ath9k: Fix tx throughput drops for AR9003 chips with AES encryption

2011-08-03T19:42:37+00:00

commit 4f6760b01bda625e9555e16d8e9ba8126a9c9498 upstream.

While sending aggregated frames in AES, the AR5416 chips
required additional padding b/w subframes. This workaround
is not needed for edma (AR9003 family) chips. With this patch
~4Mbps thoughput improvement was observed in clear environment.

iwlagn: fix change_interface for P2P types

2011-07-09T06:15:33+00:00

commit 5306c0807491e891125f4fb08b04340c91530f57 upstream.

When an interface changes type to a P2P type,
iwlagn will erroneously set vif->type to the
P2P type and not the reduced/split type. Fix
this by keeping "newtype" in another variable
for the assignment to vif->type.

6pack,mkiss: fix lock inconsistency

2011-07-09T06:15:33+00:00

commit 6e4e2f811bade330126d4029c88c831784a7efd9 upstream.

Lockdep found a locking inconsistency in the mkiss_close function:

> kernel: [ INFO: inconsistent lock state ]
> kernel: 2.6.39.1 #3
> kernel: ---------------------------------
> kernel: inconsistent {IN-SOFTIRQ-R} -> {SOFTIRQ-ON-W} usage.
> kernel: ax25ipd/2813 [HC0[0]:SC0[0]:HE1:SE1] takes:
> kernel: (disc_data_lock){+++?.-}, at: [] mkiss_close+0x1b/0x90 [mkiss]
> kernel: {IN-SOFTIRQ-R} state was registered at:

The message hints that disc_data_lock is aquired with softirqs disabled,
but does not itself disable softirqs, which can in rare circumstances
lead to a deadlock.
The same problem is present in the 6pack driver, this patch fixes both
by using write_lock_bh instead of write_lock.

ath9k: Fix suspend/resume when no interface is UP

2011-07-09T06:15:10+00:00

commit c31eb8e926835582cd186b33a7a864880a4c0c79 upstream.

When no interface has been brought up, the chip's power
state continued as AWAKE. So during resume, the chip never
been powered up.

pxa168_eth: fix race in transmit path.

commit 384420409d9b5d4443940abace49363d26135412 upstream.

Because the socket buffer is freed in the completion interrupt, it is not
safe to access it after submitting it to the hardware.

ath5k: Disable fast channel switching by default

2011-07-09T06:15:10+00:00

commit a99168eece601d2a79ecfcb968ce226f2f30cf98 upstream.

Disable fast channel change by default on AR2413/AR5413 due to
some bug reports (it still works for me but it's better to be safe).
Add a module parameter "fastchanswitch" in case anyone wants to enable
it and play with it.
