3 shadow-4.1.5.1 -> shadow-4.2 UNRELEASED
6 * Handle libc whose crypt() returns NULL when passed a salt that
7 violates specs or system requirements (e.g. FIPS140). This is needed
8 with glibc/eglibc 2.17 for tools checking passwords (passwd (non PAM
9 enabled) or newgrp), and for tools generating encrypted passwords
10 (chgpasswd, chpasswd, or gpasswd when non PAM enabled or when a fixed
11 crypt method is requested on the command line, and newusers, or passwd
12 in their non PAM enabled versions)
13 * Fix segfault when reading groups split on multiple lines. This impacts
14 most user/group management tools when MAX_MEMBERS_PER_GROUP is set.
17 * When su receives a signal (SIGTERM, or SIGINT/SIGQUIT in non
18 interactive mode), kill the child process group, rather than just the

57 * su -c could be abused by the executed command to invoke commands with
58 the caller privileges. See below. (CVE-2005-4890)
61 * report usage error to stderr, but report usage help to stdout (and return
62 zero) when explicitly requested (e.g. with --help).
63 * initial support for tcb (http://openwall.com/tcb/) for useradd,
64 userdel, usermod, chage, pwck, vipw.

66 Support shall be enabled with the new --with-acl or --with-attr
68 * Added diagnosis for lock failures.
69 * use libsemanage instead of the semanage tool.
76 * When the gshadow file exists but there are no gshadow entries, an entry
77 is created if the password is changed and group requires a
81 * PAM enabled versions: restore the -e option to allow restoring
82 passwords without knowing those passwords. Restore together the -m
83 and -c options. (These options were removed in shadow-4.1.4 on PAM
85 * When the shadow file exists but there are no shadow entries, an entry
86 is created if the password is changed and passwd requires a
92 * The -l, -m, -r, -t options only act on the existing users, unless -a is

121 * Added support for infinite limits and group based limits (non PAM
122 enabled versions only)
123 * Fixed infinite loop when CONSOLE is configured with a colon-separated
125 * Fixed warning and support for CONSOLE_GROUPS for users member of more
127 * Do not log into utmp(x) or wtmp when PAM is enabled. This is done by
130 * Fix parsing of gshadow entries.
136 * NIS entries were dropped by -s (sort).
143 * If the skeleton directory contained hardlinked files, copies of the
144 hardlink were removed from the skeleton directory.
147 * Check the existence of the user's mail spool before trying to remove
148 it. If it does not exist, a warning is issued, but no failure.
149 * Do not remove a group with the same name as the user (usergroup) if
150 this group isn't the user's primary group.
152 * Add --selinux-user option.
154 * Accept options in any order (username not necessarily at the end)
155 * When the shadow file exists but there are no shadow entries, an entry
156 is created if the password is changed and passwd requires a
157 shadow entry, or if aging features are used (-e or -f).
160 * Document the su exit values.
161 * When su receives a signal, wait for the child to terminate (after
162 sending a SIGTERM), and kill it only if it did not terminate by itself.
163 No delay will be enforced if the child cooperates.
164 * Default ENV_SUPATH is /sbin:/bin:/usr/sbin:/usr/bin
165 * Fixed infinite loop when CONSOLE is configured with a colon-separated
167 * Fixed warning and support for CONSOLE_GROUPS for users member of more

198 shadow-4.1.4.2 -> shadow-4.1.4.3 2011-02-15
201 - CVE-2011-0721: An insufficient input sanitation in chfn can be exploited
202 to create users or groups in a NIS environment.
204 shadow-4.1.4.1 -> shadow-4.1.4.2 2009-07-24
207 * Improved support for large groups (impacts most user/group management
210 - addition of system users or groups
211 * Speed improvement. This should be noticeable in case of LDAP configured
212 systems. This should impact useradd, groupadd, and newusers
213 * Since system accounts are allocated from SYS_?ID_MIN to SYS_?ID_MAX in
214 reverse order, accounts are packed close to SYS_?ID_MAX if SYS_?ID_MIN
215 is already used but there are still dome gaps.
218 * Add support for shells being a shell script without a shebang.
220 * Preserve the DISPLAY and XAUTHORITY environment variables. This was
221 only the case in the non PAM enabled versions.
222 * Add support for shells being a shell script without a shebang.
225 * The Finnish translation of passwd(1) was outdated and is no more
228 shadow-4.1.4 -> shadow-4.1.4.1 2009-05-22
231 * Fix failures with empty usernames on non PAM versions.
232 * Fix CONSOLE (securetty) support on non PAM versions.
234 * Return the exit status of the child.

