Add utility functions to convert a 32 bits key into a 64 bits tunnel and
vice versa.
These functions will be used instead of cloning code in GRE and VXLAN,
and in tc act_iptunnel which will be introduced in a following patch in
this patchset.

vxlan_dev_configure outputs error messages before returning, no need to
print again the same mesages in vxlan_newlink. Also, vxlan_dev_configure may
return a particular error code for a different reason than vxlan_newlink
thinks.
Move the remaining error messages into vxlan_dev_configure and let
vxlan_newlink just pass on the error code.

Currently, kernel accepts configurations such as:
ip l a type vxlan dstport 4789 id 1 group 239.192.0.1
ip l a type vxlan dstport 4789 id 1 group ff0e::110
However, neither of those really works. In the IPv4 case, the interface
cannot be brought up ("RTNETLINK answers: No such device"). This is because
multicast join will be rejected without the interface being specified.
In the IPv6 case, multicast wil be joined on the first interface found. This
is not what the user wants as it depends on random factors (order of
interfaces).
Note that it's possible to add a local address but it doesn't solve
anything. For IPv4, it's not considered in the multicast join (thus the same
error as above is returned on ifup). This could be added but it wouldn't
help for IPv6 anyway. For IPv6, we do need the interface.
Just reject a configuration that sets multicast address and does not provide
an interface. Nobody can depend on the previous behavior as it never worked.

fdb dumps spanning multiple skb's currently restart from the first
interface again for every skb. This results in unnecessary
iterations on the already visited interfaces and their fdb
entries. In large scale setups, we have seen this to slow
down fdb dumps considerably. On a system with 30k macs we
see fdb dumps spanning across more than 300 skbs.
To fix the problem, this patch replaces the existing single fdb
marker with three markers: netdev hash entries, netdevs and fdb
index to continue where we left off instead of restarting from the
first netdev. This is consistent with link dumps.
In the process of fixing the performance issue, this patch also
re-implements fix done by
commit 472681d57a5d ("net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump")
(with an internal fix from Wilson Kok) in the following ways:
- change ndo_fdb_dump handlers to return error code instead
of the last fdb index
- use cb->args strictly for dump frag markers and not error codes.
This is consistent with other dump functions.
Below results were taken on a system with 1000 netdevs
and 35085 fdb entries:
before patch:
$time bridge fdb show | wc -l
15065
real 1m11.791s
user 0m0.070s
sys 1m8.395s
(existing code does not return all macs)

The fact is VXLAN with Generic Protocol Extensions cannot be supported by
the same hardware parsers that support VXLAN. The protocol extensions
allow for things like a Next Protocol field which in turn allows for things
other than Ethernet to be passed over the tunnel. Most existing parsers
will not know how to interpret this.
To resolve this I am giving VXLAN-GPE its own UDP encapsulation offload
type. This way hardware that does support GPE can simply add this type to
the switch statement for VXLAN, and if they don't support it then this will
fix any issues where headers might be interpreted incorrectly.

This patch merges the notifiers for VXLAN and GENEVE into a single UDP
tunnel notifier. The idea is that we will want to only have to make one
notifier call to receive the list of ports for VXLAN and GENEVE tunnels
that need to be offloaded.
In addition we add a new set of ndo functions named ndo_udp_tunnel_add and
ndo_udp_tunnel_del that are meant to allow us to track the tunnel meta-data
such as port and address family as tunnels are added and removed. The
tunnel meta-data is now transported in a structure named udp_tunnel_info
which for now carries the type, address family, and port number. In the
future this could be updated so that we can include a tuple of values
including things such as the destination IP address and other fields.
I also ended up going with a naming scheme that consisted of using the
prefix udp_tunnel on function names. I applied this to the notifier and
ndo ops as well so that it hopefully points to the fact that these are
primarily used in the udp_tunnel functions.

The function vxlan_dev_create() (only used by ovs) never calls
rtnl_configure_link(). The consequence is that dev->rtnl_link_state is
never set to RTNL_LINK_INITIALIZED.
During the deletion phase, the function rollback_registered_many() sends
a RTM_DELLINK only if dev->rtnl_link_state is set to RTNL_LINK_INITIALIZED.
Note that the function vxlan_dev_create() is moved after the rtnl stuff so
that vxlan_dellink() can be called in this function.

In case we find a socket with encapsulation enabled we should call
the encap_recv function even if just a udp header without payload is
available. The callbacks are responsible for correctly verifying and
dropping the packets.
Also, in case the header validation fails for geneve and vxlan we
shouldn't put the skb back into the socket queue, no one will pick
them up there. Instead we can simply discard them in the respective
encap_recv functions.

UDP tunnel segmentation code relies on the inner offsets being set for
an UDP tunnel GSO packet, but the inner *_complete() functions will
set the inner offsets only if 'encapsulation' is set before calling
them. Currently, udp_gro_complete() sets 'encapsulation' only after
the inner *_complete() functions are done. This causes the inner
offsets having invalid values after udp_gro_complete() returns, which
in turn will make it impossible to properly segment the packet in case
it needs to be forwarded, which would be visible to the user either as
invalid packets being sent or as packet loss.
This patch fixes this by setting skb's 'encapsulation' in
udp_gro_complete() before calling into the inner complete functions,
and by making each possible UDP tunnel gro_complete() callback set the
inner_mac_header to the beginning of the tunnel payload.

