Previously the first run-vmtest action step would always search for vmlinux image in KERNEL_ROOT, and then copy it to path specified by inputs.vmlinuz However, the caller may want to pass vmlinux image directly. Change this behavior: search only inputs.vmlinuz was not passed. Signed-off-by: Ihor Solodrai <[email protected]>
Various changes in the scripts aimed to make run-vmtest action usable by libbpf/libbpf workflows: * Change how ALLOWLIST and DENYLIST are set up. A script executing in qemu (vmtest) is now expecting a single $ALLOWLIST_FILE and $DENYLIST_FILE which are parsed by read_lists as usual. This change makes it easier for an action caller to modify the lists, as they are often composed from a number of files. * Update vmtest init command (executed in qemu before the tests), to create a link from /boot to vmlinux being tested. This is necessary when older kernels are tested. * Allow some env variables to be defined outside of the scripts to give the caller more control over the action. That is, before setting a default value, check if the variable is set. * Remove env vars like $THISDIR, $PROJECT_NAME etc. in favor of $GITHUB_ACTION_PATH, $GITHUB_WORKSPACE and $KERNEL_ROOT * Move selftests running scripts from ci/vmtest to run-vmtest, so that they are local to the action Signed-off-by: Ihor Solodrai <[email protected]>

Adjust run-vmtest scripts so that the action is callable from libbpf/libbpf, particularly with pre-built kernels. More environment variables can now be set by a caller to direct the scripts behavior: SELFTESTS_BPF, VERISTAT_CONFIGS, VMLINUX, VMLINUZ A symlink to standard vmlinux location is created before vmtest is executed to accomodate older kernels. The command passed tp vmtest is refactored, separating generic vmtet init and VMTEST_SCRIPT execution. Search and processing of json test summaries is now noop in case when no summaries are found.

FETCH_DEPTH now controls how to get linux source. If it's 0, the snapshot is searched for and downloaded if found. Otherwise git clone --depth $FETCH_DEPTH is executed, and .git is preserved. Signed-off-by: Ihor Solodrai <[email protected]>
Changes in action inputs: * kernel-root is now a required input * kernel, kbuild-output and max-make-jobs are removed kernel-root input is required, because to build selftests one must to clone a kernel source tree first. The build script behavior can be directed more granularly with env variables: * KBUILD_OUTPUT now defaults to the kernel-root * VMLINUX_BTF now can be set externally * MAX_MAKE_JOBS can be set as env variable if desired Preparation script logic is removed: the rationale is that the caller is responsible for setting up required environment before building.

Introduce CACHED_KERNEL_BUILD variable and change download/build steps to make use of the cached incremental build on libbpf/ci workflows. Change parameters passed to build-selftests. Add a step preparing allow/denylist before running vmtest. Signed-off-by: Ihor Solodrai <[email protected]>
