Bug Fixes

BZ#1113978

Previously, when the XML configuration for an interface enabled dynamic host configuration protocol (DHCP) for IPv6, the netcf library erroneously set the variable named "DHCPV6" in the ifcfg configuration file instead of "DHCPV6C". The underlying source code has been patched, and netcf now passes the correct "DHCPV6C" option to ifcfg.

BZ#1116314

Prior to this update, when requested to configure an interface with an IPv4 netmask of 255.255.255.255, the netcf library logged an error as the interface configuration was rejected. This update fixes the netmask for the 32-bit interface prefix, and netcf now configures IPv4 interfaces successfully.

BZ#1208897

Due to a parsing error, the ifcfg files with comments starting anywhere beyond column 1 or multiple variables on a single line caused the netcf library to generate errors when attempting to list host interfaces. The parsing error has been fixed, and any tool using netcf now lists active interfaces as expected.

BZ#1208894

When multiple static IPv6 addresses were specified in an interface configuration, an extra set of quotes appeared in the IPV6ADDR_SECONDARIES entry in the generated configuration file. This update removes extraneous single quotes from IPV6ADDR_SECONDARIES, thus fixing this bug.

BZ#1165966

Due to a denial of a service flaw in the netcf library, a specially crafted interface name previously caused applications using netcf, such as the libvirt daemon, to terminate unexpectedly. An upstream patch has been applied to fix this bug, and applications using netcf no longer crash in the aforementioned situation.
