The get_defaults() has to be called before processing the flags.

358bd9b359 Fix sentence in usermod manual
Should have been: '[...] but only checkS [...]'.
So there was a missing 's'. Architectures isn't the right word either.

dd50014055 Fixed signal races in shadow tools.
Some of the supplied tools use functions which are not signal-safe.

Most of the times it's exit() vs. _exit().

In other times it's how the standard output or standard error is
handled. FILE-related functions shall be avoided, therefore I replaced
them with write().

Also there is no need to call closelog(). At worst, it allows to
trigger a deadlock by issuing different signal types at bad timings.
But as these fixes are about race conditions, expect bad timings in
general for these bugs to be triggered. :)

c07397695a */Makefile.am: Replace INCLUDES with AM_CPPFLAGS
Catch up with Automake's [1], which was part of v1.6b, cut 2002-07-28
[2].  Avoids:

  $ autoreconf -v -f --install
  ...
  libmisc/Makefile.am:4: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
  ...
  src/Makefile.am:10: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')

Consolidating with the earlier AM_CPPFLAGS avoids:

  $ autoreconf -v -f --install

66897b6f6d Add ability to clear or set lastlog record for user via lastlog command
This functionality is useful because there is now a feature
of Linux-PAM's pam_lastlog module to block expired users (users
which did not login recently enough) from login. This commit
complements it so the sysadmin is able to unblock such expired user.

af064545bf useradd: respect -r flag when allocating subuids
We intend to not create subuids for system users. However we are
checking for command line flags after we check whether -r flag
was set, so it was never found to be true.  Fix that.

Tweak uid/gid map default configuration

Tweak uid/gid map default configuration
- Use an allocation of 65536 uids and gids to allow for POSIX-compliant
   user owned namespaces.
 - Don't allocate a uid/gid map to system users.
   Unfortunately checking for --system isn't quite enough as some
   distribution wrappers always call useradd without --system and take care
   of choosing a uid and gid themselves, so also check whether the
   requested uid/gid is in the user range.

This is taken from a patch I wrote for Ubuntu a couple years ago and
which somehow didn't make it upstream.

Don't limit subuid/subgid support to local users

a887847ca2 Don't limit subuid/subgid support to local users
The current implementation of subuid/subgid support in usermod requires the
user to be a local user present in /etc/passwd.  There doesn't seem to be a
good reason for this; subuids should work equally well for users whose
records are in other NSS databases.

c17f5ec460 Free memory on error path
When multiple entries with the same name are encountered, nentry is
not properly freed, which results in a memory leak.

df5dafe049 Clear passwords on __gr_dup/__pw_dup errors.
The functions __gr_dup and __pw_dup do not explicitly zero the
memory which hold the passwords after free. The gr_free and pw_free
functions do this explicitly.

To guarantee same behaviour, it's possible to call these *_free
functions directly from __*_dup, because the memory is initialized
with zeros at the beginning. Calling free(NULL) has no negative
effect and can be considered safe these days.
