RHBA-2013:0454 - Bug Fix Advisory

Topic

Updated python-ethtool packages that fix four bugs and add one enhancement are
now available for Red Hat Enterprise Linux 6.

Description

The python-ethtool package makes the ethtool kernel interface available within
the Python programming environment to allow querying and changing of Ethernet
card settings, such as speed, port, auto-negotiation, and PCI locations.

This update fixes the following bugs:

• With this update, a typographical error has been corrected in the output of

the "pethtool --help" command. (BZ#692028)

• Prior to this update, a memory leak occurred when the get_active_devices() and

get_interfaces_info() functions were called repeatedly. This bug has been fixed
and the memory leak no longer occurs in the described scenario. (BZ#698125)

• Due to a bug in the command-line parser, the pifconfig utility did not accept

an interface as an argument if specified on the command line. Consequently, the
utility displayed all interfaces rather than just information about the
specified interface as was expected. The bug in the parser has been fixed and
pifconfig now correctly parses passed arguments. (BZ#714753)

• Previously, if one network interface controller (NIC) had more IP addresses,

only the first address was reported multiple times. With this update, the
get_ipv4_addresses() method has been implemented to report all IP addresses on
the NIC. (BZ#759150)

This update also adds the following enhancement:

• With this update, support for devices configured with IPv6 has been added to

the pifconfig utility. (BZ#698192)

All users of python-ethtool are advised to upgrade to these updated packages,
which fix these bugs and add this enhancement.
