commit 10cbc1d97a7c7f9ae862fffe27b771ef0da9c461 upstream.
Newer firmware versions for the Pantech UML290 use a different
subclass ID. The Windows driver match on both IDs, so we do
that as well.
The ZTE (Vodafone) K5006-Z is a new device.

commit 9b469a60d68b13c288d5c3fc23de29d9d482dbe6 upstream.
Add 6 new devices and one modified device, based on
information from laptop vendor Windows drivers.
Sony provides a driver with two new devices using
a Gobi 2k+ layout (1199:68a5 and 1199:68a9). The
Sony driver also adds a non-standard QMI/net
interface to the already supported 1199:9011
Gobi device. We do not know whether this is an
alternate interface number or an additional
interface which might be present, but that doesn't
really matter.
Lenovo provides a driver supporting 4 new devices:
- MC7770 (1199:901b) with standard Gobi 2k+ layout
- MC7700 (0f3d:68a2) with layout similar to MC7710
- MC7750 (114f:68a2) with layout similar to MC7710
- EM7700 (1199:901c) with layout similar to MC7710
Note regaring the three devices similar to MC7710:
The Windows drivers only support interface #8 on these
devices. The MC7710 can support QMI/net functions on
interface #19 and #20 as well, and this driver is
verified to work on interface #19 (a firmware bug is
suspected to prevent #20 from working).
We do not enable these additional interfaces until they
either show up in a Windows driver or are verified to
work in some other way. Therefore limiting the new
devices to interface #8 for now.

commit 28889b7e7818342f6c254e27b9b2c68702ab867a upstream.
This patch fixes a build failure introduced in commit 66636287
("gianfar: Support the get_ts_info ethtool method."). Not only was a
global variable inconsistently named, but also it was not exported as
it should have been.
This fix is also needed in stable version 3.5.

commit 94543a8d4fb302817014981489f15cb3b92ec3c2 upstream.
iwl_dbgfs_fh_reg_read() can cause crashes and/or
BUG_ON in slub because the ifdefs are wrong, the
code in iwl_dump_fh() should use DEBUGFS, not
DEBUG to protect the buffer writing code.
Also, while at it, clean up the arguments to the
function, some code and make it generally safer.

commit efd5d6b03bd9c9e0df646c56fb5f4f3e25e5c1ac upstream.
On our system (ARM Cortex-M3 SOC running linux-2.6.33)
frequent crashes were observed in the rt2800usb module
because of the invalid length of the received packet (3392,
46920...). This patch adds the sanity check on the packet
legth. Also, changed WARNING to ERROR in rt2x00lib_rxdone()
so that the bad packet condition would be noticed.
The fix was tested on the latest compat-wireless-3.5.1-1-snpc.

commit a396e10019eaf3809b0219c966865aaafec12630 upstream.
We need to program the rfkill switch GPIO pin direction to input at
device initialization time, not only when the interface is brought up.
Doing this only when the interface is brought up could lead to rfkill
detecting the switch is turned on erroneously and inability to create
the interface and bringing it up.

commit ab04c8bd423edb03e2148350a091836c196107fc upstream.
This patch fixes an oops which occurs when unloading the driver, while the
network interface is still up. The problem is that first the io mapping is
teared own, then the CAN device is unregistered, resulting in accessing the

commit 022e1d0680c7b4366017393417b8758be5abcee8 upstream.
There are a number of problems that occur for the latest version
of the Realtek RTL8188CE device with the in-kernel driver. These
include selection of the wrong firmware, and system lockup. A full
fix is known, but is too invasive for inclusion in stable. This patch
fixes the problem with loading the wrong firmware, and logs a message
that the device may not work for kernels 3.6 and older.

commit d90c92fee89ccd75ef2646f3bde0b4c0450666c3 upstream.
This patch fixes a bug found by Nish Aravamudan
(https://lkml.org/lkml/2012/5/15/220) where the driver is not following
the spec (it is not aligning the rx buffer on a 16-byte boundary) and the
hypervisor aborts the registration, making the device unusable.
The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461)
to replace the kmalloc+map for a single call to dma_alloc_coherent()
because that function always aligns to a 16-byte boundary.
The stable trees will run into this bug whenever the rx buffer kmalloc call
returns something not aligned on a 16-byte boundary.

