Perform lazy guest address resolution for IPv6 Previously QEMU rejected IPv6 host-forward attempts that had an unspecified guest address. This is because for IPv6 the guest's IP address isn't necessarily known ahead of time: Libslirp only provides a "stateless" DHCPv6 server, which if the macaddr is random then the IPv6 address is random too. This patch changes this to do the address resolution lazily, in the hopes that the guest's IPv6 address is known at the time the user wants to connect to the guest. The request can still fail if the guest doesn't have an IPv6 address yet (e.g., it's still early in the boot). Such requests are immediately rejected. Signed-off-by: Doug Evans <dje@google.com>
libslirp is a user-mode networking library used by virtual machines, containers or various tools.
A C compiler, meson and glib2 development libraries.
(see also .gitlab-ci.yml DEPS variable for the list of dependencies on Fedora)
You may build and install the shared library with meson:
meson build ninja -C build install
And configure QEMU with --enable-slirp=system to link against it.
(QEMU may build with the submodule static library using --enable-slirp=git)
Unfortunately, there are no automated tests available.
You may run QEMU -net user linked with your development version.
Feel free to open issues on the project issues page.
You may clone the gitlab project and create a merge request.
Contributing with gitlab allows gitlab workflow, tracking issues, running CI etc.
Alternatively, you may send patches to slirp@lists.freedesktop.org mailing list.
We intend to use libtool's versioning for the shared libraries and use SemVer for project versions.
For the versions available, see the tags on this repository.
