'alloc_etherdev_mqs()' expects first 'tx', then 'rx'. The semantic here
looks reversed.
Reorder the arguments passed to 'alloc_etherdev_mqs()' in order to keep
the correct semantic.
In fact, this is a no-op because both XGENE_NUM_[RT]X_RING are 8.

Defaults for min_mtu and max_mtu are set by ether_setup(), which is
called from devm_alloc_etherdev(). Let rtl_jumbo_max() only return
a positive value if actually jumbo packets are supported. This also
allows to remove constant Jumbo_1K which is a little misleading anyway.

DSA sets up a switch tree little by little. Every switch of the N
members of the tree calls dsa_register_switch, and (N - 1) will just
touch the dst->ports list with their ports and quickly exit. Only the
last switch that calls dsa_register_switch will find all DSA links
complete in dsa_tree_setup_routing_table, and not return zero as a
result but instead go ahead and set up the entire DSA switch tree
(practically on behalf of the other switches too).
The trouble is that the (N - 1) switches don't clean up after themselves
after they get an error such as EPROBE_DEFER. Their footprint left in
dst->ports by dsa_switch_touch_ports is still there. And switch N, the
one responsible with actually setting up the tree, is going to work with
those stale dp, dp->ds and dp->ds->dev pointers. In particular ds and
ds->dev might get freed by the device driver.
Be there a 2-switch tree and the following calling order:
- Switch 1 calls dsa_register_switch
- Calls dsa_switch_touch_ports, populates dst->ports
- Calls dsa_port_parse_cpu, gets -EPROBE_DEFER, exits.
- Switch 2 calls dsa_register_switch
- Calls dsa_switch_touch_ports, populates dst->ports
- Probe doesn't get deferred, so it goes ahead.
- Calls dsa_tree_setup_routing_table, which returns "complete == true"
due to Switch 1 having called dsa_switch_touch_ports before.
- Because the DSA links are complete, it calls dsa_tree_setup_switches
now.
- dsa_tree_setup_switches iterates through dst->ports, initializing
the Switch 1 ds structure (invalid) and the Switch 2 ds structure
(valid).
- Undefined behavior (use after free, sometimes NULL pointers, etc).

The solution is to recognize that the functions that call
dsa_switch_touch_ports (dsa_switch_parse_of, dsa_switch_parse) have side
effects, and therefore one should clean up their side effects on error
path. The cleanup of dst->ports was taken from dsa_switch_remove and
moved into a dedicated dsa_switch_release_ports function, which should
really be per-switch (free only the members of dst->ports that are also
members of ds, instead of all switch ports).

net: allow per-net notifier to follow netdev into namespace
Currently we have per-net notifier, which allows to get only
notifications relevant to particular network namespace. That is enough
for drivers that have netdevs local in a particular namespace (cannot
move elsewhere).
However if netdev can change namespace, per-net notifier cannot be used.
Introduce dev_net variant that is basically per-net notifier with an
extension that re-registers the per-net notifier upon netdev namespace
change. Basically the per-net notifier follows the netdev into

====================
Support fraglist GRO/GSO
This patchset adds support to do GRO/GSO by chaining packets
of the same flow at the SKB frag_list pointer. This avoids
the overhead to merge payloads into one big packet, and
on the other end, if GSO is needed it avoids the overhead
of splitting the big packet back to the native form.
Patch 1 adds netdev feature flags to enable fraglist GRO,
this implements one of the configuration options discussed
at netconf 2019.
Patch 2 adds a netdev software feature set that defaults to off
and assigns the new fraglist GRO feature flag to it.
Patch 3 adds the core infrastructure to do fraglist GRO/GSO.
Patch 4 enables UDP to use fraglist GRO/GSO if configured.
I have only meaningful forwarding performance measurements.
I did some tests for the local receive path with netperf and iperf,
but in this case the sender that generates the packets is the
bottleneck. So the benchmarks are not that meaningful for the
receive path.
Paolo Abeni did some benchmarks of the local receive path for the
RFC v2 version of this pachset, results can be found here:
https://www.spinics.net/lists/netdev/msg551158.html

- Split patchset to enable UDP GRO by default before adding
fraglist GRO support.
- Mark fraglist GRO packets as CHECKSUM_NONE.
- Take a refcount on the first segment skb when doing fraglist
segmentation. With this we can use the same error handling
path as with standard segmentation.
Changes from RFC v2:
- Add a netdev feature flag to configure listifyed GRO.
- Fix UDP GRO enabling for IPv6.
- Fix a rcu_read_lock() imbalance.
- Fix error path in skb_segment_list().
Changes from RFC v3:
- Rename NETIF_F_GRO_LIST to NETIF_F_GRO_FRAGLIST and add

- Move introduction of SKB_GSO_FRAGLIST to patch 2.
- Use udpv6_encap_needed_key instead of udp_encap_needed_key in IPv6.
- Move some missplaced code from patch 5 to patch 1 where it belongs to.
Changes from RFC v4:
- Drop the 'UDP: enable GRO by default' patch for now. Standard UDP GRO
is not changed with this patchset.
- Rebase to net-next current.
Changes fom v1 (December 18th):
- Do a full __copy_skb_header instead of tryng to find the really
needed subset header fields. Thisa can be done later.
- Mark all fraglist GRO packets with CHECKSUM_UNNECESSARY.
- Rebase to net-next current.

