0001-tests-fix-ust-ctl-fuzz-with-Wl-z-now.patch tests: fix preload of liblttng-ust-ctl-fuzz.so with '-Wl,-z,now'
The 'robust_protocol" test pre-loads the "liblttng-ust-ctl-fuzz.so"
library into the session daemon via LD_PRELOAD. This test library uses
symbols from "liblttng-ust-ctl.so" without linking on it, this is not an
issue in the default "-z lazy" link mode where symbols are resolved at
runtime when called.

However when building with "-z now" symbols are resolved at program
startup [1] which is still not an issue in the case of the session
daemon since it's linked on "liblttng-ust-ctl.so" and thus the dynamic
linker can resolve these symbols.

The issue is that the session daemon binary we call with LD_PRELOAD is a
libtool wrapper, effectively a shell script which means all processes
started in the wrapper will also pre-load our test library and won't be
able to resolve the "liblttng-ust-ctl.so" symbols resulting in an
undefined symbol error.

The fix here is to explicitly link the test library with
"liblttng-ust-ctl.so" which ensures symbols can be resolved whatever the
link mode is.
