3 shadow-4.1.4.3 -> shadow-4.1.5 UNRELEASED
6 * su -c could be abused by the executed command to invoke commands with
7 the caller privileges. See below.
10 * report usage error to stderr, but report usage help to stdout (and return
11 zero) when explicitly requested (e.g. with --help).
12 * initial support for tcb (http://openwall.com/tcb/) for useradd,
13 userdel, usermod, chage, pwck, vipw.
14 * Added support for ACLs and Extended Attributes in useradd and usermod.
15 Support shall be enabled with the new --with-acl or --with-attr
17 * Added diagnosis for lock failures.
24 * When the gshadow file exists but there are no gshadow entries, an entry
25 is created if the password is changed and group requires a
29 * PAM enabled versions: restore the -e option to allow restoring
30 passwords without knowing those passwords. Restore together the -m
31 and -c options. (These options were removed in shadow-4.1.4 on PAM
33 * When the shadow file exists but there are no shadow entries, an entry
34 is created if the password is changed and passwd requires a
40 * The -l, -m, -r, -t options only act on the existing users, unless -a is
50 * Fix parsing of gshadow entries.
53 * Fixed groupmod when configured with --enable-account-tools-setuid.
54 * When the gshadow file exists but there are no gshadow entries, an entry
55 is created if the password is changed and group requires a
59 * NIS entries were dropped by -s (sort).
67 * Fixed limits support (non PAM enabled versions only)
68 * Added support for infinite limits and group based limits (non PAM
69 enabled versions only)
70 * Fixed infinite loop when CONSOLE is configured with a colon-separated
72 * Fixed warning and support for CONSOLE_GROUPS for users member of more
74 * Do not log into utmp(x) or wtmp when PAM is enabled. This is done by
77 * Fix parsing of gshadow entries.
81 * NIS entries were dropped by -s (sort).
87 * If the skeleton directory contained hardlinked files, copies of the
88 hardlink were removed from the skeleton directory.
91 * Check the existence of the user's mail spool before trying to remove
92 it. If it does not exist, a warning is issued, but no failure.
93 * Do not remove a group with the same name as the user (usergroup) if
94 this group isn't the user's primary group.
97 * Accept options in any order (username not necessarily at the end)
98 * When the shadow file exists but there are no shadow entries, an entry
99 is created if the password is changed and passwd requires a
100 shadow entry, or if aging features are used (-e or -f).
103 * Document the su exit values.
104 * When su receives a signal, wait for the child to terminate (after
105 sending a SIGTERM), and kill it only if it did not terminate by itself.
106 No delay will be enforced if the child cooperates.
107 * Default ENV_SUPATH is /sbin:/bin:/usr/sbin:/usr/bin
108 * Fixed infinite loop when CONSOLE is configured with a colon-separated
110 * Fixed warning and support for CONSOLE_GROUPS for users member of more

137 shadow-4.1.4.2 -> shadow-4.1.4.3 2011-02-15
140 - CVE-2011-0721: An insufficient input sanitation in chfn can be exploited
141 to create users or groups in a NIS environment.
143 shadow-4.1.4.1 -> shadow-4.1.4.2 2009-07-24
146 * Improved support for large groups (impacts most user/group management
149 - addition of system users or groups
150 * Speed improvement. This should be noticeable in case of LDAP configured
151 systems. This should impact useradd, groupadd, and newusers
152 * Since system accounts are allocated from SYS_?ID_MIN to SYS_?ID_MAX in
153 reverse order, accounts are packed close to SYS_?ID_MAX if SYS_?ID_MIN
154 is already used but there are still dome gaps.
157 * Add support for shells being a shell script without a shebang.
159 * Preserve the DISPLAY and XAUTHORITY environment variables. This was
160 only the case in the non PAM enabled versions.
161 * Add support for shells being a shell script without a shebang.
164 * The Finnish translation of passwd(1) was outdated and is no more
167 shadow-4.1.4 -> shadow-4.1.4.1 2009-05-22
170 * Fix failures with empty usernames on non PAM versions.
171 * Fix CONSOLE (securetty) support on non PAM versions.
173 * Return the exit status of the child.
175 * On Linux, do not check if an user is logged in with utmp, but check if
176 the user is running some processes.
177 * If not on Linux, continue to search for an utmp record, but make sure
178 the process recorded in the utmp entry is still running.
179 * Report failures to remove the user's mailbox
180 * When USERGROUPS_ENAB is enabled, remove the user's group when the
181 user was the only member.
182 * Do not fail when -r is used and the home directory does not exist.
184 * Check if the user is busy when the user's UID, name or home directory
187 shadow-4.1.3.1 -> shadow-4.1.4 2009-05-10
190 * Enable --enable-account-tools-setuid by default for PAM builds.
191 * Add configure option --enable-utmpx, disabled by default to mimic
192 the previous behavior on Linux (where utmp and utmpx are identical).
193 * Fix build failure on non-PAM systems when --without-pam is not
197 * Change the passwords using PAM. This permits to define the password
198 policy in a central place. The -c/--crypt-method, -e/--encrypted,
199 -m/--md5 and -s/--sha-rounds options are no more supported on PAM
202 * Warn if a group has an entry in group and gshadow, and the password
203 field in group is not 'x'.
205 * Do not trust the current utmp entry's ut_line to set PAM_TTY. This could
207 * (PAM) Even if the user was already authenticated (-f flag), ask the
208 user to update his authentication token if needed.
210 * Fix regression causing empty reports.
212 * Change the passwords using PAM. This permits to define the password
213 policy in a central place. The -c/--crypt-method and -s/--sha-rounds
214 options are no more supported on PAM enabled systems.
216 * Warn if an user has an entry in passwd and shadow, and the password
217 field in passwd is not 'x'.
220 - Updated Czech translation
221 - Updated French translation
222 - Updated German translation
223 - Updated Japanese translation
224 - Updated Korean translation
225 - Updated Portuguese translation
226 - Updated Russian translation
228 shadow-4.1.3 -> shadow-4.1.3.1 2009-04-15
231 - Due to bad parsing of octal permissions, the permissions on tty (login)
232 but also UMASK were set wrongly (and weirdly). Only shadow-4.1.3 was
237 * Fix regression when no user is specified on the command line.
239 * Fixed SE Linux support
241 * SE Linux: Set the default context to the context of the file being
242 edited. This ensures that the backup file inherit from the file's
246 - Updated Norwegian Bokmål translation
248 shadow-4.1.2.2 -> shadow-4.1.3 2009-04-12
252 * Fixed support for OpenPAM.