237 the user is running some processes.
238 * If not on Linux, continue to search for an utmp record, but make sure
239 the process recorded in the utmp entry is still running.
240 * Report failures to remove the user's mailbox
241 * When USERGROUPS_ENAB is enabled, remove the user's group when the
242 user was the only member.
243 * Do not fail when -r is used and the home directory does not exist.
245 * Check if the user is busy when the user's UID, name or home directory
248 shadow-4.1.3.1 -> shadow-4.1.4 2009-05-10
251 * Enable --enable-account-tools-setuid by default for PAM builds.
252 * Add configure option --enable-utmpx, disabled by default to mimic
253 the previous behavior on Linux (where utmp and utmpx are identical).
254 * Fix build failure on non-PAM systems when --without-pam is not
258 * Change the passwords using PAM. This permits to define the password
259 policy in a central place. The -c/--crypt-method, -e/--encrypted,
260 -m/--md5 and -s/--sha-rounds options are no more supported on PAM
263 * Warn if a group has an entry in group and gshadow, and the password
264 field in group is not 'x'.
266 * Do not trust the current utmp entry's ut_line to set PAM_TTY. This could
268 * (PAM) Even if the user was already authenticated (-f flag), ask the
269 user to update his authentication token if needed.
271 * Fix regression causing empty reports.
273 * Change the passwords using PAM. This permits to define the password
274 policy in a central place. The -c/--crypt-method and -s/--sha-rounds
275 options are no more supported on PAM enabled systems.
277 * Warn if an user has an entry in passwd and shadow, and the password
278 field in passwd is not 'x'.
281 - Updated Czech translation
282 - Updated French translation
283 - Updated German translation
284 - Updated Japanese translation
285 - Updated Korean translation
286 - Updated Portuguese translation
287 - Updated Russian translation
289 shadow-4.1.3 -> shadow-4.1.3.1 2009-04-15
292 - Due to bad parsing of octal permissions, the permissions on tty (login)
293 but also UMASK were set wrongly (and weirdly). Only shadow-4.1.3 was
298 * Fix regression when no user is specified on the command line.
300 * Fixed SE Linux support
302 * SE Linux: Set the default context to the context of the file being
303 edited. This ensures that the backup file inherit from the file's
307 - Updated Norwegian Bokmål translation
309 shadow-4.1.2.2 -> shadow-4.1.3 2009-04-12
313 * Fixed support for OpenPAM.
314 * Fixed support for uclibc.
315 * Added configure --enable-account-tools-setuid (default) /
316 --disable-account-tools-setuid options. This permits to disable the
317 PAM authentication of the caller for chage, chgpasswd, chpasswd,
318 groupadd, groupdel, groupmod, newusers, useradd, userdel, and usermod.
319 This authentication is not necessary when these tools are not
320 installed setuid root.
321 * Added configure --with-group-name-max-length (default) /
322 --without-group-name-max-length options. This permits to configure the maximum length allowed for group names:
323 <no option> -> default of 16 (like today)
324 --with-group-name-max-length -> default of 16
325 --without-group-name-max-length -> no max length
326 --with-group-name-max-length=n > max is set to n
327 No sanity checking is performed on n so people could do
328 something neat like --with-group-name-max-length=MAX_INT
329 - addition of users or groups
330 * Speed improvement in case UID_MAX/SYS_UID_MAX/GID_MAX/SYS_GID_MAX is
331 used for an user/group. This should be noticeable in case of LDAP
332 configured systems. This should impact useradd, groupadd, and newusers
333 - error handling improvement
334 * Make sure errors and incomplete changes are reported to syslog and
335 audit in case of unexpected failures.
336 * Report system inconsistencies to syslog and audit.
337 * Only report success to syslog and audit if the changes are really
338 performed in the system databases.
339 This is still not complete.
341 * New CREATE_HOME variable to tell useradd to create a home directory by
344 * New Kazakh translation.
345 * Spanish manpages are no more distributed. They are outdated. Please
346 contact pkg-shadow-devel@lists.alioth.debian.org if you wish to
350 * Accept users specified as a numerical UID, or ranges of users (-user,
352 * -l, -m, and -r now apply not only to existing users, but to all the
354 * Options can be specified in any order.
356 * Added support for long options --add (-a), --delete (-d),
357 --remove-password (-r), --restrict (-R), --administrators (-A), and
359 * Added support for usernames with arbitrary length.
360 * audit logging improvements.
361 * error handling improvement (see above).
362 * Log permission denied to syslog and audit.
364 * audit logging improvements.
365 * error handling improvement (see above).
366 * Speedup (see "addition of users or groups" above).
367 * do not create groups with GID set to (gid_t)-1.
368 * Allocate system group GIDs in reverse order. This could be useful
369 later to increase the static IDs range.
371 * audit logging improvements.
372 * error handling improvement (see above).
374 * Check if user exist before they are added to groups.
375 * Avoid segfault in case the specified group does not exist in /etc/group.
376 * Everybody is allowed to list the users of a group.
377 * /etc/group is open readonly when one just wants to list the users of a
379 * Added syslog support.
380 * Use the groupmems PAM service name instead of groupmod.
381 * Fix segmentation faults when adding or removing users from a group.
382 * Added support for shadow groups.
383 * Added support long options --add (-a), --delete (-d), --purge (-p),
384 --list (-l), --group (-g).
386 * audit logging improvements.
387 * error handling improvement (see above).
388 * do not create groups with GID set to (gid_t)-1.
390 * warn for groups with GID set to (gid_t)-1.
392 * Restore the echoctl, echoke, onclr flags to the terminal termio flags.
393 Reset echoprt, noflsh, tostop. This behavior seems to have change by
394 mistake in earlier releases (4.0.8, for no obvious reason).
396 * Implement the -r, --system option.
397 * Speedup (see "addition of users or groups" above).
398 * do not create users with UID set to (gid_t)-1.
399 * do not create groups with GID set to (gid_t)-1.
400 * Allocate system account UIDs/GIDs in reverse order. This could be useful
401 later to increase the static IDs range.
403 * For compatibility with other passwd version, the --lock an --unlock
404 options do not lock or unlock the user account anymore. They only
405 lock or unlock the user's password.
407 * warn for users with UID set to (uid_t)-1.
409 * Preserve COLORTERM in addition to TERM when su is called with the -l
412 * audit logging improvements.
413 * Speedup (see "addition of users or groups" above).
414 * See CREATE_HOME above.
415 * New -M/--no-create-home option to disable CREATE_HOME.
416 * do not create users with UID set to (gid_t)-1.
417 * Added -Z option to map SELinux user for user's login.
418 * Allocate system user UIDs in reverse order. This could be useful
419 later to increase the static IDs range.
421 * audit logging improvements.
422 * Do not fail if the removed user is not in the shadow database.
423 * When the user's group shall be removed, do not fail if this group is
424 not in the gshadow file.
425 * Delete the SELinux user mapping for user's login.
427 * Allow adding LDAP users (or any user not present in the local passwd
428 file) to local groups
429 * do not create users with UID set to (gid_t)-1.
430 * Added -Z option to map SELinux user for user's login.
432 shadow-4.1.2.1 -> shadow-4.1.2.2 23-11-2008
435 - Fix a race condition in login that could lead to gaining ownership or
436 changing mode of arbitrary files.
437 - Fix a possible login DOS, which could be caused by injecting forged
440 shadow-4.1.2 -> shadow-4.1.2.1 26-06-2008
443 - Fix an "audit log injection" vulnerability in login.
444 This vulnerability makes it easier for attackers to hide activities by
445 modifying portions of log events, e.g. by appending an addr= statement
448 shadow-4.1.1 -> shadow-4.1.2 25-05-2008
451 - generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
452 chgpasswd; and also passwd if configured without PAM support).
453 The number of rounds and number of salt bytes was fixed to their lower
454 allowed values (resp. configurable and 8), hence voiding some of the
455 advantages of this encryption method. Dictionary attacks with
456 precomputed tables were easier than expected, but still harder than with
457 the MD5 (or DES) methods.
461 * Distribute the chfn, chsh, and userdel PAM configuration file.
462 * Fix the detection of the audit, pam, and selinux library and header
463 file; and fail if the feature is requested but not present on the
465 * Fix build failure when configured with audit support.
467 * Allow non-US-ASCII characters in the GECOS fields ("name", "room
468 number", and "other info" fields).
470 * Do not fail if a shell option, specified after --, has more than 2
473 * If the SULOG_FILE does not exist when an su session is logged, make
474 sure the file is created with group root, instead of using the group
477 * Resume properly after ^Z.
480 - Document the -r, --system option in the useradd, groupadd, and newusers
482 - Document the -c, --crypt-method and -s, --sha-rounds options in the
484 - Document the -k, --skel option in the useradd manpage.
485 - Tag the section which require --enable-shadowgrp or --with-sha-crypt
488 shadow-4.1.0 -> shadow-4.1.1 02-04-2008
492 * Do not seed the random number generator each time, and use the time in
493 microseconds to avoid having the same salt for different passwords
494 generated in the same second.
496 * Do not install the shadow library per default.
498 * Do not translate the messages sent to syslog. This avoids logging
499 PAM error messages in the users's locale.
501 * Set GID_MIN to the same value as UID_MIN by default (1000).
502 * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
503 SYS_GID_MAX (999) for system accounts.
505 * /etc/default/useradd now defines HOME as /home to match FHS.
507 * Fix bug which forbid to set the aging information of an account with a
508 passwd entry, but no shadow entry.
510 * faillog -r now only reset the entries of existing users. This makes
513 * Fix failures when the gshadow file is not present.
514 * When a password is moved to the gshadow file, use "x" instead of "!"
515 to indicate that the password is shadowed (consistency with grpconv).
516 * Make sure the group and gshadow files are unlocked on exit.
518 * New option -p/--password to specify an encrypted password.
519 * New option -r, --system for system accounts.
521 * Do not fail if the group does not exist in the gshadow file.
522 * Do not rewrite the group or gshadow file in case of error.
523 * Make sure the group and gshadow files are unlocked on exit.
524 * Fail if the system is not configured to support split groups and
525 different group entries have the name of the group to be deleted.
527 * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
529 * New option -p/--password to specify an encrypted password.
530 * Make sure the group and gshadow files are unlocked on exit.
531 * When the GID of a group is changed, update also the GID of the passwd
532 entries of the users whose primary group is the group being modified.
534 * Fix logging of changes to syslog when a group file is provided,
535 without a gshadow file.
537 * Accept users specified as a numerical UID, or ranges of users (-user,
540 * Use PATH and SUPATH to set the PATH environment variable, even when
541 support for PAM is enabled.
542 * If started as init, start a new session.
544 * Fix segfault when an user returns to an unknown GID (either the user
545 was deleted during the user's newgrp session or the user's passwd
546 entry referenced an invalid group). Add a syslog warning in that case.
547 * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
548 changing the user space group ID with newgrp or sg.
550 * The new users are no more added to the list of members of their groups
551 because the membership is already set by their primary group.
552 * Added support for gshadow.
553 * Avoid using the same salt for different passwords.
554 * Fix support for the NONE crypt method.
555 * newusers will behave more like useradd regarding the choice of UID or
556 GID or regarding the validity of user and group names.
557 * New option -r, --system for system accounts.
558 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
561 * Make sure that no more than one username argument was provided.
562 * Make SE Linux tests more strict, when the real UID is 0 SE Linux
563 checks will be performed.
565 * Fix logging of changes to syslog when a passwd file is provided,
566 without a shadow file.
568 * su's arguments are now reordered. If needed, use -- to separate su's
569 options from the shell's options.
571 * If started as init, start a new session.
573 * New option -l to avoid adding the user to the lastlog and faillog databases.
574 * Fix the handling of the --defaults option (it required an argument,
575 but should behave as -D)
576 * Document the --defaults option, which was already described in the
577 useradd's Usage information.
578 * New option -r, --system for system accounts.
579 * New options -U, --user-group and -N, --no-user-group. These options
580 should replace nflg from the previous versions. Please set any -n
581 option to deprecated because its meaning differs from one distribution
583 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
586 * Keep the access and modification time of files when moving an user's home
588 * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
589 differ from the old ones. If a requested new value is equal to the old
590 one, no changes will be performed for that field. If no fields are
591 changed, usermod will exist successfully with a warning. This avoids
592 logging changes to syslog when there are actually no changes.
593 * Fix the handling of -a when a user is being renamed (with -l)
595 * Recommend editing the shadowed (resp. regular) file if the regular (resp.
596 shadowed) file was edited.
598 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2007
602 When compiled with PAM support, it used the chpasswd policy file instead
603 of the chgpasswd policy file. If an administrator added some restriction
604 to the chgpasswd policy file, they were not taken into account.
607 - Add support for SHA256 and SHA512 encrypt methods (supported by new
609 - useradd: Allow non numerical group identifier to be specified with
611 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
612 - newgrp: Do not give an indication that the group has no password. Ask
613 for the password, as if there were a password.
614 - The permissions of the suid binaries is now configurable in
615 src/Makefile.am. Note that changing the permissions is not recommended.
616 - newgrp.c: Declare the child and pid variable at the beginning of a block.
617 This fixes a compilation issue with gcc 2.95.
618 - login_nopam: Add support for systems with no innetgr(). On those
619 systems, username with an @ will be treated like any other username
620 (i.e. lookup in the local database for an user with an @). Thanks to
621 Mike Frysinger for the patch.
622 - Add support for uClibc with no l64a().
623 - userdel, usermod: Fix infinite loop caused by erroneous group file
624 containing two entries with the same name. (The fix strategy differs
626 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
627 - userdel: Abort if an error is detected while updating the passwd or group
628 databases. The passwd or group files will not be written.
629 - usermod: Update the group database before flushing the nscd caches.
630 - usermod: Make sure the group modifications will be allowed before
631 writing the passwd files.
632 - Flush the nscd tables using nscd -i instead of the private glibc socket.
633 - usermod: Make usermod options independent of the argument order.
634 - newgrp: Do not request a password when a user uses newgrp to switch to
636 - passwd: -l/-u options: edit the shadow account expiry field *in
637 addition* to editing the password field.
638 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
640 - su: Avoid terminating the PAM library in the forked child. This is done
641 later in the parent after closing the PAM session.
642 - userdel: Fix the homedir prefix checking.
643 - passwd, usermod: Refuse to unlock an account when it would result in a
644 passwordless account.
645 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
646 getgrgid(), and getspnam(). There should be no functional changes.
647 - gpasswd: Only read information from the local file group database. It
648 writes the changes in /etc/group and/or /etc/gshadow, but used to read
649 information from getgrnam (hence possibly from another group database).
650 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
651 better support for split groups. Be careful when using this variable:
652 not all tools support well split groups (in or out of the shadow
653 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
654 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
655 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
657 - chpasswd, chgpasswd, newusers: New options -c/--crypt-method and

