* scripts: coccicheck: Use /usr/bin/envJarkko Sakkinen2023-02-251-1/+1
| | | | | | | | | | If bash is not located under /bin, coccicheck fails to run. In the real world, this happens for instance when NixOS is used in the host. Instead, use /usr/bin/env to locate the executable binary for bash.

* scripts: coccicheck: fix troubles on non-English buildsMauro Carvalho Chehab2021-05-181-1/+1
| | | | | | | | | | | | | | | | | | | | | When LANG is not set to English, the logic which checks the number of CPUs fail, as the messages can be localized, and the logic at: THREADS_PER_CORE=$(lscpu | grep "Thread(s) per core: " | tr -cd "[:digit:]") will not get the number of threads per core. This causes the script to not run properly, as it will produce a warning: $ make coccicheck COCCI=$PWD/scripts/coccinelle/misc/add_namespace.cocci MODE=report drivers/media/ ./scripts/coccicheck: linha 93: [: número excessivo de argumentos Fix it by forcing LANG=C when calling lscpu.

* scripts: coccicheck: Correct usage of make coccicheckSumera Priyadarsini2020-12-241-0/+12
| | | | | | | | | | | | | | | | | | | | The command "make coccicheck C=1 CHECK=scripts/coccicheck" results in the error: ./scripts/coccicheck: line 65: -1: shift count out of range This happens because every time the C variable is specified, the shell arguments need to be "shifted" in order to take only the last argument, which is the C file to test. These shell arguments mostly comprise flags that have been set in the Makefile. However, when coccicheck is specified in the make command as a rule, the number of shell arguments is zero, thus passing the invalid value -1 to the shift command, resulting in an error. Modify coccicheck to print correct usage of make coccicheck so as to avoid the error. Signed-off-by: Sumera Priyadarsini <sylphrenadin@gmail.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>

| | | | | | | | | | | scripts/ld-version.sh was, as its file name implies, originally intended for the GNU ld version, but is (ab)used for the spatch version too.

* scripts: coccicheck: Change default condition for parallelismSumera Priyadarsini2020-10-121-1/+1
| | | | | | | | | | | | Currently, Coccinelle uses at most one thread per core by default in machines with more than 2 hyperthreads. However, for systems with only 4 hyperthreads, this does not improve performance. Modify coccicheck to use all available threads in machines with upto 4 hyperthreads.

| | | | | | | | | | | | | | While fetching the number of threads per core with lscpu, the [:digit:] set is used for translation of digits from 0-9. However, using [:digit:] instead of "[:digit:]" does not seem to work uniformly for some shell types and configurations (such as zsh). Therefore, modify coccicheck to use double quotes around the [:digit:] set for uniformity and better portability.

* scripts: coccicheck: Change default value for parallelismSumera Priyadarsini2020-09-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | By default, coccicheck utilizes all available threads to implement parallelisation. However, when all available threads are used, a decrease in performance is noted. The elapsed time is minimum when at most one thread per core is used. For example, on benchmarking the semantic patch kfree.cocci for usb/serial using hyperfine, the outputs obtained for J=5 and J=2 are 1.32 and 1.90 times faster than those for J=10 and J=9 respectively for two separate runs. For the larger drivers/staging directory, minimium elapsed time is obtained for J=3 which is 1.86 times faster than that for J=12. The optimal J value does not exceed 6 in any of the test runs. The benchmarks are run on a machine with 6 cores, with 2 threads per core, i.e, 12 hyperthreads in all. To improve performance, modify coccicheck to use at most only one thread per core by default.

* scripts: coccicheck: Improve error feedback when coccicheck failsSumera Priyadarsini2020-09-131-2/+8
| | | | | | | | | | | | | Currently, coccicheck fails with only the message "coccicheck failed" and the error code for the failure. To obtain the error logs, one needs to specify a debug file using the DEBUG_FILE option.

| | | | | | | | | | | | | | If coccicheck fails, it should return an error code distinct from zero to signal about an internal problem. Current code instead of exiting with the tool's error code returns the error code of 'echo "coccicheck failed"' which is almost always equals to zero, thus failing the original intention of alerting about a problem.

* coccinelle: fix parallel build with CHECK=scripts/coccicheckMasahiro Yamada2017-11-231-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command "make -j8 C=1 CHECK=scripts/coccicheck" produces lots of "coccicheck failed" error messages. Julia Lawall explained the Coccinelle behavior as follows: "The problem on the Coccinelle side is that it uses a subdirectory with the name of the semantic patch to store standard output and standard error for the different threads. I didn't want to use a name with the pid, so that one could easily find this information while Coccinelle is running. Normally the subdirectory is cleaned up when Coccinelle completes, so there is only one of them at a time. Maybe it is best to just add the pid. There is the risk that these subdirectories will accumulate if Coccinelle crashes in a way such that they don't get cleaned up, but Coccinelle could print a warning if it detects this case, rather than failing." When scripts/coccicheck is used as CHECK tool and -j option is given to Make, the whole of build process runs in parallel. So, multiple processes try to get access to the same subdirectory. I notice spatch creates the subdirectory only when it runs in parallel (i.e. --jobs <N> is given and <N> is greater than 1). Setting NPROC=1 is a reasonable solution; spatch does not create the subdirectory. Besides, ONLINE=1 mode takes a single file input for each spatch invocation, so there is no reason to parallelize it in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you run coccicheck with V=1 and COCCI=, you will see a strange path to the semantic patch file.

