Remove "prefer_source" address selection option. FreeBSD has had an
implementation of RFC 3484 for this purpose for a long time and "prefer_source"
was never implemented actually. ND6_IFF_PREFER_SOURCE macro is left intact.

Remove repeated words.

It turns out that too many drivers are not only parsing the L2/3/4
headers for TSO but also for generic checksum offloading. Ideally we
would only have one common function shared amongst all drivers, and
perhaps when updating them for IPv6 we should introduce that.
Eventually we should provide the meta information along with mbufs to
avoid (re-)parsing entirely.

To not break IPv6 (checksums and offload) and to be able to MFC the
changes without risking to hurt 3rd party drivers, duplicate the v4
framework, as other OSes have done as well.

Introduce interface capability flags for TX/RX checksum offload with
IPv6, to allow independent toggling (where possible). Add CSUM_*_IPV6
flags for UDP/TCP over IPv6, and reserve further for SCTP, and IPv6
fragmentation. Define CSUM_DELAY_DATA_IPV6 as we do for legacy IP and
add an alias for CSUM_DATA_VALID_IPV6.

This pretty much brings IPv6 handling in line with IPv4.
TSO is still handled in a different way and not via if_hwassist.

Update ifconfig to allow (un)setting of the new capability flags.
Update loopback to announce the new capabilities and if_hwassist flags.

Individual driver updates will have to follow, as will SCTP.

A major overhaul of the CARP implementation. The ip_carp.c was started
from scratch, copying needed functionality from the old implemenation
on demand, with a thorough review of all code. The main change is that
interface layer has been removed from the CARP. Now redundant addresses
are configured exactly on the interfaces, they run on.

The CARP configuration itself is, as before, configured and read via
SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or
SIOCAIFADDR_IN6 may now be configured to a particular virtual host id,
which makes the prefix redundant.

ifconfig(8) semantics has been changed too: now one doesn't need
to clone carpXX interface, he/she should directly configure a vhid
on a Ethernet interface.

To supply vhid data from the kernel to an application the getifaddrs(8)
function had been changed to pass ifam_data with each address. [1]

The new implementation definitely closes all PRs related to carp(4)
being an interface, and may close several others. It also allows
to run a single redundant IP per interface.

Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for
idea on using ifam_data and for several rounds of reviewing!

Fix several logic bugs in the previous IPv6 variable change and
re-add $ipv6_enable support for backward compatibility. From
UPDATING:

1. To use IPv6, simply define $ifconfig_IF_ipv6 like $ifconfig_IF
for IPv4. For aliases, $ifconfig_IF_aliasN should be used.
Note that both variables need the "inet6" keyword at the head.

Do not set $ipv6_network_interfaces manually if you do not
understand what you are doing. It is not needed in most cases.

$ipv6_ifconfig_IF and $ipv6_ifconfig_IF_aliasN still work, but
they are obsolete.

2. $ipv6_enable is obsolete. Use $ipv6_prefer and/or
"inet6 accept_rtadv" keyword in ifconfig(8) instead.

If you define $ipv6_enable=YES, it means $ipv6_prefer=YES and
all configured interfaces have "inet6 accept_rtadv" in the
$ifconfig_IF_ipv6. These are for backward compatibility.

3. A new variable $ipv6_prefer has been added. If NO, IPv6
functionality of interfaces with no corresponding
$ifconfig_IF_ipv6 is disabled by using "inet6 ifdisabled" flag,
and the default address selection policy of ip6addrctl(8)
is the IPv4-preferred one (see rc.d/ip6addrctl for more details).
Note that if you want to configure IPv6 functionality on the
disabled interfaces after boot, first you need to clear the flag by
using ifconfig(8) like:

ifconfig em0 inet6 -ifdisabled

If YES, the default address selection policy is set as
IPv6-preferred.

The default value of $ipv6_prefer is NO.

4. If your system need to receive Router Advertisement messages,
define "inet6 accept_rtadv" in $ifconfig_IF_ipv6. The rc(8)
scripts automatically invoke rtsol(8) when the interface becomes
UP. The Router Advertisement messages are used for SLAAC
(State-Less Address AutoConfiguration).

