shadow-4.1.2.1 -> shadow-4.1.3						UNRELEASED

*** general:
- packaging
  * Added support for OpenPAM.
  * Added support for uclibc.

  * Added support for long options --add (-a), --delete (-d),
    --remove-password (-r), --restrict (-R), --administrators (-A), and
    --members (-M).
- groupadd
  * audit logging improvements.
- groupdel
  * audit logging improvements.
- groupmems
  * Check if user exist before they are added to groups.
  * Avoid segfault in case the specified group does not exist in /etc/group.
  * Everybody is allowed to list the users of a group.
  * /etc/group is open readonly when one just wants to list the users of a
    group.
  * Added syslog support.
  * Use the groupmems PAM service name instead of groupmod.
  * Fix segmentation faults when adding or removing users from a group.
  * Added support for shadow groups.

    --list (-l), --group (-g).
- newusers
  * Implement the -r, --system option.
- passwd
  * For compatibility with other passwd version, the --lock an --unlock
    options do not lock or unlock the user account anymore.  They only
    lock or unlock the user's password.
- useradd
  * audit logging improvements.
- userdel
  * audit logging improvements.
- usermod
  * Allow adding LDAP users (or any user not present in the local passwd
    file) to local groups

shadow-4.1.2 -> shadow-4.1.2.1						26-06-2008

*** security
- Fix an "audit log injection" vulnerability in login.
  This vulnerability makes it easier for attackers to hide activities by
  modifying portions of log events, e.g. by appending an addr= statement
  to the login name.

shadow-4.1.1 -> shadow-4.1.2						25-05-2008

*** security:
- generation of SHA encrypted passwords (chpasswd, gpasswd, newusers,
  chgpasswd; and also passwd if configured without PAM support).
  The number of rounds and number of salt bytes was fixed to their lower
  allowed values (resp. configurable and 8), hence voiding some of the
  advantages of this encryption method. Dictionary attacks with
  precomputed tables were easier than expected, but still harder than with
  the MD5 (or DES) methods.

*** general:
- packaging
  * Distribute the chfn, chsh, and userdel PAM configuration file.
  * Fix the detection of the audit, pam, and selinux library and header
    file; and fail if the feature is requested but not present on the
    system.
  * Fix build failure when configured with audit support.
- chfn
  * Allow non-US-ASCII characters in the GECOS fields ("name", "room
    number", and "other info" fields).
- login
  * Do not fail if a shell option, specified after --, has more than 2
    letters.
- su
  * If the SULOG_FILE does not exist when an su session is logged, make
    sure the file is created with group root, instead of using the group
    of the caller.
- vipw
  * Resume properly after ^Z.

*** documentation:
- Document the -r, --system option in the useradd, groupadd, and newusers
  manpages.
- Document the -c, --crypt-method and -s, --sha-rounds options in the
  newusers manpage.
- Document the -k, --skel option in the useradd manpage.
- Tag the section which require --enable-shadowgrp or --with-sha-crypt
  accordingly.

shadow-4.1.0 -> shadow-4.1.1						02-04-2008

*** general:
- security
  * Do not seed the random number generator each time, and use the time in
    microseconds to avoid having the same salt for different passwords
    generated in the same second.
- packaging
  * Do not install the shadow library per default.
- general
  * Do not translate the messages sent to syslog. This avoids logging
    PAM error messages in the users's locale.
- etc/login.defs
  * Set GID_MIN to the same value as UID_MIN by default (1000).
  * Added variables SYS_UID_MIN (100), SYS_UID_MAX (999), SYS_GID_MIN (100),
    SYS_GID_MAX (999) for system accounts.
- etc/useradd
  * /etc/default/useradd now defines HOME as /home to match FHS.
- chage
  * Fix bug which forbid to set the aging information of an account with a
    passwd entry, but no shadow entry.
- faillog
  * faillog -r now only reset the entries of existing users. This makes
    faillog faster.
- gpasswd
  * Fix failures when the gshadow file is not present.
  * When a password is moved to the gshadow file, use "x" instead of "x"
    to indicate that the password is shadowed (consistency with grpconv).
  * Make sure the group and gshadow files are unlocked on exit.
- groupadd
  * New option -p/--password to specify an encrypted password.
  * New option -r, --system for system accounts.
- groupdel
  * Do not fail if the group does not exist in the gshadow file.
  * Do not rewrite the group or gshadow file in case of error.
  * Make sure the group and gshadow files are unlocked on exit.
  * Fail if the system is not configured to support split groups and
    different group entries have the name of the group to be deleted.
- groupmems
  * Fix buffer overflow when adding an user to a group. Thanks to Peter Vrabec.
- groupmod
  * New option -p/--password to specify an encrypted password.
  * Make sure the group and gshadow files are unlocked on exit.
  * When the GID of a group is changed, update also the GID of the passwd
    entries of the users whose primary group is the group being modified.
- grpck
  * Fix logging of changes to syslog when a group file is provided,
    without a gshadow file.
- lastlog
  * Accept users specified as a numerical UID, or ranges of users (-user,
    user-, user1-user2).
- login
  * Use PATH and SUPATH to set the PATH environment variable, even when
    support for PAM is enabled.
  * If started as init, start a new session.
- newgrp
  * Fix segfault when an user returns to an unknown GID (either the user
    was deleted during the user's newgrp session or the user's passwd
    entry referenced an invalid group). Add a syslog warning in that case.
  * Use the correct AUDIT_CHGRP_ID event instead of AUDIT_USER_START, when
    changing the user space group ID with newgrp or sg.
- newusers
  * The new users are no more added to the list of members of their groups
    because the membership is already set by their primary group.
  * Added support for gshadow.
  * Avoid using the same salt for different passwords.
  * Fix support for the NONE crypt method.
  * newusers will behave more like useradd regarding the choice of UID or
    GID or regarding the validity of user and group names.
  * New option -r, --system for system accounts.
  * Make sure the passwd, group, shadow, and gshadow files are unlocked on
    exit.
- passwd
  * Make sure that no more than one username argument was provided.
  * Make SE Linux tests more strict, when the real UID is 0 SE Linux
    checks will be performed.
- pwck
  * Fix logging of changes to syslog when a passwd file is provided,
    without a shadow file.
- su
  * su's arguments are now reordered. If needed, use -- to separate su's
    options from the shell's options.
- sulogin
  * If started as init, start a new session.
- useradd
  * New option -l to avoid adding the user to the lastlog and faillog databases.
  * Fix the handling of the --defaults option (it required an argument,
    but should behave as -D)
  * Document the --defaults option, which was already described in the
    useradd's Usage information.
  * New option -r, --system for system accounts.
  * New options -U, --user-group and -N, --no-user-group. These options
    should replace nflg from the previous versions. Please set any -n
    option to deprecated because its meaning differs from one distribution
    to the other.
  * Make sure the passwd, group, shadow, and gshadow files are unlocked on
    exit.
- usermod
  * Keep the access and modification time of files when moving an user's home
    directory.
  * Check that the new fields set with -u, -s, -l, -g, -f, -e, -d, and -c
    differ from the old ones. If a requested new value is equal to the old
    one, no changes will be performed for that field. If no fields are
    changed, usermod will exist successfully with a warning. This avoids
    logging changes to syslog when there are actually no changes.
  * Fix the handling of -a when a user is being renamed (with -l)
- vipw/vigr
  * Recommend editing the shadowed (resp. regular) file if the regular (resp.
    shadowed) file was edited.

shadow-4.0.18.2 -> shadow-4.1.0						09-12-2007

*** security:
- chgpasswd
  When compiled with PAM support, it used the chpasswd policy file instead
  of the chgpasswd policy file. If an administrator added some restriction
  to the chgpasswd policy file, they were not taken into account.

