SSM, IGMPv3 on Linux

By "working", you may mean one of two things:

1. SSM support for end-hosts
  
  Sprint labs has a IGMPv3 patch available for kernel 2.4.0, and 2.2.18 at:
  
  http://www.sprintlabs.com/Department/IP-Interworking/multicast/linux-igmpv3/
  
  I had to make some minor modifications to the patch for my 2.4.2 kernel.  
  When you have your kernel patched, you simply use the new API discussed in
  
  draft-ietf-idmr-msf-api-01.txt  (try google)
  
2. Using Linux as a SSM router

 I've been using PIM-SM with application-layer source filters to do testing.  
 I am not aware of a SSM-specific mrouted for linux yet, but the changes 
 which need to be made to PIM-SM to realize the SSM model are fairly simple.  
 For specifics, see:
  
  http://www.dante.net/mbone/refs/draft-bhattach-diot-pimso-00.txt
  
  Basically the PIM-SM router needs to be able to skip the shared tree 
  and RP and go straight to source-specific trees, depending on which 
  type of IGMPv3 join was received.

I don't believe IGMPv3 is a standard part of linux yet, unfortunately.  Does 
anyone know what version this is going to be officially included in?

Thanks,
