charset=UTF-8 Content-Transfer-Encoding: 8bit * RDK-60640: Add PKCS#11 tests for mTLS certificate These tests ensure proper integration between device management service, certificate selector, and PKCS#11 token infrastructure. Background: RDK-60640 implements PKCS#11 support for storing private keys in hardware security modules (HSM) instead of filesystem. This enables production devices to use TPM/OP-TEE for secure key storage while maintaining mTLS connectivity to backend services. Changes: - Add test_pkcs11_fallback.py with 4 test scenarios - Test certificate chain fallback (primary → backup) - Validate mTLS handshake with PKCS#11-backed keys - Integration with SoftHSM2 for CI/test environments - Mock xconf endpoints for certificate validation Test Scenarios: 1. Primary certificate succeeds (happy path) 2. Primary fails, fallback to backup succeeds * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Resolve Copilot review comments and optimize test_pkcs11_fallback.py - Remove duplicate start_daemon/stop_daemon functions - Fix RFC file format: use json.dumps() instead of str() - Merge write_device_prop() and write_rfc_file() into write_config_files() - Improve process management with proper handle passing - Enhance backup_reference_cert fixture with pytest.skip() - Add OpenSSL validation with returncode check - Optimize file size from 363 to 163 lines (55% reduction) - Update run_l2.sh phase labels and descriptions for clarity * Remove test_verify_no_pkcs11_patch_activation from PKCS#11 fallback tests (not needed, key type is EC) * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Use DEVNULL for daemon stdout/stderr and cleanup /opt/curl_progress in fallback test * Fix test_fallback_rdkvfwupgrader_direct timeout: kill lingering daemon before running rdkvfwupgrader * Fix test_fallback_rdkvfwupgrader_direct: increase cleanup delay and kill rdkvfwupgrader to release curl connections * Fix test_fallback_rdkvfwupgrader_direct: use stdout=PIPE without timeout to match other tests * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Address all 3 Copilot review comments: - Capture daemon stdout/stderr for better error diagnostics - Use shutil.copy2/os.replace

Executive Summary + +`librdkFwupdateMgr` is a C shared library (`librdkFwupdateMgr.so`) that provides client applications on RDK-based embedded devices a clean, stable API for firmware lifecycle management. The library acts as a thin, intelligent client-side proxy that communicates with the `rdkFwupdateMgr` daemon over D-Bus (system bus IPC). + +### What Problem Does It Solve? + +Firmware updates on embedded devices require coordination between: +- Cloud infrastructure (XConf configuration server) +- Local device services (download managers, flash subsystems, reboot coordinators) +- Multiple client applications that may each need to initiate or observe firmware updates + +Without this library, every client application would need to: +- Know D-Bus method names, object paths, interface names, and GVariant type signatures +- Manage D-Bus connections, proxies, and signal subscriptions +- Handle threading for asynchronous signal reception +- Implement timeout and retry logic +- Parse raw D-Bus data into usable structures + +This library eliminates all of that complexity. A client app includes one header, links one library, calls five functions, and implements three callback signatures. + +### Key Design Characteristics + +| Characteristic | Decision | Rationale | +|---------------|----------|-----------| +| IPC mechanism | D-Bus (system bus) | Standard Linux IPC, D-Bus policy enforcement, well-understood | +| Threading model | Single background thread + per-call ephemeral connections | Simple, minimal resource usage | +| API style | Async fire-and-forget with callbacks | Non-blocking; suitable for event-driven and threaded apps | +| Memory model | Library owns handle; client owns callback data copies | Clear ownership boundaries | +| Connection model | Stateless (new D-Bus connection per API call) | No connection lifecycle management needed | +| Callback delivery | Background thread invocation | Deterministic delivery; client uses condvar to synchronize | + +--- + +## 2. Why This Library Exists + +### 2.1 The Fundamental Problem + +The `rdkFwupdateMgr` daemon manages all firmware operations on the device: checking for updates, downloading firmware images, flashing them to storage, and coordinating reboots. Multiple client applications need to interact with this daemon: + +- **example_plugin** — A reference one-shot firmware updater +- **TR-069/TR-181 agents** — Remote management protocols that trigger updates +- **WebUI services** — User-facing interfaces showing update status +- **Monitoring daemons** — Health-check services that poll firmware state + +Each of these would need to implement identical D-Bus client logic if they talked to the daemon directly. This is the classic "N-clients × M-operations" maintenance problem. + +### 2.2 What the Library Provides + +``` +WITHOUT library: WITH library: +───────────────── ───────────────── +Client A: 200 lines D-Bus code Client A: 30 lines using 5 API calls +Client B: 200 lines D-Bus code Client B: 30 lines using 5 API calls +Client C: 200 lines D-Bus code Client C: 30 lines using 5 API calls + Library: 