2Netlink interface for ethtool

6Basic information
7=================
8
9Netlink interface for ethtool uses generic netlink family ``ethtool``
10(userspace application should use macros ``ETHTOOL_GENL_NAME`` and
11``ETHTOOL_GENL_VERSION`` defined in ``<linux/ethtool_netlink.h>`` uapi
12header). This family does not use a specific header, all information in
13requests and replies is passed using netlink attributes.
14
15The ethtool netlink interface uses extended ACK for error and warning
16reporting, userspace application developers are encouraged to make these
17messages available to user in a suitable way.
18
19Requests can be divided into three categories: "get" (retrieving information),
20"set" (setting parameters) and "action" (invoking an action).
21
22All "set" and "action" type requests require admin privileges
23(``CAP_NET_ADMIN`` in the namespace). Most "get" type requests are allowed for
24anyone but there are exceptions (where the response contains sensitive
25information). In some cases, the request as such is allowed for anyone but
26unprivileged users have attributes with sensitive information (e.g.
27wake-on-lan password) omitted.
28
29
30Conventions
31===========
32
33Attributes which represent a boolean value usually use NLA_U8 type so that we
34can distinguish three states: "on", "off" and "not present" (meaning the
35information is not available in "get" requests or value is not to be changed
36in "set" requests). For these attributes, the "true" value should be passed as
37number 1 but any non-zero value should be understood as "true" by recipient.
38In the tables below, "bool" denotes NLA_U8 attributes interpreted in this way.
39
40In the message structure descriptions below, if an attribute name is suffixed
41with "+", parent nest can contain multiple attributes of the same type. This
42implements an array of entries.
43
44
45Request header
46==============
47
48Each request or reply message contains a nested attribute with common header.
49Structure of this header is
50
51  ==============================  ======  =============================
52  ``ETHTOOL_A_HEADER_DEV_INDEX``  u32     device ifindex
53  ``ETHTOOL_A_HEADER_DEV_NAME``   string  device name
54  ``ETHTOOL_A_HEADER_FLAGS``      u32     flags common for all requests
55  ==============================  ======  =============================
56
57``ETHTOOL_A_HEADER_DEV_INDEX`` and ``ETHTOOL_A_HEADER_DEV_NAME`` identify the
58device message relates to. One of them is sufficient in requests, if both are
59used, they must identify the same device. Some requests, e.g. global string
60sets, do not require device identification. Most ``GET`` requests also allow
61dump requests without device identification to query the same information for
62all devices providing it (each device in a separate message).
63
64``ETHTOOL_A_HEADER_FLAGS`` is a bitmap of request flags common for all request
65types. The interpretation of these flags is the same for all request types but
66the flags may not apply to requests. Recognized flags are:
67
68  =================================  ===================================
69  ``ETHTOOL_FLAG_COMPACT_BITSETS``   use compact format bitsets in reply
70  ``ETHTOOL_FLAG_OMIT_REPLY``        omit optional reply (_SET and _ACT)
71  =================================  ===================================
72
73New request flags should follow the general idea that if the flag is not set,
74the behaviour is backward compatible, i.e. requests from old clients not aware
75of the flag should be interpreted the way the client expects. A client must
76not set flags it does not understand.
77
78
79Bit sets
80========
81
82For short bitmaps of (reasonably) fixed length, standard ``NLA_BITFIELD32``
83type is used. For arbitrary length bitmaps, ethtool netlink uses a nested
84attribute with contents of one of two forms: compact (two binary bitmaps
85representing bit values and mask of affected bits) and bit-by-bit (list of
86bits identified by either index or name).
87
88Verbose (bit-by-bit) bitsets allow sending symbolic names for bits together
89with their values which saves a round trip (when the bitset is passed in a
90request) or at least a second request (when the bitset is in a reply). This is
91useful for one shot applications like traditional ethtool command. On the
92other hand, long running applications like ethtool monitor (displaying
