Netlink interface for ethtool
|
|
=============================
|
|
|
|
|
|
Basic information
|
|
=================
|
|
|
|
Netlink interface for ethtool uses generic netlink family ``ethtool``
|
|
(userspace application should use macros ``ETHTOOL_GENL_NAME`` and
|
|
``ETHTOOL_GENL_VERSION`` defined in ``<linux/ethtool_netlink.h>`` uapi
|
|
header). This family does not use a specific header, all information in
|
|
requests and replies is passed using netlink attributes.
|
|
|
|
The ethtool netlink interface uses extended ACK for error and warning
|
|
reporting, userspace application developers are encouraged to make these
|
|
messages available to user in a suitable way.
|
|
|
|
Requests can be divided into three categories: "get" (retrieving information),
|
|
"set" (setting parameters) and "action" (invoking an action).
|
|
|
|
All "set" and "action" type requests require admin privileges
|
|
(``CAP_NET_ADMIN`` in the namespace). Most "get" type requests are allowed for
|
|
anyone but there are exceptions (where the response contains sensitive
|
|
information). In some cases, the request as such is allowed for anyone but
|
|
unprivileged users have attributes with sensitive information (e.g.
|
|
wake-on-lan password) omitted.
|
|
|
|
|
|
Conventions
|
|
===========
|
|
|
|
Attributes which represent a boolean value usually use NLA_U8 type so that we
|
|
can distinguish three states: "on", "off" and "not present" (meaning the
|
|
information is not available in "get" requests or value is not to be changed
|
|
in "set" requests). For these attributes, the "true" value should be passed as
|
|
number 1 but any non-zero value should be understood as "true" by recipient.
|
|
In the tables below, "bool" denotes NLA_U8 attributes interpreted in this way.
|
|
|
|
In the message structure descriptions below, if an attribute name is suffixed
|
|
with "+", parent nest can contain multiple attributes of the same type. This
|
|
implements an array of entries.
|
|
|
|
|
|
Request header
|
|
==============
|
|
|
|
Each request or reply message contains a nested attribute with common header.
|
|
Structure of this header is
|
|
|
|
============================== ====== =============================
|
|
``ETHTOOL_A_HEADER_DEV_INDEX`` u32 device ifindex
|
|
``ETHTOOL_A_HEADER_DEV_NAME`` string device name
|
|
``ETHTOOL_A_HEADER_FLAGS`` u32 flags common for all requests
|
|
============================== ====== =============================
|
|
|
|
``ETHTOOL_A_HEADER_DEV_INDEX`` and ``ETHTOOL_A_HEADER_DEV_NAME`` identify the
|
|
device message relates to. One of them is sufficient in requests, if both are
|
|
used, they must identify the same device. Some requests, e.g. global string
|
|
sets, do not require device identification. Most ``GET`` requests also allow
|
|
dump requests without device identification to query the same information for
|
|
all devices providing it (each device in a separate message).
|
|
|
|
``ETHTOOL_A_HEADER_FLAGS`` is a bitmap of request flags common for all request
|
|
types. The interpretation of these flags is the same for all request types but
|
|
the flags may not apply to requests. Recognized flags are:
|
|
|
|
================================= ===================================
|
|
``ETHTOOL_FLAG_COMPACT_BITSETS`` use compact format bitsets in reply
|
|
``ETHTOOL_FLAG_OMIT_REPLY`` omit optional reply (_SET and _ACT)
|
|
================================= ===================================
|
|
|
|
New request flags should follow the general idea that if the flag is not set,
|
|
the behaviour is backward compatible, i.e. requests from old clients not aware
|
|
of the flag should be interpreted the way the client expects. A client must
|
|
not set flags it does not understand.
|
|
|
|
|
|
Bit sets
|
|
========
|
|
|
|
For short bitmaps of (reasonably) fixed length, standard ``NLA_BITFIELD32``
|
|
type is used. For arbitrary length bitmaps, ethtool netlink uses a nested
|
|
attribute with contents of one of two forms: compact (two binary bitmaps
|
|
representing bit values and mask of affected bits) and bit-by-bit (list of
|
|
bits identified by either index or name).
|
|
|
|
Verbose (bit-by-bit) bitsets allow sending symbolic names for bits together
|
|
with their values which saves a round trip (when the bitset is passed in a
|
|
