Christoph Paasch found netxen could trigger a BUG in its dismantle
phase, in netxen_release_tx_buffer(), using full size TSO packets.
cmd_buf->frag_count includes the skb->data part, so the loop must
start at index 1 instead of 0, or else we can make an out
of bound access to cmd_buff->frag_array[MAX_SKB_FRAGS + 2]
Christoph provided the fixes in netxen_map_tx_skb() function.
In case of a dma mapping error, its better to clear the dma fields
so that we don't try to unmap them again in netxen_release_tx_buffer()

If subtracting 12 from l leaves zero we'd do a zero size allocation,
leading to an oops later when we try to set the NUL terminator.

====================
The 2 first patches in this series are required to make the Sierra
Wireless MC7710 card work in MBIM mode. They may also be
required for other Qualcomm firmware based MBIM devices.
Patch #1 was previously posted as a standalone patch. This version
is a replacement, removing a theoretical NULL pointer exception.
Patch #3 fixes a bug I introduced in v3.7

We normally avoid sending ZLPs by padding NTBs with a zero byte
if the NTB is shorter than dwNtbOutMaxSize, resulting in a short
USB packet instead of a ZLP. But in the case where the NTB length
is exactly dwNtbOutMaxSize and this is an exact multiplum of
wMaxPacketSize, then we must send a ZLP.
This fixes an issue seen on a Sierra Wireless MC7710 device
where the transmission would fail whenever we ended up padding
the NTBs to max size.

Adding support for the MBIM mode in some Sierra Wireless devices.
Some Sierra Wireless firmwares support CDC MBIM but have no CDC
Union funtional descriptor. This violates the MBIM specification,
but we can easily work around the bug by looking at the Interface
Association Descriptor instead. This is most likely what
Windows uses too, which explains how the firmware bug has gone
unnoticed until now.
This change will not affect any currently supported device
conforming to the NCM or MBIM specifications, as they must have
the CDC Union descriptor.

This implements a socket release callback function to check
if the socket cached route got invalid during the time
we owned the socket. The function is used from udp, raw

The route lookup in ipv4_sk_update_pmtu() might return a route
different from the route we cached at the socket. This is because
standart routes are per cpu, so each cpu has it's own struct rtable.
This means that we do not invalidate the socket cached route if the
NET_RX_SOFTIRQ is not served by the same cpu that the sending socket
uses. As a result, the cached route reused until we disconnect.
With this patch we invalidate the socket cached route if possible.
If the socket is owened by the user, we can't update the cached
route directly. A followup patch will implement socket release
callback functions for datagram sockets to handle this case.

splice() can handle pages of any order, but network code tries hard to
split them in PAGE_SIZE units. Not quite successfully anyway, as
__splice_segment() assumed poff < PAGE_SIZE. This is true for
the skb->data part, not necessarily for the fragments.
This patch removes this logic to give the pages as they are in the skb.

The lines
if (mlx4_is_mfunc(dev)) {
nreq = 2;
} else {
which hard code the number of requested msi-x vectors under multi-function
mode to two can be removed completely, since the firmware sets num_eqs and
reserved_eqs appropriately Thus, the code line:
nreq = min_t(int, dev->caps.num_eqs - dev->caps.reserved_eqs, nreq);
is by itself sufficient and correct for all cases. Currently, for mfunc
mode num_eqs = 32 and reserved_eqs = 28, hence four vectors will be enabled.
This triples (one vector is used for the async events and commands EQ) the
horse power provided for processing of incoming packets on netdev RSS scheme,
IO initiators/targets commands processing flows, etc.

Commit 5b4c4d36860e "mlx4_en: Allow communication between functions on
same host" introduced a regression under which a bridge acting as vSwitch
whose uplink is an mlx4 Ethernet device become non-operative in native
(non sriov) mode. This happens since broadcast ARP requests sent by VMs
were loopback-ed by the HW and hence the bridge learned VM source MACs
on both the VM and the uplink ports.
The fix is to place the DMAC in the send WQE only under SRIOV/eSwitch
configuration or when the device is in selftest.

The xgmac driver assumes 1 frame per descriptor. If a frame larger than
the descriptor's buffer size is received, the frame will spill over into
the next descriptor. So check for received frames that span more than one
descriptor and discard them. This prevents a crash if we receive erroneous
large packets.

Jamie Parsons reported a problem recently, in which the re-initalization of an
association (The duplicate init case), resulted in a loss of receive window
space. He tracked down the root cause to sctp_outq_teardown, which discarded
all the data on an outq during a re-initalization of the corresponding
association, but never reset the outq->outstanding_data field to zero. I wrote,
and he tested this fix, which does a proper full re-initalization of the outq,
fixing this problem, and hopefully future proofing us from simmilar issues down
the road.

