terminal termio flags. Reset echoprt, noflsh, tostop. This
behavior seems to have change by mistake in earlier releases
(4.0.8, for no obvious reason).
SELinux user for user's login.
* NEWS, src/usermod.c, man/usermod.8.xml: Likewise.
* libmisc/system.c, libmisc/Makefile.am, lib/prototypes.h: Added
safe_system(). Used to run semanage.
* lib/prototypes.h, libmisc/copydir.c: Make a
selinux_file_context() an extern function.
* libmisc/copydir.c: Reset SELinux to create files with default
contexts at the end of copy_tree().
* NEWS, src/userdel.c: Delete the SELinux user mapping for user's
login.
database before calling spw_remove().
* NEWS, src/userdel.c: When the user's group is removed, make sure
the group is in the gshadow database before calling sgr_remove().
* src/userdel.c: Improve warning's wording.
users with -u.
* src/faillog.c: Do not call print_one() for users which do not
exist.
* src/faillog.c: Make sure the user's entry is not outside the
faillog file and initialize the faillog structure in that case.
* src/faillog.c: Move print_one() closer to print().
* src/faillog.c: reset(), setmax(), set_locktime() can also change
entries of user which do not exist.
* src/faillog.c: reset(), setmax() and set_locktime() shall not
create entries for users which have no entries if the value has to
be set to 0.
* src/faillog.c: reset(), setmax() and set_locktime(): better
handling of users whose entry is outside the faillog file.
* src/faillog.c: Improved option handling. Options can now be
specified in any order.
* src/faillog.c: Improved warnings when options are not
compatible or when the faillog cannot be open with the right mode.
* src/faillog.c: Only fstat the faillog file once.
* man/faillog.8.xml: Improved documentation.
when the changes are committed to the system. Do not log failure
for on-memory changes to audit or syslog. Make sure failures and
inconsistencies will be reported in case of unexpected failures
(e.g. malloc failures). Only specify an audit message if it is not
implicitly implied by the type argument. Removed fail_exit
(replaced by atexit(do_cleanups)). Log failures in case of
permission denied.
messages not related to an account.
* lib/prototypes.h, libmisc/cleanup.c, libmisc/cleanup_group.c,
libmisc/cleanup_user.c, libmisc/Makefile.am: Added stack of
cleanup functions to be executed on exit.
* NEWS, src/groupadd.c, src/groupdel.c, src/groupmod.c: Only
report success to audit and syslog when the changes are committed
to the system. Do not log failure for on-memory changes to audit
or syslog. Make sure failures and inconsistencies will be reported
in case of unexpected failures (e.g. malloc failures). Only
specify an audit message if it is not implicitly implied by the
type argument. Removed fail_exit (replaced by atexit(do_cleanups)).
configure option. The configure behavior encoded is:
<no option> -> default of 16 (like today);
--with-group-name-max-length -> default of 16;
--without-group-name-max-length -> no max length;
--with-group-name-max-length=n > max is set to n.
utmp.c to chowntty.c. checkutmp() now only uses an existing utmp
entry if the pid matches and ut_line matches with the current tty.
This fixes a possible DOS when entries can be forged in the utmp
file.
* libmisc/chowntty.c, src/login.c, lib/prototypes.h: Remove the
tty argument from chown_tty. chown_tty always changes stdin and
does not need this argument anymore.
to create a home directory for new users.
* src/useradd.c, man/useradd.8.xml: New -M/--no-create-home option
and CREATE_HOME usage. System accounts are not impacted by
CREATE_HOME.
* man/useradd.8.xml: Indicate that a new group is created by
default.
* src/useradd.c: Removed TODO item (moved to the TODO file).
Thanks to Peter Vrabec.
* NEWS, libmisc/find_new_gid.c, libmisc/find_new_uid.c: Build an
index of used IDs to avoid a database request for each id in the
allowed range (when the highest allowed ID is already used).
This speedups the addition of users or groups when the highest
allowed ID is already used. The additional memory usage of the
tools should be acceptable when UID_MAX/SYS_UID_MAX are set to a
reasonable number.
--disable-account-tools-setuid options. This permits to disable
the PAM authentication of the caller for chage, chgpasswd,
chpasswd, groupadd, groupdel, groupmod, newusers, useradd,
userdel, and usermod. This authentication is not necessary when
these tools are not installed setuid root.
changes have started to be reported to syslog.
* src/userdel.c: Fix some result parameters sent to
audit_logger().
* NEWS: Following changes from a patch contributed by Steve Grubb
<sgrubb@redhat.com>
* src/groupadd.c: Log to audit with type AUDIT_ADD_GROUP instead
of AUDIT_USER_CHAUTHTOK.
* src/groupdel.c: Log to audit with type AUDIT_DEL_GROUP instead
of AUDIT_USER_CHAUTHTOK.
* src/useradd.c: Log to audit with type AUDIT_ADD_USER /
AUDIT_ADD_GROUP / AUDIT_USYS_CONFIG instead of
AUDIT_USER_CHAUTHTOK.
* src/useradd.c: Add missing logs to audit.
* src/userdel.c: Log to audit with type AUDIT_DEL_USER /
AUDIT_DEL_GROUP instead of AUDIT_USER_CHAUTHTOK.
* src/userdel.c: Add missing logs to audit.
* configure.in, libmisc/copydir.c: futimes() and lutimes() are not
standard. Check if they are implemented before using them. Do not
set the time of links if lutimes() does not exist, and use
utimes() as a replacement for futimes().
the list, not adduser. This fixes a segmentation fault for every
call of groupmems -d.
* libmisc/list.c: Add assertions to help identifying these issues.
* libmisc/list.c: Avoid implicit conversion of pointers to
booleans.
support for long options --add (-a), --delete (-d),
--remove-password (-r), --restrict (-R), --administrators (-A),
and --members (-M)
* man/gpasswd.1.xml: Document the new long options.
* src/gpasswd.c: The sgrp structure is only used if SHADOWGRP is
defined.
the --lock an --unlock options do not lock or unlock the user
account anymore. They only lock or unlock the user's password.
* man/passwd.1.xml: Document above change. Document how an account
can be locked and what a password lock means.
* src/groupmems.c: members() renamed display_members() to
avoid name clash with its members argument.
* src/groupmems.c: Report failure to unlock to syslog.
* src/groupmems.c: Harmonize error messages.
* src/groupmems.c: Report failures to write the new group file to
syslog (gr_close() failure).
* src/groupmems.c: Don't use fail_exit for non-failure exit.
* src/groupmems.c: Added Prog global variable to indicate the name
of the program in error messages.

* NEWS, src/groupmems.c: Check if the user added to group actually
exist. RedHat bug #455603
* NEWS, src/groupmems.c: Check if the group exists in the group
local database (/etc/group). RedHat bug #456088
effects. This avoid checking if the user exists in the local passwd
file if not necessary, and thus allow to add LDAP users to local
groups. (The user is already checked against the system
configuration with getpwnam()). Thanks to Dan Kopecek.
* src/newusers.c: Use a bool when possible instead of int
integers.
* src/newusers.c: Avoid implicit conversion of pointers / integers
/ chars to booleans.
* src/newusers.c: Ignore the return value of pam_end() before
exiting.
* src/newusers.c: Ignore return value of setlocale(),
bindtextdomain(), and textdomain().
* src/newusers.c: Avoid multi-statements lines.
* src/newusers.c: Add brackets and parenthesis.
- 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.
