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
* modules/pam_motd/pam_motd.8.xml: update the manpage

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_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.

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
* modules/pam_exec/pam_exec.8.xml: document limitation of password length

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().

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.

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

when its argument is known to be non-NULL, and should not be used in
such cases.

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.

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.

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).

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.

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>.

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.

_pam_unix_auth_modstruct, _pam_unix_passwd_modstruct,

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.
