The heuristic to extract the various variables of interest is pretty
crude: we filter on variables ending with certain suffixes (like
'%_VERSION' to get the version strings).
However, in doing so, we may dump variables that are not actual package
versions (especially with br2-external trees), and those may contain one
or more equal sign. And anyway, an actual package version string may
very well contain an equal sign too.
But the current situation is that the output of 'printvars' is split on
all equal signs, which will not fit in the 2-tuple we assign the result,
thus causing an exception.
Fix that by limiting to a single split.

Currently when a tag is added to the Buildroot git tree, the gitlab-ci
create a pipeline with several hundred of jobs (~750) to build all
defconfigs and execute the Buildroot testsuite.
However, there is only a limited number of gitlab-ci runner (9 runners)
and some jobs reach the timeout limit (24h) while waiting for a runner
[1]. Indeed, the Buildroot project doesn't use the Gitlab's shared
runners.
In addition to the pipeline created when a new tag is added to the
git repository, two pipelines are created each weeks to execute the
Buildroot testsuite (on monday [2]) and build all defconfigs (on
Thursday [3]).
At some point there are too many jobs waiting in gitlab due board
defconfigs builds. Indded a board defconfig requires a lot of time
(~30min) compared to other jobs in order to build a toolchain and a
kernel linux along with a basic rootfs. There is currently 262
defconfigs.
This is even worse when several pipelines are trigged at the same
time (new git tag and scheduled pipeline trigger).
In order to reduce the number of long jobs, don't build board
defconfigs with pipelines trigged on tag, keeping only the runtime
tests and the Qemu's defconfigs.

The current Gitlab CI mechanism allows to trigger all tests in a CI
pipeline by pushing a branch named <something>-runtime-tests, or to
trigger a single test in a CI pipeline by pushing a branch name
<something>-tests.<name of test>.
However, there are cases where it is useful to run a suite of tests,
for example to run all tests in tests.init.test_busybox.
This commit makes that possible by extending the current semantic of
<something>-tests.<name of test> to not expect a complete test name,
but instead to accept all tests that starts with the given pattern.
This allows to do:
git push gitlab HEAD:foobar-tests.init.test_busybox.TestInitSystemBusyboxRo
like it was the case before. But it now also allows to do:
git push gitlab HEAD:foobar-tests.init.test_busybox
to run all Busybox tests.

The pkg-stats script queries release-monitoring.org to find the latest
upstream versions of our packages. However, up until recently,
release-monitoring.org had no notion of stable
vs. development/release-candidate versions, so for some packages the
"latest" version was in fact a development/release-candidate version
that we didn't want to package in Buildroot.
However, in recent time, release-monitoring.org has gained support for
differentiating stable vs. development releases of upstream
projects. See for example
https://release-monitoring.org/project/10024/ for the glib library,
which has a number of versions marked "Pre-release".
The JSON blurb returned by release-monitoring.org has 3 relevant
fields:
- "version", which we are using currently, which is a string
containing the reference of the latest version, including
pre-release.
- "versions", which is an array of strings listing all versions,
pre-release or not.
- "stable_versions", which is an array of string listing only
non-pre-release versions. It is ordered newest first to oldest
last.
So, this commit changes from using 'version' to using
'stable_versions[0]'.
As an example, before this change, pkg-stats reports that nfs-utils
needs to be bumped to 2.5.5rc3, while after this patch, it reports
that nfs-utils is already at 2.5.4, and that this is the latest stable
version (modulo an issue where Buildroot has 2.5.4 and
release-monitoring.org has 2-5-4, this will be addressed separately).
Note that part of this change was already done in commit f7b0e0860, but
it was incomplete.

The pkg-stats scripts tries to match packages against
release-monitoring.org in two ways:
- First by using the "Buildroot" distribution registered on
release-monitoring.org, in which we have added a lot of mappings
between Buildroot package names and release-monitoring.org package
names. If there is a match using this distribution, the package
status is RM_API_STATUS_FOUND_BY_DISTRO, which means that the
resulting HTML has a "found by distro" statement.
- Then, if the first solution didn't work, by using the pattern
matching, as done in the check_package_get_latest_version_by_guess()
function.
However, there is a bug in this later case: it sets the package status
to RM_API_STATUS_FOUND_BY_DISTRO as well, while it should have been
RM_API_STATUS_FOUND_BY_PATTERN. Due to this bug, in the resulting HTML
file from a pkg-stats run, all packages are marked as "found by
distro" even the ones that are "found by guess".
This commit fixes that by setting the correct package status.

