Networking changes for 6.18.
Core & protocols
----------------
- Improve drop account scalability on NUMA hosts for RAW and UDP sockets
and the backlog, almost doubling the Pps capacity under DoS.
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance by
an additional 50%, even more under extreme conditions.
- Add support for PSP encryption of TCP connections; this mechanism has
some similarities with IPsec and TLS, but offers superior HW offloads
capabilities.
- Ongoing work to support Accurate ECN for TCP. AccECN allows more than
one congestion notification signal per RTT and is a building block for
Low Latency, Low Loss, and Scalable Throughput (L4S).
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath.
- Refactor skb deferral free to better scale on large multi-NUMA hosts,
this improves TCP and UDP RX performances significantly on such HW.
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds.
- Improve handling of setups with a large number of nexthop, making dump
operating scaling linearly and avoiding unneeded synchronize_rcu() on
delete.
- Improve bridge handling of VLAN FDB, storing a single entry per bridge
instead of one entry per port; this makes the dump order of magnitude
faster on large switches.
- Restore IP ID correctly for encapsulated packets at GSO segmentation
time, allowing GRO to merge packets in more scenarios.
- Improve netfilter matching performance on large sets.
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting recent
TCP autotuning changes.
- Allow bridges to redirect to a backup port when the bridge port is
administratively down.
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups.
- Add RCU safety to dst->dev, closing a lot of possible races.
- A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing
code duplication.
- Supports pulling data from an skb frag into the linear area of an XDP
buffer.
Things we sprinkled into general kernel code
--------------------------------------------
- Generate netlink documentation from YAML using an integrated
YAML parser.
Driver API
----------
- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection.
- Introduce API for fetching the DMA device for a given queue, allowing
TCP zerocopy RX on more H/W setups.
- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath.
- Add a new dedicated ethtool callback enabling drivers to provide the
number of RX rings directly, improving efficiency and clarity in RX
ring queries and RSS configuration.
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause.
- Support for DPLL phase offset exponential moving average, controlling
the average smoothing factor.

APM X-Gene SoC Ethernet nodes
|
||||
|
||||
Ethernet nodes are defined to describe on-chip ethernet interfaces in
|
||||
APM X-Gene SoC.
|
||||
|
||||
Required properties for all the ethernet interfaces:
|
||||
- compatible: Should state binding information from the following list,
|
||||
- "apm,xgene-enet": RGMII based 1G interface
|
||||
- "apm,xgene1-sgenet": SGMII based 1G interface
|
||||
- "apm,xgene1-xgenet": XFI based 10G interface
|
||||
- reg: Address and length of the register set for the device. It contains the
|
||||
information of registers in the same order as described by reg-names
|
||||
- reg-names: Should contain the register set names
|
||||
- "enet_csr": Ethernet control and status register address space
|
||||
- "ring_csr": Descriptor ring control and status register address space
|
||||
- "ring_cmd": Descriptor ring command register address space
|
||||
- interrupts: Two interrupt specifiers can be specified.
|
||||
- First is the Rx interrupt. This irq is mandatory.
|
||||
- Second is the Tx completion interrupt.
|
||||
This is supported only on SGMII based 1GbE and 10GbE interfaces.
|
||||
- channel: Ethernet to CPU, start channel (prefetch buffer) number
|
||||
- Must map to the first irq and irqs must be sequential
|
||||
- port-id: Port number (0 or 1)
|
||||
- clocks: Reference to the clock entry.
|
||||
- local-mac-address: MAC address assigned to this device
|
||||
- phy-connection-type: Interface type between ethernet device and PHY device
|
||||
|
||||
Required properties for ethernet interfaces that have external PHY:
|
||||
- phy-handle: Reference to a PHY node connected to this device
|
||||
|
||||
- mdio: Device tree subnode with the following required properties:
|
||||
- compatible: Must be "apm,xgene-mdio".
|
||||
- #address-cells: Must be <1>.
|
||||
- #size-cells: Must be <0>.
|
||||
|
||||
For the phy on the mdio bus, there must be a node with the following fields:
|
||||
- compatible: PHY identifier. Please refer ./phy.txt for the format.
|
||||
- reg: The ID number for the phy.
|
||||
|
||||
Optional properties:
|
||||
- status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok".
|
||||
- tx-delay: Delay value for RGMII bridge TX clock.
|
||||
Valid values are between 0 to 7, that maps to
|
||||
417, 717, 1020, 1321, 1611, 1913, 2215, 2514 ps
|
||||
Default value is 4, which corresponds to 1611 ps
|
||||
- rx-delay: Delay value for RGMII bridge RX clock.
|
||||
Valid values are between 0 to 7, that maps to
|
||||
273, 589, 899, 1222, 1480, 1806, 2147, 2464 ps
|
||||
Default value is 2, which corresponds to 899 ps
|
||||
- rxlos-gpios: Input gpio from SFP+ module to indicate availability of
|
||||
incoming signal.

