48 - chpasswd
49 * PAM enabled versions: restore the -e option to allow restoring
50 passwords without knowing those passwords. Restore together the -m

92 list of TTYs.
93 * Fixed warning and support for CONSOLE_GROUPS for users member of more
94 than 16 groups.

119 * Add --root option.
120 * Add --selinux-user option.
121 - usermod
122 * Accept options in any order (username not necessarily at the end)
123 * When the shadow file exists but there are no shadow entries, an entry
124 is created if the password is changed and passwd requires a
125 shadow entry, or if aging features are used (-e or -f).
126 * Add --root option.
127 - su
128 * Document the su exit values.
129 * When su receives a signal, wait for the child to terminate (after
130 sending a SIGTERM), and kill it only if it did not terminate by itself.
131 No delay will be enforced if the child cooperates.
132 * Default ENV_SUPATH is /sbin:/bin:/usr/sbin:/usr/bin
133 * Fixed infinite loop when CONSOLE is configured with a colon-separated
134 list of TTYs.
135 * Fixed warning and support for CONSOLE_GROUPS for users member of more

165
166 shadow-4.1.4.2 -> shadow-4.1.4.3 2011-02-15
167
168 *** security
169 - CVE-2011-0721: An insufficient input sanitation in chfn can be exploited
170 to create users or groups in a NIS environment.
171
172 shadow-4.1.4.1 -> shadow-4.1.4.2 2009-07-24
173
174 - general
175 * Improved support for large groups (impacts most user/group management
176 tools).
177
178 - addition of system users or groups
179 * Speed improvement. This should be noticeable in case of LDAP configured
180 systems. This should impact useradd, groupadd, and newusers
181 * Since system accounts are allocated from SYS_?ID_MIN to SYS_?ID_MAX in
182 reverse order, accounts are packed close to SYS_?ID_MAX if SYS_?ID_MIN
183 is already used but there are still dome gaps.
184
185 - login
186 * Add support for shells being a shell script without a shebang.
187 - su
188 * Preserve the DISPLAY and XAUTHORITY environment variables. This was
189 only the case in the non PAM enabled versions.
190 * Add support for shells being a shell script without a shebang.
191
192 *** translation
193 * The Finnish translation of passwd(1) was outdated and is no more
194 distributed.
195
196 shadow-4.1.4 -> shadow-4.1.4.1 2009-05-22
197
198 - login
199 * Fix failures with empty usernames on non PAM versions.
200 * Fix CONSOLE (securetty) support on non PAM versions.
201 - newgrp
202 * Return the exit status of the child.
203 - userdel
204 * On Linux, do not check if an user is logged in with utmp, but check if
205 the user is running some processes.
206 * If not on Linux, continue to search for an utmp record, but make sure
207 the process recorded in the utmp entry is still running.
208 * Report failures to remove the user's mailbox
209 * When USERGROUPS_ENAB is enabled, remove the user's group when the
210 user was the only member.
211 * Do not fail when -r is used and the home directory does not exist.
212 - usermod
213 * Check if the user is busy when the user's UID, name or home directory
214 is changed.
215
216 shadow-4.1.3.1 -> shadow-4.1.4 2009-05-10
217
218 - packaging
219 * Enable --enable-account-tools-setuid by default for PAM builds.
220 * Add configure option --enable-utmpx, disabled by default to mimic
221 the previous behavior on Linux (where utmp and utmpx are identical).
222 * Fix build failure on non-PAM systems when --without-pam is not
223 specified.
224
225 - chpasswd
226 * Change the passwords using PAM. This permits to define the password
227 policy in a central place. The -c/--crypt-method, -e/--encrypted,
228 -m/--md5 and -s/--sha-rounds options are no more supported on PAM
229 enabled systems.
230 - grpck
231 * Warn if a group has an entry in group and gshadow, and the password
232 field in group is not 'x'.
233 - login
234 * Do not trust the current utmp entry's ut_line to set PAM_TTY. This could
235 lead to DOS attacks.
236 * (PAM) Even if the user was already authenticated (-f flag), ask the
237 user to update his authentication token if needed.
238 - lastlog
239 * Fix regression causing empty reports.
240 - newusers
241 * Change the passwords using PAM. This permits to define the password
242 policy in a central place. The -c/--crypt-method and -s/--sha-rounds
243 options are no more supported on PAM enabled systems.
244 - pwck
245 * Warn if an user has an entry in passwd and shadow, and the password
246 field in passwd is not 'x'.
247
248 *** translation
249 - Updated Czech translation
250 - Updated French translation
251 - Updated German translation
252 - Updated Japanese translation
253 - Updated Korean translation
254 - Updated Portuguese translation
255 - Updated Russian translation
256
257 shadow-4.1.3 -> shadow-4.1.3.1 2009-04-15
258
259 *** security:
260 - Due to bad parsing of octal permissions, the permissions on tty (login)
261 but also UMASK were set wrongly (and weirdly). Only shadow-4.1.3 was
262 affected.
263
264 *** general
265 - login
266 * Fix regression when no user is specified on the command line.
267 - userdel
268 * Fixed SE Linux support
269 - vipw
270 * SE Linux: Set the default context to the context of the file being
271 edited. This ensures that the backup file inherit from the file's
272 context.
273
274 *** translation
275 - Updated Norwegian Bokmål translation
276
277 shadow-4.1.2.2 -> shadow-4.1.3 2009-04-12
278
279 *** general:
280 - packaging
281 * Fixed support for OpenPAM.
282 * Fixed support for uclibc.
283 * Added configure --enable-account-tools-setuid (default) /
284 --disable-account-tools-setuid options. This permits to disable the
285 PAM authentication of the caller for chage, chgpasswd, chpasswd,
286 groupadd, groupdel, groupmod, newusers, useradd, userdel, and usermod.
287 This authentication is not necessary when these tools are not
288 installed setuid root.
289 * Added configure --with-group-name-max-length (default) /
290 --without-group-name-max-length options. This permits to configure the maximum length allowed for group names:
291 <no option> -> default of 16 (like today)
292 --with-group-name-max-length -> default of 16
293 --without-group-name-max-length -> no max length
294 --with-group-name-max-length=n > max is set to n
295 No sanity checking is performed on n so people could do
296 something neat like --with-group-name-max-length=MAX_INT
297 - addition of users or groups
298 * Speed improvement in case UID_MAX/SYS_UID_MAX/GID_MAX/SYS_GID_MAX is
299 used for an user/group. This should be noticeable in case of LDAP
300 configured systems. This should impact useradd, groupadd, and newusers
301 - error handling improvement
302 * Make sure errors and incomplete changes are reported to syslog and
303 audit in case of unexpected failures.
304 * Report system inconsistencies to syslog and audit.
305 * Only report success to syslog and audit if the changes are really
306 performed in the system databases.
307 This is still not complete.
308 - /etc/login.defs
309 * New CREATE_HOME variable to tell useradd to create a home directory by
310 default.
311 - Translations
312 * New Kazakh translation.
313 * Spanish manpages are no more distributed. They are outdated. Please
314 contact pkg-shadow-devel@lists.alioth.debian.org if you wish to
315 provide updates.
316
317 - faillog
318 * Accept users specified as a numerical UID, or ranges of users (-user,
319 user-, user1-user2).
320 * -l, -m, and -r now apply not only to existing users, but to all the
321 specified UIDs.
322 * Options can be specified in any order.
323 - gpasswd
324 * Added support for long options --add (-a), --delete (-d),
325 --remove-password (-r), --restrict (-R), --administrators (-A), and
326 --members (-M).
327 * Added support for usernames with arbitrary length.
328 * audit logging improvements.
329 * error handling improvement (see above).
330 * Log permission denied to syslog and audit.
331 - groupadd
332 * audit logging improvements.
333 * error handling improvement (see above).
334 * Speedup (see "addition of users or groups" above).
335 * do not create groups with GID set to (gid_t)-1.
336 * Allocate system group GIDs in reverse order. This could be useful
337 later to increase the static IDs range.
338 - groupdel
339 * audit logging improvements.
340 * error handling improvement (see above).
341 - groupmems
342 * Check if user exist before they are added to groups.
343 * Avoid segfault in case the specified group does not exist in /etc/group.
344 * Everybody is allowed to list the users of a group.
345 * /etc/group is open readonly when one just wants to list the users of a
346 group.
347 * Added syslog support.
348 * Use the groupmems PAM service name instead of groupmod.
349 * Fix segmentation faults when adding or removing users from a group.
350 * Added support for shadow groups.
351 * Added support long options --add (-a), --delete (-d), --purge (-p),
352 --list (-l), --group (-g).
353 - groupmod
354 * audit logging improvements.
355 * error handling improvement (see above).
356 * do not create groups with GID set to (gid_t)-1.
357 - grpck
358 * warn for groups with GID set to (gid_t)-1.
359 - login
360 * Restore the echoctl, echoke, onclr flags to the terminal termio flags.
361 Reset echoprt, noflsh, tostop. This behavior seems to have change by
362 mistake in earlier releases (4.0.8, for no obvious reason).
363 - newusers
364 * Implement the -r, --system option.
365 * Speedup (see "addition of users or groups" above).
366 * do not create users with UID set to (gid_t)-1.
367 * do not create groups with GID set to (gid_t)-1.
368 * Allocate system account UIDs/GIDs in reverse order. This could be useful
369 later to increase the static IDs range.
370 - passwd
371 * For compatibility with other passwd version, the --lock an --unlock
372 options do not lock or unlock the user account anymore. They only
373 lock or unlock the user's password.
374 - pwck
375 * warn for users with UID set to (uid_t)-1.
376 - su
377 * Preserve COLORTERM in addition to TERM when su is called with the -l
378 option.