1061 - updated translations: sv.
1063 shadow-4.0.10 -> shadow-4.0.11 18-07-2005
1066 - su: ignore SIGINT while authenticating. A ^C could defeat the waiting period and
1067 permit brute-force attacks. Also ignore SIGQUIT.
1068 Fixed: http://bugs.debian.org/52372 and http://bugs.debian.org/288827
1069 - useradd: rewritten for use getopt_long(),
1070 - newgrp: add fix for handle splitted NIS groups: extends the functionality that,

1072 membership of the requesting user.
1073 (fix by Christian Mudra <C.Mudra@science-computing.de>)
1074 - fix nscd_flush_cache(): for some reason doing the INVALIDATE call with two

1076 http://bugs.gentoo.org/show_bug.cgi?id=80413
1077 (submited by Martin Schlemmer <azarah@gentoo.org>)
1078 - merge nscd-socket-path patch from Fedora: newer glibc's have a different nscd socket

1080 - S/Key support is back,
1081 - usermod: added -a option. This flag can only be used in conjunction with the -G

1084 - chage: added missing \n in error messages,
1085 - useradd, groupadd: change -O option to -K and document it in man page,

1090 -- remove --with{,out}-libcrypt switch,
1091 -- move all autoheader templates from acconfig.h to configure.in,
1092 - login: setup limits and umask (using login.defs ULIMITS and UMASK variables) only when
1093 PAM support is disabled (it is task for pam_limits and pam_umask modules),
1094 - sulogin, login: use SYSLOG macro instead syslog() which saves the locale, sets the
1095 locale to C, sends the message and restores the locale
1096 (fix by Nicolas François <nicolas.francois@centraliens.net>).
1097 - updated translations: cs, da, de, es, fi, pl, pt, ro, ru, sk.

