@ -983,6 +983,13 @@ ip_early_demux - BOOLEAN
reduces overall throughput, in such case you should disable it.
Default: 1
ping_group_range - 2 INTEGERS
Restrict ICMP_PROTO datagram sockets to users in the group range.
The default is "1 0", meaning, that nobody (not even root) may
create ping sockets. Setting it to "100 100" would grant permissions
to the single group. "0 4294967295" would enable it for the world, "100
4294967295" would enable it for the users, but not daemons.
tcp_early_demux - BOOLEAN
Enable early demux for established TCP sockets.