384 * do not create users with UID set to (gid_t)-1.
385 * Added -Z option to map SELinux user for user's login.
386 * Allocate system user UIDs in reverse order. This could be useful
387 later to increase the static IDs range.
388 - userdel
389 * audit logging improvements.
390 * Do not fail if the removed user is not in the shadow database.
391 * When the user's group shall be removed, do not fail if this group is
392 not in the gshadow file.
393 * Delete the SELinux user mapping for user's login.
394 - usermod
395 * Allow adding LDAP users (or any user not present in the local passwd
396 file) to local groups

398 * Added -Z option to map SELinux user for user's login.
399
400 shadow-4.1.2.1 -> shadow-4.1.2.2 23-11-2008
401
402 *** security
403 - Fix a race condition in login that could lead to gaining ownership or
404 changing mode of arbitrary files.
405 - Fix a possible login DOS, which could be caused by injecting forged
406 entries in utmp.
407
408 shadow-4.1.2 -> shadow-4.1.2.1 26-06-2008
409
410 *** security
411 - Fix an "audit log injection" vulnerability in login.
412 This vulnerability makes it easier for attackers to hide activities by
413 modifying portions of log events, e.g. by appending an addr= statement
414 to the login name.
415
416 shadow-4.1.1 -> shadow-4.1.2 25-05-2008
417
418 *** security:
419 - generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
420 chgpasswd; and also passwd if configured without PAM support).
421 The number of rounds and number of salt bytes was fixed to their lower
422 allowed values (resp. configurable and 8), hence voiding some of the
423 advantages of this encryption method. Dictionary attacks with
424 precomputed tables were easier than expected, but still harder than with
425 the MD5 (or DES) methods.
426
427 *** general:
428 - packaging
429 * Distribute the chfn, chsh, and userdel PAM configuration file.
430 * Fix the detection of the audit, pam, and selinux library and header
431 file; and fail if the feature is requested but not present on the
432 system.
433 * Fix build failure when configured with audit support.
434 - chfn
435 * Allow non-US-ASCII characters in the GECOS fields ("name", "room
436 number", and "other info" fields).
437 - login
438 * Do not fail if a shell option, specified after --, has more than 2
439 letters.
440 - su
441 * If the SULOG_FILE does not exist when an su session is logged, make
442 sure the file is created with group root, instead of using the group
443 of the caller.
444 - vipw
445 * Resume properly after ^Z.
446
447 *** documentation:
448 - Document the -r, --system option in the useradd, groupadd, and newusers
449 manpages.
450 - Document the -c, --crypt-method and -s, --sha-rounds options in the
451 newusers manpage.
452 - Document the -k, --skel option in the useradd manpage.
453 - Tag the section which require --enable-shadowgrp or --with-sha-crypt
454 accordingly.
455
456 shadow-4.1.0 -> shadow-4.1.1 02-04-2008
457
458 *** general:
459 - security
460 * Do not seed the random number generator each time, and use the time in
461 microseconds to avoid having the same salt for different passwords
462 generated in the same second.
463 - packaging
464 * Do not install the shadow library per default.
465 - general
466 * Do not translate the messages sent to syslog. This avoids logging
467 PAM error messages in the users's locale.
468 - etc/login.defs
469 * Set GID_MIN to the same value as UID_MIN by default (1000).
470 * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
471 SYS_GID_MAX (999) for system accounts.
472 - etc/useradd
473 * /etc/default/useradd now defines HOME as /home to match FHS.
474 - chage
475 * Fix bug which forbid to set the aging information of an account with a
476 passwd entry, but no shadow entry.
477 - faillog
478 * faillog -r now only reset the entries of existing users. This makes
479 faillog faster.
480 - gpasswd
481 * Fix failures when the gshadow file is not present.
482 * When a password is moved to the gshadow file, use "x" instead of "!"
483 to indicate that the password is shadowed (consistency with grpconv).
484 * Make sure the group and gshadow files are unlocked on exit.
485 - groupadd
486 * New option -p/--password to specify an encrypted password.
487 * New option -r, --system for system accounts.
488 - groupdel
489 * Do not fail if the group does not exist in the gshadow file.
490 * Do not rewrite the group or gshadow file in case of error.
491 * Make sure the group and gshadow files are unlocked on exit.
492 * Fail if the system is not configured to support split groups and
493 different group entries have the name of the group to be deleted.
494 - groupmems
495 * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
496 - groupmod
497 * New option -p/--password to specify an encrypted password.
498 * Make sure the group and gshadow files are unlocked on exit.
499 * When the GID of a group is changed, update also the GID of the passwd
500 entries of the users whose primary group is the group being modified.
501 - grpck
502 * Fix logging of changes to syslog when a group file is provided,
503 without a gshadow file.
504 - lastlog
505 * Accept users specified as a numerical UID, or ranges of users (-user,
506 user-, user1-user2).
507 - login
508 * Use PATH and SUPATH to set the PATH environment variable, even when
509 support for PAM is enabled.
510 * If started as init, start a new session.
511 - newgrp
512 * Fix segfault when an user returns to an unknown GID (either the user
513 was deleted during the user's newgrp session or the user's passwd
514 entry referenced an invalid group). Add a syslog warning in that case.
515 * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
516 changing the user space group ID with newgrp or sg.
517 - newusers
518 * The new users are no more added to the list of members of their groups
519 because the membership is already set by their primary group.
520 * Added support for gshadow.
521 * Avoid using the same salt for different passwords.