*** general:
- Add support for SHA256 and SHA512 encrypt methods (supported by new
  libc).
- useradd: Allow non numerical group identifier to be specified with
  useradd's -g option.
- chgpasswd, chpasswd: Fix chpasswd and chgpasswd stack overflow.
- newgrp: Do not give an indication that the group has no password. Ask
  for the password, as if there were a password.
- The permissions of the suid binaries is now configurable in
  src/Makefile.am. Note that changing the permissions is not recommended.
- newgrp.c: Declare the child and pid variable at the beginning of a block.
  This fixes a compilation issue with gcc 2.95.
- login_nopam: Add support for systems with no innetgr().  On those
  systems, username with an @ will be treated like any other username
  (i.e. lookup in the local database for an user with an @). Thanks to
  Mike Frysinger for the patch.
- Add support for uClibc with no l64a().
- userdel, usermod: Fix infinite loop caused by erroneous group file
  containing two entries with the same name. (The fix strategy differs
  from 
  (https://bugzilla.redhat.com/show_bug.cgi?id=240915)
- userdel: Abort if an error is detected while updating the passwd or group
  databases. The passwd or group files will not be written.
- usermod: Update the group database before flushing the nscd caches.
- usermod: Make sure the group modifications will be allowed before
  writing the passwd files.
- Flush the nscd tables using nscd -i instead of the private glibc socket.
- usermod: Make usermod options independent of the argument order.
- newgrp: Do not request a password when a user uses newgrp to switch to
  her primary group.
- passwd: -l/-u options: edit the shadow account expiry field *in
  addition* to editing the password field.
- pwck: Remove the SHADOWPWD preprocessor check. Some check for /etc/shadow
  were always missing.
- su: Avoid terminating the PAM library in the forked child. This is done
  later in the parent after closing the PAM session.
- userdel: Fix the homedir prefix checking.
- passwd, usermod: Refuse to unlock an account when it would result in a
  passwordless account.
- Full review of the usage of getpwnam(), getpwuid(), getgrnam(),
  getgrgid(), and getspnam(). There should be no functional changes.
- gpasswd: Only read information from the local file group database. It
  writes the changes in /etc/group and/or /etc/gshadow, but used to read
  information from getgrnam (hence possibly from another group database).
- New login.defs variable: MAX_MEMBERS_PER_GROUP. It should provide a
  better support for split groups. Be careful when using this variable:
  not all tools support well split groups (in or out of the shadow
  tool suite). It fixes gpasswd and chgpasswd when split groups are used.
- Use MD5_CRYPT_ENAB, ENCRYPT_METHOD, SHA_CRYPT_MIN_ROUNDS, and
  SHA_CRYPT_MAX_ROUNDS to define the default encryption algorithm for the
  passwords.
- chpaswd, chgpasswd, newusers: New options -c/--crypt-method and
  -s/--sha-rounds to supersede the system default encryption algorithm.
- chpaswd, chgpasswd, newusers: DES is no more the default algorithm. They
  will respect the system default configured in /etc/login.defs

*** documentation:
- Generate the translated manpages from PO at build time.
- The generated manpages will change depending on the configure options.
  If you use different options than the one used for the distributed
  archive, you should re-generate the manpages.
- login.defs should now describe all the variables.
- The tools' documentation details the login.defs variables they use.

*** general:
- userdel, usermod: fixed segfault on remove home directory when it can't
  be removed; for example when it is /dev/null (fixed http://bugs.gentoo.org/139148),
- improved SELinux detection on autoconf level (based on patch by
  Dan Yefimov <dan@D00M.lightwave.net.ru>),

shadow-4.0.15 -> shadow-4.0.16						05-06-2006

*** general:
- userdel: better fix for old CERT VU#312962 (which was fixed in shadow 4.0.8):
  fixed forgoten checking of the return value from fchown() before
  proceeding with the fchmod() (based on Owl patch prepared by

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

- useradd, usermod: fixes for verify return values mkdir() and chown()
  on copy files (merge 482_libmisc_copydir_check_return_values Debian
  patch),
- login, su (non-PAM variant): export MAIL only when MAIL_CHECK_ENAB
  is enabled (Mike Frysinger <vapier@gentoo.org>),
- pgck, grpck: warn when the members of a group differ in /etc/groups
  and /etc/gshadow (fixed http://bugs.debian.org/75181),
- su: fixed exit with a status 0 when the invoked command is terminated
  by a signal which was not catched
  (fixed by Eero Häkkinen <eero17@bigfoot.com>),
- login: cancel login timeout after authentication so that patient people
  timing out on network directory services can log in with local

  - TOO MANY LOGIN... logged if PAM_MAXTRIES or failcount >= retries (was
    onl test PAM_MAXTRIES),
  - print to stderr (in addition to syslog) in case of maximum number of
    tries exceeded,
  - always prints the number of tries in the syslog entry.
  - add special handling for PAM_ABORT
  - add an entry to failog, as when USE_PAM is not defined. (#53164)
  - changed pam_end to PAM_END. This is certainly was a mistake.  PAM_END is
    pam_close_seesion + pam_end. Here, the session is still not open, we
    don't have to close it.
  - a HAVE_PAM_FAIL_DELAY is missing,
- su: fixed pam session support (patch from Topi Miettinen; fixed #57526,
  #55873, 57532 Debian bugs),

  on higher level (now is better visable where some programs exit with 126
  and 127 exit codes); added new shell() parameter (char *const envp[])
  which allow fix preserving enviloment in su on using -p, (patch by
  Alexander Gattin <xrgtn@yandex.ru>),
- su: added handle -c,--command option for GNU su compliance (merge
  437_su_-c_option Debian patch),
- login: added translate login prompt string (suggested by Evgeniy
  Dushistov),
- updated translations: ca, cs, da, el, es, eu, gl, fi, fr, it, nb, nl, pt,
  pt_BR, ro, ru, sk, sv, tl, vi, zh_CN,
- new translations: gl.
*** documentation:
- ru man pages: added new nologin(8) and updated all other man pages (by

  if it does not already exist (http://bugs.debian.org/154996),
- nologin(8) man pages added (merge 478_nologin.8.xml Debian patch).

