liquidio: Fix unintented sign extension of a left shift of a u16
The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port
(a u16) left 24 places. There are two subtle issues here, first the
shift gets promoted to an signed int and then sign extended to a u64.
If oct->pcie_port is 0x80 or more then the upper bits get sign extended
to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it
needs to be cast to a u64 for all the bits to not overflow.
It is entirely possible that the u16 port value is never large enough
for this to fail, but it is useful to fix unintended overflows such
as this.
Fix this by casting the port parameter to the macro to a u64 before
the shift.

Introduce TC sample offload
Background
----------
The tc sample action allows user to sample traffic matched by tc
classifier. The sampling consists of choosing packets randomly and
sampling them using psample module.
The tc sample parameters include group id, sampling rate and packet's
truncation (to save kernel-user traffic).
Sample in TC SW
---------------
User must specify rate and group id for sample action, truncate is
optional.
tc filter add dev enp4s0f0_0 ingress protocol ip prio 1 flower \
src_mac 02:25:d0:14:01:02 dst_mac 02:25:d0:14:01:03 \
action sample rate 10 group 5 trunc 60 \
action mirred egress redirect dev enp4s0f0_1
The tc sample action kernel module 'act_sample' will call another
kernel module 'psample' to send sampled packets to userspace.
The sample action is translated to a goto flow table object
destination which samples packets according to the provided
sample ratio. Sampled packets are duplicated. One copy is
processed by a termination table, named the sample table,
which sends the packet to the eswitch manager port (that will
be processed by software).
The second copy is processed by the default table which executes
the subsequent actions. The default table is created per <vport,
chain, prio> tuple as rules with different prios and chains may
overlap.
For example, for the following typical flow table:
+-------------------------------+
+ original flow table +
+-------------------------------+
+ original match +
+-------------------------------+
+ sample action + other actions +
+-------------------------------+
We translate the tc filter with sample action to the following HW model:
+---------------------+
+ original flow table +
+---------------------+
+ original match +
+---------------------+
|
v
+------------------------------------------------+
+ Flow Sampler Object +
+------------------------------------------------+
+ sample ratio +
+------------------------------------------------+
+ sample table id | default table id +
+------------------------------------------------+
| |
v v
+-----------------------------+ +----------------------------------------+
+ sample table + + default table per <vport, chain, prio> +
+-----------------------------+ +----------------------------------------+
+ forward to management vport + + original match +
+-----------------------------+ +----------------------------------------+
+ other actions +
+----------------------------------------+
Flow sampler object
-------------------
Hardware introduces flow sampler object to do sample. It is a new
destination type. Driver needs to specify two flow table ids in it.
One is sample table id. The other one is the default table id.
Sample table samples the packets according to the sample rate and
forward the sampled packets to eswitch manager port. Default table
finishes the subsequent actions.
Group id and reg_c0
-------------------
Userspace program will take different actions for sampled packets
according to tc sample action group id. So hardware must pass group
id to software for each sampled packets. In Paul Blakey's "Introduce
connection tracking offload" patch set, reg_c0 lower 16 bits are used
for miss packet chain id restore. We convert reg_c0 lower 16 bits to
a common object pool, so other features can also use it.
Since sample group id is 32 bits, create a 16 bits object id to map
the group id and write the object id to reg_c0 lower 16 bits. reg_c0
can only be used for matching. Write reg_c0 to flow_tag, so software
can get the object id via flow_tag and find group id via the common
object pool.
Sampler restore handle
----------------------
Use common object pool to create an object id to map sample parameters.
Allocate a modify header action to write the object id to reg_c0 lower
16 bits. Create a restore rule to pass the object id to software. So
software can identify sampled packets via the object id and send it to
userspace.
Aggregate the modify header action, restore rule and object id to a
sample restore handle. Re-use identical sample restore handle for
the same object id.
Send sampled packets to userspace
---------------------------------
The destination for sampled packets is eswitch manager port, so
representors can receive sampled packets together with the group id.
Driver will send sampled packets and group id to userspace via psample.

can: mcp251xfd: mcp251xfd_regmap_crc_read(): work around broken CRC on TBC register
MCP251XFD_REG_TBC is the time base counter register. It increments
once per SYS clock tick, which is 20 or 40 MHz. Observation shows that
if the lowest byte (which is transferred first on the SPI bus) of that
register is 0x00 or 0x80 the calculated CRC doesn't always match the
transferred one.
To reproduce this problem let the driver read the TBC register in a
high frequency. This can be done by attaching only the mcp251xfd CAN
controller to a valid terminated CAN bus and send a single CAN frame.
As there are no other CAN controller on the bus, the sent CAN frame is
not ACKed and the mcp251xfd repeats it. If user space enables the bus
error reporting, each of the NACK errors is reported with a time
stamp (which is read from the TBC register) to user space.
$ ip link set can0 down
$ ip link set can0 up type can bitrate 500000 berr-reporting on
$ cansend can0 4FF#ff.01.00.00.00.00.00.00
If the highest bit in the lowest byte is flipped the transferred CRC
matches the calculated one. We assume for now the CRC calculation in
the chip works on wrong data and the transferred data is correct.
This patch implements the following workaround:
- If a CRC read error on the TBC register is detected and the lowest
byte is 0x00 or 0x80, the highest bit of the lowest byte is flipped
and the CRC is calculated again.
- If the CRC now matches, the _original_ data is passed to the reader.
For now we assume transferred data was OK.

