wifi: mac80211: do not pass AP_VLAN vif pointer to drivers during flush

2023-11-24T17:28:29+00:00

This fixes WARN_ONs when using AP_VLANs after station removal. The flush call passed AP_VLAN vif to driver, but because these vifs are virtual and not registered with drivers, we need to translate to the correct AP vif first.

wifi: mac80211: add link id to mgd_prepare_tx()

2023-10-23T09:47:40+00:00

As we are moving to MLO and links terms, also the airtime protection will be done for a link rather than for a vif. Thus, some drivers will need to know for which link to protect airtime. Add link id as a parameter to the mgd_prepare_tx() callback.

wifi: mac80211: make mgd_protect_tdls_discover MLO-aware

2023-10-23T09:45:17+00:00

Since userspace can choose now what link to establish the TDLS on, we should know on what channel to do session protection. Add a link id parameter to this callback.

wifi: mac80211: add a driver callback to add vif debugfs

2023-10-23T09:43:26+00:00

Add a callback which the driver can use to add the vif debugfs. We used to have this back until commit d260ff12e776 ("mac80211: remove vif debugfs driver callbacks") where we thought that it will be easier to just add them during interface add/remove. However, now with multi-link, we want to have proper debugfs for drivers for multi-link where some files might be in the netdev for non-MLO connections, and in the links for MLO ones, so we need to do some reconstruction when switching the mode. Moving to this new call enables that and MLO drivers will have to use it for proper debugfs operation.

wifi: mac80211: add support for mld in ieee80211_chswitch_done

2023-09-11T10:31:31+00:00

This allows to finalize the CSA per link. In case the switch didn't work, tear down the MLD connection. Also pass the ieee80211_bss_conf to post_channel_switch to let the driver know which link completed the switch.

wifi: cfg80211: remove wdev mutex

2023-09-11T09:27:23+00:00

Since we're now protecting everything with the wiphy mutex (and were really using it for almost everything before), there's no longer any real reason to have a separate wdev mutex. It may feel better, but really has no value. Signed-off-by: Johannes Berg

wifi: mac80211: check wiphy mutex in ops

2023-09-11T09:27:21+00:00

Check that we hold the wiphy mutex in the ops when calling the driver, since we're now on our way to always hold it, and simplify the locking. Reviewed-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

wifi: mac80211: add more ops assertions

wifi: mac80211: stop warning after reconfig failures

2023-06-06T12:17:21+00:00

If we have a reconfig failure in the driver, then we need to shut down the network interface(s) at the network stack level through cfg80211, which can result in a lot of those "Failed check-sdata-in-driver check, ..." warnings, since interfaces are considered to not be in the driver when the reconfiguration fails, but we still need to go through all the shutdown flow. Avoid many of these warnings by storing the fact that the stack experienced a reconfiguration failure and not doing the warning in that case.

wifi: mac80211: add flush_sta method

2023-04-13T14:32:31+00:00

Some drivers like iwlwifi might have per-STA queues, so we may want to flush/drop just those queues rather than all when removing a station. Add a separate method for that. Signed-off-by: Johannes Berg
