The logic that polls for the firmware message response uses a shorter
sleep interval for the first few passes. But there was a typo so it
was using the wrong counter (larger counter) for these short sleep
passes. The result is a slightly shorter timeout period for these
firmware messages than intended. Fix it by using the proper counter.

NFP BPF JIT compiler is doing a couple of small optimizations when jitting
ALU imm instructions, some of these optimizations could save code-gen, for
example:
A & -1 = A
A | 0 = A
A ^ 0 = A
However, for ALU32, high 32-bit of the 64-bit register should still be
cleared according to ISA semantics.

In Virtual Ethernet Port Aggregator (VEPA) mode, the packet skips
the system internal virtual switch and forwards to external network
switch. In Mellanox HCA case, the virtual switch is the HCA's Eswitch.
To support this, an new FDB flow table are created with level 0 and
linked to the existing FDB flow table in legacy mode. By default,
VEPA is turned off and this FDB flow table is empty. When VEPA is
turned on, two rules are created. One rule to forward on uplink vport
traffic to the legacy FDB. The other rule forward all other traffic
to uplink vport.
Other design alternatives were not chosen as explained below:
1. Create a forward rule in ACL flow table (most efficient design).
This approach is the not chosen because firmware does not support
forward rule to uplink vport (0xffff) for ACL flow table.
2. Add additional source port criteria in all the FDB rules to make the
FDB rules to be received rules only. This approach is not chosen because
it is not efficient as there can many rules in the FDB and VEPA mode
cannot be controlled per vport.
3. Add a highest prioirty flow group in the existing legacy FDB Flow
Table instead of a new flow table. This approoach does not work because the
new flow group has the same match criteria as the promiscuous flow group
and mlx5_add_flow_rules does not allow specifying flow group.

When TX reporter was introduced, it took ownership over TX timeout error
handling. this introduced a regression in case TX reporter is not valid
(NET_DEVLINK is not set, or devlink_health_reporter_create failure).
Fix mlx5e_tx_reporter_timeout function so it can be called at all times.
In addition, remove a warning print that indicates that a TX timeout won't
be handled in case of no valid TX reporter.

Flow entropy is calculated on the inner packet headers and used for
flow distribution in processing, routing etc. For GRE-type
encapsulations the entropy value is placed in the eight LSB of the key
field in the GRE header as defined in NVGRE RFC 7637. For UDP based
encapsulations the entropy value is placed in the source port of the
UDP header.
The hardware may support entropy calculation specifically for GRE and
for all tunneling protocols. With commit df2ef3bff193 ("net/mlx5e: Add
GRE protocol offloading") GRE is offloaded, but the hardware is
configured by default to calculate flow entropy so packets transmitted
on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN),
GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the
hardware behaviour must be controlled by the driver.
Ensure port entropy calculation is enabled for offloaded VXLAN tunnels
and disable port entropy calculation in the presence of offloaded GRE
tunnels by monitoring the presence of entropy enabling tunnels (i.e
VXLAN) and entropy disabing tunnels (i.e GRE).

Currently changing a PCMR field is done by setting the field in a

Fix this behaviour by modifying only the required field after first
reading the current register values, as a pre-step towards using more

Kalle Valo says:
====================
wireless-drivers-next patches for 5.1
Most likely the last set of patches for 5.1. WPA3 support to ath10k
and qtnfmac. FTM support to iwlwifi and ath10k. And of course other
new features and bugfixes.
wireless-drivers was merged due to dependency in mt76.
Major changes:
iwlwifi
* HE radiotap
* FTM (Fine Timing Measurement) initiator and responder implementation
* bump supported firmware API to 46
* VHT extended NSS support
* new PCI IDs for 9260 and 22000 series
ath10k
* change QMI interface to support the new (and backwards incompatible)
interface from HL3.1 and used in recent HL2.0 branch firmware
releases
* support WPA3 with WCN3990
* support for mac80211 airtime fairness based on transmit rate
estimation, the firmware needs to support WMI_SERVICE_PEER_STATS to
enable this
* report transmit airtime to mac80211 with firmwares having
WMI_SERVICE_REPORT_AIRTIME feature, this to have more accurate
airtime fairness based on real transmit time (instead of just
estimated from transmit rate)
* support Fine Timing Measurement (FTM) responder role
* add dynamic VLAN support with firmware having WMI_SERVICE_PER_PACKET_SW_ENCRYPT
* switch to use SPDX license identifiers
ath
* add new country codes for US
brcmfmac
* support monitor frames with the hardware/ucode header
qtnfmac
* enable WPA3 SAE and OWE support
mt76
* beacon support for USB devices (mesh+ad-hoc only)
rtlwifi
* convert to use SPDX license identifiers
libertas_tf
* get the MAC address before registering the device

