With clang building selftests/bpf, I hit a few warnings like below:
.../bpf_iter.c:592:48: warning: variable 'expected_key_c' set but not used [-Wunused-but-set-variable]
__u32 expected_key_a = 0, expected_key_b = 0, expected_key_c = 0;
^
.../bpf_iter.c:688:48: warning: variable 'expected_key_c' set but not used [-Wunused-but-set-variable]
__u32 expected_key_a = 0, expected_key_b = 0, expected_key_c = 0;
^
.../tc_redirect.c:657:6: warning: variable 'target_fd' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
if (!ASSERT_OK_PTR(nstoken, "setns " NS_FWD))
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../tc_redirect.c:743:6: note: uninitialized use occurs here
if (target_fd >= 0)
^~~~~~~~~
Removing unused variables and initializing the previously-uninitialized variable
to ensure these warnings are gone.
