- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Switch the entire IPv4 stack to keep the IP packet header
in network byte order. Any host byte order processing is
done in local variables and host byte order values are
never[1] written to a packet.

After this change a packet processed by the stack isn't
modified at all[2] except for TTL.

After this change a network stack hacker doesn't need to
scratch his head trying to figure out what is the byte order
at the given place in the stack.

[1] One exception still remains. The raw sockets convert host
byte order before pass a packet to an application. Probably
this would remain for ages for compatibility.

[2] The ip_input() still subtructs header len from ip->ip_len,
but this is planned to be fixed soon.

Remove the "The option TCPDEBUG requires option INET." requirement.
In case of !INET we will not have a timestamp on the trace for now
but that might only affect spx debugging as long as INET6 requires
INET.

To my reading there are no real consumers of ip6_plen (IPv6
Payload Length) as set in tcpip_fillheaders().
ip6_output() will calculate it based of the length from the
mbuf packet header itself.
So initialize the value in tcpip_fillheaders() in correct
(network) byte order.

With the above change, to my reading, all places calling tcp_trace()
pass in the ip6 header via ipgen as serialized in the mbuf and with
ip6_plen in network byte order.
Thus convert the IPv6 payload length to host byte order before printing.

Add FBSDID to all files in netinet so that people can more
easily include file version information in bug reports.

Approved by: re (kensmith)

Rather than selectively zeroing fields in the tcp_debug structure
throughout tcp_trace(), zero the entire structure up front.

Minor style fixes.

Add global mutex tcp_debug_mtx, which will protect global TCP debugging
state tcp_debug, tcp_debx. Acquire and drop as required in tcp_trace().

Move to ANSI C function header, correct prototype types so that short TCP
state is no longer promoted to int unnecessarily.

Add comments.

Re-remove MT_TAGs. The problems with dummynet have been fixed now.

Tested by: -current, bms(mentor), me
Approved by: bms(mentor), sam

Backout MT_TAG removal (i.e. bring back MT_TAGs) for now, as dummynet is
not working properly with the patch in place.

Approved by: bms(mentor)

This set of changes eliminates the use of MT_TAG "pseudo mbufs", replacing
them mostly with packet tags (one case is handled by using an mbuf flag
since the linkage between "caller" and "callee" is direct and there's no
need to incur the overhead of a packet tag).

This is (mostly) work from: sam

It's now sufficient to rely on a nested include of _label.h to make sure
all structures in ip_var.h are defined, so remove include of mac.h.

Work to fix LINT build.

Remove a change that snuck in from my private tree.

If syncookies are disabled (net.inet.tcp.syncookies) then use the faster
arc4random() routine to generate ISNs instead of creating them with MD5().

Suggested by: silby

sync with kame tree as of july00. tons of bug fixes/improvements.

API changes:
- additional IPv6 ioctls
- IPsec PF_KEY API was changed, it is mandatory to upgrade setkey(8).
(also syntax change)

Sorry in this just befor code freeze commit.
This is fix to usr.sbin/trpt and tcp_debug.[ch]
I think of putting this after 4.0 but,,,

-There was bug that when INET6 is defined,
IPv4 socket is not traced by trpt.

-I received request from a person who distribute a program
which use tcp_debug interface and print performance statistics,
that
-leave comptibility with old program as much as possible
-use same interface with other OSes

So, I talked with itojun, and synced API with netbsd IPv6 extension.

makeworld check, kernel build check(includes GENERIC) is done.

But if there happen to any problem, please let me know and
I soon backout this change.

tcp updates to support IPv6.
also a small patch to sys/nfs/nfs_socket.c, as max_hdr size change.

$Id$ -> $FreeBSD$

Fixed printf format errors.

Make INET a proper option.

This will not make any of object files that LINT create change; there
might be differences with INET disabled, but hardly anything compiled
before without INET anyway. Now the 'obvious' things will give a
proper error if compiled without inet - ipx_ip, ipfw, tcp_debug. The
only thing that _should_ work (but can't be made to compile reasonably
easily) is sppp :-(

This commit move struct arpcom from <netinet/if_ether.h> to
<net/if_arp.h>.

Make TCPDEBUG a new-style option.

Removed unused #includes.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Eliminated sloppy common-style declarations. Now there are no duplicated
common labels for LINT. There are still some common declarations for the
!KERNEL case in tcp_debug.h and spx_debug.h. trpt depends on the ones in
tcp_debug.h.

Move or add #include <queue.h> in preparation for upcoming struct socket
changes.

New style sysctl & staticize alot of stuff.

Include <sys/queue.h> because <netinet/in_pcb.h> (also included
later in tcp_debug.c) requires it due to the pcb changes of DavidG.

NB: This has not had David's TCP ACK hack re-integrated. It is not clear
