It seems netperf has some problems zith AF_UNIX dgram :
socket(PF_FILE, SOCK_DGRAM, 0) = 4 setsockopt(4, SOL_SOCKET, SO_SNDBUF, [0], 4) = 0 getsockopt(4, SOL_SOCKET, SO_SNDBUF, [2048], [4]) = 0 setsockopt(4, SOL_SOCKET, SO_RCVBUF, [0], 4) = 0 getsockopt(4, SOL_SOCKET, SO_RCVBUF, [2288], [4]) = 0 sendto(3, "\0\0\0+\377\377\377\377\0\0\0\0\0\0\10\0\0\0\0\10\0\0\0\0\0\0\0\0\0\0\0\0"..., 256, 0, NULL, 0) = 256 select(1024, [3], NULL, NULL, {120, 0}) = 1 (in [3], left {119, 979635}) recvfrom(3, "\0\0\0,\0\0\0\0\0\0\10\360\0\0\10\0\0\0\0\0\0\0\0\n\0\0\0\0\0\0\0\0"..., 256, 0, NULL, NULL) = 256 connect(4, {sa_family=AF_FILE, path="/tmp/netpe62HGNM"}, 110) = 0 rt_sigaction(SIGALRM, {0x403171, [ALRM], SA_RESTORER|SA_INTERRUPT, 0x7f691f026af0}, NULL, 8) = 0 alarm(10) = 0 sendto(4, "netperf\0netperf\0netperf\0netperf\0"..., 2048, 0, NULL, 0) = -1 EMSGSIZE (Message too long) dup(2) = 5 fcntl(5, F_GETFL) = 0x8002 (flags O_RDWR|O_LARGEFILE) fstat(5, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 3), ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f691fa18000 lseek(5, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek) write(5, "dg_send: data send error: Messag"..., 43dg_send: data send error: Message too long ) = 43 close(5) = 0 munmap(0x7f691fa18000, 4096) = 0 exit_group(1) = ? I guess the SO_SNDBUF/SO_RCVBUF limits are a bit too low ?
Tried this on an old kernel as well.
