* kconfig: use 'else ifneq' for Makefile to improve readabilityMasahiro Yamada2019-05-191-3/+1
| | | | | | | | | | 'ifeq ... else ifneq ... endif' notation is supported by GNU Make 3.81 or later, which is the requirement for building the kernel since commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81"). Use it to improve the readability. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* kbuild: check uniqueness of module namesMasahiro Yamada2019-05-181-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the recent build test of linux-next, Stephen saw a build error caused by a broken .tmp_versions/*.mod file: https://lkml.org/lkml/2019/5/13/991 drivers/net/phy/asix.ko and drivers/net/usb/asix.ko have the same basename, and there is a race in generating .tmp_versions/asix.mod Kbuild has not checked this before, and it suddenly shows up with obscure error messages when this kind of race occurs. Non-unique module names cause various sort of problems, but it is not trivial to catch them by eyes. Hence, this script. It checks not only real modules, but also built-in modules (i.e. controlled by tristate CONFIG option, but currently compiled with =y). Non-unique names for built-in modules also cause problems because /sys/modules/ would fall over. For the latest kernel, I tested "make allmodconfig all" (or more quickly "make allyesconfig modules"), and it detected the following: warning: same basename if the following are built as modules: drivers/regulator/88pm800.ko drivers/mfd/88pm800.ko warning: same basename if the following are built as modules: drivers/gpu/drm/bridge/adv7511/adv7511.ko drivers/media/i2c/adv7511.ko warning: same basename if the following are built as modules: drivers/net/phy/asix.ko drivers/net/usb/asix.ko warning: same basename if the following are built as modules: fs/coda/coda.ko drivers/media/platform/coda/coda.ko warning: same basename if the following are built as modules: drivers/net/phy/realtek.ko drivers/net/dsa/realtek.ko Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Kees Cook <keescook@chromium.org> Reviewed-by: Stephen Rothwell <sfr@canb.auug.org.au> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com>
* kconfig: Terminate menu blocks with a comment in the generated configAlexander Popov2019-05-181-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently menu blocks start with a pretty header but end with nothing in the generated config. So next config options stick together with the options from the menu block. Let's terminate menu blocks in the generated config with a comment and a newline if needed. Example: ...

* kbuild: remove 'addtree' and 'flags' magic for header search pathsMasahiro Yamada2019-05-183-33/+13
| | | | | | | | | | | | | | | | | | | The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated and ugly. As I mentioned in [1], Kbuild should stop automatic prefixing of header search path options. I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and 'flags' have been removed. Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj) to the header search path for O= building, but never touches extra compiler options from ccflags-y etc. [1]: https://patchwork.kernel.org/patch/9632347/ Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* treewide: prefix header search paths with $(srctree)/Masahiro Yamada2019-05-183-7/+7
| | | | | | | | | | | | | | | | | Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, conf_write() can be called with a directory name instead of a file name. As far as I see, this can happen for menuconfig, nconfig, gconfig. If it is given with a directory path, conf_write() kindly appends getenv("KCONFIG_CONFIG"), but this ends up with hacky dir/basename handling, and screwed up in corner-cases like "what if KCONFIG_CONFIG is an absolute path?" as discussed before: https://patchwork.kernel.org/patch/9910037/ Since conf_write() is already messed up, I'd say "do not do it". Please pass a file path all the time. If a directory path is specified for the configuration output, conf_write() will simply error out. Now that the tmp file is created in the same directory as the .config, the previously reported "what if KCONFIG_CONFIG points to a different file system?" has been solved.

This is a handful of changes to the kernel's gdb scripts to do some more debugging with kgdb. The first patch allows the vmlinux to be reloaded from where it was specified on the command line so that this set of scripts can be used from anywhere. The second patch adds a script to dump the config.gz to a file on the host debugging machine. The third patch adds some rb tree utilities and the last patch uses those rb tree walking utilities to dump out the contents of /proc/timer_list from a system under debug. This patch (of 5): If I run 'gdb <path/to/vmlinux>' and there's the vmlinux-gdb.py file there I can properly see symbols and use the lx commands provided by the GDB scripts. But once I run 'lx-symbols' at the command prompt, gdb reloads the vmlinux symbols assuming that this script was run from the directory that has vmlinux at the root. That isn't always true, but we could just look and see what symbols were already loaded and use that instead. Let's do that so this can work by being invoked anywhere.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The script broke on parsing function prototype for bpf_strtoul(). This is because the last argument for the function is a pointer to an "unsigned long". The current version of the script only accepts "const" and "struct", but not "unsigned", at the beginning of argument types made of several words. One solution could be to add "unsigned" to the list, but the issue could come up again in the future (what about "long int"?). It turns out we do not need to have such restrictions on the words: so let's simply accept any series of words instead.

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 ...

In order to allow recordmcount.pl to function correctly regardless of the current locale settings, set LANG=C when running objdump(1). LC_ALL is already unset in the top-level Makefile, so it is not necessary to also override that environment variable.

Right now KBUILD_MODPOST_WARN gets just ignored when KBUILD_EXTMOD is set which happens per default when building modules out of the tree. This change gives the opportunity to define module build behaving also in case of out of tree builds and default will become exit on error. Errors which can be detected by the build should be trapped out of the box there, unless somebody wants to notice broken stuff later at runtime. As this patch changes the default behaving from warning to error, users can consider to fix it for external module builds by: - providing module symbol table via KBUILD_EXTRA_SYMBOLS for modules which are dependent - OR getting old behaving back by passing KBUILD_MODPOST_WARN to the build Signed-off-by: Wladislav Wiebe <wladislav.wiebe@nokia.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

As commit 4f1127e20437 ("kbuild: fix infinite make recursion"), it caused some troubles in the past because Kbuild assumes O= as out-of-tree build, while it actually works in the source tree. Now this works more properly; if O= points to the source directory, it is handled as in-tree build. So, this sanity check is unneeded. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_DEBUG_INFO_BTF is enabled but available version of pahole is too old to support BTF generation, build script is supposed to emit warning and proceed with the build. Due to using exit instead of return from BASH function, existing handling code prematurely exits exit code 0, not completing some of the build steps. This patch fixes issue by correctly returning just from gen_btf() function only.
