Description Greg Lehey 2002-10-14 06:20:01 UTC
	A number of sysctl variables set in /etc/rc.network are not
	documented.  This includes variables which are set via other
	variables in /etc/rc.conf, including:

	rc.conf			   rc.network

	tcp_drop_synfin		   net.inet.tcp.drop_synfin
	tcp_restrict_rst	   net.inet.tcp.restrict_rst
				   net.inet.tcp.rfc1323
				   net.inet.tcp.rfc1644
				   net.inet.tcp.mssdflt
				   net.inet.tcp.sendspace
				   net.inet.tcp.recvspace
				   net.inet.tcp.v6mssdflt
				   net.inet.tcp.slowstart_flightsize
				   net.inet.tcp.local_slowstart_flightsize
				   net.inet.tcp.syncookies
				   net.inet.tcp.syncache.bucketlimit
				   net.inet.tcp.syncache.cachelimit   
				   net.inet.tcp.syncache.count
				   net.inet.tcp.syncache.hashsize
				   net.inet.tcp.syncache.rexmtlimit
				   net.inet.tcp.rexmit_min
				   net.inet.tcp.rexmit_slop

				   net.inet.icmp.maskrepl
				   net.inet.icmp.icmplim
	icmp_drop_redirect	   net.inet.icmp.drop_redirect
	icmp_log_redirect	   net.inet.icmp.log_redirect
				   net.inet.icmp.icmplim_output
	icmp_bmcastecho		   net.inet.icmp.bmcastecho
				   net.inet6.icmp6.rediraccept
				   net.inet6.icmp6.redirtimeout
				   net.inet6.icmp6.nd6_prune
				   net.inet6.icmp6.nd6_delay
				   net.inet6.icmp6.nd6_umaxtries
				   net.inet6.icmp6.nd6_mmaxtries
				   net.inet6.icmp6.nd6_useloopback
				   net.inet6.icmp6.nodeinfo
				   net.inet6.icmp6.errppslimit
				   net.inet6.icmp6.nd6_maxnudhint
				   net.inet6.icmp6.nd6_debug

	This is not an exhaustive list; indeed, I don't know how to
	find one.  But it's difficult to use an undocumented system,
	so we should do something about it.

	In addition, the tcp(4) man page contains descriptions of the
	(presumably obsolete) sysctls tcp.slowstart_flightsize and
	tcp.local_slowstart_flightsize.

Fix: 

This looks to be an issue for the people who implemented the
	sysctls.
How-To-Repeat: 	Create FreeBSD the way it has already been done.  Or don't
	bother trying to repeat.

This looks like a challenge.  I'll take.
