- Summary
- net/mlx5: Register devlink first under devlink lock
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Register devlink first under devlink lock
In case device is having a non fatal FW error during probe, the driver will report the error to user via devlink. This will trigger a WARNON, since mlx5 is calling devlinkregister() last. In order to avoid the WARNON[1], change mlx5 to invoke devlregister() first under devlink lock.
