Dynamic zones with dnssec-policy could not be thawed because KASP
zones were considered always dynamic. But a dynamic KASP zone should
also check whether updates are disabled.
The transport should also be detached when we skip a master, otherwise
named will crash when sending a SOA query to the next master over TLS,
because the transport must be NULL when we enter
'dns_view_gettransport'.
When we query the resolver for a domain name that is in the same zone
for which is already one or more fetches outstanding, we could
potentially hit the fetch limits. If so, recursion fails immediately
for the incoming query and if serve-stale is enabled, we may try to
return a stale answer.
If the resolver is also is authoritative for the parent zone (for
example the root zone), first a delegation is found, but we first
check the cache for a better response.
Nothing is found in the cache, so we try to recurse to find the
answer to the query.
Because of fetch-limits 'dns_resolver_createfetch()' returns an error,
which 'ns_query_recurse()' propagates to the caller,
'query_delegation_recurse()'.
Because serve-stale is enabled, 'query_usestale()' is called,
setting 'qctx->db' to the cache db, but leaving 'qctx->version'
untouched. Now 'query_lookup()' is called to search for stale data
in the cache database with a non-NULL 'qctx->version'
(which is set to a zone db version), and thus we hit an assertion
in rbtdb.
This crash was introduced in 'main' by commit
8bcd7fe69e.
This commit completes the support for DNS-over-HTTP(S) built on top of
nghttp2 and plugs it into the BIND. Support for both GET and POST
requests is present, as required by RFC8484.
Both encrypted (via TLS) and unencrypted HTTP/2 connections are
supported. The latter are mostly there for debugging/troubleshooting
purposes and for the means of encryption offloading to third-party
software (as might be desirable in some environments to simplify TLS
certificates management).
The 'key_init()' function is used to initialize a state file for keys
that don't have one yet. This can happen if you are migrating from a
'auto-dnssec' or 'inline-signing' to a 'dnssec-policy' configuration.
It did not look at the "Inactive" and "Delete" timing metadata and so
old keys left behind in the key directory would also be considered as
a possible active key. This commit fixes this and now explicitly sets
the key goal to OMNIPRESENT for keys that have their "Active/Publish"
timing metadata in the past, but their "Inactive/Delete" timing
metadata in the future. If the "Inactive/Delete" timing metadata is
also in the past, the key goal is set to HIDDEN.
If the "Inactive/Delete" timing metadata is in the past, also the
key states are adjusted to either UNRETENTIVE or HIDDEN, depending on
how far in the past the metadata is set.
