* libmisc/copydir.c: Likewise.

checked as such.

of audit_help_open.
* libmisc/salt.c: Use booleans instead of negating integers.

avoid name clashes (change_user -> changed_user; change_uid ->
changed_uid; access -> requested_access)
- generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
chgpasswd; and also passwd if configured without PAM support).
The number of rounds and number of salt bytes was fixed to their lower
allowed values (resp. configurable and 8), hence voiding some of the
advantages of this encryption method. Dictionary attacks with
precomputed tables were easier than expected, but still harder than with
the MD5 (or DES) methods.
* NEWS, libmisc/salt.c (SHA_salt_size): Seed the RNG, and fix a
overflow. These caused the SHA salt size to always be 8 bytes,
instead of being in the 8-16 range. Thanks to Peter Vrabec
pvrabec@redhat.com for noticing.
* NEWS, libmisc/salt.c (SHA_salt_rounds): Seed the RNG with
seedRNG instead of srand, and fix the same overflow. This caused
the number of rounds to always be the smallest one.
* libmisc/pam_pass.c: Be more verbose and indicate that the
password was not changed when pam_chauthtok fails (in addition to
the PAM error, which may not be comprehensible for the users).
SIGSTOP handling. Raise the signal which stopped the child instead
of always SIGSTOP.
Import Debian patch 406_vipw_resume_properly.
Thanks to Dean Gaudet.

endpwend() sequences (ditto for getgrent(), getspent(), and
getsgent()). The only real (minor) issue was in login, which kept
the passwd file open.
* libmisc/entry.c: Remove unneeded setspent() and endspent() (only
getspnam is called in the middle).
* libmisc/find_new_ids.c: Make sure to close the password and
group files with endpwent() and endgrent().
* libmisc/pwdcheck.c: Remove unneeded endspent() (only getspnam()
is called before).
* src/lastlog.c, src/passwd.c, src/groupmod.c, src/faillog.c,
src/groups.c: Make sure to close
the password file with endpwent().

Better handling of error cases, like locked group or gshadow file.

* src/gpasswd.c (get_group): Do not fail if gshadow is not present. Just use
the group file and set the grent structure
* src/gpasswd.c (check_perms): The permissions should be checked
using both the gshadow and group file. Add a <struct group *>
parameter, and check if the gshadow file exists (is_shadowgrp).
* src/gpasswd.c (main): Do not use sgent.sg_mem or sgent.sg_adm if
the gshadow file is not present (sgent is not initialized in that
case). The fields of sgent can be set, but not used.
Document new variables.
* man/newusers.8.xml, man/login.defs.5.xml,
man/login.defs.d/GID_MAX.xml, man/login.defs.d/UID_MAX.xml:
newusers uses now the GID_MAX, GID_MIN, UID_MAX, UID_MIN,
SYS_GID_MAX, SYS_GID_MIN, SYS_UID_MAX, and SYS_UID_MIN variables.
* man/groupadd.8.xml, man/login.defs.5.xml: groupadd uses now the
SYS_GID_MAX, and SYS_GID_MIN variables.
* man/login.defs.5.xml: useradd uses now the SYS_GID_MAX,
SYS_GID_MIN, SYS_UID_MAX, and SYS_UID_MIN variables.
* src/newusers.c: The user's ID must be found before the group ID
to mimic useradd's behavior choices of UID and GID.
* src/newusers.c: Reuse the generic find_new_uid() and
find_new_gid() functions. This permits to respect the

find_new_uid() and find_new_gid(). They work the same way as the functions
with the same name of useradd or groupadd, except that they check in the
local database to make sure an ID was not reserved in an uncommitted
change (this is needed to be used in newusers), they report a status
instead of calling exit(), and they can receive a preferred ID. They
should later support system IDs. This should be a little bit slower, but
not too much (if the database is not open the checks against the local
database will exit immediately, and if it is already open, all the checks
will be done regarding the data in memory).
