kbuild: Fix include path in scripts/Makefile.modpost
commit 23a0cb8e3225122496bfa79172005c587c2d64bf upstream. When building an external module, if users don't need to separate the compilation output and source code, they run the following command: "make -C $(LINUX_SRC_DIR) M=$(PWD)". At this point, "$(KBUILD_EXTMOD)" and "$(src)" are the same. If they need to separate them, they run "make -C $(KERNEL_SRC_DIR) O=$(KERNEL_OUT_DIR) M=$(OUT_DIR) src=$(PWD)". Before running the command, they need to copy "Kbuild" or "Makefile" to "$(OUT_DIR)" to prevent compilation failure. So the kernel should change the included path to avoid the copy operation. Signed-off-by: Jing Leng <jleng@ambarella.com> [masahiro: I do not think "M=$(OUT_DIR) src=$(PWD)" is the official way, but this patch is a nice clean up anyway.] Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> [nsc: updated context for v4.19] Signed-off-by: Nicolas Schier <n.schier@avm.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

ANDROID: kbuild: add support for clang LTO
This change adds the configuration option CONFIG_LTO_CLANG, and build system support for clang's Link Time Optimization (LTO). In preparation for LTO support for other compilers, potentially common parts of the changes are gated behind CONFIG_LTO instead. With -flto, instead of object files, clang produces LLVM bitcode, which is compiled into a native object at link time, allowing the final binary to be optimized globally. For more details, see: https://llvm.org/docs/LinkTimeOptimization.html While the kernel normally uses GNU ld for linking, LLVM supports LTO only with lld or GNU gold linkers.

Pull Kbuild updates from Masahiro Yamada:
"One of the most remarkable improvements in this cycle is, Kbuild is
now able to cache the result of shell commands. Some variables are
expensive to compute, for example, $(call cc-option,...) invokes the
compiler. It is not efficient to redo this computation every time,
even when we are not actually building anything. Kbuild creates a
hidden file ".cache.mk" that contains invoked shell commands and their
results. The speed-up should be noticeable.
Summary:
- Fix arch build issues (hexagon, sh)
- Clean up various Makefiles and scripts
- Fix wrong usage of {CFLAGS,LDFLAGS}_MODULE in arch Makefiles
- Cache variables that are expensive to compute
- Improve cc-ldopton and ld-option for Clang

Merge tag 'spdx_identifiers-4.14-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull initial SPDX identifiers from Greg KH:
"License cleanup: add SPDX license identifiers to some files
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the
'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally
binding shorthand, which can be used instead of the full boiler plate
text.
This patch is based on work done by Thomas Gleixner and Kate Stewart
and Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset
of the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to
license had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied
to a file was done in a spreadsheet of side by side results from of
the output of two independent scanners (ScanCode & Windriver)
producing SPDX tag:value files created by Philippe Ombredanne.
Philippe prepared the base worksheet, and did an initial spot review
of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537
files assessed. Kate Stewart did a file by file comparison of the
scanner results in the spreadsheet to determine which SPDX license
identifier(s) to be applied to the file. She confirmed any
determination that was not immediately clear with lawyers working with
the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained
>5 lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that
was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that
became the concluded license(s).
- when there was disagreement between the two scanners (one detected
a license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply
(and which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases,
confirmation by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.
The Windriver scanner is based on an older version of FOSSology in
part, so they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot
checks in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect
the correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial
patch version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch
license was not GPL-2.0 WITH Linux-syscall-note to ensure that the
applied SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Linus deleted the old code and put signing on the install command, I fixed it to extract the keyid and signer-name within sign-file and cleaned up that script now it always signs in-place. Some enthusiast should convert sign-key to perl and pull x509keyid into it. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

