livepatch: Free klp_{object,func}_ext data after initialization

2026-02-05T16:00:45Z

The klp_object_ext and klp_func_ext data, which are stored in the __klp_objects and __klp_funcs sections, respectively, are not needed after they are used to create the actual klp_object and klp_func instances. This operation is implemented by the init function in scripts/livepatch/init.c. Prefix the two sections with ".init" so they are freed after the module is initializated.

livepatch: Fix having __klp_objects relics in non-livepatch modules

2026-02-05T16:00:44Z

The linker script scripts/module.lds.S specifies that all input __klp_objects sections should be consolidated into an output section of the same name, and start/stop symbols should be created to enable scripts/livepatch/init.c to locate this data. This start/stop pattern is not ideal for modules because the symbols are created even if no __klp_objects input sections are present. Consequently, a dummy __klp_objects section also appears in the resulting module. This unnecessarily pollutes non-livepatch modules. Instead, since modules are relocatable files, the usual method for locating consolidated data in a module is to read its section table. This approach avoids the aforementioned problem. The klp_modinfo already stores a copy of the entire section table with the final addresses. Introduce a helper function that scripts/livepatch/init.c can call to obtain the location of the __klp_objects section from this data.

livepatch/klp-build: Require Clang assembler >= 20

2026-01-29T18:09:26Z

Some special sections specify their ELF section entsize, for example: .pushsection section, "M", @progbits, 8 The entsize (8 in this example) is needed by objtool klp-diff for extracting individual entries. Clang assembler versions older than 20 silently ignore the above construct and set entsize to 0, resulting in the following error: .discard.annotate_data: missing special section entsize or annotations Add a klp-build check to prevent the use of Clang assembler versions prior to 20.

kbuild: Fix permissions of modules.builtin.modinfo

2026-01-28T10:51:25Z

Currently, modules.builtin.modinfo is created with executable permissions (0755). This is because after commit 39cfd5b12160 ("kbuild: extract modules.builtin.modinfo from vmlinux.unstripped"), modules.builtin.modinfo is extracted from vmlinux.unstripped using objcopy. When extracting sections, objcopy inherits attributes from the source ELF file. Since modules.builtin.modinfo is a data file and not an executable, it should have regular file permissions (0644). The executable bit can trigger warnings in Debian's Lintian tool. Explicitly remove the executable bit after generation.

kbuild: rpm-pkg: Generate debuginfo package manually

2026-01-28T10:51:24Z

Commit a7c699d090a1 ("kbuild: rpm-pkg: build a debuginfo RPM") adjusted the __spec_install_post macro to include __os_install_post, which runs brp-strip. This ends up stripping module signatures, breaking loading modules with lockdown enabled. Undo most of the changes of the aforementioned debuginfo patch and mirror commit 16c36f8864e3 ("kbuild: deb-pkg: use build ID instead of debug link for dbg package") in kernel.spec to generate a functionally equivalent debuginfo package while avoiding touching the modules after they have already been signed during modules_install.
