Eric Dumazet ae08ce0021 netfilter: nfnetlink_queue: zero copy support
nfqnl_build_packet_message() actually copy the packet
inside the netlink message, while it can instead use
zero copy.

Make sure the skb 'copy' is the last component of the
cooked netlink message, as we cant add anything after it.

Patch cooked in Copenhagen at Netfilter Workshop ;)

Still to be addressed in separate patches :

-GRO/GSO packets are segmented in nf_queue()
and checksummed in nfqnl_build_packet_message().

Proper support for GSO/GRO packets (no segmentation,
and no checksumming) needs application cooperation, if we
want no regressions.

Baker Zhang b5fb82c48b xfrm: use xfrm direction when lookup policy
because xfrm policy direction has same value with corresponding
flow direction, so this problem is covered.

In xfrm_lookup and __xfrm_policy_check, flow_cache_lookup is used to
accelerate the lookup.

Flow direction is given to flow_cache_lookup by policy_to_flow_dir.

When the flow cache is mismatched, callback 'resolver' is called.

'resolver' requires xfrm direction,
so convert direction back to xfrm direction.

Hannes Frederic Sowa 5a3da1fe95 inet: limit length of fragment queue hash table bucket lists
This patch introduces a constant limit of the fragment queue hash
table bucket list lengths. Currently the limit 128 is choosen somewhat
arbitrary and just ensures that we can fill up the fragment cache with
empty packets up to the default ip_frag_high_thresh limits. It should
just protect from list iteration eating considerable amounts of cpu.

If we reach the maximum length in one hash bucket a warning is printed.
This is implemented on the caller side of inet_frag_find to distinguish
between the different users of inet_fragment.c.

I dropped the out of memory warning in the ipv4 fragment lookup path,
because we already get a warning by the slab allocator.

Julian Anastasov 0c12582fbc ipvs: add backup_only flag to avoid loops
Dmitry Akindinov is reporting for a problem where SYNs are looping
between the master and backup server when the backup server is used as
real server in DR mode and has IPVS rules to function as director.

Even when the backup function is enabled we continue to forward
traffic and schedule new connections when the current master is using
the backup server as real server. While this is not a problem for NAT,
for DR and TUN method the backup server can not determine if a request
comes from client or from director.

To avoid such loops add new sysctl flag backup_only. It can be needed
for DR/TUN setups that do not need backup and director function at the
same time. When the backup function is enabled we stop any forwarding
and pass the traffic to the local stack (real server mode). The flag
disables the director function when the backup function is enabled.

For setups that enable backup function for some virtual services and
director function for other virtual services there should be another
more complex solution to support DR/TUN mode, may be to assign
per-virtual service syncid value, so that we can differentiate the
requests.

Helmut Schaa 8857d6dc77 rt2x00: Fix tx status reporting for reordered frames in rt2800pci
rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.

For example a tx queue
	[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
	[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.

To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.

This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.

Yogesh Ashok Powar 43283febfd mwifiex: cleanup VHT cap
Firmware returned VHT cap has the same format that cfg80211
expects. There is no need to parse the vht cap from the firmware
and then set it to ieee80211_sta_vht_cap. Just copying is
sufficient.