253 * Fixed support for uclibc.
254 * Added configure --enable-account-tools-setuid (default) /
255 --disable-account-tools-setuid options. This permits to disable the
256 PAM authentication of the caller for chage, chgpasswd, chpasswd,
257 groupadd, groupdel, groupmod, newusers, useradd, userdel, and usermod.
258 This authentication is not necessary when these tools are not
259 installed setuid root.
260 * Added configure --with-group-name-max-length (default) /
261 --without-group-name-max-length options. This permits to configure the maximum length allowed for group names:
262 <no option> -> default of 16 (like today)
263 --with-group-name-max-length -> default of 16
264 --without-group-name-max-length -> no max length
265 --with-group-name-max-length=n > max is set to n
266 No sanity checking is performed on n so people could do
267 something neat like --with-group-name-max-length=MAX_INT
268 - addition of users or groups
269 * Speed improvement in case UID_MAX/SYS_UID_MAX/GID_MAX/SYS_GID_MAX is
270 used for an user/group. This should be noticeable in case of LDAP
271 configured systems. This should impact useradd, groupadd, and newusers
272 - error handling improvement
273 * Make sure errors and incomplete changes are reported to syslog and
274 audit in case of unexpected failures.
275 * Report system inconsistencies to syslog and audit.
276 * Only report success to syslog and audit if the changes are really
277 performed in the system databases.
278 This is still not complete.
280 * New CREATE_HOME variable to tell useradd to create a home directory by
283 * New Kazakh translation.
284 * Spanish manpages are no more distributed. They are outdated. Please
285 contact pkg-shadow-devel@lists.alioth.debian.org if you wish to
289 * Accept users specified as a numerical UID, or ranges of users (-user,
291 * -l, -m, and -r now apply not only to existing users, but to all the
293 * Options can be specified in any order.
295 * Added support for long options --add (-a), --delete (-d),
296 --remove-password (-r), --restrict (-R), --administrators (-A), and
298 * Added support for usernames with arbitrary length.
299 * audit logging improvements.
300 * error handling improvement (see above).
301 * Log permission denied to syslog and audit.
303 * audit logging improvements.
304 * error handling improvement (see above).
305 * Speedup (see "addition of users or groups" above).
306 * do not create groups with GID set to (gid_t)-1.
307 * Allocate system group GIDs in reverse order. This could be useful
308 later to increase the static IDs range.
310 * audit logging improvements.
311 * error handling improvement (see above).
313 * Check if user exist before they are added to groups.
314 * Avoid segfault in case the specified group does not exist in /etc/group.
315 * Everybody is allowed to list the users of a group.
316 * /etc/group is open readonly when one just wants to list the users of a
318 * Added syslog support.
319 * Use the groupmems PAM service name instead of groupmod.
320 * Fix segmentation faults when adding or removing users from a group.
321 * Added support for shadow groups.
322 * Added support long options --add (-a), --delete (-d), --purge (-p),
323 --list (-l), --group (-g).
325 * audit logging improvements.
326 * error handling improvement (see above).
327 * do not create groups with GID set to (gid_t)-1.
329 * warn for groups with GID set to (gid_t)-1.
331 * Restore the echoctl, echoke, onclr flags to the terminal termio flags.
332 Reset echoprt, noflsh, tostop. This behavior seems to have change by
333 mistake in earlier releases (4.0.8, for no obvious reason).
335 * Implement the -r, --system option.
336 * Speedup (see "addition of users or groups" above).
337 * do not create users with UID set to (gid_t)-1.
338 * do not create groups with GID set to (gid_t)-1.
339 * Allocate system account UIDs/GIDs in reverse order. This could be useful
340 later to increase the static IDs range.
342 * For compatibility with other passwd version, the --lock an --unlock
343 options do not lock or unlock the user account anymore. They only
344 lock or unlock the user's password.
346 * warn for users with UID set to (uid_t)-1.
348 * Preserve COLORTERM in addition to TERM when su is called with the -l
351 * audit logging improvements.
352 * Speedup (see "addition of users or groups" above).
353 * See CREATE_HOME above.
354 * New -M/--no-create-home option to disable CREATE_HOME.
355 * do not create users with UID set to (gid_t)-1.
356 * Added -Z option to map SELinux user for user's login.
357 * Allocate system user UIDs in reverse order. This could be useful
358 later to increase the static IDs range.
360 * audit logging improvements.
361 * Do not fail if the removed user is not in the shadow database.
362 * When the user's group shall be removed, do not fail if this group is
363 not in the gshadow file.
364 * Delete the SELinux user mapping for user's login.
366 * Allow adding LDAP users (or any user not present in the local passwd
367 file) to local groups
368 * do not create users with UID set to (gid_t)-1.
369 * Added -Z option to map SELinux user for user's login.
371 shadow-4.1.2.1 -> shadow-4.1.2.2 23-11-2008
374 - Fix a race condition in login that could lead to gaining ownership or
375 changing mode of arbitrary files.
376 - Fix a possible login DOS, which could be caused by injecting forged
379 shadow-4.1.2 -> shadow-4.1.2.1 26-06-2008
382 - Fix an "audit log injection" vulnerability in login.
383 This vulnerability makes it easier for attackers to hide activities by
384 modifying portions of log events, e.g. by appending an addr= statement
387 shadow-4.1.1 -> shadow-4.1.2 25-05-2008
390 - generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
391 chgpasswd; and also passwd if configured without PAM support).
392 The number of rounds and number of salt bytes was fixed to their lower
393 allowed values (resp. configurable and 8), hence voiding some of the
394 advantages of this encryption method. Dictionary attacks with
395 precomputed tables were easier than expected, but still harder than with
396 the MD5 (or DES) methods.
400 * Distribute the chfn, chsh, and userdel PAM configuration file.
401 * Fix the detection of the audit, pam, and selinux library and header
402 file; and fail if the feature is requested but not present on the
404 * Fix build failure when configured with audit support.
406 * Allow non-US-ASCII characters in the GECOS fields ("name", "room
407 number", and "other info" fields).
409 * Do not fail if a shell option, specified after --, has more than 2
412 * If the SULOG_FILE does not exist when an su session is logged, make
413 sure the file is created with group root, instead of using the group
416 * Resume properly after ^Z.
419 - Document the -r, --system option in the useradd, groupadd, and newusers
421 - Document the -c, --crypt-method and -s, --sha-rounds options in the
423 - Document the -k, --skel option in the useradd manpage.
