Networking changes for 6.8.
Core & protocols
----------------
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up
build time warnings to safeguard against future header changes.
This improves TCP performances with many concurrent connections
up to 40%.
- Add page-pool netlink-based introspection, exposing the
memory usage and recycling stats. This helps indentify
bad PP users and possible leaks.
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set.
This lowers the time taken by connect() for hosts having
many active connections to the same destination.
- Refactor the TCP bind conflict code, shrinking related socket
structs.
- Refactor TCP SYN-Cookie handling, as a preparation step to
allow arbitrary SYN-Cookie processing via eBPF.
- Tune optmem_max for 0-copy usage, increasing the default value
to 128KB and namespecifying it.
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations.
- Reduce extension header parsing overhead at GRO time.
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries.
- Reorder nftables struct members, to keep data accessed by the
datapath first.
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer.
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex).
- More data-race annotations.
- Extend the diag interface to dump TCP bound-only sockets.
- Conditional notification of events for TC qdisc class and actions.
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID.
- Implement SMCv2.1 virtual ISM device support.
- Add support for Batman-avd mulicast packet type.
BPF
---
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers. It
improves the verifier "instructions processed" metric from single
digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload.
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y.
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques.
- Support uid/gid options when mounting bpffs.
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is identified
by its id.
- Extend verifier to allow bpf_refcount_acquire() of a map value field
obtained via direct load which is a use-case needed in sched_ext.
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter.
- Support for VLAN tag in XDP hints.
- Remove deprecated bpfilter kernel leftovers given the project
is developed in user-space (https://github.com/facebook/bpfilter).
Misc
----
- Support for parellel TC self-tests execution.
- Increase MPTCP self-tests coverage.
- Updated the bridge documentation, including several so-far
undocumented features.
- Convert all the net self-tests to run in unique netns, to
avoid random failures due to conflict and allow concurrent
runs.
- Add TCP-AO self-tests.
- Add kunit tests for both cfg80211 and mac80211.
- Autogenerate Netlink families documentation from YAML spec.
- Add yml-gen support for fixed headers and recursive nests, the
tool can now generate user-space code for all genetlink families
for which we have specs.
- A bunch of additional module descriptions fixes.
- Catch incorrect freeing of pages belonging to a page pool.
Driver API
----------
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust.
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship.
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances.
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host.
- Add support for ethtool symmetric-xor RSS hash.
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform.
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute.
- Convert older drivers to platform remove callback returning void.
- Add support for PHY package MMD read/write.

BPF filesystem kfuncs
|

=====================
|

|

BPF LSM programs need to access filesystem data from LSM hooks. The following
|
||||
BPF kfuncs can be used to get these data.
|
||||
|
||||
* ``bpf_get_file_xattr()``
|
||||
|
||||
* ``bpf_get_fsverity_digest()``
|
||||
|
||||
To avoid recursions, these kfuncs follow the following rules:
|
||||
|
||||
1. These kfuncs are only permitted from BPF LSM function.
|
||||
2. These kfuncs should not call into other LSM hooks, i.e. security_*(). For
|
||||
example, ``bpf_get_file_xattr()`` does not use ``vfs_getxattr()``, because
|
||||
the latter calls LSM hook ``security_inode_getxattr``.

The Marvell MV88E6060 switch has been produced and sold by Marvell
|
||||
since at least 2008. The switch has one pin ADDR4 that controls the
|
||||
MDIO address of the switch to be 0x10 or 0x00, and on the MDIO bus
|
||||
connected to the switch, the PHYs inside the switch appear as
|
||||
independent devices on address 0x00-0x04 or 0x10-0x14, so in difference
|
||||
from many other DSA switches this switch does not have an internal
|
||||
MDIO bus for the PHY devices.

WARNING: This binding is currently unstable. Do not program it into a
|
||||
FLASH never to be changed again. Once this binding is stable, this

Marvell Switches are MDIO devices. The following properties should be
|
||||
placed as a child node of an mdio device.
|
||||
|
||||
The properties described here are those specific to Marvell devices.
|
||||
Additional required and optional properties can be found in dsa.txt.
|
||||
|
||||
The compatibility string is used only to find an identification register,
|
||||
which is at a different MDIO base address in different switch families.
|
||||
- "marvell,mv88e6085" : Switch has base address 0x10. Use with models:
|
||||
6085, 6095, 6097, 6123, 6131, 6141, 6161, 6165,
|

|
||||
6341, 6350, 6351, 6352
|
||||
- "marvell,mv88e6190" : Switch has base address 0x00. Use with models:
|
||||
6190, 6190X, 6191, 6290, 6361, 6390, 6390X
|
||||
- "marvell,mv88e6250" : Switch has base address 0x08 or 0x18. Use with model:
|
||||
6220, 6250
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be one of "marvell,mv88e6085",
|
||||
"marvell,mv88e6190" or "marvell,mv88e6250" as
|
||||
indicated above
|
||||
- reg : Address on the MII bus for the switch.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- reset-gpios : Should be a gpio specifier for a reset line
|
||||
- interrupts : Interrupt from the switch
|
||||
- interrupt-controller : Indicates the switch is itself an interrupt
|
||||
controller. This is used for the PHY interrupts.
|
||||
#interrupt-cells = <2> : Controller uses two cells, number and flag
|
||||
- eeprom-length : Set to the length of an EEPROM connected to the

work.
|

This can be done and is implemented by OEM in 3 different way:

