3 shadow-4.1.2.1 -> shadow-4.1.3 UNRELEASED
7 * Added support for OpenPAM.
9 * Implement the -r, --system option.
11 * Allow adding LDAP users (or any user not present in the local passwd
14 * Check if user exist before they are added to groups.
15 * Avoid segfault in case the specified group does not exist in /etc/group.
17 shadow-4.1.2 -> shadow-4.1.2.1 26-06-2008
20 - Fix an "audit log injection" vulnerability in login.
21 This vulnerability makes it easier for attackers to hide activities by
22 modifying portions of log events, e.g. by appending an addr= statement
25 shadow-4.1.1 -> shadow-4.1.2 25-05-2008
28 - generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
29 chgpasswd; and also passwd if configured without PAM support).
30 The number of rounds and number of salt bytes was fixed to their lower
31 allowed values (resp. configurable and 8), hence voiding some of the
32 advantages of this encryption method. Dictionary attacks with
33 precomputed tables were easier than expected, but still harder than with
34 the MD5 (or DES) methods.
38 * Distribute the chfn, chsh, and userdel PAM configuration file.
39 * Fix the detection of the audit, pam, and selinux library and header
40 file; and fail if the feature is requested but not present on the
42 * Fix build failure when configured with audit support.
44 * Allow non-US-ASCII characters in the GECOS fields ("name", "room
45 number", and "other info" fields).
47 * Do not fail if a shell option, specified after --, has more than 2
50 * If the SULOG_FILE does not exist when an su session is logged, make
51 sure the file is created with group root, instead of using the group
54 * Resume properly after ^Z.
57 - Document the -r, --system option in the useradd, groupadd, and newusers
59 - Document the -c, --crypt-method and -s, --sha-rounds options in the
61 - Document the -k, --skel option in the useradd manpage.
62 - Tag the section which require --enable-shadowgrp or --with-sha-crypt
65 shadow-4.1.0 -> shadow-4.1.1 02-04-2008
69 * Do not seed the random number generator each time, and use the time in
70 microseconds to avoid having the same salt for different passwords
71 generated in the same second.
73 * Do not install the shadow library per default.
75 * Do not translate the messages sent to syslog. This avoids logging
76 PAM error messages in the users's locale.
78 * Set GID_MIN to the same value as UID_MIN by default (1000).
79 * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
80 SYS_GID_MAX (999) for system accounts.
82 * /etc/default/useradd now defines HOME as /home to match FHS.
84 * Fix bug which forbid to set the aging information of an account with a
85 passwd entry, but no shadow entry.
87 * faillog -r now only reset the entries of existing users. This makes
90 * Fix failures when the gshadow file is not present.
91 * When a password is moved to the gshadow file, use "x" instead of "x"
92 to indicate that the password is shadowed (consistency with grpconv).
93 * Make sure the group and gshadow files are unlocked on exit.
95 * New option -p/--password to specify an encrypted password.
96 * New option -r, --system for system accounts.
98 * Do not fail if the group does not exist in the gshadow file.
99 * Do not rewrite the group or gshadow file in case of error.
100 * Make sure the group and gshadow files are unlocked on exit.
101 * Fail if the system is not configured to support split groups and
102 different group entries have the name of the group to be deleted.
104 * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
106 * New option -p/--password to specify an encrypted password.
107 * Make sure the group and gshadow files are unlocked on exit.
108 * When the GID of a group is changed, update also the GID of the passwd
109 entries of the users whose primary group is the group being modified.
111 * Fix logging of changes to syslog when a group file is provided,
112 without a gshadow file.
114 * Accept users specified as a numerical UID, or ranges of users (-user,
117 * Use PATH and SUPATH to set the PATH environment variable, even when
118 support for PAM is enabled.
119 * If started as init, start a new session.
121 * Fix segfault when an user returns to an unknown GID (either the user
122 was deleted during the user's newgrp session or the user's passwd
123 entry referenced an invalid group). Add a syslog warning in that case.
124 * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
125 changing the user space group ID with newgrp or sg.
127 * The new users are no more added to the list of members of their groups
128 because the membership is already set by their primary group.
129 * Added support for gshadow.
130 * Avoid using the same salt for different passwords.
131 * Fix support for the NONE crypt method.
132 * newusers will behave more like useradd regarding the choice of UID or
133 GID or regarding the validity of user and group names.
134 * New option -r, --system for system accounts.
135 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
138 * Make sure that no more than one username argument was provided.
139 * Make SE Linux tests more strict, when the real UID is 0 SE Linux
140 checks will be performed.
142 * Fix logging of changes to syslog when a passwd file is provided,
143 without a shadow file.
145 * su's arguments are now reordered. If needed, use -- to separate su's
146 options from the shell's options.
148 * If started as init, start a new session.
150 * New option -l to avoid adding the user to the lastlog and faillog databases.
151 * Fix the handling of the --defaults option (it required an argument,
152 but should behave as -D)
153 * Document the --defaults option, which was already described in the
154 useradd's Usage information.
155 * New option -r, --system for system accounts.
156 * New options -U, --user-group and -N, --no-user-group. These options
157 should replace nflg from the previous versions. Please set any -n
158 option to deprecated because its meaning differs from one distribution
160 * Make sure the passwd, group, shadow, and gshadow files are unlocked on
163 * Keep the access and modification time of files when moving an user's home
165 * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
166 differ from the old ones. If a requested new value is equal to the old
167 one, no changes will be performed for that field. If no fields are
168 changed, usermod will exist successfully with a warning. This avoids
169 logging changes to syslog when there are actually no changes.
170 * Fix the handling of -a when a user is being renamed (with -l)
172 * Recommend editing the shadowed (resp. regular) file if the regular (resp.
173 shadowed) file was edited.
175 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2007
179 When compiled with PAM support, it used the chpasswd policy file instead
180 of the chgpasswd policy file. If an administrator added some restriction
181 to the chgpasswd policy file, they were not taken into account.
184 - Add support for SHA256 and SHA512 encrypt methods (supported by new
186 - useradd: Allow non numerical group identifier to be specified with
188 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
189 - newgrp: Do not give an indication that the group has no password. Ask
190 for the password, as if there were a password.
191 - The permissions of the suid binaries is now configurable in
192 src/Makefile.am. Note that changing the permissions is not recommended.
193 - newgrp.c: Declare the child and pid variable at the beginning of a block.
194 This fixes a compilation issue with gcc 2.95.
195 - login_nopam: Add support for systems with no innetgr(). On those
196 systems, username with an @ will be treated like any other username
197 (i.e. lookup in the local database for an user with an @). Thanks to
198 Mike Frysinger for the patch.
199 - Add support for uClibc with no l64a().
200 - userdel, usermod: Fix infinite loop caused by erroneous group file
201 containing two entries with the same name. (The fix strategy differs
203 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
204 - userdel: Abort if an error is detected while updating the passwd or group
205 databases. The passwd or group files will not be written.
206 - usermod: Update the group database before flushing the nscd caches.
207 - usermod: Make sure the group modifications will be allowed before
208 writing the passwd files.
209 - Flush the nscd tables using nscd -i instead of the private glibc socket.
210 - usermod: Make usermod options independent of the argument order.
211 - newgrp: Do not request a password when a user uses newgrp to switch to
213 - passwd: -l/-u options: edit the shadow account expiry field *in
214 addition* to editing the password field.
215 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
217 - su: Avoid terminating the PAM library in the forked child. This is done
218 later in the parent after closing the PAM session.
219 - userdel: Fix the homedir prefix checking.
220 - passwd, usermod: Refuse to unlock an account when it would result in a
221 passwordless account.
222 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
223 getgrgid(), and getspnam(). There should be no functional changes.
224 - gpasswd: Only read information from the local file group database. It
225 writes the changes in /etc/group and/or /etc/gshadow, but used to read
226 information from getgrnam (hence possibly from another group database).
227 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
228 better support for split groups. Be careful when using this variable:
229 not all tools support well split groups (in or out of the shadow
230 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
231 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
232 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
234 - chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
235 -s/--sha-rounds to supersede the system default encryption algorithm.
236 - chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
237 will respect the system default configured in /etc/login.defs
240 - Generate the translated manpages from PO at build time.
241 - The generated manpages will change depending on the configure options.
242 If you use different options than the one used for the distributed
243 archive, you should re-generate the manpages.
244 - login.defs should now describe all the variables.
245 - The tools' documentation details the login.defs variables they use.

