3 shadow-4.1.0 -> shadow-4.1.1 UNRELEASED
7 * Do not install the shadow library per default.
9 * New option -l to avoid adding the user to the lastlog and faillog databases.
11 * Keep the access and modification time of files when moving an user's home
14 * su's arguments are now reordered. If needed, use -- to separate su's
15 options from the shell's options.
17 * Accept users specified as a numerical UID, or ranges of users (-user,
20 shadow-4.0.18.2 -> shadow-4.1.0 09-12-2008
24 When compiled with PAM support, it used the chpasswd policy file instead
25 of the chgpasswd policy file. If an administrator added some restriction
26 to the chgpasswd policy file, they were not taken into account.
29 - Add support for SHA256 and SHA512 encrypt methods (supported by new
31 - useradd: Allow non numerical group identifier to be specified with
33 - chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
34 - newgrp: Do not give an indication that the group has no password. Ask
35 for the password, as if there were a password.
36 - The permissions of the suid binaries is now configurable in
37 src/Makefile.am. Note that changing the permissions is not recommended.
38 - newgrp.c: Declare the child and pid variable at the beginning of a block.
39 This fixes a compilation issue with gcc 2.95.
40 - login_nopam: Add support for systems with no innetgr(). On those
41 systems, username with an @ will be treated like any other username
42 (i.e. lookup in the local database for an user with an @). Thanks to
43 Mike Frysinger for the patch.
44 - Add support for uClibc with no l64a().
45 - userdel, usermod: Fix infinite loop caused by erroneous group file
46 containing two entries with the same name. (The fix strategy differs
48 (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
49 - userdel: Abort if an error is detected while updating the passwd or group
50 databases. The passwd or group files will not be written.
51 - usermod: Update the group database before flushing the nscd caches.
52 - usermod: Make sure the group modifications will be allowed before
53 writing the passwd files.
54 - Flush the nscd tables using nscd -i instead of the private glibc socket.
55 - usermod: Make usermod options independent of the argument order.
56 - newgrp: Do not request a password when a user uses newgrp to switch to
58 - passwd: -l/-u options: edit the shadow account expiry field *in
59 addition* to editing the password field.
60 - pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
62 - su: Avoid terminating the PAM library in the forked child. This is done
63 later in the parent after closing the PAM session.
64 - userdel: Fix the homedir prefix checking.
65 - passwd, usermod: Refuse to unlock an account when it would result in a
67 - Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
68 getgrgid(), and getspnam(). There should be no functional changes.
69 - gpasswd: Only read information from the local file group database. It
70 writes the changes in /etc/group and/or /etc/gshadow, but used to read
71 information from getgrnam (hence possibly from another group database).
72 - New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
73 better support for split groups. Be careful when using this variable:
74 not all tools support well split groups (in or out of the shadow
75 tool suite). It fixes gpasswd and chgpasswd when split groups are used.
76 - Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
77 SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
79 - chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
80 -s/--sha-rounds to supersede the system default encryption algorithm.
81 - chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
82 will respect the system default configured in /etc/login.defs
85 - Generate the translated manpages from PO at build time.
86 - The generated manpages will change depending on the configure options.
87 If you use different options than the one used for the distributed
88 archive, you should re-generate the manpages.
89 - login.defs should now describe all the variables.
90 - The tools' documentation details the login.defs variables they use.

102 when one of the -, -l, or --login options is set, even if called by root.
103 - limits: Support for 2 new resource limits: max nice value, and max real

542 the rmdir() fails. Patch prepared by Timo Lindfors <lindi-spamtrap@newmail.com>.
543 http://bugs.debian.org/166369

610 Patch and comment by Koblinger Egmont <egmont@uhulinux.hu>:
611 Only two arguments are passed to the open() call though it expects three
612 because O_CREAT is present. Hence the permission of the file first becomes
613 some random garbage found on the stack, and an attacker can perhaps open
614 this file and hold it open for reading or writing before the proper
615 fchmod() is executed. (Actually, we could also pass the final "mode" to
616 the open() call and then save the consequent fchmod().)
617 - SELinux changes: added changes in chage, chfn, chsh, passwd for allow

823 is login string isn't longer than possible it will be good prepare using
824 probably _POSIX_LOGIN_NAME_MAX from <bits/posix1_lim.h>,
825 shadow-4.0.0-owl-chage-drop-priv.diff
826 shadow-4.0.0-owl-pam-auth.diff
827 Merge part with reorder initialize PAM and checkin is chage is runed by
828 root or not - now chage can be runed from non-root account for checking
829 by user own account information (if PAM enabled).
