<description>This update for mosquitto fixes the following issues:
|
||||
|
||||
Changes in mosquitto:
|
||||
|
||||
- update to 2.0.23 (boo#1258671)
|
||||
* Fix handling of disconnected sessions for `per_listener_settings
|
||||
true`
|
||||
* Check return values of openssl *_get_ex_data() and
|
||||
*_set_ex_data() to prevent possible crash. This could occur only
|
||||
in extremely unlikely situations
|
||||
* Check return value of openssl ASN1_string_[get0_]data()
|
||||
functions for NULL. This prevents a crash in case of incorrect
|
||||
certificate handling in openssl
|
||||
* Fix potential crash on startup if a malicious/corrupt
|
||||
persistence file from mosquitto 1.5 or earlier is loaded
|
||||
* Limit auto_id_prefix to 50 characters
|
||||
|
||||
- Update to version 2.0.22
|
||||
Broker
|
||||
* Bridge: Fix idle_timeout never occurring for lazy bridges.
|
||||
* Fix case where max_queued_messages = 0 was not treated as
|
||||
unlimited.
|
||||
* Fix --version exit code and output.
|
||||
* Fix crash on receiving a $CONTROL message over a bridge, if
|
||||
per_listener_settings is set true and the bridge is carrying
|
||||
out topic remapping.
|
||||
* Fix incorrect reference clock being selected on startup on
|
||||
Linux. Closes #3238.
|
||||
* Fix reporting of client disconnections being incorrectly
|
||||
attributed to "out of memory".
|
||||
* Fix compilation when using WITH_OLD_KEEPALIVE.
|
||||
* Fix problems with secure websockets.
|
||||
* Fix crash on exit when using WITH_EPOLL=no.
|
||||
* Fix clients being incorrectly expired when they have
|
||||
keepalive == max_keepalive. Closes #3226, #3286.
|
||||
Dynamic security plugin
|
||||
* Fix mismatch memory free when saving config which caused
|
||||
memory tracking to be incorrect.
|
||||
Client library
|
||||
* Fix C++ symbols being removed when compiled with link time
|
||||
optimisation.
|
||||
* TLS error handling was incorrectly setting a protocol error
|
||||
for non-TLS errors. This would cause the mosquitto_loop_start()
|
||||
thread to exit if no broker was available on the first
|
||||
connection attempt. This has been fixed. Closes #3258.
|
||||
* Fix linker errors on some architectures using cmake.
|
||||
|
||||
- Update to version 2.0.21
|
||||
Broker
|
||||
* Fix clients sending a RESERVED packet not being quickly
|
||||
disconnected.
|
||||
* Fix bind_interface producing an error when used with an
|
||||
interface that has an IPv6 link-local address and no other
|
||||
IPv6 addresses.
|
||||
* Fix mismatched wrapped/unwrapped memory alloc/free in
|
||||
properties.
|
||||
* Fix allow_anonymous false not being applied in local only mode.
|
||||
* Add retain_expiry_interval option to fix expired retained
|
||||
message not being removed from memory if they are not
|
||||
subscribed to.
|
||||
* Produce an error if invalid combinations of
|
||||
cafile/capath/certfile/keyfile are used.
|
||||
* Backport keepalive checking from develop to fix problems in
|
||||
current implementation.
|
||||
Client library
|
||||
* Fix potential deadlock in mosquitto_sub if -W is used.
|
||||
Apps
|
||||
* mosquitto_ctrl dynsec now also allows -i to specify a clientid
|
||||
as well as -c. This matches the documentation which states -i.
|
||||
Tests
|
||||
* Fix 08-ssl-connect-cert-auth-expired and
|
||||
08-ssl-connect-cert-auth-revoked tests when under load.
|
||||
|
||||
- systemd service: Wait till the network got setup to avoid
|
||||
startup failure.
