* sysdeps/mach/hurd/getsockname.c (getsockname): Set *LEN to the actual length if the adress length is smaller than the input value. Change type of *LEN paramater to socklen_t. * sysdeps/mach/hurd/getpeername.c (getpeername): Likewise. * sysdeps/mach/hurd/accept.c (accept): Likewise. * sysdeps/mach/hurd/recvfrom.c (recvfrom): Likewise. * sysdeps/mach/hurd/sendto.c (sendto): Change type of ADDR_LEN paramater to socklen_t.
