hi, Just do some debugging, and found something. I hope this do help. Correct me if anything wrong.
I'm using samba-3.2.2. For some reason, Linux can not splice a socket and a filefd directly, which samba does so. In linux, sys_splice calls do_splice, which would require either in or out fd to be a PIPE(FIFO). Both parameter (fromfd, tofd) that samba sent with splice failed the test S_ISFIFO() in linux. Maybe it would work to add an addition FIFO? splice(fromfd, FIFO) and splice(FIFO, tofd)?
