This is a fork of gentoo's sys-libs/pam package. The main reasons
for having our fork seem to be:
1. We add a locked account functionality. If the account in
`/etc/shadow` has an exclamation mark (`!`) as a first character in
the password field, then the account is blocked.
2. We install configuration in `/usr/lib/pam`, so the configuration in
`/etc` provided by administration can override the config we
install.
3. For an unknown reason we drop `gen_usr_ldscript -a pam pam_misc
pamc` from the recipe.
4. We make the `/sbin/unix_chkpwd` binary a suid one instead of
overriding giving it a CAP_DAC_OVERRIDE to avoid a dependency loop
between pam and libcap. The binary needs to be able to read
/etc/shadow, so either suid or CAP_DAC_OVERRIDE capability should
work. A suid binary is strictly less secure than capability
override, so in long-term we would prefer to avoid having this
hack. On the other hand - this is what we had so far.

Subject: [PATCH] pam_lastlog: fix compilation warning on some of 32-bit
architectures
On those of 32-bit architectures where glibc defines
__WORDSIZE_TIME64_COMPAT32, struct utmp.ut_tv.tv_sec is unsigned,
while time_t is signed, causing the following compiler diagnostics:
pam_lastlog.c: In function 'last_login_failed':
pam_lastlog.c:572:29: warning: comparison of integer expressions of different signedness: '__uint32_t' {aka 'unsigned int'} and 'time_t' {aka 'long int'} [-Wsign-compare]
572 | if (ut.ut_tv.tv_sec >= lltime && strncmp(ut.ut_user, user, UT_NAMESIZE) == 0) {
Given that by its nature these values are treated as unsigned, fix this
by zero-extending both values to unsigned long long before the comparison.
