selftests/liveupdate: add userspace API selftests

2025-11-27T22:24:41+00:00

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.

selftests/Makefile: include $(INSTALL_DEP_TARGETS) in clean target to clean net/lib dependency

2025-09-16T23:05:02+00:00

The selftests 'make clean' does not clean the net/lib because it only processes $(TARGETS) and ignores $(INSTALL_DEP_TARGETS). This leaves compiled objects in net/lib after cleaning, requiring manual cleanup. Include $(INSTALL_DEP_TARGETS) in clean target to ensure net/lib dependency is properly cleaned.

Hook up nolibc-test with the kselftests framework. This enables CI systems and developers to easily execute the tests. While nolibc-test does not emit KTAP output itself that is not a problem, as the kselftest executor will wrap the output in KTAP.
