[PATCH net 0/4] Netfilter fixes for net

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi,

The following patchset contains Netfilter fixes for net:

1) Perform SCTP vtag verification for ABORT/SHUTDOWN_COMPLETE according
   to RFC 9260, Sect 8.5.1.

2) Fix infinite loop if SCTP chunk size is zero in for_each_sctp_chunk().
   And remove useless check in this macro too.

3) Revert DATA_SENT state in the SCTP tracker, this was applied in the
   previous merge window. Next patch in this series provides a more
   simple approach to multihoming support.

4) Unify HEARTBEAT_ACKED and ESTABLISHED states for SCTP multihoming
   support, use default ESTABLISHED of 210 seconds based on
   heartbeat timeout * maximum number of retransmission + round-trip timeout.
   Otherwise, SCTP conntrack entry that represents secondary paths
   remain stale in the table for up to 5 days.

This is a slightly large batch with fixes for the SCTP connection
tracking helper, all patches from Sriram Yagnaraman.