522 * Fix support for the NONE crypt method.
523 * newusers will behave more like useradd regarding the choice of UID or
524 GID or regarding the validity of user and group names.
525 * New option -r, --system for system accounts.
526 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
527 exit.
528 - passwd
529 * Make sure that no more than one username argument was provided.
530 * Make SE Linux tests more strict, when the real UID is 0 SE Linux
531 checks will be performed.
532 - pwck
533 * Fix logging of changes to syslog when a passwd file is provided,
534 without a shadow file.
535 - su
536 * su's arguments are now reordered. If needed, use -- to separate su's
537 options from the shell's options.
538 - sulogin
539 * If started as init, start a new session.
540 - useradd
541 * New option -l to avoid adding the user to the lastlog and faillog databases.
542 * Fix the handling of the --defaults option (it required an argument,
543 but should behave as -D)
544 * Document the --defaults option, which was already described in the
545 useradd's Usage information.
546 * New option -r, --system for system accounts.
547 * New options -U, --user-group and -N, --no-user-group. These options
548 should replace nflg from the previous versions. Please set any -n
549 option to deprecated because its meaning differs from one distribution
550 to the other.
551 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
552 exit.
553 - usermod
554 * Keep the access and modification time of files when moving an user's home
555 directory.
556 * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
557 differ from the old ones. If a requested new value is equal to the old
558 one, no changes will be performed for that field. If no fields are
559 changed, usermod will exist successfully with a warning. This avoids
560 logging changes to syslog when there are actually no changes.
561 * Fix the handling of -a when a user is being renamed (with -l)
562 - vipw/vigr
563 * Recommend editing the shadowed (resp. regular) file if the regular (resp.
564 shadowed) file was edited.
565
566 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2007
567
568 *** security:
569 - chgpasswd
570 When compiled with PAM support, it used the chpasswd policy file instead
571 of the chgpasswd policy file. If an administrator added some restriction
572 to the chgpasswd policy file, they were not taken into account.
573
574 *** general:
575 - Add support for SHA256 and SHA512 encrypt methods (supported by new
576 libc).
577 - useradd: Allow non numerical group identifier to be specified with
578 useradd's -g option.
579 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
580 - newgrp: Do not give an indication that the group has no password. Ask
581 for the password, as if there were a password.
582 - The permissions of the suid binaries is now configurable in
583 src/Makefile.am. Note that changing the permissions is not recommended.
584 - newgrp.c: Declare the child and pid variable at the beginning of a block.
585 This fixes a compilation issue with gcc 2.95.
586 - login_nopam: Add support for systems with no innetgr(). On those
587 systems, username with an @ will be treated like any other username
588 (i.e. lookup in the local database for an user with an @). Thanks to
589 Mike Frysinger for the patch.
590 - Add support for uClibc with no l64a().
591 - userdel, usermod: Fix infinite loop caused by erroneous group file
592 containing two entries with the same name. (The fix strategy differs
593 from
594 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
595 - userdel: Abort if an error is detected while updating the passwd or group
596 databases. The passwd or group files will not be written.
597 - usermod: Update the group database before flushing the nscd caches.
598 - usermod: Make sure the group modifications will be allowed before
599 writing the passwd files.
600 - Flush the nscd tables using nscd -i instead of the private glibc socket.
601 - usermod: Make usermod options independent of the argument order.
602 - newgrp: Do not request a password when a user uses newgrp to switch to
603 her primary group.
604 - passwd: -l/-u options: edit the shadow account expiry field *in
605 addition* to editing the password field.
606 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
607 were always missing.
608 - su: Avoid terminating the PAM library in the forked child. This is done
609 later in the parent after closing the PAM session.
610 - userdel: Fix the homedir prefix checking.
611 - passwd, usermod: Refuse to unlock an account when it would result in a
612 passwordless account.
613 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
614 getgrgid(), and getspnam(). There should be no functional changes.
615 - gpasswd: Only read information from the local file group database. It
616 writes the changes in /etc/group and/or /etc/gshadow, but used to read
617 information from getgrnam (hence possibly from another group database).
618 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
619 better support for split groups. Be careful when using this variable:
620 not all tools support well split groups (in or out of the shadow
621 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
622 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
623 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
624 passwords.
625 - chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
626 -s/--sha-rounds to supersede the system default encryption algorithm.
627 - chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
628 will respect the system default configured in /etc/login.defs
629
630 *** documentation:
631 - Generate the translated manpages from PO at build time.
632 - The generated manpages will change depending on the configure options.
633 If you use different options than the one used for the distributed
634 archive, you should re-generate the manpages.
635 - login.defs should now describe all the variables.
636 - The tools' documentation details the login.defs variables they use.