281 (simillar to RH#198920),
282 - groupmems: rewrited for use PAM and getopt_long() and now it is enabled
283 for build and install (patch by George Kraft <gk4@swbell.net>),
284 - S/Key: removed assign getpass() to libshadow_getpass() on autoconf level
285 (patch by Ulrich Mueller <ulm@kph.uni-mainz.de>; http://bugs.gentoo.org/139966),

296 shadow-4.0.16 -> shadow-4.0.17 10-07-2006
299 - userdel, usermod: fixed segfault on remove home directory when it can't
300 be removed; for example when it is /dev/null (fixed http://bugs.gentoo.org/139148),
301 - improved SELinux detection on autoconf level (based on patch by
302 Dan Yefimov <dan@D00M.lightwave.net.ru>),
303 - removed using private implementation getpass() libc function
304 (now getpass() is used also when S/KEY support is enabled),

323 fixed forgoten checking of the return value from fchown() before
324 proceeding with the fchmod() (based on Owl patch prepared by
325 Rafal Wojtczuk <nergal@owl.openwall.com>),
326 - userdel: use login.defs::MAIL_DIR instead hardcoded /var/mail in created
327 mailbox path (based on Owl fixes submited
328 by Solar Designer <solar@openwall.com>),
329 - by default do not use libshadow_getpass() as getpass() replacemement.
330 Use libshadow_getpass() only when S/KEY support is enabled.
331 Current glibc getpass() handles correctly longer than 8 characters
332 passwords and libshadow_getpass() is used only because libc getpass()
333 do not handles password prompting with echo enabled,
334 - move login.defs::MD5_CRYPT_ENAB to non-PAM part,
335 - userdel: rewrited for use getopt_log(),
336 - install default/template configuration files:
337 -- if shadow is configured with use PAM install /etc/pam.d/* files,
338 -- if shadow do not uses PAM install /etc/{limits,login.acces} files,
339 -- install /etc/login.defs and /etc/default/useradd files,
340 - fixed handle relative symlinks too in lib/commonio.c
341 (merge patch from Fedora),
342 - properly notify nscd to flush its cache
343 (https://bugzilla.redhat.com/bugzilla/186803),
344 - useradd, usermod: fixes for verify return values mkdir() and chown()
345 on copy files (merge 482_libmisc_copydir_check_return_values Debian

