3 shadow-4.1.0 -> shadow-4.1.1 UNRELEASED
7 * Do not seed the random number generator each time, and use the time in
8 microseconds to avoid having the same salt for different passwords
9 generated in the same second.
11 * Do not install the shadow library per default.
13 * Do not translate the messages sent to syslog. This avoids logging
14 PAM error messages in the users's locale.
16 * Set GID_MIN to the same value as UID_MIN by default (1000).
17 * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
18 SYS_GID_MAX (999) for system accounts.
20 * /etc/default/useradd now defines HOME as /home to match FHS.
22 * Fix bug which forbid to set the aging information of an account with a
23 passwd entry, but no shadow entry.
25 * faillog -r now only reset the entries of existing users. This makes
28 * Fix failures when the gshadow file is not present.
29 * When a password is moved to the gshadow file, use "x" instead of "x"
30 to indicate that the password is shadowed (consistency with grpconv).
32 * New option -p/--password to specify an encrypted password.
33 * New option -r, --system for system accounts.
35 * Do not fail if the group does not exist in the gshadow file.
37 * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
39 * New option -p/--password to specify an encrypted password.
41 * Fix logging of changes to syslog when a group file is provided,
42 without a gshadow file.
44 * Accept users specified as a numerical UID, or ranges of users (-user,
47 * Use PATH and SUPATH to set the PATH environment variable, even when
48 support for PAM is enabled.
49 * If started as init, start a new session.
51 * Fix segfault when an user returns to an unknown GID (either the user
52 was deleted during the user's newgrp session or the user's passwd
53 entry referenced an invalid group). Add a syslog warning in that case.
54 * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
55 changing the user space group ID with newgrp or sg.
57 * The new users are no more added to the list of members of their groups
58 because the membership is already set by their primary group.
59 * Added support for gshadow.
60 * Avoid using the same salt for different passwords.
61 * Fix support for the NONE crypt method.
62 * newusers will behave more like useradd regarding the choice of UID or
63 GID or regarding the validity of user and group names.
64 * New option -r, --system for system accounts.
66 * Make sure that no more than one username argument was provided.
68 * Fix logging of changes to syslog when a passwd file is provided,
69 without a shadow file.
71 * su's arguments are now reordered. If needed, use -- to separate su's
72 options from the shell's options.
74 * If started as init, start a new session.
76 * New option -l to avoid adding the user to the lastlog and faillog databases.
77 * Fix the handling of the --defaults option (it required an argument,
78 but should behave as -D)
79 * Document the --defaults option, which was already described in the
80 useradd's Usage information.
81 * New option -r, --system for system accounts.
82 * New options -U, --user-group and -N, --no-user-group. These options
83 should replace nflg from the previous versions. Please set any -n
84 option to deprecated because its meaning differs from one distribution
87 * Keep the access and modification time of files when moving an user's home
89 * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
90 differ from the old ones. If a requested new value is equal to the old
91 one, no changes will be performed for that field. If no fields are
92 changed, usermod will exist successfully with a warning. This avoids
93 logging changes to syslog when there are actually no changes.
94 * Fix the handling of -a when a user is being renamed (with -l)
96 * Recommend editing the shadowed (resp. regular) file if the regular (resp.
97 shadowed) file was edited.
99 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2008
103 When compiled with PAM support, it used the chpasswd policy file instead
104 of the chgpasswd policy file. If an administrator added some restriction
105 to the chgpasswd policy file, they were not taken into account.
108 - Add support for SHA256 and SHA512 encrypt methods (supported by new
110 - useradd: Allow non numerical group identifier to be specified with
112 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
113 - newgrp: Do not give an indication that the group has no password. Ask
114 for the password, as if there were a password.
115 - The permissions of the suid binaries is now configurable in
116 src/Makefile.am. Note that changing the permissions is not recommended.
117 - newgrp.c: Declare the child and pid variable at the beginning of a block.
118 This fixes a compilation issue with gcc 2.95.
119 - login_nopam: Add support for systems with no innetgr(). On those
120 systems, username with an @ will be treated like any other username
121 (i.e. lookup in the local database for an user with an @). Thanks to
122 Mike Frysinger for the patch.
123 - Add support for uClibc with no l64a().
124 - userdel, usermod: Fix infinite loop caused by erroneous group file
125 containing two entries with the same name. (The fix strategy differs
127 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
128 - userdel: Abort if an error is detected while updating the passwd or group
129 databases. The passwd or group files will not be written.
130 - usermod: Update the group database before flushing the nscd caches.
131 - usermod: Make sure the group modifications will be allowed before
132 writing the passwd files.
133 - Flush the nscd tables using nscd -i instead of the private glibc socket.
134 - usermod: Make usermod options independent of the argument order.
135 - newgrp: Do not request a password when a user uses newgrp to switch to
137 - passwd: -l/-u options: edit the shadow account expiry field *in
138 addition* to editing the password field.
139 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
141 - su: Avoid terminating the PAM library in the forked child. This is done
142 later in the parent after closing the PAM session.
