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

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

286 - userdel, usermod: fixed segfault on remove home directory when it can't
287 be removed; for example when it is /dev/null (fixed http://bugs.gentoo.org/139148),
288 - improved SELinux detection on autoconf level (based on patch by
289 Dan Yefimov <dan@D00M.lightwave.net.ru>),
290 - removed using private implementation getpass() libc function
291 (now getpass() is used also when S/KEY support is enabled),

311 proceeding with the fchmod() (based on Owl patch prepared by
312 Rafal Wojtczuk <nergal@owl.openwall.com>),
313 - userdel: use login.defs::MAIL_DIR instead hardcoded /var/mail in created
314 mailbox path (based on Owl fixes submited
315 by Solar Designer <solar@openwall.com>),
316 - by default do not use libshadow_getpass() as getpass() replacemement.
317 Use libshadow_getpass() only when S/KEY support is enabled.
318 Current glibc getpass() handles correctly longer than 8 characters
319 passwords and libshadow_getpass() is used only because libc getpass()
320 do not handles password prompting with echo enabled,
321 - move login.defs::MD5_CRYPT_ENAB to non-PAM part,
322 - userdel: rewrited for use getopt_log(),
323 - install default/template configuration files:
324 -- if shadow is configured with use PAM install /etc/pam.d/* files,
325 -- if shadow do not uses PAM install /etc/{limits,login.acces} files,
326 -- install /etc/login.defs and /etc/default/useradd files,
327 - fixed handle relative symlinks too in lib/commonio.c
328 (merge patch from Fedora),
329 - properly notify nscd to flush its cache
330 (https://bugzilla.redhat.com/bugzilla/186803),

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

381 Peter Vrabec <pvrabec@redhat.com>),
382 - chgpasswd: new tool (by Jonas Meurer <mejo@debian.org>),
383 - lastlog: print the usage and exit if an additional argument is profided to
384 lastlog (merge 488_laslog_verify_arguments Debian patch),
385 - login, newgrp, nologin, su: do not link with libselinux (merge
386 490_link_selinux_only_when_needed Debian patch),

388 mounted (http://bugs.debian.org/352494 patch Nicolas François
389 <nicolas.francois@centraliens.net>),
390 - login (merge 433_login_more_LOG_UNKFAIL_ENAB Debian patch):

398 - changed pam_end to PAM_END. This is certainly was a mistake. PAM_END is
399 pam_close_seesion + pam_end. Here, the session is still not open, we
400 don't have to close it.
401 - a HAVE_PAM_FAIL_DELAY is missing,
402 - su: fixed pam session support (patch from Topi Miettinen; fixed #57526,
403 #55873, 57532 Debian bugs),

420 on higher level (now is better visable where some programs exit with 126
421 and 127 exit codes); added new shell() parameter (char *const envp[])
422 which allow fix preserving enviloment in su on using -p, (patch by
423 Alexander Gattin <xrgtn@yandex.ru>),

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

463 - userdel: fix incorrect audit record in userdel
464 (https://bugzilla.redhat.com/bugzilla/174392),
465 - userdel: remove the user's group unless it is not really a user-private group
466 for better PUG support (based on FC patch),
467 - userdel: make the -f option force the removal of the user's group (even if it
468 is the primary group of another user)
469 (merge 453_userdel_-f_removes_group Debian patch),
470 - usermod: rewrited for use getopt_long() (Christian Perrier <bubulle@kheops.frmug.org>),
471 - grpck: fixed segmentation fault on using -s when /etc/gshadow is empty (fix by
472 Tomasz Lemiech <szpajder@staszic.waw.pl>),
473 - passwd: remove handle -f, -g and -s options.
474 - added handle -s/--shell, -m/-p/preserve-environment options like GNU su

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

853 shadow-4.0.4.1-owl-tmp.diff:
854 Remove using mktemp() if mkstemp() prototype not found (use allways mkstemp()),
855 shadow-4.0.4.1-owl-check-reads.diff:

956 shadow-4.0.0-owl-chage-ro-no-lock.diff:
957 Added locks which are needed when doing r/w accesses, not when running
958 as root. If root does read-only, there's no lock needed. Added missing
959 "#include <errno.h>" for above (me).
960 shadow-4.0.0-owl-warnings.diff
961 Olny one fix from this patch was aplayd because other was fixed few days
963 shadow-4.0.0-owl-check_names.diff
964 Merge only prat this patch with checking login name matching; checking
965 is login string isn't longer than possible it will be good prepare using
966 probably _POSIX_LOGIN_NAME_MAX from <bits/posix1_lim.h>,
967 shadow-4.0.0-owl-chage-drop-priv.diff
968 shadow-4.0.0-owl-pam-auth.diff
969 Merge part with reorder initialize PAM and checkin is chage is runed by

984 shadow-20001016 => shadow-4.0.0 06-01-2002
986 - fix bug discovered and fixed by Marcel Ritter
987 <Marcel.Ritter@rrze.uni-erlangen.de>
988 Due to a big buffer size in lib/commonio.c this error does only appear
989 if a line gets longer than 4096 bytes (there are probably very few people
990 stumbling across this).
991 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
996 while [ $NUM -le 1000 ]; do
997 useradd -g demogroup -G demogroup -p "NONE" user$NUM
1000 - remove limit 32 to groups per user by (the same user can belong to
1001 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
1002 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
1003 NOTE: it probably need testing on other system for add
1004 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
1005 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
1006 - drop detecting is pam_strerror() need one or two arguments. Instead using
1007 PAM_STRERROR() macro use directly pam_strerror() function with two
1008 arguments. pam_strerror() with one argument is obsoleted,
1009 - adde ja man pages (probably some man pages need update),
1010 - much better automake support,
1011 - added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
1012 groupmod(8), shadow(5) (man pages for other nations also are welcome),
1013 - mamny small fixes and updates nad improvements in man pages,
1014 - aplayed Debian patch to man pages for shadowconfig,
1015 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
1018 shadow-20001012 -> shadow-20001016:
1019 - conditionaly disabled body reload_nscd() because not every
1020 version of nscd can handle it (this can be enabled by define
1021 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
1022 - fixes on autoconf/automake level for dist target,
1023 - Julianne F. Haugh new contact adress.
1025 shadow-20000902 => shadow-20001012
1027 - removed /redhat directory with obsoleted files (partialy rewrited spec
1028 file is now in root directory),
1029 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
1030 overwrite previously existing groups in adduser,
1031 - added PAM support for chage (bind to "chage" PAM config file) also
1032 added PAM support for all other small tools like chpasswd, groupadd,
1033 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
1034 "shadow" PAM config file) - this modificaytions mainly based on
1035 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
1036 - many small fixes and improvments in automake (mow "make dist"
1038 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
1040 shadow-20000826 => shadow-20000902
1042 This is probably the last release from me.
1043 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
1046 (I'm still interested to know what is going on with this package,
1047 which is fairly important to many Linux distributions, so please
1048 Cc: marekm@linux.org.pl in any related discussions - just don't
1049 expect me to respond quickly...)
1051 Previous warning still applies - be careful!
1053 - applied some of the Red Hat patches (revised slightly), thanks to
1054 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
1055 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
1056 in glibc 2.1.x) after changing anything, add usermod -L and -U
1057 options, remove LOG_CONS from openlog(), chage -d and -E handles
1058 dates in yyyy-mm-dd format ('/' is not required)
1061 shadow-19990827 => shadow-20000826
1063 WARNING: this release is not tested (other than that it compiles for me),
1064 please be careful. Previous release was a year ago, so it is really time
1065 to release something and start looking for a new, better maintainer...
1066 (I've been extremely busy recently. Credit for most of the real work,
1067 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1068 who maintains this package for Debian.)
1070 - merged most of the changes from Debian (not all of them yet, PAM support
1071 should be complete but is not tested - need to upgrade to potato first)
1072 - added Polish translations of manual pages from PLD
1073 - change sulog() to not depend on global variables oldname, name
1074 - try to not follow symbolic links when deleting files recursively
1075 in userdel (still not perfect, safest to do it in single user mode)
1076 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
1077 (a few ANSI C constructs were used already, and no one complained)
1078 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
1080 shadow-19990709 => shadow-19990827