shadow-4.0.13 -> shadow-4.0.14						03-01-2006

*** general:
- fixes in handling login.defs: $MAIL_FILE is used in userdel and usermod,
  $MD5_CRYPT_ENAB is used by crypt_make_salt, which is used by chpasswd,
  gpasswd and newusers.
  Both variables moved to PAM not dependent (447_missing_login.defs_variables
  Debian patch),
- chage: fix chage display when the last change field is set to 0.
  This is consistent with PAM (merge 427_chage_expiry_0 Debian patch),
- su: if an password is expired, su should propose to change this password
  (fixed http://bugs.debian.org/321384),
- login: added auditing support (based on Fedora patch for login from util-linux),
- useradd: merge PUG fixes from RedHat patch,
- nologin: new program,
- vipw: added a "quiet" mode (http://bugs.debian.org/190252),
- newgrp: added auditing support (by Steve Grubb <sgrubb@redhat.com>),
- switch over to a new logging function (by Steve Grubb <sgrubb@redhat.com>),
- userdel: fix incorrect audit record in userdel
  (https://bugzilla.redhat.com/bugzilla/174392),
- userdel: remove the user's group unless it is not really a user-private group
  for better PUG support (based on FC patch),
- userdel: make the -f option force the removal of the user's group (even if it
  is the primary group of another user)
  (merge 453_userdel_-f_removes_group Debian patch),
- usermod: rewrited for use getopt_long() (Christian Perrier <bubulle@kheops.frmug.org>),
- grpck: fixed segmentation fault on using -s when /etc/gshadow is empty (fix by
  Tomasz Lemiech <szpajder@staszic.waw.pl>),
- passwd: remove handle -f, -g and -s options.
- added handle -s/--shell, -m/-p/preserve-environment options like GNU su
  (based on patches from Debian submited by
  Nicolas François <nicolas.francois@centraliens.net>)
- su: export $USER and $SHELL as well as $HOME (http://bugs.debian.org/11003 and
  http://bugs.debian.org/11189),
- su, vipw: rewrited for use getopt_long(),
- su: log successful/failed through syslog (http://bugs.debian.org/190215),
- updated translations: ca, cs, da, eu, fi, fr, it, pl, pt, ru, sv, tl, vi,
- new translations: gl.
*** documentation:

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

  directory but not change the ownership to the target user/group. This
  makes httpd Option SymlinkIfOwnerMatch break for default weg pages
  including symlinks placed into /etc/skel/public_html for example.

- added new de translation (by Frank Schmid <frank@cs-schmid.de>).
- fixed building --with-shared: swapped utent (in src/login.c and
  libmisc/utmp.c) and pwent (in libmisc/suauth.c and src/su.c)
  definition/extern (by Dimitar Zhekov <jimmy@is-vn.bg>).
- minor changes and updates in man pages (also merged
  shadow-4.0.0-owl-man.patch by Solar Designer <solar@openwall.com>).

shadow-4.0.1 => shadow-4.0.2						 17-02-2002

- resolve many fuzzy translations also all this which may cause problems on
  displaing long uid/gid,
- allow use "$" on ending in cereated by useradd usermname accounts for allow
  create machine acounts for samba (thanks to Jerome Borsboom
  <borsboom@tch.fgg.eur.nl> for point this problem in 4.0.1),
- fix small but ugly bug in configure.in in libpam_mics library detection.

shadow-4.0.0 => shadow-4.0.1

- added ability to log session closes in newgrp
  (Joseph Parmelee <jparmele@wildbear.com>),
- add -pcs to .indent.pro file and reindent all code in src/,
- remove "\n" from all SYSLOG() messages,
- finish integrate AGING code into SHADOWPW,
- remove handle old HAVE_USERSEC_H code,
- updated ja and added hu man pages,
- applied patches by Solar Designer <solar@openwall.com>:
  shadow-4.0.0-owl-chage-drop-priv.diffd
  shadow-4.0.0-owl-chage-ro-no-lock.diff:
    Added locks which are needed when doing r/w accesses, not when running
    as root.  If root does read-only, there's no lock needed. Added missing
    "#include <errno.h>" for above (me).
  shadow-4.0.0-owl-warnings.diff
    Olny one fix from this patch was aplayd because other was fixed few days
    before :)
  shadow-4.0.0-owl-check_names.diff
    Merge only prat this patch with checking login name matching; checking
    is login string isn't longer than possible it will be good prepare using
    probably _POSIX_LOGIN_NAME_MAX from <bits/posix1_lim.h>,
  shadow-4.0.0-owl-chage-drop-priv.diff
  shadow-4.0.0-owl-pam-auth.diff
    Merge part with reorder initialize PAM and checkin is chage is runed by
    root or not - now chage can be runed from non-root account for checking
    by user own account information (if PAM enabled).
- fixes for handle/print correctly 32bit uid/gid (Thorsten Kukuk <kukuk@suse.de>),
- implemented functions for better reloading the nscd cache (per NSS map)
  (Thorsten Kukuk <kukuk@suse.de>),
- fixed warnings "not used but defined" on compile using gcc 3.0.x 
  (bulletpr00ph <bullet@users.sourceforge.net>),
- added ja, ko translations found in SuSE,
- added symlinks: newgrp -> sg, vipw -> vigr,
- added vigr(1) man page as roff .so link to vipw(1),
- added sg(1) man page as roff .so link to newgrp(1),
- installed fix for SEGV when using pwck -s on /etc/passwd file with
  empty lines in it.
  
shadow-20001016 => shadow-4.0.0						 06-01-2002

- fix bug discovered and fixed by Marcel Ritter
  <Marcel.Ritter@rrze.uni-erlangen.de>
  Due to a big buffer size in lib/commonio.c this error does only appear
  if a line gets longer than 4096 bytes (there are probably very few people
  stumbling across this).
  Ths bug can be exposed by trashing /etc/groups file using useradd with script:
	#!/bin/sh
	typeset -i NUM
	NUM=0
	groupadd demogroup
	while [ $NUM -le 1000 ]; do
	   useradd -g demogroup -G demogroup -p "NONE" user$NUM
	   NUM=$NUM+1
	done
- remove limit 32 to groups per user by (the same user can belong to
  more than 32 groups) by use sysconf(_SC_NGROUPS_MAX) instead constant
  NGROUPS_MAX (patch by Radu Constantin Rendec <radu.rendec@ines.ro>)
  NOTE: it probably need testing on other system for add
  some condition for using sysconf(_SC_NGROUPS_MAX) or NGROUPS_MAX constant,
- added -s option to {pw,grp}ck to sort checked files by UID/GID,
- drop detecting is pam_strerror() need one or two arguments. Instead using
  PAM_STRERROR() macro use directly pam_strerror() function with two
  arguments. pam_strerror() with one argument is obsoleted,
- adde ja man pages (probably some man pages need update),
- much better automake support,
- added pt_BR man pages for gpasswd(1), groupadd(8), groupdel(8),
  groupmod(8), shadow(5) (man pages for other nations also are welcome),
- mamny small fixes and updates nad improvements in man pages,
- aplayed Debian patch to man pages for shadowconfig,
- remove limit to 6 chars logged tty name (012_libmisc_sulog.c.diff Debian
  patch).

