iwlwifi: fix unloading driver while scanning

2009-10-05T16:33:11+00:00

This is commit 5bddf54962bf68002816df710348ba197d6391bb in linux-2.6.

If NetworkManager is busy scanning when user
tries to unload the module, the driver can not be unloaded
because HW still scanning.

Make sure driver sends abort scan host command to uCode if it
is in the middle of scanning during driver unload.

iwlwifi: traverse linklist to find the valid OTP block

2009-10-05T16:33:11+00:00

commit 415e49936b4b29b34c2fb561eeab867d41fc43a6 upstream.

For devices using OTP memory, EEPROM image can start from
any one of the OTP blocks. If shadow RAM is disabled, we need to
traverse link list to find the last valid block, then start the EEPROM
image reading.

If OTP is not full, the valid block is the block _before_ the last block
on the link list; the last block on the link list is the empty block
ready for next OTP refresh/update.

If OTP is full, then the last block is the valid block to be used for
configure the device.

iwlagn: modify digital SVR for 1000

2009-10-05T16:33:10+00:00

commit 02c06e4abc0680afd31bf481a803541556757fb6 upstream.

On 1000, there are two Switching Voltage Regulators (SVR). The first one
apply digital voltage level (1.32V) for PCIe block and core. We need to
use this regulator to solve a stability issue related to noisy DC2DC
line in the silicon.

iwlwifi: Handle new firmware file with ucode build number in header

2009-10-05T16:33:09+00:00

commit cc0f555d511a5fe9d4519334c8f674a1dbab9e3a upstream.

Adding new API version to account for change to ucode file format.  New
header includes the build number of the ucode.  This build number is the
SVN revision thus allowing for exact correlation to the code that
generated it.

The header adds the build number so that older ucode images can also be
enhanced to include the build in the future.

some cleanup in iwl_read_ucode needed to ensure old header not used and
reduce unnecessary references through pointer with the data is already
in heap variable.

commit 0d0cd72fa1e6bfd419c99478ec70b4877ed0ef86 upstream.

Paraphrasing Rafael J. Wysocki: "drivers should not release PCI IRQs
in suspend."  Doing so causes a warning during suspend/resume on some
platforms.

* Don't put chip to full sleep because there are problems during
   wakeup. Instead hold MAC/Baseband on warm reset state via a new
   function ath5k_hw_on_hold.

 * Minor cleanups

can: fix NOHZ local_softirq_pending 08 warning

2009-10-05T16:32:13+00:00

commit 481a8199142c050b72bff8a1956a49fd0a75bbe0 upstream.

When using nanosleep() in an userspace application we get a ratelimit warning

NOHZ: local_softirq_pending 08

for 10 times.

The echo of CAN frames is done from process context and softirq context only.
Therefore the usage of netif_rx() was wrong (for years).

This patch replaces netif_rx() with netif_rx_ni() which has to be used from
process/softirq context. It also adds a missing comment that can_send() must
no be used from hardirq context.

kaweth: Fix memory leak in kaweth_control()

2009-10-05T16:31:58+00:00

commit 051b982bcc620695de629d29c333c95b66e9b95e upstream.

kaweth_control() never frees the buffer that it allocates for the USB
control message.  Test case:

while :; do ifconfig eth2 down ; ifconfig eth2 up ; done

This is a tiny buffer so it is a slow leak.  If you want to speed up the
process, you can change the allocation size to e.g. 16384 bytes, and it
will consume several megabytes within a few minutes.