1086 it when sending to luser's tty (no need to reload with SIGHUP)
1087 - added support for "usergroups" feature often found in Linux distributions
1088 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1089 username == groupname, then set umask to 002 instead of 022)
1090 - Debian: pwck and grpck are now run from a daily cron job (root will
1091 receive an e-mail if something is wrong), and at system startup
1092 - added support for setting umask in /etc/limits
1093 - when using OPIE, re-prompt with echo on after empty password was entered
1094 - GETPASS_ASTERISKS now run time configurable (login.defs)

1097 too many characters are entered
1098 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1099 - Debian: tar wrapper no longer needed to build packages as non-root user
1100 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1101 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1102 dpkg-architecture, cross compilation, only build passwd, add
1103 etc/login.defs.hurd conffile, conditionalize CBAUD
1104 - newgrp sets $HOME before running the new shell
1105 - both "sg group command" (usage message) and "sg group -c command"
1106 (man page) work, updated both the usage message and the man page :)
1107 - i18n: added missing _() for some translatable strings
1109 shadow-19990607 => shadow-19990709
1111 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
1112 - fixed a bug in newgrp if the user is in >= 17 groups
1113 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1114 almost all programs need it if skey/opie support is enabled)
1115 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1116 - changed faillog to do something (assume -p) with no options specified
1117 - updated version of the udbachk passwd/shadow/group file integrity

1127 - started adding PAM support to login (based on util-linux, not finished yet)
1128 - changed "!" to "x" for pw_passwd in src/newusers.c
1129 - a few more Y2K fixes
1130 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
1131 thanks to Sami Kerola
1132 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1133 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1134 - updated mailing list information (moved again, now hosted by SuSE),
1135 updated README.mirrors, other minor documentation updates
1136 - made getpass work with redirected stdin
1137 - new readpass echoing asterisks disabled by default by popular demand
1138 (can be enabled at compile time: ./configure --enable-readpass)
1139 - the random number of asterisks in readpass is now more random
1140 (random number generator initialization was missing)
1141 - commented out --enable-md5crypt (obsolete) in configure.in
1142 - when checking for libskey, link with -lcrypt if libcrypt is available
1143 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1144 - added Package/Version ident strings (so you can use the RCS "ident"
1145 command to check any binary, which version of shadow it comes from)
1147 shadow-981228 => shadow-19990307

1157 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1158 - changed to Y2K compatible version numbering
1159 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1160 values of user-entered dates (you can still enter dates in any format
1161 supported by GNU date)
1162 - oops, added doc/README.nls to list of files to distribute
1163 - added missing sanitize_env() call to src/login.c
1164 - debian/rules installs /bin/login non-setuid by default, just in case...
1165 - build Debian packages with cracklib support (depends on cracklib-runtime)
1167 shadow-980724 => shadow-981228
1169 - login now clears the username in argv[] (in case someone types the
1170 password instead of username, by mistake)

1184 shadow-980626 => shadow-980724
1186 - security: login no longer gives you a root shell if setgid()
1187 or initgroups() or setuid() fails for any reason, discovered
1188 by Ted Hickman <thickman@sy.net>
1189 - remove libshadow.so -> libshadow.so.x.x symlink after install
1190 - a few int -> uid_t type cleanups
1191 - fail immediately (don't retry) in *_lock() if euid != 0
1192 - added sample PAM config files etc/pam.d/{passwd,su}
1193 - preliminary PAM support in su (untested - use at your own risk,
1194 comments and patches welcome!)
1195 - cleanup and more comments in OPIE code (Algis Rudys)
1196 - added support for TCFS (Transparent Cryptographic File System)
1197 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/

