SYNOPSIS), as was threatened in the commitlog accompanying rev.

11583f6c93 Make the mb_alloc low-watermark sysctl-tunable read-only and make
netstat(1) not display it for now because its effects are not yet
completely implemented and we're about to cut 5.2-RELEASE.
This is temporary.

09139a4537 Implement support for RFC 3514 (The Security Flag in the IPv4 Header).
(See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt)

This fulfills the host requirements for userland support by
way of the setsockopt() IP_EVIL_INTENT message.

There are three sysctl tunables provided to govern system behavior.

	net.inet.ip.rfc3514:

		Enables support for rfc3514.  As this is an
		Informational RFC and support is not yet widespread
		this option is disabled by default.

	net.inet.ip.hear_no_evil

		 If set the host will discard all received evil packets.

	net.inet.ip.speak_no_evil

		If set the host will discard all transmitted evil packets.

The IP statistics counter 'ips_evil' (available via 'netstat') provides
information on the number of 'evil' packets recieved.

For reference, the '-E' option to 'ping' has been provided to demonstrate
and test the implementation.

025b4be197 o Allow "buckets" in mb_alloc to be differently sized (according to
compile-time constants).  That is, a "bucket" now is not necessarily
  a page-worth of mbufs or clusters, but it is MBUF_BUCK_SZ, CLUS_BUCK_SZ
  worth of mbufs, clusters.
o Rename {mbuf,clust}_limit to {mbuf,clust}_hiwm and introduce
  {mbuf,clust}_lowm, which currently has no effect but will be used
  to set the low watermarks.
o Fix netstat so that it can deal with the differently-sized buckets
  and teach it about the low watermarks too.
o Make sure the per-cpu stats for an absent CPU has mb_active set to 0,
  explicitly.
o Get rid of the allocate refcounts from mbuf map mess.  Instead,
  just malloc() the refcounts in one shot from mbuf_init()
o Clean up / update comments in subr_mbuf.c

a01e3379df Warns cleanups for netstat:
1) Include arpa/inet.h for ntohs.
2) Constness fixes.
3) Fix shadowing except for "sin" which shouldn't be in scope.
4) Remove register keyword.
5) Add missing initialsers to user defined structs.
5) Make prototype of netname6 globally visable.
6) Use right macros for printing syncache stats (even though entrie isn't
   a word).

f824b5187e Widen struct sockbuf's sb_timeo member to int from short. With
non-default but reasonable values of hz this member overflowed,
breaking NFS over UDP.

Also, as long as I'm plowing up struct sockbuf ... Change certain
members from u_long/long to u_int/int in order to reduce wasted
space on 64-bit machines.  This change was requested by Andrew
Gallatin.

Netstat and systat need to be rebuilt.  I am incrementing
__FreeBSD_version in case any ports need to change.

ab67591303 Use calculated column widths for the routing table display when -W is
supplied rather than arbitrarily larger widths.  This (almost) guarantees
that no columns will be truncated (routing table additions between the
width calculation and display passes may create a row with column widths
larger than those calculated).

9f5b04e925 Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

146db49f97 Fixed bugs from revision 1.27. Specifically:
- Restore the ability to look up network names in the networks(5)
  database by passing getnetbyaddr(3) shifted network numbers,
  but without duplicating the old bug that was fixed in 1.27 (we
  now only shift netnums with standard netmasks).  For example:

Before:

$ netstat -r
[...]
127.0.1/24         localhost          UGSc        0        0    lo0
127.0.2/24         localhost          UGSc        0        0    lo0

After:

$ netstat -r
[...]
subnet1/24         localhost          UGSc        0        0    lo0
subnet2/24         localhost          UGSc        0        0    lo0

- Only try to lookup with the forged netmask if the mask was not
  explicitly specified, like it was before 1.27.  For example:

Before:

$ netstat -r
net-44.ampr.org/25 localhost          UGSc        0        0    lo0
net-44.ampr.org/25 localhost          UGSc        0        0    lo0

After:

44.108.2/25        localhost          UGSc        0        0    lo0
44.108.2.128/25    localhost          UGSc        0        0    lo0

- Make sure to null-terminate the resulting string.

70a61707f6 Re-enable mbtypes statistics in the mbuf allocator. I disabled these
when I changed the allocator bits. This implements per-CPU mbtypes
stats by keeping net number of decrements/increments of a given mbtype
per-CPU and then summing all of the per-CPU mbtypes to produce the total
net number of allocated mbufs of the given mbtype.
Counters are carefully balanced to avoid/prevent underflows/overflows.

mbtypes stats are re-enabled with the idea that we may occasionally
(although very rarely) observe slight inconsistencies in the stat
reporting. Most of the time, we should be fine, though.

Also make appropriate modifications to netstat(1) and systat(1) to do
the necessary reporting.

a8a35cdd91 Add a "X KBytes of wired memory reserved" metric that represents
approximately the amount of memory allocated from the mbuf maps
and sitting in the mbuf allocator's cache containers, and display
in parantheses the percentage of said memory that is actually
in use at the given time `netstat -m' is executed.

49f854f926 - Do not handle the per-CPU containers in mbuf code as though the cpuids
were indices in a dense array. The cpuids are a sparse set and treat
  them as such, setting up containers only for CPUs activated during
  mb_init().

- Fix netstat(1) and systat(1) to treat the per-CPU stats area as a sparse
  map, in accordance with the above.

This allows us to properly boot with certain CPUs disactivated. However, if
we later decide to re-activate said CPUs, we will barf until we decide to
implement CPU spinon/spinoff callback hooks to allow for said CPUs' per-CPU
containers to get configured on their activation.
