| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently mac80211 determines whether HW does fragmentation by checking whether the set_frag_threshold callback is set or not.

* mac80211: Move reorder-sensitive TX handlers to after TXQ dequeueToke Høiland-Jørgensen2016-09-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The TXQ intermediate queues can cause packet reordering when more than one flow is active to a single station. Since some of the wifi-specific packet handling (notably sequence number and encryption handling) is sensitive to re-ordering, things break if they are applied before the TXQ. This splits up the TX handlers and fast_xmit logic into two parts: An early part and a late part. The former is applied before TXQ enqueue, and the latter after dequeue. The non-TXQ path just applies both parts at once. Because fragments shouldn't be split up or reordered, the fragmentation handler is run after dequeue. Any fragments are then kept in the TXQ and on subsequent dequeues they take precedence over dequeueing from the FQ structure. This approach avoids having to scatter special cases all over the place for when TXQ is enabled, at the cost of making the fast_xmit and TX handler code slightly more complex.

* mac80211: allow driver to handle packet-loss mechanismRajkumar Manoharan2016-09-151-0/+6
| | | | | | | | | | | | | | 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).

* mac80211: RX BA support for sta max_rx_aggregation_subframesMaxim Altshul2016-09-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | 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.

* mac80211: implement codel on fair queuing flowsMichal Kazior2016-06-091-1/+13
| | | | | | | | | | | | | | | | | | | 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.

* mac80211: skip netdev queue control with software queuingMichal Kazior2016-06-091-4/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qdiscs are designed with no regard to 802.11 aggregation requirements and hand out packet-by-packet with no guarantee they are destined to the same tid. This does more bad than good no matter how fairly a given qdisc may behave on an ethernet interface. Software queuing used per-AC netdev subqueue congestion control whenever a global AC limit was hit. This meant in practice a single station or tid queue could starve others rather easily. This could resonate with qdiscs in a bad way or could just end up with poor aggregation performance. Increasing the AC limit would increase induced latency which is also bad. Disabling qdiscs by default and performing taildrop instead of netdev subqueue congestion control on the other hand makes it possible for tid queues to fill up "in the meantime" while preventing stations starving each other. This increases aggregation opportunities and should allow software queuing based drivers achieve better performance by utilizing airtime more efficiently with big aggregates.

* mac80211: allow software PS-Poll/U-APSD with AP_LINK_PSJohannes Berg2016-05-121-0/+27
| | | | | | | | | | | | | | | | When using RSS, frames might not be processed in the correct order, and thus AP_LINK_PS must be used; most likely with firmware keeping track of the powersave state, this is the case in iwlwifi now. In this case, the driver can use ieee80211_sta_ps_transition() to still have mac80211 manage powersave buffering. However, for U-APSD and PS-Poll this isn't sufficient. If the device can't manage that entirely on its own, mac80211's code should be used. To allow this, export two functions: ieee80211_sta_uapsd_trigger() and ieee80211_sta_pspoll().

This avoids the need for copying data of aggregated frames. Running without it is only supported for debugging purposes.

Similarly to CCMP, move the TX IVs of TKIP keys to the public part of the key struct, and export a function to add the IV right into the crypto header. The public tx_pn field is defined as atomic64, so define TKIP_PN_TO_IV16/32 helper macros to convert it to iv16/32 when needed. Since the iv32 used for the p1k cache is taken directly from the frame, we can safely remove iv16/32 from being protected by tkip.txlock.

This means it isn't possible to filter frames within a BA session in firmware. Introduce an API function that allows such filtering. Calling this function will move the BA window forward to the new SSN, and allows marking frames after the SSN as having been filtered, so any future reordering activity will release frames while skipping the holes.

| | | | | | | | | | | | | | | | | | Drivers/devices without their own rate control algorithm can get the information what rates they should use from either the radiotap header of injected frames or from the rate control algorithm. But the parsing of the legacy rate information from the radiotap header was removed in commit e6a9854b05c1 ("mac80211/drivers: rewrite the rate control API"). The removal of this feature heavily reduced the usefulness of frame injection when wanting to simulate specific transmission behavior. Having rate parsing together with MCS rates and retry support allows a fine grained selection of the tx behavior of injected frames for these kind of tests.

To do that allow drivers to tell mac80211 whether a given frame should be: - processed but not delivered to any monitor vif - not processed but delievered to monitor vifs only Signed-off-by: Grzegorz Bajorski <grzegorz.bajorski@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: support hw managing reorder logicSara Sharon2016-02-241-0/+6
| | | | | | | | | | Enable driver to manage the reordering logic itself. This is needed for example for the iwlwifi driver that will support hardware assisted reordering.

* mac80211: pass block ack session timeout to to driverSara Sharon2016-01-141-14/+30
| | | | | | | | | | | | Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure.

* mac80211: document status.freq restrictionsJohannes Berg2016-01-141-0/+2
| | | | | | | | | It's not always necessary to set the status.freq field, for example when this would be an expensive calculation. It must be set for all management frames (as they might be reported to userspace), but for data frames it's not really required. Document this. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: pass RX aggregation window size to driverSara Sharon2016-01-141-3/+5
| | | | | | | | | | | Currently mac80211 does not inform the driver of the window size when starting an RX aggregation session. To enable managing the reorder buffer in the driver or hardware the window size is needed.

* mac80211: add flag for duplication checkSara Sharon2016-01-141-1/+1
| | | | | | | | | | | | Add an option for driver to check for packet duplication by itself. This is needed for example by the iwlwifi driver which parallelizes the RX path and does the duplication check per queue.