request) or at least a second request (when the bitset is in a reply). This is
|
|
useful for one shot applications like traditional ethtool command. On the
|
|
other hand, long running applications like ethtool monitor (displaying
|
|
notifications) or network management daemons may prefer fetching the names
|
|
only once and using compact form to save message size. Notifications from
|
|
ethtool netlink interface always use compact form for bitsets.
|
|
|
|
A bitset can represent either a value/mask pair (``ETHTOOL_A_BITSET_NOMASK``
|
|
not set) or a single bitmap (``ETHTOOL_A_BITSET_NOMASK`` set). In requests
|
|
modifying a bitmap, the former changes the bit set in mask to values set in
|
|
value and preserves the rest; the latter sets the bits set in the bitmap and
|
|
clears the rest.
|
|
|
|
Compact form: nested (bitset) atrribute contents:
|
|
|
|
============================ ====== ============================
|
|
``ETHTOOL_A_BITSET_NOMASK`` flag no mask, only a list
|
|
``ETHTOOL_A_BITSET_SIZE`` u32 number of significant bits
|
|
``ETHTOOL_A_BITSET_VALUE`` binary bitmap of bit values
|
|
``ETHTOOL_A_BITSET_MASK`` binary bitmap of valid bits
|
|
============================ ====== ============================
|
|
|
|
Value and mask must have length at least ``ETHTOOL_A_BITSET_SIZE`` bits
|
|
rounded up to a multiple of 32 bits. They consist of 32-bit words in host byte
|
|
order, words ordered from least significant to most significant (i.e. the same
|
|
way as bitmaps are passed with ioctl interface).
|
|
|
|
For compact form, ``ETHTOOL_A_BITSET_SIZE`` and ``ETHTOOL_A_BITSET_VALUE`` are
|
|
mandatory. ``ETHTOOL_A_BITSET_MASK`` attribute is mandatory if
|
|
``ETHTOOL_A_BITSET_NOMASK`` is not set (bitset represents a value/mask pair);
|
|
if ``ETHTOOL_A_BITSET_NOMASK`` is not set, ``ETHTOOL_A_BITSET_MASK`` is not
|
|
allowed (bitset represents a single bitmap.
|
|
|
|
Kernel bit set length may differ from userspace length if older application is
|
|
used on newer kernel or vice versa. If userspace bitmap is longer, an error is
|
|
issued only if the request actually tries to set values of some bits not
|
|
recognized by kernel.
|
|
|
|
Bit-by-bit form: nested (bitset) attribute contents:
|
|
|
|
+------------------------------------+--------+-----------------------------+
|
|
| ``ETHTOOL_A_BITSET_NOMASK`` | flag | no mask, only a list |
|
|
+------------------------------------+--------+-----------------------------+
|
|
| ``ETHTOOL_A_BITSET_SIZE`` | u32 | number of significant bits |
|
|
+------------------------------------+--------+-----------------------------+
|
|
| ``ETHTOOL_A_BITSET_BITS`` | nested | array of bits |
|
|
+-+----------------------------------+--------+-----------------------------+
|
|
| | ``ETHTOOL_A_BITSET_BITS_BIT+`` | nested | one bit |
|
|
+-+-+--------------------------------+--------+-----------------------------+
|
|
| | | ``ETHTOOL_A_BITSET_BIT_INDEX`` | u32 | bit index (0 for LSB) |
|
|
+-+-+--------------------------------+--------+-----------------------------+
|
|
| | | ``ETHTOOL_A_BITSET_BIT_NAME`` | string | bit name |
|
|
+-+-+--------------------------------+--------+-----------------------------+
|
|
| | | ``ETHTOOL_A_BITSET_BIT_VALUE`` | flag | present if bit is set |
|
|
+-+-+--------------------------------+--------+-----------------------------+
|
|
|
|
Bit size is optional for bit-by-bit form. ``ETHTOOL_A_BITSET_BITS`` nest can
|
|
only contain ``ETHTOOL_A_BITSET_BITS_BIT`` attributes but there can be an
|
|
arbitrary number of them. A bit may be identified by its index or by its
|
|
name. When used in requests, listed bits are set to 0 or 1 according to
|
|
``ETHTOOL_A_BITSET_BIT_VALUE``, the rest is preserved. A request fails if
|
|
index exceeds kernel bit length or if name is not recognized.
|
|
|
|
When ``ETHTOOL_A_BITSET_NOMASK`` flag is present, bitset is interpreted as
|
|
a simple bitmap. ``ETHTOOL_A_BITSET_BIT_VALUE`` attributes are not used in
|
|
such case. Such bitset represents a bitmap with listed bits set and the rest
|
|
zero.
|
|
|
|
In requests, application can use either form. Form used by kernel in reply is
|
|
determined by ``ETHTOOL_FLAG_COMPACT_BITSETS`` flag in flags field of request
|
|
header. Semantics of value and mask depends on the attribute.
|
|
|
|
|
|
List of message types

