10fa36f0bc o in6_ifinfo() does not do any kvm(3) operations, so
do not guard it by WITH_KVM ifdef.  This allows to build
ifmcstat(8) without kvm(3) support.

29dc7bc636 Merge final round of MLD changes from p4:
ip6_input.c, in6.h:
 * Add netinet6-specific mbuf flag M_RTALERT_MLD, shadowing M_PROTO6.
  * Always set this flag if HBH Router Alert option is present for MLD,
    even when not forwarding.

 icmp6.c:
 * In icmp6_input(), spell m->m_pkthdr.rcvif as ifp to be consistent.
 * Use scope ID for verifying input. Do not apply SSM filters here, no inpcb.
  * Check for M_RTALERT_MLD when validating MLD traffic, as we can't see
    IPv6 hop options outside of ip6_input().

 in6_mcast.c:
 * Use KAME scope/zone ID in in6_multi.
   * Update net.inet6.ip6.mcast.filters implementation to use scope IDs
     for comparisons.
 * Fix scope ID treatment in multicast socket option processing.
   Scope IDs passed in from userland will be ignored as other less
   ambiguous APIs exist for specifying the link.
 * Tighten userland input checks in IPv6 SSM delta and full-state ops.
   * Source filter embedded scope IDs need to be revisited, for now
     just clear them and ignore them on input.
 * Adapt KAME behaviour of looking up the scope ID in the default zone
   for multicast leaves, when the interface is ambiguous.

 mld6.c:
 * Tighten origin checks on MLD traffic as per RFC3810 Section 6.2:
  * ip6_src MAY be the unspecified address for MLDv1 reports.
  * ip6_src MAY have link-local address scope for MLDv1 reports,
    MLDv1 queries, and MLDv2 queries.
  * Perform address field validation *before* accepting queries.
 * Use KAME scope/zone ID in query/report processing.
   * Break const correctness for mld_v1_input_report(), mld_v1_input_query()
     as we temporarily modify the input mbuf chain.
   * Clear the scope ID before handoff to userland MLD daemon.
 * Fix MLDv1 old querier present timer processing.
   With the protocol defaults, hosts should revert to MLDv2 after 260s.
 * Add net.inet6.mld.v1enable sysctl, default to on.

 ifmcstat.c:
 * Use sysctl by default; -K requests kvm(3) if so compiled.

 mld.4:
 * Connect man page to build.

Tested using PCS.

33cde13046 Bite the bullet, and make the IPv6 SSM and MLDv2 mega-commit:
import from p4 bms_netdev.  Summary of changes:

 * Connect netinet6/in6_mcast.c to build.
   The legacy KAME KPIs are mostly preserved.
 * Eliminate now dead code from ip6_output.c.
   Don't do mbuf bingo, we are not going to do RFC 2292 style
   CMSG tricks for multicast options as they are not required
   by any current IPv6 normative reference.
 * Refactor transports (UDP, raw_ip6) to do own mcast filtering.
   SCTP, TCP unaffected by this change.
 * Add ip6_msource, in6_msource structs to in6_var.h.
 * Hookup mld_ifinfo state to in6_ifextra, allocate from
   domifattach path.
 * Eliminate IN6_LOOKUP_MULTI(), it is no longer referenced.
   Kernel consumers which need this should use in6m_lookup().
 * Refactor IPv6 socket group memberships to use a vector (like IPv4).
 * Update ifmcstat(8) for IPv6 SSM.
 * Add witness lock order for IN6_MULTI_LOCK.
 * Move IN6_MULTI_LOCK out of lower ip6_output()/ip6_input() paths.
 * Introduce IP6STAT_ADD/SUB/INC/DEC as per rwatson's IPv4 cleanup.
 * Update carp(4) for new IPv6 SSM KPIs.
 * Virtualize ip6_mrouter socket.
   Changes mostly localized to IPv6 MROUTING.
 * Don't do a local group lookup in MROUTING.
 * Kill unused KAME prototypes in6_purgemkludge(), in6_restoremkludge().
 * Preserve KAME DAD timer jitter behaviour in MLDv1 compatibility mode.
 * Bump __FreeBSD_version to 800084.
 * Update UPDATING.

NOTE WELL:
 * This code hasn't been tested against real MLDv2 queriers
   (yet), although the on-wire protocol has been verified in Wireshark.
 * There are a few unresolved issues in the socket layer APIs to
   do with scope ID propagation.
 * There is a LOR present in ip6_output()'s use of
   in6_setscope() which needs to be resolved. See comments in mld6.c.
   This is believed to be benign and can't be avoided for the moment
   without re-introducing an indirect netisr.

This work was mostly derived from the IGMPv3 implementation, and
has been sponsored by a third party.

d10910e6ce Merge IGMPv3 and Source-Specific Multicast (SSM) to the FreeBSD
IPv4 stack.

Diffs are minimized against p4.
PCS has been used for some protocol verification, more widespread
testing of recorded sources in Group-and-Source queries is needed.
sizeof(struct igmpstat) has changed.

__FreeBSD_version is bumped to 800070.

d508ff40b9 Improve ifmcstat(8) and fix a few bugs while we're at it:
* Retire the old 'ifmcstat <kernel>' usage.
 * Print AF_LINK records even if run against KVM.
   This makes the KVM backend consistent with the sysctl backend.
 * Suppress printing of link-layer group records by default.
 * Add a -v switch to allow link-layer groups to be printed.
 * If compiled without INET6 support, actually work.
 * If compiled with INET6 support, print the scope ID of
   all IPv6 addresses in both backends.
 * Update man page.
 * Update copyrights.

With this change, it is now reasonable to retire netstat -g.
Most of the SSM related gunk in this file will require later refactoring.

60dd8da775 Considerably rework the ifmcstat utility.
* Build with or without INET, INET6, or KVM features.
  * When built without KVM, the sysctl-based getifmaddrs() function
    is used as the back-end for the utility.
 * Reflect the fact that FreeBSD now uses the in_multi refcount as
   a true refcount.
 * Style.

The utility may now be run without super-user privilege, albeit with
a less detailed display, equivalent to that of the soon-to-be-retired
netstat -g host-mode output.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.
