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

[ 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

[ 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.

kbuild: Add KBUILD_CPPFLAGS to as-option invocation

2025-06-27T10:07:24+00:00

commit 43fc0a99906e04792786edf8534d8d58d1e9de0c upstream.

After commit feb843a469fb ("kbuild: add $(CLANG_FLAGS) to
KBUILD_CPPFLAGS"), there is an error while building certain PowerPC
assembly files with clang:

  arch/powerpc/lib/copypage_power7.S: Assembler messages:
  arch/powerpc/lib/copypage_power7.S:34: Error: junk at end of line: `0b01000'
  arch/powerpc/lib/copypage_power7.S:35: Error: junk at end of line: `0b01010'

  arch/powerpc/lib/copypage_power7.S:40: Error: junk at end of line: `0b01010'
  clang: error: assembler command failed with exit code 1 (use -v to see invocation)

as-option only uses KBUILD_AFLAGS, so after removing CLANG_FLAGS from
KBUILD_AFLAGS, there is no more '--target=' or '--prefix=' flags. As a
result of those missing flags, the host target
will be tested during as-option calls and likely fail, meaning necessary
flags may not get added when building assembly files, resulting in
errors like seen above.

Add KBUILD_CPPFLAGS to as-option invocations to clear up the errors.
This should have been done in commit d5c8d6e0fa61 ("kbuild: Update
assembler calls to use proper flags and language target"), which
switched from using the assembler target to the assembler-with-cpp
target, so flags that affect preprocessing are passed along in all
relevant tests. as-option now mirrors cc-option.

kbuild: add $(CLANG_FLAGS) to KBUILD_CPPFLAGS

2025-06-27T10:07:24+00:00

commit feb843a469fb0ab00d2d23cfb9bcc379791011bb upstream.

When preprocessing arch/*/kernel/vmlinux.lds.S, the target triple is
not passed to $(CPP) because we add it only to KBUILD_{C,A}FLAGS.

As a result, the linker script is preprocessed with predefined macros
for the build host instead of the target.

Assuming you use an x86 build machine, compare the following:

 $ clang -dM -E -x c /dev/null
 $ clang -dM -E -x c /dev/null -target aarch64-linux-gnu

There is no actual problem presumably because our linker scripts do not
rely on such predefined macros, but it is better to define correct ones.

Move $(CLANG_FLAGS) to KBUILD_CPPFLAGS, so that all *.c, *.S, *.lds.S
will be processed with the proper target triple.

[Note]
After the patch submission, we got an actual problem that needs this
commit. (CBL issue 1859)

kbuild: Add CLANG_FLAGS to as-instr

2025-06-27T10:07:24+00:00

commit cff6e7f50bd315e5b39c4e46c704ac587ceb965f upstream.

A future change will move CLANG_FLAGS from KBUILD_{A,C}FLAGS to
KBUILD_CPPFLAGS so that '--target' is available while preprocessing.
When that occurs, the following errors appear multiple times when
building ARCH=powerpc powernv_defconfig:

  ld.lld: error: vmlinux.a(arch/powerpc/kernel/head_64.o):(.text+0x12d4): relocation R_PPC64_ADDR16_HI out of range: -4611686018409717520 is not in [-2147483648, 2147483647]; references '__start___soft_mask_table'

Diffing the .o.cmd files reveals that -DHAVE_AS_ATHIGH=1 is not present
anymore, because as-instr only uses KBUILD_AFLAGS, which will no longer
contain '--target'.

Mirror Kconfig's as-instr and add CLANG_FLAGS explicitly to the
invocation to ensure the target information is always present.

randstruct: gcc-plugin: Fix attribute addition
