3 shadow-4.1.3.1 -> shadow-4.1.3.2 UNRELEASED
6 * Enable --enable-account-tools-setuid by default for PAM builds.
7 * Add configure option --enable-utmpx, disabled by default to mimic
8 the previous behavior on Linux (where utmp and utmpx are identical).
9 * Fix build failure on non-PAM systems when --without-pam is not
13 * Change the passwords using PAM. This permits to define the password
14 policy in a central place. The -c/--crypt-method, -e/--encrypted,
15 -m/--md5 and -s/--sha-rounds options are no more supported on PAM
18 * Do not trust the current utmp entry's ut_line to set PAM_TTY. This could
20 * (PAM) Even if the user was already authenticated (-f flag), ask the
21 user to update his authentication token if needed.
23 * Fix regression causing empty reports.
25 * Change the passwords using PAM. This permits to define the password
26 policy in a central place. The -c/--crypt-method and -s/--sha-rounds
27 options are no more supported on PAM enabled systems.
30 - Updated Korean translation
31 - Updated Portuguese translation
33 shadow-4.1.3 -> shadow-4.1.3.1 2009-04-15
36 - Due to bad parsing of octal permissions, the permissions on tty (login)
37 but also UMASK were set wrongly (and weirdly). Only shadow-4.1.3 was
42 * Fix regression when no user is specified on the command line.
44 * Fixed SE Linux support
46 * SE Linux: Set the default context to the context of the file being
47 edited. This ensures that the backup file inherit from the file's
51 - Updated Norwegian Bokmål translation
53 shadow-4.1.2.2 -> shadow-4.1.3 2009-04-12
57 * Fixed support for OpenPAM.
58 * Fixed support for uclibc.
59 * Added configure --enable-account-tools-setuid (default) /
60 --disable-account-tools-setuid options. This permits to disable the
61 PAM authentication of the caller for chage, chgpasswd, chpasswd,
62 groupadd, groupdel, groupmod, newusers, useradd, userdel, and usermod.
63 This authentication is not necessary when these tools are not
64 installed setuid root.
65 * Added configure --with-group-name-max-length (default) /
66 --without-group-name-max-length options. This permits to configure the maximum length allowed for group names:
67 <no option> -> default of 16 (like today)
68 --with-group-name-max-length -> default of 16
69 --without-group-name-max-length -> no max length
70 --with-group-name-max-length=n > max is set to n
71 No sanity checking is performed on n so people could do
72 something neat like --with-group-name-max-length=MAX_INT
73 - addition of users or groups
74 * Speed improvement in case UID_MAX/SYS_UID_MAX/GID_MAX/SYS_GID_MAX is
75 used for an user/group. This should be noticeable in case of LDAP
76 configured systems. This should impact useradd, groupadd, and newusers
77 - error handling improvement
78 * Make sure errors and incomplete changes are reported to syslog and
79 audit in case of unexpected failures.
80 * Report system inconsistencies to syslog and audit.
81 * Only report success to syslog and audit if the changes are really
82 performed in the system databases.
83 This is still not complete.
85 * New CREATE_HOME variable to tell useradd to create a home directory by
88 * New Kazakh translation.
89 * Spanish manpages are no more distributed. They are outdated. Please
90 contact pkg-shadow-devel@lists.alioth.debian.org if you wish to
94 * Accept users specified as a numerical UID, or ranges of users (-user,
96 * -l, -m, and -r now apply not only to existing users, but to all the
98 * Options can be specified in any order.
100 * Added support for long options --add (-a), --delete (-d),
101 --remove-password (-r), --restrict (-R), --administrators (-A), and
103 * Added support for usernames with arbitrary length.
104 * audit logging improvements.
105 * error handling improvement (see above).
106 * Log permission denied to syslog and audit.
108 * audit logging improvements.
109 * error handling improvement (see above).
110 * Speedup (see "addition of users or groups" above).
111 * do not create groups with GID set to (gid_t)-1.
112 * Allocate system group GIDs in reverse order. This could be useful
113 later to increase the static IDs range.
115 * audit logging improvements.
116 * error handling improvement (see above).
118 * Check if user exist before they are added to groups.
119 * Avoid segfault in case the specified group does not exist in /etc/group.
120 * Everybody is allowed to list the users of a group.
121 * /etc/group is open readonly when one just wants to list the users of a
123 * Added syslog support.
124 * Use the groupmems PAM service name instead of groupmod.
125 * Fix segmentation faults when adding or removing users from a group.
126 * Added support for shadow groups.
127 * Added support long options --add (-a), --delete (-d), --purge (-p),
128 --list (-l), --group (-g).
130 * audit logging improvements.
131 * error handling improvement (see above).
132 * do not create groups with GID set to (gid_t)-1.
134 * warn for groups with GID set to (gid_t)-1.
136 * Restore the echoctl, echoke, onclr flags to the terminal termio flags.
137 Reset echoprt, noflsh, tostop. This behavior seems to have change by
138 mistake in earlier releases (4.0.8, for no obvious reason).
140 * Implement the -r, --system option.
141 * Speedup (see "addition of users or groups" above).
142 * do not create users with UID set to (gid_t)-1.
143 * do not create groups with GID set to (gid_t)-1.
144 * Allocate system account UIDs/GIDs in reverse order. This could be useful
145 later to increase the static IDs range.
147 * For compatibility with other passwd version, the --lock an --unlock
148 options do not lock or unlock the user account anymore. They only
149 lock or unlock the user's password.
151 * warn for users with UID set to (uid_t)-1.
153 * Preserve COLORTERM in addition to TERM when su is called with the -l
156 * audit logging improvements.
157 * Speedup (see "addition of users or groups" above).
158 * See CREATE_HOME above.
159 * New -M/--no-create-home option to disable CREATE_HOME.
160 * do not create users with UID set to (gid_t)-1.
161 * Added -Z option to map SELinux user for user's login.
162 * Allocate system user UIDs in reverse order. This could be useful
163 later to increase the static IDs range.
165 * audit logging improvements.
166 * Do not fail if the removed user is not in the shadow database.
167 * When the user's group shall be removed, do not fail if this group is
168 not in the gshadow file.
169 * Delete the SELinux user mapping for user's login.
171 * Allow adding LDAP users (or any user not present in the local passwd
172 file) to local groups
173 * do not create users with UID set to (gid_t)-1.
174 * Added -Z option to map SELinux user for user's login.
176 shadow-4.1.2.1 -> shadow-4.1.2.2 23-11-2008
179 - Fix a race condition in login that could lead to gaining ownership or
180 changing mode of arbitrary files.
181 - Fix a possible login DOS, which could be caused by injecting forged
184 shadow-4.1.2 -> shadow-4.1.2.1 26-06-2008
187 - Fix an "audit log injection" vulnerability in login.
188 This vulnerability makes it easier for attackers to hide activities by
189 modifying portions of log events, e.g. by appending an addr= statement
192 shadow-4.1.1 -> shadow-4.1.2 25-05-2008
195 - generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
196 chgpasswd; and also passwd if configured without PAM support).
197 The number of rounds and number of salt bytes was fixed to their lower
198 allowed values (resp. configurable and 8), hence voiding some of the
199 advantages of this encryption method. Dictionary attacks with
200 precomputed tables were easier than expected, but still harder than with
201 the MD5 (or DES) methods.
205 * Distribute the chfn, chsh, and userdel PAM configuration file.
206 * Fix the detection of the audit, pam, and selinux library and header
207 file; and fail if the feature is requested but not present on the
209 * Fix build failure when configured with audit support.
211 * Allow non-US-ASCII characters in the GECOS fields ("name", "room
212 number", and "other info" fields).
214 * Do not fail if a shell option, specified after --, has more than 2
217 * If the SULOG_FILE does not exist when an su session is logged, make
218 sure the file is created with group root, instead of using the group
221 * Resume properly after ^Z.
224 - Document the -r, --system option in the useradd, groupadd, and newusers
226 - Document the -c, --crypt-method and -s, --sha-rounds options in the
228 - Document the -k, --skel option in the useradd manpage.