|
|
|
|
All constants identifying message types use ``ETHTOOL_CMD_`` prefix and suffix
|
|

|
|
``GET`` requests are sent by userspace applications to retrieve device
|
|
information. They usually do not contain any message specific attributes.
|
|
Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET``
|
|
request with ``NLM_F_DUMP`` and no device identification can be used to query
|
|
the information for all devices supporting the request.
|
|
|
|
If the data can be also modified, corresponding ``SET`` message with the same
|
|
layout as corresponding ``GET_REPLY`` is used to request changes. Only
|
|
attributes where a change is requested are included in such request (also, not
|
|
all attributes may be changed). Replies to most ``SET`` request consist only
|
|
of error code and extack; if kernel provides additional data, it is sent in
|
|
the form of corresponding ``SET_REPLY`` message which can be suppressed by
|
|
setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header.
|
|
|
|
Data modification also triggers sending a ``NTF`` message with a notification.
|
|
These usually bear only a subset of attributes which was affected by the
|
|
change. The same notification is issued if the data is modified using other
|
|
means (mostly ioctl ethtool interface). Unlike notifications from ethtool
|
|
netlink code which are only sent if something actually changed, notifications
|
|
triggered by ioctl interface may be sent even if the request did not actually
|
|
change any data.
|
|
|
|
``ACT`` messages request kernel (driver) to perform a specific action. If some
|
|
information is reported by kernel (which can be suppressed by setting
|
|
``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of
|
|
an ``ACT_REPLY`` message. Performing an action also triggers a notification
|
|
(``NTF`` message).
|
|
|
|
Later sections describe the format and semantics of these messages.
|
|
|
|
|
|
STRSET_GET
|
|
==========
|
|
|
|
Requests contents of a string set as provided by ioctl commands
|
|
``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user
|
|
writeable so that the corresponding ``STRSET_SET`` message is only used in
|
|
kernel replies. There are two types of string sets: global (independent of
|
|
a device, e.g. device feature names) and device specific (e.g. device private
|
|
flags).
|
|
|
|
Request contents:

+---------------------------------------+--------+-----------------------+
|
|
|
|
Device identification in request header is optional. Depending on its presence
|
|
a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests:
|
|
|
|
- no ``NLM_F_DUMP,`` no device: get "global" stringsets
|
|
- no ``NLM_F_DUMP``, with device: get string sets related to the device
|
|
- ``NLM_F_DUMP``, no device: get device related string sets for all devices
|
|
|
|
If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of
|
|
requested type are returned, otherwise only those specified in the request.
|
|
Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string
|
|
counts of the sets, not the actual strings.

|
|
of speed and duplex is specified, kernel adjusts advertised modes to all
|
|
supported modes matching speed, duplex or both (whatever is specified). This
|
|
autoselection is done on ethtool side with ioctl interface, netlink interface
|
|
is supposed to allow requesting changes without knowing what exactly kernel
|
|
supports.

LINKSTATE_GET
|
|
=============
|
|
|
|
Requests link state information. Link up/down flag (as provided by
|
|
``ETHTOOL_GLINK`` ioctl command) is provided. Optionally, extended state might
|
|
be provided as well. In general, extended state describes reasons for why a port
|
|
is down, or why it operates in some non-obvious mode. This request does not have
|
|
any attributes.

|
carrier flag provided by ``netif_carrier_ok()`` but there are drivers which
|
|
define their own handler.
|
|
|
|
``ETHTOOL_A_LINKSTATE_EXT_STATE`` and ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE`` are
|
|
optional values. ethtool core can provide either both
|
|
``ETHTOOL_A_LINKSTATE_EXT_STATE`` and ``ETHTOOL_A_LINKSTATE_EXT_SUBSTATE``,
|
|
or only ``ETHTOOL_A_LINKSTATE_EXT_STATE``, or none of them.
|

DEBUG_GET
|
|
=========
|
|
|
|

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

``ETHTOOL_A_DEBUG_HEADER`` nested reply header
|
|
``ETHTOOL_A_DEBUG_MSGMASK`` bitset message mask
|
|
==================================== ====== ==========================
|
|
|
|
The message mask (``ETHTOOL_A_DEBUG_MSGMASK``) is equal to message level as
|
|
provided by ``ETHTOOL_GMSGLVL`` and set by ``ETHTOOL_SMSGLVL`` in ioctl
|
|
interface. While it is called message level there for historical reasons, most
|
|
drivers and almost all newer drivers use it as a mask of enabled message
|
|
classes (represented by ``NETIF_MSG_*`` constants); therefore netlink
|
|
interface follows its actual use in practice.
|
|
|
|
``DEBUG_GET`` allows dump requests (kernel returns reply messages for all
|
|
devices supporting the request).
|
|
|
|
|
|
DEBUG_SET
|

