2022-12-01wifi: mt76: add info parameter to rx_skb signatureSujuan Chen1-1/+1

2022-12-01wifi: mt76: mt7921: introduce chanctx supportSean Wang1-8/+0
The firmware can have the capability to manage the channel context scheduling on multiple roles running on the device including Station, AP and P2P GC/GO mode (will be extended based on the future patchset) to help users sharing the network with others on a single device. The firmware is able to support the channel chanctx up to 2 interface simultaneously running on the different channels. Another thing to be noted is that before the driver is going sent out the management frames, the driver has to get the privilege from the firmware to occupy the current channel context until the frame handshake is completed and then get the privilege back to the firmware.

2022-12-01wifi: mt76: mt7921: fix antenna signal are way off in monitor modeSean Wang1-11/+21
Group 3 in RxD is disabled in monitor mode. We should use the group 5 in RxD instead to fix antenna signal way off issue, e.g we would see the incorrect antenna signal value in wireshark. On the other hand, Group 5 wouldn't be used in STA or AP mode, so the patch shouldn't cause any harm to those modes.

Checking the relevant rxd bits for the checksum information only indicates if the checksum verification was performed by the hardware and doesn't show actual checksum errors. Checksum errors are indicated in the info field of the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY by checking the extra bits as well. Those bits are only passed to the driver for MMIO devices at the moment, so limit checksum offload to those.

2022-09-15wifi: mt76: mt7921e: fix race issue between reset and suspend/resumeSean Wang1-0/+5
It is unexpected that the reset work is running simultaneously with the suspend or resume context and it is possible that reset work is still running even after mt7921 is suspended if we don't fix the race issue. Thus, the suspend procedure should be waiting until the reset is completed at the beginning and ignore the subsequent the reset requests. In case there is an error that happens during either suspend or resume handler, we will schedule a reset task to recover the error before returning the error code to ensure we can immediately fix the error there.

2022-04-11mac80211: prepare sta handling for MLO supportSriram R1-1/+1
Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2021-12-19mt76: do not pass the received frame with decryption errorXing Song1-1/+8
MAC80211 doesn't care any decryption error in 802.3 path, so received frame will be dropped if HW tell us that the cipher configuration is not matched as well as the header has been translated to 802.3. This case only appears when IEEE80211_FCTL_PROTECTED is 0 and cipher suit is not none in the corresponding HW entry. The received frame is only reported to monitor interface if HW decryption block tell us there is ICV error or CCMP/BIP/WPI MIC error. Note in this case the reported frame is decrypted 802.11 frame and the payload may be malformed due to mismatched key.
