SYS_personality does not work correctly on mips(el)64

[Aurelien Jarno <aurelien@aurel32.net>]

Hi all,

On mips(el), when doing multiple call to the syscall SYS_personality in 
order to get the current personality (using 0xffffffff for the first 
argument), on a 64-bit kernel, the second and subsequent syscalls are 
failing. That works correctly with a 32-bit kernels and on other 
architectures.

Here is a small test below:

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

void main()
{
   printf("%i\n", personality(0xFFFFFFFF));
   printf("%i\n", personality(0xFFFFFFFF));
}


Bye,
Aurelien
