Security Fixes
  • BIND 9 nameservers performing recursive queries could cache an invalid record and subsequent queries for that record could crash the resolvers with an assertion failure. [RT #26590] [CVE-2011-4313]

New Features

  • Add a 'named -U' option to set the number of UDP listener threads per interface. [RT #26485]
  • dnssec-signzone: "-f -" prints to stdout; "-O full" option prints in single-line-per-record format.  [RT #20287]
  • Add a configuration switch "dnssec-lookaside 'no'" to set explicitly the current default behavior.  [RT #24858]
  • 'rndc querylog' can now be given an on/off parameter instead of only being used as a toggle. [RT #18351]
  • When the server logs messages about the state of recursive client processing, it will include the name the client had requested in the log messages, to make it easier to identify problems when they occur. Such log messages will now look similar to this one: 03-Nov-2011 14:14:44.981 client 10.53.0.7#49775 (www.example.com): send

Bug Fixes

  • Change #3186 was incomplete; dns_db_rpz_findips() could fail to set the database version correctly, causing an assertion failure. [RT #26180]
  • Correct a behavior introduced in 9.9.0a3 whereby 'rndc recursing' could cause a core dump. [RT #26495]
  • resolver.c:validated() was not thread-safe. [RT #26478]
  • Correct a situation in rbtdb.c: where failure to remove a node from the deadnodes list prior to adding a reference to it could lead to a possible assertion failure. [RT #23219] 
  • Canceling the oldest query due to recursive-client overload could trigger an assertion failure. [RT #26463]
  • NOEDNS caching on timeout was too agressive.  [RT #26416]
  • Clarify the error message reported when the config parser cannot open a file.  [RT #22263]
  • A query structure could be used after being freed. [RT #22208]
  • zone.c:zone_refreshkeys() could fail to detach references correctly when errors occurred, causing a hang on shutdown. [RT #26372]
