rt2x00: Fix sleep-while-atomic bug in powersaving code.

2011-11-26T17:08:34+00:00

commit ed66ba472a742cd8df37d7072804b2111cdb1014 upstream.

The generic powersaving code that determines after reception of a frame
whether the device should go back to sleep or whether is could stay
awake was calling rt2x00lib_config directly from RX tasklet context.
On a number of the devices this call can actually sleep, due to having
to confirm that the sleeping commands have been executed successfully.

Fix this by moving the call to rt2x00lib_config to a workqueue call.

Net, libertas: Resolve memory leak in if_spi_host_to_card()

2011-11-26T17:08:34+00:00

commit fe09b32a4361bea44169b2063e8c867cabb6a8ba upstream.

If we hit the default case in the switch in if_spi_host_to_card() we'll leak
the memory we allocated for 'packet'. This patch resolves the leak by freeing
the allocated memory in that case.

ath9k_hw: Fix regression of register offset for AR9003 chips

2011-11-11T17:44:48+00:00

commit 52d6d4ef5e6d1517688e27c11c01ab303ec681dd upstream.

My recent commits (3782c69d, 324c74a) introduced regression
for register offset selection that based on the macversion.
Not using parentheses in proper manner for ternary operator
leads to select wrong offset for the registers.

This issue was observed with AR9462 chip that immediate disconnect
after the association with the following message

ieee80211 phy3: wlan0: Failed to send nullfunc to AP 00:23:69:12:ea:47
after 500ms, disconnecting.

dp83640: use proper function to free transmit time stamping packets

2011-11-11T17:44:48+00:00

commit f5ff7cd1a84caa9545d952a37ac872ccb73825fb upstream.

The previous commit enforces a new rule for handling the cloned packets
for transmit time stamping. These packets must not be freed using any other
function than skb_complete_tx_timestamp. This commit fixes the one and only
driver using this API.

The driver first appeared in v3.0.

tg3: fix tigon3_dma_hwbug_workaround()

[ Upstream commit f7ff19871bb4a3451e1ca2cf660bf633018cfbec ]

Ari got kernel panics using tg3 NIC, and bisected to 2669069aacc9 "tg3:
enable transmit time stamping."

This is because tigon3_dma_hwbug_workaround() might alloc a new skb and
free the original. We panic when skb_tx_timestamp() is called on freed
skb.

iwlagn: do not use interruptible waits

2011-11-11T17:43:34+00:00

commit effd4d9aece9184f526e6556786a94d335e38b71 upstream.

Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.

This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.

Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.

This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in  'REPLY_SCAN_ABORT_CMD'

I have seen in P2P testing, but it is likely
that there are other errors caused by this.