229 - Tag the section which require --enable-shadowgrp or --with-sha-crypt
232 shadow-4.1.0 -> shadow-4.1.1 02-04-2008
236 * Do not seed the random number generator each time, and use the time in
237 microseconds to avoid having the same salt for different passwords
238 generated in the same second.
240 * Do not install the shadow library per default.
242 * Do not translate the messages sent to syslog. This avoids logging
243 PAM error messages in the users's locale.
245 * Set GID_MIN to the same value as UID_MIN by default (1000).
246 * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
247 SYS_GID_MAX (999) for system accounts.
249 * /etc/default/useradd now defines HOME as /home to match FHS.
251 * Fix bug which forbid to set the aging information of an account with a
252 passwd entry, but no shadow entry.
254 * faillog -r now only reset the entries of existing users. This makes
257 * Fix failures when the gshadow file is not present.
258 * When a password is moved to the gshadow file, use "x" instead of "x"
259 to indicate that the password is shadowed (consistency with grpconv).
260 * Make sure the group and gshadow files are unlocked on exit.
262 * New option -p/--password to specify an encrypted password.
263 * New option -r, --system for system accounts.
265 * Do not fail if the group does not exist in the gshadow file.
266 * Do not rewrite the group or gshadow file in case of error.
267 * Make sure the group and gshadow files are unlocked on exit.
268 * Fail if the system is not configured to support split groups and
269 different group entries have the name of the group to be deleted.
271 * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
273 * New option -p/--password to specify an encrypted password.
274 * Make sure the group and gshadow files are unlocked on exit.
275 * When the GID of a group is changed, update also the GID of the passwd
276 entries of the users whose primary group is the group being modified.
278 * Fix logging of changes to syslog when a group file is provided,
279 without a gshadow file.
281 * Accept users specified as a numerical UID, or ranges of users (-user,
284 * Use PATH and SUPATH to set the PATH environment variable, even when
285 support for PAM is enabled.
286 * If started as init, start a new session.
288 * Fix segfault when an user returns to an unknown GID (either the user
289 was deleted during the user's newgrp session or the user's passwd
290 entry referenced an invalid group). Add a syslog warning in that case.
291 * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
292 changing the user space group ID with newgrp or sg.
294 * The new users are no more added to the list of members of their groups
295 because the membership is already set by their primary group.
296 * Added support for gshadow.
297 * Avoid using the same salt for different passwords.
298 * Fix support for the NONE crypt method.
299 * newusers will behave more like useradd regarding the choice of UID or
300 GID or regarding the validity of user and group names.
301 * New option -r, --system for system accounts.
302 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
305 * Make sure that no more than one username argument was provided.
306 * Make SE Linux tests more strict, when the real UID is 0 SE Linux
307 checks will be performed.
309 * Fix logging of changes to syslog when a passwd file is provided,
310 without a shadow file.
312 * su's arguments are now reordered. If needed, use -- to separate su's
313 options from the shell's options.
315 * If started as init, start a new session.
317 * New option -l to avoid adding the user to the lastlog and faillog databases.
318 * Fix the handling of the --defaults option (it required an argument,
319 but should behave as -D)
320 * Document the --defaults option, which was already described in the
321 useradd's Usage information.
322 * New option -r, --system for system accounts.
323 * New options -U, --user-group and -N, --no-user-group. These options
324 should replace nflg from the previous versions. Please set any -n
325 option to deprecated because its meaning differs from one distribution
327 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
330 * Keep the access and modification time of files when moving an user's home
332 * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
333 differ from the old ones. If a requested new value is equal to the old
334 one, no changes will be performed for that field. If no fields are
335 changed, usermod will exist successfully with a warning. This avoids
336 logging changes to syslog when there are actually no changes.
337 * Fix the handling of -a when a user is being renamed (with -l)
339 * Recommend editing the shadowed (resp. regular) file if the regular (resp.
340 shadowed) file was edited.
342 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2007
346 When compiled with PAM support, it used the chpasswd policy file instead
347 of the chgpasswd policy file. If an administrator added some restriction
348 to the chgpasswd policy file, they were not taken into account.
351 - Add support for SHA256 and SHA512 encrypt methods (supported by new
353 - useradd: Allow non numerical group identifier to be specified with
355 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
356 - newgrp: Do not give an indication that the group has no password. Ask
357 for the password, as if there were a password.
358 - The permissions of the suid binaries is now configurable in
359 src/Makefile.am. Note that changing the permissions is not recommended.
360 - newgrp.c: Declare the child and pid variable at the beginning of a block.
361 This fixes a compilation issue with gcc 2.95.
362 - login_nopam: Add support for systems with no innetgr(). On those
363 systems, username with an @ will be treated like any other username
364 (i.e. lookup in the local database for an user with an @). Thanks to
365 Mike Frysinger for the patch.
366 - Add support for uClibc with no l64a().
367 - userdel, usermod: Fix infinite loop caused by erroneous group file
368 containing two entries with the same name. (The fix strategy differs
370 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
371 - userdel: Abort if an error is detected while updating the passwd or group
372 databases. The passwd or group files will not be written.
373 - usermod: Update the group database before flushing the nscd caches.
374 - usermod: Make sure the group modifications will be allowed before
375 writing the passwd files.
376 - Flush the nscd tables using nscd -i instead of the private glibc socket.
377 - usermod: Make usermod options independent of the argument order.
378 - newgrp: Do not request a password when a user uses newgrp to switch to
380 - passwd: -l/-u options: edit the shadow account expiry field *in
381 addition* to editing the password field.
382 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
384 - su: Avoid terminating the PAM library in the forked child. This is done
385 later in the parent after closing the PAM session.
386 - userdel: Fix the homedir prefix checking.
387 - passwd, usermod: Refuse to unlock an account when it would result in a
388 passwordless account.
389 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
390 getgrgid(), and getspnam(). There should be no functional changes.
391 - gpasswd: Only read information from the local file group database. It
392 writes the changes in /etc/group and/or /etc/gshadow, but used to read
393 information from getgrnam (hence possibly from another group database).
394 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
395 better support for split groups. Be careful when using this variable:
396 not all tools support well split groups (in or out of the shadow
397 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
398 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
399 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
401 - chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
402 -s/--sha-rounds to supersede the system default encryption algorithm.
403 - chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
404 will respect the system default configured in /etc/login.defs
407 - Generate the translated manpages from PO at build time.
408 - The generated manpages will change depending on the configure options.
409 If you use different options than the one used for the distributed
410 archive, you should re-generate the manpages.
411 - login.defs should now describe all the variables.
412 - The tools' documentation details the login.defs variables they use.
414 shadow-4.0.18.1 -> shadow-4.0.18.2 28-10-2007