The gitlab-ci support in test-pkg allows to parallelize the test-pkg
work into several gitlab jobs. It's much faster than local serialized
testing.
To trigger this, a developer will have to add, in the latest commit of
their branch, a token on its own line, followed by a configuration
fragment, e.g.:
test-pkg config:
SOME_OPTION=y
# OTHER_OPTION is not set
SOME_VARIABLE="some value"
This configuration fragment is used as input to test-pkg.
To be able to generate one job per test to run, we need the list of
tests in the parent pipeline, and the individual .config files (one per
test) in the child pipeline. We use the newly-introduced --prepare-only
mode to test-pkg, and collect all the generated .config files as
artefacts; those are inherited in the child pipeline via the
"needs::pipeline" and "needs::job" directives. This is a bit tricky,
and is best described by the Gitlab-CI documentation [0].
We also list those .config files to generate the actual list of jobs to
run in the child pipeline.
Notes:
- if the user provides an empty fragment, this is considered an error:
indeed, without a fragment (and the package name), there is no way
to know what to test;
- if that fragment yields an empty list of tests, then there is
nothing to test either, so that is also considered an error.

This script queries the list of CPE IDs for the packages of the

- for CPE IDs that do not have any matching entry in the CPE
database, it emits a warning
- for CPE IDs that do have a matching entry, but not with the same
version, it generates a snippet of XML that can be used to propose
an updated version to NIST.
Ref: NIST has a group email (cpe_dictionary@nist.gov) used to
recieve these version update and new entry xml files. They do
process the XML and provide feedback. In some cases they will
propose back something different where the vendor or version is
slightly different.
Limitations
- Currently any use of non-number version identifiers isn't
supported by NIST as they use ranges to determine impact
of a CVE
- Any Linux version from a non-upstream is also not supported
without manually adjusting the information as the custom

ijson < 2.5 (as available in Debian 10) use the slow python backend by
default instead of the most efficient one available like modern ijson
versions, significantly slowing down cve checking. E.G.:

To

E.G. almost 2x as fast.
As a workaround, detect when the python backend is used and try to use a
more efficient one instead. Use the yajl2_cffi backend as recommended by
upstream, as it is most likely to work, and print a warning (and continue)
if we fail to load it.
The detection is slightly complicated by the fact that ijson.backends used
to be a reference to a backend module, but is nowadays a string (without the
ijson.backends prefix).

As reported on IRC by sephthir, the gitlab test of the defconfig
qemu_sparc_ss10_defconfig doesn't error out while the system
is not working properly.
This is because we explicitly wait for the timeout as an expected
condition, but do not check for it. Indeed, pexpect.expect() returns
the index of the matching condition in the list of expected conditions,
but we just ignore the return code, so we are not able to differentiate
between a successful login (or prompt) from a timeout.
By default, pexepect.expect() raises the pexpect.TIMEOUT exception on a
timeout, and we are already prepared to catch and handle that exception.
But because pexpect.TIMEOUT is passed as an expected condition, the
exception is not raised.
Remove pexpect.TIMEOUT from the list of expected conditions, so that the
exception is properly raised again, and so that we can catch it.
The qemu_sparc_ss10_defconfig is already fixed by

Currently, the CPE XML database is parsed into a Python dict, which is

However, it turns out that since the initial implementation, we have
switched the XML parsing from the out of tree xmltodict module to the
standard ElementTree one, which has made the parsing much faster. The
pickle caching only saves 6 seconds, on something that takes more than
13 minutes total.
In addition, this pickle caching consumes a significant amount of RAM,

This is done based on the list of packages returned in JSON format by

by "make show-info", which include the host- prefix of host
packages. Due to this, none of the host packages are currently

The cve module needs ijson, which may not be installed. Since cve
matching is only enabled when --nvd-path is passed, it is a bit silly
to error out about ijson being missing if it's not used.
So instead of unconditionally importing the cve module, only do it
conditionally.
However, instead of doing it right at the point where it is used, we
do it at the beginning of the main() function. Indeed, if the cve
module is needed but cannot be imported, we want to error out
immediately rather than doing a whole bunch of things, and failing on

