The maintenance and testing workflow sometimes requires to output a
list of every existing package on Buildroot:
- Generating an SBOM of the whole Buildroot tree, e.g. `for
security.buildroot.org
- List every source for every package, e.g. for sources.buildroot.net
The previous solution relied on `make allyesconfig` but always ran into
conflicts that needed manual resolution. Also some packages would not be
present because they are architecture dependent.
To avoid having to manually modify the 'show-info' command this commit
adds the 'show-info-all' command. It accesses the PACKAGES_ALL variable
with all the packages present in Buildroot independently of the
architecture or any config entries.
It forces the `BR2_HAVE_DOT_CONFIG` variable to be set to force the
reading of the package mk files.
It is also added to noconfig_targets, to avoid the .config influencing
the output of show-info-all.
Note that this is not yet a complete solution - it doesn't take into
account the multiple versions that are possible for some packages like
GCC. Also for e.g. linux or uboot the version is empty and the URL is
invalid.

Specifying a list of br2-external trees is poorly documented, and the
only example uses a colon to separate the br2-external paths.
Adding the support for colon-separated list is the biggest mistake that
was made when introducing support for multiple br2-external [0]. Indeed,
both space and colon can be used to separate entries in the list, and it
is also possible to mix the two. However, internally, the list is stored
as a space-separated list, and all the code will split on spaces.
Besides, all other lists in Buildroot are a space-separated:
BR2_ROOTFS_DEVICE_TABLE
BR2_ROOTFS_STATIC_DEVICE_TABLE
BR2_TARGET_TZ_ZONELIST
BR2_ROOTFS_USERS_TABLES
BR2_ROOTFS_OVERLAY
BR2_ROOTFS_PRE_BUILD_SCRIPT
BR2_ROOTFS_POST_BUILD_SCRIPT
BR2_ROOTFS_POST_FAKEROOT_SCRIPT
BR2_ROOTFS_POST_IMAGE_SCRIPT
...
So, using colons is odd.
The fact that BR2_EXTERNAL is passed on the command line rather than
being a Kconfig item is not a reason enough to justify that it be
colon-separated.
Change the documentation to only mention using a space-separated list.
Of course, for backward compatibility, we keep the code as-is to accept
a colon-separated list, but we just do not advertise it.
Note that keeping the split on colons means that colons are not accepted
in pathnames of br2-external trees; in practice, this is not a new
restriction, or one that could lift as usign colons in Makefiles are
problematic anyway.

The network-manager package currently pulls in either gnutls or libnss,
neither of which are very common and it might be the only reason why
they are present on a system.
However, most of NetworkManager works just fine without any cryptography
support, it only seems to be used in test cases and 802.1X support code.
Remove the dependency but use a library if it is present.
Note that this changes the default behavior. If network-manager was the
only package pulling in gnutls, it won't do this anymore and use the
"null" backend. Add a note about this to the manual.

This patch adds information on how to provides static JS libraries in
Buildroot with the release of the 2025.08.x version.
Because the way JavaScript project development is working the chances that your
project is using the same version of the buildroot package, and you provide
this library from `/var/www` to your users is actually really low ...
If you want to bundle JavaScript libraries in your project you should probably
either use a cdn, handle the package version and location of your choice in
your external or overlay, or just bundle it in your assets from a NPM workflow
to benefit from some minifications from your bundler.
Historically many of those JavaScript libraries were added in the 2010 eras
where it could make sense for them to be part of Buildroot.
Most of them are also way outdated/not maintained.

Currently, when a golang package defines multiple _BUILD_TARGETS, it has
to basically repeat the same list in its _INSTALL_BINS.
When a golang package defines multiple _BUILD_TARGETS, the pkg-golang
infra will forcibly use the basename (the notdir) of each target as the
name of the generated binary; there is no option to set a per-target
binary name.
However, the pkg-golang infra by default tries to install a binary named
after the package rawname. This forces packages to basically repeat the
same list as their _BUILD_TARGETS to override _INSTALL_BINS, when the
list of generated binaries is already known to the infra.
We change the pkg-golang infra to better cover such a case:
- if _BUILD_TARGET is '.' (the default), keep the current scheme:
install a single binary named after the package rwaname;
- if _BUILD_TARGET is not '.', and contains a single word, use the
notdir of the built target, but allow the user to override it with
_BIN_NAME (the current behaviour);
- otherwise (_BUILD_TARGETS is set to more than one word), do not
allow the user to set _BIN_NAME (it does not make sense), but set
_INSTALL_BINS by default to the notdir of _BUILD_TARGETS.
We still allow the user to set _INSTALL_BINS in the last case, to cover
the case for existing packages; those are going to be "fixed" in the
following commits.
We now consider that _INSTALL_BINS is an internal implementation details
that should no longer be exposed to the users, so we drop it from the
documentation; we rephrase the corresponding part for _BUILD_TARGETS.

