Instead of using an unnecessarily complicated approach to print a line that is warned about, use `$herecurr` instead, just like everywhere else in checkpatch. While at it, remove a superfluous space in one of the changed lines, too. In a unmodified line also remove a superfluous check for a space before a signed-off-by tag, to me consistent with the check at the start of the section. All three problems were found by Joe Perches during review of new code inspired by the code modified here.

Encourage patch authors to link to reports by issuing a warning, if a Reported-by: is not accompanied by a link to the report. Those links are often extremely useful for any code archaeologist that wants to know more about the backstory of a change than the commit message provides. That includes maintainers higher up in the patch-flow hierarchy, which is why Linus asks developers to add such links [1, 2, 3]. To quote [1]: > Again, the commit has a link to the patch *submission*, which is > almost entirely useless. There's no link to the actual problem the > patch fixes. > > [...] > > Put another way: I can see that > > Reported-by:

I would want to > have an actual pointer to what they do and where. Another reason why these links are wanted: the ongoing regression tracking efforts can only scale with them, as they allow the regression tracking bot 'regzbot' to automatically connect tracked reports with patches that are posted or committed to fix tracked regressions.

Patch series "checkpatch.pl: warn about discouraged tags and missing Link: tags", v4. The first two changes make checkpatch.pl check for a few mistakes wrt to links to bug reports Linus recently complained about a few times. Avoiding those is also important for my regression tracking efforts a lot, as the automated tracking performed by regzbot relies on the proper usage of the Link: tag. The third patch fixes a few small oddities noticed in existing code during review of the two changes. This patch (of 3): Issue a warning when encountering URLs behind unknown tags, as Linus recently stated ```please stop making up random tags that make no sense. Just use "Link:"```[1]. That statement was triggered by an use of 'BugLink', but that's not the only tag people invented: $ git log -100000 --no-merges --format=email -P \ --grep='^\w+:[ ]*http' | grep -Poh '^\w+:[ ]*http' | \ sort | uniq -c | sort -rn | head -n 20 103958 Link: http 418 BugLink: http 372 Patchwork: http 280 Closes: http 224 Bug: http 123 References: http 84 Bugzilla: http 61 URL: http 42 v1: http 38 Datasheet: http 20 v2: http 9 Ref: http 9 Fixes: http 9 Buglink: http 8 v3: http 8 Reference: http 7 See: http 6 1: http 5 link: http 3 Link:http Some of these non-standard tags make it harder for external tools that rely on use of proper tags. One of those tools is the regression tracking bot 'regzbot', which looks out for "Link:" tags pointing to reports of tracked regressions. The initial idea was to use a disallow list to raise an error when encountering known unwanted tags like BugLink:; during review it was requested to use a list of allowed tags instead[2].

It was suggested by Fabio that kunmap() be marked deprecated in checkpatch.[1] This did not seem necessary until an invalid conversion of kmap_local_page() appeared in mainline.[2][3] The introduction of this bug would have been flagged with kunmap() being marked deprecated. Add kunmap() and kunmap_atomic() to checkpatch to help prevent further confusion.

checkpatch does not point out that VM_BUG_ON() and friends should be avoided, however, Linus notes: VM_BUG_ON() has the exact same semantics as BUG_ON. It is literally no different, the only difference is "we can make the code smaller because these are less important". [1] So let's warn on VM_BUG_ON() and other BUG variants as well. While at it, make it clearer that the kernel really shouldn't be crashed. As there are some subsystem BUG macros that actually don't end up crashing the kernel -- for example, KVM_BUG_ON() -- exclude these manually.

