v01d opened a new issue #3374:
URL: https://github.com/apache/incubator-nuttx/issues/3374
```
Description: The logic in udp_input() expects either a single receive
socket or
none at all. However, multiple sockets should be capable of
receiving a UDP datagram (multicast reception). This could be
handled easily by something like:
for (conn = NULL; conn = udp_active (pbuf, conn); )
If the callback logic that receives a packet responds with an
outgoing packet, then it will over-write the received buffer,
however. recvfrom() will not do that, however. We would have
to make that the rule: Recipients of a UDP packet must treat
the packet as read-only.
Status: Open
Priority: Low, unless your logic depends on that behavior.
