[LTP] [PATCH] cve-2015-3290: Handle 16-bit segments being disabled

[Cyril Hrubis]

Hi!

> +	TEST_ERRNO = -(int)TEST_RETURN;

We do have TRERRNO if we changed the test library to ignore the sign bit
we may was well get rid of this ugly hack and use TRERRNO in the
tst_brk() below.

> +	if (TEST_RETURN == -EINVAL) {

> +	} else if (TEST_RETURN != 0) {
> +		tst_brk(TBROK | TTERRNO, "modify_ldt");
> +	}
>  }
