2003-04-12 Andrew Lunn <andrew.lunn@ascom.ch> * src/network_support.c (init_loopback_interface): Close the socket when things go wrong otherwise we leak sockets. * src/tftp_server.c (tftpd_server): Added support for IPv6 as well as IPv4. Extended the multithreading support so that it works correctly when there are multiple servers on multiple ports. * doc/tcpip.sgml: Documentation for the changes made to the tftp server. 2003-04-10 Andrew Lunn <andrew.lunn@ascom.ch> * src/network_support.c (init_all_network_interfaces): Wait upto 4 seconds for a router solicit message to be received. Once we have received the message we know we have a valid IPv6 address. * src/tftp_client.c: Added support for IPv6. This requires two new functions, tftp_client_{get|put} which are protocol version independent. * tests/tftp_client_test.c (tftp_test): Added tests which use IPv6 addresses. 2003-04-07 Andrew Lunn <andrew.lunn@ascom.ch> * src/getaddrinfo.c (getaddrinfo): Correctly deal with node when its not NULL. Its OK for the address to not parse for an address family when AF_UNSPEC is passed in hints. Also get the socktype correct when wildcarding for services that use UDP. * tests/addr_test.c: Added more test cases which test IP addresses in number format as node. 2003-04-05 Andrew Lunn <andrew.lunn@ascom.ch> * cdl/net.cdl: Added addr_tests to the HW tests. * tests/addr_test.c (net_test): void function not int. * tests/ping_test.c (net_test): Added IPv6 ping test. This pings the router which answers our router solicit message. * src/ipv6_routing_thread.c (cyg_rs): Print out the router advertisement message. Cleaned up the debug messages so they can be disabled. * src/ipv6_routing_thread.c (cyg_net_get_ipv6_advrouter): New function to return the address of the router. * include/network.h: Added prototype for above and ipv6_start_routing_thread which did not have a prototype. * src/ipv6_routing_thread.c (cyg_rs): Only wait 2 seconds before sending the first solicit request rather than 10. * src/dhcp_prot.c (do_dhcp_down_net): clear the if_laddrreq before using it. If the request fails finish the IPv4 code rather than returning,. 2003-04-02 Andrew Lunn <andrew.lunn@ascom.ch> * tests/ping_lo_test.c: Added IPv6 ping test. * src/getproto.c: Added the protocol ipv6-icmp.
