* Changelog: Update documentation of 2013-07-28 mancha entry.
* lib/prototypes.h, lib/encrypt.c: Update splint marker,
pw_encrypt can return NULL.
* lib/encrypt.c: Fix outdated statement on GNU crypt.
* src/chgpasswd.c: Improve diagnostic to user when pw_encrypt
fails and use fail_exit() instead of exit().
* src/chpasswd.c: Likewise.
* src/newusers.c: Likewise.
* src/passwd.c: Likewise when new password is encrypted.
* src/newgrp.c: Improve diagnostic to user and syslog when
pw_encrypt fails. Do not apply 1s penalty as this is not an
invalid password issue.
* src/passwd.c: Likewise when password is checked.
a salt that violates specs. On Linux, crypt() also fails with
DES/MD5 salts in FIPS140 mode. Rather than exit() on NULL returns
we send them back to the caller for appropriate handling.

src/groupmod.c, src/newusers.c, src/useradd.c, src/userdel.c,
src/usermod.c: Provide the PAM error
message instead of our own, and log error to syslog.
* src/groupmems.c: Exit with exit rather than fail_exit in usage().
* src/newusers.c: Check the number of arguments.
* src/newusers.c: Do not create the home directory when it is not
changed.
* src/useradd.c: Set the group password to "!" rather "x" if there
are no gshadow file.
set to 'x' in passwd and there are no entry in shadow for the
user.
* NEWS, src/chgpasswd.c: Create a gshadow entry if the password is
set to 'x' in group and there are no entry in gshadow for the
group.
not return.
* src/chgpasswd.c: Split usage in smaller parts. Those parts are
already translated for chpasswd. Usage is now closer to
chpasswd's.
* src/chgpasswd.c: Remove dead code. No need to set crypt_method
to NULL when it is already NULL. sflg is only set if crypt_method
is not NULL.

src/faillog.c, src/chsh.c: If someone uses the -h/--help options,
the usage should not go to stderr nor should the utility exit with
non-zero status. All of the shadow utils do just this
unfortunately, so convert them over to sanity.
* man/groupmems.8.xml, man/gpasswd.1.xml: Added option -h/--help.

account management tools: chage, chgpasswd, chpasswd, groupadd,

needed to initialize retval to PAM_SUCCESS.

syslog.

failures to lock or open the databases. This might be harmless,
and the logs were not already informed that a change was
requested.

password.

Daubert for the patch.
* libmisc/salt.c: Include <stdio.h>, needed for stderr and printf
functions.
* lib/encrypt.c: Include <stdio.h>, needed for perror, stderr and
printf functions
* src/usermod.c: sgr_locked exists only if SHADOWGRP is defined.
* src/chgpasswd.c: Only check is the gshadow file exists if
SHADOWGRP is defined.
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
SHA512 if USE_SHA_CRYPT is not defined (this corresponds to a
subset of the ENCRYPTMETHOD_SELECT sections).
Thanks to Dan Kopecek <dkopecek@redhat.com>.
* 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.
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.
