Module name:	xorp
Repository:	xorp/libcomm/
Changes by:	pavlin@xorpc.icir.org.	04/01/26 17:13:06

Modified files:
	xorp/libcomm/: comm_api.h comm_user.c 

Log message:
	* Change the behavior of comm_bind_join_udp4 and comm_bind_join_udp6:
	
	Now we bind the socket to ANY address instead of the multicast address
	only. If we bind to the multicast address instead, then using
	the same socket for sending multicast packets will trigger a bug
	in the FreeBSD kernel: the source IP address will be set to the
	multicast address. Hence, the application itself may want to filter
	the UDP unicast packets that may have arrived with a destination address
	one of the local interface addresses and the same port number.
	[A problem found by Orion]
	
	* Adjust the kdoc comments to reflect the above change.