1210 - pwconv.8: documented that it may fail on invalid password files
1212 shadow-980417 => shadow-980529
1214 - fixed "interesting" strzero() bug introduced by me in 980417:
1215 strzero(cp) didn't work as intended (the macro used a local
1216 variable called "cp" - oops...); Leonard N. Zubkoff was the
1217 first person to report it - thanks!
1218 - fixed usermod -e to accept empty argument (like useradd),
1219 thanks to Martin Bene
1220 - several changes from Debian 980403-0.2, see debian/changelog

1232 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1235 shadow-980130 => shadow-980403
1237 - security: su now creates the sulog file (if enabled and doesn't
1238 already exist) with umask 077
1239 - hopefully removed arbitrary group size limits (not yet for
1240 shadow groups though - sgetsgent() still needs a rewrite,
1241 but I don't want to delay this release any longer...)
1242 - fixed NULL dereference in groupmod -n
1244 shadow-971215 => shadow-980130
1246 - Debian binary packages can be built without root privileges
1247 (tar wrapper - debian/tar.c)
1248 - new subdir "redhat" (needs more work, see redhat/README)
1249 - in several places, exit(127) if exec fails with ENOENT, and
1250 exit(126) on other errors (as in ksh and bash)
1251 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1252 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1253 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1254 - handle crypt() returning NULL (possible according to Single Unix
1255 Spec) more gracefully (exit instead of SIGSEGV)
1256 - fixed bug in putgrent() that showed up when realloc() moved the
1257 buffer while expanding it, thanks to Floody <flood@evcom.net>