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

shadow-20000902 => shadow-20001012

- removed /redhat directory with obsoleted files (partialy rewrited spec
  file is now in root directory),
- aplayed shadow-19990827-group.patch patch from RH wich prevents adduser
  overwrite previously existing groups in adduser,
- added PAM support for chage (bind to "chage" PAM config file) also
  added PAM support for all other small tools like chpasswd, groupadd,
  groupdel, groupmod, newusers, useradd, userdel, usermod (bind to common 
  "shadow" PAM config file) - this modificaytions mainly based on
  modifications prepared by Janek Rękojarski <baggins@pld.org.pl>,
- many small fixes and improvments in automake (mow "make dist"
  works correctly),
- added cs translation (Jiri Pavlovsky <Jiri.Pavlovsky@ff.cuni.cz>).

shadow-20000826 => shadow-20000902

This is probably the last release from me.
Tomasz Kloczko <kloczek@rudy.mif.pg.gda.pl> is the new maintainer.
Good luck!

(I'm still interested to know what is going on with this package,
which is fairly important to many Linux distributions, so please
Cc: marekm@linux.org.pl in any related discussions - just don't
expect me to respond quickly...)

Previous warning still applies - be careful!

- applied some of the Red Hat patches (revised slightly), thanks to
  Bernhard Rosenkraenzer <bero@redhat.de>: fix for truncated long
  lines (>8K) in /etc/group, send SIGHUP to nscd (caching daemon
  in glibc 2.1.x) after changing anything, add usermod -L and -U
  options, remove LOG_CONS from openlog(), chage -d and -E handles
  dates in yyyy-mm-dd format ('/' is not required)
- various cleanups

shadow-19990827 => shadow-20000826

WARNING: this release is not tested (other than that it compiles for me),
please be careful.  Previous release was a year ago, so it is really time
to release something and start looking for a new, better maintainer...
(I've been extremely busy recently.  Credit for most of the real work,
such as complete PAM support, should go to Ben Collins <bcollins@debian.org>
who maintains this package for Debian.)

- merged most of the changes from Debian (not all of them yet, PAM support
  should be complete but is not tested - need to upgrade to potato first)
- added Polish translations of manual pages from PLD
- change sulog() to not depend on global variables oldname, name
- try to not follow symbolic links when deleting files recursively
  in userdel (still not perfect, safest to do it in single user mode)
- removed workarounds for ancient (pre-ANSI) C compilers - use gcc!
  (a few ANSI C constructs were used already, and no one complained)
- updated author's e-mail address (jfh@bga.com -> jfh@austin.ibm.com)

shadow-19990709 => shadow-19990827

- upgrade to autoconf-2.13, automake-1.4, libtool-1.3.3

- i18n: added Swedish translation by Kristoffer Brånemyr <ztion@swipnet.se>
- logoutd no longer reads /etc/logoutd.mesg at startup - instead, read
  it when sending to luser's tty (no need to reload with SIGHUP)
- added support for "usergroups" feature often found in Linux distributions
  (if USERGROUPS_ENAB in login.defs set to "yes", uid != 0, uid == gid, and
  username == groupname, then set umask to 002 instead of 022)
- Debian: pwck and grpck are now run from a daily cron job (root will
  receive an e-mail if something is wrong), and at system startup
- added support for setting umask in /etc/limits
- when using OPIE, re-prompt with echo on after empty password was entered
- GETPASS_ASTERISKS now run time configurable (login.defs)
- getpass() now uses stdin and stderr (not stdout) if it can't open /dev/tty
- getpass() allows all input to be erased using Control-U, and beeps when
  too many characters are entered
- removed obsolete sgtty support, in 1999 everyone should have termios :)
- Debian: tar wrapper no longer needed to build packages as non-root user
  (install libtricks, and use "dpkg-buildpackage -rfakeroot" instead)
- Debian: changes for GNU Hurd by Marcus Brinkmann <brinkmd@debian.org>:
  dpkg-architecture, cross compilation, only build passwd, add
  etc/login.defs.hurd conffile, conditionalize CBAUD
- newgrp sets $HOME before running the new shell
- both "sg group command" (usage message) and "sg group -c command"
  (man page) work, updated both the usage message and the man page :)
- i18n: added missing _() for some translatable strings

shadow-19990607 => shadow-19990709

- added PAM support to chfn and chsh (thanks to Thorsten Kukuk)
- fixed a bug in newgrp if the user is in >= 17 groups
- added @LIBSKEY@ to LDADD for all programs (for some reason,
  almost all programs need it if skey/opie support is enabled)
- changed grpconv/grpunconv to compile with --disable-shadowgrp
- changed faillog to do something (assume -p) with no options specified
- updated version of the udbachk passwd/shadow/group file integrity
  checker (contrib/udbachk.v012.tgz)

shadow-19990307 => shadow-19990607

- upgraded to libtool-1.2, latest config.{guess,sub}
- added missing #include "defines.h" in libmisc/login_desrpc.c - thanks
  to almost everyone for reporting it :-)
- moved PAM-related defines to pam_defs.h

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

shadow-981228 => shadow-19990307

- always require password for root logins (even with NO_PASSWORD_CONSOLE)
- workaround for RedHat's CREATE_HOME feature in /etc/login.defs
- changed to Y2K compatible version numbering
- more Y2K fixes, use the ISO 8601 date format (yyyy-mm-dd) for default
  values of user-entered dates (you can still enter dates in any format
  supported by GNU date)
- oops, added doc/README.nls to list of files to distribute
- added missing sanitize_env() call to src/login.c
- debian/rules installs /bin/login non-setuid by default, just in case...
- build Debian packages with cracklib support (depends on cracklib-runtime)

shadow-980724 => shadow-981228

- login now clears the username in argv[] (in case someone types the
  password instead of username, by mistake)
- i18n support, Greek translation (Nikos Mavroyanopoulos), see README.nls
- updated author's e-mail address (jfh@tab.com -> jfh@bga.com)
- new getpass() replacement that displays *'s (Pavel Machek)
- no password required when logging in from ttys listed under
  NO_PASSWORD_CONSOLE in login.defs (Pavel Machek)
- fixed limits code so RLIMIT_AS should work
- upgraded to Debian 2.0
- built a new machine (P2 350MHz, 64MB RAM) so the thing can be compiled
  in reasonable time again
- upgraded to automake-1.3, libtool-1.0h (also new config.guess and
  config.sub that work on i686)
- usermod fixed to handle group names starting with digits (not recommended)

shadow-980626 => shadow-980724

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

shadow-980529 => shadow-980626

- fixed bug in commonio_lock() (infinite recursion if lckpwdf() not
  used and database cannot be locked), thanks to Jonathan Hankins
- fixed bug in copy_tree() (NUL-terminate readlink() results),
  thanks to Lutz Schwalowsky
- no need to press Enter after Ctrl-C to interrupt password prompt
- removed a few harmless gcc warnings
- secure RPC login disabled if <rpc/key_prot.h> not found (glibc 2.0)

