The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

Adapt r197135 to IPv6 stack: 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.

Adapt r197132 to IPv6 stack: 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.

Build on Jeff Roberson's linker-set based dynamic per-CPU allocator (DPCPU), as suggested by Peter Wemm, and implement a new per-virtual network stack memory allocator. Modify vnet to use the allocator instead of monolithic global container structures (vinet, ...). This change solves many binary compatibility problems associated with VIMAGE, and restores ELF symbols for virtualized global variables.
Each virtualized global variable exists as a "reference copy", and also once per virtual network stack. Virtualized global variables are tagged at compile-time, placing the in a special linker set, which is loaded into a contiguous region of kernel memory. Virtualized global variables in the base kernel are linked as normal, but those in modules are copied and relocated to a reserved portion of the kernel's vnet region with the help of a the kernel linker.
Virtualized global variables exist in per-vnet memory set up when the network stack instance is created, and are initialized statically from the reference copy. Run-time access occurs via an accessor macro, which converts from the current vnet and requested symbol to a per-vnet address. When "options VIMAGE" is not compiled into the kernel, normal global ELF symbols will be used instead and indirection is avoided.
This change restores static initialization for network stack global variables, restores support for non-global symbols and types, eliminates the need for many subsystem constructors, eliminates large per-subsystem structures that caused many binary compatibility issues both for monitoring applications (netstat) and kernel modules, removes the per-function INIT_VNET_*() macros throughout the stack, eliminates the need for vnet_symmap ksym(2) munging, and eliminates duplicate definitions of virtualized globals under VIMAGE_GLOBALS.
Bump __FreeBSD_version and update UPDATING.

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.

Permit buiding kernels with options VIMAGE, restricted to only a single active network stack instance. Turning on options VIMAGE at compile time yields the following changes relative to default kernel build:
1) V_ accessor macros for virtualized variables resolve to structure fields via base pointers, instead of being resolved as fields in global structs or plain global variables. As an example, V_ifnet becomes:
options VIMAGE: ((struct vnet_net *) vnet_net)->_ifnet default build: vnet_net_0._ifnet options VIMAGE_GLOBALS: ifnet
2) INIT_VNET_* macros will declare and set up base pointers to be used by V_ accessor macros, instead of resolving to whitespace:
INIT_VNET_NET(ifp->if_vnet); becomes
struct vnet_net *vnet_net = (ifp->if_vnet)->mod_data[VNET_MOD_NET];
3) Memory for vnet modules registered via vnet_mod_register() is now allocated at run time in sys/kern/kern_vimage.c, instead of per vnet module structs being declared as globals. If required, vnet modules can now request the framework to provide them with allocated bzeroed memory by filling in the vmi_size field in their vmi_modinfo structures.
4) structs socket, ifnet, inpcbinfo, tcpcb and syncache_head are extended to hold a pointer to the parent vnet. options VIMAGE builds will fill in those fields as required.
5) curvnet is introduced as a new global variable in options VIMAGE builds, always pointing to the default and only struct vnet.
6) struct sysctl_oid has been extended with additional two fields to store major and minor virtualization module identifiers, oid_v_subs and oid_v_mod. SYSCTL_V_* family of macros will fill in those fields accordingly, and store the offset in the appropriate vnet container struct in oid_arg1. In sysctl handlers dealing with virtualized sysctls, the SYSCTL_RESOLVE_V_ARG1() macro will compute the address of the target variable and make it available in arg1 variable for further processing.
Unused fields in structs vnet_inet, vnet_inet6 and vnet_ipfw have been deleted.

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.
