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.

selftests/pstore: add pstore test script for pre-reboot The pstore_tests script includes test cases which check pstore's behavior before crash (and reboot). The test cases are currently following. - Check pstore backend is registered - Check pstore console is registered - Check /dev/pmsg0 exists - Write unique string to /dev/pmsg0 The unique string written to /dev/pmsg includes UUID. The UUID is also left in 'uuid' file in order to enable us to check if the pmsg keeps the string correctly after reboot. Example usage is following. # cd /path/to/selftests # make run_tests -C pstore (or just .pstore/pstore_tests) make: Entering directory '/path/to/selftests/pstore' === Pstore unit tests (pstore_tests) === UUID=b49b02cf-b0c2-4309-be43-b08c3971e37f Checking pstore backend is registered ... ok backend=ramoops cmdline=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait mem=768M ramoops.mem_address=0x30000000 ramoops.mem_size=0x10000 Checking pstore console is registered ... ok Checking /dev/pmsg0 exists ... ok Writing unique string to /dev/pmsg0 ... ok selftests: pstore_tests [PASS] make: Leaving directory '/path/to/selftests/pstore' We can also see test logs later. # cat pstore/logs/20151001-072718_b49b02cf-b0c2-4309-be43-b08c3971e37f/pstore_tests.log Thu Oct 1 07:27:18 UTC 2015 === Pstore unit tests (pstore_tests) === UUID=b49b02cf-b0c2-4309-be43-b08c3971e37f Checking pstore backend is registered ... ok backend=ramoops cmdline=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait mem=768M ramoops.mem_address=0x30000000 ramoops.mem_size=0x10000 Checking pstore console is registered ... ok Checking /dev/pmsg0 exists ... ok Writing unique string to /dev/pmsg0 ... ok Signed-off-by: Hiraku Toyooka <hiraku.toyooka.gu@hitachi.com> Cc: Shuah Khan <shuahkh@osg.samsung.com> Cc: Tony Luck <tony.luck@intel.com> Cc: Anton Vorontsov <anton@enomsg.org> Cc: Colin Cross <ccross@android.com> Cc: Kees Cook <keescook@chromium.org> Cc: Mark Salyzyn <salyzyn@android.com> Cc: Seiji Aguchi <seiji.aguchi.tr@hitachi.com> Cc: linux-kernel@vger.kernel.org Cc: linux-api@vger.kernel.org Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>

x86, selftests: Add sigreturn selftest This is my sigreturn test, added mostly unchanged from its old home. It exercises the sigreturn(2) syscall, specifically focusing on its interactions with various IRET corner cases. It tests for correct behavior in several areas that were historically dangerously buggy. For example, it exercises espfix on kernels of both bitnesses under various conditions, and it contains testcases for several now-fixed bugs in IRET error handling. If you run it on older kernels without the fixes, your system will crash. It probably won't eat your data in the process. There is no released kernel on which the sigreturn_64 test will pass, but it passes on tip:x86/asm. I plan to switch to lib.mk for Linux 4.2. I'm not using the ksft_ helpers at all yet. I can do that later.

selftests/zram: Adding zram tests zram: Compressed RAM based block devices ---------------------------------------- The zram module creates RAM based block devices named /dev/zram<id> (<id> = 0, 1, ...). Pages written to these disks are compressed and stored in memory itself. These disks allow very fast I/O and compression provides good amounts of memory savings. Some of the usecases include /tmp storage, use as swap disks, various caches under /var and maybe many more :) Statistics for individual zram devices are exported through sysfs nodes at /sys/block/zram<id>/ This patch is to validate the zram functionality. Test interacts with block device /dev/zram<id> and sysfs nodes /sys/block/zram<id>/ zram.sh: sanity check of CONFIG_ZRAM and to run zram01 and zram02 tests zram01.sh: creates general purpose ram disks with different filesystems zram02.sh: creates block device for swap zram_lib.sh: create library with initialization/cleanup functions README: ZRAM introduction and Kconfig required.