143 - userdel: Fix the homedir prefix checking.
144 - passwd, usermod: Refuse to unlock an account when it would result in a
145 passwordless account.
146 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
147 getgrgid(), and getspnam(). There should be no functional changes.
148 - gpasswd: Only read information from the local file group database. It
149 writes the changes in /etc/group and/or /etc/gshadow, but used to read
150 information from getgrnam (hence possibly from another group database).
151 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
152 better support for split groups. Be careful when using this variable:
153 not all tools support well split groups (in or out of the shadow
154 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
155 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
156 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
158 - chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
159 -s/--sha-rounds to supersede the system default encryption algorithm.
160 - chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
161 will respect the system default configured in /etc/login.defs
164 - Generate the translated manpages from PO at build time.
165 - The generated manpages will change depending on the configure options.
166 If you use different options than the one used for the distributed
167 archive, you should re-generate the manpages.
168 - login.defs should now describe all the variables.
169 - The tools' documentation details the login.defs variables they use.

179 after close /etc/{group,passwd} files,
180 - su: If compiled without PAM support, enforce the limits from /etc/limits
181 when one of the -, -l, or --login options is set, even if called by root.
182 - limits: Support for 2 new resource limits: max nice value, and max real

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

226 Dan Yefimov <dan@D00M.lightwave.net.ru>),
227 - removed using private implementation getpass() libc function
228 (now getpass() is used also when S/KEY support is enabled),

249 Rafal Wojtczuk <nergal@owl.openwall.com>),
250 - userdel: use login.defs::MAIL_DIR instead hardcoded /var/mail in created
251 mailbox path (based on Owl fixes submited
252 by Solar Designer <solar@openwall.com>),
253 - by default do not use libshadow_getpass() as getpass() replacemement.
254 Use libshadow_getpass() only when S/KEY support is enabled.
255 Current glibc getpass() handles correctly longer than 8 characters
256 passwords and libshadow_getpass() is used only because libc getpass()
257 do not handles password prompting with echo enabled,
258 - move login.defs::MD5_CRYPT_ENAB to non-PAM part,
259 - userdel: rewrited for use getopt_log(),
260 - install default/template configuration files:
261 -- if shadow is configured with use PAM install /etc/pam.d/* files,

377 (pointed by Peter Vrabec <pvrabec@redhat.com>),
378 - useradd(8): better document that -d will not add the user's home directory
379 if it does not already exist (http://bugs.debian.org/154996),
380 - nologin(8) man pages added (merge 478_nologin.8.xml Debian patch).
382 shadow-4.0.13 -> shadow-4.0.14 03-01-2006
385 - fixes in handling login.defs: $MAIL_FILE is used in userdel and usermod,
386 $MD5_CRYPT_ENAB is used by crypt_make_salt, which is used by chpasswd,
387 gpasswd and newusers.

618 - usermod: when relocating a user's home directory, don't fail and remove the new
619 home directory if we can't remove the old home directory for some
620 reason; the results can be spectularly poort if, for instance, only
621 the rmdir() fails. Patch prepared by Timo Lindfors <lindi-spamtrap@newmail.com>.
622 http://bugs.debian.org/166369

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

860 - added variouse cs, de, fr, id, it, ko man pages found mainly in national
861 man pages translations projects (this documents are not synced with
862 current en version but you know .. "Documentations is lik sex. When it is
863 good it very very good. Whet it is bad it is better than nothing."). Any
864 changes for syncing this are welcome and for anyone who will want maintain
865 this documents directly I can give cvs write access to project resources.

875 - resolve many fuzzy translations also all this which may cause problems on
876 displaing long uid/gid,
877 - allow use "$" on ending in cereated by useradd usermname accounts for allow
878 create machine acounts for samba (thanks to Jerome Borsboom

892 shadow-4.0.0-owl-chage-drop-priv.diffd
893 shadow-4.0.0-owl-chage-ro-no-lock.diff:
894 Added locks which are needed when doing r/w accesses, not when running
895 as root. If root does read-only, there's no lock needed. Added missing
896 "#include <errno.h>" for above (me).
897 shadow-4.0.0-owl-warnings.diff
898 Olny one fix from this patch was aplayd because other was fixed few days
900 shadow-4.0.0-owl-check_names.diff
901 Merge only prat this patch with checking login name matching; checking
902 is login string isn't longer than possible it will be good prepare using
903 probably _POSIX_LOGIN_NAME_MAX from <bits/posix1_lim.h>,
904 shadow-4.0.0-owl-chage-drop-priv.diff
905 shadow-4.0.0-owl-pam-auth.diff
906 Merge part with reorder initialize PAM and checkin is chage is runed by
907 root or not - now chage can be runed from non-root account for checking
908 by user own account information (if PAM enabled).
