Networking changes for 6.13.
The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core
----
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read
access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code
--------------------------------------------
- Add small file operations for debugfs, to reduce the struct ops size.
- Refactoring and optimization for the implementation of page_frag API,
This is a preparatory work to consolidate the page_frag
implementation.
Netfilter
---------
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users
the option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent
CI improvements.
BPF
---
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols
---------
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after close,
the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per device
neigh lists.
Driver API
----------
- Introduce a unified interface to configure transmission H/W shaping,
and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling
-----------------
- forwarding: introduce deferred commands, to simplify
the cleanup phase

Note on buffer lengths not multiple of 4
|
||||||
|
----------------------------------------
|
||||||
|
|
||||||
|
To deal with memory layout quirks where groups of 4 bytes are laid out "little
|
||||||
|
endian" relative to each other, but "big endian" within the group itself, the
|
||||||
|
concept of groups of 4 bytes is intrinsic to the packing API (not to be
|
||||||
|
confused with the memory access, which is performed byte by byte, though).
|
||||||
|
|
||||||
|
With buffer lengths not multiple of 4, this means one group will be incomplete.
|
||||||
|
Depending on the quirks, this may lead to discontinuities in the bit fields
|
||||||
|
accessible through the buffer. The packing API assumes discontinuities were not
|
||||||
|
the intention of the memory layout, so it avoids them by effectively logically
|
||||||
|
shortening the most significant group of 4 octets to the number of octets
|
||||||
|
actually available.
|
||||||
|
|
||||||
|
Example with a 31 byte sized buffer given below. Physical buffer offsets are
|
||||||
|
implicit, and increase from left to right within a group, and from top to
|
||||||
|
bottom within a column.
|
||||||
|
|
||||||
|
No quirks:

title: NETC Blocks Control
|
||||||
|
|
||||||
|
description:
|
||||||
|
Usually, NETC has 2 blocks of 64KB registers, integrated endpoint register
|
||||||
|
block (IERB) and privileged register block (PRB). IERB is used for pre-boot
|
||||||
|
initialization for all NETC devices, such as ENETC, Timer, EMIDO and so on.
|
||||||
|
And PRB controls global reset and global error handling for NETC. Moreover,
|
||||||
|
for the i.MX platform, there is also a NETCMIX block for link configuration,
|
||||||
|
such as MII protocol, PCS protocol, etc.

|
||||||
|
- APB registers are used to configure clock frequency/clock enable/clock
|
||||||
|
direction/PHY interface type.
|
||||||
|
- AHB registers are use to configure GMAC core (DesignWare Core part).
|
||||||
|

inject skb (socket buffer) reallocation events into the network path. The
|
||||||
|
primary goal is to identify and prevent issues related to pointer
|
||||||
|
mismanagement in the network subsystem. By forcing skb reallocation at
|
||||||
|
strategic points, this feature creates scenarios where existing pointers to
|
||||||
|
skb headers become invalid.
|
||||||
|
|
||||||
|
When the fault is injected and the reallocation is triggered, cached pointers
|
||||||
|
to skb headers and data no longer reference valid memory locations. This
|
||||||
|
deliberate invalidation helps expose code paths where proper pointer updating
|
||||||
|
is neglected after a reallocation event.
|
||||||
|
|
||||||
|
By creating these controlled fault scenarios, the system can catch instances
|
||||||
|
where stale pointers are used, potentially leading to memory corruption or
|
||||||
|
system instability.
|
||||||
|
|
||||||
|
To select the interface to act on, write the network name to
|
||||||
|
/sys/kernel/debug/fail_skb_realloc/devname.
|
||||||
|
If this field is left empty (which is the default value), skb reallocation
|
||||||
|
will be forced on all network interfaces.
|
||||||
|
|
||||||
|
The effectiveness of this fault detection is enhanced when KASAN is
|
||||||
|
enabled, as it helps identify invalid memory references and use-after-free
|
||||||
|
(UAF) issues.

Networking HW rate limiting configuration.
|
||||||
|
|
||||||
|
This API allows configuring HW shapers available on the network
|
||||||
|
devices at different levels (queues, network device) and allows
|
||||||
|
arbitrary manipulation of the scheduling tree of the involved
|
||||||
|
shapers.
|
||||||
|
|
||||||
|
Each @shaper is identified within the given device, by a @handle,
|
||||||
|
comprising both a @scope and an @id.
|
||||||
|
|
||||||
|
Depending on the @scope value, the shapers are attached to specific
|
||||||
|
HW objects (queues, devices) or, for @node scope, represent a
|
||||||
|
scheduling group, that can be placed in an arbitrary location of
|
||||||
|
the scheduling tree.
|
||||||
|
|
||||||
|
Shapers can be created with two different operations: the @set
|
||||||
|
operation, to create and update a single "attached" shaper, and
|
||||||
|
the @group operation, to create and update a scheduling
|
||||||
|
group. Only the @group operation can create @node scope shapers.
|
||||||
|
|
||||||
|
Existing shapers can be deleted/reset via the @delete operation.
|
||||||
|
|
||||||
|
The user can query the running configuration via the @get operation.
|
||||||
|
|
||||||
|
Different devices can provide different feature sets, e.g. with no
|
||||||
|
support for complex scheduling hierarchy, or for some shaping
|
||||||
|
parameters. The user can introspect the HW capabilities via the
|
||||||
|
@cap-get operation.

Clear (remove) the specified shaper. When deleting

a @node shaper, reattach all the node's leaves to the

deleted node's parent.
|
||||||

If, after the removal, the parent shaper has no more

leaves and the parent shaper scope is @node, the parent

node is deleted, recursively.
|

When deleting a @queue shaper or a @netdev shaper,
|
||||||
|
the shaper disappears from the hierarchy, but the
|
||||||
|
queue/device can still send traffic: it has an implicit
|
||||||
|
node with infinite bandwidth. The queue's implicit node
|
||||||
|
feeds an implicit RR node at the root of the hierarchy.