424 when one of the -, -l, or --login options is set, even if called by root.
425 - limits: Support for 2 new resource limits: max nice value, and max real
426 time priority. The resource limits are not used when compiled with PAM.

444 (patch submitted by Mike Frysinger <vapier@gentoo.org>),
445 - groupadd, groupmod, useradd, usermod: fixed UID/GID overflow (fixed
446 http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=198920)
447 - passwd, useradd, usermod: fixed inactive/mindays/warndays/maxdays overflow
448 (simillar to RH#198920),

450 for build and install (patch by George Kraft <gk4@swbell.net>),
451 - S/Key: removed assign getpass() to libshadow_getpass() on autoconf level
452 (patch by Ulrich Mueller <ulm@kph.uni-mainz.de>; http://bugs.gentoo.org/139966),

466 - userdel, usermod: fixed segfault on remove home directory when it can't
467 be removed; for example when it is /dev/null (fixed http://bugs.gentoo.org/139148),
468 - improved SELinux detection on autoconf level (based on patch by
469 Dan Yefimov <dan@D00M.lightwave.net.ru>),
470 - removed using private implementation getpass() libc function
471 (now getpass() is used also when S/KEY support is enabled),
472 - move nologin do $(sbindir),
473 - useradd: fixed mail spool file creation (bug cached by Frans Pop
475 fixed http://bugs.debian.org/374705),

486 shadow-4.0.15 -> shadow-4.0.16 05-06-2006
489 - userdel: better fix for old CERT VU#312962 (which was fixed in shadow 4.0.8):
490 fixed forgoten checking of the return value from fchown() before
491 proceeding with the fchmod() (based on Owl patch prepared by
492 Rafal Wojtczuk <nergal@owl.openwall.com>),
493 - userdel: use login.defs::MAIL_DIR instead hardcoded /var/mail in created
494 mailbox path (based on Owl fixes submited
495 by Solar Designer <solar@openwall.com>),
496 - by default do not use libshadow_getpass() as getpass() replacemement.
497 Use libshadow_getpass() only when S/KEY support is enabled.
498 Current glibc getpass() handles correctly longer than 8 characters
499 passwords and libshadow_getpass() is used only because libc getpass()
500 do not handles password prompting with echo enabled,
501 - move login.defs::MD5_CRYPT_ENAB to non-PAM part,
502 - userdel: rewrited for use getopt_log(),
503 - install default/template configuration files:
504 -- if shadow is configured with use PAM install /etc/pam.d/* files,
505 -- if shadow do not uses PAM install /etc/{limits,login.acces} files,
506 -- install /etc/login.defs and /etc/default/useradd files,

512 on copy files (merge 482_libmisc_copydir_check_return_values Debian
514 - login, su (non-PAM variant): export MAIL only when MAIL_CHECK_ENAB
515 is enabled (Mike Frysinger <vapier@gentoo.org>),

519 by a signal which was not catched
520 (fixed by Eero Häkkinen <eero17@bigfoot.com>),

