* src/chpasswd.c, src/chgpasswd.c: Do not use DES by default, but
the system default define in /Etc/login.defs. Thanks to Dan
Kopecek <dkopecek@redhat.com>.
* NEWS, man/chpasswd.8.xml, man/chgpasswd.8.xml: Do not mention
DES as the default algorithm.
* src/chpasswd.c, src/chgpasswd.c: Tag the ENCRYPTMETHOD_SELECT
dependent code accordingly.
* src/chpasswd.c: Added --sha-rounds to the usage().
* libmisc/Makefile.am, libmisc/getlong.c, src/chgpasswd.c,
src/chpasswd.c: New getlong function. Replace chpasswd's and
chgpasswd's getnumber.

* Use <option> vor the variable names. This
makes the manpage much more readable.
* (ENCRYPT_METHOD, MD5_CRYPT_ENAB,
SHA_CRYPT_MIN_ROUNDS, SHA_CRYPT_MAX_ROUNDS): Mention that command
line option may supersede the system setting.
* Document the variables used by chpasswd
and chgpasswd.
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)
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.
* NEWS: Indicate that manpages should be re-generated if configure
option are changed, due to conditions.
generation of manpages.
* man/generate_translations.mak: Added pam/no_pam condition (like
in man/Makefile.am).
* man/Makefile.am, man/generate_translations.mak: Added
gshadow/no_gshadow condition.
* man/gpasswd.1.xml: Use the gshadow/no_gshadow condition to
change the manpage depending on the shadow group support.
and /etc/passwd to section FILES.
* man/newusers.8.xml: Mentions that PAM is not used to set the
passwords.
* man/chpasswd.8.xml: Added section FILES (/etc/passwd,
/etc/shadow, /etc/login.defs).
* man/chpasswd.8.xml: Use the same paragraph as in newusers.8.xml
to indicate that PAM is not used.
* man/chgpasswd.8.xml: Added section FILES (/etc/group,
/etc/gshadow, /etc/login.defs).
This was not the case when the GID is not specified, and a GID
exist with an ID higher than the all the UIDs.
* Typo in comment: contrained -> constrained.
SHA256, and SHA512 exactly (not only the first 3/6 chars).
* libmisc/salt.c (SHA_salt_rounds): Set rounds to the specified
prefered_rounds value, if specified.
* src/gpasswd.c, libmisc/salt.c: Fix compilation warnings (use
size_t for lengths).
* src/chpasswd.c, src/chgpasswd.c: Add missing parenthesis.
encryption algorithm is chosen for the passwords. Document the new
-c and -s options. Add a reference to login.defs(5).
* man/login.defs.5.xml: Document the ENCRYPT_METHOD,
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
ENCRYPT_METHOD.
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.
bytes).
* lib/getdef.c, etc/login.defs: Add definitions for
SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS.
* libmisc/salt.c: Use SHA_CRYPT_MIN_ROUNDS and SHA_CRYPT_MAX_ROUNDS
to add a random number of rounds if needed.

* libmisc/salt.c (crypt_make_salt): Initialize result[0] to nul at
the beginning (was not initialized when USE_PAM).
* libmisc/salt.c (crypt_make_salt): Check that ENCRYPT_METHOD is a
valid crypt method.
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.
