OpenCV probes the host compiler for LSX/LASX by trying to compile a
small test program with '-mlsx' / '-mlasx'. With Buildroot's toolchain
this probe succeeds even when the target CPU lacks the matching ISA
extension, and the resulting libraries then contain LSX/LASX
instructions. This causes SIGILL at runtime on, e.g., the LA264.
Map Buildroot's BR2_LOONGARCH_SIMD_* selection to OpenCV's
CPU_BASELINE / CPU_DISPATCH knobs:
BR2_LOONGARCH_SIMD_NONE -> no baseline, no dispatch
BR2_LOONGARCH_SIMD_LSX -> baseline = LSX, no dispatch
BR2_LOONGARCH_SIMD_LASX -> baseline = LSX, dispatch = LASX
The block is gated on BR2_loongarch64, so the existing auto detection
remains in effect for every other architecture.

All Qt6 packages install their own SPDX SBOM in
$(TARGET_DIR)/usr/lib/qt6/sbom/. In the context of Buildroot having
such SBOMs on the target is not useful, and they take up some space,
so get rid of them.
We use a TARGET_FINALIZE_HOOKS (and not a POST_INSTALL_TARGET_HOOKS)
because it's not just qt6base that installs SBOMs, but all qt6
modules, so we want the cleanup to happen after they all got
installed.

iconv types are defined differently in glibc (as pointers) and uclibc
(as integers). With changes in GCC14, -Wint-conversion has now become
an error, which shed some light on the issue.
The actual fix for that problem is released in uclibc 1.0.58 [1].
However, because these type definitions are in toolchain headers,
this means that the toolchain used to build samba must also include
uclibc>=1.0.58 (either an external toolchain that includes the uclibc fix,
or a Buildroot toolchain after the uclibc fix is merged in Buildroot [2]).
Until then, provide a workaround for samba itself.
No autobuilder failure on this (yet). It can be reproduced with

Buildroot added the bpftrace package in 2024 with commit
338acb27ff
which initially provided version 0.19.1.
This release includes upstream commit
fea3193989
which was added to version 0.17.0 in 2022 and makes use of certain
variables of struct bpf_btf_info which were added to the linux kernel in
2020 with version 5.11:
5329722057
+ __aligned_u64 name;
+ __u32 name_len;
+ __u32 kernel_btf;
The libbpf package updates toolchain headers with its bundled version
only when the toolchain headers are version 5.8 or older, this condition
is part of the initial version of the package added in 2020 with
buildroot commit f7b8508e4f. This version
limit should have been raised when the bpftrace package was added to
avoid build errors when the toolchain contains header versions 5.9 or
5.10.
This situation caused build errors in the autobuilder, the last one in
February 2025:
/home/autobuild/autobuild/instance-18/output-1/build/bpftrace-0.19.1/src/bpffeature.cpp:
In member function 'bool bpftrace::BPFfeature::has_module_btf()':

574 | info.name_len = sizeof(name);
The problem disappeared from the autobuilders due to newer headers
versions used for the buildroot toolchain or other build errors occurring
earlier, like llvm version mismatches.
The build error can today still be reproduced with this defconfig
BR2_aarch64=y

libbpf overwrites kernel header files installed in $STAGING_DIR when
they are too old by adding 'install_uapi_headers' as make target. In
the case of per-package directories these header files are stored only
in output/per-package/libbpf/.
When output/per-package/bpftrace/ is populated, the content of
output/per-package/ from other packages overwrites the header files
installed by libbpf because the list of rsync'ed packages is sorted
alphabetically:
https://gitlab.com/buildroot.org/buildroot/-/blob/2026.02.1/package/pkg-generic.mk#L796
To prevent this problem let libbpf install the updated kernel headers in
a new directory.
Other packages need to find this directory. This mostly happens through
pkg-config, but bpftrace doesn't use that:
https://github.com/bpftrace/bpftrace/blob/v0.25.1/cmake/FindLibBpf.cmake#L9
Therefore, use a configure option in bpftrace to set the correct path.
Please note that libbpf will add '/linux' to the path provided in
$UAPIDIR:
https://github.com/libbpf/libbpf/blob/v1.7.0/src/Makefile#L169
so the headers end up in the previously non-existing directory