- Attached SPI flash directly to the PHY with the firmware. The PHY

will self load the firmware in the presence of this configuration.
|
||||
- Read from a dedicated partition on system NAND declared in an

NVMEM cell, and loaded to the PHY using its mailbox interface.
|

- Manually provided firmware loaded from a file in the filesystem.

Ethernet Bridging
|
||||
=================
|
||||
|
||||
In order to use the Ethernet bridging functionality, you'll need the
|
||||
userspace tools.
|
||||
Introduction
|
||||
============
|
||||
|
||||
Documentation for Linux bridging is on:
|
||||
https://wiki.linuxfoundation.org/networking/bridge
|
||||
The IEEE 802.1Q-2022 (Bridges and Bridged Networks) standard defines the
|
||||
operation of bridges in computer networks. A bridge, in the context of this
|
||||
standard, is a device that connects two or more network segments and operates
|
||||
at the data link layer (Layer 2) of the OSI (Open Systems Interconnection)
|
||||
model. The purpose of a bridge is to filter and forward frames between
|
||||
different segments based on the destination MAC (Media Access Control) address.
|
||||
|
||||
The bridge-utilities are maintained at:
|
||||
git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/bridge-utils.git
|
||||
Bridge kAPI
|
||||
===========
|
||||
|
||||
Additionally, the iproute2 utilities can be used to configure
|
||||
bridge devices.
|
||||
Here are some core structures of bridge code. Note that the kAPI is *unstable*,
|
||||
and can be changed at any time.
|
||||
|
||||
If you still have questions, don't hesitate to post to the mailing list
|
||||
(more info https://lists.linux-foundation.org/mailman/listinfo/bridge).
|
||||
.. kernel-doc:: net/bridge/br_private.h
|
||||
:identifiers: net_bridge_vlan
|
||||
|
||||
Bridge uAPI
|
||||
===========
|
||||
|
||||
Modern Linux bridge uAPI is accessed via Netlink interface. You can find
|
||||
below files where the bridge and bridge port netlink attributes are defined.
|
||||
|
||||
Bridge netlink attributes
|
||||

