Merge tag 'liveupdate-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linuxPull liveupdate updates from Mike Rapoport: "Kexec Handover: - Fix size calculation in kho_preserved_memory_reserve() for preservations larger than 2 GiB Live Update Orchestrator: - move liveupdate selftest utilities into a library so that selftests of subsystems participating in liveupdate, e.g. PCI and VFIO, can use them and drop direct ioctl calls from the tests - add end to end liveupdate test infrastructure that allows running the tests across a kexec in QEMU - remove redundant INIT_LIST_HEAD in luo_session_alloc() - remember the error status of an FLB retrieve() and return it on subsequent attempts rather than retrying retrieve() with an FLB in an unexpected state - reference count the outgoing FLB so that it cannot be freed while a caller is using it, the same way it's done for the incoming FLB - reject nonzero reserved field in LIVEUPDATE_SESSION_FINISH so that it can be reused by a future extension"* tag 'liveupdate-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/liveupdate/linux: kho: fix size calculation in kho_preserved_memory_reserve() selftests/liveupdate: Move luo_test_utils.* into a reusable library selftests/liveupdate: Use luo_test_utils.c for liveupdate ioctl APIs liveupdate: Remember FLB retrieve() status liveupdate: Reference count outgoing FLB data liveupdate: reject nonzero reserved value for SESSION_FINISH liveupdate: Remove redundant INIT_LIST_HEAD in luo_session_alloc selftests/liveupdate: add end to end test infrastructure and scripts List of files: /linux/tools/testing/selftests/liveupdate/init.c

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/init.c