Buildroot packaging pretty much assumes that the sources it downloads
are publicly available. In general, however, Buildroot is also used to
download sources from private repositories. Nowadays, that mostly means
from a github or gitlab instance.
Although git-over-ssh can be used for that, this poses a problem for CI,
because the CI runners integrated with github and gitlab only have
access to the repository itself, not to other private repositories. And
creating ssh key pairs for CI runners is tricky.
Therefore, document how standard tools can be used to make private
repositories available both to developers and to CI. There are quite a
few alternative approaches possible, but they're more complicated or
less generically applicable.

A basic Fedora 42 container does not have 'awk' installed, but it is
needed by Buildroot. First by check-host-python3.sh:
support/dependencies/check-host-python3.sh: line 6: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
but then even building host-expat assumes awk is available:
config.status: creating Makefile
./config.status: line 1404: awk: command not found
config.status: creating expat.pc
./config.status: line 1404: awk: command not found
Since it's a pretty basic tool, make it part of the tools checked by
dependencies.sh. One minor annoyance is that check-host-python3.sh is
executed *before* dependencies.sh does its thing, so when 'awk' is not
available, we end up seeing:
support/dependencies/check-host-python3.sh: line 6: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
support/dependencies/check-host-python3.sh: line 19: awk: command not found
which: no awk in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)
You must install 'awk' on your build machine
make: *** [support/dependencies/dependencies.mk:27: dependencies] Error 1

In commit ba70f94e62 (subversion makes it so we do not need a separate
tarball to store empty directories and symlinks for the target_skeleton.)
/etc/resolv.conf was made a symlink to ../tmp/resolv.conf. There was no
rationale behind this change, but back at the time (2006!), the only
location that Buildroot guaranteed to be writable was /tmp, and we
needed a writable location to create resolv.conf from a DHCP reply for
example, so the change made sense.
Commits 2f67d9e2fe (preparation for BR2_PACKAGE_BUSYBOX_SKELETON), in
2007, then d9119c0bc5 (move default skeleton to fs/ and drop busybox
skeleton), in 2010, and finally 6c3e3ad419 (New top-level directory:
system), in 2012, propagated that /etc/resolv.conf without any change in
the target of the symlink.
However, since commit d380dde1d2 (skeleton: make /run a proper
directory/filesystem), in 2015, a tmpfs has been mounted on /run, so it
is now guaranteed to be writable as well for SYS-V-based systems. That
has also been the case for openrc since commit a840e485d1
(package/skeleton-init-openrc: new package), in 2019. This has also
always been the case for systemd as well.
resolv.conf is not a temporary file [0]; it is really more of a runtime
data; its location in /tmp is just a historical artefact of a long-wrong
assertion.
Nowadays, distributions either have an actual file as /etc/resolv.conf
(when /etc is writable), or it is a symlink to a location below /run.
Although resolv.conf is used by the C library resolver, a lot of
applications now will directly use it; this is the case for some
container management tools, such as podman (and its helpers, like
netavark), that expect /etc/resolv.conf to either be a file or a symlink
to somewhere in /run, and fail to provide DNS services if that is not
the case.
So, we move the target of /etc/resolv.conf to ../run/resolv.conf.
As a consequence, we can drop the workaround in podman's runtime test.
To be noted: there are tow custom fstab files in Buildroot that do not
explicitly mount a tmpfs on /run:
- one for a systemd runtime test, so /run would also be a tmpfs there
anyway, as systemd does mount one;
- one for the mender_x86_64_efi_defconfig; that's a not a problem:
/ is an ext4 that is mounted r/w (and /tmp is not a tmpfs either, so
the symlink to /tmp would not not have worked if / was not r/w
anyway).
This leaves people with their own fstab, to adapt. Cater to them by
adding a little blurb in the documentation.
Note: the following 43 tests all built and ran successfully:
tests.init

Currently, only the -static extldflags may be set in the
golang-package infra. However, in some cases, it might be necessary to
pass other flags, either because they are needed on a specific
architecture, or a specific C library; packages may also have a need
to pass arbitrary linker flags when they use CGO linking.
For example, on AArch64, go forcibly uses ld.gold, but it is not
available in all toolchains, and ld.bfd works nowadays (following
patch); another case is musl, where PIE is not supported with go.
Introduce FOO_EXTLDFLAGS, which we use to set those flags, and that
packages can set to pass such flags.

