-Subject: [PATCH 1/2] Fix: Tests: race condition in test_event_tracker
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Background
-==========
-The `test_event_tracker` file contains test cases when the event
-generating app in executed in two distinct steps. Those two steps are
-preparation and execution.
- 1. the preparation is the launching the app in the background, and
- 2. the execution is actually generating the event that should or
- should not be traced depending on the test case.
-
-This is useful to test the tracker feature since we want to ensure that
-already running apps are notified properly when changing their tracking
-status.
-
-Issue
-=====
-The `test_event_vpid_track_untrack` test case suffers from a race
-condition that is easy to reproduce on Yocto.
-
-The issue is that sometimes events are end up the trace when none is
-expected.
-
-This is due to the absence of synchronization point at the launch of the
-app which leads to the app being scheduled in-between the track-untrack
-calls leading to events being recorded to the trace.
-
-It's easy to reproduce this issue on my machine by adding a `sleep 5`
-between the track and untrack calls and setting the `NR_USEC_WAIT`
-variable to 1.
-
-Fix
-===
-Using the testapp `--sync-before-last-event-touch` flag to make the app
-create a file when all but the last event are executed. We then have the
-app wait until we create a file (`--sync-before-last-event`) to generate
-that last event. This way, we are sure no event will be generated when
-running the track and untrack commands.
-
-Notes
-=====
-- This issue affects other test cases in this file.
-- This commit fixes a typo in the test header.
-- This commit adds `diag` calls to help tracking to what test the output
- relates to when reading the log.

+Subject: [PATCH] Fix: rotation-destroy-flush: fix session daemon abort if no
+ kernel module present
+
+Testing rotation-destroy-flush when no lttng kernel modules present, it would
+be failed with error message:
+
+ Error: Unable to load required module lttng-ring-buffer-client-discard
+ not ok 1 - Start session daemon
+ Failed test 'Start session daemon'
+ not ok 2 - Create session rotation_destroy_flush in -o /tmp/tmp.test_rot ...
+ ...
+
+This because test script that sets the LTTNG_ABORT_ON_ERROR environment
+variable. It's this environment variable that causes the sessiond to handle the
+kernel module loading failure as an abort rather than a warning.
+
+Using "check_skip_kernel_test" to detect whether the kernel module fails to
+load is expected or not. If the failure is expected, the script won't set that
+environment variable any more.
+
+Fixes: 3a174400
+("tests:add check_skip_kernel_test to check root user and lttng kernel modules")

+Subject: [PATCH] compat: off64_t is not defined by musl
+
+This helps compile with latest musl, where off64_t is not defined unless
+_LARGEFILE64_SOURCE is defined. On glibc, _LARGEFILE64_SOURCE is defined
+if _GNU_SOURCE is defined, so the problem is only seen with musl.
+
+Since the project uses AC_SYS_LARGEFILE, which from the autoconf doc:
+"arrange for 64-bit file offsets, known as large-file support."
+
+As such, it is safe to assume off_t is 64-bit wide. This is checked by a
+static_assert to catch any platform where autoconf would let a 32-bit
+off_t slip.

+Subject: [PATCH] tests: add check_skip_kernel_test to check root user and
+ lttng kernel modules
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The current tests will run both userspace and kernel testing. Some of
+use cases only use lttng for one kind of tracing on an embedded
+device (e.g. userspace), so in this scenario, the kernel modules might
+not install to target rootfs, the test cases would be fail and exit.
+
+Add LTTNG_TOOLS_DISABLE_KERNEL_TESTS to skip the lttng kernel features
+test, this flag can be set via "make":
+
+ make check LTTNG_TOOLS_DISABLE_KERNEL_TESTS=1
+
+When this flag was set, all kernel related testcases would be marked as
+SKIP in result.
+
+Since the the LTTNG_TOOLS_DISABLE_KERNEL_TESTS was checked in function
+check_skip_kernel_test, lots of testcases also need to check root
+permission, so merging the root permission checking into
+check_skip_kernel_test.

-From: Francis Deslauriers <francis.deslauriers@efficios.com>
-Date: Wed, 8 Sep 2021 10:16:23 -0400
-Subject: [PATCH 2/2] Fix: Tests: race condition in test_ns_contexts_change
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Issue
-=====
-The test script doesn't wait for the test application to complete before
-stopping the tracing session. The race is that depending on the
-scheduling the application is not always done generating events when the
-session is stopped.
-
-Fix
-===
-Make the test script wait for the termination of the test app before
-stopping the session.

-This is a bit ugly. Specifing abs_builddir as an RPATH is plain wrong when
-cross compiling. Sadly, removing the rpath makes libtool/automake do
-weird things and breaks the build as shared libs are no longer generated.
-
-We already try and delete the RPATH at do_install with chrpath however
-that does leave the path in the string table so it doesn't help us
-with reproducibility.
-
-Instead, hack in a bogus but harmless path, then delete it later in
-our do_install. Ultimately we may want to pass a specific path to use
-to configure if we really do need to set an RPATH at all. It is unclear
-to me whether the tests need that or not.
-
-Fixes reproducibility issues for lttng-tools.
