When performing SendTargets discovery, the "iface" NIC binding was ignored. Instead, iscsiadm used the network device determined by the "route" command. SendTargets discovery now occurs through the NIC specified in the "iface" binding information.

If SendTargets discovery required multiple TEXT commands because of a long target list, iscsiadm did not set the Initiator Task Tag in compliance with RFC-3720 as published by the Internet Engineering Task Force. This issue has been fixed, and iscsiadm now sets the Initiator Task Tag correctly.

Attempting to reboot or shut down a system with a running iSCSI daemon caused the system to stop responding because iSCSI sessions remained running. All iSCSI sessions now shut down correctly, so no issues are encountered on shut down or reboot.

Previously, iSCSI did not work on the Broadcom NetXtreme II 1GbE Quad Port Copper Adapter (BCM57712) when connected to a Data Center Bridging-enabled (DCB-enabled) switch over VLAN. This occurred because VLAN tagging was set twice, once by uIP and once by the DCB firmware. This update corrects this issue with VLAN tagging.

The ISCSI_ERR_INVALID_HOST error event was not being handled correctly, leaving iSCSI sessions in memory when the iSCSI driver was attempting to shut down. This resulted in the driver failing to respond during shutdown of sessions that used the Broadcom NetXtreme II Network Adapter driver.

The iscsiadm and iscsid commands depended on files in /usr, but did not require that /usr was mounted when they were used. This resulted in failures without useful error messages when the user attempted to use these commands when /usr was not mounted. This issue has been corrected, and these failures no longer occur.

Starting or stopping the iSCSI service while accessing the root partition directly through an iSCSI disk could cause iSCSI to become unresponsive and incorrect status information to be reported. Attempting to stop the iSCSI service in this circumstance now warns that iSCSI cannot be shut down while Root is on an iSCSI disk, and all statuses are reported correctly.

The brcm_iscsiuio usage message displayed in response to the brcm_iscsiuio --help command contained two unsupported options: --foreground and --pid. The man page omitted five supported options: --debug, --help, -h, -p and --version. The unsupported options have been removed from the usage message, and all supported options have been added to the brcm_iscsiuio man page.

The iscsiadm usage message displayed in response to the iscsiadm --help command omitted 24 supported options. Additionally, the iscsiadm man page omitted one supported option (--host) and contained one unsupported option (--info). These errors have now been corrected.

iscsiadm did not accept host names or aliases as valid values for the --portal argument when in "node" mode. This resulted in failure, because iscsiadm expected the value returned during discovery as the value for --portal. iscsiadm now attempts to match a host name to the IP address returned during discovery, so this issue no longer occurs.

If debug message logging was disabled, the iSCSI daemon failed to set the socket priority according to the Data Center Bridging application priority setting, which resulted in packets being sent with the default priority incorrectly. Socket priority is now set based on the Data Center Bridging application priority setting in this situation.

When iscsiadm failed or exited incorrectly, it did not output useful error codes. Meaningful error codes now exist for these situations, and are described further in the iscsiadm man page.

Support for Data Center Bridging has been added to the iSCSI driver.

brcm_iscsiuio provides the ARP and DHCP functionality to offload iSCSI functionality. Support has been added for IPv6, VLAN, and several new Broadcom network cards.
