/*
 * This is regression test for COMPAT_43 code. Tested 4.3 syscalls are:
 * - getsockname(2), getpeername(2)
 * - recv(2), recvfrom(2), recvmsg(2)
 * - send(2), sendmsg(2)
 *
 * This program uses inetd echo service. You need to configure
 * inetd to provide echo for both tcp and udp in order to run
 * this program successfully, and adjust 'echoserver' to IP address
 * of the machine running the service.
 *
 * Public domain. Do whatever you please with this. Jaromir Dolecek