929 - remove handle login.defs::NOLOGIN_STR (never used),
930 - useradd: fixes a potential security problem when mailbox is created in
932 Patch and comment by Koblinger Egmont <egmont@uhulinux.hu>:
933 Only two arguments are passed to the open() call though it expects three
934 because O_CREAT is present. Hence the permission of the file first becomes
935 some random garbage found on the stack, and an attacker can perhaps open
936 this file and hold it open for reading or writing before the proper
937 fchmod() is executed. (Actually, we could also pass the final "mode" to
938 the open() call and then save the consequent fchmod().)
939 - SELinux changes: added changes in chage, chfn, chsh, passwd for allow
940 construct more grained user password/accuunt properties on SELinux
941 policies level. Patch originally based on RH changes (submited by Chris

1018 makes httpd Option SymlinkIfOwnerMatch break for default weg pages
1019 including symlinks placed into /etc/skel/public_html for example.
1020 http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=66819

1166 - fix bug discovered and fixed by Marcel Ritter
1167 <Marcel.Ritter@rrze.uni-erlangen.de>
1168 Due to a big buffer size in lib/commonio.c this error does only appear
1169 if a line gets longer than 4096 bytes (there are probably very few people
1170 stumbling across this).
1171 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
1176 while [ $NUM -le 1000 ]; do
1177 useradd -g demogroup -G demogroup -p "NONE" user$NUM
1180 - remove limit 32 to groups per user by (the same user can belong to
1181 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
1182 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)

1184 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
1185 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
1186 - drop detecting is pam_strerror() need one or two arguments. Instead using
1187 PAM_STRERROR() macro use directly pam_strerror() function with two
1188 arguments. pam_strerror() with one argument is obsoleted,
1189 - adde ja man pages (probably some man pages need update),
1190 - much better automake support,

1198 shadow-20001012 -> shadow-20001016:
1199 - conditionaly disabled body reload_nscd() because not every
1200 version of nscd can handle it (this can be enabled by define
1201 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
1202 - fixes on autoconf/automake level for dist target,
1203 - Julianne F. Haugh new contact adress.

1209 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
1210 overwrite previously existing groups in adduser,
1211 - added PAM support for chage (bind to "chage" PAM config file) also
1212 added PAM support for all other small tools like chpasswd, groupadd,
1213 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
1214 "shadow" PAM config file) - this modificaytions mainly based on
1215 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
1216 - many small fixes and improvments in automake (mow "make dist"
1218 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
1220 shadow-20000826 => shadow-20000902
1222 This is probably the last release from me.
1223 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
1226 (I'm still interested to know what is going on with this package,
1227 which is fairly important to many Linux distributions, so please
1228 Cc: marekm@linux.org.pl in any related discussions - just don't
1229 expect me to respond quickly...)
1231 Previous warning still applies - be careful!
1233 - applied some of the Red Hat patches (revised slightly), thanks to
1234 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
1235 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
1236 in glibc 2.1.x) after changing anything, add usermod -L and -U
1237 options, remove LOG_CONS from openlog(), chage -d and -E handles
1238 dates in yyyy-mm-dd format ('/' is not required)
1241 shadow-19990827 => shadow-20000826
1243 WARNING: this release is not tested (other than that it compiles for me),
1244 please be careful. Previous release was a year ago, so it is really time
1245 to release something and start looking for a new, better maintainer...
1246 (I've been extremely busy recently. Credit for most of the real work,
1247 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1248 who maintains this package for Debian.)
1250 - merged most of the changes from Debian (not all of them yet, PAM support
1251 should be complete but is not tested - need to upgrade to potato first)
1252 - added Polish translations of manual pages from PLD
1253 - change sulog() to not depend on global variables oldname, name
1254 - try to not follow symbolic links when deleting files recursively
1255 in userdel (still not perfect, safest to do it in single user mode)
1256 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
1257 (a few ANSI C constructs were used already, and no one complained)
1258 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
1260 shadow-19990709 => shadow-19990827

1266 it when sending to luser's tty (no need to reload with SIGHUP)
1267 - added support for "usergroups" feature often found in Linux distributions
1268 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1269 username == groupname, then set umask to 002 instead of 022)
1270 - Debian: pwck and grpck are now run from a daily cron job (root will
1271 receive an e-mail if something is wrong), and at system startup
1272 - added support for setting umask in /etc/limits
1273 - when using OPIE, re-prompt with echo on after empty password was entered
1274 - GETPASS_ASTERISKS now run time configurable (login.defs)
1275 - getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
1276 - getpass() allows all input to be erased using Control-U, and beeps when
1277 too many characters are entered
1278 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1279 - Debian: tar wrapper no longer needed to build packages as non-root user
1280 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1281 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1282 dpkg-architecture, cross compilation, only build passwd, add
1283 etc/login.defs.hurd conffile, conditionalize CBAUD
1284 - newgrp sets $HOME before running the new shell
1285 - both "sg group command" (usage message) and "sg group -c command"
1286 (man page) work, updated both the usage message and the man page :)
1287 - i18n: added missing _() for some translatable strings
1289 shadow-19990607 => shadow-19990709
1291 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
1292 - fixed a bug in newgrp if the user is in >= 17 groups
1293 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1294 almost all programs need it if skey/opie support is enabled)
1295 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1296 - changed faillog to do something (assume -p) with no options specified
1297 - updated version of the udbachk passwd/shadow/group file integrity
1298 checker (contrib/udbachk.v012.tgz)
1300 shadow-19990307 => shadow-19990607
1302 - upgraded to libtool-1.2, latest config.{guess,sub}
1303 - added missing #include "defines.h" in libmisc/login_desrpc.c - thanks
1304 to almost everyone for reporting it :-)

1306 - added some braces to if/else to avoid egcs warnings
1307 - started adding PAM support to login (based on util-linux, not finished yet)
1308 - changed "!" to "x" for pw_passwd in src/newusers.c
1309 - a few more Y2K fixes
1310 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
1311 thanks to Sami Kerola
1312 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1313 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1314 - updated mailing list information (moved again, now hosted by SuSE),
1315 updated README.mirrors, other minor documentation updates
1316 - made getpass work with redirected stdin
1317 - new readpass echoing asterisks disabled by default by popular demand
1318 (can be enabled at compile time: ./configure --enable-readpass)
1319 - the random number of asterisks in readpass is now more random
1320 (random number generator initialization was missing)
1321 - commented out --enable-md5crypt (obsolete) in configure.in
1322 - when checking for libskey, link with -lcrypt if libcrypt is available
1323 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1324 - added Package/Version ident strings (so you can use the RCS "ident"
1325 command to check any binary, which version of shadow it comes from)
1327 shadow-981228 => shadow-19990307
1329 - added support for setting process priority in /etc/limits
1330 - i18n: updated Greek translation