This commit modifies cve.py, as well as its users cve-checker and
pkg-stats to support CPE ID based matching, for packages that have CPE
ID information.
One of the non-trivial thing is that we can't simply iterate over all
CVEs, and then iterate over all our packages to see which packages
have CPE ID information that match the CPEs affected by the
CVE. Indeed, this is an O(n^2) operation.
So instead, we do a pre-filtering of packages potentially affected. In
check_package_cves(), we build a cpe_product_pkgs dict that associates
a CPE product name to the packages that have this CPE product
name. The CPE product name is either derived from the CPE information
provided by the package if available, and otherwise we use the package
name, which is what was used prior to this patch.
And then, when we look at CVEs, we only consider the packages that
have a CPE product name matching the CPE products affected by the
CVEs. This is done in check_package_cve_affects().

This commit improves the pkg-stats script to show the CPE ID of
packages, if available. For now, it doesn't use CPE IDs to match CVEs.

The logic in gen-bootlin-toolchains was assuming all glibc toolchains
have RPC support, which is no longer true since glibc 2.32 has dropped
RPC support.
It turns out that gen-bootlin-toolchains already had some proper logic
that selects BR2_TOOLCHAIN_HAS_NATIVE_RPC depending on the presence of
BR2_TOOLCHAIN_EXTERNAL_INET_RPC in the toolchain fragment. As such
toolchain fragments have been fixed in https://toolchains.bootlin.com,
we can now rely on this to properly decide if the toolchain has RPC
support or not.

When boot-qemu-image.py script was added, we wanted to run
each qemu defconfig in gitlab, so we expect that all qemu
defconfig generate the script start-qemu.sh in images
directory.
Don't make it a hard requirement even if we prefer to be
able to do a runtime test for each qemu defconfig.

Currently, when the version encoded in a CPE is '-', we assume all
versions are affected, but when it's '*' with no further range
information, we assume no version is affected.
This doesn't make sense, so instead, we handle '*' and '-' in the same
way. If there's no version information available in the CVE CPE ID, we
assume all versions are affected.
This increases quite a bit the number of CVEs and package affected:
- "total-cves": 302,
- "pkg-cves": 100,
+ "total-cves": 597,
+ "pkg-cves": 135,
For example, CVE-2007-4476 has a CPE ID of:
cpe:2.3🅰️gnu:tar:*:*:*:*:*:*:*:*
So it should be taken into account. In this specific case, it is
combined with an AND with CPE ID
cpe:2.3⭕suse:suse_linux:10:*:enterprise_server:*:*:*:*:* but since
we don't support this kind of matching, we'd better be on the safe
side, and report this CVE as affecting tar, do an analysis of the CVE
impact, and document it in TAR_IGNORE_CVES.

Now that pkg-stats is able to generate its output based on the list of
packages enabled in the current configuration, cve-checker doesn't
serve any purpose.

pkg-stats was initially a Buildroot maintenance oriented tool: it was
designed to examine all Buildroot packages and provide
statistics/details about them.
However, it turns out that a number of details provided by pkg-stats,
especially CVEs, are relevant also for Buildroot users, who would like
to check regularly if their specific Buildroot configuration is
affected by CVEs or not, and possibly check if all packages have
license information, license files, etc.
The cve-checker script was recently introduced to provide an output
relatively similar to pkg-stats, but focused on CVEs only.
But in fact, its main difference is on the set of packages that we
consider: pkg-stats considers all packages, while cve-checker uses
"make show-info" to only consider packages enabled in the current
configuration.
So, this commit introduces a -c option to pkg-stats, to tell pkg-stats
to generate its output based on the list of configured packages. -c is
mutually exclusive with the -p option (explicit list of packages) and
-n option (a number of packages, picked randomly).

Currently, pkg-stats expects being executed from Buildroot's top-level
source directory. As we are going to extend pkg-stats to cover only
the packages available in the current configuration, it makes sense to
be able to run it from the output directory, which can be anywhere
compared to Buildroot's top-level directory.
This commit adjusts pkg-stats to this, by inferring all Buildroot
paths based on the location of the pkg-stats script itself.

Extract from bug report:
"Code line 120 to line 128 is to check whether the patch containing
"rename from" and "rename to". But it directly use grep to find,
ignoring the patch may be a tar file or else. It can only work on patch
of textfile form."
