ci: kernel-tracing runtime gate on a stock (no CONFIG_CONSTRUCTORS) kernel (1.7.5)#41
Merged
Conversation
Adds a CI job that boots the clltk kernel modules in QEMU on the stock distro kernel - which is built WITHOUT CONFIG_CONSTRUCTORS - and checks that tracing registers and produces trace files. This locks in the module-notifier init path (1.7.4): if registration ever regresses to depending on constructors, this job fails. No kernel build: the distro kernel-core package provides a bootable image and kernel-devel the matching build tree. On x86_64 the image is a bzImage QEMU boots directly; on aarch64 it is an EFI zboot (zstd) wrapper, so the raw Image is extracted from the zboot payload. Runs under TCG, no KVM required. Verified in the CI container: stock kernel (CONFIG_CONSTRUCTORS off), 5 trace files, zero invalid-offset errors. Signed-off-by: Jo5ta <jo5ta@mail.de>

Adds the CI regression gate for the module-notifier init path (1.7.4), and closes the "runtime kernel test" thread.
What it does: a new
kernel-runtimejob boots the clltk kernel modules in QEMU on the stock distro kernel — which is built withoutCONFIG_CONSTRUCTORS— and checks that tracing actually registers (trace files created, zeroinvalid in_file_offseterrors). If registration ever regresses to depending on the constructor, this job fails.No kernel build. It uses the distro
kernel-corepackage (bootable image) pluskernel-devel(matching build tree). On x86_64 the image is abzImageQEMU boots directly; on aarch64 the image is an EFI zboot (zstd) wrapper, so the script extracts the rawImagefrom the zboot payload. Runs under TCG — no KVM required.Verified in the CI container (aarch64 path): stock kernel with
CONFIG_CONSTRUCTORSoff, 5 trace files, zero invalid-offset errors →STOCK_KERNEL_TRACE_OK. The x86_64 CI runners take the simpler native-bzImage path.This complements the existing
build-kernel-modulejob (compile/link across kernel headers) with an actual runtime check on a realistic kernel config.
