Topic

A dhcp update that fixes one memory leak is now available.

Description

The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows
individual devices on an IP network to get their own network configuration
information, including an IP address, a subnet mask, and a broadcast
address. The dhcp package provides a relay agent and ISC DHCP service
required to enable and administer DHCP on a network.

This update applies the following updates:

  • a memory leak in the load_balance_mine() function caused dhcpd, the dhcp

server, to leak approximately 20-30 octets per DHCPDISCOVER packet when the
server was configured for failover and failover was in a normal state. This
particular leak has been closed with this update. (BZ#552211)

Note: depending on the specific DHCP setup on a given system, other memory
leaks may still present. Please file a separate bug if DHCP appears to leak
memory after applying this update.

All dhcp users should to apply this update which closes this memory leak.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
