This was not the case when the GID is not specified, and a GID
exist with an ID higher than the all the UIDs.

prefered_rounds value, if specified.
* src/gpasswd.c, libmisc/salt.c: Fix compilation warnings (use

MD5_CRYPT_ENAB, SHA_CRYPT_MIN_ROUNDS, and SHA_CRYPT_MAX_ROUNDS
variables.
* etc/login.defs: Indicate that MD5_CRYPT_ENAB is deprecated.
Document the relationship with PAM for MD5_CRYPT_ENAB and

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

rounds in case of one of the SHA methods. The new prototype of

shadow-4.0.18.1-sha256.patch. Thanks to Peter Vrabec. Hardly no changes
except re-indent and changes related to recent modifications (max_salt_len
in crypt_make_salt). Changes in lib/defines.h not applied (definition of
ENCRYPTMETHOD_SELECT). I will add a configure check or flag.
* 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/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.
cleanup(2) by spw_unlock and remove the calls to cleanup(1).

patch shadow-4.0.16-nscd.c.
* lib/commonio.c: Forbid inheritance of the passwd and group files
to the spawed processes (like nscd). This comes from the RedHat
patch shadow-4.0.17-notInheritFd.patch.
* lib/nscd.h: Update header.
spw_locked, gr_locked, and sgr_locked to indicate which files must
be unlocked.

group files as well as the passwd files. This permit to check if
the group files modification are allowed before writing the passwd
files.
* src/usermod.c (grp_update, update_gshadow, update_group): Do not
return a status code, but call fail_exit() in case of error. The
group files are no more opened and closed in update_gshadow() and
update_group().
* src/usermod.c (main): move the call to grp_update between
open_files and close_files.
* src/usermod.c: Differentiate failure to add a group entry and
failure to add a shadow group entry.
* NEWS, lib/commonio.c (commonio_update): When an entry is updated, make
sure that there are no other entry with the same name. This fixes
an infinite loop in userdel and usermod when an (erroneous) group
file contains two entries with the same name.

* NEWS, src/chgpasswd.c, src/chpasswd.c: The protocol + salt does
not need 15 chars. No need for a temporary buffer.
This change the fix committed on 2007-11-10. The salt provided to
pw_encrypt could have been too long.
