Subject: [RELEASE] LTTng-modules 2.13.2 (Linux kernel tracer)
Date: Mon, 7 Mar 2022 16:17:55 -0500 (EST) [thread overview]
Message-ID: <1107588912.127428.1646687875294.JavaMail.zimbra@efficios.com> (raw)
Hi,
The 2.13.2 release of the LTTng kernel tracer includes a fix for the
syscall tracing feature. A bug crept into 2.13.0 which caused the
system call input arguments to be recorded on return from system call
rather than the output arguments. This fix was in the master branch of
lttng-modules, but was not cherry-picked into the 2.13 stable branch.
This missing backport went unnoticed through our CI integration
because the relevant kernel tracer tests were not part of lttng-tools
default test suite: "make check". This is now fixed in the lttng-tools
project.
This release also contains commits needed to trace the 5.17 kernels
(currently at v5.17-rc7).
Users of lttng-modules 2.13.0 and 2.13.1 should upgrade to 2.13.2
if they want to gather useful output arguments on return from system
call into their trace, rather than an extra copy of the system call
input arguments.
Thanks,
Mathieu
