d/s merge, fix security in d/s - #343
Conversation
Handle transient certificate errors during daemon startup to prevent crash-loops when pods restart during the certificate rotation window (~3 seconds) where the symlink is temporarily removed or the file is empty. Changes: - Add isTransientCertError() to classify errors as transient vs permanent using string matching (the cert store wraps errors with %v, destroying type information, so errors.As is ineffective here) - Use errors.As for NoCertKeyError (returned directly, not wrapped) and retry it in the poll callback since it is expected during initial provisioning and during rotation when the symlink is briefly removed - Transient errors (file not found, empty/invalid PEM) return (false, nil) in the existing 1-second poll, retrying naturally - Permanent errors fail fast via (false, err) instead of polling for the full 2-minute timeout - Add unit tests for isTransientCertError covering all error cases Assisted by Claude Opus 4.6 Signed-off-by: Benjamin Pickard <bpickard@redhat.com>
Both pkg/multus and pkg/server tests used /tmp/foo.multus.conf as the readiness indicator file. Since go test ./... runs packages in parallel, pkg/multus AfterEach would delete the file while pkg/server STATUS/GC tests were polling for it, causing intermittent failures. Rename to /tmp/foo.multus.server-test.conf to avoid the collision.
This is a follow-up to k8snetworkplumbingwg/multus-cni#1512 for issues found while carrying the Kubernetes and Go bump into downstream. The dependency verifier reported vendor drift for vendor/k8s.io/api/scheduling/v1alpha2/generated.proto after go mod tidy and go mod vendor. Re-running those commands on this upstream branch produced no vendor diff, so no vendor file change is included. The security scan reported path traversal findings in kubeconfig_generator and multus-daemon because CLI-controlled paths were passed directly to file operations. This change validates those paths, requires absolute paths, rejects empty, relative, and parent-directory paths, and uses os.Root with local file names for file reads, writes, creates, and removes.

…rabbityaml-for-multus-cni Create .coderabbit.yaml for multus-cni
The poll loop in PerNodeK8sClient special-cased NoCertKeyError with its own errors.As check before calling isTransientCertError, while the helper separately classified the same error as non-transient. CodeRabbit and a human reviewer flagged this duplication on the original PR as producing confusing, contradictory semantics. isTransientCertError now owns the full classification, including NoCertKeyError, and the poll loop's redundant check is removed. Also move the err.Error() call below the errors.As check to avoid an unused allocation on that path, and flip the NoCertKeyError test case to match.

Error from logs: Snyk reports the vendored go/InsecureHash finding under vendor/golang.org/x/tools/internal/pkgbits. What happened: After the Kubernetes and Go bump, the downstream security scan still flags golang.org/x/tools internal pkgbits code from vendor. This is vendored analyzer/compiler-support code, not Multus runtime path-handling code. What changed: Add vendor/golang.org/x/tools/internal/pkgbits to the existing .snyk global exclusions. Keep the downstream carry limited to scan policy only and do not duplicate the shared upstream command-path fixes. After the fix: The downstream security scan should stop reporting the vendored pkgbits go/InsecureHash finding. The final downstream merge PR still needs to be refreshed after upstream PR #1524 lands so the os.Root path-handling fix and SIGKILL cleanup arrive through the upstream merge.

