--uds-path is set.--network-uds-path.
…ds-path`. Adds a `--network-uds-path` flag that points at an external UDS. When set: - runsc connects to that socket and donates the resulting FD to the sentry as the primary network interface instead of creating an AF_PACKET socket. - configures the primary fdbased link as an IP-only link. - the socket must be SOCK_SEQPACKET because the sentry exchanges IP packets with one packet per datagram. - `--network-uds-path` is only supported with `network=sandbox` mode. Link offload settings (such as MTU, GSO, GRO, checksum offload) are not negotiated over the socket and must be agreed out-of-band with the peer. In this mode, the external proxy connecting to the sentry should handle all the egress filtering and blocking of any traffic (if required). Runsc will forward all the traffic to that external proxy when `network-uds-path` is set. PiperOrigin-RevId: 984053710
