About Pacemaker
Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.
Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.
