This was tested with: https://github.com/rafaeldtinoco/drafts/tree/net-tests
And it picks sockets created for all tasks within the attached cgroup fd:

33 tasks

I'm not adding a selftest yet because I want to first finish the proof-of-concept and check if there are any other needs. Then I'll create a simple selftest for the cgroup attachment feature (after this PR). |

Create AttachCgroup(string) to allow the following program types: - BPF_PROG_TYPE_CGROUP_SKB - BPF_PROG_TYPE_CGROUP_SOCK - BPF_PROG_TYPE_CGROUP_DEVICE - BPF_PROG_TYPE_CGROUP_SOCK_ADDR - BPF_PROG_TYPE_CGROUP_SYSCTL - BPF_PROG_TYPE_CGROUP_SOCKOPT to be attached to a cgroupv2 directory file descriptor, such as: - /sys/fs/cgroup/unified - /sys/fs/cgroup/unified/user.slice/user-1000.slice and on... Those eBPF program types will be triggered for all processes within the cgroupv2 they were attached to.