- pwconv.8: documented that it may fail on invalid password files

shadow-980417 => shadow-980529

- fixed "interesting" strzero() bug introduced by me in 980417:
  strzero(cp) didn't work as intended (the macro used a local
  variable called "cp" - oops...); Leonard N. Zubkoff was the
  first person to report it - thanks!
- fixed usermod -e to accept empty argument (like useradd),
  thanks to Martin Bene
- several changes from Debian 980403-0.2, see debian/changelog
- added contrib/shadow-anonftp.patch (not yet merged, sorry...)
  thanks to Calle Karlsson

shadow-980403 => shadow-980417

- fixed login session limits (again - broken since 980130)
- more symbolic constants for exit status values
- fixed logoutd to work with 8-character usernames in utmp
  (no room for terminating NUL!)
- various fixes to make the code more glibc2-friendly
- updated doc/cracklib26.diff (fix for empty gecos, etc.)
- updated the files in redhat/ from shadow-utils-970616-11.src.rpm
  (RH 5.0 updates)

shadow-980130 => shadow-980403

- security: su now creates the sulog file (if enabled and doesn't
  already exist) with umask 077
- hopefully removed arbitrary group size limits (not yet for
  shadow groups though - sgetsgent() still needs a rewrite,
  but I don't want to delay this release any longer...)
- fixed NULL dereference in groupmod -n

shadow-971215 => shadow-980130

- Debian binary packages can be built without root privileges
  (tar wrapper - debian/tar.c)
- new subdir "redhat" (needs more work, see redhat/README)
- in several places, exit(127) if exec fails with ENOENT, and
  exit(126) on other errors (as in ksh and bash)
- renamed getpass() and md5_crypt() to libshadow_* to avoid name
  conflicts with libc functions - md5_crypt() is also in libcrypt.a
  on Linux/PPC, thanks to Anton Gluck <gluc@midway.uchicago.edu>
- handle crypt() returning NULL (possible according to Single Unix
  Spec) more gracefully (exit instead of SIGSEGV)
- fixed bug in putgrent() that showed up when realloc() moved the
  buffer while expanding it, thanks to Floody <flood@evcom.net>
- fixed bug in login session limits (with a limit set to N logins,
  only N-1 logins were allowed), thanks to Floody <flood@evcom.net>
- upgraded to libtool-1.0h (now recognizes GNU ld on Debian 1.3.1)
- newer config.guess and config.sub (should work on x86 for x > 5)
- removed doc/automake-1.0.diff (obsoleted by automake-1.2)
- added doc/cracklib26.diff (some patches for cracklib-2.6)
- documented more (not all yet) login.defs(5) settings
- replaced more exit status numeric values with #defines
- shadow-utils.spec now generated from shadow-utils.spec.in
  (so I don't have to edit version numbers for every new release)
- groupadd -f option, based on RedHat's shadow-utils-970616-9 patch
  ("force" - exit(0) if the group already exists); other RedHat-
  specific options not added yet (best done in a perl script that
  runs useradd/usermod/groupadd - see Debian's adduser-3.x)
- added -O option (override login.defs values) to useradd and groupadd
- if usermod can't update the group file(s), exit(10) but update the
  password file(s) anyway (as documented by Solaris man page)
- useradd should no longer set sp_expire to the current date (oops)
- configure.in: added --enable-desrpc, check for gethostbyname in libc
  before trying libnsl (necessary for Solaris; not for Linux or Irix,
  even though libnsl may be present), fixed pw_age/pw_comment/pw_quota
  detection, setpgrp vs. setpgid, other minor tweaks
- various */Makefile.am tweaks
- login.defs: added FAKE_SHELL - program to run instead of the login
  shell, with the real shell in argv[0] (Frank Denis)
- login.defs: ignore case in yes/no settings
- more E_* defines instead of hardcoded numbers for exit()
- added sanitize_env() for setuid programs
- login_desrpc() checks for getnetname() errors
- new password is not "too similar" if it is long enough
- replacement strstr() was static, no one noticed :-)
- {pw,spw}_lock() and {pw,spw}_unlock() track the lock count and call
  lckpwdf() and ulckpwdf() as needed, *_lock_first() hack removed
- login sets $REMOTEHOST for remote logins
- added newgrp -l option (Single Unix Spec, same as "-")
- EXPERIMENTAL shared lib support using libtool (libshadow.so saves about
  200K of disk space on Linux/x86), enabled by default if supported by
  the system, use ./configure --disable-shared if it causes any problems.
  Warning: libshadow.so is intended for internal use by this package
  only - binary compatibility with future releases is not guaranteed.
  There should be no need to link any other programs with libshadow.so -
  the libshadow.so -> libshadow.so.x.x symlink is unnecessary.
- pam_strerror() takes one or two arguments, depending on the Linux-PAM
  version (!) - added check to configure; fixed do_pam_passwd prototype
- libmisc/login_access.c should compile on Linux/PPC and Solaris
- added information about the new ftp site to doc/README.mirrors

shadow-971001 => shadow-971215

- added workaround for NYS libc 5.3.12 (RedHat 4.2) bug to grpck
- updated the RPM .spec file
- renamed rlogin() to do_rlogin() to avoid Linux/PPC build problem
  (glibc defines something else named "rlogin" in utmpbits.h ?)
- added MD5 checksums in Debian packages
- added -p and -g options to vipw (edit the password or group file
  respectively, regardless of the command name in argv[0])
- removed old DBM support (NDBM code is still there)
- fixed a bug in gpasswd: current username was incorrectly identified as
  "root" because of setuid(0) done too early.  It may be a security hole
  when using shadow groups - if "root" is listed as a group administrator,
  any user can add/remove members in that group.  Thanks to Jesse Thilo.
- gpasswd now logs which user (root or group admin) made the changes
- passwd now uses $PATH to search for the chfn, chsh, gpasswd commands
- newgrp and add_groups() allocate supplementary group lists dynamically
- moved check_shell() from src/chsh.c to libmisc/chkshell.c
- CHFN_RESTRICT in login.defs can now specify exactly which fields may be
  changed by regular users (any combination of letters "frwh")
- fixed contrib/pwdauth.c segfault with non-existent usernames
- minor change in lib/getdef.c to handle quotes better (Juergen Heinzl)
- new date parsing code (from GNU date) used by useradd, usermod, chage
- upgraded to automake-1.2, added libtool-0.7 (no libshadow.so yet)
- converted code to ANSI C, added ansi2knr (untested - use gcc!)
- fixed useradd -G segfault (one '*' that shouldn't be there)
- allow 8-bit characters in chfn
- added support for RLIMIT_AS (max address space) in libmisc/limits.c
- changed the handling of NIS plus entries in password files
- some more tweaking in various debian/* files
- logoutd uses getutent() instead of reading utmp file directly
- fixed lckpwdf() called twice (and failing) when changing password
  if the user is not listed in /etc/shadow (Mike Pakovic)
- erase and kill characters left unchanged if not defined in login.defs