||||

||||

||||

|
||||
|
||||

|
||||
Bridge sysfs
|
||||
------------
|
||||
|
||||
The sysfs interface is deprecated and should not be extended if new
|
||||
options are added.
|
||||
|
||||
STP
|
||||
===
|
||||
|
||||
The STP (Spanning Tree Protocol) implementation in the Linux bridge driver
|
||||
is a critical feature that helps prevent loops and broadcast storms in
|
||||
Ethernet networks by identifying and disabling redundant links. In a Linux
|
||||
bridge context, STP is crucial for network stability and availability.
|
||||
|
||||
STP is a Layer 2 protocol that operates at the Data Link Layer of the OSI
|
||||
model. It was originally developed as IEEE 802.1D and has since evolved into
|
||||
multiple versions, including Rapid Spanning Tree Protocol (RSTP) and
|
||||
`Multiple Spanning Tree Protocol (MSTP)
|
||||
<https://lore.kernel.org/netdev/20220316150857.2442916-1-tobias@waldekranz.com/>`_.
|
||||
|
||||
The 802.1D-2004 removed the original Spanning Tree Protocol, instead
|
||||
incorporating the Rapid Spanning Tree Protocol (RSTP). By 2014, all the
|
||||
functionality defined by IEEE 802.1D has been incorporated into either
|
||||
IEEE 802.1Q (Bridges and Bridged Networks) or IEEE 802.1AC (MAC Service
|
||||
Definition). 802.1D has been officially withdrawn in 2022.
|
||||
|
||||
Bridge Ports and STP States
|
||||
---------------------------
|
||||
|
||||
In the context of STP, bridge ports can be in one of the following states:
|
||||
* Blocking: The port is disabled for data traffic and only listens for
|
||||
BPDUs (Bridge Protocol Data Units) from other devices to determine the
|
||||
network topology.
|
||||
* Listening: The port begins to participate in the STP process and listens
|
||||
for BPDUs.
|
||||
* Learning: The port continues to listen for BPDUs and begins to learn MAC
|
||||
addresses from incoming frames but does not forward data frames.
|
||||
* Forwarding: The port is fully operational and forwards both BPDUs and
|
||||
data frames.
|
||||
* Disabled: The port is administratively disabled and does not participate
|
||||
in the STP process. The data frames forwarding are also disabled.
|
||||
|
||||
Root Bridge and Convergence
|
||||
---------------------------
|
||||
|
||||
In the context of networking and Ethernet bridging in Linux, the root bridge
|
||||
is a designated switch in a bridged network that serves as a reference point
|
||||
for the spanning tree algorithm to create a loop-free topology.
|
||||
|
||||
Here's how the STP works and root bridge is chosen:
|
||||
1. Bridge Priority: Each bridge running a spanning tree protocol, has a
|
||||
configurable Bridge Priority value. The lower the value, the higher the
|
||||
priority. By default, the Bridge Priority is set to a standard value
|
||||
(e.g., 32768).
|
||||
2. Bridge ID: The Bridge ID is composed of two components: Bridge Priority
|
||||
and the MAC address of the bridge. It uniquely identifies each bridge
|
||||
in the network. The Bridge ID is used to compare the priorities of
|
||||
different bridges.
|
||||
3. Bridge Election: When the network starts, all bridges initially assume
|
||||
that they are the root bridge. They start advertising Bridge Protocol
|
||||
Data Units (BPDU) to their neighbors, containing their Bridge ID and
|
||||
other information.
|
||||
4. BPDU Comparison: Bridges exchange BPDUs to determine the root bridge.
|
||||
Each bridge examines the received BPDUs, including the Bridge Priority
|
||||
and Bridge ID, to determine if it should adjust its own priorities.
|
||||
The bridge with the lowest Bridge ID will become the root bridge.
|
||||
5. Root Bridge Announcement: Once the root bridge is determined, it sends
|
||||
BPDUs with information about the root bridge to all other bridges in the
|
||||
network. This information is used by other bridges to calculate the
|
||||
shortest path to the root bridge and, in doing so, create a loop-free
|
||||
topology.
|
||||
6. Forwarding Ports: After the root bridge is selected and the spanning tree
|
||||
topology is established, each bridge determines which of its ports should
|
||||
be in the forwarding state (used for data traffic) and which should be in
|
||||
the blocking state (used to prevent loops). The root bridge's ports are
|
||||
all in the forwarding state. while other bridges have some ports in the
|
||||
blocking state to avoid loops.
|
||||
7. Root Ports: After the root bridge is selected and the spanning tree
|
||||
topology is established, each non-root bridge processes incoming
|
||||
BPDUs and determines which of its ports provides the shortest path to the
|
||||
root bridge based on the information in the received BPDUs. This port is
|
||||
designated as the root port. And it is in the Forwarding state, allowing
|
||||
it to actively forward network traffic.
|
||||
8. Designated ports: A designated port is the port through which the non-root
|
||||
bridge will forward traffic towards the designated segment. Designated ports
|
||||
are placed in the Forwarding state. All other ports on the non-root
|
||||
bridge that are not designated for specific segments are placed in the
|
||||
Blocking state to prevent network loops.
|
||||
|
||||
STP ensures network convergence by calculating the shortest path and disabling
|
||||
redundant links. When network topology changes occur (e.g., a link failure),
|
||||
STP recalculates the network topology to restore connectivity while avoiding loops.
|
||||
|
||||
Proper configuration of STP parameters, such as the bridge priority, can
|
||||
influence network performance, path selection and which bridge becomes the
|
||||
Root Bridge.
|
||||
|
||||
User space STP helper
|
||||
---------------------
|
||||
|
||||
The user space STP helper *bridge-stp* is a program to control whether to use
|
||||
user mode spanning tree. The ``/sbin/bridge-stp <bridge> <start|stop>`` is
|
||||
called by the kernel when STP is enabled/disabled on a bridge
|
||||
(via ``brctl stp <bridge> <on|off>`` or ``ip link set <bridge> type bridge
|
||||
stp_state <0|1>``). The kernel enables user_stp mode if that command returns
|
||||
0, or enables kernel_stp mode if that command returns any other value.
|
||||
|
||||
VLAN
|
||||
====
|
||||
|
||||
A LAN (Local Area Network) is a network that covers a small geographic area,
|
||||
typically within a single building or a campus. LANs are used to connect
|
||||
computers, servers, printers, and other networked devices within a localized
|
||||
area. LANs can be wired (using Ethernet cables) or wireless (using Wi-Fi).
|
||||
|
||||
A VLAN (Virtual Local Area Network) is a logical segmentation of a physical
|
||||
network into multiple isolated broadcast domains. VLANs are used to divide
|
||||
a single physical LAN into multiple virtual LANs, allowing different groups of
|
||||
devices to communicate as if they were on separate physical networks.
|
||||
|
||||
Typically there are two VLAN implementations, IEEE 802.1Q and IEEE 802.1ad
|
||||
