There should be 2 keys with the same key id after the numerically
lower one is revoked (serial space arithmetic). The DS points
at the non-revoked key so validation should still succeed.

messages indicating the reason for a fallback to AXFR (i.e, because
the requested serial number is not present in the journal, or because
the size of the IXFR response would exceeed "max-ixfr-ratio") are now
logged at level info instead of debug(4).

When dnssec-policy is used, and the zone is not dynamic, BIND will
assume that the zone is inline-signed. But the function responsible
for this did not inherit the dnssec-policy option from the view or
options level, and thus never enabled inline-signing, while the zone
should have been.
This is fixed by this commit.

When dnssec-policy is used, and the zone is not dynamic, BIND will
assume that the zone is inline-signed. Add test cases to verify this.

Fix a comment, ensuring the right parameters are used (zone is
parameter $3, not $2) and add view and policy parameters to the comment.
Fix the view tests and test the correct view (example3 instead of
example2).
Fix placement of "n=$((n+1)" for two test cases.

Before this change the TLS code would ignore the accept callback result,
and would not try to gracefully close the connection. This had not been
noticed, as it is not really required for DoH. Now the code tries to
shut down the TLS connection gracefully when accepting it is not
successful.
(cherry picked from commit ffcb54211e)
This commit removes an assertion from the unit test which cannot be
guaranteed.
According to the test, exactly one client send must succeed. However,
it cannot really be guaranteed, as do not start to read data in the
accept callback on the server nor attach to the accepted handle. Thus,
we can expect the connection to be closed soon after we have returned
from the callback.
Interestingly enough, the test would pass just fine on TCP because:
a) there are fewer layers involved and thus there is less processing;
b) it is possible for the data to be sent and end up in an internal OS
socket buffer without being touched by an application's code on the
server. In such a case the client's write callback still would be
called successfully;
There is a chance for the test to succeed over TLS as well (as it
happily did before), but as the code has been changed to close unused
connections as soon as possible, the chance is far slimmer now.
What can be guaranteed is:
* cconnects == 1 (number client connections equals 1);
* saccepts == 1 (number of accepted connections equals 1).

Otherwise the code path will lead to a call to SSL_get_error()
returning SSL_ERROR_SSL, which in turn might lead to closing
connection to early in an unexpected way, as it is clearly not what is
intended.
The issue was found when working on loppmgr branch and appears to
be timing related as well. Might be responsible for some unexpected
transmission failures e.g. on zone transfers.

In some operations - most prominently when establishing connection -
it might be beneficial to bail out earlier when the network manager
is stopping.
The issue is backported from loopmgr branch, where such a change is
not only beneficial, but required.

In some cases - in particular, in case of errors, NULL might be passed
to a connection callback instead of a handle that could have led to
an abort. This commit ensures that such a situation will not occur.
The issue was found when working on the loopmgr branch.
(cherry picked from commit ac4fb34f18)
This commit ensures that the underlying TCP socket of a TLS connection
gets closed earlier whenever there are no pending operations on it.
In the loop-manager branch, in some circumstances the connection
could have remained opened for far too long for no reason. This
commit ensures that will not happen.
(cherry picked from commit 88524e26ec)
This commit adds a proper implementation of
isc_nmhandle_setwritetimeout() for TLS connections. Now it passes the
value to the underlying TCP handle.

* make it harder to get the interface numbers wrong by using 'max'
to specify the upper bound of the sequence of interfaces and use 'max'
when calculating the interface number
* extract the platform specific instruction into 'up' and 'down'
and call them from the inner loop so that the interface number is
calculated in one place.
* calculate the A and AAAA address in a single place rather than
in each command
* use /sbin/ipadm on Solaris 2.11 and greater

previously, when an iterative query returned FORMERR, resolution
would be stopped under the assumption that other servers for
the same domain would likely have the same capabilities. this
assumption is not correct; some domains have been reported for
which some but not all servers will return FORMERR to a given
query; retrying allows recursion to succeed.

We are grafting on an unsigned zone "example.internal" where the higher
zone (".") is signed and would otherwise cause named to synthesise a
NXDOMAIN for example.internal. We prime the cache by performing a
lookup for "internal" and then lookup "example.internal".

We do this by adding callbacks for when a node is added or deleted
from the keytable. dns_keytable_add and dns_keytable_delete where
extended to take a callback. dns_keytable_deletekey does not remove
the node so it was not extended.

When a zone is attached or detached from the view (zone->view is

Call dns_view_sfd_find to find the namespace to be used to verify
the covering NSEC records returned for the given QNAME. Check that
the NSEC owner names are within that namespace.
(cherry picked from commit 228dadb026)
When namespace is grafted on, the DNSSEC proofs for non existance
need to come from that namespace and not a higher namespace. We
add 3 function dns_view_sfd_add, dns_view_sfd_del and dns_view_sfd_find
to add, remove and find the namespace that should be used when
checking NSEC records.
dns_view_sfd_add adds a name to a tree, creating the tree if needed.
If the name already existed in the tree the reference count is
increased otherwise it is initalised to 1.
dns_view_sfd_del removes a reference to a name in the tree, if the
count goes to 0 the node is removed.
dns_view_sfd_find returns the namespace to be used to entered name.
If there isn't an enclosing name in the tree, or the tree does not
yet exist, the root name is returned.
Access to the tree is controlled by a read/write lock.

The original sscanf processing allowed for a number of syntax errors
to be accepted. This included missing the closing brace in
${modifiers}
Look for both comma and right brace as intermediate seperators as
well as consuming the final right brace in the sscanf processing
for ${modifiers}. Check when we got right brace to determine if
the sscanf consumed more input than expected and if so behave as
if it had stopped at the first right brace.
