I find this lines. But I cannot find accf's mean. can you explain to me?thank
you very much!
if ((so->so_options & SO_ACCEPTFILTER) == 0) {
...
} else {
ACCEPT_UNLOCK();
SOCK_LOCK(so);
so->so_upcall =
head->so_accf->so_accept_filter->accf_callback;
so->so_upcallarg = head->so_accf->so_accept_filter_arg;
so->so_rcv.sb_flags |= SB_UPCALL;
so->so_options &= ~SO_ACCEPTFILTER;
SOCK_UNLOCK(so);
so->so_upcall(so, so->so_upcallarg, M_DONTWAIT);
}