1259 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1260 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1261 - newer config.guess and config.sub (should work on x86 for x > 5)
1262 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1263 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1264 - documented more (not all yet) login.defs(5) settings
1265 - replaced more exit status numeric values with #defines
1266 - shadow-utils.spec now generated from shadow-utils.spec.in
1267 (so I don't have to edit version numbers for every new release)
1268 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1269 ("force" - exit(0) if the group already exists); other RedHat-
1270 specific options not added yet (best done in a perl script that
1271 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1272 - added -O option (override login.defs values) to useradd and groupadd
1273 - if usermod can't update the group file(s), exit(10) but update the
1274 password file(s) anyway (as documented by Solaris man page)
1275 - useradd should no longer set sp_expire to the current date (oops)
1276 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1277 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1278 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1279 detection, setpgrp vs. setpgid, other minor tweaks
1280 - various */Makefile.am tweaks
1281 - login.defs: added FAKE_SHELL - program to run instead of the login
1282 shell, with the real shell in argv[0] (Frank Denis)
1283 - login.defs: ignore case in yes/no settings
1284 - more E_* defines instead of hardcoded numbers for exit()
1285 - added sanitize_env() for setuid programs
1286 - login_desrpc() checks for getnetname() errors
1287 - new password is not "too similar" if it is long enough
1288 - replacement strstr() was static, no one noticed :-)
1289 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1290 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1291 - login sets $REMOTEHOST for remote logins
1292 - added newgrp -l option (Single Unix Spec, same as "-")
1293 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1294 200K of disk space on Linux/x86), enabled by default if supported by
1295 the system, use ./configure --disable-shared if it causes any problems.
1296 Warning: libshadow.so is intended for internal use by this package
1297 only - binary compatibility with future releases is not guaranteed.
1298 There should be no need to link any other programs with libshadow.so -
1299 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1300 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1301 version (!) - added check to configure; fixed do_pam_passwd prototype
1302 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1303 - added information about the new ftp site to doc/README.mirrors
1305 shadow-971001 => shadow-971215
1307 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1308 - updated the RPM .spec file
1309 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1310 (glibc defines something else named "rlogin" in utmpbits.h ?)
1311 - added MD5 checksums in Debian packages
1312 - added -p and -g options to vipw (edit the password or group file
1313 respectively, regardless of the command name in argv[0])
1314 - removed old DBM support (NDBM code is still there)
1315 - fixed a bug in gpasswd: current username was incorrectly identified as
1316 "root" because of setuid(0) done too early. It may be a security hole
1317 when using shadow groups - if "root" is listed as a group administrator,
1318 any user can add/remove members in that group. Thanks to Jesse Thilo.
1319 - gpasswd now logs which user (root or group admin) made the changes
1320 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1321 - newgrp and add_groups() allocate supplementary group lists dynamically
1322 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1323 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1324 changed by regular users (any combination of letters "frwh")
1325 - fixed contrib/pwdauth.c segfault with non-existent usernames
1326 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1327 - new date parsing code (from GNU date) used by useradd, usermod, chage
1328 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1329 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1330 - fixed useradd -G segfault (one '*' that shouldn't be there)
1331 - allow 8-bit characters in chfn
1332 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1333 - changed the handling of NIS plus entries in password files
1334 - some more tweaking in various debian/* files
1335 - logoutd uses getutent() instead of reading utmp file directly
1336 - fixed lckpwdf() called twice (and failing) when changing password
1337 if the user is not listed in /etc/shadow (Mike Pakovic)
1338 - erase and kill characters left unchanged if not defined in login.defs
1340 shadow-970616 => shadow-971001
1342 - Debian: mkpasswd no longer installed (dbm files not supported)
1343 - chpasswd checks for shadow/non-shadow at run time, too
1344 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1345 - changed libmisc/login_access.c as suggested by Dave Hagewood
1346 - replaced sprintf() with snprintf() in several places
1347 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1348 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1349 - non-root users can only run su with a terminal on stdin
1350 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1351 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1352 in libc, or system misconfiguration. Needs further investigation.
1353 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1354 - fixed free() called twice in libmisc/mail.c
1355 - added information about mirror sites (doc/README.mirrors)
1356 - updated pwconv.8 and pwunconv.8 man pages
1357 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1358 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1359 - corrected su.1 man page ($SHELL not used)
1360 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1361 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1362 - cleaned up PASS_MAX in getpass() (127 always assumed)
1363 - default editor for vipw changed from /bin/ae to a real editor :)
