commit ff8f59b5 upstream. When doing a channel change, the pending URBs have to be killed properly on calling htc_stop(). This fixes the probe response timeout seen when sending UDP traffic at a high rate and running background scan at the same time. Signed-off-by:

commit 3dd823e6 upstream. With commit 554d1d02 only one RF_KILL interrupt will be seen by the driver when the interface is down. Re-enable the interrupt when it occurs to see all transitions. Signed-off-by:

commit 554d1d02 upstream. Since commit 6cd0b1cb "iwlagn: fix hw-rfkill while the interface is down", we enable interrupts when device is not ready to receive them. However hardware, when it is in some inconsistent state, can generate other than rfkill interrupts and crash the system. I can reproduce crash with "kernel BUG at drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing firmware restarts. To fix only enable rfkill interrupt when down device and after probe. I checked patch on laptop with 5100 device, rfkill change is still passed to user space when device is down. Signed-off-by:

commit eb3e554b upstream. Some drivers (e.g. ath9k) do not always disable beacons when they're supposed to. When an interface is changed using the change_interface op, the mode specific sdata part is in an undefined state and trying to get a beacon at this point can produce weird crashes. To fix this, add a check for ieee80211_sdata_running before using anything from the sdata. Signed-off-by:

commit 82694f76 upstream. When the buffer size is set to zero in the block ack parameter set field, we should use the maximum supported number of subframes. The existing code was bogus and was doing some unnecessary calculations that lead to wrong values. Thanks Johannes for helping me figure this one out.

commit 919bbad5 upstream. Commit b51aff05 said: Under memory pressure, the mac80211 mesh code may helpfully print a message that it failed to clone a mesh frame and then will proceed to crash trying to use it anyway. Fix that. Avoid the reference whenever the frame copy is unsuccessful regardless of the debug message being suppressed or printed. Signed-off-by:

commit 4032ec63 upstream. PCI PM suspend callback took down the interface and resume brought it back up. In the mac80211 context this is done in subsequent calls. Rework implementation so that suspend only stores config, and sets PCI power state. The resume return to full power state (D0), restores the config, and brings hardware back up. Full bringup is done by subsequent mac80211 calls. Reviewed-by:

commit 7c161d0b upstream. The hv_netvsc gets RNDIS_STATUS_MEDIA_CONNECT event after the VM is live migrated. Adding call to netif_notify_peers() for this event to send GARP (Gratuitous ARP) to notify network peers. Otherwise, the VM's network connection may stop after a live migration.

commit a786f915 upstream. Removed the call to netif_stop_queue() in netvsc_probe() as the queue is not initialized at that point and further call to it after queue initialization is really not necessary. This change was prompted after an upstream change went into 2.6.37 (netif_tx_stop_queue) that now checks if netif_stop_queue is called before register with netdev is done. This will eliminate the warning message to the log when hv_netvsc driver starts up. Signed-off-by:

commit d1ce3184 upstream. The ni_labpc driver module only requests a shared IRQ for PCI devices, requesting a non-shared IRQ for non-PCI devices. As this module is also used by the ni_labpc_cs module for certain National Instruments PCMCIA cards, it also needs to request a shared IRQ for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus controller.

commit bf3d7d40 upstream. The USB core keeps track of pending resume requests for root hubs, in order to resolve races between wakeup requests and suspends. However the code that does this is subject to another race (between wakeup requests and resumes) because the WAKEUP_PENDING flag is cleared before the resume occurs, leaving a window in which another wakeup request might arrive. This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING flag after the resume instead of before it. This fixes Bugzilla #24952. Signed-off-by:

commit ad84e4a9 upstream. This patch (as1442) fixes a bug in g_printer: Module parameters should not be marked "__initdata" if they are accessible in sysfs (i.e., if the mode value in the module_param() macro is nonzero). Otherwise attempts to access the parameters will cause addressing violations. Character-string module parameters must not be marked "__initdata" if the module can be unloaded, because the kernel needs to access the parameter variable at unload time in order to free the dynamically-allocated string.

commit f75593ce upstream. This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is used to compute the size in a dma_alloc_coherent() call, but then it gets changed later on. As a result, the corresponding call to dma_free_coherent() passes a different size from the original allocation. Fix the problem by adjusting ehci->periodic_size before carrying out any of the memory allocations. Signed-off-by:
