2022-07-15wifi: cfg80211: adjust assoc comeback for MLOJohannes Berg4-11/+11
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: mac80211: mlme: unify assoc data event sendingJohannes Berg1-31/+20
There are a few cases where we send an event to cfg80211 manually, but ieee80211_destroy_assoc_data() also handles the case of abandoning; some cases don't need an event and success is handled yet differently. Unify this by providing a single status argument to the ieee80211_destroy_assoc_data() function and then handling all the different cases of events (or no events) there. This will help simplify the code when MLO support is added. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: cfg80211: prepare association failure APIs for MLOJohannes Berg4-37/+75
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: cfg80211: remove BSS pointer from cfg80211_disassoc_requestJohannes Berg5-22/+13
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: mlme: use correct link_staJohannes Berg1-17/+33
For station capabilities, e.g. TWT, we need to use the correct link station instead of deflink. Switch the code to do that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: mlme: remove sta argument from ieee80211_config_bwJohannes Berg1-5/+1
The argument is unused except for NULL checking, but we already do that anyway, so it's not needed. Remove the argument. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: mlme: use ieee80211_get_link_sband()Johannes Berg2-6/+8
This requires a few more changes. While at it, also add a warning to ieee80211_get_sband() to avoid it being used when there are multiple links. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: split IEEE80211_STA_DISABLE_WMM to link dataJohannes Berg2-5/+6
If we decide to stop tracking QoS/WMM parameters, then this should be a per-link decision. Move the flag to the link instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: mlme: first adjustments for MLOJohannes Berg3-363/+408
Do the first adjustments in the client-side code to pass the link pointer (instead of sdata) to most places etc. This is just preparation, so the real MLO patches become smaller. Note that this isn't complete, notably there are still quite a few references to sta->deflink and sta->sta.deflink. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: mlme: do IEEE80211_STA_RESET_SIGNAL_AVE per linkJohannes Berg2-5/+4
Remove the IEEE80211_STA_RESET_SIGNAL_AVE flag and use a bool instead, but invert the polarity (now calling it tracking_signal_avg) so we don't have to initialize it, and put that into the link instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: mlme: track AP (MLD) address separatelyJohannes Berg2-14/+19
To prepare a bit more for MLO in the client code, track the AP's address (for now only the BSSID, but will track the AP MLD's address later) separately from the per-link BSSID. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: remove unused bssid variableJohannes Berg1-2/+0
This variable is only written to, remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: change QoS settings API to take link into accountJohannes Berg55-104/+158
Take the link into account in the QoS settings (EDCA parameters) APIs. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: expect powersave handling in driver for MLOJohannes Berg2-2/+5
In MLO, expect the driver fully handles powersave handling, including tracking whether or not a beacon was received, the DTIM period, etc. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: move ps setting to vif configJohannes Berg13-22/+22
This really shouldn't be in a per-link config, we don't want to let anyone control it that way (if anything, link powersave could be forced through APIs to activate/deactivate a link), and we don't support powersave in software with devices that can do MLO. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: provide link ID in link_confJohannes Berg2-0/+3
It might be useful to drivers to be able to pass only the link_conf pointer, rather than both the pointer and the link_id; add the link_id to the link_conf to facility that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: set up/tear down client vif links properlyJohannes Berg3-151/+232
In station/client mode, the link data needs a bit more initialization and destruction than just zero-init and kfree() respectively, implement that. This required some shuffling of the link data handling in general, as we should set it up in setup and do the teardown in teardown, otherwise we're asymmetric in case of interface type changes. Also stop using kfree_rcu(), we cannot guarantee that nothing is scheduling things that live within the link (e.g. the u.mgd.request_smps_work) until we're sure it cannot be referenced anymore, therefore synchronize instead. This isn't very efficient, but we can always optimize it later. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: move ieee80211_request_smps_mgd_workJohannes Berg3-13/+12
This function can be static. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: nl80211: acquire wdev mutex for dump_surveyJohannes Berg1-0/+2
At least the quantenna driver calls wdev_chandef() here which now requires the lock, so acquire it. Fixes: 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link APIs") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: fix key lookupJohannes Berg1-0/+4
With the split into keys[]/deflink.gtk[] arrays, WEP keys are still installed into the keys[] array, but we didn't look them up there. This meant they weren't deleted correctly. Fix this by looking up the key there even if it's not pairwise so we can be sure we don't have it. Fixes: bfd8403adddd ("wifi: mac80211: reorg some iface data structs for MLD") Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: separate out connection downgrade flagsJohannes Berg7-209/+221
Separate out the connection downgrade flags from the ifmgd->flags and put them into the link information instead. While at it, make them a separate sparse type so we don't get confused about where they belong and have static checking on correct handling. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2022-07-15wifi: mac80211: skip powersave recalc if driver SUPPORTS_DYNAMIC_PSJohannes Berg1-1/+2
There are a few places that check ps_sdata and/or the dynamic PS timeout, but they're erroneous in case SUPPORTS_DYNAMIC_PS is set by the driver. Skip the entire recalculation in this case so we cannot get into those paths elsewhere, and so we simplify this for the purpose of implementing MLO. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: debug: omit link if non-MLO connectionJohannes Berg1-6/+25
If we don't really have multiple links, omit the link ID from link debug prints, otherwise we change the format for all of the existing drivers (most of which might never support MLO), and also have extra noise in the logs. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2022-07-15wifi: cfg80211: drop BSS elements from assoc trace for nowJohannes Berg2-21/+3
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.)

