Core
 ----
 
  - More core refactoring to reduce the RTNL lock contention,
    including preparatory work for the per-network namespace RTNL lock,
    replacing RTNL lock with a per device-one to protect NAPI-related
    net device data and moving synchronize_net() calls outside such
    lock.
 
  - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and
    more specific TCP coverage.
 
  - Reduce network namespace tear-down time by removing per-subsystems
    synchronize_net() in tipc and sched.
 
  - Add flow label selector support for fib rules, allowing traffic
    redirection based on such header field.
 
 Netfilter
 ---------
 
  - Do not remove netdev basechain when last device is gone, allowing
    netdev basechains without devices.
 
  - Revisit the flowtable teardown strategy, dealing better with fin,
    reset and re-open events.
 
  - Scale-up IP-vs connection dumping by avoiding linear search on
    each restart.
 
 Protocols
 ---------
 
  - A significant XDP socket refactor, consolidating and optimizing
    several helpers into the core
 
  - Better scaling of ICMP rate-limiting, by removing false-sharing in
    inet peers handling.
 
  - Introduces netlink notifications for multicast IPv4 and IPv6
    address changes.
 
  - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
    aggregation and fragmentation of the inner IP.
 
  - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets,
    to avoid local port exhaustion issues when the average connection
    lifetime is very short.
 
  - Support updating keys (re-keying) for connections using kernel
    TLS (for TLS 1.3 only).
 
  - Support ipv4-mapped ipv6 address clients in smc-r v2.
 
  - Add support for jumbo data packet transmission in RxRPC sockets,
    gluing multiple data packets in a single UDP packet.
 
  - Support RxRPC RACK-TLP to manage packet loss and retransmission in
    conjunction with the congestion control algorithm.
 
 Driver API
 ----------
 
  - Introduce a unified and structured interface for reporting PHY
    statistics, exposing consistent data across different H/W via
    ethtool.
 
  - Make timestamping selectable, allow the user to select the desired
    hwtstamp provider (PHY or MAC) administratively.
 
  - Add support for configuring a header-data-split threshold (HDS)
    value via ethtool, to deal with partial or buggy H/W implementation.
 
  - Consolidate DSA drivers Energy Efficiency Ethernet support.
 
  - Add EEE management to phylink, making use of the phylib
    implementation.
 
  - Add phylib support for in-band capabilities negotiation.
 
  - Simplify how phylib-enabled mac drivers expose the supported
    interfaces.
 
 Tests and tooling
 -----------------
 
  - Make the YNL tool package-friendly to make it easier to deploy it
    separately from the kernel.
 
  - Increase TCP selftest coverage importing several packetdrill
    test-cases.
 
  - Regenerate the ethtool uapi header from the YNL spec,
    to ease maintenance and future development.
 
  - Add YNL support for decoding the link types used in net
    self-tests, allowing a single build to run both net and
    drivers/net.

