Consume uBridge's ebpf_modes contract (feature/tc-window 40c36ae): a
stateful mode is usable iff ebpf=1 and its token is listed; builds
predating the field keep their shipped modes (nth/quota/flow), so the
pre-correction window semantics can never be installed silently.
- gns3server/utils/tc_capabilities.py: shared reply parser, mode
policy and filter-type mappings (compute and controller gate on the
same rules)
- gns3server/compute/ubridge/tc_probe.py: standalone probe spawning a
throwaway uBridge as the server's own user, cached by binary
identity (path/mtime/size - the version string cannot distinguish
rebuilds); failures cache as unknown
- GET /v3/compute/capabilities gains ubridge_tc {netem, ebpf,
ebpf_modes, cbpf}; the controller forwards it (Compute.capabilities)
and available_filters hides kernel-datapath filter types an endpoint
compute cannot run (both ends apply their own filters, so one
incapable compute hides the type); computes without a report keep
the full list and apply-time 409 stays the guard
- docker: _ubridge_apply_ebpf_drops gates per mode token; the cleanup
path only sends "off" for modes the build declares
- split DockerVM's kernel-datapath machinery (veth lifecycle, carrier,
marker primitives, tc filter translation, kernel NIO teardown) into
compute/docker/docker_kernel_datapath.py (DockerKernelDatapathMixin)