1117 - usermod: when relocating a user's home directory, don't fail and remove the new
1118 home directory if we can't remove the old home directory for some
1119 reason; the results can be spectacularly poor if, for instance, only
1120 the rmdir() fails. Patch prepared by Timo Lindfors <lindi-spamtrap@newmail.com>.
1121 http://bugs.debian.org/166369
1122 - su: fix syslogs to be less ambiguous. Use old:new format instead of old-new
1123 because '-' can appear in usernames
1124 http://bugs.debian.org/213592
1125 - removed not used now libmisc/setup.c,
1126 - login: use also UTMPX API instead UTMP on failure (login was affected for this
1127 when shadow was built without PAM support)
1128 patch by Nicolas François <nicolas.francois@centraliens.net>
1129 - login: the PAM session needs to be closed as root, thus before change_uid()
1130 http://bugs.debian.org/53570 http://bugs.debian.org/195048 http://bugs.debian.org/211884
1131 - login: made login's -f option also able to use the username after -- if none
1132 was passed as it's optarg

1134 - login: check for hushed login and pass PAM_SILENT if true,
1135 http://bugs.debian.org/48002
1136 - login: fixed username on successful login (was using the normal username,
1137 when it should have used pam_user) http://bugs.debian.org/47819

1140 - chage: rewritten for use getopt_long(),
1141 - updated translations: ca, cs, da, fi, pl, ru, zh_TW.
1143 - most of the man pages now are generated from XML files so in case submitting any
1144 chages to this resources please make diff to XML files,
1145 - chfn: give more details about the influence of login.defs on what's allowed to
1148 shadow-4.0.8 -> shadow-4.0.9 23-05-2005
1151 - passwd: fixed segfault in non-PAM configuration

1164 - remove not working OPIE and SKEY support,
1165 - chage, useradd, usermod: reduce multiple OPENLOG() calls,

1168 - vipw: fixed race condition (Debian #242407 bug; fix by Alexander Gattin
1169 <arg@online.com.ua>),

1172 - faillog: changed faillog record display format for allow fit in 80 columns all
1174 - removed NDBM code (unused),
1175 - fixed use of SU_WHEEL_ONLY in su. Now su really is available for wheel group

1177 http://bugs.gentoo.org/show_bug.cgi?id=80345
1178 - drop never finished kerberos and des_rpc support (for kerberos support back firs

1186 - useradd: fixes a potential security problem when mailbox is created in
1188 Patch and comment by Koblinger Egmont <egmont@uhulinux.hu>:
1189 Only two arguments are passed to the open() call though it expects three
1190 because O_CREAT is present. Hence the permission of the file first becomes
1191 some random garbage found on the stack, and an attacker can perhaps open
1192 this file and hold it open for reading or writing before the proper
1193 fchmod() is executed. (Actually, we could also pass the final "mode" to
1194 the open() call and then save the consequent fchmod().)
1195 - SELinux changes: added changes in chage, chfn, chsh, passwd for allow
1196 construct more grained user password/account properties on SELinux
1197 policies level. Patch originally based on RH changes (submited by Chris

1232 -- rewritten source code using the same style as in chpasswd.c,
1233 -- open lastlog file after finish parse commandline options
1234 (now --help output can be displayed for users without lastlog
1235 file read permission),
1236 -- cleanups in lastlog(8) man page using the same style as in
1239 -- switch chpasswd to use getopt_long() and adds a --md5 option

1257 - change libmisc to private static library,
1258 - added SELinux support (basing on patch from Gentoo),
1259 - chage: more verbose/human readable -l output. This output is much more

1261 status (for example as message with warning about account/password expiration),
1262 - login: fixed handle -f option: now it works correctly without specify "-h
1263 <host>" if open login session locally is required (thanks for help
1264 investigate bug for Krzysztof Kotlenga),
1265 - userdel: when removing a user with userdel, userdel was always exits with 1 (fixed).
1266 Based on http://bugs.gentoo.org/show_bug.cgi?id=66687,

1274 makes httpd Option SymlinkIfOwnerMatch break for default weg pages
1275 including symlinks placed into /etc/skel/public_html for example.
1276 http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=66819

1363 changes for syncing this are welcome and for anyone who will want maintain
1364 this documents directly I can give cvs write access to project resources.
1365 - added new de translation (by Frank Schmid <frank@cs-schmid.de>).

1392 shadow-4.0.0-owl-chage-ro-no-lock.diff:
1393 Added locks which are needed when doing r/w accesses, not when running

1395 "#include <errno.h>" for above (me).
1396 shadow-4.0.0-owl-warnings.diff
1397 Olny one fix from this patch was applied because other was fixed few days
1399 shadow-4.0.0-owl-check_names.diff

1402 probably _POSIX_LOGIN_NAME_MAX from <bits/posix1_lim.h>,
1403 shadow-4.0.0-owl-chage-drop-priv.diff
1404 shadow-4.0.0-owl-pam-auth.diff
1405 Merge part with reorder initialize PAM and checking if chage is runed by

