2014-04-09ath9k: fix a scheduling while atomic bug in CSA handlingFelix Fietkau1-4/+3
Commit "ath9k: prepare for multi-interface CSA support" added a call to ieee80211_iterate_active_interfaces in atomic context (beacon tasklet), which is crashing. Use ieee80211_iterate_active_interfaces_atomic instead. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-04-09ath9k_hw: reduce ANI firstep range for older chipsFelix Fietkau1-3/+1

2014-04-08ath10k: refactor monitor codeMichal Kazior3-98/+135
It was possible to create/delete/start/stop monitor vdev from a few places that were not exclusively protected against each other. This resulted in monitor vdev being stopped/removed by one call origin while another one was expecting it to continue running. For example if CAC was started and interface's promiscuous mode was toggled monitor vdev was removed from the driver meaning no radar would be detected. In additional a warning would be printed upon CAC completion complaining it tried to stop non-running monitor vdev. The patch simplifies monitor code by removing IEEE80211_HW_WANT_MONITOR_VIF (which wasn't really ever needed) and improves state tracking. It also unifies prints.

The filed has been missing (missmatched with FW ABI) since 999.999.0.629 firmware release. It's very imporatant to keep these structs up to date with FW, due to the arithmetic we use while read the fw_stats.

2014-03-28ath10k: deinit copy engine before resettingMichal Kazior1-1/+1
Since copy engine allocation has been revised the ath10k_pci_ce_deinit() now simply zeroes copy engine registers. It's probably a good idea to do that before reseting for a more graceful device reset. Before ath10k_pci_ce_deinit() freed copy engine ringbuffer memory so it was required to call it after resetting. Otherwise it was possible for device to access unmapped/freed copy engine ringbuffer memory. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-03-28ath10k: split ce initialization and allocationMichal Kazior3-158/+228
Definitions by which copy engine structure are allocated do not change so it doesn't make much sense to re-create those structures each time device is booted (e.g. due to firmware recovery). This should decrease chance of memory allocation failures. While at it remove per_transfer_context pointer indirection. The array has been trailing the copy engine ringbuffer structure anyway. This also saves pointer size worth of bytes for each copy engine ringbuffer.

2014-03-25ath10k: fix rssi and rate reportingJanusz Dziedzic1-4/+5
RSSI and RATES fields are valid only when START_VALID bit is set. So, in current implementation we have to remember/caclulate them when START_VALID and report the same when only END_VALID is set. Currently during heavy traffic we could have: - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID ... Next using monitor interface we will see: - 10 packets with correct rssi/rates - 10 packets with rssi=-95/rate=6Mbps Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-24ath10k: add soft/hard firmware crash option to simulate_fw_crashMarek Puzyniak1-14/+40
Command WMI_FORCE_FW_HANG_CMDID is not supported in firmware 10.1. In order to have firmware crash simulation functionality also in firmware 10.1 driver can force firmware crash by performing not allowed operation. Driver can deliberately crash firmware when setting vdev param for vdev id out of range. This patch introduces two keywords to simulate_fw_crash: 'soft' which will cause firmware crash that is recoverable by warm firmware reset but supported only in main firmware. 'hard' which will cause firmware crash recoverable by cold firmware reset, this option works for both firmwares. Commands to trigger firmware soft/hard crash: echo 'soft' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash echo 'hard' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash kvalo: remove '\n' before checking the command and simplify how buf is null terminated Signed-off-by: Marek Puzyniak <marek.puzyniak@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-03-17wil6210: fix race between disconnect and Tx NAPIVladimir Kondratiev6-4/+47
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.
