Raw Blame History

CHANGES from sudo 1.2 (unofficial version)
01) sudo now works under hpux, aix, sunos, bsd43, ultrix, linux, osf and irix.
02) Files w/o the executable bit will be ignored if they are in your PATH.
03) If execv() fails, perror is called (which prints out an error based on
errno) and sudo exits with -1.
04) Included in this shar should also be a version of getpass() derived from
the bsd net-2 source which works on bsd, ultrix, hpux, aix, and irix
at least. The latter three unixes have what i consider to be a broken
getpass() in that if /dev/tty can't be opened it doesn't just use stdin
like bsd getpass(). This means you cannot do: rsh host "sudo command"
and have it work if your ticket has expired.
05) The Makefile has changed significantly. It now has defines for all
supported architectures.
06) Changed MAXCOMMANDLENGTH from 48 bytes to MAXPATHLEN and included
sys/param.h where appropriate.
07) Rewrote the code that expands links & paths. It now works correctly.
(rewrote find_path.c)
08) Added a define NEED_STRDUP so we don't conflict with the system's strdup(3)
09) Now does *not* pass LD_* environmental vars on to programs that get
exec'd. Also removes SHLIB_PATH for hpux and _RLD_* for dec osf.
10) Now searches current dir last if '.' or '' are in PATH. Misses braindeath
like './' but if that's in your path you deserve all the trojans you get.
11) Added in linux patches from drew + flex support.
12) Added insults back in from original sudo(8) (define USE_INSULTS).
13) visudo now uses EDITOR envar (from John_Rouillard@dl5000.bc.edu)
14) you can now specify a dir containing commands that a sudoer can do.
(from John_Rouillard@dl5000.bc.edu)
15) Ported to Solaris 2.x (based on a port of sudo 1.1 done by UnixOps).
16) Took out setuid(0); setruid(uid); pairs that bracketed calls to
update_timestamp() since they are unnecesary and setruid() is
broken on systems without a setreuid(2) or setresuid(2) system call.
(Ie: AIX and Solaris 2.x).
17) The bulk of sudo now runs with the caller's real uid. Grep for
be_root() to find the exceptions.
CHANGES from sudo 1.3
18) Added SECURE_PATH as suggested by russells@ccu1.auckland.ac.nz.
19) Reworked clean_envp() to modify environ (not envp) so we can use
execvp() safely.
20) Now use execvp() instead of execve() so sudo /bin/kill works under
broken solaris. This also fixed sudo /etc/fastboot under stock
4.3 BSD. Basically, this means that any executable shell script that
lacks a '#!/bin/sh' magic number will now work with sudo. Personally
I think that the broken scripts should be fixed rather than changing
sudo, but vendors will be broken. Sigh.
21) Added USE_EXECV define so you can make sudo use execv() if you
want. Using execvp() shouldn't be a problem since it is always
handed a non-relative path that begins with '/' but some people
may not trust execvp().
22) Log file lines will no longer get truncated. Syslog entries that
would overrun the syslog(3) line limit are continued on another entry.
23) When logging to a log file, long entries are indented to improve
readability.
24) Whenever the umask is changed, it is changed back to what it was
before.
25) Log file is written as mode 600 instead of 644
26) Umask that sudo runs with may now be specified.
27) There is now a "configure" script.
28) Sudo will use ultra fast crypt (ufc) if it finds it for systems w/o
a real crypt(3) (non-US ConvexOs/Secure for instance).
29) _BSD_COMPAT is now defined for Irix.
30) The global variable uid is now initialized to -2 because I'm paranoid.
31) Native Solaris 2 port from Matthew.Stier@aisg.com
32) Now use sysconf(2) instead of getdtablesize(2) if it is available
(see change #31). Because of the the getdtablesize() emulation for
hpux is no longer necesary.
33) Now only do a getcwd(3) or getwd(3) once and do it as the real user.
Sudo should no longer complain that it can't get the cwd unless
there is a real problem.
34) Changed some malloc'd globals of fixed length to be allocated from
the stack instead as there was no win in allocating them from the
heap.
35) Fixed AIX STATIC_FLAGS as per the AIX faq.
36) Added -V flag to sudo and visudo (for version)
37) Now treat EACCESS like EPERM when doing stat(2) in find_path.c
38) Added prototypes for sudo functions (via __P macro)
39) configure now uses uname(1) if it exists
40) gethostbyname(3) is now only called if you define FQDN. There's really
no reason to not trust gethostname(2) and this way if name service is
hosed sudo isn't...