Notice "s/" was dropped from "scripts/coccinelle/free/kfree.cocci".

Surprisingly, ld-version.sh can extract the version number from the string "Requires Coccinelle version 1.0.0-rc20 or later", but this expectation is fragile. Fix the .cocci file.

| | | | | | | | | | | | | | | | | | | | | | | | | | Make coccicheck checked for the existence of DEBUG_FILE on each semantic patch, and bailed if it already existed. This meant that DEBUG_FILE was useless for checking more than one semantic patch at a time. Now the check is moved to the start of make coccicheck, and the 2> is changed to a 2>> to append to the file on each semantic patch. Furthermore, the spatch command that is run for each semantic patch is also added to the DEBUG_FILE, to make clear what each stdout trace corresponds to.

* | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Just look for --jobs in the help output to determine if this is supported and use it only if your number of processors detected is > 1. If parmap is enabled also enable the load balancing to be dynamic, so that if a thread finishes early we keep feeding it. stderr is currently sent to /dev/null, addressing a way to capture that will be addressed next. If --jobs is not supported we fallback to the old mechanism. We expect to deprecate the old mechanism as soon as we can get confirmation all users are ready. While at it propagate back into the shell script any coccinelle error code. When used in serialized mode where all cocci files are run this also stops processing if an error has occured. This lets us handle some errors in coccinelle cocci files and if they bail out we should inspect the errors. This will be more useful later to help annotate coccinelle version dependency requirements. This will let you run only SmPL files that your system supports. Extend Documentation/coccinelle.txt as well. As a small example, prior to this change, on an 8-core system: Before: $ export COCCI=scripts/coccinelle/free/kfree.cocci $ time make coccicheck MODE=report ... real 29m14.912s user 103m1.796s sys 0m4.464s After: real 16m22.435s user 128m30.060s sys 0m2.712s v4: o expand Documentation/coccinelle.txt to reflect parmap support info o update commit log to reflect what we actually do now with stderr o split out DEBUG_FILE use into another patch o detect number of CPUs and if its 1 then skip parmap support, note that if you still support parmap, but have 1 CPU you will also go through the new branches, so the old complex multithreaded process is skipped as well. v3: o move USE_JOBS to avoid being overriden v2: o redirect coccinelle stderr to /dev/null by default and only if DEBUG_FILE is used do we pass it to a file o fix typo of paramap/parmap Signed-off-by: Luis R.

Reorder the way SPFLAGS is added to FLAGS, to allow for options in the SPFLAGS to override the default --very-quiet option. Similarly, rearrage the FLAGS for org or report mode. This allows for overriding of the default --no-show-diff option through SPFLAGS.

* Coccinelle: fix incorrect -include option transformationAndrzej Hajda2015-10-261-1/+1
| | | | | | | | | | kbuild/gcc uses -include option to include files and -I to provide paths for #include <> directive. In case of spatch latter option should be prefixed with two -.

* Coccinelle: Make 'report' the default modeNicolas Palix2013-06-141-3/+11
| | | | | | | | | | | | It appears that the 'report' mode is the one always provided by the semantic patches included in the kernel. It is thus more natural to select it by default. The 'chain' mode is however kept and the 'patch' mode is still the first tried in that case. Signed-off-by: Nicolas Palix <nicolas.palix@imag.fr> Signed-off-by: Michal Marek <mmarek@suse.cz>

* Coccinelle: Cleanup the setting of the FLAGS and OPTIONS variablesNicolas Palix2013-04-081-12/+13
| | | | | | | | | | | | | The FLAGS variable is factorized independently of the ONLINE mode. The OPTIONS variable is now based on LINUXINCLUDE and explicit includes are thus removed. The format of the -I option differs between gcc and spatch. The COCCIINCLUDE is used to adapt the format. This rewritting needs bash.

* Add a target to use the Coccinelle checkerNicolas Palix2010-06-121-0/+54
A 'coccicheck' target is added. It can be called with four different modes. Each one generates a different kind of output, i.e. context, patch, org, report, according to the corresponding mode to be activated. The new target calls the 'coccicheck' front-end in the 'scripts' directory with the MODE argument. Every SmPL file in the subdirectories of 'scripts/coccinelle' is then given to the front-end and applied to the entire source tree. The four modes behave as follows: 'report' generates a list in the following format: file:line:column-column: message 'patch' proposes a fix, when possible. 'context' highlights lines of interest and their context in a diff-like style. Lines of interest are indicated with '-'. 'org' generates a report in the Org mode format of Emacs.
