Hi, HAProxy 2.7.6 was released on 2023/03/28. It added 39 new commits after version 2.7.5.
Here is a short summary of the improvements : Aurélien has extended the internal listener API to better handle the resume operation. One noticeable effect is that listeners that have an ABNS abstract namespace socket can now support reload without crashing haproxy. Also, it also ensures properly that 'no-quic' configuration keyword is respected on reload so that disabled QUIC listeners are not started. 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. As usual, several QUIC improvements were introduced. 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/2.7/src/ Git repository : https://git.haproxy.org/git/haproxy-2.7.git/ Git Web browsing : https://git.haproxy.org/?p=haproxy-2.7.git Changelog : https://www.haproxy.org/download/2.7/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 (13): BUG/MINOR: quic: wake up MUX on probing only for 01RTT BUG/MINOR: quic: ignore congestion window on probing for MUX wakeup BUG/MINOR: trace: fix hardcoded level for TRACE_PRINTF BUG/MEDIUM: mux-quic: release data from conn flow-control on qcs reset MINOR: mux-quic: complete traces for qcs emission MINOR: mux-quic: adjust trace level for MAX_DATA/MAX_STREAM_DATA recv MINOR: mux-quic: add flow-control info to minimal trace level BUG/MINOR: h3: properly handle incomplete remote uni stream type BUG/MINOR: mux-quic: prevent CC status to be erased by shutdown MINOR: mux-quic: interrupt qcc_recv*() operations if CC scheduled MINOR: mux-quic: ensure CONNECTION_CLOSE is scheduled once per conn MINOR: mux-quic: close on qcs allocation failure MINOR: mux-quic: close on frame alloc failure Aurelien DARRAGON (14): MINOR: proto_uxst: add resume method MINOR: listener/api: add lli hint to listener functions MINOR: listener: add relax_listener() function MINOR: listener: workaround for closing a tiny race between resume_listener() and stopping MINOR: listener: make sure we don't pause/resume bypassed listeners BUG/MEDIUM: listener: fix pause_listener() suspend return value handling BUG/MINOR: listener: fix resume_listener() resume return value handling BUG/MEDIUM: resume from LI_ASSIGNED in default_resume_listener() MINOR: listener: pause_listener() becomes suspend_listener() BUG/MEDIUM: listener/proxy: fix listeners notify for proxy resume MEDIUM: proto_ux: properly suspend named UNIX listeners MINOR: proto_ux: ability to dump ABNS names in error messages 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 (3): MINOR: quic: Stop stressing the acknowledgments process (RX ACK frames) BUG/MINOR: quic: Dysfunctional 01RTT packet number space probing BUG/MINOR: quic: Missing STREAM frame type updated Willy Tarreau (7): 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 ---