909 - fixes for handle/print correctly 32bit uid/gid (Thorsten Kukuk <kukuk@suse.de>),
910 - implemented functions for better reloading the nscd cache (per NSS map)
911 (Thorsten Kukuk <kukuk@suse.de>),
912 - fixed warnings "not used but defined" on compile using gcc 3.0.x
913 (bulletpr00ph <bullet@users.sourceforge.net>),

918 - installed fix for SEGV when using pwck -s on /etc/passwd file with
921 shadow-20001016 => shadow-4.0.0 06-01-2002
923 - fix bug discovered and fixed by Marcel Ritter
924 <Marcel.Ritter@rrze.uni-erlangen.de>
925 Due to a big buffer size in lib/commonio.c this error does only appear
926 if a line gets longer than 4096 bytes (there are probably very few people
927 stumbling across this).
928 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
933 while [ $NUM -le 1000 ]; do
934 useradd -g demogroup -G demogroup -p "NONE" user$NUM
937 - remove limit 32 to groups per user by (the same user can belong to
938 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
939 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
940 NOTE: it probably need testing on other system for add
941 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
942 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
943 - drop detecting is pam_strerror() need one or two arguments. Instead using
944 PAM_STRERROR() macro use directly pam_strerror() function with two
945 arguments. pam_strerror() with one argument is obsoleted,
946 - adde ja man pages (probably some man pages need update),
947 - much better automake support,
948 - added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
949 groupmod(8), shadow(5) (man pages for other nations also are welcome),
950 - mamny small fixes and updates nad improvements in man pages,
951 - aplayed Debian patch to man pages for shadowconfig,
952 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
955 shadow-20001012 -> shadow-20001016:
956 - conditionaly disabled body reload_nscd() because not every
957 version of nscd can handle it (this can be enabled by define
958 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
959 - fixes on autoconf/automake level for dist target,
960 - Julianne F. Haugh new contact adress.
962 shadow-20000902 => shadow-20001012
964 - removed /redhat directory with obsoleted files (partialy rewrited spec
965 file is now in root directory),
966 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
967 overwrite previously existing groups in adduser,
968 - added PAM support for chage (bind to "chage" PAM config file) also
969 added PAM support for all other small tools like chpasswd, groupadd,
970 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
971 "shadow" PAM config file) - this modificaytions mainly based on
972 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
973 - many small fixes and improvments in automake (mow "make dist"
975 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
977 shadow-20000826 => shadow-20000902
979 This is probably the last release from me.
980 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
983 (I'm still interested to know what is going on with this package,
984 which is fairly important to many Linux distributions, so please
985 Cc: marekm@linux.org.pl in any related discussions - just don't
986 expect me to respond quickly...)
988 Previous warning still applies - be careful!
990 - applied some of the Red Hat patches (revised slightly), thanks to
991 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
992 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
993 in glibc 2.1.x) after changing anything, add usermod -L and -U
994 options, remove LOG_CONS from openlog(), chage -d and -E handles
995 dates in yyyy-mm-dd format ('/' is not required)
998 shadow-19990827 => shadow-20000826
1000 WARNING: this release is not tested (other than that it compiles for me),
1001 please be careful. Previous release was a year ago, so it is really time
1002 to release something and start looking for a new, better maintainer...
1003 (I've been extremely busy recently. Credit for most of the real work,
1004 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
1005 who maintains this package for Debian.)
1007 - merged most of the changes from Debian (not all of them yet, PAM support
1008 should be complete but is not tested - need to upgrade to potato first)
1009 - added Polish translations of manual pages from PLD
1010 - change sulog() to not depend on global variables oldname, name
1011 - try to not follow symbolic links when deleting files recursively
1012 in userdel (still not perfect, safest to do it in single user mode)
1013 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
1014 (a few ANSI C constructs were used already, and no one complained)
1015 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
1017 shadow-19990709 => shadow-19990827

1021 - i18n: added Swedish translation by Kristoffer Brånemyr <ztion@swipnet.se>
1022 - logoutd no longer reads /etc/logoutd.mesg at startup - instead, read
1023 it when sending to luser's tty (no need to reload with SIGHUP)
1024 - added support for "usergroups" feature often found in Linux distributions
1025 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
1026 username == groupname, then set umask to 002 instead of 022)
1027 - Debian: pwck and grpck are now run from a daily cron job (root will
1028 receive an e-mail if something is wrong), and at system startup
1029 - added support for setting umask in /etc/limits
1030 - when using OPIE, re-prompt with echo on after empty password was entered
1031 - GETPASS_ASTERISKS now run time configurable (login.defs)
1032 - getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
1033 - getpass() allows all input to be erased using Control-U, and beeps when
1034 too many characters are entered
1035 - removed obsolete sgtty support, in 1999 everyone should have termios :)
