a NULL pointer was submitted.

	Fix this inconsistency and return PAM_SYSTEM_ERR in each of these
	programming error cases.

	* libpam/pam_item.c (pam_get_user): Return PAM_SYSTEM_ERR instead of
	PAM_PERM_DENIED if user == NULL.  Return PAM_SYSTEM_ERR instead of

	build: rework vendordir substitution.
	Since Make.xml.rules is the only place where XSLTPROC_CUSTOM was used,
	remove stereotypic definitions from other Makefiles, this way we no
	longer have to worry about vendordir being used somewhere else in
	documentation files.

	Likewise, define VENDORDIR in config.h and remove stereotypic
	-DVENDORDIR= additions from other Makefiles, this way we no longer
	have to worry about VENDORDIR being used somewhere else in the code.

	* configure.ac (AM_CONDITIONAL): Remove HAVE_VENDORDIR.
	(AC_DEFINE_UNQUOTED): Add VENDORDIR.

	Since README is also listed in noinst_DATA, we can safely replace
	README in EXTRA_DIST with $(DATA), this also opens the way for

	pam_unix: Return PAM_AUTHINFO_UNAVAIL when appropriate.
	The pam_unix.so will never return PAM_AUTHINFO_UNAVAIL on systems
	that use the unix_chkpwd helper.

	The reason is that in unix_chkpwd.c, towards the end of main(), if
	helper_verify_password() does not return PAM_SUCCESS, main() ignores
	the actual error that helper_verify_password() returned and instead
	returns PAM_AUTH_ERR.

	This commit corrects this behavior.  Specifically, if
	helper_verify_password() returns PAM_USER_UNKNOWN, which it does
	when /etc/passwd entry indicates that shadow information is present
	but the /etc/shadow entry is missing, the unix_chkpwd now exits
	with PAM_AUTHINFO_UNAVAIL. For any other error from
	helper_verify_password(), unix_chkpwd continues to exit with
	PAM_AUTH_ERR.

	* modules/pam_unix/unix_chkpwd.c (main): Return PAM_AUTHINFO_UNAVAIL
	when helper_verify_password() returns PAM_USER_UNKNOWN.

	pam_modutil_sanitize_helper_fds: fix SIGPIPE effect of PAM_MODUTIL_PIPE_FD
	When pam_modutil_sanitize_helper_fds() is invoked with
	PAM_MODUTIL_PIPE_FD to provide a dummy pipe descriptor for stdout
	or stderr, it closes the read end of the newly created dummy pipe.
	The negative side effect of this approach is that any write to such
	descriptor triggers a SIGPIPE.  Avoid this by closing the write end of
	the dummy pipe and using its read end as a dummy pipe descriptor for
	output.  Any read from such descriptor returns 0, and any write just
	fails with EBADF, which should work better with unprepared writers.

	* libpam/pam_modutil_sanitize.c (redirect_out_pipe): Remove.
	(redirect_out): Call redirect_in_pipe instead of redirect_out_pipe.

	Fixes: b0ec5d1e ("Introduce pam_modutil_sanitize_helper_fds")

	pam_namespace: secure tmp-inst directories.
	When using polyinstantiation for /tmp and/or /var/tmp, pam_namespace
	creates subdirectories with fixed name tmp-inst. These paths should be

	could created and controlled by for example a malicious user or

	on its uid. To evaluate the condition it will use 0-99 reserved range
	together with `SYS_UID_MIN` and `SYS_UID_MAX` values from `/etc/login.defs`.

	If these values are not set, it uses configure-time defaults
	`--with-sys-uid-min` and `--with-uid-min` (according to `login.defs` man page
	`SYS_UID_MAX` defaults to `UID_MIN - 1`.

	This information can be used to skip specific module in pam stack
	based on the account type. `pam_succeed_if uid < 1000` is used at the moment
	however it does not reflect changes to `login.defs`.

	Fix remaining -Wcast-qual compilation warnings.
	Introduce a new internal header file with definitions of
	DIAG_PUSH_IGNORE_CAST_QUAL and DIAG_POP_IGNORE_CAST_QUAL macros,
	use them to temporary silence -Wcast-qual compilation warnings
	in various modules.

	* libpam/include/pam_cc_compat.h: New file.

2020-01-17  Björn Esser  <besser82@fedoraproject.org>

	pam_unix: Return NULL instead of calling crypt_md5_wrapper().
	If the call to the crypt(3) function failed for some reason during
	hashing a new login passphrase, the wrapper function for computing
	a hash with the md5crypt method was called internally by the pam_unix
	module in previous versions of linux-pam.