shadow-970616 => shadow-971001

- Debian: mkpasswd no longer installed (dbm files not supported)
- chpasswd checks for shadow/non-shadow at run time, too
- added chpasswd -e (input file with encrypted passwords) - Jay Soffian
- changed libmisc/login_access.c as suggested by Dave Hagewood
- replaced sprintf() with snprintf() in several places
- added lib/snprintf.[ch] (from XFree86) for systems without snprintf()
- minor tweaks in contrib/adduser.c (/usr/local -> /usr)
- non-root users can only run su with a terminal on stdin
- temporarily disabled DES_RPC because getsecretkey() causes login to hang
  for 5 minutes on at least one RH 4.0 system.  Not sure if this is a bug
  in libc, or system misconfiguration.  Needs further investigation.
- check for strerror() and -lrpcsvc (should compile on SunOS again)
- fixed free() called twice in libmisc/mail.c
- added information about mirror sites (doc/README.mirrors)
- updated pwconv.8 and pwunconv.8 man pages
- "make install" now installs pwconv, pwunconv, grpconv, grpunconv
- pwauth.8 no longer installed (AUTH_METHODS not supported by default)
- corrected su.1 man page ($SHELL not used)
- no need for --with-md5crypt if the MD5-based crypt() is already in libc
  (or another library specified in /etc/ld.so.preload - Linux ld.so 1.8.0+)
- cleaned up PASS_MAX in getpass() (127 always assumed)
- default editor for vipw changed from /bin/ae to a real editor :)

shadow-970601 => shadow-970616

- fixed execlp call (missing NULL) in src/vipw.c
- vipw now preserves permissions on edited files
- commented out the xdm-shadow hack in shadowconfig
- improved RedHat spec file (Timo Karjalainen)
- updated mailing list information
- added information about the shadow paper (doc/README.shadow-paper)
- renamed doc/console.c.spec (confused RPM)

shadow-970502-2 => shadow-970601

- fixed a typo in libmisc/mail.c causing login to segfault
  if MAIL_CHECK_ENAB=yes (sorry!)
- patches for OPIE support (Algis Rudys) (untested)
- programs that modify /etc/passwd or /etc/shadow will use
  lckpwdf() if available
- now compiles with PAM support! (still untested)
- cosmetic error message changes (prefixed by argv[0]:)

shadow-970216 => shadow-970502-2

- shadow group support fixes (grpconv didn't work - for some
  reason, putsgent() returns 1 instead of 0 on success;
  now -1 = failure, anything else = success)
- upgraded to autoconf-2.12
- pwconv and pwunconv now follow other UN*X systems and SVID3
  (modify files in place), original versions moved to "old"
- scologin.c moved to "old" (it was only for SCO Xenix) so
  people stop sending patches for scologin.c gcc warnings :)
- don't use the MD5* functions in libmisc/salt.c (glibc has
  the new md5 crypt(), but no <md5.h> and MD5* functions!)
- support for MkLinux, Solaris, JIS, Qmail (Frank Denis)
- "passwd -S -a" now really works
- support for Debian, vipw, a few fixes (Guy Maor)
- src/login.c radius bug fix (Rafal Maszkowski)
- ISSUE_FILE_ENAB -> ISSUE_FILE in the sample /etc/login.defs
- fixes for glibc and DES_RPC (Thorsten Kukuk)
- limits.5 man page (Luca Berra)
- expiry will work setgid shadow too, removed euid 0 check
- added check for a64l() to configure (glibc)

shadow-961025 => shadow-970216

- major rewrite of *io.c (no more 4 copies of almost identical code)
- use fsync() (if available) instead of sync() when updating password files
- use fchmod() and fchown() if available
- keep the NIS "plus on a line by itself" entries at end of passwd/group
- configure checks location of passwd/chfn/chsh programs (/usr/bin or /bin)
- passwd -S -a: list information about all users (root only)
- passwd -k: change only expired passwords
- passwd -q: quiet mode
- first attempt at PAM support in passwd
- passwd updates the non-shadow password if /etc/shadow exists but the
  user has no shadow password
- passwd logs who changed the password, added hook to allow non-root
  administrators who can change passwords (not implemented yet)
- su sets $HOME even without the "-" option (suggested by Joey Hess)
- added -p (set encrypted password) option to useradd and usermod
  (idea from hpux10 - undocumented option used internally by SAM)
- useradd -D -e does the right thing (set default expiration date)
- USERDEL_CMD in login.defs instead of hardcoded {ATRM,CRONTAB}_COMMAND
  because there are just too many systems that need different commands
- removed #ifdef FAILLOG_LOCKTIME (now always enabled), warning: the
  faillog file format has been changed (somewhere between 960129 and
  960810), please truncate the old file (if any) to zero length
- ISSUE_FILE (may be different from /etc/issue) instead of ISSUE_FILE_ENAB
- wtmp, lastlog, faillog file location guessed by configure
- separate checks for invalid user and group names, max username length
  based on struct utmp (it's not always 8 characters)
- pwck and grpck now check for invalid user/group names
- pwck -q (quiet, report only serious problems) option added
- separate cleaner sgetpwent() without the NIS magic
- NIS entries ignored (never changed) by *io.c, pwck, grpck
- various code cleanups
- new get_my_pwent() function for getting my own username, uid etc.
- faillog opens the file read-write if possible (even if not root)
- passwd -S allowed for normal users (for their own uid only)
- handle the case of login denied to passwordless accounts better
  ("Login incorrect" without "Password:" prompt looks strange)
- corrected author information and removed a copyright restriction

shadow-960925 => shadow-961025

- fixed a few typos in shadow group code
- don't check for names starting with 'r' to determine if the shell
  is restricted, use /etc/shells instead (for the "rc" shell)
- removed extra definition of LASTLOG_FILE in configure.in
- expiry no longer segfaults if no /etc/shadow
- userdel -r "can't remove mailbox" warning no longer printed on success
- useradd exit codes changed to match hpux10 man page
- fixed possible fd leak etc. in file locking code (lib/commonio.c)

shadow-960920 => shadow-960925

- bug fixes to the new environment code using malloc
- use hardcoded names instead of basename(argv[0]) for openlog() in programs
  that users can run (chage, chfn, chsh, gpasswd, login, newgrp, passwd, su)
- small fix to isexpired(), and use it in passwd as well
- use strftime() and strptime() if available
- added chmod 600 /etc/passwd- at the end of pwconv5 (backup file may
  contain encrypted passwords!)
- pass size to change_field (chage, chfn, chsh) instead of assuming BUFSIZ
  (nothing bad happened yet, just a cleanup)
- gpasswd should work with both shadow and non-shadow group passwords
- detect unsupported options if no shadow (gpasswd, useradd, usermod)
- passwd -e for sunos4 (ATT_AGE), untested
- read environment from file (ENVIRON_FILE in login.defs), idea from ssh
- small fix to l64a()
- passwd prints a message after password successfully changed (for things
  like poppassd which run passwd and expect some output)
- passwd logs if password was changed by root (as opposed to a luser)
- passwd uses current uid if no username argument and getlogin() fails

