2010-11-09usb: musb: fail unaligned DMA transfers on v1.8 and aboveAnand Gadiyar
The Inventra DMA engine in version 1.8 and later of the MUSB controller cannot handle DMA addresses that are not aligned to a 4 byte boundary. It ends up ignoring the last two bits programmed in the DMA_ADDR register. This is a deliberate design change in the controller and is documented in the programming guide. Earlier versions of the controller could handle these accesses just fine. Fail dma_channel_program if we see an unaligned address when using the newer controllers, so that the caller can carry out the transfer using PIO mode. (Current callers already have this backup path in place).

2010-11-09Bluetooth: Fix non-SSP auth request for HIGH security level socketsJohan Hedberg
When initiating dedicated bonding a L2CAP raw socket with HIGH security level is used. The kernel is supposed to trigger the authentication request in this case but this doesn't happen currently for non-SSP (pre-2.1) devices. The reason is that the authentication request happens in the remote extended features callback which never gets called for non-SSP devices. This patch fixes the issue by requesting also authentiation in the (normal) remote features callback in the case of non-SSP devices. This rule is applied only for HIGH security level which might at first seem unintuitive since on the server socket side MEDIUM is already enough for authentication. However, for the clients we really want to prefer the server side to decide the authentication requrement in most cases, and since most client sockets use MEDIUM it's better to be avoided on the kernel side for these sockets. The important socket to request it for is the dedicated bonding one and that socket uses HIGH security level. The patch is based on the initial investigation and patch proposal from Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.

2010-11-08ath9k_hw: Fix AR9280 surprise removal during frequent idle on/offVasanthakumar Thiagarajan
Bit 22 of AR_WA should be set to fix the situation where chip reset is asynchronous to clock of analog shift registers, such that when reset is released, it could mess up the values of analog shift registers and cause some hw issue on AR9280. This bit is write only, but the driver does a read-modify-write on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave() during radio disable. This causes surprise removal of hw. It can never recover from this state and the hw will become usable only after a power on/off cycle, and sometimes only during a cold reboot. This issue can be triggered by doing frequent roaming with the simple/test-roam script available from the wifi-test project [1] when roaming between APs quickly. When roaming there is a is a high possibility that the device being put into idle (radio disable) state by mac80211 during AUTH->ASSOC. A device hardware reset would fail and the kernel would output: [40251.363799] ath: AWAKE -> FULL-SLEEP [40251.363815] ieee80211 phy17: device no longer idle - working [40251.363817] ath: Marking phy17 as not-idle [40251.363819] ath: FULL-SLEEP -> AWAKE [40251.415978] pciehp 0000:00:1c.3:pcie04: Card not present on Slot(3) [40251.419896] ath: ah->misc_mode 0x4 [40251.428138] pciehp 0000:00:1c.3:pcie04: Card present on Slot(3) [40251.532247] ath: timeout (100000 us) on reg 0x9860: 0xffffffff & 0x00000001 != 0x00000000 [40251.532250] ath: Unable to reset channel (2462 MHz), reset status -5 [40251.532422] ath: Set channel: 5745 MHz [40251.540639] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.548826] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.557023] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.565211] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.573415] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.581603] ath: Failed to stop TX DMA in 100 msec after killing last frame [40251.581606] ath: Failed to stop TX DMA.

2010-11-08libertas: terminate scan when stopping interfaceDaniel Drake
There are currently no provisions in place to ensure that the scanning task has been stopped when the interface is stopped or removed. This can result in a WARNING at net/wireless/core.c:643 and other badness when you remove the module while a scan is happening. Terminate the scanning task during interface stop.

2010-11-08mac80211: unset SDATA_STATE_OFFCHANNEL when cancelling a scanBrian Cavagnolo
For client STA interfaces, ieee80211_do_stop unsets the relevant interface's SDATA_STATE_RUNNING state bit prior to cancelling an interrupted scan. When ieee80211_offchannel_return is invoked as part of cancelling the scan, it doesn't bother unsetting the SDATA_STATE_OFFCHANNEL bit because it sees that the interface is down. Normally this doesn't matter because when the client STA interface is brought back up, it will probably issue a scan. But in some cases (e.g., the user changes the interface type while it is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This prevents the interface queues from being started. So we cancel the scan before unsetting the SDATA_STATE_RUNNING bit. Signed-off-by: Brian Cavagnolo <brian@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-08ath9k: check old power mode before clearing cycle countersFelix Fietkau
ath9k_ps_wakeup() clears the cycle counters after waking up the hardware using ath9k_hw_setpower, however if power save is disabled, then the counters will contain useful data, which then gets discarded.

The HW opmode is blindly set to monitor type on monitor mode change notification. This overrides the opmode when one of the interfaces is still running as non-monitor iftype.

2010-11-08libipw: fix proc entry removalLinus Torvalds
This bug seems to be due to commit 27ae60f8f7aac ("ipw2x00: replace "ieee80211" with "libipw" where appropriate"), where Pavel did this: - libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net); + libipw_proc = proc_mkdir("ieee80211", init_net.proc_net); but then the cleanup was kept as remove_proc_entry(DRV_NAME, init_net.proc_net); in both places (both in the failure case and in the unload case). The error string is also total crap, and says "Unable to create " DRV_NAME " proc directory\n"); Even though it doesn't actually create a proc directory named DRV_NAME at all. So that patch looks like total and utter crap to me. The commit message says "Keep /proc/net/ieee80211 under the original name to avoid breaking user interface." but the thing is, it really didn't fix anything but that one create thing. It needs to fix all the other cases too. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Tested-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: John W.