93notifications) or network management daemons may prefer fetching the names
94only once and using compact form to save message size. Notifications from
95ethtool netlink interface always use compact form for bitsets.
96
97A bitset can represent either a value/mask pair (``ETHTOOL_A_BITSET_NOMASK``
98not set) or a single bitmap (``ETHTOOL_A_BITSET_NOMASK`` set). In requests
99modifying a bitmap, the former changes the bit set in mask to values set in
100value and preserves the rest; the latter sets the bits set in the bitmap and
101clears the rest.
102
103Compact form: nested (bitset) atrribute contents:
104
105  ============================  ======  ============================
106  ``ETHTOOL_A_BITSET_NOMASK``   flag    no mask, only a list
107  ``ETHTOOL_A_BITSET_SIZE``     u32     number of significant bits
108  ``ETHTOOL_A_BITSET_VALUE``    binary  bitmap of bit values
109  ``ETHTOOL_A_BITSET_MASK``     binary  bitmap of valid bits
110  ============================  ======  ============================
111
112Value and mask must have length at least ``ETHTOOL_A_BITSET_SIZE`` bits
113rounded up to a multiple of 32 bits. They consist of 32-bit words in host byte
114order, words ordered from least significant to most significant (i.e. the same
115way as bitmaps are passed with ioctl interface).
116
117For compact form, ``ETHTOOL_A_BITSET_SIZE`` and ``ETHTOOL_A_BITSET_VALUE`` are
118mandatory. ``ETHTOOL_A_BITSET_MASK`` attribute is mandatory if
119``ETHTOOL_A_BITSET_NOMASK`` is not set (bitset represents a value/mask pair);
120if ``ETHTOOL_A_BITSET_NOMASK`` is not set, ``ETHTOOL_A_BITSET_MASK`` is not
121allowed (bitset represents a single bitmap.
122
123Kernel bit set length may differ from userspace length if older application is
124used on newer kernel or vice versa. If userspace bitmap is longer, an error is
125issued only if the request actually tries to set values of some bits not
126recognized by kernel.
127
128Bit-by-bit form: nested (bitset) attribute contents:
129
130 +------------------------------------+--------+-----------------------------+
131 | ``ETHTOOL_A_BITSET_NOMASK``        | flag   | no mask, only a list        |
132 +------------------------------------+--------+-----------------------------+
133 | ``ETHTOOL_A_BITSET_SIZE``          | u32    | number of significant bits  |
134 +------------------------------------+--------+-----------------------------+
135 | ``ETHTOOL_A_BITSET_BITS``          | nested | array of bits               |
136 +-+----------------------------------+--------+-----------------------------+
137 | | ``ETHTOOL_A_BITSET_BITS_BIT+``   | nested | one bit                     |
138 +-+-+--------------------------------+--------+-----------------------------+
139 | | | ``ETHTOOL_A_BITSET_BIT_INDEX`` | u32    | bit index (0 for LSB)       |
140 +-+-+--------------------------------+--------+-----------------------------+
141 | | | ``ETHTOOL_A_BITSET_BIT_NAME``  | string | bit name                    |
142 +-+-+--------------------------------+--------+-----------------------------+
143 | | | ``ETHTOOL_A_BITSET_BIT_VALUE`` | flag   | present if bit is set       |
144 +-+-+--------------------------------+--------+-----------------------------+
145
146Bit size is optional for bit-by-bit form. ``ETHTOOL_A_BITSET_BITS`` nest can
147only contain ``ETHTOOL_A_BITSET_BITS_BIT`` attributes but there can be an
148arbitrary number of them.  A bit may be identified by its index or by its
149name. When used in requests, listed bits are set to 0 or 1 according to
150``ETHTOOL_A_BITSET_BIT_VALUE``, the rest is preserved. A request fails if
151index exceeds kernel bit length or if name is not recognized.
152
153When ``ETHTOOL_A_BITSET_NOMASK`` flag is present, bitset is interpreted as
154a simple bitmap. ``ETHTOOL_A_BITSET_BIT_VALUE`` attributes are not used in
155such case. Such bitset represents a bitmap with listed bits set and the rest
156zero.
157
158In requests, application can use either form. Form used by kernel in reply is
159determined by ``ETHTOOL_FLAG_COMPACT_BITSETS`` flag in flags field of request
160header. Semantics of value and mask depends on the attribute.
161
162
163List of message types
164=====================
165
166All constants identifying message types use ``ETHTOOL_CMD_`` prefix and suffix
167according to message purpose:
168
