This always was most productive way for us. I've been doing extremely limited testing on the sockopt.c patch, on a 7.0R box that used to have problems, and it "seems to" work. However, the failures we were noticing seemed most frequent and catastrophic when using a 7.0R box as a router with about a dozen interfaces active (we got instant failures, in many/most/all?? cases). I don't have a lab setup capable of reproducing this at the moment, and am not willing to sacrifice production networks to the "well just try it and see" patch testing god. I believe the question that was asked is not the question you answered. I, too, would like someone who can offer a knowledgeable opinion as to the correctness of the patch. Were someone who has worked on the code, such as Bruce, to tell me that it appeared to be the right solution, I would be willing to risk a test on a 7.0R box known to fall over rapidly with the multicast issue. I am certainly interested in seeing this fixed. Until someone can either test the heck out of this, or offer a definitive opinion of the correctness based on experience with this subsystem, it would seem premature to ask the port maintainer to include a patch of dubious correctness. I have cc:'d bms@ in the hopes of bringing in such an opinion. I am not sure who else is working on the multicast subsystem at this time, but hopefully someone else can input if appropriate. Knowing that the patch was correct would also provide some leverage for those of us with interest in this code to persuade the Quagga developers to do something about this. As it is, we're left here holding a bag of "this patch is supposed to work but we don't really know it is correct." So it would be really useful to have such an opinion. Thanks, ...
