  "message": "Set reasonable defaults for our kernel\u0027s network configuration\n\nThis sets a number of sysctl options to tune the kernel for a datacenter-like environment by increasing\nbuffers and choosing a better congestion control algorithm. It also enforces reverse path filtering to\nprevent spoofing from CAP_NET_ADMIN-enabled containers and blocks source routing as we have no need for that\nand it might some day interfere with policy efforts.\n\nTo set all these options a small helper structure has been added which makes setting these more compact\nand nicer to read.\n\nTest Plan: Covered by E2E for breakage, scalability improvements not yet testable\n\nBug: T495\n\nX-Origin-Diff: phab/D704\nGitOrigin-RevId: 427b2513d604090e51b37587d772f240112be09d\n",