169  ==============    ======================================
170  ``_GET``          userspace request to retrieve data
171  ``_SET``          userspace request to set data
172  ``_ACT``          userspace request to perform an action
173  ``_GET_REPLY``    kernel reply to a ``GET`` request
174  ``_SET_REPLY``    kernel reply to a ``SET`` request
175  ``_ACT_REPLY``    kernel reply to an ``ACT`` request
176  ``_NTF``          kernel notification
177  ==============    ======================================
178
179Userspace to kernel:
180
181  ===================================== ================================
182  ``ETHTOOL_MSG_STRSET_GET``            get string set
183  ``ETHTOOL_MSG_LINKINFO_GET``          get link settings
184  ``ETHTOOL_MSG_LINKINFO_SET``          set link settings
185  ``ETHTOOL_MSG_LINKMODES_GET``         get link modes info
186  ``ETHTOOL_MSG_LINKMODES_SET``         set link modes info
187  ``ETHTOOL_MSG_LINKSTATE_GET``         get link state
188  ``ETHTOOL_MSG_DEBUG_GET``             get debugging settings
189  ``ETHTOOL_MSG_DEBUG_SET``             set debugging settings
190  ``ETHTOOL_MSG_WOL_GET``               get wake-on-lan settings
191  ``ETHTOOL_MSG_WOL_SET``               set wake-on-lan settings
192  ===================================== ================================
193
194Kernel to userspace:
195
196  ===================================== =================================
197  ``ETHTOOL_MSG_STRSET_GET_REPLY``      string set contents
198  ``ETHTOOL_MSG_LINKINFO_GET_REPLY``    link settings
199  ``ETHTOOL_MSG_LINKINFO_NTF``          link settings notification
200  ``ETHTOOL_MSG_LINKMODES_GET_REPLY``   link modes info
201  ``ETHTOOL_MSG_LINKMODES_NTF``         link modes notification
202  ``ETHTOOL_MSG_LINKSTATE_GET_REPLY``   link state info
203  ``ETHTOOL_MSG_DEBUG_GET_REPLY``       debugging settings
204  ``ETHTOOL_MSG_DEBUG_NTF``             debugging settings notification
205  ``ETHTOOL_MSG_WOL_GET_REPLY``         wake-on-lan settings
206  ``ETHTOOL_MSG_WOL_NTF``               wake-on-lan settings notification
207  ===================================== =================================
208
209``GET`` requests are sent by userspace applications to retrieve device
210information. They usually do not contain any message specific attributes.
211Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET``
212request with ``NLM_F_DUMP`` and no device identification can be used to query
213the information for all devices supporting the request.
214
215If the data can be also modified, corresponding ``SET`` message with the same
216layout as corresponding ``GET_REPLY`` is used to request changes. Only
217attributes where a change is requested are included in such request (also, not
218all attributes may be changed). Replies to most ``SET`` request consist only
219of error code and extack; if kernel provides additional data, it is sent in
220the form of corresponding ``SET_REPLY`` message which can be suppressed by
221setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header.
222
223Data modification also triggers sending a ``NTF`` message with a notification.
224These usually bear only a subset of attributes which was affected by the
225change. The same notification is issued if the data is modified using other
226means (mostly ioctl ethtool interface). Unlike notifications from ethtool
227netlink code which are only sent if something actually changed, notifications
228triggered by ioctl interface may be sent even if the request did not actually
229change any data.
230
231``ACT`` messages request kernel (driver) to perform a specific action. If some
232information is reported by kernel (which can be suppressed by setting
233``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of
234an ``ACT_REPLY`` message. Performing an action also triggers a notification
235(``NTF`` message).
236
237Later sections describe the format and semantics of these messages.
238
239
240STRSET_GET
241==========
242
243Requests contents of a string set as provided by ioctl commands
244``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user
245writeable so that the corresponding ``STRSET_SET`` message is only used in
246kernel replies. There are two types of string sets: global (independent of
247a device, e.g. device feature names) and device specific (e.g. device private
248flags).
249
250Request contents:

284 +---------------------------------------+--------+-----------------------+
285
286Device identification in request header is optional. Depending on its presence
287a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests:
288
289 - no ``NLM_F_DUMP,`` no device: get "global" stringsets
290 - no ``NLM_F_DUMP``, with device: get string sets related to the device
291 - ``NLM_F_DUMP``, no device: get device related string sets for all devices
292
293If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of
294requested type are returned, otherwise only those specified in the request.
295Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string
296counts of the sets, not the actual strings.
297
298
299LINKINFO_GET
300============
301
302Requests link settings as provided by ``ETHTOOL_GLINKSETTINGS`` except for
303link modes and autonegotiation related information. The request does not use
304any attributes.
305
306Request contents:

320  ``ETHTOOL_A_LINKINFO_TRANSCEIVER``    u8      transceiver
321  ====================================  ======  ==========================
322
323Attributes and their values have the same meaning as matching members of the
324corresponding ioctl structures.
325
326``LINKINFO_GET`` allows dump requests (kernel returns reply message for all
327devices supporting the request).
328
329
330LINKINFO_SET
331============
332
333``LINKINFO_SET`` request allows setting some of the attributes reported by
334``LINKINFO_GET``.
335
336Request contents:

342  ``ETHTOOL_A_LINKINFO_TP_MDIX_CTRL``   u8      MDI(-X) control
343  ====================================  ======  ==========================
344
345MDI(-X) status and transceiver cannot be set, request with the corresponding
346attributes is rejected.
347
348
349LINKMODES_GET
350=============
351
352Requests link modes (supported, advertised and peer advertised) and related
353information (autonegotiation status, link speed and duplex) as provided by
354``ETHTOOL_GLINKSETTINGS``. The request does not use any attributes.
355
356Request contents:
357
358  ====================================  ======  ==========================
359  ``ETHTOOL_A_LINKMODES_HEADER``        nested  request header
360  ====================================  ======  ==========================
361
362Kernel response contents:

369  ``ETHTOOL_A_LINKMODES_SPEED``         u32     link speed (Mb/s)
370  ``ETHTOOL_A_LINKMODES_DUPLEX``        u8      duplex mode
371  ====================================  ======  ==========================
372
373For ``ETHTOOL_A_LINKMODES_OURS``, value represents advertised modes and mask
374represents supported modes. ``ETHTOOL_A_LINKMODES_PEER`` in the reply is a bit
375list.
376
377``LINKMODES_GET`` allows dump requests (kernel returns reply messages for all
378devices supporting the request).
379
380
381LINKMODES_SET
382=============
383
384Request contents:
385
386  ====================================  ======  ==========================
387  ``ETHTOOL_A_LINKMODES_HEADER``        nested  request header
388  ``ETHTOOL_A_LINKMODES_AUTONEG``       u8      autonegotiation status
389  ``ETHTOOL_A_LINKMODES_OURS``          bitset  advertised link modes
390  ``ETHTOOL_A_LINKMODES_PEER``          bitset  partner link modes
391  ``ETHTOOL_A_LINKMODES_SPEED``         u32     link speed (Mb/s)
392  ``ETHTOOL_A_LINKMODES_DUPLEX``        u8      duplex mode
393  ====================================  ======  ==========================
394
395``ETHTOOL_A_LINKMODES_OURS`` bit set allows setting advertised link modes. If
396autonegotiation is on (either set now or kept from before), advertised modes
397are not changed (no ``ETHTOOL_A_LINKMODES_OURS`` attribute) and at least one
398of speed and duplex is specified, kernel adjusts advertised modes to all
399supported modes matching speed, duplex or both (whatever is specified). This
400autoselection is done on ethtool side with ioctl interface, netlink interface
401is supposed to allow requesting changes without knowing what exactly kernel
402supports.
403
404
405LINKSTATE_GET
406=============
407
408Requests link state information. At the moment, only link up/down flag (as
409provided by ``ETHTOOL_GLINK`` ioctl command) is provided but some future
410extensions are planned (e.g. link down reason). This request does not have any
411attributes.
412
413Request contents:
414

424  ====================================  ======  ==========================
425
426For most NIC drivers, the value of ``ETHTOOL_A_LINKSTATE_LINK`` returns
427carrier flag provided by ``netif_carrier_ok()`` but there are drivers which
428define their own handler.
429
430``LINKSTATE_GET`` allows dump requests (kernel returns reply messages for all
431devices supporting the request).
432
433
434DEBUG_GET
435=========
436
437Requests debugging settings of a device. At the moment, only message mask is
438provided.

451  ====================================  ======  ==========================
452
453The message mask (``ETHTOOL_A_DEBUG_MSGMASK``) is equal to message level as
454provided by ``ETHTOOL_GMSGLVL`` and set by ``ETHTOOL_SMSGLVL`` in ioctl
455interface. While it is called message level there for historical reasons, most
456drivers and almost all newer drivers use it as a mask of enabled message
457classes (represented by ``NETIF_MSG_*`` constants); therefore netlink
458interface follows its actual use in practice.
459
460``DEBUG_GET`` allows dump requests (kernel returns reply messages for all
461devices supporting the request).
462
463
464DEBUG_SET
465=========
466
467Set or update debugging settings of a device. At the moment, only message mask
468is supported.

477``ETHTOOL_A_DEBUG_MSGMASK`` bit set allows setting or modifying mask of
478enabled debugging message types for the device.

481WOL_GET
482=======
483
484Query device wake-on-lan settings. Unlike most "GET" type requests,
485``ETHTOOL_MSG_WOL_GET`` requires (netns) ``CAP_NET_ADMIN`` privileges as it
486(potentially) provides SecureOn(tm) password which is confidential.