This enables the malformed SPDX check, the misplaced SPDX license tag check, the long line checks, the lines without a newline check and the embedded filename check. Reviewed-by:

kmap() and kmap_atomic() are being deprecated in favor of kmap_local_page(). There are two main problems with kmap(): (1) It comes with an overhead as mapping space is restricted and protected by a global lock for synchronization and (2) it also requires global TLB invalidation when the kmap's pool wraps and it might block when the mapping space is fully utilized until a slot becomes available. kmap_local_page() is safe from any context and is therefore redundant with kmap_atomic() with the exception of any pagefault or preemption disable requirements. However, using kmap_atomic() for these side effects makes the code less clear. So any requirement for pagefault or preemption disable should be made explicitly. With kmap_local_page() the mappings are per thread, CPU local, can take page faults, and can be called from any context (including interrupts). It is faster than kmap() in kernels with HIGHMEM enabled. Furthermore, the tasks can be preempted and, when they are scheduled to run again, the kernel virtual addresses are restored.

The code fragment below int foo(int *array, int index) { return array[index & 0xFF]; } triggers an incorrect camelcase detection by checking a substring of the hex constant: CHECK: Avoid CamelCase: <xFF> #3: FILE: test.c:3: + return array[index & 0xFF]; This is caused by passing the whole string "array[index & 0xFF]" to the inner loop that iterates over a "$Ident" match. The numeric constant is not a $Ident as it doesn't start with [A-Za-z_] and should be excluded from the match. Similar issue can be detected with other constants like "1uL", "0xffffU". Force the match to start at word boundary so the $Ident will be properly checked starting from its first char and the constants will be filtered-out.

Commit 0ee3e7b8 ("checkpatch: get default codespell dictionary path from package location") introduced the ability to search for the codespell dictionary rather than hardcoding its path. codespell requires Python 3.6 or above, but on some systems, the python executable is a Python 2.7 interpreter. In this case, searching for the dictionary fails, subsequently making codespell fail: No codespell typos will be found - file '/usr/share/codespell/dictionary.txt': No such file or directory So, use python3 to remove ambiguity. In addition, when searching for dictionary.txt, do not check if the codespell executable exists since, - checkpatch.pl only uses dictionary.txt, not the codespell executable. - codespell can be installed via a Python package manager, in which case the codespell executable may not be present in a typical $PATH, but a dictionary does exist.

One exceptions to the COMMIT_LOG_LONG_LINE rule is a file path followed by ':'. That is typically some sort diagnostic message from a compiler or a build tool, in which case we don't want to wrap the lines but keep the message unmodified.

GCC and Clang can use the "alloc_size" attribute to better inform the results of __builtin_object_size() (for compile-time constant values). Clang can additionally use alloc_size to inform the results of __builtin_dynamic_object_size() (for run-time values). Because GCC sees the frequent use of struct_size() as an allocator size argument, and notices it can return SIZE_MAX (the overflow indication), it complains about these call sites overflowing (since SIZE_MAX is greater than the default -Walloc-size-larger-than=PTRDIFF_MAX). This isn't helpful since we already know a SIZE_MAX will be caught at run-time (this was an intentional design). To deal with this, we must disable this check as it is both a false positive and redundant. (Clang does not have this warning option.) Unfortunately, just checking the -Wno-alloc-size-larger-than is not sufficient to make the __alloc_size attribute behave correctly under older GCC versions. The attribute itself must be disabled in those situations too, as there appears to be no way to reliably silence the SIZE_MAX constant expression cases for GCC versions less than 9.1: In file included from ./include/linux/resource_ext.h:11, from ./include/linux/pci.h:40, from drivers/net/ethernet/intel/ixgbe/ixgbe.h:9, from drivers/net/ethernet/intel/ixgbe/ixgbe_lib.c:4: In function 'kmalloc_node', inlined from 'ixgbe_alloc_q_vector' at ./include/linux/slab.h:743:9: ./include/linux/slab.h:618:9: error: argument 1 value '18446744073709551615' exceeds maximum object size 9223372036854775807 [-Werror=alloc-size-larger-than=] return __kmalloc_node(size, flags, node); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/linux/slab.h: In function 'ixgbe_alloc_q_vector': ./include/linux/slab.h:455:7: note: in a call to allocation function '__kmalloc_node' declared here void *__kmalloc_node(size_t size, gfp_t flags, int node) __assume_slab_alignment __malloc; ^~~~~~~~~~~~~~ Specifically: '-Wno-alloc-size-larger-than' is not correctly handled by GCC < 9.1 https://godbolt.org/z/hqsfG7q84 (doesn't disable) https://godbolt.org/z/P9jdrPTYh (doesn't admit to not knowing about option) https://godbolt.org/z/465TPMWKb (only warns when other warnings appear) '-Walloc-size-larger-than=18446744073709551615' is not handled by GCC < 8.2 https://godbolt.org/z/73hh1EPxz (ignores numeric value) Since anything marked with __alloc_size would also qualify for marking with __malloc, just include __malloc along with it to avoid redundant markings. (Suggested by Linus Torvalds.) Finally, make sure checkpatch.pl doesn't get confused about finding the __alloc_size attribute on functions. (Thanks to Joe Perches.)

