devlink: add split ops generated according to spec Improve the existing devlink spec in order to serve as a source for generation of valid devlink split ops for the existing commands. Add the generated sources. Node that the policies are narrowed down only to the attributes that are actually parsed. The dont-validate-strict parsing policy makes sure that other possibly passed garbage attributes from userspace are ignored during validation.

devlink: define enum for attr types of dynamic attributes Devlink param and health reporter fmsg use attributes with dynamic type which is determined according to a different type. Currently used values are NLA_*. The problem is, they are not part of UAPI. They may change which would cause a break. To make this future safe, introduce a enum that shadows NLA_* values in it and is part of UAPI. Also, this allows to possibly carry types that are unrelated to NLA_* values.

devlink: Fix excessive stack usage in rate TC bandwidth parsing The devlink_nl_rate_tc_bw_parse function uses a large stack array for devlink attributes, which triggers a warning about excessive stack usage: net/devlink/rate.c: In function 'devlink_nl_rate_tc_bw_parse': net/devlink/rate.c:382:1: error: the frame size of 1648 bytes is larger than 1536 bytes [-Werror=frame-larger-than=] Introduce a separate attribute set specifically for rate TC bandwidth parsing that only contains the two attributes actually used: index and bandwidth. This reduces the stack array from DEVLINK_ATTR_MAX entries to just 2 entries, solving the stack usage issue. Update devlink selftest to use the new 'index' and 'bw' attribute names consistent with the YAML spec. Example usage with ynl with the new spec: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-set --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1, "rate-tc-bws": [ {"index": 0, "bw": 50}, {"index": 1, "bw": 50}, {"index": 2, "bw": 0}, {"index": 3, "bw": 0}, {"index": 4, "bw": 0}, {"index": 5, "bw": 0}, {"index": 6, "bw": 0}, {"index": 7, "bw": 0} ] }' ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-get --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1 }' output for rate-get: {'bus-name': 'pci', 'dev-name': '0000:08:00.0', 'port-index': 1, 'rate-tc-bws': [{'bw': 50, 'index': 0}, {'bw': 50, 'index': 1}, {'bw': 0, 'index': 2}, {'bw': 0, 'index': 3}, {'bw': 0, 'index': 4}, {'bw': 0, 'index': 5}, {'bw': 0, 'index': 6}, {'bw': 0, 'index': 7}], 'rate-tx-max': 0, 'rate-tx-priority': 0, 'rate-tx-share': 0, 'rate-tx-weight': 0, 'rate-type': 'leaf'} Fixes: 566e8f108fc7 ("devlink: Extend devlink rate API with traffic classes bandwidth management") Reported-by: Arnd Bergmann <arnd@arndb.de> Closes: https://lore.kernel.org/netdev/20250708160652.1810573-1-arnd@kernel.org/ Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202507171943.W7DJcs6Y-lkp@intel.com/ Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Tested-by: Carolina Jubran <cjubran@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Link: https://patch.msgid.link/1753175609-330621-1-git-send-email-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares. Example: DEV=pci/0000:08:00.0 $ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \ tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0 $ devlink port function rate set $DEV/vfs_group \ tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0 Example usage with ynl: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-set --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1, "rate-tc-bws": [ {"rate-tc-index": 0, "rate-tc-bw": 50}, {"rate-tc-index": 1, "rate-tc-bw": 50}, {"rate-tc-index": 2, "rate-tc-bw": 0}, {"rate-tc-index": 3, "rate-tc-bw": 0}, {"rate-tc-index": 4, "rate-tc-bw": 0}, {"rate-tc-index": 5, "rate-tc-bw": 0}, {"rate-tc-index": 6, "rate-tc-bw": 0}, {"rate-tc-index": 7, "rate-tc-bw": 0} ] }' ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-get --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1 }' output for rate-get: {'bus-name': 'pci', 'dev-name': '0000:08:00.0', 'port-index': 1, 'rate-tc-bws': [{'rate-tc-bw': 50, 'rate-tc-index': 0}, {'rate-tc-bw': 50, 'rate-tc-index': 1}, {'rate-tc-bw': 0, 'rate-tc-index': 2}, {'rate-tc-bw': 0, 'rate-tc-index': 3}, {'rate-tc-bw': 0, 'rate-tc-index': 4}, {'rate-tc-bw': 0, 'rate-tc-index': 5}, {'rate-tc-bw': 0, 'rate-tc-index': 6}, {'rate-tc-bw': 0, 'rate-tc-index': 7}], 'rate-tx-max': 0, 'rate-tx-priority': 0, 'rate-tx-share': 0, 'rate-tx-weight': 0, 'rate-type': 'leaf'} Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Cosmin Ratiu <cratiu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Mark Bloch <mbloch@nvidia.com> Link: https://patch.msgid.link/20250629142138.361537-3-mbloch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: Introduce switchdev_inactive eswitch mode Adds DEVLINK_ESWITCH_MODE_SWITCHDEV_INACTIVE attribute to UAPI and documentation. Before having traffic flow through an eswitch, a user may want to have the ability to block traffic towards the FDB until FDB is fully programmed and the user is ready to send traffic to it. For example: when two eswitches are present for vports in a multi-PF setup, one eswitch may take over the traffic from the other when the user chooses. Before this take over, a user may want to first program the inactive eswitch and then once ready redirect traffic to this new eswitch. switchdev modes transition semantics: legacy->switchdev_inactive: Create switchdev mode normally, traffic not allowed to flow yet. switchdev_inactive->switchdev: Enable traffic to flow. switchdev->switchdev_inactive: Block traffic on the FDB, FDB and representros state and content is preserved. When eswitch is configured to this mode, traffic is ignored/dropped on this eswitch FDB, while current configuration is kept, e.g FDB rules and netdev representros are kept available, FDB programming is allowed. Example: # start inactive switchdev devlink dev eswitch set pci/0000:08:00.1 mode switchdev_inactive # setup TC rules, representors etc .. # activate devlink dev eswitch set pci/0000:08:00.1 mode switchdev Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Link: https://patch.msgid.link/20251108070404.1551708-2-saeed@kernel.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>

