changeset 957:db3e0a2fda2f
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.
