Edited setpwnam.c somewhat to - improve error checking, beautify the code, and remove output - to stderr. - Fixed a couple of buffer overrun nits in passwd.c, patches from - David Holland. - -Version 1.21b (23-Jan-97): - Shutdown now supports a message on the command line, a'la - "shutdown -f +5 'for some reason'" - -Version 1.20 (2-Nov-96): - Fix by Steffen Zahn <zahn@berlin.snafu.de> for shutdown.c so it - prints its final message. - -Version 1.19 (8-Jul-96): - Fix by faith@cs.unc.edu to allow C-A-D after halting in shutdown.c - -Version 1.18 (19-Nov-95): - passwd almost completely rewritten by Martin Schulze - <joey@infodrom.north.de> to use setpwnam() and support - more long options. There's a new man-page as well. - Hacked some more on Martins passwd.c to support -s and -f options. - The old passwd.c is in the Attic/ sub-directory. - Bugfix in shutdown.c to fix file modes. - -Version 1.17 (7-Oct-95): - Added setrlimit() calls to passwd.c and chsh.c to fix security hole - caused by resource limitations. Inspired by Zefram - <A.Main@dcs.warwick.ac.uk>. Also beefed up the ptmp locking in - chsh.c. - Added swap_off() function to shutdown.c by baekgrd@ibm.net - (Anders Baekgaard). - Bugfix in shutdown.c that makes sure wtmp gets closed. By - Alexandre Julliard <julliard@sunsite.unc.edu>. - Fixed bug in passwd.c that made it impossible to change from having - no password into having one. - -Version 1.16 (18-Sep-95): - Added feature to passwd.c by Arpad Magossanyi (mag@tas.vein.hu), - so root can give a password for a user on the command line. This - might be useful in a shell script autogenerating passwords for - new users. - - Added and updated manual pages for all commands by Rick Faith. - -Version 1.15d (21-Aug-95): - Fixed minor nit with salt generation in passwd.c - By Steven Reisman <sar@beehive.mn.org>. - -Version 1.15c (5-Jul-95): - passwd does not allow reuse of the old password when changing. - passwd returns 1 if the password is not changed. This was - suggested by Anibal Jodorcovsky <anibal@ee.mcgill.ca> who - also fixed my initial bug in this feature. - - passwd uses O_EXCL for opening /etc/ptmp instead of access/fopen. - This was suggested by jorge@un1.satlink.com (Jorge). - -Version 1.15a (12-Jun-95): - Fix in last.c so it does not print wtmp entries marked DEAD_PROCESS. - By Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> - -Version 1.15 (5-Jun-95): - Man-page fixes, fixes in pathnames.h to adhere to the FSSTND. - Fix by Rickard Faith <faith@cs.unc.edu> to passwd.c, so sanity - checks come before the second entry of the new password. - This is for Linux 1.2, GCC 2.6.2 or later. - -Version 1.14a (12-Mar-95): - Fixed passwd and chsh so a username that is a prefix of another - doesn't affect the other's password. After suggested patch - by Valtteri J. Karu <vatekaru@tuug.utu.fi>, but differently! - -Version 1.14 (12-Feb-95): - Added options -l, -y, -i to last.c. See last.man - -Version 1.13d (26-Jan-95): - Added some comments on request from Rik Faith. Compiled succesfully - on Linux 1.1.73, GCC 2.5.8, libc 4.5.26 - -Version 1.13c (6-Dec-94): - New versions of passwd and chsh due to Alvaro Martinez Echevarria - <alvaro@enano.etsit.upm.es>, so they will coexist with YP/NIS - passwords. - -Version 1.13b (7-Nov-94): - Use fgets() + atoi() in chsh.c instead of scanf(). - -Version 1.12 (17-Sep-94): - Rik Faith provided patches for passwd.c to let non-alphabetics count - as digits as well, allows more obscure passwords. - - Applied patches from Dave Gentzel <gentzel@nova.enet.dec.com> - to prevent dereferencing a NULL pointer, and turn off accounting - in shutdown.c - -Version 1.11 (18-Aug-94): - Finally got around to making it a non-alpha version. Just a - little cleanup in Makefile - -Version 1.10b (8-Jun-94): - David A. Holland <dholland@husc.harvard.edu> made me aware of a - security leak in passwd and chsh. /etc/ptmp could be forced to - be world-writeable. Fixed by hardwiring an umask of 022 into - passwd and chsh. - - Vesa Ruokonen <ruokonen@taivas.lut.fi> sent me a new pathnames.h - file that shouldn't conflict with paths.h. - - Cleaned the source a bit for -Wall - -Version 1.10a (31-May-94): - Vesa Ruokonen <ruokonen@taivas.lut.fi> provided a patch for - passwd.c such that it will work for multiple usernames for - the same uid. I mimicked his actions on chsh.c. In both cases - I added a check to ensure that even if utmp is hacked, one can - only change the password for users with the same uid. - -Version 1.9 (9-Feb-94): - Vesa Ruokonen suggested that newgrp should support passwords in - /etc/group. It now does. I mostly rewrote newgrp to make it - cleaner. - -Version 1.8 (19-Jan-94): - Rik Faith provided several patches, especially for passwd.c and - some man-pages. - -Version 1.7 (3-Nov-93): changes since 1.6 - Shutdown can now be used as a login shell. I forget who sent me the - patch. Example /etc/passwd entry: - - shutdown:dLbVbIMx7bVHw:0:0:Stopper:/:/etc/halt - - The package should now be prepared to have shutdown in /sbin as well - as in /etc. utmp and wtmp are allowed in /usr/adm too. Both things - are configurable in the Makefile. - - <flebbe@cygnus.tat.physik.uni-tuebingen.de> Olaf Flebbe provided a - patch for chsh.c to make it work. - - This version is built under linux 0.99.13 with gcc 2.4.3 and - libc 4.4.1 - -Version 1.6 (1-Jun-93) - Shutdown now looks more like shutdown on SunOS, but not quite. Most - of this was done by Scott Telford (s.telford@ed.ac.uk), but I - butchered his patches somewhat. This version was built under Linux - 0.99.9 with GCC 2.3.3 and libc 4.3.3. - - "make install" will now install shutdown in /etc instead of /usr/bin - -Version 1.5 (13-Dec-92) - This version is tested and built under Linux 0.98P6 with gcc-2.2.2d7 - You will have a hard time making it work with the older compilers and - libraries. - - Su is now deprecated. I believe that the GNU/FSF version is better. - -CONTENTS. -last - A new and better last command, a port from BSD done by - Michael Haardt. - I put a couple of if's in so LOGIN_PROCESS entries in wtmp - are not printed. - -chsh - CHangeSHell changes the shell entry in the passwd file. - Written from scratch by me. - -passwd - Changes the password in the passwd file. - Also done from scratch by me. - -su - A su(1) command by me. - -newgrp - Sets the gid if possible, ala su(1), written by Michael - Haardt. - -shutdown - Shuts down linux. Supports timed shutdowns, and sends - warnings to all users currently logged in. It then - kills all processes and unmounts file-systems etc. - - Shutdown also doubles as halt and reboot commands. - - Shutdown leaves the file /etc/nologin behind after shutdown, - it is wise to have a "rm -f /etc/nologin" in ones /etc/rc - - Shutdown now supports a -s switch, that works in connection - with the init program in poeigl-1.7 or later, so a singleuser - reboot is possible. - - Rick Sladkey <jrs@world.std.com> provided patches for better - umounting code, needed in connection with NFS. - - Remy Card <card@masi.ibp.fr> provided patches for support for - fastboot/fasthalt. These create a /fastboot file on shutdown, - and /etc/rc may check for the existance of this file, to - optionally skip fsck. - -example.rc An example of an /etc/rc file. Edit it to suit your own setup. - -ctrlaltdel - Sets the behaviour of the Ctrl-Alt-Del combination. - "ctrlaltdel hard" makes the key-combination instantly reboot - the machine without syncing the disk or anything. This may - very well corrupt the data on the disk. - - "ctrlaltdel soft" makes the key-combination send a SIGINT to - the init