[ANNOUNCE] Apache PLC4X 0.12.0 released
The Apache PLC4X team is pleased to announce the release of Apache PLC4X 0.12.0 PLC4X is a set of libraries for communicating with industrial programmable logic controllers (PLCs) using a variety of protocols but with a shared API. This release was mainly a release containing many bugfixes. We literally halved the number of open issues. A second major topic would have been another API streamlining in preparation for the big 1.0.0 release. The API was extended by additional features, that now allow tools to automatically provide support for tool assist when connecting to devices. Now additional information such as: - Which transports does a given driver support? - Which is the default transport for a given driver? - Which configuration-options does a driver have? - What types are these configuration options? - What are the default-values these configuration options have? - Which of these configuration options are required? - The same set of information is also available for the transports a driver is using. Especially the S7, Modbus and OPC-UA drivers received the most bugfixes and improvements. S7 now supports all supported S7 datatypes. Modbus should now also work in Serial modes. OPC-UA now supports certificate based communication. Visit the Apache PLC4X website [1] for general information or the downloads page [2] for release notes and download information.

[ANNOUNCE] Apache PLC4X 0.10.0 released
The Apache PLC4X team is pleased to announce the release of Apache PLC4X 0.11.0 PLC4X is a set of libraries for communicating with industrial programmable logic controllers (PLCs) using a variety of protocols but with a shared API. A lot of the work in this version went into refactoring and cleaning up our code generation. The code generation itself is now a lot cleaner and simpler as well as the code generated for Java. We also added a number of new field-types to allow implementing more sophisticated protocols. PLC4C now should also support all of the constructs mspec has to offer. New Features - Implemented a `PLC4X-Server` and `PLC4X-Driver` that allows using the server as a proxy for communicating with PLCs. - The Modbus driver is now also available in the variants: "modbus-rtu" and "modbus-ascii" (Both using Serial communication, which however can be tunneled through a "tcp" and "udp" transport) - The KNX driver in Java now supports reading "knxproj" files exported from the new ETS version 6. Incompatible changes - The name of the Modbus TCP driver was changed from "modbus" to "modbus-tcp". - Removed the Apache Edgent (incubating) integration and examples related, as Edgent is abandoned and there were CVEs reported, which will not be fixed. - We have replaced the BitString types with BYTE, WORD, DWORD, and LWORD which generally match their unsigned integer counterparts. So we are no longer returning lists of boolean values for any of these types.

CVE-2021-43083: Apache PLC4X 0.9.0 Buffer overflow in PLC4C via crafted server response
Description: Apache PLC4X - PLC4C (Only the C language implementation was effected) was vulnerable to an unsigned integer underflow flaw inside the tcp transport. Users should update to 0.9.1, which addresses this issue. However, in order to exploit this vulnerability, a user would have to actively connect to a mallicious device which could send a response with invalid content. Currently we consider the probability of this being exploited as quite minimal, however this could change in the future, especially with the industrial networks growing more and more together. Credit: Apache PLC4X would like to thank Eugene Lim for reporting this issue. References: https://lists.apache.org/thread/jxx6qc84z60xbbhn6vp2s5qf09psrtc7

We also took the opportunity to fix some of the problems we noticed on the old drivers. Please note that starting with this version the connection string syntax has changed significantly and for some drivers also the address syntax. So please be sure to double check our driver documentation here: https://plc4x.apache.org/users/protocols/index.html However we suggest to update with caution and not instantly go into production without previously testing. As with all new things, even if we did a serious amount of testing, there might be issues hidden in the details. If you should find any regression issues, please report them as we are planning on speeding up the release- train significantly with this release. For the time being the 0.6.0 branch will continue to be maintained until feedback from the community makes us feel safe with focusing solely on the new drivers. Regards, The Apache PLC4X team

New Apache mailing-list for inter-project communication with a focus on IoT related topics
There's a lot of magic happening in the IoT sector at the moment. A lot of new projects are appearing and older projects are growing and extending their functionality. We have noticed that it's currently quite difficult to keep track who the players in this field are and what they're up to. So we decided to create a new mailing-list to help improve the communication: i...@apache.org (Archive at: https://lists.apache.org/list.html?i...@apache.org) We hope this communication-channel will help reduce unnecessary double-work and improve streamlining the projects to work together as good a possible. So if you're involved in projects in the IoT sector, if you want to be involved and haven't found the right project to contribute yet, or if you just want to know what's up, it would be great to see you on this list (Subscribe by sending an email to: iot-subscr...@apache.org) Corresponding Blog-Post: https://blogs.apache.org/comdev/entry/new-apache-mailing-list-for Chris

[ANNOUNCE] Apache Flex BlazeDS 4.7.3
Hi all,
I am pleased to announce the release of Apache Flex BlazeDS 4.7.3.
Apache Flex BlazeDS 4.7.3 is an update to 4.7.2 which adds a new
blazeds-spring-boot-starter module for easily setting up a BlazeDS server with
Spring Boot.
It also provides Maven archetypes for easily creating new spring-boot project
that
make use of BlazeDS.
We also did quite a lot of fine-tuning of the security default settings to make
BlazeDS
more secure.
Starting with 4.7.3 BlazeDS Deserialization of XML is disabled completely per
default
but can easily be enabled in your services-config.xml:
http://{server.name}:{server.port}/{context.root}/messagebroker/amf "
class="flex.messaging.endpoints.AMFEndpoint"/>
true
Also, we now enable the ClassDeserializationValidator per default to only allow
deserialization of whitelisted classes. BlazeDS internally comes with the
following
whitelist:
flex.messaging.io.amf.ASObject
flex.messaging.io.amf.SerializedObject
flex.messaging.io.ArrayCollection
flex.messaging.io.ArrayList
flex.messaging.messages.AcknowledgeMessage
flex.messaging.messages.AcknowledgeMessageExt
flex.messaging.messages.AsyncMessage
flex.messaging.messages.AsyncMessageExt
flex.messaging.messages.CommandMessage
flex.messaging.messages.CommandMessageExt
flex.messaging.messages.ErrorMessage
flex.messaging.messages.HTTPMessage
flex.messaging.messages.RemotingMessage
flex.messaging.messages.SOAPMessage
java.lang.Boolean
java.lang.Byte
java.lang.Character
java.lang.Double
java.lang.Float
java.lang.Integer
java.lang.Long
java.lang.Object
java.lang.Short
java.lang.String
java.util.ArrayList
java.util.Date
java.util.HashMap
org.w3c.dom.Document
If you need to deserialize any other classes, be sure to register them in your
services-config.xml:
(Beware, by manually providing a whitelist the default whitelist is disabled)
Known Issues
_
FLEX-34648 Memory Leak occurred in AsyncMessage when sending a lot of messages
