* ath9k: backport dynack improvementsKoen Vandeputte2019-08-284-0/+300
| | | | | | | | | | | | | | | | | | | | | | | | | | | Close cooperation with Lorenzo Bianconi resulted in these patches which fix all remaining seen issues when using dynack. Fix link losses when: - Late Ack's are not seen or not present - switching from too low static coverage class to dynack on a live link These are fixed by setting the Ack Timeout/Slottime to the max possible value for the currently used channel width when a new station has been discovered. When traffic flows, dynack is able to adjust to optimal values within a few packets received (typically < 1 second) These changes have been thoroughly tested on ~60 offshore devices all interconnected using mesh over IBSS and dynack enabled on all. Distances between devices varied from <100m up to ~35km [move patches to correct folder + renumber] Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> (cherry picked from commit f6e8ba0238fe349b7529357793e2fb18635819ed)

* ath9k: register GPIO chip for OF targetsMathias Kresin2019-02-102-10/+19
| | | | | | | | | | | | | | | | | | | | This partitialy reverts commit f506de2cdaf9. Registering the GPIO chip without a parent device completely breaks the ath9k GPIOs for device tree targets. As long as boards using the devicetree don't have the gpio-controller property set for the ath9k node, the unloading of the driver works as expected. Register the GPIO chip with the ath9k device as parent only for OF targets to find a trade-off between the needs of driver developers and the broken LEDs and buttons seen by users.

* mac80211: brcmfmac: backport firmware loading changes & fix memory bugsRafał Miłecki2019-01-088-15/+620
| | | | | | | | | | | | | | | | This pick most of brcmfmac changes backported into the master in commits 5932eb690f24 ("mac80211: brcmfmac: backport firmware loading cleanup") 3eab6b8275b2 ("mac80211: brcmfmac: backport NVRAM loading improvements") 529c95cc15dc ("mac80211: brcmfmac: fix use-after-free & possible NULL pointer dereference") It's more than would be normally backported into a stable branch but it seems required. Firmware loading cleanups are needed to allow fix memory bugs in a reliable way. Memory fixes are really important to avoid corrupting memory and risking a NULL pointer dereference. Hopefully this stuff has received enough testing in the master. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* 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: 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.
