wifi: mac80211: add macros to loop over active links

2022-07-22T12:28:47Z

Add a preliminary version which will be updated later to loop over vif's and sta's active links. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: optionally implement MLO multicast TX

2022-07-22T12:28:36Z

For drivers using software encryption for multicast TX, such as mac80211_hwsim, mac80211 needs to duplicate the multicast frames on each link, if MLO is enabled. Do this, but don't just make it dependent on the key but provide a separate flag for drivers to opt out of this. This is not very efficient, I expect that drivers will do it in firmware/hardware or at least with DMA engine assistence, so this is mostly for hwsim. To make this work, also implement the SNS11 sequence number space that an AP MLD shall have, and modify the API to the __ieee80211_subif_start_xmit() function to always require the link ID bits to be set.

wifi: mac80211: expand ieee80211_mgmt_tx() for MLO

2022-07-22T12:28:35Z

There are a couple of new things that should be possible with MLO: * selecting the link to transmit to a station by link ID, which a previous patch added to the nl80211 API * selecting the link by frequency, similarly * allowing transmittion to an MLD without specifying any channel or link ID, with MLD addresses Enable these use cases. Also fix the address comparison in client mode to use the AP (MLD) address. Signed-off-by: Johannes Berg

wifi: mac80211: add hardware timestamps for RX and TX

2022-07-22T12:28:29Z

When the low level driver reports hardware timestamps for frame TX status or frame RX, pass the timestamps to cfg80211. Signed-off-by: Avraham Stern Signed-off-by: Johannes Berg

wifi: mac80211: select link when transmitting to non-MLO stations

2022-07-15T09:43:23Z

When an MLO AP is transmitting to a non-MLO station, addr2 should be set to a link address. This should be done before the frame is encrypted as otherwise aad verification would fail. In case of software encryption this can't be left for the device to handle, and should be done by mac80211 when building the frame hdr.

wifi: mac80211: remove link_id parameter from link_info_changed()

2022-07-15T09:43:20Z

Since struct ieee80211_bss_conf already contains link_id, passing link_id is not necessary. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: replace link_id with link_conf in switch/(un)assign_vif_chanctx()

2022-07-15T09:43:20Z

Since mac80211 already has a protected pointer to link_conf, pass it to the driver to avoid additional RCU locking. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: replace link_id with link_conf in start/stop_ap()

2022-07-15T09:43:17Z

When calling start/stop_ap(), mac80211 already has a protected link_conf pointer. Pass it to the driver, so it shouldn't handle RCU protection. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: mlme: track AP (MLD) address separately

2022-07-15T09:43:16Z

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

wifi: mac80211: change QoS settings API to take link into account

2022-07-15T09:43:15Z

Take the link into account in the QoS settings (EDCA parameters) APIs. Signed-off-by: Johannes Berg
