The status shows whether 28 1.1.1.1.4.2 perseant :iscman:`named` can toggle memory profiling, and whether the server is built 29 1.1.1.1.4.2 perseant with jemalloc. :gl:`#4759` 30 1.1.1.1.4.2 perseant 31 1.1.1.1.4.2 perseant - Add support for multiple extended DNS errors. 32 1.1.1.1.4.2 perseant 33 1.1.1.1.4.2 perseant The Extended DNS Error (EDE) mechanism may raise errors 34 1.1.1.1.4.2 perseant during a DNS resolution. :iscman:`named` is now able to add up to three EDE 35 1.1.1.1.4.2 perseant codes in a DNS response. If there are duplicate error codes, only 36 1.1.1.1.4.2 perseant the first one is part of the DNS response. :gl:`#5085` 37 1.1.1.1.4.2 perseant 38 1.1.1.1.4.2 perseant - Print the expiration time of stale records. 39 1.1.1.1.4.2 perseant 40 1.1.1.1.4.2 perseant BIND now prints the expiration time of any stale RRsets in the cache dump. 41 1.1.1.1.4.2 perseant 42 1.1.1.1.4.2 perseant Bug Fixes 43 1.1.1.1.4.2 perseant ~~~~~~~~~ 44 1.1.1.1.4.2 perseant 45 1.1.1.1.4.2 perseant - Recently expired records could be returned with a timestamp in future. 46 1.1.1.1.4.2 perseant 47 1.1.1.1.4.2 perseant Under rare circumstances, an RRSet that expired at the time of the 48 1.1.1.1.4.2 perseant query could be returned with a TTL in the future. This has been 49 1.1.1.1.4.2 perseant fixed. 50 1.1.1.1.4.2 perseant 51 1.1.1.1.4.2 perseant As a side effect, the expiration time of expired RRSets is no longer 52 1.1.1.1.4.2 perseant returned in a cache dump. :gl:`#5094` 53 1.1.1.1.4.2 perseant 54 1.1.1.1.4.2 perseant - YAML string not terminated in negative response in delv. 55 1.1.1.1.4.2 perseant 56 1.1.1.1.4.2 perseant :gl:`#5098` 57 1.1.1.1.4.2 perseant 58 1.1.1.1.4.2 perseant - Fix a bug in :iscman:`dnssec-signzone` related to keys being offline. 59 1.1.1.1.4.2 perseant 60 1.1.1.1.4.2 perseant When :iscman:`dnssec-signzone` was called on an already-signed 61 1.1.1.1.4.2 perseant zone and the private key file was unavailable, a signature that needed 62 1.1.1.1.4.2 perseant to be refreshed was dropped without being able to generate a 63 1.1.1.1.4.2 perseant replacement. This has been fixed. :gl:`#5126` 64 1.1.1.1.4.2 perseant 65 1.1.1.1.4.2 perseant - Apply the memory limit only to ADB database items. 66 1.1.1.1.4.2 perseant 67 1.1.1.1.4.2 perseant Under heavy load, a resolver could exhaust the memory available for 68 1.1.1.1.4.2 perseant storing the information in the Address Database (ADB), effectively 69 1.1.1.1.4.2 perseant discarding previously stored information in the ADB. The memory used to 70 1.1.1.1.4.2 perseant retrieve and provide information from the ADB is no longer subject to 71 1.1.1.1.4.2 perseant the same memory limits that are applied to 72 1.1.1.1.4.2 perseant the Address Database. :gl:`#5127` 73 1.1.1.1.4.2 perseant 74 1.1.1.1.4.2 perseant - Avoid unnecessary locking in the zone/cache database. 75 1.1.1.1.4.2 perseant 76 1.1.1.1.4.2 perseant Lock contention among many worker threads referring to the 77 1.1.1.1.4.2 perseant same database node at the same time is now prevented. This improves zone and 78 1.1.1.1.4.2 perseant cache database performance for any heavily contended database nodes. 79 1.1.1.1.4.2 perseant :gl:`#5130` 80 1.1.1.1.4.2 perseant 81 1.1.1.1.4.2 perseant - Fix reporting of Extended DNS Error 22 (No Reachable Authority). 82 1.1.1.1.4.2 perseant 83 1.1.1.1.4.2 perseant This error code was previously not reported in some applicable 84 1.1.1.1.4.2 perseant situations. This has been fixed. :gl:`#5137` 85 1.1.1.1.4.2 perseant 86