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

372 - install limits(5), login.access(5) and porttime(5) man pages only when
373 shadow is builded with PAM support disabled,
374 - passwd(1): better document how password strength is checked
375 (fixed http://bugs.debian.org/115380),
376 - usermod(8): added missing -a option description
377 (by Christian Perrier <bubulle@debian.org>),

393 - login: default UMASK if not specified in login.defs is 022 (pointed by
394 Peter Vrabec <pvrabec@redhat.com>),
395 - chgpasswd: new tool (by Jonas Meurer <mejo@debian.org>),
396 - lastlog: print the usage and exit if an additional argument is profided to
397 lastlog (merge 488_laslog_verify_arguments Debian patch),
398 - login, newgrp, nologin, su: do not link with libselinux (merge
399 490_link_selinux_only_when_needed Debian patch),
400 - chage, chfn, chsh, passwd: fixed confusing error message if /proc is not
401 mounted (http://bugs.debian.org/352494 patch Nicolas François
402 <nicolas.francois@centraliens.net>),
403 - login (merge 433_login_more_LOG_UNKFAIL_ENAB Debian patch):
404 - TOO MANY LOGIN... logged if PAM_MAXTRIES or failcount >= retries (was

408 - always prints the number of tries in the syslog entry.
409 - add special handling for PAM_ABORT
410 - add an entry to failog, as when USE_PAM is not defined. (#53164)
411 - changed pam_end to PAM_END. This is certainly was a mistake. PAM_END is
412 pam_close_seesion + pam_end. Here, the session is still not open, we
413 don't have to close it.
414 - a HAVE_PAM_FAIL_DELAY is missing,
415 - su: fixed pam session support (patch from Topi Miettinen; fixed #57526,
416 #55873, 57532 Debian bugs),
417 - userdel: user's group is already removed by update_groups().

431 -Werror (by Alexander Gattin <xrgtn@yandex.ru>),
432 - su: move exit() outside libmisc/shell.c::shell() for handle shell() errors
433 on higher level (now is better visable where some programs exit with 126
434 and 127 exit codes); added new shell() parameter (char *const envp[])
435 which allow fix preserving enviloment in su on using -p, (patch by
436 Alexander Gattin <xrgtn@yandex.ru>),
437 - su: added handle -c,--command option for GNU su compliance (merge
438 437_su_-c_option Debian patch),

448 (Tommi Vainikainen <thv+debian@iki.fi>),
449 - expiry(1), faillog(5), faillog(8), gpasswd(1), groupadd(8), groupdel(8),
450 logoutd(8), nologin(8), vipw(8): added new cs man pages, (by Miroslav Kure
451 <kurem@upcase.inf.upol.cz>)
452 - login.defs(5): default UMASK if not specified in login.defs is 022
453 (pointed by Peter Vrabec <pvrabec@redhat.com>),
454 - useradd(8): better document that -d will not add the user's home directory
455 if it does not already exist (http://bugs.debian.org/154996),
456 - nologin(8) man pages added (merge 478_nologin.8.xml Debian patch).
458 shadow-4.0.13 -> shadow-4.0.14 03-01-2006
461 - fixes in handling login.defs: $MAIL_FILE is used in userdel and usermod,
462 $MD5_CRYPT_ENAB is used by crypt_make_salt, which is used by chpasswd,
463 gpasswd and newusers.
464 Both variables moved to PAM not dependent (447_missing_login.defs_variables
466 - chage: fix chage display when the last change field is set to 0.
467 This is consistent with PAM (merge 427_chage_expiry_0 Debian patch),
468 - su: if an password is expired, su should propose to change this password
469 (fixed http://bugs.debian.org/321384),
470 - login: added auditing support (based on Fedora patch for login from util-linux),
471 - useradd: merge PUG fixes from RedHat patch,
472 - nologin: new program,

476 - userdel: fix incorrect audit record in userdel
477 (https://bugzilla.redhat.com/bugzilla/174392),
478 - userdel: remove the user's group unless it is not really a user-private group
479 for better PUG support (based on FC patch),
480 - userdel: make the -f option force the removal of the user's group (even if it
481 is the primary group of another user)

763 - useradd: fixes a potential security problem when mailbox is created in
765 Patch and comment by Koblinger Egmont <egmont@uhulinux.hu>:
766 Only two arguments are passed to the open() call though it expects three
767 because O_CREAT is present. Hence the permission of the file first becomes
768 some random garbage found on the stack, and an attacker can perhaps open
769 this file and hold it open for reading or writing before the proper
770 fchmod() is executed. (Actually, we could also pass the final "mode" to
771 the open() call and then save the consequent fchmod().)
772 - SELinux changes: added changes in chage, chfn, chsh, passwd for allow
773 construct more grained user password/accuunt properties on SELinux

