Hi,
HAProxy 2.4.21 was released on 2023/01/27. It added 43 new commits
after version 2.4.20.
As for the 2.6.8 and the 2.5.11, this release includes the fix about the
"set-uri" HTTP action. This fix was delayed for the 2.4.20. It is now
shipped with the 2.4.21. The behavior of this action is no longer the
same. This action is been bogus for a while and was not working as
documented, and used to make HTTP/1 and HTTP/2 produce different
outputs. The URI is now sent to H1 server exactly as set by the action.
Otherwise, for other fixes:
About the H2:
* Interim responses that carry the end-of-stream flag are now rejected as
invalid while it was handled as a full response. The consequences of
this issue are uncertain in 2.4 and newer, but on 2.2 and older it could
trigger a BUG_ON() condition and cause a panic.
About the FCGI
* The path-info subexpression was not properly handled due to an inverted
condition.
* A major fix regarding uninitialized bytes in the FCGI mux was backported.
It one could have leak sensitive data to the backends before the fix.
About listeners:
* Multiple races were found and addressed related to closed FDs (mostly
happening on reload, sometimes on resuming after an aborted reload)
About HTTP rules:
* Make sure that the logged status matches the reported status even upon
errors and also after http-after-response
* There was a parsing error reported for responses carrying a websocket
header when the status was not 101.
About the Master-Worker:
* When trying to upgrade from a previous version with a reload instead of
a restart, a bug in the master-worker was preventing to reload and was
stopping the whole process.
About other fixes:
* A fix for a buffer realignment bug introduced in 1.9 was fixed. It's
uncertain whether it was possible to trigger it or not, but it could
possibly have been responsible for some rare unexplained corruptions.
* The haproxy_backend_agg_check_status metric for the Prometheus exporter
was backported.
* A scheduling issue in the resolvers was preventing the resolution during
runtime.
Thanks everyone for you help and your contributions !