41) added -v (validate) flag to sudo to update a timestamp w/o running
a command
42) now use tgetpass() (getpass with a timeout)
43) find_path() now uses realpath(3)
44) wrote versions of realpath(3) and getcwd(3) for those without
45) wrote tgetpass()--a getpass() that times out via select(2)
46) sudo now uses posix signals if available
47) Finally added ConvexOS C2 security support from
"Peter A. Nikitser, Systems Software Support, QUT" <P.NIKITSER@qut.edu.au>
48) You can now #undef MAILER if you don't run sendmail or the equivalent.
49) AFS support from adamh@austin.ibm.com
50) If you define BOTH_LOGS in sudo.h you can log both via syslog(3) *ans*
to a log file.
51) Added ultrix /etc/auth (enhanced security) support.
52) Sudo now will work with a 4.2BSD syslog (SunOS < 4 && ultrix).
Personally, I'd say you are better off logging to a file if
your syslog is this ancient.
53) Changed realpath(3) to sudo_realpath() since we need to do the
chdir(2) with the invoking uid. sudo_realpath() should be
faster than vendor-supplied realpath(3)'s anyway...
54) No longer create a static binary on AIX since it reportedly
causes problem on newer versions on AIX 3.x.
55) If sudo_realpath cannot chdir() back to cwd sudo will print
and error and exit. Previously it would either fail silently
or print an incorrect error message.
56) Moved code to send error mail to be after the log message.
From rouilj@cs.umb.edu.
57) Added SUDO_USER and SUDO_UID envars. Suggested by John P. Rouillard
(<rouilj@cs.umb.edu).
58) Added -k and -h options and rearranged some of the code to be
more modular and less braindamaged. This introduces the concept
of "run modes" to sudo.
59) Fixed visudo and flex. visudo now calls yyrestart() if you are using
flex instead of lex. From bostley@cs.colorado.edu.
60) Added a "cat page" for systems w/o nroff.
61) Fixed a bug whereby only the last directory specified in a Cmnd_Alias
was checked. Reported by "James R. Hendrick" <hendrick@ctron.com>.
62) All .{c,lex,yacc} files now include both sys/types.h and unistd.h so
we are sure to get the typedef of uid_t.
CHANGES from sudo 1.3.1
63) Added preliminary support for DEC OSF/1 protected passwords
(shadow passwords).
CHANGES from sudo 1.3.1pl1
64) More support for DEC OSF/1 protected passwords (shadow passwords).
CHANGES from sudo 1.3.1pl2
65) Fixed mail logging to include the username as it should have.
66) Added hostname to log message in error mail.
67) Added -l flag to sudo to list the allowed/forbidden commands.
Suggested by matthew@gateway.bsis.com (Matthew Stier)
68) Fixed bison warnings for parse.yacc and visudo.yacc.
Pointed out by alfie@dcs.warwick.ac.uk (Nick Holloway).
CHANGES from sudo 1.3.1pl3
69) Sudo will now exit with an error if the command to be run is > MAXPATHLEN.
70) Test in configure for termios support was insufficient. It thought
Nextstep 3.2 had termios just because it as termios.h (need to link
with -posix for termios on NeXT's)
CHANGES from sudo 1.3.1pl4
71) First stab at Skey support.
72) Sudo now sets IFS to be SPACE, TAB, NEWLINE.
73) Sudo now sets the real and effective gid to root's group
(based on passwd file).
74) Sudo now checks that the sudoers file is owned by a certain user
and not readable or writable by anyone else.
(based on a suggestion by Joerg Schumacher <schuma@ips.cs.tu-bs.de>)
75) Visudo now sets the owner on the new sudoers file based on #74
76) Sudo and visudo will now compile with byacc (Berkeley yacc).
77) If the rename(2) of stmp -> sudoers fails /bin/mv is executed before
bailing. Based on code from Case Larsen <clarsen@mh1.lbl.gov>.
78) User-level configuration is now done in options.h.
79) Moved all compatibility #defines to compat.h
80) Incorporated new parsing code from Chris Jepeway <jepeway@cs.utk.edu>.
This is much better than the previous parser.
81) Rewrote visudo.c and tickled parse.yacc to work with it. Visudo
now gives you options if a parse error occurs rather than blindly
dumping you back in the editor.
