Fedora 33: 2021-4a91649cf3 Medium: tcmu-runner Access Control Fix

A daemon that handles the complexity of the LIO kernel target's userspace

passthrough interface (TCMU). It presents a C plugin API for extension modules

that handle SCSI requests in ways not possible or suitable to be handled

by LIO's in-kernel backstores.

Fixes CVE-2020-28374 See tcmu-runner commit

2b16e96e6b63d0419d857f53e4cc67f0adb383fd tcmu-runner can't determine whether

the device(s) referred to in XCOPY Copy Source/Copy Destination (CSCD)

descriptors should be accessible to the initiator via transport settings, ACLs,

etc. Consequently, fail XCOPY requests with CSCD descriptors which refer to any

device other than where the XCOPY request is processed.
