    ipv6: Add icmp_echo_ignore_all support for ICMPv6 · e6f86b0f
    Virgile Jarry authored
    Preventing the kernel from responding to ICMP Echo Requests messages
    can be useful in several ways. The sysctl parameter
    'icmp_echo_ignore_all' can be used to prevent the kernel from
    responding to IPv4 ICMP echo requests. For IPv6 pings, such
    a sysctl kernel parameter did not exist.
    
    Add the ability to prevent the kernel from responding to IPv6
    ICMP echo requests through the use of the following sysctl
    parameter : /proc/sys/net/ipv6/icmp/echo_ignore_all.
    Update the documentation to reflect this change.
