AF_PACKET support for netstack (aka epsocket). Like (AF_INET, SOCK_RAW) sockets, AF_PACKET sockets require CAP_NET_RAW. With runsc, you'll need to pass `--net-raw=true` to enable them. Binding isn't supported yet. PiperOrigin-RevId: 275909366
Netstack is a network stack written in Go.
Try it out on Linux by installing the tun_tcp_echo demo:
go install github.com/google/netstack/tcpip/sample/tun_tcp_echo
Create a TUN device with:
[sudo] ip tuntap add user <username> mode tun <device-name> [sudo] ip link set <device-name> up [sudo] ip addr add <ipv4-address>/<mask-length> dev <device-name>
Then run with:
tun_tcp_echo <device-name> <ipv4-address> <port>
Please see CONTRIBUTING.md for more details.
Netstack is primarily developed as part of gVisor and any issues/bugs should be filed against the gVisor repository as this repo is not actively monitored for bug reports.
This is not an official Google product (experimental or otherwise), it is just code that happens to be owned by Google.
