We contemplated this back in early 2023and didn't do it yet, but nobody stepped up to maintainit.It's already _mostly_ dead code since it can really onlybe used for AP and maybe IBSS and monitor, but not on aclient since there's no way to scan (and hasn't been ina very long time, if ever), so the only thing that evercould really happen with it was run syzbot and trip overassumptions in the code.Signed-off-by: Johannes Berg Reviewed-by: Lachlan Hodges Link: https://patch.msgid.link/20260529084502.080c5885f0b7.I77cc94485b523c3c006005b9233db13cd4e077b3@changeidSigned-off-by: Johannes Berg List of files: /linux/drivers/net/wireless/virtual/mac80211_hwsim_main.c

Wed, 06 May 2026 05:44:24 +0200

wifi: mac80211_hwsim: implement NAN synchronizationAdd all the handling to do NAN synchronization on 2.4 GHz includingsending out beacons. With this, the mac80211_hwsim NAN device also workswhen used in conjunction with an external medium simulation.Note that the TSF sync is not ideal in case of an external mediumsimulation. This is because the mactime for received frames needs to beestimated and the simulation may not update the timestamp of beaconsto the actual time that the frame was transmitted.The implementation has an initial short phase where it scans forclusters. This facilitates cluster joining and avoids creating a newcluster immediately, which would result in two cluster joinnotifications. It does not scan otherwise and will only see anothercluster appearing if a discovery beacon happens to be sent during the2.4 GHz discovery window (DW).Signed-off-by: Benjamin Berg Signed-off-by: Miri Korenblit Link: https://patch.msgid.link/20260506064301.7d21c3cdc565.I98b6c15eadefd6d123658294ef1a0cd3c2ce3054@changeidSigned-off-by: Johannes Berg List of files: /linux/drivers/net/wireless/virtual/mac80211_hwsim_main.c