1332 - documented the -p option in useradd.8 and usermod.8 man pages
1333 - some "const" gcc warning fixes
1334 - attempt to fix lib/snprintf.c compilation problems
1335 - added restart/reload/force-reload to /etc/init.d/logoutd (found by lintian)
1336 - always require password for root logins (even with NO_PASSWORD_CONSOLE)
1337 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1338 - changed to Y2K compatible version numbering
1339 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1340 values of user-entered dates (you can still enter dates in any format
1341 supported by GNU date)
1342 - oops, added doc/README.nls to list of files to distribute
1343 - added missing sanitize_env() call to src/login.c
1344 - debian/rules installs /bin/login non-setuid by default, just in case...
1345 - build Debian packages with cracklib support (depends on cracklib-runtime)
1347 shadow-980724 => shadow-981228
1349 - login now clears the username in argv[] (in case someone types the
1350 password instead of username, by mistake)
1351 - i18n support, Greek translation (Nikos Mavroyanopoulos), see README.nls
1352 - updated author's e-mail address (jfh@tab.com -> jfh@bga.com)
1353 - new getpass() replacement that displays *'s (Pavel Machek)
1354 - no password required when logging in from ttys listed under
1355 NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
1356 - fixed limits code so RLIMIT_AS should work
1357 - upgraded to Debian 2.0
1358 - built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
1359 in reasonable time again
1360 - upgraded to automake-1.3, libtool-1.0h (also new config.guess and
1361 config.sub that work on i686)
1362 - usermod fixed to handle group names starting with digits (not recommended)
1364 shadow-980626 => shadow-980724
1366 - security: login no longer gives you a root shell if setgid()
1367 or initgroups() or setuid() fails for any reason, discovered
1368 by Ted Hickman <thickman@sy.net>
1369 - remove libshadow.so -> libshadow.so.x.x symlink after install
1370 - a few int -> uid_t type cleanups
1371 - fail immediately (don't retry) in *_lock() if euid != 0
1372 - added sample PAM config files etc/pam.d/{passwd,su}
1373 - preliminary PAM support in su (untested - use at your own risk,
1374 comments and patches welcome!)
1375 - cleanup and more comments in OPIE code (Algis Rudys)
1376 - added support for TCFS (Transparent Cryptographic File System)
1377 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/
1378 for more info), thanks to Aniello Del Sorbo
1380 shadow-980529 => shadow-980626
1382 - fixed bug in commonio_lock() (infinite recursion if lckpwdf() not
1383 used and database cannot be locked), thanks to Jonathan Hankins
1384 - fixed bug in copy_tree() (NUL-terminate readlink() results),
1385 thanks to Lutz Schwalowsky
1386 - no need to press Enter after Ctrl-C to interrupt password prompt
1387 - removed a few harmless gcc warnings
1388 - secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)
1389 - faillog.8: changed /usr/adm -> /var/log
1390 - pwconv.8: documented that it may fail on invalid password files
1392 shadow-980417 => shadow-980529
1394 - fixed "interesting" strzero() bug introduced by me in 980417:
1395 strzero(cp) didn't work as intended (the macro used a local
1396 variable called "cp" - oops...); Leonard N. Zubkoff was the
1397 first person to report it - thanks!
1398 - fixed usermod -e to accept empty argument (like useradd),
1399 thanks to Martin Bene
1400 - several changes from Debian 980403-0.2, see debian/changelog
1401 - added contrib/shadow-anonftp.patch (not yet merged, sorry...)
1402 thanks to Calle Karlsson
1404 shadow-980403 => shadow-980417
1406 - fixed login session limits (again - broken since 980130)
1407 - more symbolic constants for exit status values
1408 - fixed logoutd to work with 8-character usernames in utmp
1409 (no room for terminating NUL!)
1410 - various fixes to make the code more glibc2-friendly
1411 - updated doc/cracklib26.diff (fix for empty gecos, etc.)
1412 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1415 shadow-980130 => shadow-980403
1417 - security: su now creates the sulog file (if enabled and doesn't
1418 already exist) with umask 077
1419 - hopefully removed arbitrary group size limits (not yet for
1420 shadow groups though - sgetsgent() still needs a rewrite,
1421 but I don't want to delay this release any longer...)
1422 - fixed NULL dereference in groupmod -n
1424 shadow-971215 => shadow-980130
1426 - Debian binary packages can be built without root privileges
1427 (tar wrapper - debian/tar.c)
1428 - new subdir "redhat" (needs more work, see redhat/README)
1429 - in several places, exit(127) if exec fails with ENOENT, and
1430 exit(126) on other errors (as in ksh and bash)
1431 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1432 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1433 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1434 - handle crypt() returning NULL (possible according to Single Unix
1435 Spec) more gracefully (exit instead of SIGSEGV)
1436 - fixed bug in putgrent() that showed up when realloc() moved the
1437 buffer while expanding it, thanks to Floody <flood@evcom.net>
1438 - fixed bug in login session limits (with a limit set to N logins,
1439 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1440 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1441 - newer config.guess and config.sub (should work on x86 for x > 5)
1442 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1443 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1444 - documented more (not all yet) login.defs(5) settings
1445 - replaced more exit status numeric values with #defines
1446 - shadow-utils.spec now generated from shadow-utils.spec.in
1447 (so I don't have to edit version numbers for every new release)
1448 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1449 ("force" - exit(0) if the group already exists); other RedHat-
1450 specific options not added yet (best done in a perl script that
1451 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1452 - added -O option (override login.defs values) to useradd and groupadd
1453 - if usermod can't update the group file(s), exit(10) but update the
1454 password file(s) anyway (as documented by Solaris man page)
1455 - useradd should no longer set sp_expire to the current date (oops)
1456 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1457 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1458 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1459 detection, setpgrp vs. setpgid, other minor tweaks
1460 - various */Makefile.am tweaks
1461 - login.defs: added FAKE_SHELL - program to run instead of the login
1462 shell, with the real shell in argv[0] (Frank Denis)
1463 - login.defs: ignore case in yes/no settings
1464 - more E_* defines instead of hardcoded numbers for exit()
1465 - added sanitize_env() for setuid programs
1466 - login_desrpc() checks for getnetname() errors
1467 - new password is not "too similar" if it is long enough
1468 - replacement strstr() was static, no one noticed :-)
1469 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1470 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1471 - login sets $REMOTEHOST for remote logins
1472 - added newgrp -l option (Single Unix Spec, same as "-")
1473 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1474 200K of disk space on Linux/x86), enabled by default if supported by
1475 the system, use ./configure --disable-shared if it causes any problems.
