All values are explicitly checked for correctness before usage.
Default values for those variables represent current/legacy port

Hello,
You can look at http://www.rtems.com/ Their TCP/IP stack is derived
from FreeBSD and is probably better suited for 'extraction' than
current FreeBSD TCP/IP implementation. Also, the QNX public SVN
repository should contain QNX's fork of the NetBSD network stack as
separate resource manager.
Hello,
Great project! But could you please elaborate on technologies being used in it?
Thank you very much in advance.

Hello all,
I'm currently working on some ipv6 related code. At some point I have
to do a routing lookup and I meet following problem:
panic: mtx_lock() of spin mutex 'some_strange_chars' ../../../net/route.c:114
cpuid = 0
KDB: enter: panic
[thread pid 17 tid 100021 ]
Stopped at kdb_enter+0x3
Actually there is:
struct route_in6 ip6_forward_rt;
that "caches" the last route used (thanks blue !!!) but i think this
technique is pointless in a multiflow traffic.
Is it reasonable to believe that route caches can improve networking
performance or we should leave it up to the routing table
Hello all,
I find this:
. . .
/*
* Try to forward a packet based on the destination address.
* This is a fast path optimized for the plain forwarding case.
* If the packet is handled (and consumed) here then we return 1;
* otherwise 0 is returned and the packet should be delivered
* to ip_
Does FreeBSD rtalloc*() (or any other) functions implement route
caching and how ? I looked at the code but it's not exactly easiest
thing to read / understand :)

I'm not familiar with bittorrent protocol but I guess you can always
implement simple L7 filter using ipfw rules to divert packets to a custom
daemon that can parse the data and drop torrent packets. I did something
similar for ICQ several years ago.
