rtnetlink: add new rtm tunnel api for tunnel id filtering
This patch adds new rtm tunnel msg and api for tunnel id filtering in dst_metadata devices. First dst_metadata device to use the api is vxlan driver with AF_BRIDGE family.
This and later changes add ability in vxlan driver to do tunnel id filtering (or vni filtering) on dst_metadata devices. This is similar to vlan api in the vlan filtering bridge.
this patch includes selinux nlmsg_route_perms support for RTM_*TUNNEL api from Benjamin Poirier.

include/uapi/linux/xfrm.h: Fix XFRM_MSG_MAPPING ABI breakage
Commit 2d151d39073a ("xfrm: Add possibility to set the default to block if we have no policy") broke ABI by changing the value of the XFRM_MSG_MAPPING enum item, thus also evading the build-time check in security/selinux/nlmsgtab.c:selinux_nlmsg_lookup for presence of proper security permission checks in nlmsg_xfrm_perms. Fix it by placing XFRM_MSG_SETDEFAULT/XFRM_MSG_GETDEFAULT to the end of the enum, right before __XFRM_MSG_MAX, and updating the nlmsg_xfrm_perms accordingly.

nexthop: Add netlink defines and enumerators for resilient NH groups
- RTM_NEWNEXTHOP et.al. that handle resilient groups will have a new nested attribute, NHA_RES_GROUP, whose elements are attributes NHA_RES_GROUP_*.
- RTM_NEWNEXTHOPBUCKET et.al. is a suite of new messages that will currently serve only for dumping of individual buckets of resilient next hop groups. For nexthop group buckets, these messages will carry a nested attribute NHA_RES_BUCKET, whose elements are attributes NHA_RES_BUCKET_*.
There are several reasons why a new suite of messages is created for nexthop buckets instead of overloading the information on the existing RTM_{NEW,DEL,GET}NEXTHOP messages.
First, a nexthop group can contain a large number of nexthop buckets (4k is not unheard of). This imposes limits on the amount of information that can be encoded for each nexthop bucket given a netlink message is limited to 64k bytes.
Second, while RTM_NEWNEXTHOPBUCKET is only used for notifications at this point, in the future it can be extended to provide user space with control over nexthop buckets configuration.
- The new group type is NEXTHOP_GRP_TYPE_RES. Note that nexthop code is adjusted to bounce groups with that type for now.

net: nexthop uapi
New UAPI for nexthops as standalone objects: - defines netlink ancillary header, struct nhmsg - RTM commands for nexthop objects, RTM_*NEXTHOP, - RTNLGRP for nexthop notifications, RTNLGRP_NEXTHOP, - Attributes for creating nexthops, NHA_* - Attribute for route specs to specify a nexthop by id, RTA_NH_ID.
The nexthop attributes and semantics follow the route and RTA ones for device, gateway and lwt encap. Unique to nexthop objects are a blackhole and a group which contains references to other nexthop objects. With the exception of blackhole and group, nexthop objects MUST contain a device. Gateway and encap are optional. Nexthop groups can only reference other pre-existing nexthops by id. If the NHA_ID attribute is present that id is used for the nexthop. If not specified, one is auto assigned.
Dump requests can include attributes: - NHA_GROUPS to return only nexthop groups, - NHA_MASTER to limit dumps to nexthops with devices enslaved to the given master (e.g., VRF) - NHA_OIF to limit dumps to nexthops using given device
nlmsg_route_perms in selinux code is updated for the new RTM comands.

selinux: add support for RTM_NEWCHAIN, RTM_DELCHAIN, and RTM_GETCHAIN
Commit 32a4f5ecd738 ("net: sched: introduce chain object to uapi") added new RTM_* definitions without properly updating SELinux, this patch adds the necessary SELinux support.
While there was a BUILD_BUG_ON() in the SELinux code to protect from exactly this case, it was bypassed in the broken commit. In order to hopefully prevent this from happening in the future, add additional comments which provide some instructions on how to resolve the BUILD_BUG_ON() failures.

rtnetlink: add new RTM_GETSTATS message to dump link stats
This patch adds a new RTM_GETSTATS message to query link stats via netlink from the kernel. RTM_NEWLINK also dumps stats today, but RTM_NEWLINK returns a lot more than just stats and is expensive in some cases when frequent polling for stats from userspace is a common operation.
RTM_GETSTATS is an attempt to provide a light weight netlink message to explicity query only link stats from the kernel on an interface. The idea is to also keep it extensible so that new kinds of stats can be added to it in the future.
This patch adds the following attribute for NETDEV stats: struct nla_policy ifla_stats_policy[IFLA_STATS_MAX + 1] = { [IFLA_STATS_LINK_64] = { .len = sizeof(struct rtnl_link_stats64) }, };
Like any other rtnetlink message, RTM_GETSTATS can be used to get stats of a single interface or all interfaces with NLM_F_DUMP.
Future possible new types of stat attributes: link af stats: - IFLA_STATS_LINK_IPV6 (nested. for ipv6 stats) - IFLA_STATS_LINK_MPLS (nested. for mpls/mdev stats) extended stats: - IFLA_STATS_LINK_EXTENDED (nested. extended software netdev stats like bridge, vlan, vxlan etc) - IFLA_STATS_LINK_HW_EXTENDED (nested. extended hardware stats which are available via ethtool today)
This patch also declares a filter mask for all stat attributes. User has to provide a mask of stats attributes to query. filter mask can be specified in the new hdr 'struct if_stats_msg' for stats messages. Other important field in the header is the ifindex.
This api can also include attributes for global stats (eg tcp) in the future. When global stats are included in a stats msg, the ifindex in the header must be zero. A single stats message cannot contain both global and netdev specific stats. To easily distinguish them, netdev specific stat attributes name are prefixed with IFLA_STATS_LINK_
Without any attributes in the filter_mask, no stats will be returned.
This patch has been tested with mofified iproute2 ifstat.
