2014-12-01ath10k: add sanity checks for service bmap parsingMichal Kazior
This shouldn't really happen but take into account the original service bitmap length when mapping service ids. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-12-01ath10k: fix wmi svc bitmap dbg printMichal Kazior
The dump print uses sizeof() but since service_map was a mere pointer the dump was too short. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-11-26ath10k: fix station count enforcementMichal Kazior
The number of peers isn't directly translatable to the number of stations because ath10k needs to reserve a few extra peers for special cases like multi-vif concurrency. The previous limit was 126 and 15 stations in AP mode for 10.x and main firmware branches respectively. The limit is now 128 and 16 which was the original intention.

2014-11-26ath10k: fix shared WEPSujith Manoharan
When static keys are used in shared WEP, when a station is associated, message 3 is sent with an encrypted payload. But, for subsequent authentications that are triggered without a deauth, the auth frame is decrypted by the HW. To handle this, check if the WEP keys have already been set for the peer and if so, mark the frame as decrypted. This scenario can happen when a station changes its default TX key and initiates a new authentication sequence.

2014-11-26ath10k: don't drop corrupted mgmt framesMichal Kazior
Some firmware revisions don't seem to deilver management frames with FCS error via WMI so narrow down the HTT rule to not drop corrupted management frames.

2014-11-17ath10k: fix mismatched wmi api callPeter Oh

2014-11-17ath10k: handle ieee80211 header and payload tracing separatelyRajkumar Manoharan
For packet log, the transmitted frame 802.11 header alone is sufficient. Recording entire packet is also consuming lot of disk space. To optimize this, tx and rx data tracepoints are splitted into header and payload tracepoints. To record tx ieee80211 headers trace-cmd record -e ath10k_tx_hdr To record complete packets trace-cmd record -e ath10k_tx_hdr -e ath10k_tx_payload Cc: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2014-10-31ath10k: speed up hw recoveryMichal Kazior
In some cases hw recovery was taking an absurdly long time due to ath10k waiting for things that would never really complete. Instead of waiting for inevitable timeouts poke all completions and wakequeues and check if it's still worth waiting. Reading/writing ar->state requires conf_mutex. Since waiters might be holding it introduce a new flag CRASH_FLUSH so it's possible to tell waiters to abort whatever they were waiting for.

2014-09-29ath10k: fix fw stats processingMichal Kazior
If stat data exceeds wmi-htc buffer limits firmware splits it into many wmi stats update events which are delivered in a ping-pong fashion triggered by wmi stats request command. Since there's only an implicit start-of-data and no end-of-data indications the driver has to perform some trickery to get complete stat data. kvalo: use %zu to fix a compiler warning and fix a typo in a comment Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-09-23ath10k: deduplicate wmi service ready logicMichal Kazior
The logic responsible for processing the event is no different across different firmware binaries. The difference that needs to be dealt with is the ABI of data structures. The intermediate structure uses __le32 to avoid extra memory allocations to byteswap variable-length substructures (i.e. host mem chunks).

2014-09-23ath10k: workaround fw beaconing bugMichal Kazior
Some firmware revisions don't wait for beacon tx completion before sending another SWBA event. This could lead to hardware using old (freed) beacon data in some cases, e.g. tx credit starvation combined with missed TBTT. This is very very rare. On non-IOMMU-enabled hosts this could be a possible security issue because hw could beacon some random data on the air. On IOMMU-enabled hosts DMAR faults would occur in most cases and target device would crash. Since there are no beacon tx completions (implicit nor explicit) propagated to host the only workaround for this is to allocate a DMA-coherent buffer for a lifetime of a vif and use it for all beacon tx commands. Worst case for this approach is some beacons may become corrupted, e.g. garbled IEs or out-of-date TIM bitmap. Keep the original beacon-related code as-is in case future firmware revisions solve this problem so that the old path can be easily re-enabled with a fw_feature flag.

2014-09-10ath10k: use proper service bitmap sizeMichal Kazior

2014-08-25ath10k: fix a conflict bug in wmi service bitmapMichal Kazior
Service mapping for main firmware branch was incorrectly used for 10.x firmware and vice-versa. This caused wmi_services in debugfs to print wrong values.

2014-08-12ath10k: introduce a stricter scan state machineMichal Kazior
This aims at fixing some rare scan bugs related to firmware reporting unexpected scan event sequences. One such bug was if spectral scan phyerr reporting prevented firmware from properly propagating scan events to host. This led to scan timeout. After that next scan would trigger scan completed event first (before scan started event) leading to ar->scan.in_progress and timeout timer states to be overwritten incorrectly and making the very next scan to hang forever.

2014-08-04ath10k: add spectral scan featureSimon Wunderlich
Adds the spectral scan feature for ath10k. The spectral scan is triggered by configuring a mode through a debugfs control file. Samples can be gathered via another relay debugfs file.

2014-07-28ath10k: add support for 10.2 firmwareMichal Kazior
The 10.2 firmware is a successor of 10.1 firmware (formerly identified as 10.x). Both share a lot but have some slight ABI differences that need to be taken care of.