82) Took out all references to realpath since we are now checking based
in inode and device (with Chris' new parser). The upshot of this
is that path matches are done safely and the symlink problem has
gone away.
83) Fixed bison warnings from new parse.yacc.
84) Added a default case to parse.lex to error on unmatched tokens as Chris
sugggested.
85) Converted configure.in and acsite.m4 to autoconf 2.1.
86) Added lsearch.c and search.h for os's w/o lsearch()/lfind().
87) Sudo now checks to see that the file it is executing is a regular file
(was just checking the execute bit so dirs slipped through).
Pointed out by Barb Dijker <barb@labyrinth.com>.
88) Fixed a problem on HP-UX trusted systems with getpwuid() returning "*"
unless the real uid is 0. Reported by Brian Cunnie (cunnie@nyc.hp.com).
89) configure now checks for size_t and ssize_t in unistd.h as well
as sys/types.h.
90) configure now checks for egrep before actually using it.
91) configure now checks for a working void implementation (ie: void * as
a generic pointer) and sets VOID to void or char accordingly.
92) Added support for SunOS 4.x C2 security (shadow passwords) from
Kendall Libby (fubar@shore.net)
93) Changed all occurences of bzero() to memset() and bcopy() to
memmove().
94) Fixed a bug in sudo.c. If a user has no passwd entry sudo would
dump core (writing to a garbage pointer). Pointed out by
Stephen Schaefer <sps@gateway.bsis.com>.
95) Worked around a bug in AIX's lex in parse.c. AIX lex doesn't seem
to handle {x,y} range notation correctly. Bleah.
96) Sudo would not report a failed attempt if the user entered <return>
at the 2nd password: prompt so someone trying to guess a password
could just invoked sudo multiple times and try one passwd at a time.
Reported by Jonathan Adams <jonathan@smada.com>.
97) Added User_Alias facility.
98) Rewrote most of the ip address / network support. Now works on all
systems sudo has currently been tested on.
99) Sudo now sets SUDO_COMMAND and SUDO_GID envariables in addition to
SUDO_USER and SUDO_UID.
100) Added changes to configure.in for UnixWare.
(from John Warburton <jwarb@SACBH.com.au>)
101) Merged in changes for Interactive Unix and RISCos.
(from Andy Smith <abs@maunsell.co.uk>)
102) Added testsudoers (from Chris Jepeway <jepeway@cs.utk.edu>).
103) Added fix for parse.yacc to avoid the kludge I was doing.
(from Chris Jepeway <jepeway@cs.utk.edu>)
104) Now remove the IFS envar if set instead of setting it to a "safe"
value to avoid problems with make and others.
105) Added FAST_MATCH option to check basenames of sudo command and
paths listed in sudoers file. If the basename doesn't match
then it is not a match. If the basename matches, then do
a stat to make sure it is a valid match.
106) Now only stat(2) cmnd once in path_matches() (in parse.c). Sudo
was stating cmnd for *every* attempted match. Now the stat struct
is cached (ie: the var is a static).
107) Signal handlers in visudo are now only installed after the stmp
file is opened. Previously, it was possible to erase an open
stmp file by sending visudo a signal within a small window.
108) Added Goon Show insults from Russell Street <r.street@auckland.ac.nz>.
109) Broke out the insults into separate include files (insults.h
is the master and includes the appropriate one).
110) Now use getwd() instead of getcwd() and provide emulation for
OS's w/o it. This was done since some OS's with getwd()
implement getcwd() via a pipe to pwd(1). By emulating getwd()
by calling getcwd() on OS's w/o getwd() we lose nothing since
the compiler should optimize away the extra function call.
111) Added crypt() for DEC OSF/1 3.x enhanced security.
From "Richard L Jackson Jr" <rjackson@osf1.gmu.edu>.
112) Added an option to run the command in the background (-b) as
suggested by Jonathan Adams <jonathan@smada.com>
113) First stab at kerberos support. I'm not really sure it is
possible to do this in a sane manor. Sigh.
114) Better kerberos support. Had to use setreuid(2) but falls
back on a kludge if that does not exist or is broken.
115) Added -p (password prompt) support.
Suggested by "David W. Cooley" <dwcooley@COLBY.EDU>
116) Added partial implementation of -l (list) flag.
This is probably as good as it will get until sudo:tng.
