count successful path MTU changes. good for debugging.
...
(there could be some discussion on when to increase the counter...)

nuke the following sysctl variables. "ppsratelimit" should work better.
...
need to recompile sbin/sysctl after updating /usr/include.
net.inet.tcp.rstratelimit
net.inet.icmp.errratelimit
net.inet6.icmp6.errratelimit
2000-07-28 04:06:52 +00:00

implement net.inet.icmp.errppslimit.
...
make default value for net.inet.icmp.erratelimit to 0, as < 10ms value
does not do the right thing.

add icmpreturndatabytes kernel variable (default 8) which specifies the
...
number of extra data bytes to return in ICMP error messages. This is
also available via sysctl as net.icmp.returndatabytes and is limited to
[8,512].

f3b975e9a4
Add ICMP error rate limiting, based on the same for ICMP6.
...
Note, we're reusing the previously unused slot for "MTU discovery" (which
was moved to the "net.inet.ip" branch of the sysctl tree quite some time
ago).

Update protocoles and interfaces stats counters to 64bit.
...
RTM_IFINFO is now 0xf, 0xe is RTM_OIFINFO which returns the old (if_msghdr14)
struct with 32bit counters (binary compat, conditioned on COMPAT_14).
Same for sysctl: node 3 is renamed NET_RT_OIFLIST, NET_RT_IFLIST is now node 4.
Change rt_msg1() to add an mbuf to the mbuf chain instead of just panic()
when the message is larger than MHLEN.

323c04642b
Path MTU Discovery support. This is turned off by default.
...
Use sysctl -w net.inet.icmp.mtudisc=1 to turn on.
Still to come: path removal after some period, black hole detection