Although the local-part of an email address (local-part@domain), may be case sensitive, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged. Mailbox domains follow normal DNS rules and are hence not case sensitive. (Refer to https://datatracker.ietf.org/doc/html/rfc5321#section-2.4.) Further relax the patch author and signed-off-by tag comparison by making the email address check case insensitive.

checkpatch complains about positive return values of poll functions. Example: WARNING: return of an errno should typically be negative (ie: return -EPOLLIN) + return EPOLLIN; Poll functions return positive values. The defines for the return values of poll functions all start with EPOLL, resulting in a number of false positives. An often used workaround is to assign poll function return values to variables and returning that variable, but that is a less than perfect solution. There is no error definition which starts with EPOLL, so it is safe to omit the warning for return values starting with EPOLL.

checkpatch identifies a label only when a terminating colon immediately follows an identifier. Bitfield definitions can appear to be labels so ignore any spaces between the identifier terminating colon and any digit that may be used to define a bitfield length. Miscellanea: o Improve the initial checkpatch comment o Use the more typical '&&' instead of 'and' o Require the initial label character to be a non-digit (Can't use $Ident here because $Ident allows ## concatenation) o Use $sline instead of $line to ignore comments o Use '$sline !~ /.../' instead of '!($line =~ /.../)' Link: https://lkml.kernel.org/r/b54d673e7cde7de5de0c9ba4dd57dd0858580ca4.camel@perches.com Signed-off-by:

Since commit d0259c42 ("spdxcheck.py: Use Python 3"), spdxcheck.py explicitly expects to run as python3 script. If "python" still points to python v2.7 and the script is executed with "python scripts/spdxcheck.py", the following error may be seen even if git-python is installed for python3. Traceback (most recent call last): File "scripts/spdxcheck.py", line 10, in <module> import git ImportError: No module named git To fix the problem, check for the existence of python3, check if the script is executable and not just for its existence, and execute it directly.

__must_be_array, offsetof, sizeof_field and __stringify are all preprocessor macros and do not evaluate their arguments. As such, it is safe not to warn when arguments are being reused in those four sub-expressions. Exclude those so that they can pass checkpatch.

Add a new verbose mode to checkpatch.pl to emit additional verbose test descriptions. The verbose mode is optional and can be enabled by the flag -v or --verbose. The test descriptions are parsed from the checkpatch documentation file at `Documentation/dev-tools/checkpatch.rst`. The test descriptions in the docs are kept in a fixed format grouped by usage. Some examples of this format are: **LINE_SPACING** Vertical space is wasted given the limited number of lines an editor window can display when multiple blank lines are used. **MISSING_SIGN_OFF** The patch is missing a Signed-off-by line. A signed-off-by line should be added according to Developer's certificate of Origin. To avoid lengthy output, the verbose description is printed only for the first instance of a particular message type. The --verbose option cannot be used along with the --terse option. Verbose mode can be used with the --list-types option. The --list-types output also supports color coding now. Signed-off-by:
