Subject: [RELEASE] LTTng-modules 2.12.7 and 2.13.1 (Linux kernel tracer)
Date: Wed, 5 Jan 2022 14:11:56 -0500 (EST)	[thread overview]
Message-ID: <> (raw)


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!
