Merge Risk: 🟡 Moderate · up to The feature is disabled by default, but enabling it can block host-network router access or stall workspace reconciliation. Policy failures can also delay stopping and leave failure status unreported. Resolve these issues before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Policy failures can prevent workspace shutdown, and matching policies can be replaced or removed without validating their existing ownership. Per-workspace targeting and default-disabled provisioning limit normal exposure, but recovery and ownership safeguards need attention. Retained concerns

- Around line 171-177: Update the SyncNetworkPolicy error handling so FailError
status is persisted through updateWorkspaceStatus before returning, and so a
NetworkPolicy sync failure does not prevent the stopped-workspace flow from
reaching stopWorkspace; log the failure and continue when workspace.Spec.Started
is false.
In `@pkg/config/defaults.go`:
- Around line 180-186: Update GetDefaultConfig to apply the platform-specific
defaults, including NetworkPolicy, PodSecurityContext, ContainerSecurityContext,
and Overrides, when infrastructure is initialized; return the resulting deep
copy so embedding callers can extend it.
- Around line 160-171: Update defaultOpenShiftIngressPolicyRules to add an
ingress peer selected by the policy-group.network.openshift.io/host-network
label with an empty PodSelector, while preserving the existing monitoring and
ingress rules.
In `@pkg/provision/sync/diffopts.go`:
- Around line 95-97: Update networkPolicyDiffOpts to include
cmpopts.EquateEmpty() so nil and empty slices compare equally during
NetworkPolicy diffs; preserve the existing ignored fields.

Persist NetworkPolicy failures and continue stopping stopped workspaces.
SyncNetworkPolicy runs before the deferred status update. A FailError can therefore update only the in-memory status and return before the failure reaches the workspace. The API server can reject invalid NetworkPolicy fields, and SyncObjectWithCluster maps those errors to FailError.
The same return occurs before the stopped-workspace branch. A NetworkPolicy failure can prevent stopWorkspace from running.
Suggested fix
err = networkpolicy.SyncNetworkPolicy(workspace, clusterAPI)
- if shouldReturn, reconcileResult, reconcileErr := r.checkDWError(workspace, err, "Error provisioning network policy", metrics.ReasonInfrastructureFailure, reqLogger, &reconcileStatus); shouldReturn {
- return reconcileResult, reconcileErr
+ if !workspace.Spec.Started {
+ if err != nil {
+ reqLogger.Error(err, "Error syncing network policy while stopping workspace")
+ }
+ } else if shouldReturn, reconcileResult, reconcileErr := r.checkDWError(workspace, err, "Error provisioning network policy", metrics.ReasonInfrastructureFailure, reqLogger, &reconcileStatus); shouldReturn {
+ if _, ok := err.(*dwerrors.FailError); ok {
+ return r.updateWorkspaceStatus(workspace, reqLogger, &reconcileStatus, reconcileResult, reconcileErr)

What does this PR do?
Adds optional per-DevWorkspace
NetworkPolicyprovisioning, configurable throughDevWorkspaceOperatorConfig.New API —
config.workspace.networkPolicy(NetworkPolicyConfig):enabledingress[]→ deny all ingress; non-empty → exactly those rules (defaults are replaced, not appended to).egress[]→ deny all egress; non-empty → exactly those rules.Note: NetworkPolicy configurations are updated on a per-workspace basis whenever the workspace is reconciled (e.g., when it is started or stopped).
What issues does this PR fix or reference?
https://redhat.atlassian.net/browse/WTO-598
Is it tested? How?
Enable the feature in the global DWOC:
Create and start a DevWorkspace, then check that the policy exists and targets only that workspace:
Confirm the workspace started successfully and operates normally with network access.
Stop the DevWorkspace:
Tighten the rules in the DWOC to block all ingress and egress:
Start the DevWorkspace again:
Verify that no network connections can be established to or from the workspa
