Add a registry-based allocatable NIC filter extension point for the network resource plugin and emit per-filter NIC state metrics.

Features

What this PR does / why we need it:

Which issue(s) this PR fixes:

Special notes for your reviewer:

English

  • Adds a registry-based extension point for allocatable NIC filters.
  • Adds NICFilters configuration and the network-resource-plugin-nic-filters flag.
  • Applies enabled filters sequentially during NewNICManager initialization.
  • Fails manager initialization when filter creation or execution returns an error.
  • Supports wildcard enablement, deduplication, and unknown-filter validation.
  • Emits per-filter metrics and logs for retained and filtered NICs.
  • Adds unit tests for filter initialization, filtering, metrics, and error handling.
  • The change affects the agent network resource plugin. It does not change controller, scheduler, or release wiring.
  • Filtering is disabled by default when NICFilters is nil. Validate filter configuration before rollout because filters can remove NICs or prevent manager initialization.

简体中文

  • 为可分配 NIC 过滤器增加基于 registry 的扩展点。
  • 增加 NICFilters 配置和 network-resource-plugin-nic-filters 参数。
  • NewNICManager 初始化时按顺序应用已启用的过滤器。
  • 当过滤器创建或执行返回错误时,manager 初始化失败。
  • 支持通配符启用、去重和未知过滤器校验。
  • 增加每个过滤器的指标和日志,用于记录保留及过滤的 NIC。
  • 增加过滤器初始化、过滤、指标和错误处理的单元测试。
  • 该变更影响 agent 的 network resource plugin。不涉及 controller、scheduler 或 release wiring。
  • NICFilters 为 nil 时默认关闭过滤。上线前应验证过滤器配置,因为过滤器可能移除 NIC,或阻止 manager 初始化。

📝 Walkthrough

Walkthrough

The PR adds configurable allocatable NIC filters. The command-line flag propagates filter patterns into NetworkQRMPluginConfig. NewNICManager initializes and applies registered filters before health checks, records filter metrics, and validates filter selection.

该 PR 增加了可配置的可分配 NIC 过滤器。命令行标志会将过滤器模式传递到 NetworkQRMPluginConfigNewNICManager 会在健康检查前初始化并应用已注册的过滤器,记录过滤器指标,并验证过滤器选择。

Changes

Allocatable NIC filtering / 可分配 NIC 过滤

Layer / File(s) Summary
Configuration contract and propagation
cmd/katalyst-agent/app/options/qrm/network_plugin.go, pkg/config/agent/qrm/network_plugin.go
NetworkOptions and NetworkQRMPluginConfig now carry NICFilters. The network-resource-plugin-nic-filters flag defaults to disabled filtering.
NetworkOptionsNetworkQRMPluginConfig 现在携带 NICFiltersnetwork-resource-plugin-nic-filters 标志默认禁用过滤。
Filter interface and registry
pkg/agent/qrm-plugins/network/staticpolicy/nic/filter/*
The package defines AllocatableNICFilter, its factory type, and a registry that rejects duplicate names.
该包定义了 AllocatableNICFilter、工厂类型,以及拒绝重复名称的注册表。
Manager filtering and validation
pkg/agent/qrm-plugins/network/staticpolicy/nic/manager.go, pkg/agent/qrm-plugins/network/staticpolicy/nic/manager_test.go
NewNICManager selects filters, applies them sequentially before health checks, reports namespace-aware kept and filtered NICs, and emits metrics. Tests cover explicit, wildcard, disabled, duplicate, and unknown filter selection, NIC keys, in-place filtering, filter order, and metric samples.
NewNICManager 会选择过滤器,在健康检查前按顺序应用过滤器,报告带命名空间的保留和过滤 NIC,并发出指标。测试覆盖显式、通配符、禁用、重复和未知过滤器选择、NIC 键、原地过滤、过滤器顺序及指标样本。

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to c731c

This change adds configurable NIC filtering and per-filter NIC-state metrics. Filter behavior and error handling are covered, with no current merge-blocking risk identified.

Cover filter initialization and execution errors.

NewNICManager now returns errors from filter factory initialization and Filter. Add deterministic subtests that return sentinel errors from both paths and assert that manager construction returns no manager. This protects the new startup failure contract.

覆盖过滤器初始化和执行错误。

NewNICManager 现在会返回过滤器 factory 初始化和 Filter 的错误。请添加确定性子测试,使两个路径都返回 sentinel error,并断言 manager 构建不返回 manager。这可保护新的启动失败契约。

As per path instructions, prefer deterministic tests that cover failure paths when relevant. 按路径说明,在适用时优先使用覆盖失败路径的确定性测试。

- Line 143: Copy filteredNICs into an independent slice before passing it to
Filter, replacing the shared-storage assignment to before so metric reporting
retains the original NICs and accurately distinguishes kept from filtered
entries. Add a test covering an in-place Filter implementation.
- Line 197: Update the filter selection and execution flow around the registry
iteration so filters run in the configured order rather than Go map iteration
order; resolve each configured name through registry when building the selected
filter list, then execute that list sequentially. Add a deterministic
order-sensitive test using non-commutative filters such as “second” and “first”
to verify the configured order is preserved.
- Line 213: Update the filter resolution logic that returns filters to reject
any explicitly configured filter name that has no registry match, returning a
descriptive startup error instead of an empty filter list. Preserve the existing
documented wildcard matching and disable-selector behavior, and verify config
defaulting does not turn omitted selectors into unknown explicit names.