1500 lines (maintained once) +``` + +### 2.3 Design Goals + +1. **Simplicity** — Five public functions. Three callback types. One header to include. +2. **Correctness** — Thread-safe, leak-free, handles all error paths. +3. **Stability** — Public API (header) changes require version bumps. Internal implementation can change freely. +4. **Observability** — Structured logging with module separation (`[FWUPMGR]`). +5. **Portability** — Works with or without RDK_LOGGER. Falls back to `fprintf` for unit testing. + +--- + +## 3. Why Clients Must Not Directly Talk to the Daemon + +This section documents the engineering rationale for mandating library usage rather than allowing direct D-Bus calls. + +### 3.1 Protocol Encapsulation + +The D-Bus interface between client and daemon is an **internal protocol**, not a public contract: + +| Aspect | Risk of Direct D-Bus Access | +|--------|---------------------------| +| Method signatures | `(ss) → (t)`, `(ssss)`, `(sssss)` — one typo = crash or silent failure | +| Signal signatures | `(tiissss)`, `(tsuss)`, `(tsiis)` — must parse correctly or lose data | +| Signal subscription setup | Must happen BEFORE method call, or response signal is lost | +| Update details format | Pipe-separated `Key:Value` string — undocumented, may change | +| Handler ID encoding | `uint64` on wire but `char*` in API — format details shouldn't leak | + +If the daemon team changes a signal signature (e.g., adds a field), only the library needs updating — not every client. + +### 3.2 Threading Complexity + +Receiving D-Bus signals requires: +- A dedicated GLib event loop running in a thread +- Signal subscription with correct object path and interface filters +- Proper GMainContext isolation (so the app's own GLib loop isn't disrupted) +- Mutex-protected callback dispatch with deadlock prevention + +No client developer should reimplement this. It's error-prone and already solved in the library. + +### 3.3 Connection Lifecycle + +The daemon identifies clients by `handler_id`, not by D-Bus sender address. This is because our library's stateless model creates a **new D-Bus connection per API call**, meaning each call gets a different sender ID (`:1.140`, `:1.141`, `:1.145`, etc.). + +A naive client attempting direct D-Bus calls would likely assume sender-ID stability — leading to authorization failures at the daemon's process tracking layer. + +### 3.4 Forward Compatibility + +The library provides a stable ABI boundary: +- Daemon protocol changes → library absorbs them internally +- New capabilities (e.g., cancel, pause) → added as new library functions +- Client code recompiles against same header, links same `.so` name + +--- + +## 4. Shared Library Responsibilities + +The library (`librdkFwupdateMgr.so`) is responsible for the following and **only** the following: + +| # | Responsibility | Implementation | +|---|---------------|----------------| +| 1 | **Input validation** | NULL checks, empty string checks, length limits on all public API parameters | +| 2 | **D-Bus transport** | Create connection, build GVariant payloads, send method calls, handle D-Bus errors | +| 3 | **Async signal reception** | Background thread with GLib event loop subscribed to daemon signals | +| 4 | **Callback management** | Three registries (check, download, update) with mutex protection | +| 5 | **Data transformation** | Convert daemon's wire format (GVariant) into typed C structs (`FwInfoData`, progress values) | +| 6 | **Handle lifecycle** | Allocate on register, validate on use, free on unregister | +| 7 | **Structured logging** | All operations logged under `LOG.RDK.FWUPMGR` module | +| 8 | **Resource cleanup** | Thread join, mutex destroy, memory free on deinit — no leaks | + +### What the Library Does NOT Do + +- Does NOT perform actual firmware downloads (daemon does this) +- Does NOT interact with XConf servers (daemon does this) +- Does NOT flash firmware (daemon delegates to HAL) +- Does NOT manage reboots (daemon handles this) +- Does NOT persist state across process restarts +- Does NOT retry failed operations (client's responsibility) +- Does NOT own the logging lifecycle (`log_init`/`log_exit` are caller's job) + +--- + +## 5. Daemon Responsibilities + +For context, here is what the `rdkFwupdateMgr` daemon does (the other side of the D-Bus): + +| # | Responsibility | Details | +|---|---------------|---------| +| 1 | **Process registration** | Assign unique handler_id, track client metadata, enforce one-registration-per-process-name | +| 2 | **XConf query** | HTTP request to XConf server with device model, current firmware version, MAC address | +| 3 | **Firmware download** | HTTP/HTTPS download from CDN, chunked transfer, integrity verification | +| 4 | **Flash coordination** | Write firmware to appropriate storage partition via device HAL | +| 5 | **Progress reporting** | Emit D-Bus signals with percentage and status as operations progress | +| 6 | **Multi-client orchestration** | Coalesce duplicate download requests (piggybacking), serialize flash operations | +| 7 | **Reboot management** | Coordinate post-flash reboot timing based on client's `rebootImmediately` flag | +| 8 | **Cleanup on client disconnect** | Handle ungraceful client exits (D-Bus name owner watching) | + +--- + +## 6.