1365 shadow-970601 => shadow-970616
1367 - fixed execlp call (missing NULL) in src/vipw.c
1368 - vipw now preserves permissions on edited files
1369 - commented out the xdm-shadow hack in shadowconfig
1370 - improved RedHat spec file (Timo Karjalainen)
1371 - updated mailing list information
1372 - added information about the shadow paper (doc/README.shadow-paper)
1373 - renamed doc/console.c.spec (confused RPM)
1375 shadow-970502-2 => shadow-970601
1377 - fixed a typo in libmisc/mail.c causing login to segfault
1378 if MAIL_CHECK_ENAB=yes (sorry!)
1379 - patches for OPIE support (Algis Rudys) (untested)
1380 - programs that modify /etc/passwd or /etc/shadow will use
1381 lckpwdf() if available
1382 - now compiles with PAM support! (still untested)
1383 - cosmetic error message changes (prefixed by argv[0]:)
1385 shadow-970216 => shadow-970502-2
1387 - shadow group support fixes (grpconv didn't work - for some
1388 reason, putsgent() returns 1 instead of 0 on success;
1389 now -1 = failure, anything else = success)
1390 - upgraded to autoconf-2.12
1391 - pwconv and pwunconv now follow other UN*X systems and SVID3
1392 (modify files in place), original versions moved to "old"
1393 - scologin.c moved to "old" (it was only for SCO Xenix) so
1394 people stop sending patches for scologin.c gcc warnings :)
1395 - don't use the MD5* functions in libmisc/salt.c (glibc has
1396 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1397 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1398 - "passwd -S -a" now really works
1399 - support for Debian, vipw, a few fixes (Guy Maor)
1400 - src/login.c radius bug fix (Rafal Maszkowski)
1401 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1402 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1403 - limits.5 man page (Luca Berra)
1404 - expiry will work setgid shadow too, removed euid 0 check
1405 - added check for a64l() to configure (glibc)
1407 shadow-961025 => shadow-970216
1409 - major rewrite of *io.c (no more 4 copies of almost identical code)
1410 - use fsync() (if available) instead of sync() when updating password files
1411 - use fchmod() and fchown() if available
1412 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1413 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1414 - passwd -S -a: list information about all users (root only)
1415 - passwd -k: change only expired passwords
1416 - passwd -q: quiet mode
1417 - first attempt at PAM support in passwd
1418 - passwd updates the non-shadow password if /etc/shadow exists but the
1419 user has no shadow password
1420 - passwd logs who changed the password, added hook to allow non-root
1421 administrators who can change passwords (not implemented yet)
1422 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1423 - added -p (set encrypted password) option to useradd and usermod
1424 (idea from hpux10 - undocumented option used internally by SAM)
1425 - useradd -D -e does the right thing (set default expiration date)
1426 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1427 because there are just too many systems that need different commands
1428 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1429 faillog file format has been changed (somewhere between 960129 and
1430 960810), please truncate the old file (if any) to zero length
1431 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1432 - wtmp, lastlog, faillog file location guessed by configure
1433 - separate checks for invalid user and group names, max username length
1434 based on struct utmp (it's not always 8 characters)
1435 - pwck and grpck now check for invalid user/group names
1436 - pwck -q (quiet, report only serious problems) option added
1437 - separate cleaner sgetpwent() without the NIS magic
1438 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1439 - various code cleanups
1440 - new get_my_pwent() function for getting my own username, uid etc.
1441 - faillog opens the file read-write if possible (even if not root)
1442 - passwd -S allowed for normal users (for their own uid only)
1443 - handle the case of login denied to passwordless accounts better
1444 ("Login incorrect" without "Password:" prompt looks strange)
1445 - corrected author information and removed a copyright restriction
1447 shadow-960925 => shadow-961025
1449 - fixed a few typos in shadow group code
1450 - don't check for names starting with 'r' to determine if the shell
1451 is restricted, use /etc/shells instead (for the "rc" shell)
1452 - removed extra definition of LASTLOG_FILE in configure.in
1453 - expiry no longer segfaults if no /etc/shadow
1454 - userdel -r "can't remove mailbox" warning no longer printed on success
1455 - useradd exit codes changed to match hpux10 man page
1456 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1458 shadow-960920 => shadow-960925
1460 - bug fixes to the new environment code using malloc
1461 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1462 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1463 - small fix to isexpired(), and use it in passwd as well
1464 - use strftime() and strptime() if available
1465 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1466 contain encrypted passwords!)
1467 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1468 (nothing bad happened yet, just a cleanup)
1469 - gpasswd should work with both shadow and non-shadow group passwords
1470 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1471 - passwd -e for sunos4 (ATT_AGE), untested
1472 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1473 - small fix to l64a()
1474 - passwd prints a message after password successfully changed (for things
1475 like poppassd which run passwd and expect some output)
1476 - passwd logs if password was changed by root (as opposed to a luser)
1477 - passwd uses current uid if no username argument and getlogin() fails
1479 shadow-960910 => shadow-960920
1481 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1482 - newusers should work with both shadow and non-shadow passwords
1483 (still left to do: chpasswd, gpasswd)
1484 - login-static no longer compiled by default
1485 - more SYSLOG() macros
1487 shadow-960810 => shadow-960910
1489 - updated README.linux to point to the new ftp site
