2023-12-21wifi: cfg80211: avoid double free if updating BSS failsBenjamin Berg1-4/+3
cfg80211_update_known_bss will always consume the passed IEs. As such, cfg80211_update_assoc_bss_entry also needs to always set the pointers to NULL so that no double free can occur. Note that hitting this would probably require being connected to a hidden BSS which is then doing a channel switch while also switching to be not hidden anymore at the same time.

2023-12-21wifi: cfg80211: ensure cfg80211_bss_update frees IEs on errorBenjamin Berg1-14/+16
cfg80211_bss_update is expected to consume the IEs that are passed into it in the temporary internal BSS.

This is a more of a cosmetic fix. The branch will only be taken if proberesp_ies is set, which implies that beacon_ies is not set unless we are connected to an AP that just did a channel switch.

2023-12-12wifi: cfg80211: add BSS usage reportingJohannes Berg3-28/+102
Sometimes there may be reasons for which a BSS that's actually found in scan cannot be used to connect to, for example a nonprimary link of an NSTR mobile AP MLD cannot be used for normal direct connections to it. Not indicating these to userspace as we do now of course avoids being able to connect to them, but it's better if they're shown to userspace and it can make an appropriate decision, without e.g. doing an additional ML probe. Thus add an indication of what a BSS can be used for, currently "normal" and "MLD link", including a reason bitmap for it being not usable. The latter can be extended later for certain BSSes if there are other reasons they cannot be used.

Given all the locking rework in mac80211, we pretty much need to get into the driver with the wiphy mutex held in all callbacks. This is already mostly the case, but as Johan reported, in the get_txpower it may not be true. Lock the wiphy mutex around nl80211_send_iface(), then is also around callers of nl80211_notify_iface().

2023-11-24wifi: cfg80211: fix CQM for non-range useJohannes Berg2-19/+32
My prior race fix here broke CQM when ranges aren't used, as the reporting worker now requires the cqm_config to be set in the wdev, but isn't set when there's no range configured. Rather than continuing to special-case the range version, set the cqm_config always and configure accordingly, also tracking if range was used or not to be able to clear the configuration appropriately with the same API, which was actually not right if both were implemented by a driver for some reason, as is the case with mac80211 (though there the implementations are equivalent so it doesn't matter.) Also, the original multiple-RSSI commit lost checking for the callback, so might have potentially crashed if a driver had neither implementation, and userspace tried to use it despite not being advertised as supported.

cfg80211_rx_assoc_resp_data make htmldocs warns: Documentation/driver-api/80211/cfg80211:48: ./include/net/cfg80211.h:7290: WARNING: Duplicate C declaration, also defined at cfg80211:7251. Declaration is '.. c:function:: void cfg80211_rx_assoc_resp (struct net_device *dev, struct cfg80211_rx_assoc_resp *data)'. This is because there's a function named cfg80211_rx_assoc_resp() and a struct named cfg80211_rx_assoc_resp, see previous patch for more info. To workaround this rename the struct to cfg80211_rx_assoc_resp_data. The parameter for the function is named 'data' anyway so the naming here is consistent. Compile tested only.

2023-10-23wifi: cfg80211: Handle specific BSSID in 6GHz scanningIlan Peer1-0/+37
When the scan parameters for a 6GHz scan specify a unicast BSSID address, and the corresponding AP is found in the scan list, add a corresponding entry in the collocated AP list, so this AP would be directly probed even if it was not advertised as a collocated AP. This is needed for handling a scan request that is intended for a ML probe flow, where user space can requests a scan to retrieve information for other links in the AP MLD.

Since wiphy work items can run pretty much arbitrary code in the stack/driver, it can take longer to run all of this, so we shouldn't be using system_wq via schedule_work(). Also, we lock the wiphy (which is the reason this exists), so use system_unbound_wq.

If the structure is not initialized then boolean types might be copied into the tracing data without being initialised. This causes data from the stack to leak into the trace and also triggers a UBSAN failure which can easily be avoided here.

2023-09-25wifi: cfg80211: report per-link errors during associationBenjamin Berg1-6/+44
When one of the links (other than the assoc_link) is misconfigured and cannot work the association will fail. However, userspace was not able to tell that the operation only failed because of a problem with one of the links. Fix this, by allowing the driver to set a per-link error code and reporting the (first) offending link by setting the bad_attr accordingly. This only allows us to report the first error, but that is sufficient for userspace to e.g. remove the offending link and retry.

2023-09-13wifi: cfg80211: export DFS CAC time and usable state helper functionsAditya Kumar Singh2-17/+2
cfg80211 has cfg80211_chandef_dfs_usable() function to know whether at least one channel in the chandef is in usable state or not. Also, cfg80211_chandef_dfs_cac_time() function is there which tells the CAC time required for the given chandef. Make these two functions visible to drivers by exporting their symbol to global list of kernel symbols. Lower level drivers can make use of these two functions to be aware if CAC is required on the given chandef and for how long. For example drivers which maintains the CAC state internally can make use of these.

2023-09-13wifi: cfg80211: call reg_call_notifier on beacon hintsAbhishek Kumar1-8/+12
Currently the channel property updates are not propagated to driver. This causes issues in the discovery of hidden SSIDs and fails to connect to them. This change defines a new wiphy flag which when enabled by vendor driver, the reg_call_notifier callback will be trigger on beacon hints. This ensures that the channel property changes are visible to the vendor driver. The vendor changes the channels for active scans. This fixes the discovery issue of hidden SSID.

2023-09-13wifi: cfg80211: allow reg update by driver even if wiphy->regd is setRaj Kumar Bhagat1-5/+4
Currently regulatory update by driver is not allowed when the wiphy->regd is already set and drivers_request->intersect is false. During wiphy registration, some drivers (ath10k does this currently) first register the world regulatory to cfg80211 using wiphy_apply_custom_regulatory(). The driver then obtain the current operating country and tries to update the correct regulatory to cfg80211 using regulatory_hint(). But at this point, wiphy->regd is already set to world regulatory. Also, since this is the first request from driver after the world regulatory is set this will result in drivers_request->intersect set to false. In this condition the driver request regulatory is not allowed to update to cfg80211 in reg_set_rd_driver(). This restricts the device operation to the world regulatory. This driver request to update the regulatory with current operating country is valid and should be updated to cfg80211. Hence allow regulatory update by driver even if the wiphy->regd is already set and driver_request->intersect is false.
