[PATCH net-next 0/6] Netfilter updates for net-next

[PATCH net-next 0/6] Netfilter updates for net-next

[Pablo Neira Ayuso]

Hi,

The following patchset contains Netfilter updates for net-next:

1) Fix sparse warning in the new nft_inner expression, reported
   by Jakub Kicinski.

2) Incorrect vlan header check in nft_inner, from Peng Wu.

3) Two patches to pass reset boolean to expression dump operation,
   in preparation for allowing to reset stateful expressions in rules.
   This adds a new NFT_MSG_GETRULE_RESET command. From Phil Sutter.

4) Inconsistent indentation in nft_fib, from Jiapeng Chong.

5) Speed up siphash calculation in conntrack, from Florian Westphal.

This batch includes two fixes for the new inner payload/meta match
coming in the previous nf-next pull request.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next.git

Thanks.

[PATCH net-next 1/6] netfilter: nft_payload: use __be16 to store gre version

[Pablo Neira Ayuso]

GRE_VERSION and GRE_VERSION0 are expressed in network byte order,
use __be16. Uncovered by sparse:

net/netfilter/nft_payload.c:112:25: warning: incorrect type in assignment (different base types)
net/netfilter/nft_payload.c:112:25:    expected unsigned int [usertype] version
net/netfilter/nft_payload.c:112:25:    got restricted __be16
net/netfilter/nft_payload.c:114:22: warning: restricted __be16 degrades to integer

[PATCH net-next 2/6] netfilter: nft_inner: fix return value check in nft_inner_parse_l2l3()

[Pablo Neira Ayuso]

From: Peng Wu <wupeng58@huawei.com>

In nft_inner_parse_l2l3(), the return value of skb_header_pointer() is
'veth' instead of 'eth' when case 'htons(ETH_P_8021Q)' and fix it.

[PATCH net-next 3/6] netfilter: nf_tables: Extend nft_expr_ops::dump callback parameters

[Pablo Neira Ayuso]

From: Phil Sutter <phil@nwl.cc>

Add a 'reset' flag just like with nft_object_ops::dump. This will be
useful to reset "anonymous stateful objects", e.g. simple rule counters.

No functional change intended.

[PATCH net-next 4/6] netfilter: nf_tables: Introduce NFT_MSG_GETRULE_RESET

[Pablo Neira Ayuso]

From: Phil Sutter <phil@nwl.cc>

Analogous to NFT_MSG_GETOBJ_RESET, but for rules: Reset stateful
expressions like counters or quotas. The latter two are the only
consumers, adjust their 'dump' callbacks to respect the parameter
introduced earlier.

[PATCH net-next 6/6] netfilter: conntrack: use siphash_4u64

[Pablo Neira Ayuso]

From: Florian Westphal <fw@strlen.de>

This function is used for every packet, siphash_4u64 is noticeably faster
than using local buffer + siphash:

Before:
  1.23%  kpktgend_0       [kernel.vmlinux]     [k] __siphash_unaligned
  0.14%  kpktgend_0       [nf_conntrack]       [k] hash_conntrack_raw
After:
  0.79%  kpktgend_0       [kernel.vmlinux]     [k] siphash_4u64
  0.15%  kpktgend_0       [nf_conntrack]       [k] hash_conntrack_raw

In the pktgen test this gives about ~2.4% performance improvement.

Hi, Mr Nit Pick here, can we silence the spatse warnings?

net/netfilter/nf_conntrack_core.c:222:14: warning: cast from restricted __be16
net/netfilter/nf_conntrack_core.c:222:55: warning: restricted __be16 degrades to integer

This one appears to break the build transiently (next patch fixes it).
Any chance for a rebase? Bisection potentially getting broken by this
and all that..

[PATCH net-next 3/6] netfilter: nf_tables: Extend nft_expr_ops::dump callback parameters

[Pablo Neira Ayuso]

From: Phil Sutter <phil@nwl.cc>

Add a 'reset' flag just like with nft_object_ops::dump. This will be
useful to reset "anonymous stateful objects", e.g. simple rule counters.

No functional change intended.
