2016-04-01slirp: Allow disabling IPv4 or IPv6Samuel Thibault
Add ipv4 and ipv6 boolean options, so the user can setup IPv4-only and IPv6-only network environments. Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Reviewed-by: Thomas Huth <thuth@redhat.com>
2016-03-15slirp: Handle IPv6 in TCP functionsGuillaume Subiron
This patch adds IPv6 case in TCP functions refactored by the last patches. This also adds IPv6 pseudo-header in tcpiphdr structure. Finally, tcp_input() is called by ip6_input().

2016-03-15slirp: Adding IPv6 UDP supportGuillaume Subiron
This adds the sin6 case in the fhost and lhost unions and related macros. It adds udp6_input() and udp6_output(). It adds the IPv6 case in sorecvfrom(). Finally, udp_input() is called by ip6_input().

2016-03-15slirp: Adding ICMPv6 error sendingYann Bordenave
Adding icmp6_send_error to send ICMPv6 Error messages. This function is simpler than the v4 version. Adding some calls in various functions to send ICMP errors, when a received packet is too big, or when its hop limit is 0.

2016-03-15slirp: Fix ICMP error sendingYann Bordenave
Disambiguation : icmp_error is renamed into icmp_send_error, since it doesn't manage errors, but only sends ICMP Error messages. Signed-off-by: Yann Bordenave <meow@meowstars.org> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Reviewed-by: Thomas Huth <thuth@redhat.com>
2016-03-15slirp: Adding IPv6, ICMPv6 Echo and NDP autoconfigurationGuillaume Subiron
This patch adds the functions needed to handle IPv6 packets. ICMPv6 and NDP headers are implemented. Slirp is now able to send NDP Router or Neighbor Advertisement when it receives Router or Neighbor Solicitation. Using a 64bit-sized IPv6 prefix, the guest is now able to perform stateless autoconfiguration (SLAAC) and to compute its IPv6 address. This patch adds an ndp_table, mainly inspired by arp_table, to keep an NDP cache and manage network address resolution. Slirp regularly sends NDP Neighbor Advertisement, as recommended by the RFC, to make the guest refresh its route. This also adds ip6_cksum() to compute ICMPv6 checksums using IPv6 pseudo-header. Some #define ETH_* are moved upper in slirp.h to make them accessible to other slirp/*.h Signed-off-by: Guillaume Subiron <maethor@subiron.org> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Reviewed-by: Thomas Huth <thuth@redhat.com>
