When PVID is removed from a bridge port, the Linux bridge drops both
untagged and prio-tagged packets. Align mlxsw with this behavior.

Due to an issue on Spectrum-2, in front-panel ports split four ways, 2 out
of 32 port buffers cannot be used. To work around this, the next FW release
will mark them as unused, and will report correspondingly lower total
shared buffer size. mlxsw will pick up the new value through a query to
cap_total_buffer_size resource. However the initial size for shared buffer
pool 0 is hard-coded and therefore needs to be updated.
Thus reduce the pool size by 2.7 MiB (which corresponds to 2/32 of the
total size of 42 MiB), and round down to the whole number of cells.

The driver tries to periodically refresh neighbours that are used to
reach nexthops. This is done by periodically calling neigh_event_send().
However, if the neighbour becomes dead, there is nothing we can do to
return it to a connected state and the above function call is basically
a NOP.
This results in the nexthop never being written to the device's
adjacency table and therefore never used to forward packets.
Fix this by dropping our reference from the dead neighbour and
associating the nexthop with a new neigbhour which we will try to
refresh.

The same hash function and seed are used for both ECMP and LAG hash.
Therefore, when a LAG device is used as a nexthop device as part of an
ECMP group, hash polarization can occur and all the traffic will be
hashed to a single LAG slave.

In commit a07966447f39 ("geneve: ICMP error lookup handler") I wrongly
assumed buffers from icmp_socket_deliver() would be linear. This is not
the case: icmp_socket_deliver() only guarantees we have 8 bytes of linear

Packets received at the NFP driver may be redirected to egress of another
netdev (e.g. in the case of OvS internal ports). On the egress path, some
processes, like TC egress hooks, may expect the network header offset
field in the skb to be correctly set. If this is not the case there is
potential for abnormal behaviour and even the triggering of BUG() calls.

Commit 31dd83b96641 ("net-next: phy: new Asix Electronics PHY driver")
introduced a new PHY driver drivers/net/phy/asix.c that causes a module
name conflict with a pre-existiting driver (drivers/net/usb/asix.c).
The PHY driver is used by the X-Surf 100 ethernet card driver, and loaded

The TX queue index returned by the fallback function ranges
between [0,NUM CHANNELS - 1] if QoS isn't set and
[0, (NUM CHANNELS)*(NUM TCs) -1] otherwise.
Our HW uses different TC mapping than the fallback function
(which is denoted as 'up', user priority) so we only need to extract
a channel number out of the returned value.
Since (NUM CHANNELS)*(NUM TCs) is a relatively small number, using
reciprocal scale almost always returns zero.
We instead access the 'txq2sq' table to extract the sq (and with it the
channel number) associated with the tx queue, thus getting
a more evenly distributed channel number.

in that case we will end up proceeding with adding an new device that no
one was expecting to remove, leaving behind used resources such as EQs that
causes a failure to destroy comp EQs and syndrome (0x30f433).
Fix that by making sure that we try to remove and add a device (based on a

Currently the following message is observed when the flexcan
driver is probed:
flexcan 2090000.flexcan: device registered (reg_base=(ptrval), irq=23)
The reason for printing 'ptrval' is explained at
Documentation/core-api/printk-formats.rst:
"Pointers printed without a specifier extension (i.e unadorned %p) are
hashed to prevent leaking information about the kernel memory layout. This
has the added benefit of providing a unique identifier. On 64-bit machines
the first 32 bits are zeroed. The kernel will print ``(ptrval)`` until it
gathers enough entropy."
Instead of passing %pK, which can print the correct address, simply
remove the entire message as it is not really that useful.

During frame reception while the MCAN is in Error Passive state and the
Receive Error Counter has thevalue MCAN_ECR.REC = 127, it may happen
that MCAN_IR.MRAF is set although there was no Message RAM access
failure. If MCAN_IR.MRAF is enabled, an interrupt to the Host CPU is
generated.
Work around:
The Message RAM Access Failure interrupt routine needs to check whether
MCAN_ECR.RP = '1' and MCAN_ECR.REC = '127'.
In this case, reset MCAN_IR.MRAF. No further action is required.
This affects versions older than 3.2.0

Reproducibility: If 2 devices with m_can are connected back to back,

A link change request failed with some changes committed already.
Interface can0 may have been left with an inconsistent configuration,
please check.
| RTNETLINK answers: Connection timed out
It is caused by calling of flexcan_chip_unfreeze() timeout.
Originally the code is using usleep_range(10, 20) for unfreeze
operation, but the patch (8badd65 can: flexcan: avoid calling
usleep_range from interrupt context) changed it into udelay(10) which is
only a half delay of before, there're also some other delay changes.
After double to FLEXCAN_TIMEOUT_US to 100 can fix the issue.
Meanwhile, Rasmus Villemoes reported that even with a timeout of 100,
flexcan_probe() fails on the MPC8309, which requires a value of at least
140 to work reliably. 250 works for everyone.

First set of fixes for 5.2. Most important here are buffer overflow
fixes for mwifiex.
rtw88
* fix out of bounds compiler warning
* fix rssi handling to get 4x more throughput
* avoid circular locking
rsi
* fix unitilised data warning, these are hopefully the last ones so
that the warning can be enabled by default
mwifiex
* fix buffer overflows
iwlwifi
* remove not used debugfs file
* various fixes

Revert "fib_rules: return 0 directly if an exactly same rule exists when NLM_F_EXCL not supplied"
net: aquantia: fix wol configuration not applied sometimes
ethtool: fix potential userspace buffer overflow
Fix memory leak in sctp_process_init
net: rds: fix memory leak when unload rds_rdma
ipv6: fix the check before getting the cookie in rt6_get_cookie
ipv4: not do cache for local delivery if bc_forwarding is enabled
s390/qeth: handle error when updating TX queue count
s390/qeth: fix VLAN attribute in bridge_hostnotify udev event
s390/qeth: check dst entry before use

...
Use a safe strscpy call to copy the ethtool stat strings into the
relevant buffers, instead of a memcpy that will be accessing
out-of-bound data.

WoL magic packet configuration sometimes does not work due to
couple of leakages found.
Mainly there was a regression introduced during readx_poll refactoring.
Next, fw request waiting time was too small. Sometimes that
caused sleep proxy config function to return with an error
and to skip WoL configuration.
At last, WoL data were passed to FW from not clean buffer.
That could cause FW to accept garbage as a random configuration data.