1036 - Debian: tar wrapper no longer needed to build packages as non-root user
1037 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
1038 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
1039 dpkg-architecture, cross compilation, only build passwd, add
1040 etc/login.defs.hurd conffile, conditionalize CBAUD
1041 - newgrp sets $HOME before running the new shell
1042 - both "sg group command" (usage message) and "sg group -c command"
1043 (man page) work, updated both the usage message and the man page :)
1044 - i18n: added missing _() for some translatable strings
1046 shadow-19990607 => shadow-19990709
1048 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
1049 - fixed a bug in newgrp if the user is in >= 17 groups
1050 - added @LIBSKEY@ to LDADD for all programs (for some reason,
1051 almost all programs need it if skey/opie support is enabled)
1052 - changed grpconv/grpunconv to compile with --disable-shadowgrp
1053 - changed faillog to do something (assume -p) with no options specified
1054 - updated version of the udbachk passwd/shadow/group file integrity
1055 checker (contrib/udbachk.v012.tgz)

1063 - added some braces to if/else to avoid egcs warnings
1064 - started adding PAM support to login (based on util-linux, not finished yet)
1065 - changed "!" to "x" for pw_passwd in src/newusers.c
1066 - a few more Y2K fixes
1067 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
1068 thanks to Sami Kerola
1069 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
1070 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
1071 - updated mailing list information (moved again, now hosted by SuSE),
1072 updated README.mirrors, other minor documentation updates
1073 - made getpass work with redirected stdin
1074 - new readpass echoing asterisks disabled by default by popular demand
1075 (can be enabled at compile time: ./configure --enable-readpass)
1076 - the random number of asterisks in readpass is now more random
1077 (random number generator initialization was missing)
1078 - commented out --enable-md5crypt (obsolete) in configure.in
1079 - when checking for libskey, link with -lcrypt if libcrypt is available
1080 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1081 - added Package/Version ident strings (so you can use the RCS "ident"
1082 command to check any binary, which version of shadow it comes from)
1084 shadow-981228 => shadow-19990307
1086 - added support for setting process priority in /etc/limits
1087 - i18n: updated Greek translation
1088 - i18n: added Polish translation by Arkadiusz Miskiewicz

1093 - always require password for root logins (even with NO_PASSWORD_CONSOLE)
1094 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1095 - changed to Y2K compatible version numbering
1096 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1097 values of user-entered dates (you can still enter dates in any format
1098 supported by GNU date)
1099 - oops, added doc/README.nls to list of files to distribute
1100 - added missing sanitize_env() call to src/login.c
1101 - debian/rules installs /bin/login non-setuid by default, just in case...
1102 - build Debian packages with cracklib support (depends on cracklib-runtime)
1104 shadow-980724 => shadow-981228
1106 - login now clears the username in argv[] (in case someone types the
1107 password instead of username, by mistake)
1108 - i18n support, Greek translation (Nikos Mavroyanopoulos), see README.nls
1109 - updated author's e-mail address (jfh@tab.com -> jfh@bga.com)
1110 - new getpass() replacement that displays *'s (Pavel Machek)
1111 - no password required when logging in from ttys listed under
1112 NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
1113 - fixed limits code so RLIMIT_AS should work
1114 - upgraded to Debian 2.0
1115 - built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
1116 in reasonable time again
1117 - upgraded to automake-1.3, libtool-1.0h (also new config.guess and
1118 config.sub that work on i686)
1119 - usermod fixed to handle group names starting with digits (not recommended)
1121 shadow-980626 => shadow-980724
1123 - security: login no longer gives you a root shell if setgid()
1124 or initgroups() or setuid() fails for any reason, discovered
1125 by Ted Hickman <thickman@sy.net>
1126 - remove libshadow.so -> libshadow.so.x.x symlink after install
1127 - a few int -> uid_t type cleanups
1128 - fail immediately (don't retry) in *_lock() if euid != 0
1129 - added sample PAM config files etc/pam.d/{passwd,su}
1130 - preliminary PAM support in su (untested - use at your own risk,
1131 comments and patches welcome!)
1132 - cleanup and more comments in OPIE code (Algis Rudys)
1133 - added support for TCFS (Transparent Cryptographic File System)
1134 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/
1135 for more info), thanks to Aniello Del Sorbo
1137 shadow-980529 => shadow-980626
1139 - fixed bug in commonio_lock() (infinite recursion if lckpwdf() not
1140 used and database cannot be locked), thanks to Jonathan Hankins
1141 - fixed bug in copy_tree() (NUL-terminate readlink() results),
1142 thanks to Lutz Schwalowsky
1143 - no need to press Enter after Ctrl-C to interrupt password prompt
1144 - removed a few harmless gcc warnings
1145 - secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)
1146 - faillog.8: changed /usr/adm -> /var/log
1147 - pwconv.8: documented that it may fail on invalid password files
1149 shadow-980417 => shadow-980529
1151 - fixed "interesting" strzero() bug introduced by me in 980417:
1152 strzero(cp) didn't work as intended (the macro used a local
1153 variable called "cp" - oops...); Leonard N. Zubkoff was the
1154 first person to report it - thanks!
1155 - fixed usermod -e to accept empty argument (like useradd),
1156 thanks to Martin Bene
1157 - several changes from Debian 980403-0.2, see debian/changelog
1158 - added contrib/shadow-anonftp.patch (not yet merged, sorry...)
