Fix this by making the constant unsigned, to match the type of "len".
While at it, replace the other missed ternary operator by min(), too.
Convert the dummy PRINT_PKT() from a macro to a static inline function,
to catch mistakes like this without having to enable debug options

The AST2600 when using the i210 NIC over NC-SI has been observed to
produce incorrect checksum results with specific MTU values. This was
first observed when sending data across a long distance set of networks.
On a local network, the following test was performed using a 1MB file of
random data.
On the receiver run this script:
#!/bin/bash
while [ 1 ]; do
# Zero the stats
nstat -r > /dev/null
nc -l 9899 > test-file
# Check for checksum errors
TcpInCsumErrors=$(nstat | grep TcpInCsumErrors)
if [ -z "$TcpInCsumErrors" ]; then
echo No TcpInCsumErrors
else
echo TcpInCsumErrors = $TcpInCsumErrors
fi
done
On an AST2600 system:
# nc <IP of receiver host> 9899 < test-file
The test was repeated with various MTU values:
# ip link set mtu 1410 dev eth0
The observed results:
1500 - good
1434 - bad
1400 - good
1410 - bad
1420 - good
The test was repeated after disabling tx checksumming:
# ethtool -K eth0 tx-checksumming off
And all MTU values tested resulted in transfers without error.
An issue with the driver cannot be ruled out, however there has been no
bug discovered so far.
David has done the work to take the original bug report of slow data
transfer between long distance connections and triaged it down to this
test case.
The vendor suspects this this is a hardware issue when using NC-SI. The
fixes line refers to the patch that introduced AST2600 support.

igb_read_phy_reg() will silently return, leaving phy_data untouched, if
hw->ops.read_reg isn't set. Depending on the uninitialized value of
phy_data, this led to the phy status check either succeeding immediately
or looping continuously for 2 seconds before emitting a noisy err-level
timeout. This message went out to the console even though there was no
actual problem.
Instead, first check if there is read_reg function pointer. If not,
proceed without trying to check the phy status register.

When removing the pn533 device (i2c or USB), there is a logic error. The
original code first cancels the worker (flush_delayed_work) and then
destroys the workqueue (destroy_workqueue), leaving the timer the last
one to be deleted (del_timer). This result in a possible race condition
in a multi-core preempt-able kernel. That is, if the cleanup
(pn53x_common_clean) is concurrently run with the timer handler
(pn533_listen_mode_timer), the timer can queue the poll_work to the
already destroyed workqueue, causing use-after-free.
This patch reorder the cleanup: it uses the del_timer_sync to make sure
the handler is finished before the routine will destroy the workqueue.
Note that the timer cannot be activated by the worker again.
static void pn533_wq_poll(struct work_struct *work)
...
rc = pn533_send_poll_frame(dev);
if (rc)
return;
if (cur_mod->len == 0 && dev->poll_mod_count > 1)
mod_timer(&dev->listen_timer, ...);
That is, the mod_timer can be called only when pn533_send_poll_frame()
returns no error, which is impossible because the device is detaching
and the lower driver should return ENODEV code.

====================
mptcp: Fix checksum byte order on little-endian
These patches address a bug in the byte ordering of MPTCP checksums on
little-endian architectures. The __sum16 type is always big endian, but
was being cast to u16 and then byte-swapped (on little-endian archs)
when reading/writing the checksum field in MPTCP option headers.
MPTCP checksums are off by default, but are enabled if one or both peers
request it in the SYN/SYNACK handshake.
The corrected code is verified to interoperate between big-endian and
little-endian machines.
Patch 1 fixes the checksum byte order, patch 2 partially mitigates
interoperation with peers sending bad checksums by falling back to TCP
instead of resetting the connection.

RFC 8684 section 3.7 describes several opportunities for a MPTCP
connection to "fall back" to regular TCP early in the connection
process, before it has been confirmed that MPTCP options can be
successfully propagated on all SYN, SYN/ACK, and data packets. If a peer
acknowledges the first received data packet with a regular TCP header
(no MPTCP options), fallback is allowed.
If the recipient of that first data packet finds a MPTCP DSS checksum
error, this provides an opportunity to fail gracefully with a TCP
fallback rather than resetting the connection (as might happen if a
checksum failure were detected later).
This commit modifies the checksum failure code to attempt fallback on
the initial subflow of a MPTCP connection, only if it's a failure in the
first data mapping. In cases where the peer initiates the connection,
requests checksums, is the first to send data, and the peer is sending
incorrect checksums (see
https://github.com/multipath-tcp/mptcp_net-next/issues/275), this allows
the connection to proceed as TCP rather than reset.

The MPTCP code typecasts the checksum value to u16 and
then converts it to big endian while storing the value into
the MPTCP option.
As a result, the wire encoding for little endian host is
wrong, and that causes interoperabilty interoperability
issues with other implementation or host with different endianness.
Address the issue writing in the packet the unmodified __sum16 value.
MPTCP checksum is disabled by default, interoperating with systems
with bad mptcp-level csum encoding should cause fallback to TCP.

armada-3720-turris-mox and orion-mdio
This is a follow up to the change that converted the orion-mdio dt-binding from
txt to DT schema format. At the time I thought the binding needed
'unevaluatedProperties: false' because the core mdio.yaml binding didn't handle
the DSA switches. In reality it was simply the invalid reg property causing the
downstream nodes to be unevaluated. Fixing the reg nodes means we can set
'unevaluatedProperties: true'

I don't know if you had a change for the reg properties in flight. I didn't see
anything on lore/lkml so sorry if this crosses with something you've done.