devlink: support default values for param-get and param-set Support querying and resetting to default param values. Introduce two new devlink netlink attrs: DEVLINK_ATTR_PARAM_VALUE_DEFAULT and DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an optional parameter value inside of the param_value nested attribute. The latter is used in param-set requests from userspace to indicate that the driver should reset the param to its default value. To implement this, two new functions are added to the devlink driver api: devlink_param::get_default() and devlink_param::reset_default(). These callbacks allow drivers to implement default param actions for runtime and permanent cmodes. For driverinit params, the core latches the last value set by a driver via devl_param_driverinit_value_set(), and uses that as the default value for a param. Because default parameter values are optional, it would be impossible to discern whether or not a param of type bool has default value of false or not provided if the default value is encoded using a netlink flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an associated default value, the default value is encoded using a u8 type.

Currently used values are NLA_*. The problem is, they are not part of UAPI. They may change which would cause a break. To make this future safe, introduce a enum that shadows NLA_* values in it and is part of UAPI. Also, this allows to possibly carry types that are unrelated to NLA_* values.

devlink: Make health reporter burst period configurable Enable configuration of the burst period — a time window starting from the first error recovery, during which the reporter allows recovery attempts for each reported error. This feature is helpful when a single underlying issue causes multiple errors, as it delays the start of the grace period to allow sufficient time for recovering all related errors. For example, if multiple TX queues time out simultaneously, a sufficient burst period could allow all affected TX queues to be recovered within that window. Without this period, only the first TX queue that reports a timeout will undergo recovery, while the remaining TX queues will be blocked once the grace period begins.

devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares. Example: DEV=pci/0000:08:00.0 $ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \ tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0 $ devlink port function rate set $DEV/vfs_group \ tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0 Example usage with ynl: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-set --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1, "rate-tc-bws": [ {"rate-tc-index": 0, "rate-tc-bw": 50}, {"rate-tc-index": 1, "rate-tc-bw": 50}, {"rate-tc-index": 2, "rate-tc-bw": 0}, {"rate-tc-index": 3, "rate-tc-bw": 0}, {"rate-tc-index": 4, "rate-tc-bw": 0}, {"rate-tc-index": 5, "rate-tc-bw": 0}, {"rate-tc-index": 6, "rate-tc-bw": 0}, {"rate-tc-index": 7, "rate-tc-bw": 0} ] }' ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-get --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1 }' output for rate-get: {'bus-name': 'pci', 'dev-name': '0000:08:00.0', 'port-index': 1, 'rate-tc-bws': [{'rate-tc-bw': 50, 'rate-tc-index': 0}, {'rate-tc-bw': 50, 'rate-tc-index': 1}, {'rate-tc-bw': 0, 'rate-tc-index': 2}, {'rate-tc-bw': 0, 'rate-tc-index': 3}, {'rate-tc-bw': 0, 'rate-tc-index': 4}, {'rate-tc-bw': 0, 'rate-tc-index': 5}, {'rate-tc-bw': 0, 'rate-tc-index': 6}, {'rate-tc-bw': 0, 'rate-tc-index': 7}], 'rate-tx-max': 0, 'rate-tx-priority': 0, 'rate-tx-share': 0, 'rate-tx-weight': 0, 'rate-type': 'leaf'} Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Cosmin Ratiu <cratiu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Mark Bloch <mbloch@nvidia.com> Link: https://patch.msgid.link/20250629142138.361537-3-mbloch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares. Example: DEV=pci/0000:08:00.0 $ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \ tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0 $ devlink port function rate set $DEV/vfs_group \ tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0 Example usage with ynl: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-set --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1, "rate-tc-bws": [ {"rate-tc-index": 0, "rate-tc-bw": 50}, {"rate-tc-index": 1, "rate-tc-bw": 50}, {"rate-tc-index": 2, "rate-tc-bw": 0}, {"rate-tc-index": 3, "rate-tc-bw": 0}, {"rate-tc-index": 4, "rate-tc-bw": 0}, {"rate-tc-index": 5, "rate-tc-bw": 0}, {"rate-tc-index": 6, "rate-tc-bw": 0}, {"rate-tc-index": 7, "rate-tc-bw": 0} ] }' ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-get --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1 }' output for rate-get: {'bus-name': 'pci', 'dev-name': '0000:08:00.0', 'port-index': 1, 'rate-tc-bws': [{'rate-tc-bw': 50, 'rate-tc-index': 0}, {'rate-tc-bw': 50, 'rate-tc-index': 1}, {'rate-tc-bw': 0, 'rate-tc-index': 2}, {'rate-tc-bw': 0, 'rate-tc-index': 3}, {'rate-tc-bw': 0, 'rate-tc-index': 4}, {'rate-tc-bw': 0, 'rate-tc-index': 5}, {'rate-tc-bw': 0, 'rate-tc-index': 6}, {'rate-tc-bw': 0, 'rate-tc-index': 7}], 'rate-tx-max': 0, 'rate-tx-priority': 0, 'rate-tx-share': 0, 'rate-tx-weight': 0, 'rate-type': 'leaf'} Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Cosmin Ratiu <cratiu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Mark Bloch <mbloch@nvidia.com> Link: https://patch.msgid.link/20250629142138.361537-3-mbloch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: Acquire device lock during reload command Device drivers register with devlink from their probe routines (under the device lock) by acquiring the devlink instance lock and calling devl_register(). Drivers that support a devlink reload usually implement the reload_{down, up}() operations in a similar fashion to their remove and probe routines, respectively. However, while the remove and probe routines are invoked with the device lock held, the reload operations are only invoked with the devlink instance lock held. It is therefore impossible for drivers to acquire the device lock from their reload operations, as this would result in lock inversion. The motivating use case for invoking the reload operations with the device lock held is in mlxsw which needs to trigger a PCI reset as part of the reload. The driver cannot call pci_reset_function() as this function acquires the device lock. Instead, it needs to call __pci_reset_function_locked which expects the device lock to be held. To that end, adjust devlink to always acquire the device lock before the devlink instance lock when performing a reload. Do that when reload is explicitly triggered by user space by specifying the 'DEVLINK_NL_FLAG_NEED_DEV_LOCK' flag in the pre_doit and post_doit operations of the reload command. A previous patch already handled the case where reload is invoked as part of netns dismantle.

devlink: support default values for param-get and param-set Support querying and resetting to default param values. Introduce two new devlink netlink attrs: DEVLINK_ATTR_PARAM_VALUE_DEFAULT and DEVLINK_ATTR_PARAM_RESET_DEFAULT. The former is used to contain an optional parameter value inside of the param_value nested attribute. The latter is used in param-set requests from userspace to indicate that the driver should reset the param to its default value. To implement this, two new functions are added to the devlink driver api: devlink_param::get_default() and devlink_param::reset_default(). These callbacks allow drivers to implement default param actions for runtime and permanent cmodes. For driverinit params, the core latches the last value set by a driver via devl_param_driverinit_value_set(), and uses that as the default value for a param. Because default parameter values are optional, it would be impossible to discern whether or not a param of type bool has default value of false or not provided if the default value is encoded using a netlink flag type. For this reason, when a DEVLINK_PARAM_TYPE_BOOL has an associated default value, the default value is encoded using a u8 type.

