Add a new WoWLAN API to enable net-detect as a wake up trigger. Net-detect allows the device to scan in the background while the host is asleep to wake up the host system when a matching network is found. Reuse the scheduled scan attributes to specify how the scan is performed while suspended and the matches that will trigger a wake event.

For net detect, we will need to reuse most of the scheduled scan parsing function, but not all, so split out the attributes parsing part out of the main start sched_scan function. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

In TDLS (e.g., TDLS off-channel) there is a requirement for some drivers to supply an unused TID between the AP and the device to the FW, to allow sending PTI requests and to allow the FW to aggregate on a specific TID for better throughput. To ensure that the allocated TID is indeed unused, this patch introduces an API for blocking the driver from TXing on that TID.

Implement the cfg80211 TDLS channel switch ops and introduce new mac80211 ones for low-level drivers. Verify low-level driver support for the new ops when using the relevant wiphy feature bit. Also verify the peer supports channel switching before passing the command down. Add a new STA flag to track the off-channel state with the TDLS peer and make sure to cancel the channel-switch if the peer STA is unexpectedly removed.

Introduce commands to initiate and cancel TDLS channel-switching. Once TDLS channel-switching is started, the lower level driver is responsible for continually initiating channel-switch operations and returning to the base (AP) channel to listen for beacons from time to time. Upon cancellation of the channel-switch all communication between the relevant TDLS peers will continue on the base channel.

The AP or peer can prohibit TDLS channel switch via a bit in the extended capabilities IE. Parse the IE and track this bit.

For some TDLS channel switch implementations data frames need to be sent by the firmware based on a template. This template should be created by mac80211, and thus needs to properly be built from an 802.3 frame into an 802.11 frame. In addition, the device will need the key information so the select_key handler needs to be run. However, the driver/device will be responsible for all of the crypto encapsulation, as the sequence numbers etc. cannot be built by the host anyway in this case since it's a template to be used multiple times.

Currently, when a roc period expires, the offchannel timer calls ieee80211_remain_on_channel_expired(), but the roc state is cleared only when the queued work to switch to the operating channel gets a chance to run. This race is a problem because mac80211 can issue a new roc request in this window. To avoid this, handle roc completion in the offchannel timer itself.

In a GO/STA setup, when we switch to the STA context, the channel context timer is scheduled with a period of half the beacon interval. If a beacon is received in this duration, the timer is adjusted to accommodate TSF sync done by the HW. But, if the actual channel switch is delayed for some reason, we end up rearming the timer every time a new beacon is received. Avoid this by doing the adjustment only once.

This patch makes sure that pending roc/scan operations are cancelled properly when a new context is assigned/unassigned. The flush_work() call to flush out any scheduled channel context work is removed, instead, sc->mutex is dropped to allow any pending work to get a chance to complete by the channel scheduler. Also, increase the timeout to allow a switch to an active GO. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

When a pending roc or scan operation is cancelled, the offchannel operation is cleared, but the offchannel state in the main scheduler is not cleared. This causes problems since an active GO will try to process a stale offchannel request that was deferred earlier. Fix this by clearing the state when there is no pending offchannel (roc/scan) operation. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

The base TSF is used for HW timers 0..7, but chips in the AR9003 family and above can support more generic timers. To use them, however, a second HW TSF needs to be enabled. This patch allows usage of the extra timers by starting the second TSF properly. The extra set of HW timers is apparently also present in AR9287, but we enable it only for the AR9003 family.

In secured mesh, the unicast mgmt frame is encrypted using the same key that used for encrypting the unicast data frame. This patch "ath9k_htc_firmware: fix the offset of CCMP header for mesh data frame" applied to open-ath9k-htc-firmware allows the ath9k_htc to be loaded without "nohwcrypt=1". Unfortunately, this is not working and we still need CCMP encryption of transmitted management frames to be done in software. So this patch allows the software encryption for transmitted management frame to be done in software but remain the hardware decryption for received management frame. This patch is tested with the following hardwares: - TP-Link TL-WN821N v3 802.11n [Atheros AR7010+AR9287] - AR9271 802.11n and managed to work with peer mesh STA equipped with ath9k.

This patch adds auto TDLS support to mwifiex. Auto TDLS functionality works as follows: 1. Whenever userspace application has triggered TDLS connection with any peer, driver would store this peer mac address details in its database. 2. After this driver whenever driver receives packet on direct link, it would store rssi and timestamp in peer information. 3. Whenever a packet is to be transmitted to non-AP peer in station mode, driver would check if TDLS link can be established by looking at peer RSSI information. Driver would initiate TDLS setup in such cases. 4. Periodic timer is used for updating peer information. 5. Auto TDLS peer list & timer are cleared during disconnection or driver unload.
