RHBA-2012:0193 - libdhcp bug fix update

Synopsis

libdhcp bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated libdhcp packages that fix three bugs are now available for Red Hat Enterprise Linux 5.

Description

libdhcp enables programs to invoke and control the Dynamic Host Configuration Protocol (DHCP) clients: the Internet Software Consortium (ISC) Internet Protocol version 4 (IPv4) DHCP client library, libdhcp4client, and the Internet Protocol version 6 (IPv6) DHCPv6 client library, libdhcp6client.

This update fixes the following bug:

  • Prior to this update, interface card (NIC) indexes were interrupted internally due to a cache iteration error in libdhcp. The update ensures that the interfaces are enumerated sequentially so that there are no index gaps. Now, libdhcp works as expected. (BZ#599633)

  • Prior to this update, interfaces that were enabled at boot time had, under certain circumstances, invalid flags like DEBUG PROMISC or ALLMULTI. This update no longer passes these flags. (BZ#616865)

  • Prior to this update, the libdhcp timeout was not correctly passed. As a result certain requests always stopped after 60 seconds even if the corresponding command line option allowed for more time. This update correctly passes the dhcp timeout value to the dhcp client library. This update is a dependency of BZ#736515 and BZ#737161. (BZ#737155)

All users of libdhcp are advised to upgrade to these updated packages, which fix these bugs.
