In some situation vlan packets do not have ethernet headers. One example
is packets from tun devices. Users can specify vlan protocol in tun_pi
field instead of IP protocol. When we have a vlan device with reorder_hdr
disabled on top of the tun device, such packets from tun devices are
untagged in skb_vlan_untag() and vlan headers will be inserted back in
vlan_insert_inner_tag().
vlan_insert_inner_tag() however did not expect packets without ethernet
headers, so in such a case size argument for memmove() underflowed.
We don't need to copy headers for packets which do not have preceding
headers of vlan headers, so skip memmove() in that case.
Also don't write vlan protocol in skb->data when it does not have enough
room for it.

====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next
tree. This batch comes with more input sanitization for xtables to
address bug reports from fuzzers, preparation works to the flowtable
infrastructure and assorted updates. In no particular order, they are:
1) Make sure userspace provides a valid standard target verdict, from
Florian Westphal.
2) Sanitize error target size, also from Florian.
3) Validate that last rule in basechain matches underflow/policy since
userspace assumes this when decoding the ruleset blob that comes
from the kernel, from Florian.
4) Consolidate hook entry checks through xt_check_table_hooks(),
patch from Florian.
5) Cap ruleset allocations at 512 mbytes, 134217728 rules and reject
very large compat offset arrays, so we have a reasonable upper limit
and fuzzers don't exercise the oom-killer. Patches from Florian.
6) Several WARN_ON checks on xtables mutex helper, from Florian.
7) xt_rateest now has a hashtable per net, from Cong Wang.
8) Consolidate counter allocation in xt_counters_alloc(), from Florian.
9) Earlier xt_table_unlock() call in {ip,ip6,arp,eb}tables, patch
from Xin Long.
10) Set FLOW_OFFLOAD_DIR_* to IP_CT_DIR_* definitions, patch from
Felix Fietkau.
11) Consolidate code through flow_offload_fill_dir(), also from Felix.
12) Inline ip6_dst_mtu_forward() just like ip_dst_mtu_maybe_forward()
to remove a dependency with flowtable and ipv6.ko, from Felix.
13) Cache mtu size in flow_offload_tuple object, this is safe for
forwarding as f87c10a8aa1e describes, from Felix.
14) Rename nf_flow_table.c to nf_flow_table_core.o, to simplify too
modular infrastructure, from Felix.
15) Add rt0, rt2 and rt4 IPv6 routing extension support, patch from
Ahmed Abdelsalam.
16) Remove unused parameter in nf_conncount_count(), from Yi-Hung Wei.
17) Support for counting only to nf_conncount infrastructure, patch
from Yi-Hung Wei.
18) Add strict NFT_CT_{SRC_IP,DST_IP,SRC_IP6,DST_IP6} key datatypes
to nft_ct.
19) Use boolean as return value from ipt_ah and from IPVS too, patch
from Gustavo A. R. Silva.
20) Remove useless parameters in nfnl_acct_overquota() and
nf_conntrack_broadcast_help(), from Taehee Yoo.
21) Use ipv6_addr_is_multicast() from xt_cluster, also from Taehee Yoo.
22) Statify nf_tables_obj_lookup_byhandle, patch from Fengguang Wu.
23) Fix typo in xt_limit, from Geert Uytterhoeven.
24) Do no use VLAs in Netfilter code, again from Gustavo.
25) Use ADD_COUNTER from ebtables, from Taehee Yoo.
26) Bitshift support for CONNMARK and MARK targets, from Jack Ma.
27) Use pr_*() and add pr_fmt(), from Arushi Singhal.
28) Add synproxy support to ctnetlink.
29) ICMP type and IGMP matching support for ebtables, patches from
Matthias Schiffer.
30) Support for the revision infrastructure to ebtables, from
Bernie Harris.
31) String match support for ebtables, also from Bernie.
32) Documentation for the new flowtable infrastructure.
33) Use generic comparison functions in ebt_stp, from Joe Perches.
34) Demodularize filter chains in nftables.
35) Register conntrack hooks in case nftables NAT chain is added.
36) Merge assignments with return in a couple of spots in the
Netfilter codebase, also from Arushi.
37) Document that xtables percpu counters are stored in the same
memory area, from Ben Hutchings.
38) Revert mark_source_chains() sanity checks that break existing
rulesets, from Florian Westphal.
39) Use is_zero_ether_addr() in the ipset codebase, from Joe Perches.

Currently, driver registers it from pernet_operations::init method,
and this breaks modularity, because initialization of net namespace
and netdevice notifiers are orthogonal actions. We don't have
per-namespace netdevice notifiers; all of them are global for all
devices in all namespaces.

It's common practice to store MAC addresses for network interfaces into
nvmem devices. However the code to actually do this in the kernel lacks,
so this patch adds of_get_nvmem_mac_address() for drivers to obtain the
address from an nvmem cell provider.
This is particulary useful on devices where the ethernet interface cannot
be configured by the bootloader, for example because it's in an FPGA.