1476 Warning: libshadow.so is intended for internal use by this package
1477 only - binary compatibility with future releases is not guaranteed.
1478 There should be no need to link any other programs with libshadow.so -
1479 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1480 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1481 version (!) - added check to configure; fixed do_pam_passwd prototype
1482 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1483 - added information about the new ftp site to doc/README.mirrors
1485 shadow-971001 => shadow-971215
1487 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1488 - updated the RPM .spec file
1489 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1490 (glibc defines something else named "rlogin" in utmpbits.h ?)
1491 - added MD5 checksums in Debian packages
1492 - added -p and -g options to vipw (edit the password or group file
1493 respectively, regardless of the command name in argv[0])
1494 - removed old DBM support (NDBM code is still there)
1495 - fixed a bug in gpasswd: current username was incorrectly identified as
1496 "root" because of setuid(0) done too early. It may be a security hole
1497 when using shadow groups - if "root" is listed as a group administrator,
1498 any user can add/remove members in that group. Thanks to Jesse Thilo.
1499 - gpasswd now logs which user (root or group admin) made the changes
1500 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1501 - newgrp and add_groups() allocate supplementary group lists dynamically
1502 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1503 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1504 changed by regular users (any combination of letters "frwh")
1505 - fixed contrib/pwdauth.c segfault with non-existent usernames
1506 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1507 - new date parsing code (from GNU date) used by useradd, usermod, chage
1508 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1509 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1510 - fixed useradd -G segfault (one '*' that shouldn't be there)
1511 - allow 8-bit characters in chfn
1512 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1513 - changed the handling of NIS plus entries in password files
1514 - some more tweaking in various debian/* files
1515 - logoutd uses getutent() instead of reading utmp file directly
1516 - fixed lckpwdf() called twice (and failing) when changing password
1517 if the user is not listed in /etc/shadow (Mike Pakovic)
1518 - erase and kill characters left unchanged if not defined in login.defs
1520 shadow-970616 => shadow-971001
1522 - Debian: mkpasswd no longer installed (dbm files not supported)
1523 - chpasswd checks for shadow/non-shadow at run time, too
1524 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1525 - changed libmisc/login_access.c as suggested by Dave Hagewood
1526 - replaced sprintf() with snprintf() in several places
1527 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1528 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1529 - non-root users can only run su with a terminal on stdin
1530 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1531 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1532 in libc, or system misconfiguration. Needs further investigation.
1533 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1534 - fixed free() called twice in libmisc/mail.c
1535 - added information about mirror sites (doc/README.mirrors)
1536 - updated pwconv.8 and pwunconv.8 man pages
1537 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1538 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1539 - corrected su.1 man page ($SHELL not used)
1540 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1541 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1542 - cleaned up PASS_MAX in getpass() (127 always assumed)
1543 - default editor for vipw changed from /bin/ae to a real editor :)
1545 shadow-970601 => shadow-970616
1547 - fixed execlp call (missing NULL) in src/vipw.c
1548 - vipw now preserves permissions on edited files
1549 - commented out the xdm-shadow hack in shadowconfig
1550 - improved RedHat spec file (Timo Karjalainen)
1551 - updated mailing list information
1552 - added information about the shadow paper (doc/README.shadow-paper)
1553 - renamed doc/console.c.spec (confused RPM)
1555 shadow-970502-2 => shadow-970601
1557 - fixed a typo in libmisc/mail.c causing login to segfault
1558 if MAIL_CHECK_ENAB=yes (sorry!)
1559 - patches for OPIE support (Algis Rudys) (untested)
1560 - programs that modify /etc/passwd or /etc/shadow will use
1561 lckpwdf() if available
1562 - now compiles with PAM support! (still untested)
1563 - cosmetic error message changes (prefixed by argv[0]:)
1565 shadow-970216 => shadow-970502-2
1567 - shadow group support fixes (grpconv didn't work - for some
1568 reason, putsgent() returns 1 instead of 0 on success;
1569 now -1 = failure, anything else = success)
1570 - upgraded to autoconf-2.12
1571 - pwconv and pwunconv now follow other UN*X systems and SVID3
1572 (modify files in place), original versions moved to "old"
1573 - scologin.c moved to "old" (it was only for SCO Xenix) so
1574 people stop sending patches for scologin.c gcc warnings :)
1575 - don't use the MD5* functions in libmisc/salt.c (glibc has
1576 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1577 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1578 - "passwd -S -a" now really works
1579 - support for Debian, vipw, a few fixes (Guy Maor)
1580 - src/login.c radius bug fix (Rafal Maszkowski)
1581 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1582 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1583 - limits.5 man page (Luca Berra)
1584 - expiry will work setgid shadow too, removed euid 0 check
1585 - added check for a64l() to configure (glibc)
1587 shadow-961025 => shadow-970216
1589 - major rewrite of *io.c (no more 4 copies of almost identical code)
1590 - use fsync() (if available) instead of sync() when updating password files
1591 - use fchmod() and fchown() if available
1592 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1593 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1594 - passwd -S -a: list information about all users (root only)
1595 - passwd -k: change only expired passwords
1596 - passwd -q: quiet mode
1597 - first attempt at PAM support in passwd
1598 - passwd updates the non-shadow password if /etc/shadow exists but the
1599 user has no shadow password
1600 - passwd logs who changed the password, added hook to allow non-root
1601 administrators who can change passwords (not implemented yet)
1602 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1603 - added -p (set encrypted password) option to useradd and usermod
1604 (idea from hpux10 - undocumented option used internally by SAM)
1605 - useradd -D -e does the right thing (set default expiration date)
1606 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1607 because there are just too many systems that need different commands
1608 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1609 faillog file format has been changed (somewhere between 960129 and
1610 960810), please truncate the old file (if any) to zero length
1611 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1612 - wtmp, lastlog, faillog file location guessed by configure
1613 - separate checks for invalid user and group names, max username length
1614 based on struct utmp (it's not always 8 characters)
1615 - pwck and grpck now check for invalid user/group names
