On the other hand, thinking about it: we only destroy the mutex after doing an if_detach + if_free, but is it the case (CC glebius@) that the ifnet isn't fully detached until an epoch elapses, so we very well could have some packets lingering and should defer-reclaim those last bits? For the other one: I don't really know how ocserv works, but I think I could see a massive oversight in that one might be able to destroy a tun device that's not yet fully constructed. -- You are receiving this mail because: You are on the CC list for the bug.
