kconfig: fix memory leak in sym_warn_unmet_dep()

2025-01-29T23:43:12Z

The string allocated in sym_warn_unmet_dep() is never freed, leading to a memory leak when an unmet dependency is detected. Fixes: f8f69dc0b4e0 ("kconfig: make unmet dependency warnings readable") Signed-off-by: Masahiro Yamada Reviewed-by: Petr Vorel

kconfig: fix file name in warnings when loading KCONFIG_DEFCONFIG_LIST

2025-01-29T23:40:17Z

Most 'make *config' commands use .config as the base configuration file. When .config does not exist, Kconfig tries to load a file listed in KCONFIG_DEFCONFIG_LIST instead. However, since commit b75b0a819af9 ("kconfig: change defconfig_list option to environment variable"), warning messages have displayed an incorrect file name in such cases. Below is a demonstration using Debian Trixie. While loading /boot/config-6.12.9-amd64, the warning messages incorrectly show .config as the file name. With this commit, the correct file name is displayed in warnings. [Before] $ rm -f .config $ make config # # using defaults found in /boot/config-6.12.9-amd64 # .config:6804:warning: symbol value 'm' invalid for FB_BACKLIGHT .config:9895:warning: symbol value 'm' invalid for ANDROID_BINDER_IPC [After] $ rm -f .config $ make config # # using defaults found in /boot/config-6.12.9-amd64 # /boot/config-6.12.9-amd64:6804:warning: symbol value 'm' invalid for FB_BACKLIGHT /boot/config-6.12.9-amd64:9895:warning: symbol value 'm' invalid for ANDROID_BINDER_IPC Fixes: b75b0a819af9 ("kconfig: change defconfig_list option to environment variable") Signed-off-by: Masahiro Yamada

kconfig: qconf: use preferred form of QString API

2025-01-10T14:01:22Z

A QString constructed from a character literal of length 0, i.e. "", is not "null" for historical reasons. This does not matter here so use the preferred method isEmpty() instead. Also directly construct empty QString objects instead of passing in an empty character literal that has to be parsed into an empty object first.

kbuild: suppress stdout from merge_config for silent builds

2025-01-10T14:01:21Z

merge_config does not respect the Make's -s (--silent) option. Let's sink the stdout from merge_config for silent builds. This commit does not cater to the direct invocation of merge_config.sh (e.g. arch/mips/Makefile).

kconfig: qconf: remove unnecessary mode check in ConfigItem::updateMenu()

2024-11-05T23:46:34Z

The P_MENU entries ("menu" and "menuconfig") are never displayed in symbolMode. The condition, list->mode == symbolMode, is never met here. Signed-off-by: Masahiro Yamada

kconfig: qconf: refactor ConfigInfoView::clicked()

2024-11-05T23:46:34Z

Most of the code in ConfigInfoView::clicked() is unnecessary. There is no need to use the regular expression to search for a symbol. Calling sym_find() is simpler and faster. The hyperlink always begins with the "s" tag, and there is no other tag used. Remove it. Signed-off-by: Masahiro Yamada

kconfig: add sym_get_prompt_menu() helper function

2024-11-05T23:46:34Z

Split out the code that retrieves the menu entry with a prompt, so it can be reused in other functions. Signed-off-by: Masahiro Yamada

kconfig: qconf: remove non-functional href="m..." tag

2024-11-05T23:46:34Z

The only functional tag is href="s". Commit c4f7398bee9c ("kconfig: qconf: make debug links work again") changed prop->name to sym->name for this reference, but it missed to change the tag "m" to "s". This tag is not functional at all. Signed-off-by: Masahiro Yamada