830 - fixes for handle/print correctly 32bit uid/gid (Thorsten Kukuk <kukuk@suse.de>),
831 - implemented functions for better reloading the nscd cache (per NSS map)
832 (Thorsten Kukuk <kukuk@suse.de>),
833 - fixed warnings "not used but defined" on compile using gcc 3.0.x
834 (bulletpr00ph <bullet@users.sourceforge.net>),
835 - added ja, ko translations found in SuSE,
836 - added symlinks: newgrp -> sg, vipw -> vigr,
837 - added vigr(1) man page as roff .so link to vipw(1),
838 - added sg(1) man page as roff .so link to newgrp(1),
839 - installed fix for SEGV when using pwck -s on /etc/passwd file with
842 shadow-20001016 => shadow-4.0.0 06-01-2002
844 - fix bug discovered and fixed by Marcel Ritter
845 <Marcel.Ritter@rrze.uni-erlangen.de>
846 Due to a big buffer size in lib/commonio.c this error does only appear
847 if a line gets longer than 4096 bytes (there are probably very few people
848 stumbling across this).
849 Ths bug can be exposed by trashing /etc/groups file using useradd with script:
854 while [ $NUM -le 1000 ]; do
855 useradd -g demogroup -G demogroup -p "NONE" user$NUM
858 - remove limit 32 to groups per user by (the same user can belong to
859 more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
860 NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
861 NOTE: it probably need testing on other system for add
862 some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
863 - added -s option to {pw,grp}ck to sort checked files by UID/GID,
864 - drop detecting is pam_strerror() need one or two arguments. Instead using
865 PAM_STRERROR() macro use directly pam_strerror() function with two
866 arguments. pam_strerror() with one argument is obsoleted,
867 - adde ja man pages (probably some man pages need update),
868 - much better automake support,
869 - added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
870 groupmod(8), shadow(5) (man pages for other nations also are welcome),
871 - mamny small fixes and updates nad improvements in man pages,
872 - aplayed Debian patch to man pages for shadowconfig,
873 - remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
876 shadow-20001012 -> shadow-20001016:
877 - conditionaly disabled body reload_nscd() because not every
878 version of nscd can handle it (this can be enabled by define
879 ENABLE_NSCD_SIGHUP) (Marek Michałkiewicz <marekm@linux.org.pl>)
880 - fixes on autoconf/automake level for dist target,
881 - Julianne F. Haugh new contact adress.
883 shadow-20000902 => shadow-20001012
885 - removed /redhat directory with obsoleted files (partialy rewrited spec
886 file is now in root directory),
887 - aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
888 overwrite previously existing groups in adduser,
889 - added PAM support for chage (bind to "chage" PAM config file) also
890 added PAM support for all other small tools like chpasswd, groupadd,
891 groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common
892 "shadow" PAM config file) - this modificaytions mainly based on
893 modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
894 - many small fixes and improvments in automake (mow "make dist"
896 - added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).
898 shadow-20000826 => shadow-20000902
900 This is probably the last release from me.
901 Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
904 (I'm still interested to know what is going on with this package,
905 which is fairly important to many Linux distributions, so please
906 Cc: marekm@linux.org.pl in any related discussions - just don't
907 expect me to respond quickly...)
909 Previous warning still applies - be careful!
911 - applied some of the Red Hat patches (revised slightly), thanks to
912 Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
913 lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
914 in glibc 2.1.x) after changing anything, add usermod -L and -U
915 options, remove LOG_CONS from openlog(), chage -d and -E handles
916 dates in yyyy-mm-dd format ('/' is not required)
919 shadow-19990827 => shadow-20000826
921 WARNING: this release is not tested (other than that it compiles for me),
922 please be careful. Previous release was a year ago, so it is really time
923 to release something and start looking for a new, better maintainer...
924 (I've been extremely busy recently. Credit for most of the real work,
925 such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
926 who maintains this package for Debian.)
928 - merged most of the changes from Debian (not all of them yet, PAM support
929 should be complete but is not tested - need to upgrade to potato first)
930 - added Polish translations of manual pages from PLD
931 - change sulog() to not depend on global variables oldname, name
932 - try to not follow symbolic links when deleting files recursively
933 in userdel (still not perfect, safest to do it in single user mode)
934 - removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
935 (a few ANSI C constructs were used already, and no one complained)
936 - updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)
938 shadow-19990709 => shadow-19990827
940 - upgrade to autoconf-2.13, automake-1.4, libtool-1.3.3

942 - i18n: added Swedish translation by Kristoffer Brånemyr <ztion@swipnet.se>
943 - logoutd no longer reads /etc/logoutd.mesg at startup - instead, read
944 it when sending to luser's tty (no need to reload with SIGHUP)
945 - added support for "usergroups" feature often found in Linux distributions
946 (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
947 username == groupname, then set umask to 002 instead of 022)
