2024-02-02wifi: mac80211: clean up FILS discovery change flags handlingJohannes Berg
It doesn't make sense to return BSS change flags in an int, as they're a bigger type. For this particular function it still works OK, but clean it up to avoid future errors (or copying this code in a broken way.)

2024-01-26wifi: mac80211: apply duration for SW scanMichael-CY Lee
This patch makes duration in scan request be applicable when using SW scan, but only accepts durations greater than the default value for the following reasons: 1. Most APs have a beacoon interval of 100ms. 2. Sending and receiving probe require some delay. 3. Setting channel to HW also requires some delays Signed-off-by: Michael-CY Lee <michael-cy.lee@mediatek.com> Link: https://msgid.link/20240123054752.22833-1-michael-cy.lee@mediatek.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2023-12-21wifi: mac80211: add a driver callback to check active_linksMiri Korenblit
During ieee80211_set_active_links() we do (among the others): 1. Call drv_change_vif_links() with both old_active and new_active 2. Unassign the chanctx for the removed link(s) (if any) 3. Assign chanctx to the added link(s) (if any) 4. Call drv_change_vif_links() with the new_active links bitmap The problem here is that during step #1 the driver doesn't know whether we will activate multiple links simultaneously or are just doing a link switch, so it can't check there if multiple links are supported/enabled. (Some of the drivers might enable/disable this option dynamically) And during step #3, in which the driver already knows that, returning an error code (for example when multiple links are not supported or disabled), will cause a warning, and we will still complete the transition to the new_active links. (It is hard to undo things in that stage, since we released channels etc.) Therefore add a driver callback to check if the desired new_active links will be supported by the driver or not. This callback will be called in the beginning of ieee80211_set_active_links() so we won't do anything before we are sure it is supported.

2023-12-21wifi: mac80211: Skip association timeout update after comeback rejectionJouni Malinen
It is possible for the TX status report for the (Re)Association Request frame to be delayed long enough for the AP's (Re)Association Response frame to be received and processed before it. If that were to happen for a case where the AP rejects the association with indication to come back later, the association timeout and retry state should not be modified anymore with the TX status information that would be processed after this. Updating the association timeout in such a reverse order of events could result in shortening the timeouts for the association comeback mechanism and that could result in the association failing. Track whether we have already processed association rejection with comeback time and if so, skip the timeout and retry update on any following TX status report.
