* ath9k: fix dynack in IBSS modeKoen Vandeputte2018-11-065-0/+309
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, dynack was only tested upstream using AP/STA mode. Testing it on IBSS, showed that late-ack detection was broken. This is caused due to dynack using Association Request/Response frames for late-ack detection, which IBSS does not use. Also allowing Authentication frames here solves this. A second issue also got fixed, which was also seen AP/STA mode: When a station was added, the estimated value would be exponentially averaged using 0 as a starting point. This means that on larger distances, the ack timeout was still not high enough before synchronizing would run out of late-ack's for estimation. Fix this by using the initial estimated value as a baseline and only start averaging in the following estimation rounds. Test setup: - 2x identical devices: RB912UAG-5HPnD + 19dB sector - IBSS - 2x2 802.11an (ar9340), HT20, long GI - RSSI's -70 / -71 - Real distance: 23910 meter Results (60s iperf runs): Fixed coverage class 54 (up to 24300m): * 21.5 Mbits/sec Dynack: * 28.9 Mbits/sec Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>

* mac80211: Expose support for ath9k DynackKoen Vandeputte2018-07-121-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enables support for Dynack feature. When a remote station is far away, we need to compensate for the distance by allowing more time for an ACK to arrive back before issueing a retransmission. Currently, it needs to be set fixed to indicate the maximum distance the remote station will ever be. While this mostly works for static antennae, it introduces 2 issues: - If the actual distance is less, speed is reduced due to a lot of wates wait-time - If the distance becomes greater, retries start to occur and comms can get lost. Allowing to set it dynamically using dynack ensures the best possible tradeoff between speed vs distance. This feature is currently only supported in ath9k. it is also disabled by default. Enabling it can be done in 2 ways: - issue cmd: iw phy0 set distance auto - sending the NL80211_ATTR_WIPHY_DYN_ACK flag to mac80211 driver using netlink Disabling it can be done by providing a valid fixed value. To give an idea of a practical example: In my usecase, we have mesh wifi device installed on ships/platforms. Currently, the coverage class is set at 12000m fixed. When a vessel moved closer (ex. 1500m), the measured link capacity was a lot lower compared to setting the coverage class fixed to 1500m Dynack completely solved this, nearly providing double the bandwidth at closer range compared to the fixed setting of 12000m being used. Also when a vessel sailed to a distance greater than the fixed setting, communication was lost as the ACK's never arrived within the max allowed timeframe. Actual distance: 6010m iperf 60s run avg Fixed 12150m: 31 Mbit/s Dynack: 58 Mbit/s Fixed 6300m: 51 Mbit/s Dynack: 59 Mbit/s Fixed 3000m: 13 Mbit/s (lots of retries) Dynack: 58 Mbit/s Actual distance: 1504m iperf 60s run avg Fixed 12150m: 31 Mbit/s Dynack: 86 Mbit/s Fixed 6300m: 55 Mbit/s Dynack: 87 Mbit/s Fixed 3000m: 67 Mbit/s Dynack: 87 Mbit/s Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
* mac80211: initialize sinfo in cfg80211_get_stationSven Eckelmann2018-07-081-0/+42
| | | | | | | | | | | | | | | | | | | | Most of the implementations behind cfg80211_get_station will not initialize sinfo to zero before manipulating it. For example, the member "filled", which indicates the filled in parts of this struct, is often only modified by enabling certain bits in the bitfield while keeping the remaining bits in their original state. A caller without a preinitialized sinfo.filled can then no longer decide which parts of sinfo were filled in by cfg80211_get_station (or actually the underlying implementations). cfg80211_get_station must therefore take care that sinfo is initialized to zero. Otherwise, the caller may tries to read information which was not filled in and which must therefore also be considered uninitialized. In batadv_v_elp_get_throughput's case, an invalid "random" expected throughput may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may switch to non-optimal neighbors for certain destinations.
