6cbba7d665 Add an administrative domain to the passwd/group cache key for 
AIX which can have different name <-> ID mappings depending
on whether the database is local, LDAP, etc.

0b241088b3 There's no need to conditionalize the #include <unistd.h>, we require 
a POSIX system.

b727d4309c Handle sudo_get_grlist() returning NULL which can happen if 
getgrouplist() fails even after allocating the appropriate amount

59ab26dbcc Go back to a 2 args debug_decl and just use the "default" instance, 
now renamed "active".

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.

a78da37487 Make set_perms() and restore_perms() return an error instead of 
calling exit() on failure.

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().

0817429583 More sign compare fixes. On Solaris id_t is signed so use uid_t

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.

cab6b976dc For PERM_ROOT set egid to 0 so log files are not created with 
the gid of the user.

a0c53bd751 Call gettext inside log_error et al instead of having the caller do it. This way we can display any messages to the user in their own locale but log in the sudoers local. 2012-11-08 15:37:44 -05:00

649edc3192 Export group cache from sudoers.so for system_group.so to use. 2012-06-13 16:21:45 -04:00

0d82c4c7ee If sudoers_mode is group-readable but the actual sudoers file is 
not, open the file as uid 0, not uid 1.  This fixes a problem when
sudoers has a more restrictive mode than what sudo expects to find.
In older versions, sudo would silently chmod the file to add the
group-readable bit.

44ce5720de Remove the NO_EXIT flag to log_error() and add a log_fatal() function 
that exits and is marked no_return.  Fixes false positives from
static analyzers and is easier for humans to read too.

b49bb17c3e Better error messages, and added debugging throughout. 
Fixed seteuid() version of set_perms()/restore_perms().
Fixed logic bug in AIX version of restore_perms().
Added checks to avoid changing uid/gid when we don't have to.
Never set gid/uid state to -1, use the old value instead.

98486afbdf Add AIX-specific version of permission setting code to make sure 
that the saved uid gets restored properly.

e066ff5caf More complete fix for LDR_PRELOAD on AIX. The addition of 
set_perm(PERM_ROOT) before calling the nss open functions (needed
to avoid a GNU TLS bug) also broke LDR_PRELOAD.  Setting the effective
and then real uid to 0 for PERM_ROOT works around the issue.
 2012-02-06 15:46:17 -05:00
Todd C. Miller
656807823d For PERM_ROOT when using setreuid(), only set the euid to 0 prior 
to the call to setuid(0) if the current euid is non-zero.  This
effectively restores the state of things prior to rev 7bfeb629fccb.
Fixes a problem on AIX where LDR_PRELOAD was not being honored for
the command being executed.

Todd C. Miller
022591f4bf Add a wrapper for setgroups() that trims off extra groups and retries 
if setgroups() fails.  Also add some missing addrefs for PERM_USER
and PERM_FULL_USER.

b124635b04 Instead of keeping separate groups and gids arrays, create struct 
group_info and use it to store both, along with a count for each.
Cache group info on a per-user basis using getgrouplist() to get
the groups.  We no longer need special to special case the user or
list user for user_in_group() and thus no longer need to reset the
groups list when listing another user.

37873051a8 Make error strings translatable. 2011-07-13 16:50:25 -04:00
Todd C. Miller
56321ec778 Resolve the list of gids passed in from the sudo frontend (the 
result of getgroups()) to names and store both the group names and
ids in the sudo_user struct.  When matching groups in the sudoers
file, match based on the names in the groups list first and
only do a gid-based match when we absolutely have to.  By matching
on the group name (as it is listed in sudoers) instead of id
(which we would have to resolve) we save a lot of group lookups
for sudoers files with a lot of groups in them.

7c35601cf3 Be explicit when setting euid to 0 before call to setreuid(0, 0) 2011-04-23 06:13:48 -04:00
Todd C. Miller
b08ad6083b Work around weird AIX saved uid semantics on setuid() and setreuid(). 
On AIX, setuid() will only set the saved uid if the euid is already 0.
