OSX: Workaround CMSG_FIRSTHDR bug
On OSX, CMSG_FIRSTHDR will return a pointer into the control buffer
space when controllen == 0. We work around by testing for a non-zero
controllen before trying to parse control messages.
Test case:
int
main() {
struct msghdr msg;
msg.msg_control = &msg;
msg.msg_controllen = 0;
if (CMSG_FIRSTHDR(&msg))
printf("Bug found!\n");
}