	With CVE-2012-3287 in mind, the md5crypt method is not considered to
	be a safe nor recommended hashing method for a new login passphrase
	since at least 2012.  Thus pam_unix should error out in case of a
	failure in crypt(3) instead of silently computing a hashed passphrase
	using a potentially unsafe method.

	* modules/pam_unix/pam_unix.8.xml: Update documentation.
	* modules/pam_unix/passverify.c (create_password_hash): Return NULL
	on error instead of silently invoke crypt_md5_wrapper().

2020-01-15  Hulto  <jack.m.mckenna@gmail.com>

	Changed variable salt to hash.

	pam_umask: document the 'nousergroups' option.
	Add a short description of the nousergroups to the pam_umask(8)
	man-page.

2020-01-10  Andreas Henriksson  <andreas@fatal.se>

	pam_umask: add new 'nousergroups' module argument.
	This is particularly useful when pam has been built with the new
	--enable-usergroups configure switch, allowing users to override
	the default-enabled state and disabling usergroups at runtime.

	This is synonymous but opposite to current and previous pam_umask
	default that could be changed to enabled at runtime with the usergroups
	argument.

2020-01-10  Andreas Henriksson  <andreas@fatal.se>

	pam_umask: build-time usergroups option default.
	This change adds a configure option to set the default value of the
	usergroups option (of the pam_umask module) at build-time.

	Distributions usually makes the decision if usergroups should be used or
	not. This allows them to control the built-in default value, without
	having to ship the value in a config file (cluttering up the view
	of actually relevant user/system configuration overrides).

	--enable-vendordir defines where Linux-PAM should additional look
	for pam.d/*, login.defs and securetty if this files are not in /etc.
	libeconf is a key/value configuration file reading library, which
	handles the split of configuration files in different locations
	and merges them transparently for the application.

	pam_lastlog: document the 'unlimited' option.

2019-09-12  Carlos Santos  <casantos@redhat.com>

	pam_lastlog: prevent crash due to reduced 'fsize' limit.
	It a reduced fsize limit is set in /etc/security/limits.conf and
	pam_limits is in use pam_lastlog may cause a crash, e.g.

	    ----- begin /etc/pam.d/su ----
	    auth        sufficient   pam_rootok.so
	    auth        required     pam_wheel.so use_uid
	    auth        required     pam_env.so
	    auth        required     pam_unix.so nullok
	    account     required     pam_unix.so
	    password    required     pam_unix.so nullok
	    session     required     pam_limits.so
	    session     required     pam_env.so
	    session     required     pam_unix.so
	    session     optional     pam_lastlog.so
	    ----- end /etc/pam.d/su -----

	    ----- begin /etc/security/limits.d/fsize.conf -----
	    * soft fsize 1710
	    * hard fsize 1710
	    ----- end /etc/security/limits.d/fsize.conf -----

	    # id user1
	    uid=1000(user1) gid=1000(user1) groups=1000(user1)
	    # su - user1
	    Last login: Wed Sep 11 01:52:44 UTC 2019 on console
	    $ exit
	    # id user2
	    uid=60000(user2) gid=60000(user2) groups=60000(user2)
	    # su - user2
	    File size limit exceeded

	This happens because pam_limits sets RLIMIT_FSIZE before pam_lastlog
	attempts to write /var/log/lastlog, leading to a SIGXFSZ signal.

	In order to fix this, and an 'unlimited' option, which leads to saving
	the 'fsize' limit and set it to unlimited before writing lastlog. After
	that, restore the saved value. If 'fsize' is already unlimited nothing
	is done.

	Failing to set the 'fsize' limit is not a fatal error.  With luck the
	configured limit will suffice, so we try to write lastlog anyway, even
	under the risk of dying due to a SIGXFSZ.

	Failing to restore the 'fsize' limit is a fatal error, since we don't
	want to keep it unlimited.

2019-09-02  Matt Cowell  <matt.cowell@nokia.com>

	pwhistory: fix read of uninitialized data and memory leak when modifying opasswd
	The glibc implementation of getline/getdelim does not guarantee a NUL
	terminator in lineptr if getline returns failure (-1).  This occurs when
	the opasswd file exists but is empty.  Since strdup is called
	immediately afterwards, this causes strdup to read uninitialized memory
	and possibly buffer overrun / crash.