Security Considerations + +### 13.1 D-Bus Policy Enforcement + +Access control is enforced at the D-Bus level via policy files: +```xml + + + + + +``` + +Only processes running as the configured user (typically root or a specific service account) can call methods or receive signals. + +### 13.2 Handler ID as Authorization Token + +The `handler_id` (e.g., `"12345"`) serves as the session authorization token: +- It's a daemon-generated 64-bit value (not guessable from outside) +- Required for all operations after registration +- The daemon validates that the handler_id exists before processing any request +- In this library model, sender-ID validation is not used (see Section 9.2 for why) + +**Limitation**: The handler_id is a sequential counter (not cryptographically random). In a multi-client environment, a malicious client could potentially guess another client's handler_id. For production hardening, consider using a random 128-bit token. + +### 13.3 Input Validation at Library Boundary + +All public API functions validate inputs before forwarding to D-Bus: +- NULL pointer checks on all parameters +- Empty string rejection +- Length limit enforcement (prevents buffer overflow in daemon's fixed-size buffers) +- Numeric parse validation in `unregisterProcess()` (strict `strtoull` with endptr check) + +### 13.4 No Credential Storage + +The library does not store, cache, or transmit any credentials. Authentication is entirely handled by D-Bus policy and daemon-side process tracking. + +### 13.5 Memory Safety + +- No `sprintf()` usage — all string formatting uses `snprintf()` with bounds +- All `strncpy()` usage explicitly null-terminates the destination +- Handle memory is freed exactly once (in `unregisterProcess()`) +- Registry entries are freed on slot reset — no dangling pointers +- GLib objects are unreffed on all code paths (including error paths) + +--- + +## 14. Performance Considerations + +### 14.1 Overhead Per API Call + +| Operation | Typical Latency | Bottleneck | +|-----------|----------------|------------| +| `registerProcess()` | 5-10ms | D-Bus round-trip | +| `checkForUpdate()` | <1ms (returns immediately) | D-Bus message queueing | +| `downloadFirmware()` | <1ms (returns immediately) | D-Bus message queueing | +| `updateFirmware()` | <1ms (returns immediately) | D-Bus message queueing | +| `unregisterProcess()` | 10-15ms | pthread_join + D-Bus round-trip | + +### 14.2 Memory Footprint + +| Component | Size | Notes | +|-----------|------|-------| +| Three registries (static arrays) | ~30 × 3 × (272 bytes per entry) ≈ 24 KB | Stack-like, no heap fragmentation | +| Background thread stack | 8 MB default (configurable) | Linux thread default | +| GMainLoop + GMainContext | ~2 KB | GLib internal | +| D-Bus connection (persistent) | ~4 KB | Background thread's connection | +| Per-call D-Bus proxy | ~2 KB | Freed immediately after call | + +**Total resident overhead**: ~35 KB (excluding thread stack, which is virtual memory only) + +### 14.3 Connection Overhead + +The per-call connection model has overhead: +- Each `g_bus_get_sync()` call performs a D-Bus handshake +- Each gets a unique sender name allocated by dbus-daemon +- Connection teardown releases the name + +For infrequent firmware operations (minutes/hours between calls), this overhead is negligible. If call frequency were high (>10/second), a persistent connection pool would be warranted. + +### 14.4 Signal Dispatch Efficiency + +The two-phase dispatch creates a stack-local snapshot array on every signal. With `MAX_PENDING_CALLBACKS=30` and ~272 bytes per snapshot entry, this is ~8KB of stack usage — well within typical 8MB thread stack limits. + +The linear scan of 30 entries is O(30) — negligible for this use case. A hash map would be over-engineering. + +--- + +## 