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.
Changes from v6:
1/4: Update to use libslirp v4.5.0 tag
The libslirp parts of the patch have been committed to the
libslirp repo,
and are now in QEMU's copy of the libslirp repo.
Advancing QEMU to use Libslirp v4.5.0 is being done separately.
Discussion of patch 1/4 is left to that thread:
https://lists.nongnu.org/archive/html/qemu-devel/2021-05/msg06010.html
2/4: No change
3/4: Add support for --enable-slirp=system
Tested with system libslirp 4.4.0.
4/4: No change
Changes from v5:
1/4 slirp: Advance libslirp submodule to current master
NOTE TO REVIEWERS: It may be a better use of everyone's time if a
maintainer takes on advancing QEMU's libslirp to libslirp's master.
Beyond that, I really don't know what to do except submit this
patch as
is currently provided.
2/4: util/qemu-sockets.c: Split host:port parsing out of inet_parse
Also split out parsing of ipv4=on|off, ipv6=on|off
3/4: net/slirp.c: Refactor address parsing
Use InetSocketAddress and getaddrinfo().
Use new libslirp calls: slirp_remove_hostxfwd, slirp_add_hostxfwd.
4/4: net: Extend host forwarding to support IPv6
Recognize ipv4=,ipv6= options.
Note: v5's 3/5 "Recognize []:port (empty ipv6 address)" has been
deleted:
the churn on this patch series needs to be reduced.
This change is not required, and can easily be done in a later
patch.
Changes from v4:
1/5 slirp: Advance libslirp submodule to add ipv6 host-forward
support
NOTE TO REVIEWERS: I need some hand-holding to know what The Right
way to submit this particular patch is.
- no change
2/5 util/qemu-sockets.c: Split host:port parsing out of inet_parse
- move recognition of "[]:port" to separate patch
- allow passing NULL for ip_v6
- fix some formatting issues
3/5 inet_parse_host_and_addr: Recognize []:port (empty ipv6 address)
- new in this patchset revision
4/5 net/slirp.c: Refactor address parsing
- was 3/4 in v4
- fix some formatting issues
5/5 net: Extend host forwarding to support IPv6
- was 4/4 in v4
- fix some formatting issues
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