708 - reverted using docbook.sourceforge.net in XSL url.
709
710 shadow-4.0.15 -> shadow-4.0.16 05-06-2006
711
712 *** general:
713 - userdel: better fix for old CERT VU#312962 (which was fixed in shadow 4.0.8):
714 fixed forgoten checking of the return value from fchown() before
715 proceeding with the fchmod() (based on Owl patch prepared by
716 Rafal Wojtczuk <nergal@owl.openwall.com>),
717 - userdel: use login.defs::MAIL_DIR instead hardcoded /var/mail in created
718 mailbox path (based on Owl fixes submited
719 by Solar Designer <solar@openwall.com>),
720 - by default do not use libshadow_getpass() as getpass() replacemement.
721 Use libshadow_getpass() only when S/KEY support is enabled.
722 Current glibc getpass() handles correctly longer than 8 characters
723 passwords and libshadow_getpass() is used only because libc getpass()
724 do not handles password prompting with echo enabled,
725 - move login.defs::MD5_CRYPT_ENAB to non-PAM part,
726 - userdel: rewrited for use getopt_log(),

823 - su: move exit() outside libmisc/shell.c::shell() for handle shell() errors
824 on higher level (now is better visable where some programs exit with 126
825 and 127 exit codes); added new shell() parameter (char *const envp[])
826 which allow fix preserving enviloment in su on using -p, (patch by
827 Alexander Gattin <xrgtn@yandex.ru>),
828 - su: added handle -c,--command option for GNU su compliance (merge

1155 useradd.
1156 Patch and comment by Koblinger Egmont <egmont@uhulinux.hu>:
1157 Only two arguments are passed to the open() call though it expects three
1158 because O_CREAT is present. Hence the permission of the file first becomes
1159 some random garbage found on the stack, and an attacker can perhaps open
1160 this file and hold it open for reading or writing before the proper
1161 fchmod() is executed. (Actually, we could also pass the final "mode" to
1162 the open() call and then save the consequent fchmod().)
1163 - SELinux changes: added changes in chage, chfn, chsh, passwd for allow
1164 construct more grained user password/accuunt properties on SELinux

1289 - removed old AUTH_METHODS dependent code,
1290 - chage: now all code depend on SHADOWPWD. If shadow will not be configured
1291 on autoconf level for using shadow possword chage is olny stub which

1299 - logoutd, userd: handle also utmpx if avalaile,
1300 - newgrp: fix for non-PAM version
1301 Use CLOSE_SESSIONS depending code only when USE_PAM.
1302 The problem was reported by Mattias Webjorn Eriksson using Slackware
1303 8.1 and reproduced it using slackware-current (9.0beta) (fix submited by
1304 Simon Williams <simon@no-dns-yet.org.uk>),
1305 - fix in too_many_failures() function: incorrect if() condition in non-PAM
1306 dependent code in fail login handling (fixed by Krzysztof

1328 man pages translations projects (this documents are not synced with
1329 current en version but you know .. "Documentations is lik sex. When it is
1330 good it very very good. Whet it is bad it is better than nothing."). Any
1331 changes for syncing this are welcome and for anyone who will want maintain
1332 this documents directly I can give cvs write access to project resources.
1333 - added new de translation (by Frank Schmid <frank@cs-schmid.de>).
1334 - fixed building --with-shared: swapped utent (in src/login.c and

1360 shadow-4.0.0-owl-chage-ro-no-lock.diff:
1361 Added locks which are needed when doing r/w accesses, not when running
1362 as root. If root does read-only, there's no lock needed. Added missing
1363 "#include <errno.h>" for above (me).
1364 shadow-4.0.0-owl-warnings.diff
1365 Olny one fix from this patch was aplayd because other was fixed few days
1366 before :)
1367 shadow-4.0.0-owl-check_names.diff
1368 Merge only prat this patch with checking login name matching; checking
1369 is login string isn't longer than possible it will be good prepare using
1370 probably _POSIX_LOGIN_NAME_MAX from <bits/posix1_lim.h>,
1371 shadow-4.0.0-owl-chage-drop-priv.diff
1372 shadow-4.0.0-owl-pam-auth.diff
1373 Merge part with reorder initialize PAM and checkin is chage is runed by

1387
1388 shadow-20001016 => shadow-4.0.0 06-01-2002
1389
1390 - fix bug discovered and fixed by Marcel Ritter
1391 <Marcel.Ritter@rrze.uni-erlangen.de>
1392 Due to a big buffer size in lib/commonio.c this error does only appear
1393 if a line gets longer than 4096 bytes (there are probably very few people
1394 stumbling across this).
1395 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
1396 #!/bin/sh
1397 typeset -i NUM
1398 NUM=0
1399 groupadd demogroup
1400 while [ $NUM -le 1000 ]; do
1401 useradd -g demogroup -G demogroup -p "NONE" user$NUM
1402 NUM=$NUM+1
1403 done
1404 - remove limit 32 to groups per user by (the same user can belong to
1405 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
1406 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
1407 NOTE: it probably need testing on other system for add
1408 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
1409 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
1410 - drop detecting is pam_strerror() need one or two arguments. Instead using
1411 PAM_STRERROR() macro use directly pam_strerror() function with two
1412 arguments. pam_strerror() with one argument is obsoleted,
1413 - adde ja man pages (probably some man pages need update),
1414 - much better automake support,
1415 - added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
1416 groupmod(8), shadow(5) (man pages for other nations also are welcome),
1417 - mamny small fixes and updates nad improvements in man pages,
1418 - aplayed Debian patch to man pages for shadowconfig,
1419 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
1420 patch).
1421
1422 shadow-20001012 -> shadow-20001016:
1423 - conditionaly disabled body reload_nscd() because not every
1424 version of nscd can handle it (this can be enabled by define
1425 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
1426 - fixes on autoconf/automake level for dist target,
1427 - Julianne F. Haugh new contact adress.
1428
1429 shadow-20000902 => shadow-20001012
1430
1431 - removed /redhat directory with obsoleted files (partialy rewrited spec
1432 file is now in root directory),
1433 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
1434 overwrite previously existing groups in adduser,
1435 - added PAM support for chage (bind to "chage" PAM config file) also
1436 added PAM support for all other small tools like chpasswd, groupadd,
1437 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
1438 "shadow" PAM config file) - this modificaytions mainly based on
1439 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
1440 - many small fixes and improvments in automake (mow "make dist"
1441 works correctly),
1442 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
1443
1444 shadow-20000826 => shadow-20000902
1445
1446 This is probably the last release from me.
1447 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
1448 Good luck!
1449
1450 (I'm still interested to know what is going on with this package,
1451 which is fairly important to many Linux distributions, so please
1452 Cc: marekm@linux.org.pl in any related discussions - just don't
1453 expect me to respond quickly...)
1454
1455 Previous warning still applies - be careful!
1456
1457 - applied some of the Red Hat patches (revised slightly), thanks to
1458 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
1459 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
1460 in glibc 2.1.x) after changing anything, add usermod -L and -U
1461 options, remove LOG_CONS from openlog(), chage -d and -E handles
1462 dates in yyyy-mm-dd format ('/' is not required)
1463 - various cleanups
1464
1465 shadow-19990827 => shadow-20000826
1466
1467 WARNING: this release is not tested (other than that it compiles for me),
1468 please be careful. Previous release was a year ago, so it is really time
1469 to release something and start looking for a new, better maintainer...
1470 (I've been extremely busy recently. Credit for most of the real work,
1471 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1472 who maintains this package for Debian.)
1473
1474 - merged most of the changes from Debian (not all of them yet, PAM support
1475 should be complete but is not tested - need to upgrade to potato first)
1476 - added Polish translations of manual pages from PLD
1477 - change sulog() to not depend on global variables oldname, name
1478 - try to not follow symbolic links when deleting files recursively
1479 in userdel (still not perfect, safest to do it in single user mode)
1480 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
1481 (a few ANSI C constructs were used already, and no one complained)
1482 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
1483
1484 shadow-19990709 => shadow-19990827

1488 - i18n: added Swedish translation by Kristoffer Brånemyr <ztion@swipnet.se>
1489 - logoutd no longer reads /etc/logoutd.mesg at startup - instead, read
1490 it when sending to luser's tty (no need to reload with SIGHUP)
1491 - added support for "usergroups" feature often found in Linux distributions
1492 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1493 username == groupname, then set umask to 002 instead of 022)
1494 - Debian: pwck and grpck are now run from a daily cron job (root will
1495 receive an e-mail if something is wrong), and at system startup
1496 - added support for setting umask in /etc/limits
1497 - when using OPIE, re-prompt with echo on after empty password was entered
1498 - GETPASS_ASTERISKS now run time configurable (login.defs)
1499 - getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
1500 - getpass() allows all input to be erased using Control-U, and beeps when
1501 too many characters are entered
1502 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1503 - Debian: tar wrapper no longer needed to build packages as non-root user
1504 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1505 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1506 dpkg-architecture, cross compilation, only build passwd, add
1507 etc/login.defs.hurd conffile, conditionalize CBAUD
1508 - newgrp sets $HOME before running the new shell
1509 - both "sg group command" (usage message) and "sg group -c command"
1510 (man page) work, updated both the usage message and the man page :)
1511 - i18n: added missing _() for some translatable strings
1512
1513 shadow-19990607 => shadow-19990709
1514
1515 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
1516 - fixed a bug in newgrp if the user is in >= 17 groups
1517 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1518 almost all programs need it if skey/opie support is enabled)
1519 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1520 - changed faillog to do something (assume -p) with no options specified
1521 - updated version of the udbachk passwd/shadow/group file integrity

1525
1526 - upgraded to libtool-1.2, latest config.{guess,sub}

1530 - added some braces to if/else to avoid egcs warnings
1531 - started adding PAM support to login (based on util-linux, not finished yet)
1532 - changed "!" to "x" for pw_passwd in src/newusers.c
1533 - a few more Y2K fixes
1534 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
1535 thanks to Sami Kerola
1536 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1537 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1538 - updated mailing list information (moved again, now hosted by SuSE),
1539 updated README.mirrors, other minor documentation updates
1540 - made getpass work with redirected stdin
1541 - new readpass echoing asterisks disabled by default by popular demand
1542 (can be enabled at compile time: ./configure --enable-readpass)
1543 - the random number of asterisks in readpass is now more random
1544 (random number generator initialization was missing)
1545 - commented out --enable-md5crypt (obsolete) in configure.in
1546 - when checking for libskey, link with -lcrypt if libcrypt is available
1547 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1548 - added Package/Version ident strings (so you can use the RCS "ident"
1549 command to check any binary, which version of shadow it comes from)
1550
1551 shadow-981228 => shadow-19990307

1561 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1562 - changed to Y2K compatible version numbering
1563 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1564 values of user-entered dates (you can still enter dates in any format
1565 supported by GNU date)
1566 - oops, added doc/README.nls to list of files to distribute
1567 - added missing sanitize_env() call to src/login.c
1568 - debian/rules installs /bin/login non-setuid by default, just in case...
1569 - build Debian packages with cracklib support (depends on cracklib-runtime)
1570
1571 shadow-980724 => shadow-981228
1572
1573 - login now clears the username in argv[] (in case someone types the
1574 password instead of username, by mistake)

1579 NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
1580 - fixed limits code so RLIMIT_AS should work
1581 - upgraded to Debian 2.0
1582 - built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
1583 in reasonable time again
1584 - upgraded to automake-1.3, libtool-1.0h (also new config.guess and
1585 config.sub that work on i686)
1586 - usermod fixed to handle group names starting with digits (not recommended)
1587
1588 shadow-980626 => shadow-980724
1589
1590 - security: login no longer gives you a root shell if setgid()
1591 or initgroups() or setuid() fails for any reason, discovered
1592 by Ted Hickman <thickman@sy.net>
1593 - remove libshadow.so -> libshadow.so.x.x symlink after install
1594 - a few int -> uid_t type cleanups
1595 - fail immediately (don't retry) in *_lock() if euid != 0

1600 - added support for TCFS (Transparent Cryptographic File System)
1601 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/

1603
1604 shadow-980529 => shadow-980626

1609 thanks to Lutz Schwalowsky
1610 - no need to press Enter after Ctrl-C to interrupt password prompt
1611 - removed a few harmless gcc warnings
1612 - secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)
1613 - faillog.8: changed /usr/adm -> /var/log
1614 - pwconv.8: documented that it may fail on invalid password files
1615
1616 shadow-980417 => shadow-980529
1617
1618 - fixed "interesting" strzero() bug introduced by me in 980417:
1619 strzero(cp) didn't work as intended (the macro used a local
1620 variable called "cp" - oops...); Leonard N. Zubkoff was the
1621 first person to report it - thanks!
1622 - fixed usermod -e to accept empty argument (like useradd),
1623 thanks to Martin Bene
1624 - several changes from Debian 980403-0.2, see debian/changelog

