Merge tag 'modules-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linuxPull modules updates from Luis Chamberlain: - The whole caching of module code into huge pages by Mike Rapoport is going in through Andrew Morton's tree due to some other code dependencies. That's really the biggest highlight for Linux kernel modules in this release. With it we share huge pages for modules, starting off with x86. Expect to see that soon through Andrew! - Helge Deller addressed some lingering low hanging fruit alignment enhancements by. It is worth pointing out that from his old patch series I dropped his vmlinux.lds.h change at Masahiro's request as he would prefer this to be specified in asm code [0]. [0] https://lore.kernel.org/all/20240129192644.3359978-5-mcgrof@kernel.org/T/#m9efef5e700fbecd28b7afb462c15eed8ba78ef5a - Matthew Maurer and Sami Tolvanen have been tag teaming to help get us closer to a modversions for Rust. In this cycle we take in quite a lot of the refactoring for ELF validation. I expect modversions for Rust will be merged by v6.14 as that code is mostly ready now. - Adds a new modules selftests: kallsyms which helps us tests find_symbol() and the limits of kallsyms on Linux today. - We have a realtime mailing list to kernel-ci testing for modules now which relies and combines patchwork, kpd and kdevops: https://patchwork.kernel.org/project/linux-modules/list/ https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/README.md https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/kernel-ci-kpd.md https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/linux-modules-kdevops-ci.md If you want to help avoid Linux kernel modules regressions, now its simple, just add a new Linux modules sefltests under tools/testing/selftests/module/ That is it. All new selftests will be used and leveraged automatically by the CI.* tag 'modules-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux: tests/module/gen_test_kallsyms.sh: use 0 value for variables scripts: Remove export_report.pl selftests: kallsyms: add MODULE_DESCRIPTION selftests: add new kallsyms selftests module: Reformat struct for code style module: Additional validation in elf_validity_cache_strtab module: Factor out elf_validity_cache_strtab module: Group section index calculations together module: Factor out elf_validity_cache_index_str module: Factor out elf_validity_cache_index_sym module: Factor out elf_validity_cache_index_mod module: Factor out elf_validity_cache_index_info module: Factor out elf_validity_cache_secstrings module: Factor out elf_validity_cache_sechdrs module: Factor out elf_validity_ehdr module: Take const arg in validate_section_offset modules: Add missing entry for __ex_table modules: Ensure 64-bit alignment on __ksymtab_* sections List of files: /linux/lib/tests/module/Makefile

84b4a51fce4ccc6605113ed8af41a3d91609a756 - selftests: add new kallsyms selftests

Mon, 21 Oct 2024 19:11:44 +0000

selftests: add new kallsyms selftestsWe lack find_symbol() selftests, so add one. This let's us stress testimprovements easily on find_symbol() or optimizations. It also inherentlyallows us to test the limits of kallsyms on Linux today.We test a pathalogical use case for kallsyms by introducing moduleswhich are automatically written for us with a larger number of symbols.We have 4 kallsyms test modules:A: has KALLSYSMS_NUMSYMS exported symbolsB: uses one of A's symbolsC: adds KALLSYMS_SCALE_FACTOR * KALLSYSMS_NUMSYMS exportedD: adds 2 * the symbols than CBy using anything much larger than KALLSYSMS_NUMSYMS as 10,000 andKALLSYMS_SCALE_FACTOR of 8 we segfault today. So we're capped ataround 160000 symbols somehow today. We can inpsect that issue atour leasure later, but for now the real value to this test is thatthis will easily allow us to test improvements on find_symbol().We want to enable this test on allyesmodconfig builds so we can'tuse this combination, so instead just use a safe value for now andbe informative on the Kconfig symbol documentation about where ourthresholds are for testers. We default then to KALLSYSMS_NUMSYMS ofjust 100 and KALLSYMS_SCALE_FACTOR of 8.On x86_64 we can use perf, for other architectures we just use 'time'and allow for customizations. For example a future enhancements couldbe done for parisc to check for unaligned accesses which triggers aspecial special exception handler assembler code inside the kernel.The negative impact on performance is so large on parisc that itkeeps track of its accesses on /proc/cpuinfo as UAH:IRQ: CPU0 CPU13: 1332 0 SuperIO ttyS07: 1270013 0 SuperIO pata_ns8741564: 320023012 320021431 CPU timer65: 17080507 20624423 CPU IPIUAH: 10948640 58104 Unaligned access handler trapsWhile at it, this tidies up lib/ test modules to allow us to havea new directory for them. The amount of test modules under lib/is insane.This should also hopefully showcase how to start doing basicself module writing code, which may be more useful for more complexcases later in the future.Signed-off-by: Luis Chamberlain List of files: /linux/lib/tests/module/Makefile
