of global utent/utxent variables. Only reuse the ut_id and maybe
the ut_host fields from utmp.
* lib/prototypes.h, libmisc/utmp.c: Removed checkutmp(),
setutmp(), setutmpx().
* lib/prototypes.h, libmisc/utmp.c: Added get_current_utmp(),
prepare_utmp(), prepare_utmpx(), setutmp(), setutmpx().
* libmisc/utmp.c (is_my_tty): Only compare the name of the utmp
line with ttyname(). (No stat of the two terminals to compare the
devices).
* libmisc/utmp.c: Use getaddrinfo() to get the address of the
host.
* configure.in: Check for getaddrinfo().
* configure.in: Use AC_CHECK_MEMBERS to check for the existence of
fields in the utmp/utmpx structures.
* configure.in: Reject systems with utmpx support but no ut_id
field in utmp. This could be fixed later if needed.
* src/login.c: Use the new utmp functions. This also simplifies
the failtmp() handling.
* src/login.c: passwd_free() renamed to pw_free() and
shadow_free() renamed to spw_free()
username as first parameter of failtmp to avoid issues with
non-null terminated ut_user, unavailability of ut_user, incomplete
username (that should not happen currently).
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.
never set ifndef USE_PAM. Change the prototype of setup_uid_gid()
when USE_PAM is not defined. This permits to remove add_groups
from PAM builds. setup_uid_gid is already subject to
HAVE_INITGROUPS.
ifndef USE_PAM.
* lib/prototypes.h: Remove the declaration of add_cons_grps(). The
function does not exist.
* libmisc/age.c (setup_uid_gid): is_console is never set ifndef
USE_PAM. Change the prototype of setup_uid_gid() when USE_PAM is
not defined. This permits to remove add_groups from PAM builds.
setup_uid_gid is already subject to HAVE_INITGROUPS.
* libmisc/pwd2spwd.c (pwd_to_spwd): pwd_to_spwd() is not used in
PAM builds.
src/passwd.c, src/pwck.c, src/pwconv.c, src/useradd.c,
src/usermod.c: On Jan 01, 1970, do not set the sp_lstchg field to
0 (which means that the password shall be changed during the next
login), but use -1 (password aging disabled).
* src/passwd.c: Do not check sp_min if sp_lstchg is null or -1.
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.
* src/pwck.c: Only unlock files if they were locked before (e.g.
not in read-only mode).
* src/pwck.c: Quote the username in error messages (harmonization
with other messages).
* libmisc/find_new_gid.c: Fixed typo (s/grp->gr_gid/group_id/).
* libmisc/find_new_gid.c: Likewise.
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.
