-Subject: [PATCH] Allow multiple attempts to connect to relayd.
-
-It is unclear why a session needs to be made
-unusable after a failure to connect to relayd
-since a check for a relayd connection is
-always made before a session can be configured.
-
-The behaviour was introduced in:

+Subject: [PATCH lttng-tools 2/2] Fix: test: unit: the tree origin can be a
+ symlink itself
+
+Problem:
+
+The base tree is defined as "/tmp/.....XXXXXX".
+On systems where "/tmp/" is itself a symlink utils_expand_path will
+expand the tree origin itself.
+
+For example on a base core-image-minimal Yocto build /tmp is a symlink
+to "/var/tmp", which is a symlink to "/var/volatile".
+
+utils_expand_path will return something like this for the symlink test:
+"/var/volative/.....XXXXXX/...." which is the valid result.
+
+Solution:
+
+Simply use realpath on the tree_origin and use this path to perform the
+test validation.
+
+This work was performed in the effort to support yocto fully and be able
+to run the test suite to detect problem as early as possible.

+Subject: [PATCH lttng-tools] Skip when testapp is not present
+
+We expect lttng-ust do be present, this is a wrong assumptions.
+
+This is a quick fix. The real fix is to either detect at runtime
+lttng-ust support or at build time (HAVE_LIBLTTNG_UST_CTL).
+
+This prevent hang for make check done on a build configured with
+--without-lttng-ust.
+
+Upstream-Status: Inappropriate [other]
+Reason: This patch is inappropriate for upstream for 2.10 stable release
+since we do not backport "superficial" fix to the test suite. We do
+backport when a test is broken. The fact that on --without-lttng-ust
+hang is not a "broken" test per-see. Still, a variation of this fix will
+be upstreamed in our master branch and possibly 2.11. The upstreamed
+version will split the test in kernel/ust test and skip them at the
+build system level. This patch is more succinct.

+Subject: [PATCH] Fix: getgrnam is not MT-Safe, use getgrnam_r
+
+Running the test suite under a Yocto musl build resulted in musl
+coredump due to double freeing.

+
+The problem was easily reproducible (~6 crash on ~300 runs). A prototype fix
+using mutex around the getgrnam yielded no crash in over 1000 runs. This
+patch yielded the same results as the prototype fix.
+
+Unfortunately we cannot rely on a mutex in liblttng-ctl since we cannot
+enforce the locking for the application using the lib.
+
+Use getgrnam_r instead.
+
+The previous implementation of utils_get_group_id returned the gid of
+the root group (0) on error/not found. lttng_check_tracing_group needs
+to know if an error/not found occured, returning the root group is not
+enough. We now return the gid via the passed parameter. The caller is
+responsible for either defaulting to the root group or propagating the
+error.
+
+We also do not want to warn when used in liblttng-ctl context. We might
+want to move the warning elsewhere in the future. For now, pass a bool
+if we need to warn or not.
