When building kselftests/capabilities the following warning shows up:
clang -O2 -g -std=gnu99 -Wall test_execve.c -lcap-ng -lrt -ldl -o test_execve test_execve.c:121:13: warning: variable 'have_outer_privilege' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] } else if (unshare(CLONE_NEWUSER | CLONE_NEWNS) == 0) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ test_execve.c:136:9: note: uninitialized use occurs here return have_outer_privilege; ^~~~~~~~~~~~~~~~~~~~ test_execve.c:121:9: note: remove the 'if' if its condition is always true } else if (unshare(CLONE_NEWUSER | CLONE_NEWNS) == 0) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ test_execve.c:94:27: note: initialize the variable 'have_outer_privilege' to silence this warning bool have_outer_privilege; ^ = false
Rework so all the ksft_exit_*() functions have attribue '__attribute__((noreturn))' so the compiler knows that there wont be any return from the function. That said, without '__attribute__((noreturn))' the compiler warns about the above issue since it thinks that it will get back from the ksft_exit_skip() function, which it wont. Cleaning up the callers that rely on ksft_exit_*() return code, since the functions ksft_exit_*() have never returned anything.