process. Such a command would typically be in /etc/rc. - For this to make sense you must run the init from the - poeigl-1.4 package or later. The System V compatible init in - this package won't reboot the machine when it gets a SIGINT. - Linux version 0.96b-PL1 or later is also needed for this - feature to work. - -init is gone as of V1.5, it was outdated and buggy. If you want a -SYSV compatible init get the newest one from Mike Smoorenburg, called -sysvinit.tar.Z - -INSTALLATION. -Simply do a - - make - -and then (optionally) as root: - - make install - - - - Peter (poe@daimi.aau.dk) diff --git a/login-utils/chfn.c b/login-utils/chfn.c index e25212e88..7c6bfac05 100644 --- a/login-utils/chfn.c +++ b/login-utils/chfn.c @@ -221,7 +221,7 @@ static boolean parse_argv (argc, argv, pinfo) info_given = false; while (true) { c = getopt_long (argc, argv, "f:r:p:h:o:uv", long_options, &index); - if (c == EOF) break; + if (c == -1) break; /* version? output version and exit. */ if (c == 'v') { printf ("%s\n", util_linux_version); diff --git a/login-utils/chsh.c b/login-utils/chsh.c index 4be7e555f..ce8c2ae90 100644 --- a/login-utils/chsh.c +++ b/login-utils/chsh.c @@ -217,7 +217,7 @@ parse_argv (int argc, char *argv[], struct sinfo *pinfo) { while (c != EOF) { c = getopt_long (argc, argv, "s:luv", long_options, &index); switch (c) { - case EOF: + case -1: break; case 'v': printf ("%s\n", util_linux_version); diff --git a/login-utils/last.c b/login-utils/last.c index 8d3a8911a..6d0ce2ff6 100644 --- a/login-utils/last.c +++ b/login-utils/last.c @@ -113,7 +113,7 @@ main(int argc, char **argv) { bindtextdomain(PACKAGE, LOCALEDIR); textdomain(PACKAGE); - while ((ch = getopt(argc, argv, "0123456789yli:f:h:t:")) != EOF) + while ((ch = getopt(argc, argv, "0123456789yli:f:h:t:")) != -1) switch((char)ch) { case '0': case '1': case '2': case '3': case '4': case '5': case '6': case '7': case '8': case '9': diff --git a/login-utils/login.c b/login-utils/login.c index c38abe442..048316bcc 100644 --- a/login-utils/login.c +++ b/login-utils/login.c @@ -390,7 +390,7 @@ main(int argc, char **argv) fflag = hflag = pflag = 0; passwd_req = 1; - while ((ch = getopt(argc, argv, "fh:p")) != EOF) + while ((ch = getopt(argc, argv, "fh:p")) != -1) switch (ch) { case 'f': fflag = 1; diff --git a/login-utils/mesg.c b/login-utils/mesg.c index 2b08d8350..a94ef6650 100644 --- a/login-utils/mesg.c +++ b/login-utils/mesg.c @@ -70,7 +70,7 @@ main(argc, argv) textdomain(PACKAGE); - while ((ch = getopt(argc, argv, "")) != EOF) + while ((ch = getopt(argc, argv, "")) != -1) switch (ch) { case '?': default: diff --git a/login-utils/passwd.c b/login-utils/passwd.c index cb50c0ef2..eb3303899 100644 --- a/login-utils/passwd.c +++ b/login-utils/passwd.c @@ -257,7 +257,8 @@ main(int argc, char *argv[]) { textdomain(PACKAGE); optind = 0; - while ( (c = getopt_long(argc, argv, "foqsvV", long_options, &opt_index)) != -1 ) { + while ((c = getopt_long(argc, argv, "foqsvV", + long_options, &opt_index)) != -1) { switch (c) { case 'f': fullname = 1; diff --git a/login-utils/wall.1 b/login-utils/wall.1 index 788f5f2b7..f774ebd54 100644 --- a/login-utils/wall.1 +++ b/login-utils/wall.1 @@ -53,6 +53,9 @@ Only the super-user can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies messages. +.Pp +Reading from a file is refused when the invoker is not superuser +and the program is suid or sgid. .Sh SEE ALSO .Xr mesg 1 , .Xr talk 1 , diff --git a/login-utils/wall.c b/login-utils/wall.c index 0bd3b79a9..2797f4651 100644 --- a/login-utils/wall.c +++ b/login-utils/wall.c @@ -91,7 +91,7 @@ main(int argc, char **argv) { if (p) progname = p+1; - while ((ch = getopt(argc, argv, "n")) != EOF) + while ((ch = getopt(argc, argv, "n")) != -1) switch (ch) { case 'n': /* undoc option for shutdown: suppress banner */ |
