0d9799de04 Don't test for NULL before calling free(3)
free(3) accepts NULL, since the oldest ISO C.  I guess the
paranoid code was taking care of prehistoric implementations of
free(3).  I've never known of an implementation that doesn't
conform to this, so let's simplify this.

Remove xfree(3), which was effectively an equivalent of free(3).

408b8a5482 Use the lckpwdf() again if prefix is not set
The implementation of prefix option dropped the use of lckpwdf().
However that is incorrect as other tools manipulating the shadow passwords
such as PAM use lckpwdf() and do not know anything about the
shadow's own locking mechanism.

This reverts the implementation to use lckpwdf() if prefix option
is not used.

0d66002c95 Do not allocate more than necessary
Review b10cba0e0a and 7a16f4582d:
	* lib/groupio.c (merge_group_entries): Do not allocate more than
	necessary (sizeof char* instead of char).
	Thanks for Tomáš Mráz (alioth#313962)
	* lib/groupio.c (merge_group_entries): Document that new_members
	is correctly NULL terminated. (alioth:#313940)

Align previous ChangeLog entries.

	* src/useradd.c: Report failures to unlock files (stderr, syslog,
	and audit). But do not fail (continue).
	* src/useradd.c (open_files): Do not report to syslog & audit
	failures to lock or open the databases. This might be harmless,
	and the logs were not already informed that a change was
	requested.
	* src/usermod.c: It's not the account which is unlocked, but its
	password.

* src/chgpasswd.c: Only check is the gshadow file exists if
  SHADOWGRP is defined.

e15fbb905c * NEWS, lib/getdef.c, man/login.defs.5.xml: New login.defs
variable: MAX_MEMBERS_PER_GROUP. Used for the split groups support.
* lib/commonio.c, lib/commonio.h: Add an open_hook and close_hook
  operation. They are called after the database is actually opened
  and parse, or before it is closed.
* lib/groupio.c: Add an open_hook to merge split groups, and an
  close group to split groups if MAX_MEMBERS_PER_GROUP is set.
  This fixes gpasswd and chgpasswd when split groups are used.
* lib/sgroupio.c, lib/shadowio.c, lib/pwio.c: No open or close
  hooks for these databases. (unsure about what should be the gshadow
  behavior for split groups)

39e5c0a1ab Fix some compilation warnings:
* src/login.c: "dereferencing type-punned pointer will break
   strict-aliasing rules", add a variable indirection: ptr_pam_user.
 * lib/commonio.c: do not initialize the sb stat structure.
 * lib/pwio.c, lib/shadowio.c, lib/sgroupio.c, lib/groupio.c:
   initialize the security context if WITH_SELINUX.
 * lib/nscd.c: The service argument is not const (used in the exec*
   parameters). This matches with the prototype definition.
 * src/groupmems.c: Avoid ++i when i is also used in the same line.
 * src/newusers.c: i is positive every time it is compared. Add
   cast to unsigned int.
 * src/nologin.c: Use a main() prototype with no arguments.
 * libmisc/getdate.y: Initialize the type and value fields of the
   terminating entry for each TABLE.
 * libmisc/tz.c: Use "TZ=CST6CDT" as the default timezone.

libmisc/xgetXXbyYY.c, libmisc/xgetpwnam.c, libmisc/xgetpwuid.c,
  libmisc/xgetgrnam.c, libmisc/xgetgrgid.c, libmisc/xgetspnam.c:
  Added functions xgetpwnam(), xgetpwuid(), xgetgrnam(),
  xgetgrgid(), and xgetspnam(). They allocate memory for the
  returned structure and are more robust to successive calls. They
  are implemented with the libc's getxxyyy_r() functions if
  available.

  src/groupadd.c, src/chage.c, src/login.c, src/suauth.c,
  src/faillog.c, src/groups.c, src/chsh.c, src/id.c: Review all the
  usage of one of the getpwnam(), getpwuid(), getgrnam(),
  getgrgid(), and getspnam() functions. It was noticed on
  http://bugs.debian.org/341230 that chfn and chsh use a passwd
  structure after calling a pam function, which result in using
  information from the passwd structure requested by pam, not the
  original one. It is much easier to use the new xget... functions
  to avoid these issues. I've checked which call to the original
  get... functions could be left (reducing the scope of the
  structure if possible), and I've left comments to ease future
  reviews (e.g. /* local, no need for xgetpwnam */).
  Note: the getpwent/getgrent calls should probably be checked also.
* src/groupdel.c, src/expiry.c: Fix typos in comments.
* src/groupmod.c: Re-indent.
* libmisc/Makefile.am, lib/groupmem.c, lib/groupio.c, lib/pwmem.c,
  lib/pwio.c, lib/shadowmem.c, lib/shadowio.c: Move the __<xx>_dup
  functions (used by the xget... functions) from the <xx>io.c files
  to the new <xx>mem.c files. This avoid linking some utils against
  the SELinux library.