can: skb: alloc_can{,fd}_skb(): set "cf" to NULL if skb allocation fails
The handling of CAN bus errors typically consist of allocating a CAN
error SKB using alloc_can_err_skb() followed by stats handling and
filling the error details in the newly allocated CAN error SKB. Even
if the allocation of the SKB fails the stats handling should not be
skipped.
The common pattern in CAN drivers is to allocate the skb and work on
the struct can_frame pointer "cf", if it has been assigned by
alloc_can_err_skb().
In case of an OOM alloc_can_err_skb() returns NULL, but doesn't set
"cf" to NULL as well. For the above pattern to work the "cf" has to be
initialized to NULL, which is easily forgotten.
To solve this kind of problems, set "cf" to NULL if
alloc_can_err_skb() returns NULL.

Until very recently, the usbnet framework only had support functions
for devices which reported the link speed by explicitly querying the

expose the PHY (or modem) directly.

query state recorded by the cdc_ether driver were added in a previous patch.
Instead of cdc_ether spewing the link speed into the dmesg buffer,
record the link speed encoded in these notifications and tell the
usbnet framework to use the new functions to get link speed/state.
User space can now get the most recent link speed/state using ethtool.

to specify ifindex when a device is moved to another network namespace.
Even now, a device ifindex can be changed if there is another device
with the same ifindex in the target namespace. So this change doesn't
introduce completely new behavior, it adds more control to the process.
CRIU users want to restore containers with pre-created network devices.
A user will provide network devices and instructions where they have to
be restored, then CRIU will restore network namespaces and move devices
into them. The problem is that devices have to be restored with the same
indexes that they have before C/R.

mld: change lockdep annotation for ip6_sf_socklist and ipv6_mc_socklist
struct ip6_sf_socklist and ipv6_mc_socklist are per-socket MLD data.
These data are protected by rtnl lock, socket lock, and RCU.
So, when these are used, it verifies whether rtnl lock is acquired or not.
ip6_mc_msfget() is called by do_ipv6_getsockopt().
But caller doesn't acquire rtnl lock.
So, when these data are used in the ip6_mc_msfget() lockdep warns about it.
But accessing these is actually safe because socket lock was acquired by
do_ipv6_getsockopt().
So, it changes lockdep annotation from rtnl lock to socket lock.
(rtnl_dereference -> sock_dereference)
Locking graph for mld data is like below:
When writing mld data:
do_ipv6_setsockopt()
rtnl_lock
lock_sock
(mld functions)
idev->mc_lock(if per-interface mld data is modified)
When reading mld data:

net: x25: Queue received packets in the drivers instead of per-CPU queues
X.25 Layer 3 (the Packet Layer) expects layer 2 to provide a reliable
datalink service such that no packets are reordered or dropped. And
X.25 Layer 2 (the LAPB layer) is indeed designed to provide such service.
However, this reliability is not preserved when a driver calls "netif_rx"
to deliver the received packets to layer 3, because "netif_rx" will put
the packets into per-CPU queues before they are delivered to layer 3.
If there are multiple CPUs, the order of the packets may not be preserved.
The per-CPU queues may also drop packets if there are too many.
Therefore, we should not call "netif_rx" to let it queue the packets.
Instead, we should use our own queue that won't reorder or drop packets.
This patch changes all X.25 drivers to use their own queues instead of
calling "netif_rx". The patch also documents this requirement in the
"x25-iface" documentation.

This patch adds the initial XDP support to stmmac driver. It supports
XDP_PASS, XDP_DROP and XDP_ABORTED actions. Upcoming patches will add
support for XDP_TX and XDP_REDIRECT.
To support XDP headroom, this patch adds page_offset into RX buffer and
change the dma_sync_single_for_device|cpu(). The DMA address used for
RX operation are changed to take into page_offset too. As page_pool
can handle dma_sync_single_for_device() on behalf of driver with
PP_FLAG_DMA_SYNC_DEV flag, we skip doing that in stmmac driver.
Current stmmac driver supports split header support (SPH) in RX but
the flexibility of splitting header and payload at different position
makes it very complex to be supported for XDP processing. In addition,
jumbo frame is not supported in XDP to keep the initial codes simple.
This patch has been tested with the sample app "xdp1" located in
samples/bpf directory for both SKB and Native (XDP) mode. The burst
traffic generated using pktgen_sample03_burst_single_flow.sh in
samples/pktgen directory.
