1.23.1. RHBA-2010:0664: bug fix update

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.

1.23.2. RHBA-2010:0612: bug fix update

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, moving the server from communication-interrupted into partner-down state didn't force dhcpd to take over the partner's leases. With this update, a partner-down failover server no longer sends 'peer holds all free leases' if it is able to newly-allocate one of the peer's leases.
All users of dhcp are advised to upgrade to these updated packages, which resolve this issue.