shadow-960910 => shadow-960920

- use malloc for environment variables, no more MAXENV (Juergen Heinzl)
- newusers should work with both shadow and non-shadow passwords
  (still left to do: chpasswd, gpasswd)
- login-static no longer compiled by default
- more SYSLOG() macros

shadow-960810 => shadow-960910

- updated README.linux to point to the new ftp site
- chfn and chsh optionally (CHFN_AUTH) prompt for password like util-linux
- man pages now closer to LDP standards (Ivan Nejgebauer)
- newgrp uses SYSLOG_SG_ENAB (not SU) as in the /etc/login.defs comments
- obscure.c fixed to compile with HAVE_LIBCRACK
- cosmetic message changes in age.c
- utmp open error check fixed in utmp.c
- grpunconv added (Michael Meskes)
- login reports invalid login time, not "Login incorrect" (Ivan Nejgebauer)
- logoutd sets OPOST before writing to the tty (Ivan Nejgebauer)
- sulogin: don't use syslog(), other minor changes (Ivan Nejgebauer)
- passwords can be changed if sp_max == -1 (now considered infinity)
- usermod: don't use sizeof(struct lastlog) when writing to faillog (ugh)
- started replacing lots of #ifdef USE_SYSLOG with cleaner macros
- contrib/rpasswd.c added (Joshua Cowan)
- PASS_MAX is 127 with MD5_CRYPT (not just for Linux - sunos4 too...)
- workarounds for a RedHat NYS libc getspnam() bug (if /etc/shadow
  doesn't exist, it succeeds and returns sp_lstchg==0 instead of -1).

shadow-960129 => shadow-960810

- automake, configure checks for libcrypt and libcrack (Janos Farkas)
- added --enable-shadowgrp to configure (shadow groups disabled by default)
- should compile on SunOS 4.1.x - but it does NOT mean that it works :-)
- login sets HUSHLOGIN=TRUE or FALSE (for shell startup scripts etc.)
- hopefully removed all the rcsid warnings
- contrib/atudel perl script to remove at jobs (thanks to Brian Gaeke)
- resource limits (Cristian Gafton)
- workaround for buggy init/getty(?) leaving junk in ut_host on RedHat
- more fixes in man pages
- pwck and grpck no longer suggest to run mkpasswd if *DBM not compiled in
- most programs (groupadd, groupdel, groupmod, grpck, login, passwd, pwck,
  su, useradd, userdel, usermod) should now work with both shadow and
  non-shadow passwords/groups (check for /etc/shadow and /etc/gshadow at
  run time); a few programs still left to do
- mailbox mv/chown/rm in usermod/userdel (suggested by Cristian Gafton)
- new contrib/adduser.c from Chris Evans
- lots of other minor changes
- source tree reorganization, GNU autoconf, portability cleanups
- basename() renamed to Basename() to avoid name space confusion
- new programs to create /etc/shadow and /etc/gshadow: pwconv5, grpconv
- newgrp cleanup and a few fixes
- useradd uses PASS_MAX_DAYS, PASS_MIN_DAYS and PASS_WARN_AGE
- don't make the first group member the group admin by default
  (define FIRST_MEMBER_IS_ADMIN to get the old gpasswd behaviour)
- password aging constants, NGROUPS_MAX and syslog stuff in only one
  place (defines.h) instead of repeating it in all source files...
- added userdel -r safety check (refuse to remove the home directory
  if it would result in removing some other user's home directory)
- usermod -u now correctly checks for non-unique uid (unless -o)
- sync() after updating password files, just to be more safe
- "make install" should install /etc/login.defs if it doesn't exist
- new option to control what happens if we can't cd to the home directory
  (DEFAULT_HOME in /etc/login.defs)
- enter the home directory as the user, not as root (for NFS etc.)
- added check for Slackware bugs (nobody UID -1) in pwck and grpck
- new CONSOLE_GROUPS feature (thanks to pacman@tardis.mars.net), it is
  possible to add specified groups (floppy etc.) for console logins
- new faillog feature: lock account for specified (per-user) time since
  the last failure after exceeding the failure limit
- new man pages (gpasswd.1, login.access.5, suauth.5)
- fixes in man pages, renamed *.4 to *.5
- new "contrib" directory (two adduser programs)
- changed some "system" to "feature" #ifdefs (autoconf someday...)
- sulogin no longer requires to be run from init, should work from rc
  scripts too
- changes to prevent unshadowing with libc SHADOW_COMPAT (get info
  using xx_locate(), modify it and call xx_update(), don't write back
  anything returned by getpwnam() etc.)
- stupid bug fixed in lastlog.c
- don't move non-directories in "usermod -m"
- don't log unknown usernames (passwords mistyped for usernames) (lmain.c)
- macros to get around ancient compilers which don't like prototypes
- make more use of "const" (not everywhere yet)
- added #ifdef AUTH_METHODS - very few people use administrator defined
  authentication methods because many programs are not aware of them;
  not supporting them makes the code simpler
- new "save" and "restore" Makefile targets, thanks to Rafal Maszkowski
- sgetgrent() in libshadow.a is optional, some versions of libc have it,
  see HAVE_SGETGRENT in config.h (grent.c)
- don't use continued lines in /etc/group, the standard getgr*() functions
  don't support that (grent.c)
- removed the third main() argument (according to libc docs, not allowed by
  POSIX.1 - use environ instead) (lmain.c, smain.c, newgrp.c, sulogin.c)
- login access control (lmain.c, login_access.c)
- added copyright notice to login_access.c (from logdaemon-5.0)
- detailed su access control (smain.c, suauth.c) - thanks to Chris Evans
- added closelog() in su before executing the shell (smain.c)
- getting current user name changed (smain.c)
- "x" instead of "*" in pw_passwd, consistent with pwconv (useradd.c)
- getpass() shouldn't return NULL except on errors (getpass.c)
- moved isexpired() to isexpired.c (now part of libshadow.a) from age.c
- SunOS4-like passwd -e (force change on next login) (isexpired.c, passwd.c)
- can use shadow support in new versions of Linux libc instead of libshadow.a,
  see HAVE_SHADOWPWD, HAVE_SHADOWGRP in config.h.linux (shadow.c, gshadow.c)
- "no shadow password" not logged, the same /bin/login should work with both
  shadow and non-shadow passwords (lmain.c)
- some cleanup in various places (lmain.c, passwd.c)
- new program to verify username/password pairs, for xlock etc.; it is not
  installed by default, read the comments first (pwdauth.c)
- authentication programs run with empty environment for safety (pwauth.c)
- added missing fstat error checks (faillog.c, lastlog.c, setup.c, *io.c)
- common code separated from *io.c (commonio.c)
- ownership and permissions on password files are now preserved (we may try
  to make more use of setgid and setuid non-root programs in the future)
- added (untested) MD5-based crypt() from FreeBSD (md5crypt.c), see
  MD5_CRYPT in config.h.linux and MD5_CRYPT_ENAB in login.defs.linux
- termios/termio/sgtty macros cleaned up a bit

shadow-951218 => shadow-960129

Emergency bug fix release - no new features since 951218.  There are many
new changes, but this bug really can't wait until they are tested.