Drivers that opt to use this API first need to identify which of the above 3
quirk combinations (for a total of 8) match what the hardware documentation
describes. Then they should wrap the packing() function, creating a new
xxx_packing() that calls it using the proper QUIRK_* one-hot bits set.
describes.
There are 3 supported usage patterns, detailed below.
packing()
^^^^^^^^^
This API function is deprecated.
The packing() function returns an int-encoded error code, which protects the
programmer against incorrect API use. The errors are not expected to occur
during runtime, therefore it is reasonable for xxx_packing() to return void
and simply swallow those errors. Optionally it can dump stack or print the
error description.
during runtime, therefore it is reasonable to wrap packing() into a custom
function which returns void and swallows those errors. Optionally it can
dump stack or print the error description.
.. code-block:: c
void my_packing(void *buf, u64 *val, int startbit, int endbit,
size_t len, enum packing_op op)
{
int err;
/* Adjust quirks accordingly */
err = packing(buf, val, startbit, endbit, len, op, QUIRK_LSW32_IS_FIRST);
if (likely(!err))
return;
if (err == -EINVAL) {
pr_err("Start bit (%d) expected to be larger than end (%d)\n",
startbit, endbit);
} else if (err == -ERANGE) {
if ((startbit - endbit + 1) > 64)
pr_err("Field %d-%d too large for 64 bits!\n",
startbit, endbit);
else
pr_err("Cannot store %llx inside bits %d-%d (would truncate)\n",
*val, startbit, endbit);
}
dump_stack();
}
pack() and unpack()
^^^^^^^^^^^^^^^^^^^
These are const-correct variants of packing(), and eliminate the last "enum
packing_op op" argument.
Calling pack(...) is equivalent, and preferred, to calling packing(..., PACK).
Calling unpack(...) is equivalent, and preferred, to calling packing(..., UNPACK).
pack_fields() and unpack_fields()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The library exposes optimized functions for the scenario where there are many
fields represented in a buffer, and it encourages consumer drivers to avoid
repetitive calls to pack() and unpack() for each field, but instead use
pack_fields() and unpack_fields(), which reduces the code footprint.
These APIs use field definitions in arrays of ``struct packed_field_u8`` or
``struct packed_field_u16``, allowing consumer drivers to minimize the size
of these arrays according to their custom requirements.
The pack_fields() and unpack_fields() API functions are actually macros which
automatically select the appropriate function at compile time, based on the
type of the fields array passed in.
An additional benefit over pack() and unpack() is that sanity checks on the
field definitions are handled at compile time with ``BUILD_BUG_ON`` rather
than only when the offending code is executed. These functions return void and
wrapping them to handle unexpected errors is not necessary.
It is recommended, but not required, that you wrap your packed buffer into a
structured type with a fixed size. This generally makes it easier for the
compiler to enforce that the correct size buffer is used.
Here is an example of how to use the fields APIs:
.. code-block:: c
/* Ordering inside the unpacked structure is flexible and can be different
* from the packed buffer. Here, it is optimized to reduce padding.
*/
struct data {
u64 field3;
u32 field4;
u16 field1;
u8 field2;
};
#define SIZE 13
typdef struct __packed { u8 buf[SIZE]; } packed_buf_t;
static const struct packed_field_u8 fields[] = {
PACKED_FIELD(100, 90, struct data, field1),
PACKED_FIELD(90, 87, struct data, field2),
PACKED_FIELD(86, 30, struct data, field3),
PACKED_FIELD(29, 0, struct data, field4),
};
void unpack_your_data(const packed_buf_t *buf, struct data *unpacked)
{
BUILD_BUG_ON(sizeof(*buf) != SIZE;
unpack_fields(buf, sizeof(*buf), unpacked, fields,
QUIRK_LITTLE_ENDIAN);
}
void pack_your_data(const struct data *unpacked, packed_buf_t *buf)
{
BUILD_BUG_ON(sizeof(*buf) != SIZE;
pack_fields(buf, sizeof(*buf), unpacked, fields,
QUIRK_LITTLE_ENDIAN);
}

================================================
This file provides device node information for the TCAN4x5x interface contains.
Required properties:
- compatible:
"ti,tcan4552", "ti,tcan4x5x"
"ti,tcan4553", "ti,tcan4x5x" or
"ti,tcan4x5x"
- reg: 0
- #address-cells: 1
- #size-cells: 0
- spi-max-frequency: Maximum frequency of the SPI bus the chip can
operate at should be less than or equal to 18 MHz.
- interrupt-parent: the phandle to the interrupt controller which provides
the interrupt.
- interrupts: interrupt specification for data-ready.
See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional
required property details.
Optional properties:
- reset-gpios: Hardwired output GPIO. If not defined then software
reset.
- device-state-gpios: Input GPIO that indicates if the device is in
a sleep state or if the device is active. Not
available with tcan4552/4553.
- device-wake-gpios: Wake up GPIO to wake up the TCAN device. Not
available with tcan4552/4553.
- wakeup-source: Leave the chip running when suspended, and configure
the RX interrupt to wake up the device.
Example:
tcan4x5x: tcan4x5x@0 {
compatible = "ti,tcan4x5x";
reg = <0>;
#address-cells = <1>;