bpf.h with 283012 bytes is the update-to-date version needed for bpftrace:
$ grep -m1 bpf_iter_link_info output/per-package/libbpf/host/x86_64-buildroot-linux-gnu/sysroot/usr/include/bpf/linux/bpf.h
union bpf_iter_link_info {
$
$ grep -m1 bpf_iter_link_info output/per-package/libbpf/host/x86_64-buildroot-linux-gnu/sysroot/usr/include/linux/bpf.h
$
By adding '-I$(STAGING_DIR)/usr/include/bpf' to the CXXFLAGS of bpftrace
its include finds the correct header:
https://github.com/bpftrace/bpftrace/blob/v0.25.1/src/bpfprogram.cpp#L3
#include <linux/bpf.h>
The dpdk package uses pkg-config` to detect libbpf and will use the updated
.pc file:
https://github.com/DPDK/dpdk/blob/v25.11/drivers/net/tap/bpf/meson.build#L7
The iproute2 package is not affected by the problem because it contains
"matching sanitized kernel headers":
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/tree/README?h=v6.17.0#n44
As a host package pahole is also not affected.

Since last commit, utils/generate-cyclonedx can now be used with
Buildroot host tools, provided the user either externally install the
SPDX schema in the DL_DIR themselves or have
BR2_PACKAGE_HOST_PYTHON3_SSL and BR2_PACKAGE_HOST_CA_CERTIFICATES both
enabled. If the latter is missing, Python will complain with:

It's quite confusing really but what it means is that host Python was
built without ssl support.
This adds an additional check importing _ssl and if the module is not
found, tell the user what to do. This still doesn't make Buildroot's
host Python3 fully usable for utils/generate-cyclonedx as it'll then
fail when trying to validate certificates, this will be handled in the
next few commits.
Note that ssl Python library is always built in CPython, but itself
imports the _ssl module which is the one that may be disabled with
py_cv_module__ssl=n/a (which is what happens when
BR2_PACKAGE_HOST_PYTHON3_SSL is not enabled), hence why _ssl is checked
and not ssl.

Buildroot-local patches can only be suffixed by .patch, otherwise they
either need to be downloaded via <PKG>_PATCH or manually applied via
$(APPLY_PATCHES) in a <PKG>_{PRE,POST}_PATCH_HOOKS like in
linux/linux.mk. In the former case, they are then listed in the
show-info output with a full URL (prefixed by '<PKG>_SITE_METHOD+'). In
the latter case, they not listed as patches at the moment, just as
externalReferences.
By removing "support" for those compressed patches, we can avoid the bz2
dependency and can now use Buildroot's host-python3 package without
BR2_PACKAGE_HOST_PYTHON3_BZIP2 to run utils/generate-cyclonedx.

Some packages do not have a http/https download URL for a source tarball,
but are acquired over a version control system like git. If so, add
externalReferences of type "vcs" for such URLs.
As most git repositories use a https:// transport that may not indicated the
repository type, add a "comment" due to the lack of a better mechanism in
CycloneDX.
While the hashes are calculated over a tarball created locally, it still may
be useful, so add them for "vcs" externalReferences as well.

Finding the hash file for a package is non-trivial, as they can be in a
<version> sub-directory or under GLOBAL_PATCH_DIR. To allow other tools
such as utils/generate-cyclonedx to find hash files, expose this information
from show-info. If a package does not provide a hash file, create an
empty hashes array.

Commit dc4af8bfa9 ("utils/generate-cyclonedx: use direct dependencies")
removes indirect dependencies from any listed component, as required by
CycloneDX. The root component, however, still includes indirect dependencies,
as it just takes the components from the show-info output.
Fix this by collecting all component dependencies, and then filter the root
component dependencies to include direct dependencies only.