117) Added anti-spoofing code to tighten up a race condition
where a user could run sudo some_link and then change
where the link pointed after the old link had been
validated but before the exec().
118) Now update timestamp file via utime() (and emulate via utimes()
if necesary) to eliminate a small race. Works with
both POSIX utime() as well as old utime() in BSD <= 4.3.
119) Kerberos ticket file now lives in same dirs as sudo timestamp
files (to avoid trouncing on normal ticket file) and is removed
after validation.
120) Now log tty user is on as well as pwd in sudo logs.
CHANGES from sudo 1.3.2 BETA
121) Fixed a bug in the anti-spoofing check.
122) Fixed up ISC support so that it works and looks like non-streams
stuff in interfaces.c.
123) Now deal correctly with ip implementations that has an sa_len
field in struct sockaddr.
124) Check ownership and permissions on timestamp dir and ignore if
not owned by root and mode 0700. Problem pointed out by Larry Auton
<lda@research.AT&T.com> and Navjot Singh <singh@research.AT&T.com>.
125) Ignore timestamp files with preposterous dates to keep people from
faking out sudo on OS's that allow you to give away files to root.
Problem pointed out by Larry Auton <lda@research.AT&T.com> and
Navjot Singh <singh@research.AT&T.com>.
126) A timeout of 0 will now cause a password to be entered every
time. Based on a suggestion by Larry Auton <lda@research.AT&T.com>
and Navjot Singh <singh@research.AT&T.com>.
CHANGES from sudo 1.3.3 BETA
127) Cleaned up interfaces.c so that it is more readable.
128) Added support for syslog()'s that don't guarantee delivery
of a message. HP-UX is the only known offender.
129) No longer use memmove() since memcpy() does what we need and
configure doesn't always catch memmove() even when it is
there (may be a library problem).
130) Updated man page to reflect two more security issues.
131) Cleaned up shadow password support in check.c. It should now
be readable.
132) Added SCO support.
133) Added check to configure to find the max length of a uid_t
in characters.
134) Removed uid2str() since we now know how big a uid_t/gid_t
can be. This elminates a few malloc()'s.
135) Added support for multiple insult types. Based on code and
a suggestion from Dieter Dworkin Muller <dworkin@village.org>.
136) Replaced clean_env() and rmenv() with a rewritten clean_env()
that should be a little faster. This also makes it easier to
add to the list of "dangerous" envariables.
137) Added netgroup support. Netgroups must start with a leading
"+" to that sudo knows it is a netgroup.
138) Split out sudoers file format into its own man page.
As suggested by Andy Smith <abs@maunsell.co.uk>.
139) Updated testsudoers.c to grok netgroups.
CHANGES from sudo 1.3.4 BETA
140) Added SecurID support from Giles Todd <giles@gt.demon.co.uk>.
141) Added -s flag to start a root shell and -- to signify end of args.
142) Sped up logging routines by replacing strncpy()'s with strcat()'s.
This is safe because we dyanically allocate logline to be big enough.
143) Now support command line arguments in the sudoers file.
144) Sped up the loading on command line arguments. This fixes the
"commands with large argc's take forever to run" bug.
145) Expanded MAXCOMMANDLEN to 8K since we now have to deal with
command line arguments. Added bounds checking in fill() and
append() so we don't drop core.
XXX - 8k makes sudo *SLOW*
146) Added support in the lexer for "termination characters" to be
escaped. Ie: you can now use [\,:=] in command line args
as long as you escape with a \.
147) Testsudoers can now deal with commands that have arguments.
148) If a file is not executable or not a regular file sudo will
now give the appropriate error message instead of just
"command not found" which is misleading.
149) Fixed a bug where if FQDN is set, load_interfaces() was never
called.
150) tty is now a global so it can be used in the ticket file
at a later date.
151) Strings in the parser are now allocated dynamically. This results
in a large speedup as compared to a 1K array on the stack. I
have freed the strings in the parser where appropriate but that
may not catch all instances. Even so, the average sudo now
takes up less memory than the 1K array version.
152) Fixed a bug in tgetpass() and configure that broke termio/termios
support for some OS's.
153) Added cheapo implementation of tty-based timestamps. The correct
way is to have username be a directory with the tty tickets
inside. However, the current code does not take to that very
well, and it does not allow the two systems to coexist. Therefore,
instead of timestampdir/user/tty it is timestampdir/user.tty.
154) Added support for building in other than the source directory.
