If coccicheck fails, it should return an error code distinct from zero
to signal about an internal problem. Current code instead of exiting with
the tool's error code returns the error code of 'echo "coccicheck failed"'
which is almost always equals to zero, thus failing the original intention
of alerting about a problem. This patch fixes the code.

The rule of mainmenu_stmt does not have debug print of zconf_lineno(),
but if it had, it would print a wrong line number for the same reason
as commit b2d00d7c61c8 ("kconfig: fix line numbers for if-entries in

The mainmenu_stmt does not need to eat following empty lines because
they are reduced to common_stmt.

With gcc-8 fsanitize=null become very noisy. GCC started to complain
about things like &a->b, where 'a' is NULL pointer. There is no NULL
dereference, we just calculate address to struct member. It's
technically undefined behavior so UBSAN is correct to report it. But as
long as there is no real NULL-dereference, I think, we should be fine.
-fno-delete-null-pointer-checks compiler flag should protect us from any
consequences. So let's just no use -fsanitize=null as it's not useful
for us. If there is a real NULL-deref we will see crash. Even if
userspace mapped something at NULL (root can do this), with things like
SMAP should catch the issue.

If Make gets a fatal signal while a shell is executing, it may delete
the target file that the recipe was supposed to update. This is needed
to make sure that it is remade from scratch when Make is next run; if
Make is interrupted after the recipe has begun to write the target file,
it results in an incomplete file whose time stamp is newer than that
of the prerequisites files. Make automatically deletes the incomplete
file on interrupt unless the target is marked .PRECIOUS.
The situation is just the same as when the shell fails for some reasons.
Usually when a recipe line fails, if it has changed the target file at
all, the file is corrupted, or at least it is not completely updated.
Yet the file’s time stamp says that it is now up to date, so the next
time Make runs, it will not try to update that file.
However, Make does not cater to delete the incomplete target file in
this case. We need to add .DELETE_ON_ERROR somewhere in the Makefile
to request it.
scripts/Kbuild.include seems a suitable place to add it because it is
included from almost all sub-makes.
Please note .DELETE_ON_ERROR is not effective for phony targets.
The external module building should never ever touch the kernel tree.
The following recipe fails if include/generated/autoconf.h is missing.
However, include/config/auto.conf is not deleted since it is a phony
target.
PHONY += include/config/auto.conf
include/config/auto.conf:
$(Q)test -e include/generated/autoconf.h -a -e $@ || ( \
echo >&2; \
echo >&2 " ERROR: Kernel configuration is invalid."; \
echo >&2 " include/generated/autoconf.h or $@ are missing.";\

Currently, only syncconfig creates or updates include/config/auto.conf
and some other files. Other config targets create or update only the
.config file.
When you configure and build the kernel from a pristine source tree,
any config target is followed by syncconfig in the build stage since
include/config/auto.conf is missing.
We are moving compiler tests from Makefile to Kconfig. It means that
parsing Kconfig files will be more costly since Kconfig invokes the
compiler commands internally. Thus, we want to avoid invoking Kconfig
twice (one for *config to create the .config, and one for syncconfig
to synchronize the auto.conf). If auto.conf does not exist, we can
generate all configuration files in the first configuration stage,
which will save the syncconfig in the build stage.
Please note this should be done only when auto.conf is missing. If
*config blindly did this, time stamp files under include/config/ would
be unnecessarily touched, triggering unneeded rebuild of objects.
I assume a scenario like this:
1. You have a source tree that has already been built
with CONFIG_FOO disabled
2. Run "make menuconfig" to enable CONFIG_FOO
3. CONFIG_FOO turns out to be unnecessary.
Run "make menuconfig" again to disable CONFIG_FOO
4. Run "make"
In this case, include/config/foo.h should not be touched since there
is no change in CONFIG_FOO. The sync process should be delayed until
the user really attempts to build the kernel.
This commit has another motivation; I want to suppress the 'No such
file or directory' warning from the 'include' directive.
The top-level Makefile includes auto.conf with '-include' directive,
like this:
ifeq ($(dot-config),1)
-include include/config/auto.conf
endif
This looks strange because auto.conf is mandatory when dot-config is 1.
I guess only the reason of using '-include' is to suppress the warning
'include/config/auto.conf: No such file or directory' when building
from a clean tree. However, this has a side-effect; Make considers
the files included by '-include' are optional. Hence, Make continues
to build even if it fails to generate include/config/auto.conf. I will
change this in the next commit, but the warning message is annoying.
(At least, kbuild test robot reports it as a regression.)
With this commit, Kconfig will generate all configuration files together
with the .config and I guess it is a solution good enough to suppress
the warning.
Note:
GNU Make 4.2 or later does not display the warning from the 'include'
directive if include files are successfully generated. See GNU Make
commit 87a5f98d248f ("[SV 102] Don't show unnecessary include file
errors.") However, older GNU Make versions are still widely used.

syncconfig updates the .config only when sym_change_count > 0, i.e.
any change in config symbols has been detected.
Not only symbols but also comments are contained in the .config file.
If only comments are updated, they are not fed back to the .config,
then the stale comments are left-over. Of course, this is just a
matter of comments, but why not fix it.
I see some scenarios where this happens.
Scenario A:
1. You have a source tree that has already been configured.
2. Linus increments the version number in the top-level Makefile
(i.e. he commits a new release)
3. You pull it, and run 'make'
4. syncconfig is invoked because the environment variable,
KERNELVERSION is updated, but the .config is not updated since
no config symbol is changed.
5. The .config file contains a kernel version in the top line:
# Automatically generated file; DO NOT EDIT.
# Linux/arm64 4.18.0-rc2 Kernel Configuration
... which points to a previous version.
Scenario B:
1. You have a source tree that has already been configured.
2. You upgrade the compiler, but it still has the same version number.
This may happen if you regularly build the latest compiler from
the source code.
3. You run 'make'
4. syncconfig is invoked because the environment variable,
CC_VERSION_TEXT is updated, but the .config is not updated since
no config symbol is changed.
5. The .config file contains the version string of the compiler:
#
# Compiler: aarch64-linux-gcc (GCC) 9.0.0 20180628 (experimental)
#
... which carries the information of the old compiler.
If KCONFIG_NOSILENTUPDATE is set, syncconfig is not allowed to update
the .config file. Otherwise, it is fine to update it regardless of
sym_change_count.

'make syncconfig' creates some files such as include/config/auto.conf,
include/generate/autoconf.h, etc. but the necessary directory creation
relies on scripts/kconfig/Makefile.
To make Kconfig self-contained, create directories as needed in
conf_write_autoconf().
This change allows scripts/kconfig/Makefile cleanups; syncconfig can
be merged into simple-targets.

In Fedora, the debug information is packaged separately (foo-debuginfo) and
can be installed separately. There's been a long standing issue where only
one version of a debuginfo info package can be installed at a time. There's
been an effort for Fedora for parallel debuginfo to rectify this problem.
Part of the requirement to allow parallel debuginfo to work is that build ids
are unique between builds. The existing upstream rpm implementation ensures
this by re-calculating the build-id using the version and release as a
seed. This doesn't work 100% for the kernel because of the vDSO which is
its own binary and doesn't get updated when embedded.
Fix this by adding some data in an ELF note for both the kernel and modules.
The data is controlled via a Kconfig option so distributions can set it
to an appropriate value to ensure uniqueness between builds.
