3935d32676 Mention RedHat's patches for previous commits.
Merge RedHat's patch shadow-4.0.18.1-findNewUidOnce.patch:
	* src/useradd.c (usr_update): Do not call find_new_uid(). The UID was
	already either specified or found by another call to find_new_uid().
	* src/useradd.c (find_new_uid): Always start with uid_min (find_new_uid()
	is never called when user_id was already specified).
	* src/useradd.c (find_new_uid): Fix the comments (find_new_uid() is not
	called when the UID is specified (uflg)).
	* src/useradd.c (main): Only call find_new_uid() if (!oflg) and (!uflg).
	If uflg is set (but not oflg), check the UID uniqueness.
	* src/useradd.c (find_new_uid): Don't check the uid and user name
	uniqueness in find_new_uid(). The user name uniqueness is already checked
	during the parameter validation. UID uniqueness is also checked (see
	above).
	* src/useradd.c (find_new_uid): Don't check uflg in find_new_uid().
	* src/useradd.c (find_new_uid): Make sure that find_new_uid() is not
	called when uflg is set (assert).

Cleanups in find_new_gid:
	* src/useradd.c (find_new_gid): Check that gflg is not set (assert).
	* src/useradd.c (find_new_gid): Do not check the group name uniqueness
	(already checked in main).
	* src/useradd.c (find_new_gid): Avoid a "continue" in the loop.
	* src/useradd.c (find_new_gid): Remove irrelevant comments.
	* src/useradd.c (find_new_gid): Fix the function definition's comment.

4d606cc690 * configure.in: New configure option: --with-sha-crypt enabled by
default. Keeping the feature enabled is safe. Disabling it permits
  to disable the references to the SHA256 and SHA512 password
  encryption algorithms from the usage help and manuals (in addition
  to the support for these algorithms in the code).
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: ENCRYPT_METHOD is
  always supported in login.defs. Remove the ENCRYPTMETHOD_SELECT
  preprocessor condition.
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
  src/chpasswd.c, src/chgpasswd.c, src/passwd.c: Disable SHA256 and

a0488ccac2 * NEWS, src/gpasswd.c: Read the group and shadow groups using
gr_locate and sgr_locate. gpasswd write in the file database. Thus
  it should read information from the file database, not using
  getgrnam. The change to sgr_locate is just for consistency. This
  requires opening the group databases (read only) using
  gr_open/sgr_open.

0b695f5a76 * lib/prototypes.h, libmisc/salt.c: Add parameters to
crypt_make_salt to force the crypt method and number of rounds.
* libmisc/salt.c: Add parameter to SHA_salt_rounds to force the
  number of rounds.
* libmisc/salt.c, lib/getdef.c: ENCRYPT_METHOD and MD5_CRYPT_ENAB
  are needed also when USE_PAM (e.g. for chpasswd).
* src/newusers.c, src/gpasswd.c: Use the new crypt_make_salt prototype.
* src/chpasswd.c, src/chgpasswd.c: Add option -c, --crypt-method
  and -s, --sha-rounds to specify the crypt method and number of
  rounds in case of one of the SHA methods. The new prototype of
  crypt_make_salt simplifies the handling of -m, --md5.

 * 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

  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.
* libmisc/limits.c, libmisc/entry.c, libmisc/chowntty.c,
  libmisc/addgrps.c, libmisc/myname.c, libmisc/rlogin.c,

  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.
