Comment (by dgoulet):
Status update:
asn and I have setup an environment to reproduce this `INTRODUCE2` DDoS
for which we were successful at reproducing the max CPU utilization on the
service. However, we haven't figured out just yet how can the service
still receives `INTRODUCE2` cells 30+ minutes after the circuit has been
closed (found from the logs given in private).
Ticket #30291 has been opened regarding a reason of the high CPU usage.
And nickm already worked on improvements so we expect these upstream soon.
We'll be working on the DoS master ticket #29999, especially #15516 and
#26294 in the coming weeks. Improvements will be coming to master
incrementally thus expect more updates about the situation as we progress
in this work.
