2020-03-12qtnfmac: set valid edmg in cfg80211_chan_defSergey Matyukevich
Make sure that edmg field of cfg80211_chan_def structure is properly initialized by zeros. Otherwise cfg80211_chandef_valid may return false if edmg fields contain some garbage. Signed-off-by: Sergey Matyukevich <sergey.matyukevich.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2020-03-12qtnfmac: support WPA3 OWE in AP modeSergey Matyukevich
Enable WPA3 OWE support in AP mode. Driver currently supports cards that offload OWE processing to userspace. This patch adds all the required tools for such offloading. Firmware requests OWE processing sending new UPDATE_OWE event to driver, which uses cfg80211_update_owe_info_event to notify userspace software. After OWE processing is completed, userspace sends calculated IEs to firmware using update_owe_info cfg80211 callback.

The tid of 11a station with WMM disable reported by FW is 0x10 in tx completion. The tid 16 is mapped to a NULL txq since buffer MMPDU capbility is not supported. Then 11a station's airtime will not be registered due to NULL txq check. As a results, airtime of 11a station keeps unchanged in debugfs system.

2020-03-11ath11k: config reorder queue for all tids during peer setupGovindaraj Saminathan
Currently rx tid setup is happening for TID 0 and TID 16 during peer setup. And if other TID packets received for the peer it will be redirected to rx error ring and not through reo ring. And this rx tid configuration cannot be done in the rx error ring path since it is a atomic context. So moving the rx tid setup for all tids during the peer setup. This is required to enable PN offload functionality to route all packets through reo ring.

2020-03-11ath10k: fix unsupported chip reset debugs file writeYingying Tang
Before this change, after writing "warm_hw_reset" debugfs file, host will send chip reset command to FW even though FW do not support this service getting a warning print. Though there is no FW impact before this change, this patch restricts chip reset command sent to FW only if FW advertises the support via WMI service bit. Removed the redundant check and ath10k_warn() print as well. New version FW will report chip reset service bit to host. Host allow user to trigger WLAN chip reset only when fw report this service bit. For older NON-TLV FW, since it do not report chip reset service bit, host will not send chip reset command. For older TLV FW, since it report chip reset service bit, host will send chip reset command.

2020-03-11ath10k: avoid consecutive OTP download to reduce boot timeVikas Patel
Currently, OTP is downloaded twice in case of "pre-cal-dt" and "pre-cal-file" to fetch the board ID and takes around ~2 sec more boot uptime. First OTP download happens in "ath10k_core_probe_fw" and second in ath10k_core_start. First boot does not need OTP download in core start when valid board id acquired. The second OTP download is required upon core stop/start. This patch skips the OTP download when first OTP download has acquired a valid board id. This patch also marks board id invalid in "ath10k_core_stop", which will force the OTP download in ath10k_core_start and fetches valid board id.

2020-03-03mt76: fix array overflow on receiving too many fragments for a packetFelix Fietkau
If the hardware receives an oversized packet with too many rx fragments, skb_shinfo(skb)->frags can overflow and corrupt memory of adjacent pages. This becomes especially visible if it corrupts the freelist pointer of a slab page.

2020-02-24mac80211_hwsim: enable Beacon protectionJouni Malinen
Now that there is support for BIGTK configuration and AP/STA functionality for using BIP with Beacon frames, indicate support for the Beacon protection functionality. Johannes: move this to hwsim, since it's not clear that all drivers using mac80211 will do this correctly - lots of them modify the beacon before transmission e.g. to update the TIM element, and that would obviously break the signature.

2020-02-14mt76: mt7615: rework rx phy index handlingFelix Fietkau
Overwriting the RMAC_CHFREQ register is not reliable enough, as the firmware could potentially write it again. Since there is no PHY index indication in the rx info, we need to use another way: If both PHYs are using different channels, find the PHY where chfreq matches the register value. The only corner case remaining is when both PHYs are using the same channel. In that case, the per-packet noise value on the primary PHY will have information belonging to the chains of the secondary PHY from the previous received packet of that PHY. The secondary PHY will set noise to 0 for extra chains. Signed-off-by: Felix Fietkau <nbd@nbd.name>