WOL_GET
|
|
=======
|
|
|
|
Query device wake-on-lan settings. Unlike most "GET" type requests,
|
|
``ETHTOOL_MSG_WOL_GET`` requires (netns) ``CAP_NET_ADMIN`` privileges as it
|
|
(potentially) provides SecureOn(tm) password which is confidential.
|
|
|

|
|
``ETHTOOL_A_WOL_SOPASS`` binary SecureOn(tm) password
|
|
==================================== ====== ==========================
|
|
|
|
In reply, ``ETHTOOL_A_WOL_MODES`` mask consists of modes supported by the
|
|
device, value of modes which are enabled. ``ETHTOOL_A_WOL_SOPASS`` is only
|
|
included in reply if ``WAKE_MAGICSECURE`` mode is supported.
|
|
|
|
|
|
WOL_SET
|
|
=======
|
|
|
|
Set or update wake-on-lan settings.

``ETHTOOL_A_WOL_SOPASS`` binary SecureOn(tm) password
|
|
==================================== ====== ==========================
|
|
|
|
``ETHTOOL_A_WOL_SOPASS`` is only allowed for devices supporting
|
|
``WAKE_MAGICSECURE`` mode.
|
|
|
|
|
|
FEATURES_GET
|
|
============
|
|
|
|
Gets netdev features like ``ETHTOOL_GFEATURES`` ioctl request.
|
|
|

|
|
``ETHTOOL_A_FEATURES_ACTIVE`` bitset dev->features
|
|
``ETHTOOL_A_FEATURES_NOCHANGE`` bitset NETIF_F_NEVER_CHANGE
|
|
==================================== ====== ==========================
|
|
|
|
Bitmaps in kernel response have the same meaning as bitmaps used in ioctl
|
|
interference but attribute names are different (they are based on
|
|
corresponding members of struct net_device). Legacy "flags" are not provided,
|
|
if userspace needs them (most likely only ethtool for backward compatibility),
|
|
it can calculate their values from related feature bits itself.
|
|
ETHA_FEATURES_HW uses mask consisting of all features recognized by kernel (to
|
|
provide all names when using verbose bitmap format), the other three use no
|
|
mask (simple bit lists).
|
|
|
|
|
|
FEATURES_SET
|
|
============
|
|
|
|
Request to set netdev features like ``ETHTOOL_SFEATURES`` ioctl request.
|
|
|
|
Request contents:
|
|
|
|
==================================== ====== ==========================
|
|
``ETHTOOL_A_FEATURES_HEADER`` nested request header

==================================== ====== ==========================
|
|
|
|
Kernel response contents:
|
|
|
|
==================================== ====== ==========================
|
|
``ETHTOOL_A_FEATURES_HEADER`` nested reply header
|
|
``ETHTOOL_A_FEATURES_WANTED`` bitset diff wanted vs. result
|
|
``ETHTOOL_A_FEATURES_ACTIVE`` bitset diff old vs. new active
|
|
==================================== ====== ==========================
|
|
|
|
Request constains only one bitset which can be either value/mask pair (request
|
|
to change specific feature bits and leave the rest) or only a value (request
|
|
to set all features to specified set).
|
|
|
|
As request is subject to netdev_change_features() sanity checks, optional
|
|
kernel reply (can be suppressed by ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request
|
|
header) informs client about the actual result. ``ETHTOOL_A_FEATURES_WANTED``
|
|
reports the difference between client request and actual result: mask consists
|
|
of bits which differ between requested features and result (dev->features
|
|
after the operation), value consists of values of these bits in the request
|
|
(i.e. negated values from resulting features). ``ETHTOOL_A_FEATURES_ACTIVE``
|
|
reports the difference between old and new dev->features: mask consists of
|
|
bits which have changed, values are their values in new dev->features (after
|
|
the operation).
|
|
|
|
``ETHTOOL_MSG_FEATURES_NTF`` notification is sent not only if device features
|
|
are modified using ``ETHTOOL_MSG_FEATURES_SET`` request or on of ethtool ioctl
|
|
request but also each time features are modified with netdev_update_features()
|
|
or netdev_change_features().
|
|
|
|
|
|
PRIVFLAGS_GET
|
|
=============

