Hi, Yesterday I found the bug fixed by this commit: https://git.kernel.org/cgit/linux/kernel/git/jberg/mac80211.git/commit/?id=e6436be21e77e3659b4ff7e357ab5a8342d132d2
The first case can easily be reproduced by running: # iw wlan0 interface add wlan0 type monitor (reusing the name "wlan0" twice, the command should fail) I tried to see what happens with kmemleak, but for some reason it won't report it even with forced rescan etc. Am I missing something? Thanks, johannes
