checkpatch: fix incorrect camelcase detection on numeric constant

2022-06-17T02:58:22+00:00

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: #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.

checkpatch: add XA_STATE and XA_STATE_ORDER to the macro declaration list

2022-06-17T02:58:19+00:00

XA_STATE() and XA_STATE_ORDER macro uses are declarations. Add them to the declaration macro list to avoid suggesting a blank line after declarations when used.

scripts: checkpatch: enable language-independent checks for Rust

2022-05-23T00:24:55+00:00

Include Rust in the "source code files" category, so that the language-independent tests are checked for Rust too, and teach `checkpatch` about the comment style for Rust files. 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.

scripts: checkpatch: diagnose uses of `%pA` in the C side

2022-05-23T00:24:55+00:00

The `%pA` format specifier is only intended to be used from Rust. `checkpatch.pl` already gives a warning for invalid specificers: WARNING: Invalid vsprintf pointer extension '%pA' With this change, we introduce an error message with further explanation: ERROR: '%pA' is only intended to be used from Rust code Suggested-by: Kees Cook Co-developed-by: Alex Gaynor Signed-off-by: Alex Gaynor Co-developed-by: Wedson Almeida Filho Signed-off-by: Wedson Almeida Filho Signed-off-by: Miguel Ojeda

checkpatch: add new alloc functions to alloc with multiplies check

2022-04-26T06:30:33+00:00

kvmalloc() and kvzalloc() functions have now 2-factor multiplication argument forms kvmalloc_array() and kvcalloc(), correspondingly. Add alloc-with-multiplies checks for these new functions. Link: https://github.com/KSPP/linux/issues/187 Signed-off-by: Gustavo A. R. Silva

checkpatch: use python3 to find codespell dictionary

2022-03-24T02:00:34+00:00

Commit 0ee3e7b8893e ("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.

checkpatch: add early_param exception to blank line after struct/function test

2022-03-24T02:00:34+00:00

Add early_param as another exception to the blank line preferred after function/struct/union declaration or definition test.

checkpatch: add --fix option for some TRAILING_STATEMENTS

2022-03-24T02:00:34+00:00

Single line code like: if (foo) bar; should generally be written: if (foo) bar; Add a --fix test to do so. This fix is not done when an ASSIGN_IN_IF in the same line exists.
