Description Stefano Garzarella 2022-07-15 13:30:03 UTC

The following patches are available upstream (Linux 5.19-rc6) and we should backport in RHEL 9.1:

bd50c5dc182b vsock/virtio: add support for device suspend/resume
a10320988626 vsock/virtio: factor our the code to initialize and delete VQs
dbde6d0c7a5a hv_sock: Add validation for untrusted Hyper-V values
88704454ef8b vsock/virtio: enable VQs early on probe
c1011c0b3a9c vsock/virtio: read the negotiated features before using VQs
4b5f1ad5566a vsock/virtio: initialize vdev->priv before using VQs
e89600ebeeb1 af_vsock: SOCK_SEQPACKET broken buffer test
efb3719f4ab0 af_vsock: SOCK_SEQPACKET receive timeout test
8e6ed963763f vsock: each transport cycles only on its own sockets
a58da53ffd70 vhost/vsock: don't check owner in vhost_vsock_stop() while releasing
b9208492fcae vsock: remove vsock from connected table when connect is interrupted by a signal

Most of them are fixes, the only new feature is the support for device suspend/resume.
