libslirp

libslirp is a user-mode networking library used by virtual machines, containers or various tools.

Getting Started

Prerequisites

A C compiler, meson and glib2 development libraries.

(see also .gitlab-ci.yml DEPS variable for the list of dependencies on Fedora)

Building

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)

Testing

Unfortunately, there are no automated tests available.

You may run QEMU -net user linked with your development version.

Contributing

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.

Security reports can be sent to samuel.thibault@ens-lyon.org with pgp key 900CB024B67931D40F82304BD0178C767D069EE6 (it can be found in the debian keyring for instance)

Debugging

To make slirp emit debugging prints, one can use for instance:

export G_MESSAGES_DEBUG=Slirp
export SLIRP_DEBUG=call

SLIRP_DEBUG can contain a colons/spaces/commas-separated list of call, misc, error, tftp, verbose_call

Versioning

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.
