8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

b1499feb9e Now that IGMP and MLD sysctls provide a clean API structures that do not
leak kernel internal stuff, reconnect ifmcstat(1) back to build.  However,
disable kvm(3) support in it, since it requires uncovering tons of _KERNEL
defined declarations, which can be achieved either uncovering them globally
or providing dirty hacks such as _WANT_IFADDR.  If anyone demands an
ifmcstat-like kvm-based tool, please take the code out of usr.sbin/ifmstat
and create a tool in src/tools/tools.

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.
