2019-01-14slirp: call into g_debug() for DEBUG macrosMarc-André Lureau1-3/+2
Make slirp use GLib logging, instead of fprintf(), so that applications can filter log, process it etc. With recent versions of glib, G_MESSAGES_DEBUG must be set to "all" or "Slirp" to see slirp debug messages. Reformat DEBUG_MISC & DEBUG_ERROR calls to not need \n ending. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
2019-01-14slirp: use %p for pointers formatMarc-André Lureau1-3/+3
This fixes some compilation warnings on mingw64. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
2019-01-14slirp: improve a bit the debug macrosMarc-André Lureau1-3/+3
Let them accept multiple arguments. Simplify the inner argument handling of DEBUG_ARGS/DEBUG_MISC_DEBUG_ERROR. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
2018-11-10slirp: Remove code that handles socreate() failurePeter Maydell1-3/+0
Now that socreate() can never fail, we can remove the code that was trying to handle that situation. In particular this removes code in tcp_connect() that provoked Coverity to complain (CID 1005724): in closesocket(accept(inso->s, (struct sockaddr *)&addr, &addrlen)); if the accept() call fails then we pass closesocket() -1 instead of a valid file descriptor.

2016-07-03slirp: Add support for stateless DHCPv6Thomas Huth1-1/+12
Provide basic support for stateless DHCPv6 (see RFC 3736) so that guests can also automatically boot via IPv6 with SLIRP (for IPv6 network booting, see RFC 5970 for details). Tested with: qemu-system-ppc64 -nographic -vga none -boot n -net nic \ -net user,ipv6=yes,ipv4=no,tftp=/path/to/tftp,bootfile=ppc64.img Signed-off-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Samuel Thibault <samuel.thibault@ens-lyon.org>
2016-05-16slirp: Clean up osdep.h related header inclusionsThomas Huth1-1/+0
qemu/osdep.h is included in some headers twice - one time should be sufficient. Also remove the inclusion of time.h since that is already done by osdep.h, too (this makes scripts/clean-includes happy again).

2016-03-15slirp: Add IPv6 support to the TFTP codeThomas Huth1-3/+13
Add the handler code for incoming TFTP packets to udp6_input(), and make sure that the TFTP code can send packets with both, udp_output() and udp6_output() by introducing a wrapper function called tftp_udp_output().

2016-03-15slirp: Adding IPv6 UDP supportGuillaume Subiron1-0/+159
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().
