Hi, HAProxy 2.6.12 was released on 2023/03/28. It added 19 new commits after version 2.6.11.
Here is a detailled summary of the improvements : In 2.6.10, important fixes were introduced on FD thread concurrent access which could have caused a crash. However, this patch was incomplete for kqueue and events ports pollers used respectively in BSD and SunOS. This has been corrected by Willy for the current release. Christopher fixed an issue affecting the H1 multiplexer. If the reponse was fully transferred before the whole request is read, there was a risk that the channel is left open without any further processing. In the end, this caused the stream to enter a spinning loop which triggered an assertion failure crash. A similar problem was also encountered for the stats applet when large GET HTTP requests were issued to it. The stream is left in a blocked state with memory resource consumed for nothing. A bunch of QUIC fixes were made. Two github issues were opened recently about an assertion failure on the sending code after several hours of running. A serie of patches were deployed to solve them, with notably a fix on the connection level flow-control calculation. Also, probing on PTO expiration has been corrected which should improve transfers under packet loss condition. Finally, if a connection is preemptively closed by haproxy for any reason the CONNECTION_CLOSE error code should be more precise. Willy has fixed several crashes and leaks related to potential memory allocation failures. The code is now more robust and should better resist under memory pressure. Thanks to everyone who contributed to this release. ############################################################################################# Please find the usual URLs below : Site index : https://www.haproxy.org/ Documentation : https://docs.haproxy.org/ Wiki : https://github.com/haproxy/wiki/wiki Discourse : https://discourse.haproxy.org/ Slack channel : https://slack.haproxy.org/ Issue tracker : https://github.com/haproxy/haproxy/issues Sources : https://www.haproxy.org/download/2.6/src/ Git repository : https://git.haproxy.org/git/haproxy-2.6.git/ Git Web browsing : https://git.haproxy.org/?p=haproxy-2.6.git Changelog : https://www.haproxy.org/download/2.6/src/CHANGELOG Dataplane API : https://github.com/haproxytech/dataplaneapi/releases/latest Pending bugs : https://www.haproxy.org/l/pending-bugs Reviewed bugs : https://www.haproxy.org/l/reviewed-bugs Code reports : https://www.haproxy.org/l/code-reports Latest builds : https://www.haproxy.org/l/dev-packages --- Complete changelog : Amaury Denoyelle (5): BUG/MINOR: quic: wake up MUX on probing only for 01RTT BUG/MINOR: trace: fix hardcoded level for TRACE_PRINTF BUG/MEDIUM: mux-quic: release data from conn flow-control on qcs reset BUG/MINOR: h3: properly handle incomplete remote uni stream type BUG/MINOR: mux-quic: prevent CC status to be erased by shutdown Aurelien DARRAGON (2): DOC: config: set-var() dconv rendering issues BUG/MINOR: applet/new: fix sedesc freeing logic Christopher Faulet (2): BUG/MEDIUM: stats: Consume the request except when parsing the POST payload BUG/MEDIUM: mux-h1: Wakeup H1C on shutw if there is no I/O subscription Frédéric Lécaille (1): BUG/MINOR: quic: Missing STREAM frame type updated Willy Tarreau (9): BUG/MAJOR: poller: drop FD's tgid when masks don't match OPTIM: mux-h1: limit first read size to avoid wrapping BUG/MEDIUM: stream: do not try to free a failed stream-conn BUG/MEDIUM: mux-h2: do not try to free an unallocated h2s->sd BUG/MEDIUM: mux-h2: erase h2c->wait_event.tasklet on error path BUG/MEDIUM: stconn: don't set the type before allocation succeeds BUG/MINOR: stconn: fix sedesc memory leak on stream allocation failure BUG/MEDIUM: mux-h1: properly destroy a partially allocated h1s BUG/MEDIUM: applet: only set appctx->sedesc on successful allocation --- -- Amaury Denoyelle
