[Xorp-hackers] Announcing XORP Release 1.3

[Atanu Ghosh]

On behalf of the entire XORP team, I'm delighted to announce the XORP
1.3 Release, which is now available from <http://www.xorp.org>.

The major new features with this release are:

* IGMPv3 (RFC 3376)

* MLDv2 (RFC 3810)

In addition, this release contains numerous bug fixes.

There are still a number of non-critical bugs that we know about which
will not be addressed until the 1.4 release; these are documented in
the XORP Bugzilla database <http://www.xorp.org/bugzilla/index.cgi>.

In general, to test XORP, we run automated regression tests on a daily
basis with various operating systems and compilers. We also run a
number of PCs as XORP routers. We have enabled as many protocols as
feasible on those routers to test protocol interactions (for example a
BGP IPv6 multicast feed being used by PIM-SM). In addition, automated
scripts are run to externally toggle BGP peerings. Finally, we have
automated scripts that interact directly with the xorpsh to change the
configuration settings.

We have put significant effort into testing but obviously we have not
found all the problems. This is where you can help us to make XORP
more stable, by downloading and using it!

As always we'd welcome your comments - xorp-users at xorp.org is the
right place for general discussion, and private feedback to the XORP
core team can be sent to feedback at xorp.org.

		XORP RELEASE NOTES

This file contains XORP release notes (most recent releases first).

Release 1.3 (2006/08/02)
=========================
  ALL:
    - Numerous improvements, bug fixes and cleanup.

    - XORP now builds on Linux Fedora Core5, DragonFlyBSD-1.4,
      FreeBSD-6.1.

    - Implementation of IGMPv3 (RFC 3376) and MLDv2 (RFC 3810).
      Those are necessary to complete the Source-Specific Multicast
      support.

  CONFIGURATION:
    - Addition of new OSPF configuration statement as part of the MD5
      keys:

      * max-time-drift: u32 (default to 3600, i.e., 1 hour)

      It is used to set the maximum time drift (in seconds) among all
      OSPF routers. The allowed values are in the range [0--65535]. If
      the value is 65535, the time drift is unlimited.

    - The following statements for configuring static routes have been
      deprecated:
      route4, route6, interface-route4, interface-route6, mrib-route4,
      mrib-route6, mrib-interface-route4, mrib-interface-route6.

      The new replacement statements are:
      route, interface-route, mrib-route, mrib-interface-route.

      Each of the new statements can be used to configure either IPv4Net
      or IPv6Net route.

    - The following statements for configuring RIP and RIPng have been
      renamed:

      * route-expiry-secs -> route-timeout

      * route-deletion-secs -> deletion-delay

      * table-request-secs -> request-interval

      * interpacket-delay-msecs -> interpacket-delay

    - The following statements for configuring RIP and RIPng random
      intervals have been replaced:

      * triggered-update-min-secs and triggered-update-max-secs with
        triggered-delay and triggered-jitter

      * table-announce-min-secs and table-announce-max-secs with
        update-interval and update-jitter

      Previously, each interval was specified as [foo-min, foo-max].
      Now each interval is specified as
      [foo - foo * jitter / 100, foo + foo * jitter / 100]
      where "jitter" is specified as a percentage (an integer in the
      interval [0, 100]) of the value of "foo".

    - The "version" statement for configuring an IGMP interface/vif
      allows values in the range [1-3]. Previously, the allowed range
      was [1-2].

    - The "version" statement for configuring a MLD interface/vif allows
      values in the range [1-2]. Previously, the allowed range was [1-1].

    - The following statement for configuring PIM-SM (pimsm4 and pimsm6)
      has been renamed:

      interval-sec -> interval

    - If a "then" policy block contains "accept" or "reject" statement,
      now all statements inside the "then" block are evaluated
      regardless of their position.

    - Addition of a new "exit" operational mode command that is
      equivalent to the "quit" operational mode command.

    - The "create" and "set" configuration commands are merged, so now
      the new "set" command can be used for setting values and for
      creating new configuration nodes. For backward compatibility,
      the obsoleted "create" command is preserved as an alias for the
      new "set" command, though it may be removed in the future.

  LIBXORP:
    - Few bug fixes in the RefTrie implementation.

  LIBXIPC:
    - Minor improvement in parsing XRL requests.

  LIBFEACLIENT:
    - No significant changes.

  XRL:
    - No significant changes.

  RTRMGR:
    - Various bug fixes.

  XORPSH:
    - Previously, the "commit" command was not available in
      configuration mode if there were no pending configuration changes.
      Now the "commit" command is always available, but the following
      message will be printed instead:
        "No configuration changes to commit."

    - Various bug fixes.

  POLICY:
    - Various bug fixes.

  FEA/MFEA:
    - Bug fix in transmitting large packets on Linux when using IP raw
      sockets.

    - Linux-related netlink socket code refactoring and bug fix.

    - Bug fix in obtaining the incoming interface for raw packets
      (in case of *BSD).

    - Bug fix in parsing the ancillary data from recvmsg().

    - Accept zeroed source addresses of raw packets, because of
      protocols like IGMPv3.

    - Bug fix in restoring kernel routes that were automatically removed
      when the MAC address or MTU on an interface is modified.

    - Bug fix in processing IPv4 raw packets if they contain an IP option
      with a bogus option length.

  RIB:
    - Several bug fixes and improvements.

  RIP:
    - Various bug fixes in the MD5 authentication support.

    - Remove route flap when applying/deleting RIP-related import
      policies.

    - Fix an issue with INFINITY cost routes that might be bounced
      indefinitely between two XORP routers.

  OSPF:
    - Various bug fixes in the MD5 authentication support.

  BGP:
    - Prefix limits on a per peer basis.

    - Various bug fixes.

  STATIC_ROUTES:
    - No significant changes.

  MLD/IGMP:
    - Implementation of IGMPv3 (RFC 3376) and MLDv2 (RFC 3810).

    - Unification of the IGMP and MLD execution path.

  PIM-SM:
    - Bug fix related to the SPT switch (the bug is *BSD specific).

    - Use the RPF interface toward the BSR when transmitting a Cand-RP
      Advertisement message. Previously the first interface that is UP
      was chosen.

    - Use the RPF interface toward the RP when transmitting PIM Register
      messages toward the RP. Previously the interface of the directly
      connected source was chosen.

  FIB2MRIB:
    - No significant changes.

  CLI:
    - Bug fix related to tracking the window size when it is resized.

  SNMP:
    - No significant changes.
