Hi Paul, Searching for af_netrom across other syzbot bugs: https://groups.google.com/forum/#!searchin/syzkaller-bugs/af_netrom%7Csort:date I see at least: https://syzkaller.appspot.com/bug?extid=b0b1952f5864b4009b09 https://syzkaller.appspot.com/bug?extid=febf3c50d4262e578b1c https://syzkaller.appspot.com/bug?extid=defa700d16f1bd1b9a05 Which suggests there are some serious lifetime problems in netrom sockets. That would probably explain this crash as well.
This is supposed to be fixed by: https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=63346650c1a94a92be61a57416ac88c0a47c4327 Please let me know if it isn't. Thanks.