	This also fixes a memory leak which always occurs when reading the last
	line of the opasswd file.  Since the strdup is called before checking
	the return code from getline, getdelim, or fgets+strlen, it will
	duplicate and never free either:
	- The last successfully read line (for getline or getdelim)
	- Uninitialized data (if the file is empty)
	- A 0 byte string (for fgets+strlen)

	Fix by always checking the return code of getline, getdelim, or
	fgets+strlen before calling strdup.

	pam_tally2: Remove unnecessary fsync()
	pam_tally2 does fsync() after writing to a tally file.
	This causes hard drive cache flushes on every failed SSH login on many
	(if not most) filesystems.
	And an internet-exposed machine can have a lot of these failed logins.

	This operation however doesn't seem to be necessary - the pam_tally2
	module does not do any operation which would need explicit post-crash
	ordering, it just does simple file reads and writes.
	And doing a fsync() after them doesn't close any race if the system happens
	to crash between a write being posted and its fsync() completion.

	Let's remove this operation to get rid of all these extra cache flushes.

	pam_unix: Report unusable hashes found by checksalt to syslog.
	libxcrypt can be build-time configured to support (or not support)
	various hashing methods.  Future versions will also have support for
	runtime configuration by the system's vendor and/or administrator.

	For that reason adminstrator should be notified by pam if users cannot
	log into their account anymore because of such a change in the system's
	configuration of libxcrypt.

	Also check for malformed hashes, like descrypt hashes starting with
	"$2...", which might have been generated by unsafe base64 encoding
	functions as used in glibc <= 2.16.
	Such hashes are likely to be rejected by many recent implementations
	of libcrypt.

	* modules/pam_unix/passverify.c (verify_pwd_hash): Report unusable

	pam_unix: Add crypt_default method, if supported.
	libxcrypt since v4.4.0 supports a default method for its
	gensalt function on most system configurations.  As the

	methods supported by pam.

	pam_unix: Add support for crypt_checksalt, if libcrypt supports it.
	libxcrypt v4.3 has added the crypt_checksalt function to whether
	the prefix at the begining of a given hash string refers to a
	supported hashing method.

	Future revisions of this function will add support to check whether
	the hashing method, the prefix refers to, was disabled or considered
	deprecated by the system's factory presets or system administrator.
	Furthermore it will be able to detect whether the parameters, which
	are used by the corresponding hashing method, being encoded in the
	hash string are not considered to be strong enough anymore.

	pam_motd: Support multiple motd paths specified, with filename overrides (#69)
	Adds specifying multiple paths to motd files and motd.d
	directories to be displayed. A colon-separated list of
	paths is specified as arguments motd and motd_dir to the
	pam_motd module.
	
	This gives packages several options to install motd files to.
	By default, the paths are, with highest priority first:
	/etc/motd
	/run/motd
	/usr/lib/motd
	/etc/motd.d/
	/run/motd.d/
	/usr/lib/motd.d/
	
	Which is equivalent to the following arguments:
	motd=/etc/motd:/run/motd:/usr/lib/motd
	motd_dir=/etc/motd.d:/run/motd.d:/usr/lib/motd.d
	
	Files with the same filename in a lower-priority directory,
	as specified by the order in the colon-separated list, are
	overridden, meaning PAM will not display them.
	
	This allows a package to contain motd files under
	/usr/lib instead of the host configuration in /etc.
	A service may also write a dynamically generated motd in
	/run/motd.d/ and have PAM display it without needing a
	symlink from /etc/motd.d/ installed.
	
	Closes #68
	
	* modules/pam_motd/pam_motd.8.xml: update documentation
	* modules/pam_motd/pam_motd.c: add specifying multiple motd paths

	pam_unix: Use bcrypt b-variant for computing new hashes.
	Bcrypt hashes used the "$2a$" prefix since 1997.
	However, in 2011 an implementation bug was discovered in bcrypt
	affecting the handling of characters in passphrases with the 8th
	bit set.

	Besides fixing the bug, OpenBSD 5.5 introduced the "$2b$" prefix
	for a behavior that exactly matches crypt_blowfish's "$2y$", and
	the crypt_blowfish implementation supports it as well since v1.1.

	That said new computed bcrypt hashes should use the "$2b$" prefix.

