Dmitry Kravkov reported packet drops for GRE packets since GRO support
was added.
There is a race in gro_cell_poll() because we call napi_complete()
without any synchronization with a concurrent gro_cells_receive()
Once bug was triggered, we queued packets but did not schedule NAPI
poll.
We can fix this issue using the spinlock protected the napi_skbs queue,
as we have to hold it to perform skb dequeue anyway.
As we open-code skb_dequeue(), we no longer need to mask IRQS, as both
producer and consumer run under BH context.

This patch adds the multiqueue (VIRTIO_NET_F_MQ) support to virtio_net

transmission and reception through multiple queue pairs and does the packet
steering to get better performance. By default, one one queue pair is used, user
could change the number of queue pairs by ethtool in the next patch.
When multiple queue pairs is used and the number of queue pairs is equal to the
number of vcpus. Driver does the following optimizations to implement per-cpu
virt queue pairs:
- select the txq based on the smp processor id.
- smp affinity hint to the cpu that owns the queue pairs.
This could be used with the flow steering support of the device to guarantee the
packets of a single flow is handled by the same cpu.

This patch adds support in the kernel for offloading in the NIC Tx and Rx
checksumming for encapsulated packets (such as VXLAN and IP GRE).
For Tx encapsulation offload, the driver will need to set the right bits
in netdev->hw_enc_features. The protocol driver will have to set the
skb->encapsulation bit and populate the inner headers, so the NIC driver will
use those inner headers to calculate the csum in hardware.
For Rx encapsulation offload, the driver will need to set again the
skb->encapsulation flag and the skb->ip_csum to CHECKSUM_UNNECESSARY.
In that case the protocol driver should push the decapsulated packet up
to the stack, again with CHECKSUM_UNNECESSARY. In ether case, the protocol
driver should set the skb->encapsulation flag back to zero. Finally the
protocol driver should have NETIF_F_RXCSUM flag set in its features.

====================
Changes since v1:
-get rid of essentially unused variable spotted by
Neil Horman (patch #2)
-drop patch #3; defer it for 3.9 content, so Neil,
Jon and Ying can discuss its specifics at their
leisure while net-next is closed. (It had no
direct dependencies to the rest of the series, and
was just an optimization)
-fix indentation of accept() code directly in place
vs. forking it out to a separate function (was patch
#10, now patch #9).
Rebuilt and re-ran tests just to ensure nothing odd happened.
Original v1 text follows, updated pull information follows that.

Here is another batch of TIPC changes. The most interesting
thing is probably the non-blocking socket connect - I'm told
there were several users looking forward to seeing this.
Also there were some resource limitation changes that had
the right intent back in 2005, but were now apparently causing
needless limitations to people's real use cases; those have
been relaxed/removed.
There is a lockdep splat fix, but no need for a stable backport,
since it is virtually impossible to trigger in mainline; you
have to essentially modify code to force the probabilities
in your favour to see it.
The rest can largely be categorized as general cleanup of things
seen in the process of getting the above changes done.
Tested between 64 and 32 bit nodes with the test suite. I've
also compile tested all the individual commits on the chain.
I'd originally figured on this queue not being ready for 3.8, but
the extended stabilization window of 3.7 has changed that. On
the other hand, this can still be 3.9 material, if that simply
works better for folks - no problem for me to defer it to 2013.
If anyone spots any problems then I'll definitely defer it,
rather than rush a last minute respin.

In TIPC's accept() routine, there is a large block of code relating
to initialization of a new socket, all within an if condition checking
if the allocation succeeded.
Here, we simply flip the check of the if, so that the main execution
path stays at the same indentation level, which improves readability.
If the allocation fails, we jump to an already existing exit label.

TIPC accept() call grabs the socket lock on a newly allocated
socket while holding the socket lock on an old socket. But lockdep
worries that this might be a recursive lock attempt:
[ INFO: possible recursive locking detected ]
---------------------------------------------
kworker/u:0/6 is trying to acquire lock:
(sk_lock-AF_TIPC){+.+.+.}, at: [<c8c1226c>] accept+0x15c/0x310 [tipc]
but task is already holding lock:
(sk_lock-AF_TIPC){+.+.+.}, at: [<c8c12138>] accept+0x28/0x310 [tipc]
other info that might help us debug this:
Possible unsafe locking scenario:
CPU0
----
lock(sk_lock-AF_TIPC);
lock(sk_lock-AF_TIPC);
*** DEADLOCK ***
May be due to missing lock nesting notation
[...]
Tell lockdep that this locking is safe by using lock_sock_nested().
This is similar to what was done in commit 5131a184a3 for
SCTP code ("SCTP: lock_sock_nested in sctp_sock_migrate").
Also note that this is isn't something that is seen normally,
as it was uncovered with some experimental work-in-progress
code not yet ready for mainline. So no need for stable
backports or similar of this commit.

TIPC has so far only supported blocking connect(), meaning that a call
to connect() doesn't return until either the connection is fully
established, or an error occurs. This has proved insufficient for many
users, so we now introduce non-blocking connect(), analogous to how
this is done in TCP and other protocols.
With this feature, if a connection cannot be established instantly,
connect() will return the error code "-EINPROGRESS".
If the user later calls connect() again, he will either have the
return code "-EALREADY" or "-EISCONN", depending on whether the
connection has been established or not.
The user must have explicitly set the socket to be non-blocking
(SOCK_NONBLOCK or O_NONBLOCK, depending on method used), so unless
for some reason they had set this already (the socket would anyway
remain blocking in current TIPC) this change should be completely
backwards compatible.
It is also now possible to call select() or poll() to wait for the
completion of a connection.
An effect of the above is that the actual completion of a connection
may now be performed asynchronously, independent of the calls from
user space. Therefore, we now execute this code in BH context, in
the function filter_rcv(), which is executed upon reception of
messages in the socket.