devlink: Make health reporter burst period configurable Enable configuration of the burst period — a time window starting from the first error recovery, during which the reporter allows recovery attempts for each reported error. This feature is helpful when a single underlying issue causes multiple errors, as it delays the start of the grace period to allow sufficient time for recovering all related errors. For example, if multiple TX queues time out simultaneously, a sufficient burst period could allow all affected TX queues to be recovered within that window. Without this period, only the first TX queue that reports a timeout will undergo recovery, while the remaining TX queues will be blocked once the grace period begins. Configuration example: $ devlink health set pci/0000:00:09.0 reporter tx burst_period 500 Configuration example with ynl: ./tools/net/ynl/pyynl/cli.py \ --spec Documentation/netlink/specs/devlink.yaml \ --do health-reporter-set --json '{ "bus-name": "auxiliary", "dev-name": "mlx5_core.eth.0", "port-index": 65535, "health-reporter-name": "tx", "health-reporter-burst-period": 500 }' Signed-off-by: Shahar Shitrit <shshitrit@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Reviewed-by: Dragos Tatulea <dtatulea@nvidia.com> Reviewed-by: Carolina Jubran <cjubran@nvidia.com> Signed-off-by: Mark Bloch <mbloch@nvidia.com> Link: https://patch.msgid.link/20250824084354.533182-5-mbloch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: Extend devlink rate API with traffic classes bandwidth management Introduce support for specifying relative bandwidth shares between traffic classes (TC) in the devlink-rate API. This new option allows users to allocate bandwidth across multiple traffic classes in a single command. This feature provides a more granular control over traffic management, especially for scenarios requiring Enhanced Transmission Selection. Users can now define a relative bandwidth share for each traffic class. For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5 (RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the total bandwidth. The actual percentage each class receives depends on the ratio of its share value to the sum of all shares. Example: DEV=pci/0000:08:00.0 $ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \ tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0 $ devlink port function rate set $DEV/vfs_group \ tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0 Example usage with ynl: ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-set --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1, "rate-tc-bws": [ {"rate-tc-index": 0, "rate-tc-bw": 50}, {"rate-tc-index": 1, "rate-tc-bw": 50}, {"rate-tc-index": 2, "rate-tc-bw": 0}, {"rate-tc-index": 3, "rate-tc-bw": 0}, {"rate-tc-index": 4, "rate-tc-bw": 0}, {"rate-tc-index": 5, "rate-tc-bw": 0}, {"rate-tc-index": 6, "rate-tc-bw": 0}, {"rate-tc-index": 7, "rate-tc-bw": 0} ] }' ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \ --do rate-get --json '{ "bus-name": "pci", "dev-name": "0000:08:00.0", "port-index": 1 }' output for rate-get: {'bus-name': 'pci', 'dev-name': '0000:08:00.0', 'port-index': 1, 'rate-tc-bws': [{'rate-tc-bw': 50, 'rate-tc-index': 0}, {'rate-tc-bw': 50, 'rate-tc-index': 1}, {'rate-tc-bw': 0, 'rate-tc-index': 2}, {'rate-tc-bw': 0, 'rate-tc-index': 3}, {'rate-tc-bw': 0, 'rate-tc-index': 4}, {'rate-tc-bw': 0, 'rate-tc-index': 5}, {'rate-tc-bw': 0, 'rate-tc-index': 6}, {'rate-tc-bw': 0, 'rate-tc-index': 7}], 'rate-tx-max': 0, 'rate-tx-priority': 0, 'rate-tx-share': 0, 'rate-tx-weight': 0, 'rate-type': 'leaf'} Signed-off-by: Carolina Jubran <cjubran@nvidia.com> Reviewed-by: Cosmin Ratiu <cratiu@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Mark Bloch <mbloch@nvidia.com> Link: https://patch.msgid.link/20250629142138.361537-3-mbloch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

devlink: add a command to set notification filter and use it for multicasts Currently the user listening on a socket for devlink notifications gets always all messages for all existing instances, even if he is interested only in one of those. That may cause unnecessary overhead on setups with thousands of instances present. User is currently able to narrow down the devlink objects replies to dump commands by specifying select attributes. Allow similar approach for notifications. Introduce a new devlink NOTIFY_FILTER_SET which the user passes the select attributes. Store these per-socket and use them for filtering messages during multicast send. Signed-off-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

devlink: add split ops generated according to spec Improve the existing devlink spec in order to serve as a source for generation of valid devlink split ops for the existing commands. Add the generated sources. Node that the policies are narrowed down only to the attributes that are actually parsed. The dont-validate-strict parsing policy makes sure that other possibly passed garbage attributes from userspace are ignored during validation.
