Some software decides based on uid/gid whether a user is a system or
normal (human) user, with different behaviour for those flavors (example
journald [2]).
So adding logic to create system-users is necessary, we take the now
common ranges from [1].
This extends the mkusers script to allow -2 for uid/gid, this argument
will take an identifier from the user range. All identifiers used up to
now should have been from the system range, so -1 is now interpreted as
a system user/group.
Note that after this commit, all the UIDs and GIDs that are created
automatically (with -1) will change. That means if there is peristent
data on an existing system that was created by such an automatic user,
it will suddenly belong to a different user. However, this could already
happen before: if a USERS line is added to a package, then other UIDs
may change as well.
Add system/user ranges as variables, and the argument for user/system
uid variable as well. Thus some magic constants could be removed, some
further occurences of -1 were replaced with equivalent logic. For
consistency, the existing MIN/MAX_UID/GID variables are renamed to
FIRST/LAST_USER_UID/GID.
Update the documentation with the new automatic ranges.

Commit 1ba85b7f87 (support/download: add explicit no-hash support)
introduced the 'none' hash type, in an attempt to make hash files
mandatory, but not failing on archives localy generated, like those
for git or svn repositories, especially for those packages where a
version choice was present, which would allow for either remote
archives for which we'd have a hash or VCS trees for which we could
not have a hash for the localy generated archive.
Indeed, back in the time, we did not have a mean to generate
reproducible archives, so having a hash file without a hash for
thosel ocally generated archives would trigger an error in the
hash-checking machinery.
But now, low-and-behold, we do know how to generate those archives,
and we have a mechanism to explicitly exclude some archives from being
hash-checked (e.g. when the version string itself can be user-provided).
As such, the 'none' hash type no longer has any raison d'être, we do not
use it in-tree, and its use in a br2-external tree is most probably
inexistent (as is the use of hash files alotgether most probably).
So we simply drop the support for that.

The .affects() method of the CVE class in support/scripts/cve.py can
return 3 values: CVE_AFFECTS, CVE_DOESNT_AFFECT and CVE_UNKNOWN.
We of course properly account for CVEs where .affects() return
CVE_AFFECTS, but the ones for which CVE_UNKNOWN is returned are
currently ignored, and therefore treated as if they did not affect the
package.
However CVE_UNKNOWN in fact indicates that the v_start/v_end fields of
the CPE entry could not be parsed by
distutils.version.LooseVersion(). Instead of ignoring such cases, this
commit adds support for the concept of "unsure CVEs", which will be
listed next to CVEs known to affect the package, so that we are aware
of them and can investigate the version issue.

In a follow-up commit, we are about to bump python-cryptography to a
new version, which has the interesting charateristic of using Rust
code. This means python-cryptography will now only be available on
platforms supported by Rust, which for now excludes uclibc-based
configurations (none of the Rust Tier1/Tier2 platforms use uClibc,
there is some uClibc support in Tier3 platforms but they have not been
added to Buildroot for now).
So in preparation for this bump, we switch the few test cases of
Python packages that directly or indirectly use python-cryptography to
use a glibc toolchain. Another impacted test case is the

In most pure Rust packages, the Cargo.toml manifest is at the root
directory, which is why we could call "cargo vendor" without
specifying the path of the manifest.
However, other packages, such as python-cryptography, which have parts
implemented in Rust, have their Cargo.toml located in a specific
subdirectory.
This commit extends the cargo-post-process download script to
understand a BR_CARGO_MANIFEST_PATH environment variable, which allows
a package to pass the location of the Cargo.toml file. If not passed,
"Cargo.toml" is used, preserving the existing behavior for other

For now, the download post-process logic uses mk_tar_gz, which repacks
a tarball compressed with gzip. So we can only accept as input a
tarball also compressed with gzip. To enforce that, this commit
changes post_process_unpack() to use tar xzf. This makes sure that if
a tarball compressed with something else than gzip gets used, it will
bail out and we will notice.

The original patch for commit cff428fe31 ("download/git: support Git
LFS") included a call to "git lfs install" but this was a problem as it
could modify ~/.gitconfig outside the dl/ tree. When this was
updated it was thought that the modification to gitconfig was
unnecessary because the LFS fetch and checkout steps are performed
manually.
Unfortunately, this is not correct and the LFS checkout fails with:
Cannot checkout LFS objects, Git LFS is not installed.
Add the call to "git lfs install", with the --local option so that only
the repository's .git/config is modified and not the user's global
~/.gitconfig.
This is also required for submodules as the parent repository's config
is not inherited.

Currently, relocate-sdk.sh must be run _after_ relocating the SDK. There
are cases where it is useful to already prepare the SDK _before_
relocating. For example, it allows to prepare a tarball that the user
has to extract to a specific, pre-defined location and nothing more than
that, which is simpler for the user than requiring the script to be run.
In addition, it hides the build directory that was used by the SDK
builder (somewhat).

Add download test infrastructure which starts an OpenSSH server using
the sshd binary installed on the Buildroot host. This server can then be
used to test the expected usage of the SCP and SFTP download methods.
The test creates new SSH keys for the server and client, so that the

A new test module has been added called `tests.download.sshd` which
contains helper methods to create the SSH keys and a class called
`OpenSSHDaemon` which handles the sshd server component.
