commit 414b7e3b9ce8b0577f613e656fdbc36b34b444dd upstream.
The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to
usb_control_msg() with a timeout value of 0. In some instances where the
interface is shutting down, this infinite wait results in a CPU deadlock. A
one second timeout fixes this problem without affecting any normal operations.
This bug is reported at https://bugzilla.novell.com/show_bug.cgi?id=927786.

commit a3fa71c40f1853d0c27e8f5bc01a722a705d9682 upstream.
In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number. This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data). Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.
This bug has been found by adding a __printf attribute to
wl1271_format_buffer. gcc complained about "format '%u' expects
argument of type 'unsigned int', but argument 5 has type 'u32 *'".

commit 9c8928f5176766bec79f272bd47b7124e11cccbd upstream.
The assumption before this patch was that we don't need to
run again the INIT firmware after the system booted. The
INIT firmware runs calibrations which impact the physical
layer's behavior.
Users reported that it may be helpful to run these
calibrations again every time the interface is brought up.
The penatly is minimal, since the calibrations run fast.
This fixes:

Kernel panic - not syncing: Fatal exception
Jason's analysis:
"The GCC 4.8.1 compiler will not do the for-loop till scat_entries, instead,
it only run one round loop. This may be caused by that the GCC 4.8.1 thought
that the scat_list only have one item and then no need to do full iteration,
but this is simply wrong by looking at the assebly code. This will cause the sg
buffer not get set when scat_entries > 1 and thus lead to kernel panic.
Note: This issue not observed with GCC 4.7.2, only found on the GCC 4.8.1)"
Fix this by using the normal [0] style for defining unknown number of list
entries following the struct. This also fixes corruption with scat_q_depth, which
was mistankely added to the end of struct and overwritten if there were more
than item in the scat list.

commit 8bfae4f9938b6c1f033a5159febe97e441d6d526 upstream.
Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.
The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.
This patch partially reverts the commit 1846ac3dbec0 ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().
I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.
Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

commit 5523d11cc46393a1e61b7ef4a0b2d4e7ed9521e4 upstream.
We don't really need to use different mac colors when adding mac
contexts, because they're not used anywhere. In fact, the firmware
doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401
when we reach that.
Remove the color increment to use always zero and avoid reaching 255.

commit cd8f438405032ac8ff88bd8f2eca5e0c0063b14b upstream.
The base address of the scheduler in the device's memory
(SRAM) comes from two different sources. The periphery
register and the alive notification from the firmware.
We have a check in iwl_pcie_tx_start that ensures that
they are the same.
When we resume from WoWLAN, the firmware may have crashed
for whatever reason. In that case, the whole device may be
reset which means that the periphery register will hold a
meaningless value. When we come to compare
trans_pcie->scd_base_addr (which really holds the value we
had when we loaded the WoWLAN firmware upon suspend) and
the current value of the register, we don't see a match
unsurprisingly.
Trick the check to avoid a loud yet harmless WARN.
Note that when the WoWLAN has crashed, we will see that
in iwl_trans_pcie_d3_resume which will let the op_mode
know. Once the op_mode is informed that the WowLAN firmware
has crashed, it can't do much besides resetting the whole
device.

commit cfd9167af14eb4ec21517a32911d460083ee3d59 upstream.
RT2800 and newer hardware require padding between header and payload if
header length is not multiple of 4.
For historical reasons we also align payload to to 4 bytes boundary, but
such alignment is not needed on modern H/W.
Patch fixes skb_under_panic problems reported from time to time:
https://bugzilla.kernel.org/show_bug.cgi?id=84911
https://bugzilla.kernel.org/show_bug.cgi?id=72471
http://marc.info/?l=linux-wireless&m=139108549530402&w=2
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591
Panic happened because we eat 4 bytes of skb headroom on each
(re)transmission when sending frame without the payload and the header
length not being multiple of 4 (i.e. QoS header has 26 bytes). On such
case because paylad_aling=2 is bigger than header_align=0 we increase
header_align by 4 bytes. To prevent that we could change the check to:
if (payload_length && payload_align > header_align)
header_align += 4;
but not aligning payload at all is more effective and alignment is not
really needed by H/W (that has been tested on OpenWrt project for few
years now).

