clang static analysis reports an undefined return
security/selinux/ss/conditional.c:79:2: warning: Undefined or garbage value returned to caller [core.uninitialized.UndefReturn]
return s[0];
^~~~~~~~~~~
static int cond_evaluate_expr( ...
{
u32 i;
int s[COND_EXPR_MAXDEPTH];
for (i = 0; i < expr->len; i++)
...
return s[0];
When expr->len is 0, the loop which sets s[0] never runs.
So return -1 if the loop never runs.