Message RAM configuration data.
Multiple M_CAN instances can share the same Message RAM
and each element(e.g Rx FIFO or Tx Buffer and etc) number
in Message RAM is also configurable, so this property is
telling driver how the shared or private Message RAM are
used by this M_CAN controller.
The format should be as follows:
<offset sidf_elems xidf_elems rxf0_elems rxf1_elems rxb_elems txe_elems txb_elems>
The 'offset' is an address offset of the Message RAM where
the following elements start from. This is usually set to
0x0 if you're using a private Message RAM. The remain cells
are used to specify how many elements are used for each FIFO/Buffer.
M_CAN includes the following elements according to user manual:
11-bit Filter 0-128 elements / 0-128 words
29-bit Filter 0-64 elements / 0-128 words
Rx FIFO 0 0-64 elements / 0-1152 words
Rx FIFO 1 0-64 elements / 0-1152 words
Rx Buffers 0-64 elements / 0-1152 words
Tx Event FIFO 0-32 elements / 0-64 words
Tx Buffers 0-32 elements / 0-576 words
Please refer to 2.4.1 Message RAM Configuration in Bosch

Qualcomm Technologies IEEE 802.11be PCIe devices with WSI interface.
The ath12k devices (QCN9274) feature WSI support. WSI stands for
WLAN Serial Interface. It is used for the exchange of specific
control information across radios based on the doorbell mechanism.
This WSI connection is essential to exchange control information
among these devices.
The WSI interface includes TX and RX ports, which are used to connect
multiple WSI-supported devices together, forming a WSI group.
Diagram to represent one WSI connection (one WSI group) among
three devices.

- **Monitor Error Counters**:
- While some NIC drivers and PHYs provide error counters, there is no unified
set of PHY-specific counters across all hardware. Additionally, not all
PHYs provide useful information related to errors like CRC errors, frame
drops, or link flaps. Therefore, this step is dependent on the specific
hardware and driver support.
- Use `ethtool -S <interface> --all-groups` to retrieve standardized interface
statistics if the driver supports the unified interface:
- **Next Steps**: Use `ethtool -S <interface>` to check if your driver
provides useful error counters. In some cases, counters may provide
information about errors like link flaps or physical layer problems (e.g.,

Netmem Support for Network Drivers
==================================
This document outlines the requirements for network drivers to support netmem,
an abstract memory type that enables features like device memory TCP. By
supporting netmem, drivers can work with various underlying memory types
with little to no modification.
Benefits of Netmem :
* Flexibility: Netmem can be backed by different memory types (e.g., struct
page, DMA-buf), allowing drivers to support various use cases such as device
memory TCP.
* Future-proof: Drivers with netmem support are ready for upcoming
features that rely on it.
* Simplified Development: Drivers interact with a consistent API,
regardless of the underlying memory implementation.
Driver Requirements
===================
1. The driver must support page_pool.
2. The driver must support the tcp-data-split ethtool option.
3. The driver must use the page_pool netmem APIs for payload memory. The netmem
APIs currently 1-to-1 correspond with page APIs. Conversion to netmem should
be achievable by switching the page APIs to netmem APIs and tracking memory
via netmem_refs in the driver rather than struct page * :
- page_pool_alloc -> page_pool_alloc_netmem
- page_pool_get_dma_addr -> page_pool_get_dma_addr_netmem
- page_pool_put_page -> page_pool_put_netmem
Not all page APIs have netmem equivalents at the moment. If your driver
relies on a missing netmem API, feel free to add and propose to netdev@, or
reach out to the maintainers and/or almasrymina@google.com for help adding
the netmem API.
4. The driver must use the following PP_FLAGS:
- PP_FLAG_DMA_MAP: netmem is not dma-mappable by the driver. The driver
must delegate the dma mapping to the page_pool, which knows when
dma-mapping is (or is not) appropriate.
- PP_FLAG_DMA_SYNC_DEV: netmem dma addr is not necessarily dma-syncable
by the driver. The driver must delegate the dma syncing to the page_pool,
which knows when dma-syncing is (or is not) appropriate.
- PP_FLAG_ALLOW_UNREADABLE_NETMEM. The driver must specify this flag iff
tcp-data-split is enabled.
5. The driver must not assume the netmem is readable and/or backed by pages.
The netmem returned by the page_pool may be unreadable, in which case
netmem_address() will return NULL. The driver must correctly handle
unreadable netmem, i.e. don't attempt to handle its contents when
netmem_address() is NULL.
Ideally, drivers should not have to check the underlying netmem type via
helpers like netmem_is_net_iov() or convert the netmem to any of its
underlying types via netmem_to_page() or netmem_to_net_iov(). In most cases,
netmem or page_pool helpers that abstract this complexity are provided
(and more can be added).
6. The driver must use page_pool_dma_sync_netmem_for_cpu() in lieu of
dma_sync_single_range_for_cpu(). For some memory providers, dma_syncing for
CPU will be done by the page_pool, for others (particularly dmabuf memory
provider), dma syncing for CPU is the responsibility of the userspace using
dmabuf APIs. The driver must delegate the entire dma-syncing operation to
the page_pool which will do it correctly.
7. Avoid implementing driver-specific recycling on top of the page_pool. Drivers
cannot hold onto a struct page to do their own recycling as the netmem may
not be backed by a struct page. However, you may hold onto a page_pool
reference with page_pool_fragment_netmem() or page_pool_ref_netmem() for
that purpose, but be mindful that some netmem types might have longer
circulation times, such as when userspace holds a reference in zerocopy
scenarios.

