Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree, mostly from Florian Westphal to sort out the lack of sufficient
validation in x_tables and connlabel preparation patches to add
nf_tables support. They are:

1) Ensure we don't go over the ruleset blob boundaries in
   mark_source_chains().

2) Validate that target jumps land on an existing xt_entry. This extra
   sanitization comes with a performance penalty when loading the ruleset.

3) Introduce xt_check_entry_offsets() and use it from {arp,ip,ip6}tables.

4) Get rid of the smallish check_entry() functions in {arp,ip,ip6}tables.

5) Make sure the minimal possible target size in x_tables.

6) Similar to #3, add xt_compat_check_entry_offsets() for compat code.

7) Check that standard target size is valid.

8) More sanitization to ensure that the target_offset field is correct.

9) Add xt_check_entry_match() to validate that matches are well-formed.

10-12) Three patch to reduce the number of parameters in
    translate_compat_table() for {arp,ip,ip6}tables by using a container
    structure.

13) No need to return value from xt_compat_match_from_user(), so make
    it void.

14) Consolidate translate_table() so it can be used by compat code too.

15) Remove obsolete check for compat code, so we keep consistent with
    what was already removed in the native layout code (back in 2007).

16) Get rid of target jump validation from mark_source_chains(),
    obsoleted by #2.

17) Introduce xt_copy_counters_from_user() to consolidate counter
    copying, and use it from {arp,ip,ip6}tables.

18,22) Get rid of unnecessary explicit inlining in ctnetlink for dump
    functions.

19) Move nf_connlabel_match() to xt_connlabel.

20) Skip event notification if connlabel did not change.

21) Update of nf_connlabels_get() to make the upcoming nft connlabel
    support easier.

23) Remove spinlock to read protocol state field in conntrack.

Currently all drivers depend and autoload the vxlan module because how
vxlan_get_rx_port is linked into them. Remove this dependency:

By using a new event type in the netdevice notifier call chain we proxy
the request from the drivers to flush and resetup the vxlan ports not
directly via function call but by the already existing netdevice
notifier call chain.

I added a separate new event type, NETDEV_OFFLOAD_PUSH_VXLAN, to do so.
We don't need to save those ids, as the event type field is an unsigned
long and using specialized event types for this purpose seemed to be a
more elegant way. This also comes in beneficial if in future we want to
add offloading knobs for vxlan.

atl2 includes NETIF_F_SG in hw_features even though it has no support

driver does not claim to implement checksum offload and that used to
be a requirement for SG.

Now that SG and checksum offload are independent features, if you
explicitly enable SG *and* use one of the rare protocols that can use
SG without checkusm offload, this potentially leaks sensitive
information (before you notice that it just isn't working).  Therefore
this obscure bug has been designated CVE-2016-2117.

Mellanox 100G mlx5 driver receive path optimizations

Changes from V2:
	- Rebased to 46e7b8d8 ("net: dsa: kill circular reference with slave priv")
	- Updated: ("net/mlx5e: Support RX multi-packet WQE (Striding RQ)")
		* Per Eric Dumazet comment we changed the driver memory handling scheme to
		work with order-0 pages rather than order-5 via split_page().
		* This means that now a mlx5e rx skb can hold one or (more in case of HW LRO)
                skb frag each pointing to a 4K order-0 page rather than one frag with order-5 page.
	- Updated: ("net/mlx5e: Add fragmented memory support for RX multi packet WQE")
		* Code refactoring and code reuse due the split_page() mechanism,
		  now the MPWQE and fragmented MPWQE handling almost look the same,
		  and share most of the code.
	- In some cases we see 2%-3% packet rate degradation in comparison to the order-5 pages approach,
	  due to split_page() cpu consumption, but still we do see 3%-10% improvement in comparison to the
          current linear SKB approach.
	- We do believe that now the driver memory scheme is significantly less vulnerable
	  to the memory DOS attack Eric pointed at.