Create or update a scheduling group, attaching the specified

@leaves shapers under the specified node identified by @handle.
|

|
The @leaves shapers scope must be @queue and the node shaper
|
||||||
|
scope must be either @node or @netdev.
|
||||||
|
When the node shaper has @node scope, if the @handle @id is not
|
||||||
|
specified, a new shaper of such scope is created, otherwise the
|
||||||
|
specified node must already exist.
|
||||||
|
When updating an existing node shaper, the specified @leaves are
|
||||||
|
added to the existing node; such node will also retain any preexisting
|
||||||
|
leave.
|
||||||
|
The @parent handle for a new node shaper defaults to the parent
|
||||||
|
of all the leaves, provided all the leaves share the same parent.
|
||||||
|
Otherwise @parent handle must be specified.
|
||||||
|
The user can optionally provide shaping attributes for the node
|
||||||
|
shaper.
|
||||||
|
The operation is atomic, on failure no change is applied to
|
||||||
|
the device shaping configuration, otherwise the @node shaper
|
||||||
|
full identifier, comprising @binding and @handle, is provided
|

ethtool reset
|
||||||
|
-------------
|
||||||
|
The driver supports 3 types of resets:
|
||||||
|
|
||||||
|
- PF reset - resets only components associated with the given PF, does not
|
||||||
|
impact other PFs
|
||||||
|
|
||||||
|
- CORE reset - whole adapter is affected, reset all PFs
|
||||||
|
|
||||||
|
- GLOBAL reset - same as CORE but mac and phy components are also reinitialized
|
||||||
|
|
||||||
|
These are mapped to ethtool reset flags as follow:
|
||||||
|
|
||||||
|
- PF reset:
|
||||||
|
|
||||||
|
# ethtool --reset <ethX> irq dma filter offload
|
||||||
|
|
||||||
|
- CORE reset:
|
||||||
|
|
||||||
|
# ethtool --reset <ethX> irq-shared dma-shared filter-shared offload-shared \
|
||||||
|
ram-shared
|
||||||
|
|
||||||
|
- GLOBAL reset:
|
||||||
|
|
||||||
|
# ethtool --reset <ethX> irq-shared dma-shared filter-shared offload-shared \
|
||||||
|
mac-shared phy-shared ram-shared
|
||||||
|
|
||||||
|
In switchdev mode you can reset a VF using port representor:
|
||||||
|
|
||||||
|
# ethtool --reset <repr> irq dma filter offload

RVU Representors
|
||||||
|
================
|
||||||
|
|
||||||
|
RVU representor driver adds support for creation of representor devices for
|
||||||
|
RVU PFs' VFs in the system. Representor devices are created when user enables
|
||||||
|
the switchdev mode.
|
||||||
|
Switchdev mode can be enabled either before or after setting up SRIOV numVFs.
|
||||||
|
All representor devices share a single NIXLF but each has a dedicated Rx/Tx
|
||||||
|
queues. RVU PF representor driver registers a separate netdev for each
|
||||||
|
Rx/Tx queue pair.
|
||||||
|
|
||||||
|
Current HW does not support built-in switch which can do L2 learning and
|
||||||
|
forwarding packets between representee and representor. Hence, packet path
|
||||||
|
between representee and it's representor is achieved by setting up appropriate
|
||||||
|
NPC MCAM filters.
|
||||||
|
Transmit packets matching these filters will be loopbacked through hardware
|
||||||
|
loopback channel/interface (i.e, instead of sending them out of MAC interface).
|
||||||
|
Which will again match the installed filters and will be forwarded.
|
||||||
|
This way representee => representor and representor => representee packet
|
||||||
|
path is achieved. These rules get installed when representors are created
|
||||||
|
and gets active/deactivate based on the representor/representee interface state.
|
||||||
|
|
||||||
|
Usage example:
|
||||||
|
|
||||||
|
- Change device to switchdev mode::
|
||||||
|
|
||||||
|
# devlink dev eswitch set pci/0002:1c:00.0 mode switchdev

|
||||||
|
(``pcie_stats``). These statistics provide insights into PCIe transaction
|
||||||
|
behavior and potential performance bottlenecks.
|
||||||
|
|
||||||
|