811 (now --help otput can be displayd for users without lastlog
812 file read permission),
813 -- cleanups in lastlog(8) man page using the same style as in
816 -- switch chpasswd to use getopt_long() and adds a --md5 option

1000 <Marcel.Ritter@rrze.uni-erlangen.de>
1001 Due to a big buffer size in lib/commonio.c this error does only appear
1002 if a line gets longer than 4096 bytes (there are probably very few people
1003 stumbling across this).
1004 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
1009 while [ $NUM -le 1000 ]; do
1010 useradd -g demogroup -G demogroup -p "NONE" user$NUM
1013 - remove limit 32 to groups per user by (the same user can belong to
1014 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
1015 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
1016 NOTE: it probably need testing on other system for add
1017 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
1018 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
1019 - drop detecting is pam_strerror() need one or two arguments. Instead using
1020 PAM_STRERROR() macro use directly pam_strerror() function with two
1021 arguments. pam_strerror() with one argument is obsoleted,
1022 - adde ja man pages (probably some man pages need update),
1023 - much better automake support,
1024 - added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
1025 groupmod(8), shadow(5) (man pages for other nations also are welcome),
1026 - mamny small fixes and updates nad improvements in man pages,
1027 - aplayed Debian patch to man pages for shadowconfig,
1028 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
1031 shadow-20001012 -> shadow-20001016:
1032 - conditionaly disabled body reload_nscd() because not every
1033 version of nscd can handle it (this can be enabled by define
1034 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
1035 - fixes on autoconf/automake level for dist target,
1036 - Julianne F. Haugh new contact adress.

1041 file is now in root directory),
1042 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
1043 overwrite previously existing groups in adduser,
1044 - added PAM support for chage (bind to "chage" PAM config file) also
1045 added PAM support for all other small tools like chpasswd, groupadd,
1046 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
1047 "shadow" PAM config file) - this modificaytions mainly based on
1048 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
1049 - many small fixes and improvments in automake (mow "make dist"
1051 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
1053 shadow-20000826 => shadow-20000902
1055 This is probably the last release from me.
1056 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
1059 (I'm still interested to know what is going on with this package,
1060 which is fairly important to many Linux distributions, so please
1061 Cc: marekm@linux.org.pl in any related discussions - just don't
1062 expect me to respond quickly...)
1064 Previous warning still applies - be careful!
1066 - applied some of the Red Hat patches (revised slightly), thanks to
1067 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
1068 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
1069 in glibc 2.1.x) after changing anything, add usermod -L and -U
1070 options, remove LOG_CONS from openlog(), chage -d and -E handles
1071 dates in yyyy-mm-dd format ('/' is not required)
1074 shadow-19990827 => shadow-20000826
1076 WARNING: this release is not tested (other than that it compiles for me),
1077 please be careful. Previous release was a year ago, so it is really time
1078 to release something and start looking for a new, better maintainer...
1079 (I've been extremely busy recently. Credit for most of the real work,
1080 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1081 who maintains this package for Debian.)
1083 - merged most of the changes from Debian (not all of them yet, PAM support
1084 should be complete but is not tested - need to upgrade to potato first)
1085 - added Polish translations of manual pages from PLD
1086 - change sulog() to not depend on global variables oldname, name
1087 - try to not follow symbolic links when deleting files recursively
1088 in userdel (still not perfect, safest to do it in single user mode)

1099 it when sending to luser's tty (no need to reload with SIGHUP)
1100 - added support for "usergroups" feature often found in Linux distributions
1101 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1102 username == groupname, then set umask to 002 instead of 022)
1103 - Debian: pwck and grpck are now run from a daily cron job (root will
1104 receive an e-mail if something is wrong), and at system startup
1105 - added support for setting umask in /etc/limits
1106 - when using OPIE, re-prompt with echo on after empty password was entered
1107 - GETPASS_ASTERISKS now run time configurable (login.defs)

1110 too many characters are entered
1111 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1112 - Debian: tar wrapper no longer needed to build packages as non-root user
1113 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1114 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1115 dpkg-architecture, cross compilation, only build passwd, add
1116 etc/login.defs.hurd conffile, conditionalize CBAUD
1117 - newgrp sets $HOME before running the new shell
1118 - both "sg group command" (usage message) and "sg group -c command"
1119 (man page) work, updated both the usage message and the man page :)

1125 - fixed a bug in newgrp if the user is in >= 17 groups
1126 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1127 almost all programs need it if skey/opie support is enabled)
1128 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1129 - changed faillog to do something (assume -p) with no options specified
1130 - updated version of the udbachk passwd/shadow/group file integrity

1144 thanks to Sami Kerola
1145 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1146 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1147 - updated mailing list information (moved again, now hosted by SuSE),
1148 updated README.mirrors, other minor documentation updates
1149 - made getpass work with redirected stdin
1150 - new readpass echoing asterisks disabled by default by popular demand
1151 (can be enabled at compile time: ./configure --enable-readpass)
1152 - the random number of asterisks in readpass is now more random
1153 (random number generator initialization was missing)
1154 - commented out --enable-md5crypt (obsolete) in configure.in
1155 - when checking for libskey, link with -lcrypt if libcrypt is available
1156 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1157 - added Package/Version ident strings (so you can use the RCS "ident"
1158 command to check any binary, which version of shadow it comes from)
1160 shadow-981228 => shadow-19990307

