This replacement is a little menial, but it explicitly catches all the places where we allow a local socket. The actual implementation of opening a AF_UNIX socket is almost hidden in the patch. The detection of "valid address" is now more complex: p->addr.itype != ADDR_INTERNAL_WIREADDR || p->addr.u.wireaddr.type != ADDR_TYPE_PADDING But most places we do this, we should audit: I'm pretty sure we can't get an invalid address any more from gossipd (they may be in db, but we should fix that too). Closes: #1323 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
