RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
