[PATCH v4 0/4] Add support for ipv6 host forwarding |
Date: |

This patchset takes the original patch from Maxim,
https://www.mail-archive.com/qemu-devel@nongnu.org/msg569573.html
and updates it.
Option hostfwd is extended to support ipv6 addresses.
Commands hostfwd_add, hostfwd_remove are extended as well.
The libslirp part of the patch has been committed upstream,
and is now in qemu. See patch 1/4.
Changes from v3:
1/4 slirp: Advance libslirp submodule to add ipv6 host-forward support
- pick up latest libslirp patch to reject ipv6 addr-any for guest address
- libslirp currently only provides a stateless DHCPv6 server, which means
it can't know in advance what the guest's IP address is, and thus
cannot do the "addr-any -> guest ip address" translation that is done
for ipv4
2/4 util/qemu-sockets.c: Split host:port parsing out of inet_parse
- this patch is new in v4
- provides new utility: inet_parse_host_and_port, updates inet_parse
to use it
3/4 net/slirp.c: Refactor address parsing
- this patch renamed from 2/3 to 3/4
- call inet_parse_host_and_port from util/qemu-sockets.c
- added tests/acceptance/hostfwd.py
4/4 net: Extend host forwarding to support IPv6
- this patch renamed from 3/3 to 4/4
- ipv6 support added to existing hostfwd option, commands
- instead of creating new ipv6 option, commands
- added tests to tests/acceptance/hostfwd.py
Changes from v2:
- split out libslirp commit
- clarify spelling of ipv6 addresses in docs
- tighten parsing of ipv6 addresses
Change from v1:
- libslirp part is now upstream
- net/slirp.c changes split into two pieces (refactor, add ipv6)
- added docs
