| | | | | | | | | | | | | | | | | | | | | | | | * librelay.h: Get structs and enums from ../transport/transport_msgs.h to eliminate duplication. * librelay.c (send_request): Retry if send fails. (open_relayfs_files): Use fopen() instead of open() for the percpu tmpfiles. (request_last_buffers): Just send cpu number for STP_BUF_INFO request. (reader_thread): Ditto. (process_subbufs): Use fwrite_unlocked() instead of write(). (sigchld): Removed. (init_stp): Go back to using system() instead of fork and exec to load module.

(stp_main_loop): When receiving STP_TRANSPORT_INFO, set the local params and reply with a STP_START. When receiving STP_START, there was an error, so cleanup and exit. * stpd.c (main): Added new options to set number of buffers and their size.