|
||||||
|
Introduction
|
||||||
|
------------
|
||||||
|
|
||||||
|
This documentation is designed for two primary audiences:
|
||||||
|
|
||||||
|
1. **Users and System Administrators**: For those dealing with real-world
|
||||||
|
Ethernet issues, this guide provides a practical, step-by-step
|
||||||
|
troubleshooting flow to help identify and resolve common problems in Twisted
|
||||||
|
Pair Ethernet at OSI Layer 1. If you're facing unstable links, speed drops,
|
||||||
|
or mysterious network issues, jump right into the step-by-step guide and
|
||||||
|
follow it through to find your solution.
|
||||||
|
|
||||||
|
2. **Kernel Developers**: For developers working with network drivers and PHY
|
||||||
|
support, this documentation outlines the diagnostic process and highlights
|
||||||
|
areas where the Linux kernel’s diagnostic interfaces could be extended or
|
||||||
|
improved. By understanding the diagnostic flow, developers can better
|
||||||
|
prioritize future enhancements.
|
||||||
|
|
||||||
|
Step-by-Step Diagnostic Guide from Linux (General Ethernet)
|
||||||
|
-----------------------------------------------------------
|
||||||
|
|
||||||
|
This diagnostic guide covers common Ethernet troubleshooting scenarios,
|
||||||
|
focusing on **link stability and detection** across different Ethernet
|
||||||
|
environments, including **Single-Pair Ethernet (SPE)** and **Multi-Pair
|
||||||
|
Ethernet (MPE)**, as well as power delivery technologies like **PoDL** (Power
|
||||||
|
over Data Line) and **PoE** (Clause 33 PSE).
|
||||||
|
|
||||||
|
The guide is designed to help users diagnose physical layer (Layer 1) issues on
|
||||||
|
systems running **Linux kernel version 6.11 or newer**, utilizing **ethtool
|
||||||
|
version 6.10 or later** and **iproute2 version 6.4.0 or later**.
|
||||||
|
|
||||||
|
In this guide, we assume that users may have **limited or no access to the link
|
||||||
|
partner** and will focus on diagnosing issues locally.
|
||||||
|
|
||||||
|
Diagnostic Scenarios
|
||||||
|
~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
- **Link is up and stable, but no data transfer**: If the link is stable but
|
||||||
|
there are issues with data transmission, refer to the **OSI Layer 2
|
||||||
|
Troubleshooting Guide**.
|
||||||
|
|
||||||
|
- **Link is unstable**: Link resets, speed drops, or other fluctuations
|
||||||
|
indicate potential issues at the hardware or physical layer.
|
||||||
|
|
||||||
|
- **No link detected**: The interface is up, but no link is established.
|
||||||
|
|
||||||
|
Verify Interface Status
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
Begin by verifying the status of the Ethernet interface to check if it is
|
||||||
|
administratively up. Unlike `ethtool`, which provides information on the link
|
||||||
|
and PHY status, it does not show the **administrative state** of the interface.
|
||||||
|
To check this, you should use the `ip` command, which describes the interface
|
||||||
|
state within the angle brackets `"<>"` in its output.
|
||||||
|
|
||||||
|
For example, in the output `<NO-CARRIER,BROADCAST,MULTICAST,UP>`, the important
|
||||||
|
keywords are:
|
||||||
|
|
||||||
|
- **UP**: The interface is in the administrative "UP" state.
|
||||||
|
- **NO-CARRIER**: The interface is administratively up, but no physical link is
|
||||||
|
detected.
|
||||||
|
|
||||||
|
If the output shows `<BROADCAST,MULTICAST>`, this indicates the interface is in
|
||||||
|
the administrative "DOWN" state.
|
||||||
|
|
||||||
|
- **Command:** `ip link show dev <interface>`
|
||||||
|
|
||||||
|
- **Expected Output:**
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
4: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 ...
|
||||||
|
link/ether 88:14:2b:00:96:f2 brd ff:ff:ff:ff:ff:ff
|
||||||
|
|
||||||
|
- **Interpreting the Output:**
|
||||||
|
|
||||||
|
- **Administrative UP State**:
|
||||||
|
|
||||||
|
- If the output contains **"UP"**, the interface is administratively up,
|
||||||
|
and the system is trying to establish a physical link.
|
||||||
|
|
||||||
|
- If you also see **"NO-CARRIER"**, it means the physical link has not been
|
||||||
|
detected, indicating potential Layer 1 issues like a cable fault,
|
||||||
|
misconfiguration, or no connection at the link partner. In this case,
|
||||||
|
proceed to the **Inspect Link Status and PHY Configuration** section.
|
||||||
|
|
||||||
|
- **Administrative DOWN State**:
|
||||||
|
|
||||||
|
- If the output lacks **"UP"** and shows only states like
|
||||||
|
**"<BROADCAST,MULTICAST>"**, it means the interface is administratively
|
||||||
|
down. In this case, bring the interface up using the following command:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ip link set dev <interface> up
|
||||||
|
|
||||||
|
- **Next Steps**:
|
||||||
|
|
||||||
|
- If the interface is **administratively up** but shows **NO-CARRIER**,
|
||||||
|
proceed to the **Inspect Link Status and PHY Configuration** section to
|
||||||
|
troubleshoot potential physical layer issues.
|
||||||
|
|
||||||
|
- If the interface was **administratively down** and you have brought it up,
|
||||||
|
ensure to **repeat this verification step** to confirm the new state of the
|
||||||
|
interface before proceeding
|
||||||
|
|
||||||
|
- **If the interface is up and the link is detected**:
|
||||||
|
|
||||||
|
- If the output shows **"UP"** and there is **no `NO-CARRIER`**, the
|
||||||
|
interface is administratively up, and the physical link has been
|
||||||
|
successfully established. If everything is working as expected, the Layer
|
||||||
|
1 diagnostics are complete, and no further action is needed.
|
||||||
|
|
||||||
|
- If the interface is up and the link is detected but **no data is being
|
||||||
|
transferred**, the issue is likely beyond Layer 1, and you should proceed
|
||||||
|
with diagnosing the higher layers of the OSI model. This may involve
|
||||||
|
checking Layer 2 configurations (such as VLANs or MAC address issues),
|
||||||
|
Layer 3 settings (like IP addresses, routing, or ARP), or Layer 4 and
|
||||||
|
above (firewalls, services, etc.).
|
||||||
|
|
||||||
|
- If the **link is unstable** or **frequently resetting or dropping**, this
|
||||||
|
may indicate a physical layer issue such as a faulty cable, interference,
|
||||||
|
or power delivery problems. In this case, proceed with the next step in
|
||||||
|
this guide.
|
||||||
|
|
||||||
|
Inspect Link Status and PHY Configuration
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
Use `ethtool -I` to check the link status, PHY configuration, supported link
|
||||||
|
modes, and additional statistics such as the **Link Down Events** counter. This
|
||||||
|
step is essential for diagnosing Layer 1 problems such as speed mismatches,
|
||||||
|
duplex issues, and link instability.
|
||||||
|
|
||||||
|
For both **Single-Pair Ethernet (SPE)** and **Multi-Pair Ethernet (MPE)**
|
||||||
|
devices, you will use this step to gather key details about the link. **SPE**
|
||||||
|
links generally support a single speed and mode without autonegotiation (with
|
||||||
|
the exception of **10BaseT1L**), while **MPE** devices typically support
|
||||||
|
multiple link modes and autonegotiation.
|
||||||
|
|
||||||
|
- **Command:** `ethtool -I <interface>`
|
||||||
|
|
||||||
|
- **Example Output for SPE Interface (Non-autonegotiation)**:

- **Next Steps**:
|
||||||
|
|
||||||
|
- Record the output provided by `ethtool`, particularly noting the
|
||||||
|
**master-slave status**, **speed**, **duplex**, and other relevant fields.
|
||||||
|
This information will be useful for further analysis or troubleshooting.
|
||||||
|
Once the **ethtool** output has been collected and stored, move on to the
|
||||||
|
next diagnostic step.
|
||||||
|
|
||||||
|
Check Power Delivery (PoDL or PoE)
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
If it is known that **PoDL** or **PoE** is **not implemented** on the system,
|
||||||
|
or the **PSE** (Power Sourcing Equipment) is managed by proprietary user-space
|
||||||
|
software or external tools, you can skip this step. In such cases, verify power
|
||||||
|
delivery through alternative methods, such as checking hardware indicators
|
||||||
|
(LEDs), using multimeters, or consulting vendor-specific software for
|
||||||
|
monitoring power status.
|
||||||
|
|
||||||
|
If **PoDL** or **PoE** is implemented and managed directly by Linux, follow
|
||||||
|
these steps to ensure power is being delivered correctly:
|
||||||
|
|
||||||
|
- **Command:** `ethtool --show-pse <interface>`
|
||||||
|
|
||||||
|
- **Expected Output Examples**:
|
||||||
|
|
||||||
|
1. **PSE Not Supported**:
|
||||||
|
|
||||||
|
If no PSE is attached or the interface does not support PSE, the following
|
||||||
|
output is expected:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
netlink error: No PSE is attached
|
||||||
|
netlink error: Operation not supported
|
||||||
|
|
||||||
|
2. **PoDL (Single-Pair Ethernet)**:
|
||||||
|
|
||||||
|
When PoDL is implemented, you might see the following attributes:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
PSE attributes for eth1:
|
||||||
|
PoDL PSE Admin State: enabled
|
||||||
|
PoDL PSE Power Detection Status: delivering power
|
||||||
|
|
||||||
|
3. **PoE (Clause 33 PSE)**:
|
||||||
|
|
||||||
|
For standard PoE, the output may look like this:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
PSE attributes for eth1:
|
||||||
|
Clause 33 PSE Admin State: enabled
|
||||||
|
Clause 33 PSE Power Detection Status: delivering power
|
||||||
|
Clause 33 PSE Available Power Limit: 18000
|
||||||
|
|
||||||
|
- **Adjust Power Limit (if needed)**:
|
||||||
|
|
||||||
|
- Sometimes, the available power limit may not be sufficient for the link
|
||||||
|
partner. You can increase the power limit as needed.
|
||||||
|
|
||||||
|
- **Command:** `ethtool --set-pse <interface> c33-pse-avail-pw-limit <limit>`
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool --set-pse eth1 c33-pse-avail-pw-limit 18000
|
||||||
|
ethtool --show-pse eth1
|
||||||
|
|
||||||
|
**Expected Output** after adjusting the power limit:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
Clause 33 PSE Available Power Limit: 18000
|
||||||
|
|
||||||
|
|
||||||
|
- **Next Steps**:
|
||||||
|
|
||||||
|
- **PoE or PoDL Not Used**: If **PoE** or **PoDL** is not implemented or used
|
||||||
|
on the system, proceed to the next diagnostic step, as power delivery is
|
||||||
|
not relevant for this setup.
|
||||||
|
|
||||||
|
- **PoE or PoDL Controlled Externally**: If **PoE** or **PoDL** is used but
|
||||||
|
is not managed by the Linux kernel's **PSE-PD** framework (i.e., it is
|
||||||
|
controlled by proprietary user-space software or external tools), this part
|
||||||
|
is out of scope for this documentation. Please consult vendor-specific
|
||||||
|
documentation or external tools for monitoring and managing power delivery.
|
||||||
|
|
||||||
|
- **PSE Admin State Disabled**:
|
||||||
|
|
||||||
|
- If the `PSE Admin State:` is **disabled**, enable it by running one of
|
||||||
|
the following commands:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool --set-pse <devname> podl-pse-admin-control enable
|
||||||
|
|
||||||
|
or, for Clause 33 PSE (PoE):
|
||||||
|
|
||||||
|
ethtool --set-pse <devname> c33-pse-admin-control enable
|
||||||
|
|
||||||
|
- After enabling the PSE Admin State, return to the start of the **Check
|
||||||
|
Power Delivery (PoDL or PoE)** step to recheck the power delivery status.
|
||||||
|
|
||||||
|
- **Power Not Delivered**: If the `Power Detection Status` shows something
|
||||||
|
other than "delivering power" (e.g., `over current`), troubleshoot the
|
||||||
|
**PSE**. Check for potential issues such as a short circuit in the cable,
|
||||||
|
insufficient power delivery, or a fault in the PSE itself.
|
||||||
|
|
||||||
|
- **Power Delivered but No Link**: If power is being delivered but no link is
|
||||||
|
established, proceed with further diagnostics by performing **Cable
|
||||||
|
Diagnostics** or reviewing the **Inspect Link Status and PHY
|
||||||
|
Configuration** steps to identify any underlying issues with the physical
|
||||||
|
link or settings.
|
||||||
|
|
||||||
|
Cable Diagnostics
|
||||||
|
~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
Use `ethtool` to test for physical layer issues such as cable faults. The test
|
||||||
|
results can vary depending on the cable's condition, the technology in use, and
|
||||||
|
the state of the link partner. The results from the cable test will help in
|
||||||
|
diagnosing issues like open circuits, shorts, impedance mismatches, and
|
||||||
|
noise-related problems.
|
||||||
|
|
||||||
|
- **Command:** `ethtool --cable-test <interface>`
|
||||||
|
|
||||||
|
The following are the typical outputs for **Single-Pair Ethernet (SPE)** and
|
||||||
|
**Multi-Pair Ethernet (MPE)**:
|
||||||
|
|
||||||
|
- **For Single-Pair Ethernet (SPE)**:
|
||||||
|
- **Expected Output (SPE)**:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
Cable test completed for device eth1.
|
||||||
|
Pair A, fault length: 25.00m
|
||||||
|
Pair A code Open Circuit
|
||||||
|
|
||||||
|
This indicates an open circuit or cable fault at the reported distance, but
|
||||||
|
results can be influenced by the link partner's state. Refer to the
|
||||||
|
**"Troubleshooting Based on Cable Test Results"** section for further
|
||||||
|
interpretation of these results.
|
||||||
|
|
||||||
|
- **For Multi-Pair Ethernet (MPE)**:
|
||||||
|
- **Expected Output (MPE)**:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
Cable test completed for device eth0.
|
||||||
|
Pair A code OK
|
||||||
|
Pair B code OK
|
||||||
|
Pair C code Open Circuit
|
||||||
|
|
||||||
|
Here, Pair C is reported as having an open circuit, while Pairs A and B are
|
||||||
|
functioning correctly. However, if autonegotiation is in use on Pairs A and
|
||||||
|
B, the cable test may be disrupted. Refer to the **"Troubleshooting Based on
|
||||||
|
Cable Test Results"** section for a detailed explanation of these issues and
|
||||||
|
how to resolve them.
|
||||||
|
|
||||||
|
For detailed descriptions of the different possible cable test results, please
|
||||||
|
refer to the **"Troubleshooting Based on Cable Test Results"** section.
|
||||||
|
|
||||||
|
Troubleshooting Based on Cable Test Results
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
After running the cable test, the results can help identify specific issues in
|
||||||
|
the physical connection. However, it is important to note that **cable testing
|
||||||
|
results heavily depend on the capabilities and characteristics of both the
|
||||||
|
local hardware and the link partner**. The accuracy and reliability of the
|
||||||
|
results can vary significantly between different hardware implementations.
|
||||||
|
|
||||||
|
In some cases, this can introduce **blind spots** in the current cable testing
|
||||||
|
implementation, where certain results may not accurately reflect the actual
|
||||||
|
physical state of the cable. For example:
|
||||||
|
|
||||||
|
- An **Open Circuit** result might not only indicate a damaged or disconnected
|
||||||
|
cable but also occur if the cable is properly attached to a powered-down link
|
||||||
|
partner.
|
||||||
|
|
||||||
|
- Some PHYs may report a **Short within Pair** if the link partner is in
|
||||||
|
**forced slave mode**, even though there is no actual short in the cable.
|
||||||
|
|
||||||
|
To help users interpret the results more effectively, it could be beneficial to
|
||||||
|
extend the **kernel UAPI** (User API) to provide additional context or
|
||||||
|
**possible variants** of issues based on the hardware’s characteristics. Since
|
||||||
|
these quirks are often hardware-specific, the **kernel driver** would be an
|
||||||
|
ideal source of such information. By providing flags or hints related to
|
||||||
|
potential false positives for each test result, users would have a better
|
||||||
|
understanding of what to verify and where to investigate further.
|
||||||
|
|
||||||
|
Until such improvements are made, users should be aware of these limitations
|
||||||
|
and manually verify cable issues as needed. Physical inspections may help
|
||||||
|
resolve uncertainties related to false positive results.
|
||||||
|
|
||||||
|
The results can be one of the following:
|
||||||
|
|
||||||
|
- **OK**:
|
||||||
|
|
||||||
|
- The cable is functioning correctly, and no issues were detected.
|
||||||
|
|
||||||
|
- **Next Steps**: If you are still experiencing issues, it might be related
|
||||||
|
to higher-layer problems, such as duplex mismatches or speed negotiation,
|
||||||
|
which are not physical-layer issues.
|
||||||
|
|
||||||
|
- **Special Case for `BaseT1` (1000/100/10BaseT1)**: In `BaseT1` systems, an
|
||||||
|
"OK" result typically also means that the link is up and likely in **slave
|
||||||
|
mode**, since cable tests usually only pass in this mode. For some
|
||||||
|
**10BaseT1L** PHYs, an "OK" result may occur even if the cable is too long
|
||||||
|
for the PHY's configured range (for example, when the range is configured
|
||||||
|
for short-distance mode).
|
||||||
|
|
||||||
|
- **Open Circuit**:
|
||||||
|
|
||||||
|
- An **Open Circuit** result typically indicates that the cable is damaged or
|
||||||
|
disconnected at the reported fault length. Consider these possibilities:
|
||||||
|
|
||||||
|
- If the link partner is in **admin down** state or powered off, you might
|
||||||
|
still get an "Open Circuit" result even if the cable is functional.
|
||||||
|
|
||||||
|
- **Next Steps**: Inspect the cable at the fault length for visible damage
|
||||||
|
or loose connections. Verify the link partner is powered on and in the
|
||||||
|
correct mode.
|
||||||
|
|
||||||
|
- **Short within Pair**:
|
||||||
|
|
||||||
|
- A **Short within Pair** indicates an unintended connection within the same
|
||||||
|
pair of wires, typically caused by physical damage to the cable.
|
||||||
|
|
||||||
|
- **Next Steps**: Replace or repair the cable and check for any physical
|
||||||
|
damage or improperly crimped connectors.
|
||||||
|
|
||||||
|
- **Short to Another Pair**:
|
||||||
|
|
||||||
|
- A **Short to Another Pair** means the wires from different pairs are
|
||||||
|
shorted, which could occur due to physical damage or incorrect wiring.
|
||||||
|
|
||||||
|
- **Next Steps**: Replace or repair the damaged cable. Inspect the cable for
|
||||||
|
incorrect terminations or pinched wiring.
|
||||||
|
|
||||||
|
- **Impedance Mismatch**:
|
||||||
|
|
||||||
|
- **Impedance Mismatch** indicates a reflection caused by an impedance
|
||||||
|
discontinuity in the cable. This can happen when a part of the cable has
|
||||||
|
abnormal impedance (e.g., when different cable types are spliced together
|
||||||
|
or when there is a defect in the cable).
|
||||||
|
|
||||||
|
- **Next Steps**: Check the cable quality and ensure consistent impedance
|
||||||
|
throughout its length. Replace any sections of the cable that do not meet
|
||||||
|
specifications.
|
||||||
|
|
||||||
|
- **Noise**:
|
||||||
|
|
||||||
|
- **Noise** means that the Time Domain Reflectometry (TDR) test could not
|
||||||
|
complete due to excessive noise on the cable, which can be caused by
|
||||||
|
interference from electromagnetic sources.
|
||||||
|
|
||||||
|
- **Next Steps**: Identify and eliminate sources of electromagnetic
|
||||||
|
interference (EMI) near the cable. Consider using shielded cables or
|
||||||
|
rerouting the cable away from noise sources.
|
||||||
|
|
||||||
|
- **Resolution Not Possible**:
|
||||||
|
|
||||||
|
- **Resolution Not Possible** means that the TDR test could not detect the
|
||||||
|
issue due to the resolution limitations of the test or because the fault is
|
||||||
|
beyond the distance that the test can measure.
|