Based on changes from "Simon J. Gerraty" <sjg@frodo.dn.itg.telecom.com.au>
155) options.h and pathnames.h are now included via angle brackets
(<>) so as to use the -I include path. This way, those using
a shadow build tree may have local copies of these headers
w/o clobbering the distribution ones.
156) EXEMPTGROUP is now a string (group name) and user_is_exempt()
is now less of a hack. It uses getgrnam(EXEMPTGROUP) to
get a list of users in the exempted group.
157) --prefix and --exe_prefix are now honored in the Makefile.
158) Sudo will now behave reasonably in the case where the sudoers
file location is mounted via NFS and the client does not
have "root" NFS privs.
159) _PATH_SUDO_SUDOERS, _PATH_SUDO_STMP, and SUDOERS_OWNER are
now set via the Makefile since that appears to be what
most people expect...
160) Now include a pre-generated version of parse.lex since so many
versions of lex are brain damaged. If parse.lex is changed
a new lex.yy.c will be generated. The distribution copy is
sudo-lex.yy.c.
161) Upgraded to GNU autoconf version 1.5. There are now even
*more* options.
CHANGES from sudo 1.3.5 BETA
162) Fixed S/Key support.
163) Cleaned up shadow password support further by moving much of
it to getspwuid.c.
164) First cut at DCE support. [needs work to be functional]
165) New Digital UNIX C2 support based on code from
"Randy M. Hayman" <haymanr@icefog.sois.alaska.edu>
166) S/key support now works with the generic bellcore s/key
as well as the s/key from Wietse Venema's logdaemon.
(Previously only worked with the logdaemon s/key).
As an added bonus the s/key challenge is now embedded
in the password prompt for a cleaner look.
167) lsearch.c will now compile on a strict ANSI C compiler.
ANSI doesn't allow pointer arithmetic on a "void *"
but gcc does.
168) Bought back latest HP-UX DCE support from Jeff Earickson
<jaearick@colby.edu>.
169) configure now comletely groks $SUDO_LIBS and $VISUDO_LIBS.
Plain old $LIBS is no longer used. LDFLAGS has also been
split up into $SUDO_LDFLAGS and $VISUDO_LDFLAGS.
The reason for this is that sudo often needs extra libs
for alternate authentication schemes but visudo rarely does.
170) The code to copy command arguments flaied for large values of
argc due to realloc() lossage. We now cheat and treat argv[]
as a flat string (since that's what it is) and use pointer
arithmetic to compute the length. Kind of sneaky but it
works (and is relatively fast).
CHANGES from sudo 1.3.6 BETA
171) Added support for UN*X groups in sudoers based on code from
Dougal Scott <dwagon@aaii.oz.au>.
172) interfaces.c should work on ISC UN*X again.
173) All source files are <= 14 characters for old SYSV filesystems.
CHANGES from sudo 1.3.7 GAMMA
174) Minor configure[.in] fixes.
175) tgetpass.c now compiles on OS's that put the definition of
fd_set in <sys/bsdtypes.h>
CHANGES from sudo 1.4
176) Command args in sudoers are now stored in an argument vector
instead of a flat string to make wildcard matching simpler.
177) Added NewArgv and NewArgc that describe the command to be
executed. The copy of args in cmnd_args is no longer necesary
and has been removed.
178) Using strcmp(3) for argument matching in command_matches()
(was path_matches()) is no longer sufficient since we don't
have a flat string. compare_args() is used instead which
calls either strcmp(3) or wildmat(3l) depending on whether
there are shell-style meta chars (wildcards) present.
179) Shell-style wildcard matches are now available in the sudoers
file. Matches are done via Rich $alz's wildmat(3).
This required the tweaks described in #176-178 as well as
other, more minor, changes.
180) Commented out rule to build lex.yy.c from parse.lex since
we ship with a pre-flex'd parser and can't rely on file
dates being set correctly.
181) Fixed visudo and testsudoers to deal with new argument
vector handling.
182) A null string ("") as shell in passwd file (or $SHELL) is
now treated as the bourne shell.
183) Converted *.man to pod format for easy conversion to man,
html, latex, and just plain text. Tried to make the
sudoers manual easier to read in the process.
184) Updated sample.sudoers and sudoers.pod to include info
on wildcards.
CHANGES from sudo 1.4.1
185) compat.h now defines _PASSWD_LEN based on PASS_MAX if it
is defined (from limits.h on SYSV).
