In checkpatch we attempt to check for and warn about
block comments which start with /* or /** followed by a
non-blank. Unfortunately a bug in the regex meant that
we would incorrectly warn about comments starting with
"/**" with no following text:
git show 9813dc6ac3954d58ba16b3920556f106f97e1c67|./scripts/checkpatch.pl -
WARNING: Block comments use a leading /* on a separate line
#34: FILE: tests/libqtest.h:233:
+/**
The sequence "/\*\*?" was intended to match either "/*" or "/**",
but Perl's semantics for '?' allow it to backtrack and try the
"matches 0 chars" option if the "matches 1 char" choice leads to
a failure of the rest of the regex to match. Switch to "/\*\*?+"
which uses what perlre(1) calls the "possessive" quantifier form:
this means that if it matches the "/**" string it will not later
backtrack to matching just the "/*" prefix.
The other end of the regex is also wrong: it is attempting
to check for "/* or /** followed by something that isn't
just whitespace", but [ \t]*.+[ \t]* will match on pure
whitespace. This is less significant but means that a line
with just a comment-starter followed by trailing whitespace
will generate an incorrect warning about block comment style
as well as the correct error about trailing whitespace which
a different checkpatch test emits.

We now require Linux-kernel-style multiline comments:

Enforce this in checkpatch.pl, by backporting the relevant

an extra argument that ours does not, and the kernel has a

The mechanism to find possible type tokens can sometimes be confused and go into an
infinite loop. This happens for example in QEMU for a line that looks like
uint## BITS ##_t S = _S, T = _T; \
uint## BITS ##_t as, at, xs, xt, xd; \
Because the token pasting operator does not have a space before _t, it does not
match $notPermitted. However, (?x) is turned on in the regular expression for
modifiers, and thus ##_t matches the empty string. As a result, annotate_values
goes in an infinite loop.
The solution is simply to remove token pasting operators from the string before
looking for modifiers. In the example above, the string uintBITS_t will be
evaluated as a candidate modifier. This is not optimal, but it works as long
as people do not write things like a##s##m, and it fits nicely into sub
possible.
For a similar reason, \# should be rejected always, even if it is not
at end of line or followed by whitespace.
The same patch was sent to the Linux kernel mailing list.

All the xen stable APIs define handle types of the form:
xen<subject of API>_handle
and some define additional handle types of the form:
xen<subject of API>_<purpose of handle>_handle
Examples of these are xenforeignmemory_handle and
xenforeignmemory_resource_handle.
Both of these types will be misparsed by checkpatch if they appear as the
first token in a line since, as types defined by an external library, they
do not conform to the QEMU CODING_STYLE, which suggests CamelCase.
A previous patch (5ac067a24a) added xendevicemodel_handle to the list
of types. This patch changes that to xen\w+_handle such that it will

Use of a loop construct for code that is not intended to repeat
does not make much idiomatic sense, except in one place: it is a
common usage in macros in order to wrap arbitrary code with
single-statement semantics. But when used in a macro, it is more
typical for the caller to supply the trailing ';' when calling
the macro.
Although qemu coding style frowns on bare:
if (cond)
statement1;
else
statement2;
where extra semicolons actually cause syntax errors, we still
want our macro styles to be easily copied to other projects.
Thus, declare it an error if we encounter any form of 'while (0)'
with a semicolon in the same line.

Currently before submitting a series, devs should run checkpatch.pl
across each patch to be submitted. This can be automated using a
command such as:
git rebase -i master -x 'git show | ./scripts/checkpatch.pl -'
This is rather long winded to type, so this patch introduces a way
to tell checkpatch.pl to validate a series of GIT revisions.
There are now three modes it can operate in 1) check a patch 2) check a source
file, or 3) check a git branch.
If no flags are given, the mode is determined by checking the args passed to
the command. If the args contain a literal ".." it is treated as a GIT revision
list. If the args end in ".patch" or equal "-" it is treated as a patch file.
Otherwise it is treated as a source file.
This automatic guessing can be overridden using --[no-]patch --[no-]file or
--[no-]branch
For example to check a GIT revision list:
$ ./scripts/checkpatch.pl master..
total: 0 errors, 0 warnings, 297 lines checked
b886d352a2bf58f0996471fb3991a138373a2957 has no obvious style problems and is ready for submission.
total: 0 errors, 0 warnings, 182 lines checked
2a731f9a9ce145e0e0df6d42dd2a3ce4dfc543fa has no obvious style problems and is ready for submission.
total: 0 errors, 0 warnings, 102 lines checked
11844169bcc0c8ed4449eb3744a69877ed329dd7 has no obvious style problems and is ready for submission.
If a genuine patch filename contains the characters '..' it is
possible to force interpretation of the arg as a patch
$ ./scripts/checkpatch.pl --patch master..
will force it to load a patch file called "master..", or equivalently
$ ./scripts/checkpatch.pl --no-branch master..
will simply turn off guessing of GIT revision lists.

Using signal to establish a signal handler is not portable; on
SysV systems, the signal handler would be reset to SIG_DFL after
delivery, while BSD preserves the signal handler. Daniel Berrange
reported that (to complicate matters further) the signal system call
has SysV behavior, but glibc signal() actually calls the sigaction
system call to provide BSD behavior.
However, using signal() to set a signal's disposition to SIG_DFL
or SIG_IGN is portable and is a relatively common occurrence in
QEMU source code, so allow that.

The default NetBSD package manager is pkgsrc and it installs Perl
along other third party programs under custom and configurable prefix.
The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.
This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.
This change switches -w option passed to the executable with more
modern "use warnings;" approach. There is no functional change to the
default behavior.

Glib commit a6a875068779 (from 2013) made many of the glib assert
macros non-fatal if a flag is set.
This causes two problems:
a) Compilers moan that your code is unsafe even though you've
put an assert in before the point of use.
b) Someone evil could, in a library, call
g_test_set_nonfatal_assertions() and cause our assertions in
important places not to fail and potentially allow memory overruns.
Ban most of the glib assertion functions (basically everything except
g_assert and g_assert_not_reached) except in tests/
This makes checkpatch gives an error such as:
ERROR: Use g_assert or g_assert_not_reached
#77: FILE: vl.c:4725:
+ g_assert_cmpstr("Chocolate", >, "Cheese");

Prevent blank lines in documentation code blocks to be signalled as
incorrect trailing whitespace.
Code blocks in documentation are 4-column aligned, and blank lines in
them should have exactly 4 columns of trailing whitespace to prevent
QEMU's wiki to render them as separate code blocks.

CHK-level checks have been removed from checkpatch or bumped to
errors, so there is no effect anymore for --strict/--subjective.
Furthermore, even most WARNs have been bumped to errors, with
WARN only reserved to things that patchew probably ought not
to complain about (and that maintainers probably will notice
anyway during review if they are extreme).
Default to exiting with success even if there are WARN-level
failures, and cause --strict to fail for warnings. Maintainers
that want to have a strict 80-character limit for their subsystem
can add it to a commit hook for example.
The --subjective synonym is removed.

This only leaves a warning-level message for the extra-long lines
soft limit. Everything else is bumped up.
In the future warnings can be added for checks that can have false
positives.