||||||
|
|
||||||
|
- **Next Steps**: Inspect the cable manually if possible, or use alternative
|
||||||
|
diagnostic tools that can handle greater distances or higher resolution.
|
||||||
|
|
||||||
|
- **Unknown**:
|
||||||
|
|
||||||
|
- An **Unknown** result may occur when the test cannot classify the fault or
|
||||||
|
when a specific issue is outside the scope of the tool's detection
|
||||||
|
capabilities.
|
||||||
|
|
||||||
|
- **Next Steps**: Re-run the test, verify the link partner's state, and inspect
|
||||||
|
the cable manually if necessary.
|
||||||
|
|
||||||
|
Verify Link Partner PHY Configuration
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
If the cable test passes but the link is still not functioning correctly, it’s
|
||||||
|
essential to verify the configuration of the link partner’s PHY. Mismatches in
|
||||||
|
speed, duplex settings, or master-slave roles can cause connection issues.
|
||||||
|
|
||||||
|
Autonegotiation Mismatch
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
- If both link partners support autonegotiation, ensure that autonegotiation is
|
||||||
|
enabled on both sides and that all supported link modes are advertised. A
|
||||||
|
mismatch can lead to connectivity problems or sub optimal performance.
|
||||||
|
|
||||||
|
- **Quick Fix:** Reset autonegotiation to the default settings, which will
|
||||||
|
advertise all default link modes:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool -s <interface> autoneg on
|
||||||
|
|
||||||
|
- **Command to check configuration:** `ethtool <interface>`
|
||||||
|
|
||||||
|
- **Expected Output:** Ensure that both sides advertise compatible link modes.
|
||||||
|
If autonegotiation is off, verify that both link partners are configured for
|
||||||
|
the same speed and duplex.
|
||||||
|
|
||||||
|
The following example shows a case where the local PHY advertises fewer link
|
||||||
|
modes than it supports. This will reduce the number of overlapping link modes
|
||||||
|
with the link partner. In the worst case, there will be no common link modes,
|
||||||
|
and the link will not be created:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
Settings for eth0:
|
||||||
|
Supported link modes: 1000baseT/Full, 100baseT/Full
|
||||||
|
Advertised link modes: 1000baseT/Full
|
||||||
|
Speed: 1000Mb/s
|
||||||
|
Duplex: Full
|
||||||
|
Auto-negotiation: on
|
||||||
|
|
||||||
|
Combined Mode Mismatch (Autonegotiation on One Side, Forced on the Other)
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
- One possible issue occurs when one side is using **autonegotiation** (as in
|
||||||
|
most modern systems), and the other side is set to a **forced link mode**
|
||||||
|
(e.g., older hardware with single-speed hubs). In such cases, modern PHYs
|
||||||
|
will attempt to detect the forced mode on the other side. If the link is
|
||||||
|
established, you may notice:
|
||||||
|
|
||||||
|
- **No or empty "Link partner advertised link modes"**.
|
||||||
|
|
||||||
|
- **"Link partner advertised auto-negotiation:"** will be **"no"** or not
|
||||||
|
present.
|
||||||
|
|
||||||
|
- This type of detection does not always work reliably:
|
||||||
|
|
||||||
|
- Typically, the modern PHY will default to **Half Duplex**, even if the link
|
||||||
|
partner is actually configured for **Full Duplex**.
|
||||||
|
|
||||||
|
- Some PHYs may not work reliably if the link partner switches from one
|
||||||
|
forced mode to another. In this case, only a down/up cycle may help.
|
||||||
|
|
||||||
|
- **Next Steps**: Set both sides to the same fixed speed and duplex mode to
|
||||||
|
avoid potential detection issues.
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool -s <interface> speed 1000 duplex full autoneg off
|
||||||
|
|
||||||
|
Master/Slave Role Mismatch (BaseT1 and 1000BaseT PHYs)
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
- In **BaseT1** systems (e.g., 1000BaseT1, 100BaseT1), link establishment
|
||||||
|
requires that one device is configured as **master** and the other as
|
||||||
|
**slave**. A mismatch in this master-slave configuration can prevent the link
|
||||||
|
from being established. However, **1000BaseT** also supports configurable
|
||||||
|
master/slave roles and can face similar issues.
|
||||||
|
|
||||||
|
- **Role Preference in 1000BaseT**: The **1000BaseT** specification allows link
|
||||||
|
partners to negotiate master-slave roles or role preferences during
|
||||||
|
autonegotiation. Some PHYs have hardware limitations or bugs that prevent
|
||||||
|
them from functioning properly in certain roles. In such cases, drivers may
|
||||||
|
force these PHYs into a specific role (e.g., **forced master** or **forced
|
||||||
|
slave**) or try a weaker option by setting preferences. If both link partners
|
||||||
|
have the same issue and are forced into the same mode (e.g., both forced into
|
||||||
|
master mode), they will not be able to establish a link.
|
||||||
|
|
||||||
|
- **Next Steps**: Ensure that one side is configured as **master** and the
|
||||||
|
other as **slave** to avoid this issue, particularly when hardware
|
||||||
|
limitations are involved, or try the weaker **preferred** option instead of
|
||||||
|
**forced**. Check for any driver-related restrictions or forced modes.
|
||||||
|
|
||||||
|
- **Command to force master/slave mode**:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool -s <interface> master-slave forced-master
|
||||||
|
|
||||||
|
or:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool -s <interface> master-slave forced-master speed 1000 duplex full autoneg off
|
||||||
|
|
||||||
|
|
||||||
|
- **Check the current master/slave status**:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool <interface>
|
||||||
|
|
||||||
|
Example Output:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
master-slave cfg: forced-master
|
||||||
|
master-slave status: master
|
||||||
|
|
||||||
|
- **Hardware Bugs and Driver Forcing**: If a known hardware issue forces the
|
||||||
|
PHY into a specific mode, it’s essential to check the driver source code or
|
||||||
|
hardware documentation for details. Ensure that the roles are compatible
|
||||||
|
across both link partners, and if both PHYs are forced into the same mode,
|
||||||
|
adjust one side accordingly to resolve the mismatch.
|
||||||
|
|
||||||
|
Monitor Link Resets and Speed Drops
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
If the link is unstable, showing frequent resets or speed drops, this may
|
||||||
|
indicate issues with the cable, PHY configuration, or environmental factors.
|
||||||
|
While there is still no completely unified way in Linux to directly monitor
|
||||||
|
downshift events or link speed changes via user space tools, both the Linux
|
||||||
|
kernel logs and `ethtool` can provide valuable insights, especially if the
|
||||||
|
driver supports reporting such events.
|
||||||
|
|
||||||
|
- **Monitor Kernel Logs for Link Resets and Speed Drops**:
|
||||||
|
|
||||||
|
- The Linux kernel will print link status changes, including downshift
|
||||||
|
events, in the system logs. These messages typically include speed changes,
|
||||||
|
duplex mode, and downshifted link speed (if the driver supports it).
|
||||||
|
|
||||||
|
- **Command to monitor kernel logs in real-time:**
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
dmesg -w | grep "Link is Up\|Link is Down"
|
||||||
|
|
||||||
|
- Example Output (if a downshift occurs):
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
eth0: Link is Up - 100Mbps/Full (downshifted) - flow control rx/tx
|
||||||
|
eth0: Link is Down
|
||||||
|
|
||||||
|
This indicates that the link has been established but has downshifted from
|
||||||
|
a higher speed.
|
||||||
|
|
||||||
|
- **Note**: Not all drivers or PHYs support downshift reporting, so you may
|
||||||
|
not see this information for all devices.
|
||||||
|
|
||||||
|
- **Monitor Link Down Events Using `ethtool`**:
|
||||||
|
|
||||||
|
- Starting with the latest kernel and `ethtool` versions, you can track
|
||||||
|
**Link Down Events** using the `ethtool -I` command. This will provide
|
||||||
|
counters for link drops, helping to diagnose link instability issues if
|
||||||
|
supported by the driver.
|
||||||
|
|
||||||
|
- **Command to monitor link down events:**
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool -I <interface>
|
||||||
|
|
||||||
|
- Example Output (if supported):
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
PSE attributes for eth1:
|
||||||
|
Link Down Events: 5
|
||||||
|
|
||||||
|
This indicates that the link has dropped 5 times. Frequent link down events
|
||||||
|
may indicate cable or environmental issues that require further
|
||||||
|
investigation.
|
||||||
|
|
||||||
|
- **Check Link Status and Speed**:
|
||||||
|
|
||||||
|
- Even though downshift counts or events are not easily tracked, you can
|
||||||
|
still use `ethtool` to manually check the current link speed and status.
|
||||||
|
|
||||||
|
- **Command:** `ethtool <interface>`
|
||||||
|
|
||||||
|
- **Expected Output:**
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
Speed: 1000Mb/s
|
||||||
|
Duplex: Full
|
||||||
|
Auto-negotiation: on
|
||||||
|
Link detected: yes
|
||||||
|
|
||||||
|
Any inconsistencies in the expected speed or duplex setting could indicate
|
||||||
|
an issue.
|
||||||
|
|
||||||
|
- **Disable Energy-Efficient Ethernet (EEE) for Diagnostics**:
|
||||||
|
|
||||||
|
- **EEE** (Energy-Efficient Ethernet) can be a source of link instability due
|
||||||
|
to transitions in and out of low-power states. For diagnostic purposes, it
|
||||||
|
may be useful to **temporarily** disable EEE to determine if it is
|
||||||
|
contributing to link instability. This is **not a generic recommendation**
|
||||||
|
for disabling power management.
|
||||||
|
|
||||||
|
- **Next Steps**: Disable EEE and monitor if the link becomes stable. If
|
||||||
|
disabling EEE resolves the issue, report the bug so that the driver can be
|
||||||
|
fixed.
|
||||||
|
|
||||||
|
- **Command:**
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
ethtool --set-eee <interface> eee off
|
||||||
|
|
||||||
|
- **Important**: If disabling EEE resolves the instability, the issue should
|
||||||
|
be reported to the maintainers as a bug, and the driver should be corrected
|
||||||
|
to handle EEE properly without causing instability. Disabling EEE
|
||||||
|
permanently should not be seen as a solution.
|
||||||
|
|
||||||
|
- **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.
|
||||||
|
|
||||||
|
- **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.,
|
||||||
|
excessive CRC errors), but results can vary significantly depending on the
|
||||||
|
PHY.
|
||||||
|
|
||||||
|
- **Command:** `ethtool -S <interface>`
|
||||||
|
|
||||||
|
- **Example Output (if supported)**:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
rx_crc_errors: 123
|
||||||
|
tx_errors: 45
|
||||||
|
rx_frame_errors: 78
|
||||||
|
|
||||||
|
- **Note**: If no meaningful error counters are available or if counters are
|
||||||
|
not supported, you may need to rely on physical inspections (e.g., cable
|
||||||
|
condition) or kernel log messages (e.g., link up/down events) to further
|
||||||
|
diagnose the issue.
|
||||||
|
|
||||||
|
When All Else Fails...
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
So you've checked the cables, monitored the logs, disabled EEE, and still...
|
||||||
|
nothing? Don’t worry, you’re not alone. Sometimes, Ethernet gremlins just don’t
|
||||||
|
want to cooperate.
|
||||||
|
|
||||||
|
But before you throw in the towel (or the Ethernet cable), take a deep breath.
|
||||||
|
It’s always possible that:
|
||||||
|
|
||||||
|
1. Your PHY has a unique, undocumented personality.
|
||||||
|
|
||||||
|
2. The problem is lying dormant, waiting for just the right moment to magically
|
||||||
|
resolve itself (hey, it happens!).
|
||||||
|
|
||||||
|
3. Or, it could be that the ultimate solution simply hasn’t been invented yet.
|
||||||
|
|
||||||
|
If none of the above bring you comfort, there’s one final step: contribute! If
|
||||||
|
you've uncovered new or unusual issues, or have creative diagnostic methods,
|
||||||
|
feel free to share your findings and extend this documentation. Together, we
|
||||||
|
can hunt down every elusive network issue - one twisted pair at a time.
|
||||||
|
|
||||||
|
Remember: sometimes the solution is just a reboot away, but if not, it’s time to
|
||||||
|
dig deeper - or report that bug!

