kconfig/nconf: Initialize the default locale at startup

2025-12-06T21:12:39+00:00

[ Upstream commit 43c2931a95e6b295bfe9e3b90dbe0f7596933e91 ]

Fix bug where make nconfig doesn't initialize the default locale, which
causes ncurses menu borders to be displayed incorrectly (lqqqqk) in
UTF-8 terminals that don't support VT100 ACS by default, such as PuTTY.

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

2025-08-28T14:26:02+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.

kconfig: gconf: avoid hardcoding model2 in on_treeview2_cursor_changed()

2025-08-28T14:26:02+00:00

[ Upstream commit cae9cdbcd9af044810bcceeb43a87accca47c71d ]

The on_treeview2_cursor_changed() handler is connected to both the left
and right tree views, but it hardcodes model2 (the GtkTreeModel of the
right tree view). This is incorrect. Get the associated model from the
view.

kconfig: nconf: Ensure null termination where strncpy is used

2025-08-28T14:26:02+00:00

[ Upstream commit f468992936894c9ce3b1659cf38c230d33b77a16 ]

strncpy() does not guarantee null-termination if the source string is
longer than the destination buffer.

Ensure the buffer is explicitly null-terminated to prevent potential
string overflows or undefined behavior.

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

2025-08-28T14:26:02+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.

kconfig: qconf: fix ConfigList::updateListAllforAll()

[ Upstream commit 721bfe583c52ba1ea74b3736a31a9dcfe6dd6d95 ]

ConfigList::updateListForAll() and ConfigList::updateListAllforAll()
are identical.

Commit f9b918fae678 ("kconfig: qconf: move ConfigView::updateList(All)
to ConfigList class") was a misconversion.

kconfig: merge_config: use an empty file as initfile

2025-06-04T12:40:02+00:00

[ Upstream commit a26fe287eed112b4e21e854f173c8918a6a8596d ]

The scripts/kconfig/merge_config.sh script requires an existing
$INITFILE (or the $1 argument) as a base file for merging Kconfig
fragments. However, an empty $INITFILE can serve as an initial starting
point, later referenced by the KCONFIG_ALLCONFIG Makefile variable
if -m is not used. This variable can point to any configuration file
containing preset config symbols (the merged output) as stated in
Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will
contain just the merge output requiring the user to run make (i.e.
KCONFIG_ALLCONFIG=<$INITFILE> make  or make
olddefconfig).

Instead of failing when `$INITFILE` is missing, create an empty file and
use it as the starting point for merges.

kconfig: fix memory leak in sym_warn_unmet_dep()

The string allocated in sym_warn_unmet_dep() is never freed, leading