15. Scalability for Multiple Clients + +### 15.1 Current Capacity + +| Resource | Limit | Constraint | +|----------|-------|------------| +| Concurrent registered processes | Limited by daemon's `registered_processes` hash table | Effectively unbounded (GHashTable) | +| Concurrent pending checkForUpdate callbacks | 30 | `MAX_PENDING_CALLBACKS` constant | +| Concurrent active downloads | 30 | Same constant for download registry | +| Concurrent active updates | 30 | Same constant for update registry | + +### 15.2 Multi-Client Signal Delivery + +D-Bus signals are **broadcast** — all connected clients receive them. The library's dispatch logic handles this: + +``` +Daemon emits CheckForUpdateComplete: + ├─ Client A's background thread receives it → dispatches to Client A's callback + ├─ Client B's background thread receives it → dispatches to Client B's callback + └─ Client C's background thread receives it → dispatches to Client C's callback +``` + +Each client has its own library instance (separate `.so` loaded into its process space), its own background thread, its own registries. They are completely independent. + +### 15.3 Daemon-Side Coalescing + +For download operations, the daemon implements **piggybacking**: if multiple clients request the same firmware file simultaneously, the daemon downloads it once and sends progress signals to all registered clients. The library dispatches these signals to all ACTIVE download callbacks transparently. + +### 15.4 Scaling Limitations + +- If more than 30 checkForUpdate calls are pending simultaneously (across the same process), the 31st will fail with `CHECK_FOR_UPDATE_FAIL`. This is unlikely in practice — 30 concurrent firmware checks from one process would be a design error. +- The background thread is single-threaded — if a callback takes a long time (e.g., client does heavy processing in the callback), other signals queue up in the GMainContext. Clients should keep callbacks short and signal their main thread for heavy work. + +--- + +## 16. Future Extensibility + +### 16.1 Potential New APIs + +| API | Purpose | Priority | +|-----|---------|----------| +| `cancelDownload(handle)` | Abort an in-progress download | High | +| `pauseDownload(handle)` / `resumeDownload(handle)` | Pause/resume for network bandwidth management | Medium | +| `getUpdateStatus(handle)` | Synchronous poll of current state (for apps that don't want callbacks) | Medium | +| `setUpdatePolicy(handle, policy)` | Configure auto-update behavior per client | Low | +| `subscribeToDeviceState(handle, cb)` | Get notified of device firmware state changes (not just self-initiated) | Low | + +### 16.2 HAL Integration (Planned) + +The `UpdateCallback` signature documentation notes: +> "The signature and behavior of this callback may change in future versions when HAL (Hardware Abstraction Layer) APIs become available." + +When HAL is integrated: +- More granular progress reporting (per-partition) +- Device-specific status codes +- Verification step callbacks (checksum validation) + +### 16.3 Persistent Connection Model (If Needed) + +If call frequency increases or the daemon implements per-connection state: +- Replace per-call `g_bus_get_sync()` with a connection pool +- Add reconnection logic on connection drop +- Add heartbeat/keepalive mechanism + +### 16.4 User-Data in Callbacks + +Current callback signatures don't include a `void *user_data` parameter (e.g., `UpdateEventCallback` takes only `const FwInfoData*`). Adding user_data would: +- Eliminate the need for global variables in client apps +- Allow multiple independent sessions in one process +- Be an ABI-breaking change (major version bump) + +### 16.5 Async/Await Style (C11 Atomics) + +For modern C codebases, consider offering a "future" API alongside callbacks: +```c +// Hypothetical future API: +FwCheckFuture *future = checkForUpdateAsync(handle); +// ... do other work ... +FwInfoData *result = awaitFwCheck(future, timeout_ms); // blocks until ready +freeFwCheckFuture(future); +``` + +This would be a convenience wrapper over the existing callback mechanism. + +--- + +## Appendix A: Complete D-Bus Interface Contract + +``` +Service: org.rdkfwupdater.Service +Path: /org/rdkfwupdater/Service +Interface: org.rdkfwupdater.Interface + +METHODS: + RegisterProcess(s processName, s libVersion) → (t handler_id) + UnregisterProcess(t handler_id) → (b success) + CheckForUpdate(s handle) + DownloadFirmware(s handle, s firmwareName, s downloadUrl, s typeOfFirmware) + UpdateFirmware(s handle, s firmwareName, s location, s type, s rebootImmediately) + +SIGNALS: + CheckForUpdateComplete(t handler_id, i result_code, i status_code, + s current_version, s available_version, + s update_details, s status_message) + + DownloadProgress(t handler_id, s firmware_name, u progress_percent, + s status_string, s message) + + UpdateProgress(t handler_id, s firmware_name, i progress_percent, + i status_code, s message) +``` + +--- + +## Appendix B: End-to-End Sequence Diagram + +``` + Client App (main) librdkFwupdateMgr BG Thread Daemon + ───────────────── ───────────────── ───────── ────── + │ │ │ │ + │ registerProcess() │ │ │ + │──────────────────────────►│ │ │ + │ │── D-Bus: Register ───────────────────────►│ + │ │◄──── handler_id ─────────────────────────┤ + │ │── internal_system_init() │ + │ │ └─ pthread_create() ──►│ │ + │ │ │─ subscribe ──►│ + │ │ │ signals │ + │ │◄── running=true ─────────┤ │ + │◄── handle "12345" ────────┤ │ │ + │ │ │ │ + │ checkForUpdate(h, cb) │ │ │ + │──────────────────────────►│ │ │ + │ │── register cb in reg. │ │ + │ │── D-Bus: CheckForUpdate ─────────────────►│ + │◄── SUCCESS ───────────────┤ │ │ + │ │ │ │ + │ [waiting on condvar] │ │ XConf... │ + │ │ │ │ + │ │ │◄── signal ────┤ + │ │ │ │ + │ │ on_check_complete_signal() │ + │ │ dispatch_all_pending() │ + │ │ │ │ + │◄──────────────────────────│────── cb(&fwinfo) ◄┘ │ + │ [condvar signaled] │ │ + │ │ │ + │ downloadFirmware(h,r,cb) │ │ + │──────────────────────────►│ │ + │ │── register dl_cb │ + │ │── D-Bus: DownloadFirmware ───────────────►│ + │◄── SUCCESS ───────────────┤ │ │ + │ │ │◄── 25% ───────┤ + │◄──── dl_cb(25,INPROG) ────│──────────────────────────┤ │ + │ │ │◄── 100% ──────┤ + │◄──── dl_cb(100,DONE) ─────│──────────────────────────┤ │ + │ │ │ + │ unregisterProcess(h) │ │ + │──────────────────────────►│ │ + │ │── internal_system_deinit() │ + │ │ └─ quit loop ──────────►│ exits │ + │ │ └─ join ◄──────────────┘ │ + │ │── D-Bus: Unregister ─────────────────────►│ + │ │── free(handle) │ + │◄── return ────────────────┤ │ + │ │ │ +``` + +--- + +## Appendix C: Build and Integration + +### Library Build (Autotools) + +```makefile +# librdkFwupdateMgr/Makefile.am +lib_LTLIBRARIES = librdkFwupdateMgr.la + +librdkFwupdateMgr_la_SOURCES = \ + src/rdkFwupdateMgr_process.c \ + src/rdkFwupdateMgr_api.c \ + src/rdkFwupdateMgr_async.c + +librdkFwupdateMgr_la_CFLAGS = \ + -I$(top_srcdir)/librdkFwupdateMgr/include \ + -I$(top_srcdir)/librdkFwupdateMgr/src \ + -I$(top_srcdir)/common_utilities/utils \ + $(GIO_CFLAGS) $(GLIB_CFLAGS) + +librdkFwupdateMgr_la_LIBADD = \ + $(GIO_LIBS) $(GLIB_LIBS) -lpthread + +# Installed public header +librdkFwupdateMgr_includedir = $(includedir)/rdkFwupdateMgr +librdkFwupdateMgr_include_HEADERS = include/rdkFwupdateMgr_client.h +``` + +### Client Linking + +```makefile +my_app_LDADD = -lrdkFwupdateMgr -lfwutils -lrdkloggers $(GIO_LIBS) +my_app_CFLAGS = -I$(includedir)/rdkFwupdateMgr +``` + +### Minimum Client Code + +```c +#include "rdkFwupdateMgr_client.h" +#include "rdkv_cdl_log_wrapper.h" + +int main(void) { + log_init();
