FYI, but report tht "mips and mipsel personality(2) support is broken"
* Roger Leigh <rleigh@debian.org> [2006-07-30 19:39]:
> personality(2) only works the first time it is called [in the lifetime
> of a process/program]. All subsequent calls return EPERM, which is
> not a documented return value; I can see no mention of it in
> kernel/execdomain.c. None of the other architectures I have tested
> (amd64, arm, i386, ia64, powerpc) behave this way: personality(2) is
> not a privileged call.
>
> This happens no matter what the value of persona is, even if it is
> just 0xffffffff to query the current personality.
>
> The attached testcase demonstrates the breakage. On a working
> platform (powerpc), the output is like this:
>
> ------------------------
> $ ./testpersona
> Getting personality
> Get returned '0'
> Setting personality '8'
> Set OK
> Getting personality
> Get returned '8'
> Setting personality '0'
> Set OK
> Getting personality
> Get returned '0'
> ------------------------
>
> 0 == PER_LINUX
> 8 == PER_LINUX32
>
> It successfully switched from PER_LINUX to PER_LINUX32 and back again,
> checking the personality before and after each change.