424 - Tag the section which require --enable-shadowgrp or --with-sha-crypt
427 shadow-4.1.0 -> shadow-4.1.1 02-04-2008
431 * Do not seed the random number generator each time, and use the time in
432 microseconds to avoid having the same salt for different passwords
433 generated in the same second.
435 * Do not install the shadow library per default.
437 * Do not translate the messages sent to syslog. This avoids logging
438 PAM error messages in the users's locale.
440 * Set GID_MIN to the same value as UID_MIN by default (1000).
441 * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
442 SYS_GID_MAX (999) for system accounts.
444 * /etc/default/useradd now defines HOME as /home to match FHS.
446 * Fix bug which forbid to set the aging information of an account with a
447 passwd entry, but no shadow entry.
449 * faillog -r now only reset the entries of existing users. This makes
452 * Fix failures when the gshadow file is not present.
453 * When a password is moved to the gshadow file, use "x" instead of "x"
454 to indicate that the password is shadowed (consistency with grpconv).
455 * Make sure the group and gshadow files are unlocked on exit.
457 * New option -p/--password to specify an encrypted password.
458 * New option -r, --system for system accounts.
460 * Do not fail if the group does not exist in the gshadow file.
461 * Do not rewrite the group or gshadow file in case of error.
462 * Make sure the group and gshadow files are unlocked on exit.
463 * Fail if the system is not configured to support split groups and
464 different group entries have the name of the group to be deleted.
466 * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
468 * New option -p/--password to specify an encrypted password.
469 * Make sure the group and gshadow files are unlocked on exit.
470 * When the GID of a group is changed, update also the GID of the passwd
471 entries of the users whose primary group is the group being modified.
473 * Fix logging of changes to syslog when a group file is provided,
474 without a gshadow file.
476 * Accept users specified as a numerical UID, or ranges of users (-user,
479 * Use PATH and SUPATH to set the PATH environment variable, even when
480 support for PAM is enabled.
481 * If started as init, start a new session.
483 * Fix segfault when an user returns to an unknown GID (either the user
484 was deleted during the user's newgrp session or the user's passwd
485 entry referenced an invalid group). Add a syslog warning in that case.
486 * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
487 changing the user space group ID with newgrp or sg.
489 * The new users are no more added to the list of members of their groups
490 because the membership is already set by their primary group.
491 * Added support for gshadow.
492 * Avoid using the same salt for different passwords.
493 * Fix support for the NONE crypt method.
494 * newusers will behave more like useradd regarding the choice of UID or
495 GID or regarding the validity of user and group names.
496 * New option -r, --system for system accounts.
497 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
500 * Make sure that no more than one username argument was provided.
501 * Make SE Linux tests more strict, when the real UID is 0 SE Linux
502 checks will be performed.
504 * Fix logging of changes to syslog when a passwd file is provided,
505 without a shadow file.
507 * su's arguments are now reordered. If needed, use -- to separate su's
508 options from the shell's options.
510 * If started as init, start a new session.
512 * New option -l to avoid adding the user to the lastlog and faillog databases.
513 * Fix the handling of the --defaults option (it required an argument,
514 but should behave as -D)
515 * Document the --defaults option, which was already described in the
516 useradd's Usage information.
517 * New option -r, --system for system accounts.
518 * New options -U, --user-group and -N, --no-user-group. These options
519 should replace nflg from the previous versions. Please set any -n
520 option to deprecated because its meaning differs from one distribution
522 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
525 * Keep the access and modification time of files when moving an user's home
527 * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
528 differ from the old ones. If a requested new value is equal to the old
529 one, no changes will be performed for that field. If no fields are
530 changed, usermod will exist successfully with a warning. This avoids
531 logging changes to syslog when there are actually no changes.
532 * Fix the handling of -a when a user is being renamed (with -l)
534 * Recommend editing the shadowed (resp. regular) file if the regular (resp.
535 shadowed) file was edited.
537 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2007
541 When compiled with PAM support, it used the chpasswd policy file instead
542 of the chgpasswd policy file. If an administrator added some restriction
543 to the chgpasswd policy file, they were not taken into account.
546 - Add support for SHA256 and SHA512 encrypt methods (supported by new
548 - useradd: Allow non numerical group identifier to be specified with
550 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
551 - newgrp: Do not give an indication that the group has no password. Ask
552 for the password, as if there were a password.
553 - The permissions of the suid binaries is now configurable in
554 src/Makefile.am. Note that changing the permissions is not recommended.
555 - newgrp.c: Declare the child and pid variable at the beginning of a block.
556 This fixes a compilation issue with gcc 2.95.
557 - login_nopam: Add support for systems with no innetgr(). On those
558 systems, username with an @ will be treated like any other username
559 (i.e. lookup in the local database for an user with an @). Thanks to
560 Mike Frysinger for the patch.
561 - Add support for uClibc with no l64a().
562 - userdel, usermod: Fix infinite loop caused by erroneous group file
563 containing two entries with the same name. (The fix strategy differs
565 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
566 - userdel: Abort if an error is detected while updating the passwd or group
567 databases. The passwd or group files will not be written.
568 - usermod: Update the group database before flushing the nscd caches.
569 - usermod: Make sure the group modifications will be allowed before
570 writing the passwd files.
571 - Flush the nscd tables using nscd -i instead of the private glibc socket.
572 - usermod: Make usermod options independent of the argument order.
573 - newgrp: Do not request a password when a user uses newgrp to switch to
575 - passwd: -l/-u options: edit the shadow account expiry field *in
576 addition* to editing the password field.
577 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
579 - su: Avoid terminating the PAM library in the forked child. This is done
580 later in the parent after closing the PAM session.
581 - userdel: Fix the homedir prefix checking.
582 - passwd, usermod: Refuse to unlock an account when it would result in a
583 passwordless account.
584 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
585 getgrgid(), and getspnam(). There should be no functional changes.
586 - gpasswd: Only read information from the local file group database. It
587 writes the changes in /etc/group and/or /etc/gshadow, but used to read
588 information from getgrnam (hence possibly from another group database).
589 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
590 better support for split groups. Be careful when using this variable:
591 not all tools support well split groups (in or out of the shadow
592 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
593 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
594 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
596 - chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
597 -s/--sha-rounds to supersede the system default encryption algorithm.
598 - chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
599 will respect the system default configured in /etc/login.defs
602 - Generate the translated manpages from PO at build time.
603 - The generated manpages will change depending on the configure options.
604 If you use different options than the one used for the distributed
605 archive, you should re-generate the manpages.
606 - login.defs should now describe all the variables.
607 - The tools' documentation details the login.defs variables they use.
