Log message:
bgpd has been naughty. It tries to play with AF_UNIX sockets without
pledging "unix".
Move control_listen up to the main process which already has
pledge("unix"). accept(2) was already allowed.

You can listen, getpeername, getsockname, and of course set/getsockopt is somewhat available.. yes, this makes pledge the anti-capsicum, kind of like salt from Secovlje.. reasoning due to a conversation with tedu
