This document discusses how to write shared libraries. It begins with a brief history of shared libraries for Linux, noting the limitations of the original a.out format. It then summarizes some of the drawbacks of the a.out approach for shared libraries, before introducing ELF (Executable and Linkable Format) as an improved standard. The document stresses that while ELF removes many restrictions, there are still rules that must be followed to generate decent code from shared libraries and additional techniques required for optimized code.
The document introduces Open Virtual Platforms (OVP) as a solution for developing embedded software for multicore systems on chips (SoCs). OVP provides an open way to model virtual platforms using instruction-accurate software models that can run embedded software quickly for testing and development. It consists of APIs for modeling processors, peripherals and complete platforms, an open source library of models, and a reference simulator. OVP aims to establish common open standards for software virtual platforms.
This document introduces Open Virtual Platforms (OVP) and discusses the growing challenges of embedded software development. It notes that embedded software costs are rising dramatically and now exceed hardware costs for system-on-chip designs. It also describes how the number of processor cores in chips is increasing significantly. This makes embedded software development for multicore systems an extreme challenge. The document argues that virtual platforms can help address this challenge by allowing software testing and development to begin earlier in the design cycle before actual hardware is available. It outlines a four phase process moving towards better programming paradigms and tools for parallel programming and multicore platforms, with virtual platforms playing a key role.

Developing Safety-Critical Java Applications with oSCJ Aleš Plšek
We present oSCJ, an implementation of the draft of Safety Critical Java (SCJ) specification. SCJ is designed to make Java amenable to writing mission- and safety-critical soft- ware. It does this by defining a subset of the Real-time Specification for Java that trades expressiveness for verifia- bility. This paper gives a high-level description of our im- plementation of the first compliance level of the SCJ speci- fication, a library called oSCJ, and reports on performance evaluation on the Ovm real-time Java virtual machine. We compare SCJ to C on both a real-time operating system on the LEON3 platform and Linux on a x86. Our results suggest that a high-degree of predictability and competitive performance can indeed be achieved.

A protocol analysis session can capture several types of Ethernet errors including local collisions, remote collisions, late collisions, CRC/alignment errors, long and short packets, and jabber. Local collisions occur on the local segment and are considered normal up to 1% of overall traffic. Remote collisions indicate a problem on another segment. Late collisions mean a collision occurred after 64 bytes were transmitted, possibly due to a NIC that cannot hear properly. CRC/alignment errors above 2-3% of traffic suggest a problem with packet transmission. Long or short packets are outside the normal 64-512 byte frame size and may be caused by a failing NIC. Jabber occurs when a NIC continuously transmits garbled bits for over 1,518

The DevOps paradigm - the evolution of IT professionals and opensource toolkitMarco Ferrigno
This document discusses the DevOps paradigm and tools. It begins by defining DevOps as focusing on communication and cooperation between development and operations teams. It then discusses concepts like continuous integration, delivery and deployment. It provides examples of tools used in DevOps like Docker, Kubernetes, Ansible, and monitoring tools. It discusses how infrastructure has evolved to be defined through code. Finally, it discusses challenges of security in DevOps and how DevOps works aligns with open source principles like meritocracy, metrics, and continuous improvement.
This document summarizes the DevOps paradigm and tools. It discusses how DevOps aims to improve communication and cooperation between development and operations teams through practices like continuous integration, delivery, and deployment. It then provides an overview of common DevOps tools for containers, cluster management, automation, CI/CD, monitoring, and infrastructure as code. Specific tools mentioned include Docker, Kubernetes, Ansible, Jenkins, and AWS CloudFormation. The document argues that adopting open source principles and emphasizing leadership, culture change, and talent growth are important for successful DevOps implementation.
Using Docker container technology with F5 Networks products and servicesF5 Networks
This document discusses how Docker containerization technology can be used with F5 products and services. It provides an overview of Docker, comparing it to virtual machines. Docker allows for higher resource utilization and faster application deployment than VMs. The document outlines how F5 supports using containers and integrating with Docker for application delivery and security services. It describes Docker networking and how F5 solutions can provide services like load balancing within Docker container environments.
Basic Idea
Develop a build system that leverages Docker for implementing continuous integration/deployment(CI/CD) pipeline. A git commit must kick off packaging a Docker Image and provisioning it in a VM.
A git based commit should be used for starting of a build for a docker image which would then be run and provisioned in a Virtual Machine. After every commit a series of test cases is then run on the code to ensure the correctness of the code. After all the test-cases pass, the image gets updated on docker-hub registry, and a VM gets provisioned which can then run the software directly (after pulling the image from the docker-hub).