Document accept_rev_ethip_ver and send_rev_ethip_ver flags of
EtherIP (gif(4) + if_bridge(8)).

MFC after: 3 days

Improve flexibility of receiving Router Advertisement and
automatic link-local address configuration:

- Convert a sysctl net.inet6.ip6.accept_rtadv to one for the
default value of a per-IF flag ND6_IFF_ACCEPT_RTADV, not a
global knob. The default value of the sysctl is 0.

- Add a new per-IF flag ND6_IFF_AUTO_LINKLOCAL and convert a
sysctl net.inet6.ip6.auto_linklocal to one for its default
value. The default value of the sysctl is 1.

- Make ND6_IFF_IFDISABLED more robust. It can be used to disable
IPv6 functionality of an interface now.

- Receiving RA is allowed if ip6_forwarding==0 *and*
ND6_IFF_ACCEPT_RTADV is set on that interface. The former
condition will be revisited later to support a "host + router" box
like IPv6 CPE router. The current behavior is compatible with
the older releases of FreeBSD.

- The ifconfig(8) now supports these ND6 flags as well as "nud",
"prefer_source", and "disabled" in ndp(8). The ndp(8) now
supports "auto_linklocal".

Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

More information at: http://wiki.freebsd.org/WifiMesh

Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.

Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.

Add the "Monitor" interface flag.

Setting this flag on an ethernet interface blocks transmission of packets
and discards incoming packets after BPF processing.

This is useful if you want to monitor network trafic but not interact
with the network in question.

Implement user-setable promiscuous mode (a new `promisc' flag for ifconfig(8)).
Also, for all interfaces in this mode pass all ethernet frames to upper layer,
even those not addressed to our own MAC, which allows packets encapsulated
in those frames be processed with packet filters (ipfw(8) et al).

Restore (sorta) a useful piece of information that got lost in the
previous delta -- an ability to specify /prefixlength after an IPv6

In the words of the submitter:

The first "synopsis" example has a "[/prefixlength]" which shouldn't
be there, since that stuff is part of the preceeding "address" as is
explained in the description of "address".

(The way it is now, 192.168.0.1/16/prefixlength would be a proper
operand. Note that "prefixlength" is not mentioned by name anywhere.)

Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it

When using interfaces that support if_media, the supported media list is
printed on a single, very long, and generally unreadable line. This
isn't very useful. It's also really ugly and most of the time you don't
care what media is supported anyway.

Currently, each wireless networking driver has it's own control program
despite the fact that most people want to set exactly the same settings
regardless of which card they have. It has been repeatidly suggested

wi and an drivers. It also provides partial, untested support for the

Note that "ether" is a supported address family for setting addresses.

Implement SIOCSIFLLADDR, which allows you to change the link-level
address on an interface. This basically allows you to do what my
little setmac module/utility does via ifconfig. This involves the
following changes:

socket.h: define SIOCSIFLLADDR
if.c: add support for SIOCSIFLLADDR, which resets the values in
the arpcom struct and sockaddr_dl for the specified interface.
Note that if the interface is already up, we need to down/up
it in order to program the underlying hardware's receive filter.
ifconfig.c: add lladdr command
ifconfig.8: document lladdr command

You can now force the MAC address on any ethernet interface to be
whatever you want. (The change is not sticky across reboots of course:
we don't actually reprogram the EEPROM or anything.) Actually, you
can reprogram the MAC address on other kinds of interfaces too; this
shouldn't be ethernet-specific (though at the moment it's limited to
6 bytes of address data).

Nobody ran up to me and said "this is the politically correct way to
do this!" so I don't want to hear any complaints from people who think
I could have done it more elegantly. Consider yourselves lucky I didn't
do it by having ifconfig tread all over /dev/kmem.

Document "-alias".

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Spelling: ``adress'' -> ``address''

Introduce ``add'' and ``remove'' as alternatives to ``alias'' and ``delete''.
Improve compatibility with BSD/OS, and also more accurately reflect that
IP aliases aren't really any different than the primary IP address on an
interface.
