wifi: mac80211: make monitor link info check more specific

2025-11-11T10:05:19Z

Verify that only one of the permitted change flags is set when changing the link of a monitor interface. Before the WARN_ON_ONCE would accept anything if mu_mimo_owner was set. Also, split out the mu_mimo_owner flag and enable it for all interface types. The option is set during association when VHT is available and it is not expected that any configuration of the MU groups is done without it being set.

wifi: mac80211: correctly initialise S1G chandef for STA

2025-09-19T09:56:07Z

When moving to the APs channel, ensure we correctly initialise the chandef and perform the required validation. Additionally, if the AP is beaconing on a 2MHz primary, calculate the 2MHz primary center frequency by extracting the sibling 1MHz primary and averaging the frequencies to find the 2MHz primary center frequency.

wifi: mac80211: Support Tx of action frame for NAN

2025-09-19T09:26:22Z

Add support for sending management frame over a NAN Device interface: - Declare support for the supported management frames types. - Since action frame transmissions over a NAN Device interface do not necessarily require a channel configuration, e.g., they can be transmitted during DW, modify the Tx path to avoid accessing channel information for NAN Device interface. - In addition modify the points in the Tx path logic to account for cases that a band is not specified in the Tx information.

wifi: drivers: indicate support for attributes in NL80211_CMD_SET_BSS

2025-09-04T09:19:02Z

The command NL80211_CMD_SET_BSS has a number of individual attributes and the driver can advertise which of those it will handle when it is changed by user-space. For drivers providing an empty .change_bss() the callback has been removed.

wifi: mac80211: increase scan_ies_len for S1G

2025-08-26T11:47:21Z

Currently the S1G capability element is not taken into account for the scan_ies_len, which leads to a buffer length validation failure in ieee80211_prep_hw_scan() and subsequent WARN in __ieee80211_start_scan(). This prevents hw scanning from functioning. To fix ensure we accommodate for the S1G capability length.

wifi: mac80211: fix WARN_ON for monitor mode on some devices

2025-07-23T10:29:07Z

On devices without WANT_MONITOR_VIF (and probably without channel context support) we get a WARN_ON for changing the per-link setting of a monitor interface. Since we already skip AP_VLAN interfaces and MONITOR with WANT_MONITOR_VIF and/or NO_VIRTUAL_MONITOR should update the settings, catch this in the link change code instead of the warning.

wifi: cfg80211/mac80211: remove wrong scan request n_channels

2025-07-18T12:07:35Z

This (partially) reverts commits - 838c7b8f1f27 ("wifi: nl80211: Avoid address calculations via out of bounds array indexing") - f1d3334d604c ("wifi: cfg80211: sme: init n_channels before channels[] access") - 82bbe02b2500 ("wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request") These commits all set the structure to be in an inconsistent state, setting n_channels to some value before them actually being filled in. That's fine for what the code does now, but with the removal of __counted_by() in 444020f4bf06 ("wifi: cfg80211: remove scan request n_channels counted_by") it's no longer needed and it does leave a bit of a landmine there since breaking out of some code to send the scan or something would leave it wrong. Remove the now superfluous n_channels settings. Link: https://patch.msgid.link/20250718103237.59510b2384c5.Ied5ba9c5c49efc008f4491c8ca7a45858a83f064@changeid Signed-off-by: Johannes Berg

wifi: mac80211: clean up cipher suite handling

2025-07-15T09:00:39Z

Under the previous commit's assumption that FIPS isn't supported by hardware, we don't need to modify the cipher suite list, but just need to use the software one instead of the driver's in this case, so clean up the code. Also fix it to exclude TKIP in this case, since that's also dependent on RC4.