609 shadow-4.0.18.1 -> shadow-4.0.18.2 28-10-2007
612 - usermod: fixed handle -a option (by Benno Schulenberg
613 <bensberg@justemail.net>),
614 - useradd: improved auditing support
615 (https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=211659),
616 - groupadd, groupdel, groupmod, useradd, userdel, usermod: flush nscd cashes
617 after close /etc/{group,passwd} files,
618 - su: If compiled without PAM support, enforce the limits from /etc/limits
619 when one of the -, -l, or --login options is set, even if called by root.
620 - limits: Support for 2 new resource limits: max nice value, and max real
621 time priority. The resource limits are not used when compiled with PAM.
623 - updated translations: fi, ja, nl, tl, zh_CN.
624 - groupadd.8, groupmod.8, login.1, useradd.8, userdel.8, usermod.8: grammar
625 mistakes and other corrections (by Schulenberg <bensberg@justemail.net>),
627 shadow-4.0.18 -> shadow-4.0.18.1 03-08-2006
630 - groupmems: fixed compilation when PAM is disabled
631 (by Johannes Winkelmann <jw@smts.ch>),
632 - fixed missing man pages in dist tar ball necessary on build when

1017 - merge nscd-socket-path patch from Fedora: newer glibc's have a different nscd socket
1018 location (/var/run/nscd/socket instead /var/run/.nscd_socket),
1019 - S/Key support is back,
1020 - usermod: added -a option. This flag can only be used in conjunction with the -G

1030 -- move all autoheader templates from acconfig.h to configure.in,
1031 - login: setup limits and umask (using login.defs ULIMITS and UMASK variables) only when
1032 PAM support is disabled (it is task for pam_limits and pam_umask modules),
1033 - sulogin, login: use SYSLOG macro instead syslog() which saves the locale, sets the
1034 locale to C, sends the message and restores the locale
1035 (fix by Nicolas François <nicolas.francois@centraliens.net>).

1056 - usermod: when relocating a user's home directory, don't fail and remove the new
1057 home directory if we can't remove the old home directory for some
1058 reason; the results can be spectularly poort if, for instance, only
1059 the rmdir() fails. Patch prepared by Timo Lindfors <lindi-spamtrap@newmail.com>.
1060 http://bugs.debian.org/166369
1061 - su: fix syslogs to be less ambiguous. Use old:new format instead of old-new

1063 http://bugs.debian.org/213592
1064 - removed not used now libmisc/setup.c,
1065 - login: use also UTMPX API instead UTMP on failure (login was affected for this

1127 Patch and comment by Koblinger Egmont <egmont@uhulinux.hu>:
1128 Only two arguments are passed to the open() call though it expects three
1129 because O_CREAT is present. Hence the permission of the file first becomes
1130 some random garbage found on the stack, and an attacker can perhaps open
1131 this file and hold it open for reading or writing before the proper
1132 fchmod() is executed. (Actually, we could also pass the final "mode" to
1133 the open() call and then save the consequent fchmod().)
1134 - SELinux changes: added changes in chage, chfn, chsh, passwd for allow
1135 construct more grained user password/accuunt properties on SELinux

1361 - fix bug discovered and fixed by Marcel Ritter
1362 <Marcel.Ritter@rrze.uni-erlangen.de>
1363 Due to a big buffer size in lib/commonio.c this error does only appear
1364 if a line gets longer than 4096 bytes (there are probably very few people
1365 stumbling across this).
1366 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
1371 while [ $NUM -le 1000 ]; do
1372 useradd -g demogroup -G demogroup -p "NONE" user$NUM
1375 - remove limit 32 to groups per user by (the same user can belong to
1376 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant

1389 - aplayed Debian patch to man pages for shadowconfig,
1390 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
1393 shadow-20001012 -> shadow-20001016:
1394 - conditionaly disabled body reload_nscd() because not every
1395 version of nscd can handle it (this can be enabled by define
1396 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
1397 - fixes on autoconf/automake level for dist target,

1404 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
1405 overwrite previously existing groups in adduser,
1406 - added PAM support for chage (bind to "chage" PAM config file) also
1407 added PAM support for all other small tools like chpasswd, groupadd,
1408 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
1409 "shadow" PAM config file) - this modificaytions mainly based on
1410 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
1411 - many small fixes and improvments in automake (mow "make dist"
1413 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
1415 shadow-20000826 => shadow-20000902
1417 This is probably the last release from me.
1418 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
1421 (I'm still interested to know what is going on with this package,
1422 which is fairly important to many Linux distributions, so please
1423 Cc: marekm@linux.org.pl in any related discussions - just don't
1424 expect me to respond quickly...)
1426 Previous warning still applies - be careful!
1428 - applied some of the Red Hat patches (revised slightly), thanks to
1429 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
1430 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
1431 in glibc 2.1.x) after changing anything, add usermod -L and -U
1432 options, remove LOG_CONS from openlog(), chage -d and -E handles
1433 dates in yyyy-mm-dd format ('/' is not required)
1436 shadow-19990827 => shadow-20000826
1438 WARNING: this release is not tested (other than that it compiles for me),
1439 please be careful. Previous release was a year ago, so it is really time
1440 to release something and start looking for a new, better maintainer...
1441 (I've been extremely busy recently. Credit for most of the real work,
1442 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1443 who maintains this package for Debian.)