====================
This batch of fixes is intended for 3.8...
Included is a Bluetooth pull. Gustavo says:
"A few fixes for 3.8. Five of them are just new devices ids addition.
Apart from the that there is fix to a kernel memory leak to userspace from
Anderson Lizardo, two interoperability fixes from Jaganath Kanakkassery and
Szymon Janc. And a crash fix by me."
Along with that, Amitkumar Karwar brings a pair of mwifiex fixes for
problems related to handling of band information within the driver.
These problems can lead to association failures.
Sujith Manoharan fixes a memory leak in the ath9k_htc code (originally
reported by Larry Finger).
The big hero this round is Felix Fietkau. Felix gives us seven
ath9k fixes, including a fix for a race condition, the removal of a
double-free, and a fix for a deadlock, among others.
These have all been in linux-next for at least a couple of days,
with no complaints so far. Please let me know if there are problems!

The commit "ath9k: fix rx flush handling" added a deadlock that happens
because ath_rx_tasklet is called in a section that has already taken the
rx buffer lock.
It seems that the only purpose of the rxbuflock was a band-aid fix to the
reset vs rx tasklet race, which has been properly fixed in the commit
"ath9k: add a better fix for the rx tasklet vs rx flush race".
Now that the fix is in, we can safely remove the lock to avoid such issues.

On hardware reintialization reference count of
already existing timers would be increased again.
This leads to problems on module unloading.

Right now the rx flush is not doing anything useful on AR9003+, as it only
works if the buffers in the rx FIFO have not been purged yet, as is done
by ath_stoprecv.
To fix this, always call ath_flushrecv from within ath_stoprecv before
the FIFO is emptied, but still after the hw receive path has been stopped.
This ensures that frames received (and ACKed by the hardware) shortly before
a reset will be seen by the software, which should improve A-MPDU session
stability.

Ensure that the rx tasklet is no longer running when entering the reset path.
Also remove the distinction between flush and no-flush frame processing.
If a frame has been received and ACKed by the hardware, the stack needs to see
it, so that the BA receive window does not go out of sync.

During teardown, mac80211 will not return a new beacon. This is normal and
handled properly in the driver, so there's no need to spam the user with a kernel
warning here.

When the next beacon is sent, the ath_buf from the previous run is reused.
If getting a new beacon from mac80211 fails, bf->bf_mpdu is not reset, yet
the skb is freed, leading to a double-free on the next beacon tx attempt,
resulting in a system crash.

On AR9300 the rx FIFO needs to be empty during reset to ensure that no
further DMA activity is generated, otherwise it might lead to memory
corruption issues.

SKBs that are allocated in the HTC layer do not have callbacks
registered and hence ended up not being freed, Fix this by freeing
them properly in the TX completion routine.

Currently "adapter->config_bands" is updated during infra
association only if channel is provided by user in "iw connect"
command. config_bands is used while preparing association
request to calculate supported rates by intersecting our rates
with the rates advertised by AP.
There is corner case in which we include zero rates in
supported rates TLV based on previous IBSS network history,
which leads to association failure.
This patch fixes the problem by correctly updating config_bands.

The length parameter should be sizeof(req->name) - 1 because there is no
guarantee that string provided by userspace will contain the trailing
'\0'.
Can be easily reproduced by manually setting req->name to 128 non-zero
bytes prior to ioctl(HIDPCONNADD) and checking the device name setup on
input subsystem:
$ cat /sys/devices/pnp0/00\:04/tty/ttyS0/hci0/hci0\:1/input8/name

After sending reset command wait for its command complete event before
sending next command. Some chips sends CC event for command received
before reset if reset was send before chip replied with CC.
This is also required by specification that host shall not send
additional HCI commands before receiving CC for reset.

Routes with locked mtu should not use learned pmtu informations,
so do not update the pmtu on these routes.

The output route check was introduced with git commit 261663b0
(ipv4: Don't use the cached pmtu informations for input routes)
during times when we cached the pmtu informations on the
inetpeer. Now the pmtu informations are back in the routes,
so this check is obsolete. It also had some unwanted side effects,
as reported by Timo Teras and Lukas Tribus.

Commit 299b0767 (ipv6: Fix IPsec slowpath fragmentation problem)
has introduced a error in the header length calculation that
provokes corrupted packets when non-fragmentable extensions
headers (Destination Option or Routing Header Type 2) are used.
rt->rt6i_nfheader_len is the length of the non-fragmentable
extension header, and it should be substracted to
rt->dst.header_len, and not to exthdrlen, as it was done before
commit 299b0767.
This patch reverts to the original and correct behavior. It has
been successfully tested with and without IPsec on packets
that include non-fragmentable extensions headers.

commit 24b1042c4eb2 ("usbnet: dm9601: apply introduced usb command
APIs") removes the distiction between DM_WRITE_REG and DM_WRITE_REGS
command. The distiction is reintroduced to the driver so that the
functionality of the driver remains same.
