====================
pull request (net): ipsec 2026-05-29

1) xfrm: route MIGRATE notifications to caller's netns
   Thread the caller's netns through km_migrate() so that
   MIGRATE notifications go to the issuing netns, fixing both the
   init_net listener leak and MOBIKE notifications inside
   non-init netns. From Maoyi Xie.

2) xfrm: ipcomp: Free destination pages on acomp errors
   Move the out_free_req label up so that allocated destination
   pages are released on decompression errors, not only on success.
   From Herbert Xu.

3) xfrm: Check for underflow in xfrm_state_mtu
   Reject configurations that cause xfrm_state_mtu() to underflow,
   preventing a negative TFCPAD value from becoming a memset size
   that triggers an out-of-bounds write of several terabytes.
   From David Ahern.

4) xfrm: ah: use skb_to_full_sk in async output callbacks
   Convert the possibly-incomplete skb->sk to a full socket pointer
   in async AH callbacks so that a request_sock or timewait_sock
   never reaches xfrm_output_resume() downstream consumers.
   From Michael Bommarito.

5) Add and revert: esp: fix page frag reference leak on skb_to_sgvec failure
   The patch does not fix te issue completely.

6) xfrm: esp: restore combined single-frag length gate
   Check the aligned post-trailer combined length against a page limit
   in the fast path, preventing skb_page_frag_refill() from falling
   back to a page too small for the destination scatterlist.
   From Jingguo Tan.

7) xfrm: iptfs: reset runtime state when cloning SAs
   Reinitialise the clone's mode_data runtime objects before
   publishing it, preventing queued skbs from being freed with
   list state copied from the original SA when migration fails.
   From Shaomin Chen.

8) xfrm: move policy_bydst RCU sync from per-netns .exit to .pre_exit
   Flush policy tables and drain the workqueue in a .pre_exit handler
   so that cleanup_net() pays one RCU grace period per batch instead
   of one per namespace, fixing stalls at high CLONE_NEWNET rates.
   From Usama Arif.

9) xfrm: input: hold netns during deferred transport reinjection
   Take a netns reference when queueing deferred transport reinjection
   work and drop it after the callback completes, keeping the skb->cb
   net pointer valid until the deferred work runs.
   From Zhengchuan Liang.
