e9914a91b1 The sudoers plugin now defines its own list of debugging subsystem names 
and defines.

866cfc4fc3 Add support for multiple Debug lines per program. Callers may 
register arbitrary debug facilities or use built-in defaults.  We
now use separate Debug statements for plugins and programs.

2d61d38c23 Add sudo_ prefix to alloc.c functions and rename alloc.h -> sudo_alloc.h 2014-06-27 10:48:31 -06:00

aecef4aa1d Rename warning/fatal -> sudo_warn/sudo_fatal to avoid namespace 
pollution in libsudo_util.so.

088edcb6f5 Add exported libsudo_util functions to util.exp and mark in headers 
using __dso_public.

218aa1e598 Move the sha2 code into libreplace and add configure checks for 
SHA224Update in libc and libmd.  Solaris uses "void *" where we use
"unsigned char *" so we need a check for that too.  Solaris sha2.h
defines SHA224, SHA256, SHA384, and SHA512 so rename those tokens.
Adapted from changes from Vladimir Marek in bug #641.

27aff732f1 Fix matching of uids and gids broken in sudo 1.8.9. 2014-04-09 10:22:09 -06:00

9ff3b1b570 Make hexchar() return -1 on invalid input instead of calling fatalx(). 
Callers used to check that the string was hex before calling hexchar().
Now callers must check for a -1 return value instead.

8287e21d36 Add use_netgroups sudoers option. For LDAP-based sudoers, netgroup 
support requires an expensive substring match on the server.  If
netgroups are not needed, this option can be disabled to reduce the
load on the LDAP server.

878ddb1788 Use atoid() instead of atoi() when parsing uids/gids so we get 
proper range checking.

96eb2c4f8f Add warning_gettext() wrapper function that changes to the user locale, 
then calls gettext().
Add U_ macro that calls warning_gettext() instead of gettext().
Rename warning2()/error2() back to warning_nodebug()/error_nodebug().

b38d253e98 Add "headless" tail queues and use them in place of the semi-circular 
lists in sudoers.  Once the headless tail queue is built up it is
converted to a normal TAILQ.  This removes the last consumer of
list.c and list.h so those can now be removed.

d0e3867587 Add limited support for "sudo -l -h other_host". Since group lookups 
are done on the local host, rules that use group membership may be
incorrect if the group database is not synchronized between hosts.

ab61c02546 Replace sequence number-based cycle detection in visudo with a 
"used" flag in struct alias.  The caller is required to call
alias_put() when it is done with the alias.  Inspired by a patch
from Daniel Kopecek.

ddc1d36a0b RHEL (and perhaps other Linux distros) use the string "(none)" 
instead of an empty string when there is no actual NIS-style domain
name.  Bug #596

Todd C. Miller
1d7072fe09 Don't include <sys/param.h>. We only needed it for MAXPATHLEN, 
MAXHOSTNAMELEN and the MIN/MAX macros.  We now use PATH_MAX and
HOST_NAME_MAX throughout without falling back on MAXPATHLEN or
MAXHOSTNAMELEN and define our own MIN/MAX macros as needed.
 2012-12-04 10:40:47 -05:00

3c9da162e4 Use MAX_HOST_NAME+1 (limits.h) instead of MAXHOSTNAMELEN (sys/param.h 
or netdb.h).

6a25affb47 Add rudimentary support for name-based matching as a compile-time 
option.  This unsafe when used in conjunction with the '!' operator.

57699c5531 If a command matches using an empty Runas_List (i.e. Runas_List is 
present but empty) and the -u option was not specified, set runas_pw
to user_pw instead of using runas_default.  This is intended to be
used in conjunction with the Solaris Privilege Set support for rules
that grant privileges without changing the user.
 2012-08-02 14:37:32 -04:00

e2d210a340 Add support for parsing an empty Runas_List, which only allows the 
command to be run as the invoking user.  This can be used in
conjunction with the Solaris Privilege Set support to grant privileges
without changing the user.

0d108287b9 Do not use GLOB_BRACE or GLOB_TILDE flags to glob()--we want the

c4ba511613 Do not include GLOB_MARK in the flags we pass to glob(3). Fixes a 
bug where a pattern like "/usr/*" include /usr/bin/ in the results,
which would be incorrectly be interpreted as if the sudoers file
had specified a directory.  From Vitezslav Cizek.

09beba8259 Revert 003bdb078a15. We need to #include <gram.h> not "gram.h" and 
<def_data.h> and not "def_data.h" when generating the parser in a
build dir.

d9e807b269 If the user specifies a runas group via sudo's -g option that matches 
the runas user's group in the passwd database and that group is not
denied in the Runas_Spec, allow it.  Thus, if user root's gid in
/etc/passwd is 0, then "sudo -u root -g root id" is allow even if
no groups are present in the Runas_Spec.

092b4b4d02 Be careful not to deref user_stat if it is NULL. This cannot currently 
happen in sudo but might in other programs using the parser.
