-#   [IPV4/IPV6]: IGMP source filter fixes
-#   
-#   When adding or deleting from the source list make sure to find matches
-#   by comparing against the new source address, not the group address.
-#   Also, check each addr in the list rather than just the first one.
-#   And, finally, only delete from list when there's a match rather than
-#   vice-versa.  Drop the effort to keep list sorted, since it's not done
-#   on full-state api and can create an sl_addr entry that the delta api
-#   won't be able to delete. Without these fixes sl_count can be corrupted
-#   which can allow for kernel memory corruption.

-#   [PATCH] shmctl SHM_LOCK perms
-#   
-#   Michael Kerrisk has observed that at present any process can SHM_LOCK any
-#   shm segment of size within process RLIMIT_MEMLOCK, despite having no
-#   permissions on the segment: surprising, though not obviously evil.  And any
-#   process can SHM_UNLOCK any shm segment, despite no permissions on it: that
-#   is surely wrong.
-#   
-#   Unless CAP_IPC_LOCK, restrict both SHM_LOCK and SHM_UNLOCK to when the
-#   process euid matches the shm owner or creator: that seems the least
-#   surprising behaviour, which could be relaxed if a need appears later.

-#   [PATCH] ia64/x86_64/s390 overlapping vma fix
-#   
-#   IA64 is also vulnerable to the huge-vma-in-executable bug in 64 bit elf
-#   support, it just insert a vma of zero page without checking overlap, so user
-#   can construct a elf with section begin from 0x0 to trigger this BUGON().
-#   
-#   However, I think it's safe to check overlap before we actually insert a vma
-#   into vma list.  And I also feel check vma overlap everywhere is unnecessary,
-#   because invert_vm_struct will check it again, so the check is duplicated.
-#   It's better to have invert_vm_struct return a value then let caller check if
-#   it successes.  Here is a patch against 2.6.10.rc2-mm3 I have tested it on
-#   i386, x86_64 and ia64 machines.
