terminates.

constant string. (username).
* src/grpconv.c: At the end of main, the passwd and shadow files
are locked. No need to check before unlocking. No need to set the
lock as false neither since there cannot be anymore failures.
strtoday(). But we need to support "-1" specifically.
* src/chage.c: Fix usage: LOGIN is mandatory.
* src/chage.c: Display disabled expiry or last change as "-1"
instead of 1969-12-31. 1969-12-31 is still supported as input from
the user.

removed).
USER_DEFAULTS_FILE.

* src/useradd.c: Fail, but do not print the usage message when the
-e argument is not valid.

already checked.
save_caller_context() is allocated and freed.
* src/su.c: Added missing #endif indication
* src/su.c save_caller_context(): password only needed if
SU_ACCESS and !USE_PAM.

(will be) added, set the passwd's password to 'x'.
* src/newusers.c: An invalid line is an error. A failure needs to
be reported.
* lib/Makefile.am: Added lib/spawn.c and lib/spawn.h.
* lib/nscd.c, lib/spawn.c, lib/spawn.h: It is not possible to
differentiate between an nscd failure, and a failure to execute
due to no nscd with posix_spawn. Use our own run_command routine.
* src/userdel.c: Use run_command()
* src/usermod.c (date_to_str): buf needs to be unique (e.g.
independent from negativ), and is an out buffer.
* src/usermod.c: Ignore return value from snprintf, and force
nul-termination of buffer.
* src/usermod.c: Improve memory management.

* src/faillog.c: Check that there are no extra arguments after
parsing the options.

* 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.

Avoid checking twice in a row for NULL != list[i].

comments.
* libmisc/find_new_gid.c, libmisc/find_new_uid.c: Be more strict

if the password is changed and passwd requires a shadow entry, or

-e and -f require a shadow file.

* src/usermod.c (process_flags): Check option compatibility and
dependency before options are discarded when no changes are
requested.
* src/su.c: Added function prototypes.
* src/su.c: Rename shellstr parameter to shellname to avoid
collision with static variable.
* NEWS, src/su.c: Added support for PAM modules which change
PAM_USER.

prepare_pam_close_session() is now executed before the creation of
the pam session and before the UID is changed. This allows to
close the session as root.
use the pwent global variable to communicate between APIs of
different files. Added boolean parameter su_to_root to
check_su_auth().
* src/su.c (check_perms): Return the passwd entry of the finally
authenticated user. Remove usage of the pwent variable.
* src/su.c: The password of the caller is the one from the
spwd structure only if the passwd's password is 'x'.
after the switch to the final subsystem. The previous architecture
forced to always change the environment (the shell starts with a
'*' and was thus restricted, and change_environment could not be
reset to false).
definition of shellstr, PATH and IFS is not influenced (getenv,
getdef, restricted_shell) by and does not influence (addenv does
not change environ) the authentication. And the authentication
does not overwrite those definitions. This will ease an extraction
from the big main() function.
commands executed with -c. This prevents tty hijacking which could
lead to execution with the caller's privileges. This required to
forward signals from the terminal (SIGINT, SIGQUIT, SIGTSTP) to
the executed command.
