This bug arrvived with this commit:
MINOR: quic: centralize padding for HP sampling on packet building
What was missed is the fact that at the centralization point for the
PADDING frame to add for too short packet, <len> payload length already includes
<*pn_len> the packet number field length value.
So when computing the length of the PADDING frame, the packet field length must
not be considered and added to the payload length (<len>).
This bug leaded too short PADDING frame to too short packets. This was the case,
most of times with Application level packets with a 1-byte packet number field
followed by a 1-byte PING frame. A 1-byte PADDING frame was added in this case
in place of a correct 2-bytes PADDINF frame. The header packet protection of
such packet could not be removed by the clients as for instance for ngtcp2 with
such traces:
I00001828 0x5a135c81e803f092c74bac64a85513b657 pkt could not decrypt packet number
As the header protection could no be removed, the header keyupdate bit could also
not be read by packet analyzers such as pyshark used during the keyupdate tests.
No need to backport.

HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
- doc/management.txt for the management guide
- doc/regression-testing.txt for how to use the regression testing suite
- doc/peers.txt for the peers protocol reference
