2014-07-15wlcore/wl18xx/wl12xx: convert bitmaps to unsigned longsEliad Peller6-17/+17
The *_bit operations expect unsigned longs. Instead of casting the pointers, simply define various bitmaps as unsigned long (instead of u32). Signed-off-by: Eliad Peller <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2014-07-15wl18xx: make sure fw_status->priv exists before derefEliad Peller1-2/+12
In some corner cases with specific timings, we might try dequeueing tx before we got information about the link status (e.g. due to recovery during tx). Instead of NULL dereference, assume all the links in this case have low priorities. Signed-off-by: Eliad Peller <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2014-07-15wl18xx: change the number of WLAN addrs per chipArik Nemtsov1-1/+1

2014-07-15wlcore: user smaller sqn padding for GEMEliad Peller3-4/+13
On recovery, we increase the current seq num by WL1271_TX_SQN_POST_RECOVERY_PADDING in order to compensate for packets we might have missed during recovery. It seems that some GEM APs have issues when the gap is too big, so use a smaller padding in this case. Signed-off-by: Eliad Peller <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2014-07-15wlcore: save seq num only between recoveriesEliad Peller3-31/+68
We want seq num (freed_pkts) to be initialized on each new connection, but keep persistent between recoveries/suspends. Save the freed_pkts in the private block of the sta struct (we already do a similar thing for AP's stations). However, keep the old wlvif->total_freed_pkts in order to avoid too intrusive change.

2014-07-15ath10k: sanitize tx ring index access properlyMichal Kazior1-4/+7
The tx ring index was immediately trimmed with a bitmask. This discarded the 0xFFFFFFFF error case (which theoretically can happen when a device is abruptly disconnected) and led to using an invalid tx ring index. This could lead to memory corruption.

2014-07-15ath10k: fix bmi exchange tx/rx raceMichal Kazior2-9/+5
It was possible for tx completion not to be processed. In that case an old stack pointer was left on copy engine tx ring. Next bmi exchange would immediately pop it and use complete() on the completion struct there causing corruption. Make sure to wait for both tx and rx completions properly.

2014-07-14ath10k: fix unregister deadlock when fw probe failsMichal Kazior1-1/+3
If firmware probing worker failed it called device_release_driver() which synchronously called remove() pci callback. The callback in turn waited for the worker that called it to finish resulting in a deadlock. Waiting for a completion instead of a worker, like some other drivers do, doesn't seem like the best idea either: Syscall Worker probe_fw() rmmod dev_lock() pci->remove() wait_for_completion() complete_all() device_release_driver() dev_lock() [sleep] free(ar) dev_unlock() [resume] There's no guarantee that Worker upon resuming can still access any data/code of the module. Leaving device bound to a driver is not as harmful as deadlocking so remove the call to device_release_driver() while a proper solution is figured out.

2014-07-14ath6kl: convert ar6004 hardware flags to firmware feature flagsKalle Valo6-17/+42
The functionality defined through these flags were actually firmware features which can change between firmware versions. To make it possible to support different firmware versions with the same driver, convert the flags to firmware feature flags. For backwards compatibility support for old ar6004 firmware FW API 3 or smaller images we forcefully set the feature bits in the driver. Starting from FW API 5 the firmware image needs to set them.
