What this PR does / why we need it

Reduces repeated repository lookups and digest computation when selecting and reconciling component versions that require signatures.

  • Checks all required signature names before loading public keys or starting verification. If a later required signature is missing, earlier signatures no longer incur unnecessary verification work.
  • Returns the verified component handle from version selection and reuses it during reconciliation. This removes the second verification and subsequent source lookup, reducing controller lookups of the selected source version from three to one during an update.
  • Verifies required signatures sharing the same digest specification together, so resource and reference digests are computed once per group. Different digest specifications and duplicate signature names use separate passes, preserving verification of every configured key.
  • Retains signature digest lookups from the precheck and uses direct map access when retrieving public keys from Secrets.
  • Passes the reconciliation context into SDK verification so cancellation can interrupt digest traversal.
  • Closes rejected candidates, selected components, and transferred component handles on success and failure paths.

Version selection continues to scan in descending semver order and chooses the first version satisfying the constraint and all required signatures. Each candidate descriptor still needs to be fetched to inspect its signatures; actual network savings depend on repository caching and resource access methods.

Adds regression coverage for missing and invalid signatures, mixed digest algorithms, duplicate signature names, repository lookup counts, transfers, and handle cleanup.

Validation:

  • go test ./... -count=1
  • golangci-lint run --timeout 10m using v2.14.0 — 0 issues

<h1>Versioning and Release</h1>
<p>This document details the versioning and release plan for containerd.
Stability
is a top goal for this project, and we hope that this document and the
processes
it entails will help to achieve that. It covers the release process,
versioning
numbering, backporting, API stability and support horizons.</p>
<p>If you rely on containerd, it would be good to spend time
understanding the
areas of the API that are and are not supported and how they impact your
project in the future.</p>
<p>This document will be considered a living document. Supported
timelines,
backport targets and API stability guarantees will be updated here as
they
change.</p>
<p>If there is something that you require or this document leaves out,
please
reach out by <a
href="https://github.com/containerd/containerd/issues">filing an
issue</a>.</p>
<h2>Releases</h2>
<p>Releases of containerd will be versioned using dotted triples,
similar to
<a href="http://semver.org/">Semantic Version</a>. For the purposes of
this document, we
will refer to the respective components of this triple as
<code>&lt;major&gt;.&lt;minor&gt;.&lt;patch&gt;</code>. The version
number may have additional information,
such as alpha, beta and release candidate qualifications. Such releases
will be
considered &quot;pre-releases&quot;.</p>
<h3>Major and Minor Releases</h3>
<p>Major and minor releases of containerd will be made from main.
Releases of
containerd will be marked with GPG signed tags and announced at
<a
href="https://github.com/containerd/containerd/releases">https://github.com/containerd/containerd/releases</a>.
The tag will be of the
format <code>v&lt;major&gt;.&lt;minor&gt;.&lt;patch&gt;</code> and
should be made with the command <code>git tag -s
v&lt;major&gt;.&lt;minor&gt;.&lt;patch&gt;</code>.</p>
<p>After a minor release, a branch will be created, with the format
<code>release/&lt;major&gt;.&lt;minor&gt;</code> from the minor tag. All
further patch releases will
be done from that branch. For example, once we release
<code>v1.0.0</code>, a branch
<code>release/1.0</code> will be created from that tag. All future patch
releases will be
done against that branch.</p>
<h3>Release Cadence</h3>
<p>Since containerd v2.3 in April 2026, minor releases are provided on a
time basis
with a cadence of 4 months. New minor releases are scheduled for April,
August,
and December of each year. This cadence is synchronized with the
Kubernetes
release schedule to ensure that new features in containerd can be
smoothly
adopted by new Kubernetes releases.</p>
<p>The maintainers will maintain a roadmap and milestones for each
release, however,</p>

<h2>4.38.3 - 08 Oct 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: CodeQL version 2.21.2 and earlier
were discontinued on 24 September 2026 alongside GitHub Enterprise
Server 3.17, and will be unsupported by the next minor release of the
CodeQL Action. Added a deprecation warning for customers using these
versions of CodeQL. <a
href="https://redirect.github.com/github/codeql-action/pull/4188">#4188</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.2">2.27.2</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4203">#4203</a></li>
<li>Fixed a bug where the decision of whether to use a per-language
bundle did not account for custom configurations that reference queries
outside of compiled CodeQL packs. This issue was caught during internal
testing and did not affect any customer repositories. We will resume the
roll out of per-language bundles in the coming weeks. <a
href="https://redirect.github.com/github/codeql-action/pull/4184">#4184</a></li>
</ul>
<h2>4.38.2 - 24 Sept 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.1">2.27.1</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4160">#4160</a></li>
</ul>
<h2>4.38.1 - 18 Sept 2026</h2>
<ul>
<li>The CodeQL Action now has experimental support for CodeQL releases
for which per-language bundles are available. Per-language bundles
support analysis for a single language and are therefore smaller than
the combined bundles that allow analysis for all supported languages. As
a result, per-language bundles take up less space on disk and are faster
to download. We expect to roll this change out to everyone in the coming
weeks. <a
href="https://redirect.github.com/github/codeql-action/pull/4146">#4146</a></li>
</ul>
<h2>4.38.0 - 09 Sept 2026</h2>
<ul>
<li>On GitHub-hosted runners, the CodeQL Action now deletes unused
CodeQL bundles from the toolcache before downloading a different bundle,
which frees up disk space for the analysis. We expect to roll this
change out to everyone in September. <a
href="https://redirect.github.com/github/codeql-action/pull/4124">#4124</a></li>
<li>The CodeQL Action now supports CodeQL releases that are compatible
with Linux Arm64 and downloads the native <code>linux-arm64</code>
CodeQL bundle when available. <a
href="https://redirect.github.com/github/codeql-action/pull/4072">#4072</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.0">2.27.0</a>.
<a

