This patch adds rules with invalid user space supplied data:
        - out of range ruleset attribute;
        - unhandled allowed access;
        - zero port value;
        - zero access value;

Please add a test similar to TEST_F_FORK(layout1,
file_and_dir_access_rights) instead of explicitly defining and only
testing LANDLOCK_INVAL_ATTR.

      Do you want fs test to be in this commit or maybe its better to add
it into "[PATCH v7 01/18] landlock: rename access mask" one.

Just to make it clear, I didn't suggested an FS test, but a new network
test similar to layout1.file_and_dir_access_rights but only related to
the network. It should replace/extend the content of this patch (16/18).

   Ok. I will check out out "layout1.file_and_dir_access_rights" one.
But anyway we need some test like TEST_F_FORK(layout1, with_net) and
TEST_F_FORK(socket, with_fs) with mixed attributes as you suggested.

Right, you can add that to the main test patch.