1616 - pwck -q (quiet, report only serious problems) option added
1617 - separate cleaner sgetpwent() without the NIS magic
1618 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1619 - various code cleanups
1620 - new get_my_pwent() function for getting my own username, uid etc.
1621 - faillog opens the file read-write if possible (even if not root)
1622 - passwd -S allowed for normal users (for their own uid only)
1623 - handle the case of login denied to passwordless accounts better
1624 ("Login incorrect" without "Password:" prompt looks strange)
1625 - corrected author information and removed a copyright restriction
1627 shadow-960925 => shadow-961025
1629 - fixed a few typos in shadow group code
1630 - don't check for names starting with 'r' to determine if the shell
1631 is restricted, use /etc/shells instead (for the "rc" shell)
1632 - removed extra definition of LASTLOG_FILE in configure.in
1633 - expiry no longer segfaults if no /etc/shadow
1634 - userdel -r "can't remove mailbox" warning no longer printed on success
1635 - useradd exit codes changed to match hpux10 man page
1636 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1638 shadow-960920 => shadow-960925
1640 - bug fixes to the new environment code using malloc
1641 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1642 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1643 - small fix to isexpired(), and use it in passwd as well
1644 - use strftime() and strptime() if available
1645 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1646 contain encrypted passwords!)
1647 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1648 (nothing bad happened yet, just a cleanup)
1649 - gpasswd should work with both shadow and non-shadow group passwords
1650 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1651 - passwd -e for sunos4 (ATT_AGE), untested
1652 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1653 - small fix to l64a()
1654 - passwd prints a message after password successfully changed (for things
1655 like poppassd which run passwd and expect some output)
1656 - passwd logs if password was changed by root (as opposed to a luser)
1657 - passwd uses current uid if no username argument and getlogin() fails
1659 shadow-960910 => shadow-960920
1661 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1662 - newusers should work with both shadow and non-shadow passwords
1663 (still left to do: chpasswd, gpasswd)
1664 - login-static no longer compiled by default
1665 - more SYSLOG() macros
1667 shadow-960810 => shadow-960910
1669 - updated README.linux to point to the new ftp site
1670 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1671 - man pages now closer to LDP standards (Ivan Nejgebauer)
1672 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1673 - obscure.c fixed to compile with HAVE_LIBCRACK
1674 - cosmetic message changes in age.c
1675 - utmp open error check fixed in utmp.c
1676 - grpunconv added (Michael Meskes)
1677 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1678 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1679 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1680 - passwords can be changed if sp_max == -1 (now considered infinity)
1681 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1682 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1683 - contrib/rpasswd.c added (Joshua Cowan)
1684 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1685 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1686 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1688 shadow-960129 => shadow-960810
1690 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1691 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1692 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1693 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1694 - hopefully removed all the rcsid warnings
1695 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1696 - resource limits (Cristian Gafton)
1697 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1698 - more fixes in man pages
1699 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1700 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1701 su, useradd, userdel, usermod) should now work with both shadow and
1702 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1703 run time); a few programs still left to do
1704 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1705 - new contrib/adduser.c from Chris Evans
1706 - lots of other minor changes
1707 - source tree reorganization, GNU autoconf, portability cleanups
1708 - basename() renamed to Basename() to avoid name space confusion
1709 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1710 - newgrp cleanup and a few fixes
1711 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1712 - don't make the first group member the group admin by default
1713 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1714 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1715 place (defines.h) instead of repeating it in all source files...
1716 - added userdel -r safety check (refuse to remove the home directory
1717 if it would result in removing some other user's home directory)
1718 - usermod -u now correctly checks for non-unique uid (unless -o)
1719 - sync() after updating password files, just to be more safe
1720 - "make install" should install /etc/login.defs if it doesn't exist
1721 - new option to control what happens if we can't cd to the home directory
1722 (DEFAULT_HOME in /etc/login.defs)
1723 - enter the home directory as the user, not as root (for NFS etc.)
1724 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1725 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1726 possible to add specified groups (floppy etc.) for console logins
1727 - new faillog feature: lock account for specified (per-user) time since
1728 the last failure after exceeding the failure limit
1729 - new man pages (gpasswd.1, login.access.5, suauth.5)
1730 - fixes in man pages, renamed *.4 to *.5
1731 - new "contrib" directory (two adduser programs)
1732 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1733 - sulogin no longer requires to be run from init, should work from rc
1735 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1736 using xx_locate(), modify it and call xx_update(), don't write back
1737 anything returned by getpwnam() etc.)
1738 - stupid bug fixed in lastlog.c
1739 - don't move non-directories in "usermod -m"
1740 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1741 - macros to get around ancient compilers which don't like prototypes
1742 - make more use of "const" (not everywhere yet)
1743 - added #ifdef AUTH_METHODS - very few people use administrator defined
1744 authentication methods because many programs are not aware of them;
1745 not supporting them makes the code simpler
1746 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1747 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1748 see HAVE_SGETGRENT in config.h (grent.c)
1749 - don't use continued lines in /etc/group, the standard getgr*() functions
1750 don't support that (grent.c)
1751 - removed the third main() argument (according to libc docs, not allowed by
1752 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1753 - login access control (lmain.c, login_access.c)
1754 - added copyright notice to login_access.c (from logdaemon-5.0)
1755 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1756 - added closelog() in su before executing the shell (smain.c)
1757 - getting current user name changed (smain.c)