1445 - merged most of the changes from Debian (not all of them yet, PAM support
1446 should be complete but is not tested - need to upgrade to potato first)
1447 - added Polish translations of manual pages from PLD
1448 - change sulog() to not depend on global variables oldname, name
1449 - try to not follow symbolic links when deleting files recursively
1450 in userdel (still not perfect, safest to do it in single user mode)
1451 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
1452 (a few ANSI C constructs were used already, and no one complained)
1453 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
1455 shadow-19990709 => shadow-19990827
1457 - upgrade to autoconf-2.13, automake-1.4, libtool-1.3.3
1458 - i18n: added French translation by Vincent Renardias <vincent@ldsol.com>
1459 - i18n: added Swedish translation by Kristoffer Brånemyr <ztion@swipnet.se>
1460 - logoutd no longer reads /etc/logoutd.mesg at startup - instead, read
1461 it when sending to luser's tty (no need to reload with SIGHUP)
1462 - added support for "usergroups" feature often found in Linux distributions
1463 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1464 username == groupname, then set umask to 002 instead of 022)
1465 - Debian: pwck and grpck are now run from a daily cron job (root will
1466 receive an e-mail if something is wrong), and at system startup
1467 - added support for setting umask in /etc/limits
1468 - when using OPIE, re-prompt with echo on after empty password was entered
1469 - GETPASS_ASTERISKS now run time configurable (login.defs)
1470 - getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
1471 - getpass() allows all input to be erased using Control-U, and beeps when
1472 too many characters are entered
1473 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1474 - Debian: tar wrapper no longer needed to build packages as non-root user
1475 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1476 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1477 dpkg-architecture, cross compilation, only build passwd, add
1478 etc/login.defs.hurd conffile, conditionalize CBAUD
1479 - newgrp sets $HOME before running the new shell
1480 - both "sg group command" (usage message) and "sg group -c command"
1481 (man page) work, updated both the usage message and the man page :)
1482 - i18n: added missing _() for some translatable strings
1484 shadow-19990607 => shadow-19990709
1486 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
1487 - fixed a bug in newgrp if the user is in >= 17 groups
1488 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1489 almost all programs need it if skey/opie support is enabled)
1490 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1491 - changed faillog to do something (assume -p) with no options specified
1492 - updated version of the udbachk passwd/shadow/group file integrity
1493 checker (contrib/udbachk.v012.tgz)
1495 shadow-19990307 => shadow-19990607
1497 - upgraded to libtool-1.2, latest config.{guess,sub}
1498 - added missing #include "defines.h" in libmisc/login_desrpc.c - thanks
1499 to almost everyone for reporting it :-)
1500 - moved PAM-related defines to pam_defs.h
1501 - added some braces to if/else to avoid egcs warnings
1502 - started adding PAM support to login (based on util-linux, not finished yet)
1503 - changed "!" to "x" for pw_passwd in src/newusers.c
1504 - a few more Y2K fixes
1505 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
1506 thanks to Sami Kerola
1507 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1508 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1509 - updated mailing list information (moved again, now hosted by SuSE),
1510 updated README.mirrors, other minor documentation updates
1511 - made getpass work with redirected stdin
1512 - new readpass echoing asterisks disabled by default by popular demand
1513 (can be enabled at compile time: ./configure --enable-readpass)
1514 - the random number of asterisks in readpass is now more random
1515 (random number generator initialization was missing)
1516 - commented out --enable-md5crypt (obsolete) in configure.in
1517 - when checking for libskey, link with -lcrypt if libcrypt is available
1518 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1519 - added Package/Version ident strings (so you can use the RCS "ident"
1520 command to check any binary, which version of shadow it comes from)
1522 shadow-981228 => shadow-19990307
1524 - added support for setting process priority in /etc/limits
1525 - i18n: updated Greek translation
1526 - i18n: added Polish translation by Arkadiusz Miskiewicz
1527 - documented the -p option in useradd.8 and usermod.8 man pages
1528 - some "const" gcc warning fixes
1529 - attempt to fix lib/snprintf.c compilation problems
1530 - added restart/reload/force-reload to /etc/init.d/logoutd (found by lintian)
1531 - always require password for root logins (even with NO_PASSWORD_CONSOLE)
1532 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1533 - changed to Y2K compatible version numbering
1534 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1535 values of user-entered dates (you can still enter dates in any format
1536 supported by GNU date)
1537 - oops, added doc/README.nls to list of files to distribute
1538 - added missing sanitize_env() call to src/login.c
1539 - debian/rules installs /bin/login non-setuid by default, just in case...
1540 - build Debian packages with cracklib support (depends on cracklib-runtime)
1542 shadow-980724 => shadow-981228
1544 - login now clears the username in argv[] (in case someone types the
1545 password instead of username, by mistake)
1546 - i18n support, Greek translation (Nikos Mavroyanopoulos), see README.nls
1547 - updated author's e-mail address (jfh@tab.com -> jfh@bga.com)
1548 - new getpass() replacement that displays *'s (Pavel Machek)
1549 - no password required when logging in from ttys listed under
1550 NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
1551 - fixed limits code so RLIMIT_AS should work
1552 - upgraded to Debian 2.0
1553 - built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
1554 in reasonable time again
1555 - upgraded to automake-1.3, libtool-1.0h (also new config.guess and
1556 config.sub that work on i686)
1557 - usermod fixed to handle group names starting with digits (not recommended)
1559 shadow-980626 => shadow-980724
1561 - security: login no longer gives you a root shell if setgid()
1562 or initgroups() or setuid() fails for any reason, discovered
1563 by Ted Hickman <thickman@sy.net>
1564 - remove libshadow.so -> libshadow.so.x.x symlink after install
1565 - a few int -> uid_t type cleanups
1566 - fail immediately (don't retry) in *_lock() if euid != 0
1567 - added sample PAM config files etc/pam.d/{passwd,su}
1568 - preliminary PAM support in su (untested - use at your own risk,
1569 comments and patches welcome!)
1570 - cleanup and more comments in OPIE code (Algis Rudys)
1571 - added support for TCFS (Transparent Cryptographic File System)
1572 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/
1573 for more info), thanks to Aniello Del Sorbo
1575 shadow-980529 => shadow-980626
1577 - fixed bug in commonio_lock() (infinite recursion if lckpwdf() not
1578 used and database cannot be locked), thanks to Jonathan Hankins
1579 - fixed bug in copy_tree() (NUL-terminate readlink() results),
1580 thanks to Lutz Schwalowsky
1581 - no need to press Enter after Ctrl-C to interrupt password prompt
1582 - removed a few harmless gcc warnings
1583 - secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)
1584 - faillog.8: changed /usr/adm -> /var/log
1585 - pwconv.8: documented that it may fail on invalid password files
1587 shadow-980417 => shadow-980529
1589 - fixed "interesting" strzero() bug introduced by me in 980417:
1590 strzero(cp) didn't work as intended (the macro used a local
1591 variable called "cp" - oops...); Leonard N. Zubkoff was the
1592 first person to report it - thanks!
1593 - fixed usermod -e to accept empty argument (like useradd),
1594 thanks to Martin Bene
1595 - several changes from Debian 980403-0.2, see debian/changelog
1596 - added contrib/shadow-anonftp.patch (not yet merged, sorry...)
1597 thanks to Calle Karlsson
1599 shadow-980403 => shadow-980417
1601 - fixed login session limits (again - broken since 980130)
1602 - more symbolic constants for exit status values
1603 - fixed logoutd to work with 8-character usernames in utmp
1604 (no room for terminating NUL!)
1605 - various fixes to make the code more glibc2-friendly
1606 - updated doc/cracklib26.diff (fix for empty gecos, etc.)
