A comment in cfg80211_mlme_mgmt_tx() is describing this API used only for transmitting action frames. Fix the comment since cfg80211_mlme_mgmt_tx() can be used to transmit any management frame.

2022-07-01wifi: cfg80211: Increase akm_suites array size in cfg80211_crypto_settingsVeerendranath Jakkam
Increase akm_suites array size in struct cfg80211_crypto_settings to 10 and advertise the capability to userspace. This allows userspace to send more than two AKMs to driver in netlink commands such as NL80211_CMD_CONNECT. This capability is needed for implementing WPA3-Personal transition mode correctly with any driver that handles roaming internally. Currently, the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256, SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing the akm_suites array size to 10 should be reasonable for future usecases.

2022-07-01wifi: cfg80211: remove chandef check in cfg80211_cac_event()Johannes Berg
The current check only worked for AP mode, but we can do radar detection in mesh as well (for example). We could try to check this using wdev_chandef(), but we also don't really care since the chandef is passed in and we have no need to use it anymore (since we added the argument in commit d2859df5e7f0 ("cfg80211/mac80211: DFS setup chandef for cac event")).

2022-07-01wifi: nl80211: relax wdev mutex check in wdev_chandef()Johannes Berg
In many cases we might get here from driver code that's not really set up to care about the locking, and for the non-MLO cases we really don't care so much about it. So relax the checking here for now, perhaps we should even remove it completely since we might not really care if we point to an invalid link's chandef and can require the caller to check the link validity first.

2022-06-29wifi: cfg80211: Allow P2P client interface to indicate port authorizationVinayak Yadawad
In case of 4way handshake offload, cfg80211_port_authorized enables driver to indicate successful 4way handshake to cfg80211 layer.

2022-06-20cfg80211: Indicate MLO connection info in connect and roam callbacksVeerendranath Jakkam
The MLO links used for connection with an MLD AP are decided by the driver in case of SME offloaded to driver. Add support for the drivers to indicate the information of links used for MLO connection in connect and roam callbacks, update the connected links information in wdev from connect/roam result sent by driver. Also, send the connected links information to userspace. Add a netlink flag attribute to indicate that userspace supports handling of MLO connection. Drivers must not do MLO connection when this flag is not set. This is to maintain backwards compatibility with older supplicant versions which doesn't have support for MLO connection.

2022-06-20wifi: cfg80211: add optional link add/remove callbacksJohannes Berg
Add some optional callbacks for link add/remove so that drivers can react here. Initially, I thought it would be sufficient to just create the link in start_ap etc., but it turns out that's not so simple, since there are quite a few callbacks that can be called: if they're erroneously without start_ap, things might crash. Thus it might be easier for drivers to allocate all the necessary data structures immediately, to not have to worry about it in each callback, since cfg80211 checks that the link ID is valid (has been added.)

We wanted to have this sorted by direction (to/from driver), but didn't maintain that well. Sort the file now. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-06-20wifi: nl80211: support MLO in auth/assocJohannes Berg
For authentication, we need the BSS, the link_id and the AP MLD address to create the link and station, (for now) the driver assigns a link address and sends the frame, the MLD address needs to be the address of the interface. For association, pass the list of BSSes that were selected for the MLO connection, along with extra per-STA profile elements, the AP MLD address and the link ID on which the association request should be sent. Note that for now we don't have a proper way to pass the link address(es) and so the driver/mac80211 will select one, but depending on how that selection works it means that assoc w/o auth data still being around (mac80211 implementation detail) the association won't necessarily work - so this will need to be extended in the future to sort out the link addressing.

2022-06-20wifi: cfg80211: mlme: get BSS entry outside cfg80211_mlme_assoc()Johannes Berg
Today it makes more sense to pass the necessary parameters to look up the BSS entry to cfg80211_mlme_assoc(), but with MLO we will need to look up multiple, and that gets awkward. Pull the lookup code into the callers so we can change it better. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-06-20wifi: cfg80211: do some rework towards MLO link APIsJohannes Berg
In order to support multi-link operation with multiple links, start adding some APIs. The notable addition here is to have the link ID in a new nl80211 attribute, that will be used to differentiate the links in many nl80211 operations. So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID attribute (as well as the NL80211_ATTR_MLO_LINKS attribute) and plugs it through the system in some places, checking the validity etc. along with other infrastructure needed for it. For now, I've decided to include only the over-the-air link ID in the API. I know we discussed that we eventually need to have to have other ways of identifying a link, but for local AP mode and auth/assoc commands as well as set_key etc. we'll use the OTA ID. Also included in this patch is some refactoring of the data structures in struct wireless_dev, splitting for the first time the data into type dependent pieces, to make reasoning about these things easier.

2022-05-04nl80211: rework internal_flags usageJohannes Berg
Since internal_flags is only 8 bits, we can only have one more internal flag. However, we can obviously never use all of possible the combinations, in fact, we only use 14 of them (including no flags). Since we want more flags for MLO (multi-link operation) in the future, refactor the code to use a flags selector, so wrap all of the .internal_flags assignments in a IFLAGS() macro which selects the combination according to the pre- defined list of combinations. When we need a new combination, we'll have to add it, but again we will never use all possible combinations.

2022-03-02nl80211: Update bss channel on channel switch for P2P_CLIENTSreeramya Soratkal
The wdev channel information is updated post channel switch only for the station mode and not for the other modes. Due to this, the P2P client still points to the old value though it moved to the new channel when the channel change is induced from the P2P GO. Update the bss channel after CSA channel switch completion for P2P client interface as well.
