The SPDX identifier is a legally binding\nshorthand, which can be used instead of the full boiler plate text.\n\nThis patch is based on work done by Thomas Gleixner and Kate Stewart and\nPhilippe Ombredanne.\n\nHow this work was done:\n\nPatches were generated and checked against linux-4.14-rc6 for a subset of\nthe use cases:\n - file had no licensing information it it.\n - file was a */uapi/* one with no licensing information in it,\n - file was a */uapi/* one with existing licensing information,\n\nFurther patches will be generated in subsequent months to fix up cases\nwhere non-standard license headers were used, and references to license\nhad to be inferred by heuristics based on keywords.\n\nThe analysis to determine which SPDX License Identifier to be applied to\na file was done in a spreadsheet of side by side results from of the\noutput of two independent scanners (ScanCode \u0026 Windriver) producing SPDX\ntag:value files created by Philippe Ombredanne. Philippe prepared the\nbase worksheet, and did an initial spot review of a few 1000 files.\n\nThe 4.13 kernel was the starting point of the analysis with 60,537 files\nassessed. Kate Stewart did a file by file comparison of the scanner\nresults in the spreadsheet to determine which SPDX license identifier(s)\nto be applied to the file. She confirmed any determination that was not\nimmediately clear with lawyers working with the Linux Foundation.\n\nCriteria used to select files for SPDX license identifier tagging was:\n - Files considered eligible had to be source code files.\n - Make and config files were included as candidates if they contained \u003e5\n lines of source\n - File already had some variant of a license header in it (even if \u003c5\n lines).\n\nAll documentation files were explicitly excluded.\n\nThe following heuristics were used to determine which SPDX license\nidentifiers to apply.\n\n - when both scanners couldn\u0027t find any license traces, file was\n considered to have no license information in it, and the top level\n COPYING file license applied.\n\n For non */uapi/* files that summary was:\n\n SPDX license identifier # files\n ---------------------------------------------------|-------\n GPL-2.0 11139\n\n and resulted in the first patch in this series.\n\n If that file was a */uapi/* path one, it was \"GPL-2.0 WITH\n Linux-syscall-note\" otherwise it was \"GPL-2.0\". Results of that was:\n\n SPDX license identifier # files\n ---------------------------------------------------|-------\n GPL-2.0 WITH Linux-syscall-note 930\n\n and resulted in the second patch in this series.\n\n - if a file had some form of licensing information in it, and was one\n of the */uapi/* ones, it was denoted with the Linux-syscall-note if\n any GPL family license was found in the file or had no licensing in\n it (per prior point). Results summary:\n\n SPDX license identifier # files\n ---------------------------------------------------|------\n GPL-2.0 WITH Linux-syscall-note 270\n GPL-2.0+ WITH Linux-syscall-note 169\n ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21\n ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17\n LGPL-2.1+ WITH Linux-syscall-note 15\n GPL-1.0+ WITH Linux-syscall-note 14\n ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5\n LGPL-2.0+ WITH Linux-syscall-note 4\n LGPL-2.1 WITH Linux-syscall-note 3\n ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3\n ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1\n\n and that resulted in the third patch in this series.\n\n - when the two scanners agreed on the detected license(s), that became\n the concluded license(s).\n\n - when there was disagreement between the two scanners (one detected a\n license but the other didn\u0027t, or they both detected different\n licenses) a manual inspection of the file occurred.\n\n - In most cases a manual inspection of the information in the file\n resulted in a clear resolution of the license that should apply (and\n which scanner probably needed to revisit its heuristics).\n\n - When it was not immediately clear, the license identifier was\n confirmed with lawyers working with the Linux Foundation.\n\n - If there was any question as to the appropriate license identifier,\n the file was flagged for further research and to be revisited later\n in time.