[IPV4]: Add ICMPMsgStats MIB (RFC 4293) 2007-10-10T23:51:28+00:00 David L Stevens dlstevens@us.ibm.com 2007-09-17T16:57:33+00:00 96793b482540f3a26e2188eaf75cb56b7829d3e3 Background: RFC 4293 deprecates existing individual, named ICMP type counters to be replaced with the ICMPMsgStatsTable. This table includes entries for both IPv4 and IPv6, and requires counting of all ICMP types, whether or not the machine implements the type. These patches "remove" (but not really) the existing counters, and replace them with the ICMPMsgStats tables for v4 and v6. It includes the named counters in the /proc places they were, but gets the values for them from the new tables. It also counts packets generated from raw socket output (e.g., OutEchoes, MLD queries, RA's from radvd, etc). Changes: 1) create icmpmsg_statistics mib 2) create icmpv6msg_statistics mib 3) modify existing counters to use these 4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types listed by number for easy SNMP parsing 5) modify /proc/net/snmp printing for "Icmp" to get the named data from new counters.
