| |
Hi,
This is a release announcement for the LTTng Linux kernel tracer 2.12.7 and 2.13.1 releases. Both are bug fix releases in the lttng-modules stable branches. They also enable support for the most recent Linux kernel releases.
LTTng-modules 2.12.7 contains instrumentation fixes for the 5.14, 5.15 and 5.16-rc Linux kernels. Kernel version ranges were adjusted for instrumentation of the RHEL 8.4 kernel.
LTTng-modules 2.13.1 fixes scenarios where trigger actions are missing:
There is an issue when associating multiple actions to a single system call, where the first action is effectively added, but the following actions are silently ignored.
The affected on-event trigger is a feature newly introduced in 2.13.
This 2.13.1 release also contains instrumentation fixes for the 5.15 and 5.16-rc Linux kernels. It now emits a warning in the kernel console whenever registration of events internally fails within LTTng-modules, for example in case of out-of-memory error.
As always, feedback is welcome!
Thanks,
Mathieu
