1e9030d951 Move setting of FLAG_NO_CHECK into the if(pwflag) block. 
No change in behavior.

Todd C. Miller
a26c783bea Make pwcheck local to the pwflag block. 
Use pwcheck even if user didn't match since Defaults options may still apply.

7f0bb4b1a8 Make matching but negated commands/hosts/runas entries override a 
previous match as expected.  Also reduce some levels of indent by
a few placed continue statements.

879c46e4dd Add support for setting environment variables on the command line. 
This is only allowed if the setenv sudoers options is enabled or if
the command is prefixed with the SETENV tag.

f1a0953085 Fix printing of += and -= defaults. 2005-04-23 19:10:16 +00:00
Todd C. Miller
f261a99f22 In -l mode, only check local sudoers file if def_ignore_sudoers is not set 
and call LDAP versions from display_privs() and display_cmnd() instead
of directly from main().  Because of this we need to defer closing
the ldap connection until after -l processing has ocurred and we
must pass in the ldap pointer to display_privs() and display_cmnd().

9efe91fa1e Move initgroups() for -U option into display_privs() so group matching 
in sudoers works correctly.

terminal width.

5f06b19a6e Add -U option to use in conjunction with -l instead of -u. 
Add support for "sudo -l command" to test a specific command.

e605070143 Remove the FLAG_NOPASS, FLAG_NOEXEC and FLAG_MONITOR flags. Instead, 
we just set the approriate defaults variable.

0cddfc3684 Change an occurence of user_matches() -> runas_matches() missed previously 
runas_matches(), host_matches() and cmnd_matches() only really need to pass in
a list of members.  user_matches() still needs to pass in a passwd struct
because of "sudo -l"

2c3cff1704 Check def_authenticate, def_noexec and def_monitor when setting return flags. 
XXX May be better to just set the defaults directly and get rid of those flags.

2c2daa8eca Use: #include <config.h> 
Not: #include "config.h"
That way we get the correct config.h when build dir != src dir

541908f1bd A user can always list their own entries, even with -u. 
Better error message when failing to list another user's entries.
 2004-11-11 17:22:30 +00:00
Todd C. Miller
a239e60a6a The syntax to list another user's entries is now "-u otheruser -l". 
Only root or users with sudo "ALL" may list other user's entries.

5becc03851 Rewritten parser that converts sudoers into a set of data structures. 
This eliminates ordering issues and makes it possible to apply
sudoers Defaults entries before searching for the command.

1b06f3e81d Use glob(3) instead of fnmatch(3) for matching pathnames and stat each 
result that matches the basename of the user's command.  This makes
"cd /usr/bin ; sudo ./blah" work when sudoers allows /usr/bin/blah.
Fixes bug #143.

3c8145a923 No longer call it tracing, it is now "monitoring" which should be more 
a obvious name to non-hackers.

db2a97fd0a More scaffolding for dealing with multiple sudoers files: 
o init_parser() now takes a path used to populate the sudoers global
 o the sudoers global is used to print the correct file in yyerror()
 o when switching to a new sudoers file, perserve old file name and line number

4b75a03343 Rewind sudoers_fp in open_sudoers() instead of sudoers_lookup() so 
we start at the right file position when reading include files.

f30ab72c44 Add cmnd_base to struct sudo_user and set it in init_vars(). 
Add cmnd_stat to struct sudo_user and set it in sudo_goodpath().
No longer use gross statics in command_matches().
Also rename some variables for improved clarity.

1a46dd74f6 Don't pass user_cmnd and user_args to command_matches(), just use 
the globals there.  Since we keep state with statics anyway it is
misleading to pretend that passing in different cmnd and cmnd_args
will work.

98fb553875 Fix a bug introduced in rev. 1.149. When checking for pseudo-commands 
check for a '/' anywhere in cmnd, not just the first character.

8ce996770c Parse sudoers file as PERM_RUNAS not PERM_ROOT and remove a useless 
PERM_SUDOERS.  Restore to PERM_ROOT upon exit of the parse.

a6fe34784a When matching for "sudoedit" in sudoers check both the command the user 
typed *and* the command that is listed in the sudoers entry.

5150db1db3 In sudoers_lookup() return VALIDATE_NOT_OK if the runas user was 
explicitly denied and the command matched.  This fixes a long-standing
bug and makes:
    foo machine = (ALL) /usr/bin/blah
    foo machine = (!bar) /usr/bin/blah

equivalent to:
    foo machine = (ALL, !bar) /usr/bin/blah

6190f376c1 If the user specified a uid with the -u flag and the uid exists in 
the passwd file, set runas_user to the name, not the uid.

When comparing usernames in sudoers, if a name is really a uid (starts
with '#') compare it numerically to pw_uid.

4dc5700a6d Add a new flag, -e, that makes it possible to give users the ability 
to edit files with the editor of their choice as the invoking user,
not the runas user.  Temporary files are used for the actual edit
and the temp file is copied over the original after the editor is done.

7536a781f0 Add support for preloading a shared object containing a dummy execve() 
function that just sets error and returns -1.  This adds a
"noexec_file" option to load the filename as well as a "noexec" flag
to enable it unconditionally.  There is also a NOEXEC tag that can
be attached to specific commands and an EXEC tag to disable it.

02f37dc2da Add support for tuples in def_data.in; these are implemented as an 
enum type.  Currently there is only a single tuple enum but in the
future we may have one tuple enum per T_TUPLE entry in def_data.in.
Currently listpw, verifypw and lecture are tuples.  This avoids the
need to have two entries (one ival, one str) for pwflags and syslog
values.

lecture is now a tuple with the following values: never, once, always

We no longer use both an int and string entry for syslog facilities
and priorities.  Instead, there are logfac2str() and logpri2str()
functions that get used when we need to print the string values.
