** Description changed:
- SRU Justification
+ kernel: request_module() OOM local DoS
- Upstream commits:
-
- (1) 70834d30 "usermodehelper: use UMH_WAIT_PROC consistently"
- (2) b3449922 "usermodehelper: introduce umh_complete(sub_info)"
- (3) d0bd587a "usermodehelper: implement UMH_KILLABLE"
- (4) 9d944ef3 "usermodehelper: kill umh_wait, renumber UMH_* constants"
- (5) 5b9bd473 "usermodehelper: ____call_usermodehelper() doesn't need
do_exit()"
- (6) 3e63a93b "kmod: introduce call_modprobe() helper"
- (7) 1cc684ab "kmod: make __request_module() killable"
-
- Description:
-
- Since 2.6.11, an unprivileged local user can easily keep the system under
- memory starvation state by temporarily disabling the OOM killer due to the OOM
- killer deadlock. Although we haven't eliminated all of possible attack
vectors,
- this patchset can eliminate the most straightforward attack vector.
-
- Notes:
-
- (1) and (4) are optional. (4) depends on (1). (1) needs some corrections if we
- backport. For example, (1) does not include fix for ubuntu/fsam7400/fsam7400.c
- in precise.git. Therefore, I think excluding (1) and (4) is a safer choice.
-
- 3.4-rc1 will include (4) anyway. Please make sure that all users (including
- ubuntu/fsam7400/fsam7400.c) started using UMH_* constants.
