stable inclusion from stable-5.10.60 commit bae5b521feaa9ce08d7cf0a60c9c955ca76b2cf1 bugzilla: 177018 https://gitee.com/openeuler/kernel/issues/I4EAUG Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bae5b521feaa9ce08d7cf0a60c9c955ca76b2cf1 -------------------------------- [ Upstream commit 50ac7479 ] The userspace utility "driverctl" can be used to change/override the system's default driver choices. This is useful in some situations (buggy driver, old driver missing a device ID, trying a workaround, etc.) where the user needs to load a different driver. However, this is also prone to user error, where a driver is mapped to a device it's not designed to drive. For example, if the ice driver is mapped to driver iavf devices, the ice driver crashes. Add a check to return an error if the ice driver is being used to probe a virtual function.
