From f354a5ec7818bf44189885923147e07c85153d52 Mon Sep 17 00:00:00 2001 From: Rongsong Shen Date: Fri, 17 Apr 2026 09:32:21 +0000 Subject: [PATCH] feat: P0-2c register routes + RBAC for host control/select Routes and RBAC entries already existed from prior P0-2a/2b work. This adds three TDD tests that lock down the RBAC invariants: - TestRBAC_HostControl_ClusterAdminOnly: cluster_admin has host:control with domain=all; basic_user must NOT have host:control - TestRBAC_HostView_BasicUserHasAccess: basic_user has host:view with domain=all; queue_admin must NOT have host:view - TestRBAC_HostControl_DomainTypeIsAll: cluster_admin host:control domain type must be "all" (not hostgroup) All apiserver tests passing. --- src/docs/apiserver-backend-tasks.md | 18 ++- .../apiserver/controllers/rbac_check_test.go | 141 ++++++++++++++++++ 2 files changed, 153 insertions(+), 6 deletions(-) diff --git a/src/docs/apiserver-backend-tasks.md b/src/docs/apiserver-backend-tasks.md index 4d1a524d..12a04b3e 100644 --- a/src/docs/apiserver-backend-tasks.md +++ b/src/docs/apiserver-backend-tasks.md @@ -60,15 +60,21 @@ - `lib/testsuite/test_request.c` — 8 TDD validation tests (null ep/ctrl/hostname, empty hostname, HOST_DO_NONE no-op, HOST_TAG/UNTAG reject, negative action) - Regenerated capnp via `ninja -C build` -- [ ] **#7 P0-2b: Implement Go-side ControlHost + fix allFlag race** (unblocked) - - `backend/clib.go` — Replace `ControlHost()` stub with real implementation via `xcecli_hostctrl()` - - `controllers/hosts.go` — Fix data race: remove `var allFlag bool`, return from `preCheckHostControlRequest` as local - - `controllers/queues.go` — Same allFlag data race fix (lines 534-536 / 465) +- [x] **#7 P0-2b: Implement Go-side ControlHost + fix allFlag race** + - `backend/clib.go` — Replaced `ControlHost()` stub with real `xcecli_hostctrl()` call;
