Fedora 31: mosquitto FEDORA-2019-4c69fb4cd7
Summary
Mosquitto is an open source message broker that implements the MQ Telemetry
Transport protocol version 3.1 and 3.1.1 MQTT provides a lightweight method
of carrying out messaging using a publish/subscribe model. This makes it
suitable for "machine to machine" messaging such as with low power sensors
or mobile devices such as phones, embedded computers or micro-controllers
like the Arduino.
1.6.7 ===== Broker: * Add workaround for working with libwebsockets 3.2.0. *
Fix potential crash when reloading config. Client library: * Don't use / in
autogenerated client ids, to avoid confusing with topics. * Fix
mosquitto_max_inflight_messages_set() and mosquitto_int_option(...,
MOSQ_OPT_*_MAX, ...) behaviour. * Fix regression on use of
mosquitto_connect_async() not working. Clients: * mosquitto_sub: Fix -E
incorrectly not working unless -d was also specified. * Updated documentation
around automatic client ids. 1.6.6 ===== Security: * CVE-2019-11779 *
Restrict topic hierarchy to 200 levels to prevent possible stack overflow.
Broker: * Restrict topic hierarchy to 200 levels to prevent possible stack
overflow. * mosquitto_passwd now returns 1 when attempting to update a user that
does not exist. 1.6.5 ===== Broker: * Fix v5 DISCONNECT packets with
remaining length == 2 being treated as a protocol error. * Fix support for
libwebsockets 3.x. * Fix slow websockets performance when sending large
messages. * Fix bridges potentially not connecting on Windows. * Fix clients
authorised using `use_identity_as_username` or `use_subject_as_username` being
disconnected on SIGHUP. * Improve error messages in some situations when clients
disconnect. Reduces the number of "Socket error on client X, disconnecting"
messages. * Fix Will for v5 clients not being sent if will delay interval was
greater than the session expiry interval. * Fix CRL file not being reloaded on
HUP. * Fix repeated "Error in poll" messages on Windows when only websockets
listeners are defined. Client library: * Fix reconnect backoff for the
situation where connections are dropped rather than refused. * Fix missing locks
on `mosq->state`. Documentation: * Improve details on global/per listener
options in the mosquitto.conf man page. * Clarify behaviour when clients exceed
the `message_size_limit`. * Improve documentation for `max_inflight_bytes`,
`max_inflight_messages`, and `max_queued_messages`.