MODSIGN: Sign modules during the build process
If CONFIG_MODULE_SIG is set, then this patch will cause all modules files to
to have signatures added. The following steps will occur:
(1) The module will be linked to foo.ko.unsigned instead of foo.ko
(2) The module will be stripped using both "strip -x -g" and "eu-strip" to
ensure minimal size for inclusion in an initramfs.
(3) The signature will be generated on the stripped module.
(4) The signature will be appended to the module, along with some information
about the signature and a magic string that indicates the presence of the
signature.
Step (3) requires private and public keys to be available. By default these
are expected to be found in files:
signing_key.priv
signing_key.x509
in the base directory of the build. The first is the private key in PEM form
and the second is the X.509 certificate in DER form as can be generated from
openssl:
openssl req \
-new -x509 -outform PEM -out signing_key.x509 \
-keyout signing_key.priv -nodes \
-subj "/CN=H2G2/O=Magrathea/CN=Slartibartfast"
If the secret key is not found then signing will be skipped and the unsigned
module from (1) will just be copied to foo.ko.
If signing occurs, lines like the following will be seen:
LD [M] fs/foo/foo.ko.unsigned
STRIP [M] fs/foo/foo.ko.stripped
SIGN [M] fs/foo/foo.ko
will appear in the build log. If the signature step will be skipped and the
following will be seen:
LD [M] fs/foo/foo.ko.unsigned
STRIP [M] fs/foo/foo.ko.stripped
NO SIGN [M] fs/foo/foo.ko
NOTE! After the signature step, the signed module _must_not_ be passed through
strip. The unstripped, unsigned module is still available at the name on the
LD [M] line. This restriction may affect packaging tools (such as rpmbuild)
and initramfs composition tools.

scripts/Makefile.modpost: error in finding modules from .mod files.
This error may happen when the user's id or path includes .ko string. For example, user's id is xxx.ko and building test.ko module, the test.mod file lists ko name and all object files. /home/xxx.ko/kernel_dev/device/drivers/test.ko /home/xxx.ko/kernel_dev/device/drivers/test_main.o /home/xxx.ko/kernel_dev/device/drivers/test_io.o ...

kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command line
It is now possible to assign options to AS, CC and LD
on the command line - which is only used when building modules.
{A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
in the arch makefiles, thus users had no way to specify
additional options to AS, CC, LD when building modules
without overriding the original value.
Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE
that is used by arch specific files and free up
{A,C,LD}FLAGS_MODULE so they can be assigned on
the command line.
All arch Makefiles that used the old variables has been updated.
Note: Previously we had a MODFLAGS variable for both
AS and CC. But in favour of consistency this was dropped.
So in some cases arch Makefile has one assignmnet replaced by
two assignmnets.
Note2: MODFLAGS was not documented and is dropped
without any notice. I do not expect much/any breakage
from this.

kbuild: fix $(src) assignmnet with external modules
When we introduced support for KBUILD_EXTRA_SYMBOLS we started to include the externam module's kbuild file when doing the final modpost step. As external modules often do: ccflags-y := -I$(src) We had problems because $(src) was unassinged and gcc then used the next parameter for -I resulting in strange build failures. Fix is to assign $(src) and $(obj) when building external modules.

kbuild: soften modpost checks when doing cross builds
The module alias support in the kernel have a consistency check where it is checked that the size of a structure in the kernel and on the build host are the same. For cross builds this check does not make sense so detect when we do cross builds and silently skip the check in these situations. This fixes a build bug for a wireless driver when cross building for arm.

Linux Kernel Markers: create modpost file
This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.

kbuild: add verbose option to Section mismatch reporting in modpost
If the config option CONFIG_SECTION_MISMATCH is not set and we see a Section mismatch present the following to the user: modpost: Found 1 section mismatch(es). To see additional details select "Enable full Section mismatch analysis" in the Kernel Hacking menu (CONFIG_SECTION_MISMATCH). If the option CONFIG_SECTION_MISMATCH is selected then be verbose in the Section mismatch reporting from mdopost. Sample outputs: WARNING: o-x86_64/vmlinux.o(.text+0x7396): Section mismatch in reference from the function discover_ebda() to the variable .init.data:ebda_addr The function discover_ebda() references the variable __initdata ebda_addr. This is often because discover_ebda lacks a __initdata annotation or the annotation of ebda_addr is wrong.

kbuild: do section mismatch check on full vmlinux
Previously we did do the check on the .o files used to link vmlinux but that failed to find questionable references across the .o files. Create a dedicated vmlinux.o file used only for section mismatch checks that uses the defualt linker script so section does not get renamed. The vmlinux.o may later be used as part of the the final link of vmlinux but for now it is used fo section mismatch only. For a defconfig build this is instant but for an allyesconfig this add two minutes to a full build (that anyways takes ~2 hours). Signed-off-by: Sam Ravnborg <sam@ravnborg.org> |

At stage 2 modpost utility is used to check modules. In case of unresolved symbols modpost only prints warning.
