We do not respect rules 3 and 4 in the required list:
1. omit leading zeros
2. "::" used to their maximum extent whenever possible
3. "::" used where shortens address the most
4. "::" used in the former part in case of a tie breaker
5. do not shorten one 16 bit 0 field
6. use lower case

"Whitspace" churn after the VIMAGE/VNET whirls.
Remove the need for some "init" functions within the network
stack, like pim6_init(), icmp_init() or significantly shorten
others like ip6_init() and nd6_init(), using static initialization
again where possible and formerly missed.
Move (most) variables back to the place they used to be before the
container structs and VIMAGE_GLOABLS (before r185088) and try to
reduce the diff to stable/7 and earlier as good as possible,
to help out-of-tree consumers to update from 6.x or 7.x to 8 or 9.
This also removes some header file pollution for putatively
static global variables.
Revert VIMAGE specific changes in ipfilter::ip_auth.c, that are
no longer needed.

that we allow all possible jail IPs as source address rather than
forcing the "primary". While IPv6 naturally has source address
selection, for legacy IP we do not go through the pain in case
IP_HDRINCL was not set. People should bind(2) for that.
This will, for example, allow ping(|6) -S to work correctly for
non-primary addresses.

prevented the link-layer entry from being freed.
In both in.c and in6.c (though that code path seems to be basically dead)
plug a reference leak in case of a pending callout being drained.
In if_ether.c consistently add a reference before resetting the callout
and in case we canceled a pending one remove the reference for that.
In the final case in arptimer, before freeing the expired entry, remove
the reference again and explicitly call callout_stop() to clear the active
flag.
In nd6.c:nd6_free() we are only ever called from the callout function and
thus need to remove the reference there as well before calling into
llentry_free().
In if_llatbl.c when freeing entire tables make sure that in case we cancel
a pending callout to remove the reference as well.

have the delayed function take an argument as to the offset
to the SCTP header. This allows it to work for V4 and V6.
This of course means changing all callers of the function
to either pass the header len, if they have it, or create
it (ip_hl << 2 or sizeof(ip6_hdr)).

no delayed checksum was added to the ip6 output code. This
causes cards that do not support SCTP checksum offload to
have SCTP packets that are IPv6 NOT have the sctp checksum
performed. Thus you could not communicate with a peer. This
adds the missing bits to make the checksum happen for these cards.

whether to use source address selection (default) or the primary
jail address for unbound outgoing connections.
This is intended to be used by people upgrading from single-IP
jails to multi-IP jails but not having to change firewall rules,
application ACLs, ... but to force their connections (unless
otherwise changed) to the primry jail IP they had been used for
years, as well as for people prefering to implement similar policies.
Note that for IPv6, if configured incorrectly, this might lead to
scope violations, which single-IPv6 jails could as well, as by the
design of jails. [1]

for the interface address. This marker is necessary to properly support
PPP types of links where multiple links can have the same local end
IP address. The IFA_RTSELF flag bit maps to the RTF_HOST value, which
was combined into the route flag bits during prefix installation in
IPv6. This inclusion causing the prefix route to be unusable. This
patch fixes this bug by excluding the IFA_RTSELF flag during route
installation.

same interface. The first address will install the prefix route into
the kernel routing table and that prefix will be marked as on-link.
Without RADIX_MPATH enabled, the other address aliases of the same
prefix will update the prefix reference count but no other routes
will be installed. Consequently the prefixes associated with these
addresses would not be marked as on-link. As such, incoming packets
destined to these address aliases will fail the ND6 on-link check
on input. This patch fixes the above problem by searching the kernel
routing table and try to find an on-link prefix on the given interface.

IFF_POINTOPOINT link types. The reason was due to the routing
entry returned from the kernel covering the remote end is of an
interface type that does not support ARP. This patch fixes this
problem by providing a hint to the kernel routing code, which
indicates the prefix route instead of the PPP host route should
be returned to the caller. Since a host route to the local end
point is also added into the routing table, and there could be
multiple such instantiations due to multiple PPP links can be
created with the same local end IP address, this patch also fixes
the loopback route installation failure problem observed prior to
this patch. The reference count of loopback route to local end would
be either incremented or decremented. The first instantiation would
create the entry and the last removal would delete the route entry.

left. If you are running with a vnet (virtual network stack) those will
return true and defer you to classic IP-jails handling and thus things
will be "denied" or returned with an error.
Work around this problem by introducing another "jailed()" function,
jailed_without_vnet(), that also takes vnets into account, and permits
the calls, should the jail from the given cred have its own virtual
network stack.
We cannot change the classic jailed() call to do that, as it is used
outside the network stack as well.

Don't allow joins w/o source on an existing group.
This is almost always pilot error.
We don't need to check for group filter UNDEFINED state at t1,
because we only ever allocate filters with their groups, so we
unconditionally reject such calls with EINVAL.
Trying to change the active filter mode w/o going through IPV6_MSFILTER
is also disallowed.

Tighten input checking in in6p_join_group():
* Don't try to use the source address, when its family is unspecified.
* If we get a join without a source, on an existing inclusive
mode group, this is an error, as it would change the filter mode.
Fix a problem with the handling of in6_mfilter for new memberships:
* Do not rely on im6f being NULL; it is explicitly initialized to a
non-NULL pointer when constructing a membership.
* Explicitly initialize *im6f to EX mode when the source address
is unspecified.
This fixes a problem with in_mfilter slot recycling in the join path.

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".
