Same as v1, it doesn't make sense to apply this without the router. Changes since v2: - Switch xdp-forwarder build to meson - Add guest build variant of spectrum-tools Changes since v1: - rebased - apply new uncrustify config - moved xdp-forwarder to tools/ - split integration into separate commit - use linuxHeaders instead of vmlinux.h - use original xdp-tutorial {parsing,rewrite}_helpers.h - inlined the load scripts into /etc/iface/mdev, using /usr/lib/xdp as fixed prefix for finding the XDP progs - removed the README, added a paragraph to architecture doc instead Yureka Lilian (3): add xdp-forwarder integrate xdp-forwarder into net-vm docs/architecture: add paragraph about networking Documentation/about/architecture.adoc | 20 ++ pkgs/default.nix | 5 + tools/default.nix | 15 +- tools/meson.build | 5 + tools/meson_options.txt | 4 + tools/xdp-forwarder/include/parsing_helpers.h | 273 ++++++++++++++++++ tools/xdp-forwarder/include/rewrite_helpers.h | 145 ++++++++++ tools/xdp-forwarder/prog_physical.c | 37 +++ tools/xdp-forwarder/prog_router.c | 43 +++ tools/xdp-forwarder/set_router_iface.c | 32 ++ vm/sys/net/Makefile | 8 +- vm/sys/net/default.nix | 22 +- vm/sys/net/etc/fstab | 2 + vm/sys/net/etc/mdev/iface | 27 +- vm/sys/net/etc/nftables.conf | 8 - vm/sys/net/etc/s6-rc/connman/dependencies | 4 - vm/sys/net/etc/s6-rc/connman/type | 1 - vm/sys/net/etc/s6-rc/connman/type.license | 2 - vm/sys/net/etc/s6-rc/nftables/type | 1 - vm/sys/net/etc/s6-rc/nftables/type.license | 2 - vm/sys/net/etc/s6-rc/nftables/up | 6 - 21 files changed, 599 insertions(+), 63 deletions(-) create mode 100644 tools/xdp-forwarder/include/parsing_helpers.h create mode 100644 tools/xdp-forwarder/include/rewrite_helpers.h create mode 100644 tools/xdp-forwarder/prog_physical.c create mode 100644 tools/xdp-forwarder/prog_router.c create mode 100644 tools/xdp-forwarder/set_router_iface.c delete mode 100644 vm/sys/net/etc/nftables.conf delete mode 100644 vm/sys/net/etc/s6-rc/connman/dependencies delete mode 100644 vm/sys/net/etc/s6-rc/connman/type delete mode 100644 vm/sys/net/etc/s6-rc/connman/type.license delete mode 100644 vm/sys/net/etc/s6-rc/nftables/type delete mode 100644 vm/sys/net/etc/s6-rc/nftables/type.license delete mode 100644 vm/sys/net/etc/s6-rc/nftables/up -- 2.50.1