1607 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1610 shadow-980130 => shadow-980403
1612 - security: su now creates the sulog file (if enabled and doesn't
1613 already exist) with umask 077
1614 - hopefully removed arbitrary group size limits (not yet for
1615 shadow groups though - sgetsgent() still needs a rewrite,
1616 but I don't want to delay this release any longer...)
1617 - fixed NULL dereference in groupmod -n
1619 shadow-971215 => shadow-980130
1621 - Debian binary packages can be built without root privileges
1622 (tar wrapper - debian/tar.c)
1623 - new subdir "redhat" (needs more work, see redhat/README)
1624 - in several places, exit(127) if exec fails with ENOENT, and
1625 exit(126) on other errors (as in ksh and bash)
1626 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1627 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1628 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1629 - handle crypt() returning NULL (possible according to Single Unix
1630 Spec) more gracefully (exit instead of SIGSEGV)
1631 - fixed bug in putgrent() that showed up when realloc() moved the
1632 buffer while expanding it, thanks to Floody <flood@evcom.net>
1633 - fixed bug in login session limits (with a limit set to N logins,
1634 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1635 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1636 - newer config.guess and config.sub (should work on x86 for x > 5)
1637 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1638 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1639 - documented more (not all yet) login.defs(5) settings
1640 - replaced more exit status numeric values with #defines
1641 - shadow-utils.spec now generated from shadow-utils.spec.in
1642 (so I don't have to edit version numbers for every new release)
1643 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1644 ("force" - exit(0) if the group already exists); other RedHat-
1645 specific options not added yet (best done in a perl script that
1646 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1647 - added -O option (override login.defs values) to useradd and groupadd
1648 - if usermod can't update the group file(s), exit(10) but update the
1649 password file(s) anyway (as documented by Solaris man page)
1650 - useradd should no longer set sp_expire to the current date (oops)
1651 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1652 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1653 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1654 detection, setpgrp vs. setpgid, other minor tweaks
1655 - various */Makefile.am tweaks
1656 - login.defs: added FAKE_SHELL - program to run instead of the login
1657 shell, with the real shell in argv[0] (Frank Denis)
1658 - login.defs: ignore case in yes/no settings
1659 - more E_* defines instead of hardcoded numbers for exit()
1660 - added sanitize_env() for setuid programs
1661 - login_desrpc() checks for getnetname() errors
1662 - new password is not "too similar" if it is long enough
1663 - replacement strstr() was static, no one noticed :-)
1664 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1665 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1666 - login sets $REMOTEHOST for remote logins
1667 - added newgrp -l option (Single Unix Spec, same as "-")
1668 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1669 200K of disk space on Linux/x86), enabled by default if supported by
1670 the system, use ./configure --disable-shared if it causes any problems.
1671 Warning: libshadow.so is intended for internal use by this package
1672 only - binary compatibility with future releases is not guaranteed.
1673 There should be no need to link any other programs with libshadow.so -
1674 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1675 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1676 version (!) - added check to configure; fixed do_pam_passwd prototype
1677 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1678 - added information about the new ftp site to doc/README.mirrors
1680 shadow-971001 => shadow-971215
1682 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1683 - updated the RPM .spec file
1684 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1685 (glibc defines something else named "rlogin" in utmpbits.h ?)
1686 - added MD5 checksums in Debian packages
1687 - added -p and -g options to vipw (edit the password or group file
1688 respectively, regardless of the command name in argv[0])
1689 - removed old DBM support (NDBM code is still there)
1690 - fixed a bug in gpasswd: current username was incorrectly identified as
1691 "root" because of setuid(0) done too early. It may be a security hole
1692 when using shadow groups - if "root" is listed as a group administrator,
1693 any user can add/remove members in that group. Thanks to Jesse Thilo.
1694 - gpasswd now logs which user (root or group admin) made the changes
1695 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1696 - newgrp and add_groups() allocate supplementary group lists dynamically
1697 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1698 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1699 changed by regular users (any combination of letters "frwh")
1700 - fixed contrib/pwdauth.c segfault with non-existent usernames
1701 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1702 - new date parsing code (from GNU date) used by useradd, usermod, chage
1703 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1704 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1705 - fixed useradd -G segfault (one '*' that shouldn't be there)
1706 - allow 8-bit characters in chfn
1707 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1708 - changed the handling of NIS plus entries in password files
1709 - some more tweaking in various debian/* files
1710 - logoutd uses getutent() instead of reading utmp file directly
1711 - fixed lckpwdf() called twice (and failing) when changing password
1712 if the user is not listed in /etc/shadow (Mike Pakovic)
1713 - erase and kill characters left unchanged if not defined in login.defs
1715 shadow-970616 => shadow-971001
1717 - Debian: mkpasswd no longer installed (dbm files not supported)
1718 - chpasswd checks for shadow/non-shadow at run time, too
1719 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1720 - changed libmisc/login_access.c as suggested by Dave Hagewood
1721 - replaced sprintf() with snprintf() in several places
1722 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1723 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1724 - non-root users can only run su with a terminal on stdin
1725 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1726 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1727 in libc, or system misconfiguration. Needs further investigation.
1728 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1729 - fixed free() called twice in libmisc/mail.c
1730 - added information about mirror sites (doc/README.mirrors)
1731 - updated pwconv.8 and pwunconv.8 man pages
1732 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1733 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1734 - corrected su.1 man page ($SHELL not used)
1735 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1736 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1737 - cleaned up PASS_MAX in getpass() (127 always assumed)
1738 - default editor for vipw changed from /bin/ae to a real editor :)
1740 shadow-970601 => shadow-970616
1742 - fixed execlp call (missing NULL) in src/vipw.c
1743 - vipw now preserves permissions on edited files
1744 - commented out the xdm-shadow hack in shadowconfig
1745 - improved RedHat spec file (Timo Karjalainen)
1746 - updated mailing list information
1747 - added information about the shadow paper (doc/README.shadow-paper)
1748 - renamed doc/console.c.spec (confused RPM)
1750 shadow-970502-2 => shadow-970601
1752 - fixed a typo in libmisc/mail.c causing login to segfault
1753 if MAIL_CHECK_ENAB=yes (sorry!)