This entire process ensures that the most recent and updated version of the code is available to the person who is using the software and this speeds up the overall process by at least 2-3 folds.
Control/DCD and Control/SE are software tools that can help with migrating existing COBOL applications to newer Enterprise COBOL compilers. Control/DCD runs in batch mode on one or all programs, while Control/SE allows interactive processing of individual programs. These tools provide pre-compilation analysis of code to help identify issues during migration, as recompiling old COBOL programs without documentation risks introducing logic errors or reopening old bugs. They can help large organizations that rely heavily on legacy mainframe COBOL applications but now use offshore contractors for development and maintenance.

Crossing the river by feeling the stones from legacy to cloud native applica...OPNFV
Doug Smith, Red Hat, Inc, Gergely Csatari, Nokia
There is an anecdote about a tourist lost in the middle of the countryside in Ireland, who pulls over and asks a local, "How can I get to Galway from here?" To which the local, after thinking for some time, responds, "If I was going to Galway, I wouldn't start from here at all."
Cloud native application development can feel like that sometimes, especially in the telecom industry. I have an application, it's running fine on a bare metal server, and now I am expected to make it resilient, scale-out, cloud native, microservice architecture, buzzword compliant. But how do you get there from where you are?
This presentation will present the hero's quest, identifying the key constraint to cloud resiliency at each stage, and identifying measures for addressing them. By showing the evolution story from the perspective of two applications, including a real telecom application, this presentation addresses the practical problems. The approach is not "rewrite your app from scratch", it is refactoring for incremental improvements.
Doug and Gergely will address the automation of application deployment and configuration, separation of state from behaviour, clustering, handling storage for cloud native applications, monitoring and event management, and container orchestration, so that, at each step along the journey, you know what problem you are solving, and how to get to the next step from where you are.
This presentation is in addition to a series of workshops held at the summit sponsored by the Cloud Native Computing Foundation and organized by Dave Neary, and includes a short summary of the topics presented in those workshops in addition to the perspectives on how to complete the quest to cloud native applications.
Docker allows creating isolated environments called containers from images. Containers provide a standard way to develop, ship, and run applications. The document discusses how Docker can be used for scientific computing including running different versions of software, automating computations, sharing research environments and results, and providing isolated development environments for users through Docker IaaS tools. K-scope is a code analysis tool that previously required complex installation of its Omni XMP dependency, but could now be run as a containerized application to simplify deployment.
DockerCon - The missing piece : when Docker networking unleashes software arc...Laurent Grangeau
This document discusses how Docker networking and volumes features have enabled new application architectures. Docker now provides building blocks for compute, storage, transport and topology that allow applications to be designed as interconnected objects. This represents a shift to an object-oriented infrastructure model. The document also discusses how application networking and security paradigms must shift accordingly, with security becoming an application concern and networks designed around application topologies rather than physical infrastructure. A demo application is presented using Docker features to implement a microservices architecture with resilience, scalability and isolation between tiers.
The missing piece : when Docker networking and services finally unleashes so...Adrien Blind
Docker now provides several building blocks, combining engine, clustering, and componentization, while the new networking and service features enable many new usecases such as multi-tenancy. In this session, you will first discover the new experimental networking and service features expected soon, and then drift rapidly to software architecture, explaining how a complete Docker stack unleashes microservices paradigms.
The first part of the talk will introduce what SDNs and service registries are to the audience and will cover corresponding network & service experimental features of docker accordingly, with a technical focus. For instance, it explains how to create an overlay network of top of a swarm cluster or how to publish services.
The second part of the talk moves from infrastructure to application concerns, explaining that application architecture paradigms are shifting. In particular, we discuss the growing porosity of companies’s IS (especially due to massive use of cloud services) drifting security boundaries from the global IS perimeter, to the application shape. We also remind that traditional SOA patterns leveraging on buses (ie. ESBs & ETLs) are being replaced by microservices promoting more direct, full-mesh, interactions. To get the picture really complete, we’ll also rapidely remind other trends and shifts which are already covered by other docker components: scalability & resiliency to be supported by the apps themselves, fine-grained applications, or even infrastructure commoditization…
Most of all, the last part depicts a concrete, state-of-the-art application, applying all the properties discussed previously, and leveraging on a multi-tenant docker full stack using new networking and services features, in addition to traditional swarm, compose, and engine components. And just because we say it doesn’t mean it’s true, we’ll be happy to demonstrate this live !
