module.lds.S: Fix modules on 32-bit parisc architectureOn the 32-bit parisc architecture, we always used the-ffunction-sections compiler option to tell the compiler to put thefunctions into seperate text sections. This is necessary, otherwise"big" kernel modules like ext4 or ipv6 fail to load because somebranches won't be able to reach their stubs.Commit 1ba9f8979426 ("vmlinux.lds: Unify TEXT_MAIN, DATA_MAIN, and relatedmacros") broke this for parisc because all text sections will getunconditionally merged now.Introduce the ARCH_WANTS_MODULES_TEXT_SECTIONS config option whichavoids the text section merge for modules, and fix this issue byenabling this option by default for 32-bit parisc.Fixes: 1ba9f8979426 ("vmlinux.lds: Unify TEXT_MAIN, DATA_MAIN, and related macros")Cc: Josh Poimboeuf Cc: stable@vger.kernel.org # v6.19+Suggested-by: Sami Tolvanen Reviewed-by: Petr Pavlu Signed-off-by: Helge Deller List of files: /linux/scripts/module.lds.S

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 ...

9743311b4535dc76ce81f46303da0f69bfaa5fd6 - module: add kflagstab section to vmlinux and modules

Thu, 26 Mar 2026 21:25:03 +0000

module: add kflagstab section to vmlinux and modulesThis patch introduces a __kflagstab section to store symbol flags in adedicated data structure, similar to how CRCs are handled in the__kcrctab.The flags for a given symbol in __kflagstab will be located at the sameindex as the symbol's entry in __ksymtab and its CRC in __kcrctab. Thisdesign decouples the flags from the symbol table itself, allowing us tomaintain a single, sorted __ksymtab. As a result, the symbol searchremains an efficient, single lookup, regardless of the number of flagswe add in the future.The motivation for this change comes from the Android kernel, which usesan additional symbol flag to restrict the use of certain exportedsymbols by unsigned modules, thereby enhancing kernel security. This__kflagstab can be implemented as a bitmap to efficiently manage whichsymbols are available for general use versus those restricted to signedmodules only.This section will contain read-only data for values of kernel symbolflags in the form of an 8-bit bitsets for each kernel symbol. Each bitin the bitset represents a flag value defined by ksym_flags enumeration.Petr Pavlu ran a small test to get a better understanding of thedifferent section sizes resulting from this patch series. He usedv6.17-rc6 together with the openSUSE x86_64 config [1], which is fairlylarge. The resulting vmlinux.bin (no debuginfo) had an on-disk size of58 MiB, and included 5937 + 6589 (GPL-only) exported symbols.The following table summarizes his measurements and calculationsregarding the sizes of all sections related to exported symbols: | HAVE_ARCH_PREL32_RELOCATIONS | !HAVE_ARCH_PREL32_RELOCATIONS Section | Base [B] | Ext. [B] | Sep. [B] | Base [B] | Ext. [B] | Sep. [B]---------------------------------------------------------------------------------------- __ksymtab | 71244 | 200416 | 150312 | 142488 | 400832 | 300624 __ksymtab_gpl | 79068 | NA | NA | 158136 | NA | NA __kcrctab | 23748 | 50104 | 50104 | 23748 | 50104 | 50104 __kcrctab_gpl | 26356 | NA | NA | 26356 | NA | NA __ksymtab_strings | 253628 | 253628 | 253628 | 253628 | 253628 | 253628 __kflagstab | NA | NA | 12526 | NA | NA | 12526---------------------------------------------------------------------------------------- Total | 454044 | 504148 | 466570 | 604356 | 704564 | 616882 Increase to base [%] | NA | 11.0 | 2.8 | NA | 16.6 | 2.1The column "HAVE_ARCH_PREL32_RELOCATIONS -> Base" contains the measurednumbers. The rest of the values are calculated. The "Ext." columnrepresents an alternative approach of extending __ksymtab to include abitset of symbol flags, and the "Sep." column represents the approach ofhaving a separate __kflagstab. With HAVE_ARCH_PREL32_RELOCATIONS, eachkernel_symbol is 12 B in size and is extended to 16 B. With!HAVE_ARCH_PREL32_RELOCATIONS, it is 24 B, extended to 32 B. Note thatthis does not include the metadata needed to relocate __ksymtab*, whichis freed after the initial processing.Adding __kflagstab as a separate section has a negligible impact, asexpected. When extending __ksymtab (kernel_symbol) instead, the worstcase with !HAVE_ARCH_PREL32_RELOCATIONS increases the export data sizeby 16.6%. Note that the larger increase in size for the latter approachis due to 4-byte alignment of kernel_symbol data structure, instead of1-byte alignment for the flags bitset in __kflagstab in the formerapproach.Based on the above, it was concluded that introducing __kflagstab makessense, as the added complexity is minimal over extending kernel_symbol,and there is overall simplification of symbol finding logic in themodule loader.Signed-off-by: Siddharth Nayyar Reviewed-by: Petr Pavlu [Sami: Updated commit message to include details from the cover letter.]Signed-off-by: Sami Tolvanen List of files: /linux/scripts/module.lds.S

module.lds,codetag: force 0 sh_addr for sectionsCommit 1ba9f8979426 ("vmlinux.lds: Unify TEXT_MAIN, DATA_MAIN, andrelated macros") added .text and made .data, .bss, and .rodata sectionsunconditional in the module linker script, but without an explicitaddress like the other sections in the same file.When linking modules with ld.bfd -r, sections defined without an addressinherit the location counter, resulting in non-zero sh_addr values inthe .ko.

Fri, 23 Jan 2026 10:26:56 +0000

livepatch: Fix having __klp_objects relics in non-livepatch modulesThe linker script scripts/module.lds.S specifies that all input__klp_objects sections should be consolidated into an output section ofthe same name, and start/stop symbols should be created to enablescripts/livepatch/init.c to locate this data.This start/stop pattern is not ideal for modules because the symbols arecreated even if no __klp_objects input sections are present.Consequently, a dummy __klp_objects section also appears in theresulting module. This unnecessarily pollutes non-livepatch modules.Instead, since modules are relocatable files, the usual method forlocating 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 withthe final addresses. Introduce a helper function thatscripts/livepatch/init.c can call to obtain the location of the__klp_objects section from this data.Fixes: dd590d4d57eb ("objtool/klp: Introduce klp diff subcommand for diffing object files")Signed-off-by: Petr Pavlu Acked-by: Joe Lawrence Acked-by: Miroslav Benes Reviewed-by: Aaron Tomlin Link: https://patch.msgid.link/20260123102825.3521961-2-petr.pavlu@suse.comSigned-off-by: Josh Poimboeuf List of files: /linux/scripts/module.lds.S