1422 - fix bug discovered and fixed by Marcel Ritter
1423 <Marcel.Ritter@rrze.uni-erlangen.de>
1424 Due to a big buffer size in lib/commonio.c this error does only appear
1425 if a line gets longer than 4096 bytes (there are probably very few people
1426 stumbling across this).
1427 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
1432 while [ $NUM -le 1000 ]; do
1433 useradd -g demogroup -G demogroup -p "NONE" user$NUM
1436 - remove limit 32 to groups per user by (the same user can belong to
1437 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
1438 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
1439 NOTE: it probably need testing on other system for add
1440 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
1441 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
1442 - drop detecting is pam_strerror() need one or two arguments. Instead using
1443 PAM_STRERROR() macro use directly pam_strerror() function with two
1444 arguments. pam_strerror() with one argument is obsoleted,
1445 - adde ja man pages (probably some man pages need update),
1446 - much better automake support,
1447 - added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
1448 groupmod(8), shadow(5) (man pages for other nations also are welcome),
1449 - many small fixes and updates nad improvements in man pages,
1450 - applied Debian patch to man pages for shadowconfig,
1451 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
1454 shadow-20001012 -> shadow-20001016:
1455 - conditionally disabled body reload_nscd() because not every
1456 version of nscd can handle it (this can be enabled by define
1457 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
1458 - fixes on autoconf/automake level for dist target,
1459 - Julianne F. Haugh new contact address.
1461 shadow-20000902 => shadow-20001012
1463 - removed /redhat directory with obsoleted files (partially rewritten spec
1464 file is now in root directory),
1465 - applied shadow-19990827-group.patch patch from RH wich prevents adduser
1466 overwrite previously existing groups in adduser,
1467 - added PAM support for chage (bind to "chage" PAM config file) also
1468 added PAM support for all other small tools like chpasswd, groupadd,
1469 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
1470 "shadow" PAM config file) - this modifications mainly based on
1471 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
1472 - many small fixes and improvements in automake (mow "make dist"
1474 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
1476 shadow-20000826 => shadow-20000902
1478 This is probably the last release from me.
1479 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
1482 (I'm still interested to know what is going on with this package,
1483 which is fairly important to many Linux distributions, so please
1484 Cc: marekm@linux.org.pl in any related discussions - just don't
1485 expect me to respond quickly...)
1487 Previous warning still applies - be careful!
1489 - applied some of the Red Hat patches (revised slightly), thanks to
1490 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
1491 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
1492 in glibc 2.1.x) after changing anything, add usermod -L and -U
1493 options, remove LOG_CONS from openlog(), chage -d and -E handles
1494 dates in yyyy-mm-dd format ('/' is not required)
1497 shadow-19990827 => shadow-20000826
1499 WARNING: this release is not tested (other than that it compiles for me),
1500 please be careful. Previous release was a year ago, so it is really time
1501 to release something and start looking for a new, better maintainer...
1502 (I've been extremely busy recently. Credit for most of the real work,
1503 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1504 who maintains this package for Debian.)
1506 - merged most of the changes from Debian (not all of them yet, PAM support
1507 should be complete but is not tested - need to upgrade to potato first)
1508 - added Polish translations of manual pages from PLD
1509 - change sulog() to not depend on global variables oldname, name
1510 - try to not follow symbolic links when deleting files recursively
1511 in userdel (still not perfect, safest to do it in single user mode)
1512 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
1513 (a few ANSI C constructs were used already, and no one complained)
1514 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
1516 shadow-19990709 => shadow-19990827
1518 - upgrade to autoconf-2.13, automake-1.4, libtool-1.3.3
1519 - i18n: added French translation by Vincent Renardias <vincent@ldsol.com>
1520 - i18n: added Swedish translation by Kristoffer Brånemyr <ztion@swipnet.se>
1521 - logoutd no longer reads /etc/logoutd.mesg at startup - instead, read
1522 it when sending to luser's tty (no need to reload with SIGHUP)
1523 - added support for "usergroups" feature often found in Linux distributions
1524 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1525 username == groupname, then set umask to 002 instead of 022)
1526 - Debian: pwck and grpck are now run from a daily cron job (root will
1527 receive an e-mail if something is wrong), and at system startup
1528 - added support for setting umask in /etc/limits
1529 - when using OPIE, re-prompt with echo on after empty password was entered
1530 - GETPASS_ASTERISKS now run time configurable (login.defs)
1531 - getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
1532 - getpass() allows all input to be erased using Control-U, and beeps when
1533 too many characters are entered
1534 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1535 - Debian: tar wrapper no longer needed to build packages as non-root user
1536 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1537 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1538 dpkg-architecture, cross compilation, only build passwd, add
1539 etc/login.defs.hurd conffile, conditionalize CBAUD
1540 - newgrp sets $HOME before running the new shell
1541 - both "sg group command" (usage message) and "sg group -c command"
1542 (man page) work, updated both the usage message and the man page :)
1543 - i18n: added missing _() for some translatable strings
1545 shadow-19990607 => shadow-19990709
1547 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
1548 - fixed a bug in newgrp if the user is in >= 17 groups
1549 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1550 almost all programs need it if skey/opie support is enabled)
1551 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1552 - changed faillog to do something (assume -p) with no options specified
1553 - updated version of the udbachk passwd/shadow/group file integrity
1554 checker (contrib/udbachk.v012.tgz)
1556 shadow-19990307 => shadow-19990607
1558 - upgraded to libtool-1.2, latest config.{guess,sub}
1559 - added missing #include "defines.h" in libmisc/login_desrpc.c - thanks
1560 to almost everyone for reporting it :-)
1561 - moved PAM-related defines to pam_defs.h
1562 - added some braces to if/else to avoid egcs warnings
1563 - started adding PAM support to login (based on util-linux, not finished yet)
1564 - changed "!" to "x" for pw_passwd in src/newusers.c
1565 - a few more Y2K fixes
1566 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
1567 thanks to Sami Kerola
1568 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1569 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1570 - updated mailing list information (moved again, now hosted by SuSE),
1571 updated README.mirrors, other minor documentation updates
1572 - made getpass work with redirected stdin
1573 - new readpass echoing asterisks disabled by default by popular demand
1574 (can be enabled at compile time: ./configure --enable-readpass)
1575 - the random number of asterisks in readpass is now more random
1576 (random number generator initialization was missing)
1577 - commented out --enable-md5crypt (obsolete) in configure.in
1578 - when checking for libskey, link with -lcrypt if libcrypt is available
1579 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1580 - added Package/Version ident strings (so you can use the RCS "ident"
1581 command to check any binary, which version of shadow it comes from)
1583 shadow-981228 => shadow-19990307
1585 - added support for setting process priority in /etc/limits
1586 - i18n: updated Greek translation
1587 - i18n: added Polish translation by Arkadiusz Miskiewicz
1588 - documented the -p option in useradd.8 and usermod.8 man pages
1589 - some "const" gcc warning fixes
1590 - attempt to fix lib/snprintf.c compilation problems
1591 - added restart/reload/force-reload to /etc/init.d/logoutd (found by lintian)
1592 - always require password for root logins (even with NO_PASSWORD_CONSOLE)
1593 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1594 - changed to Y2K compatible version numbering
1595 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1596 values of user-entered dates (you can still enter dates in any format
1597 supported by GNU date)
1598 - oops, added doc/README.nls to list of files to distribute
1599 - added missing sanitize_env() call to src/login.c
1600 - debian/rules installs /bin/login non-setuid by default, just in case...
1601 - build Debian packages with cracklib support (depends on cracklib-runtime)
1603 shadow-980724 => shadow-981228
1605 - login now clears the username in argv[] (in case someone types the
1606 password instead of username, by mistake)
1607 - i18n support, Greek translation (Nikos Mavroyanopoulos), see README.nls
1608 - updated author's e-mail address (jfh@tab.com -> jfh@bga.com)
1609 - new getpass() replacement that displays *'s (Pavel Machek)