Updating directly to 4.x is too difficult and complex, as mender 4.x is
a complete rewrite in C++, with several new dependencies and changes.
As such, update to the last version that was written in Go, which is
3.5.3. The following changes are necessary:
The artifact_info file is no longer supported. Instead, mender now expects a
bootstrap.mender artifact created by mender-artifact /var/lib/mender.
See the following for more information:

- Remove all instances of creating or copying an artifact_info file
from board examples and package/mender.
- Add a generate_mender_bootstrap_artifact method to
board/mender/x86_64/post-image-efi.sh which creates a proper
bootstrap.mender file and places it in the data partition.
- Add a post-build.sh script to support/testing/tests/package/test_mender
with the same generate_mender_bootstrap_artifact method with one change:
As the rootfs.ext4 file is not yet created; we omit the optional
--provides "rootfs-image.checksum:${img_checksum}" argument when
generating the bootstrap.mender file.
Mender expects the device_type file to exist in /var/lib/mender/device_type.
This is further supported by the following line in tests/Dockerfile.daemon:
`echo device_type=docker-client > /var/lib/mender/device_type`
Add a migration section in docs/manual/migrating.adoc
Update the package/mender/readme.txt to include a quick mention of the

Even when configured for cross-compilation, the go compiler is always
able to build natively as well, and this is was we use in Buildroot to
build host go packages. This implies that when the target has
limitations, those limitations thus also apply to the host builds.
This means that, when there is no CGO linking support for the target,
the compiler is built without CGO linking support, and thus CGO linking
is also not available for the host builds.
Of course, when there is no go support for the target, the CGO linking
support only depends on the host architecture.
Add a new Kconfig symbol that repesent whether CGO linking is available
for the host; host packages can then depend on that symbol, like the
target variants do on the corresponding target symbol.
The dependencies of this symbol are a bit complicated. Fortunately,
because it is a blind symbol, we can write it with a combination of
"default y" and "depends on" statements. As mentioned, CGO for the host
is available if CGO is available for the target, but also if Go is not
available for the target at all. In addition, Go must of course be
available for the host. There are also the toolchain constraints of CGO.
We exclude MIPS64 explicitly based on BR2_HOSTARCH. For the host, we
always assume that dynamic library and threads are available so we don't
have conditions for that.

When the default (newest) kernel headers series changes the build can
break. Example error message:
Incorrect selection of kernel headers: expected 6.8.x, got 6.5.x
In the above case the defconfig used:
BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="6.5.9"
The kernel headers were not specified, so the build defaulted to using
the kernel sources as header source and the default (newest) header
series. From .config:
BR2_KERNEL_HEADERS_AS_KERNEL=y
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_6_8=y

The current implementation of buildroot depe dependency graphing
either does forward- or reverse-dependency traversal.
This patch enables buildroot to graph forward and reverse dependencies
on the graph for the same package: (Diagram Credit: Yann E. MORIN)
$ make pkg-d-graph-both-depends
pkg A -. .-> pkg E
\ /
pkg B ----> pkg D ----> pkg F
/ \
pkg C -' '-> pkg G
In the above example a single graph shows pkg {A,B,C} are needed
by pkg D, and pkg D is a dependency of pkg {E,F,G}.
Makefile help and manual are also updated.

[Arnout:
- remove DEPTH and RDEPTH, their functionality is already covered by
BR2_GRAPH_DEPS_OPTS;
- remove --rdepth, it was felt to not add sufficient added value;
- add the new target to the manual;
- fix flake8 errors.

The manual describes package/busybox/S01syslogd as the reference of
how an init script should be written. Include it from source instead
of having a copy in the manual to ensure actual code and manual stay
in sync.
Also use long options in the paragraph after the script to follow the
same style.

People can assume that e.g. Busybox options enabled in the package are
enabled when writing code for Buildroot. Anyone who uses custom
configurations that disable default options needs to make sure
relevant scripts etc. still work for themselves.
