New Features
Added a new include file with function typedefs for the DLZ “dlopen” driver. [RT #23629]
Added a tool able to generate malformed packets to allow testing of how named handles them. [RT #24096]
Security Fixes
- If `named` is configured with a response policy zone (RPZ) and a query of type RRSIG is received for a name configured for RRset replacement in that RPZ, it will trigger an INSIST and crash the server. RRSIG. [RT #24280]
- `named`, set up to be a caching resolver, is vulnerable to a user querying a domain with very large resource record sets (RRSets) when trying to negatively cache the response. Due to an off-by-one error, caching the response could cause `named` to crash. [RT #24650] [CVE-2011-1910]
- Using Response Policy Zone (RPZ) to query a wildcard CNAME label with QUERY type SIG/RRSIG, it can cause `named` to crash. Fix is query-type independent. [RT #24715]
- Using Response Policy Zone (RPZ) with DNAME records and querying the subdomain of that label can cause `named` to crash. Now logs that DNAME is not supported. [RT #24766]
- Change #2912 populated the message section in replies to UPDATE requests, which some Windows clients wanted. This exposed a latent bug that allowed the response message to crash `named`. With this fix, change 2912 has been reduced to copy only the zone section to the reply. A more complete fix for the latent bug will be released later. [RT #24777]
Feature Changes
Improved the startup time for an authoritative server with a large number of zones by making the zone task table of variable size rather than fixed size. This means that authoritative servers with lots of zones will be serving that zone data much sooner. [RT #24406]
Merged in the NetBSD ATF test framework (currently version 0.12) for development of future unit tests. Use configure –with-atf to build ATF internally or configure –with-atf=prefix to use an external copy. [RT #23209]
Added more verbose error reporting from DLZ LDAP. [RT #23402]
The DLZ “dlopen” driver is now built by default, no longer requiring a configure option. To disable it, use “configure–without-dlopen”. (Note: driver not supported on win32.) [RT#23467]
Replaced compile time constant with STDTIME_ON_32BITS. [RT #23587]
Make –with-gssapi default for ./configure. [RT #23738]
