With the latest llvm21 compiler, I hit several errors when building bpf
selftests. Some of errors look like below:
test_maps.c:565:40: error: variable 'val' is uninitialized when passed as a
const pointer argument here [-Werror,-Wuninitialized-const-pointer]
565 | assert(bpf_map_update_elem(fd, NULL, &val, 0) < 0 &&
| ^~~
prog_tests/bpf_iter.c:400:25: error: variable 'c' is uninitialized when passed
as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
400 | write(finish_pipe[1], &c, 1);
| ^
Some other errors have similar the pattern as the above.
These errors are fixed by initializing those variables properly.
