Introduce a selftest suite for LUO. These tests validate the core
userspace-facing API provided by the /dev/liveupdate device and its
associated ioctls.
The suite covers fundamental device behavior, session management, and the
file preservation mechanism using memfd as a test case. This provides
regression testing for the LUO uAPI.
The following functionality is verified:
Device Access:
Basic open and close operations on /dev/liveupdate.
Enforcement of exclusive device access (verifying EBUSY on a
second open).
Session Management:
Successful creation of sessions with unique names.
Failure to create sessions with duplicate names.
File Preservation:
Preserving a single memfd and verifying its content remains
intact post-preservation.
Preserving multiple memfds within a single session, each with
unique data.
A complex scenario involving multiple sessions, each containing
a mix of empty and data-filled memfds.
Note: This test suite is limited to verifying the pre-kexec functionality
of LUO (e.g., session creation, file preservation). The post-kexec
restoration of resources is not covered, as the kselftest framework does
not currently support orchestrating a reboot and continuing execution in
the new kernel.