|
||||||
|
|
||||||
|
The above parameters can also be set on a per-NAPI basis using netlink via
|
||||||
|
netdev-genl. When used with netlink and configured on a per-NAPI basis, the
|
||||||
|
parameters mentioned above use hyphens instead of underscores:
|
||||||
|
``gro-flush-timeout`` and ``napi-defer-hard-irqs``.
|
||||||
|
|
||||||
|
Per-NAPI configuration can be done programmatically in a user application
|
||||||
|
or by using a script included in the kernel source tree:
|
||||||
|
``tools/net/ynl/cli.py``.
|
||||||
|
|
||||||
|
For example, using the script:
|
||||||
|
|
||||||
|
.. code-block:: bash
|
||||||
|
|
||||||
|
$ kernel-source/tools/net/ynl/cli.py \
|
||||||
|
--spec Documentation/netlink/specs/netdev.yaml \
|
||||||
|

|
||||||
|
--json='{"id": 345,
|
||||||
|
"defer-hard-irqs": 111,
|
||||||
|
"gro-flush-timeout": 11111}'
|
||||||
|
|
||||||
|
Similarly, the parameter ``irq-suspend-timeout`` can be set using netlink
|
||||||
|
via netdev-genl. There is no global sysfs parameter for this value.
|
||||||
|
|
||||||
|
``irq-suspend-timeout`` is used to determine how long an application can
|
||||||
|
completely suspend IRQs. It is used in combination with SO_PREFER_BUSY_POLL,
|
||||||
|
which can be set on a per-epoll context basis with ``EPIOCSPARAMS`` ioctl.