description: |
|
||||
The Ethernet functionality in the PPE (Packet Process Engine) is comprised
|
||||
of three components, the switch core, port wrapper and Ethernet DMA.
|
||||
|
||||
The Switch core in the IPQ9574 PPE has maximum of 6 front panel ports and
|
||||
two FIFO interfaces. One of the two FIFO interfaces is used for Ethernet
|
||||
port to host CPU communication using Ethernet DMA. The other is used
|
||||
communicating to the EIP engine which is used for IPsec offload. On the
|
||||
IPQ9574, the PPE includes 6 GMAC/XGMACs that can be connected with external
|
||||
Ethernet PHY. Switch core also includes BM (Buffer Management), QM (Queue
|
||||
Management) and SCH (Scheduler) modules for supporting the packet processing.
|
||||
|
||||
The port wrapper provides connections from the 6 GMAC/XGMACS to UNIPHY (PCS)
|
||||
supporting various modes such as SGMII/QSGMII/PSGMII/USXGMII/10G-BASER. There
|
||||
are 3 UNIPHY (PCS) instances supported on the IPQ9574.
|
||||
|
||||
Ethernet DMA is used to transmit and receive packets between the six Ethernet
|
||||
ports and ARM host CPU.
|
||||
|
||||
The follow diagram shows the PPE hardware block along with its connectivity
|
||||
to the external hardware blocks such clock hardware blocks (CMNPLL, GCC,
|
||||
NSS clock controller) and Ethernet PCS/PHY blocks. For depicting the PHY
|
||||
connectivity, one 4x1 Gbps PHY (QCA8075) and two 10 GBps PHYs are used as an
|
||||
example.

8.3. Painfully Slow Or No Failed Link Detection By Miimon
|
||||
---------------------------------------------------------
|
||||
|
||||
By default, bonding enables the use_carrier option, which
|
||||
instructs bonding to trust the driver to maintain carrier state.
|
||||
|
||||
As discussed in the options section, above, some drivers do
|
||||
not support the netif_carrier_on/_off link state tracking system.
|
||||
With use_carrier enabled, bonding will always see these links as up,
|
||||
regardless of their actual state.
|
||||
|
||||
Additionally, other drivers do support netif_carrier, but do
|
||||
not maintain it in real time, e.g., only polling the link state at
|
||||
some fixed interval. In this case, miimon will detect failures, but
|
||||
only after some long period of time has expired. If it appears that
|
||||
miimon is very slow in detecting link failures, try specifying
|
||||
use_carrier=0 to see if that improves the failure detection time. If
|
||||
it does, then it may be that the driver checks the carrier state at a
|
||||
fixed interval, but does not cache the MII register values (so the
|
||||
use_carrier=0 method of querying the registers directly works). If
|
||||
use_carrier=0 does not improve the failover, then the driver may cache
|
||||
the registers, or the problem may be elsewhere.
|
||||
|
||||
Also, remember that miimon only checks for the device's
|
||||
carrier state. It has no way to determine the state of devices on or
|
||||
beyond other ports of a switch, or if a switch is refusing to pass
|
||||
traffic while still maintaining carrier on.

