RFC 8335 attempts to solve these limitations by creating the new utility PROBE which is a specialized ICMP message that makes use of the ICMP Extention Structure outlined in RFC 4884. This patchset adds definitions for the ICMP Extended Echo Request and Reply (PROBE) types for both IPV4 and IPV6, adds a sysctl to enable response to PROBE messages, expands the list of supported ICMP messages to accommodate PROBE types, and adds functionality to respond to PROBE requests. Changes since v1: - Add AFI definitions - Switch to functions such as dev_get_by_name and ip_dev_find to lookup net devices Andreas Roeseler (5): icmp: add support for RFC 8335 PROBE ICMPV6: add support for RFC 8335 PROBE net: add sysctl for enabling RFC 8335 PROBE messages net: add support for sending RFC 8335 PROBE messages icmp: add response to RFC 8335 PROBE messages include/net/netns/ipv4.h | 1 + include/uapi/linux/icmp.h | 24 +++++++++ include/uapi/linux/icmpv6.h | 6 +++ net/ipv4/icmp.c | 98 +++++++++++++++++++++++++++++++++---- net/ipv4/ping.c | 4 +- net/ipv4/sysctl_net_ipv4.c | 7 +++ 6 files changed, 129 insertions(+), 11 deletions(-) -- 2.25.1