(also known as QinQ). IEEE 802.1Q is a standard for VLAN tagging in Ethernet
|
||||
networks. It allows network administrators to create logical VLANs on a
|
||||
physical network and tag Ethernet frames with VLAN information, which is
|
||||
called *VLAN-tagged frames*. IEEE 802.1ad, commonly known as QinQ or Double
|
||||
VLAN, is an extension of the IEEE 802.1Q standard. QinQ allows for the
|
||||
stacking of multiple VLAN tags within a single Ethernet frame. The Linux
|
||||
bridge supports both the IEEE 802.1Q and `802.1AD
|
||||
<https://lore.kernel.org/netdev/1402401565-15423-1-git-send-email-makita.toshiaki@lab.ntt.co.jp/>`_
|
||||
protocol for VLAN tagging.
|
||||
|
||||
`VLAN filtering <https://lore.kernel.org/netdev/1360792820-14116-1-git-send-email-vyasevic@redhat.com/>`_
|
||||
on a bridge is disabled by default. After enabling VLAN filtering on a bridge,
|
||||
it will start forwarding frames to appropriate destinations based on their
|
||||
destination MAC address and VLAN tag (both must match).
|
||||
|
||||
Multicast
|
||||
=========
|
||||
|
||||
The Linux bridge driver has multicast support allowing it to process Internet
|
||||
Group Management Protocol (IGMP) or Multicast Listener Discovery (MLD)
|
||||
messages, and to efficiently forward multicast data packets. The bridge
|
||||
driver supports IGMPv2/IGMPv3 and MLDv1/MLDv2.
|
||||
|
||||
Multicast snooping
|
||||
------------------
|
||||
|
||||
Multicast snooping is a networking technology that allows network switches
|
||||
to intelligently manage multicast traffic within a local area network (LAN).
|
||||
|
||||
The switch maintains a multicast group table, which records the association
|
||||
between multicast group addresses and the ports where hosts have joined these
|
||||
groups. The group table is dynamically updated based on the IGMP/MLD messages
|
||||
received. With the multicast group information gathered through snooping, the
|
||||
switch optimizes the forwarding of multicast traffic. Instead of blindly
|
||||
broadcasting the multicast traffic to all ports, it sends the multicast
|
||||
traffic based on the destination MAC address only to ports which have
|
||||
subscribed the respective destination multicast group.
|
||||
|
||||
When created, the Linux bridge devices have multicast snooping enabled by
|
||||
default. It maintains a Multicast forwarding database (MDB) which keeps track
|
||||
of port and group relationships.
|
||||
|
||||
IGMPv3/MLDv2 EHT support
|
||||
------------------------
|
||||
|
||||
The Linux bridge supports IGMPv3/MLDv2 EHT (Explicit Host Tracking), which
|
||||
was added by `474ddb37fa3a ("net: bridge: multicast: add EHT allow/block handling")
|
||||
<https://lore.kernel.org/netdev/20210120145203.1109140-1-razor@blackwall.org/>`_
|
||||
|
||||
The explicit host tracking enables the device to keep track of each
|
||||
individual host that is joined to a particular group or channel. The main
|
||||
benefit of the explicit host tracking in IGMP is to allow minimal leave
|
||||
latencies when a host leaves a multicast group or channel.
|
||||
|
||||
The length of time between a host wanting to leave and a device stopping
|
||||
traffic forwarding is called the IGMP leave latency. A device configured
|
||||
with IGMPv3 or MLDv2 and explicit tracking can immediately stop forwarding
|
||||
traffic if the last host to request to receive traffic from the device
|
||||
indicates that it no longer wants to receive traffic. The leave latency
|
||||
is thus bound only by the packet transmission latencies in the multiaccess
|
||||
network and the processing time in the device.
|
||||
|
||||
Other multicast features
|
||||
------------------------
|
||||
|
||||
The Linux bridge also supports `per-VLAN multicast snooping
|
||||
<https://lore.kernel.org/netdev/20210719170637.435541-1-razor@blackwall.org/>`_,
|
||||
which is disabled by default but can be enabled. And `Multicast Router Discovery
|
||||
<https://lore.kernel.org/netdev/20190121062628.2710-1-linus.luessing@c0d3.blue/>`_,
|
||||
which help identify the location of multicast routers.
|
||||
|
||||
Switchdev
|
||||
=========
|
||||
|
||||
Linux Bridge Switchdev is a feature in the Linux kernel that extends the
|
||||
capabilities of the traditional Linux bridge to work more efficiently with
|
||||
hardware switches that support switchdev. With Linux Bridge Switchdev, certain
|
||||
networking functions like forwarding, filtering, and learning of Ethernet
|
||||
frames can be offloaded to a hardware switch. This offloading reduces the
|
||||
burden on the Linux kernel and CPU, leading to improved network performance
|
||||
and lower latency.
|
||||
|
||||
To use Linux Bridge Switchdev, you need hardware switches that support the
|
||||
switchdev interface. This means that the switch hardware needs to have the
|
||||
necessary drivers and functionality to work in conjunction with the Linux
|
||||
kernel.
|
||||
|
||||
Please see the :ref:`switchdev` document for more details.
|
||||
|
||||
Netfilter
|
||||
=========
|
||||
|
||||
The bridge netfilter module is a legacy feature that allows to filter bridged
|
||||
packets with iptables and ip6tables. Its use is discouraged. Users should
|
||||
consider using nftables for packet filtering.
|
||||
|
||||
The older ebtables tool is more feature-limited compared to nftables, but
|
||||
just like nftables it doesn't need this module either to function.
|
||||
|
||||
The br_netfilter module intercepts packets entering the bridge, performs
|
||||
minimal sanity tests on ipv4 and ipv6 packets and then pretends that
|
||||
these packets are being routed, not bridged. br_netfilter then calls
|
||||
the ip and ipv6 netfilter hooks from the bridge layer, i.e. ip(6)tables
|
||||
rulesets will also see these packets.
|
||||
|
||||
br_netfilter is also the reason for the iptables *physdev* match:
|
||||
This match is the only way to reliably tell routed and bridged packets
|
||||
apart in an iptables ruleset.
|
||||
|
||||
Note that ebtables and nftables will work fine without the br_netfilter module.
|
||||
iptables/ip6tables/arptables do not work for bridged traffic because they
|
||||
plug in the routing stack. nftables rules in ip/ip6/inet/arp families won't
|
||||
see traffic that is forwarded by a bridge either, but that's very much how it
|
||||
should be.
|
||||
|
||||
Historically the feature set of ebtables was very limited (it still is),
|
||||
this module was added to pretend packets are routed and invoke the ipv4/ipv6
|
||||
netfilter hooks from the bridge so users had access to the more feature-rich
|
||||
iptables matching capabilities (including conntrack). nftables doesn't have
|
||||
this limitation, pretty much all features work regardless of the protocol family.
|
||||
|
||||
So, br_netfilter is only needed if users, for some reason, need to use
|
||||
ip(6)tables to filter packets forwarded by the bridge, or NAT bridged
|
||||
traffic. For pure link layer filtering, this module isn't needed.

