* [TCP]: Fix compile warning in tcp_probe.cDavid S. Miller2006-06-181-1/+3
| | | | | | | | The suseconds_t et al. are not necessarily any particular type on every platform, so cast to unsigned long so that we can use one printf format string and avoid warnings across the board Signed-off-by: David S. Miller <davem@davemloft.net>
* [TCP]: TCP Probe congestion window tracingStephen Hemminger2006-06-181-0/+179
This adds a new module for tracking TCP state variables non-intrusively using kprobes. It has a simple /proc interface that outputs one line for each packet received. A sample usage is to collect congestion window and ssthresh over time graphs. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
