====================
netdev-related stuff in vfs.git
There are several commits sitting in vfs.git that probably ought to go in
via net-next.git. First of all, there's merge with vfs.git#iocb - that's
Christoph's aio rework, which has triggered conflicts with the ->sendmsg()
and ->recvmsg() patches a while ago. It's not so much Christoph's stuff
that ought to be in net-next, as (pretty simple) conflict resolution on merge.
The next chunk is switch to {compat_,}import_iovec/import_single_range - new
safer primitives for initializing iov_iter. The primitives themselves come
from vfs/git#iov_iter (and they are used quite a lot in vfs part of queue),
conversion of net/socket.c syscalls belongs in net-next, IMO. Next there's
afs and rxrpc stuff from dhowells. And then there's sanitizing kernel_sendmsg
et.al. + missing inlined helper for "how much data is left in msg->msg_iter" -
this stuff is used in e.g. cifs stuff, but it belongs in net-next.
That pile is pullable from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem
I'll post the individual patches in there in followups; could you take a look
and tell if everything in there is OK with you?

Using a timer wheel for timewait sockets was nice ~15 years ago when
memory was expensive and machines had a single processor.
This does not scale, code is ugly and source of huge latencies
(Typically 30 ms have been seen, cpus spinning on death_lock spinlock.)
We can afford to use an extra 64 bytes per timewait sock and spread
timewait load to all cpus to have better behavior.
Tested:
On following test, /proc/sys/net/ipv4/tcp_tw_recycle is set to 1
on the target (lpaa24)
Before patch :
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
419594
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
437171
While test is running, we can observe 25 or even 33 ms latencies.
lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23
...
1000 packets transmitted, 1000 received, 0% packet loss, time 20601ms
rtt min/avg/max/mdev = 0.020/0.217/25.771/1.535 ms, pipe 2
lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23
...
1000 packets transmitted, 1000 received, 0% packet loss, time 20702ms
rtt min/avg/max/mdev = 0.019/0.183/33.761/1.441 ms, pipe 2
After patch :
About 90% increase of throughput :
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
810442
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
800992
And latencies are kept to minimal values during this load, even
if network utilization is 90% higher :
lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23
...
1000 packets transmitted, 1000 received, 0% packet loss, time 19991ms
rtt min/avg/max/mdev = 0.023/0.064/0.360/0.042 ms

Even if we make use of classifier and actions from the egress
path, we're going into handle_ing() executing additional code
on a per-packet cost for ingress qdisc, just to realize that
nothing is attached on ingress.
Instead, this can just be blinded out as a no-op entirely with
the use of a static key. On input fast-path, we already make
use of static keys in various places, e.g. skb time stamping,
in RPS, etc. It makes sense to not waste time when we're assured
that no ingress qdisc is attached anywhere.
Enabling/disabling of that code path is being done via two
helpers, namely net_{inc,dec}_ingress_queue(), that are being
invoked under RTNL mutex when a ingress qdisc is being either
initialized or destructed.

Intel Wired LAN Driver Updates 2015-04-11
This series contains updates to iflink, ixgbe and ixgbevf.
The entire set of changes come from Vlad Zolotarov to ultimately add
the ethtool ops to VF driver to allow querying the RSS indirection table
and RSS random key.
Currently we support only 82599 and x540 devices. On those devices, VFs
share the RSS redirection table and hash key with a PF. Letting the VF
query this information may introduce some security risks, therefore this
feature will be disabled by default.
The new netdev op allows a system administrator to change the default
behaviour with "ip link set" command. The relevant iproute2 patch has
already been sent and awaits for this series upstream.

The majority of the changes are from Marcel with lots of cleanup &
refactoring patches for the HCI UART driver. Marcel also split out some
Broadcom & Intel vendor specific functionality into two new btintel &
btbcm modules.
In addition to the HCI driver changes there's the completion of our

Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next tree.
They are:
* nf_tables set timeout infrastructure from Patrick Mchardy.
1) Add support for set timeout support.
2) Add support for set element timeouts using the new set extension
infrastructure.
4) Add garbage collection helper functions to get rid of stale elements.
Elements are accumulated in a batch that are asynchronously released
via RCU when the batch is full.
5) Add garbage collection synchronization helpers. This introduces a new
element busy bit to address concurrent access from the netlink API and the
garbage collector.
5) Add timeout support for the nft_hash set implementation. The garbage
collector peridically checks for stale elements from the workqueue.
* iptables/nftables cgroup fixes:
6) Ignore non full-socket objects from the input path, otherwise cgroup
match may crash, from Daniel Borkmann.
7) Fix cgroup in nf_tables.
8) Save some cycles from xt_socket by skipping packet header parsing when
skb->sk is already set because of early demux. Also from Daniel.
* br_netfilter updates from Florian Westphal.
9) Save frag_max_size and restore it from the forward path too.
10) Use a per-cpu area to restore the original source MAC address when traffic
is DNAT'ed.
11) Add helper functions to access physical devices.
12) Use these new physdev helper function from xt_physdev.
13) Add another nf_bridge_info_get() helper function to fetch the br_netfilter
state information.
14) Annotate original layer 2 protocol number in nf_bridge info, instead of
using kludgy flags.
15) Also annotate the pkttype mangling when the packet travels back and forth
from the IP to the bridge layer, instead of using a flag.
* More nf_tables set enhancement from Patrick:
16) Fix possible usage of set variant that doesn't support timeouts.
17) Avoid spurious "set is full" errors from Netlink API when there are pending
stale elements scheduled to be released.
18) Restrict loop checks to set maps.
19) Add support for dynamic set updates from the packet path.
20) Add support to store optional user data (eg. comments) per set element.
BTW, I have also pulled net-next into nf-next to anticipate the conflict
resolution between your okfn() signature changes and Florian's br_netfilter
updates.

