Hello Steve,

 When I use "autrace -r" or "auditctl -a exit,always -S connect" on "ia32" machine, it report some error.
 I found in some platforms, "connect", "bind", "accept", "sendto", "recvfrom", "sendfile" isnot supported to call directly.
 They are used by syscall "socketcall".

 I think when the socket calls are supported, we should insert "socketcall" instead of them.
 Do you agree with me?
