574. [func] tmark
577. [func] muks
Added an SQLite3 index on records(rname, rdtype). This decreases
insert performance by ~28% and adds about ~20% to the file size,
but increases zone iteration performance. As it introduces a new
index, a database upgrade would be required.
(Trac #1756, git 9b3c959af13111af1fa248c5010aa33ee7e307ee)
576. [bug] tmark, tomek
b10-dhcp6: Fixed bug when the server aborts operation when
receiving renew and there are no IPv6 subnets configured.
(Trac 2719, git 3132b8b19495470bbfd0f2ba0fe7da443926034b)
575. [bug] marcin
b10-dhcp6: Fixed the bug whereby the subnet for the incoming
packet was selected using only its source address. The subnet
is now selected using either source address or the name of the
server's interface on which the packet has been received.
(Trac #2704, git 1cbacf19a28bdae50bb9bd3767bca0147fde37ed)
574. [func] tmark
b10-dhcp4, b10-dhcp6: Composite key indexes were added to the lease
tables to reduce lease search time. The lease4 table now has two
additional indexes: a) hwaddr/subnet_id and b) client_id/subnet_id.
The lease6 now has the one additional index: iaid/subnet_id/duid.
Adding these indexes significantly improves lease acquisition
performance.

During startup the IPv6 DHCP server failed to detect any network
interfaces and is therefore shutting down.
% DHCP6_NO_SUBNET_DEF_OPT failed to find subnet for address %1 when adding default options
This warning message indicates that when attempting to add default options
to a response, the server found that it was not configured to support
the subnet from which the DHCPv6 request was received. The packet has
been ignored.
% DHCP6_NO_SUBNET_REQ_OPT failed to find subnet for address %1 when adding requested options
This warning message indicates that when attempting to add requested
options to a response, the server found that it was not configured
to support the subnet from which the DHCPv6 request was received.
The packet has been ignored.

% DHCP6_QUERY_DATA received packet length %1, data length %2, data is %3
A debug message listing the data received from the client or relay.
% DHCP6_RENEW_UNKNOWN_SUBNET RENEW message received from client on unknown subnet (duid=%1, iaid=%2)
A warning message indicating that a client is attempting to renew his lease,
but the server does not have any information about the subnet this client belongs
to. This may mean that faulty the mobile client changed its location and is trying to
renew its old address (client is supposed to send confirm, not rewew in such cases,
according to RFC3315) or the server configuration has changed and information about
existing subnet was removed. Note that in a sense this is worse case of DHCP6_UNKNOWN_RENEW,
as not only the lease is unknown, but also the subnet is. Depending on the reasons
of this condition, it may or may not correct on its own.
% DHCP6_REQUIRED_OPTIONS_CHECK_FAIL %1 message received from %2 failed the following check: %3
This message indicates that received DHCPv6 packet is invalid. This may be due
to a number of reasons, e.g. the mandatory client-id option is missing,
