Bookworm has been deprecated and therefore our internal
repository no longer accepts the publish of new packages.
We are then removing the publish to the internal repositories of bookworm.
Publishing internal image in cloudflared. This allows us to remove the dependency from cloudflare/plat/dockerfiles. In addition, our acceptance tests should now be able to use the latest image instead of relying on a fixed version for testing, which will allow us to detect potential failures earlier.
## What
Bumps go-boring from 1.26.0-1 to 1.26.2-1 and CI builder image from \`3501-fc698419a625\` to \`3595-779e088c0ec4\`.
go1.26.2 (released 2026-04-07) includes security fixes to the \`go\` command, the compiler, and the \`archive/tar\`, \`crypto/tls\`, \`crypto/x509\`, \`html/template\`, and \`os\` packages, as well as bug fixes to the \`net\`, \`net/http\`, and \`net/url\` packages.
### Security fixes (relevant)
- **crypto/tls**: multiple CVEs — cloudflared uses TLS extensively for tunnel connections
- **crypto/x509**: CVE-2026-32280 (excessive chain-building in \`Verify\`), CVE-2026-32281 (quadratic work in policy validation)
### Net bug fixes (not applicable)
- **net/url #78111**: \`url.Parse\` regression for MongoDB-style multi-host URLs — not used in cloudflared
- **net/http #78019**: race condition on Windows when using \`os.File\` as HTTP request body — cloudflared does not pass \`os.File\` as a request body
- **net #77885**: \`ReadMsgUDP\`/\`WriteMsgUDP\` WSAEFAULT on Windows with empty non-nil oob — quic-go uses \`basicConn\` on Windows (\`ReadFrom\`, not \`ReadMsgUDP\`)
## Jira
[TUN-10507](https://jira.cfdata.org/browse/TUN-10507)
Remove the DNS over HTTPS (DoH) proxy feature built on CoreDNS due to
security vulnerabilities (GO-2025-3942, GO-2026-4289).
This removes:
- Standalone proxy-dns command (cloudflared proxy-dns)
- Tunnel subcommand (cloudflared tunnel proxy-dns)
- Proxy-dns flags for tunnel run (--proxy-dns, --proxy-dns-port, etc.)
- Config file resolver section support
- tunneldns/ package (CoreDNS-based implementation)
- Related component tests
BREAKING CHANGE: The proxy-dns feature is no longer available.
Users should migrate to alternative DNS over HTTPS solutions.
* TUN-9863: Introduce Code Signing for Windows Builds
This commit adds a signing step to the build script for windows binaries.
Since we package the MSI on Linux, this commit adds another CI step that depends on package-windows and signs all of the windows packages.
To do so, we use azuresigntool which relies on a certificate stored in Azure Vault.
Closes TUN-9863
## Summary
This commit migrates the cloduflared ci pipelines, that built, tested and component tested the linux binaries to gitlab ci.
The only thing that is remaining to move from teamcity to gitlab are now the release pipelines that run on master.