TLS 1.3 Key Updates
-------------------
In TLS 1.3, KeyUpdate handshake messages signal that the sender is
updating its TX key. Any message sent after a KeyUpdate will be
encrypted using the new key. The userspace library can pass the new
key to the kernel using the TLS_TX and TLS_RX socket options, as for
the initial keys. TLS version and cipher cannot be changed.
To prevent attempting to decrypt incoming records using the wrong key,
decryption will be paused when a KeyUpdate message is received by the
kernel, until the new key has been provided using the TLS_RX socket
option. Any read occurring after the KeyUpdate has been read and
before the new key is provided will fail with EKEYEXPIRED. poll() will
not report any read events from the socket until the new key is
provided. There is no pausing on the transmit side.
Userspace should make sure that the crypto_info provided has been set
properly. In particular, the kernel will not check for key/nonce
reuse.
The number of successful and failed key updates is tracked in the
``TlsTxRekeyOk``, ``TlsRxRekeyOk``, ``TlsTxRekeyError``,

the ``Supported`` status in the MAINTAINERS file. ``Supported`` drivers must
be running all upstream driver tests and reporting the results twice a day.
Drivers which do not comply with this requirement should use the ``Maintained``
status. There is currently no difference in how ``Supported`` and ``Maintained``
drivers are treated upstream.
The exact rules a driver must follow to acquire the ``Supported`` status:
1. Must run all tests under ``drivers/net`` and ``drivers/net/hw`` targets
of Linux selftests. Running and reporting private / internal tests is
also welcome, but upstream tests are a must.
2. The minimum run frequency is once every 12 hours. Must test the
designated branch from the selected branch feed. Note that branches
are auto-constructed and exposed to intentional malicious patch posting,
so the test systems must be isolated.
3. Drivers supporting multiple generations of devices must test at
least one device from each generation. A testbed manifest (exact
format TBD) should describe the device models tested.
4. The tests must run reliably, if multiple branches are skipped or tests
are failing due to execution environment problems the ``Supported``
status will be withdrawn.
5. Test failures due to bugs either in the driver or the test itself,
or lack of support for the feature the test is targgeting are
*not* a basis for losing the ``Supported`` status.
netdev CI will maintain an official page of supported devices, listing their
recent test results.
The driver maintainer may arrange for someone else to run the test,
there is no requirement for the person listed as maintainer (or their
employer) to be responsible for running the tests. Collaboration between
vendors, hosting GH CI, other repos under linux-netdev, etc. is most welcome.
See https://github.com/linux-netdev/nipa/wiki for more information about
netdev CI. Feel free to reach out to maintainers or the list with any questions.