[PG: minor refactoring for improved connect/disconnect function names]
Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
Handling of connection-related message reception is currently scattered
around at different places in the code. This makes it harder to verify
that things are handled correctly in all possible scenarios.
So we consolidate the existing processing of connection-oriented
message reception in a single routine. In the process, we convert the
chain of if/else into a switch/case for improved readability.
A cast on the socket_state in the switch is needed to avoid compile
warnings on 32 bit, like "net/tipc/socket.c:1252:2: warning: case value
‘4294967295’ not in enumerated type". This happens because existing
tipc code pseudo extends the default linux socket state values with:
#define SS_LISTENING -1 /* socket is listening */
#define SS_READY -2 /* socket is connectionless */
It may make sense to add these as _positive_ values to the existing
socket state enum list someday, vs. these already existing defines.

Currently we have tipc_disconnect and tipc_disconnect_port. It is
not clear from the names alone, what they do or how they differ.
It turns out that tipc_disconnect just deals with the port locking
and then calls tipc_disconnect_port which does all the work.
If we rename as follows: tipc_disconnect_port --> __tipc_disconnect
then we will be following typical linux convention, where:
__tipc_disconnect: "raw" function that does all the work.
tipc_disconnect: wrapper that deals with locking and then calls
the real core __tipc_disconnect function
With this, the difference is immediately evident, and locking
violations are more apt to be spotted by chance while working on,
or even just while reading the code.
On the connect side of things, we currently only have the single
"tipc_connect2port" function. It does both the locking at enter/exit,
and the core of the work. Pending changes will make it desireable to
have the connect be a two part locking wrapper + worker function,
just like the disconnect is already.
Here, we make the connect look just like the updated disconnect case,
for the above reason, and for consistency. In the process, we also
get rid of the "2port" suffix that was on the original name, since
it adds no descriptive value.
On close examination, one might notice that the above connect
changes implicitly move the call to tipc_link_get_max_pkt() to be
within the scope of tipc_port_lock() protected region; when it was
not previously. We don't see any issues with this, and it is in
keeping with __tipc_connect doing the work and tipc_connect just
handling the locking.

As a complement to the per-socket sk_recv_queue limit, TIPC keeps a
global atomic counter for the sum of sk_recv_queue sizes across all
tipc sockets. When incremented, the counter is compared to an upper
threshold value, and if this is reached, the message is rejected
with error code TIPC_OVERLOAD.
This check was originally meant to protect the node against
buffer exhaustion and general CPU overload. However, all experience
indicates that the feature not only is redundant on Linux, but even
harmful. Users run into the limit very often, causing disturbances
for their applications, while removing it seems to have no negative
effects at all. We have also seen that overall performance is
boosted significantly when this bottleneck is removed.
Furthermore, we don't see any other network protocols maintaining
such a mechanism, something strengthening our conviction that this
control can be eliminated.
As a result, the atomic variable tipc_queue_size is now unused
and so it can be deleted. There is a getsockopt call that used
to allow reading it; we retain that but just return zero for
maximum compatibility.

This includes a Bluetooth pull. Gustavo says:
"A few more patches to 3.8, I hope they can still make it to mainline!
The most important ones are the socket option for the SCO protocol to allow

Also, a mac80211 pull. Johannes says:
"If you think there's any chance this might make it still, please pull my

of fixes to the previous code, as well as a few small features:
* VHT association in mac80211
* some new debugfs files
* P2P GO powersave configuration
* masked MAC address verification
The biggest patch is probably the BSS struct changes to use RCU for
their IE buffers to fix potential races. I've not tagged this for stable
because it's pretty invasive and nobody has ever seen any bugs in this
area as far as I know."

On error, the error code from tun_flow_init() is lost inside
tun_set_iff(), this patch fixes this by assigning the tun_flow_init()
error code to the "err" variable which is returned by
the tun_flow_init() function on error.

WARNING: net/sctp/sctp.o(.text+0x72f1): Section mismatch in reference
from the function sctp_net_init() to the function
.init.text:sctp_proc_init()
The function sctp_net_init() references
the function __init sctp_proc_init().
This is often because sctp_net_init lacks a __init
annotation or the annotation of sctp_proc_init is wrong.
And put __net_init after 'int' for sctp_proc_init - as it is done
everywhere else in the sctp-stack.

The get_clock() of the chelsio driver clashes with the s390 one.
The chelsio helper reads a timespec via ktime just to convert it
back to ktime. I can see no different outcome from calling
ktime_get directly.
Remove the get_clock and use ktime_get directly.

It is possible that the driver is configured to operate with a certain
link configuration which differs from the link's configuration during
boot from SAN - this would cause the driver to flap the link.
Said flap may be missed by specific switches, causing dcbx convergence
to be too long and boot sequence to fail. Convergence is longer because
switch ignores new dcbx packets due to counters mismatch, as only host
side reset the counters due to the link flap.
This patch causes the driver to ignore user's initial configuration during
boot from SAN, and continues with the existing link configuration.