2. The Current Paradigm
No one today would argue against the fact that Linux has taken the embedded Real
Time Operating System (RTOS) space by storm. More and more applications that
historically required either a commercially available RTOS, or one that was internally
created and maintained, are being replaced with a Linux-based platform.
The reasons for this movement are varied from one company to the next, but some of
the most common factors are:
1. The availability of source code to the Operating System
2. A wealth of device drivers and communication stacks
3. An increasingly available pool of software engineers that are Linux proficient
4. A perceived cost advantage achieved with removal of the OS royalty component
from the products’ bill of materials
5. Semiconductor suppliers now provide a Linux port to their SoC based hardware
reference platform, along with tool chains and a reference distribution
To take full advantage of the Linux operating system, Original Equipment Manufacturers
(OEMs) have a choice of engaging with a commercial Linux vendor or adding additional
engineering capability in-house. Both models have proven successful, but each carries
its own specific costs.
Regardless of the direction the OEM chooses, the typical debug model available for
their engineers is the same…a command line-based, client server environment based
on GDB (GNU Debugger). This model is illustrated in Figure 1, which depicts an
instantiation of GDBSERVER attached and running on each Linux process under debug
on the target. Each GDBSERVER is communicating with the host through an Ethernet
port.
In addition, it is important to understand that in this approach to Linux debug, the
standard Linux kernel is replaced with a “static” version specifically built with debugging
code instrumented throughout. In addition and with only a few exceptions, all debug
communication to the target via KGDB is limited to an RS232 serial link.
This approach provides an additional challenge to the developer that is using the
instrumented version of the Linux kernel by actually altering the performance of the
target under debug from the “released version” that will eventually ship with the product.
3. Figure 1: Standard Linux Debug Model
While this is by default the accepted Linux debug environment, there are some well
understood limitations to this approach. For example, applications that consist of
multiple processes will require multiple copies of GDBSERVER running in the often
limited target memory. This can affect the performance of the target under debug.
There have been cases of a 50%+ degradation of target performance.
Even in the best case scenario where all kernel instrumentations and communication
channels are available, there are still areas of the code that are inherently inaccessible
under this debugging paradigm. The illustrated “problem” areas in Figure 2 have
presented multiple challenges to kernel and application developers. These areas
include the large amount of threads under each process and kernel loadable modules
that are code and data position independent. While it is possible for skilled developers
to scaffold an environment based on existing technologies to address the debugging
needs in these areas, such an environment has been shown to be very user-unfriendly
and non-scaleable under load.
Consider the case of Linux kernel loadable modules, which consist of an initialization
routine to be invoked at module loading time. Current debug paradigms suggest that
such modules be loaded, and their code and data offsets then be adjusted (manually
and automatically) within the debugger. However, by this time, the initialization code of
the module has already been executed and there is no possible way to debug a
problem in this area of the code. Another use scenario involves shared libraries, which
are often not handled well by GDBSERVER or equivalents.
4. Given these obstacles, it is not uncommon that many engineers to resort to printf (user
space) and printk (kernel space) as their primary debugging aids. Not withstanding the
“ugliness” issues and time overhead of recompiling and linking in these messages, it is
very common for such debug “instrumentations” to sufficiently skew the behavior of the
code in a manner that leads to different behaviors in the program, with or without such
code in place.

Figure 2: The “Problem” Areas
The Arriba Debugger: A Holistic Approach to Debugging Linux
The Arriba Debugger is designed from the ground up to provide a holistic approach to
debugging embedded Linux and to be completely agnostic to the hardware platform
architecture or version of Linux under development. In place of GDBSERVER and
KGDB, VMON (a dynamically loadable, demand-based debug agent) runs on the
embedded Linux target. Communicating with the Arriba Debugger on the host, VMON
provides total visibility of the Linux target, from user-level threads to the static kernel.
The VMON module has a very small memory footprint and even when active, has an
almost immeasurable performance impact on the running system. At less than 250Kb
in size, VMON is able to provide end-to-end debugging of the target over a single
Ethernet connection.
5. Figure 3: The Arriba Solution
Arriba = “No Problem” Areas
“No Problem” 1 - Loadable Modules
Through the Arriba Debugger, VMON can be configured to signal the host when a
kernel module of a given property is loaded on the target. Upon the reception of this
signal, the Arriba Debugger will automatically and correctly load the symbol information
of the respective module, and place control at the entry point to the module initialization
function. The user can now have full debug control of the module in question over a
high-speed Ethernet link.
