Subject: pull request (net): ipsec 2021-08-04

1) Fix a sysbot reported memory leak in xfrm_user_rcv_msg.
   From Pavel Skripkin.

2) Revert "xfrm: policy: Read seqcount outside of rcu-read side
   in xfrm_policy_lookup_bytype". This commit tried to fix a
   lockin bug, but only cured some of the symptoms. A proper
   fix is applied on top of this revert.

3) Fix a locking bug on xfrm state hash resize. A recent change
   on sequence counters accidentally repaced a spinlock by a mutex.
   Fix from Frederic Weisbecker.

4) Fix possible user-memory-access in xfrm_user_rcv_msg_compat().
   From Dmitry Safonov.

5) Add initialiation sefltest fot xfrm_spdattr_type_t.
   From Dmitry Safonov.

Please pull or let me know if there are problems.

Thanks!