948 - Debian: pwck and grpck are now run from a daily cron job (root will
949 receive an e-mail if something is wrong), and at system startup
950 - added support for setting umask in /etc/limits
951 - when using OPIE, re-prompt with echo on after empty password was entered
952 - GETPASS_ASTERISKS now run time configurable (login.defs)
953 - getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
954 - getpass() allows all input to be erased using Control-U, and beeps when
955 too many characters are entered
956 - removed obsolete sgtty support, in 1999 everyone should have termios :)
957 - Debian: tar wrapper no longer needed to build packages as non-root user
958 (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
959 - Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
960 dpkg-architecture, cross compilation, only build passwd, add
961 etc/login.defs.hurd conffile, conditionalize CBAUD
962 - newgrp sets $HOME before running the new shell
963 - both "sg group command" (usage message) and "sg group -c command"
964 (man page) work, updated both the usage message and the man page :)
965 - i18n: added missing _() for some translatable strings
967 shadow-19990607 => shadow-19990709
969 - added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
970 - fixed a bug in newgrp if the user is in >= 17 groups
971 - added @LIBSKEY@ to LDADD for all programs (for some reason,
972 almost all programs need it if skey/opie support is enabled)
973 - changed grpconv/grpunconv to compile with --disable-shadowgrp
974 - changed faillog to do something (assume -p) with no options specified
975 - updated version of the udbachk passwd/shadow/group file integrity
976 checker (contrib/udbachk.v012.tgz)
978 shadow-19990307 => shadow-19990607
980 - upgraded to libtool-1.2, latest config.{guess,sub}
981 - added missing #include "defines.h" in libmisc/login_desrpc.c - thanks
982 to almost everyone for reporting it :-)
983 - moved PAM-related defines to pam_defs.h
984 - added some braces to if/else to avoid egcs warnings
985 - started adding PAM support to login (based on util-linux, not finished yet)
986 - changed "!" to "x" for pw_passwd in src/newusers.c
987 - a few more Y2K fixes
988 - added contrib/udbachk.tgz (passwd/shadow/group file integrity checker),
989 thanks to Sami Kerola
990 - Debian: made /etc/{limits,login.access,login.defs,porttime,securetty}
991 files all mode 0600 (Bug#38729 - login: /etc/limits is world readable)
992 - updated mailing list information (moved again, now hosted by SuSE),
993 updated README.mirrors, other minor documentation updates
994 - made getpass work with redirected stdin
995 - new readpass echoing asterisks disabled by default by popular demand
996 (can be enabled at compile time: ./configure --enable-readpass)
997 - the random number of asterisks in readpass is now more random
998 (random number generator initialization was missing)
999 - commented out --enable-md5crypt (obsolete) in configure.in
1000 - when checking for libskey, link with -lcrypt if libcrypt is available
1001 (otherwise the configure test for libskey fails - libskey needs libcrypt)
1002 - added Package/Version ident strings (so you can use the RCS "ident"
1003 command to check any binary, which version of shadow it comes from)
1005 shadow-981228 => shadow-19990307
1007 - added support for setting process priority in /etc/limits
1008 - i18n: updated Greek translation
1009 - i18n: added Polish translation by Arkadiusz Miskiewicz
1010 - documented the -p option in useradd.8 and usermod.8 man pages

1013 - added restart/reload/force-reload to /etc/init.d/logoutd (found by lintian)
1014 - always require password for root logins (even with NO_PASSWORD_CONSOLE)
1015 - workaround for RedHat's CREATE_HOME feature in /etc/login.defs
1016 - changed to Y2K compatible version numbering
1017 - more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
1018 values of user-entered dates (you can still enter dates in any format
1019 supported by GNU date)
1020 - oops, added doc/README.nls to list of files to distribute
1021 - added missing sanitize_env() call to src/login.c
1022 - debian/rules installs /bin/login non-setuid by default, just in case...
1023 - build Debian packages with cracklib support (depends on cracklib-runtime)
1025 shadow-980724 => shadow-981228
1027 - login now clears the username in argv[] (in case someone types the
1028 password instead of username, by mistake)
1029 - i18n support, Greek translation (Nikos Mavroyanopoulos), see README.nls
1030 - updated author's e-mail address (jfh@tab.com -> jfh@bga.com)
1031 - new getpass() replacement that displays *'s (Pavel Machek)
1032 - no password required when logging in from ttys listed under
1033 NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
1034 - fixed limits code so RLIMIT_AS should work
1035 - upgraded to Debian 2.0
1036 - built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
1037 in reasonable time again
1038 - upgraded to automake-1.3, libtool-1.0h (also new config.guess and
1039 config.sub that work on i686)
1040 - usermod fixed to handle group names starting with digits (not recommended)
1042 shadow-980626 => shadow-980724
1044 - security: login no longer gives you a root shell if setgid()
1045 or initgroups() or setuid() fails for any reason, discovered
1046 by Ted Hickman <thickman@sy.net>
1047 - remove libshadow.so -> libshadow.so.x.x symlink after install
1048 - a few int -> uid_t type cleanups
1049 - fail immediately (don't retry) in *_lock() if euid != 0
1050 - added sample PAM config files etc/pam.d/{passwd,su}
1051 - preliminary PAM support in su (untested - use at your own risk,
1052 comments and patches welcome!)
