Please unblock package mosquitto
[ Reason ]
Mosquitto 2.0.8 is currently in testing, Mosquitto 2.0.9 was released on
2021-03-11 and has sufficiently important fixes in it that I believe
should be in a Debian release.
The full debdiff is 1110 lines. If I reduce that to code-only changes it
drops to 387 (the remainder are documentation and extra tests), with
about 150 lines of actual affected code. It is a small bugfix release
with low risk but some reasonably important fixes.
[ Impact ]
I have listed the fixes below that I think are worth mentioning. The
other changes are of minor impact or are fixing strict compiler
warnings.
Client and library: There is a fairly minor security issue that affects
outgoing client connections only - if an empty or corrupt CA certificate
is provided to a client, then the initial connection would fail but
subsequent connections would succeed without verifying the remote server
certificate. There is a new test for this behaviour, but it is not in
the 2.0.9 release.
Build: The CMake build script was not enabling epoll(), so poll() was
being used instead which has a very detrimental impact on performance.
Server: Messages published with QoS 0 were not being delivered when
`max_queued_bytes` was configured. This has a big impact on users
wanting to use QoS 0, which is the most common QoS, but also set some
client limits. There is a new test to check this behaviour.
Server: If the `max_keepalive` option was set, this did not apply to
clients connecting with keepalive set to 0 (which means "infinite keepalive").
This gives a very straightforward means to circumvent the wishes of the
server operator, although in itself it isn't very important.
Server: The behaviour setting acceptable TLS versions did not match the
documentation.
Server: Messages to '$' prefixed MQTT topics were being rejected. This
is not security critical but very annoying for a user wanting to use
that feature.
[ Tests ]
The release introduces a new test that covers one issue. A test
exists for the CA issue but is not part of this release.
[ Risks ]
I believe this to be low risk. Most of the code changes are reasonably
simple.
shairport-sync, kamailio-mqtt-module, and baresip-core depend on
libmosquitto1. The changes to the library code are trivial.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
[ Other info ]
mosquitto_2.0.8-mosquitto-2.0.9.debdiff is the full debdiff.
mosquitto_2.0.8-mosquitto-2.0.9-code.debdiff is the code only debdiff.

+2.0.9 - 2021-03-11
+==================
+
+Security:
+- If an empty or invalid CA file was provided to the client library for
+ verifying the remote broker, then the initial connection would fail but
+ subsequent connections would succeed without verifying the remote broker
+ certificate. Closes #2130.
+- If an empty or invalid CA file was provided to the broker for verifying the
+ remote broker for an outgoing bridge connection then the initial connection
+ would fail but subsequent connections would succeed without verifying the
+ remote broker certificate. Closes #2130.
+
+Broker:
+- Fix encrypted bridge connections incorrectly connecting when `bridge_cafile`
+ is empty or invalid. Closes #2130.
+- Fix `tls_version` behaviour not matching documentation. It was setting the
+ exact TLS version to use, not the minimium TLS version to use. Closes #2110.
+- Fix messages to `$` prefixed topics being rejected. Closes #2111.
+- Fix QoS 0 messages not being delivered when max_queued_bytes was configured.
+ Closes #2123.
+- Fix bridge increasing backoff calculation.
+- Improve handling of invalid combinations of listener address and bind
+ interface configurations. Closes #2081.
+- Fix `max_keepalive` option not applying to clients connecting with keepalive
+ set to 0. Closes #2117.
+
+Client library:
+- Fix encrypted connections incorrectly connecting when the CA file passed to
+ `mosquitto_tls_set()` is empty or invalid. Closes #2130.
+- Fix connections retrying very rapidly in some situations.
+
+Build:
+- Fix cmake epoll detection.