When the binding was converted it appeared necessary to set
'unevaluatedProperties: true' because of the switch devices on the
turris-mox board. Actually the error was because of the reg property
being incorrect causing the rest of the properties to be unevaluated.
After the reg properties are fixed for turris-mox we can set
'unevaluatedProperties: false' as is generally expected.

net: dsa: microchip: refactor the ksz switch init function
During the ksz_switch_register function, it calls the individual switches init

Eli Cohen Says:
===============
The multiport eswitch feature allows to forward traffic from a
representor net device to the uplink port of an associated eswitch's
uplink port.
This feature requires creating a LAG object. Since LAG can be created
only once for a function, the feature is mutual exclusive with either
bonding or multipath.
Multipath eswitch mode is entered automatically these conditions are
met:
1. No other LAG related mode is active.
2. A rule that explicitly forwards to an uplink port is inserted.
The implementation maintains a reference count on such rules. When the
reference count reaches zero, the LAG is released and other modes may be
used.
When an explicit rule that explicitly forwards to an uplink port is
inserted while another LAG mode is active, that rule will not be
offloaded by the hardware since the hardware cannot guarantee that the
rule will actually be forwarded to that port.
Example rules that forwards to an uplink port is:
$ tc filter add dev rep0 root flower action mirred egress \
redirect dev uplinkrep0
$ tc filter add dev rep0 root flower action mirred egress \
redirect dev uplinkrep1
This feature is supported only if LAG_RESOURCE_ALLOCATION firmware
configuration parameter is set to true.
The series consists of three patches:
1. Lag state machine refactor
This patch does not add new functionality but rather changes the way
the state of the LAG is maintained.
2. Small fix to remove unused argument.
3. The actual implementation of the feature.

Since the recent introduction supporting the SM3 and SM4 hash algos for IPsec, the kernel
produces invalid pfkey acquire messages, when these encryption modules are disabled. This
happens because the availability of the algos wasn't checked in all necessary functions.
This patch adds these checks.

If skb_clone() returns null pointer, pfkey_broadcast() will
return error.
Therefore, it should be better to check the return value of
pfkey_broadcast() and return error if fails.

Multiport eswitch mode is a LAG mode that allows to add rules that
forward traffic to a specific physical port without being affected by LAG
affinity configuration.
This mode of operation is mutual exclusive with the other LAG modes used
by multipath and bonding.
To make the transition between the modes, we maintain a counter on the
number of rules specifying one of the uplink representors as the target
of mirred egress redirect action.
An example of such rule would be:
$ tc filter add dev enp8s0f0_0 prot all root flower dst_mac \
00:11:22:33:44:55 action mirred egress redirect dev enp8s0f0
If the reference count just grows to one and LAG is not in use, we
create the LAG in multiport eswitch mode. Other mode changes are not
allowed while in this mode. When the reference count reaches zero, we
destroy the LAG and let other modes be used if needed.
logic also changed such that if forwarding to some uplink destination
cannot be guaranteed, we fail the operation so the rule will eventually
be in software and not in hardware.

LAG state machine is implemented using bit flags. However, all these bit
flags, except for MLX5_LAG_FLAG_HASH_BASED, are really mutual exclusive.
In addition, MLX5_LAG_FLAG_READY is used by bonding to mark if we have
our netdevices successfully added to lag and does not really belong in
the same flags variable as the other flags.
Rename MLX5_LAG_FLAG_READY to MLX5_LAG_FLAG_NDEVS_READY to better
reflect its purpose and put it in a new flags variable.
For the rest of the flags, we introduce a mode enum to hold the state
of the LAG.
Remove the shared fdb boolean flag from struct mlx5_lag and store this
configuration as a mode flag.
Change all flag related operations to use standard Linux APIs.

Connection offload is translated to multiple rules over several
hardware flow tables. Unhandled end-cases may cause a hardware
resource leak causing multiple system symptoms such as a host
memory leak, decreased performance and other scale related issues.
Export the current number of firmware FTEs related to the CT table
as a debugfs counter. Also add a dropped packets counter to help
debug packets dropped on restore failure.
To show the offloaded count:
cat /sys/kernel/debug/mlx5/<PCI>/ct_nic/offloaded
To show the dropped count:
cat /sys/kernel/debug/mlx5/<PCI>/ct_nic/rx_dropped

By PCI spec, the config space of the VF always report relaxed ordering
not supported while it inherits this property from its PF. Hence using
pcie_relaxed_ordering_enable(), always disables the relaxed ordering on
all VFs. Remove this check and rely on the firmware which queries the
config space of the PF and set the capability bit accordingly.

Offloading outer checksum on tunnels requires GSO partial, add it to
'vlan_features' to allow offloading tunnels over vlans.
For example, running GENEVE over vlan & ipv6 (mandatory UDP checksum)
now allows for hardware TSO instead of software segmentation in GSO
only.