	There is no need for pam_tally2 in --reset=0 mode to create a missing

	This was not a big deal until useradd(8) from shadow suite release 4.5

2015-06-22  Thorsten Kukuk  <kukuk@thkukuk.de>

	Release version 1.2.1.
	Security fix: CVE-2015-3238

	If the process executing pam_sm_authenticate or pam_sm_chauthtok method
	of pam_unix is not privileged enough to check the password, e.g.
	if selinux is enabled, the _unix_run_helper_binary function is called.
	When a long enough password is supplied (16 pages or more, i.e. 65536+
	bytes on a system with 4K pages), this helper function hangs
	indefinitely, blocked in the write(2) call while writing to a blocking
	pipe that has a limited capacity.
	With this fix, the verifiable password length will be limited to
	PAM_MAX_RESP_SIZE bytes (i.e. 512 bytes) for pam_exec and pam_unix.

	* NEWS: Update
	* configure.ac: Bump version

	libpam: Only print "Password change aborted" when it's true.
	pam_get_authtok() may be used any time that a password needs to be entered,
	unlike pam_get_authtok_{no,}verify(), which may only be used when
	changing a password; yet when the user aborts, it prints "Password change
	aborted." whether or not that was the operation being performed.

	This bug was non-obvious because none of the modules distributed with
	Linux-PAM use it for anything but changing passwords; pam_unix has its
	own utility function that it uses instead.  As an example, the
	nss-pam-ldapd package uses it in pam_sm_authenticate().

	libpam/pam_get_authtok.c (pam_get_authtok_internal): check that the
	password is trying to be changed before printing a message about the
	password change being aborted.

2014-01-27  Dmitry V. Levin  <ldv@altlinux.org>

	Introduce pam_modutil_sanitize_helper_fds.
	This change introduces pam_modutil_sanitize_helper_fds - a new function
	that redirects standard descriptors and closes all other descriptors.

	pam_modutil_sanitize_helper_fds supports three types of input and output
	redirection:
	- PAM_MODUTIL_IGNORE_FD: do not redirect at all.
	- PAM_MODUTIL_PIPE_FD: redirect to a pipe.  For stdin, it is implemented
	  by creating a pipe, closing its write end, and redirecting stdin to
	  its read end.  Likewise, for stdout/stderr it is implemented by
	  creating a pipe, closing its read end, and redirecting to its write
	  end.  Unlike stdin redirection, stdout/stderr redirection to a pipe
	  has a side effect that a process writing to such descriptor should be
	  prepared to handle SIGPIPE appropriately.
	- PAM_MODUTIL_NULL_FD: redirect to /dev/null.  For stdin, it is
	  implemented via PAM_MODUTIL_PIPE_FD because there is no functional
	  difference.  For stdout/stderr, it is classic redirection to
	  /dev/null.

	PAM_MODUTIL_PIPE_FD is usually more suitable due to linux kernel
	security restrictions, but when the helper process might be writing to
	the corresponding descriptor and termination of the helper process by
	SIGPIPE is not desirable, one should choose PAM_MODUTIL_NULL_FD.

	* libpam/pam_modutil_sanitize.c: New file.

	There is no need to copy strings passed as arguments to execve,
	the only potentially noticeable effect of using strdup/x_strdup

	pam_userdb: fix password hash comparison.
	Starting with commit Linux-PAM-0-77-28-g0b3e583 that introduced hashed
	passwords support in pam_userdb, hashes are compared case-insensitively.
	This bug leads to accepting hashes for completely different passwords in
	addition to those that should be accepted.

	Additionally, commit Linux-PAM-1_1_6-13-ge2a8187 that added support for
	modern password hashes with different lengths and settings, did not
	update the hash comparison accordingly, which leads to accepting
	computed hashes longer than stored hashes when the latter is a prefix
	of the former.

	* modules/pam_userdb/pam_userdb.c (user_lookup): Reject the computed
	hash whose length differs from the stored hash length.

	returns PAM_CONV_ERR.  However, when read_string fails to allocate
	memory for a response string, it loses the response string and silently
	ignores the error, with net result as if EOF has been read.

	* libpam_misc/misc_conv.c (read_string): Use strdup instead of x_strdup,
	the latter is of no benefit in this case.
	Do not ignore potential memory allocation errors returned by strdup,

	string is expected.

2014-01-20  Dmitry V. Levin  <ldv@altlinux.org>

	pam_mkhomedir: check and create home directory for the same user (ticket #22)
	Before pam_mkhomedir helper was introduced in commit
	7b14630ef39e71f603aeca0c47edf2f384717176, pam_mkhomedir was checking for
	existance and creating the same directory - the home directory of the
	user NAME returned by pam_get_item(PAM_USER).

