2014-03-17wil6210: fix race between disconnect and Tx NAPIVladimir Kondratiev
When disconnecting some CID, corresponded Tx vring get released. During vring release, all descriptors get freed. It is possible that Tx NAPI working on the same vring simultaneously. If it happens, descriptor may be double freed. To protect from the race above, make sure NAPI won't process the same vring. Introduce 'enabled' flag in the struct vring_tx_data. Proceed with Tx NAPI only if 'enabled' flag set. Prior to Tx vring release, clear this flag and make sure NAPI get synchronized. NAPI enablement status protected by wil->mutex, add protection where it was missing and check for it. During reset, disconnect all peers first, then proceed with the Rx vring. It allows for the disconnect flow to observe proper 'wil->status' and correctly notify cfg80211 about connection status change Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

2014-03-17wil6210: Fix kernel oops in reset flowVladimir Kondratiev
wil_reset() removes vring's At the same time NAPI may be active performing Rx/Tx completion. If this happens, Rx/Tx polling functions going to access already removed vrings Make sure NAPI is idle and won't be started prior to vring removal. For this, track NAPI enabled state Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-03-17wil6210: fix memory leak in the AP flowVladimir Kondratiev
When switching between STA and AP modes, memory allocated for Rx vring leaks This is because start_ap() allocates Rx vring but stop_ap() do not free it. Logically, Rx vring is not valid (HW can't use it anymore), so free it in reset() Also, check double init for Rx vring and bail out with -EINVAL Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

2014-03-14ath9k_hw: set ANI firstep as absolute values instead of relativeFelix Fietkau
On older chips, the INI value differ in similar ways as cycpwr_thr1, so convert it to absolute values as well. Since the ANI algorithm is different here compared to the old implementation (fewer steps, controlled at a different point in time), it makes sense to use values similar to what would be applied for newer chips, just without relying on INI defaults.
