|
|
Versions 2.0.15 of Mosquitto has been released. This is a security
|
|
and bugfix release.
|
|
|
|
# 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].
|
|
|
|
