Merge tag 'modules-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linuxPull module updates from Sami Tolvanen: "Kernel symbol flags: - Replace the separate *_gpl symbol sections (__ksymtab_gpl and __kcrctab_gpl) with a unified symbol table and a new __kflagstab section. This section stores symbol flags, such as the GPL-only flag, as an 8-bit bitset for each exported symbol. This is a cleanup that simplifies symbol lookup in the module loader by avoiding table fragmentation and will allow a cleaner way to add more flags later if needed. Module signature UAPI: - Move struct module_signature to the UAPI headers to allow reuse by tools outside the kernel proper, such as kmod and scripts/sign-file. This also renames a few constants for clarity and drops unused signature types as preparation for hash-based module integrity checking work that's in progress. Sysfs: - Add a /sys/module//import_ns sysfs attribute to show the symbol namespaces imported by loaded modules. This makes it easier to verify driver API access at runtime on systems that care about such things (e.g. Android). Cleanups and fixes: - Force sh_addr to 0 for all sections in module.lds. This prevents non-zero section addresses when linking modules with 'ld.bfd -r', which confused elfutils. - Fix a memory leak of charp module parameters on module unload when the kernel is configured with CONFIG_SYSFS=n. - Override the -EEXIST error code returned by module_init() to userspace. This prevents confusion with the errno reserved by the module loader to indicate that a module is already loaded. - Simplify the warning message and drop the stack dump on positive returns from module_init(). - Drop unnecessary extern keywords from function declarations and synchronize parse_args() arguments with their implementation"* tag 'modules-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux: (23 commits) module: Simplify warning on positive returns from module_init() module: Override -EEXIST module return documentation: remove references to *_gpl sections module: remove *_gpl sections from vmlinux and modules module: deprecate usage of *_gpl sections in module loader module: use kflagstab instead of *_gpl sections module: populate kflagstab in modpost module: add kflagstab section to vmlinux and modules module: define ksym_flags enumeration to represent kernel symbol flags selftests/bpf: verify_pkcs7_sig: Use 'struct module_signature' from the UAPI headers sign-file: use 'struct module_signature' from the UAPI headers tools uapi headers: add linux/module_signature.h module: Move 'struct module_signature' to UAPI module: Give MODULE_SIG_STRING a more descriptive name module: Give 'enum pkey_id_type' a more specific name module: Drop unused signature types extract-cert: drop unused definition of PKEY_ID_PKCS7 docs: symbol-namespaces: mention sysfs attribute module: expose imported namespaces via sysfs module: Remove extern keyword from param prototypes ...

Fri, 05 Dec 2025 18:37:41 +0100

Merge tag 'tracepoints-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-tracePull unused tracepoints update from Steven Rostedt: "Detect unused tracepoints. If a tracepoint is defined but never used (TRACE_EVENT() created but no trace_() called), it can take up to or more than 5K of memory each. This can add up as there are around a hundred unused tracepoints with various configs. That is 500K of wasted memory. Add a make build parameter of "UT=1" to have the build warn if an unused tracepoint is detected in the build. This allows detection of unused tracepoints to be upstream so that outreachy and the mentoring project can have new developers look for fixing them, without having these warnings suddenly show up when someone upgrades their kernel. When all known unused tracepoints are removed, then the "UT=1" build parameter can be removed and unused tracepoints will always warn. This will catch new unused tracepoints after the current ones have been removed. Summary: - Separate out elf functions from sorttable.c Move out the ELF parsing functions from sorttable.c so that the tracing tooling can use it. - Add a tracepoint verifier tool to the build process If "UT=1" is added to the kernel command line, any unused tracepoints will trigger a warning at build time. - Do not warn about unused tracepoints for tracepoints that are exported There are sever cases where a tracepoint is created by the kernel and used by modules. Since there's no easy way to detect if these are truly unused since the users are in modules, if a tracepoint is exported, assume it will eventually be used by a module. Note, there's not many exported tracepoints so this should not be a problem to ignore them. - Have building of modules also detect unused tracepoints Do not only check the main vmlinux for unused tracepoints, also check modules. If a module is defining a tracepoint it should be using it. - Add the tracepoint-update program to the ignore file The new tracepoint-update program needs to be ignored by git"* tag 'tracepoints-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: scripts: add tracepoint-update to the list of ignores files tracing: Add warnings for unused tracepoints for modules tracing: Allow tracepoint-update.c to work with modules tracepoint: Do not warn for unused event that is exported tracing: Add a tracepoint verification check at build time sorttable: Move ELF parsing into scripts/elf-parse.[ch] List of files: /linux/scripts/Makefile

e30f8e61e2518a837837daa26cda3c8cc30f3226 - tracing: Add a tracepoint verification check at build time

