- 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.

to mimic useradd's behavior choices of UID and GID.

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).

* src/lastlog.c: (option -u) user needs to be a signed long, not
uid_t (to accept rangees like -<uid>
gid parameters can be set to -1 to indicate that the original
owners must be kept. Change the types from uid_t/gid_t to a

get_old_fields(), and check_fields() split out of main().
* Before pam_end(), the return value of the previous
pam API was already checked. No need to validate it again.
* src/chage.c: New function: fail_exit(). Change most of the exit()
to a fail_exit, which makes sure the files are unlocked (new global
variables: pw_locked, spw_locked), the PAM transaction is ended, and
the failure is logged to libaudit (use a global user_name and user_uid
for logging).
* src/chage.c: Compilation fix for PAM support (pamh needs to be
global since the function split).

writing. This fix chage when the user only has a password entry (and
no shadow entries).

behavior of the account for the fields that are not specified when the
user has no shadow entry.

pam API was already checked. No need to validate it again.
* src/chage.c: main() split in new functions: process_flags(),
check_flags(), check_perms(), open_files(), and close_files().
* libmisc/copydir.c: Split copy_tree() in more maintainable functions:
copy_entry(), copy_dir(), copy_symlink(), copy_hardlink(),
copy_special(), and copy_file().
* libmisc/copydir.c: -1 is used to indicate an error, directly set err
to -1, instead of incrementing it, and checking if not nul at the
end.
* NEWS, libmisc/setupenv.c: Export PATH according to ENV_PATH and
ENV_SUPATH, as for su. This impacts login.
* man/login.1.xml: PATH and SUPATH are now used both when PAM support
is disabled and enabled.
* libmisc/Makefile.am, lib/prototypes.h, libmisc/yesno.c, src/grpck.c,
src/pwck.c: move yes_or_no() from grpck/pwck to a separate
libmisc/yesno.c (with a read_only argument).

reading the user's answer.
* NEWS: Document that usermod will now preserve user's file modification
and access time.
* libmisc/copydir.c: Preserve the access and modification time of copied
files. This is important for usermod. This will also impact useradd, for
the skeleton files, but this is not important.
* libmisc/copydir.c: Stop and return an error if a file could not be
closed after during a copy.
Merge RedHat's patch shadow-4.0.18.1-findNewUidOnce.patch:
* src/useradd.c (usr_update): Do not call find_new_uid(). The UID was
already either specified or found by another call to find_new_uid().
* src/useradd.c (find_new_uid): Always start with uid_min (find_new_uid()
is never called when user_id was already specified).
* src/useradd.c (find_new_uid): Fix the comments (find_new_uid() is not
called when the UID is specified (uflg)).
* src/useradd.c (main): Only call find_new_uid() if (!oflg) and (!uflg).
If uflg is set (but not oflg), check the UID uniqueness.
* src/useradd.c (find_new_uid): Don't check the uid and user name
uniqueness in find_new_uid(). The user name uniqueness is already checked
during the parameter validation. UID uniqueness is also checked (see
above).
* src/useradd.c (find_new_uid): Don't check uflg in find_new_uid().
* src/useradd.c (find_new_uid): Make sure that find_new_uid() is not
called when uflg is set (assert).
Cleanups in find_new_gid:

* man/login.1.xml: ENV_HZ ENV_PATH ENV_SUPATH MAIL_DIR UMASK are
only used when login is not compiled with PAM support.
man/po/POTFILES.in, man/Makefile.am: Generate the PO files for the
manpages in the man/po directory (instead of man/<lang>). Use a
Makefile.in.in based on gettext's one. This ensure that the PO are
generated before being used in the <lang> directories.
* man/generate_mans.mak, man/generate_translations.mak,
man/Makefile.am: New makefile for the generation of manpages from

* libmisc/tz.c: Use "TZ=CST6CDT" as the default timezone.
libmisc/xgetXXbyYY.c, libmisc/xgetpwnam.c, libmisc/xgetpwuid.c,
libmisc/xgetgrnam.c, libmisc/xgetgrgid.c, libmisc/xgetspnam.c:
Added functions xgetpwnam(), xgetpwuid(), xgetgrnam(),
xgetgrgid(), and xgetspnam(). They allocate memory for the
returned structure and are more robust to successive calls. They
are implemented with the libc's getxxyyy_r() functions if
available.

src/faillog.c, src/groups.c, src/chsh.c, src/id.c: Review all the
usage of one of the getpwnam(), getpwuid(), getgrnam(),
getgrgid(), and getspnam() functions. It was noticed on
http://bugs.debian.org/341230 that chfn and chsh use a passwd
structure after calling a pam function, which result in using
information from the passwd structure requested by pam, not the
original one. It is much easier to use the new xget... functions
to avoid these issues. I've checked which call to the original
get... functions could be left (reducing the scope of the
structure if possible), and I've left comments to ease future
reviews (e.g. /* local, no need for xgetpwnam */).
Note: the getpwent/getgrent calls should probably be checked also.
* src/groupdel.c, src/expiry.c: Fix typos in comments.
* src/groupmod.c: Re-indent.
* libmisc/Makefile.am, lib/groupmem.c, lib/groupio.c, lib/pwmem.c,
lib/pwio.c, lib/shadowmem.c, lib/shadowio.c: Move the __<xx>_dup
functions (used by the xget... functions) from the <xx>io.c files
to the new <xx>mem.c files. This avoid linking some utils against
the SELinux library.
cleanup(2) by spw_unlock and remove the calls to cleanup(1).
* src/chage.c: Remove variable pwrw. It is always set to 0. The
password database is always read only.
generated translated manpages (if ENABLE_REGENERATE_MAN).
* man/Makefile.am: Removed rules for all the generated translated
manpages.
* man/sv/Makefile.am, man/de/Makefile.am, man/fr/Makefile.am,
man/pl/Makefile.am, man/ru/Makefile.am, man/it/Makefile.am:
Include generate_translations.mak to handle the generated
translations (XML and roff files).
* man/Makefile.am: Translated XML files moved from the CLEANFILES
variable of man/Makefile.am to the various languages Makefiles.
* man/useradd.8.xml: Indicate that the NIS caveats is also valid
for any external database as LDAP.
* man/groupadd.8.xml: Likewise.
* man/groupadd.8.xml: Reorder and reformat the caveats bullets.
