Subject: [PATCH v3 1/2] selftests: kselftest.h: mark functions with 'noreturn'
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.
