9ba7ffa6d8 Merge branch 'marvell10g-updates'
Marek Behún says:

====================
net: phy: marvell10g updates

Here are some updates for marvell10g PHY driver.

I am still working on some more changes for this driver, but I would
like to have at least something reviewed / applied.

Changes since v3:
- added Andrew's Reviewed-by tags
- removed patches adding variadic-macro library and bitmap
  initialization macro - it causes warning that we are not currently
  able to fix easily. Instead the supported_interfaces bitmap is now
  initialized via a chip specific method
- added explanation of mactype initialization to commit message of patch
  07/16
- fixed repeated word in commit message of second to last patch

Changes since v2:
- code refactored to use an additional structure mv3310_chip describing
  mv3310 specific properties / operations for PHYs supported by this
  driver
- added separate phy_driver structures for 88X3340 and 88E2111
- removed 88E2180 specific code (dual-port and quad-port SXGMII modes
  are ignored for now)

Changes since v1:
- added various MACTYPEs support also for 88E21XX
- differentiate between specific models with same PHY_ID
- better check for compatible interface
- print exact model

298b58f00c 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.

Marc Kleine-Budde says:

====================
pull-request: can-next 2021-04-07

this is a pull request of 6 patches for net-next/master.

The first patch targets the CAN driver infrastructure, it improves the
alloc_can{,fd}_skb() function to set the pointer to the CAN frame to
NULL if skb allocation fails.

The next patch adds missing error handling to the m_can driver's RX
path (the code was introduced in -next, no need to backport).

In the next patch an unused constant is removed from an enum in the
c_can driver.

The last 3 patches target the mcp251xfd driver. They add BQL support
and try to work around a sometimes broken CRC when reading the TBC
register.

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.
 
 MLX5 sample HW offload - MLX5 driver patches
 --------------------------------------------
 
 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.

====================
mlx5-updates-2021-04-06

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.

MLX5 sample HW offload - MLX5 driver patches
--------------------------------------------

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.

872fff333f nfc/fdp: remove unnecessary assignment and label
In function fdp_nci_patch_otp and fdp_nci_patch_ram,many goto
out statements are used, and out label just return variable r.
in some places,just jump to the out label, and in other places,
assign a value to the variable r,then jump to the out label.
It is unnecessary, we just use return sentences to replace goto
sentences and delete out label.

d567fd6e82 mlxsw: core: Remove critical trip points from thermal zones
Disable software thermal protection by removing critical trip points
from all thermal zones.

The software thermal protection is redundant given there are two layers
of protection below it in firmware and hardware. The first layer is
performed by firmware, the second, in case firmware was not able to
perform protection, by hardware.
The temperature threshold set for hardware protection is always higher
than for firmware.

====================
mptcp: Cleanup, a new test case, and header trimming

Some more patches to include from the MPTCP tree:

Patches 1-6 refactor an address-related data structure and reduce some
duplicate code that handles IPv4 and IPv6 addresses.

Patch 7 adds a test case for the MPTCP netlink interface, passing a
specific ifindex to the kernel.

Patch 8 drops extra header options from IPv4 address echo packets,
improving consistency and testability between IPv4 and IPv6.

Current Linux carries echo-ed ADD_ADDR over pure TCP ACKs, so there is no
need to add a DSS element that would fit only ADD_ADDR with IPv4 address.
Drop the DSS from echo-ed ADD_ADDR, regardless of the IP version.

f7dafee185 mptcp: use mptcp_addr_info in mptcp_options_received
This patch added a new struct mptcp_addr_info member addr in struct
mptcp_options_received, and dropped the original family, addr_id, addr,
addr6 and port fields in it. Then we can pass the parameter mp_opt.addr
directly to mptcp_pm_add_addr_received and mptcp_pm_add_addr_echoed.

Since the port number became big-endian now, use htons to convert the
incoming port number to it. Also use ntohs to convert it when passing
it to add_addr_generate_hmac or printing it out.
