The following test program illustrates the memory corruption. You
would hope foo.b would be 42 but it is corrupted to -1.
#include <stdio.h>
#include <limits.h>
struct foo {
int a, b;
};
void kstrtol(long *x)
{
*x = -1;
}
int main(void)
{
struct foo foo;
foo.b = 42;
kstrtol((long *)&foo.a);
printf("%d %d\n", foo.a, foo.b);
return 0;
}
The error handling should return an error, it shouldn't just print
something. It shouldn't print anything actually, it should just
handle the error without printing or complaining. :P