FAQ
|
||||
===
|
||||
|
||||
What does a bridge do?
|
||||
----------------------
|
||||
|
||||
A bridge transparently forwards traffic between multiple network interfaces.
|
||||
In plain English this means that a bridge connects two or more physical
|
||||
Ethernet networks, to form one larger (logical) Ethernet network.
|
||||
|
||||
Is it L3 protocol independent?
|
||||
------------------------------
|
||||
|
||||
Yes. The bridge sees all frames, but it *uses* only L2 headers/information.
|
||||
As such, the bridging functionality is protocol independent, and there should
|
||||
be no trouble forwarding IPX, NetBEUI, IP, IPv6, etc.

||||
Firmware (FW) logging
|
||||
---------------------
|
||||
The driver supports FW logging via the debugfs interface on PF 0 only. The FW
|
||||
running on the NIC must support FW logging; if the FW doesn't support FW logging
|
||||
the 'fwlog' file will not get created in the ice debugfs directory.
|
||||
|
||||
Module configuration
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
Firmware logging is configured on a per module basis. Each module can be set to
|
||||
a value independent of the other modules (unless the module 'all' is specified).
|
||||
The modules will be instantiated under the 'fwlog/modules' directory.
|
||||
|
||||
The user can set the log level for a module by writing to the module file like
|
||||
this::
|
||||
|
||||
# echo <log_level> > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/<module>
|
||||
|
||||
where
|
||||
|
||||
* log_level is a name as described below. Each level includes the
|
||||
messages from the previous/lower level
|
||||
|
||||
* none
|
||||
* error
|
||||
* warning
|
||||
* normal
|
||||
* verbose
|
||||
|
||||
* module is a name that represents the module to receive events for. The
|
||||
module names are
|
||||
|
||||
* general
|
||||
* ctrl
|
||||
* link
|
||||
* link_topo
|
||||
* dnl
|
||||
* i2c
|
||||
* sdp
|
||||
* mdio
|
||||
* adminq
|
||||
* hdma
|
||||
* lldp
|
||||
* dcbx
|
||||
* dcb
|
||||
* xlr
|
||||
* nvm
|
||||
* auth
|
||||
* vpd
|
||||
* iosf
|
||||
* parser
|
||||
* sw
|
||||
* scheduler
|
||||
* txq
|
||||
* rsvd
|
||||
* post
|
||||
* watchdog

