Can you post the *hex* version of the packet? The "VSA too short" error means that it isn't printing out what's actually in the packet. So... it doesn't say *why* the VSA is too short.
I'm not sure either, I attached the whole packet in hex for your review.
And does this crash when the server *doesn't* have that patch?
It doesn't crash when I omit the patch. My C is very weak so I suspect I did something wrong, but I really need this feature, so muddled though it anyway. While trying to troubleshoot I was able to capture the packet that crashes it. There are more packets like it from the same host that show the same VSA too short that also crash it.
Without the *contents* of the attribute, it's impossible to know more.
