Subject: chg: usr: Introduce a minimum TTL for cached delegations
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=6588c5f304ef54190e461543fafe3fedd97bb419;p=thirdparty%2Fbind9.git

chg: usr: Introduce a minimum TTL for cached delegations

Delegations are now cached with a minimum TTL of 60 seconds by default. Any NS record or A/AAAA glue record with a TTL below this threshold will be raised to 60 seconds.

A new configuration option `min-delegation-ttl` has been added to adjust this limit, or disable it by setting the value to `0`. The corresponding `max-delegation-ttl` option allows the user to configure a maximum TTL for delegations; it is disabled by default.

Closes #6031

Merge branch '6031-delegdb-ttl' into 'main'
