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.

* firmware: Restore support for built-in firmwareMarkus Trippelsdorf2017-09-161-1/+1
| | | | | | | | | | | | | | | Commit 5620a0d1aac ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum. The default for EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

For some minor reason, David Woodhouse didn't send the pull request at that point in time, and everyone forgot about this. The topic came up in the hallway track at the Plumbers conference this week, so here's a single patch that drops the whole firmware tree. The last firmware update was back in 2013, and all distros have been using linux-firmware instead since at least that year, if not before. The only commits to that directory since 2013 was some kbuild fixups for various build tool issues. So lets finally drop this, we don't need to lug them around in the kernel source tree anymore, especially as no one wants or uses them.

Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81") dropped the GNU Make 3.80 support, so we are now allowed to use those make-builtin helpers. This conversion will provide better portability without relying on the pwd command or its location /bin/pwd. I am intentionally using $(realpath ...) instead $(abspath ...) in some places. The difference between the two is $(realpath ...) returns an empty string if the given path does not exist. It is convenient in places where we need to error-out if the makefile fails to create an output directory.

The kernel does not use wchar_t string literals at this point, and xen does not use wchar_t at all (only efi_char16_t), so the flag has no effect, but as pointed out by Jan Beulich, adding a wchar_t string literal would be bad here. Since wchar_t is always defined as u16, independent of the toolchain default, always passing -fshort-wchar is correct and lets us remove the Xen specific hack along with fixing the warning.

|/ | | | | | | | | | | | | | | | | | | | | | | | I made the mistake of upgrading my desktop to the new Fedora 26 that comes with gcc-7.1.1. There's nothing wrong per se that I've noticed, but I now have 1500 lines of warnings, mostly from the new format-truncation warning triggering all over the tree. We use 'snprintf()' and friends in a lot of places, and often know that the numbers are fairly small (ie a controller index or similar), but gcc doesn't know that, and sees an 'int', and thinks that it could be some huge number. And then complains when our buffers are not able to fit the name for the ten millionth controller. These warnings aren't necessarily bad per se, and we probably want to look through them subsystem by subsystem, but at least during the merge window they just mean that I can't even see if somebody is introducing any *real* problems when I pull.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The thin archives build currently puts all lib.a and built-in.o files together and links them with --whole-archive. This works because thin archives can recursively refer to thin archives. However some architectures include libgcc.a, which may not be a thin archive, or it may not be constructed with the "P" option, in which case its contents do not get linked correctly. So don't pull .a libs into the root built-in.o archive. These libs should already have symbol tables and indexes built, so they can be direct linker inputs. Move them out of the --whole-archive option, which restore the conditional linking behaviour of lib.a to thin archives builds.

After all, we found that approach was not enough, and ended up with cleaning stale headers by commit cda2c65f981d ("kbuild: Remove stale asm-generic wrappers"). So, the extra search path is no longer needed because Kbuild invokes scripts/Makefile.asm-generic and remove stale headers before it starts descending. This commit is also reverting commit dc33db7c338e ("Kbuild: avoid duplicate include path") because we have no more duplicated path. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