1171 - changed to Y2K compatible version numbering
1172 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1173 values of user-entered dates (you can still enter dates in any format
1174 supported by GNU date)
1175 - oops, added doc/README.nls to list of files to distribute
1176 - added missing sanitize_env() call to src/login.c
1177 - debian/rules installs /bin/login non-setuid by default, just in case...
1178 - build Debian packages with cracklib support (depends on cracklib-runtime)
1180 shadow-980724 => shadow-981228

1197 shadow-980626 => shadow-980724

1201 by Ted Hickman <thickman@sy.net>
1202 - remove libshadow.so -> libshadow.so.x.x symlink after install
1203 - a few int -> uid_t type cleanups
1204 - fail immediately (don't retry) in *_lock() if euid != 0
1205 - added sample PAM config files etc/pam.d/{passwd,su}

1225 shadow-980417 => shadow-980529
1227 - fixed "interesting" strzero() bug introduced by me in 980417:
1228 strzero(cp) didn't work as intended (the macro used a local
1229 variable called "cp" - oops...); Leonard N. Zubkoff was the
1230 first person to report it - thanks!
1231 - fixed usermod -e to accept empty argument (like useradd),
1232 thanks to Martin Bene

1250 - security: su now creates the sulog file (if enabled and doesn't
1251 already exist) with umask 077
1252 - hopefully removed arbitrary group size limits (not yet for
1253 shadow groups though - sgetsgent() still needs a rewrite,
1254 but I don't want to delay this release any longer...)
1255 - fixed NULL dereference in groupmod -n
1257 shadow-971215 => shadow-980130
1259 - Debian binary packages can be built without root privileges

1261 - new subdir "redhat" (needs more work, see redhat/README)
1262 - in several places, exit(127) if exec fails with ENOENT, and
1263 exit(126) on other errors (as in ksh and bash)
1264 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1265 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1266 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1267 - handle crypt() returning NULL (possible according to Single Unix
1268 Spec) more gracefully (exit instead of SIGSEGV)