1159 thanks to Calle Karlsson
1161 shadow-980403 => shadow-980417
1163 - fixed login session limits (again - broken since 980130)
1164 - more symbolic constants for exit status values
1165 - fixed logoutd to work with 8-character usernames in utmp
1166 (no room for terminating NUL!)
1167 - various fixes to make the code more glibc2-friendly
1168 - updated doc/cracklib26.diff (fix for empty gecos, etc.)
1169 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1172 shadow-980130 => shadow-980403
1174 - security: su now creates the sulog file (if enabled and doesn't
1175 already exist) with umask 077
1176 - hopefully removed arbitrary group size limits (not yet for
1177 shadow groups though - sgetsgent() still needs a rewrite,
1178 but I don't want to delay this release any longer...)
1179 - fixed NULL dereference in groupmod -n
1181 shadow-971215 => shadow-980130
1183 - Debian binary packages can be built without root privileges
1184 (tar wrapper - debian/tar.c)
1185 - new subdir "redhat" (needs more work, see redhat/README)
1186 - in several places, exit(127) if exec fails with ENOENT, and
1187 exit(126) on other errors (as in ksh and bash)
1188 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1189 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1190 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1191 - handle crypt() returning NULL (possible according to Single Unix
1192 Spec) more gracefully (exit instead of SIGSEGV)
1193 - fixed bug in putgrent() that showed up when realloc() moved the
1194 buffer while expanding it, thanks to Floody <flood@evcom.net>
1195 - fixed bug in login session limits (with a limit set to N logins,
1196 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1197 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1198 - newer config.guess and config.sub (should work on x86 for x > 5)
1199 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1200 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1201 - documented more (not all yet) login.defs(5) settings
1202 - replaced more exit status numeric values with #defines
1203 - shadow-utils.spec now generated from shadow-utils.spec.in
1204 (so I don't have to edit version numbers for every new release)
1205 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1206 ("force" - exit(0) if the group already exists); other RedHat-
1207 specific options not added yet (best done in a perl script that
1208 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1209 - added -O option (override login.defs values) to useradd and groupadd
1210 - if usermod can't update the group file(s), exit(10) but update the
1211 password file(s) anyway (as documented by Solaris man page)
1212 - useradd should no longer set sp_expire to the current date (oops)
1213 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1214 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1215 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1216 detection, setpgrp vs. setpgid, other minor tweaks
1217 - various */Makefile.am tweaks
1218 - login.defs: added FAKE_SHELL - program to run instead of the login
1219 shell, with the real shell in argv[0] (Frank Denis)
1220 - login.defs: ignore case in yes/no settings
1221 - more E_* defines instead of hardcoded numbers for exit()
1222 - added sanitize_env() for setuid programs
1223 - login_desrpc() checks for getnetname() errors
1224 - new password is not "too similar" if it is long enough
1225 - replacement strstr() was static, no one noticed :-)
1226 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1227 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1228 - login sets $REMOTEHOST for remote logins
1229 - added newgrp -l option (Single Unix Spec, same as "-")
1230 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1231 200K of disk space on Linux/x86), enabled by default if supported by
1232 the system, use ./configure --disable-shared if it causes any problems.
1233 Warning: libshadow.so is intended for internal use by this package
1234 only - binary compatibility with future releases is not guaranteed.
1235 There should be no need to link any other programs with libshadow.so -
1236 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1237 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1238 version (!) - added check to configure; fixed do_pam_passwd prototype
1239 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1240 - added information about the new ftp site to doc/README.mirrors
1242 shadow-971001 => shadow-971215
1244 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1245 - updated the RPM .spec file
1246 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1247 (glibc defines something else named "rlogin" in utmpbits.h ?)
1248 - added MD5 checksums in Debian packages
1249 - added -p and -g options to vipw (edit the password or group file
1250 respectively, regardless of the command name in argv[0])
1251 - removed old DBM support (NDBM code is still there)
1252 - fixed a bug in gpasswd: current username was incorrectly identified as
1253 "root" because of setuid(0) done too early. It may be a security hole
1254 when using shadow groups - if "root" is listed as a group administrator,
1255 any user can add/remove members in that group. Thanks to Jesse Thilo.
1256 - gpasswd now logs which user (root or group admin) made the changes
1257 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1258 - newgrp and add_groups() allocate supplementary group lists dynamically
1259 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1260 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1261 changed by regular users (any combination of letters "frwh")
1262 - fixed contrib/pwdauth.c segfault with non-existent usernames
1263 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1264 - new date parsing code (from GNU date) used by useradd, usermod, chage
1265 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1266 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1267 - fixed useradd -G segfault (one '*' that shouldn't be there)
1268 - allow 8-bit characters in chfn
1269 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1270 - changed the handling of NIS plus entries in password files
1271 - some more tweaking in various debian/* files
1272 - logoutd uses getutent() instead of reading utmp file directly
1273 - fixed lckpwdf() called twice (and failing) when changing password
1274 if the user is not listed in /etc/shadow (Mike Pakovic)
1275 - erase and kill characters left unchanged if not defined in login.defs
1277 shadow-970616 => shadow-971001
1279 - Debian: mkpasswd no longer installed (dbm files not supported)
1280 - chpasswd checks for shadow/non-shadow at run time, too
1281 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1282 - changed libmisc/login_access.c as suggested by Dave Hagewood
1283 - replaced sprintf() with snprintf() in several places
1284 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1285 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1286 - non-root users can only run su with a terminal on stdin
1287 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1288 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1289 in libc, or system misconfiguration. Needs further investigation.