In preparation for having DSA transition entirely to PHYLINK, we need to pass a
PHY interface type to the mac_link_{up,down} callbacks because we may have to
make decisions on that (e.g: turn on/off RGMII interfaces etc.). We do not pass
an entire phylink_link_state because not all parameters (pause, duplex etc.) are
defined when the link is down, only link and interface are.
Update mvneta accordingly since it currently implements phylink_mac_ops.

NETIF_F_HW_VLAN_[CS]TAG_FILTER features require more than just a bit
flip in dev->features in order to keep the driver in a consistent state.
These features notify the driver of each added/removed vlan, but toggling
of vlan-filter does not notify the driver accordingly for each of the
existing vlans.
This patch implements a similar solution to NETIF_F_RX_UDP_TUNNEL_PORT
behavior (which notifies the driver about UDP ports in the same manner
that vids are reported).
Each toggling of the features propagates to the 8021q module, which
iterates over the vlans and call add/kill ndo accordingly.

Currently ebtables assumes that the revision number of all match
modules is 0, which is an issue when trying to use existing
xtables matches with ebtables. The solution is to modify ebtables
to allow extensions to specify a revision number, similar to
iptables. This gets passed down to the kernel, which is then able
to find the match module correctly.
To main binary backwards compatibility, the size of the ebt_entry
structures is not changed, only the size of the name field is
decreased by 1 byte to make room for the revision field.

Currently, the device geometry is stored redundantly in the nvm_id and
nvm_geo structures at a device level. Moreover, when instantiating
targets on a specific number of LUNs, these structures are replicated
and manually modified to fit the instance channel and LUN partitioning.
Instead, create a generic geometry around nvm_geo, which can be used by
(i) the underlying device to describe the geometry of the whole device,
and (ii) instances to describe their geometry independently.

Add support for the BPF_F_INGRESS flag in sk_msg redirect helper.
To do this add a scatterlist ring for receiving socks to check
before calling into regular recvmsg call path. Additionally, because
the poll wakeup logic only checked the skb recv queue we need to
add a hook in TCP stack (similar to write side) so that we have
a way to wake up polling socks when a scatterlist is redirected
to that sock.
After this all that is needed is for the redirect helper to
push the scatterlist into the psock receive queue.

This series contains Misc updates and cleanups for mlx5e rx path

From Tariq: (RX updates)
- Disable Striding RQ when PCI devices, striding RQ limits the use
of CQE compression feature, which is very critical for slow PCI
devices performance, in this change we will prefer CQE compression
over Striding RQ only on specific "slow" PCIe links.
- RX path cleanups
- Private flag to enable/disable striding RQ
From Eran: (TX fast recovery)
- TX timeout logic improvements, fast SQ recovery and TX error reporting
if a HW error occurs while transmitting on a specific SQ, the driver will
ignore such error and will wait for TX timeout to occur and reset all
the rings. Instead, the current series improves the resiliency for such
HW errors by detecting TX completions with errors, which will report them
and perform a fast recover for the specific faulty SQ even before a TX
timeout is detected.

rtnl_lock() is used everywhere, and contention is very high.
When someone wants to iterate over alive net namespaces,
he/she has no a possibility to do that without exclusive lock.
But the exclusive rtnl_lock() in such places is overkill,
and it just increases the contention. Yes, there is already
for_each_net_rcu() in kernel, but it requires rcu_read_lock(),
and this can't be sleepable. Also, sometimes it may be need
really prevent net_namespace_list growth, so for_each_net_rcu()
is not fit there.
This patch introduces new rw_semaphore, which will be used
instead of rtnl_mutex to protect net_namespace_list. It is
sleepable and allows not-exclusive iterations over net
namespaces list. It allows to stop using rtnl_lock()
in several places (what is made in next patches) and makes
less the time, we keep rtnl_mutex. Here we just add new lock,
while the explanation of we can remove rtnl_lock() there are
in next patches.
Fine grained locks generally are better, then one big lock,
so let's do that with net_namespace_list, while the situation
allows that.

This is a cosmetic patch that deals with the address filter structure's
ambiguous fields 'filter' and 'range'. The former stands to mean that the
filter's *action* should be to filter the traces to its address range if
it's set or stop tracing if it's unset. This is confusing and hard on the
eyes, so this patch replaces it with 'action' enum. The 'range' field is
completely redundant (meaning that the filter is an address range as
opposed to a single address trigger), as we can use zero size to mean the
same thing.

Userspace provides the raw EAPoL frame using NL80211_ATTR_FRAME.
Userspace should also provide the destination address and the protocol
type to use when sending the frame. This is used to implement TX of
Pre-authentication frames. If CONTROL_PORT_ETHERTYPE_NO_ENCRYPT is
specified, then the driver will be asked not to encrypt the outgoing
frame.
A new EXT_FEATURE flag is introduced so that nl80211 code can check
