2020-02-27kbuild: add dt_binding_check to PHONY in a correct placeMasahiro Yamada1-1/+2
The dt_binding_check is added to PHONY, but it is invisible when $(dtstree) is empty. So, it is not specified as phony for ARCH=x86 etc. Add it to PHONY outside the ifneq ... endif block. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Acked-by: Rob Herring <robh@kernel.org>
2020-02-27kbuild: add dtbs_check to PHONYMasahiro Yamada1-1/+1
The dtbs_check should be a phony target, but currently it is not specified so. 'make dtbs_check' works even if a file named 'dtbs_check' exists because it depends on another phony target, scripts_dtc, but we should not rely on it. Add dtbs_check to PHONY.

2020-01-07kbuild: create modules.builtin without Makefile.modbuiltin or tristate.confMasahiro Yamada1-16/+5
Commit bc081dd6e9f6 ("kbuild: generate modules.builtin") added infrastructure to generate modules.builtin, the list of all builtin modules. Basically, it works like this: - Kconfig generates include/config/tristate.conf, the list of tristate CONFIG options with a value in a capital letter. - scripts/Makefile.modbuiltin makes Kbuild descend into directories to collect the information of builtin modules. I am not a big fan of it because Kbuild ends up with traversing the source tree twice. I am not sure how perfectly it should work, but this approach cannot avoid false positives; even if the relevant CONFIG option is tristate, some Makefiles forces obj-m to obj-y. Some examples are: arch/powerpc/platforms/powermac/Makefile: obj-$(CONFIG_NVRAM:m=y) += nvram.o net/ipv6/Makefile: obj-$(subst m,y,$(CONFIG_IPV6)) += inet6_hashtables.o net/netlabel/Makefile: obj-$(subst m,y,$(CONFIG_IPV6)) += netlabel_calipso.o Nobody has complained about (or noticed) it, so it is probably fine to have false positives in modules.builtin. This commit simplifies the implementation. Let's exploit the fact that every module has MODULE_LICENSE(). (modpost shows a warning if MODULE_LICENSE is missing. If so, 0-day bot would already have blocked such a module.) I added MODULE_FILE to <linux/module.h>. When the code is being compiled as builtin, it will be filled with the file path of the module, and collected into modules.builtin.info. Then, scripts/link-vmlinux.sh extracts the list of builtin modules out of it. This new approach fixes the false-positives above, but adds another type of false-positives; non-modular code may have MODULE_LICENSE() by mistake. This is not a big deal, it is just the code is always orphan. We can clean it up if we like. You can see cleanup examples by: $ git log --grep='make.* explicitly non-modular' To sum up, this commits deletes lots of code, but still produces almost equivalent results. Please note it does not increase the vmlinux size at all. As you can see in include/asm-generic/vmlinux.lds.h, the .modinfo section is discarded in the link stage.

Currently, some sanity checks for uapi headers are done by scripts/headers_check.pl, which is wired up to the 'headers_check' target in the top Makefile. It is true compiling headers has better test coverage, but there are still several headers excluded from the compile test.

2019-11-15kbuild: remove header compile testMasahiro Yamada1-1/+0
There are both positive and negative options about this feature. At first, I thought it was a good idea, but actually Linus stated a negative opinion (https://lkml.org/lkml/2019/9/29/227). I admit it is ugly and annoying. The baseline I'd like to keep is the compile-test of uapi headers. (Otherwise, kernel developers have no way to ensure the correctness of the exported headers.) I will maintain a small build rule in usr/include/Makefile. Remove the other header test functionality. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2019-11-15kbuild: tell sparse about the $ARCHLuc Van Oostenryck1-0/+3
Sparse uses the same executable for all archs and uses flags like -m64, -mbig-endian or -D__arm__ for arch-specific parameters. But Sparse also uses value from the host machine used to build Sparse as default value for the target machine. This works, of course, well for native build but can create problems when cross-compiling, like defining both '__i386__' and '__arm__' when cross-compiling for arm on a x86-64 machine. Fix this by explicitely telling sparse the target architecture.