1280 (so I don't have to edit version numbers for every new release)
1281 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1282 ("force" - exit(0) if the group already exists); other RedHat-
1283 specific options not added yet (best done in a perl script that
1284 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1285 - added -O option (override login.defs values) to useradd and groupadd
1286 - if usermod can't update the group file(s), exit(10) but update the
1287 password file(s) anyway (as documented by Solaris man page)
1288 - useradd should no longer set sp_expire to the current date (oops)
1289 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1290 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1291 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1292 detection, setpgrp vs. setpgid, other minor tweaks
1293 - various */Makefile.am tweaks
1294 - login.defs: added FAKE_SHELL - program to run instead of the login
1295 shell, with the real shell in argv[0] (Frank Denis)
1296 - login.defs: ignore case in yes/no settings
1297 - more E_* defines instead of hardcoded numbers for exit()
1298 - added sanitize_env() for setuid programs
1299 - login_desrpc() checks for getnetname() errors
1300 - new password is not "too similar" if it is long enough
1301 - replacement strstr() was static, no one noticed :-)
1302 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1303 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1304 - login sets $REMOTEHOST for remote logins
1305 - added newgrp -l option (Single Unix Spec, same as "-")
1306 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1307 200K of disk space on Linux/x86), enabled by default if supported by
1308 the system, use ./configure --disable-shared if it causes any problems.
1309 Warning: libshadow.so is intended for internal use by this package
1310 only - binary compatibility with future releases is not guaranteed.
1311 There should be no need to link any other programs with libshadow.so -
1312 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1313 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1314 version (!) - added check to configure; fixed do_pam_passwd prototype
1315 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1316 - added information about the new ftp site to doc/README.mirrors
1318 shadow-971001 => shadow-971215
1320 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1321 - updated the RPM .spec file
1322 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1323 (glibc defines something else named "rlogin" in utmpbits.h ?)
1324 - added MD5 checksums in Debian packages
1325 - added -p and -g options to vipw (edit the password or group file
1326 respectively, regardless of the command name in argv[0])
1327 - removed old DBM support (NDBM code is still there)
1328 - fixed a bug in gpasswd: current username was incorrectly identified as
1329 "root" because of setuid(0) done too early. It may be a security hole
1330 when using shadow groups - if "root" is listed as a group administrator,
1331 any user can add/remove members in that group. Thanks to Jesse Thilo.
1332 - gpasswd now logs which user (root or group admin) made the changes
1333 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1334 - newgrp and add_groups() allocate supplementary group lists dynamically
1335 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1336 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1337 changed by regular users (any combination of letters "frwh")
1338 - fixed contrib/pwdauth.c segfault with non-existent usernames
1339 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1340 - new date parsing code (from GNU date) used by useradd, usermod, chage
1341 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1342 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1343 - fixed useradd -G segfault (one '*' that shouldn't be there)
1344 - allow 8-bit characters in chfn
1345 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1346 - changed the handling of NIS plus entries in password files
1347 - some more tweaking in various debian/* files
1348 - logoutd uses getutent() instead of reading utmp file directly
1349 - fixed lckpwdf() called twice (and failing) when changing password
1350 if the user is not listed in /etc/shadow (Mike Pakovic)
1351 - erase and kill characters left unchanged if not defined in login.defs
1353 shadow-970616 => shadow-971001
1355 - Debian: mkpasswd no longer installed (dbm files not supported)
1356 - chpasswd checks for shadow/non-shadow at run time, too
1357 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1358 - changed libmisc/login_access.c as suggested by Dave Hagewood
1359 - replaced sprintf() with snprintf() in several places
1360 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1361 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1362 - non-root users can only run su with a terminal on stdin
1363 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1364 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1365 in libc, or system misconfiguration. Needs further investigation.
1366 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1367 - fixed free() called twice in libmisc/mail.c
1368 - added information about mirror sites (doc/README.mirrors)
1369 - updated pwconv.8 and pwunconv.8 man pages
1370 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1371 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1372 - corrected su.1 man page ($SHELL not used)
1373 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1374 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1375 - cleaned up PASS_MAX in getpass() (127 always assumed)
1376 - default editor for vipw changed from /bin/ae to a real editor :)
1378 shadow-970601 => shadow-970616
1380 - fixed execlp call (missing NULL) in src/vipw.c
1381 - vipw now preserves permissions on edited files
1382 - commented out the xdm-shadow hack in shadowconfig
1383 - improved RedHat spec file (Timo Karjalainen)
1384 - updated mailing list information
1385 - added information about the shadow paper (doc/README.shadow-paper)
1386 - renamed doc/console.c.spec (confused RPM)
1388 shadow-970502-2 => shadow-970601
1390 - fixed a typo in libmisc/mail.c causing login to segfault
1391 if MAIL_CHECK_ENAB=yes (sorry!)
1392 - patches for OPIE support (Algis Rudys) (untested)
1393 - programs that modify /etc/passwd or /etc/shadow will use
1394 lckpwdf() if available
1395 - now compiles with PAM support! (still untested)
1396 - cosmetic error message changes (prefixed by argv[0]:)
1398 shadow-970216 => shadow-970502-2
1400 - shadow group support fixes (grpconv didn't work - for some
1401 reason, putsgent() returns 1 instead of 0 on success;
1402 now -1 = failure, anything else = success)
1403 - upgraded to autoconf-2.12
1404 - pwconv and pwunconv now follow other UN*X systems and SVID3
1405 (modify files in place), original versions moved to "old"
1406 - scologin.c moved to "old" (it was only for SCO Xenix) so
1407 people stop sending patches for scologin.c gcc warnings :)
1408 - don't use the MD5* functions in libmisc/salt.c (glibc has
1409 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1410 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1411 - "passwd -S -a" now really works
1412 - support for Debian, vipw, a few fixes (Guy Maor)
1413 - src/login.c radius bug fix (Rafal Maszkowski)
1414 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1415 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1416 - limits.5 man page (Luca Berra)
1417 - expiry will work setgid shadow too, removed euid 0 check
1418 - added check for a64l() to configure (glibc)
1420 shadow-961025 => shadow-970216
1422 - major rewrite of *io.c (no more 4 copies of almost identical code)
1423 - use fsync() (if available) instead of sync() when updating password files
1424 - use fchmod() and fchown() if available
1425 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1426 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1427 - passwd -S -a: list information about all users (root only)
1428 - passwd -k: change only expired passwords
1429 - passwd -q: quiet mode
