# Limitations Source: [https://docs.qualcomm.com/doc/80-41102-1/topic/limitations.html](https://docs.qualcomm.com/doc/80-41102-1/topic/limitations.html) ## API limitation - Transfer fd (file descriptor) between the client and server is only used for IPC, thus the APIs that contain the fd as a parameter aren't supported through TelAF RPC. - Local system resource path, like file path, directory path etc., can't be shared for remote systems, thus the APIs that contain those paths aren't supported through TelAF RPC. ## Banned services The following services aren't allowed to declare as RPC services: Table : Banned RPC services | Service name | Service user | | --- | --- | | wdog | root | | updateDaemonWdog | root | | taf\_someipSvr | telaf | | taf\_someipClnt | telaf | | taf\_ks | telaf | | taf\_fsc | telaf | | supervisorWdog | root | | sdirTool | root | | logFd | root | | logDaemonWdog | root | | LogControl | root | | LogClient | root | | le\_wdog | root | | le\_updateCtrl | root | | le\_update | root | | le\_kernelModule | root | | le\_instStat | root | | le\_ima | root | | le\_framework | root | | le\_cfgAdmin | root | | le\_cfg | root | | le\_appRemove | root | | le\_appProc | root | | le\_appInfo | root | | le\_appCtrl | root | | DeviceManagerTool | root | | DeviceManager | root | | configTreeWdog | root | **Parent Topic:** [TelAF RPC](https://docs.qualcomm.com/doc/80-41102-1/topic/rpc.html) Last Published: Aug 06, 2026 [Previous Topic Build RPC test systems and run the test application](https://docs.qualcomm.com/bundle/publicresource/80-41102-1/topics/build-rpc-test-systems-and-run-the-test-application.md) [Next Topic TelAF diagnostic](https://docs.qualcomm.com/bundle/publicresource/80-41102-1/topics/telaf_diagnostic.md)
