get_maintainer: remove stray punctuation when cleaning file emails

2023-12-31T18:57:42Z

When parsing emails from .yaml files in particular, stray punctuation such as a leading '-' can end up in the name. For example, consider a common YAML section such as: maintainers: - devicetree@vger.kernel.org This would previously be processed by get_maintainer.pl as: - Make the logic in clean_file_emails more robust by deleting any sub-names which consist of common single punctuation marks before proceeding to the best-effort name extraction logic. The output is then correct: devicetree@vger.kernel.org Some additional comments are added to the function to make things clearer to future readers.

get_maintainer: correctly parse UTF-8 encoded names in files

2023-12-31T18:57:42Z

While the script correctly extracts UTF-8 encoded names from the MAINTAINERS file, the regular expressions damage my name when parsing from .yaml files. Fix this by replacing the Latin-1-compatible regular expressions with the unicode property matcher \p{L}, which matches on any letter according to the Unicode General Category of letters. The proposed solution only works if the script uses proper string encoding from the outset, so instruct Perl to unconditionally open all files with UTF-8 encoding. This should be safe, as the entire source tree is either UTF-8 or ASCII encoded anyway. See [1] for a detailed analysis. Furthermore, to prevent the \w expression from matching non-ASCII when checking for whether a name should be escaped with quotes, add the /a flag to the regular expression. The escaping logic was duplicated in two places, so it has been factored out into its own function. The original issue was also identified on the tools mailing list [2]. This should solve the observed side effects there as well.

kbuild: fix build ID symlinks to installed debug VDSO files

Commit 56769ba4b297 ("kbuild: unify vdso_install rules") accidentally dropped the '.debug' suffix from the build ID symlinks. Fixes: 56769ba4b297 ("kbuild: unify vdso_install rules") Signed-off-by: Masahiro Yamada

gen_compile_commands.py: fix path resolve with symlinks in it

2023-12-23T14:24:03Z

When a path contains relative symbolic links, os.path.abspath() might not follow the symlinks and instead return the absolute path with just the relative paths resolved, resulting in an incorrect path. 1. Say "drivers/hdf/" has some symlinks: # ls -l drivers/hdf/ total 364 drwxrwxr-x 2 ... 4096 ... evdev lrwxrwxrwx 1 ... 44 ... framework -> ../../../../../../drivers/hdf_core/framework -rw-rw-r-- 1 ... 359010 ... hdf_macro_test.h lrwxrwxrwx 1 ... 55 ... inner_api -> ../../../../../../drivers/hdf_core/interfaces/inner_api lrwxrwxrwx 1 ... 53 ... khdf -> ../../../../../../drivers/hdf_core/adapter/khdf/linux -rw-r--r-- 1 ... 74 ... Makefile drwxrwxr-x 3 ... 4096 ... wifi 2. One .cmd file records that: # head -1 ./framework/core/manager/src/.devmgr_service.o.cmd cmd_drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.o := ... \ /path/to/src/drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.c 3. os.path.abspath returns "/path/to/src/framework/core/manager/src/devmgr_service.c", not correct: # ./scripts/clang-tools/gen_compile_commands.py INFO: Could not add line from ./framework/core/manager/src/.devmgr_service.o.cmd: File \ /path/to/src/framework/core/manager/src/devmgr_service.c not found Use os.path.realpath(), which resolves the symlinks and normalizes the paths correctly. # cat compile_commands.json ... { "command": ... "directory": ... "file": "/path/to/bla/drivers/hdf_core/framework/core/manager/src/devmgr_service.c" }, ... Also fix it in parse_arguments(). Signed-off-by: Jialu Xu Signed-off-by: Masahiro Yamada

sign-file: Fix incorrect return values check

2023-12-13T20:55:11Z

There are some wrong return values check in sign-file when call OpenSSL API. The ERR() check cond is wrong because of the program only check the return value is < 0 which ignored the return val is 0. For example: 1. CMS_final() return 1 for success or 0 for failure. 2. i2d_CMS_bio_stream() returns 1 for success or 0 for failure. 3. i2d_TYPEbio() return 1 for success and 0 for failure. 4. BIO_free() return 1 for success and 0 for failure.

After the conversion to bus_to_subsys() and class_to_subsys(), the gdb scripts listing the system buses and classes respectively was broken, fix those by returning the subsys_priv pointer and have the various caller de-reference either the 'bus' or 'class' structure members accordingly.