2022-07-15wifi: cfg80211: make cfg80211_auth_request::key_idx signedJohannes Berg1-1/+2
We might assign -1 to it in some cases when key is NULL, which means the key_idx isn't used but can lead to a warning from static checkers such as smatch. Make the struct member signed simply to avoid that, we only need a range of -1..3 anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: nl80211: enable setting the link address at new stationShaul Triebitz1-1/+19
Since for an MLD station the default link is added together with the add station command, allow also setting the link MAC address. Otherwise, it is needed to use the modify link API only for setting the link MAC address. Signed-off-by: Shaul Triebitz <shaul.triebitz@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: mac80211: RCU-ify link/link_conf pointersJohannes Berg22-275/+420
Since links can be added and removed dynamically, we need to somehow protect the sdata->link[] and vif->link_conf[] array pointers from disappearing when accessing them without locks. RCU-ify the pointers to achieve this, which requires quite a bit of rework. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: nl80211: hold wdev mutex for station APIsJohannes Berg1-1/+10
Since this will need to refer - at least in part - to the link stations of an MLD, hold the wdev mutex for driver convenience. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: nl80211: hold wdev mutex for channel switch APIsJohannes Berg1-5/+16
Since we deal with links in an MLD here, hold the wdev mutex now. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-07-15wifi: nl80211: hold wdev mutex in add/mod/del link stationJohannes Berg1-3/+13
Since we deal with links, and that requires looking at wdev links, we should hold the wdev mutex for driver convenience. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Put the link_station_parameters structure in the station_parameters structure (and remove the station_parameters fields already existing in link_station_parameters).

2022-07-15wifi: mac80211: fix mesh airtime link metric estimatingAditya Kumar Singh1-1/+6
ieee80211s_update_metric function uses sta_set_rate_info_tx function to get struct rate_info data from ieee80211_tx_rate struct, present in ieee80211_sta->deflink.tx_stats. However, drivers can skip tx rate calculation by setting rate idx as -1. Such drivers provides rate_info directly and hence ieee80211s metric is updated incorrectly since ieee80211_tx_rate has inconsistent data. Add fix to use rate_info directly if present instead of sta_set_rate_info_tx for updating ieee80211s metric.

2022-07-15wifi: mac80211: exclude multicast packets from AQL pending airtimeFelix Fietkau1-1/+1
In AP mode, multicast traffic is handled very differently from normal traffic, especially if at least one client is in powersave mode. This means that multicast packets can be buffered a lot longer than normal unicast packets, and can eat up the AQL budget very quickly because of the low data rate. Along with the recent change to maintain a global PHY AQL limit, this can lead to significant latency spikes for unicast traffic. Since queueing multicast to hardware is currently not constrained by AQL limits anyway, let's just exclude it from the AQL pending airtime calculation entirely.
