From: Roland Dreier Date: Tue, 10 Jan 2012 01:54:00 +0000 (-0800) Subject: target: Correct sense key for INVALID FIELD IN {PARAMETER LIST,CDB} X-Git-Tag: v3.2.6~18 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f4d055fceeb62aca2303fe076d17005a662690a3;p=karo-tx-linux.git target: Correct sense key for INVALID FIELD IN {PARAMETER LIST,CDB} commit 9fbc8909876a2160044e71d376848973b9bfdc3f upstream. According to SPC-4, the sense key for commands that are failed with INVALID FIELD IN PARAMETER LIST and INVALID FIELD IN CDB should be ILLEGAL REQUEST (5h) rather than ABORTED COMMAND (Bh). Without this patch, a tcm_loop LUN incorrectly gives: # sg_raw -r 1 -v /dev/sda 3 1 0 0 ff 0 Sense Information: Fixed format, current; Sense key: Aborted Command Additional sense: Invalid field in cdb Raw sense data (in hex): 70 00 0b 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 While a real SCSI disk gives: Sense Information: Fixed format, current; Sense key: Illegal Request Additional sense: Invalid field in cdb Raw sense data (in hex): 70 00 05 00 00 00 00 18 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 with the main point being that the real disk gives a sense key of ILLEGAL REQUEST (5h).
