2023-04-20wifi: iwlwifi: modify scan request and results when in link protectionAvraham Stern1-0/+78
When CSME is connected and has link protection set, the driver must connect to the same AP CSME is connected to. When in link protection, modify scan request parameters to include only the channel of the AP CSME is connected to and scan for the same SSID. In addition, filter the scan results to include only results from the same AP. This will make sure the driver will connect to the same AP and will do it fast enough to keep the session alive.

2023-03-30wifi: iwlwifi: mvm: vif preparation for MLOGregory Greenman1-7/+8
In MLO, some fields of iwl_mvm_vif should be defined in the context of a link. Define a separate structure for these fields and add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy code will use only deflink object while MLO related code will use the corresponding link from the link array. It follows the strategy applied in mac80211 for introducing MLO changes. The below spatch takes care of updating all driver code to access fields separated into MLD specific data structure via deflink (need to convert all references to the fields listed in var to deflink.var and also to take care of calls like iwl_mvm_vif_from_mac80211(vif)->field). @iwl_mld_vif@ struct iwl_mvm_vif *v; struct ieee80211_vif *vv; identifier fn; identifier var = {bssid, ap_sta_id, bcast_sta, mcast_sta, beacon_stats, smps_requests, probe_resp_data, he_ru_2mhz_block, cab_queue, phy_ctxt, queue_params}; @@ ( v-> - var + deflink.var | fn(vv)-> - var + deflink.var ) Signed-off-by: Gregory Greenman <[email protected]> Link: https://lore.kernel.org/r/20230328104948.4896576f0a9f.Ifaf0187c96b9fe52b24bd629331165831a877691@changeid Signed-off-by: Johannes Berg <[email protected]>
2022-09-28wifi: iwlwifi: Track scan_cmd allocation size explicitlyKees Cook1-3/+3
In preparation for reducing the use of ksize(), explicitly track the size of scan_cmd allocations. This also allows for noticing if the scan size changes unexpectedly. Note that using ksize() was already incorrect here, in the sense that ksize() would not match the actual allocation size, which would trigger future run-time allocation bounds checking. (In other words, memset() may know how large scan_cmd was allocated for, but ksize() will return the upper bounds of the actually allocated memory, causing a run-time warning about an overflow.)

2022-02-18iwlwifi: mvm: Consider P2P GO operation during scanIlan Peer1-3/+129
A scan during active P2P GO operation, i.e., data traffic with clients, can impact the throughput and latency of such traffic. Thus, when scan is requested while there is an active P2P GO and low latency is asserted: - Ask the FW scan logic to respect the P2P GO activity during the scheduling of the scan operation to minimize the impact on the throughput and latency. - Force scan to perform EBS before starting the scan to reduce the number of scanned channels.

2022-02-18iwlwifi: mvm: Passively scan non PSC channels only when requested soIlan Peer1-10/+32
Non PSC channels should generally be scanned based on information about collocated APs obtained during scan on legacy bands, and otherwise should not be scanned unless specifically requested so (as there are relatively many non PSC channels, scanning them passively is time consuming and interferes with regular data traffic). Thus, modify the scan logic to avoid passively scanning PSC channels if there is no information about collocated APs and the scan is not a passive scan.

2021-08-26iwlwifi: mvm: Add support for hidden network scan on 6GHz bandIlan Peer1-15/+75
Add support for discovery of hidden networks on the 6GHz band, by including the scan request direct SSIDs in the FW scan request command: - In case a short SSID matches one of the direct SSIDs in the scan request command, add the matching SSID in the same offset in the 'direct_ssids' array. - Otherwise, add the SSID in one of the available slots. Additionally, as a preparation to handle hidden APs, refactor iwl_mvm_umac_scan_cfg_channels_v6_6g() the function.

2021-04-14iwlwifi: mvm: Add support for 6GHz passive scanIlan Peer1-0/+128
When doing scan while 6GHz channels are not enabled, the 6GHz band is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands (that will allow discovery of geographic location etc. that would allow enabling the 6GHz channels) but there are non collocated APs on 6GHz PSC channels these would never be discovered. To overcome this, FW added support for performing passive UHB scan in case no APs were discovered during scan on the 2GHz and 5GHz channels. Add support for enabling such scan when the following conditions are met: - 6GHz channels are supported but not enabled by regulatory. - Station interface is not associated or less than a defined time interval passed from the last resume or HW reset flows. - At least 4 channels are included in the scan request - The scan request includes the widlcard SSID. - At least 50 minutes passed from the last 6GHz passive scan.

When restarting firmware with an ongoing scheduled scan, we don't (and shouldn't) mark it as aborted as mac80211 will be restarting it, and so no event should go out to userspace. The appropriate comment regarding this wasn't moved to this place, so add it.

2020-10-01iwlwifi: mvm: ignore the scan duration parameterAvraham Stern1-45/+10
The scan request may specify the request scan dwell time. However, this value may not always be optimal (e.g. short dwell time for a passive channel). This may happen in a scan request as a result of beacon report request, in which the AP may request an active scan, thus setting a short dwell time, but the station will perform a passive scan due to regulatory. Ignore the scan duration parameter and always use the internal scan dwell time which should be optimal.
