libcamera: ipc_unixsocket: Do not run memcpy with null arguments
In IPCUnixSocket, a payload can be sent/received with empty fd vector, which leads to passing a nullptr in memcpy() in both sendData() and recvData(). Add a null check for fd vector's data pointer to avoid invoking memcpy() with nullptr. The issue is noticed by running a test manually testing the vimc IPA code paths in isolated mode. It is only noticed when the test is compiled with -Db_sanitize=address,undefined meson built-in option. ipc_unixsocket.cpp:268:8: runtime error: null pointer passed as argument 2, which is declared to never be null ipc_unixsocket.cpp:312:8: runtime error: null pointer passed as argument 1, which is declared to never be null Signed-off-by: Umang Jain <umang.jain@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
