License cleanup: add SPDX GPL-2.0 license identifier to files with no license 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.

perf intel-pt: Use shared x86 insn decoder Now that there's a common version of the decoder for all tools, use it instead of the local copy. Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync.

Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync.

It is called "prefix" but actually not x86 instruction prefix, so this adds insn.emulate_prefix_size field instead of reusing insn.prefixes. If x86 decoder finds a special sequence of instructions of XEN_EMULATE_PREFIX and 'ud2a; .ascii "kvm"', it just counts the length, set insn.emulate_prefix_size and fold it with the next instruction. In other words, the signature and the next instruction is treated as a single instruction.

This got broken recently by s/390, fix it by copying arch/s390/include/uapi/asm/perf_regs.h to tools/arch/s390/include/uapi/asm/, making this one be used by means of <asm/perf_regs.h> and updating tools/perf/check_headers.sh to make sure we are notified when the original changes, so that we can check if anything is needed on the tooling side. This would have been caught by the 'tarkpg' test entry in: $ make -C tools/perf build-test When run on a s/390 build system or container.

# simple diff check
perf intel-pt: Use shared x86 insn decoder Now that there's a common version of the decoder for all tools, use it instead of the local copy. Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync.

tools perf: Move from sane_ctype.h obtained from git to the Linux's original We got the sane_ctype.h headers from git and kept using it so far, but since that code originally came from the kernel sources to the git sources, perhaps its better to just use the one in the kernel, so that we can leverage tools/perf/check_headers.sh to be notified when our copy gets out of sync, i.e. when fixes or goodies are added to the code we've copied. This will help with things like tools/lib/string.c where we want to have more things in common with the kernel, such as strim(), skip_spaces(), etc so as to go on removing the things that we have in tools/perf/util/ and instead using the code in the kernel, indirectly and removing things like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements are made to the original code. Hopefully this also should help with reducing the difference of code hosted in tools/ to the one in the kernel proper.

perf tools: Grab a copy of libbpf's hashmap Allow use of hashmap in perf. Modify perf's check-headers.sh script to check that the files are kept in sync, in the same way kernel headers are checked. This will warn if they are out of sync at the start of a perf build. Committer note: This starts out of synch as a fix went thru the bpf tree, namely the one removing the needless libbpf_internal.h include in hashmap.h. There is also another change related to __WORDSIZE, that as is in tools/lib/bpf/hashmap.h causes the tools/perf/ build to fail in systems such as Alpine Linus, that uses the Musl libc, so we need an alternative way of having __WORDSIZE available, use the one used by tools/include/linux/bitops.h, that builds in all the systems I have build containers for. These differences will be resolved at some point, so keep the warning in check-headers.sh as a reminder.
