The Unix Domain Sockets support in BIND 9 has been completely disabled
since BIND 9.18 and it has been a fatal error since then. Cleanup the
code and the documentation that suggest that Unix Domain Sockets are
supported.
When using automated DNSSEC management, it is required that the zone
is dynamic, or that inline-signing is enabled (or both). Update the
checkconf code to also allow inline-signing to be enabled within
dnssec-policy.
These two configuration options worked in conjunction with 'auto-dnssec'
to determine KSK usage, and thus are now obsoleted.
However, in the code we keep KSK processing so that when a zone is
reconfigured from using 'dnssec-policy' immediately to 'none' (without
going through 'insecure'), the zone is not immediately made bogus.
Add one more test case for going straight to none, now with a dynamic
zone (no inline-signing).
There are times where you want named-checkconf to check whether the
dnssec-policies should be constrained by the cryptographic algorithms
supported by the operation system or to just accept all possible
algorithms. This provides a mechanism to make that selection.
These options and zone type were created to address the
SiteFinder controversy, in which certain TLD's redirected queries
rather than returning NXDOMAIN. since TLD's are now DNSSEC-signed,
this is no longer likely to be a problem.
The deprecation message for 'type delegation-only' is issued from
the configuration checker rather than the parser. therefore,
isccfg_check_namedconf() has been modified to take a 'nodeprecate'
parameter to suppress the warning when named-checkconf is used with
the command-line option to ignore warnings on deprecated options (-i).
which can be a size or the string 'unlimited' but not the string
'default'. This is used for max-cache-size and max-journal-size,
and obsoletes the special check for 'default' in check.c.