1430 - first attempt at PAM support in passwd
1431 - passwd updates the non-shadow password if /etc/shadow exists but the
1432 user has no shadow password
1433 - passwd logs who changed the password, added hook to allow non-root
1434 administrators who can change passwords (not implemented yet)
1435 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1436 - added -p (set encrypted password) option to useradd and usermod
1437 (idea from hpux10 - undocumented option used internally by SAM)
1438 - useradd -D -e does the right thing (set default expiration date)
1439 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1440 because there are just too many systems that need different commands
1441 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1442 faillog file format has been changed (somewhere between 960129 and
1443 960810), please truncate the old file (if any) to zero length
1444 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1445 - wtmp, lastlog, faillog file location guessed by configure
1446 - separate checks for invalid user and group names, max username length
1447 based on struct utmp (it's not always 8 characters)
1448 - pwck and grpck now check for invalid user/group names
1449 - pwck -q (quiet, report only serious problems) option added
1450 - separate cleaner sgetpwent() without the NIS magic
1451 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1452 - various code cleanups
1453 - new get_my_pwent() function for getting my own username, uid etc.
1454 - faillog opens the file read-write if possible (even if not root)
1455 - passwd -S allowed for normal users (for their own uid only)
1456 - handle the case of login denied to passwordless accounts better
1457 ("Login incorrect" without "Password:" prompt looks strange)
1458 - corrected author information and removed a copyright restriction
1460 shadow-960925 => shadow-961025
1462 - fixed a few typos in shadow group code
1463 - don't check for names starting with 'r' to determine if the shell
1464 is restricted, use /etc/shells instead (for the "rc" shell)
1465 - removed extra definition of LASTLOG_FILE in configure.in
1466 - expiry no longer segfaults if no /etc/shadow
1467 - userdel -r "can't remove mailbox" warning no longer printed on success
1468 - useradd exit codes changed to match hpux10 man page
1469 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1471 shadow-960920 => shadow-960925
1473 - bug fixes to the new environment code using malloc
1474 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1475 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1476 - small fix to isexpired(), and use it in passwd as well
1477 - use strftime() and strptime() if available
1478 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1479 contain encrypted passwords!)
1480 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1481 (nothing bad happened yet, just a cleanup)
1482 - gpasswd should work with both shadow and non-shadow group passwords
1483 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1484 - passwd -e for sunos4 (ATT_AGE), untested
1485 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1486 - small fix to l64a()
1487 - passwd prints a message after password successfully changed (for things
1488 like poppassd which run passwd and expect some output)
1489 - passwd logs if password was changed by root (as opposed to a luser)
1490 - passwd uses current uid if no username argument and getlogin() fails
1492 shadow-960910 => shadow-960920
1494 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1495 - newusers should work with both shadow and non-shadow passwords
1496 (still left to do: chpasswd, gpasswd)
1497 - login-static no longer compiled by default
1498 - more SYSLOG() macros
1500 shadow-960810 => shadow-960910
1502 - updated README.linux to point to the new ftp site
1503 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1504 - man pages now closer to LDP standards (Ivan Nejgebauer)
1505 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1506 - obscure.c fixed to compile with HAVE_LIBCRACK
1507 - cosmetic message changes in age.c
1508 - utmp open error check fixed in utmp.c
1509 - grpunconv added (Michael Meskes)
1510 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1511 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1512 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1513 - passwords can be changed if sp_max == -1 (now considered infinity)
1514 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1515 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1516 - contrib/rpasswd.c added (Joshua Cowan)
1517 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1518 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1519 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1521 shadow-960129 => shadow-960810
1523 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1524 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1525 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1526 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1527 - hopefully removed all the rcsid warnings
1528 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1529 - resource limits (Cristian Gafton)
1530 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1531 - more fixes in man pages
1532 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1533 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1534 su, useradd, userdel, usermod) should now work with both shadow and
1535 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1536 run time); a few programs still left to do
1537 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1538 - new contrib/adduser.c from Chris Evans
1539 - lots of other minor changes
1540 - source tree reorganization, GNU autoconf, portability cleanups
1541 - basename() renamed to Basename() to avoid name space confusion
1542 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1543 - newgrp cleanup and a few fixes
1544 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1545 - don't make the first group member the group admin by default
1546 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1547 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1548 place (defines.h) instead of repeating it in all source files...
1549 - added userdel -r safety check (refuse to remove the home directory
1550 if it would result in removing some other user's home directory)
1551 - usermod -u now correctly checks for non-unique uid (unless -o)
1552 - sync() after updating password files, just to be more safe
1553 - "make install" should install /etc/login.defs if it doesn't exist
1554 - new option to control what happens if we can't cd to the home directory
1555 (DEFAULT_HOME in /etc/login.defs)
1556 - enter the home directory as the user, not as root (for NFS etc.)
1557 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1558 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1559 possible to add specified groups (floppy etc.) for console logins
1560 - new faillog feature: lock account for specified (per-user) time since
1561 the last failure after exceeding the failure limit
1562 - new man pages (gpasswd.1, login.access.5, suauth.5)
1563 - fixes in man pages, renamed *.4 to *.5
1564 - new "contrib" directory (two adduser programs)
1565 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1566 - sulogin no longer requires to be run from init, should work from rc
1568 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1569 using xx_locate(), modify it and call xx_update(), don't write back
1570 anything returned by getpwnam() etc.)
1571 - stupid bug fixed in lastlog.c
1572 - don't move non-directories in "usermod -m"
1573 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1574 - macros to get around ancient compilers which don't like prototypes
1575 - make more use of "const" (not everywhere yet)
1576 - added #ifdef AUTH_METHODS - very few people use administrator defined
1577 authentication methods because many programs are not aware of them;
1578 not supporting them makes the code simpler
1579 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1580 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1581 see HAVE_SGETGRENT in config.h (grent.c)
