Commit Message

Adhemerval Zanella Netto March 14, 2017, 8:24 p.m. UTC
Changes from previous version:

  - Change open tests from EINVAL to EISDIR.

--

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 length 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 and change open test.

And I did not used the -C -M option on this one... the following one is
essentially the same patch formatted with -C -M:

-/* This is not an exhaustive test: only system calls that can be
-   persuaded to fail with a consistent error code and no side effects
-   are included.  Usually these are failures due to invalid arguments,
-   with errno code EBADF or EINVAL.  The order of argument checks is
-   unspecified, so we must take care to provide arguments that only
-   allow _one_ failure mode.
-
-   Note that all system calls that can fail with EFAULT are permitted
-   to deliver a SIGSEGV signal instead, so we avoid supplying invalid
-   pointers in general, and we do not attempt to test system calls
-   that can only fail with EFAULT (e.g. gettimeofday, gethostname).
-
-   Also note that root-only system calls (e.g. acct, reboot) may, when
-   the test is run as an unprivileged user, fail due to insufficient
-   privileges before bothering to do argument checks, so those are not
-   tested either.
-
-   Also, system calls that take enum or a set of flags as argument is
-   not tested if POSIX doesn't specify exact binary values for all
-   flags, and so any value passed to flags may become valid.
-
-   Some tests assume "/bin/sh" names a file that exists and is not a
-   directory.  */