PPE Overview
|
||||
============
|
||||
|
||||
IPQ (Qualcomm Internet Processor) SoC (System-on-Chip) series is Qualcomm's series of
|
||||
networking SoC for Wi-Fi access points. The PPE (Packet Process Engine) is the Ethernet
|
||||
packet process engine in the IPQ SoC.
|
||||
|
||||
Below is a simplified hardware diagram of IPQ9574 SoC which includes the PPE engine and
|
||||
other blocks which are in the SoC but outside the PPE engine. These blocks work together
|
||||
to enable the Ethernet for the IPQ SoC::

|

The CMN (Common) PLL, NSSCC (Networking Sub System Clock Controller) and GCC (Global
|
||||
Clock Controller) blocks are in the SoC and act as clock providers.
|
||||
|
||||
The UNIPHY block is in the SoC and provides the PCS (Physical Coding Sublayer) and
|
||||
XPCS (10-Gigabit Physical Coding Sublayer) functions to support different interface
|
||||
modes between the PPE MAC and the external PHY.
|
||||
|
||||
This documentation focuses on the descriptions of PPE engine and the PPE driver.
|
||||
|
||||
The Ethernet functionality in the PPE (Packet Process Engine) is comprised of three
|
||||
components: the switch core, port wrapper and Ethernet DMA.
|
||||
|
||||
The Switch core in the IPQ9574 PPE has maximum of 6 front panel ports and two FIFO
|
||||
interfaces. One of the two FIFO interfaces is used for Ethernet port to host CPU
|
||||
communication using Ethernet DMA. The other one is used to communicate to the EIP
|
||||
engine which is used for IPsec offload. On the IPQ9574, the PPE includes 6 GMAC/XGMACs
|
||||
that can be connected with external Ethernet PHY. Switch core also includes BM (Buffer
|
||||
Management), QM (Queue Management) and SCH (Scheduler) modules for supporting the
|
||||
packet processing.
|
||||
|
||||
The port wrapper provides connections from the 6 GMAC/XGMACS to UNIPHY (PCS) supporting
|
||||
various modes such as SGMII/QSGMII/PSGMII/USXGMII/10G-BASER. There are 3 UNIPHY (PCS)
|
||||
instances supported on the IPQ9574.
|
||||
|
||||
Ethernet DMA is used to transmit and receive packets between the Ethernet subsystem
|
||||
and ARM host CPU.
|
||||
|
||||
The following lists the main blocks in the PPE engine which will be driven by this
|
||||
PPE driver:
|
||||
|
||||
- BM
|
||||
BM is the hardware buffer manager for the PPE switch ports.
|
||||
- QM
|
||||
Queue Manager for managing the egress hardware queues of the PPE switch ports.
|
||||
- SCH
|
||||
The scheduler which manages the hardware traffic scheduling for the PPE switch ports.
|
||||
- L2
|
||||
The L2 block performs the packet bridging in the switch core. The bridge domain is
|
||||
represented by the VSI (Virtual Switch Instance) domain in PPE. FDB learning can be
|
||||
enabled based on the VSI domain and bridge forwarding occurs within the VSI domain.
|
||||
- MAC
|
||||
The PPE in the IPQ9574 supports up to six MACs (MAC0 to MAC5) which are corresponding
|
||||
to six switch ports (port1 to port6). The MAC block is connected with external PHY
|
||||
through the UNIPHY PCS block. Each MAC block includes the GMAC and XGMAC blocks and
|
||||
the switch port can select to use GMAC or XMAC through a MUX selection according to
|
||||
the external PHY's capability.
|
||||
- EDMA (Ethernet DMA)
|
||||
The Ethernet DMA is used to transmit and receive Ethernet packets between the PPE
|
||||
ports and the ARM cores.
|
||||
|
||||
The received packet on a PPE MAC port can be forwarded to another PPE MAC port. It can
|
||||
be also forwarded to internal switch port0 so that the packet can be delivered to the
|
||||
ARM cores using the Ethernet DMA (EDMA) engine. The Ethernet DMA driver will deliver the
|
||||
packet to the corresponding 'netdevice' interface.
|
||||
|
||||
The software instantiations of the PPE MAC (netdevice), PCS and external PHYs interact
|
||||
with the Linux PHYLINK framework to manage the connectivity between the PPE ports and
|
||||
the connected PHYs, and the port link states. This is also illustrated in above diagram.
|
||||
|
||||
|
||||
PPE Driver Overview
|
||||
===================
|
||||
PPE driver is Ethernet driver for the Qualcomm IPQ SoC. It is a single platform driver
|
||||
which includes the PPE part and Ethernet DMA part. The PPE part initializes and drives the
|
||||
various blocks in PPE switch core such as BM/QM/L2 blocks and the PPE MACs. The EDMA part
|
||||
drives the Ethernet DMA for packet transfer between PPE ports and ARM cores, and enables
|
||||
the netdevice driver for the PPE ports.
|
||||
|
||||
The PPE driver files in drivers/net/ethernet/qualcomm/ppe/ are listed as below:
|
||||
|
||||
- Makefile
|
||||
- ppe.c
|
||||
- ppe.h
|
||||
- ppe_config.c
|
||||
- ppe_config.h
|
||||
- ppe_debugfs.c
|
||||
- ppe_debugfs.h
|
||||
- ppe_regs.h
|
||||
|
||||
The ppe.c file contains the main PPE platform driver and undertakes the initialization of
|
||||
PPE switch core blocks such as QM, BM and L2. The configuration APIs for these hardware
|
||||
blocks are provided in the ppe_config.c file.
|
||||
|
||||
The ppe.h defines the PPE device data structure which will be used by PPE driver functions.
|
||||
|
||||
The ppe_debugfs.c enables the PPE statistics counters such as PPE port Rx and Tx counters,
|
||||
CPU code counters and queue counters.

