Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree, most relevantly they are:
1) Extend nft_exthdr to allow to match TCP options bitfields, from
Manuel Messner.
2) Allow to check if IPv6 extension header is present in nf_tables,
from Phil Sutter.
3) Allow to set and match conntrack zone in nf_tables, patches from
Florian Westphal.
4) Several patches for the nf_tables set infrastructure, this includes
cleanup and preparatory patches to add the new bitmap set type.
5) Add optional ruleset generation ID check to nf_tables and allow to
delete rules that got no public handle yet via NFTA_RULE_ID. These
patches add the missing kernel infrastructure to support rule
deletion by description from userspace.
6) Missing NFT_SET_OBJECT flag to select the right backend when sets

7) A couple of cleanups for the expectation and SIP helper, from Gao

This new attribute allows us to uniquely identify a rule in transaction.
Robots may trigger an insertion followed by deletion in a batch, in that
scenario we still don't have a public rule handle that we can use to
delete the rule. This is similar to the NFTA_SET_ID attribute that
allows us to refer to an anonymous set from a batch.

This patch implements the check generation id as provided by nfnetlink.
This allows us to reject ruleset updates against stale baseline, so
userspace can retry update with a fresh ruleset cache.
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
This patch allows userspace to specify the generation ID that has been
used to build an incremental batch update.
If userspace specifies the generation ID in the batch message as
attribute, then nfnetlink compares it to the current generation ID so
you make sure that you work against the right baseline. Otherwise, bail
out with ERESTART so userspace knows that its changeset is stale and
needs to respin. Userspace can do this transparently at the cost of
taking slightly more time to refresh caches and rework the changeset.
This check is optional, if there is no NFNL_BATCH_GENID attribute in the
batch begin message, then no check is performed.

Refactor macvtap to re-use tap functionality by other virtual intefaces

well. This switch from 243 to 368 tests.

The geteuid() check is replaced with a capability check.

Netronome NFP4000 and NFP6000 PF driver
This is a base PF driver for Netronome NFP4000 and NFP6000 chips. This
series doesn't add any exciting new features, it provides a foundation
for supporting more advanced firmware applications.
Patch 1 moves a bitfield-related helper from our BPF code to the global
header.
Patch 2 renames the kernel module and adds a new main file. We were
considering 3-module approach (pf, vf, common netdev library) but
ultimately settled on a single module to keep things simple.
Patch 3 adds support for accessing chip internals. It provides a way of
configuring access windows to different parts of chip memory and issuing
pretty much any commands on chip's NoC.
Patches 4, 5, 6, 7, 8 provide support for accessing and interpreting
various hardware and firmware information structures.
Patch 9 introduces service processor (NSP) ABI. This ABI gives us
access to PHY/SFP module configuration and information as well as
methods for unloading and loading application firmware.
Patches 10 and 11 modify the existing netdev code to make it possible
to support multi-port devices (sharing a PCI device).
Patch 12 adds a new driver probe path which will be used for the PF
PCI device IDs. It utilizes the newly added infrastructure and is able
to load application FW and spawn netdevs for all card's ports.
