devlink: rename netlink callback to be aligned with the generated ones

2023-10-23T23:12:47Z

All remaining doit and dumpit netlink callback functions are going to be used by generated split ops. They expect certain name format. Rename the callback to be aligned with generated names.

devlink: introduce possibility to expose info about nested devlinks

2023-09-17T13:01:47Z

In mlx5, there is a devlink instance created for PCI device. Also, one separate devlink instance is created for auxiliary device that represents the netdev of uplink port. This relation is currently invisible to the devlink user. Benefit from the rel infrastructure and allow for nested devlink instance to set the relationship for the nested-in devlink instance. Note that there may be many nested instances, therefore use xarray to hold the list of rel_indexes for individual nested instances. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: introduce object and nested devlink relationship infra

2023-09-17T13:01:47Z

It is a bit tricky to maintain relationship between devlink objects and nested devlink instances due to following aspects: 1) Locking. It is necessary to lock the devlink instance that contains the object first, only after that to lock the nested instance. 2) Lifetimes. Objects (e.g devlink port) may be removed before the nested devlink instance. 3) Notifications. If nested instance changes (e.g. gets registered/unregistered) the nested-in object needs to send appropriate notifications. Resolve this by introducing an xarray that holds 1:1 relationships between devlink object and related nested devlink instance. Use that xarray index to get the object/nested devlink instance on the other side. Provide necessary helpers: devlink_rel_nested_in_add/clear() to add and clear the relationship. devlink_rel_nested_in_notify() to call the nested-in object to send notifications during nested instance register/unregister/netns change. devlink_rel_devlink_handle_put() to be used by nested-in object fill function to fill the nested handle.

devlink: pass flags as an arg of dump_one() callback

2023-08-14T18:47:25Z

In order to easily set NLM_F_DUMP_FILTERED for partial dumps, pass the flags as an arg of dump_one() callback. Currently, it is always NLM_F_MULTI.

devlink: introduce dumpit callbacks for split ops

2023-08-14T18:47:24Z

Introduce dumpit callbacks for generated split ops. Have them as a thin wrapper around iteration function and allow to pass dump_one() function pointer directly without need to store in devlink_cmd structs. Note that the function prototypes are temporary until the generated ones will replace them in a follow-up patch.

devlink: rename doit callbacks for per-instance dump commands

2023-08-14T18:47:24Z

Rename netlink doit callback functions for the commands that do implement per-instance dump to match the generated names that are going to be introduce in the follow-up patch.