Probably all previous versions of the shadow suite have a serious bug which
makes it possible to overwrite the stack by entering very long username at
the login prompt.  This can give root access to any remote user!

Changed the maximum size in login.c from BUFSIZ (1024) to 32 (to match
size of the array in lmain.c).  Aaargh!!!

shadow-951203 => shadow-951218

Changes:
- Linux utmp handling fixes (utmp.c)
- last failure date printing fixes (failure.c)
- minor fix to compile with USE_CRACKLIB (obscure.c)
- eliminated the use of snprintf (env.c, lmain.c, login.c, shell.c, smain.c)
- basename.c added, replacing duplicated code in various places
- "su -" runs the shell with '-' in argv[0] again (smain.c)
- removing at/cron jobs cleaned up (userdel.c)
- /etc/gshadow should not be world-readable (sgroupio.c)
- if fflush() failed, files were not closed (*io.c)
- login prompt is now "hostname login: " on Linux (lmain.c, login.c)
- "save" and "restore" targets commented out (don't work) (Makefile.linux)
- some minor cleanups for gcc -Wall (unused variables etc.)
- removed README.FIRST (copyrights are OK now)
- updated ANNOUNCE, README.linux, WISHLIST
- as suggested, converted to RCS

shadow-3.3.2-951127 => shadow-951203-jfh

Changes:
- Added the BSD-style copyright to all of the files.  Any files with the
  old copyright have multiple copyright holders and need to be cleanroomed
  to produce BSD-style copyrightable files, or I need to get the consent
  of the others to change the copyright.
- Changed the ANNOUNCE file to not refer to the README.FIRST file.  Now
  that all of the files should have the correct copyright there is no need
  to refer to that e-mail message.
- Changes SCCS strings to "%W% %U% %G%".  Marek needs to either convert to
  RCS or check into SCCS and then checkout.  I'd suggest using RCS ;-)

  jfh@rpp386.cactus.org

shadow-3.3.2-951106 => shadow-951127

Note: for now this code only supports Linux.  All the #ifdef's are there
(and will be; support for at least SunOS 4.1.x would be nice) but:
- I had to fix some potential security problems resulting from sloppy
  coding (no bounds checking), and it was easier for me to use snprintf()
  (not available on many systems, unfortunately), I'll fix that later.
  Old versions of Linux libc don't have snprintf() either, and the one
  in libbsd.a ignores the max size - don't use it!  (libc-4.6.27 is OK)
- I am lazy and only updated Makefile.linux and config.h.linux this time
- I don't have root access to non-Linux systems (this means no testing)
- this code needs some major reorganization, which will (hopefully)
  make porting easier

Changes:
- some code cleanup, prototypes.h, defines.h, Makefile and config.h changes
- login can be statically linked (not that I think it's a good idea, better
  fix the telnetd, but paranoid people will like it :-)
- login is installed non-setuid by default
- check for NULL from getpass()
- wipe cleartext password from getpass() when no longer needed (pwauth.c)
- use standard "Password: " prompt by default (pwauth.c)
- hopefully fixed bogus sigaction() stuff (Linux only) (getpass.c)
- oops, setrlimit wants bytes, ulimit wants 512-byte units (lmain.c)
- Linux has <lastlog.h>
- print ll_host on Linux too (lmain.c)
- size checking in various places (setuid root programs, argh!)
- preserve TERM from getty (lmain.c)
- don't ignore SIGHUP (lmain.c)
- :%s/setenv/set_env/g (setenv(3) conflict) (env.c, lmain.c, login.c)
- remove LD_xxx (env.c)
- use bzero() instead of memset() for BSD portability and less #ifdef's
  (if the system has no bzero(), implement it as a macro using memset())
- the above fixes wrong order of memset() parameters (log.c)
- use getutent/pututline instead of doing it by hand (utmp.c)
- added the new settings to login.defs.linux
- added login_access.c to the distribution (not used yet)

==========

shadow-3.3.2 => shadow-3.3.2-951106

- added dummy pad.c and #ifdef'ed out references to pad_auth (pwauth.c)
- malloc/strdup error checking, hopefully no more core dumps...
- define HAVE_RLIMIT instead of HAVE_ULIMIT for Linux (config.h.linux)
- changed pathnames on Linux to conform to new FSSTND (/var/log etc.)
- larger buffer for cipher, for md5 crypt() if and when (encrypt.c, passwd.c)
- use POSIX termios whenever possible on Linux
- list.c, removed add_list/del_list from gpmain.c, user{add,del,mod}.c
- strtoday.c, removed duplicates from chage.c, useradd.c, usermod.c
- login -h only for root (lmain.c)
- login -r not needed for Linux (lmain.c)
- sample login.defs modified for Linux (login.defs.linux)
- swapped chfn USAGE and ADMUSAGE (chfn.c)
- added -u to passwd usage (passwd.c)
- no #! check necessary for Linux (shell.c)
- define OLD_CRON for some old incompatible Linux distributions (userdel.c)
- PASS_MAX is now 127 (not 8) for Linux (getpass.c)
- LOGIN_RETRIES, LOGIN_TIMEOUT, PASS_CHANGE_TRIES are no longer compiled in,
  can now be set in login.defs, old values are used as defaults (lmain.c)
- unique uid/gid selection now more robust (useradd.c, groupadd.c)
- UID_MIN, UID_MAX, GID_MIN, GID_MAX in login.defs (useradd.c, groupadd.c)
- CRACKLIB_DICTPATH no longer compiled in, can be set in login.defs (passwd.c)
- PASS_ALWAYS_WARN: warn about weak passwords even for root (passwd.c)
- PASS_MAX_LEN, check truncated passwords again (obscure.c)
- check for weak passwords too if previous password was empty (obscure.c)
- CHFN_RESTRICT: don't let users change their full names (chfn.c)
- Linux has getusershell(), use it (chsh.c)
- check if the new shell is executable by the user (chsh.c)
- sleep before printing "Login incorrect", not the other way around (lmain.c)
- don't be picky about utmp only if any of -rfh flags given (lmain.c)
- do "wheel group" more like BSD does (smain.c)
- use getlogin() in su (smain.c)
- UMASK from login.defs defaults to 077, not 0 (lmain.c, newusers.c)
- #undef HAS_ATRM for Linux until atrm can do what we need (config.h.linux)
- Linux has most commands in /usr/bin, not /bin (age.c, passwd.c, userdel.c)
- ULIMIT from login.defs works on systems using setrlimit() too (lmain.c)
- LOGIN_STRING should work now (pwauth.c, getdef.c)
- kludge to avoid conflict with Linux <shadow.h> (gshadow.h)
- mv Makefile Makefile.xenix ; mv config.h config.h.xenix - so that they are
  not lost when you copy the right ones to Makefile and config.h
