[PATCH v3 2/6] s390/vfio-ap: loop over the shadow APCB when filtering guest's AP configuration

by Tony Krowiak

While filtering the mdev matrix, it doesn't make sense - and will have unexpected results - to filter an APID from the matrix if the APID or one of the associated APQIs is not in the host's AP configuration. There are two reasons for this: 1. An adapter or domain that is not in the host's AP configuration can be assigned to the matrix; this is known as over-provisioning. Queue devices, however, are only created for adapters and domains in the host's AP configuration, so there will be no queues associated with an over-provisioned adapter or domain to filter. 2. The adapter or domain may have been externally removed from the host's configuration via an SE or HMC attached to a DPM enabled LPAR. In this case, the vfio_ap device driver would have been notified by the AP bus via the on_config_changed callback and the adapter or domain would have already been filtered. Since the matrix_mdev->shadow_apcb.apm and matrix_mdev->shadow_apcb.aqm are copied from the mdev matrix sans the APIDs and APQIs not in the host's AP configuration, let's loop over those bitmaps instead of those assigned to the matrix.

[PATCH v3 1/6] s390/vfio-ap: always filter entire AP matrix

by Tony Krowiak

The vfio_ap_mdev_filter_matrix function is called whenever a new adapter or domain is assigned to the mdev. The purpose of the function is to update the guest's AP configuration by filtering the matrix of adapters and domains assigned to the mdev. When an adapter or domain is assigned, only the APQNs associated with the APID of the new adapter or APQI of the new domain are inspected. If an APQN does not reference a queue device bound to the vfio_ap device driver, then it's APID will be filtered from the mdev's matrix when updating the guest's AP configuration. Inspecting only the APID of the new adapter or APQI of the new domain will result in passing AP queues through to a guest that are not bound to the vfio_ap device driver under certain circumstances. Consider the following: guest's AP configuration (all also assigned to the mdev's matrix): 14.0004 14.0005 14.0006 16.0004 16.0005 16.0006 unassign domain 4 unbind queue 16.0005 assign domain 4 When domain 4 is re-assigned, since only domain 4 will be inspected, the APQNs that will be examined will be: 14.0004 16.0004 Since both of those APQNs reference queue devices that are bound to the vfio_ap device driver, nothing will get filtered from the mdev's matrix when updating the guest's AP configuration. Consequently, queue 16.0005 will get passed through despite not being bound to the driver. This violates the linux device model requirement that a guest shall only be given access to devices bound to the device driver facilitating their pass-through. To resolve this problem, every adapter and domain assigned to the mdev will be inspected when filtering the mdev's matrix.

[PATCH v2 6/6] s390/vfio-ap: do not reset queue removed from host config

by Tony Krowiak

When a queue is unbound from the vfio_ap device driver, it is reset to ensure its crypto data is not leaked when it is bound to another device driver. If the queue is unbound due to the fact that the adapter or domain was removed from the host's AP configuration, then attempting to reset it will fail with response code 01 (APID not valid) getting returned from the reset command. Let's ensure that the queue is assigned to the host's configuration before resetting it.

[PATCH] net: tls, update curr on splice as well

by John Fastabend

commit c5a595000e2677e865a39f249c056bc05d6e55fd upstream. Backport of upstream fix for tls on 5.x kernels. The curr pointer must also be updated on the splice similar to how we do this for other copy types.
