1============================= 2Netlink interface for ethtool 3============================= 4 5 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 ``ETHTOOL_MSG_FEATURES_GET`` get device features 193 ``ETHTOOL_MSG_FEATURES_SET`` set device features 194 ``ETHTOOL_MSG_PRIVFLAGS_GET`` get private flags 195 ``ETHTOOL_MSG_PRIVFLAGS_SET`` set private flags 196 ``ETHTOOL_MSG_RINGS_GET`` get ring sizes 197 ``ETHTOOL_MSG_RINGS_SET`` set ring sizes 198 ``ETHTOOL_MSG_CHANNELS_GET`` get channel counts 199 ``ETHTOOL_MSG_CHANNELS_SET`` set channel counts 200 ``ETHTOOL_MSG_COALESCE_GET`` get coalescing parameters 201 ``ETHTOOL_MSG_COALESCE_SET`` set coalescing parameters 202 ``ETHTOOL_MSG_PAUSE_GET`` get pause parameters 203 ``ETHTOOL_MSG_PAUSE_SET`` set pause parameters 204 ``ETHTOOL_MSG_EEE_GET`` get EEE settings 205 ``ETHTOOL_MSG_EEE_SET`` set EEE settings 206 ``ETHTOOL_MSG_TSINFO_GET`` get timestamping info 207 ===================================== ================================ 208 209Kernel to userspace: 210 211 ===================================== ================================= 212 ``ETHTOOL_MSG_STRSET_GET_REPLY`` string set contents 213 ``ETHTOOL_MSG_LINKINFO_GET_REPLY`` link settings 214 ``ETHTOOL_MSG_LINKINFO_NTF`` link settings notification 215 ``ETHTOOL_MSG_LINKMODES_GET_REPLY`` link modes info 216 ``ETHTOOL_MSG_LINKMODES_NTF`` link modes notification 217 ``ETHTOOL_MSG_LINKSTATE_GET_REPLY`` link state info 218 ``ETHTOOL_MSG_DEBUG_GET_REPLY`` debugging settings 219 ``ETHTOOL_MSG_DEBUG_NTF`` debugging settings notification 220 ``ETHTOOL_MSG_WOL_GET_REPLY`` wake-on-lan settings 221 ``ETHTOOL_MSG_WOL_NTF`` wake-on-lan settings notification 222 ``ETHTOOL_MSG_FEATURES_GET_REPLY`` device features 223 ``ETHTOOL_MSG_FEATURES_SET_REPLY`` optional reply to FEATURES_SET 224 ``ETHTOOL_MSG_FEATURES_NTF`` netdev features notification 225 ``ETHTOOL_MSG_PRIVFLAGS_GET_REPLY`` private flags 226 ``ETHTOOL_MSG_PRIVFLAGS_NTF`` private flags 227 ``ETHTOOL_MSG_RINGS_GET_REPLY`` ring sizes 228 ``ETHTOOL_MSG_RINGS_NTF`` ring sizes 229 ``ETHTOOL_MSG_CHANNELS_GET_REPLY`` channel counts 230 ``ETHTOOL_MSG_CHANNELS_NTF`` channel counts 231 ``ETHTOOL_MSG_COALESCE_GET_REPLY`` coalescing parameters 232 ``ETHTOOL_MSG_COALESCE_NTF`` coalescing parameters 233 ``ETHTOOL_MSG_PAUSE_GET_REPLY`` pause parameters 234 ``ETHTOOL_MSG_PAUSE_NTF`` pause parameters 235 ``ETHTOOL_MSG_EEE_GET_REPLY`` EEE settings 236 ``ETHTOOL_MSG_EEE_NTF`` EEE settings 237 ``ETHTOOL_MSG_TSINFO_GET_REPLY`` timestamping info 238 ===================================== ================================= 239 240``GET`` requests are sent by userspace applications to retrieve device 241information. They usually do not contain any message specific attributes. 242Kernel replies with corresponding "GET_REPLY" message. For most types, ``GET`` 243request with ``NLM_F_DUMP`` and no device identification can be used to query 244the information for all devices supporting the request. 245 246If the data can be also modified, corresponding ``SET`` message with the same 247layout as corresponding ``GET_REPLY`` is used to request changes. Only 248attributes where a change is requested are included in such request (also, not 249all attributes may be changed). Replies to most ``SET`` request consist only 250of error code and extack; if kernel provides additional data, it is sent in 251the form of corresponding ``SET_REPLY`` message which can be suppressed by 252setting ``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header. 253 254Data modification also triggers sending a ``NTF`` message with a notification. 255These usually bear only a subset of attributes which was affected by the 256change. The same notification is issued if the data is modified using other 257means (mostly ioctl ethtool interface). Unlike notifications from ethtool 258netlink code which are only sent if something actually changed, notifications 259triggered by ioctl interface may be sent even if the request did not actually 260change any data. 261 262``ACT`` messages request kernel (driver) to perform a specific action. If some 263information is reported by kernel (which can be suppressed by setting 264``ETHTOOL_FLAG_OMIT_REPLY`` flag in request header), the reply takes form of 265an ``ACT_REPLY`` message. Performing an action also triggers a notification 266(``NTF`` message). 