||||
* task_dispatch

* mng
|
||||
* synce
|
||||
* health
|
||||
* tsdrv
|
||||
* pfreg
|
||||
* mdlver
|
||||
* all
|
||||
|
||||
The name 'all' is special and allows the user to set all of the modules to the
|
||||
specified log_level or to read the log_level of all of the modules.
|
||||
|
||||
Example usage to configure the modules
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
To set a single module to 'verbose'::
|
||||
|
||||
# echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/link
|
||||
|
||||
To set multiple modules then issue the command multiple times::
|
||||
|
||||
# echo verbose > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/link
|
||||
# echo warning > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/ctrl
|
||||
# echo none > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/dcb
|
||||
|
||||
To set all the modules to the same value::
|
||||
|
||||
# echo normal > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/all
|
||||
|
||||
To read the log_level of a specific module (e.g. module 'general')::
|
||||
|
||||
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/general
|
||||
|
||||
To read the log_level of all the modules::
|
||||
|
||||
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/modules/all
|
||||
|
||||
Enabling FW log
|
||||
~~~~~~~~~~~~~~~
|
||||
Configuring the modules indicates to the FW that the configured modules should
|
||||
generate events that the driver is interested in, but it **does not** send the
|
||||
events to the driver until the enable message is sent to the FW. To do this
|
||||
the user can write a 1 (enable) or 0 (disable) to 'fwlog/enable'. An example
|
||||
is::
|
||||
|
||||
# echo 1 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/enable
|
||||
|
||||
Retrieving FW log data
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
The FW log data can be retrieved by reading from 'fwlog/data'. The user can
|
||||
write any value to 'fwlog/data' to clear the data. The data can only be cleared
|
||||
when FW logging is disabled. The FW log data is a binary file that is sent to
|
||||
Intel and used to help debug user issues.
|
||||
|
||||
An example to read the data is::
|
||||
|
||||
# cat /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data > fwlog.bin
|
||||
|
||||
An example to clear the data is::
|
||||
|
||||
# echo 0 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/data
|
||||
|
||||
Changing how often the log events are sent to the driver
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
The driver receives FW log data from the Admin Receive Queue (ARQ). The
|
||||
frequency that the FW sends the ARQ events can be configured by writing to
|
||||
'fwlog/nr_messages'. The range is 1-128 (1 means push every log message, 128
|
||||
means push only when the max AQ command buffer is full). The suggested value is
|
||||
10. The user can see what the value is configured to by reading
|
||||
'fwlog/nr_messages'. An example to set the value is::
|
||||
|
||||
# echo 50 > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/nr_messages
|
||||
|
||||
Configuring the amount of memory used to store FW log data
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
The driver stores FW log data within the driver. The default size of the memory
|
||||
used to store the data is 1MB. Some use cases may require more or less data so
|
||||
the user can change the amount of memory that is allocated for FW log data.
|
||||
To change the amount of memory then write to 'fwlog/log_size'. The value must be
|
||||
one of: 128K, 256K, 512K, 1M, or 2M. FW logging must be disabled to change the
|
||||
value. An example of changing the value is::
|
||||
|
||||
# echo 128K > /sys/kernel/debug/ice/0000\:18\:00.0/fwlog/log_size

Copyright |copy| 1998 Corey Thomas (corey@world.std.com)
|
||||
|
||||
This file is the documentation for the Raylink Wireless LAN card driver for
|
||||
Linux. The Raylink wireless LAN card is a PCMCIA card which provides IEEE
|
||||
802.11 compatible wireless network connectivity at 1 and 2 megabits/second.
|
||||
See http://www.raytheon.com/micro/raylink/ for more information on the Raylink
|
||||
card. This driver is in early development and does have bugs. See the known
|
||||
bugs and limitations at the end of this document for more information.
|
||||
This driver also works with WebGear's Aviator 2.4 and Aviator Pro
|
||||
wireless LAN cards.
|
||||
|
||||
As of kernel 2.3.18, the ray_cs driver is part of the Linux kernel
|
||||
source. My web page for the development of ray_cs is at
|
||||
http://web.ralinktech.com/ralink/Home/Support/Linux.html
|
||||
and I can be emailed at corey@world.std.com
|
||||
|
||||
The kernel driver is based on ray_cs-1.62.tgz
|
||||
|
||||
