	pam_motd: add support for a motd.d directory (#48)
	Add a new feature to pam_motd to allow packages to install their own
	message files in a "motd.d" directory, to be displayed after the primary
	motd.
	
	Add an option motd_d= to specify the location of this directory.
	
	Modify the defaults, in the case where no options are given, to display
	both /etc/motd and /etc/motd.d.
	
	Fixes #47
	
	 * modules/pam_motd/pam_motd.c: add support for motd.d

2017-11-10  Dmitry V. Levin  <ldv@altlinux.org>

	pam_tally2 --reset: avoid creating a missing tallylog file.
	There is no need for pam_tally2 in --reset=0 mode to create a missing
	tallylog file because its absence has the same meaning as its existence
	with the appropriate entry reset.

	This was not a big deal until useradd(8) from shadow suite release 4.5
	started to invoke /sbin/pam_tally2 --reset routinely regardless of PAM
	configuration.

	The positive effect of this change is noticeable when using tools like
	cpio(1) that cannot archive huge sparse files efficiently.

	* modules/pam_tally2/pam_tally2.c [MAIN] (main) <cline_user>: Stat
	cline_filename when cline_reset == 0, exit early if the file is missing.

	pam_unix: Check return value of malloc used for setcred data (#24)

	a syslog message and return an error code.

2016-06-15  Dmitry V. Levin  <ldv@altlinux.org>

	pam_timestamp: fix typo in strncmp usage.
	Before this fix, a typo in check_login_time resulted to ruser and
	struct utmp.ut_user being compared by the first character only,
	which in turn could lead to a too low timestamp value being assigned
	to oldest_login, effectively causing bypass of check_login_time.

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().

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.
	* libpam/Makefile.am (libpam_la_SOURCES): Add it.
	* libpam/include/security/pam_modutil.h (pam_modutil_redirect_fd,
	pam_modutil_sanitize_helper_fds): New declarations.
	* libpam/libpam.map (LIBPAM_MODUTIL_1.1.9): New interface.

	pam_xauth: avoid potential SIGPIPE when writing to xauth process.
	Similar issue in pam_unix was fixed by commit Linux-PAM-0-73~8.

	* modules/pam_xauth/pam_xauth.c (run_coprocess): In the parent process,
	close the read end of input pipe after writing to its write end.

	pam_loginuid: log significant loginuid write errors.
	* modules/pam_loginuid/pam_loginuid.c (set_loginuid): Log those errors
	during /proc/self/loginuid update that are not ignored.

	Fix gratuitous use of strdup and x_strdup.
	There is no need to copy strings passed as arguments to execve,
	the only potentially noticeable effect of using strdup/x_strdup
	would be a malformed argument list in case of memory allocation error.

	Also, x_strdup, being a thin wrapper around strdup, is of no benefit
	when its argument is known to be non-NULL, and should not be used in
	such cases.

	* modules/pam_cracklib/pam_cracklib.c (password_check): Use strdup
	instead of x_strdup, the latter is of no benefit in this case.

	* modules/pam_userdb/pam_userdb.c (user_lookup): Likewise.

	* modules/pam_xauth/pam_xauth.c (run_coprocess): Do not use strdup for
	strings passed as arguments to execv.

	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.
	Compare computed and stored hashes case-sensitively.
	Fixes CVE-2013-7041.

	When misc_conv fails to allocate memory for pam_response array, it
	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,
	forward them to misc_conv.

	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.

	pam_limits: detect and ignore stale utmp entries.
	Original idea by Christopher Hailey

	* modules/pam_limits/pam_limits.c (check_logins): Use kill() to
	detect if pid of the utmp entry is still running and ignore the entry
	if it is not.

	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.

	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.

	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).

2014-01-10  Dmitry V. Levin  <ldv@altlinux.org>

	pam_loginuid: return PAM_IGNORE when /proc/self/loginuid does not exist.
	When /proc/self/loginuid does not exist, return PAM_IGNORE instead of
	PAM_SUCCESS, so that we can distinguish between "loginuid set
	successfully" and "loginuid not set, but this is expected".

	Suggested by Steve Langasek.

	* modules/pam_loginuid/pam_loginuid.c (set_loginuid): Change return
	code semantics: return PAM_SUCCESS on success, PAM_IGNORE when loginuid
	does not exist, PAM_SESSION_ERR in case of any other error.
	(_pam_loginuid): Forward the PAM error code returned by set_loginuid.

	pam_warn: log flags passed to the module (ticket #25)
	* modules/pam_warn/pam_warn.c (log_items): Take "flags" argument and
	log it using pam_syslog.
	(pam_sm_authenticate, pam_sm_setcred, pam_sm_chauthtok,
	pam_sm_acct_mgmt, pam_sm_open_session, pam_sm_close_session): Pass
	"flags" argument to log_items.

	Modernize AM_INIT_AUTOMAKE invocation.
	Before this change, automake complained that two- and three-arguments
	forms of AM_INIT_AUTOMAKE are deprecated.

	* configure.in: Pass PACKAGE and VERSION arguments to AC_INIT instead
	of AM_INIT_AUTOMAKE.

	Fix autoconf warnings.

	* configure.in: Call AC_USE_SYSTEM_EXTENSIONS before LT_INIT.

	pam_securetty: check return value of fgets.

	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.

	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

	pam_unix_session.  This change makes pam_unix configuration consistent
	with other PAM modules.

	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

	the other ones.