1633 (no room for terminating NUL!)
1634 - various fixes to make the code more glibc2-friendly
1635 - updated doc/cracklib26.diff (fix for empty gecos, etc.)
1636 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1637 (RH 5.0 updates)
1638
1639 shadow-980130 => shadow-980403
1640
1641 - security: su now creates the sulog file (if enabled and doesn't
1642 already exist) with umask 077
1643 - hopefully removed arbitrary group size limits (not yet for
1644 shadow groups though - sgetsgent() still needs a rewrite,
1645 but I don't want to delay this release any longer...)
1646 - fixed NULL dereference in groupmod -n
1647
1648 shadow-971215 => shadow-980130
1649
1650 - Debian binary packages can be built without root privileges
1651 (tar wrapper - debian/tar.c)
1652 - new subdir "redhat" (needs more work, see redhat/README)
1653 - in several places, exit(127) if exec fails with ENOENT, and
1654 exit(126) on other errors (as in ksh and bash)
1655 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1656 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1657 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1658 - handle crypt() returning NULL (possible according to Single Unix
1659 Spec) more gracefully (exit instead of SIGSEGV)
1660 - fixed bug in putgrent() that showed up when realloc() moved the
1661 buffer while expanding it, thanks to Floody <flood@evcom.net>
1662 - fixed bug in login session limits (with a limit set to N logins,
1663 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1664 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1665 - newer config.guess and config.sub (should work on x86 for x > 5)
1666 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1667 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1668 - documented more (not all yet) login.defs(5) settings
1669 - replaced more exit status numeric values with #defines
1670 - shadow-utils.spec now generated from shadow-utils.spec.in
1671 (so I don't have to edit version numbers for every new release)
1672 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1673 ("force" - exit(0) if the group already exists); other RedHat-
1674 specific options not added yet (best done in a perl script that
1675 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1676 - added -O option (override login.defs values) to useradd and groupadd
1677 - if usermod can't update the group file(s), exit(10) but update the
1678 password file(s) anyway (as documented by Solaris man page)
1679 - useradd should no longer set sp_expire to the current date (oops)
1680 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1681 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1682 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1683 detection, setpgrp vs. setpgid, other minor tweaks
1684 - various */Makefile.am tweaks
1685 - login.defs: added FAKE_SHELL - program to run instead of the login
1686 shell, with the real shell in argv[0] (Frank Denis)
1687 - login.defs: ignore case in yes/no settings
1688 - more E_* defines instead of hardcoded numbers for exit()
1689 - added sanitize_env() for setuid programs
1690 - login_desrpc() checks for getnetname() errors
1691 - new password is not "too similar" if it is long enough
1692 - replacement strstr() was static, no one noticed :-)
1693 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1694 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1695 - login sets $REMOTEHOST for remote logins
1696 - added newgrp -l option (Single Unix Spec, same as "-")
1697 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1698 200K of disk space on Linux/x86), enabled by default if supported by
1699 the system, use ./configure --disable-shared if it causes any problems.
1700 Warning: libshadow.so is intended for internal use by this package
1701 only - binary compatibility with future releases is not guaranteed.
1702 There should be no need to link any other programs with libshadow.so -
1703 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1704 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1705 version (!) - added check to configure; fixed do_pam_passwd prototype
1706 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1707 - added information about the new ftp site to doc/README.mirrors
1708
1709 shadow-971001 => shadow-971215
1710
1711 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1712 - updated the RPM .spec file
1713 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1714 (glibc defines something else named "rlogin" in utmpbits.h ?)
1715 - added MD5 checksums in Debian packages
1716 - added -p and -g options to vipw (edit the password or group file
1717 respectively, regardless of the command name in argv[0])
1718 - removed old DBM support (NDBM code is still there)
1719 - fixed a bug in gpasswd: current username was incorrectly identified as
1720 "root" because of setuid(0) done too early. It may be a security hole
1721 when using shadow groups - if "root" is listed as a group administrator,
1722 any user can add/remove members in that group. Thanks to Jesse Thilo.
1723 - gpasswd now logs which user (root or group admin) made the changes
1724 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1725 - newgrp and add_groups() allocate supplementary group lists dynamically
1726 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1727 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1728 changed by regular users (any combination of letters "frwh")
1729 - fixed contrib/pwdauth.c segfault with non-existent usernames
1730 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1731 - new date parsing code (from GNU date) used by useradd, usermod, chage
1732 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1733 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1734 - fixed useradd -G segfault (one '*' that shouldn't be there)
1735 - allow 8-bit characters in chfn
1736 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1737 - changed the handling of NIS plus entries in password files
1738 - some more tweaking in various debian/* files
1739 - logoutd uses getutent() instead of reading utmp file directly
1740 - fixed lckpwdf() called twice (and failing) when changing password
1741 if the user is not listed in /etc/shadow (Mike Pakovic)
1742 - erase and kill characters left unchanged if not defined in login.defs
1743
1744 shadow-970616 => shadow-971001
1745
1746 - Debian: mkpasswd no longer installed (dbm files not supported)
1747 - chpasswd checks for shadow/non-shadow at run time, too
1748 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1749 - changed libmisc/login_access.c as suggested by Dave Hagewood
1750 - replaced sprintf() with snprintf() in several places
1751 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1752 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1753 - non-root users can only run su with a terminal on stdin
1754 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1755 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1756 in libc, or system misconfiguration. Needs further investigation.
1757 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1758 - fixed free() called twice in libmisc/mail.c
1759 - added information about mirror sites (doc/README.mirrors)
1760 - updated pwconv.8 and pwunconv.8 man pages
1761 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1762 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1763 - corrected su.1 man page ($SHELL not used)
1764 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1765 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1766 - cleaned up PASS_MAX in getpass() (127 always assumed)
1767 - default editor for vipw changed from /bin/ae to a real editor :)
1768
1769 shadow-970601 => shadow-970616
1770
1771 - fixed execlp call (missing NULL) in src/vipw.c
1772 - vipw now preserves permissions on edited files
1773 - commented out the xdm-shadow hack in shadowconfig
1774 - improved RedHat spec file (Timo Karjalainen)
1775 - updated mailing list information
1776 - added information about the shadow paper (doc/README.shadow-paper)
1777 - renamed doc/console.c.spec (confused RPM)
1778
1779 shadow-970502-2 => shadow-970601
1780
1781 - fixed a typo in libmisc/mail.c causing login to segfault
1782 if MAIL_CHECK_ENAB=yes (sorry!)
1783 - patches for OPIE support (Algis Rudys) (untested)
1784 - programs that modify /etc/passwd or /etc/shadow will use
1785 lckpwdf() if available
1786 - now compiles with PAM support! (still untested)
1787 - cosmetic error message changes (prefixed by argv[0]:)
1788
1789 shadow-970216 => shadow-970502-2
1790
1791 - shadow group support fixes (grpconv didn't work - for some
1792 reason, putsgent() returns 1 instead of 0 on success;
1793 now -1 = failure, anything else = success)
1794 - upgraded to autoconf-2.12
1795 - pwconv and pwunconv now follow other UN*X systems and SVID3
1796 (modify files in place), original versions moved to "old"