- Do the CHECKSUM_UNNECESSARY setting from IPv4 for IPv6 too.

This patch extends UDP GRO to support fraglist GRO/GSO
by using the previously introduced infrastructure.
If the feature is enabled, all UDP packets are going to
fraglist GRO (local input and forward).
After validating the csum, we mark ip_summed as
CHECKSUM_UNNECESSARY for fraglist GRO packets to
make sure that the csum is not touched.

The subpacket scanning loop in rxrpc_receive_data() references the
subpacket count in the private data part of the sk_buff in the loop
termination condition. However, when the final subpacket is pasted into
the ring buffer, the function is no longer has a ref on the sk_buff and
should not be looking at sp->* any more. This point is actually marked in
the code when skb is cleared (but sp is not - which is an error).
Fix this by caching sp->nr_subpackets in a local variable and using that
instead.
Also clear 'sp' to catch accesses after that point.
This can show up as an oops in rxrpc_get_skb() if sp->nr_subpackets gets
trashed by the sk_buff getting freed and reused in the meantime.

The current implementations of ops->bind_class() are merely
searching for classid and updating class in the struct tcf_result,
without invoking either of cl_ops->bind_tcf() or
cl_ops->unbind_tcf(). This breaks the design of them as qdisc's
like cbq use them to count filters too. This is why syzbot triggered
the warning in cbq_destroy_class().
In order to fix this, we have to call cl_ops->bind_tcf() and
cl_ops->unbind_tcf() like the filter binding path. This patch does
so by refactoring out two helper functions __tcf_bind_filter()
and __tcf_unbind_filter(), which are lockless and accept a Qdisc
pointer, then teaching each implementation to call them correctly.
Note, we merely pass the Qdisc pointer as an opaque pointer to
each filter, they only need to pass it down to the helper
functions without understanding it at all.

Netfilter updates for net-next
This batch contains Netfilter updates for net-next:
1) Add nft_setelem_parse_key() helper function.
2) Add NFTA_SET_ELEM_KEY_END to specify a range with one single element.
3) Add NFTA_SET_DESC_CONCAT to describe the set element concatenation,
from Stefano Brivio.
4) Add bitmap_cut() to copy n-bits from source to destination,
from Stefano Brivio.
5) Add set to match on arbitrary concatenations, from Stefano Brivio.
6) Add selftest for this new set type. An extract of Stefano's
description follows:
"Existing nftables set implementations allow matching entries with
interval expressions (rbtree), e.g. 192.0.2.1-192.0.2.4, entries
specifying field concatenation (hash, rhash), e.g. 192.0.2.1:22,
but not both.
In other words, none of the set types allows matching on range
expressions for more than one packet field at a time, such as ipset
does with types bitmap:ip,mac, and, to a more limited extent
(netmasks, not arbitrary ranges), with types hash:net,net,
hash:net,port, hash:ip,port,net, and hash:net,port,net.
As a pure hash-based approach is unsuitable for matching on ranges,
and "proxying" the existing red-black tree type looks impractical as
elements would need to be shared and managed across all employed
trees, this new set implementation intends to fill the functionality
gap by employing a relatively novel approach.
The fundamental idea, illustrated in deeper detail in patch 5/9, is to
use lookup tables classifying a small number of grouped bits from each
field, and map the lookup results in a way that yields a verdict for
the full set of specified fields.
The grouping bit aspect is loosely inspired by the Grouper algorithm,
by Jay Ligatti, Josh Kuhn, and Chris Gage (see patch 5/9 for the full
reference).
A reference, stand-alone implementation of the algorithm itself is
available at:
https://pipapo.lameexcu.se
Some notes about possible future optimisations are also mentioned
there. This algorithm reduces the matching problem to, essentially,
a repetitive sequence of simple bitwise operations, and is
particularly suitable to be optimised by leveraging SIMD instruction
sets."

This test covers functionality and stability of the newly added
nftables set implementation supporting concatenation of ranged
fields.
For some selected set expression types, test:
- correctness, by checking that packets match or don't
- concurrency, by attempting races between insertion, deletion, lookup
- timeout feature, checking that packets don't match expired entries
and (roughly) estimate matching rates, comparing to baselines for
simple drop on netdev ingress hook and for hash and rbtrees sets.
In order to send packets, this needs one of sendip, netcat or bash.
To flood with traffic, iperf3, iperf and netperf are supported. For
performance measurements, this relies on the sample pktgen script
pktgen_bench_xmit_mode_netif_receive.sh.
If none of the tools suitable for a given test are available, specific
tests will be skipped.

