ath9k: fix aggregation session lockup

2014-07-23T17:03:11Z

If an aggregation session fails, frames still end up in the driver queue with IEEE80211_TX_CTL_AMPDU set. This causes tx for the affected station/tid to stall, since ath_tx_get_tid_subframe returning packets to send. Fix this by clearing IEEE80211_TX_CTL_AMPDU as long as no aggregation session is running. Cc: stable@vger.kernel.org Reported-by: Antonio Quartulli Signed-off-by: Felix Fietkau Signed-off-by: John W.

iwlwifi: mvm: pass beacons from foreign APs

2014-07-21T07:38:25Z

In AP mode, configure the fw to pass beacons from foreign APs, in order to be able to set the ht protection IE properly. Add the same filters in case of GO (which didn't have any configured filter_flags, probably by mistake) Signed-off-by: Eliad Peller Signed-off-by: Emmanuel Grumbach

rt2800usb: Don't perform DMA from stack

2014-07-07T19:04:34Z

Function rt2800usb_autorun_detect() passes the address of a variable allocated onto the stack to be used for DMA by the USB layer. This has been caught by my debugging-enabled kernel. This patch change things in order to allocate that variable via kmalloc, and it adjusts things to handle the kmalloc failure case, propagating the error.

mwifiex: initialize Tx/Rx info of a packet correctly

iwlwifi: mvm: disable CTS to Self

2014-07-03T17:55:18Z

Firmware folks seem say that this flag can make trouble. Drop it. The advantage of CTS to self is that it slightly reduces the cost of the protection, but make the protection less reliable. Cc: [3.13+] Signed-off-by: Emmanuel Grumbach

iwlwifi: dvm: don't enable CTS to self

2014-07-03T11:59:38Z

We should always prefer to use full RTS protection. Using CTS to self gives a meaningless improvement, but this flow is much harder for the firmware which is likely to have issues with it. CC: Signed-off-by: Emmanuel Grumbach