1610 - no password required when logging in from ttys listed under
1611 NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
1612 - fixed limits code so RLIMIT_AS should work
1613 - upgraded to Debian 2.0
1614 - built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
1615 in reasonable time again
1616 - upgraded to automake-1.3, libtool-1.0h (also new config.guess and
1617 config.sub that work on i686)
1618 - usermod fixed to handle group names starting with digits (not recommended)
1620 shadow-980626 => shadow-980724
1622 - security: login no longer gives you a root shell if setgid()
1623 or initgroups() or setuid() fails for any reason, discovered
1624 by Ted Hickman <thickman@sy.net>
1625 - remove libshadow.so -> libshadow.so.x.x symlink after install
1626 - a few int -> uid_t type cleanups
1627 - fail immediately (don't retry) in *_lock() if euid != 0
1628 - added sample PAM config files etc/pam.d/{passwd,su}
1629 - preliminary PAM support in su (untested - use at your own risk,
1630 comments and patches welcome!)
1631 - cleanup and more comments in OPIE code (Algis Rudys)
1632 - added support for TCFS (Transparent Cryptographic File System)
1633 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/
1634 for more info), thanks to Aniello Del Sorbo
1636 shadow-980529 => shadow-980626
1638 - fixed bug in commonio_lock() (infinite recursion if lckpwdf() not
1639 used and database cannot be locked), thanks to Jonathan Hankins
1640 - fixed bug in copy_tree() (NUL-terminate readlink() results),
1641 thanks to Lutz Schwalowsky
1642 - no need to press Enter after Ctrl-C to interrupt password prompt
1643 - removed a few harmless gcc warnings
1644 - secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)
1645 - faillog.8: changed /usr/adm -> /var/log
1646 - pwconv.8: documented that it may fail on invalid password files
1648 shadow-980417 => shadow-980529
1650 - fixed "interesting" strzero() bug introduced by me in 980417:
1651 strzero(cp) didn't work as intended (the macro used a local
1652 variable called "cp" - oops...); Leonard N. Zubkoff was the
1653 first person to report it - thanks!
1654 - fixed usermod -e to accept empty argument (like useradd),
1655 thanks to Martin Bene
1656 - several changes from Debian 980403-0.2, see debian/changelog
1657 - added contrib/shadow-anonftp.patch (not yet merged, sorry...)
1658 thanks to Calle Karlsson
1660 shadow-980403 => shadow-980417
1662 - fixed login session limits (again - broken since 980130)
1663 - more symbolic constants for exit status values
1664 - fixed logoutd to work with 8-character usernames in utmp
1665 (no room for terminating NUL!)
1666 - various fixes to make the code more glibc2-friendly
1667 - updated doc/cracklib26.diff (fix for empty gecos, etc.)
1668 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1671 shadow-980130 => shadow-980403
1673 - security: su now creates the sulog file (if enabled and doesn't
1674 already exist) with umask 077
1675 - hopefully removed arbitrary group size limits (not yet for
1676 shadow groups though - sgetsgent() still needs a rewrite,
1677 but I don't want to delay this release any longer...)
1678 - fixed NULL dereference in groupmod -n
1680 shadow-971215 => shadow-980130
1682 - Debian binary packages can be built without root privileges
1683 (tar wrapper - debian/tar.c)
1684 - new subdir "redhat" (needs more work, see redhat/README)
1685 - in several places, exit(127) if exec fails with ENOENT, and
1686 exit(126) on other errors (as in ksh and bash)
1687 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1688 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1689 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1690 - handle crypt() returning NULL (possible according to Single Unix
1691 Spec) more gracefully (exit instead of SIGSEGV)
1692 - fixed bug in putgrent() that showed up when realloc() moved the
1693 buffer while expanding it, thanks to Floody <flood@evcom.net>
1694 - fixed bug in login session limits (with a limit set to N logins,
1695 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1696 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1697 - newer config.guess and config.sub (should work on x86 for x > 5)
1698 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1699 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1700 - documented more (not all yet) login.defs(5) settings
1701 - replaced more exit status numeric values with #defines
1702 - shadow-utils.spec now generated from shadow-utils.spec.in
1703 (so I don't have to edit version numbers for every new release)
1704 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1705 ("force" - exit(0) if the group already exists); other RedHat-
1706 specific options not added yet (best done in a perl script that
1707 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1708 - added -O option (override login.defs values) to useradd and groupadd
1709 - if usermod can't update the group file(s), exit(10) but update the
1710 password file(s) anyway (as documented by Solaris man page)
1711 - useradd should no longer set sp_expire to the current date (oops)
1712 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1713 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1714 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1715 detection, setpgrp vs. setpgid, other minor tweaks
1716 - various */Makefile.am tweaks
1717 - login.defs: added FAKE_SHELL - program to run instead of the login
1718 shell, with the real shell in argv[0] (Frank Denis)
1719 - login.defs: ignore case in yes/no settings
1720 - more E_* defines instead of hardcoded numbers for exit()
1721 - added sanitize_env() for setuid programs
1722 - login_desrpc() checks for getnetname() errors
1723 - new password is not "too similar" if it is long enough
1724 - replacement strstr() was static, no one noticed :-)
1725 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1726 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1727 - login sets $REMOTEHOST for remote logins
1728 - added newgrp -l option (Single Unix Spec, same as "-")
1729 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1730 200K of disk space on Linux/x86), enabled by default if supported by
1731 the system, use ./configure --disable-shared if it causes any problems.
1732 Warning: libshadow.so is intended for internal use by this package
1733 only - binary compatibility with future releases is not guaranteed.
1734 There should be no need to link any other programs with libshadow.so -
1735 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1736 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1737 version (!) - added check to configure; fixed do_pam_passwd prototype
1738 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1739 - added information about the new ftp site to doc/README.mirrors
1741 shadow-971001 => shadow-971215
1743 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1744 - updated the RPM .spec file
1745 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1746 (glibc defines something else named "rlogin" in utmpbits.h ?)
1747 - added MD5 checksums in Debian packages
1748 - added -p and -g options to vipw (edit the password or group file
1749 respectively, regardless of the command name in argv[0])
1750 - removed old DBM support (NDBM code is still there)
1751 - fixed a bug in gpasswd: current username was incorrectly identified as
1752 "root" because of setuid(0) done too early. It may be a security hole
1753 when using shadow groups - if "root" is listed as a group administrator,
1754 any user can add/remove members in that group. Thanks to Jesse Thilo.
1755 - gpasswd now logs which user (root or group admin) made the changes
1756 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1757 - newgrp and add_groups() allocate supplementary group lists dynamically
1758 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1759 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1760 changed by regular users (any combination of letters "frwh")
1761 - fixed contrib/pwdauth.c segfault with non-existent usernames
1762 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1763 - new date parsing code (from GNU date) used by useradd, usermod, chage
1764 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1765 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1766 - fixed useradd -G segfault (one '*' that shouldn't be there)
1767 - allow 8-bit characters in chfn
1768 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1769 - changed the handling of NIS plus entries in password files
1770 - some more tweaking in various debian/* files
1771 - logoutd uses getutent() instead of reading utmp file directly
1772 - fixed lckpwdf() called twice (and failing) when changing password
1773 if the user is not listed in /etc/shadow (Mike Pakovic)
1774 - erase and kill characters left unchanged if not defined in login.defs
1776 shadow-970616 => shadow-971001
1778 - Debian: mkpasswd no longer installed (dbm files not supported)
1779 - chpasswd checks for shadow/non-shadow at run time, too
1780 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1781 - changed libmisc/login_access.c as suggested by Dave Hagewood
1782 - replaced sprintf() with snprintf() in several places
1783 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1784 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1785 - non-root users can only run su with a terminal on stdin
1786 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1787 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1788 in libc, or system misconfiguration. Needs further investigation.
1789 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1790 - fixed free() called twice in libmisc/mail.c
1791 - added information about mirror sites (doc/README.mirrors)
1792 - updated pwconv.8 and pwunconv.8 man pages
1793 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1794 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1795 - corrected su.1 man page ($SHELL not used)
1796 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1797 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1798 - cleaned up PASS_MAX in getpass() (127 always assumed)
1799 - default editor for vipw changed from /bin/ae to a real editor :)
1801 shadow-970601 => shadow-970616
1803 - fixed execlp call (missing NULL) in src/vipw.c
1804 - vipw now preserves permissions on edited files
1805 - commented out the xdm-shadow hack in shadowconfig
1806 - improved RedHat spec file (Timo Karjalainen)
1807 - updated mailing list information
1808 - added information about the shadow paper (doc/README.shadow-paper)
1809 - renamed doc/console.c.spec (confused RPM)
1811 shadow-970502-2 => shadow-970601
1813 - fixed a typo in libmisc/mail.c causing login to segfault
1814 if MAIL_CHECK_ENAB=yes (sorry!)
1815 - patches for OPIE support (Algis Rudys) (untested)
1816 - programs that modify /etc/passwd or /etc/shadow will use
1817 lckpwdf() if available
1818 - now compiles with PAM support! (still untested)
1819 - cosmetic error message changes (prefixed by argv[0]:)
1821 shadow-970216 => shadow-970502-2
1823 - shadow group support fixes (grpconv didn't work - for some
1824 reason, putsgent() returns 1 instead of 0 on success;
1825 now -1 = failure, anything else = success)
1826 - upgraded to autoconf-2.12
1827 - pwconv and pwunconv now follow other UN*X systems and SVID3
1828 (modify files in place), original versions moved to "old"
1829 - scologin.c moved to "old" (it was only for SCO Xenix) so
1830 people stop sending patches for scologin.c gcc warnings :)
1831 - don't use the MD5* functions in libmisc/salt.c (glibc has
1832 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1833 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1834 - "passwd -S -a" now really works
1835 - support for Debian, vipw, a few fixes (Guy Maor)
1836 - src/login.c radius bug fix (Rafal Maszkowski)
1837 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1838 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1839 - limits.5 man page (Luca Berra)
1840 - expiry will work setgid shadow too, removed euid 0 check
1841 - added check for a64l() to configure (glibc)
1843 shadow-961025 => shadow-970216
1845 - major rewrite of *io.c (no more 4 copies of almost identical code)
1846 - use fsync() (if available) instead of sync() when updating password files
1847 - use fchmod() and fchown() if available
1848 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1849 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1850 - passwd -S -a: list information about all users (root only)
1851 - passwd -k: change only expired passwords
1852 - passwd -q: quiet mode
1853 - first attempt at PAM support in passwd
1854 - passwd updates the non-shadow password if /etc/shadow exists but the
1855 user has no shadow password
1856 - passwd logs who changed the password, added hook to allow non-root
1857 administrators who can change passwords (not implemented yet)
1858 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1859 - added -p (set encrypted password) option to useradd and usermod
1860 (idea from hpux10 - undocumented option used internally by SAM)
1861 - useradd -D -e does the right thing (set default expiration date)
1862 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1863 because there are just too many systems that need different commands
1864 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1865 faillog file format has been changed (somewhere between 960129 and
1866 960810), please truncate the old file (if any) to zero length
1867 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1868 - wtmp, lastlog, faillog file location guessed by configure
1869 - separate checks for invalid user and group names, max username length
1870 based on struct utmp (it's not always 8 characters)
1871 - pwck and grpck now check for invalid user/group names
1872 - pwck -q (quiet, report only serious problems) option added
1873 - separate cleaner sgetpwent() without the NIS magic
1874 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1875 - various code cleanups
1876 - new get_my_pwent() function for getting my own username, uid etc.
1877 - faillog opens the file read-write if possible (even if not root)
1878 - passwd -S allowed for normal users (for their own uid only)
1879 - handle the case of login denied to passwordless accounts better
1880 ("Login incorrect" without "Password:" prompt looks strange)
1881 - corrected author information and removed a copyright restriction
1883 shadow-960925 => shadow-961025
1885 - fixed a few typos in shadow group code
1886 - don't check for names starting with 'r' to determine if the shell
1887 is restricted, use /etc/shells instead (for the "rc" shell)
1888 - removed extra definition of LASTLOG_FILE in configure.in
1889 - expiry no longer segfaults if no /etc/shadow
1890 - userdel -r "can't remove mailbox" warning no longer printed on success
1891 - useradd exit codes changed to match hpux10 man page
1892 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1894 shadow-960920 => shadow-960925
1896 - bug fixes to the new environment code using malloc
1897 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1898 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1899 - small fix to isexpired(), and use it in passwd as well
1900 - use strftime() and strptime() if available
1901 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1902 contain encrypted passwords!)
1903 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1904 (nothing bad happened yet, just a cleanup)
1905 - gpasswd should work with both shadow and non-shadow group passwords
1906 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1907 - passwd -e for sunos4 (ATT_AGE), untested
1908 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1909 - small fix to l64a()
1910 - passwd prints a message after password successfully changed (for things
1911 like poppassd which run passwd and expect some output)
1912 - passwd logs if password was changed by root (as opposed to a luser)
1913 - passwd uses current uid if no username argument and getlogin() fails
1915 shadow-960910 => shadow-960920
1917 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1918 - newusers should work with both shadow and non-shadow passwords
1919 (still left to do: chpasswd, gpasswd)
1920 - login-static no longer compiled by default
1921 - more SYSLOG() macros
1923 shadow-960810 => shadow-960910
1925 - updated README.linux to point to the new ftp site
1926 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1927 - man pages now closer to LDP standards (Ivan Nejgebauer)
1928 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1929 - obscure.c fixed to compile with HAVE_LIBCRACK
1930 - cosmetic message changes in age.c
1931 - utmp open error check fixed in utmp.c
1932 - grpunconv added (Michael Meskes)
1933 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1934 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1935 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1936 - passwords can be changed if sp_max == -1 (now considered infinity)
1937 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1938 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1939 - contrib/rpasswd.c added (Joshua Cowan)
1940 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1941 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1942 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1944 shadow-960129 => shadow-960810
1946 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1947 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1948 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1949 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1950 - hopefully removed all the rcsid warnings
1951 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1952 - resource limits (Cristian Gafton)
1953 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1954 - more fixes in man pages
1955 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1956 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1957 su, useradd, userdel, usermod) should now work with both shadow and
1958 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1959 run time); a few programs still left to do
1960 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1961 - new contrib/adduser.c from Chris Evans
1962 - lots of other minor changes
1963 - source tree reorganization, GNU autoconf, portability cleanups
1964 - basename() renamed to Basename() to avoid name space confusion
1965 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1966 - newgrp cleanup and a few fixes
1967 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1968 - don't make the first group member the group admin by default
1969 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1970 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1971 place (defines.h) instead of repeating it in all source files...
1972 - added userdel -r safety check (refuse to remove the home directory
1973 if it would result in removing some other user's home directory)
1974 - usermod -u now correctly checks for non-unique uid (unless -o)
1975 - sync() after updating password files, just to be more safe
1976 - "make install" should install /etc/login.defs if it doesn't exist
1977 - new option to control what happens if we can't cd to the home directory