	The change in behaviour accidentally introduced along with
	mkhomedir_helper is not consistent: while the module still checks for
	getpwnam(NAME)->pw_dir, the directory created by mkhomedir_helper is
	getpwnam(getpwnam(NAME)->pw_name)->pw_dir, which is not necessarily
	the same as the directory being checked.

	This change brings check and creation back in sync, both handling
	getpwnam(NAME)->pw_dir.

	* modules/pam_mkhomedir/pam_mkhomedir.c (create_homedir): Replace
	"struct passwd *" argument with user's name and home directory.
	Pass user's name to MKHOMEDIR_HELPER.
	(pam_sm_open_session): Update create_homedir call.

	if it is not.

2014-01-19  Stéphane Graber  <stgraber@ubuntu.com>

	pam_loginuid: Always return PAM_IGNORE in userns.
	The previous patch to support user namespaces works fine with containers
	that are started from a desktop/terminal session but fails when dealing
	with containers that were started from a remote session such as ssh.

	I haven't looked at the exact reason for that in the kernel but on the
	userspace side of things, the difference is that containers started from
	an ssh session will happily let pam open /proc/self/loginuid read-write,
	will let it read its content but will then fail with EPERM when trying
	to write to it.

	So to make the userns support bullet proof, this commit moves the userns
	check earlier in the function (which means a small performance impact as
	it'll now happen everytime on kernels that have userns support) and will
	set rc = PAM_IGNORE instead of rc = PAM_ERROR.

	The rest of the code is still executed in the event that PAM is run on a
	future kernel where we have some kind of audit namespace that includes a
	working loginuid.

2014-01-15  Steve Langasek  <vorlon@debian.org>

	pam_namespace: don't use bashisms in default namespace.init script.
	* modules/pam_namespace/pam_namespace.c: call setuid() before execing the
	namespace init script, so that scripts run with maximum privilege regardless
	of the shell implementation.
	* modules/pam_namespace/namespace.init: drop the '-p' bashism from the
	shebang line

	This is not a POSIX standard option, it's a bashism.  The bash manpage says
	that it's used to prevent the effective user id from being reset to the real
	user id on startup, and to ignore certain unsafe variables from the
	environment.

	In the case of pam_namespace, the -p is not necessary for environment
	sanitizing because the PAM module (properly) sanitizes the environment
	before execing the script.

	The stated reason given in CVS history for passing -p is to "preserve euid
	when called from setuid apps (su, newrole)."  This should be done more
	portably, by calling setuid() before spawning the shell.

2014-01-10  Stéphane Graber  <stgraber@ubuntu.com>

	pam_loginuid: Ignore failure in user namespaces.
	When running pam_loginuid in a container using the user namespaces, even
	uid 0 isn't allowed to set the loginuid property.

	This change catches the EACCES from opening loginuid, checks if the user
	is in the host namespace (by comparing the uid_map with the host's one)
	and only if that's the case, sets rc to 1.

	Should uid_map not exist or be unreadable for some reason, it'll be
	assumed that the process is running on the host's namespace.

	The initial reason behind this change was failure to ssh into an
	unprivileged container (using a 3.13 kernel and current LXC) when using
	a standard pam profile for sshd (which requires success from
	pam_loginuid).

	I believe this solution doesn't have any drawback and will allow people
	to use unprivileged containers normally. An alternative would be to have
	all distros set pam_loginuid as optional but that'd be bad for any of
	the other potential failure case which people may care about.

	There has also been some discussions to get some of the audit features
	tied with the user namespaces but currently none of that has been merged
	upstream and the currently proposed implementation doesn't cover
	loginuid (nor is it clear how this should even work when loginuid is set
	as immutable after initial write).

	pam_loginuid: return PAM_IGNORE when /proc/self/loginuid does not exist.
	When /proc/self/loginuid does not exist, return PAM_IGNORE instead of

	successfully" and "loginuid not set, but this is expected".

	Suggested by Steve Langasek.

	* modules/pam_loginuid/pam_loginuid.c (set_loginuid): Change return

	/proc
	(sepermit_match): Apply the exclusive check only when loginuid not set.

2013-08-22  Tomas Mraz  <tmraz@fedoraproject.org>

	Updated translations from Transifex.
	* po/*.po: Updated translations from Transifex.

