2.0.15 - 2022-08-16
===================
Security:
- Deleting the group configured as the anonymous group in the Dynamic Security
plugin, would leave a dangling pointer that could lead to a single crash.
This is considered a minor issue - only administrative users should have
access to dynsec, the impact on availability is one-off, and there is no
associated loss of data. It is now forbidden to delete the group configured
as the anonymous group.
Broker:
- Fix memory leak when a plugin modifies the topic of a message in
MOSQ_EVT_MESSAGE.
- Fix bridge `restart_timeout` not being honoured.
- Fix potential memory leaks if a plugin modifies the message in the
MOSQ_EVT_MESSAGE event.
- Fix unused flags in CONNECT command being forced to be 0, which is not
required for MQTT v3.1. Closes #2522.
- Improve documentation of `persistent_client_expiration` option.
Closes #2404.
- Add clients to session expiry check list when restarting and reloading from
persistence. Closes #2546.
- Fix bridges not sending failure notification messages to the local broker if
the remote bridge connection fails. Closes #2467. Closes #1488.
- Fix some PUBLISH messages not being counted in $SYS stats. Closes #2448.
- Fix incorrect return code being sent in DISCONNECT when a client session is
taken over. Closes #2607.
- Fix confusing "out of memory" error when a client is kicked in the dynamic
security plugin. Closes #2525.
- Fix confusing error message when dynamic security config file was a
directory. Closes #2520.
- Fix bridge queued messages not being persisted when local_cleansession is
set to false and cleansession is set to true. Closes #2604.
- Dynamic security: Fix modifyClient and modifyGroup commands to not modify
the client/group if a new group/client being added is not valid.
Closes #2598.
- Dynamic security: Fix the plugin being able to be loaded twice. Currently
only a single plugin can interact with a unique $CONTROL topic. Using
multiple instances of the plugin would produce duplicate entries in the
config file. Closes #2601. Closes #2470.
- Fix case where expired messages were causing queued messages not to be
delivered. Closes #2609.
Client library:
- Fix threads library detection on Windows under cmake. Bumps the minimum
cmake version to 3.1, which is still ancient.
- Fix use of `MOSQ_OPT_TLS_ENGINE` being unable to be used due to the openssl
ctx not being initialised until starting to connect. Closes #2537.
- Fix incorrect use of SSL_connect. Closes #2594.
- Don't set SIGPIPE to ignore, use MSG_NOSIGNAL instead. Closes #2564.
- Add documentation of struct mosquitto_message to header. Closes #2561.
- Fix documentation omission around mosquitto_reinitialise. Closes #2489.
- Fix use of MOSQ_OPT_SSL_CTX when used in conjunction with
MOSQ_OPT_SSL_CTX_DEFAULTS. Closes #2463.
- Fix failure to close thread in some situations. Closes #2545.
Clients:
- Fix mosquitto_pub incorrectly reusing topic aliases when reconnecting.
Closes #2494.
Apps:
- Fix `-o` not working in `mosquitto_ctrl`, and typo in related documentation.
Closes #2471.
2.0.14 - 2021-11-17
===================
@ -25,6 +91,9 @@ Broker:
- Fix broker sending duplicate CONNACK on failed MQTT v5 reauthentication.
Closes #2339.
- Fix mosquitto_plugin.h not including mosquitto_broker.h. Closes #2350.
- Fix unlimited message quota not being properly checked for incoming
messages. Closes #2593.
- Fixed build for openssl compiled with OPENSSL_NO_ENGINE. Closes #2589.
Client library:
- Initialise sockpairR/W to invalid in `mosquitto_reinitialise()` to avoid

Versions 2.0.15 of Mosquitto has been released. This is a security

plugin, would leave a dangling pointer that could lead to a single crash.
This is considered a minor issue - only administrative users should have
access to dynsec, the impact on availability is one-off, and there is no
associated loss of data. It is now forbidden to delete the group configured
as the anonymous group.
# Broker
- Fix memory leak when a plugin modifies the topic of a message in
`MOSQ_EVT_MESSAGE`.
- Fix bridge `restart_timeout` not being honoured.
- Fix potential memory leaks if a plugin modifies the message in the
`MOSQ_EVT_MESSAGE` event.
- Fix unused flags in CONNECT command being forced to be 0, which is not
required for MQTT v3.1. Closes [#2522].
- Improve documentation of `persistent_client_expiration` option.
Closes [#2404].
- Add clients to session expiry check list when restarting and reloading from
persistence. Closes [#2546].
- Fix bridges not sending failure notification messages to the local broker if
the remote bridge connection fails. Closes [#2467]. Closes [#1488].
- Fix some PUBLISH messages not being counted in $SYS stats. Closes [#2448].
- Fix incorrect return code being sent in DISCONNECT when a client session is
taken over. Closes [#2607].
- Fix confusing "out of memory" error when a client is kicked in the dynamic
security plugin. Closes [#2525].
- Fix confusing error message when dynamic security config file was a
directory. Closes [#2520].
- Fix bridge queued messages not being persisted when local_cleansession is
set to false and cleansession is set to true. Closes [#2604].
- Dynamic security: Fix modifyClient and modifyGroup commands to not modify
the client/group if a new group/client being added is not valid.
Closes [#2598].
- Dynamic security: Fix the plugin being able to be loaded twice. Currently
only a single plugin can interact with a unique $CONTROL topic. Using
multiple instances of the plugin would produce duplicate entries in the
config file. Closes [#2601]. Closes [#2470].
- Fix case where expired messages were causing queued messages not to be
delivered. Closes [#2609].
# Client library
- Fix threads library detection on Windows under cmake. Bumps the minimum
cmake version to 3.1, which is still ancient.
- Fix use of `MOSQ_OPT_TLS_ENGINE` being unable to be used due to the openssl
ctx not being initialised until starting to connect. Closes [#2537].
- Fix incorrect use of SSL_connect. Closes [#2594].
- Don't set SIGPIPE to ignore, use MSG_NOSIGNAL instead. Closes [#2564].
- Add documentation of struct mosquitto_message to header. Closes [#2561].
- Fix documentation omission around mosquitto_reinitialise. Closes [#2489].
- Fix use of MOSQ_OPT_SSL_CTX when used in conjunction with
MOSQ_OPT_SSL_CTX_DEFAULTS. Closes [#2463].
- Fix failure to close thread in some situations. Closes [#2545].
# Clients
- Fix mosquitto_pub incorrectly reusing topic aliases when reconnecting.
Closes [#2494].
# Apps
- Fix `-o` not working in `mosquitto_ctrl`, and typo in related documentation.
Closes [#2471].