1754 - patches for OPIE support (Algis Rudys) (untested)
1755 - programs that modify /etc/passwd or /etc/shadow will use
1756 lckpwdf() if available
1757 - now compiles with PAM support! (still untested)
1758 - cosmetic error message changes (prefixed by argv[0]:)
1760 shadow-970216 => shadow-970502-2
1762 - shadow group support fixes (grpconv didn't work - for some
1763 reason, putsgent() returns 1 instead of 0 on success;
1764 now -1 = failure, anything else = success)
1765 - upgraded to autoconf-2.12
1766 - pwconv and pwunconv now follow other UN*X systems and SVID3
1767 (modify files in place), original versions moved to "old"
1768 - scologin.c moved to "old" (it was only for SCO Xenix) so
1769 people stop sending patches for scologin.c gcc warnings :)
1770 - don't use the MD5* functions in libmisc/salt.c (glibc has
1771 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1772 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1773 - "passwd -S -a" now really works
1774 - support for Debian, vipw, a few fixes (Guy Maor)
1775 - src/login.c radius bug fix (Rafal Maszkowski)
1776 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1777 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1778 - limits.5 man page (Luca Berra)
1779 - expiry will work setgid shadow too, removed euid 0 check
1780 - added check for a64l() to configure (glibc)
1782 shadow-961025 => shadow-970216
1784 - major rewrite of *io.c (no more 4 copies of almost identical code)
1785 - use fsync() (if available) instead of sync() when updating password files
1786 - use fchmod() and fchown() if available
1787 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1788 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1789 - passwd -S -a: list information about all users (root only)
1790 - passwd -k: change only expired passwords
1791 - passwd -q: quiet mode
1792 - first attempt at PAM support in passwd
1793 - passwd updates the non-shadow password if /etc/shadow exists but the
1794 user has no shadow password
1795 - passwd logs who changed the password, added hook to allow non-root
1796 administrators who can change passwords (not implemented yet)
1797 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1798 - added -p (set encrypted password) option to useradd and usermod
1799 (idea from hpux10 - undocumented option used internally by SAM)
1800 - useradd -D -e does the right thing (set default expiration date)
1801 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1802 because there are just too many systems that need different commands
1803 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1804 faillog file format has been changed (somewhere between 960129 and
1805 960810), please truncate the old file (if any) to zero length
1806 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1807 - wtmp, lastlog, faillog file location guessed by configure
1808 - separate checks for invalid user and group names, max username length
1809 based on struct utmp (it's not always 8 characters)
1810 - pwck and grpck now check for invalid user/group names
1811 - pwck -q (quiet, report only serious problems) option added
1812 - separate cleaner sgetpwent() without the NIS magic
1813 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1814 - various code cleanups
1815 - new get_my_pwent() function for getting my own username, uid etc.
1816 - faillog opens the file read-write if possible (even if not root)
1817 - passwd -S allowed for normal users (for their own uid only)
1818 - handle the case of login denied to passwordless accounts better
1819 ("Login incorrect" without "Password:" prompt looks strange)
1820 - corrected author information and removed a copyright restriction
1822 shadow-960925 => shadow-961025
1824 - fixed a few typos in shadow group code
1825 - don't check for names starting with 'r' to determine if the shell
1826 is restricted, use /etc/shells instead (for the "rc" shell)
1827 - removed extra definition of LASTLOG_FILE in configure.in
1828 - expiry no longer segfaults if no /etc/shadow
1829 - userdel -r "can't remove mailbox" warning no longer printed on success
1830 - useradd exit codes changed to match hpux10 man page
1831 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1833 shadow-960920 => shadow-960925
1835 - bug fixes to the new environment code using malloc
1836 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1837 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1838 - small fix to isexpired(), and use it in passwd as well
1839 - use strftime() and strptime() if available
1840 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1841 contain encrypted passwords!)
1842 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1843 (nothing bad happened yet, just a cleanup)
1844 - gpasswd should work with both shadow and non-shadow group passwords
1845 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1846 - passwd -e for sunos4 (ATT_AGE), untested
1847 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1848 - small fix to l64a()
1849 - passwd prints a message after password successfully changed (for things
1850 like poppassd which run passwd and expect some output)
1851 - passwd logs if password was changed by root (as opposed to a luser)
1852 - passwd uses current uid if no username argument and getlogin() fails
1854 shadow-960910 => shadow-960920
1856 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1857 - newusers should work with both shadow and non-shadow passwords
1858 (still left to do: chpasswd, gpasswd)
1859 - login-static no longer compiled by default
1860 - more SYSLOG() macros
1862 shadow-960810 => shadow-960910
1864 - updated README.linux to point to the new ftp site
1865 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1866 - man pages now closer to LDP standards (Ivan Nejgebauer)
1867 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1868 - obscure.c fixed to compile with HAVE_LIBCRACK
1869 - cosmetic message changes in age.c
1870 - utmp open error check fixed in utmp.c
1871 - grpunconv added (Michael Meskes)
1872 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1873 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1874 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1875 - passwords can be changed if sp_max == -1 (now considered infinity)
1876 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1877 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1878 - contrib/rpasswd.c added (Joshua Cowan)
1879 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1880 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1881 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1883 shadow-960129 => shadow-960810
1885 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1886 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1887 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1888 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1889 - hopefully removed all the rcsid warnings
1890 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1891 - resource limits (Cristian Gafton)
1892 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1893 - more fixes in man pages
1894 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1895 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1896 su, useradd, userdel, usermod) should now work with both shadow and
1897 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1898 run time); a few programs still left to do
1899 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1900 - new contrib/adduser.c from Chris Evans
1901 - lots of other minor changes
1902 - source tree reorganization, GNU autoconf, portability cleanups
1903 - basename() renamed to Basename() to avoid name space confusion
1904 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1905 - newgrp cleanup and a few fixes
1906 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1907 - don't make the first group member the group admin by default
1908 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1909 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1910 place (defines.h) instead of repeating it in all source files...
1911 - added userdel -r safety check (refuse to remove the home directory
1912 if it would result in removing some other user's home directory)
1913 - usermod -u now correctly checks for non-unique uid (unless -o)
1914 - sync() after updating password files, just to be more safe
1915 - "make install" should install /etc/login.defs if it doesn't exist
1916 - new option to control what happens if we can't cd to the home directory
1917 (DEFAULT_HOME in /etc/login.defs)
1918 - enter the home directory as the user, not as root (for NFS etc.)
1919 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1920 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1921 possible to add specified groups (floppy etc.) for console logins
1922 - new faillog feature: lock account for specified (per-user) time since
1923 the last failure after exceeding the failure limit
1924 - new man pages (gpasswd.1, login.access.5, suauth.5)
1925 - fixes in man pages, renamed *.4 to *.5
1926 - new "contrib" directory (two adduser programs)
1927 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1928 - sulogin no longer requires to be run from init, should work from rc
1930 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1931 using xx_locate(), modify it and call xx_update(), don't write back
1932 anything returned by getpwnam() etc.)
