[PATCH 0/2] Add io_uring test with Landlock access control rules

[Dorine Tipo <dorine.a.tipo@gmail.com>]

This patch series introduces a new test for verifying Landlock access
control rules with io_uring operation, IORING_OP_OPENAT.

The first patch (Add test for io_uring openat access control with Landlock
rules) implements the actual test.

- The test defines allowed and disallowed paths for access attempts.
- It creates Landlock rulesets for both allowed and disallowed access.
- It uses io_uring_prep_openat with the rulesets to attempt opening files.
- The test verifies successful preparation for allowed access and expects
submission failures for disallowed access.

The second patch  (Add liburing dependency for io_uring test) updates the
Makefile to include the necessary liburing library.

This patch series improves Landlock's test coverage by incorporating
io_uring operations and helps ensure Landlock effectively controls access
through io_uring.
It enhances the overall security posture of the system.

The test has been successfully compiled using make run_tests -C landlock
and successfully verifies Landlock access control with io_uring.
