[PATCH nf-next 00/19] Netfilter/IPVS updates for net-next

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

Hi,

The following patchset contains Netfilter/IPVS updates for net-next:

Patch #1 to #11 to shrink memory consumption for transaction objects:

  struct nft_trans_chain { /* size: 120 (-32), cachelines: 2, members: 10 */
  struct nft_trans_elem { /* size: 72 (-40), cachelines: 2, members: 4 */
  struct nft_trans_flowtable { /* size: 80 (-48), cachelines: 2, members: 5 */
  struct nft_trans_obj { /* size: 72 (-40), cachelines: 2, members: 4 */
  struct nft_trans_rule { /* size: 80 (-32), cachelines: 2, members: 6 */
  struct nft_trans_set { /* size: 96 (-24), cachelines: 2, members: 8 */
  struct nft_trans_table { /* size: 56 (-40), cachelines: 1, members: 2 */

  struct nft_trans_elem can now be allocated from kmalloc-96 instead of
  kmalloc-128 slab.

  Series from Florian Westphal. For the record, I have mangled patch #1
  to add nft_trans_container_*() and use if for every transaction object.
   I have also added BUILD_BUG_ON to ensure struct nft_trans always comes
  at the beginning of the container transaction object. And few minor
  cleanups, any new bugs are of my own.

Patch #12 simplify check for SCTP GSO in IPVS, from Ismael Luceno.

Patch #13 nf_conncount key length remains in the u32 bound, from Yunjian Wang.

Patch #14 removes unnecessary check for CTA_TIMEOUT_L3PROTO when setting
	  default conntrack timeouts via nfnetlink_cttimeout API, from
	  Lin Ma.

Patch #15 updates NFT_SECMARK_CTX_MAXLEN to 4096, SELinux could use
	  larger secctx names than the existing 256 bytes length.

Patch #16 fixes nfnetlink_queue with SCTP traffic, from Antonio Ojea.

Patch #17 adds a selftest for SCTP traffic under nfnetlink_queue,
	  also from Antonio.

Patch #18 adds a selftest to exercise nfnetlink_queue listeners leaving
	  nfnetlink_queue, from Florian Westphal.

Patch #19 increases hitcount from 255 to 65535 in xt_recent, from Phil Sutter.
