Many already supported RFCs are now listed in the Supported
DHCP standards and Supported DHCPv6 standards in the Kea
Administrator Reference Manual (ARM).
(Gitlab #3346)

"hostname-char-set".
(Gitlab #2958)
2237. [doc] slawek
Added an instruction to the ARM on how to verify the PGP
signature of the tarball with the source code.
(Gitlab #3021)
2236. [doc] marcin

RADIUS with the hub-and-spoke configurations in HA.
(Gitlab #3252)
2235. [bug] tmark
Remove defaulted on-update behavior from 'expire'
columns in lease4 and lease6 tables for MySQL/Mariadb
lease databases. Corrects an issue when upgrading from
releases prior to Kea 2.4.0 to Kea 2.4.0 or later with
Mariadb version 10.10 or later that causes all existing
v6 leases to expire immediately.
(Gitlab #3396)
2234. [build] andrei
Kea now builds with MySQL client libraries that have removed the
mysql_ssl_set function which was deprecated in MySQL 8.0.35.
The mysql_options function is used instead.
(Gitlab #3256)
2233. [bug] razvan
Fixed a bug which was causing the status-get command to return
an error when the lease database connection had not yet been
established.
(Gitlab #3223)
2232. [func]* fdupont
Auto-generated subnet identifiers are no longer supported.
Configurations that contain subnets without explicit subnet
identifiers (i.e. without an "id" entry) will now be rejected.
(Gitlab #2961)
2231. [func] fdupont
The "ip-address" configuration parameter in the "relay" map has
been removed. In its place, use "ip-addresses" introduced in
Kea 1.4.
(Gitlab #3378)
2230. [func] tmark
Both kea-dhcp4 and kea-dhcp6 will now emit an INFO
level log statement for each packet received and
sent by the server. Formerly these logs were only
emitted at DEBUG level.
(Gitlab #3203)
2229. [bug] tmark
Kea now builds with MySQL client libraries that have removed the
the MYSQL_OPT_RECONNECT feature and, in those cases, no longer
explicitly disables the reconnect feature, but relies on its
default disabled state.
(Gitlab #3311)
Kea 2.5.8 (development) released on April 30, 2024
2228. [build] piotrek
The library version numbers have been bumped up for the Kea 2.5.8
development release.
(Gitlab #3355)
2227. [func] fdupont
Implemented the stash-agent-options global parameter
for DHCPv4 (new feature from ISC DHCP allowing to
renew reserved address when the host reservation identifier
is based on the dhcp-agent-options option added by a relay.
(Gitlab #2976)
2226. [func] piotrek
Added information about transaction ID in all possible
places in loggers: alloc-engine, bad-packets, ddns,
eval, leases, options, packets.
(Gitlab #2820)
2225. [func] marcin
Ensure backward compatibility of High Availability
between Kea 2.5.8+ and earlier versions. It introduces
a new origin-id argument to the dhcp-enable, dhcp-disable
and ha-sync-complete-notify commands. It is ignored by the
earlier Kea versions. The origin argument is sent in addition
to the origin-id and has the format recognizable by the old
Kea versions.
(Gitlab #3344)
2224. [func] andrei
Printing the version now mentions if premium is included and
shows the git commit hash for the premium source code repository
if the executable is built from sources.
(Gitlab #3254)
2223. [bug] tmark
Fixed an issue in PerfMon hook library which causes
the kea6_server to crash when the server responds
to a client query for which no subnet was selected.
(Gitlab #3347)
2222. [bug] piotrek
Fixed a bug in host_cmds. When PostgreSQL was used as
hosts database storage, reservation-del command called
with given IPv6 host address and the subnet Id deleted
all IPv6 hosts in given subnet.
Corrected the issue so that now only given host
reservation is deleted.
(Gitlab #3294)
2221. [bug] tmark
Corrected an index on the dhcp4_servers table
in the PostgreSQL schema.
(Gitlab #2957)
2220. [bug] marcin
Exclude packets ignored during load balancing from the
pkt6-receive-drop statistics. The packets dropped by the
HA hook library during subnet selection are counted in
the pkt4-receive-drop and pkt6-receive-drop statistics.
(Gitlab #3125)
2219. [bug] marcin
Corrected an issue in processing the server-name argument
of the ha-sync command. The argument was ignored when the
synchronization with a backup server was performed.
(Gitlab #3276)
2218. [func] marcin
Addressed an inconsistent state of the High Availability
service that occurs when one of the terminated services is
restarted and another one is not. The restarted service waits 10
minutes for the partner restart. If the partner is not restarted
the service transitions to the terminated state to continue
responding to the DHCP traffic.
(Gitlab #3250)
2217. [func] fdupont
Extended the lenient-option-parsing compatibility
flag to ignore DHCPv4 fqdn (81) and DHCPv6 client-fqdn
(39) options with some invalid domain names (e.g.
beginning with an empty label).
(Gitlab #3289)
2216. [func] tmark

2183. [bug] andrei
Fixed a bug where one of the commands that retrieve statistic
values sent to the kea-ctrl-agent would get an overflow error in
the response if the inquired statistic was intended to have a big
integer data type, and if the integer value would not be
representable on 64 bits. Affected statistics are "total-nas" and
"total-pds", and the bug only manifests if the inquired pool, or
the inquired subnet's aggregated pool space, is large enough.
Prior to this fix, commands would get a correct response over
unix socket.

Implemented Free Lease Queue allocator. It can be used for
address assignment in DHCPv4 and prefix delegation in DHCPv6.
The allocator is suitable when the DHCP servers work with
nearly depleted pools, and the time to find an available
lease becomes long with other allocators. The new allocator,
however, slows down the server startup and reconfiguration.
It also uses more memory.

Fixed a bug which was changing the multi-threading settings when
running config-test command and the settings were different from
the server's configuration. This also fixes the rollback on the
multi-threading settings if there is a configuration error
detected. Also hooks now set DROP flag on the
dhcp4_srv_configured and dhcp6_srv_configured callouts if the
configuration is invalid or an error occured. Proper shutdown
of the HTTP listener is performed now instead of generating a
server crash if the provided address is not valid.

2113. [bug] razvan
The reload functionality (by sending SIGHUP) of the kea-dhcp4

default for the core Kea DHCP service ("enable-multi-threading"
set to true). For now, HA+MT is still disabled by default
("enable-multi-threading" and "http-dedicated-listener" both
still set to false in the high-availability library parameters).

The logger to which kea-dhcp4 now logs EVAL_RESULT log
messages issued during packet classification has been
changed from "options4" to "dhcp4". This corrects an
inconsistency between kea-dhcp6 and kea-dhcp4 behavior.

Shell tests and python tests no longer run if gtest is disabled.
This provides the ability to run distcheck without tests.

An address reserved in a global reservation must now lie
within the range of the subnet or shared-network selected
by Kea. If it does not, the server will attempt to allocate an
address dynamically. This change applies to both kea-dhcp4 and
kea-dhcp6. Previously, the servers would grant a lease for any
globally reserved address without regard for its feasibility
within the selected subnet. Thanks to Kyle Birkeland for
reporting the issue and contributing the patch.

Updated client classification examples in the ARM with a case
where both operands of the evaluated expression are computed at
runtime.
