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, 13 Mar 2026 13:48:02 +0000

module: Fix freeing of charp module parameters when CONFIG_SYSFS=nWhen setting a charp module parameter, the param_set_charp() functionallocates memory to store a copy of the input value. Later, when the moduleis potentially unloaded, the destroy_params() function is called to freethis allocated memory.However, destroy_params() is available only when CONFIG_SYSFS=y, otherwiseonly a dummy variant is present. In the unlikely case that the kernel isconfigured with CONFIG_MODULES=y and CONFIG_SYSFS=n, this results ina memory leak of charp values when a module is unloaded.Fix this issue by making destroy_params() always available whenCONFIG_MODULES=y. Rename the function to module_destroy_params() to clarifythat it is intended for use by the module loader.Fixes: e180a6b7759a ("param: fix charp parameters set via sysfs")Signed-off-by: Petr Pavlu Signed-off-by: Sami Tolvanen List of files: /linux/kernel/params.c

32a92f8c89326985e05dce8b22d3f0aa07a3e1bd - Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

Sun, 22 Feb 2026 04:03:00 +0000

Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsThis converts some of the visually simpler cases that have been splitover multiple lines. I only did the ones that are easy to verify theresulting diff by having just that final GFP_KERNEL argument on the nextline.Somebody should probably do a proper coccinelle script for this, but forme the trivial script actually resulted in an assertion failure in themiddle of the script. I probably had made it a bit _too_ trivial.So after fighting that far a while I decided to just do some of thesyntactically simpler cases with variations of the previous 'sed'scripts.The more syntactically complex multi-line cases would mostly really wantwhitespace cleanup anyway.Signed-off-by: Linus Torvalds List of files: /linux/kernel/params.c

Merge tag 'modules-7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linuxPull module updates from Sami Tolvanen: "Module signing: - Remove SHA-1 support for signing modules. SHA-1 is no longer considered secure for signatures due to vulnerabilities that can lead to hash collisions. None of the major distributions use SHA-1 anymore, and the kernel has defaulted to SHA-512 since v6.11. Note that loading SHA-1 signed modules is still supported. - Update scripts/sign-file to use only the OpenSSL CMS API for signing. As SHA-1 support is gone, we can drop the legacy PKCS#7 API which was limited to SHA-1. This also cleans up support for legacy OpenSSL versions. Cleanups and fixes: - Use system_dfl_wq instead of the per-cpu system_wq following the ongoing workqueue API refactoring. - Avoid open-coded kvrealloc() in module decompression logic by using the standard helper. - Improve section annotations by replacing the custom __modinit with __init_or_module and removing several unused __INIT*_OR_MODULE macros. - Fix kernel-doc warnings in include/linux/moduleparam.h. - Ensure set_module_sig_enforced is only declared when module signing is enabled. - Fix gendwarfksyms build failures on 32-bit hosts.