The driver at my web page is intended to be used as an add on to
|
||||
David Hinds pcmcia package. All the command line parameters are
|
||||
available when compiled as a module. When built into the kernel, only
|
||||
the essid= string parameter is available via the kernel command line.
|
||||
This will change after the method of sorting out parameters for all
|
||||
the PCMCIA drivers is agreed upon. If you must have a built in driver
|
||||
with nondefault parameters, they can be edited in
|
||||
/usr/src/linux/drivers/net/pcmcia/ray_cs.c. Searching for module_param
|
||||
will find them all.
|
||||
|
||||
Information on card services is available at:
|
||||
|
||||
http://pcmcia-cs.sourceforge.net/
|
||||
|
||||
|
||||
Card services user programs are still required for PCMCIA devices.
|
||||
pcmcia-cs-3.1.1 or greater is required for the kernel version of
|
||||
the driver.
|
||||
|
||||
Currently, ray_cs is not part of David Hinds card services package,
|
||||
so the following magic is required.
|
||||
|
||||
At the end of the /etc/pcmcia/config.opts file, add the line:
|
||||
source ./ray_cs.opts
|
||||
This will make card services read the ray_cs.opts file
|
||||
when starting. Create the file /etc/pcmcia/ray_cs.opts containing the
|
||||
following::
|
||||
|
||||

1 = translation (RFC1042/802.1)
|
||||
=============== =============== =============================================
|
||||
|
||||
More on sniffer mode:
|
||||
|
||||
tcpdump does not understand 802.11 headers, so it can't
|
||||
interpret the contents, but it can record to a file. This is only
|
||||
useful for debugging 802.11 lowlevel protocols that are not visible to
|
||||
linux. If you want to watch ftp xfers, or do similar things, you
|
||||
don't need to use sniffer mode. Also, some packet types are never
|
||||
sent up by the card, so you will never see them (ack, rts, cts, probe
|
||||
etc.) There is a simple program (showcap) included in the ray_cs
|
||||
package which parses the 802.11 headers.

Some NICs support symmetric RSS hashing where, if the IP (source address,

destination address) and TCP/UDP (source port, destination port) tuples

are swapped, the computed hash is the same. This is beneficial in some

applications that monitor TCP/IP flows (IDS, firewalls, ...etc) and need

both directions of the flow to land on the same Rx queue (and CPU). The

"Symmetric-XOR" is a type of RSS algorithms that achieves this hash
|

symmetry by XORing the input source and destination fields of the IP
|

and/or L4 protocols. This, however, results in reduced input entropy and

could potentially be exploited. Specifically, the algorithm XORs the input

# (SRC_IP ^ DST_IP, SRC_IP ^ DST_IP, SRC_PORT ^ DST_PORT, SRC_PORT ^ DST_PORT)

AF_XDP TX Metadata
|
||||
==================
|
||||
|
||||
This document describes how to enable offloads when transmitting packets
|
||||
via :doc:`af_xdp`. Refer to :doc:`xdp-rx-metadata` on how to access similar
|
||||
metadata on the receive side.
|
||||
|
||||
General Design
|
||||
==============
|
||||
|
||||
The headroom for the metadata is reserved via ``tx_metadata_len`` in
|
||||
``struct xdp_umem_reg``. The metadata length is therefore the same for
|
||||
every socket that shares the same umem. The metadata layout is a fixed UAPI,
|
||||
refer to ``union xsk_tx_metadata`` in ``include/uapi/linux/if_xdp.h``.
|
||||
Thus, generally, the ``tx_metadata_len`` field above should contain
|
||||
``sizeof(union xsk_tx_metadata)``.
|
||||
|
||||
The headroom and the metadata itself should be located right before
|
||||
``xdp_desc->addr`` in the umem frame. Within a frame, the metadata
|
||||
layout is as follows::
|
||||
|
||||
tx_metadata_len
|
||||
/ \
|
||||
+-----------------+---------+----------------------------+
|
||||
| xsk_tx_metadata | padding | payload |
|
||||
+-----------------+---------+----------------------------+
|
||||
^
|
||||
|
|
||||
xdp_desc->addr
|
||||
|
||||
An AF_XDP application can request headrooms larger than ``sizeof(struct
|
||||
xsk_tx_metadata)``. The kernel will ignore the padding (and will still
|
||||
use ``xdp_desc->addr - tx_metadata_len`` to locate
|
||||
the ``xsk_tx_metadata``). For the frames that shouldn't carry
|
||||
any metadata (i.e., the ones that don't have ``XDP_TX_METADATA`` option),
|
||||
the metadata area is ignored by the kernel as well.
|
||||
|
||||
The flags field enables the particular offload:
|
||||
|
||||
- ``XDP_TXMD_FLAGS_TIMESTAMP``: requests the device to put transmission
|
||||
timestamp into ``tx_timestamp`` field of ``union xsk_tx_metadata``.
|
||||
- ``XDP_TXMD_FLAGS_CHECKSUM``: requests the device to calculate L4
|
||||
checksum. ``csum_start`` specifies byte offset of where the checksumming
|
||||
should start and ``csum_offset`` specifies byte offset where the