In @.github/workflows/performance-report.yml:
- Around line 96-102: Update the BASELINE_INFO assignment to capture the
get-baseline-run.py output while assigning "{}" to BASELINE_INFO on failure,
preventing the fallback from being emitted as stray stdout and ensuring
subsequent ID and URL parsing receives valid JSON.
In `@cmd/multus-daemon/main.go`:
- Around line 256-260: Update copyUserProvidedConfig in
cmd/multus-daemon/main.go at lines 256-260 and its configPath, srcPath, srcFile,
and dstPath handling so deferred Close errors are returned only when no earlier
error exists. Apply the same error-aware deferred-close handling to all rooted
handles in cmd/kubeconfig_generator/main.go at lines 76-88, preserving any
existing earlier error.
- Line 230: Update all Go build images to Go 1.26 to match the go.mod
requirement and avoid automatic toolchain downloads;
cmd/multus-daemon/main.go:230, pkg/cmdutils/utils.go:28-29, and
cmd/kubeconfig_generator/main_test.go:90-92 are affected usage sites and require
no direct code changes.
In `@Dockerfile.microshift`:
- Around line 6-7: Set GOFLAGS to -mod=readonly in Dockerfile.microshift and
Dockerfile.openshift at lines 6-7, replacing -mod=mod so the go build commands
run by hack/build-go.sh cannot modify go.mod or go.sum; keep GO111MODULE=on
unchanged.
In `@e2e/kubeburner/templates/webserver-deployment.yml`:
- Around line 19-20: Remove the hard-coded node-role.kubernetes.io/worker
nodeSelector from the webserver deployment, or make it configurable and unset by
default. Ensure scheduling remains compatible with single-node and other
supported topologies without requiring a worker-role label.
In `@e2e/perf/get-pr-info.py`:
- Around line 31-55: Update find_prs_by_head_branch so the gh pr list --head
argument always uses head_branch rather than the owner-qualified head_ref;
retain the existing headRepositoryOwner filtering for head_owner.
In `@images/Dockerfile.openshift`:
- Line 3: Update the Dockerfile’s builder and runtime FROM directives to replace
the mutable local/okdbuilder:latest and quay.io/openshift/origin-base:latest
references with reviewed `@sha256` digest-pinned references, while preserving the
existing build stages.
- Line 5: Update the Dockerfile around its ADD instructions to use COPY for
local files, explicitly copying only the source paths required by the build
rather than the entire context. Add or update .dockerignore to exclude
credentials and generated artifacts, and preserve the required build inputs at
both the current ADD locations.
- Around line 11-23: Update the Dockerfile around the runtime configuration and
ENTRYPOINT to declare an explicit non-root USER instead of inheriting the base
image’s user, and ensure that user has the required permissions for the host CNI
paths used by the copied Multus binaries before the image starts.
In `@pkg/server/api/api_test.go`:
- Around line 46-52: Update the startup error check around serveErrCh so a
received serve error remains available for cleanup, or ensure cleanup skips the
second channel read when startup already consumed it; preserve the existing
handling of non-shutdown errors and avoid blocking when server.Serve returns
before the helper exits.
- Line 16: Update the listener setup around SocketPath to use
net.ListenConfig.Listen with a bounded context instead of net.Listen. Preserve
server startup errors by handling the result from server.Serve so the startup
select reports it immediately and does not leave t.Cleanup blocked reading an
empty serveErrCh.

Go 1.25 go command go.mod go 1.26.0 automatic toolchain switching GOTOOLCHAIN auto documentation
💡 Result:
In Go, automatic toolchain switching is a mechanism that allows the 'go' command to automatically detect and use a newer version of the Go toolchain than the one currently running, if a project's configuration requires it [1][2]. This behavior is primarily controlled by the 'GOTOOLCHAIN' environment variable and the directives in 'go.mod' or 'go.work' files [1][3]. GOTOOLCHAIN Configuration The 'GOTOOLCHAIN' environment variable determines how the 'go' command handles toolchain selection [1]. It can be set globally (e.g., via 'go env -w GOTOOLCHAIN=...') or per-command [1][3]. Common settings include: - auto (default): Allows the 'go' command to automatically download and switch to a newer toolchain if the 'go.mod' or 'go.work' file requires a version newer than the current one [1][2]. - local: Disables automatic downloads; the 'go' command will only use the installed (local) toolchain [2]. If the local toolchain is older than the required version, the command will fail [1][2]. - [version]+auto: Begins with a specific default toolchain version but still permits automatic upgrades to newer versions if required [1][4]. 'go.mod' Directives The 'go.mod' file supports two directives that influence this selection [3][5]: - go [version]: Specifies the minimum Go language version required for the module [5][6]. - toolchain [version]: Explicitly suggests a specific Go toolchain version to use [5][6]. This takes effect when the project is the main module and the current toolchain is older than the suggested one [5]. - toolchain default: A special value that disables automatic toolchain switching for the module, forcing the use of the default toolchain [5][7]. Starting in Go 1.25, the distribution includes fewer prebuilt tool binaries, and tools not invoked directly by build or test operations are managed via 'go tool' as needed [8]. In later versions like Go 1.26, internal package improvements—such as 'NewSwitcher' in 'cmd/go/internal/toolchain'—further refined the logic for switching to newer toolchains to resolve version requirements [9][10]. To check the current configuration or modify it, you can use: go env GOTOOLCHAIN go env -w GOTOOLCHAIN=auto Users should generally prefer 'go get go@version' or 'go get toolchain@version' to update these directives, rather than manual editing [11].

