GitHub Actions reusable workflows workflow_call inputs untrusted input shell injection env variable security documentation
💡 Result:
In GitHub Actions, using untrusted input—including inputs passed to reusable workflows via workflow_call—directly within run script steps presents a significant risk of shell injection [1][2][3]. Because the ${{ }} syntax is expanded by the GitHub Actions runner before the shell script executes, any malicious content contained within an input can break out of its intended context and execute arbitrary commands on the runner [1][2][4]. To secure your workflows against this, follow these recommended practices: 1. Use Intermediate Environment Variables (Primary Mitigation): Never use ${{ inputs.input-name }} directly inside a run script [1][5]. Instead, map the input to an environment variable in the env section of the job or step [1][6]. This ensures the value is passed to the shell as data rather than being interpreted as part of the script itself [5][3]. Example: yaml jobs: example-job: runs-on: ubuntu-latest steps: - name: Secure use of input env: USER_INPUT: ${{ inputs.my-input }} run: | # Use the environment variable, not the input directly echo "Processing: $USER_INPUT" 2. Validate Inputs: Treat all data coming from a caller workflow as untrusted, especially if that data originates from external sources like pull request titles, body text, or branch names [1][7][2]. Implement strict validation within the reusable workflow, such as using type: choice with a defined list of allowed options or manually validating the input against a regex or allowlist within your script [7]. 3. Prefer Actions over Inline Scripts: When possible, use a JavaScript-based custom action to process complex inputs [5][8]. Because actions accept inputs as arguments rather than generating shell scripts, they are inherently less vulnerable to the types of injection that plague run commands [5]. 4. Leverage Security Tools: Use tools such as CodeQL, actionlint, or community-developed linting rules (like reusable-workflow-taint) to automatically detect dangerous usage of inputs [9][1][10][3]. These tools can identify when inputs are passed directly into script contexts and alert you to potential vulnerabilities before they are exploited [9][1][4]. Reusable workflows inherit the security context of the caller, including access to secrets and tokens [7]. Always follow the principle of least privilege by explicitly passing only the necessary secrets and avoiding secrets: inherit unless strictly required [7][6].

GitHub public reusable workflow called by workflows in other repositories runner context self-hosted runners security
💡 Result:
When using self-hosted runners with reusable workflows across repositories, security risks arise primarily from the persistence of these runners and the potential for unauthorized code execution [1][2]. Because self-hosted runners are not ephemeral, a compromised runner can retain access to environments, secrets, and credentials long after a malicious job finishes [1][2]. To secure this setup, prioritize the following practices: Runner Group Access Control: You can restrict access to self-hosted runner groups at the organization or enterprise level [1][2]. To improve security, configure runner groups to only accept jobs from specific, trusted workflow files [3][4]. By combining this with reusable workflows, you can enforce that highly privileged deployments—such as those requiring production secrets—only execute on dedicated, hardened runner groups, preventing other, less secure workflows from accessing those resources [3][4]. Reusable Workflow Hardening: - Pin by SHA: Always reference reusable workflows using a full-length commit SHA rather than tags or branches to prevent supply chain attacks where a malicious actor updates a tag to point to compromised code [5][6][7]. - Principle of Least Privilege: Explicitly define permissions for all jobs within the reusable workflow [5]. Avoid broad GITHUB_TOKEN permissions (e.g., set to contents: read by default) and only escalate them where absolutely necessary [5]. - Use OIDC: Wherever possible, replace long-lived secrets with OpenID Connect (OIDC) to authenticate with cloud providers [3][8][5]. This eliminates the risk of stolen static credentials if a runner is compromised [5]. Runner Hygiene: - Isolation: Avoid using self-hosted runners for public repositories, as pull requests from untrusted contributors can easily compromise the runner environment [1][2]. - Segmentation: Use separate runner groups to create security boundaries between different types of workloads (e.g., separating production deployment runners from general build/test runners) [1][2]. - Egress Filtering: Consider using tools like Harden-Runner to restrict and audit the network traffic allowed from your runners, providing a layer of defense even if a workflow is compromised [5][9]. When a reusable workflow is called, it executes in the context of the caller repository [10][7]. Therefore, the caller retains responsibility for the security posture of the execution, including the secrets passed to the workflow and the runner environment it ultimately consumes [10][5].

Do not expand inputs.type into shell source.
GitHub expands this value before Bash runs. A value such as x$(printf INJECTED >&2) executes the command substitution. Pass the value through env, then use case to allow only smoke and full.

