2022-12-14thermal/drivers/k3_j72xx_bandgap: Map fuse_base only for erratum workaroundBryan Brattlof
Some of TI's J721E SoCs require a software trimming procedure for the temperature monitors to function properly. To determine if a particular J721E is not affected by this erratum, both bits in the WKUP_SPARE_FUSE0 region must be set. Other SoCs, not affected by this erratum, will not need this region.

2022-12-14thermal/drivers/qcom/tsens: Rework debugfs file structureChristian Marangi
The current tsens debugfs structure is composed by: - a tsens dir in debugfs with a version file - a directory for each tsens istance with sensors file to dump all the sensors value. This works on the assumption that we have the same version for each istance but this assumption seems fragile and with more than one tsens istance results in the version file not tracking each of them. A better approach is to just create a subdirectory for each tsens istance and put there version and sensors debugfs file. Using this new implementation results in less code since debugfs entry are created only on successful tsens probe.

When a MAC address is not assigned to the VF, that portion of the message sent to the VF is not set. The memory, however, is allocated from the stack meaning that information may be leaked to the VM. Initialize the message buffer to 0 so that no information is passed to the VM in this case.

2022-12-14scsi: storvsc: Fix swiotlb bounce buffer leak in confidential VMMichael Kelley
storvsc_queuecommand() maps the scatter/gather list using scsi_dma_map(), which in a confidential VM allocates swiotlb bounce buffers. If the I/O submission fails in storvsc_do_io(), the I/O is typically retried by higher level code, but the bounce buffer memory is never freed. The mostly like cause of I/O submission failure is a full VMBus channel ring buffer, which is not uncommon under high I/O loads. Eventually enough bounce buffer memory leaks that the confidential VM can't do any I/O. The same problem can arise in a non-confidential VM with kernel boot parameter swiotlb=force. Fix this by doing scsi_dma_unmap() in the case of an I/O submission error, which frees the bounce buffer memory.

2022-12-14scsi: iscsi: Fix multiple iSCSI session unbind events sent to userspaceWenchao Hao
It was observed that the kernel would potentially send ISCSI_KEVENT_UNBIND_SESSION multiple times. Introduce 'target_state' in iscsi_cls_session() to make sure session will send only one unbind session event. This introduces a regression wrt. the issue fixed in commit 13e60d3ba287 ("scsi: iscsi: Report unbind session event when the target has been removed"). If iscsid dies for any reason after sending an unbind session to kernel, once iscsid is restarted, the kernel's ISCSI_KEVENT_UNBIND_SESSION event is lost and userspace is then unable to logout. However, the session is actually in invalid state (its target_id is INVALID) so iscsid should not sync this session during restart. Consequently we need to check the session's target state during iscsid restart. If session is in unbound state, do not sync this session and perform session teardown. This is OK because once a session is unbound, we can not recover it any more (mainly because its target id is INVALID).