2013-07-01  Dmitry V. Levin  <ldv@altlinux.org>

	pam_rootok: fix linking in --enable-audit mode.
	pam_rootok.c explicitly uses functions from libaudit, so the module has
	to be linked with the library.

	* modules/pam_rootok/Makefile.am (pam_rootok_la_LIBADD): Add @LIBAUDIT@.

2013-07-01  Richard Guy Briggs  <rgb@redhat.com>

	pam_tty_audit: fix a typo that crept in during patch review.
	* modules/pam_tty_audit/pam_tty_audit.c (pam_sm_open_session): Replace
	all occurrences of HAVE_AUDIT_TTY_STATUS_LOG_PASSWD with
	HAVE_STRUCT_AUDIT_TTY_STATUS_LOG_PASSWD.
	* configure.in (HAVE_AUDIT_TTY_STATUS_LOG_PASSWD): Remove.

2013-06-21  Richard Guy Briggs  <rgb@redhat.com>

	pam_tty_audit: add an option to control logging of passwords: log_passwd
	Most commands are entered one line at a time and processed as complete lines
	in non-canonical mode.  Commands that interactively require a password, enter
	canonical mode with echo set to off to do this.  This feature (icanon and
	!echo) can be used to avoid logging passwords by audit while still logging the
	rest of the command.  Adding a member to the struct audit_tty_status passed in
	by pam_tty_audit allows control of logging passwords per task.

	* configure.in: autoconf bits to conditionally add support at compile time
	depending on struct audit_tty_status kernel header version.
	* modules/pam_tty_audit/pam_tty_audit.8.xml: Document new pam_tty_audit module
	log_passwd option.
	* modules/pam_tty_audit/pam_tty_audit.c: (pam_sm_open_session): Added
	"log_passwd" option parsing.

	* modules/pam_unix/support.h: Add define for /etc/login.defs
	* modules/pam_unix/pam_unix.8.xml: Document new behavior.
	* modules/pam_umask/pam_umask.c: Add missing NULL pointer check

2013-04-12  Tomas Mraz  <tmraz@fedoraproject.org>

	pam_access: better not change the default function used to get domain name.
	modules/pam_access/pam_access.c (netgroup_match): As we did not use
	yp_get_default_domain() in the 1.1 branch due to typo in ifdef

	running with real uid == 0.

2012-10-10  Dmitry V. Levin  <ldv@altlinux.org>

	pam_unix: fix build in --enable-selinux mode.
	glibc's <sys/wait.h> starting with commit
	http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=glibc-2.15-231-gd94a467
	does not include <sys/resource.h> for POSIX 2008 conformance reasons, so
	when pam is being built with SELinux support enabled, pam_unix_passwd.c
	uses getrlimit(2) and therefore should include <sys/resource.h> without
	relying on other headers.

	* modules/pam_unix/pam_unix_passwd.c: Include <sys/resource.h>.

2012-02-03  Dmitry V. Levin  <ldv@altlinux.org>

	pam_unix: make configuration consistent in --enable-static-modules mode.
	In --enable-static-modules mode, it was not possible to use "pam_unix"
	in PAM config files.  Instead, different names had to be used for each
	management group: pam_unix_auth, pam_unix_acct, pam_unix_passwd and
	pam_unix_session.  This change makes pam_unix configuration consistent
	with other PAM modules.

	* README: Remove the paragraph describing pam_unix distinctions in
	--enable-static-modules mode.

	Fix SUBDIRS for --enable-static-modules mode.
	There is no way to build "modules" subdirectory before "libpam" anyway.
	In STATIC_MODULES mode, "libpam" subdirectory must be built twice to
	produce a usable libpam.a without undefined references to multiple
	_pam_*_modstruct symbols.

	* Makefile.am: Use default SUBDIRS in STATIC_MODULES mode.

2011-10-28  Dmitry V. Levin  <ldv@altlinux.org>

	Use libpam.la/libpam_misc.la to link with -lpam/-lpam_misc.
	GNU automake documentation recommends to avoid using -l options in
	LDADD or LIBADD when referring to libraries built by the package.
	Instead, it recommends to write the file name of the library explicitly,
	and use -l option only to list third-party libraries.  As result, the
	default value of *_DEPENDENCIES will list all local libraries and omit
	the other ones.
	* modules/pam_access/Makefile.am (pam_access_la_LIBADD): Replace
	"-L$(top_builddir)/libpam -lpam" with
