"reuseAddr" argument of BDatagramSocket::Bind is ignored

[jeremy-list]

When the following code is run, the string "Address already in use" is printed to the standard output, which is inappropriate because the reuseAddr argument is true on both binds.

	BDatagramSocket socket;
	BDatagramSocket socket2;
	BNetworkAddress address;
	status_t status;
	address.SetToWildcard(AF_INET, 8008);
	if ((status = socket.Bind(address, true)) != B_OK)
	  std::cout << strerror(status) << std::endl;
	if ((status = socket.SetBroadcast(true)) != B_OK)
	  std::cout << strerror(status) << std::endl;
	if ((status = socket2.Bind(address, true)) != B_OK)
	  std::cout << strerror(status) << std::endl;
	if ((status = socket2.SetBroadcast(true)) != B_OK)
	  std::cout << strerror(status) << std::endl;

This is something of an obstacle to local testing of software for Haiku that uses UDP broadcast packets.

It appears SO_REUSEPORT may also be needed?

Yes you're right. It's a little unfortunate that this can't be done directly on the BDatagramSocket but working around that limitation isn't too difficult. I believe this ticket can be closed.
