Hi,
man setsockopt(2) states that "passing in an optval of NULL will remove
the filter", however, setsockopt() always return EINVAL in this case,
because do_setopt_accept_filter() removes the filter if sopt == NULL, but
not if sopt->val == NULL. The fix is easy:
- if (sopt == NULL) {
+ if (sopt == NULL || sopt->val == NULL) {
By the way, is it easy to add timeout for dataready and httpready filters ?
Now the stale connections may live for long time.
