nekral-guest 9c41a8ad38 * libmisc/fields.c: Avoid assignments in comparisons, assignments
with post increments (x++), use of integers as booleans, and
	explicitly mark blocks with brackets.
	* libmisc/copydir.c: Likewise.
	* libmisc/fields.c: Add comments.
	* libmisc/copydir.c: Mark function whose return value is not
	checked as such.

	* libmisc/copydir.c (remove_tree): Make sure unlink is successful
	when removing files.

nekral-guest cda1f9a23d Simply passwd_check since it's never used when configured with PAM support. 2008-05-24 14:11:31 +00:00
nekral-guest 0219d72f48 * libmisc/list.c: Avoid assignments in comparisons, assignments
with post increments (x++), use of integers as booleans, and
	explicitly mark blocks with brackets.

nekral-guest d99423405c Fix compiler warnings:
* libmisc/audit_help.c: Include prototypes.h to get the prototype
	of audit_help_open.
	* libmisc/salt.c: Use booleans instead of negating integers.
	* src/passwd.c: Declare the check_selinux_access prototype and
	avoid name clashes (change_user -> changed_user; change_uid ->
	changed_uid; access -> requested_access)

nekral-guest eeb9592ded Use fputs rather than fprintf for constant strings. 2008-05-23 20:55:11 +00:00
nekral-guest a917ba4fb9 *** security:
- 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.

nekral-guest 3fed00196c Import Debian patch 487_passwd_chauthtok_failed_message
* 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).

nekral-guest c7302b61ef Make sure every source files are distributed with a copyright and license.
Files with no license use the default 3-clauses BSD license. The copyright
were mostly not recorded; they were updated according to the Changelog.
"Julianne Frances Haugh and contributors" changed to "copyright holders
and contributors".

nekral-guest 8a8072a563 If the SULOG_FILE does not exist when an su session is logged, make sure
the file is created with group root, instead of using the group of the
caller.

nekral-guest 4196525702 Allow non-US-ASCII characters in the GECOS fields ("name", "room number",
and "other info" fields).

nekral-guest 2542732a0c Fix ident. 2008-04-16 22:03:43 +00:00
nekral-guest 7baffa5e74 Ensure that getpwent() is used in setpwent(), getpwent(),
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().
* src/login.c: Remove unneeded setpwent() (only xgetpwnam is
  called before).
* src/login.c, src/newgrp.c: Fix typos in comments.

nekral-guest ca2636f08a Re-indent. 2008-02-19 21:02:24 +00:00
nekral-guest 18c914f086 Added new option -r, --system for system accounts in useradd, groupadd,
and newusers.
2008-02-19 21:01:38 +00:00
nekral-guest 65ed10d75c Do not seed the random number generator each time, and use the time in
microseconds to avoid having the same salt for different passwords
generated in the same second.  This permits to avoid using the same salt
for different passwords in newusers.
2008-02-03 17:23:58 +00:00
nekral-guest aed929ae90 Add libmisc/find_new_ids.c to the sources of the libmisc library. 2008-02-03 16:57:21 +00:00
nekral-guest e21f90fd68 Add new generic functions to find the next user or group ID available:
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).
2008-02-03 16:53:07 +00:00
nekral-guest 57f713e426 * libmisc/age.c, libmisc/yesno.c, src/lastlog.c, src/grpck.c,
src/chfn.c, src/passwd.c, src/chage.c, src/login.c, src/sulogin.c,

 * po/*.po: Unfuzzy PO files according to above change.
2008-02-03 16:28:03 +00:00
nekral-guest ae99674e9b Fix build failures with --disable-shadowgrp. Thanks to Jürgen
Daubert for the patch.
* libmisc/salt.c: Include <stdio.h>, needed for stderr and printf
  functions.
* lib/encrypt.c: Include <stdio.h>, needed for perror, stderr and
  printf functions
* src/usermod.c: sgr_locked exists only if SHADOWGRP is defined.
* src/chgpasswd.c: Only check is the gshadow file exists if
  SHADOWGRP is defined.
2008-01-26 17:41:20 +00:00
nekral-guest 28a9441f4f Replace printf by puts for fixed strings. This would avoid issues caused
by formats introduced in translated strings.

  const. (ditto for the method variable).
* libmisc/salt.c: SHA_salt_rounds returns a const string.

* libmisc/salt.c: Replace rand() by random().

2008-01-05 16:44:28 +00:00

2008-01-05 16:33:43 +00:00
nekral-guest 5a4848c8cc do_pam_passwd should not have been defined static, prototypes.h needed
to be included instead.

nekral-guest b681e50ff2 * libmisc/copydir.c, src/usermod.c, lib/prototypes.h: The uid and

nekral-guest dfb6416a5b libmisc/copydir.c cleanup
* 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.
