d2be320495 net: dsa: modularize DSA_TAG_PROTO_NONE
There is no reason that I can see why the no-op tagging protocol should
be registered manually, so make it a module and make all drivers which
have any sort of reference to DSA_TAG_PROTO_NONE select it.

Note that I don't know if ksz_get_tag_protocol() really needs this,
or if it's just the logic which is poorly written. All switches seem to
have their own tagging protocol, and DSA_TAG_PROTO_NONE is just a
fallback that never gets used.

339e79dfb0 Merge branch 'cleanup-ocelot_stats-exposure'
Colin Foster says:

====================
cleanup ocelot_stats exposure

The ocelot_stats structures became redundant across all users. Replace
this redundancy with a static const struct. After doing this, several
definitions inside include/soc/mscc/ocelot.h no longer needed to be
shared. Patch 2 removes them.

Checkpatch throws an error for a complicated macro not in parentheses. I
understand the reason for OCELOT_COMMON_STATS was to allow expansion, but
interestingly this patch set is essentially reverting the ability for
expansion. I'm keeping the macro in this set, but am open to remove it,
since it doesn't _actually_ provide any immediate benefits anymore.

674b3e1642 octeontx2-pf: Add additional checks while configuring ucast/bcast/mcast rules
1. If a profile does not support DMAC extraction then avoid installing NPC
flow rules for unicast. Similarly, if LXMB(L2 and L3) extraction is not
supported by the profile then avoid installing broadcast and multicast
rules.
2. Allow MCAM entry insertion for promiscuous mode.
3. For the profiles where DMAC is not extracted in MKEX key default
unicast entry installed by AF is not valid. Hence do not use action
from the AF installed default unicast entry for such cases.
4. Adjacent packet header fields in a packet like IP header source
and destination addresses or UDP/TCP header source port and destination
can be extracted together in MKEX profile. Therefore MKEX profile can be
configured to in two ways:
	a. Total of 4 bytes from start of UDP header(src port
	   + destination port)
	or
	b. Two bytes from start and two bytes from offset 2

I was mistaken how atomic64_try_cmpxchg(&sk_cookie, &res, new)

I was assuming @res would contain the final sk_cookie value,

We could do something like:

if (atomic64_try_cmpxchg(&sk_cookie, &res, new)
	res = new;

But we can avoid a conditional and read sk_cookie again.

atomic64_cmpxchg(&sk_cookie, res, new);
res = atomic64_read(&sk_cookie);

netdev.vger.kernel.org archive mirror
Steen Hegelund says:

====================
net: Add support for VCAP debugFS in Sparx5

This provides support for getting VCAP instance, VCAP rule and VCAP port
keyset configuration information via the debug file system.

It builds on top of the initial IS2 VCAP support found in these series:

https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/20221111130519.1459549-1-steen.hegelund@microchip.com/

Functionality:
==============

The VCAP API exposes a /sys/kernel/debug/sparx5/vcaps folder containing
the following entries:

- raw_<vcap>_<instance>
    This is a raw dump of the VCAP instance with a line for each available
    VCAP rule.  This information is limited to the VCAP rule address, the
    rule size and the rule keyset name as this requires very little
    information from the VCAP cache.

    This can be used to detect if a valid rule is stored at the correct
    address.

- <vcap>_<instance>
    This dumps the VCAP instance configuration: address ranges, chain id
    ranges, word size of keys and actions etc, and for each VCAP rule the
    details of keys (values and masks) and actions are shown.

    This is useful when discovering if the expected rule is present and in
    which order it will be matched.

- <interface>
    This shows the keyset configuration per lookup and traffic type and the
    set of sticky bits (common for all interfaces). This is cleared when
    shown, so it is possible to sample over a period of time.

    It also shows if this port/lookup is enabled for matching in the VCAP.

    This can be used to find out which keyset the traffic being sent to a
    port, will be matched against, and if such traffic has been seen by one
    of the ports.

