module: deprecate usage of *_gpl sections in module loader

2026-03-31T23:42:52Z

The *_gpl section are not being used populated by modpost anymore. Hence the module loader doesn't need to find and process these sections in modules. This patch also simplifies symbol finding logic in module loader since *_gpl sections don't have to be searched anymore.

module: use kflagstab instead of *_gpl sections

2026-03-31T23:42:52Z

Read kflagstab section for vmlinux and modules to determine whether kernel symbols are GPL only. This patch eliminates the need for fragmenting the ksymtab for infering the value of GPL-only symbol flag, henceforth stop populating *_gpl versions of the ksymtab and kcrctab in modpost.

module: move 'struct module_use' to internal.h

2025-07-31T11:40:46Z

The struct was moved to the public header file in commit c8e21ced08b3 ("module: fix kdb's illicit use of struct module_use."). Back then the structure was used outside of the module core. Nowadays this is not true anymore, so the structure can be made internal.

module: Move modprobe_path and modules_disabled ctl_tables into the module subsys

2025-07-23T09:52:47Z

Move module sysctl (modprobe_path and modules_disabled) out of sysctl.c and into the modules subsystem. Make modules_disabled static as it no longer needs to be exported. Remove module.h from the includes in sysctl as it no longer uses any module exported variables. This is part of a greater effort to move ctl tables into their respective subsystems which will reduce the merge conflicts in kernel/sysctl.c.

module: Add a separate function to mark sections as read-only after init

2025-05-18T11:56:21Z

Move the logic to mark special sections as read-only after module initialization into a separate function, along other related code in strict_rwx.c. Use a table with names of such sections to make it easier to add more.

module: Allow __module_address() to be called from RCU section.

2025-03-10T10:54:45Z

mod_find() uses either the modules list to find a module or a tree lookup (CONFIG_MODULES_TREE_LOOKUP). The list and the tree can both be iterated under RCU assumption (as well as RCU-sched). Remove module_assert_mutex_or_preempt() from __module_address() and entirely since __module_address() is the last user. Update comments.

module: Split module_enable_rodata_ro()

2025-01-26T12:05:24Z

module_enable_rodata_ro() is called twice, once before module init to set rodata sections readonly and once after module init to set rodata_after_init section readonly. The second time, only the rodata_after_init section needs to be set to read-only, no need to re-apply it to already set rodata. Split module_enable_rodata_ro() in two.

module: Constify 'struct module_attribute'

2025-01-26T12:05:23Z

These structs are never modified, move them to read-only memory. This makes the API clearer and also prepares for the constification of 'struct attribute' itself. While at it, also constify 'modinfo_attrs_count'.