1978 (DEFAULT_HOME in /etc/login.defs)
1979 - enter the home directory as the user, not as root (for NFS etc.)
1980 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1981 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1982 possible to add specified groups (floppy etc.) for console logins
1983 - new faillog feature: lock account for specified (per-user) time since
1984 the last failure after exceeding the failure limit
1985 - new man pages (gpasswd.1, login.access.5, suauth.5)
1986 - fixes in man pages, renamed *.4 to *.5
1987 - new "contrib" directory (two adduser programs)
1988 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1989 - sulogin no longer requires to be run from init, should work from rc
1991 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1992 using xx_locate(), modify it and call xx_update(), don't write back
1993 anything returned by getpwnam() etc.)
1994 - stupid bug fixed in lastlog.c
1995 - don't move non-directories in "usermod -m"
1996 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1997 - macros to get around ancient compilers which don't like prototypes
1998 - make more use of "const" (not everywhere yet)
1999 - added #ifdef AUTH_METHODS - very few people use administrator defined
2000 authentication methods because many programs are not aware of them;
2001 not supporting them makes the code simpler
2002 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
2003 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
2004 see HAVE_SGETGRENT in config.h (grent.c)
2005 - don't use continued lines in /etc/group, the standard getgr*() functions
2006 don't support that (grent.c)
2007 - removed the third main() argument (according to libc docs, not allowed by
2008 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
2009 - login access control (lmain.c, login_access.c)
2010 - added copyright notice to login_access.c (from logdaemon-5.0)
2011 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
2012 - added closelog() in su before executing the shell (smain.c)
2013 - getting current user name changed (smain.c)
2014 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
2015 - getpass() shouldn't return NULL except on errors (getpass.c)
2016 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
2017 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
2018 - can use shadow support in new versions of Linux libc instead of libshadow.a,
2019 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
2020 - "no shadow password" not logged, the same /bin/login should work with both
2021 shadow and non-shadow passwords (lmain.c)
2022 - some cleanup in various places (lmain.c, passwd.c)
2023 - new program to verify username/password pairs, for xlock etc.; it is not
2024 installed by default, read the comments first (pwdauth.c)
2025 - authentication programs run with empty environment for safety (pwauth.c)
2026 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
2027 - common code separated from *io.c (commonio.c)
2028 - ownership and permissions on password files are now preserved (we may try
2029 to make more use of setgid and setuid non-root programs in the future)
2030 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
2031 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
2032 - termios/termio/sgtty macros cleaned up a bit
2034 shadow-951218 => shadow-960129
2036 Emergency bug fix release - no new features since 951218. There are many
2037 new changes, but this bug really can't wait until they are tested.
2039 Probably all previous versions of the shadow suite have a serious bug which
2040 makes it possible to overwrite the stack by entering very long username at
2041 the login prompt. This can give root access to any remote user!
2043 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
2044 size of the array in lmain.c). Aaargh!!!
2046 shadow-951203 => shadow-951218
2049 - Linux utmp handling fixes (utmp.c)
2050 - last failure date printing fixes (failure.c)
2051 - minor fix to compile with USE_CRACKLIB (obscure.c)
2052 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
2053 - basename.c added, replacing duplicated code in various places
2054 - "su -" runs the shell with '-' in argv[0] again (smain.c)
2055 - removing at/cron jobs cleaned up (userdel.c)
2056 - /etc/gshadow should not be world-readable (sgroupio.c)
2057 - if fflush() failed, files were not closed (*io.c)
2058 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
2059 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
2060 - some minor cleanups for gcc -Wall (unused variables etc.)
2061 - removed README.FIRST (copyrights are OK now)
2062 - updated ANNOUNCE, README.linux, WISHLIST
2063 - as suggested, converted to RCS
2065 shadow-3.3.2-951127 => shadow-951203-jfh
2068 - Added the BSD-style copyright to all of the files. Any files with the
2069 old copyright have multiple copyright holders and need to be cleanroomed
2070 to produce BSD-style copyrightable files, or I need to get the consent
2071 of the others to change the copyright.
2072 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
2073 that all of the files should have the correct copyright there is no need
2074 to refer to that e-mail message.
2075 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
2076 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
2078 jfh@rpp386.cactus.org
2080 shadow-3.3.2-951106 => shadow-951127
2082 Note: for now this code only supports Linux. All the #ifdef's are there
2083 (and will be; support for at least SunOS 4.1.x would be nice) but:
2084 - I had to fix some potential security problems resulting from sloppy
2085 coding (no bounds checking), and it was easier for me to use snprintf()
2086 (not available on many systems, unfortunately), I'll fix that later.
2087 Old versions of Linux libc don't have snprintf() either, and the one
2088 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
2089 - I am lazy and only updated Makefile.linux and config.h.linux this time
2090 - I don't have root access to non-Linux systems (this means no testing)
2091 - this code needs some major reorganization, which will (hopefully)
2095 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
2096 - login can be statically linked (not that I think it's a good idea, better
2097 fix the telnetd, but paranoid people will like it :-)
2098 - login is installed non-setuid by default
2099 - check for NULL from getpass()
2100 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
2101 - use standard "Password: " prompt by default (pwauth.c)
2102 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
2103 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
2104 - Linux has <lastlog.h>
2105 - print ll_host on Linux too (lmain.c)
2106 - size checking in various places (setuid root programs, argh!)
2107 - preserve TERM from getty (lmain.c)
2108 - don't ignore SIGHUP (lmain.c)
2109 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
2110 - remove LD_xxx (env.c)
2111 - use bzero() instead of memset() for BSD portability and less #ifdef's
2112 (if the system has no bzero(), implement it as a macro using memset())
2113 - the above fixes wrong order of memset() parameters (log.c)
2114 - use getutent/pututline instead of doing it by hand (utmp.c)
2115 - added the new settings to login.defs.linux
2116 - added login_access.c to the distribution (not used yet)
2120 shadow-3.3.2 => shadow-3.3.2-951106
2122 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
2123 - malloc/strdup error checking, hopefully no more core dumps...
2124 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
2125 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
2126 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
2127 - use POSIX termios whenever possible on Linux
2128 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
2129 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
2130 - login -h only for root (lmain.c)
2131 - login -r not needed for Linux (lmain.c)
2132 - sample login.defs modified for Linux (login.defs.linux)
2133 - swapped chfn USAGE and ADMUSAGE (chfn.c)
2134 - added -u to passwd usage (passwd.c)
2135 - no #! check necessary for Linux (shell.c)
2136 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
2137 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
2138 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
2139 can now be set in login.defs, old values are used as defaults (lmain.c)
2140 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
2141 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
2142 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
2143 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
2144 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
2145 - check for weak passwords too if previous password was empty (obscure.c)
2146 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
2147 - Linux has getusershell(), use it (chsh.c)
2148 - check if the new shell is executable by the user (chsh.c)
2149 - sleep before printing "Login incorrect", not the other way around (lmain.c)
2150 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
2151 - do "wheel group" more like BSD does (smain.c)
2152 - use getlogin() in su (smain.c)
2153 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
2154 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
2155 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
2156 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
2157 - LOGIN_STRING should work now (pwauth.c, getdef.c)
2158 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
2159 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
2160 not lost when you copy the right ones to Makefile and config.h