Resolve relative kubeconfig paths before changing directories.
The script captures KUBE_CONF before cd "${REPO_ROOT}", but later file checks and kubectl commands resolve relative paths from the repository root. A caller that passes a relative path from another directory can receive a false “file not found” error or use a different kubeconfig. Convert the path to an absolute path before cd.

Kubernetes kubectl --request-timeout flag supported versions current reference deprecated removed
💡 Result:
The --request-timeout flag for kubectl is currently supported and has not been deprecated or removed [1][2][3]. As of August 20, 2026, official Kubernetes documentation confirms that --request-timeout remains a standard global flag for kubectl [1][2]. It is used to specify the length of time to wait before giving up on a single server request [1][3]. The value should be provided as a duration (e.g., 1s, 2m, 3h), with a default value of 0, which signifies that there is no timeout [1][2]. Recent developments in the Kubernetes codebase continue to maintain and fix issues related to this flag, further confirming its active status [4].

🌐 Web query:
site:github.com/kubernetes/kubernetes kubectl --request-timeout cobra flag history
💡 Result:
The --request-timeout flag for kubectl was introduced in Kubernetes 1.4 (via PR #33958 in 2016) as a global option to prevent kubectl commands from hanging indefinitely [1]. Key historical points regarding this flag: 1. Functionality: The flag allows users to specify the duration of a request before it times out [1]. A value of 0s (the default) indicates no timeout, meaning the command will wait indefinitely [1]. 2. Implementation: It is implemented as a global configuration flag [1]. Historically, this global nature caused technical issues when used in combination with in-cluster authentication (e.g., inside a Pod) [2][3]. For years, providing the --request-timeout flag would incorrectly override the entire configuration object, causing kubectl to fail when trying to use in-cluster credentials [4][5]. 3. Known Issues and Fixes: - In-cluster configuration conflict: Various issues were reported over the years regarding the flag breaking in-cluster config [2][3]. A significant fix was introduced in later versions to ensure the flag correctly updates only the timeout value without corrupting the rest of the configuration [5]. - Discovery timeout bugs: Further refinements were required to address bugs where the timeout was not being respected correctly for certain REST APIs or discovery client calls [6]. The flag continues to be a standard tool for controlling request duration in automation and scripting environments to avoid indefinite hangs [1].

Bound all preflight Kubernetes requests.
The default --request-timeout=0 allows these three requests to wait indefinitely. Add one non-zero --request-timeout value to each kubectl call. --request-timeout is a supported global kubectl option.

a100 fits seven 1g.5gb, the second pod schedules and this fails. fill capacity first. was this run on a mig node?

In `@hack/e2e-mig-smoke-test.sh`:
- Around line 133-140: Before creating the smoke-fill pods in the overflow
workflow, validate that the configured TARGET_NODE supports seven 1g.5gb MIG
instances; if the geometry is unavailable, fail immediately with a clear
unsupported-GPU message. Use the existing TARGET_NODE and profile_count-related
helpers rather than proceeding to create smoke-overflow, while preserving the
current overflow assertions for supported hardware.
- Around line 134-135: Update the readiness loop around wait_ready to capture
each background PID, wait on every PID individually, and record whether any
wait_ready invocation fails; only return failure after all readiness checks have
completed, while preserving parallel execution.

What type of PR is this?
/kind feature
What this PR does / why we need it:
Connect MIG E2E to formal targets:
hack/hami-mig-e2e.shis now reachable viamake e2e-mig-test, with a wrapper script (hack/e2e-mig-test.sh) that validates kubeconfig, target node, and GPU capacity before running the full MIG matrix.Lightweight MIG smoke test for PR gates: Added
make e2e-mig-smoke-testbacked byhack/e2e-mig-smoke-test.sh, which runs a minimal MIG allocation + overflow rejection scenario. Full MIG matrix is reserved for nightly/release.GPU preflight fail-fast:
hack/e2e-test-setup.shnow exits with error instead of warning when nonvidia.com/gpu.present=truenode is found.GetGPUNode()intest/utils/node.goreturns an error instead of falling back to a non-GPU node.GitHub Actions integration: Added
call-e2e-mig.yamlreusable workflow with separatedeploy-typeinput (maps topullrequest/releasefordeploy-helm.sh). MIG smoke test runs on every PR; full MIG test runs on release.Minor test utility fixes: Removed hardcoded
time.SleepfromCreatePodandKubectlExecInPod.Which issue(s) this PR fixes:
Fixes #
Special notes for your reviewer:
miglabel andMIG_TARGET_NODEset in repository variables.wait_counthelper (copied fromhami-mig-e2e.sh) to avoid coupling.Does this PR introduce a user-facing change?:
No. This only adds E2E test infrastructure and CI workflow changes.
