RHBA-2009:1333 - Bug Fix Advisory

Topic

Updated libdhcp packages that fix various bugs are now available.

Description

libdhcp enables programs to invoke and control the Dynamic Host
Configuration Protocol (DHCP) clients: the Internet Software Consortium
(ISC) IPv4 DHCP client library, libdhcp4client, and the IPv6 DHCPv6 client
library, libdhcp6client. libdhcp also provides network interface
configuration services for network parameter auto-configuration with DHCP.

These updated libdhcp packages fix the following problems:

• libdhcp did not allow for some situations where a static network

configuration was specified. Specifically, when a configuration without a
DHCP server was specified during installation, the network interface was
not activated. This would preclude installations through FTP and HTTP.
Libdhcp now activates the interface when a static configuration is
specified, even when no DHCP server is present so that network-based
installations are possible. (BZ#233066)

• previously, the method used by libdhcp to build a list of network

interfaces available on a system could accommodate a maximum of 86
interfaces. As a consequence, attempts to perform network-based
installations through interfaces eth86 and higher would fail. libdhcp now
uses libnl to build a list of valid interfaces and therefore is no longer
limited to the first 86 that it finds. Network-based installations are
therefore possible on a wider range of hardware and network configurations.
(BZ#444919)

Interfaces using static network configuration are properly handled during
installation.

• The system will now see all available network interfaces in the system

during installation, rather than stopping at eth85.

All users of libdhcp are advised to upgrade to these updated packages,
which resolve this issue.
