Require all domains which can be used for BPF to be marked as bpfdomain, and add a restriction for these domains to not be able to use net_raw or net_admin. We want to make sure the network stack has exclusive access to certain BPF attach points. Bug: 140330870 Bug: 162057235 Test: build (compile-time neverallows) Change-Id: I29100e48a757fdcf600931d5eb42988101275325