186) Both short and long hostnames may now be used in the sudoers
file if FQDN is defined. From patches submitted by
Michael Meskes <meskes@Informatik.RWTH-Aachen.DE>.
187) Now use skeylookup() instead of skeychallenge(). Hopefully
this will work around a problem some people have reported
on Solaris 2.5 with sudo and logdaemon 5.0's skey.
188) Now uses /var/run to hold timestamp files if it exists. This
is more secure.
189) configure now puts the timestamp dir in /var/run if it exists.
Sugestion by Michael Meskes <meskes@Informatik.RWTH-Aachen.DE>.
190) Both short and long hostnames now exist even if FQDN is not set.
This allows machines with fully qualified hostnames set via
hostname(1) to use them in the sudoers file.
191) sudo was not honoring "." in $PATH due to a bug in find_path().
192) Added IGNORE_DOT_PATH option to ignore "." in $PATH.
193) tgetpass() now uses raw read(2) and write(2) instead of stdio.
This should make it work on more OS's. Previously, it used
stdio (buffered) fgets(3) and fputs(3) with select(2) which
may not be legal. Also got rid of the nasty goto's and
generally simplified the code.
194) Parser now supports hostnames like UPPERCASE.foo.com. Previously,
`UPPERCASE' was interpreted as an Alias. This means that
the `fqdn' stuff has been moved to the lexer (FQHOST is used
to avoid collision with FQDN option).
195) Reworked --with-FOO in configure.in to support --without-FOO.
Made shadow passwords the default for appropriate OS's. They
can be turned off with --without-C2.
196) Added NO_PASSWD option for those who don't want to be bothered
by a password prompt from sudo. This is really just a hack.
197) Added support for double quotes to mean "treat these words as one
argument". This is similar to what most shells do.
198) Added mkinstalldirs to make install destination dirs if
they do not already exist.
CHANGES from sudo 1.4.2
199) Added support for --with-CC (which C compiler to use).
200) Added support for NOPASSWD token and running commands a
specified users (sudo -u) from Keith Garry Boyce
<garp@opustel.com>
201) Only link with -lshadow for Linux if libc lacks getspnam(). Problem
pointed out by Michael Meskes <meskes@Informatik.RWTH-Aachen.DE>.
202) Replaced SUDOERS_OWNER with SUDOERS_UID and SUDOERS_GID. Added
SUDOERS_MODE and changed the default to 0440 (from 0400).
It is now possible to NFS-mount sudoers without doing anything fancy.
202) If a runas list is specified, a user may only run commands as
"root" if "root" is a member of the runas list. The old behavior
was to always allow commands to be run as root, even if a runas
list was specified. Now you can give someone "sudo -u operator"
and not have the equivalent of "sudo -u root" as well.
203) Added "USER=%s" to logging functions.
204) configure will now add -lPW to (VI)?SUDO_LIBS if using bison
or DCE and alloca(3) is not in libc (or provided by gcc) but
is in libPW.a.
205) sudo would give an incorrect error message if the sudoers file
didn't exist due to close() stomping errno if the open() failed.
206) Fixed "shell" mode (sudo -s). When building NewArgv sudo was
not allocating space for the NULL.
207) Added support for wildcards in the pathname. Ie: /bin/*.
208) 'command ""' in sudoers now means no args allowed.
209) Added command line args to SUDO_COMMAND envariable.
210) HP-UX 10.x with C2 now uses bigcrypt().
Changes from david_dill@Merck.Com (David Dill).
211) lsearch.c will now compile w/o compiler warnings.
(Updated from NetBSD lsearch.c)
212) Now uses POSIX fnmatch(3) (which uses ! instead of ^ in ranges)
CHANGES from sudo 1.4.3
213) Now allows network/netmask in sudoers to override per-interface
netmask.
214) Fixed -u support with multiple user lists on a line.
215) Fixed a core dump problem when built with -DSHELL_IF_NO_ARGS.
216) Fixed 2 typos in parse.yacc and removed some unnecesary if's.
217) Now always use install-sh since SunOS install can't do uid/gid's.
Other BSD installs are probably similarly afflicted.
218) Fixed NFS-mounted sudoers file under solaris both uid *and* gid
were being set to -2. Now set uid to 1 to avoid group being
remapped.
219) Now includes alloca.c (from gcc) for those w/o it. Linking
against -lPW breaks visudo on HP-UX and probably others.