When establishing a Bluetooth LE connection, read the remote used
features mask to determine which features are supported. This was
not really needed with Bluetooth 4.0, but since Bluetooth 4.1 and
also 4.2 have introduced new optional features, this becomes more
important.
This works the same as with BR/EDR where the connection enters the
BT_CONFIG stage and hci_connect_cfm call is delayed until the remote
features have been retrieved. Only after successfully receiving the
remote features, the connection enters the BT_CONNECTED state.

- A new driver for NXP NCI based chipsets, like e.g. the NPC100 or
the PN7150. It currently only supports an i2c physical layer, but
could easily be extended to work on top of e.g. SPI.
This driver also includes support for user space triggered firmware
updates.
- A few minor st21nfc[ab] fixes, cleanups, and comments improvements.
- A pn533 error return fix.
- A few NFC related logs formatting cleanups.

Use atomic operations for the element count to avoid races with async
updates.
To properly handle the transactional semantics during netlink updates,
deleted but not yet committed elements are accounted for seperately and
are treated as being already removed. This means for the duration of
a netlink transaction, the limit might be exceeded by the amount of
elements deleted. Set implementations must be prepared to handle this.

nf_bridge_info->mask is used for several things, for example to
remember if skb->pkt_type was set to OTHER_HOST.
For a bridge, OTHER_HOST is expected case. For ip forward its a non-starter
though -- routing expects PACKET_HOST.
Bridge netfilter thus changes OTHER_HOST to PACKET_HOST before hook
invocation and then un-does it after hook traversal.
This information is irrelevant outside of br_netfilter.
After this change, ->mask now only contains flags that need to be
known outside of br_netfilter in fast-path.
Future patch changes mask into a 2bit state field in sk_buff, so that
we can remove skb->nf_bridge pointer for good and consider all remaining
places that access nf_bridge info content a not-so fastpath.

right now we store this in the nf_bridge_info struct, accessible

Instead of using skb->nf_bridge->x, we use helpers to obtain the in/out

Followup patches to netfilter will then allow nf_bridge_info to be
obtained by a call into the br_netfilter core, rather than keeping a
pointer to it in sk_buff.

br_netfilter maintains an extra state, nf_bridge_info, which is attached
to skb via skb->nf_bridge pointer.
Amongst other things we use skb->nf_bridge->data to store the original
mac header for every processed skb.
This is required for ip refragmentation when using conntrack
on top of bridge, because ip_fragment doesn't copy it from original skb.
However there is no need anymore to do this unconditionally.
Move this to the one place where its needed -- when br_netfilter calls
ip_fragment().
Also switch to percpu storage for this so we can handle fragmenting
without accessing nf_bridge meta data.
Only user left is neigh resolution when DNAT is detected, to hold
the original source mac address (neigh resolution builds new mac header
using bridge mac), so rename ->data and reduce its size to whats needed.

Fast Open has been using an experimental option with a magic number
(RFC6994). This patch makes the client by default use the RFC7413
option (34) to get and send Fast Open cookies. This patch makes
the client solicit cookies from a given server first with the
RFC7413 option. If that fails to elicit a cookie, then it tries
the RFC6994 experimental option. If that also fails, it uses the
RFC7413 option on all subsequent connect attempts. If the server
returns a Fast Open cookie then the client caches the form of the
option that successfully elicited a cookie, and uses that form on
later connects when it presents that cookie.
The idea is to gradually obsolete the use of experimental options as
the servers and clients upgrade, while keeping the interoperability
meanwhile.

On the output paths in particular, we have to sometimes deal with two
socket contexts. First, and usually skb->sk, is the local socket that
generated the frame.
And second, is potentially the socket used to control a tunneling
socket, such as one the encapsulates using UDP.
We do not want to disassociate skb->sk when encapsulating in order
to fix this, because that would break socket memory accounting.
The most extreme case where this can cause huge problems is an
AF_PACKET socket transmitting over a vxlan device. We hit code
paths doing checks that assume they are dealing with an ipv4
socket, but are actually operating upon the AF_PACKET one.

Pull networking fixes from David Miller:
1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
previously SACK'd, from Neal Cardwell.
2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
from Cong WANG.
3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
from Cong WANG.
4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
5) When we encapsulate for a tunnel device, skb->sk still points to the
user socket. So this leads to cases where we retraverse the
ipv4/ipv6 output path with skb->sk being of some other address
family (f.e. AF_PACKET). This can cause things to crash since the
ipv4 output path is dereferencing an AF_PACKET socket as if it were
an ipv4 one.
The short term fix for 'net' and -stable is to elide these socket
checks once we've entered an encapsulation sequence by testing
xmit_recursion.
Longer term we have a better solution wherein we pass the tunnel's
socket down through the output paths, but that is way too invasive
for 'net' and -stable.
From Hannes Frederic Sowa.
6) l2tp_init() failure path forgets to unregister per-net ops, from
Cong WANG.
