version field sent via gif(4)+if_bridge(4). The EtherIP
implementation found on FreeBSD 6.1, 6.2, 6.3, 7.0, 7.1, and 7.2 had
an interoperability issue because it sent the incorrect EtherIP
packets and discarded the correct ones.
This change introduces the following two flags to gif(4):
accept_rev_ethip_ver: accepts both correct EtherIP packets and ones
with reversed version field, if enabled. If disabled, the gif
accepts the correct packets only. This flag is enabled by
default.
send_rev_ethip_ver: sends EtherIP packets with reversed version field
intentionally, if enabled. If disabled, the gif sends the correct
packets only. This flag is disabled by default.
These flags are stored in struct gif_softc and can be set by
ifconfig(8) on per-interface basis.
Note that this is an incompatible change of EtherIP with the older
FreeBSD releases. If you need to interoperate older FreeBSD boxes and
new versions after this commit, setting "send_rev_ethip_ver" is
needed.

We will look at renaming stuff for 9.0, but it's far from certain that we
will do it this way.
- Sort sysctl's alphabetically. I'll add a bunch of new sysctl's once
ariff's next mega-patch goes in, and having everything sorted makes my
job easier.
While there remain some incomplete aspects of the implementation (such
as incomplete auditing of some system calls), the implementation has
been burned in for a few years, as well as in GENERIC for a few years.

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.
get a quick snapshot of the kernel's symbol table including the symbols
from any loaded modules (the symbols are all merged into one symbol
table). Unlike like other implementations, this ksyms driver maps
memory in the process memory space to store the snapshot at the time
/dev/ksyms is opened. It also checks to see if the process has already
a snapshot open and won't allow it to open /dev/ksyms it again until it
closes first. This prevents kernel and process memory from being
exhausted. Note that /dev/ksyms is used by the lockstat(1) command.

kernel option.
This also permits tuning of the option per virtual network stack, as
well as separately per inet, inet6.
The kernel option is left for a transition period, marked deprecated,
and will be removed soon.