220) Added --with-libpath, --with-libraries, --with-incpath options
to configure.
221) configure now uses shicc instead of gcc on BSD/OS >= 2.0 to
generate binaries linked with shared libs.
222) The parser was setting no_passwd even if there wasn't a
runas match. I reordered some things in parse.yacc
to fix this.
223) `sudo -v' (validate) wasn't paying attention to NOPASSWD.
Now it does.
224) testsudoers now groks "-u user".
225) Updated AFS support based on what tcsh 6.06 does.
226) Fixed a typo/thinko that broke BSD > 4.3reno wrt interfaces.c.
227) Hpux10 shadow password stuff now uses SecureWare routines.
228) SecureWare passwd checking now uses bigcrypt() if available.
Now uses AUTH_MAX_PASSWD_LENGTH if defined.
229) configure now makes sure you don't have a config.cache file
from another OS.
230) Added better shadow password detection.
BSD >= 4.3reno -> /etc/master.passwd
hpux9: getspwnam() -> /.secure/etc/passwd
hpux10: getspnam() or getprpwnam() -> /tcb/files/auth/*/* (link with -lsec)
SVR4: getspnam() -> /etc/shadow
solaris: getspnam() -> /etc/shadow
irix[56].x: getspnam() -> /etc/shadow
sunos 4.x: getpwanam() -> /etc/security/passwd.adjunct
DUNIX: getprpwnam() -> /tcb/files/auth/*/* (link with -lsecurity)
SecureWare: getprpwnam() -> /tcb/files/auth/*/*
ultrix 4.x: getauthuid() -> /etc/auth.{pag,dir}
231) '(' in command args no longer are a syntax error.
232) '!command' now works in the presence of a runas or NOPASSWD token.
Simplified parse rules wrt runas and NOPASSWD (more consistent).
233) Command args and now compared as a flat string again. This makes
wildcard matches more consistent.
234) DUNIX C2 support now groks AUTH_CRYPT_OLDCRYPT and AUTH_CRYPT_C1CRYPT.
235) configure now uses config.{sub,guess} to guess OS type.
Sudo should work out of the box on more OS's now.
236) Got rid of HAVE_C2_SECURITY, now just use SHADOW_TYPE.
237) Fixed race in tgetpass() where echo can be turned off and
left off if sudo is used in a pipeline and a password is
required.
CHANGES from sudo 1.4.4
238) `sudo -l' output now includes runas and NOPASSWD info and
asks for a password unless NOPASSWD for ALL is set.
239) Sudo can now deal with all-caps user and host names.
240) Sudo will now remove the "ENV" and "BASH_ENV" envariables.
From Michael Meskes <meskes@Informatik.RWTH-Aachen.DE>.
241) `sudo -l' will now expand Cmnd_Alias's (could be prettier).
242) `sudo -s' will now set $HOME to root's homedir (or that of
the user specified -u) so dot files get sourced.
CHANGES from sudo 1.4.5
243) $HOME was always being set, not just with `-s'.
244) In visudo, the owner and group of the sudoers file were
being set too early; an editor could change them and change
the owner/group of the resulting sudoers file.
CHANGES from sudo 1.5
245) Added SHELL_SETS_HOME option.
246) Added NO_MESSAGE option.
247) Added %u and %h escapes in PASSPROMPT to expand to user's name
and host.
248) Added "SUDO_PROMPT" envariable.
249) Usernames may now begin with a digit. Gross, but people do it.
Sudo 1.5.1 released.
250) Added `opie' support.
251) Added check to make sure fnmatch() really works.
252) Now use the prompt S/Key gives us instead of rolling our own.
253) Added -H flag from Danny Barron <dcbarro@nppd.com>.
254) Add SUDO_PS1 envariable support.
255) Attempt at sequent support.
Sudo 1.5.2 released.
256) visudo acts sanely when there is no sudoers file.
257) Added Runas_Alias support.
258) Sudo will now work with SUDOERS_MODE == 400 and SUDO_UID = 0.
259) Alias's in a runas list are now expanded.
260) Fixed bug with > 32 saved aliases. Reported by BHH@capgroup.com.
261) Code that uses sprintf() is now more paraniod about buffer
overflows.
262) Whitespace is now allowed after a line continuation character before
a newline in sudoers.
263) %h in MAILSUBJECT expands to local hostname.
Sudo 1.5.3 released.
