Yes, it's the red parts that interest me. Intermixing those with various wireguard-specific netlink calls and setting devices up and down and putting traffic through those sockets, in weird ways, could dig up bugs. > I think theoretically these parts should be reachable too because > syzkaller can do unshare and obtain net ns fd's. > > It's quite hard to test because it just crashes all the time on known bugs. > So maybe the most profitable way to get more coverage throughout the > networking subsystem now is to fix the top layer of crashers ;) Ahhh, interesting, so the issue is that syzkaller is finding too many other networking stack bugs before it gets to being able to play with wireguard.
