2025-10-07scripts/Makefile.extrawarn: Respect CONFIG_WERROR / W=e for hostprogsNathan Chancellor
Commit 27758d8c2583 ("kbuild: enable -Werror for hostprogs") unconditionally enabled -Werror for the compiler, assembler, and linker when building the host programs, as the build footprint of the host programs is small (thus risk of build failures from warnings are low) and that stage of the build may not have Kconfig values (thus CONFIG_WERROR could not be used as a precondition). While turning warnings into errors unconditionally happens in a few places within the kernel, it can be disruptive to people who may be building with newer compilers, such as while doing a bisect. While it is possible to avoid this behavior by passing HOSTCFLAGS=-w or HOSTCFLAGS=-Wno-error, it may not be the most intuitive for regular users not intimately familiar with Kbuild. Avoid being disruptive to the entire build by depending on the explicit opt-in of CONFIG_WERROR or W=e to enable -Werror and the like while building the host programs. While this means there is a small portion of the build that does not have -Werror enabled (namely scripts/kconfig/* and scripts/basic/fixdep), it is better than not having it altogether.

2025-10-06kbuild: uapi: Strip comments before size type checkGeert Uytterhoeven
On m68k, check_sizetypes in headers_check reports: ./usr/include/asm/bootinfo-amiga.h:17: found __[us]{8,16,32,64} type without #include <linux/types.h> This header file does not use any of the Linux-specific integer types, but merely refers to them from comments, so this is a false positive. As of commit c3a9d74ee413bdb3 ("kbuild: uapi: upgrade check_sizetypes() warning to error"), this check was promoted to an error, breaking m68k all{mod,yes}config builds.

2025-09-24Merge patch series "Add generated modalias to modules.builtin.modinfo"Nathan Chancellor
Alexey Gladkov says: The modules.builtin.modinfo file is used by userspace (kmod to be specific) to get information about builtin modules. Among other information about the module, information about module aliases is stored. This is very important to determine that a particular modalias will be handled by a module that is inside the kernel. There are several mechanisms for creating modalias for modules: The first is to explicitly specify the MODULE_ALIAS of the macro. In this case, the aliases go into the '.modinfo' section of the module if it is compiled separately or into vmlinux.o if it is builtin into the kernel. The second is the use of MODULE_DEVICE_TABLE followed by the use of the modpost utility. In this case, vmlinux.o no longer has this information and does not get it into modules.builtin.modinfo. For example: $ modinfo pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 modinfo: ERROR: Module pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 not found. $ modinfo xhci_pci name: xhci_pci filename: (builtin) license: GPL file: drivers/usb/host/xhci-pci description: xHCI PCI Host Controller Driver The builtin module is missing alias "pci:v*d*sv*sd*bc0Csc03i30*" which will be generated by modpost if the module is built separately. To fix this it is necessary to add the generated by modpost modalias to modules.builtin.modinfo. Fortunately modpost already generates .vmlinux.export.c for exported symbols. It is possible to add `.modinfo` for builtin modules and modify the build system so that `.modinfo` section is extracted from the intermediate vmlinux after modpost is executed.

2025-09-24kbuild: vmlinux.unstripped should always depend on .vmlinux.export.oAlexey Gladkov
Since .vmlinux.export.c is used to add generated by modpost modaliases for builtin modules the .vmlinux.export.o is no longer optional and should always be created. The generation of this file is not dependent on CONFIG_MODULES.

2025-09-24modpost: Create modalias for builtin modulesAlexey Gladkov
For some modules, modalias is generated using the modpost utility and the section is added to the module file. When a module is added inside vmlinux, modpost does not generate modalias for such modules and the information is lost. As a result kmod (which uses modules.builtin.modinfo in userspace) cannot determine that modalias is handled by a builtin kernel module. $ cat /sys/devices/pci0000:00/0000:00:14.0/modalias pci:v00008086d0000A36Dsv00001043sd00008694bc0Csc03i30 $ modinfo xhci_pci name: xhci_pci filename: (builtin) license: GPL file: drivers/usb/host/xhci-pci description: xHCI PCI Host Controller Driver Missing modalias "pci:v*d*sv*sd*bc0Csc03i30*" which will be generated by modpost if the module is built separately. To fix this it is necessary to generate the same modalias for vmlinux as for the individual modules. Fortunately '.vmlinux.export.o' is already generated from which '.modinfo' can be extracted in the same way as for vmlinux.o.

2025-09-24modpost: Add modname to mod_device_table aliasAlexey Gladkov

2025-09-24s390: vmlinux.lds.S: Reorder sectionsAlexey Gladkov
In the upcoming changes, the ELF_DETAILS macro will be extended with the ".modinfo" section, which will cause an error: >> s390x-linux-ld: .tmp_vmlinux1: warning: allocated section `.modinfo' not in segment >> s390x-linux-ld: .tmp_vmlinux2: warning: allocated section `.modinfo' not in segment >> s390x-linux-ld: vmlinux.unstripped: warning: allocated section `.modinfo' not in segment This happens because the .vmlinux.info use :NONE to override the default segment and tell the linker to not put the section in any segment at all.

2025-09-11MAINTAINERS: Update the DMA Rust entryDanilo Krummrich
Update the DMA Rust maintainers entry in the following two aspects: (1) Change Abdiel's entry to 'Reviewer'. (2) Take patches through the driver-core tree. Abdiel won't do any more maintainer work on the DMA (or scatterlist) infrastructure, but he'd like to be kept in the loop, hence change is entry to 'R:'. Analogous to [1], the DMA (and scatterlist) helpers are closely coupled with the core device infrastructure and the device lifecycle, hence take patches through the driver-core tree by default.

2025-09-12erofs: fix long xattr name prefix placementGao Xiang
Currently, xattr name prefixes are forcibly placed into the packed inode if the fragments feature is enabled, and users have no option to put them in plain form directly on disk. This is inflexible. First, as mentioned above, users should be able to store unwrapped long xattr name prefixes unconditionally (COMPAT_PLAIN_XATTR_PFX). Second, since we now have the new metabox inode to store metadata, it should be used when available instead of the packed inode.