\n\nIn total, over 70 hours of logged manual review was done on the\nspreadsheet to determine the SPDX license identifiers to apply to the\nsource files by Kate, Philippe, Thomas and, in some cases, confirmation\nby lawyers working with the Linux Foundation.\n\nKate also obtained a third independent scan of the 4.13 code base from\nFOSSology, and compared selected files where the other two scanners\ndisagreed against that SPDX file, to see if there was new insights. The\nWindriver scanner is based on an older version of FOSSology in part, so\nthey are related.\n\nThomas did random spot checks in about 500 files from the spreadsheets\nfor the uapi headers and agreed with SPDX license identifier in the\nfiles he inspected. For the non-uapi files Thomas did random spot checks\nin about 15000 files.\n\nIn initial set of patches against 4.14-rc6, 3 files were found to have\ncopy/paste license identifier errors, and have been fixed to reflect the\ncorrect identifier.\n\nAdditionally Philippe spent 10 hours this week doing a detailed manual\ninspection and review of the 12,461 patched files from the initial patch\nversion early this week with:\n - a full scancode scan run, collecting the matched texts, detected\n license ids and scores\n - reviewing anything where there was a license detected (about 500+\n files) to ensure that the applied SPDX license was correct\n - reviewing anything where there was no detection but the patch license\n was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied\n SPDX license was correct\n\nThis produced a worksheet with 20 files needing minor correction. This\nworksheet was then exported into 3 different .csv files for the\ndifferent types of files to be modified.\n\nThese .csv files were then reviewed by Greg. Thomas wrote a script to\nparse the csv files and add the proper SPDX tag to the file, in the\nformat that the file expected. This script was further refined by Greg\nbased on the output to detect more types of files automatically and to\ndistinguish between header and source .c files (which need different\ncomment types.) Finally Greg ran the script using the .csv files to\ngenerate the patches.\n\nReviewed-by: Kate Stewart \u003ckstewart@linuxfoundation.org\u003e\nReviewed-by: Philippe Ombredanne \u003cpombredanne@nexb.com\u003e\nReviewed-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "75ba1d07fd6a494851db5132612944a9d4773f9c", "tree": "7a4d91412f3beefe884b3ef8cac536d304d66fa9", "parents": [ "f7a5f132b447cb6301ab3f0b0468a63db29e41f5" ], "author": { "name": "Joe Perches", "email": "joe@perches.com", "time": "Fri Oct 07 17:02:20 2016 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 07 18:46:30 2016 -0700" }, "message": "seq/proc: modify seq_put_decimal_[u]ll to take a const char *, not char\n\nAllow some seq_puts removals by taking a string instead of a single\nchar.\n\n[akpm@linux-foundation.org: update vmstat_show(), per Joe]\nLink: http://lkml.kernel.org/r/667e1cf3d436de91a5698170a1e98d882905e956.1470704995.git.joe@perches.com\nSigned-off-by: Joe Perches \u003cjoe@perches.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "34dbbcdbf63360661ff7bda6c5f52f99ac515f92", "tree": "56152a152ec895f7b9f49d529f2248b9c4eaed1f", "parents": [ "4046d6e81f33b7ef50d6668b78076d54c5e066b6" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 14 11:22:00 2016 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 14 12:56:09 2016 -0700" }, "message": "Make file credentials available to the seqfile interfaces\n\nA lot of seqfile users seem to be using things like %pK that uses the\ncredentials of the current process, but that is actually completely\nwrong for filesystem interfaces.\n\nThe unix semantics for permission checking files is to check permissions\nat _open_ time, not at read or write time, and that is not just a small\ndetail: passing off stdin/stdout/stderr to a suid application and making\nthe actual IO happen in privileged context is a classic exploit\ntechnique.\n\nSo if we want to be able to look at permissions at read time, we need to\nuse the file open credentials, not the current ones.

Due to historical reasons, we have some BUG code\n in bug.h and some in kernel.h -- i.e. the support for BUILD_BUG in\n linux/kernel.h predates the addition of linux/bug.h, but old code in\n kernel.h wasn\u0027t moved to bug.h at that time. As a band-aid, kernel.h\n was including \u003casm/bug.h\u003e to pseudo link them.\n\n This has caused confusion[1] and general yuck/WTF[2] reactions.
