Curl 8.9.0 causes 100% cpu use #1289

Closed CountMurphy closed 2 months ago

CountMurphy commented 2 months ago

Running rtorrent on Arch. After updating curl to 8.9.0, rtorrent uses 100% cpu. Downgrading back to 8.8.0 fixes the issue.

Might be related to https://github.com/curl/curl/issues/14280 as the symptoms sound similar.

I noticed this too, running lsof -i I noticed the tracker connection is stuck in CLOSE_WAIT. This isn't happening with all trackers, but it's happening with ubuntu ones. https://releases.ubuntu.com/22.04/ubuntu-22.04.4-desktop-amd64.iso.torrent this torrent specifically I can re-create the issue with. Looking at Tracker list, the "https://torrent.ubuntu.com/announce" one is bolded.

The patch to resolve https://github.com/curl/curl/issues/14280 appears to resolve my issue. (It doesn't apply completely cleanly to 8.9.0, but fuzzing seems to get it to)

Fixed in 8.9.1.

Fixed in 8.9.1.

Can confirm as well.

CountMurphy commented 2 months ago

8.9.1 hasn't made it to the arch repos yet, but I'll close the ticket as fixed.
