Cyrill Gorcunov 79f0713d40 prctl: use CAP_SYS_RESOURCE for PR_SET_MM option ... CAP_SYS_ADMIN is already overloaded left and right, so to have more fine-grained access control use CAP_SYS_RESOURCE here. The CAP_SYS_RESOUCE is chosen because this prctl option allows a current process to adjust some fields of memory map descriptor which rather represents what the process owns: pointers to code, data, stack segments, command line, auxiliary vector data and etc. Suggested-by: Michael Kerrisk <mtk.manpages@gmail.com> Acked-by: Kees Cook <keescook@chromium.org> Acked-by: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Pavel Emelyanov <xemul@parallels.com> Cc: Tejun Heo <tj@kernel.org> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Paul Bolle <pebolle@tiscali.nl> Cc: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2012-03-15 17:03:03 -07:00