||||

||||
|
||||
PPE Driver Supported SoCs
|
||||
=========================
|
||||
|
||||
The PPE driver supports the following IPQ SoC:
|
||||
|
||||
- IPQ9574
|
||||
|
||||
|
||||
Enabling the Driver
|
||||
===================
|
||||
|
||||
The driver is located in the menu structure at::
|
||||
|
||||

|
||||
-> Network device support (NETDEVICES [=y])
|
||||
-> Ethernet driver support
|
||||
-> Qualcomm devices
|
||||
-> Qualcomm Technologies, Inc. PPE Ethernet support
|
||||
|
||||
If the driver is built as a module, the module will be called qcom-ppe.
|
||||
|
||||
The PPE driver functionally depends on the CMN PLL and NSSCC clock controller drivers.
|
||||
Please make sure the dependent modules are installed before installing the PPE driver
|
||||
module.

============

The ``zl3073x`` driver implements support for flash update using the

``devlink-flash`` interface. It supports updating the device flash using a

combined flash image ("bundle") that contains multiple components (firmware

parts and configurations).
|

During the flash procedure, the standard firmware interface is not available,

so the driver unregisters all DPLLs and associated pins, and re-registers them

once the flash procedure is complete.

PSP Security Protocol
|
||||
=====================
|
||||
|
||||
Protocol
|
||||
========
|
||||
|
||||
PSP Security Protocol (PSP) was defined at Google and published in:
|
||||
|
||||
https://raw.githubusercontent.com/google/psp/main/doc/PSP_Arch_Spec.pdf
|
||||
|
||||
This section briefly covers protocol aspects crucial for understanding
|
||||
the kernel API. Refer to the protocol specification for further details.
|
||||
|
||||
Note that the kernel implementation and documentation uses the term
|
||||
"device key" in place of "master key", it is both less confusing
|
||||
to an average developer and is less likely to run afoul any naming
|
||||
guidelines.
|
||||
|
||||
Derived Rx keys
|
||||
---------------
|
||||
|
||||
PSP borrows some terms and mechanisms from IPsec. PSP was designed
|
||||
with HW offloads in mind. The key feature of PSP is that Rx keys for every
|
||||
connection do not have to be stored by the receiver but can be derived
|
||||
from device key and information present in packet headers.
|
||||
This makes it possible to implement receivers which require a constant
|
||||
amount of memory regardless of the number of connections (``O(1)`` scaling).
|
||||
|
||||
Tx keys have to be stored like with any other protocol, but Tx is much
|
||||
less latency sensitive than Rx, and delays in fetching keys from slow
|
||||
memory is less likely to cause packet drops. Preferably, the Tx keys
|
||||
should be provided with the packet (e.g. as part of the descriptors).
|
||||
|
||||
Key rotation
|
||||
------------
|
||||
|
||||
The device key known only to the receiver is fundamental to the design.
|
||||
Per specification this state cannot be directly accessible (it must be
|
||||
impossible to read it out of the hardware of the receiver NIC).
|
||||
Moreover, it has to be "rotated" periodically (usually daily). Rotation
|
||||
means that new device key gets generated (by a random number generator
|
||||
of the device), and used for all new connections. To avoid disrupting
|
||||
old connections the old device key remains in the NIC. A phase bit
|
||||