|
||||
device should store the computed checksum.
|
||||
|
||||
Besides the flags above, in order to trigger the offloads, the first
|
||||
packet's ``struct xdp_desc`` descriptor should set ``XDP_TX_METADATA``
|
||||
bit in the ``options`` field. Also note that in a multi-buffer packet
|
||||
only the first chunk should carry the metadata.
|
||||
|
||||
Software TX Checksum
|
||||
====================
|
||||
|
||||
For development and testing purposes its possible to pass
|
||||
``XDP_UMEM_TX_SW_CSUM`` flag to ``XDP_UMEM_REG`` UMEM registration call.
|
||||
In this case, when running in ``XDK_COPY`` mode, the TX checksum
|
||||
is calculated on the CPU. Do not enable this option in production because
|
||||
it will negatively affect performance.
|
||||
|
||||
Querying Device Capabilities
|
||||
============================
|
||||
|
||||
Every devices exports its offloads capabilities via netlink netdev family.
|
||||
Refer to ``xsk-flags`` features bitmask in
|
||||
``Documentation/netlink/specs/netdev.yaml``.
|
||||
|
||||
- ``tx-timestamp``: device supports ``XDP_TXMD_FLAGS_TIMESTAMP``
|
||||
- ``tx-checksum``: device supports ``XDP_TXMD_FLAGS_CHECKSUM``
|
||||
|
||||
See ``tools/net/ynl/samples/netdev.c`` on how to query this information.
|
||||
|
||||
Example
|
||||
=======
|
||||
|
||||
See ``tools/testing/selftests/bpf/xdp_hw_metadata.c`` for an example
|
||||
program that handles TX metadata. Also see https://github.com/fomichev/xskgen
|
||||
for a more bare-bones example.

Sub-messages
|
||||
------------
|
||||
|
||||
Several raw netlink families such as
|
||||
:doc:`rt_link<../../networking/netlink_spec/rt_link>` and
|
||||
:doc:`tc<../../networking/netlink_spec/tc>` use attribute nesting as an
|
||||
abstraction to carry module specific information.
|
||||
|
||||
Conceptually it looks as follows::
|
||||
|
||||
[OUTER NEST OR MESSAGE LEVEL]
|
||||
[GENERIC ATTR 1]
|
||||
[GENERIC ATTR 2]
|
||||
[GENERIC ATTR 3]
|
||||
[GENERIC ATTR - wrapper]
|
||||
[MODULE SPECIFIC ATTR 1]
|
||||
[MODULE SPECIFIC ATTR 2]
|
||||
|
||||
The ``GENERIC ATTRs`` at the outer level are defined in the core (or rt_link or
|
||||
core TC), while specific drivers, TC classifiers, qdiscs etc. can carry their
|
||||
own information wrapped in the ``GENERIC ATTR - wrapper``. Even though the
|
||||
example above shows attributes nesting inside the wrapper, the modules generally
|
||||
have full freedom to define the format of the nest. In practice the payload of
|
||||
the wrapper attr has very similar characteristics to a netlink message. It may
|
||||
contain a fixed header / structure, netlink attributes, or both. Because of
|
||||
those shared characteristics we refer to the payload of the wrapper attribute as
|
||||
a sub-message.
|
||||
|
||||
A sub-message attribute uses the value of another attribute as a selector key to
|
||||
choose the right sub-message format. For example if the following attribute has
|
||||
already been decoded:
|
||||
|
||||
.. code-block:: json
|
||||
|
||||
{ "kind": "gre" }
|
||||
|
||||
and we encounter the following attribute spec:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
-
|
||||
name: data
|
||||
type: sub-message
|
||||
sub-message: linkinfo-data-msg
|
||||
selector: kind
|
||||
|
||||
Then we look for a sub-message definition called ``linkinfo-data-msg`` and use
|
||||
the value of the ``kind`` attribute i.e. ``gre`` as the key to choose the
|
||||
correct format for the sub-message:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
sub-messages:
|
||||
name: linkinfo-data-msg
|
||||
formats:
|
||||
-
|
||||
value: bridge
|
||||
attribute-set: linkinfo-bridge-attrs
|
||||
-
|
||||
value: gre
|
||||
attribute-set: linkinfo-gre-attrs
|
||||
-
|
||||
value: geneve
|
||||
attribute-set: linkinfo-geneve-attrs
|
||||
|
||||
This would decode the attribute value as a sub-message with the attribute-set
|
||||
called ``linkinfo-gre-attrs`` as the attribute space.
|
||||
|
||||
A sub-message can have an optional ``fixed-header`` followed by zero or more
|
||||
attributes from an ``attribute-set``. For example the following
|
||||
``tc-options-msg`` sub-message defines message formats that use a mixture of
|
||||
``fixed-header``, ``attribute-set`` or both together:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
sub-messages:
|
||||
-
|
||||
name: tc-options-msg
|
||||
formats:
|
||||
-
|
||||
value: bfifo
|
||||
fixed-header: tc-fifo-qopt
|
||||
-
|
||||
value: cake
|
||||
attribute-set: tc-cake-attrs
|
||||
-
|
||||
value: netem
|
||||
fixed-header: tc-netem-qopt
|
||||
attribute-set: tc-netem-attrs
|
||||
|
||||
Note that a selector attribute must appear in a netlink message before any
|
||||
sub-message attributes that depend on it.