1053 - cleanup and more comments in OPIE code (Algis Rudys)
1054 - added support for TCFS (Transparent Cryptographic File System)
1055 (use ./configure --with-libtcfs, see http://tcfs.dia.unisa.it/
1056 for more info), thanks to Aniello Del Sorbo
1058 shadow-980529 => shadow-980626
1060 - fixed bug in commonio_lock() (infinite recursion if lckpwdf() not
1061 used and database cannot be locked), thanks to Jonathan Hankins
1062 - fixed bug in copy_tree() (NUL-terminate readlink() results),
1063 thanks to Lutz Schwalowsky
1064 - no need to press Enter after Ctrl-C to interrupt password prompt
1065 - removed a few harmless gcc warnings
1066 - secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)
1067 - faillog.8: changed /usr/adm -> /var/log
1068 - pwconv.8: documented that it may fail on invalid password files
1070 shadow-980417 => shadow-980529
1072 - fixed "interesting" strzero() bug introduced by me in 980417:
1073 strzero(cp) didn't work as intended (the macro used a local
1074 variable called "cp" - oops...); Leonard N. Zubkoff was the
1075 first person to report it - thanks!
1076 - fixed usermod -e to accept empty argument (like useradd),
1077 thanks to Martin Bene
1078 - several changes from Debian 980403-0.2, see debian/changelog
1079 - added contrib/shadow-anonftp.patch (not yet merged, sorry...)
1080 thanks to Calle Karlsson
1082 shadow-980403 => shadow-980417
1084 - fixed login session limits (again - broken since 980130)
1085 - more symbolic constants for exit status values
1086 - fixed logoutd to work with 8-character usernames in utmp
1087 (no room for terminating NUL!)
1088 - various fixes to make the code more glibc2-friendly
1089 - updated doc/cracklib26.diff (fix for empty gecos, etc.)
1090 - updated the files in redhat/ from shadow-utils-970616-11.src.rpm
1093 shadow-980130 => shadow-980403
1095 - security: su now creates the sulog file (if enabled and doesn't
1096 already exist) with umask 077
1097 - hopefully removed arbitrary group size limits (not yet for
1098 shadow groups though - sgetsgent() still needs a rewrite,
1099 but I don't want to delay this release any longer...)
1100 - fixed NULL dereference in groupmod -n
1102 shadow-971215 => shadow-980130
1104 - Debian binary packages can be built without root privileges
1105 (tar wrapper - debian/tar.c)
1106 - new subdir "redhat" (needs more work, see redhat/README)
1107 - in several places, exit(127) if exec fails with ENOENT, and
1108 exit(126) on other errors (as in ksh and bash)
1109 - renamed getpass() and md5_crypt() to libshadow_* to avoid name
1110 conflicts with libc functions - md5_crypt() is also in libcrypt.a
1111 on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
1112 - handle crypt() returning NULL (possible according to Single Unix
1113 Spec) more gracefully (exit instead of SIGSEGV)
1114 - fixed bug in putgrent() that showed up when realloc() moved the
1115 buffer while expanding it, thanks to Floody <flood@evcom.net>
1116 - fixed bug in login session limits (with a limit set to N logins,
1117 only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
1118 - upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
1119 - newer config.guess and config.sub (should work on x86 for x > 5)
1120 - removed doc/automake-1.0.diff (obsoleted by automake-1.2)
1121 - added doc/cracklib26.diff (some patches for cracklib-2.6)
1122 - documented more (not all yet) login.defs(5) settings
1123 - replaced more exit status numeric values with #defines
1124 - shadow-utils.spec now generated from shadow-utils.spec.in
1125 (so I don't have to edit version numbers for every new release)
1126 - groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
1127 ("force" - exit(0) if the group already exists); other RedHat-
1128 specific options not added yet (best done in a perl script that
1129 runs useradd/usermod/groupadd - see Debian's adduser-3.x)
1130 - added -O option (override login.defs values) to useradd and groupadd
1131 - if usermod can't update the group file(s), exit(10) but update the
1132 password file(s) anyway (as documented by Solaris man page)
1133 - useradd should no longer set sp_expire to the current date (oops)
1134 - configure.in: added --enable-desrpc, check for gethostbyname in libc
1135 before trying libnsl (necessary for Solaris; not for Linux or Irix,
1136 even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
1137 detection, setpgrp vs. setpgid, other minor tweaks
1138 - various */Makefile.am tweaks
1139 - login.defs: added FAKE_SHELL - program to run instead of the login
1140 shell, with the real shell in argv[0] (Frank Denis)
1141 - login.defs: ignore case in yes/no settings
1142 - more E_* defines instead of hardcoded numbers for exit()
1143 - added sanitize_env() for setuid programs
1144 - login_desrpc() checks for getnetname() errors
1145 - new password is not "too similar" if it is long enough
1146 - replacement strstr() was static, no one noticed :-)
1147 - {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
1148 lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
1149 - login sets $REMOTEHOST for remote logins
1150 - added newgrp -l option (Single Unix Spec, same as "-")
1151 - EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
1152 200K of disk space on Linux/x86), enabled by default if supported by
1153 the system, use ./configure --disable-shared if it causes any problems.
1154 Warning: libshadow.so is intended for internal use by this package
1155 only - binary compatibility with future releases is not guaranteed.
1156 There should be no need to link any other programs with libshadow.so -
1157 the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
1158 - pam_strerror() takes one or two arguments, depending on the Linux-PAM
1159 version (!) - added check to configure; fixed do_pam_passwd prototype
1160 - libmisc/login_access.c should compile on Linux/PPC and Solaris
1161 - added information about the new ftp site to doc/README.mirrors
1163 shadow-971001 => shadow-971215
1165 - added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
1166 - updated the RPM .spec file
1167 - renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
1168 (glibc defines something else named "rlogin" in utmpbits.h ?)
