Revision 61f36166c245e563c7a2b624f4c78c5ce0f680d6 authored by Nicholas Bellinger on 16 October 2016, 07:27:42 UTC, committed by Nicholas Bellinger on 20 October 2016, 04:22:34 UTC
This reverts commit c1ccbfe0311e2380a6d2dcb0714b36904f5d586f. Reverting this patch, as it incorrectly assumes the additional length for INQUIRY in target_complete_cmd_with_length() is SCSI allocation length, which breaks existing user-space code when SCSI allocation length is smaller than additional length. root@scsi-mq:~# sg_inq --len=4 -vvvv /dev/sdb found bsg_major=253 open /dev/sdb with flags=0x800 inquiry cdb: 12 00 00 00 04 00 duration=0 ms inquiry: pass-through requested 4 bytes (data-in) but got -28 bytes inquiry: pass-through can't get negative bytes, say it got none inquiry: got too few bytes (0) INQUIRY resid (32) should never exceed requested len=4 inquiry: failed requesting 4 byte response: Malformed response to SCSI command [resid=32] AFAICT the original change was not to address a specific host issue, so go ahead and revert to original logic for now.
