libstat status 9

[Gabor PALI]

Hi there,

Here is a short summary of the progress of the last week:

- Finished adding the various protocol-dependent statistics to the
libnetstat library (and using them in netstat(1)): icmp6, rip6, pim6,
ipx, spx, pfsync, pfkey, ipsec (ah, esp, ipcomp), ip6, mroute, mroute6
(multicast forwarding), route (forwarding) statistics.  Because they
are now extracted via the "framework" reported last week, all of them
can be retrieved from both kernel images and live systems (via
sysctl(3)), and can be reset.

- Added an abstraction for handling sessions ("session_type", it was
previously suggested by Robert) -- at the moment, it does not include
too much, only a kvm(3) handle, but it could be used for adding other
state-related information, so it is suitable for working with
virtualized network stack instances.  However, in my opinion, this
abstraction also contributes to a cleaner implementation in the
modified applications.

Cheers,
