* slirp: replace DEBUG_ARGS with DEBUG_ARGMarc-André Lureau2019-01-141-9/+9
| | | | | | | | There is no clear benefit in calling an alias DEBUG_ARGS(). Replace calls with DEBUG_ARG(), and fix the white-spacing while at it. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
* slirp: drop <Vista compatibilityMarc-André Lureau2019-01-141-8/+6Star
| | | | | | | | | | | | | | | | Since commit 12f8def0e02232d7c6416ad9b66640f973c531d1 (v2.9), qemu requires Vista. Let's remove some conditional code. Note that this introduces a missing declaration warning with mingw. warning: implicit declaration of function 'inet_ntop' See also: https://sourceforge.net/p/mingw-w64/mailman/message/36473782/ We could workaround it by declaring it ourself depending on __MINGW64_VERSION_*: WINSOCK_API_LINKAGE INT WSAAPI inet_pton(int Family, PCTSTR pszAddrString, PVOID pAddrBuf); Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
* slirp: improve a bit the debug macrosMarc-André Lureau2019-01-141-9/+9

* slirp: Adding IPv6, ICMPv6 Echo and NDP autoconfigurationGuillaume Subiron2016-03-151-0/+90
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>
