2020-03-26net: phy: probe PHY drivers synchronouslyHeiner Kallweit1-0/+1
If we have scenarios like mdiobus_register() -> loads PHY driver module(s) -> registers PHY driver(s) -> may schedule async probe phydev = mdiobus_get_phy() <phydev action involving PHY driver> or phydev = phy_device_create() -> loads PHY driver module -> registers PHY driver -> may schedule async probe <phydev action involving PHY driver> then we expect the PHY driver to be bound to the phydev when triggering the action. This may not be the case in case of asynchronous probing. Therefore ensure that PHY drivers are probed synchronously. Default still is sync probing, except async probing is explicitly requested. I saw some comments that the intention is to promote async probing for more parallelism in boot process and want to be prepared for the case that the default is changed to async probing.

2020-03-26Merge branch 'implement-DEVLINK_CMD_REGION_NEW'David S. Miller11-79/+546
Jacob Keller says: ==================== implement DEVLINK_CMD_REGION_NEW This series adds support for the DEVLINK_CMD_REGION_NEW operation, used to enable userspace requesting a snapshot of a region on demand. This can be useful to enable adding regions for a driver for which there is no trigger to create snapshots. By making this a core part of devlink, there is no need for the drivers to use a separate channel such as debugfs. The primary intent for this kind of region is to expose device information that might be useful for diagnostics and information gathering. The first few patches refactor regions to support a new ops structure for extending the available operations that regions can perform. This includes converting the destructor into an op from a function argument. Next, patches refactor the snapshot id allocation to use an xarray which tracks the number of current snapshots using a given id. This is done so that id lifetime can be determined, and ids can be released when no longer in use. Without this change, snapshot ids remain used forever, until the snapshot_id count rolled over UINT_MAX. Finally, code to enable the previously unused DEVLINK_CMD_REGION_NEW is added. This code enforces that the snapshot id is always provided, unlike previous revisions of this series. Finally, a patch is added to enable using this new command via the .snapshot callback in both netdevsim and the ice driver. For the ice driver, a new "nvm-flash" region is added, which will enable read access to the NVM flash contents. The intention for this is to allow diagnostics tools to gather information about the device. By using a snapshot and gathering the NVM contents all at once, the contents can be atomic.

2020-03-26devlink: implement DEVLINK_CMD_REGION_NEWJacob Keller3-0/+113
Implement support for the DEVLINK_CMD_REGION_NEW command for creating snapshots. This new command parallels the existing DEVLINK_CMD_REGION_DEL. In order for DEVLINK_CMD_REGION_NEW to work for a region, the new ".snapshot" operation must be implemented in the region's ops structure. The desired snapshot id must be provided. This helps avoid confusion on the purpose of DEVLINK_CMD_REGION_NEW, and keeps the API simpler. The requested id will be inserted into the xarray tracking the number of snapshots using each id. If this id is already used by another snapshot on any region, an error will be returned.

2020-03-26devlink: track snapshot id usage count using an xarrayJacob Keller4-8/+135
Each snapshot created for a devlink region must have an id. These ids are supposed to be unique per "event" that caused the snapshot to be created. Drivers call devlink_region_snapshot_id_get to obtain a new id to use for a new event trigger. The id values are tracked per devlink, so that the same id number can be used if a triggering event creates multiple snapshots on different regions. There is no mechanism for snapshot ids to ever be reused. Introduce an xarray to store the count of how many snapshots are using a given id, replacing the snapshot_id field previously used for picking the next id. The devlink_region_snapshot_id_get() function will use xa_alloc to insert an initial value of 1 value at an available slot between 0 and U32_MAX. The new __devlink_snapshot_id_increment() and __devlink_snapshot_id_decrement() functions will be used to track how many snapshots currently use an id. Drivers must now call devlink_snapshot_id_put() in order to release their reference of the snapshot id after adding region snapshots. By tracking the total number of snapshots using a given id, it is possible for the decrement() function to erase the id from the xarray when it is not in use. With this method, a snapshot id can become reused again once all snapshots that referred to it have been deleted via DEVLINK_CMD_REGION_DEL, and the driver has finished adding snapshots. This work also paves the way to introduce a mechanism for userspace to request a snapshot.

2020-03-26devlink: report error once U32_MAX snapshot ids have been usedJacob Keller4-13/+33
The devlink_snapshot_id_get() function returns a snapshot id. The snapshot id is a u32, so there is no way to indicate an error code. A future change is going to possibly add additional cases where this function could fail. Refactor the function to return the snapshot id in an argument, so that it can return zero or an error value. This ensures that snapshot ids cannot be confused with error values, and aids in the future refactor of snapshot id allocation management. Because there is no current way to release previously used snapshot ids, add a simple check ensuring that an error is reported in case the snapshot_id would over flow.

2020-03-26devlink: extract snapshot id allocation to helper functionJacob Keller1-1/+14
A future change is going to implement a new devlink command to request a snapshot on demand. As part of this, the logic for handling the snapshot ids will be refactored. To simplify the snapshot id allocation function, move it to a separate function prefixed by `__`. This helper function will assume the lock is held. While no other callers will exist, it simplifies refactoring the logic because there is no need to complicate the function with gotos to handle unlocking on failure.

This prepares the regions to enable support of additional operations in the future such as requesting snapshots, or accessing the region directly without a snapshot. In order to re-use the constant strings in the mlx4 driver their declaration must be changed to 'const char * const' to ensure the compiler realizes that both the data and the pointer cannot change.

list_for_each_entry_from_reverse() iterates backwards over the list from the current position, but in the error path we should start from the previous position. Fix this by using list_for_each_entry_continue_reverse() instead.

Ido Schimmel says: ==================== mlxsw: Offload TC action pedit munge dsfield Petr says: The Spectrum switches allow packet prioritization based on DSCP on ingress, and update of DSCP on egress. This is configured through the DCB APP rules. For some use cases, assigning a custom DSCP value based on an ACL match is a better tool. To that end, offload FLOW_ACTION_MANGLE to permit changing of dsfield as a whole, or DSCP and ECN values in isolation. After fixing a commentary nit in patch #1, and mlxsw naming in patch #2, patches #3 and #4 add the offload to mlxsw. Patch #5 adds a forwarding selftest for pedit dsfield, applicable to SW as well as HW datapaths. Patch #6 adds a mlxsw-specific test to verify DSCP rewrite due to DCB APP rules is not performed on pedited packets. The tests only cover IPv4 dsfield setting. We have tests for IPv6 as well, but would like to postpone their contribution until the corresponding iproute patches have been accepted. ==================== Signed-off-by: David S.

When DSCP is updated through an offloaded pedit action, DSCP rewrite on egress should be disabled. Add a test that check that it is so. Signed-off-by: Petr Machata <[email protected]> Signed-off-by: Ido Schimmel <[email protected]> Signed-off-by: David S. Miller <[email protected]>

Offload action pedit ex munge when used with a flower classifier. Only allow setting of DSCP, ECN, or the whole DSField in IPv4 and IPv6 packets.

2020-03-26mlxsw: core: Rename mlxsw_afa_qos_cmd to mlxsw_afa_qos_switch_prio_cmdPetr Machata1-7/+7
The original idea was to reuse this set of actions for ECN rewrite as well, but on second look, it's not such a great idea. These two items should each have its own command. Rename the existing enum to make it obvious that it belongs to switch_prio_cmd.
