Subject: [PATCH] libpam: use getlogin() from libc and not utmp
utmp uses 32bit time_t for compatibility with 32bit userland on some
64bit systems and is thus not Y2038 safe. Use getlogin() from libc
which avoids using utmp and is more safe than the old utmp-based
implementation by using /proc/self/loginuid.
* libpam/pam_modutil_getlogin.c: Use getlogin() instead of parsing utmp

Subject: [PATCH 1/2] pam_faillock: fix formatting of audit messages
pam_faillock uses audit_log_user_message to write to the audit system.
It does not take an op argument, so you have to add one yourself. Otherwise
the pam_faillock part of the message is lost because it's not in key=value
format.
Also, we can't use uid in that event because the kernel already adds that
field. What we normally do is use 'suid' (meaning sender uid) as the
field name.

From d54870f993e97fe75e2cd0470a3701d5af22877c Mon Sep 17 00:00:00 2001
From: Changqing Li <changqing.li@windriver.com>
Date: Tue, 12 Jan 2021 14:45:34 +0800
Subject: [PATCH] faillock: create tallydir before creating tallyfile
The default tallydir is "/var/run/faillock", and this default
tallydir may not exist.
Function open may fail as tallydir does not exist when creating
the tallyfile. Therefore, faillock will not work well.
Fix this problem by creating tallydir before creating tallyfile
when the tallydir does not exist.

Subject: [PATCH] pam_namespace: protect_dir(): use O_DIRECTORY to prevent
local DoS situations
Without O_DIRECTORY the path crawling logic is subject to e.g. FIFOs
being placed in user controlled directories, causing the PAM module to
block indefinitely during `openat()`.
Pass O_DIRECTORY to cause the `openat()` to fail if the path does not
refer to a directory.
With this the check whether the final path element is a directory
becomes unnecessary, drop it.

Subject: [PATCH] pam_unix: allow empty passwords with non-empty hashes
Before the change pam_unix has different behaviours for a user with
empty password for these two `/etc/shadow` entries:
nulloktest:$6$Yy4ty2jJ$bsVQWo8qlXC6UHq1/qTC3UR60ZJKmKApJ3Wj7DreAy8FxlVKtlDnplFQ7jMLVlDqordE7e4t49GvTb.aI59TP0:1::::::
nulloktest::1::::::
The entry with a hash was rejected and the entry without was accepted.
The rejection happened because 9e74e90147c "pam_unix: avoid determining
if user exists" introduced the following rejection check (slightly
simplified):
...
} else if (p[0] == '\0' && nullok) {
if (hash[0] != '\0') {
retval = PAM_AUTH_ERR;
}
We should not reject the user with a hash assuming it's non-empty.
The change does that by pushing empty password check into
`verify_pwd_hash()`.
`NixOS` generates such hashed entries for empty passwords as if they
were non-empty using the following perl code:
sub hashPassword {
my ($password) = @_;
my $salt = "";
my @chars = ('.', '/', 0..9, 'A'..'Z', 'a'..'z');
$salt .= $chars[rand 64] for (1..8);
return crypt($password, '$6$' . $salt . '$');
}
Resolves: https://github.com/linux-pam/linux-pam/issues/758
Fixes: 9e74e90147c "pam_unix: avoid determining if user exists"

file descriptor leak as pointed out by the static analyzer tool:

From b3bb13e18a74e9ece825b7de1b81db97ebb107a0 Mon Sep 17 00:00:00 2001
From: Iker Pedrosa <ipedrosa@redhat.com>

Subject: [PATCH] pam_timestamp: replace hmac implementation
sha1 is no longer recommended as a cryptographic algorithm for
authentication. Thus, the idea of this change is to replace the
implementation provided by hmacsha1 included in pam_timestamp module by
the one in the openssl library. This way, there's no need to maintain
the cryptographic algorithm implementation and it can be easily changed
with a single configuration change.
modules/pam_timestamp/hmac_openssl_wrapper.c: implement wrapper
functions around openssl's hmac implementation. Moreover, manage the key
generation and its read and write in a file. Include an option to
configure the cryptographic algorithm in login.defs file.
modules/pam_timestamp/hmac_openssl_wrapper.h: likewise.
modules/pam_timestamp/pam_timestamp.c: replace calls to functions
provided by hmacsha1 by functions provided by openssl's wrapper.
configure.ac: include openssl dependecy if it is enabled.
modules/pam_timestamp/Makefile.am: include new files and openssl library
to compilation.
ci/install-dependencies.sh: include openssl library to dependencies.
NEWS: add new item to next release.
Make.xml.rules.in: add stringparam profiling for hmac
doc/custom-man.xsl: change import docbook to one with profiling
modules/pam_timestamp/pam_timestamp.8.xml: add conditional paragraph to
indicate the value in /etc/login.defs that holds the value for the
encryption algorithm
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1947294
