Allow unprivileged users to use: /proc/sys/net/ipv4/icmp_echo_ignore_all /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts /proc/sys/net/ipv4/icmp_ignore_bogus_error_response /proc/sys/net/ipv4/icmp_errors_use_inbound_ifaddr /proc/sys/net/ipv4/icmp_ratelimit /proc/sys/net/ipv4/icmp_ratemask /proc/sys/net/ipv4/ping_group_range /proc/sys/net/ipv4/tcp_ecn /proc/sys/net/ipv4/ip_local_ports_range These are occassionally handy and after a quick review I don't see any problems with unprivileged users using them.