If the socket was created with socket(AF_PACKET, SOCK_RAW, 0),
skb->protocol will be unset, __skb_flow_dissect() will fail, and
skb_probe_transport_header() will fall back to the offset_hint, making
the resulting skb_transport_offset incorrect.
If, however, there is no transport header in the packet,
transport_header shouldn't be set to an arbitrary value.
Fix it by leaving the transport offset unset if it couldn't be found, to
be explicit rather than to fill it with some wrong value. It changes the
behavior, but if some code relied on the old behavior, it would be
broken anyway, as the old one is incorrect.

private for each of them.
Having one work queue for receive mode configuration ndo_set_rx_mode()
call for all VFs results in making each of them wait till the
set_rx_mode() call completes for another VF if any of close, set
receive mode and change flags calls being already invoked. Potentially
this could cause device state change before appropriate call of receive
mode configuration completes, so the call itself became meaningless,
corrupt data or break configuration sequence.
We don't need any delays in NIC VF configuration sequence so having delayed
work call with 0 delay has no sense.
This commit is to implement one work queue for each NIC VF for set_rx_mode
task and to let them work independently and replacing delayed_work
with work_struct.

When running Docker with userns isolation e.g. --userns-remap="default"
and spawning up some containers with CAP_NET_ADMIN under this realm, I
noticed that link changes on ipvlan slave device inside that container
can affect all devices from this ipvlan group which are in other net
namespaces where the container should have no permission to make changes
to, such as the init netns, for example.
This effectively allows to undo ipvlan private mode and switch globally to
bridge mode where slaves can communicate directly without going through
hostns, or it allows to switch between global operation mode (l2/l3/l3s)
for everyone bound to the given ipvlan master device. libnetwork plugin
here is creating an ipvlan master and ipvlan slave in hostns and a slave
each that is moved into the container's netns upon creation event.

Same l3 -> l2 switch would also happen by creating another slave inside

One way to mitigate it is to check CAP_NET_ADMIN permissions of
the ipvlan master device's ns, and only then allow to change
mode or flags for all devices bound to it. Above two cases are
then disallowed after the patch.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = alloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it is
removed.
This code was detected with the help of Coccinelle.

Current code already set .min_uV and .uV_step fields and it actually can
use regulator_list_voltage_linear.
So remove buck_volt_range and use regulator_list_voltage_linear instead.

Libudev relies on having a subsystem link for non-root devices. To
avoid libudev (and potentially other userspace tools) choking on the
matrix device let us introduce a matrix bus and with it the matrix
bus subsytem. Also make the matrix device reside within the matrix
bus.
Doing this we remove the forced link from the matrix device to the
vfio_ap driver and the device_type we do not need anymore.
Since the associated matrix driver is not the vfio_ap driver any more,
we have to change the search for the devices on the vfio_ap driver in
the function vfio_ap_verify_queue_reserved.

The current content of some of the driver messages and the way that they
are issued results in some confusion, especially in the area of the PSP
as it relates to SEV support. If SEV is not supported, a message is issued
that says "psp initialization failed." This makes it seem like there was
a problem, when in fact, the PSP support is just disabled if SEV is not
supported.
Update the driver to check SEV support a bit earlier and issue a debug-
level message if SEV is not supported, followed by a debug-level message
that the PSP is disabled. This way you will only see PSP messages if SEV
is supported or if debug information is desired. Also, remove the overall
"enabled" and "disabled" messages for the driver and rely on the CCP and
PSP support to issue component-specific messages.
