2326. [bug] razvan
Fixed a bug which was causing the allocation engine to reject the
lease if a data race caused by a different server updating the
shared database entries was detected. The entire packet is now
dropped in this particular case. This applies to both kea-dhp4
and kea-dhcp6 servers.
(Gitlab #3648)
2325. [bug] razvan
Fixed a bug which was causing address allocation counters to be
negative when client released leases and the server has lease
affinity and lease reclamation enabled.
(Gitlab #1336)
2324. [func] razvan
It is not necessary to restart the server to apply changes in the
TLS configuration. Running the "config-reload" command is
sufficient. A different address or port must be specified when
switching from HTTP to HTTPS or from HTTPS to HTTP.
(Gitlab #3694)
Kea 2.7.6 (development) released on January 29, 2025
2323. [func]* fdupont
Kea now refuses secrets and passwords taken from examples,
including when not built with unit tests "keatest".
(Gitlab #3398)
2322. [bug] marcin
Avoid conflicts in DNS cleanup performed by two servers in
the terminated state in HA.
(Gitlab #3649)
2321. [func] tmark
Modified kea-dhcp4 and kea-dhcp6 to support
DDNS behavioral parameters at the pool level.
(Gitlab #3049)
2320. [bug] fdupont
Fixed a bug where the lease in the released state was not read
properly.
(Gitlab #3699)
2319. [build] fdupont, q66
Kea can now build with Boost 1.87. The minimum supported Boost
version has been bumped up from 1.57 to 1.66. Thanks to q66
for the patch.
(Gitlab #3696)
2318. [build] razvan
The library version numbers have been bumped up for the Kea 2.7.6
development release.
(Gitlab #3724)
2317. [bug] razvan
Fixed a bug related to database connection recovery which was
preventing the server to resume processing packets because the
dhcp state was never re-enabled.
(Gitlab #3727)
2316. [func] razvan
The kea-dhcp4, kea-dhcp6 and kea-dhcp-ddns servers now support
multiple http/https connections. The can be configured in the
"control-sockets" list.
(Gitlab #3082, #3721)
2315. [func] razvan
Kea can now load hook libraries specifying only the binary name.
It uses the default hook libraries installation path which is
provided in the config report as "Hooks directory".
(Gitlab #2101, #3579)
2314. [func] tmark
Added three new parameters which may be used to
influence DNS TTL to kea-dhcp4 and kea-dhcp6:
'ddns-ttl', 'ddns-ttl-min', and 'ddns-ttl-max'.
(Gitlab #2819, #3663)
Kea 2.7.5 (development) released on December 11, 2024
2313. [doc] marcin
Clarified that the FLQ allocator should not be used with shared
lease database.
(Gitlab #3577)
2312. [doc] fdupont
Made clear that when a HTTP control channel is reconfigured
with the same address and port the listener socket is reused
so any TLS setup change is ignored.
(Gitlab #3255)
2311. [doc] piotrek
Added a more extensive definition of the tuple DHCP option
type in the ARM documentation.
(Gitlab #3661)
2310. [bug] andrei
Kea servers no longer increase in memory when being reconfigured.
(Gitlab #3652)
2309. [build] mgodzina
The library version numbers have been bumped up for the Kea 2.7.5
development release.
(Gitlab #3695)
2308. [bug] marcin
Prevent the servers from returning to HA maintenance
states after receiving the ha-maintenance-cancel command
while they also respond to the DHCP traffic.
(Gitlab #3655)
2307. [func] tmark
The parameter "client-class" (a single class name) in
shared networks, subnets, and pools has been replaced with
"client-classes" (a list of one or more class names).
This applies to both kea-dhcp4 and kea-dhcp6.
(Gitlab #3592)
2306. [func] fdupont
Added a new "http-headers" parameter to the CA and
HTTP control socket configuration sections which can
be used to specify extra 'name: value' headers to be
added to HTTP responses.
(Gitlab #3609)
2305. [func] tmark
Both kea-dhcp4 and kea-dhcp6 servers will now
log a warning message when they detect classes that
configure lease life time parameters (e.g. 'valid-lifetime',
'preferred-lifetime') while also setting
'only-in-additional-list' to true.
(Gitlab #2736)
2304. [bug] tmark
Modified both kea-dhcp4 and kea-dhcp6 to avoid
generating DDNS update requests when leases are
being reused due to lease caching.
(Gitlab #3257)
Kea 2.7.4 (development) released on October 30, 2024
2303. [func] tmark
The parameters 'require-client-classes' and
'only-if-required' have been replaced with 'evaluate-
additional-classes' and 'only-in-additional-list'
respectively and deprecated. This applies to both
kea-dhcp4 and kea-dhcp6.
(Gitlab #3587)
2302. [func] tmark
Options may now be configured with a list of client
classes for which they apply. This feature is referred to
as "option class-tagging" and is supported by both
kea-dhcp4 and kea-dhcp6.
(GitLab #3583)
2301. [func] fdupont
Added support of DHCPv4 "cablelab-client-conf" (122) option
and its associated suboptions specified by RFC 3495, 3594
and 3634 in the "cablelabs-client-conf" space at the
exception of the suboption 3.
(Gitlab #3404)
2300. [build, func] andrei
Standalone fuzz target binaries used in fuzz testing were added
to the "fuzz" directory.
(Gitlab #3605)
2299. [func]* fdupont
Required classes are now evaluated in the same order as
for option data, i.e. (pd-)pool, subnet and shared network.
Before the order was reversed but this feature was not
used.
(Gitlab #3590)
2298. [bug] fdupont
Fixed a bug where Kea did not return the value of
vendor-encapsulated-options when redefined in a client class.
(Gitlab #3582)
2297. [build]* fdupont
Made the Botan boost TLS support mandatory. Changed
the configure argument to --with-botan using
the Botan pkg-config library name e.g. "botan-2".
(Gitlab #3552)
2296. [func]* fdupont
Classes included in 'require-client-classes' that do
not have test expressions will now be unconditionally
added to the client's list of matching classes.
Previously they were ignored.
(Gitlab #3388)
2295. [func] fdupont
Relaxed the lease, host and config database backend types
in the configuration syntax. This change is introduced to
better handle optional backends provided in hooks, such as
currently available MySQL or PostgreSQL hooks.
(Gitlab #3585)
2294. [func] fdupont
Added support of DHCPv6 "ntp-server" (56) option
specified by RFC 5908 and its associated suboptions
in the "v6-ntp-server-suboptions" space.
(Gitlab #3390)
2293. [build] razvan

The events that logged EVAL_RESULT now log a different message

kea-netconf recovers instead of crashing. These scenarios are
corner cases that are likely not found in production and that

High Availability hook now supports lease affinity for the
released leases. When a lease is released but left in the
database for a possible re-allocation this information is
propagated to the partner server. Previously, a released
lease was always deleted in the partner, causing a loss of
the association between the lease and the client in the
partner's lease database. This change introduces a new
"released" lease state which appears for the released leases
in the lease database and in the lease updates exchanged
between the HA partners. It is a backward incompatible change
for the HA partners that haven't been upgraded to the latest
Kea version. They will reject the lease updates for the
released leases holding the new state value.
