Dmitry Tikhov d7fe639cab hw/nvme: add new command abort case ... NVMe command set specification for end-to-end data protection formatted namespace states: o If the Reference Tag Check bit of the PRCHK field is set to ‘1’ and the namespace is formatted for Type 3 protection, then the controller: ▪ should not compare the protection Information Reference Tag field to the computed reference tag; and ▪ may ignore the ILBRT and EILBRT fields. If a command is aborted as a result of the Reference Tag Check bit of the PRCHK field being set to ‘1’, then that command should be aborted with a status code of Invalid Protection Information, but may be aborted with a status code of Invalid Field in Command. Currently qemu compares reftag in the nvme_dif_prchk function whenever Reference Tag Check bit is set in the command. For type 3 namespaces however, caller of nvme_dif_prchk - nvme_dif_check does not increment reftag for each subsequent logical block. That way commands incorporating more than one logical block for type 3 formatted namespaces with reftag check bit set, always fail with End-to-end Reference Tag Check Error. Comply with spec by handling case of set Reference Tag Check bit in the type 3 formatted namespace.
