W^X mmap

[coypu]

Hi!

Why doesn't the following code get rejected by pax mprotect?

#include <sys/mman.h>
#include <stdio.h>

int main() {
        int * a;
        a = mmap(NULL, BUFSIZ, PROT_READ | PROT_WRITE | PROT_EXEC, MAP_ANON, 
-1, 2);
        if (a == MAP_FAILED)
                printf("mmap failed\n");
        return 0;
}


thanks.
