8.44. dhcp
Updated dhcp packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
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 packages provide a relay agent and ISC DHCP service required to enable and administer DHCP on a network.
Bug Fixes
- BZ#1015997
- When a packet with checksum having the value of 0xffff was received by the dhcpd daemon, the packet was discarded. With this update, checksum with value 0xffff is perceived as correct, and the packet is now processed as intended.
- BZ#1053155
- Previously, the user could not run IPv6 version of the dhcrelay service, because there was no such initiation script. To fix this bug, the initiation script of dhcrelay has been added, and the user can now run service for IPv6 version of dhcrelay.
- BZ#1053431
- When IPv6 version of the dhcpd daemon served too many requests, the /var/lib/dhcpd/dhcpd.leases file grew uncontrollably in size. As a consequence, dhcpd refused to restart with the following error message:file is too long to bufferAn upstream patch has been backported to fix this bug, and dhcpd for IPv6 now rotates /var/lib/dhcpd/dhcpd.leases to prevent it from growing.
- BZ#1064416
- When using ISC DHCP server and clients on Infiniband cards (IPoIB), the hardware address, called GUID, did not appear in logs. This update adds GUIDs to the logs for IPoIB.
- BZ#1067142
- Every time the dhcpd daemon started, the ownership of the /var/lib/dhcpd/dhcpd.leases file was changed from dhcpd:dhcpd to root:root. A Fedora patch has been backported to fix this bug, and the ownership of /var/lib/dhcpd/dhcpd.leases no longer changes.
- BZ#1099698
- When having failover configuration of the dhcpd daemon and using very long lease times for clients, the following error was returned when starting dhcpd:unable to write leaseA patch has been applied to fix this bug, and error messages no longer appear in logs.
- BZ#1102662
- Previously, when starting the dhcpd daemon or the dhcrelay agent, the user specified the name of the network interface. If longer than 15 characters, dhcpd or dhcrelay terminated unexpectedly with the following error message:*** buffer overflow detected ***A patch has been backported to fix this bug, and dhcpd or dhcrelay now exit gracefully with a new error message informing the user that the interface name is too long.
Users of dhcp are advised to upgrade to these updated packages, which fix these bugs.
