RHBA-2018:3658 - Bug Fix Advisory

Topic

Updated nbdkit packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 7.

Description

Network Block Device (NBD) is a protocol for accessing hard disks and other disk-like devices over the network. The nbdkit toolkit utilizes NBD to create servers with minimal dependencies. The package contains plug-in support for the C and Python programming languages.

This update fixes the following bug:

• Previously, the nbdkit package was configured with an incorrect priority for the TLS protocol. As a consequence, TLS connections connections to the NBD server did not work. This update fixes the TLS priority in nbdkit, which ensures proper functionality of TLS connections. (BZ#1632789)

In addition, this update adds the following enhancement:

• The Python plug-in for the nbdkit tool suite has been enhanced to print full stack traces when errors occur in Python scripts. As a result, certain error messages that can be generated when converting a virtual machine to Red Hat Virtualization using the virt-v2v utility now provide significantly more information. (BZ#1647740)

Users of nbdkit are advised to upgrade to these updated packages, which fix this bug and this enhancement.
