This is a note to let you know that I've just added the patch titled virtio_pci: modify ENOENT to EINVAL to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: virtio_pci-modify-enoent-to-einval.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b97590a31aa3757a945883c5593ece254fc8b055 Author: Angus Chen <angus.chen@xxxxxxxxxxxxxxx> Date: Tue Nov 1 19:16:54 2022 +0800 virtio_pci: modify ENOENT to EINVAL [ Upstream commit b66ead2d0ecac00c3a06a6218af5411cb5fcb5d5 ] Virtio_crypto use max_data_queues+1 to setup vqs, we use vp_modern_get_num_queues to protect the vq range in setup_vq. We could enter index >= vp_modern_get_num_queues(mdev) in setup_vq if common->num_queues is not set well,and it return -ENOENT. It is better to use -EINVAL instead.