1758 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1759 - getpass() shouldn't return NULL except on errors (getpass.c)
1760 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1761 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1762 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1763 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1764 - "no shadow password" not logged, the same /bin/login should work with both
1765 shadow and non-shadow passwords (lmain.c)
1766 - some cleanup in various places (lmain.c, passwd.c)
1767 - new program to verify username/password pairs, for xlock etc.; it is not
1768 installed by default, read the comments first (pwdauth.c)
1769 - authentication programs run with empty environment for safety (pwauth.c)
1770 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1771 - common code separated from *io.c (commonio.c)
1772 - ownership and permissions on password files are now preserved (we may try
1773 to make more use of setgid and setuid non-root programs in the future)
1774 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1775 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
1776 - termios/termio/sgtty macros cleaned up a bit
1778 shadow-951218 => shadow-960129
1780 Emergency bug fix release - no new features since 951218. There are many
1781 new changes, but this bug really can't wait until they are tested.
1783 Probably all previous versions of the shadow suite have a serious bug which
1784 makes it possible to overwrite the stack by entering very long username at
1785 the login prompt. This can give root access to any remote user!
1787 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
1788 size of the array in lmain.c). Aaargh!!!
1790 shadow-951203 => shadow-951218
1793 - Linux utmp handling fixes (utmp.c)
1794 - last failure date printing fixes (failure.c)
1795 - minor fix to compile with USE_CRACKLIB (obscure.c)
1796 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
1797 - basename.c added, replacing duplicated code in various places
1798 - "su -" runs the shell with '-' in argv[0] again (smain.c)
1799 - removing at/cron jobs cleaned up (userdel.c)
1800 - /etc/gshadow should not be world-readable (sgroupio.c)
1801 - if fflush() failed, files were not closed (*io.c)
1802 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
1803 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
1804 - some minor cleanups for gcc -Wall (unused variables etc.)
1805 - removed README.FIRST (copyrights are OK now)
1806 - updated ANNOUNCE, README.linux, WISHLIST
1807 - as suggested, converted to RCS
1809 shadow-3.3.2-951127 => shadow-951203-jfh
1812 - Added the BSD-style copyright to all of the files. Any files with the
1813 old copyright have multiple copyright holders and need to be cleanroomed
1814 to produce BSD-style copyrightable files, or I need to get the consent
1815 of the others to change the copyright.
1816 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
1817 that all of the files should have the correct copyright there is no need
1818 to refer to that e-mail message.
1819 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
1820 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
1822 jfh@rpp386.cactus.org
1824 shadow-3.3.2-951106 => shadow-951127
1826 Note: for now this code only supports Linux. All the #ifdef's are there
1827 (and will be; support for at least SunOS 4.1.x would be nice) but:
1828 - I had to fix some potential security problems resulting from sloppy
1829 coding (no bounds checking), and it was easier for me to use snprintf()
1830 (not available on many systems, unfortunately), I'll fix that later.
1831 Old versions of Linux libc don't have snprintf() either, and the one
1832 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
1833 - I am lazy and only updated Makefile.linux and config.h.linux this time
1834 - I don't have root access to non-Linux systems (this means no testing)
1835 - this code needs some major reorganization, which will (hopefully)
1839 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
1840 - login can be statically linked (not that I think it's a good idea, better
1841 fix the telnetd, but paranoid people will like it :-)
1842 - login is installed non-setuid by default
1843 - check for NULL from getpass()
1844 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
1845 - use standard "Password: " prompt by default (pwauth.c)
1846 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
1847 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
1848 - Linux has <lastlog.h>
1849 - print ll_host on Linux too (lmain.c)
1850 - size checking in various places (setuid root programs, argh!)
1851 - preserve TERM from getty (lmain.c)
1852 - don't ignore SIGHUP (lmain.c)
1853 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
1854 - remove LD_xxx (env.c)
1855 - use bzero() instead of memset() for BSD portability and less #ifdef's
1856 (if the system has no bzero(), implement it as a macro using memset())
1857 - the above fixes wrong order of memset() parameters (log.c)
1858 - use getutent/pututline instead of doing it by hand (utmp.c)
1859 - added the new settings to login.defs.linux
1860 - added login_access.c to the distribution (not used yet)
1864 shadow-3.3.2 => shadow-3.3.2-951106
1866 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
1867 - malloc/strdup error checking, hopefully no more core dumps...
1868 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
1869 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
1870 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
1871 - use POSIX termios whenever possible on Linux
1872 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
1873 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
1874 - login -h only for root (lmain.c)
1875 - login -r not needed for Linux (lmain.c)
1876 - sample login.defs modified for Linux (login.defs.linux)
1877 - swapped chfn USAGE and ADMUSAGE (chfn.c)
1878 - added -u to passwd usage (passwd.c)
1879 - no #! check necessary for Linux (shell.c)
1880 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
1881 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
1882 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
1883 can now be set in login.defs, old values are used as defaults (lmain.c)
1884 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
1885 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
1886 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
1887 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
1888 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
1889 - check for weak passwords too if previous password was empty (obscure.c)
1890 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
1891 - Linux has getusershell(), use it (chsh.c)
1892 - check if the new shell is executable by the user (chsh.c)
1893 - sleep before printing "Login incorrect", not the other way around (lmain.c)
1894 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
1895 - do "wheel group" more like BSD does (smain.c)
1896 - use getlogin() in su (smain.c)
1897 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
1898 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
1899 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
1900 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
1901 - LOGIN_STRING should work now (pwauth.c, getdef.c)
1902 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
1903 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
1904 not lost when you copy the right ones to Makefile and config.h