	- Added: ("net/mlx5e: Delay skb->data access")
		Small trivial optimization.
	- Updated: ("net/mlx5e: Support RX multi-packet WQE (Striding RQ)")
	 	Changed Striding RQ defaults to:
			> 	NUM WQEs = 16
			> 	Strides Per WQE = 1024
			> 	Stride Size = 128
	- Updated: ("net/mlx5e: Use napi_alloc_skb for RX SKB allocations")
		Consider the IP packet alignment already done in napi_alloc_skb.

Changes from V0:
	- Fixed a typo in commit message reported by Sergei
	- Align SKB fragments truesize to stride size
	- Use skb_add_rx_frag and remove the use of SKB_TRUESIZE
	- Fix: # MTTs alignment on Power PC
	- Fix: Free original (unaligned) pointer of MTT array

This series includes Some RX modifications and optimizations for
the mlx5 Ethernet driver.

queue counters.

From Tariq, several patches that are centralized around improving
RX path message rate, CPU and Memory utilization, in each patch
commit message you will find the performance improvements numbers
related to that specific patch.

In the 2nd patch we used a queue counter to report "out of buffer"
dropped packet count, "Dropped packets due to lack of software resources"

3rd patch modifies the driver's to RSS default value to be spread along the
close NUMA node cores only for better out of the box experience.

In the 4th and 5th patches we utilized the use of RX multi-packet WQE
(Striding RQ) for better memory utilization especially in case of hardware
LRO is enabled and for better message rate for small packets.

In the 6th and 7th patches we added a fallback mechanism to use fragmented
memory when allocating large WQE strides fails, using UMR
(User Memory Registration) and ICO (Internal Control Operations) SQs.

In the 8th to 11th patches we did some small modification which show some small
extra improvements.

Introduce the feature of multi-packet WQE (RX Work Queue Element)
referred to as (MPWQE or Striding RQ), in which WQEs are larger
and serve multiple packets each.

Every WQE consists of many strides of the same size, every received
packet is aligned to a beginning of a stride and is written to
consecutive strides within a WQE.

In the regular approach, each regular WQE is big enough to be capable
of serving one received packet of any size up to MTU or 64K in case of
device LRO is enabled, making it very wasteful when dealing with
small packets or device LRO is enabled.

For its flexibility, MPWQE allows a better memory utilization
(implying improvements in CPU utilization and packet rate) as packets
consume strides according to their size, preserving the rest of
the WQE to be available for other packets.

MPWQE default configuration:
	Num of WQEs	= 16
	Strides Per WQE = 2048
	Stride Size	= 64 byte

The default WQEs memory footprint went from 1024*mtu (~1.5MB) to
16 * 2048 * 64 = 2MB per ring.
However, HW LRO can now be supported at no additional cost in memory
footprint, and hence we turn it on by default and get an even better
performance.

Performance tested on ConnectX4-Lx 50G.
To isolate the feature under test, the numbers below were measured with
HW LRO turned off. We verified that the performance just improves when
LRO is turned back on.

* Netperf single TCP stream:
- BW raised by 10-15% for representative packet sizes:
  default, 64B, 1024B, 1478B, 65536B.

* Netperf multi TCP stream:
- No degradation, line rate reached.

* Pktgen: packet rate raised by 2-10% for traffic of different message
sizes: 64B, 128B, 256B, 1024B, and 1500B.

* Pktgen: packet loss in bursts of small messages (64byte),
single stream:
- | num packets | packets loss before | packets loss after
  |     2K      |       ~ 1K          |       0
  |     8K      |       ~ 6K          |       0
  |     16K     |       ~13K          |       0
  |     32K     |       ~28K          |       0
  |     64K     |       ~57K          |     ~24K

As expected as the driver can receive as many small packets (<=64B) as
the number of total strides in the ring (default = 2048 * 16) vs. 1024
(default ring size regardless of packets size) before this feature.
