This problem has existed since the\nintroduction of net namespaces.\n\nThe current logic marks them read-only only if the net namespace is\nowned by an unprivileged user (other than init_user_ns).\n\nCommit d0febd81ae77 (\"netfilter: conntrack: re-visit sysctls in\nunprivileged namespaces\") \"exposes all sysctls even if the namespace is\nunpriviliged.\" Since we need to mark them readonly in any case, we can\nforego the unprivileged user check altogether.",
