Thomas Petazzoni 78d7521f82 support/scripts/pkg-stats: ignore packages with no valid infra and no version for CVE checking
Virtual packages (with in pkg-stats speak have "no valid
infrastructure") and packages that have no version specified cannot be
used for CVE checking. They trigger a bunch of warnings from the CVE
checking code, as it cannot parse their version: they don't have any
version. So instead, we simply skip those packages.

A follow-up commit will improve the reporting to be able to
distinguish those packages from packages that have seen their CVEs
checked and don't have any reported.

Thomas Petazzoni e3ef352ef6 support/scripts/{pkg-stats, cve.py}: support CPE ID based matching
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().

Thomas Petazzoni 8cba5463de support/scripts/gen-bootlin-toolchains: do not assume RPC for glibc toolchains
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.

Thomas Petazzoni 1ff7f003e1 support/scripts/cve.py: properly match CPEs with version '*'
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:2.3suse: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.

Thomas Petazzoni 7a607dab33 support/scripts/pkg-stats: support generating stats based on configured packages
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).

Thomas Petazzoni ae86067a15 support/scripts/pkg-stats: allow to run script outside of the top-level directory
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.

Brandon Maier a0b041d6c1 system: support br2-external init systems
Some externals may wish to provide custom init systems for tightly
integrated boot. This has been supported through the BR2_INIT_NONE,
however a downside to the BR2_INIT_NONE is it forces the custom init
system to use either skeleton-custom and roll a custom skeleton for
each target, or skeleton-init-none which isn't a complete skeleton.

Allowing br2-external to define custom BR2_INIT_* means they can now
safely 'select' the BR2_PACKAGE_SKELETON_INIT_*, and re-use any of the
skeletons in Buildroot, or one from a br2-external tree.

Peter Korsgaard 42f61e759a support/scripts/apply-patches.sh: do not blindly remove *.orig files
apply-patches currently blindly removes *.orig / .*.orig files as GNU patch
by default writes these as backup files when patches only apply with fuzz.

This is unfortunate as package sources may contain files ending in .orig as
well, breaking the build.  Luckily GNU patch can be told to not write these
backup files using the --no-backup-if-mismatch option, so used that instead
of the .orig removal step.

--no-backup-if-mismatch is supported since GNU patch 2.3.8 (1997-06-17) and
busybox patch if built with CONFIG_DESKTOP, but E.G.  isn't supported by the
BSD patch, so add logic to dependencies.sh to error out if patch doesn't
support the flag.

Yann E. MORIN cf8364f202 support/scripts/generate-gitlab-ci-yml: rework generation of pipelines
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]=${TEST_TO_RUN}" \
        "https://gitlab.com/api/v4/projects/${YOUR_PROJECT_ID}/trigger/pipeline"

Thomas De Schampheleire 32eb5a1d16 support/scripts/setlocalversion: fix/improve Mercurial output
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
repository anyhow, in which case the commit ID can just be used.

When multiple conditions match simultaneously, even though that should
not happen in practice, we want the more "important" one to win over
the less "important" ones. For example, a tag is more important than a
branch name or a trigger.

Currently, the latest condition to match takes precendence over any
previous one, while we want the exact opposite.

Fix that with proper fallbacks in else-blocks.

Robin Jarry c566f5206a support/scripts/pycompile: fix .pyc original source file paths
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.

Thomas Petazzoni 184d47a7ad support/scripts/gen-bootlin-toolchains: add new script to support Bootlin toolchains
https://toolchains.bootlin.com/ has been providing for a few years a
number of ready-to-use pre-built toolchains, for a wide range of
architectures (which it turns out, are all built using Buildroot).

While toolchains.bootlin.com provides Buildroot config fragments to
easily use those toolchains with Buildroot (see [0] for example), this
is not visible anywhere. So instead, we would like to add support for
these toolchains in Buildroot just like we have existing support for
Linaro, ARM, Synopsys, etc. toolchains.

[0] https://toolchains.bootlin.com/downloads/releases/toolchains/aarch64/fragments/aarch64--glibc--bleeding-edge-2020.02-2.frag

However, the number of toolchains provided by toolchains.bootlin.com
is really large, and they are regularly updated. Maintaining that
manually would be time consuming and error-prone. So instead, this
commit introduces a script that automatically generates:

 - toolchain/toolchain-external/toolchain-external-bootlin/Config.in.options
 - toolchain/toolchain-external/toolchain-external-bootlin/toolchain-external-bootlin.mk
 - toolchain/toolchain-external/toolchain-external-bootlin/toolchain-external-bootlin.hash
 - support/testing/tests/toolchain/test_external_bootlin.py

We create a single external toolchain package, with a Kconfig "choice"
as a sub-option to select the toolchain variant to be used. The script
contains a Python dict that provides the mapping between the
toolchains provided by toolchains.bootlin.com, and the architecture
options/variants they are applicable to.

The test cases allow to verify that the toolchain configuration is
correct, and that it is able to build a Busybox based system. It
doesn't do any runtime testing as such testing is already done by
toolchains.bootlin.com: the test cases here are only meant to verify
that the toolchain-external-bootlin package works as expected.

