For an AP interface, when userspace specifieds the link ID to transmit the control port frame on (in particular for the initial 4-way-HS), due to the logic in ieee80211_build_hdr() for a frame transmitted from/to an MLD, we currently build a header with A1 = DA = MLD address of the peer MLD A2 = local link address (!) A3 = SA = local MLD address This clearly makes no sense, and leads to two problems: - if the frame were encrypted (not true for the initial 4-way-HS) the AAD would be calculated incorrectly - if iTXQs are used, the frame is dropped by logic in ieee80211_tx_dequeue() Fix the addressing, which fixes the first bullet, and the second bullet for peer MLDs, I'll fix the second one for non-MLD peers separately.

The code for determining which links to update in wmediumd or virtio was wrong, fix it to remove the deflink only if there were no old links, and also add the deflink if there are no other new links. Fixes: c204d9df ("wifi: mac80211_hwsim: handle links for wmediumd/virtio") Signed-off-by:

For AP/non-AP the EHT MCS/NSS subfield size differs, the 4-octet subfield is only used for 20 MHz-only non-AP STA. Pass an argument around everywhere to be able to parse it properly. Signed-off-by: -

The next patch will require splitting the data here into AP and non-AP because for EHT, the format of the MCS/NSS support (struct ieee80211_eht_mcs_nss_supp) is different, for AP the only_20mhz cannot be used. Signed-off-by: -

When queuing frames to an interface store the link ID we determined (which possibly came from the driver in the RX status in the first place) in the RX status, and use it in the MLME code to send probe responses, beacons and CSA frames to the right link. Signed-off-by: -

In MLO, when the address translation from link to MLD is done in fw/hw, it is necessary to be able to have some information on the link on which the frame has been received. Extend the rx API to include link_id and a valid flag in ieee80211_rx_status. Also make chanes to mac80211 rx APIs to make use of the reported link_id after sanity checks. Signed-off-by:

Add support for various key operations on MLD by adding new parameter link_id. Pass the link_id received from userspace to driver for add_key, get_key, del_key, set_default_key, set_default_mgmt_key and set_default_beacon_key to support configuring keys specific to each MLO link. Userspace must not specify link ID for MLO pairwise key since it is common for all the MLO links. Signed-off-by:

If there's no link ID, then check that there are no changes to the link, and if so accept them, unless a new link is created. While at it, reject creating a new link without an address. This fixes authorizing an MLD (peer) that has no link 0. Signed-off-by:

Enter or leave IPS controlled by mac80211 before driver support HW scan. After support HW scan, driver need to control IPS before start HW scan and scan complete, but mac80211 also ask driver enter or leave IPS. Therefore, we add flag check in IPS to prevent entering or leaving IPS twice. Signed-off-by:

Since IQK could spend time, we make a cache of IQK result matrix that looks like iqk_matrix[channel_idx].val[x][y], and we can reload the matrix if we have made a cache. To determine a cache is made, we check iqk_matrix[channel_idx].val[0][0]. The initial commit 7274a8c2 ("rtlwifi: rtl8192de: Merge phy routines") make a mistake that checks incorrect iqk_matrix[channel_idx].val[0] that is always true, and this mistake is found by commit ee3db469 ("wifi: rtlwifi: remove always-true condition pointed out by GCC 12"), so I recall the vendor driver to find fix and apply the correctness.

Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS. Signed-off-by:
