Bug Fix Advisory dhcp bug fix update

Advisory: RHBA-2010:0664-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2010-08-31
Last updated on: 2010-08-31
Affected Products: RHEL Desktop Workstation (v. 5 client)
Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)

Details

An updated dhcp package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

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.

These updated packages provide a fix for the following bug:

* previously, dhcpd sometimes started to give "INIT" clients new leases rather
than presently active ones. That led to premature exhaustion of available leases
for new clients.
With this update, the server's "by client-id" and "by hardware address" hash
table lists are sorted according to the preference to re-allocate that lease to
returning clients. This should eliminate pool starvation problems.

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


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
