Hi,
HAProxy 2.3.19 was released on 2022/03/14. It added 14 new commits
after version 2.3.18.
All fixes included in this release were already described in the 2.4.14
announcement. Here is a cut-paste of relevant parts:
* An issue in the pass-through multiplexer leading to a connection leak on
the server side when timeout occurred during the connection
establishment. In this case, the server connection was detached from the
application stream but not closed. At this stage the connection could
only be closed by the server, if it was finally accepted, or by the
kernel, after all SYN retries. All versions as far as 2.3 are affected
by this bug.
* An issue in the master CLI. When a command was sent to a worker, the
errors, especially write errors, during the response processing were not
properly handled. The session could remain stuck if a client quickly
closed the connection before the response was fully sent. The maxconn
value of the master CLI is set 10. Thus, it could quickly be
unresponsive if this happened several times.
* An issue with all HTX applets. The end of a message was only reported at
the HTX level. The channel's flags were not updated accordingly. The
only known visible effect of this bug was some server aborts erroneously
reported in the stats counters.
* Proxy mode (tcp, http, cli...) is not properly reported when
displayed. Missing "syslog" and "peers" mode can now be reported.
* The anti-loop protection in process_stream() was improved to only count
the no-progress calls.
Thanks everyone for your help and your contributions!