1169 - added MD5 checksums in Debian packages
1170 - added -p and -g options to vipw (edit the password or group file
1171 respectively, regardless of the command name in argv[0])
1172 - removed old DBM support (NDBM code is still there)
1173 - fixed a bug in gpasswd: current username was incorrectly identified as
1174 "root" because of setuid(0) done too early. It may be a security hole
1175 when using shadow groups - if "root" is listed as a group administrator,
1176 any user can add/remove members in that group. Thanks to Jesse Thilo.
1177 - gpasswd now logs which user (root or group admin) made the changes
1178 - passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
1179 - newgrp and add_groups() allocate supplementary group lists dynamically
1180 - moved check_shell() from src/chsh.c to libmisc/chkshell.c
1181 - CHFN_RESTRICT in login.defs can now specify exactly which fields may be
1182 changed by regular users (any combination of letters "frwh")
1183 - fixed contrib/pwdauth.c segfault with non-existent usernames
1184 - minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
1185 - new date parsing code (from GNU date) used by useradd, usermod, chage
1186 - upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
1187 - converted code to ANSI C, added ansi2knr (untested - use gcc!)
1188 - fixed useradd -G segfault (one '*' that shouldn't be there)
1189 - allow 8-bit characters in chfn
1190 - added support for RLIMIT_AS (max address space) in libmisc/limits.c
1191 - changed the handling of NIS plus entries in password files
1192 - some more tweaking in various debian/* files
1193 - logoutd uses getutent() instead of reading utmp file directly
1194 - fixed lckpwdf() called twice (and failing) when changing password
1195 if the user is not listed in /etc/shadow (Mike Pakovic)
1196 - erase and kill characters left unchanged if not defined in login.defs
1198 shadow-970616 => shadow-971001
1200 - Debian: mkpasswd no longer installed (dbm files not supported)
1201 - chpasswd checks for shadow/non-shadow at run time, too
1202 - added chpasswd -e (input file with encrypted passwords) - Jay Soffian
1203 - changed libmisc/login_access.c as suggested by Dave Hagewood
1204 - replaced sprintf() with snprintf() in several places
1205 - added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
1206 - minor tweaks in contrib/adduser.c (/usr/local -> /usr)
1207 - non-root users can only run su with a terminal on stdin
1208 - temporarily disabled DES_RPC because getsecretkey() causes login to hang
1209 for 5 minutes on at least one RH 4.0 system. Not sure if this is a bug
1210 in libc, or system misconfiguration. Needs further investigation.
1211 - check for strerror() and -lrpcsvc (should compile on SunOS again)
1212 - fixed free() called twice in libmisc/mail.c
1213 - added information about mirror sites (doc/README.mirrors)
1214 - updated pwconv.8 and pwunconv.8 man pages
1215 - "make install" now installs pwconv, pwunconv, grpconv, grpunconv
1216 - pwauth.8 no longer installed (AUTH_METHODS not supported by default)
1217 - corrected su.1 man page ($SHELL not used)
1218 - no need for --with-md5crypt if the MD5-based crypt() is already in libc
1219 (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
1220 - cleaned up PASS_MAX in getpass() (127 always assumed)
1221 - default editor for vipw changed from /bin/ae to a real editor :)
1223 shadow-970601 => shadow-970616
1225 - fixed execlp call (missing NULL) in src/vipw.c
1226 - vipw now preserves permissions on edited files
1227 - commented out the xdm-shadow hack in shadowconfig
1228 - improved RedHat spec file (Timo Karjalainen)
1229 - updated mailing list information
1230 - added information about the shadow paper (doc/README.shadow-paper)
1231 - renamed doc/console.c.spec (confused RPM)
1233 shadow-970502-2 => shadow-970601
1235 - fixed a typo in libmisc/mail.c causing login to segfault
1236 if MAIL_CHECK_ENAB=yes (sorry!)
1237 - patches for OPIE support (Algis Rudys) (untested)
1238 - programs that modify /etc/passwd or /etc/shadow will use
1239 lckpwdf() if available
1240 - now compiles with PAM support! (still untested)
1241 - cosmetic error message changes (prefixed by argv[0]:)
1243 shadow-970216 => shadow-970502-2
1245 - shadow group support fixes (grpconv didn't work - for some
1246 reason, putsgent() returns 1 instead of 0 on success;
1247 now -1 = failure, anything else = success)
1248 - upgraded to autoconf-2.12
1249 - pwconv and pwunconv now follow other UN*X systems and SVID3
1250 (modify files in place), original versions moved to "old"
1251 - scologin.c moved to "old" (it was only for SCO Xenix) so
1252 people stop sending patches for scologin.c gcc warnings :)
1253 - don't use the MD5* functions in libmisc/salt.c (glibc has
1254 the new md5 crypt(), but no <md5.h> and MD5* functions!)