Traditionally, debugging of the Linux kernel or module (when it’s possible) is
accomplished with KGDB or JTAG, which completely halts the target under debug. In
contrast, an important feature of VMON is its ability to provide the same level of
debugging non-preemptively. In other words, the Linux kernel on the target continues to
handle inbound and outbound network traffic, multimedia data, and other time-critical
activities that are crucial in maintaining the appearance of normal execution to the
outside world. This ability is critical to many data and media-centric applications such
as set-top boxes, digital media appliances, and high-speed networking switches and
routers.
“No Problem” 2: Debugging of Multiple Processes; Parent/Child Processes
In many instances, Linux application programmers need to create applications that
involve multiple processes. Such processes are spawned from a single parent process
6. earlier in the application initialization sequence. A frequent challenge revolves around
the need to set breakpoint(s) in the child process and eventually hit such breakpoints
when the child process is created and running. Straightforward as it may sound; this is
an unsupported use-case with any debugging tools for Linux today, embedded or
otherwise. As a workaround, developers often find themselves manually inserting
instrumented code in the child process with an infinite loop that is gated by a variable
initially set to ‘true’. This enables debugging tools such as GDBSERVER to attach to
the child process in question, change the value of the gating variable to ‘false’ to
unblock to loop, and resume debugging.
Because VMON has ultimate visibility into the Linux target, events such as process
creations result in a notifying signal being sent to the Arriba Debugger on the host. The
Arriba Debugger, upon determining that a breakpoint is pending for the child process,
transmits the proper run-control sequence to ensure that such a breakpoint is set in the
child process code space.
“No Problem” 3: Debugging Kernel Drivers and Shared Libraries… Production
Released Kernel
Depending on the scope and breadth of the application, the list of Linux debug “problem
areas” can range anywhere from the inability of the programmer to use the debug tools
on his or her deployment platforms due to footprint and performance constraints
imposed by debugging techniques, to the tedious and error-prone workarounds that
result in much wasted time and increased frustrations. The Arriba Debugger provides
an in-depth solution to these problems, and beyond.
As a final example, consider the need for programmers and field application engineers
to diagnose and fix bugs manifested in deployment. Under such conditions, the target
platform is subject to severely limited debugging and communication access. VMON as
a dynamically loadable module can be configured to be launched on already-deployed
systems. Thus, VMON, with its ability to effectively debug and diagnose such systems
with minimal intrusion, has time and time again proven to be an indispensable tool
through all stages of the product lifecycle.
Eclipse Integrated Development Environment (IDE) Plug-in Support:
Viosoft Corporation recently announced an enhancement to the Arriba Debugger to
support the latest open source Eclipse environment. The powerful Eclipse based
Integrated Development Environment (IDE) is the cockpit for existing and future tools for
developing your Linux based design. This seamless integration with Eclipse provides
the developer with a complete Linux development and debug environment.
In addition to the Arriba Linux Debugger, there is also a new profiling tool called the
Arriba Linux Event Analyzer (LEA) that is also a plug in to an Eclipse IDE. This new tool
provides the ability to see all Linux events occurring on the target by capturing the
information and displaying them in a time domain format. The Arriba LEA collects and
provides a significant amount of information about the Linux system including context
switches among processes and threads, signals, and elapsed execution time.
Simultaneously, LEA incurs a minimal impact on the overall CPU cycles and memory
footprint. LEA light-weighted-ness, coupled with its ability to dynamically add and
remove instrumentation points on a production-ready running Linux system make LEA
7. an ideal performance analysis and debugging tool, both for in-house development and
for field deployment.
An example result of this format is shown in Figure 4 below. Within this view, the user
can zoom in and out to gain a detailed understanding of how their code behaves and the
tasks execute in both the kernel and user space areas. Providing the ability to measure
latencies, response times to external events and even the load each event represents
on the running system. This information is also available in a “raw” format that can
easily be imported to Microsoft Excel for additional post processing and analysis.
Because no two end-user applications are alike, each developer or team of developers
within organization is likely to be interested in collecting and visualizing different aspects
of the system with LEA. The needs for having an open-ended analysis tools leads to a
design of LEA that is highly customizable. By creating and deploying their own kernel
module plug-in to LEA, developers can easily and rapidly gain a level of visibility into
their applications and system that not possible with other close-ended tools.
LEA uses the same instrumentation technology employed by VMON in the Arriba Linux
Debugger, which means that no debug patches or special compilation of the Linux
kernel is required. This capability makes LEA an ideal choice for deployment on
production systems.
The combination of the Arriba Linux Debugger, Arriba LEA and the Eclipse IDE provides
our customers with a very comprehensive and powerful Linux development
environment. This solution was designed to shorten our customers’ time to market while
providing developers the ability to create a level of quality in their code that is
unavailable from any other solution.
