5.294. scsi-target-utils

Previously, scsi-target-utils did not accurately report certain parameters, such as the native block size of the "direct-store" backing store, lowest aligned logical block address, and optimal transfer length. This could decrease performance of iSCSI devices. This update adds support for the "B0 VPD" and "READ CAPACITY(16)" SCSI commands to match the characteristics of the iSCSI device to its underlying backing store, which improves performance of the iSCSI device.

With this update, scsi-target-utils now supports authentication for target discovery. It may be configured using the "incomingdiscoveryuser" and "outgoingdiscoveryuser" directives in the "/etc/tgt/targets.conf" file. Configuration details can be seen in the targets.conf(5) manual page.
