Donenfeld from comment #5) Indeed, I'm not really sure why we prohibit bind() if no addresses from the corresponding family are assigned. That behaviour appears to predate FreeB= SD even. It might be just a matter of removing the corresponding checks. OTO= H, it's perfectly valid to disable the use of either v4 or v6 in system (it's = even possible to compile corresponding support out of the kernel), and in that c= ase it seems rather odd to require that both sockets bind successfully. Is it possible to have wg_socket_bind() succeed if it's able to bind at least one= of the sockets, assuming that sobind() returns EADDRNOTAVAIL for the other? --=20 You are receiving this mail because: You are the assignee for the bug.=
