From bb1d1073a10fdc8547e3eb821ee2488260094b39 Mon Sep 17 00:00:00 2001 From: "brking@us.ibm.com" Date: Mon, 23 Jan 2006 15:03:22 -0600 Subject: [SCSI] Prevent scsi_execute_async from guessing cdb length When the scsi_execute_async interface was added it ended up reducing the flexibility of userspace to send arbitrary scsi commands through sg using SG_IO. The SG_IO interface allows userspace to specify the CDB length. This is now ignored in scsi_execute_async and it is guessed using the COMMAND_SIZE macro, which is not always correct, particularly for vendor specific commands. This patch adds a cmd_len parameter to the scsi_execute_async interface to allow the caller to specify the length of the CDB.
