In 46fa38e8 ("mac80211: allow software PS-Poll/U-APSD with AP_LINK_PS"), Johannes allowed to use mac80211's code for handling stations that go to PS or send PS-Poll / uAPSD trigger frames for devices that enable RSS. This means that mac80211 doesn't look at frames anymore but rather relies on a notification that will come from the device when a PS transition occurs or when a PS-Poll / trigger frame is detected by the device. iwlwifi will need this capability but still needs mac80211 to take care of the TIM IE. Today, if a driver sets AP_LINK_PS, mac80211 will not update the TIM IE. Change mac80211 to check existence of the set_tim driver callback rather than using AP_LINK_PS to decide if the driver handles the TIM IE internally or not.

Based on consecutive msdu failures, mac80211 triggers CQM packet-loss mechanism. Drivers like ath10k that have its own connection monitoring algorithm, offloaded to firmware for triggering station kickout. In case of station kickout, driver will report low ack status by mac80211 API (ieee80211_report_low_ack). This flag will enable the driver to completely rely on firmware events for station kickout and bypass mac80211 packet loss mechanism.

smatch pointed out that the second check of "tdls_auth" was pointless since if it was true, we returned from the function already.

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).

由 Maxim Altshul 提交于
The ability to change the max_rx_aggregation frames is useful in cases of IOP. There exist some devices (latest mobile phones and some AP's) that tend to not respect a BA sessions maximum size (in Kbps). These devices won't respect the AMPDU size that was negotiated during association (even though they do respect the maximal number of packets). This violation is characterized by a valid number of packets in a single AMPDU. Even so, the total size will exceed the size negotiated during association. Eventually, this will cause some undefined behavior, which in turn causes the hw to drop packets, causing the throughput to plummet. This patch will make the subframe limitation to be held by each station, instead of being held only by hw.

Beacon report radio measurement requires reporting observed BSSs on the channels specified in the beacon request. If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO).

The current implementation of handling ADDBA Request while a session is already active with the peer is wrong - in case the peer is using the existing session's dialog token this should be treated as update to the session, which can update the timeout value.

We've accumulated a couple of different fixes now to mesh_sta_cleanup() due to the different paths that user_mpm and !user_mpm cases take -- one fix to flush nexthop paths and one to fix the counting. The only caller of mesh_plink_deactivate() is mesh_sta_cleanup(), so we can push the user_mpm checks down into there in order to share more code. In doing so, we can remove an extra call to mesh_path_flush_by_nexthop() and the (unnecessary) call to mesh_accept_plinks_update(). This will also ensure the powersaving state code gets called in the user_mpm case. The only cleanup tasks we need to avoid when MPM is in user-space are sending the peering frames and stopping the plink timer, so wrap those in the appropriate check.

If a user space program (e.g., wpa_supplicant) deletes a STA entry that is currently in NL80211_PLINK_ESTAB state, the number of established plinks counter was not decremented and this could result in rejecting new plink establishment before really hitting the real maximum plink limit. For !user_mpm case, this decrementation is handled by mesh_plink_deactive(). Fix this by decrementing estab_plinks on STA deletion (mesh_sta_cleanup() gets called from there) so that the counter has a correct value and the Beacon frame advertisement in Mesh Configuration element shows the proper value for capability to accept additional peers.

There is no other limit other than a global packet count limit when using software queuing. This means a single flow queue can grow insanely long. This is particularly bad for TCP congestion algorithms which requires a little more sophisticated frame dropping scheme than a mere headdrop on limit overflow. Hence apply (a slighly modified, to fit the knobs) CoDel5 on flow queues. This improves TCP convergence and stability when combined with wireless driver which keeps its own tx queue/fifo at a minimum fill level for given link conditions.
