ICMP flow improvements
This series improves the flow inspector handling of ICMP packets:
The first two patches just add some comments in the code which would have saved
me a few minutes of time, and refactor a piece of code.
The third one adds to the flow inspector the capability to extract the
Identifier field, if present, so echo requests and replies are classified
as part of the same flow.
The fourth patch uses the function introduced earlier to the bonding driver,
so echo replies can be balanced across bonding slaves.
v1 -> v2:
- remove unused struct members
- add an helper to check for the Id field
- use a local flow_dissector_key in the bonding to avoid
changing behaviour of the flow dissector
====================

The bonding uses the L4 ports to balance flows between slaves. As the ICMP
protocol has no ports, those packets are sent all to the same device:
# tcpdump -qltnni veth0 ip |sed 's/^/0: /' &
# tcpdump -qltnni veth1 ip |sed 's/^/1: /' &
# ping -qc1 192.168.0.2
1: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 315, seq 1, length 64
1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 315, seq 1, length 64
# ping -qc1 192.168.0.2
1: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 316, seq 1, length 64
1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 316, seq 1, length 64
# ping -qc1 192.168.0.2
1: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 317, seq 1, length 64
1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 317, seq 1, length 64
But some ICMP packets have an Identifier field which is
used to match packets within sessions, let's use this value in the hash
function to balance these packets between bond slaves:
# ping -qc1 192.168.0.2
0: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 303, seq 1, length 64
0: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 303, seq 1, length 64
# ping -qc1 192.168.0.2
1: IP 192.168.0.1 > 192.168.0.2: ICMP echo request, id 304, seq 1, length 64
1: IP 192.168.0.2 > 192.168.0.1: ICMP echo reply, id 304, seq 1, length 64
Aso, let's use a flow_dissector_key which defines FLOW_DISSECTOR_KEY_ICMP,
so we can balance pings encapsulated in a tunnel when using mode encap3+4:
# ping -q 192.168.1.2 -c1
0: IP 192.168.0.1 > 192.168.0.2: GREv0, length 102: IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 585, seq 1, length 64
0: IP 192.168.0.2 > 192.168.0.1: GREv0, length 102: IP 192.168.1.2 > 192.168.1.1: ICMP echo reply, id 585, seq 1, length 64
# ping -q 192.168.1.2 -c1
1: IP 192.168.0.1 > 192.168.0.2: GREv0, length 102: IP 192.168.1.1 > 192.168.1.2: ICMP echo request, id 586, seq 1, length 64

We introduce a feature that works like a combination of TCP_NAGLE and
TCP_CORK, but without some of the weaknesses of those. In particular,
we will not observe long delivery delays because of delayed acks, since
the algorithm itself decides if and when acks are to be sent from the
receiving peer.
- The nagle property as such is determined by manipulating a new
'maxnagle' field in struct tipc_sock. If certain conditions are met,
'maxnagle' will define max size of the messages which can be bundled.
If it is set to zero no messages are ever bundled, implying that the
nagle property is disabled.
- A socket with the nagle property enabled enters nagle mode when more
than 4 messages have been sent out without receiving any data message
from the peer.
- A socket leaves nagle mode whenever it receives a data message from
the peer.
In nagle mode, messages smaller than 'maxnagle' are accumulated in the
socket write queue. The last buffer in the queue is marked with a new
'ack_required' bit, which forces the receiving peer to send a CONN_ACK
message back to the sender upon reception.
The accumulated contents of the write queue is transmitted when one of
the following events or conditions occur.
- A CONN_ACK message is received from the peer.
- A data message is received from the peer.
- A SOCK_WAKEUP pseudo message is received from the link level.
- The write queue contains more than 64 1k blocks of data.
- The connection is being shut down.
- There is no CONN_ACK message to expect. I.e., there is currently
no outstanding message where the 'ack_required' bit was set. As a
consequence, the first message added after we enter nagle mode
is always sent directly with this bit set.
This new feature gives a 50-100% improvement of throughput for small
(i.e., less than MTU size) messages, while it might add up to one RTT
to latency time when the socket is in nagle mode.

nfc: pn533: add uart phy driver
The purpose of this patch series is to add a uart phy driver to the
pn533 nfc driver.
It first changes the dt strings and docs. The dt compatible strings
need to change, because I would add "pn532-uart" to the already
existing "pn533-i2c" one. These two are now unified into just
"pn532". Then the neccessary changes to the pn533 core driver are
made. Then the uart phy is added.
As the pn532 chip supports a autopoll, I wanted to use this instead
of the software poll loop in the pn533 core driver. It is added and
activated by the last to patches.
The way to add the autopoll later in seperate patches is chosen, to
show, that the uart phy driver can also work with the software poll
loop, if someone needs that for some reason.
In v11 of this patchseries I address a byte ordering issue reported
by kbuild test robot in patch 5/7.

There is a problem in the initialisation and setup of the pn533: It
registers with nfc too early. It could happen, that it finished
registering with nfc and someone starts using it. But setup of the pn533
is not yet finished. Bad or at least unintended things could happen.
So I split out nfc registering (and unregistering) to seperate functions
that have to be called late in probe then.
i2c requires a bit more love: i2c requests an irq in it's probe
function. 'Commit 32ecc75ded ("NFC: pn533: change order operations in
dev registation")' shows, this can not happen too early. An irq can be
served before structs are fully initialized. The way chosen to prevent
this is to request the irq after nfc_alloc_device initialized the
structs, but before nfc_register_device. So there is now this
pn532_i2c_nfc_alloc function.