This new set type allows for intervals in concatenated fields,
which are expressed in the usual way, that is, simple byte
concatenation with padding to 32 bits for single fields, and
given as ranges by specifying start and end elements containing,
each, the full concatenation of start and end values for the
single fields.
Ranges are expanded to composing netmasks, for each field: these
are inserted as rules in per-field lookup tables. Bits to be
classified are divided in 4-bit groups, and for each group, the
lookup table contains 4^2 buckets, representing all the possible
values of a bit group. This approach was inspired by the Grouper
algorithm:
http://www.cse.usf.edu/~ligatti/projects/grouper/
Matching is performed by a sequence of AND operations between
bucket values, with buckets selected according to the value of
packet bits, for each group. The result of this sequence tells
us which rules matched for a given field.
In order to concatenate several ranged fields, per-field rules
are mapped using mapping arrays, one per field, that specify
which rules should be considered while matching the next field.
The mapping array for the last field contains a reference to
the element originally inserted.
The notes in nft_set_pipapo.c cover the algorithm in deeper
detail.
A pure hash-based approach is of no use here, as ranges need
to be classified. An implementation based on "proxying" the
existing red-black tree set type, creating a tree for each
field, was considered, but deemed impractical due to the fact
that elements would need to be shared between trees, at least
as long as we want to keep UAPI changes to a minimum.
A stand-alone implementation of this algorithm is available at:
https://pipapo.lameexcu.se
together with notes about possible future optimisations
(in pipapo.c).
This algorithm was designed with data locality in mind, and can
be highly optimised for SIMD instruction sets, as the bulk of
the matching work is done with repetitive, simple bitwise
operations.

- rework interface for field length specification,

description
- remove scratch area to store closing element of ranges,
as elements now come with an actual attribute to specify
the upper range limit (Pablo Neira Ayuso)
- also remove pointer to 'start' element from mapping table,
closing key is now accessible via extension data
- use bytes right away instead of bits for field lengths,
this way we can also double the inner loop of the lookup
function to take care of upper and lower bits in a single
iteration (minor performance improvement)
- make it clearer that set operations are actually atomic
API-wise, but we can't e.g. implement flush() as one-shot
action
- fix type for 'dup' in nft_pipapo_insert(), check for
duplicates only in the next generation, and in general take
care of differentiating generation mask cases depending on
the operation (Pablo Neira Ayuso)
- report C implementation matching rate in commit message, so
that AVX2 implementation can be compared (Pablo Neira Ayuso)
v2:
- protect access to scratch maps in nft_pipapo_lookup() with
local_bh_disable/enable() (Florian Westphal)
- drop rcu_read_lock/unlock() from nft_pipapo_lookup(), it's
already implied (Florian Westphal)
- explain why partial allocation failures don't need handling
in pipapo_realloc_scratch(), rename 'm' to clone and update
related kerneldoc to make it clear we're not operating on
the live copy (Florian Westphal)
- add expicit check for priv->start_elem in
nft_pipapo_insert() to avoid ending up in nft_pipapo_walk()
with a NULL start element, and also zero it out in every
operation that might make it invalid, so that insertion
doesn't proceed with an invalid element (Florian Westphal)

Introduce a new nested netlink attribute, NFTA_SET_DESC_CONCAT, used
to specify the length of each field in a set concatenation.
This allows set implementations to support concatenation of multiple
ranged items, as they can divide the input key into matching data for
every single field. Such set implementations would be selected as
they specify support for NFT_SET_INTERVAL and allow desc->field_count
to be greater than one. Explicitly disallow this for nft_set_rbtree.
In order to specify the interval for a set entry, userspace would
include in NFTA_SET_DESC_CONCAT attributes field lengths, and pass
range endpoints as two separate keys, represented by attributes
NFTA_SET_ELEM_KEY and NFTA_SET_ELEM_KEY_END.
While at it, export the number of 32-bit registers available for
packet matching, as nftables will need this to know the maximum
number of field lengths that can be specified.
For example, "packets with an IPv4 address between 192.0.2.0 and
192.0.2.42, with destination port between 22 and 25", can be
expressed as two concatenated elements:
NFTA_SET_ELEM_KEY: 192.0.2.0 . 22
NFTA_SET_ELEM_KEY_END: 192.0.2.42 . 25
and NFTA_SET_DESC_CONCAT attribute would contain:
NFTA_LIST_ELEM
NFTA_SET_FIELD_LEN: 4
NFTA_LIST_ELEM
NFTA_SET_FIELD_LEN: 2

When data is received on the READ channel, the matching logic for cmds
that are waiting for a reply is currently hard-coded into the channel's
main IO callback.
Move this into a per-cmd callback, so that we can apply custom matching
logic for each individual cmd.
This also allows us to remove the coarse-grained check for unexpected
non-IPA replies, since they will no longer match against _all_ pending
cmds.
Note that IDX cmds use _no_ matcher, since their reply is synchronously
received as part of the cmd's IO.

Pull ARM SoC fixes from Olof Johansson:
"A couple of fixes have come in that would be good to include in this
release:
- A fix for amount of memory on Beaglebone Black. Surfaced now since
GRUB2 doesn't update memory size in the booted kernel.
- A fix to make SPI interfaces work on am43x-epos-evm.
- Small Kconfig fix for OPTEE (adds a depend on MMU) to avoid build
failures"
