* This SNMP group of tapsets provides probes used to count SNMP managementDavid J. Wilder2009-07-163-0/+659
| | | | | | | | | | | | | | | | | | | events. The probes mirror many of the SNMP statistics defined in /usr/include/linux/snmp.h. Each probe represents a single SNMP statistic or MIB. Each of the probe's handler is called when system performs an operation that would alter the associated statistic. Along with each probe is defined an indexed set of counters used to record probe hits. The probe handlers call a user supplied callback functions to determine which counter to alter. The user's callback should returns a key value that will be used to index the counter. For example a callback could return a unique value for each socket. This would results in a separate counter being used for each socket. tcpipstat.stp shows how snmp tapsets could be used. Tcpipstat collects and displays network statistics related to individual TCP sockets or groups of sockets. The statistics that are collected are simmer to that of the command netstat -s, only sorted and grouped by individual sockets. Signed-off-by: David Wilder <dwilder@us.ibm.com>

* Add new TCP and IP functionsAndre Detsch2009-04-141-0/+12
| | | | | | | | | | | | | | | | | | | This patch adds some basic functions to the IP and TCP tapsets. Mainly, it's possible to get the iphdr and tcphdr from a sk_buff structure. As a consequence, a TCP probe called tcp.receive() was created and is probed every time a TCP packet is received, and a lot of useful fields is available, as the TCP flags. Also a small example that works like tcpdump for received TCP packets was created. This patch was tested on x86 and ppc machines, on 2.6.18 kernel and also on mainline one.
