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. For example, run the following:
$ make V=1 COCCI=scripts/coccinelle/free/kfree.cocci coccicheck
[ snip ]
The semantic patch that makes this report is available
in scriptcoccinelle/free/kfree.cocci.
Notice "s/" was dropped from "scripts/coccinelle/free/kfree.cocci".
When running coccicheck without O=, $srctree is expanded to ".", which
represents one arbitrary character in the regular expression. Using
sed is not a good choice here. Strip $srctree/ simply without sed.

Currently, the required version for badzero.cocci is picked up from
its "Comments:" line since it contains the word "Requires".
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. I removed "-rc20"
because ld-version.sh cannot handle it.
Make the coccicheck script to see exact patterns for "Options:" and
"Requires:" in order to avoid accidental matching to what just happens
to appear in comment lines.

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.

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.

Enable Coccinelle SmPL patches to require a specific version of
Coccinelle. In the event that the version does not match we just
inform the user, if the user asked to go through all SmPL patches
we just inform them of the need for a new version of coccinelle for
the SmPL patch and continue on with the rest.
This uses the simple kernel scripts/ld-version.sh to create a weight
on the version provided by spatch. The -dirty attribute is ignored if
supplied, the benefit of scripts/ld-version.sh is it has a long history
and well tested.

Enable to capture stderr via a DEBUG_FILE variable passed to
coccicheck. You can now do:
$ rm -f cocci.err
$ export COCCI=scripts/coccinelle/free/kfree.cocci
$ make coccicheck MODE=report DEBUG_FILE=cocci.err
...
$ cat cocci.err
This will be come more useful once we add support to
use more things which would go into stderr, such as
profiling. That will be done separately in another
commit.

Coccinelle has had parmap support since 1.0.2, this means
it supports --jobs, enabling built-in multithreaded functionality,
instead of needing one to script it out. 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

SPFLAGS is set early, it means that any heuristics done on
coccicheck cannot be overridden currently. Move SPFLAGS
after OPTIONS and set this at the end. This lets you override
any heuristics as coccinelle treats conflicts by only listening

Documentation/coccinelle.txt suggests using the SPFLAGS
make variable to pass additional options to spatch.
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.

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.
