This patch has some issues that are fixed with a followup patch. 6) xfrm: Fix skb double-free in xfrm_dev_direct_output() Stop freeing the skb unconditionally in xfrm_dev_direct_output(), letting local_out()'s result indicate when ownership has moved on. 7) xfrm: ah6: validate routing header segments_left Validate the segments_left/hdrlen invariant before rearranging the routing-header addresses, avoiding an OOB memmove on malformed HDRINCL packets. 8) xfrm: fix xfrm_state_construct() auth-trunc leak Detect an already-attached auth-trunc allocation by the pointer rather than inferring it from the algorithm id, so a prior attach isn't overwritten and lost. 9) xfrm: bound nat keepalive state collection Replace the per-state allocation in the NAT keepalive walk with a fixed-size batch that drains under BH-disabled locking and resumes from the cursor, bounding the worker's memory. Please pull or let me know if there are problems. Thanks!