1582 - don't use continued lines in /etc/group, the standard getgr*() functions
1583 don't support that (grent.c)
1584 - removed the third main() argument (according to libc docs, not allowed by
1585 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1586 - login access control (lmain.c, login_access.c)
1587 - added copyright notice to login_access.c (from logdaemon-5.0)
1588 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1589 - added closelog() in su before executing the shell (smain.c)
1590 - getting current user name changed (smain.c)
1591 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1592 - getpass() shouldn't return NULL except on errors (getpass.c)
1593 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1594 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1595 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1596 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1597 - "no shadow password" not logged, the same /bin/login should work with both
1598 shadow and non-shadow passwords (lmain.c)
1599 - some cleanup in various places (lmain.c, passwd.c)
1600 - new program to verify username/password pairs, for xlock etc.; it is not
1601 installed by default, read the comments first (pwdauth.c)
1602 - authentication programs run with empty environment for safety (pwauth.c)
1603 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1604 - common code separated from *io.c (commonio.c)
1605 - ownership and permissions on password files are now preserved (we may try
1606 to make more use of setgid and setuid non-root programs in the future)
1607 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1608 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
1609 - termios/termio/sgtty macros cleaned up a bit
1611 shadow-951218 => shadow-960129
1613 Emergency bug fix release - no new features since 951218. There are many
1614 new changes, but this bug really can't wait until they are tested.
1616 Probably all previous versions of the shadow suite have a serious bug which
1617 makes it possible to overwrite the stack by entering very long username at
1618 the login prompt. This can give root access to any remote user!
1620 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
1621 size of the array in lmain.c). Aaargh!!!
1623 shadow-951203 => shadow-951218
1626 - Linux utmp handling fixes (utmp.c)
1627 - last failure date printing fixes (failure.c)
1628 - minor fix to compile with USE_CRACKLIB (obscure.c)
1629 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
1630 - basename.c added, replacing duplicated code in various places
1631 - "su -" runs the shell with '-' in argv[0] again (smain.c)
1632 - removing at/cron jobs cleaned up (userdel.c)
1633 - /etc/gshadow should not be world-readable (sgroupio.c)
1634 - if fflush() failed, files were not closed (*io.c)
1635 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
1636 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
1637 - some minor cleanups for gcc -Wall (unused variables etc.)
1638 - removed README.FIRST (copyrights are OK now)
1639 - updated ANNOUNCE, README.linux, WISHLIST
1640 - as suggested, converted to RCS
1642 shadow-3.3.2-951127 => shadow-951203-jfh
1645 - Added the BSD-style copyright to all of the files. Any files with the
1646 old copyright have multiple copyright holders and need to be cleanroomed
1647 to produce BSD-style copyrightable files, or I need to get the consent
1648 of the others to change the copyright.
1649 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
1650 that all of the files should have the correct copyright there is no need
1651 to refer to that e-mail message.
1652 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
1653 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
1655 jfh@rpp386.cactus.org
1657 shadow-3.3.2-951106 => shadow-951127
1659 Note: for now this code only supports Linux. All the #ifdef's are there
1660 (and will be; support for at least SunOS 4.1.x would be nice) but:
1661 - I had to fix some potential security problems resulting from sloppy
1662 coding (no bounds checking), and it was easier for me to use snprintf()
1663 (not available on many systems, unfortunately), I'll fix that later.
1664 Old versions of Linux libc don't have snprintf() either, and the one
1665 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
1666 - I am lazy and only updated Makefile.linux and config.h.linux this time
1667 - I don't have root access to non-Linux systems (this means no testing)
1668 - this code needs some major reorganization, which will (hopefully)
1672 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
1673 - login can be statically linked (not that I think it's a good idea, better
1674 fix the telnetd, but paranoid people will like it :-)
1675 - login is installed non-setuid by default
1676 - check for NULL from getpass()
1677 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
1678 - use standard "Password: " prompt by default (pwauth.c)
1679 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
1680 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
1681 - Linux has <lastlog.h>
1682 - print ll_host on Linux too (lmain.c)
1683 - size checking in various places (setuid root programs, argh!)
1684 - preserve TERM from getty (lmain.c)
1685 - don't ignore SIGHUP (lmain.c)
1686 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
1687 - remove LD_xxx (env.c)
1688 - use bzero() instead of memset() for BSD portability and less #ifdef's
1689 (if the system has no bzero(), implement it as a macro using memset())
1690 - the above fixes wrong order of memset() parameters (log.c)
1691 - use getutent/pututline instead of doing it by hand (utmp.c)
1692 - added the new settings to login.defs.linux
1693 - added login_access.c to the distribution (not used yet)
1697 shadow-3.3.2 => shadow-3.3.2-951106
1699 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
1700 - malloc/strdup error checking, hopefully no more core dumps...
1701 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
1702 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
1703 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
1704 - use POSIX termios whenever possible on Linux
1705 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
1706 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
1707 - login -h only for root (lmain.c)
1708 - login -r not needed for Linux (lmain.c)
1709 - sample login.defs modified for Linux (login.defs.linux)
1710 - swapped chfn USAGE and ADMUSAGE (chfn.c)
1711 - added -u to passwd usage (passwd.c)
1712 - no #! check necessary for Linux (shell.c)
1713 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
1714 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
1715 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
1716 can now be set in login.defs, old values are used as defaults (lmain.c)
1717 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
1718 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
1719 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
1720 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
1721 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
1722 - check for weak passwords too if previous password was empty (obscure.c)
1723 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
1724 - Linux has getusershell(), use it (chsh.c)
1725 - check if the new shell is executable by the user (chsh.c)
1726 - sleep before printing "Login incorrect", not the other way around (lmain.c)
1727 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
1728 - do "wheel group" more like BSD does (smain.c)
1729 - use getlogin() in su (smain.c)
1730 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
1731 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
1732 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
1733 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
1734 - LOGIN_STRING should work now (pwauth.c, getdef.c)
1735 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
1736 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
1737 not lost when you copy the right ones to Makefile and config.h
