2022-07-15wifi: cfg80211: adjust assoc comeback for MLOJohannes Berg
We only report the BSSID to userspace, so change the argument from BSS struct pointer to AP address, which we'll use to carry either the BSSID or AP MLD address. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: cfg80211: prepare association failure APIs for MLOJohannes Berg
For MLO, we need the ability to report back multiple BSS structures to release, as well as the AP MLD address (if attempting to make an MLO connection). Unify cfg80211_assoc_timeout() and cfg80211_abandon_assoc() into a new cfg80211_assoc_failure() that gets a structure parameter with the necessary data.

2022-07-15wifi: cfg80211: remove BSS pointer from cfg80211_disassoc_requestJohannes Berg
The race described by the comment in mac80211 hasn't existed since the locking rework to use the same lock and for MLO we need to pass the AP MLD address, so just pass the BSSID or AP MLD address instead of the BSS struct pointer, and adjust all the code accordingly.

2022-07-15wifi: nl80211: acquire wdev mutex for dump_surveyJohannes Berg

2022-07-15wifi: cfg80211: drop BSS elements from assoc trace for nowJohannes Berg
For multi-link operation, this cannot work as the req->bss pointer will be NULL, and we'll need to do more work on this to really add tracing for the MLO case here. Drop the BSS elements for now as they're not the most useful thing, and it's hard to size things correctly for the MLO case (without adding a lot of code that's also executed when tracing isn't enabled.)

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.

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")).

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.

2022-06-20cfg80211: 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.)

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: 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.

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 retrieving the S1G channel number from IEs, we should retrieve the operating channel instead of the primary channel. The S1G operation element specifies the main channel of operation as the oper channel, unlike for HT and HE which specify their main channel of operation as the primary channel.

2022-04-11nl80211: show SSID for P2P_GO interfacesJohannes Berg
There's no real reason not to send the SSID to userspace when it requests information about P2P_GO, it is, in that respect, exactly the same as AP interfaces. Fix that.

2022-04-11cfg80211: hold bss_lock while updating nontrans_listRameshkumar Sundaram
Synchronize additions to nontrans_list of transmitting BSS with bss_lock to avoid races. Also when cfg80211_add_nontrans_list() fails __cfg80211_unlink_bss() needs bss_lock to be held (has lockdep assert on bss_lock). So protect the whole block with bss_lock to avoid races and warnings. Found during code review.

2022-04-11nl80211: correctly check NL80211_ATTR_REG_ALPHA2 sizeJohannes Berg
We need this to be at least two bytes, so we can access alpha2[0] and alpha2[1]. It may be three in case some userspace used NUL-termination since it was NLA_STRING (and we also push it out with NUL-termination).