1490 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1491 - man pages now closer to LDP standards (Ivan Nejgebauer)
1492 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1493 - obscure.c fixed to compile with HAVE_LIBCRACK
1494 - cosmetic message changes in age.c
1495 - utmp open error check fixed in utmp.c
1496 - grpunconv added (Michael Meskes)
1497 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1498 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1499 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1500 - passwords can be changed if sp_max == -1 (now considered infinity)
1501 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1502 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1503 - contrib/rpasswd.c added (Joshua Cowan)
1504 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1505 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1506 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1508 shadow-960129 => shadow-960810
1510 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1511 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1512 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1513 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1514 - hopefully removed all the rcsid warnings
1515 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1516 - resource limits (Cristian Gafton)
1517 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1518 - more fixes in man pages
1519 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1520 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1521 su, useradd, userdel, usermod) should now work with both shadow and
1522 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1523 run time); a few programs still left to do
1524 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1525 - new contrib/adduser.c from Chris Evans
1526 - lots of other minor changes
1527 - source tree reorganization, GNU autoconf, portability cleanups
1528 - basename() renamed to Basename() to avoid name space confusion
1529 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1530 - newgrp cleanup and a few fixes
1531 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1532 - don't make the first group member the group admin by default
1533 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1534 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1535 place (defines.h) instead of repeating it in all source files...
1536 - added userdel -r safety check (refuse to remove the home directory
1537 if it would result in removing some other user's home directory)
1538 - usermod -u now correctly checks for non-unique uid (unless -o)
1539 - sync() after updating password files, just to be more safe
1540 - "make install" should install /etc/login.defs if it doesn't exist
1541 - new option to control what happens if we can't cd to the home directory
1542 (DEFAULT_HOME in /etc/login.defs)
1543 - enter the home directory as the user, not as root (for NFS etc.)
1544 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1545 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1546 possible to add specified groups (floppy etc.) for console logins
1547 - new faillog feature: lock account for specified (per-user) time since
1548 the last failure after exceeding the failure limit
1549 - new man pages (gpasswd.1, login.access.5, suauth.5)
1550 - fixes in man pages, renamed *.4 to *.5
1551 - new "contrib" directory (two adduser programs)
1552 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1553 - sulogin no longer requires to be run from init, should work from rc
1555 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1556 using xx_locate(), modify it and call xx_update(), don't write back
1557 anything returned by getpwnam() etc.)
1558 - stupid bug fixed in lastlog.c
1559 - don't move non-directories in "usermod -m"
1560 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1561 - macros to get around ancient compilers which don't like prototypes
1562 - make more use of "const" (not everywhere yet)
1563 - added #ifdef AUTH_METHODS - very few people use administrator defined
1564 authentication methods because many programs are not aware of them;
1565 not supporting them makes the code simpler
1566 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1567 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1568 see HAVE_SGETGRENT in config.h (grent.c)
1569 - don't use continued lines in /etc/group, the standard getgr*() functions
1570 don't support that (grent.c)
1571 - removed the third main() argument (according to libc docs, not allowed by
1572 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1573 - login access control (lmain.c, login_access.c)
1574 - added copyright notice to login_access.c (from logdaemon-5.0)
1575 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1576 - added closelog() in su before executing the shell (smain.c)
1577 - getting current user name changed (smain.c)
1578 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1579 - getpass() shouldn't return NULL except on errors (getpass.c)
1580 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1581 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1582 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1583 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1584 - "no shadow password" not logged, the same /bin/login should work with both
1585 shadow and non-shadow passwords (lmain.c)
1586 - some cleanup in various places (lmain.c, passwd.c)
1587 - new program to verify username/password pairs, for xlock etc.; it is not
1588 installed by default, read the comments first (pwdauth.c)
1589 - authentication programs run with empty environment for safety (pwauth.c)
1590 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1591 - common code separated from *io.c (commonio.c)
1592 - ownership and permissions on password files are now preserved (we may try
1593 to make more use of setgid and setuid non-root programs in the future)
1594 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1595 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
1596 - termios/termio/sgtty macros cleaned up a bit
1598 shadow-951218 => shadow-960129
1600 Emergency bug fix release - no new features since 951218. There are many
1601 new changes, but this bug really can't wait until they are tested.
1603 Probably all previous versions of the shadow suite have a serious bug which
1604 makes it possible to overwrite the stack by entering very long username at
1605 the login prompt. This can give root access to any remote user!
1607 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
1608 size of the array in lmain.c). Aaargh!!!
1610 shadow-951203 => shadow-951218
1613 - Linux utmp handling fixes (utmp.c)
1614 - last failure date printing fixes (failure.c)
1615 - minor fix to compile with USE_CRACKLIB (obscure.c)
1616 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
1617 - basename.c added, replacing duplicated code in various places
1618 - "su -" runs the shell with '-' in argv[0] again (smain.c)
1619 - removing at/cron jobs cleaned up (userdel.c)
1620 - /etc/gshadow should not be world-readable (sgroupio.c)
1621 - if fflush() failed, files were not closed (*io.c)
1622 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
1623 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
1624 - some minor cleanups for gcc -Wall (unused variables etc.)
1625 - removed README.FIRST (copyrights are OK now)
1626 - updated ANNOUNCE, README.linux, WISHLIST
1627 - as suggested, converted to RCS
1629 shadow-3.3.2-951127 => shadow-951203-jfh
1632 - Added the BSD-style copyright to all of the files. Any files with the
1633 old copyright have multiple copyright holders and need to be cleanroomed
1634 to produce BSD-style copyrightable files, or I need to get the consent
1635 of the others to change the copyright.
1636 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
1637 that all of the files should have the correct copyright there is no need
1638 to refer to that e-mail message.
1639 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
1640 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
1642 jfh@rpp386.cactus.org
1644 shadow-3.3.2-951106 => shadow-951127
1646 Note: for now this code only supports Linux. All the #ifdef's are there
1647 (and will be; support for at least SunOS 4.1.x would be nice) but:
1648 - I had to fix some potential security problems resulting from sloppy
1649 coding (no bounds checking), and it was easier for me to use snprintf()
1650 (not available on many systems, unfortunately), I'll fix that later.
1651 Old versions of Linux libc don't have snprintf() either, and the one
1652 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
1653 - I am lazy and only updated Makefile.linux and config.h.linux this time
1654 - I don't have root access to non-Linux systems (this means no testing)
1655 - this code needs some major reorganization, which will (hopefully)
1659 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
1660 - login can be statically linked (not that I think it's a good idea, better
1661 fix the telnetd, but paranoid people will like it :-)
1662 - login is installed non-setuid by default
1663 - check for NULL from getpass()
1664 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
1665 - use standard "Password: " prompt by default (pwauth.c)
1666 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
1667 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
1668 - Linux has <lastlog.h>
1669 - print ll_host on Linux too (lmain.c)
1670 - size checking in various places (setuid root programs, argh!)
1671 - preserve TERM from getty (lmain.c)
1672 - don't ignore SIGHUP (lmain.c)
1673 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
1674 - remove LD_xxx (env.c)
1675 - use bzero() instead of memset() for BSD portability and less #ifdef's
1676 (if the system has no bzero(), implement it as a macro using memset())
1677 - the above fixes wrong order of memset() parameters (log.c)
1678 - use getutent/pututline instead of doing it by hand (utmp.c)
1679 - added the new settings to login.defs.linux
1680 - added login_access.c to the distribution (not used yet)
1684 shadow-3.3.2 => shadow-3.3.2-951106
1686 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
1687 - malloc/strdup error checking, hopefully no more core dumps...
1688 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
1689 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
1690 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
1691 - use POSIX termios whenever possible on Linux
1692 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
1693 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
1694 - login -h only for root (lmain.c)
1695 - login -r not needed for Linux (lmain.c)
1696 - sample login.defs modified for Linux (login.defs.linux)
1697 - swapped chfn USAGE and ADMUSAGE (chfn.c)
1698 - added -u to passwd usage (passwd.c)
1699 - no #! check necessary for Linux (shell.c)
1700 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
1701 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
1702 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
1703 can now be set in login.defs, old values are used as defaults (lmain.c)
1704 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
1705 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
1706 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
1707 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
1708 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
1709 - check for weak passwords too if previous password was empty (obscure.c)
1710 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
1711 - Linux has getusershell(), use it (chsh.c)
1712 - check if the new shell is executable by the user (chsh.c)
1713 - sleep before printing "Login incorrect", not the other way around (lmain.c)
1714 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
1715 - do "wheel group" more like BSD does (smain.c)
1716 - use getlogin() in su (smain.c)
1717 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
1718 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
1719 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
1720 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
1721 - LOGIN_STRING should work now (pwauth.c, getdef.c)
1722 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
1723 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
1724 not lost when you copy the right ones to Makefile and config.h
