RHBA-2014:1580 - Bug Fix Advisory

Topic

Updated iscsi-initiator-utils packages that fix several bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

Description

The iscsi-initiator-utils packages provide the server daemon for the Internet
Small Computer System Interface (iSCSI) protocol, as well as the utility
programs used to manage it. iSCSI is a protocol for distributed disk access
using SCSI commands sent over Internet Protocol (IP) networks.

The iSCSI UserSpace I/O driver (iscsiuio) has been updated to upstream version
0.7.8.2, which provides a number of bug fixes and enhancements over the previous
version. (BZ#1054587)

The QLogic ala4xxx drivers have been updated to the latest upstream version,
which provides a number of bug fixes and enhancements over the previous version.
(BZ#1053374, BZ#1140326)

This update also fixes the following bugs:

• Due to changes in the addressing of inter-process communication (IPC) sockets,

updating the isciadm administration utility caused it to be incompatible with
the already-running iscsid processes. As a consequence, iscsiadm could no longer
communicate with the running iscsid processes after the update. This update adds
a retroactive compatibility IPC mode, which automatically triggers when a new
IPC socket fails to connect. As a result, iscsiadm can now correctly be used to
control pre-existing iscsid processes after an update. (BZ#0009299, BZ#1052361)

• Prior to this update, the uip_reset() function was in some cases called with

an invalid ustack address. As a consequence, the iscsiuio process was terminated
unexpectedly with a segmentation fault. With this update, the ustack address
calling uip_reset() has been fixed and the described crash no longer occurs.
(BZ#1132490)

• Prior to this update, the iscsid daemon could not handle more than 31 iSCSI

asynchronous events. Consequently, when performing an iSCSI operation with 32 or
more target protocol data units, iscsid entered an infinite loop and became
unresponsive. With this update, iscsid can properly handle more than 31 iSCSI
asynchronous events, and the described hang no longer occurs. (BZ#1076344)

Users of iscsi-initiator-utils are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.