1933 - stupid bug fixed in lastlog.c
1934 - don't move non-directories in "usermod -m"
1935 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1936 - macros to get around ancient compilers which don't like prototypes
1937 - make more use of "const" (not everywhere yet)
1938 - added #ifdef AUTH_METHODS - very few people use administrator defined
1939 authentication methods because many programs are not aware of them;
1940 not supporting them makes the code simpler
1941 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1942 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1943 see HAVE_SGETGRENT in config.h (grent.c)
1944 - don't use continued lines in /etc/group, the standard getgr*() functions
1945 don't support that (grent.c)
1946 - removed the third main() argument (according to libc docs, not allowed by
1947 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1948 - login access control (lmain.c, login_access.c)
1949 - added copyright notice to login_access.c (from logdaemon-5.0)
1950 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1951 - added closelog() in su before executing the shell (smain.c)
1952 - getting current user name changed (smain.c)
1953 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1954 - getpass() shouldn't return NULL except on errors (getpass.c)
1955 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1956 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1957 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1958 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1959 - "no shadow password" not logged, the same /bin/login should work with both
1960 shadow and non-shadow passwords (lmain.c)
1961 - some cleanup in various places (lmain.c, passwd.c)
1962 - new program to verify username/password pairs, for xlock etc.; it is not
1963 installed by default, read the comments first (pwdauth.c)
1964 - authentication programs run with empty environment for safety (pwauth.c)
1965 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1966 - common code separated from *io.c (commonio.c)
1967 - ownership and permissions on password files are now preserved (we may try
1968 to make more use of setgid and setuid non-root programs in the future)
1969 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1970 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
1971 - termios/termio/sgtty macros cleaned up a bit
1973 shadow-951218 => shadow-960129
1975 Emergency bug fix release - no new features since 951218. There are many
1976 new changes, but this bug really can't wait until they are tested.
1978 Probably all previous versions of the shadow suite have a serious bug which
1979 makes it possible to overwrite the stack by entering very long username at
1980 the login prompt. This can give root access to any remote user!
1982 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
1983 size of the array in lmain.c). Aaargh!!!
1985 shadow-951203 => shadow-951218
1988 - Linux utmp handling fixes (utmp.c)
1989 - last failure date printing fixes (failure.c)
1990 - minor fix to compile with USE_CRACKLIB (obscure.c)
1991 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
1992 - basename.c added, replacing duplicated code in various places
1993 - "su -" runs the shell with '-' in argv[0] again (smain.c)
1994 - removing at/cron jobs cleaned up (userdel.c)
1995 - /etc/gshadow should not be world-readable (sgroupio.c)
1996 - if fflush() failed, files were not closed (*io.c)
1997 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
1998 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
1999 - some minor cleanups for gcc -Wall (unused variables etc.)
2000 - removed README.FIRST (copyrights are OK now)
2001 - updated ANNOUNCE, README.linux, WISHLIST
2002 - as suggested, converted to RCS
2004 shadow-3.3.2-951127 => shadow-951203-jfh
2007 - Added the BSD-style copyright to all of the files. Any files with the
2008 old copyright have multiple copyright holders and need to be cleanroomed
2009 to produce BSD-style copyrightable files, or I need to get the consent
2010 of the others to change the copyright.
2011 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
2012 that all of the files should have the correct copyright there is no need
2013 to refer to that e-mail message.
2014 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
2015 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
2017 jfh@rpp386.cactus.org
2019 shadow-3.3.2-951106 => shadow-951127
2021 Note: for now this code only supports Linux. All the #ifdef's are there
2022 (and will be; support for at least SunOS 4.1.x would be nice) but:
2023 - I had to fix some potential security problems resulting from sloppy
2024 coding (no bounds checking), and it was easier for me to use snprintf()
2025 (not available on many systems, unfortunately), I'll fix that later.
2026 Old versions of Linux libc don't have snprintf() either, and the one
2027 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
2028 - I am lazy and only updated Makefile.linux and config.h.linux this time
2029 - I don't have root access to non-Linux systems (this means no testing)
2030 - this code needs some major reorganization, which will (hopefully)
2034 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
2035 - login can be statically linked (not that I think it's a good idea, better
2036 fix the telnetd, but paranoid people will like it :-)
2037 - login is installed non-setuid by default
2038 - check for NULL from getpass()
2039 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
2040 - use standard "Password: " prompt by default (pwauth.c)
2041 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
2042 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
2043 - Linux has <lastlog.h>
2044 - print ll_host on Linux too (lmain.c)
2045 - size checking in various places (setuid root programs, argh!)
2046 - preserve TERM from getty (lmain.c)
2047 - don't ignore SIGHUP (lmain.c)
2048 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
2049 - remove LD_xxx (env.c)
2050 - use bzero() instead of memset() for BSD portability and less #ifdef's
2051 (if the system has no bzero(), implement it as a macro using memset())
2052 - the above fixes wrong order of memset() parameters (log.c)
2053 - use getutent/pututline instead of doing it by hand (utmp.c)
2054 - added the new settings to login.defs.linux
2055 - added login_access.c to the distribution (not used yet)
2059 shadow-3.3.2 => shadow-3.3.2-951106
2061 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
2062 - malloc/strdup error checking, hopefully no more core dumps...
2063 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
2064 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
2065 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
2066 - use POSIX termios whenever possible on Linux
2067 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
2068 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
2069 - login -h only for root (lmain.c)
2070 - login -r not needed for Linux (lmain.c)
2071 - sample login.defs modified for Linux (login.defs.linux)
2072 - swapped chfn USAGE and ADMUSAGE (chfn.c)
2073 - added -u to passwd usage (passwd.c)
2074 - no #! check necessary for Linux (shell.c)
2075 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
2076 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
2077 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
2078 can now be set in login.defs, old values are used as defaults (lmain.c)
2079 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
2080 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
2081 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
2082 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
2083 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
2084 - check for weak passwords too if previous password was empty (obscure.c)
2085 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
2086 - Linux has getusershell(), use it (chsh.c)
2087 - check if the new shell is executable by the user (chsh.c)
2088 - sleep before printing "Login incorrect", not the other way around (lmain.c)
2089 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
2090 - do "wheel group" more like BSD does (smain.c)
2091 - use getlogin() in su (smain.c)
2092 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
2093 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
2094 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
2095 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
2096 - LOGIN_STRING should work now (pwauth.c, getdef.c)
2097 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
2098 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
2099 not lost when you copy the right ones to Makefile and config.h
