| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the missing GPLv2 SPDX license identifier. It appears this single file was missing from 7f904d7e1f3e ("treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 505"), which addressed all other files in scripts/coccinelle. Hence I added GPL-2.0-only consitently with the mentioned patch.

* | kbuild: show hint if subdir-y/m is used to visit module MakefileMasahiro Yamada2019-08-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod"), a module is no longer built in the following pattern: [Makefile] subdir-y := some-module [some-module/Makefile] obj-m := some-module.o You cannot write Makefile this way in upstream because modules.order is not correctly generated. subdir-y is used to descend to a sub-directory that builds tools, device trees, etc. For external modules, the modules order does not matter. So, the Makefile above was known to work. I believe the Makefile should be re-written as follows: [Makefile] obj-m := some-module/ [some-module/Makefile] obj-m := some-module.o However, people will have no idea if their Makefile suddenly stops working. In fact, I received questions from multiple people. Show a warning for a while if obj-m is specified in a Makefile visited by subdir-y or subdir-m. I touched the %/ rule to avoid false-positive warnings for the single target.

| | | | | | | | | | | | | | | | | | | | The modules.order files in directories visited by the chain of obj-y or obj-m are merged to the upper-level ones, and become parts of the top-level modules.order.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I removed the single target %.ko in commit ff9b45c55b26 ("kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod") because the modpost stage does not work reliably. For instance, the module dependency, modversion, etc. do not work if we lack symbol information from the other modules. Yet, some people still want to build only one module in their interest, and it may be still useful if it is used within those limitations.

* | kconfig: Clear "written" flag to avoid data lossM. Vefa Bicakci2019-08-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this commit, starting nconfig, xconfig or gconfig, and saving the .config file more than once caused data loss, where a .config file that contained only comments would be written to disk starting from the second save operation. This bug manifests itself because the SYMBOL_WRITTEN flag is never cleared after the first call to conf_write, and subsequent calls to conf_write then skip all of the configuration symbols due to the SYMBOL_WRITTEN flag being set. This commit resolves this issue by clearing the SYMBOL_WRITTEN flag from all symbols before conf_write returns.

* | kbuild: Check for unknown options with cc-option usage in Kconfig and clangStephen Boyd2019-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the particular version of clang a user has doesn't enable -Werror=unknown-warning-option by default, even though it is the default[1], then make sure to pass the option to the Kconfig cc-option command so that testing options from Kconfig files works properly. Otherwise, depending on the default values setup in the clang toolchain we will silently assume options such as -Wmaybe-uninitialized are supported by clang, when they really aren't. A compilation issue only started happening for me once commit 589834b3a009 ("kbuild: Add -Werror=unknown-warning-option to CLANG_FLAGS") was applied on top of commit b303c6df80c9 ("kbuild: compute false-positive -Wmaybe-uninitialized cases in Kconfig"). This leads kbuild to try and test for the existence of the -Wmaybe-uninitialized flag with the cc-option command in scripts/Kconfig.include, and it doesn't see an error returned from the option test so it sets the config value to Y. Then the Makefile tries to pass the unknown option on the command line and -Werror=unknown-warning-option catches the invalid option and breaks the build. Before commit 589834b3a009 ("kbuild: Add -Werror=unknown-warning-option to CLANG_FLAGS") the build works fine, but any cc-option test of a warning option in Kconfig files silently evaluates to true, even if the warning option flag isn't supported on clang. Note: This doesn't change cc-option usages in Makefiles because those use a different rule that includes KBUILD_CFLAGS by default (see the __cc-option command in scripts/Kbuild.incluide). The KBUILD_CFLAGS variable already has the -Werror=unknown-warning-option flag set. Thanks to Doug for pointing out the different rule.

Hence, the modules.order is not generated. For the vmlinux modpost, it is not necessary at all. Separate scripts/Makefile.modpost for the vmlinux/modules stages. This works more efficiently because the vmlinux modpost does not need to include .*.cmd files.

To keep track of modules, Kbuild creates a *.mod file in $(MODVERDIR) for every module it is building. Some post-processing steps read the necessary information from *.mod files. This avoids descending into directories again. This mechanism was introduced in 2003 or so. Later, commit 551559e13af1 ("kbuild: implement modules.order") added modules.order. So, we can simply read it out to know all the modules with directory paths. This is easier than parsing the first line of *.mod files. $(MODVERDIR) has a flat directory structure, that is, *.mod files are named only with base names. This is based on the assumption that the module name is unique across the tree. This assumption is really fragile. Stephen Rothwell reported a race condition caused by a module name conflict: https://lkml.org/lkml/2019/5/13/991 In parallel building, two different threads could write to the same $(MODVERDIR)/*.mod simultaneously. Non-unique module names are the source of all kind of troubles, hence commit 3a48a91901c5 ("kbuild: check uniqueness of module names") introduced a new checker script. However, it is still fragile in the build system point of view because this race happens before scripts/modules-check.sh is invoked. If it happens again, the modpost will emit unclear error messages. To fix this issue completely, create *.mod with full directory path so that two threads never attempt to write to the same file. $(MODVERDIR) is no longer needed. Since modules with directory paths are listed in modules.order, Kbuild is still able to find *.mod files without additional descending. I also killed cmd_secanalysis; scripts/mod/sumversion.c computes MD4 hash for modules with MODULE_VERSION(). When CONFIG_DEBUG_SECTION_MISMATCH=y, it occurs not only in the modpost stage, but also during directory descending, where sumversion.c may parse stale *.mod files. It would emit 'No such file or directory' warning when an object consisting a module is renamed, or when a single-obj module is turned into a multi-obj module or vice versa.

