This script queries the list of CPE IDs for the packages of the
current configuration (based on the "make show-info" output), and:
- 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
kernel will more then likely not match the upstream version
used in the dictionary

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.:
time ./support/scripts/pkg-stats --nvd-path ~/.nvd -p avahi --html foobar.html
Goes from
174,44s user 2,11s system 99% cpu 2:58,04 total
To
93,53s user 2,00s system 98% cpu 1:36,65 total
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
then pickled into a local file, to speed up the processing of further
invocations.
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,
causing the Python process to be OOM-killed on a server with 4 GB of
RAM.

In commit 7a607dab33
("support/scripts/pkg-stats: support generating stats based on
configured packages"), we added a -c option to pkg-stats to generate a
report based on the list of packages enabled in the configuration,
rather than for all packages.
This is done based on the list of packages returned in JSON format by
"make show-info". However, we use the keys of the JSON dict returned
by "make show-info", which include the host- prefix of host
packages. Due to this, none of the host packages are currently
matching and therefore they are not reported in the pkg-stats -c
output.
This commit fixes that by using the recently introduced "name"
property in the "make show-info" JSON dict.

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
the user later on in the middle of the pkg-stats execution.

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().

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.

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, we handle three kinds of tests: basic, defconfig, and
runtime, and we treat them totally independently ones from the others.
Except for the basic tests that are ignored when defconfig or runtime
tests are explicitly requested.
The basic tests are also run systematically on all our reference
branches: master, next (when it exists), and the maintenance branches:
YYYY.MM.x.
Furthermore, we can see that the conditions to run each set of tests
are very similar, with only the explicit queries differing by name.
Rework the script so that the conditions are expressed only once, and
each set of tests is decided for each condition. This makes it easier
to decide what tests should run under what conditions.
Using GitLab-CI's schedules, with a variable expressing the actual test
to run, would seem the obvious choice to trigger the pipelines. However,
a schedule is configured for a specific branch, which means we would
need one schedule per branch we want to build per test cases we want to
run, *and* that we update those schedules when we add/remove branches
(e.g. when we open/close 'next', or a maintenance branch). This is not
very nice, as it requires some manual tweaking and twiddling on the web
UI.
Instead, we resort to using triggers, that will be triggered from a
cronjob on some server. Using a cronjiob allows us to more easily manage
the branches we want to test and test cases we want to run, to more
easily spread the load over the week, etc...
Note: triggering a pipeline can be done with a simple curl invocation:
$ curl -X POST \
-F "token=${YOUR_TOKEN}" \
-F "ref=${BRANCH_TO_TEST}" \
-F "variables[BR_SCHEDULE_JOBS]=${TEST_TO_RUN}" \

Commit 9e4ffdc8cf modified the output of
'setlocalversion' so that the Buildroot version tag is included in the
output, the version part was added in Makefile.
Due to differences in behavior of the used git and Mercurial commands, this
caused different output for the Mercurial case, in BR2_VERSION_FULL and thus
/etc/os-release and 'make print-version'. Assuming the official Buildroot
releases are tagged and no project-specific tags are present, the output
after commit 9e4ffdc8cf is:
-hg<commit>
whereas it is expected to be something like:
2020.02.6-hg<commit>
Change the Mercurial case in setlocalversion to behave similar to git,
looking up the latest tag if the current revision is not itself tagged.
The number of commits after the latest tag is not added, unlike in git, as
this value is not commonly present in Mercurial output, and its added value
can be disputed in this context. Even one commit could bring a huge change
to the sources, so in order to interpret the number one has to look at the

Add a new option that prints the (runtime) path of compiled .py files
when VERBOSE=1 is set.

When generating a .pyc file, the original .py source file path is
encoded in it. It is used for various purposes: traceback generation,
.pyc file comparison with its .py source, and code inspection.
By default, the source path used when invoking compileall is encoded in
the .pyc file. Since we use paths relative to TARGET_DIR, we end up with
paths that are only valid when relative to '/' encoded in the installed
.pyc files on the target.
This breaks code inspection at runtime since the original source path
will be invalid unless the code is executed from '/'.
Unfortunately, compileall cannot be forced to use the proper path. It
was not written with cross-compilation usage in mind.
Rework the script to call py_compile.compile() directly with pertinent
options:
- The script now has a new --strip-root argument. This argument is
optional but will always be specified when compiling py files in
buildroot.
- All other (non-optional) arguments are folders in which all
"importable" .py files will be compiled to .pyc.
- Using --strip-root=$(TARGET_DIR), the future runtime path of each .py
file is computed and encoded into the compiled .pyc.
No need to change directory before running the script anymore.
The trickery used to handle error reporting was only applicable with
compileall. Since we implement our own "compileall", error reporting
becomes trivial.
Previously, we had a --force option to tell compileall.compiledir() to
forcibly recompile files if they had changed. Now, we would have to
handle it ourselves. It turns out to not be easy and would need us to
delve into the format of bytecompiled files to extract metadata and
compare it with the expected values, that being even dependent on the
python version being used (fortunately, only two for us: python 2.7 and
the latext 3.x).
Still, this is deemed too complex, and byte-compiling is pretty fast, so
much so that it should be eclipsed by the build duration anyway.
So we just drop support for --force, and instead we always byte-compile.
