iwlwifi: mvm: support ibss in dqa mode

2017-03-24T15:15:25Z

Allow working IBSS also when working in DQA mode. This is done by setting it to treat the queues the same as a BSS AP treats the queues. Fixes: 7948b87308a4 ("iwlwifi: mvm: enable dynamic queue allocation mode") Signed-off-by: Liad Kaufman Signed-off-by: Luca Coelho

iwlwifi: mvm: writing zero bytes to debugfs causes a crash

2017-03-24T15:15:25Z

This is a static analysis fix. The warning is: drivers/net/wireless/intel/iwlwifi/mvm/fw-dbg.c:912 iwl_mvm_fw_dbg_collect() warn: integer overflows 'sizeof(*desc) + len' I guess this code is supposed to take a NUL character, but if we write zero bytes then it tries to write -1 characters and crashes.

iwlwifi: mvm: fix accessing fw_id_to_mac_id

iwlwifi: mvm: cleanup pending frames in DQA mode

2017-03-16T07:53:39Z

When a station is asleep, the fw will set it as "asleep". All queues that are used only by one station will be stopped by the fw. In pre-DQA mode this was relevant for aggregation queues. However, in DQA mode a queue is owned by one station only, so all queues will be stopped. As a result, we don't expect to get filtered frames back to mac80211 and don't have to maintain the entire pending_frames state logic, the same way as we do in aggregations. The correct behavior is to align DQA behavior with the aggregation queue behaviour pre-DQA: - Don't count pending frames. - Let mac80211 know we have frames in these queues so that it can properly handle trigger frames. When a trigger frame is received, mac80211 tells the driver to send frames from the queues using release_buffered_frames. The driver will tell the fw to let frames out even if the station is asleep. This is done by iwl_mvm_sta_modify_sleep_tx_count. Reported-and-tested-by: Jens Axboe Reported-by: Linus Torvalds Signed-off-by: Sara Sharon Signed-off-by: Luca Coelho Signed-off-by: Kalle Valo

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47Z

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