commit 85e87870fa18ec9f5df98e2d3b48f3699560a570 upstream.
Suspending an open usbnet device results in constant
rescheduling of usbnet_bh.
commit 65841fd5 "usbnet: handle remote wakeup asap"
refactored the usbnet_bh code to allow sharing the
urb allocate and submit code with usbnet_resume. In
this process, a test for, and immediate return on,
ENOLINK from rx_submit was unintentionally dropped.
The rx queue will not grow if rx_submit fails,
making usbnet_bh reschedule itself. This results
in a softirq storm if the error is persistent.
rx_submit translates the usb_submit_urb error
EHOSTUNREACH into ENOLINK, so this is an expected
and persistent error for a suspended device. The
old code tested for this condition and avoided
rescheduling. Putting this test back.

The MCP2515 has a silicon bug causing repeated frame transmission, see section
5 of MCP2515 Rev. B Silicon Errata Revision G (March 2007).
Basically, setting TXBnCTRL.TXREQ in either SPI mode (00 or 11) will eventually
cause the bug. The workaround proposed by Microchip is to use mode 00 and send
a RTS command on the SPI bus to initiate the transmission.

[ Upstream commit 7e6d06f0de3f74ca929441add094518ae332257c ]
Currently an skb requiring TSO may not fit within a minimum-size TX
queue. The TX queue selected for the skb may stall and trigger the TX
watchdog repeatedly (since the problem skb will be retried after the
TX reset). This issue is designated as CVE-2012-3412.
Set the maximum number of TSO segments for our devices to 100. This
should make no difference to behaviour unless the actual MSS is less
than about 700. Increase the minimum TX queue size accordingly to
allow for 2 worst-case skbs, so that there will definitely be space
to add an skb after we wake a queue.
To avoid invalidating existing configurations, change
efx_ethtool_set_ringparam() to fix up values that are too small rather
than returning -EINVAL.

commit d821a4c4d11ad160925dab2bb009b8444beff484 upstream.
With a low enough MSS on the link partner and TSO enabled locally, the
networking stack can periodically send a very large (e.g. 64KB) TCP
message for which the driver will attempt to use more Tx descriptors than
are available by default in the Tx ring. This is due to a workaround in
the code that imposes a limit of only 4 MSS-sized segments per descriptor
which appears to be a carry-over from the older e1000 driver and may be
applicable only to some older PCI or PCIx parts which are not supported in
e1000e. When the driver gets a message that is too large to fit across the
configured number of Tx descriptors, it stops the upper stack from queueing
any more and gets stuck in this state. After a timeout, the upper stack
assumes the adapter is hung and calls the driver to reset it.
Remove the unnecessary limitation of using up to only 4 MSS-sized segments
per Tx descriptor, and put in a hard failure test to catch when attempting
to check for message sizes larger than would fit in the whole Tx ring.
Refactor the remaining logic that limits the size of data per Tx descriptor
from a seemingly arbitrary 8KB to a limit based on the dynamic size of the
Tx packet buffer as described in the hardware specification.
Also, fix the logic in the check for space in the Tx ring for the next
largest possible packet after the current one has been successfully queued
for transmit, and use the appropriate defines for default ring sizes in
e1000_probe instead of magic values.
This issue goes back to the introduction of e1000e in 2.6.24 when it was
split off from e1000.

commit ab6f148de28261682d300662e87b9477f7efc95b upstream.
A usbnet device can share a multifunction device
with a storage device. If the storage device is autoresumed
the usbnet devices also needs to be autoresumed. Allocating
memory with GFP_KERNEL can deadlock in this case.
This should go back into all kernels that have

commit e1352fde5682ab1bdd2a9e5d75c22d1fe210ef77 upstream.
ath_rx_tasklet() calls ath9k_rx_skb_preprocess() and ath9k_rx_skb_postprocess()
in a loop over the received frames. The decrypt_error flag is
initialized to false
just outside ath_rx_tasklet() loop. ath9k_rx_accept(), called by
ath9k_rx_skb_preprocess(),
only sets decrypt_error to true and never to false.
Then ath_rx_tasklet() calls ath9k_rx_skb_postprocess() and passes
decrypt_error to it.
So, after a decryption error, in ath9k_rx_skb_postprocess(), we can
have a leftover value
from another processed frame. In that case, the frame will not be marked with
RX_FLAG_DECRYPTED even if it is decrypted correctly.
When using CCMP encryption this issue can lead to connection stuck
because of CCMP
PN corruption and a waste of CPU time since mac80211 tries to decrypt an already
deciphered frame with ieee80211_aes_ccm_decrypt.
Fix the issue initializing decrypt_error flag at the begging of the
ath_rx_tasklet() loop.