Currently, we parse the first line of '*.mod' files in $(MODVERDIR). Since we have duplicated functionality here, I plan to remove MODVERDIR entirely. In fact, modules.order is generated also for external modules in a broken format. It adds the 'kernel/' prefix to the absolute path of the module, like this: kernel//path/to/your/external/module/foo.ko This is fine for now since modules.order is not used for external modules. However, I want to sanitize the format everywhere towards the goal of removing MODVERDIR. We cannot change the format of installed module.{order,builtin}. So, 'make modules_install' will add the 'kernel/' prefix while copying them to $(MODLIB)/. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

In the 'prepare0' rule, scripts/Makefile.build creates an empty modules.order while processing 'obj=.' In the 'modules' rule, the top-level Makefile overwrites it with the correct list of modules. While this might be a good side-effect that modules.order is made empty every time (probably this is not intended functionality), I personally do not like this behavior. Create modules.order only when it is sensible to do so. This avoids creating the following pointless files: scripts/basic/modules.order scripts/dtc/modules.order scripts/gcc-plugins/modules.order scripts/genksyms/modules.order scripts/mod/modules.order scripts/modules.order scripts/selinux/genheaders/modules.order scripts/selinux/mdp/modules.order scripts/selinux/modules.order Going forward, $(objtree)/modules.order lists the modules that was built in the last successful build.

Joonas Kylmälä reported incorrect auto.conf generation under some circumstances. To reproduce it, apply the following diff: | --- a/arch/arm/configs/imx_v6_v7_defconfig | +++ b/arch/arm/configs/imx_v6_v7_defconfig | @@ -345,14 +345,7 @@ CONFIG_USB_CONFIGFS_F_MIDI=y | CONFIG_USB_CONFIGFS_F_HID=y | CONFIG_USB_CONFIGFS_F_UVC=y | CONFIG_USB_CONFIGFS_F_PRINTER=y | -CONFIG_USB_ZERO=m | -CONFIG_USB_AUDIO=m | -CONFIG_USB_ETH=m | -CONFIG_USB_G_NCM=m | -CONFIG_USB_GADGETFS=m | -CONFIG_USB_FUNCTIONFS=m | -CONFIG_USB_MASS_STORAGE=m | -CONFIG_USB_G_SERIAL=m | +CONFIG_USB_FUNCTIONFS=y | CONFIG_MMC=y | CONFIG_MMC_SDHCI=y | CONFIG_MMC_SDHCI_PLTFM=y And then, run: $ make ARCH=arm mrproper imx_v6_v7_defconfig You will see CONFIG_USB_FUNCTIONFS=y is correctly contained in the .config, but not in the auto.conf. Please note drivers/usb/gadget/legacy/Kconfig is included from a choice block in drivers/usb/gadget/Kconfig. So USB_FUNCTIONFS is a choice value. This is probably a similar situation described in commit beaaddb62540 ("kconfig: tests: test defconfig when two choices interact"). When sym_calc_choice() is called, the choice symbol forgets the SYMBOL_DEF_USER unless all of its choice values are explicitly set by the user. The choice symbol is given just one chance to recall it because set_all_choice_values() is called if SYMBOL_NEED_SET_CHOICE_VALUES is set. When sym_calc_choice() is called again, the choice symbol forgets it forever, since SYMBOL_NEED_SET_CHOICE_VALUES is a one-time aid. Hence, we cannot call sym_clear_all_valid() again and again. It is crazy to repeat set and unset of internal flags. However, we cannot simply get rid of "sym->flags &= flags | ~SYMBOL_DEF_USER;" Doing so would re-introduce the problem solved by commit 5d09598d488f ("kconfig: fix new choices being skipped upon config update"). To work around the issue, conf_write_autoconf() stopped calling sym_clear_all_valid(). conf_write() must be changed accordingly. Currently, it clears SYMBOL_WRITE after the symbol is written into the .config file. This is needed to prevent it from writing the same symbol multiple times in case the symbol is declared in two or more locations. I added the new flag SYMBOL_WRITTEN, to track the symbols that have been written. Anyway, this is a cheesy workaround in order to suppress the issue as far as defconfig is concerned. Handling of choices is totally broken. sym_clear_all_valid() is called every time a user touches a symbol from the GUI interface. To reproduce it, just add a new symbol drivers/usb/gadget/legacy/Kconfig, then touch around unrelated symbols from menuconfig. USB_FUNCTIONFS will disappear from the .config file. I added the Fixes tag since it is more fatal than before. But, this has been broken since long long time before, and still it is. We should take a closer look to fix this correctly somehow.

This is safe to do: the comment about noop_llseek says This is an implementation of ->llseek useable for the rare special case when userspace expects the seek to succeed but the (device) file is actually not able to perform the seek. In this case you use noop_llseek() instead of falling back to the default implementation of ->llseek. and in general noop_llseek was massively added to drivers in 6038f373a3dc (llseek: automatically add .llseek fop) when changing default for NULL .llseek from NOP to no_llseek with the idea to avoid breaking compatibility, if maybe some user-space program was using lseek on a device without caring about the result, but caring if it was an error or not.
