RHBA-2010:0042 - dhcp bug fix update

Synopsis

dhcp bug fix update

Type/Severity

Bug Fix Advisory

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 This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