1290 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1291 - fixed free() called twice in libmisc/mail.c
1292 - added information about mirror sites (doc/README.mirrors)
1293 - updated pwconv.8 and pwunconv.8 man pages
1294 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1295 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1296 - corrected su.1 man page ($SHELL not used)
1297 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1298 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1299 - cleaned up PASS_MAX in getpass() (127 always assumed)
1300 - default editor for vipw changed from /bin/ae to a real editor :)
1302 shadow-970601 => shadow-970616
1304 - fixed execlp call (missing NULL) in src/vipw.c
1305 - vipw now preserves permissions on edited files
1306 - commented out the xdm-shadow hack in shadowconfig
1307 - improved RedHat spec file (Timo Karjalainen)
1308 - updated mailing list information
1309 - added information about the shadow paper (doc/README.shadow-paper)
1310 - renamed doc/console.c.spec (confused RPM)
1312 shadow-970502-2 => shadow-970601
1314 - fixed a typo in libmisc/mail.c causing login to segfault
1315 if MAIL_CHECK_ENAB=yes (sorry!)
1316 - patches for OPIE support (Algis Rudys) (untested)
1317 - programs that modify /etc/passwd or /etc/shadow will use
1318 lckpwdf() if available
1319 - now compiles with PAM support! (still untested)
1320 - cosmetic error message changes (prefixed by argv[0]:)
1322 shadow-970216 => shadow-970502-2
1324 - shadow group support fixes (grpconv didn't work - for some
1325 reason, putsgent() returns 1 instead of 0 on success;
1326 now -1 = failure, anything else = success)
1327 - upgraded to autoconf-2.12
1328 - pwconv and pwunconv now follow other UN*X systems and SVID3
1329 (modify files in place), original versions moved to "old"
1330 - scologin.c moved to "old" (it was only for SCO Xenix) so
1331 people stop sending patches for scologin.c gcc warnings :)
1332 - don't use the MD5* functions in libmisc/salt.c (glibc has
1333 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1334 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1335 - "passwd -S -a" now really works
1336 - support for Debian, vipw, a few fixes (Guy Maor)
1337 - src/login.c radius bug fix (Rafal Maszkowski)
1338 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1339 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1340 - limits.5 man page (Luca Berra)
1341 - expiry will work setgid shadow too, removed euid 0 check
1342 - added check for a64l() to configure (glibc)
1344 shadow-961025 => shadow-970216
1346 - major rewrite of *io.c (no more 4 copies of almost identical code)
1347 - use fsync() (if available) instead of sync() when updating password files
1348 - use fchmod() and fchown() if available
1349 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1350 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1351 - passwd -S -a: list information about all users (root only)
1352 - passwd -k: change only expired passwords
1353 - passwd -q: quiet mode
1354 - first attempt at PAM support in passwd
1355 - passwd updates the non-shadow password if /etc/shadow exists but the
1356 user has no shadow password
1357 - passwd logs who changed the password, added hook to allow non-root
1358 administrators who can change passwords (not implemented yet)
1359 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1360 - added -p (set encrypted password) option to useradd and usermod
1361 (idea from hpux10 - undocumented option used internally by SAM)
1362 - useradd -D -e does the right thing (set default expiration date)
1363 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1364 because there are just too many systems that need different commands
1365 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1366 faillog file format has been changed (somewhere between 960129 and
1367 960810), please truncate the old file (if any) to zero length
1368 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1369 - wtmp, lastlog, faillog file location guessed by configure
1370 - separate checks for invalid user and group names, max username length
1371 based on struct utmp (it's not always 8 characters)
1372 - pwck and grpck now check for invalid user/group names
1373 - pwck -q (quiet, report only serious problems) option added
1374 - separate cleaner sgetpwent() without the NIS magic
1375 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1376 - various code cleanups
1377 - new get_my_pwent() function for getting my own username, uid etc.
1378 - faillog opens the file read-write if possible (even if not root)
1379 - passwd -S allowed for normal users (for their own uid only)
1380 - handle the case of login denied to passwordless accounts better
1381 ("Login incorrect" without "Password:" prompt looks strange)
1382 - corrected author information and removed a copyright restriction
1384 shadow-960925 => shadow-961025
1386 - fixed a few typos in shadow group code
1387 - don't check for names starting with 'r' to determine if the shell
1388 is restricted, use /etc/shells instead (for the "rc" shell)
1389 - removed extra definition of LASTLOG_FILE in configure.in
1390 - expiry no longer segfaults if no /etc/shadow
1391 - userdel -r "can't remove mailbox" warning no longer printed on success
1392 - useradd exit codes changed to match hpux10 man page
1393 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1395 shadow-960920 => shadow-960925
1397 - bug fixes to the new environment code using malloc
1398 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1399 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1400 - small fix to isexpired(), and use it in passwd as well
1401 - use strftime() and strptime() if available
1402 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1403 contain encrypted passwords!)
