The local udp socket has some #warning , for example:
```
#ifdef CONFIG_NET_LOCAL_DGRAM
int local_release_halfduplex(FAR struct local_conn_s *conn)
{
#if 1
/* REVISIT: We need to think about this carefully. Unlike the connection-
* oriented Unix domain socket, we don't really know the best time to
* release the FIFO resource. It would be extremely inefficient to create
* and destroy the FIFO on each packet. But, on the other hand, failing
* to destroy the FIFO will leave the FIFO resources in place after the
* communications have completed.
*
* I am thinking that there should be something like a timer. The timer
* would be started at the completion of each transfer and cancelled at
* the beginning of each transfer. If the timer expires, then the FIFO
* would be destroyed.
*/
# warning Missing logic
return OK;
#else
char path[LOCAL_FULLPATH_LEN];
/* Destroy the half duplex FIFO if it exists. */
local_hd_name(conn->lc_path, path);
return local_release_fifo(path);
#endif
}
#endif /* CONFIG_NET_LOCAL_DGRAM */
```
I guess no one used it before? Anyway, I fixed the potential bug.