carried in the packet headers indicates which generation of device key
|
||||
the packet has been encrypted with.
|
||||
|
||||
User facing API
|
||||
===============
|
||||
|
||||
PSP is designed primarily for hardware offloads. There is currently
|
||||
no software fallback for systems which do not have PSP capable NICs.
|
||||
There is also no standard (or otherwise defined) way of establishing
|
||||
a PSP-secured connection or exchanging the symmetric keys.
|
||||
|
||||
The expectation is that higher layer protocols will take care of
|
||||
protocol and key negotiation. For example one may use TLS key exchange,
|
||||
announce the PSP capability, and switch to PSP if both endpoints
|
||||
are PSP-capable.
|
||||
|
||||
All configuration of PSP is performed via the PSP netlink family.
|
||||
|
||||
Device discovery
|
||||
----------------
|
||||
|
||||
The PSP netlink family defines operations to retrieve information
|
||||
about the PSP devices available on the system, configure them and
|
||||
access PSP related statistics.
|
||||
|
||||
Securing a connection
|
||||
---------------------
|
||||
|
||||
PSP encryption is currently only supported for TCP connections.
|
||||
Rx and Tx keys are allocated separately. First the ``rx-assoc``
|
||||
Netlink command needs to be issued, specifying a target TCP socket.
|
||||
Kernel will allocate a new PSP Rx key from the NIC and associate it
|
||||
with given socket. At this stage socket will accept both PSP-secured
|
||||
and plain text TCP packets.
|
||||
|
||||
Tx keys are installed using the ``tx-assoc`` Netlink command.
|
||||
Once the Tx keys are installed, all data read from the socket will
|
||||
be PSP-secured. In other words act of installing Tx keys has a secondary
|
||||
effect on the Rx direction.
|
||||
|
||||
There is an intermediate period after ``tx-assoc`` successfully
|
||||
returns and before the TCP socket encounters it's first PSP
|
||||
authenticated packet, where the TCP stack will allow certain nondata
|
||||
packets, i.e. ACKs, FINs, and RSTs, to enter TCP receive processing
|
||||
even if not PSP authenticated. During the ``tx-assoc`` call, the TCP
|
||||
socket's ``rcv_nxt`` field is recorded. At this point, ACKs and RSTs
|
||||
will be accepted with any sequence number, while FINs will only be
|
||||
accepted at the latched value of ``rcv_nxt``. Once the TCP stack
|
||||
encounters the first TCP packet containing PSP authenticated data, the
|
||||
other end of the connection must have executed the ``tx-assoc``
|
||||
command, so any TCP packet, including those without data, will be
|
||||
dropped before receive processing if it is not successfully
|
||||
authenticated. This is summarized in the table below. The
|
||||
aforementioned state of rejecting all non-PSP packets is labeled "PSP
|
||||
Full".
|
||||
|
||||
+----------------+------------+------------+-------------+-------------+
|
||||
| Event | Normal TCP | Rx PSP | Tx PSP | PSP Full |
|
||||
+================+============+============+=============+=============+
|
||||
| Rx plain | accept | accept | drop | drop |
|
||||
| (data) | | | | |
|
||||
+----------------+------------+------------+-------------+-------------+
|
||||
| Rx plain | accept | accept | accept | drop |
|
||||
| (ACK|FIN|RST) | | | | |
|
||||
+----------------+------------+------------+-------------+-------------+
|
||||