267 268Later sections describe the format and semantics of these messages. 269 270 271STRSET_GET 272========== 273 274Requests contents of a string set as provided by ioctl commands 275``ETHTOOL_GSSET_INFO`` and ``ETHTOOL_GSTRINGS.`` String sets are not user 276writeable so that the corresponding ``STRSET_SET`` message is only used in 277kernel replies. There are two types of string sets: global (independent of 278a device, e.g. device feature names) and device specific (e.g. device private 279flags). 280 281Request contents: 282 283 +---------------------------------------+--------+------------------------+ 284 | ``ETHTOOL_A_STRSET_HEADER`` | nested | request header | 285 +---------------------------------------+--------+------------------------+ 286 | ``ETHTOOL_A_STRSET_STRINGSETS`` | nested | string set to request | 287 +-+-------------------------------------+--------+------------------------+ 288 | | ``ETHTOOL_A_STRINGSETS_STRINGSET+`` | nested | one string set | 289 +-+-+-----------------------------------+--------+------------------------+ 290 | | | ``ETHTOOL_A_STRINGSET_ID`` | u32 | set id | 291 +-+-+-----------------------------------+--------+------------------------+ 292 293Kernel response contents: 294 295 +---------------------------------------+--------+-----------------------+ 296 | ``ETHTOOL_A_STRSET_HEADER`` | nested | reply header | 297 +---------------------------------------+--------+-----------------------+ 298 | ``ETHTOOL_A_STRSET_STRINGSETS`` | nested | array of string sets | 299 +-+-------------------------------------+--------+-----------------------+ 300 | | ``ETHTOOL_A_STRINGSETS_STRINGSET+`` | nested | one string set | 301 +-+-+-----------------------------------+--------+-----------------------+ 302 | | | ``ETHTOOL_A_STRINGSET_ID`` | u32 | set id | 303 +-+-+-----------------------------------+--------+-----------------------+ 304 | | | ``ETHTOOL_A_STRINGSET_COUNT`` | u32 | number of strings | 305 +-+-+-----------------------------------+--------+-----------------------+ 306 | | | ``ETHTOOL_A_STRINGSET_STRINGS`` | nested | array of strings | 307 +-+-+-+---------------------------------+--------+-----------------------+ 308 | | | | ``ETHTOOL_A_STRINGS_STRING+`` | nested | one string | 309 +-+-+-+-+-------------------------------+--------+-----------------------+ 310 | | | | | ``ETHTOOL_A_STRING_INDEX`` | u32 | string index | 311 +-+-+-+-+-------------------------------+--------+-----------------------+ 312 | | | | | ``ETHTOOL_A_STRING_VALUE`` | string | string value | 313 +-+-+-+-+-------------------------------+--------+-----------------------+ 314 | ``ETHTOOL_A_STRSET_COUNTS_ONLY`` | flag | return only counts | 315 +---------------------------------------+--------+-----------------------+ 316 317Device identification in request header is optional. Depending on its presence 318a and ``NLM_F_DUMP`` flag, there are three type of ``STRSET_GET`` requests: 319 320 - no ``NLM_F_DUMP,`` no device: get "global" stringsets 321 - no ``NLM_F_DUMP``, with device: get string sets related to the device 322 - ``NLM_F_DUMP``, no device: get device related string sets for all devices 323 324If there is no ``ETHTOOL_A_STRSET_STRINGSETS`` array, all string sets of 325requested type are returned, otherwise only those specified in the request. 326Flag ``ETHTOOL_A_STRSET_COUNTS_ONLY`` tells kernel to only return string 327counts of the sets, not the actual strings. 328 329 330LINKINFO_GET 331============ 332 333Requests link settings as provided by ``ETHTOOL_GLINKSETTINGS`` except for 334link modes and autonegotiation related information.

This 434autoselection is done on ethtool side with ioctl interface, netlink interface 435is supposed to allow requesting changes without knowing what exactly kernel 436supports. 437 438 439LINKSTATE_GET 440============= 441 442Requests link state information.
