*** From dhcp-announce -- To unsubscribe, see the end of this message. ***<br><br><br>ISC DHCP 4.1.0a1 is now available for download.<br><br>This is FIRST ALPHA release of ISC DHCP 4.1.0, a feature release focused<br>on expanding support for DHCPv6. A list of changes in this release has<br>
been appended to this message. For a full list of changes since any<br>historical version, please consult the RELNOTES file in the software<br>distribution, or on our website:<br><br> <a href="http://www.isc.org/sw/dhcp/dhcp4_1.php" target="_blank">http://www.isc.org/sw/dhcp/dhcp4_1.php</a><br>
<br>ISC DHCP 4.1.x will have several new DHCPv6 features that were not in<br>DHCP 4.0.x. These will include:<br><br>- Support for the rapid-commit option on the client side<br><br>- Prefix Delegation support<br><br>- IA_TA address support<br>
<br>- A basic DHCPv6 relay agent, dhcrelay6<br><br>There are a number of DHCPv6 limitations and features missing in this<br>release, which will be addressed in the future:<br><br>- Only Solaris, Linux, FreeBSD, NetBSD, and OpenBSD are supported.<br>
<br>- Only a single address is supported per IA.<br><br>- DHCPv6 includes human-readable text in status code messages. These<br> should be configurable, and probably localized via gettext() or the<br> like.<br><br>- The "host-identifier" option is limited to a simple token.<br>
<br>- The client and server can only operate DHCPv4 or DHCPv6 at a time,<br> not both. To use both protocols simultaneously, two instances of the<br> relevant daemon are required, one with the '-6' command line option.<br>
<br>For information on how to install, configure and run this software, as<br>well as how to find documentation and report bugs, please consult the<br>README file.<br><br>ISC DHCP uses standard GNU configure for installation. Please review the<br>
output of "./configure --help" to see what options are available.<br><br>The system has only been tested on Linux, FreeBSD, and Solaris, and may not<br>work on other platforms. Please report any problems and suggested fixes to<br>
<<a href="mailto:dhcp-users@isc.org">dhcp-users@isc.org</a>>.<br><br><br> Changes since 4.0.0 (new features)<br><br>- Added DHCPv6 rapid commit support.<br><br>- Added explicit parser support for zero-length DHCP options, such as<br>
rapid-commit, via format code 'Z'.<br><br>- It's now possible to update the "ends" field of a lease with OMAPI.<br> This is useful if you want not only to release a lease, but also make<br> it available for reuse right away. Hat tip to Christof Chen.<br>
<br>- Fixed definition of the iaaddr hash functions to use the correct<br> functions when referencing and dereferencing memory.<br><br>- Some definitions not in phase with the IANA registry were updated.<br><br>- Allocated interface IDs are better controlled ('u' bit set to zero,<br>
reserved IDs avoided).<br><br>- Unicast options are taken into account only for RENEWs.<br><br>- NoAddrsAvail answers to SOLICITs are always ADVERTISEs even when a SOLICIT<br> carries a rapid-commit option.<br><br>- Return in place of raise an impossible condition when one tries to release<br>
an empty active lease.<br><br>- Timer granularity is now 1/100s in the DHCPv6 client.<br><br>- The dhclient-script was updated to create a host route for the default<br> gateway if the supplied subnet mask for an IPv4 address was a /32. This<br>
allows the client to work in 'captive' network environments, where the<br> operator does not want clients to crosstalk directly.<br><br>- MINUS tokens should be parseable again.<br><br>- Multiple (up to "delayed-ack x;" maximum) DHCPv4 packets are now queued and<br>
released in bursts after single fsync() events when the upper limit is<br> reached or if the receiving sockets go dry. The practical upshot is<br> that fsync-coupled server performance is now multiplicitively increased.<br>
The default delayed ack limit is 28. Thanks entirely to a patch from<br> Christof Chen.<br><br> Changes since 4.0.0 (bug fixes)<br><br>- DHCP now builds on AIX.<br><br>- Exit with warning when DHCPv6-specific statements are used in the<br>
config file but -6 is not specified.<br><br>- Fixed "--version" flag in dhcrelay<br><br>- The 'min-secs' configuration parameter's log message has been updated to<br> be more helpful.<br><br>- The warning logged when an address range doesn't fit in the subnets<br>
they were declared has been updated to be more helpful and identify the<br> typo in configuration that created the spanning addresses.<br><br>- A bug in failover pool rebalancing that caused POOLREQ message ping-pongs<br>
was repaired.<br><br>- A flaw in failover pool rebalancing that could cause POOLREQ messages to<br> be sent outside of the min-balance/max-balance scheduled intervals has<br> been repaired.<br><br>- A cosmetic bug during potential-conflict recovery that caused the peer's<br>
'conflict-done' state message to be logged as 'unknown-state' has been<br> repaired. It is now logged correctly.<br><br>- A bug was fixed where the 'giaddr' may be used to find the client's subnet<br>
rather than its own 'ciaddr'.<br><br>- A log message was introduced to clarify the situation where a failover<br> 'address' parameter (the server's local address) did not resolve to an<br> IPv4 address.<br>
<br>- The minimum site code value was set to 224 in 3.1.0 to track RFC3942. This<br> broke a lot of legacy site local configurations. The new code in place will<br> track site local space minimum option codes and logs a warning to encourage<br>
updates and exploration of site local code migration problems. Option<br> codes less than 128 in site local spaces remain inaccessible.<br><br>- A possible relay agent option bug was repaired where random server<br> initialization state may have been used to signal the relay agent<br>
information options sub-option code for the 'END' of the option space.<br><br>- Fixes to allow code to compile and run on Solaris 9.<br><br>- Fixes to allow code to compile on Mac OS X Leopard (10.5).<br><br>- When server is configured with options that it overrides, a warning is<br>
issued when the configuration file is read, rather than at the time the<br> option is overridden. This was important, because the warning was given<br> every time the option was overridden, which could create a lot of<br>
unnecessary logging.<br><br>- Fixed a compilation problems on platforms that define a value for FDDI,<br> which conflicts with a dhcp configuration syntax token by the same name.<br><br>- When a failover server suspects it has encountered a peer running a<br>
version 3.0.x failover server, a warning that the failover wire protocol<br> is incompatible is printed.<br><br>- The failover server no longer issues a floating point error if it encounters<br> a previously undefined option code.<br>