The idea is to inform the phy driver when the nfc chip is really going

not in use before dev_up and after dev_down.

net: bridge: convert fdbs to use bitops
We'd like to have a well-defined behaviour when changing fdb flags. The
problem is that we've added new fields which are changed from all
contexts without any locking. We are aware of the bit test/change races
and these are fine (we can remove them later), but it is considered
undefined behaviour to change bitfields from multiple threads and also
on some architectures that can result in unexpected results,
specifically when all fields between the changed ones are also
bitfields. The conversion to bitops shows the intent clearly and
makes them use functions with well-defined behaviour in such cases.
There is no overhead for the fast-path, the bit changing functions are
used only in special cases when learning and in the slow path.
In addition this conversion allows us to simplify fdb flag handling and
avoid bugs for future bits (e.g. a forgetting to clear the new bit when
allocating a new fdb). All bridge selftests passed, also tried all of the
converted bits manually in a VM.

Currently, TIPC transports intra-node user data messages directly
socket to socket, hence shortcutting all the lower layers of the
communication stack. This gives TIPC very good intra node performance,
both regarding throughput and latency.
We now introduce a similar mechanism for TIPC data traffic across
network namespaces located in the same kernel. On the send path, the
call chain is as always accompanied by the sending node's network name
space pointer. However, once we have reliably established that the
receiving node is represented by a namespace on the same host, we just
replace the namespace pointer with the receiving node/namespace's
ditto, and follow the regular socket receive patch though the receiving
node. This technique gives us a throughput similar to the node internal
throughput, several times larger than if we let the traffic go though
the full network stacks. As a comparison, max throughput for 64k
messages is four times larger than TCP throughput for the same type of
traffic.
To meet any security concerns, the following should be noted.
- All nodes joining a cluster are supposed to have been be certified
and authenticated by mechanisms outside TIPC. This is no different for
nodes/namespaces on the same host; they have to auto discover each
other using the attached interfaces, and establish links which are
supervised via the regular link monitoring mechanism. Hence, a kernel
local node has no other way to join a cluster than any other node, and
have to obey to policies set in the IP or device layers of the stack.
- Only when a sender has established with 100% certainty that the peer
node is located in a kernel local namespace does it choose to let user
data messages, and only those, take the crossover path to the receiving
node/namespace.
- If the receiving node/namespace is removed, its namespace pointer
is invalidated at all peer nodes, and their neighbor link monitoring
will eventually note that this node is gone.
- To ensure the "100% certainty" criteria, and prevent any possible
spoofing, received discovery messages must contain a proof that the
sender knows a common secret. We use the hash mix of the sending
node/namespace for this purpose, since it can be accessed directly by
all other namespaces in the kernel. Upon reception of a discovery
message, the receiver checks this proof against all the local
namespaces'hash_mix:es. If it finds a match, that, along with a
matching node id and cluster id, this is deemed sufficient proof that
the peer node in question is in a local namespace, and a wormhole can
be opened.
- We should also consider that TIPC is intended to be a cluster local
IPC mechanism (just like e.g. UNIX sockets) rather than a network
protocol, and hence we think it can justified to allow it to shortcut the
lower protocol layers.
Regarding traceability, we should notice that since commit 6c9081a391
("tipc: add loopback device tracking") it is possible to follow the node
internal packet flow by just activating tcpdump on the loopback
interface. This will be true even for this mechanism; by activating
tcpdump on the involved nodes' loopback interfaces their inter-name
space messaging can easily be tracked.
v2:
- update 'net' pointer when node left/rejoined
v3:
- grab read/write lock when using node ref obj
v4:
- clone traffics between netns to loopback

40GbE Intel Wired LAN Driver Updates 2019-10-25
This series contains updates to i40e only. Several are fixes that could
go to 'net', but were intended for 'net-next'.
Sylwia changes how the driver function to read the NVM module data, so
that it is able to read the LLDP agent configuration to allow for
persistent LLDP.
Jaroslaw resolves an issue where the incorrect FEC settings were being
displayed in ethtool, by setting the proper FEC bits.
Piotr moves the hardware flags detection into a separate function, so
that the specific flags can be set based on the MAC and NVM. Also
extends the PHY access function to include a command flag to let the
firmware know it should not change the page while accessing a OSFP module.
Updates the driver to display the driver and firmware version when in
recovery mode.
Aleksandr refactored the VF MAC filters accounting since an untrusted
VF was able to delete but not add a MAC filter, so refactor the code to
have more consistency and improved logging.
Nicholas updates the driver to use a default interval of 50 usecs,
instead of the current 100 usecs which was causing some regression
performance issues.
Damian resolved LED blinking issues for X710T*L devices by adding
specific flows for these devices in the LED operations.
Navid Emamdoost found where allocated memory is not being properly freed
upon a failure in setting up MAC VLANs, so added the missing kfree().
v2: Dropped patches 2 & 6 from the original series while we wait for the
author to respond to community feedback.
