Pull request overview

Reverts the earlier move to the Thunder PowerController client by switching TR-69 HostIF power interactions back to the IARM Power Manager (PWRMgr) API and removing the related Thunder stub/linking.

Changes:

Replace PowerStatus retrieval and power-mode change notifications from Thunder PowerController to IARM PWRMgr.
Remove PowerController unit-test stubs and drop the -lWPEFrameworkPowerController linkage/build steps.
Simplify/cleanup DeviceInfo and IARM handler code paths affected by the revert.

src/hostif/profiles/DeviceInfo/Device_DeviceInfo.h	Removes PowerController-enable interface hook.
src/hostif/profiles/DeviceInfo/Device_DeviceInfo.cpp	Uses IARM PWRMgr GetPowerState for `X_COMCAST_COM_PowerStatus`.
src/hostif/handlers/src/hostIf_IARM_ReqHandler.cpp	Registers PWRMgr mode-change event handler instead of PowerController callback/thread.
src/Makefile.am	Removes `-lWPEFrameworkPowerController` from link flags.
cov_build.sh	Removes building/linking the PowerController stub library during coverage build.

cov_build.sh:77

cov_build.sh still builds mock-parodus (via mock_parodus_build.sh), but src/hostif/parodusClient/pal/mock-parodus/Makefile.am currently references the deleted src/unittest/stubs/powerctrl_stubs.cpp. This will break CI/coverage builds; remove that source from the mock-parodus build (or provide an alternative stub) to match the deletion in this PR.


cd ./src/hostif/parodusClient/pal/mock-parodus/

IARM_Bus_RegisterEventHandler(...) return value is ignored. If registration fails, deep-sleep notifications will silently stop working while TR69_HostIf_Mgr_Get_RegisterCall() still reports success. Check the return code, log on failure, and incorporate it into ret.

Suggested change

IARM_Bus_RegisterEvent(IARM_BUS_TR69HOSTIFMGR_EVENT_MAX);

IARM_Bus_RegisterEventHandler(IARM_BUS_PWRMGR_NAME,IARM_BUS_PWRMGR_EVENT_MODECHANGED, _hostIf_EventHandler);

IARM_Result_t iarmRet;

iarmRet = IARM_Bus_RegisterEvent(IARM_BUS_TR69HOSTIFMGR_EVENT_MAX);

The PWRMgr event handler registered in TR69_HostIf_Mgr_Get_RegisterCall() is never unregistered on shutdown. Before terminating IARM, remove/unregister the handler (e.g., IARM_Bus_RemoveEventHandler(...)/IARM_Bus_UnRegisterEventHandler(...)) to avoid callbacks into torn-down code and keep lifecycle symmetric.

+            strncpy((char *)stMsgData->paramValue, pwrState, str_len);
+            stMsgData->paramValue[str_len+1] = '\0';
+            stMsgData->paramLen = str_len;


strncpy is copying str_len bytes but the code null-terminates at paramValue[str_len+1], which leaves paramValue[str_len] undefined and can write past the intended end. Null-terminate at str_len (or use a bounded API like snprintf/strncpy_s) and ensure the write stays within TR69HOSTIFMGR_MAX_PARAM_LEN.

+    else
    {
-        RDK_LOG(RDK_LOG_ERROR,LOG_TR69HOSTIF,"Powercontroller Interface failed : %d. Try after sometime. \n", bPowerControllerEnable);
+        RDK_LOG(RDK_LOG_ERROR,LOG_TR69HOSTIF,"Failed in IARM_Bus_Call() for parameter : %s [param.type:%s with error code:%d]\n",stMsgData->paramName, pwrState, ret);


The failure log prints ret (still NOK) as the error code, and the format label param.type:%s is misleading (it prints pwrState). Log the actual IARM_Result_t err (and/or method/owner) so failures are diagnosable.

Suggested change

RDK_LOG(RDK_LOG_ERROR,LOG_TR69HOSTIF,"Failed in IARM_Bus_Call() for parameter : %s [param.type:%s with error code:%d]\n",stMsgData->paramName, pwrState, ret);

RDK_LOG(RDK_LOG_ERROR,LOG_TR69HOSTIF,"Failed in IARM_Bus_Call() for parameter: %s [IARM_Result:%d]\n", stMsgData->paramName, err);

+    err = IARM_Bus_Call(IARM_BUS_PWRMGR_NAME,
+                        IARM_BUS_PWRMGR_API_GetPowerState,
+                        (void *)&param,
+                        sizeof(param));
+    if(err == IARM_RESULT_SUCCESS)
+    {
+        pwrState = (param.curState==IARM_BUS_PWRMGR_POWERSTATE_OFF)?"PowerOFF":(param.curState==IARM_BUS_PWRMGR_POWERSTATE_ON)?"PowerON":"Standby";



The new PowerStatus implementation depends on the IARM_BUS_PWRMGR_API_GetPowerState response/mapping, but there is no unit test covering the returned strings for OFF/ON/STANDBY (or IARM call failure). Adding a gtest for get_Device_DeviceInfo_X_COMCAST_COM_PowerStatus would help prevent regressions in the state mapping.