1255 - support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
1256 - "passwd -S -a" now really works
1257 - support for Debian, vipw, a few fixes (Guy Maor)
1258 - src/login.c radius bug fix (Rafal Maszkowski)
1259 - ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
1260 - fixes for glibc and DES_RPC (Thorsten Kukuk)
1261 - limits.5 man page (Luca Berra)
1262 - expiry will work setgid shadow too, removed euid 0 check
1263 - added check for a64l() to configure (glibc)
1265 shadow-961025 => shadow-970216
1267 - major rewrite of *io.c (no more 4 copies of almost identical code)
1268 - use fsync() (if available) instead of sync() when updating password files
1269 - use fchmod() and fchown() if available
1270 - keep the NIS "plus on a line by itself" entries at end of passwd/group
1271 - configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
1272 - passwd -S -a: list information about all users (root only)
1273 - passwd -k: change only expired passwords
1274 - passwd -q: quiet mode
1275 - first attempt at PAM support in passwd
1276 - passwd updates the non-shadow password if /etc/shadow exists but the
1277 user has no shadow password
1278 - passwd logs who changed the password, added hook to allow non-root
1279 administrators who can change passwords (not implemented yet)
1280 - su sets $HOME even without the "-" option (suggested by Joey Hess)
1281 - added -p (set encrypted password) option to useradd and usermod
1282 (idea from hpux10 - undocumented option used internally by SAM)
1283 - useradd -D -e does the right thing (set default expiration date)
1284 - USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
1285 because there are just too many systems that need different commands
1286 - removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
1287 faillog file format has been changed (somewhere between 960129 and
1288 960810), please truncate the old file (if any) to zero length
1289 - ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
1290 - wtmp, lastlog, faillog file location guessed by configure
1291 - separate checks for invalid user and group names, max username length
1292 based on struct utmp (it's not always 8 characters)
1293 - pwck and grpck now check for invalid user/group names
1294 - pwck -q (quiet, report only serious problems) option added
1295 - separate cleaner sgetpwent() without the NIS magic
1296 - NIS entries ignored (never changed) by *io.c, pwck, grpck
1297 - various code cleanups
1298 - new get_my_pwent() function for getting my own username, uid etc.
1299 - faillog opens the file read-write if possible (even if not root)
1300 - passwd -S allowed for normal users (for their own uid only)
1301 - handle the case of login denied to passwordless accounts better
1302 ("Login incorrect" without "Password:" prompt looks strange)
1303 - corrected author information and removed a copyright restriction
1305 shadow-960925 => shadow-961025
1307 - fixed a few typos in shadow group code
1308 - don't check for names starting with 'r' to determine if the shell
1309 is restricted, use /etc/shells instead (for the "rc" shell)
1310 - removed extra definition of LASTLOG_FILE in configure.in
1311 - expiry no longer segfaults if no /etc/shadow
1312 - userdel -r "can't remove mailbox" warning no longer printed on success
1313 - useradd exit codes changed to match hpux10 man page
1314 - fixed possible fd leak etc. in file locking code (lib/commonio.c)
1316 shadow-960920 => shadow-960925
1318 - bug fixes to the new environment code using malloc
1319 - use hardcoded names instead of basename(argv[0]) for openlog() in programs
1320 that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
1321 - small fix to isexpired(), and use it in passwd as well
1322 - use strftime() and strptime() if available
1323 - added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
1324 contain encrypted passwords!)
1325 - pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
1326 (nothing bad happened yet, just a cleanup)
1327 - gpasswd should work with both shadow and non-shadow group passwords
1328 - detect unsupported options if no shadow (gpasswd, useradd, usermod)
1329 - passwd -e for sunos4 (ATT_AGE), untested
1330 - read environment from file (ENVIRON_FILE in login.defs), idea from ssh
1331 - small fix to l64a()
1332 - passwd prints a message after password successfully changed (for things
1333 like poppassd which run passwd and expect some output)
1334 - passwd logs if password was changed by root (as opposed to a luser)
1335 - passwd uses current uid if no username argument and getlogin() fails
1337 shadow-960910 => shadow-960920
1339 - use malloc for environment variables, no more MAXENV (Juergen Heinzl)
1340 - newusers should work with both shadow and non-shadow passwords
1341 (still left to do: chpasswd, gpasswd)
1342 - login-static no longer compiled by default
1343 - more SYSLOG() macros
1345 shadow-960810 => shadow-960910
1347 - updated README.linux to point to the new ftp site
1348 - chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
1349 - man pages now closer to LDP standards (Ivan Nejgebauer)
1350 - newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
1351 - obscure.c fixed to compile with HAVE_LIBCRACK
1352 - cosmetic message changes in age.c
1353 - utmp open error check fixed in utmp.c
1354 - grpunconv added (Michael Meskes)
1355 - login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
1356 - logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
1357 - sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
1358 - passwords can be changed if sp_max == -1 (now considered infinity)
1359 - usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
1360 - started replacing lots of #ifdef USE_SYSLOG with cleaner macros
1361 - contrib/rpasswd.c added (Joshua Cowan)
1362 - PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
1363 - workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
1364 doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).
