Functions ¶
func RunFdtransfer ¶
RunFdtransfer runs the fdtransfer command to start the fdtransfer server. Note that the client is part of the libasyncprofielr.so binary. The client connects to the fdtransfer server using a Unix domain socket and sends a request to the server for a file descriptor, specifying the type of the request (e.g., PERF_FD for perf_event_open()). The server processes the request, opens the file descriptor, and sends it back to the client using Unix domain socket with ancillary data (SCM_RIGHTS). The client receives the file descriptor and can use it for further operations.