1797 - scologin.c moved to "old" (it was only for SCO Xenix) so
1798 people stop sending patches for scologin.c gcc warnings :)
1799 - don't use the MD5* functions in libmisc/salt.c (glibc has
1800 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1801 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1802 - "passwd -S -a" now really works
1803 - support for Debian, vipw, a few fixes (Guy Maor)
1804 - src/login.c radius bug fix (Rafal Maszkowski)
1805 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1806 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1807 - limits.5 man page (Luca Berra)
1808 - expiry will work setgid shadow too, removed euid 0 check
1809 - added check for a64l() to configure (glibc)
1810
1811 shadow-961025 => shadow-970216
1812
1813 - major rewrite of *io.c (no more 4 copies of almost identical code)
1814 - use fsync() (if available) instead of sync() when updating password files
1815 - use fchmod() and fchown() if available
1816 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1817 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1818 - passwd -S -a: list information about all users (root only)
1819 - passwd -k: change only expired passwords
1820 - passwd -q: quiet mode
1821 - first attempt at PAM support in passwd
1822 - passwd updates the non-shadow password if /etc/shadow exists but the
1823 user has no shadow password
1824 - passwd logs who changed the password, added hook to allow non-root
1825 administrators who can change passwords (not implemented yet)
1826 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1827 - added -p (set encrypted password) option to useradd and usermod
1828 (idea from hpux10 - undocumented option used internally by SAM)
1829 - useradd -D -e does the right thing (set default expiration date)
1830 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1831 because there are just too many systems that need different commands
1832 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1833 faillog file format has been changed (somewhere between 960129 and
1834 960810), please truncate the old file (if any) to zero length
1835 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1836 - wtmp, lastlog, faillog file location guessed by configure
1837 - separate checks for invalid user and group names, max username length
1838 based on struct utmp (it's not always 8 characters)
1839 - pwck and grpck now check for invalid user/group names
1840 - pwck -q (quiet, report only serious problems) option added
1841 - separate cleaner sgetpwent() without the NIS magic
1842 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1843 - various code cleanups
1844 - new get_my_pwent() function for getting my own username, uid etc.
1845 - faillog opens the file read-write if possible (even if not root)
1846 - passwd -S allowed for normal users (for their own uid only)
1847 - handle the case of login denied to passwordless accounts better
1848 ("Login incorrect" without "Password:" prompt looks strange)
1849 - corrected author information and removed a copyright restriction
1850
1851 shadow-960925 => shadow-961025
1852
1853 - fixed a few typos in shadow group code
1854 - don't check for names starting with 'r' to determine if the shell
1855 is restricted, use /etc/shells instead (for the "rc" shell)
1856 - removed extra definition of LASTLOG_FILE in configure.in
1857 - expiry no longer segfaults if no /etc/shadow
1858 - userdel -r "can't remove mailbox" warning no longer printed on success
1859 - useradd exit codes changed to match hpux10 man page
1860 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1861
1862 shadow-960920 => shadow-960925
1863
1864 - bug fixes to the new environment code using malloc
1865 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1866 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1867 - small fix to isexpired(), and use it in passwd as well
1868 - use strftime() and strptime() if available
1869 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1870 contain encrypted passwords!)
1871 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1872 (nothing bad happened yet, just a cleanup)
1873 - gpasswd should work with both shadow and non-shadow group passwords
1874 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1875 - passwd -e for sunos4 (ATT_AGE), untested
1876 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1877 - small fix to l64a()
1878 - passwd prints a message after password successfully changed (for things
1879 like poppassd which run passwd and expect some output)
1880 - passwd logs if password was changed by root (as opposed to a luser)
1881 - passwd uses current uid if no username argument and getlogin() fails
1882
1883 shadow-960910 => shadow-960920
1884
1885 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1886 - newusers should work with both shadow and non-shadow passwords
1887 (still left to do: chpasswd, gpasswd)
1888 - login-static no longer compiled by default
1889 - more SYSLOG() macros
1890
1891 shadow-960810 => shadow-960910
1892
1893 - updated README.linux to point to the new ftp site
1894 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1895 - man pages now closer to LDP standards (Ivan Nejgebauer)
1896 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1897 - obscure.c fixed to compile with HAVE_LIBCRACK
1898 - cosmetic message changes in age.c
1899 - utmp open error check fixed in utmp.c
1900 - grpunconv added (Michael Meskes)
1901 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1902 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1903 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1904 - passwords can be changed if sp_max == -1 (now considered infinity)
1905 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1906 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1907 - contrib/rpasswd.c added (Joshua Cowan)
1908 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1909 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1910 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1911
1912 shadow-960129 => shadow-960810
1913
1914 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1915 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1916 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1917 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1918 - hopefully removed all the rcsid warnings
1919 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1920 - resource limits (Cristian Gafton)
1921 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1922 - more fixes in man pages
1923 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1924 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1925 su, useradd, userdel, usermod) should now work with both shadow and
1926 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1927 run time); a few programs still left to do
1928 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1929 - new contrib/adduser.c from Chris Evans
1930 - lots of other minor changes
1931 - source tree reorganization, GNU autoconf, portability cleanups
1932 - basename() renamed to Basename() to avoid name space confusion
1933 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1934 - newgrp cleanup and a few fixes
1935 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1936 - don't make the first group member the group admin by default
1937 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1938 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1939 place (defines.h) instead of repeating it in all source files...
1940 - added userdel -r safety check (refuse to remove the home directory
1941 if it would result in removing some other user's home directory)
1942 - usermod -u now correctly checks for non-unique uid (unless -o)
1943 - sync() after updating password files, just to be more safe
1944 - "make install" should install /etc/login.defs if it doesn't exist
1945 - new option to control what happens if we can't cd to the home directory
1946 (DEFAULT_HOME in /etc/login.defs)
1947 - enter the home directory as the user, not as root (for NFS etc.)
1948 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1949 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1950 possible to add specified groups (floppy etc.) for console logins
1951 - new faillog feature: lock account for specified (per-user) time since
1952 the last failure after exceeding the failure limit
1953 - new man pages (gpasswd.1, login.access.5, suauth.5)
1954 - fixes in man pages, renamed *.4 to *.5
1955 - new "contrib" directory (two adduser programs)
1956 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1957 - sulogin no longer requires to be run from init, should work from rc
1958 scripts too
1959 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1960 using xx_locate(), modify it and call xx_update(), don't write back
1961 anything returned by getpwnam() etc.)