1366 shadow-960129 => shadow-960810
1368 - automake, configure checks for libcrypt and libcrack (Janos Farkas)
1369 - added --enable-shadowgrp to configure (shadow groups disabled by default)
1370 - should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
1371 - login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
1372 - hopefully removed all the rcsid warnings
1373 - contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
1374 - resource limits (Cristian Gafton)
1375 - workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
1376 - more fixes in man pages
1377 - pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
1378 - most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
1379 su, useradd, userdel, usermod) should now work with both shadow and
1380 non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
1381 run time); a few programs still left to do
1382 - mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
1383 - new contrib/adduser.c from Chris Evans
1384 - lots of other minor changes
1385 - source tree reorganization, GNU autoconf, portability cleanups
1386 - basename() renamed to Basename() to avoid name space confusion
1387 - new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
1388 - newgrp cleanup and a few fixes
1389 - useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
1390 - don't make the first group member the group admin by default
1391 (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
1392 - password aging constants, NGROUPS_MAX and syslog stuff in only one
1393 place (defines.h) instead of repeating it in all source files...
1394 - added userdel -r safety check (refuse to remove the home directory
1395 if it would result in removing some other user's home directory)
1396 - usermod -u now correctly checks for non-unique uid (unless -o)
1397 - sync() after updating password files, just to be more safe
1398 - "make install" should install /etc/login.defs if it doesn't exist
1399 - new option to control what happens if we can't cd to the home directory
1400 (DEFAULT_HOME in /etc/login.defs)
1401 - enter the home directory as the user, not as root (for NFS etc.)
1402 - added check for Slackware bugs (nobody UID -1) in pwck and grpck
1403 - new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
1404 possible to add specified groups (floppy etc.) for console logins
1405 - new faillog feature: lock account for specified (per-user) time since
1406 the last failure after exceeding the failure limit
1407 - new man pages (gpasswd.1, login.access.5, suauth.5)
1408 - fixes in man pages, renamed *.4 to *.5
1409 - new "contrib" directory (two adduser programs)
1410 - changed some "system" to "feature" #ifdefs (autoconf someday...)
1411 - sulogin no longer requires to be run from init, should work from rc
1413 - changes to prevent unshadowing with libc SHADOW_COMPAT (get info
1414 using xx_locate(), modify it and call xx_update(), don't write back
1415 anything returned by getpwnam() etc.)
1416 - stupid bug fixed in lastlog.c
1417 - don't move non-directories in "usermod -m"
1418 - don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
1419 - macros to get around ancient compilers which don't like prototypes
1420 - make more use of "const" (not everywhere yet)
1421 - added #ifdef AUTH_METHODS - very few people use administrator defined
1422 authentication methods because many programs are not aware of them;
1423 not supporting them makes the code simpler
1424 - new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
1425 - sgetgrent() in libshadow.a is optional, some versions of libc have it,
1426 see HAVE_SGETGRENT in config.h (grent.c)
1427 - don't use continued lines in /etc/group, the standard getgr*() functions
1428 don't support that (grent.c)
1429 - removed the third main() argument (according to libc docs, not allowed by
1430 POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
1431 - login access control (lmain.c, login_access.c)
1432 - added copyright notice to login_access.c (from logdaemon-5.0)
1433 - detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
1434 - added closelog() in su before executing the shell (smain.c)
1435 - getting current user name changed (smain.c)
1436 - "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
1437 - getpass() shouldn't return NULL except on errors (getpass.c)
1438 - moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
1439 - SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
1440 - can use shadow support in new versions of Linux libc instead of libshadow.a,
1441 see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
1442 - "no shadow password" not logged, the same /bin/login should work with both
1443 shadow and non-shadow passwords (lmain.c)
1444 - some cleanup in various places (lmain.c, passwd.c)
1445 - new program to verify username/password pairs, for xlock etc.; it is not
1446 installed by default, read the comments first (pwdauth.c)
1447 - authentication programs run with empty environment for safety (pwauth.c)
1448 - added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
1449 - common code separated from *io.c (commonio.c)
1450 - ownership and permissions on password files are now preserved (we may try
1451 to make more use of setgid and setuid non-root programs in the future)
1452 - added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
1453 MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
1454 - termios/termio/sgtty macros cleaned up a bit
1456 shadow-951218 => shadow-960129
1458 Emergency bug fix release - no new features since 951218. There are many
1459 new changes, but this bug really can't wait until they are tested.
1461 Probably all previous versions of the shadow suite have a serious bug which
1462 makes it possible to overwrite the stack by entering very long username at
1463 the login prompt. This can give root access to any remote user!
1465 Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
1466 size of the array in lmain.c). Aaargh!!!