Use Go 1.26 for the build images. The go.mod file declares Go 1.26.0, but the images use Go 1.25 and may rely on automatic toolchain downloads. Builds with GOTOOLCHAIN=local or without download access can fail.

quay.io/openshift/origin-base:latest Dockerfile USER effective user
💡 Result:
The quay.io/openshift/origin-base image (historically known as openshift/origin-base) does not explicitly set a USER instruction in its base Dockerfile [1]. Consequently, when run as a standalone container outside of an orchestrated environment, it defaults to the root user (UID 0) [2]. However, when this image is used as a base for OpenShift-compliant applications, it is designed to support OpenShift's security model, which enforces non-root execution [3][4]. In OpenShift, containers are typically assigned an arbitrary UID by the platform's Security Context Constraints (SCC) at runtime [5][2]. This effectively overrides any USER directive present in the Dockerfile [5]. For best practices when building images intended for OpenShift (including those derived from origin-base), developers are advised to [2][4]: 1. Design the image to support running as an arbitrary user [2]. 2. Ensure that directories and files required by the application are owned by the root group (GID 0) [2]. 3. Grant group-write permissions (chmod g+rw) to those directories so they remain writable regardless of the random UID assigned by OpenShift [6][2][4].

Snyk Code CLI .snyk exclude global excluded files are not tested documentation
💡 Result:
To exclude files or directories from Snyk Code CLI scans, you can use the.snyk policy file with an exclude section [1][2]. The global group within this file applies exclusions to Snyk Code as well as other supported Snyk products [1][3]. Configuration Syntax To exclude files or directories using the.snyk file, add an exclude block at the root of the file using YAML syntax [1][2]: # Snyk (https://snyk.io) policy file exclude: global: - path/to/exclude - "*.pattern.ext" - directory_name/ When you use the global group, the specified files and directories are excluded from Snyk Code tests, Snyk Secrets, and other Snyk products that support this configuration [1][3]. If you only want to exclude files from Snyk Code specifically, you can use the code group instead of global [1][2][3]. Alternative Method: Using the CLI You can also exclude files or folders from Snyk Code tests by using the snyk ignore --file-path command [4][5]. This command automatically creates or updates the.snyk file in your repository with the specified path [4]. For example: snyk ignore --file-path='path/to/exclude' --file-path-group='global' Note the following details: - Exclusions via the.snyk file apply to the Snyk Web UI, CLI, and IDE environments [1]. - The.snyk file must be located in the root of your repository, and the patterns should be relative to that root [2][3]. - While the.snyk file is commonly used to ignore vulnerabilities in other Snyk products, its use with Snyk Code is strictly for excluding files and directories from being scanned (import) [6][1][2]. It cannot be used to ignore specific Snyk Code vulnerability findings [6][1]. - The CLI --exclude option (used with other Snyk test types) does not apply to Snyk Code scans [7].

Keep executable CI helpers in security analysis.
The global .snyk exclusion omits four Python helpers from Snyk Code analysis, but .github/workflows/performance-report.yml executes all four. The “not shipped in downstream images” rationale does not cover this CI execution path. Keep these helpers in the scan, or use a scanner-supported exclusion for confirmed false positives.

Yes.
That change was made by us in upstream commit:
8ac7d5c53 Remove uncatchable SIGKILL from kubeconfig generator
It removed syscall.SIGKILL from signal.Notify because SIGKILL cannot be caught by the process, so cleanup code can never run for kill -9.
It was a follow-up to the static analysis/CodeRabbit finding on the upstream branch, then it landed in upstream #1524 and came into downstream through the merge. It was not manually added downstream.
