Hi, This is a stable release announcement for the LTTng kernel tracer, a kernel tracer for the Linux kernel. The most relevant news about this release is added support for the Linux kernel v6.13 and for the RHEL 9.5 kernels by LTTng-modules v2.13.17. We are aware that this release of LTTng-modules fails to build against sles15sp5 and Linux v6.13 on powerpc32 in our CI. We will investigate and fix these in a future release, but we aim to release promptly after Linux v6.13, so considering that LTTng-modules 2.13.x has never successfully built against those kernels, those are not considered release blockers. Detailed change log: 2025-01-24 (Global Belly Laugh Day) LTTng modules 2.13.17 * fix: include linux/fs.h for 'struct file' definition (v4.5) * fix: add missing check for __must_check 'lttng_file_ref_put()' (v6.13) * Fix: uprobe consumer handler signature changed in Linux 6.13.0-rc1 * Fix: lookup_fdget_rcu removed in Linux 6.13.0-rc1 * Fix: f_count replaced with f_ref in Linux 6.13.0-rc1 * Fix: sched_stat_runtime changed in Linux 6.6.66 * lttng-modules fix for RHEL 9.5 kernels Thanks, Mathieu Project website: https://lttng.org Documentation: https://lttng.org/docs Download link: https://lttng.org/download -- Mathieu Desnoyers EfficiOS Inc. https://www.efficios.com
