[FR] fragment order #79

Open mirabilos opened 2 years ago

mirabilos commented 2 years ago

It would be great if the tools had switches for ordering the fragments, if fragmentation is enabled. I need to test both “first fragment is received first” and “nōn-first fragment is received first” in the kernel changes I’m working on.

Good point. I will implement this. -- WIll get back to you shortly.

Thank you!

Is it just fine to e.g. allow reverse order, or would you need more granularity such as specifying the order as in "Frag #3, Frag #1, Frag #2"?

2"?

For me, reverse order would suffice. I’m adding diagnostics to a qdisc LKM, and there’s desire to tag TCP/UDP traffic with IPs and ports, so I need to be able to test fragment info caching.