commit 4e6ce4dc7ce71d0886908d55129d5d6482a27ff9 upstream.
Based on the reference clock, which could be 25MHz or 40MHz,
AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550.
But, when a chip reset is done, processing the initvals
sets the register back to the default value.
Fix this by moving the code in ath9k_hw_init_pll() to
ar9003_hw_override_ini(). Also, do this override for AR9531.

commit 9180ac50716a097a407c6d7e7e4589754a922260 upstream.
The LTR is the handshake between the device and the root
complex about the latency allowed when the bus exits power
save. This configuration was missing and this led to high
latency in the link power up. The end user could experience
high latency in the network because of this.

commit 805dbe17d1c832ad341f14fae8cedf41b67ca6fa upstream.
The driver is not released when ieee80211_register_hw fails in
mac80211_hwsim_create_radio, leading to the access to the unregistered (and
possibly freed) device in platform_driver_unregister:

Two bits control TX power on BBP_R1 register. Correct the mask,
otherwise we clear additional bit on BBP_R1 register, what can have
unknown, possible negative effect.

commit 87c4790330810fe5caf0172d9320cf24ef19cebe upstream.
The firmware notifies about interface changes through the IF event
which has a NO_IF flag that means host can ignore the event. This
behaviour was introduced in the driver by:
commit 2ee8382fc6c763c76396a6aaff77a27089eed3aa

brcmfmac: ignore IF event if firmware indicates it
It turns out that the IF event for the P2P_DEVICE also has this
flag set, but the event should not be ignored in this scenario.
The mentioned commit caused a regression in 3.12 kernel in creation
of the P2P_DEVICE interface.

commit aa11bbf3df026d6b1c6b528bef634fd9de7c2619 upstream.
Using the LQ table which is initially set according to
the rssi could lead to EAPOLs being sent in high legacy
rates like 54mbps.
It's better to avoid sending EAPOLs in high rates as it reduces
the chances of a successful 4-Way handshake.
Avoid this and treat them like other mgmt frames which would
initially get sent at the basic rate.

commit 86974bff066dd8b98be46d7c7d3aba89034f0833 upstream.
This code was broken on big endian systems. Sparse didn't
catch the bug since the firmware command was not tagged as
little endian.
Fix the bug for big endian systems and tag the field in the
firmware command to prevent such issues in the future.

commit 671796dd96b6cd85b75fba9d3007bcf7e5f7c309 upstream.
The driver assumes that endpoint 4 is always an interrupt endpoint.
Unfortunately the type differs between high-speed and full-speed
configurations while in the former case it is indeed an interrupt
endpoint this is not true for the latter case - here it is a bulk
endpoint. When sending URBs with the wrong type the kernel will
generate a warning message including backtrace. In this specific
case there will be a huge amount of warnings which can bring the system
to freeze.
To fix this we are now sending URBs to endpoint 4 using the type
found in the endpoint descriptor.
A side note: The carl9170 firmware currently specifies endpoint 4 as
interrupt endpoint even in the full-speed configuration but this has
no relevance because before this firmware is loaded the endpoint type
is as described above and after the firmware is running the stick is not
reenumerated and so the old descriptor is used.

commit c01fac1c77a00227f706a1654317023e3f4ac7f0 upstream.
If an aggregation session fails, frames still end up in the driver queue
with IEEE80211_TX_CTL_AMPDU set.
This causes tx for the affected station/tid to stall, since
ath_tx_get_tid_subframe returning packets to send.
Fix this by clearing IEEE80211_TX_CTL_AMPDU as long as no aggregation
session is running.

commit dc271ee0d04d12d6bfabacbec803289a7072fbd9 upstream.
Firmware folks seem say that this flag can make trouble.
Drop it. The advantage of CTS to self is that it slightly
reduces the cost of the protection, but make the protection
less reliable.
