The default Linux Capabilities set enabled by the docker, exec, and java task drivers includes CAP_NET_RAW (for making ping just work), which has the side affect of opening an ARP DoS/MiTM attack between tasks using bridge networking on the same host network. https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities This PR disables CAP_NET_RAW for the docker, exec, and java task drivers. The previous behavior can be restored for docker using the allow_caps docker plugin configuration option. A future version of nomad will enable similar configurability for the exec and java task drivers. |
