This fix follows this previous one:
BUG/MINOR: quic: reorder fragmented RX CRYPTO frames by their offsets
which is not sufficient when a client fragments and mixes its CRYPTO frames AND
leaveswith holes by packets. ngtcp2 (and perhaps chrome) splits theire CRYPTO
frames but without hole by packet. In such a case, the CRYPTO parsing leads to
QUIC_RX_RET_FRM_AGAIN errors which cannot be fixed when the peer resends its packets.
Indeed, even if the peer resends its frames in a different order, this does not
help because since the previous commit, the CRYPTO frames are ordered on haproxy side.
This issue was detected thanks to the interopt tests with quic-go as client. This
client fragments its CRYPTO frames, mixes them, and generate holes, and most of
the times with the retry test.
To fix this, when a QUIC_RX_RET_FRM_AGAIN error is encountered, the CRYPTO frames
parsing is not stop. This leaves chances to the next CRYPTO frames to be parsed.
Must be backported as far as 2.6 as the commit mentioned above.
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.

- 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
