[PATCH kernel-4.19] moduleparam: Save information about built-in modules in separate file
by Zhichang Yuan 18 Mar '21

18 Mar '21

From: Alexey Gladkov <gladkov.alexey(a)gmail.com> From: Alexey Gladkov <gladkov.alexey(a)gmail.com> mainline inclusion from mainline-v5.2-rc1 commit 898490c010b5d2e499e03b7e815fc214209ac583 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I390TB CVE: NA Backporting this patch is to fix an issue happened when the 5.10 kernel is building on openEuler 20.03 system. In openEuler 20.03 system, some modules ware built-in kernel. But in 5.10 kernel, those corresponding modules will be built as KO. For built-in kernel, kmode 2.7+ will fetch the modinfo from modules.builtin.modinfo which is only supported in kernel 5.2+. In the rpmbuild process, kernel spec will call kmod to query modinfo of the KO images. It will fail for 'file missing'. With backporting the mainline commit below, kmod can fetch any module's information from the corresponding module image or modules.builtin.modinfo. --------------------------- commit 898490c010b5d2e499e03b7e815fc214209ac583 upstream. Problem: When a kernel module is compiled as a separate module, some important information about the kernel module is available via .modinfo section of the module. In contrast, when the kernel module is compiled into the kernel, that information is not available. Information about built-in modules is necessary in the following cases: 1. When it is necessary to find out what additional parameters can be passed to the kernel at boot time. 2. When you need to know which module names and their aliases are in the kernel. This is very useful for creating an initrd image. Proposal: The proposed patch does not remove .modinfo section with module information from the vmlinux at the build time and saves it into a separate file after kernel linking. So, the kernel does not increase in size and no additional information remains in it. Information is stored in the same format as in the separate modules (null-terminated string array). Because the .modinfo section is already exported with a separate modules, we are not creating a new API. It can be easily read in the userspace: $ tr '\0' '\n' < modules.builtin.modinfo ext4.softdep=pre: crc32c ext4.license=GPL ext4.description=Fourth Extended Filesystem ext4.author=Remy Card, Stephen Tweedie, Andrew Morton, Andreas Dilger, Theodore Ts'o and others ext4.alias=fs-ext4 ext4.alias=ext3 ext4.alias=fs-ext3 ext4.alias=ext2 ext4.alias=fs-ext2 md_mod.alias=block-major-9-* md_mod.alias=md md_mod.description=MD RAID framework md_mod.license=GPL md_mod.parmtype=create_on_open:bool md_mod.parmtype=start_dirty_degraded:int ...

[PATCH kernel-4.19] brcmfmac: Loading the correct firmware for brcm43456

[PATCH kernel-4.19 01/52] moduleparam: Save information about built-in modules in separate file
by Yang Yingliang 18 Mar '21

18 Mar '21

From: Alexey Gladkov <gladkov.alexey(a)gmail.com> mainline inclusion from mainline-v5.2-rc1 commit 898490c010b5d2e499e03b7e815fc214209ac583 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I390TB CVE: NA Backporting this patch is to fix an issue happened when the 5.10 kernel is building on openEuler 20.03 system. In openEuler 20.03 system, some modules ware built-in kernel. But in 5.10 kernel, those corresponding modules will be built as KO. For built-in kernel, kmode 2.7+ will fetch the modinfo from modules.builtin.modinfo which is only supported in kernel 5.2+. In the rpmbuild process, kernel spec will call kmod to query modinfo of the KO images. It will fail for 'file missing'. With backporting the mainline commit below, kmod can fetch any module's information from the corresponding module image or modules.builtin.modinfo. --------------------------- Problem: When a kernel module is compiled as a separate module, some important information about the kernel module is available via .modinfo section of the module. In contrast, when the kernel module is compiled into the kernel, that information is not available. Information about built-in modules is necessary in the following cases: 1. When it is necessary to find out what additional parameters can be passed to the kernel at boot time. 2. When you need to know which module names and their aliases are in the kernel. This is very useful for creating an initrd image. Proposal: The proposed patch does not remove .modinfo section with module information from the vmlinux at the build time and saves it into a separate file after kernel linking. So, the kernel does not increase in size and no additional information remains in it. Information is stored in the same format as in the separate modules (null-terminated string array). Because the .modinfo section is already exported with a separate modules, we are not creating a new API. It can be easily read in the userspace: $ tr '\0' '\n' < modules.builtin.modinfo ext4.softdep=pre: crc32c ext4.license=GPL ext4.description=Fourth Extended Filesystem ext4.author=Remy Card, Stephen Tweedie, Andrew Morton, Andreas Dilger, Theodore Ts'o and others ext4.alias=fs-ext4 ext4.alias=ext3 ext4.alias=fs-ext3 ext4.alias=ext2 ext4.alias=fs-ext2 md_mod.alias=block-major-9-* md_mod.alias=md md_mod.description=MD RAID framework md_mod.license=GPL md_mod.parmtype=create_on_open:bool md_mod.parmtype=start_dirty_degraded:int ...
