153665ad26 show net.inet6.tcp6.* as mirror image of net.inet.tcp. better for future 
INET-less kernels.

0fe5bf8257 pipe sysctl stuff is now in <sys/pipe.h> 2001-07-02 20:55:16 +00:00

ee882e3a09 Add port of high performance pipe implementation written by John S. Dyson 
for FreeBSD project. Besides huge speed boost compared with socketpair-based
pipes, this implementation also uses pagable kernel memory instead of mbufs.

Significant differences to FreeBSD version:
* uses uvm_loan() facility for direct write
* async/SIGIO handling correct also for sync writer, async reader
* limits settable via sysctl, amountpipekva and nbigpipes available via sysctl
* pipes are unidirectional - this is enforced on file descriptor level
	for now only, the code would be updated to take advantage of it
	eventually
* uses lockmgr(9)-based locks instead of home brew variant
* scatter-gather write is handled correctly for direct write case, data
  is transferred by PIPE_DIRECT_CHUNK bytes maximum, to avoid running out of kva

All FreeBSD/NetBSD specific code is within appropriate #ifdef, in preparation
to feed changes back to FreeBSD tree.

This pipe implementation is optional for now, add 'options NEW_PIPE'
to your kernel config to use it.

4b72eeeee5 net.inet.ip.maxfragpackets defines the maximum size of ip reass queue 
(prevents fragment flood from chewing up mbuf memory space).
derived from KAME net.inet6.ip6.maxfragpackets.

83d071a318 add UBC memory-usage balancing. we track the number of pages in use for 
each of the basic types (anonymous data, executable image, cached files)
and prevent the pagedaemon from reusing a given page if that would reduce
the count of that type of page below a sysctl-setable minimum threshold.
the thresholds are controlled via three new sysctl tunables:
vm.anonmin, vm.vnodemin, and vm.vtextmin.  these tunables are the
percentages of pageable memory reserved for each usage, and we do not allow
the sum of the minimums to be more than 95% so that there's always some
memory that can be reused.

22b473e0f6 during ip6/icmp6 inbound packet processing, do not call log() nor printf() in 
normal operation (/var can get filled up by flodding bogus packets).
sysctl net.inet6.icmp6.nd6_debug will turn on diagnostic messages.
(#define ND6_DEBUG will turn it on by default)

improve stats in ND6 code.

lots of synchronziation with kame (including comments and cometic ones).

c6f45d411c Ah, so _that_'s how you get a backslash in a macro argument.

ebd0b719b0 Various formatting cleanups (mostly to use .Ql). 
Note that getting a single backslash inside Ql seems to need SIXTEEN
of them in the source!