The main difference is the removal of the "affects" element that we
were using to check if a package was affected by a CVE.

This information is now available in the "configuration" element which
contains the cpeid as well as properties about the versions
affected. Instead of having a list of the versions affected, with
these properties, it is possible to have a range of versions.

Thomas Petazzoni 008ca2c583 support/scripts/pkg-stats: consider "-" as a wildcard when doing CVE version matching
Some CVE entries in the NVD database have version_value set to "-",
which seems to indicate that it applies to all versions of the
software project, or that they don't really know which versions are
affected, and which are not.

So, for the benefit of doubt, it seems more appropriate to consider
such CVEs as affecting our packages.

This makes the total number of CVEs affecting our next branch jump
from 141 CVEs to 658 CVEs, but that number will go back down once we
switch to the JSON 1.1 schema. Indeed, in the JSON 1.0 schema, there
are often cases where a version_value is set to "=" *and* specific
versions are set to.

This commit slightly improves the output of pkg-stats by showing the
progress of the upstream URL checks and latest version retrieval, on a
package basis:

Checking URL status
[0001/0062] curlpp
[0002/0062] cmocka
[0003/0062] snappy
[0004/0062] nload
[...]
[0060/0062] librtas
[0061/0062] libsilk
[0062/0062] jhead
Getting latest versions ...
[0001/0064] libglob
[0002/0064] perl-http-daemon
[0003/0064] shadowsocks-libev
[...]
[0061/0064] lua-flu
[0062/0064] python-aiohttp-security
[0063/0064] ljlinenoise
[0064/0064] matchbox-lib

Note that the above sample was run on 64 packages. Only 62 packages
appear for the URL status check, because packages that do not have any
URL in their Config.in file, or don't have any Config.in file at all,
are not checked and therefore not accounted.

Thomas Petazzoni 98c99556e3 Makefile: properly account for custom tags in BR2_VERSION_FULL
BR2_VERSION_FULL is currently defined as follows:

  BR2_VERSION_FULL := $(BR2_VERSION)$(shell $(TOPDIR)/support/scripts/setlocalversion)

This BR2_VERSION_FULL value then gets used as the "VERSION" variable
in the /etc/os-release file.

The logic of "setlocalversion" is that if it is exactly on a tag, it
returns nothing.

If it is on a tag + a number of commits, then it returns only
-XYZ-gABC where XYZ is the number of commits since the last tag, and
ABC the git commit hash (these are extracted from git describe).

This output then gets concatenated to BR2_VERSION which gives
something like 2020.05 or 2020.05-00123-g5bc6a.

The issue is that when you're on a tag specific to your project, which
is not a Buildroot YYYY.MM tag, then the output of setlocalversion is
empty, and all you get as VERSION in os-release is $(BR2_VERSION)
which is not really nice. Worse, if you have another non-official
Buildroot tag between the last official Buildroot tag/version and
where you are, you will get $(BR2_VERSION)-XYZ-gABC, but XYZ will not
correspond to the number of commits since BR2_VERSION, but since the
last tag that "git describe" as found, which is clearly incorrect.

Here is an example: you're on master, "make print-version" (which
displays BR2_VERSION_FULL) will show:

$ make print-version
2020.08-git-00758-gc351877a6e

So far so good. Now, you create a tag say 5 commits "before" master,
and show BR2_VERSION_FULL again:

$ git tag -a -m "dummy tag" dummy-tag HEAD~5
$ make print-version
2020.08-git-00005-gc351877a6e

This makes you believe you are 5 commits above 2020.08, which is
absolutely wrong.

So this commit simplifies the logic of setlocalversion to simply
return what "git describe" provides, and not prepend $(BR2_VERSION) in
the main Makefile. Since official Buildroot tags match official
Buildroot version names, you get the same output when you're on an
official Buildroot tag, or some commits above a Buildroot tag. An in
other cases, you get a sensible output. The logic is also adjusted for
the Mercurial case.

In the above situation, with this commit applied, we get:

$ make print-version
dummy-tag-6-g6258cdddeb

(6 commits instead of 5 as we have this very commit applied, but at
least it's 6 commits on top of the dummy-tag)

Finally, if you're not using a version control system, setlocalversion
was already returning nothing, so in this case, the Makefile simply
sets BR2_VERSION_FULL to BR2_VERSION to preserve this behavior.

Romain Naour 2ed3b0a586 gitlab-ci: check all defconfigs on every push
The defconfig check has been introduced by the previous
patch before the building each defconfig but those builds
are done every week or more.

Checking if a defconfig is valid can be done on every
push in the repository since it take few seconds.

This would allow to detect as soon as possible a problem
in a defconfig and eventually avoid breaking the build
while build testing all defconfig.

Introduce a new job template ".defconfig_check" in
gitlab-ci.yml.in and modify the generate-gitlab-ci-yml
to create a job for each defconfig to run the test.

Although, we could have used only one job to do all
tests, using one job per defconfig allow to identify
easily in gitlab which defconfig is falling.
