b43: fix frequency reported on G-PHY with /new/ firmware

2014-07-09T17:51:20+00:00

commit 2fc68eb122c7ea6cd5be1fe7d6650c0beb2f4f40 upstream. Support for firmware rev 508+ was added years ago, but we never noticed it reports channel in a different way for G-PHY devices. Instead of offset from 2400 MHz it simply passes channel id (AKA hw_value). So far it was (most probably) affecting monitor mode users only, but the following recent commit made it noticeable for quite everybody: commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 Author: Emmanuel Grumbach Date: Tue Mar 4 16:50:13 2014 +0200 cfg80211/mac80211: ignore signal if the frame was heard on wrong channel Reported-by: Aaro Koskinen Signed-off-by: Rafał Miłecki Tested-by: Aaro Koskinen Signed-off-by: John W.

rt2x00: fix rfkill regression on rt2500pci

2014-07-09T17:51:20+00:00

commit 616a8394b5df8c88f4dd416f4527439a4e365034 upstream. As reported by Niels, starting rfkill polling during device probe (commit e2bc7c5, generally sane change) broke rfkill on rt2500pci device. I considered that bug as some initalization issue, which should be fixed on rt2500pci specific code. But after several attempts (see bug report for details) we fail to find working solution. Hence I decided to revert to old behaviour on rt2500pci to fix regression. Additionally patch also unregister rfkill on device remove instead of ifconfig down, what was another issue introduced by bad commit. Bug report: https://bugzilla.kernel.org/show_bug.cgi?id=73821 Fixes: e2bc7c5f3cb8 ("rt2x00: Fix rfkill_polling register function.")

rt2x00: disable TKIP on USB

2014-07-09T17:51:20+00:00

commit 8edcb0ba0d56f5914eef11eda6db8bfe74eb9ca8 upstream. On USB we can not get atomically TKIP key. We have to disable support for TKIP acceleration on USB hardware to avoid bug as showed bellow.

ath9k: protect tid->sched check

2014-06-07T23:02:16+00:00

commit 21f8aaee0c62708654988ce092838aa7df4d25d8 upstream. We check tid->sched without a lock taken on ath_tx_aggr_sleep(). That is race condition which can result of doing list_del(&tid->list) twice (second time with poisoned list node) and cause crash like shown below: [424271.637220] BUG: unable to handle kernel paging request at 00100104 [424271.637328] IP: [] ath_tx_aggr_sleep+0x62/0xe0 [ath9k] ...

b43: ensue that BCMA is "y" when B43 is "y"

2014-06-07T23:02:14+00:00

commit 693026ef2e751fd94d2e6c71028e68343cc875d5 upstream. When b43 gets build into the kernel and it should use bcma we have to ensure that bcma was also build into the kernel and not as a module. In this patch this is also done for SSB, although you can not build b43 without ssb support for now.

rt2800usb: Add support for 2001:3c1e (D-Link DWA-125 rev B1) USB Wi-Fi adapter

2014-06-07T23:02:13+00:00

commit fd7b9270120ca7e53fbf0469febe0c68acf6a0a2 upstream. D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a Ralink chipset supported by the rt2800usb driver. Currently, to work around the problem (it's missing in all present kernel versions, up to and including 3.7.x), I had to add this to /etc/rc.local: echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id After that, the device works without problems. Been using it for over a week with no bugs in sight. The attached patch is trivial and simply adds the new USB ID to the list of devices handled by rt2800usb.