commit 50e2a30cf6fcaeb2d27360ba614dd169a10041c5 upstream.
There's a bug that causes the rate scaling to get stuck
when it has to use single-stream rates with a peer that
can do GF and SGI; the two are incompatible so we can't
use them together, but that causes the algorithm to not
work at all, it always rejects updates.
Disable greenfield for now to prevent that problem.

commit 66d1b9263a371abd15806c53f486f0645ef31a8f upstream.
This is a fix for bug, introduced in 3.4 kernel by commit
1ab5ecb90cb6a3df1476e052f76a6e8f6511cb3d ("tun: don't hold network
namespace by tun sockets"), which, among other things, replaced simple
sock_put() by sk_release_kernel(). Below is sequence, which leads to
oops for non-persistent devices:
tun_chr_close()
tun_detach() <== tun->socket.file = NULL
tun_free_netdev()
sk_release_sock()
sock_release(sock->file == NULL)
iput(SOCK_INODE(sock)) <== dereference on NULL pointer
This patch just removes zeroing of socket's file from __tun_detach().
sock_release() will do this.

commit d4e5979c0da95791aa717c18e162540c7a596360 upstream.
AR1111 is same as AR9485. The h/w
difference between them is quite insignificant,
Felix suggests only very few baseband features
may not be available in AR1111. The h/w code for
AR9485 is already present, so AR1111 should
work fine with the addition of its PID/VID.

[ Upstream commit e4c7f259c5be99dcfc3d98f913590663b0305bf8 ]
The problem is that we call this with a spin lock held. The call tree
is:
kaweth_start_xmit() holds kaweth->device_lock.
-> kaweth_async_set_rx_mode()
-> kaweth_control()
-> kaweth_internal_control_msg()
The kaweth_internal_control_msg() function is only called from
kaweth_control() which used GFP_ATOMIC for its allocations.

commit fe020120cb863ba918c6d603345342a880272c4d upstream.
mwifiex driver supports 2x2 chips as well. Hence valid mcs values
are 0 to 15. The check for mcs index is corrected in this patch.
For example: if 40MHz is enabled and mcs index is 11, "iw link"
command would show "tx bitrate: 108.0 MBit/s" without this patch.
Now it shows "tx bitrate: 108.0 MBit/s MCS 11 40Mhz" with the patch.

commit f1b00f4dab29b57bdf1bc03ef12020b280fd2a72 upstream.
Commit d83579e2a50ac68389e6b4c58b845c702cf37516 incorporated some
changes from the vendor driver that made it newly important that the
calculated hardware version correctly include the CHIP_92D bit, as all
of the IS_92D_* macros were changed to depend on it. However, this bit
was being unset for dual-mac, dual-phy devices. The vendor driver
behavior was modified to not do this, but unfortunately this change was
not picked up along with the others. This caused scanning in the 2.4GHz
band to be broken, and possibly other bugs as well.
This patch brings the version calculation logic in parity with the
vendor driver in this regard, and in doing so fixes the regression.
However, the version calculation code in general continues to be largely
incoherent and messy, and needs to be cleaned up.

commit 3ce4d85b76010525adedcc2555fa164bf706a2f3 upstream.
In commit a7959c1, the USB part of rtlwifi was switched to convert
_usb_read_sync() to using a preallocated buffer rather than one
that has been acquired using kmalloc. Although this routine is named
as though it were synchronous, there seem to be simultaneous users,
and the selection of the index to the data buffer is not multi-user
safe. This situation is addressed by adding a new spinlock. The routine
cannot sleep, thus a mutex is not allowed.