Commit 0c867c9bf84c ("vxlan: move Ethernet initialization to a separate
function") changed initialization order and as an unintended result, when the
user specifies additional link parameters (such as IFLA_ADDRESS) while
creating vxlan interface, those are overwritten by vxlan_ether_setup later.
It's necessary to call ether_setup from withing the ->setup callback. That
way, the correct parameters are set by rtnl_create_link later. This is done
also for VXLAN-GPE, as we don't know the interface type yet at that point,
and changed to the correct interface type later.

Currently all drivers depend and autoload the vxlan module because how
vxlan_get_rx_port is linked into them. Remove this dependency:
By using a new event type in the netdevice notifier call chain we proxy
the request from the drivers to flush and resetup the vxlan ports not
directly via function call but by the already existing netdevice
notifier call chain.
I added a separate new event type, NETDEV_OFFLOAD_PUSH_VXLAN, to do so.
We don't need to save those ids, as the event type field is an unsigned
long and using specialized event types for this purpose seemed to be a
more elegant way. This also comes in beneficial if in future we want to
add offloading knobs for vxlan.

This patch updates the IP tunnel core function iptunnel_handle_offloads so
that we return an int and do not free the skb inside the function. This
actually allows us to clean up several paths in several tunnels so that we
can free the skb at one point in the path without having to have a
secondary path if we are supporting tunnel offloads.
In addition it should resolve some double-free issues I have found in the
tunnels paths as I believe it is possible for us to end up triggering such
an event in the case of fou or gue.

Due to the fact that the udp socket is destructed asynchronously in a
work queue, we have some nondeterministic behavior during shutdown of
vxlan tunnels and creating new ones. Fix this by keeping the destruction
process synchronous in regards to the user space process so IFF_UP can
be reliably set.
udp_tunnel_sock_release destroys vs->sock->sk if reference counter
indicates so. We expect to have the same lifetime of vxlan_sock and
vxlan_sock->sock->sk even in fast paths with only rcu locks held. So
only destruct the whole socket after we can be sure it cannot be found
by searching vxlan_net->sock_list.

Implement VXLAN-GPE. Only COLLECT_METADATA is supported for now (it is
possible to support static configuration, too, if there is demand for it).
The GPE header parsing has to be moved before iptunnel_pull_header, as we
need to know the protocol.
v2: Removed what was called "L2 mode" in v1 of the patchset. Only "L3 mode"
(now called "raw mode") is added by this patch. This mode does not allow
Ethernet header to be encapsulated in VXLAN-GPE when using ip route to
specify the encapsulation, IP header is encapsulated instead. The patch
does support Ethernet to be encapsulated, though, using ETH_P_TEB in
skb->protocol. This will be utilized by other COLLECT_METADATA users
(openvswitch in particular).
If there is ever demand for Ethernet encapsulation with VXLAN-GPE using
ip route, it's easy to add a new flag switching the interface to
"Ethernet mode" (called "L2 mode" in v1 of this patchset). For now,
leave this out, it seems we don't need it.
Disallowed more flag combinations, especially RCO with GPE.
Added comment explaining that GBP and GPE cannot be set together.

For example, for policy routing, fib6_rule_match() uses ip6_tclass()
that is applied on the flowlabel member for matching on tclass. Similar
fix is needed for geneve, where flowi6_tos is set as well. Installing
a v6 blackhole rule that f.e. matches on tos is now working with vxlan.

This patch updates the GRO handlers for GRE, VXLAN, GENEVE, and FOU so that
we do not clear the flush bit until after we have called the next level GRO
handler. Previously this was being cleared before parsing through the list
of frames, however this resulted in several paths where either the bit
needed to be reset but wasn't as in the case of FOU, or cases where it was
being set as in GENEVE. By just deferring the clearing of the bit until
after the next level protocol has been parsed we can avoid any unnecessary
bit twiddling and avoid bugs.

The assumptions from commit 0c1d70af924b ("net: use dst_cache for vxlan
device"), 468dfffcd762 ("geneve: add dst caching support") and 3c1cb4d2604c
("net/ipv4: add dst cache support for gre lwtunnels") on dst_cache usage
when ip_tunnel_info is used is unfortunately not always valid as assumed.
While it seems correct for ip_tunnel_info front-ends such as OVS, eBPF
however can fill in ip_tunnel_info for consumers like vxlan, geneve or gre
with different remote dsts, tos, etc, therefore they cannot be assumed as
packet independent.
Right now vxlan, geneve, gre would cache the dst for eBPF and every packet
would reuse the same entry that was first created on the initial route
lookup. eBPF doesn't store/cache the ip_tunnel_info, so each skb may have
a different one.
Fix it by adding a flag that checks the ip_tunnel_info. Also the !tos test
in vxlan needs to be handeled differently in this context as it is currently
inferred from ip_tunnel_info as well if present. ip_tunnel_dst_cache_usable()
helper is added for the three tunnel cases, which checks if we can use dst
cache.

When signalling to metadata consumers that the metadata_dst entry

the dst's vxlan_metadata information is populated, but options_len

Geneve uses ip_tunnel_info_opts_set() helper in receive path, which
sets options_len internally, vxlan however uses ip_tunnel_info_opts(),
