Fri, 26 Jun 2026 11:15:36 +0200

selftests/liveupdate: add end to end test infrastructure and scriptsAdd the end to end testing infrastructure required to verify theliveupdate feature. This includes a custom init process, a testorchestration script, and a batch runner.The framework consists of:init.c:A lightweight init process that manages the kexec lifecycle.It mounts necessary filesystems, determines the current executionstage (1 or 2) via the kernel command line, and handles thekexec_file_load() sequence to transition between kernels.vmtest.sh:The primary KTAP-compliant test driver. It handles:- Kernel configuration merging and building.- Cross-compilation detection for x86_64 and arm64.- Generation of the initrd containing the test binary and init.- QEMU execution with automatic accelerator detection (KVM, HVF, or TCG).run-vmtests.sh:A wrapper that runs vmtest.sh for each LUO test across supportedarchitectures, providing a summary of pass/fail/skip results.Signed-off-by: Pasha Tatashin Co-developed-by: Jordan Richards Signed-off-by: Jordan Richards Co-developed-by: Mike Rapoport (Microsoft) Acked-by: Pratyush Yadav Link: https://patch.msgid.link/20260626-luo-vmtest-v0-v4-1-e7d3111cd5b3@kernel.orgSigned-off-by: Mike Rapoport (Microsoft) List of files: /linux/tools/testing/selftests/liveupdate/config

Also preparation for LUO - "Live Update Orchestrator" (Pasha Tatashin) is a major new feature targeted at cloud environments. Quoting the cover letter: This series introduces the Live Update Orchestrator, a kernel subsystem designed to facilitate live kernel updates using a kexec-based reboot. This capability is critical for cloud environments, allowing hypervisors to be updated with minimal downtime for running virtual machines. LUO achieves this by preserving the state of selected resources, such as memory, devices and their dependencies, across the kernel transition. As a key feature, this series includes support for preserving memfd file descriptors, which allows critical in-memory data, such as guest RAM or any other large memory region, to be maintained in RAM across the kexec reboot. Mike Rappaport merits a mention here, for his extensive review and testing work. - "kexec: reorganize kexec and kdump sysfs" (Sourabh Jain) moves the kexec and kdump sysfs entries from /sys/kernel/ to /sys/kernel/kexec/ and adds back-compatibility symlinks which can hopefully be removed one day - "kho: fixes for vmalloc restoration" (Mike Rapoport) fixes a BUG which was being hit during KHO restoration of vmalloc() regions* tag 'mm-nonmm-stable-2025-12-06-11-14' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (139 commits) calibrate: update header inclusion Reinstate "resource: avoid unnecessary lookups in find_next_iomem_res()" vmcoreinfo: track and log recoverable hardware errors kho: fix restoring of contiguous ranges of order-0 pages kho: kho_restore_vmalloc: fix initialization of pages array MAINTAINERS: TPM DEVICE DRIVER: update the W-tag init: replace simple_strtoul with kstrtoul to improve lpj_setup KHO: fix boot failure due to kmemleak access to non-PRESENT pages Documentation/ABI: new kexec and kdump sysfs interface Documentation/ABI: mark old kexec sysfs deprecated kexec: move sysfs entries to /sys/kernel/kexec test_kho: always print restore status kho: free chunks using free_page() instead of kfree() selftests/liveupdate: add kexec test for multiple and empty sessions selftests/liveupdate: add simple kexec-based selftest for LUO selftests/liveupdate: add userspace API selftests docs: add documentation for memfd preservation via LUO mm: memfd_luo: allow preserving memfd liveupdate: luo_file: add private argument to store runtime state mm: shmem: export some functions to internal.h ...

80bab43f6f235664fff2d3518b3901ba9c4ac5a3 - selftests/liveupdate: add userspace API selftests

Tue, 25 Nov 2025 17:58:46 +0100

selftests/liveupdate: add userspace API selftestsIntroduce a selftest suite for LUO. These tests validate the coreuserspace-facing API provided by the /dev/liveupdate device and itsassociated ioctls.The suite covers fundamental device behavior, session management, and thefile preservation mechanism using memfd as a test case. This providesregression 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 functionalityof LUO (e.g., session creation, file preservation). The post-kexecrestoration of resources is not covered, as the kselftest framework doesnot currently support orchestrating a reboot and continuing execution inthe new kernel.Link: https://lkml.kernel.org/r/20251125165850.3389713-17-pasha.tatashin@soleen.comSigned-off-by: Pasha Tatashin Reviewed-by: Pratyush Yadav Reviewed-by: Mike Rapoport (Microsoft) Tested-by: David Matlack Cc: Aleksander Lobakin Cc: Alexander Graf Cc: Alice Ryhl Cc: Andriy Shevchenko Cc: anish kumar Cc: Anna Schumaker Cc: Bartosz Golaszewski Cc: Bjorn Helgaas Cc: Borislav Betkov Cc: Chanwoo Choi Cc: Chen Ridong Cc: Chris Li Cc: Christian Brauner Cc: Daniel Wagner Cc: Danilo Krummrich Cc: Dan Williams Cc: David Hildenbrand Cc: David Jeffery Cc: David Rientjes Cc: Greg Kroah-Hartman Cc: Guixin Liu Cc: "H.