epoll-based busy polling
|
||||||
|
------------------------
|
||||||
|
|
||||||
|
It is possible to trigger packet processing directly from calls to
|
||||||
|
``epoll_wait``. In order to use this feature, a user application must ensure
|
||||||
|
all file descriptors which are added to an epoll context have the same NAPI ID.
|
||||||
|
|
||||||
|
If the application uses a dedicated acceptor thread, the application can obtain
|
||||||
|
the NAPI ID of the incoming connection using SO_INCOMING_NAPI_ID and then
|
||||||
|
distribute that file descriptor to a worker thread. The worker thread would add
|
||||||
|
the file descriptor to its epoll context. This would ensure each worker thread
|
||||||
|
has an epoll context with FDs that have the same NAPI ID.
|
||||||
|
|
||||||
|
Alternatively, if the application uses SO_REUSEPORT, a bpf or ebpf program can
|
||||||
|
be inserted to distribute incoming connections to threads such that each thread
|
||||||
|
is only given incoming connections with the same NAPI ID. Care must be taken to
|
||||||
|
carefully handle cases where a system may have multiple NICs.
|
||||||
|
|
||||||
|
In order to enable busy polling, there are two choices:
|
||||||
|
|
||||||
|
1. ``/proc/sys/net/core/busy_poll`` can be set with a time in useconds to busy
|
||||||
|
loop waiting for events. This is a system-wide setting and will cause all
|
||||||
|
epoll-based applications to busy poll when they call epoll_wait. This may
|
||||||
|
not be desirable as many applications may not have the need to busy poll.
|
||||||
|
|
||||||
|
2. Applications using recent kernels can issue an ioctl on the epoll context
|
||||||
|
file descriptor to set (``EPIOCSPARAMS``) or get (``EPIOCGPARAMS``) ``struct
|
||||||
|
epoll_params``:, which user programs can define as follows:
|
||||||
|
|
||||||
|
.. code-block:: c
|
||||||
|
|
||||||
|
struct epoll_params {
|
||||||
|
uint32_t busy_poll_usecs;
|
||||||
|