<ul>
<li>Changed the default filepath for the new remote file address format
that was introduced in CodeQL Action 4.37.0 / 3.37.0 to
<code>.github/codeql-config.yml</code> to align it with the suggested
path that is used elsewhere. <a

<blockquote>
<h2>v4.39.0</h2>
<ul>
<li><em>Breaking change</em>: Bump the minimum required CodeQL bundle
version to 2.20.7. <a
href="https://redirect.github.com/github/codeql-action/pull/4205">#4205</a></li>
<li>The <code>codeql-action/analyze</code> step now validates that a
correct argument for the <code>checkout_path</code> input has been
provided. The <code>checkout_path</code> input must be set to the path
where the repository that is being analyzed is checked out at on the
runner, if that path is something other than the workspace root. If the
path does not point to a repository checkout or is different from the
path that was used by <code>codeql-action/init</code>, then the CodeQL
Action now produces a warning. <a
href="https://redirect.github.com/github/codeql-action/pull/4148">#4148</a></li>
<li>Resolved an issue with third-party caching implementations that
prevented caches from being restored correctly. <a
href="https://redirect.github.com/github/codeql-action/pull/4206">#4206</a></li>
<li>The <code>codeql-action/start-proxy</code> step that is used in Code
Scanning Default Setup now finds CodeQL releases using the same logic as
<code>codeql-action/init</code>. This primarily benefits customers who
are using GitHub instances other than <code>github.com</code> where the
<code>codeql-action/start-proxy</code> step may previously have been
unable to locate recent releases and ended up using outdated versions of
the private registry authentication proxy as a result. <a

</ul>
<h2>4.38.3 - 08 Oct 2026</h2>
<ul>
<li><em>Upcoming breaking change</em>: CodeQL version 2.21.2 and earlier
were discontinued on 24 September 2026 alongside GitHub Enterprise
Server 3.17, and will be unsupported by the next minor release of the
CodeQL Action. Added a deprecation warning for customers using these
versions of CodeQL. <a
href="https://redirect.github.com/github/codeql-action/pull/4188">#4188</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.2">2.27.2</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4203">#4203</a></li>
<li>Fixed a bug where the decision of whether to use a per-language
bundle did not account for custom configurations that reference queries
outside of compiled CodeQL packs. This issue was caught during internal
testing and did not affect any customer repositories. We will resume the
roll out of per-language bundles in the coming weeks. <a
href="https://redirect.github.com/github/codeql-action/pull/4184">#4184</a></li>
</ul>
<h2>4.38.2 - 24 Sept 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.1">2.27.1</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4160">#4160</a></li>
</ul>
<h2>4.38.1 - 18 Sept 2026</h2>
<ul>
<li>The CodeQL Action now has experimental support for CodeQL releases
for which per-language bundles are available. Per-language bundles
support analysis for a single language and are therefore smaller than
the combined bundles that allow analysis for all supported languages. As
a result, per-language bundles take up less space on disk and are faster
to download. We expect to roll this change out to everyone in the coming
weeks. <a
href="https://redirect.github.com/github/codeql-action/pull/4146">#4146</a></li>
</ul>
<h2>4.38.0 - 09 Sept 2026</h2>
<ul>
<li>On GitHub-hosted runners, the CodeQL Action now deletes unused
CodeQL bundles from the toolcache before downloading a different bundle,
which frees up disk space for the analysis. We expect to roll this
change out to everyone in September. <a
href="https://redirect.github.com/github/codeql-action/pull/4124">#4124</a></li>
<li>The CodeQL Action now supports CodeQL releases that are compatible
with Linux Arm64 and downloads the native <code>linux-arm64</code>
CodeQL bundle when available. <a
href="https://redirect.github.com/github/codeql-action/pull/4072">#4072</a></li>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.0">2.27.0</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4129">#4129</a></li>
</ul>
<h2>4.37.9 - 26 Aug 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.4">2.26.4</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4106">#4106</a></li>
</ul>
<h2>4.37.8 - 21 Aug 2026</h2>
<p>No user facing changes.</p>
<h2>4.37.7 - 13 Aug 2026</h2>
<ul>
<li>Update default CodeQL bundle version to <a
href="https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.3">2.26.3</a>.
<a
href="https://redirect.github.com/github/codeql-action/pull/4085">#4085</a></li>
</ul>
<h2>4.37.6 - 04 Aug 2026</h2>
<ul>
<li>Changed the default filepath for the new remote file address format
that was introduced in CodeQL Action 4.37.0 / 3.37.0 to
<code>.github/codeql-config.yml</code> to align it with the suggested
path that is used elsewhere. <a
