Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

bonding: Improve IGMP join processing In active-backup mode, the current bonding code duplicates IGMP traffic to all slaves, so that switches are up to date in case of a failover from an active to a backup interface. If bonding then fails back to the original active interface, it is likely that the "active slave" switch's IGMP forwarding for the port will be out of date until some event occurs to refresh the switch (e.g., a membership query). This patch alters the behavior of bonding to no longer flood IGMP to all ports, and to issue IGMP JOINs to the newly active port at the time of a failover. This insures that switches are kept up to date for all cases. "GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally reported this problem, and included a patch. His original patch was modified by Jay Vosburgh to additionally remove the existing IGMP flood behavior, use RCU, streamline code paths, fix trailing white space, and adjust for style.
