* kbuild: Check for unknown options with cc-option usage in Kconfig and clangStephen Boyd2019-08-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit e8de12fb7cde2c85bc31097cd098da79a4818305 ] 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.

* kbuild: modpost: include .*.cmd files only when targets existMasahiro Yamada2019-08-061-4/+2
| | | | | | | | | | | | | | | | | | commit 944cfe9be1fbbec73bab2f7e77fe2e8f9c72970f upstream. If a build rule fails, the .DELETE_ON_ERROR special target removes the target, but does nothing for the .*.cmd file, which might be corrupted. So, .*.cmd files should be included only when the corresponding targets exist. Commit 392885ee82d3 ("kbuild: let fixdep directly write to .*.cmd files") missed to fix up this file.

* kconfig: Clear "written" flag to avoid data lossM. Vefa Bicakci2019-08-061-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | commit 0c5b6c28ed68becb692b43eae5e44d5aa7e160ce upstream. 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.

* fixdep: check return value of printf() and putchar()Masahiro Yamada2019-07-311-10/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 6f9ac9f4427ec0470ccffbf852cfaf326677cc21 ] When there is not enough space on your storage device, the build will fail with 'No space left on device' error message. The reason is obvious from the message, so you will free up some disk space, then you will resume the build. However, sometimes you may still see a mysterious error message: unterminated call to function 'wildcard': missing ')'. If you run out of the disk space, fixdep may end up with generating incomplete .*.cmd files. For example, if the disk-full error occurs while fixdep is running print_dep(), the .*.cmd might be truncated like this: $(wildcard include/config/ When you run 'make' next time, this broken .*.cmd will be included, then Make will terminate parsing since it is a wrong syntax. Once this happens, you need to run 'make clean' or delete the broken .*.cmd file manually. Even if you do not see any error message, the .*.cmd files after any error could be potentially incomplete, and unreliable. You may miss the re-compilation due to missing header dependency. If printf() cannot output the string for disk shortage or whatever reason, it returns a negative value, but currently fixdep does not check it at all. Consequently, fixdep *successfully* generates a broken .*.cmd file. Make never notices that since fixdep exits with 0, which means success. Given the intended usage of fixdep, it must respect the return value of not only malloc(), but also printf() and putchar(). This seems a long-standing issue since the introduction of fixdep. In old days, Kbuild tried to provide an extra safety by letting fixdep output to a temporary file and renaming it after everything is done: scripts/basic/fixdep $(depfile) $@ '$(make-cmd)' > $(dot-target).tmp;\ rm -f $(depfile); \ mv -f $(dot-target).tmp $(dot-target).cmd) It was no help to avoid the current issue; fixdep successfully created a truncated tmp file, which would be renamed to a .*.cmd file. This problem should be fixed by propagating the error status to the build system because: [1] Since commit 9c2af1c7377a ("kbuild: add .DELETE_ON_ERROR special target"), Make will delete the target automatically on any failure in the recipe. [2] Since commit 392885ee82d3 ("kbuild: let fixdep directly write to .*.cmd files"), .*.cmd file is included only when the corresponding target already exists.

* kconfig: fix missing choice values in auto.confMasahiro Yamada2019-07-262-4/+4

Since commit 00c864f8903d ("kconfig: allow all config targets to write auto.conf if missing"), Kconfig creates include/config/auto.conf in the defconfig stage when it is missing. 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.

* | kbuild: use more portable 'command -v' for cc-cross-prefixMasahiro Yamada2019-06-081-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To print the pathname that will be used by shell in the current environment, 'command -v' is a standardized way. [1] 'which' is also often used in scripts, but it is less portable. When I worked on commit bd55f96fa9fc ("kbuild: refactor cc-cross-prefix implementation"), I was eager to use 'command -v' but it did not work. (The reason is explained below.) I kept 'which' as before but got rid of '> /dev/null 2>&1' as I thought it was no longer needed. Sorry, I was wrong. It works well on my Ubuntu machine, but Alexey Brodkin reports noisy warnings on CentOS7 when 'which' fails to find the given command in the PATH environment. $ which foo which: no foo in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin) Given that behavior of 'which' depends on system (and it may not be installed by default), I want to try 'command -v' once again. The specification [1] clearly describes the behavior of 'command -v' when the given command is not found: Otherwise, no output shall be written and the exit status shall reflect that the name was not found. However, we need a little magic to use 'command -v' from Make. $(shell ...) passes the argument to a subshell for execution, and returns the standard output of the command. Here is a trick. GNU Make may optimize this by executing the command directly instead of forking a subshell, if no shell special characters are found in the command and omitting the subshell will not change the behavior. In this case, no shell special character is used. So, Make will try to run it directly. However, 'command' is a shell-builtin command, then Make would fail to find it in the PATH environment: $ make ARCH=m68k defconfig make: command: Command not found make: command: Command not found make: command: Command not found In fact, Make has a table of shell-builtin commands because it must ask the shell to execute them. Until recently, 'command' was missing in the table. This issue was fixed by the following commit: | commit 1af314465e5dfe3e8baa839a32a72e83c04f26ef | Author: Paul Smith <psmith@gnu.org> | Date: Sun Nov 12 18:10:28 2017 -0500 | | * job.c: Add "command" as a known shell built-in. | | This is not a POSIX shell built-in but it's common in UNIX shells. | Reported by Nick Bowler <nbowler@draconx.ca>. Because the latest release is GNU Make 4.2.1 in 2016, this commit is not included in any released versions. (But some distributions may have back-ported it.) We need to trick Make to spawn a subshell. There are various ways to do so: 1) Use a shell special character '~' as dummy $(shell : ~; command -v $(c)gcc) 2) Use a variable reference that always expands to the empty string (suggested by David Laight) $(shell command$${x:+} -v $(c)gcc) 3) Use redirect $(shell command -v $(c)gcc 2>/dev/null) I chose 3) to not confuse people. The stderr would not be polluted anyway, but it will provide extra safety, and is easy to understand.

|/ | | | | | | | | | | | | | | | | | | | Adding SPDX license identifier is pretty safe; however, here is one exception. Since commit ec8f24b7faaf ("treewide: Add SPDX license identifier - Makefile/Kconfig"), "make testconfig" would not pass. When Kconfig detects a circular file inclusion, it displays error messages with a file name and a line number prefixed to each line. The unit test checks if Kconfig emits the error messages correctly (this also checks the line number correctness). Now that the test input has the SPDX license identifier at the very top, the line numbers in the expected stderr should be incremented by 1.

Who knew that those deprecation warnings it was outputting actually meant we should change something? This set of fixes makes the build work again with Sphinx 2.0 and eliminates the warnings for 1.8. As part of that, we also need a few fixes to the docs for places where the new Sphinx is more strict. It is a bit late in the cycle for this kind of change, but it does fix problems that people are experiencing now. There has been some talk of raising the minimum version of Sphinx we support. I don't want to do that abruptly, though, so these changes add some glue to continue to support versions back to 1.3. We will be adding some infrastructure soon to nudge users of old versions forward, with the idea of maybe increasing our minimum version (and removing this glue) sometime in the future" * tag 'docs-5.2-fixes2' of git://git.lwn.net/linux: drm/i915: Maintain consistent documentation subsection ordering scripts/sphinx-pre-install: make it handle Sphinx versions docs: Fix conf.py for Sphinx 2.0 docs: fix multiple doc build warnings in enumeration.rst lib/list_sort: fix kerneldoc build error docs: fix numaperf.rst and add it to the doc tree doc: Cope with the deprecation of AutoReporter doc: Cope with Sphinx logging deprecations
