Description Adrian Chadd freebsd_committer freebsd_triage 2013-05-06 23:00:01 UTC
When a station reassociates, the crypto state (eg CCMP RSC/TSC counters) may not be reset "right".

How-To-Repeat: What I see:

* doing lots of UDP TX from FreeBSD STA -> FreeBSD AP;
* the station reassociates;
* .. lots of CCMP replay attack complaints on the AP side.

Adrian, did you ever fix this or is it still assumed an issue?
Comment 4 Adrian Chadd freebsd_committer freebsd_triage 2024-03-06 16:14:30 UTC
oh good question! want me to go re-test it against -HEAD?

I think this bug was partially due to some race and partially due to full TX queues. It should be easy to reproduce again with a variety of hardware!
