kconfig: lxdialog: fix 'space' to (de)select options

2025-08-28T14:28:29+00:00

[ Upstream commit 694174f94ebeeb5ec5cc0e9de9b40c82057e1d95 ] In case a menu has comment without letters/numbers (eg. characters matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *), hitting space will cycle through those comments, rather than selecting/deselecting the currently-highlighted option. This is the behaviour of hitting any letter/digit: jump to the next option which prompt starts with that letter. The only letters that do not behave as such are 'y' 'm' and 'n'. Prompts that start with one of those three letters are instead matched on the first letter that is not 'y', 'm' or 'n'. Fix that by treating 'space' as we treat y/m/n, ie. as an action key, not as shortcut to jump to prompt. Signed-off-by: Yann E.

kconfig: lxdialog: replace strcpy() with strncpy() in inputbox.c

2025-08-28T14:28:29+00:00

[ Upstream commit 5ac726653a1029a2eccba93bbe59e01fc9725828 ] strcpy() performs no bounds checking and can lead to buffer overflows if the input string exceeds the destination buffer size. This patch replaces it with strncpy(), and null terminates the input string. Signed-off-by: Suchit Karunakaran Reviewed-by: Nicolas Schier Signed-off-by: Masahiro Yamada Signed-off-by: Sasha Levin

kconfig: menuconfig: simplify global jump key assignment

2023-07-24T15:59:32+00:00

Commit 95ac9b3b585d ("menuconfig: Assign jump keys per-page instead of globally") injected a lot of hacks to the bottom of the textbox infrastructure. I reverted many of them without changing the behavior. (almost) Now, the key markers are inserted when constructing the search result instead of updating the text buffer on-the-fly. The buffer passed to the textbox got back to a constant string. The ugly casts from (const char *) to (char *) went away. A disadvantage is that the same key numbers might be displayed multiple times in the dialog if you use a huge window (but I believe it is unlikely to happen).

kconfig: menuconfig: reorder functions to remove forward declarations

2023-04-17T02:03:56+00:00

Define helper functions before the callers so that forward declarations can go away. Signed-off-by: Masahiro Yamada

kconfig: remove trailing whitespaces

There are still some trailing whitespaces under scripts/kconfig/tests/, but they must be kept. Otherwise, "make testconfig" would break. Signed-off-by: Masahiro Yamada

kconfig/[mn]conf: handle backspace (^H) key

2019-03-29T13:48:01+00:00

Backspace is not working on some terminal emulators which do not send the key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127). But currently only '^?' is handled. Let's also handle '^H' for those terminals. Signed-off-by: Changbin Du Signed-off-by: Masahiro Yamada

kconfig: remove stale lxdialog/.gitignore

2019-03-17T06:47:02+00:00

When this .gitignore was added, lxdialog was an independent hostprogs-y. Now that all objects in lxdialog/ are directly linked to mconf, the lxdialog is no longer generated. Signed-off-by: Masahiro Yamada