Wed, 22 Oct 2025 02:43:40 +0200

tracing: Add a tracepoint verification check at build timeIf a tracepoint is defined via DECLARE_TRACE() or TRACE_EVENT() but nevercalled (via the trace_() function), its metadata is stillaround in memory and not discarded.When created via TRACE_EVENT() the situation is worse because theTRACE_EVENT() creates metadata that can be around 5k per trace event.Having unused trace events causes several thousand of wasted bytes.Add a verifier that injects a string of the name of the tracepoint itcalls that is added to the discarded section "__tracepoint_check".For every builtin tracepoint, its name (which is saved in the in-memorysection "__tracepoint_strings") will have its name also in the"__tracepoint_check" section if it is used.Add a new program that is run on build called tracepoint-update. This isexecuted on the vmlinux.o before the __tracepoint_check section isdiscarded (the section is discarded before vmlinux is created). Thisprogram will create an array of each string in the __tracepoint_checksection and then sort it. Then it will walk the strings in the__tracepoint_strings section and do a binary search to check if its nameis in the __tracepoint_check section. If it is not, then it is unused anda warning is printed.Note, this currently only handles tracepoints that are builtin and not inmodules.Enabling this currently with a given config produces:warning: tracepoint 'sched_move_numa' is unused.warning: tracepoint 'sched_stick_numa' is unused.warning: tracepoint 'sched_swap_numa' is unused.warning: tracepoint 'pelt_hw_tp' is unused.warning: tracepoint 'pelt_irq_tp' is unused.warning: tracepoint 'rcu_preempt_task' is unused.warning: tracepoint 'rcu_unlock_preempted_task' is unused.warning: tracepoint 'xdp_bulk_tx' is unused.warning: tracepoint 'xdp_redirect_map' is unused.warning: tracepoint 'xdp_redirect_map_err' is unused.warning: tracepoint 'vma_mas_szero' is unused.warning: tracepoint 'vma_store' is unused.warning: tracepoint 'hugepage_set_pmd' is unused.warning: tracepoint 'hugepage_set_pud' is unused.warning: tracepoint 'hugepage_update_pmd' is unused.warning: tracepoint 'hugepage_update_pud' is unused.warning: tracepoint 'block_rq_remap' is unused.warning: tracepoint 'xhci_dbc_handle_event' is unused.warning: tracepoint 'xhci_dbc_handle_transfer' is unused.warning: tracepoint 'xhci_dbc_gadget_ep_queue' is unused.warning: tracepoint 'xhci_dbc_alloc_request' is unused.warning: tracepoint 'xhci_dbc_free_request' is unused.warning: tracepoint 'xhci_dbc_queue_request' is unused.warning: tracepoint 'xhci_dbc_giveback_request' is unused.warning: tracepoint 'tcp_ao_wrong_maclen' is unused.warning: tracepoint 'tcp_ao_mismatch' is unused.warning: tracepoint 'tcp_ao_key_not_found' is unused.warning: tracepoint 'tcp_ao_rnext_request' is unused.warning: tracepoint 'tcp_ao_synack_no_key' is unused.warning: tracepoint 'tcp_ao_snd_sne_update' is unused.warning: tracepoint 'tcp_ao_rcv_sne_update' is unused.Some of the above is totally unused but others are not used due to their"trace_" functions being inside configs, in which case, the definedtracepoints should also be inside those same configs. Others arearchitecture specific but defined in generic code, where they shouldeither be moved to the architecture or be surrounded by #ifdef for thearchitectures they are for.This tool could be updated to process modules in the future.I'd like to thank Mathieu Desnoyers for suggesting using strings insteadof pointers, as using pointers in vmlinux.o required handling relocationsand it required implementing almost a full feature linker to do so.To enable this check, run the build with: make UT=1Note, when all the existing unused tracepoints are removed from the build,the "UT=1" will be removed and this will always be enabled whentracepoints are configured to warn on any new tracepoints. The reason thisisn't always enabled now is because it will introduce a lot of warningsfor the current unused tracepoints, and all bisects would end at thiscommit for those warnings.Link: https://lore.kernel.org/all/20250528114549.4d8a5e03@gandalf.local.home/Cc: Masami Hiramatsu Cc: Mark Rutland Cc: Mathieu Desnoyers Cc: Andrew Morton Cc: Arnd Bergmann Cc: Masahiro Yamada Cc: Nathan Chancellor Cc: Nicolas Schier Cc: Nick Desaulniers Cc: Catalin Marinas Cc: Linus Torvalds Cc: Randy Dunlap Cc: Stephen Rothwell Link: https://lore.kernel.org/20251022004452.920728129@kernel.orgSuggested-by: Mathieu Desnoyers # for using strings instead of pointersSigned-off-by: Steven Rostedt (Google) List of files: /linux/scripts/Makefile