``ETHTOOL_A_PRIVFLAGS_HEADER`` nested reply header
|
|
``ETHTOOL_A_PRIVFLAGS_FLAGS`` bitset private flags
|
|
==================================== ====== ==========================
|
|
|
|
``ETHTOOL_A_PRIVFLAGS_FLAGS`` is a bitset with values of device private flags.
|
|
These flags are defined by driver, their number and names (and also meaning)
|
|
are device dependent. For compact bitset format, names can be retrieved as
|
|
``ETH_SS_PRIV_FLAGS`` string set. If verbose bitset format is requested,
|
|
response uses all private flags supported by the device as mask so that client
|
|
gets the full information without having to fetch the string set with names.
|
|
|
|
|
|
PRIVFLAGS_SET
|
|
=============
|
|
|
|
Sets or modifies values of device private flags like ``ETHTOOL_SPFLAGS``

|
|
==================================== ====== ==========================
|
|
|
|
``ETHTOOL_A_PRIVFLAGS_FLAGS`` can either set the whole set of private flags or
|
|
modify only values of some of them.
|
|
|
|
|

In ``ETHTOOL_A_EEE_MODES_OURS``, mask consists of link modes for which EEE is
|
|
enabled, value of link modes for which EEE is advertised. Link modes for which
|
|
peer advertises EEE are listed in ``ETHTOOL_A_EEE_MODES_PEER`` (no mask). The
|
|
netlink interface allows reporting EEE status for all link modes but only
|

``ETHTOOL_A_EEE_MODES_OURS`` is used to either list link modes to advertise
|
|
EEE for (if there is no mask) or specify changes to the list (if there is
|
|
a mask). The netlink interface allows reporting EEE status for all link modes
|
|
but only first 32 can be set at the moment as that is what the ``ethtool_ops``
|
|
callback supports.

Notification contents:
|
|
|
|
An Ethernet cable typically contains 1, 2 or 4 pairs. The length of
|
|
the pair can only be measured when there is a fault in the pair and
|
|
hence a reflection. Information about the fault may not be available,
|
|
depending on the specific hardware. Hence the contents of the notify
|
|
message are mostly optional. The attributes can be repeated an
|
|
arbitrary number of times, in an arbitrary order, for an arbitrary
|
|
number of pairs.
|
|
|
|
The example shows the notification sent when the test is completed for
|
|
a T2 cable, i.e. two pairs. One pair is OK and hence has no length
|
|
information. The second pair has a fault and does have length
|
|
information.

| | ``ETHTOOL_A_CABLE_TEST_TDR_CFG_PAIR`` | u8 | pair to test |
|
|
+-+-+----------------------------------------+--------+-----------------------+
|
|
|
|
The ETHTOOL_A_CABLE_TEST_TDR_CFG is optional, as well as all members
|
|
of the nest. All distances are expressed in centimeters. The PHY takes
|
|
the distances as a guide, and rounds to the nearest distance it
|
|
actually supports. If a pair is passed, only that one pair will be
|
|
tested. Otherwise all pairs are tested.
|
|
|
|
Notification contents:
|
|
|
|
Raw TDR data is gathered by sending a pulse down the cable and
|
|
recording the amplitude of the reflected pulse for a given distance.
|
|
|
|
It can take a number of seconds to collect TDR data, especial if the
|
|
full 100 meters is probed at 1 meter intervals. When the test is
|
|
started a notification will be sent containing just
|
|
ETHTOOL_A_CABLE_TEST_TDR_STATUS with the value
|
|
ETHTOOL_A_CABLE_TEST_NTF_STATUS_STARTED.
|
|
|
|
When the test has completed a second notification will be sent
|
|
containing ETHTOOL_A_CABLE_TEST_TDR_STATUS with the value
|
|
ETHTOOL_A_CABLE_TEST_NTF_STATUS_COMPLETED and the TDR data.
|
|
|
|
The message may optionally contain the amplitude of the pulse send
|
|
down the cable. This is measured in mV. A reflection should not be
|
|
bigger than transmitted pulse.
|
|
|
|
Before the raw TDR data should be an ETHTOOL_A_CABLE_TDR_NEST_STEP
|
|
nest containing information about the distance along the cable for the
|
|
first reading, the last reading, and the step between each
|
|
reading. Distances are measured in centimeters. These should be the
|
|
exact values the PHY used. These may be different to what the user
|
|
requested, if the native measurement resolution is greater than 1 cm.
|
|
|
|
For each step along the cable, a ETHTOOL_A_CABLE_TDR_NEST_AMPLITUDE is
|
|
used to report the amplitude of the reflection for a given pair.
