Subject: [PATCH v2 net-next 0/2] fix use-after-free bugs in skb list
 processing

A couple of bugs in skb list handling were spotted by Dan Carpenter, with
 the help of Smatch; following up on them I found a couple more similar
 cases.  This series fixes them by changing the relevant loops to use the
 dequeue-enqueue model (rather than in-place list modification).

v2: dropped patch #3 (new list.h helper), per DaveM's request.

Edward Cree (2):
  net: core: fix uses-after-free in list processing
  netfilter: fix use-after-free in NF_HOOK_LIST
