I've been working on the volunteer project described here
https://www.torproject.org/getinvolved/volunteer.html.en#useMoreCores but can't spend much more time on it.
Right now, I have refactored circuit_receive_relay_cell() in relay.c (which calls relay_crypt() and eventually the AES crypt routines) to use the workqueue.c infrastructure similar to cpuworker.c.
When the refactored code runs in single threaded mode, all seems good. Once I activate the thread pool and start sending it work with threadpool_queue_work(), it Bootstraps 100% okay and runs for several minutes before crashing on cells it doesn't handle properly.
I'm happy to share my code with anyone interested.
Hi Jeremy!
This is great! Thanks for this. You should definitely post your code (link to branch or .diff) to ticket #7572 [1] so someone at some point can take a look at it and help you out.
Thanks! David
Thank you. I have posted my code and tried to explain my thought process on ticket #7572.
