From ead0ffc95a89b6b2c276702ee7b5a2b9bb445dfe Mon Sep 17 00:00:00 2001 From: Anastasia Kovaleva Date: Thu, 3 Dec 2020 11:20:35 +0300 Subject: scsi: target: core: Change ASCQ for residual write According to FCP-4 (9.4.2): If the command requested that data beyond the length specified by the FCP_DL field be transferred, then the device server shall set the FCP_RESID_OVER bit (see 9.5.8) to one in the FCP_RSP IU and: a) process the command normally except that data beyond the FCP_DL count shall not be requested or transferred; b) transfer no data and return CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and the additional sense code set to INVALID FIELD IN COMMAND INFORMATION UNIT; or c) may transfer data and return CHECK CONDITION status with the sense key set to ABORTED COMMAND and the additional sense code set to INVALID FIELD IN COMMAND INFORMATION UNIT. TCM follows b) and transfers no data for residual writes but returns INVALID FIELD IN CDB instead of INVALID FIELD IN COMMAND INFORMATION UNIT. Change the ASCQ to INVALID FIELD IN COMMAND INFORMATION UNIT to meet the standard.