Delivery:
=========

This is current plan for delivering the full VCAP feature set of Sparx5:

- TC protocol all support for IS2 VCAP
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
  upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support

Version History:
================
v2      Removed a 'support' folder (used for integration testing) that had
        been added in patch 6/8 by a mistake.
        Wrapped long lines.

1. Fix coding style, and make probing of the driver fail if MDC overflow
--- v2 ---
1. Use clock-frequency, as defined in mdio.yaml, to configure MDIO
   clock.
2. Only print out frequency if it is set to a non-standard value.
3. Reduce the scope of axienet_mdio_enable and remove
   axienet_mdio_disable because no one really uses it anymore.

2e1f2c1066 net: axienet: set mdio clock according to bus-frequency
Some FPGA platforms have 80KHz MDIO bus frequency constraint when
connecting Ethernet to its on-board external Marvell PHY. Thus, we may
have to set MDIO clock according to the DT. Otherwise, use the default
2.5 MHz, as specified by 802.3, if the entry is not present.

Also, change MAX_MDIO_FREQ to DEFAULT_MDIO_FREQ because we may actually
set MDIO bus frequency higher than 2.5MHz if undelying devices support
it. And properly disable the mdio bus clock in error path.

Smatch complains that:

    sparx5_dcb_apptrust_validate() error: uninitialized symbol 'match'.

This would only happen if the:

	if (sparx5_dcb_apptrust_policies[i].nselectors != nselectors)

condition is always true (they are not equal).  The "nselectors"
variable comes from dcbnl_ieee_set() and it is a number between 0-256.
This seems like a probably a real bug.

this series adds support for IPsec offload to the NFP driver.

It covers three enhancements:

1. Patches 1/3:
   - Extend the capability word and control word to to support
     new features.

2. Patch 2/3:
   - Add framework to support IPsec offloading for NFP driver,
     but IPsec offload control plane interface xfrm callbacks which
     interact with upper layer are not implemented in this patch.

3. Patch 3/3:
   - IPsec control plane interface xfrm callbacks are implemented
     in this patch.

Changes since v3
* Remove structure fields that describe firmware but
  are not used for Kernel offload
* Add WARN_ON(!xa_empty()) before call to xa_destroy()
* Added helpers for hash methods

Changes since v2
* OFFLOAD_HANDLE_ERROR macro and the associated code removed
* Unnecessary logging removed
* Hook function xdo_dev_state_free in struct xfrmdev_ops removed
* Use Xarray to maintain SA entries

Changes since v1
* Explicitly return failure when XFRM_STATE_ESN is set
* Fix the issue that AEAD algorithm is not correctly offloaded

for other use.

8719a1c30d bna: Avoid clashing function prototypes
When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].

Fix a total of 227 warnings like these:

drivers/net/ethernet/brocade/bna/bna_enet.c:519:3: warning: cast from 'void (*)(struct bna_ethport *, enum bna_ethport_event)' to 'bfa_fsm_t' (aka 'void (*)(void *, int)') converts to incompatible function type [-Wcast-function-type-strict]
                bfa_fsm_set_state(ethport, bna_ethport_sm_down);
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The bna state machine code heavily overloads its state machine functions,
so these have been separated into their own sets of structs, enums,
typedefs, and helper functions. There are almost zero binary code changes,
all seem to be related to header file line numbers changing, or the
addition of the new stats helper.

Important to mention is that while I was manually implementing this changes
I was staring at this[2] patch from Kees Cook. Thanks, Kees. :)

f63959c7ee net: ethernet: mtk_eth_soc: implement multi-queue support for per-port queues
When sending traffic to multiple ports with different link speeds, queued
packets to one port can drown out tx to other ports.
In order to better handle transmission to multiple ports, use the hardware
shaper feature to implement weighted fair queueing between ports.
Weight and maximum rate are automatically adjusted based on the link speed
of the port.
The first 3 queues are unrestricted and reserved for non-DSA direct tx on
GMAC ports. The following queues are automatically assigned by the MTK DSA
tag driver based on the target port number.
The PPE offload code configures the queues for offloaded traffic in the same
way.
This feature is only supported on devices supporting QDMA. All queues still
share the same DMA ring and descriptor pool.
