This patch fixes multiple issues of test-errno.c (9a56f8718341):
- Rename Linux test-errno.c to test-errno-linux.c to avoid build
the same source for both tests.
- Add a mlock check for 32 bits build running on 64 bits kernels.
Althuough man pages states that mlock fails with EINVAL if final
address overflows, kernels does not return it for aforementioned
condition (it returns ENOMEM instead). Although it seems to be
a kernel issue for compat syscall handling, I think it is worth
to still check syscall return and document the behavior.
- Initialize option lenght for setsockopt check.
Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits
kernel).
* posix/test-errno.c (do_test): Initialize setsockopt optlen.
* sysdeps/unix/sysv/linux/test-errno.c: Move to ...
* sysdeps/unix/sysv/linux/test-errno-linux.c: ... here.
(do_test): Handle mlock return on 64 bits kernels with 32 bits
binaries.
Checked on s390x (64bit) and s390 (31bit - running on a 64bit kernel).
Thanks.