|
||||
+----------------+------------+------------+-------------+-------------+
|
||||
| Rx PSP (bad | drop | drop | drop | drop |
|
||||
| crypt, !=SPI) | | | | |
|
||||
+----------------+------------+------------+-------------+-------------+
|
||||
| Tx | plain text | plain text | encrypted | encrypted |
|
||||
| | | | (excl. rtx) | (excl. rtx) |
|
||||
+----------------+------------+------------+-------------+-------------+
|
||||
|
||||
To ensure that any data read from the socket after the ``tx-assoc``
|
||||
call returns success has been authenticated, the kernel will scan the
|
||||
receive and ofo queues of the socket at ``tx-assoc`` time. If any
|
||||
enqueued packet was received in clear text, the Tx association will
|
||||
fail, and the application should retry installing the Tx key after
|
||||
draining the socket (this should not be necessary if both endpoints
|
||||
are well behaved).
|
||||
|
||||
Because TCP sequence numbers are not integrity protected prior to
|
||||
upgrading to PSP, it is possible that a MITM could offset sequence
|
||||
numbers in a way that deletes a prefix of the PSP protected part of
|
||||
the TCP stream. If userspace cares to mitigate this type of attack, a
|
||||
special "start of PSP" message should be exchanged after ``tx-assoc``.
|
||||
|
||||
Rotation notifications
|
||||
----------------------
|
||||
|
||||
The rotations of device key happen asynchronously and are usually
|
||||
performed by management daemons, not under application control.
|
||||
The PSP netlink family will generate a notification whenever keys
|
||||
are rotated. The applications are expected to re-establish connections
|
||||
before keys are rotated again.
|
||||
|
||||
Kernel implementation
|
||||
=====================
|
||||
|
||||
Driver notes
|
||||
------------
|
||||
|
||||
Drivers are expected to start with no PSP enabled (``psp-versions-ena``
|
||||
in ``dev-get`` set to ``0``) whenever possible. The user space should
|
||||
not depend on this behavior, as future extension may necessitate creation
|
||||
of devices with PSP already enabled, nonetheless drivers should not enable
|
||||
PSP by default. Enabling PSP should be the responsibility of the system
|
||||
component which also takes care of key rotation.
|
||||
|
||||
Note that ``psp-versions-ena`` is expected to be used only for enabling
|
||||
receive processing. The device is not expected to reject transmit requests
|
||||
after ``psp-versions-ena`` has been disabled. User may also disable
|
||||
``psp-versions-ena`` while there are active associations, which will
|
||||
break all PSP Rx processing.
|
||||
|
||||
Drivers are expected to ensure that a device key is usable and secure
|
||||
upon init, without explicit key rotation by the user space. It must be
|
||||
possible to allocate working keys, and that no duplicate keys must be
|
||||
generated. If the device allows the host to request the key for an
|
||||
arbitrary SPI - driver should discard both device keys (rotate the
|
||||
device key twice), to avoid potentially using a SPI+key which previous
|
||||
OS instance already had access to.
|
||||
|
||||
Drivers must use ``psp_skb_get_assoc_rcu()`` to check if PSP Tx offload
|
||||
was requested for given skb. On Rx drivers should allocate and populate
|
||||
the ``SKB_EXT_PSP`` skb extension, and set the skb->decrypted bit to 1.
|
||||
|
||||
Kernel implementation notes
|
||||
---------------------------
|
||||
|
||||
PSP implementation follows the TLS offload more closely than the IPsec
|
||||
offload, with per-socket state, and the use of skb->decrypted to prevent
|
||||
clear text leaks.
|
||||
|
||||
PSP device is separate from netdev, to make it possible to "delegate"
|
||||
PSP offload capabilities to software devices (e.g. ``veth``).
