Well, I'm now trying to educate myself on the send part. It's still not very clear to me and I'd like to understand a little bit better why we have this corruption problem and why there is a difference between sending segments from memory and sending them from another socket where they were already waiting.
printks are the best choice, since you will get exactly what you are looking for instead of deciphering what developer or code told you.
I think I'll put printks everywhere and see what I can observe. Knowing about the GSO/SG workaround already helps me enable/disable the bug.
I wish I could also be capable to disable the bugs... :) -- Evgeniy Polyakov
