* [client,proxy,management,signal,relay] Distrust compromised eMudhra CA keys
Eight eMudhra intermediate CA private keys were compromised and browsers
blocked them on 2026-10-17. Our binaries were built with go1.26.7, which
accepts chains through those intermediates whenever the trust store still
holds emSign ECC Root CA - G3. go1.26.10 rejects them in crypto/x509 on
every platform, regardless of the trust store.
The UBI base still ships the root and Red Hat has no fixed package yet, so
the UBI images blocklist it with p11-kit. The ingest image, the UI server
image and the pinned Chainguard digests also carried the root and move to
bases that no longer do.
* [client,proxy,management,signal,relay] Use the fixed UBI base instead of a blocklist
Red Hat shipped ca-certificates 2026.2.92_v9.0.319-90.3 on 2026-10-22,
which drops emSign ECC Root CA - G3 and AAA Certificate Services. The
current ubi9-minimal image carries it, so pin that digest and remove the
p11-kit blocklist step.
* [misc] Pin upload-server images by digest only and restore go.mod comment
* [management] Add a release-wired UBI image variant
OpenShift and other Red Hat environments expect UBI-based images that run
as an arbitrary non-root UID. The proxy, combined server and rootless
client already ship -ubi variants; this adds the same for management,
published as <version>-ubi and ubi-latest for amd64 and arm64.
The default --port of 80 cannot bind without root, so the image defaults
to 8080. For Let's Encrypt, public 443 forwards to --port and
--letsencrypt-listen-address is empty (#7706), so the main listener
answers the TLS-ALPN challenges.
* [management] Certify the management UBI image
Adds management to the Red Hat certification components. Its Partner
Connect component ID goes in the REDHAT_CERT_ID_MANAGEMENT repository
variable.