2019-11-11modpost: dump missing namespaces into a single modules.nsdeps fileMasahiro Yamada1-2/+2
The modpost, with the -d option given, generates per-module .ns_deps files. Kbuild generates per-module .mod files to carry module information. This is convenient because Make handles multiple jobs in parallel when the -j option is given. On the other hand, the modpost always runs as a single thread. I do not see a strong reason to produce separate .ns_deps files. This commit changes the modpost to generate just one file, modules.nsdeps, each line of which has the following format: <module_name>: <list of missing namespaces> Please note it contains *missing* namespaces instead of required ones. So, modules.nsdeps is empty if the namespace dependency is all good. This will work more efficiently because spatch will no longer process already imported namespaces. I removed the '(if needed)' from the nsdeps log since spatch is invoked only when needed. This also solves the stale .ns_deps problem reported by Jessica Yu: https://lkml.org/lkml/2019/10/28/467 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Tested-by: Jessica Yu <jeyu@kernel.org> Acked-by: Jessica Yu <jeyu@kernel.org> Reviewed-by: Matthias Maennich <maennich@google.com> Tested-by: Matthias Maennich <maennich@google.com>
2019-11-11modpost: do not invoke extra modpost for nsdepsMasahiro Yamada1-3/+2
'make nsdeps' invokes the modpost three times at most; before linking vmlinux, before building modules, and finally for generating .ns_deps files. Running the modpost again and again is not efficient. The last two can be unified. When the -d option is given, the modpost still does the usual job, and in addition, generates .ns_deps files.

git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux Pull modules updates from Jessica Yu: "The main bulk of this pull request introduces a new exported symbol namespaces feature. The number of exported symbols is increasingly growing with each release (we're at about 31k exports as of 5.3-rc7) and we currently have no way of visualizing how these symbols are "clustered" or making sense of this huge export surface. Namespacing exported symbols allows kernel developers to more explicitly partition and categorize exported symbols, as well as more easily limiting the availability of namespaced symbols to other parts of the kernel. For starters, we have introduced the USB_STORAGE namespace to demonstrate the API's usage. I have briefly summarized the feature and its main motivations in the tag below. Summary: - Introduce exported symbol namespaces. This new feature allows subsystem maintainers to partition and categorize their exported symbols into explicit namespaces. Module authors are now required to import the namespaces they need. Some of the main motivations of this feature include: allowing kernel developers to better manage the export surface, allow subsystem maintainers to explicitly state that usage of some exported symbols should only be limited to certain users (think: inter-module or inter-driver symbols, debugging symbols, etc), as well as more easily limiting the availability of namespaced symbols to other parts of the kernel. With the module import requirement, it is also easier to spot the misuse of exported symbols during patch review. Two new macros are introduced: EXPORT_SYMBOL_NS() and EXPORT_SYMBOL_NS_GPL(). The API is thoroughly documented in Documentation/kbuild/namespaces.rst. - Some small code and kbuild cleanups here and there" * tag 'modules-for-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: module: Remove leftover '#undef' from export header module: remove unneeded casts in cmp_name() module: move CONFIG_UNUSED_SYMBOLS to the sub-menu of MODULES module: remove redundant 'depends on MODULES' module: Fix link failure due to invalid relocation on namespace offset usb-storage: export symbols in USB_STORAGE namespace usb-storage: remove single-use define for debugging docs: Add documentation for Symbol Namespaces scripts: Coccinelle script for namespace dependencies. modpost: add support for generating namespace dependencies export: allow definition default namespaces in Makefiles or sources module: add config option MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS modpost: add support for symbol namespaces module: add support for symbol namespaces. export: explicitly align struct kernel_symbol module: support reading multiple values per modinfo tag
