Hi, First off, everything described here is using mac80211_hwsim. I have not tested if any of this happens on physical hardware or not. Commit 01afc6fed seems to have changed the kernel behavior with regard to lost beacons. So much so that it completely breaks all roaming tests for IWD and (if kept this way) will require severe changes to the existing roaming logic we have used for quite a long time. Plus supporting older kernels AND this new behavior is going to be quite annoying to deal with. Before, the kernel would only send a lost beacon QCM event when it detected beacon loss. This allowed us to scan, find a suitable BSS to roam to, and then roam. Now it also sends Del Station, Deauthenticate, and Disconnect all immediately after a lost beacon, and the disconnect reason being DISASSOC_DUE_TO_INACTIVITY (4). We handle these extra events as we would at any other time, and fully disconnect which prevents us from being able to roam quickly (as well as breaking tests). Looking at that commit nothing particular jumps out at me, but obviously those added flags are causing something else to send these extra events. Was this change actually intended to cause these extra events? And if so, why was it changed? Thanks, James