1962 - stupid bug fixed in lastlog.c
1963 - don't move non-directories in "usermod -m"
1964 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1965 - macros to get around ancient compilers which don't like prototypes
1966 - make more use of "const" (not everywhere yet)
1967 - added #ifdef AUTH_METHODS - very few people use administrator defined
1968 authentication methods because many programs are not aware of them;
1969 not supporting them makes the code simpler
1970 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1971 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1972 see HAVE_SGETGRENT in config.h (grent.c)
1973 - don't use continued lines in /etc/group, the standard getgr*() functions
1974 don't support that (grent.c)
1975 - removed the third main() argument (according to libc docs, not allowed by
1976 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1977 - login access control (lmain.c, login_access.c)
1978 - added copyright notice to login_access.c (from logdaemon-5.0)
1979 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1980 - added closelog() in su before executing the shell (smain.c)
1981 - getting current user name changed (smain.c)
1982 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1983 - getpass() shouldn't return NULL except on errors (getpass.c)
1984 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1985 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1986 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1987 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1988 - "no shadow password" not logged, the same /bin/login should work with both
1989 shadow and non-shadow passwords (lmain.c)
1990 - some cleanup in various places (lmain.c, passwd.c)
1991 - new program to verify username/password pairs, for xlock etc.; it is not
1992 installed by default, read the comments first (pwdauth.c)
1993 - authentication programs run with empty environment for safety (pwauth.c)
1994 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1995 - common code separated from *io.c (commonio.c)
1996 - ownership and permissions on password files are now preserved (we may try
1997 to make more use of setgid and setuid non-root programs in the future)
1998 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1999 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
2000 - termios/termio/sgtty macros cleaned up a bit
2001
2002 shadow-951218 => shadow-960129
2003
2004 Emergency bug fix release - no new features since 951218. There are many
2005 new changes, but this bug really can't wait until they are tested.
2006
2007 Probably all previous versions of the shadow suite have a serious bug which
2008 makes it possible to overwrite the stack by entering very long username at
2009 the login prompt. This can give root access to any remote user!
2010
2011 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
2012 size of the array in lmain.c). Aaargh!!!
2013
2014 shadow-951203 => shadow-951218
2015
2016 Changes:
2017 - Linux utmp handling fixes (utmp.c)
2018 - last failure date printing fixes (failure.c)
2019 - minor fix to compile with USE_CRACKLIB (obscure.c)
2020 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
2021 - basename.c added, replacing duplicated code in various places
2022 - "su -" runs the shell with '-' in argv[0] again (smain.c)
2023 - removing at/cron jobs cleaned up (userdel.c)
2024 - /etc/gshadow should not be world-readable (sgroupio.c)
2025 - if fflush() failed, files were not closed (*io.c)
2026 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
2027 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
2028 - some minor cleanups for gcc -Wall (unused variables etc.)
2029 - removed README.FIRST (copyrights are OK now)
2030 - updated ANNOUNCE, README.linux, WISHLIST
2031 - as suggested, converted to RCS
2032
2033 shadow-3.3.2-951127 => shadow-951203-jfh
2034
2035 Changes:
2036 - Added the BSD-style copyright to all of the files. Any files with the
2037 old copyright have multiple copyright holders and need to be cleanroomed
2038 to produce BSD-style copyrightable files, or I need to get the consent
2039 of the others to change the copyright.
2040 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
2041 that all of the files should have the correct copyright there is no need
2042 to refer to that e-mail message.
2043 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
2044 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
2045
2046 jfh@rpp386.cactus.org
2047
2048 shadow-3.3.2-951106 => shadow-951127
2049
2050 Note: for now this code only supports Linux. All the #ifdef's are there
2051 (and will be; support for at least SunOS 4.1.x would be nice) but:
2052 - I had to fix some potential security problems resulting from sloppy
2053 coding (no bounds checking), and it was easier for me to use snprintf()
2054 (not available on many systems, unfortunately), I'll fix that later.
2055 Old versions of Linux libc don't have snprintf() either, and the one
2056 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
2057 - I am lazy and only updated Makefile.linux and config.h.linux this time
2058 - I don't have root access to non-Linux systems (this means no testing)
2059 - this code needs some major reorganization, which will (hopefully)
2060 make porting easier
2061
2062 Changes:
2063 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
2064 - login can be statically linked (not that I think it's a good idea, better
2065 fix the telnetd, but paranoid people will like it :-)
2066 - login is installed non-setuid by default
2067 - check for NULL from getpass()
2068 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
2069 - use standard "Password: " prompt by default (pwauth.c)
2070 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
2071 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
2072 - Linux has <lastlog.h>
2073 - print ll_host on Linux too (lmain.c)
2074 - size checking in various places (setuid root programs, argh!)
2075 - preserve TERM from getty (lmain.c)
2076 - don't ignore SIGHUP (lmain.c)
2077 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
2078 - remove LD_xxx (env.c)
2079 - use bzero() instead of memset() for BSD portability and less #ifdef's
2080 (if the system has no bzero(), implement it as a macro using memset())
2081 - the above fixes wrong order of memset() parameters (log.c)
2082 - use getutent/pututline instead of doing it by hand (utmp.c)
2083 - added the new settings to login.defs.linux
2084 - added login_access.c to the distribution (not used yet)
2085
2086 ==========
2087
2088 shadow-3.3.2 => shadow-3.3.2-951106
2089
2090 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
2091 - malloc/strdup error checking, hopefully no more core dumps...
2092 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
2093 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
2094 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
2095 - use POSIX termios whenever possible on Linux
2096 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
2097 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
2098 - login -h only for root (lmain.c)
2099 - login -r not needed for Linux (lmain.c)
2100 - sample login.defs modified for Linux (login.defs.linux)
2101 - swapped chfn USAGE and ADMUSAGE (chfn.c)
2102 - added -u to passwd usage (passwd.c)
2103 - no #! check necessary for Linux (shell.c)
2104 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
2105 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
2106 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
2107 can now be set in login.defs, old values are used as defaults (lmain.c)
2108 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
2109 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
2110 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
2111 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
2112 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
2113 - check for weak passwords too if previous password was empty (obscure.c)
2114 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
2115 - Linux has getusershell(), use it (chsh.c)
2116 - check if the new shell is executable by the user (chsh.c)
2117 - sleep before printing "Login incorrect", not the other way around (lmain.c)
2118 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
2119 - do "wheel group" more like BSD does (smain.c)
2120 - use getlogin() in su (smain.c)
2121 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
2122 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
2123 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
2124 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
2125 - LOGIN_STRING should work now (pwauth.c, getdef.c)
2126 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
2127 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
2128 not lost when you copy the right ones to Makefile and config.h
2129
