* mac80211: brcmfmac: backport wowlan netdetect fixesRafał Miłecki2017-02-064-2/+149
| | | | | | | | | | | | | | I needed a moment to figure out relation between this patchset and the nl80211: fix validation of scheduled scan info for wowlan netdetect It appears nl80211 commit will go on top of brcmfmac changes so it's safe to backport these patches. One patch that was excluded is commit 2a2a5d1835b6 ("brcmfmac: add .update_connect_params() callback") as it depends on missing commit 088e8df82f91 ("cfg80211: Add support to update connection parameters").

This issue was easiest to trigger on AR913x devices, e.g. the TP-Link TL-WR1043ND, but other hardware was occasionally affected as well.

* mac80211: backport "cfg80211: limit scan results cache size"Christian Lamparter2016-12-191-0/+150
| | | | | | | | | | | | | | | | | | | | | | | The patch commit states: "It's possible to make scanning consume almost arbitrary amounts of memory, e.g. by sending beacon frames with random BSSIDs at high rates while somebody is scanning. Limit the number of BSS table entries we're willing to cache to 1000, limiting maximum memory usage to maybe 4-5MB, but lower in practice - that would be the case for having both full-sized beacon and probe response frames for each entry; this seems not possible in practice, so a limit of 1000 entries will likely be closer to 0.5 MB." Signed-off-by: Johannes Berg <johannes.berg@intel.com>" This patch was added in 4.4.36. But because LEDE backports cfg80211, mac80211 and the wifi drivers separately, it needs to be added manually for now. It can be dropped later as it will be part of the next mac80211 refresh.

* kernel: mac80211: disable ath9k bands via device treeMartin Blumenstingl2016-11-291-0/+32
| | | | | | | | | | | | | These properties allow overriding the settings from the EEPROM which indicate whether a band is enabled or not. Setting this property is only needed when the RF circuit does not support the 2.4GHz or 5GHz band while it is enabled nevertheless in the EEPROM. These patches will be replaced with a future upstream version which will introduces an ieee80211 device tree property to disable bands.

* kernel: mac80211: add pending ath9k EEPROM swapping patchesMartin Blumenstingl2016-11-297-0/+1730
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two types of swapping the EEPROM data in the ath9k driver. Before this series one type of swapping could not be used without the other. The first type of swapping looks at the "magic bytes" at the start of the EEPROM data and performs swab16 on the EEPROM contents if needed. The second type of swapping is EEPROM format specific and swaps specific fields within the EEPROM itself (swab16, swab32 - depends on the EEPROM format). With this series the second part now looks at the EEPMISC register inside the EEPROM, which uses a bit to indicate if the EEPROM data is Big Endian (this is also done by the FreeBSD kernel). This has a nice advantage: currently there are some out-of-tree hacks (in OpenWrt and LEDE) where the EEPROM has a Big Endian header on a Big Endian system (= no swab16 is performed) but the EEPROM itself indicates that it's data is Little Endian. Until now the out-of-tree code simply did a swab16 before passing the data to ath9k, so ath9k first did the swab16 - this also enabled the format specific swapping. These out-of-tree hacks are still working with the new logic, but it is recommended to remove them. This implementation is based on a discussion with Arnd Bergmann who raised concerns about the robustness and portability of the swapping logic in the original OF support patch review, see [0]. After a second round of patches (= v1 of this series) neither Arnd Bergmann nor I were really happy with the complexity of the EEPROM swapping logic. Based on a discussion (see [1] and [2]) we decided that ath9k should use a defined format (specifying the endianness of the data - I went with __le16 and __le32) when accessing the EEPROM fields. A benefit of this is that we enable the EEPMISC based swapping logic by default, just like the FreeBSD driver, see [3]. On the devices which I have tested (see below) ath9k now works without having to specify the "endian_check" field in ath9k_platform_data (or a similar logic which could provide this via devicetree) as ath9k now detects the endianness automatically. Only EEPROMs which are mangled by some out-of-tree code still need the endian_check flag (or one can simply remove that mangling from the out-of-tree code).

* kernel: mac80211: backport ath9k device tree support patchesMartin Blumenstingl2016-11-293-0/+194
| | | | | | | | | | | | | These patches add support for configuring ath9k based devices via devicetree. This was tested on PCI(e) based devices. This should work for AHB based devices as well (adding more AHB specific properties may still be needed) as soon as the ath79 platform is ready to populate the ath9k wmac via devicetree.