1468 shadow-951203 => shadow-951218
1471 - Linux utmp handling fixes (utmp.c)
1472 - last failure date printing fixes (failure.c)
1473 - minor fix to compile with USE_CRACKLIB (obscure.c)
1474 - eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
1475 - basename.c added, replacing duplicated code in various places
1476 - "su -" runs the shell with '-' in argv[0] again (smain.c)
1477 - removing at/cron jobs cleaned up (userdel.c)
1478 - /etc/gshadow should not be world-readable (sgroupio.c)
1479 - if fflush() failed, files were not closed (*io.c)
1480 - login prompt is now "hostname login: " on Linux (lmain.c, login.c)
1481 - "save" and "restore" targets commented out (don't work) (Makefile.linux)
1482 - some minor cleanups for gcc -Wall (unused variables etc.)
1483 - removed README.FIRST (copyrights are OK now)
1484 - updated ANNOUNCE, README.linux, WISHLIST
1485 - as suggested, converted to RCS
1487 shadow-3.3.2-951127 => shadow-951203-jfh
1490 - Added the BSD-style copyright to all of the files. Any files with the
1491 old copyright have multiple copyright holders and need to be cleanroomed
1492 to produce BSD-style copyrightable files, or I need to get the consent
1493 of the others to change the copyright.
1494 - Changed the ANNOUNCE file to not refer to the README.FIRST file. Now
1495 that all of the files should have the correct copyright there is no need
1496 to refer to that e-mail message.
1497 - Changes SCCS strings to "%W% %U% %G%". Marek needs to either convert to
1498 RCS or check into SCCS and then checkout. I'd suggest using RCS ;-)
1500 jfh@rpp386.cactus.org
1502 shadow-3.3.2-951106 => shadow-951127
1504 Note: for now this code only supports Linux. All the #ifdef's are there
1505 (and will be; support for at least SunOS 4.1.x would be nice) but:
1506 - I had to fix some potential security problems resulting from sloppy
1507 coding (no bounds checking), and it was easier for me to use snprintf()
1508 (not available on many systems, unfortunately), I'll fix that later.
1509 Old versions of Linux libc don't have snprintf() either, and the one
1510 in libbsd.a ignores the max size - don't use it! (libc-4.6.27 is OK)
1511 - I am lazy and only updated Makefile.linux and config.h.linux this time
1512 - I don't have root access to non-Linux systems (this means no testing)
1513 - this code needs some major reorganization, which will (hopefully)
1517 - some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
1518 - login can be statically linked (not that I think it's a good idea, better
1519 fix the telnetd, but paranoid people will like it :-)
1520 - login is installed non-setuid by default
1521 - check for NULL from getpass()
1522 - wipe cleartext password from getpass() when no longer needed (pwauth.c)
1523 - use standard "Password: " prompt by default (pwauth.c)
1524 - hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
1525 - oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
1526 - Linux has <lastlog.h>
1527 - print ll_host on Linux too (lmain.c)
1528 - size checking in various places (setuid root programs, argh!)
1529 - preserve TERM from getty (lmain.c)
1530 - don't ignore SIGHUP (lmain.c)
1531 - :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
1532 - remove LD_xxx (env.c)
1533 - use bzero() instead of memset() for BSD portability and less #ifdef's
1534 (if the system has no bzero(), implement it as a macro using memset())
1535 - the above fixes wrong order of memset() parameters (log.c)
1536 - use getutent/pututline instead of doing it by hand (utmp.c)
1537 - added the new settings to login.defs.linux
1538 - added login_access.c to the distribution (not used yet)
1542 shadow-3.3.2 => shadow-3.3.2-951106
1544 - added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
1545 - malloc/strdup error checking, hopefully no more core dumps...
1546 - define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
1547 - changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
1548 - larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
1549 - use POSIX termios whenever possible on Linux
1550 - list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
1551 - strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
1552 - login -h only for root (lmain.c)
1553 - login -r not needed for Linux (lmain.c)
1554 - sample login.defs modified for Linux (login.defs.linux)
1555 - swapped chfn USAGE and ADMUSAGE (chfn.c)
1556 - added -u to passwd usage (passwd.c)
1557 - no #! check necessary for Linux (shell.c)
1558 - define OLD_CRON for some old incompatible Linux distributions (userdel.c)
1559 - PASS_MAX is now 127 (not 8) for Linux (getpass.c)
1560 - LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
1561 can now be set in login.defs, old values are used as defaults (lmain.c)
1562 - unique uid/gid selection now more robust (useradd.c, groupadd.c)
1563 - UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
1564 - CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
1565 - PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
1566 - PASS_MAX_LEN, check truncated passwords again (obscure.c)
1567 - check for weak passwords too if previous password was empty (obscure.c)
1568 - CHFN_RESTRICT: don't let users change their full names (chfn.c)
1569 - Linux has getusershell(), use it (chsh.c)
1570 - check if the new shell is executable by the user (chsh.c)
1571 - sleep before printing "Login incorrect", not the other way around (lmain.c)
1572 - don't be picky about utmp only if any of -rfh flags given (lmain.c)
1573 - do "wheel group" more like BSD does (smain.c)
1574 - use getlogin() in su (smain.c)
1575 - UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
1576 - #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
1577 - Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
1578 - ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
1579 - LOGIN_STRING should work now (pwauth.c, getdef.c)
1580 - kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
1581 - mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
1582 not lost when you copy the right ones to Makefile and config.h
