2013-08-05ath9k: Add a HW capability for WLAN/BT RX diversitySujith Manoharan4-9/+28

2013-08-05ath9k: Cleanup WLAN/BT RX diversitySujith Manoharan4-28/+26
For single-chain WLAN+BT cards, the BT antenna can be used for WLAN RX when the BT interface is disabled. Rename the modparam "antenna_diversity" to "bt_ant_diversity" to clarify this. Signed-off-by: Sujith Manoharan <[email protected]> Signed-off-by: John W. Linville <[email protected]>

2013-08-05cw1200: Fix spurious BUG_ON() trigger when starting AP mode.Solomon Peachy1-5/+2
There's an underlying race condition with the unjoin_work() call that is sometimes triggered depending on scheduling order and the phase of the moon. This doesn't fix the race condition, but it does remove the ill-advised BUG_ON() call in an easily-recoverable situation. Signed-off-by: Solomon Peachy <[email protected]> Signed-off-by: John W.

2013-08-05ath10k: fix device teardownMichal Kazior1-11/+30
This fixes interrupt-related issue when no interfaces were running thus the device was considered powered down. The power_down() function isn't really powering down the device. It simply assumed it won't interrupt. This wasn't true in some cases and could lead to paging failures upon FW indication interrupt (i.e. FW crash) because some structures aren't allocated in that device state. One reason for that was that ar_pci->started wasn't reset. The other is interrupts should've been masked when teardown starts. The patch reorganized interrupt setup and makes sure ar_pci->started is reset accordingly.

2013-08-02iwl4965: reset firmware after rfkill offStanislaw Gruszka2-5/+6
Using rfkill switch can make firmware unstable, what cause various Microcode errors and kernel warnings. Reseting firmware just after rfkill off (radio on) helped with that.

2013-08-02ath10k: zero arvif memory on add_interface()Michal Kazior1-0/+2
The private memory area in vif provided by mac80211 isn't guaranteed to be zeroed. This patch should fix issues when switching between STA and AP interface types. The tim_bitmap could become polluted by STA bssid field (since it's a union), wep_keys array could also become polluted with invalid pointers and probably much more.

2013-08-02ath10k: prevent using invalid ringbuffer indexesMichal Kazior1-0/+5
If the device is removed and hotplug fails ioread32() will return 0xFFFFFFFF. In that case reading ringbuffer during device bringup led to out-of-bounds addressing of a ringbuffer array that in turn led to a paging failure. This could be reproduced by the following: * boot without acpi/prevent hotplug from working * insert and manually detect (pci rescan) the device * remove the device physically * load ath10k driver * kernel crashed Ringbuffer index reading is now protected by using an appropriate mask to prevent addressing an invalid array index.

4965 version of Eric patch "iwl3945: better skb management in rx path". It fixes several problems : 1) skb->truesize is underestimated. We really consume PAGE_SIZE bytes for a fragment, not the frame length. 2) 128 bytes of initial headroom is a bit low and forces reallocations. 3) We can avoid consuming a full page for small enough frames.

If fw_restart is disabled, using the fw_restart debugfs file will enable fw_restart and then send the failing command, but this still frequently fails restart because it resets fw_restart afterwards and is thus racy.