1404 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1405 (nothing bad happened yet, just a cleanup)
1406 - gpasswd should work with both shadow and non-shadow group passwords
1407 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1408 - passwd -e for sunos4 (ATT_AGE), untested
1409 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1410 - small fix to l64a()
1411 - passwd prints a message after password successfully changed (for things
1412 like poppassd which run passwd and expect some output)
1413 - passwd logs if password was changed by root (as opposed to a luser)
1414 - passwd uses current uid if no username argument and getlogin() fails
1416 shadow-960910 => shadow-960920
1418 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1419 - newusers should work with both shadow and non-shadow passwords
1420 (still left to do: chpasswd, gpasswd)
1421 - login-static no longer compiled by default
1422 - more SYSLOG() macros
1424 shadow-960810 => shadow-960910
1426 - updated README.linux to point to the new ftp site
1427 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1428 - man pages now closer to LDP standards (Ivan Nejgebauer)
1429 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1430 - obscure.c fixed to compile with HAVE_LIBCRACK
1431 - cosmetic message changes in age.c
1432 - utmp open error check fixed in utmp.c
1433 - grpunconv added (Michael Meskes)
1434 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1435 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1436 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1437 - passwords can be changed if sp_max == -1 (now considered infinity)
1438 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1439 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1440 - contrib/rpasswd.c added (Joshua Cowan)
1441 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1442 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1443 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1445 shadow-960129 => shadow-960810
1447 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1448 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1449 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1450 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1451 - hopefully removed all the rcsid warnings
1452 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1453 - resource limits (Cristian Gafton)
1454 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1455 - more fixes in man pages
1456 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1457 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1458 su, useradd, userdel, usermod) should now work with both shadow and
1459 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1460 run time); a few programs still left to do
1461 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1462 - new contrib/adduser.c from Chris Evans
1463 - lots of other minor changes
1464 - source tree reorganization, GNU autoconf, portability cleanups
1465 - basename() renamed to Basename() to avoid name space confusion
1466 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1467 - newgrp cleanup and a few fixes
1468 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1469 - don't make the first group member the group admin by default
1470 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1471 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1472 place (defines.h) instead of repeating it in all source files...
1473 - added userdel -r safety check (refuse to remove the home directory
1474 if it would result in removing some other user's home directory)
1475 - usermod -u now correctly checks for non-unique uid (unless -o)
1476 - sync() after updating password files, just to be more safe
1477 - "make install" should install /etc/login.defs if it doesn't exist
1478 - new option to control what happens if we can't cd to the home directory
1479 (DEFAULT_HOME in /etc/login.defs)
1480 - enter the home directory as the user, not as root (for NFS etc.)
1481 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1482 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1483 possible to add specified groups (floppy etc.) for console logins
1484 - new faillog feature: lock account for specified (per-user) time since
1485 the last failure after exceeding the failure limit
1486 - new man pages (gpasswd.1, login.access.5, suauth.5)
1487 - fixes in man pages, renamed *.4 to *.5
1488 - new "contrib" directory (two adduser programs)
1489 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1490 - sulogin no longer requires to be run from init, should work from rc
1492 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1493 using xx_locate(), modify it and call xx_update(), don't write back
1494 anything returned by getpwnam() etc.)
1495 - stupid bug fixed in lastlog.c
1496 - don't move non-directories in "usermod -m"
1497 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1498 - macros to get around ancient compilers which don't like prototypes
1499 - make more use of "const" (not everywhere yet)
1500 - added #ifdef AUTH_METHODS - very few people use administrator defined
1501 authentication methods because many programs are not aware of them;
1502 not supporting them makes the code simpler
1503 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1504 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1505 see HAVE_SGETGRENT in config.h (grent.c)
1506 - don't use continued lines in /etc/group, the standard getgr*() functions
1507 don't support that (grent.c)
1508 - removed the third main() argument (according to libc docs, not allowed by
1509 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1510 - login access control (lmain.c, login_access.c)
1511 - added copyright notice to login_access.c (from logdaemon-5.0)
1512 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1513 - added closelog() in su before executing the shell (smain.c)
1514 - getting current user name changed (smain.c)
1515 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1516 - getpass() shouldn't return NULL except on errors (getpass.c)
1517 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1518 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1519 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1520 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1521 - "no shadow password" not logged, the same /bin/login should work with both
1522 shadow and non-shadow passwords (lmain.c)
1523 - some cleanup in various places (lmain.c, passwd.c)
1524 - new program to verify username/password pairs, for xlock etc.; it is not
1525 installed by default, read the comments first (pwdauth.c)
1526 - authentication programs run with empty environment for safety (pwauth.c)
1527 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1528 - common code separated from *io.c (commonio.c)
1529 - ownership and permissions on password files are now preserved (we may try
1530 to make more use of setgid and setuid non-root programs in the future)
1531 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1532 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
1533 - termios/termio/sgtty macros cleaned up a bit
1535 shadow-951218 => shadow-960129
1537 Emergency bug fix release - no new features since 951218. There are many
1538 new changes, but this bug really can't wait until they are tested.
1540 Probably all previous versions of the shadow suite have a serious bug which
1541 makes it possible to overwrite the stack by entering very long username at
1542 the login prompt. This can give root access to any remote user!
1544 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
1545 size of the array in lmain.c). Aaargh!!!
1547 shadow-951203 => shadow-951218
1550 - Linux utmp handling fixes (utmp.c)
1551 - last failure date printing fixes (failure.c)
1552 - minor fix to compile with USE_CRACKLIB (obscure.c)
1553 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
1554 - basename.c added, replacing duplicated code in various places
1555 - "su -" runs the shell with '-' in argv[0] again (smain.c)
1556 - removing at/cron jobs cleaned up (userdel.c)
1557 - /etc/gshadow should not be world-readable (sgroupio.c)
1558 - if fflush() failed, files were not closed (*io.c)
1559 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
1560 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
1561 - some minor cleanups for gcc -Wall (unused variables etc.)
1562 - removed README.FIRST (copyrights are OK now)
1563 - updated ANNOUNCE, README.linux, WISHLIST
1564 - as suggested, converted to RCS
1566 shadow-3.3.2-951127 => shadow-951203-jfh
1569 - Added the BSD-style copyright to all of the files. Any files with the
1570 old copyright have multiple copyright holders and need to be cleanroomed
1571 to produce BSD-style copyrightable files, or I need to get the consent
1572 of the others to change the copyright.
1573 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
1574 that all of the files should have the correct copyright there is no need
1575 to refer to that e-mail message.
1576 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
1577 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
1579 jfh@rpp386.cactus.org
1581 shadow-3.3.2-951106 => shadow-951127
1583 Note: for now this code only supports Linux. All the #ifdef's are there
1584 (and will be; support for at least SunOS 4.1.x would be nice) but:
1585 - I had to fix some potential security problems resulting from sloppy
1586 coding (no bounds checking), and it was easier for me to use snprintf()
1587 (not available on many systems, unfortunately), I'll fix that later.
1588 Old versions of Linux libc don't have snprintf() either, and the one
1589 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
1590 - I am lazy and only updated Makefile.linux and config.h.linux this time
1591 - I don't have root access to non-Linux systems (this means no testing)
1592 - this code needs some major reorganization, which will (hopefully)
1596 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
1597 - login can be statically linked (not that I think it's a good idea, better
1598 fix the telnetd, but paranoid people will like it :-)
1599 - login is installed non-setuid by default
1600 - check for NULL from getpass()
1601 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
1602 - use standard "Password: " prompt by default (pwauth.c)
1603 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
1604 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
1605 - Linux has <lastlog.h>
1606 - print ll_host on Linux too (lmain.c)
1607 - size checking in various places (setuid root programs, argh!)
1608 - preserve TERM from getty (lmain.c)
1609 - don't ignore SIGHUP (lmain.c)
1610 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
1611 - remove LD_xxx (env.c)
1612 - use bzero() instead of memset() for BSD portability and less #ifdef's
1613 (if the system has no bzero(), implement it as a macro using memset())
1614 - the above fixes wrong order of memset() parameters (log.c)
1615 - use getutent/pututline instead of doing it by hand (utmp.c)
1616 - added the new settings to login.defs.linux
1617 - added login_access.c to the distribution (not used yet)
1621 shadow-3.3.2 => shadow-3.3.2-951106
1623 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
1624 - malloc/strdup error checking, hopefully no more core dumps...
1625 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
1626 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
1627 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
1628 - use POSIX termios whenever possible on Linux
1629 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
1630 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
1631 - login -h only for root (lmain.c)
1632 - login -r not needed for Linux (lmain.c)
1633 - sample login.defs modified for Linux (login.defs.linux)
1634 - swapped chfn USAGE and ADMUSAGE (chfn.c)
1635 - added -u to passwd usage (passwd.c)
1636 - no #! check necessary for Linux (shell.c)
1637 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
1638 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
1639 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
1640 can now be set in login.defs, old values are used as defaults (lmain.c)
1641 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
1642 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
1643 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
1644 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
1645 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
1646 - check for weak passwords too if previous password was empty (obscure.c)
1647 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
1648 - Linux has getusershell(), use it (chsh.c)
1649 - check if the new shell is executable by the user (chsh.c)
1650 - sleep before printing "Login incorrect", not the other way around (lmain.c)
1651 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
1652 - do "wheel group" more like BSD does (smain.c)
1653 - use getlogin() in su (smain.c)
1654 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
1655 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
1656 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
1657 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
1658 - LOGIN_STRING should work now (pwauth.c, getdef.c)
1659 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
1660 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
1661 not lost when you copy the right ones to Makefile and config.h
