libopeniscsiusr-dev 2.1.3-1ubuntu5 (amd64 binary) in ubuntu hirsute

 The Open-iSCSI project is a high-performance, transport independent,
 multi-platform implementation of RFC3720 iSCSI.
 .
 Open-iSCSI is partitioned into user and kernel parts.
 .
 The kernel portion of Open-iSCSI is a from-scratch code
 licensed under GPL. The kernel part implements iSCSI data path
 (that is, iSCSI Read and iSCSI Write), and consists of three
 loadable modules: scsi_transport_iscsi.ko, libiscsi.ko and iscsi_tcp.ko.
 .
 User space contains the entire control plane: configuration
 manager, iSCSI Discovery, Login and Logout processing,
 connection-level error processing, Nop-In and Nop-Out handling,
 and (in the future:) Text processing, iSNS, SLP, Radius, etc.
 .
 The user space Open-iSCSI consists of a daemon process called
 iscsid, and a management utility iscsiadm.
 .
 This package contains the iSCSI userspace library headers.
