(usagi-users 01088) after IETF

[Parijat Mishra <parijat@xxxxxxxxxxxxxx>]

Hey there, USAGI team!

It was nice meeting you all at the IETF.  Now that I have got the jet-lag 
under control, I am going back to work now :-)  Hope you all are doing fine.


Ummm..., talking about work, what happened to the multicast problem I 
described on the mailing-list?  To refresh everyone's memory, I observed that 
when two (or more) processes try to bind() to the same multicast address/port 
combination on a host, the second bind() fails with an "address already in 
use" error.  This should be normal for unicasr addresses, but should be 
allowed for multicast addresses.  This problem occurs only with the USAGI 
kernels, both for IPv4 and IPv6 multicast addresses.  The bind()s succeed on 
the normal Linux kernels. I have only tested this on the 2.4 kernels, since I 
do not use the 2.2 kernels.  Because of this problem, we cannot deploy the 
few popular multimedia applications available for Linux that are IPv6 enabled 
(RAT -- Robust Audio Tool, and VIC, etc.) on the USAGI kernels.  Did anyone 
else observe this?  Any solutions?
