+#   [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.
