* mac80211: add back lost debugfs filesJohannes Berg2017-02-071-0/+1
| | | | | | | Somehow these files were never present or lost, but the code is there and they seem somewhat useful, so add them back. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: improve RX aggregation data in debugfsJohannes Berg2016-10-191-2/+7
| | | | | | | | | | When the driver sets the SUPPORTS_REORDERING_BUFFER hardware flag, the debugfs data for RX aggregation sessions won't even indicate that a session is open. Since the previous fix to store the dialog token separately, we can indicate that it's open and add the token so that there's at least some data (ssn is not available.)

* mac80211: fix tid_agg_rx NULL dereferenceJohannes Berg2016-10-191-1/+1
| | | | | | | | | | | | | | | On drivers setting the SUPPORTS_REORDERING_BUFFER hardware flag, we crash when the peer sends an AddBA request while we already have a session open on the seame TID; this is because on those drivers, the tid_agg_rx is left NULL even though the session is valid, and the agg_session_valid bit is set. To fix this, store the dialog tokens outside the tid_agg_rx to be able to compare them to the received AddBA request.

* mac80211: remove sta_remove_debugfs driver callbackJohannes Berg2016-09-151-4/+0

* mac80211: Re-structure aqm debugfs output and keep CoDel stats per txqToke Høiland-Jørgensen2016-09-131-0/+52
| | | | | | | | | | | | | | | Currently the 'aqm' stats in mac80211 only keeps overlimit drop stats, not CoDel stats. This moves the CoDel stats into the txqi structure to keep them per txq in order to show them in debugfs. In addition, the aqm debugfs output is restructured by splitting it up into three files: One global per phy, one per netdev and one per station, in the appropriate directories. The files are all called aqm, and are only created if the driver supports the wake_tx_queue op (rather than emitting an error on open as previously).

* mac80211: move station statistics into sub-structsJohannes Berg2015-10-211-3/+3
| | | | | | | | | | | | | | Group station statistics by where they're (mostly) updated (TX, RX and TX-status) and group them into sub-structs of the struct sta_info. Also rename the variables since the grouping now makes it obvious where they belong.

| | | | | | | | | | | | | Remove items that can be retrieved through nl80211. This also removes two items (tx_packets and tx_bytes) where only the VO counter was exposed since they are split up per AC but in the debugfs file only the first AC was shown.

* mac80211: remove TX latency measurement codeJohannes Berg2015-02-281-134/+0
| | | | | | | | | | | | | | | | Revert commit ad38bfc916da ("mac80211: Tx frame latency statistics") (along with some follow-up fixes). This code turned out not to be as useful in the current form as we thought, and we've internally hacked it up more, but that's not very suitable for upstream (for now), and we might just do that with tracing instead. Therefore, for now at least, remove this code. We might also need to use the skb->tstamp field for the TCP performance issue, which is more important than the debugging.

When a peer link is established, use the default power mode stored in mesh config. Update the PS status if the peering status of a neighbor changes. Maintain a mesh power mode for non-peer mesh STAs. Set the non-peer power mode to active mode during peering. Authenticated mesh peering is currently not working when either node is configured to be in power save mode. Indicate the current power mode in transmitted frames. Use QoS Nulls to indicate mesh power mode transitions. For performance reasons, calls to the function setting the frame flags are placed in HWMP routing routines, as there the STA pointer is already available. Add peer_pm to sta_info to represent the peer's link-specific power mode towards the local station. Add nonpeer_pm to represent the peer's power mode towards all non-peer stations. Track power modes based on received frames. Add the ps_data structure to ieee80211_if_mesh (for TIM map, PS neighbor counter and group-addressed frame buffer). Set WLAN_STA_PS flag for STA in PS mode to use the unicast frame buffering routines in the tx path. Update num_sta_ps to buffer and release group-addressed frames after DTIM beacons. Announce the awake window duration in beacons if in light or deep sleep mode towards any peer or non-peer. Create a TIM IE similarly to AP mode and add it to mesh beacons. Parse received Awake Window IEs and check TIM IEs for buffered frames. Release frames towards peers in mesh Peer Service Periods. Use the corresponding trigger frames and monitor the MPSP status. Append a QoS Null as trigger frame if neccessary to properly end the MPSP. Currently, in HT channels MPSPs behave imperfectly and show large delay spikes and frame losses.

* | mac80211: Implement mesh synchronization frameworkJavier Cardona2012-04-101-2/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds MBSS extensible synchronization framework (Sec. 13.13.2 of IEEE Std. 802.11-2012). The framework is implemented via an ops table which defines the following functions: rx_bcn_presp() - this is called every time a mesh beacon is received. adjust_tbtt() - this is called immediately before a beacon is about to be transmitted. The default neighbor offset synchronization defined in the standard is implemented. We also provide template functions for vendor specific methods. When neighbor offset synchronization is active (which is the default) mesh neighbors in the same MBSS will track timing offsets to each other and compensate clock drift. In our tests we observed that this mesh synchronization implementation successfully corrected drifts between stations of ~2PPM while introducing a jitter of ~20us. It is also possible to test this framework on mac80211_hwsim simulated phys to see how it behaves under different topologies, over poor links, etc. Signed-off-by: Marco Porsch <marco.porsch@s2005.tu-chemnitz.de> Signed-off-by: Pavel Zubarev <pavel.zubarev@gmail.com> Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W.
