Package: haproxy
Version: 2.2.8-1~bpo10+1

All released versions of haproxy 2.2 contain a nasty bug which will continue to override the backend server status as UP, when the agent-check returns UP, although the http-check reports the backend as down.

The issue was fixed upstream[1] and we would like to request the fix to be released with the Debian backports version, as this may cause unexpected outages.


Best, Stefan.

I have uploaded 2.2.9 to backports, but from my understanding, this is
not enough. I'll put the patch on top of 2.2.9.

Hello!

Thanks for the fix! Is the updated version going to transition to buster-backports at some point?

Best, Stefan

Hi Vincent!

Thanks a lot for your help!

I can still only see 2.2.9-1 in backports. Can you just let me know when we could expect 2.2.9-2 to be released with back ports?

Best, Stefan.

It's in the queue:

https://ftp-master.debian.org/backports-new.html

As it is the first non stretch-backports, I think it will be processed
soon.
