commit ac45c12dfb upstream.
There are few places where we are checking for macversion and revsions
before RTC is powered ON. However we are reading the macversion and
revisions only after RTC is powered ON and so both macversion and
revisions are actully zero and this leads to incorrect srev checks
Incorrect srev checks can cause registers to be configured wrongly and can
cause unexpected behavior. Fixing this seems to address the ASPM issue that
we have observed. The laptop becomes very slow and hangs mostly with ASPM L1
enabled without this fix.
fix this by reading the macversion and revisisons even before we start
using them. There is no reason why should we delay reading this info
until RTC is powered on as this is just a register information.

commit 4e5518ca53 upstream.
pcmcia_request_irq() and pcmcia_enable_device() are intended
to be called from process context (first function allocate memory
with GFP_KERNEL, second take a mutex). We can not take spin lock
and call them.
It's safe to move spin lock after pcmcia_enable_device() as we
still hold off IRQ until dev->base_addr is 0 and driver will
not proceed with interrupts when is not ready.

In these situations, you are usually trying to connect to a new AP, so
keeping TKIP countermeasures active is confusing. This is already how

commit 0a54917c3f upstream.
Enable the port when disabling countermeasures, and disable it on
enabling countermeasures.
This bug causes the response of the system to certain attacks to be
ineffective.
It also prevents wpa_supplicant from getting scan results, as
wpa_supplicant disables countermeasures on startup - preventing the
hardware from scanning.
wpa_supplicant works with ap_mode=2 despite this bug because the commit
handler re-enables the port.
The log tends to look like:

commit 6ccf15a1a7 upstream.
Atheros PCIe wireless cards handled by ath5k do require L0s disabled.
For distributions shipping with CONFIG_PCIEASPM (this will be enabled
by default in the future in 2.6.36) this will also mean both L1 and L0s
will be disabled when a pre 1.1 PCIe device is detected. We do know L1
works correctly even for all ath5k pre 1.1 PCIe devices though but cannot
currently undue the effect of a blacklist, for details you can read
pcie_aspm_sanity_check() and see how it adjusts the device link
capability.
It may be possible in the future to implement some PCI API to allow
drivers to override blacklists for pre 1.1 PCIe but for now it is
best to accept that both L0s and L1 will be disabled completely for
distributions shipping with CONFIG_PCIEASPM rather than having this
issue present. Motivation for adding this new API will be to help
with power consumption for some of these devices.
Example of issues you'd see:
- On the Acer Aspire One (AOA150, Atheros Communications Inc. AR5001
Wireless Network Adapter [168c:001c] (rev 01)) doesn't work well
with ASPM enabled, the card will eventually stall on heavy traffic
with often 'unsupported jumbo' warnings appearing. Disabling
ASPM L0s in ath5k fixes these problems.
- On the same card you would see a storm of RXORN interrupts
even though medium is idle.

We do not need to synchronize when canceling priv->scan_check work.
We can avoid races (sending double abort command or send no
command at all) using STATUS_SCAN_ABORT bit. Moreover
current iwl_bg_scan_check() code seems to be broken, as

commit f860d526eb upstream.
When issuing a reset, the TSF value is lost in the hardware because of
the 913x specific cold reset. As with some AR9280 cards, the TSF needs
to be preserved in software here.
Additionally, there's an issue that frequently prevents a successful
TSF write directly after the chip reset. In this case, repeating the
TSF write after the initval-writes usually works.
This patch detects failed TSF writes and recovers from them, taking
into account the delay caused by the initval writes.

commit b561e8274f upstream.
The flow id (scd_flow) in a compressed BA packet should match the txq_id
of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:
[ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected
[ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0),
index 5, is out of range [0-256] 7 7.
And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the
code is operating in a wrong tx queue!

commit 9637e516d1 upstream.
Jumbo frames are not supported, and if they are seen it is likely
a bogus frame so just silently discard them instead of warning on
them all time. Also, instead of dropping them immediately though
move the check *after* we check for all sort of frame errors. This
should enable us to discard these frames if the hardware picks
other bogus items first. Lets see if we still get those jumbo
counters increasing still with this.
Jumbo frames would happen if we tell hardware we can support
a small 802.11 chunks of DMA'd frame, hardware would split RX'd
frames into parts and we'd have to reconstruct them in software.
This is done with USB due to the bulk size but with ath5k we
already provide a good limit to hardware and this should not be
happening.
This is reported quite often and if it fills the logs then this
needs to be addressed and to avoid spurious reports.

Johannes' patch 34e8950 titled:

changed the way mac80211 adds and removes peers. The new
sta_add() / sta_remove() callbacks allowed the driver callbacks
to sleep. Johannes also ported ath9k to use sta_add() / sta_remove()
via the patch 4ca7786 titled:
ath9k: convert to new station add/remove callbacks
but this patch forgot to address a change in locking issue which
Ming Lei eventually found on his 2.6.33-wl #12 build. The 2.6.33-wl
build includes code for the 802.11 subsystem for 2.6.34 though so did
already have the above two patches (ath9k_sta_remove() on his trace),
the 2.6.33 kernel did not however have these two patches. Ming eventually
cured his lockdep warnign via the patch a9f042c titled:
ath9k: fix lockdep warning when unloading module
This went in to 2.6.34 and although it was not marked as a stable
fix it did get trickled down and applied on both 2.6.33 and 2.6.32.
In review, the culprits:
mac80211: allow station add/remove to sleep

v2.6.34-rc1~233^2~49^2~10

This last one trickled down to 2.6.33 (OK), 2.6.33 (invalid) and 2.6.32 (invalid).

The patch titled "ath9k: fix lockdep warning when unloading module"

ath9k 0000:16:00.0: PCI INT A disabled
The original lockdep fixed an issue where due to the new changes
the driver was not disabling the bottom halves but it is incorrect
to do this on the older kernels since IRQs are already disabled.

commit 93a59d7527 upstream.
James Grossmann [1] reported that p54 spews out confusing
messages instead of preventing the mayhem from happening.
the reason is that "p54: generate channel list dynamically"
is not perfect. It didn't discard incomplete channel data
sets and therefore p54 advertised to support them as well.