will defer IRQs to allow for better batch processing, but will induce latency

when the system is not fully loaded. Choosing a small value for
|
||||||
|
``gro_flush_timeout`` can cause interference of the user application which is
|
||||||
|
attempting to busy poll by device IRQs and softirq processing. This value
|
||||||
|
should be chosen carefully with these tradeoffs in mind. epoll-based busy
|
||||||
|
polling applications may be able to mitigate how much user processing happens
|
||||||
|
by choosing an appropriate value for ``maxevents``.
|
||||||
|
|
||||||
|
Users may want to consider an alternate approach, IRQ suspension, to help deal
|
||||||
|
with these tradeoffs.
|
||||||
|
|
||||||
|
IRQ suspension
|
||||||
|
--------------
|
||||||
|
|
||||||
|
IRQ suspension is a mechanism wherein device IRQs are masked while epoll
|
||||||
|
triggers NAPI packet processing.
|
||||||
|
|
||||||
|
While application calls to epoll_wait successfully retrieve events, the kernel will
|
||||||
|
defer the IRQ suspension timer. If the kernel does not retrieve any events
|
||||||
|
while busy polling (for example, because network traffic levels subsided), IRQ
|
||||||
|
suspension is disabled and the IRQ mitigation strategies described above are
|
||||||
|
engaged.
|
||||||
|
|
||||||
|
This allows users to balance CPU consumption with network processing
|
||||||
|
efficiency.
|
||||||
|
|
||||||
|
To use this mechanism:
|
||||||
|
|
||||||
|
1. The per-NAPI config parameter ``irq-suspend-timeout`` should be set to the
|
||||||
|
maximum time (in nanoseconds) the application can have its IRQs
|
||||||
|
suspended. This is done using netlink, as described above. This timeout
|
||||||
|
serves as a safety mechanism to restart IRQ driver interrupt processing if
|
||||||
|
the application has stalled. This value should be chosen so that it covers
|
||||||
|
the amount of time the user application needs to process data from its
|
||||||
|
call to epoll_wait, noting that applications can control how much data
|
||||||
|
they retrieve by setting ``max_events`` when calling epoll_wait.
|
||||||
|
|
||||||
|
2. The sysfs parameter or per-NAPI config parameters ``gro_flush_timeout``
|
||||||
|
and ``napi_defer_hard_irqs`` can be set to low values. They will be used
|
||||||
|
to defer IRQs after busy poll has found no data.
|
||||||
|
|
||||||
|
3. The ``prefer_busy_poll`` flag must be set to true. This can be done using
|
||||||
|
the ``EPIOCSPARAMS`` ioctl as described above.
|
||||||
|
|
||||||
|
4. The application uses epoll as described above to trigger NAPI packet
|
||||||
|
processing.
|
||||||
|
|
||||||
|
As mentioned above, as long as subsequent calls to epoll_wait return events to
|
||||||
|
userland, the ``irq-suspend-timeout`` is deferred and IRQs are disabled. This
|
||||||
|
allows the application to process data without interference.
|
||||||
|
|
||||||
|
Once a call to epoll_wait results in no events being found, IRQ suspension is
|
||||||
|
automatically disabled and the ``gro_flush_timeout`` and
|
||||||
|
``napi_defer_hard_irqs`` mitigation mechanisms take over.
|
||||||
|
|
||||||
|
It is expected that ``irq-suspend-timeout`` will be set to a value much larger
|
||||||
|
than ``gro_flush_timeout`` as ``irq-suspend-timeout`` should suspend IRQs for
|
||||||
|
the duration of one userland processing cycle.
|
||||||
|
|
||||||
|
While it is not stricly necessary to use ``napi_defer_hard_irqs`` and
|
||||||
|
``gro_flush_timeout`` to use IRQ suspension, their use is strongly
|
||||||
|
recommended.
|
||||||
|
|
||||||
|
IRQ suspension causes the system to alternate between polling mode and
|
||||||
|
irq-driven packet delivery. During busy periods, ``irq-suspend-timeout``
|
||||||
|
overrides ``gro_flush_timeout`` and keeps the system busy polling, but when
|
||||||
|
epoll finds no events, the setting of ``gro_flush_timeout`` and
|
||||||
|
``napi_defer_hard_irqs`` determine the next step.
|
||||||
|
|
||||||
|
There are essentially three possible loops for network processing and
|
||||||
|
packet delivery:
|
||||||
|
|
||||||
|
1) hardirq -> softirq -> napi poll; basic interrupt delivery
|
||||||
|
2) timer -> softirq -> napi poll; deferred irq processing
|
||||||
|
3) epoll -> busy-poll -> napi poll; busy looping
|
||||||
|
|
||||||
|
Loop 2 can take control from Loop 1, if ``gro_flush_timeout`` and
|
||||||
|
``napi_defer_hard_irqs`` are set.
|
||||||
|
|
||||||
|
If ``gro_flush_timeout`` and ``napi_defer_hard_irqs`` are set, Loops 2
|
||||||
|
and 3 "wrestle" with each other for control.
|
||||||
|
|
||||||
|
During busy periods, ``irq-suspend-timeout`` is used as timer in Loop 2,
|
||||||
|
which essentially tilts network processing in favour of Loop 3.
|
||||||
|
|
||||||
|
If ``gro_flush_timeout`` and ``napi_defer_hard_irqs`` are not set, Loop 3
|
||||||
|
cannot take control from Loop 1.
|
||||||
|
|
||||||
|
Therefore, setting ``gro_flush_timeout`` and ``napi_defer_hard_irqs`` is
|
||||||
|
the recommended usage, because otherwise setting ``irq-suspend-timeout``
|
||||||
|
might not have any discernible effect.
