2018-03-29mac80211: limit wmm params to comply with ETSI requirementsHaim Dreyfuss
ETSI has recently added new requirements that restrict the WMM parameter values for 5GHz frequencies. We need to take care of the following scenarios in order to comply with these new requirements: 1. When using mac80211 default values; 2. When the userspace tries to configure its own values; 3. When associating to an AP which advertises WWM IE. When associating to an AP, the client uses the values in the advertised WMM IE. But the AP may not comply with the new ETSI requirements, so the client needs to check the current regulatory rules and use those limits accordingly.

2018-03-29cfg80211: don't require RTNL held for regdomain readsJohannes Berg
The whole code is set up to allow RCU reads of this data, but then uses rtnl_dereference() which requires the RTNL. Convert it to rcu_dereference_rtnl() which makes it require only RCU or the RTNL, to allow RCU-protected reading of the data.

2018-03-29cfg80211: read wmm rules from regulatory databaseHaim Dreyfuss
ETSI EN 301 893 v2.1.1 (2017-05) standard defines a new channel access mechanism that all devices (WLAN and LAA) need to comply with. The regulatory database can now be loaded into the kernel and also has the option to load optional data. In order to be able to comply with ETSI standard, we add wmm_rule into regulatory rule and add the option to read its value from the regulatory database.

2018-03-29ath10k: fix vdev stats for 10.4 firmwareRajkumar Manoharan
Currently vdev stats displayed in fw_stats are applicable only for TLV based firmware and fix it for 10.4 firmware as of now. The vdev stats in 10.4 firmware is split into two parts (vdev_stats, vdev_stats_extended). The actual stats are captured only in extended vdev stats. In order to enable vdev stats, appropriate feature bit will be set on extended resource config. As FTM related counters are available only on newer 10.4 based firmware, these counters will be displayed only on valid data.

2018-03-29wcn36xx: dequeue all pending indicator messagesDaniel Mack
In case wcn36xx_smd_rsp_process() is called more than once before hal_ind_work was dispatched, the messages will end up in hal_ind_queue, but wcn36xx_ind_smd_work() will only look at the first message in that list.

2018-03-29wcn36xx: Fix firmware crash due to corrupted buffer addressLoic Poulain
wcn36xx_start_tx function retrieves the buffer descriptor from the channel control queue to start filling tx buffer information. However, nothing prevents this same buffer to be concurrently accessed in a concurent tx call, leading to potential buffer coruption and firmware crash (observed during iperf test). The channel control queue should only be accessed and updated with the channel lock. Fix this issue by using a local buffer descriptor which will be copied in the thread-safe wcn36xx_dxe_tx_frame. Note that buffer descriptor size is few bytes so the introduced copy overhead is insignificant. Moreover, this allows to keep the locked section minimal.

2018-03-29Revert "ath10k: send (re)assoc peer command when NSS changed"Karthikeyan Periyasamy
This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159. When Ath10k is in AP mode and an unassociated STA sends a VHT action frame (Operating Mode Notification for the NSS change) periodically to AP this causes ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during NSS update. Over the time (with a certain client it can happen within 15 mins when there are over 500 of these VHT action frames) continuous calls of WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust. To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS updates and no need to call ath10k_station_assoc(). So revert the original commit from 2014 as it's unclear why the change was really needed. Now the firmware assert doesn't happen anymore. Issue observed in QCA9984 platform with firmware version:10.4-3.5.3-00053. This Change tested in QCA9984 with firmware version: 10.4-3.5.3-00053 and QCA988x platform with firmware version: 10.2.4-1.0-00036. Firmware Assert log: ath10k_pci 0002:01:00.0: firmware crashed!

2018-03-29ath9k: fix DFS detector synchronizationTimothy Redaelli
some userspace programs (e.g. hostapd) need to set the regulatory domain before selecting the operating channel. Synchronize DFS detector regardless of the value of ah->curchan, to avoid situations where wireless scan can't be done on some 5GHz sub-bands, because dfs_region is constantly UNSET.

Map the mac80211 specific value to nl80211_chan_width enum value to avoid using wrong value in the userspace application.
