  • t2k17 Hackathon report: Ken Westerback on dhclient progress, developer herding
  • A return-oriented programming defense from OpenBSD

    Stack-smashing attacks have a long history; they featured, for example, as a core part of the Morris worm back in 1988. Restrictions on executing code on the stack have, to a great extent, put an end to such simple attacks, but that does not mean that stack-smashing attacks are no longer a threat. Return-oriented programming (ROP) has become a common technique for compromising systems via a stack-smashing vulnerability. There are various schemes out there for defeating ROP attacks, but a mechanism called "RETGUARD" that is being implemented in OpenBSD is notable for its relative simplicity.

    In a classic stack-smashing attack, the attack code would be written directly to the stack and executed there. Most modern systems do not allow execution of on-stack code, though, so this kind of attack will be ineffective. The stack does affect code execution, though, in that the call chain is stored there; when a function executes a "return" instruction, the address to return to is taken from the stack. An attacker who can overwrite the stack can, thus, force a function to "return" to an arbitrary location.

  • LLVM 5.0.0 Release

    This release is the result of the community's work over the past six months, including: C++17 support, co-routines, improved optimizations, new compiler warnings, many bug fixes, and more.

  • LLVM 5.0 Released With C++17 Support, Ryzen Scheduler, AMDGPU Vega & Much More

    After delays pushed its release back by about one month, LLVM 5.0 was just released a few minutes ago along with its associated sub-projects like the Clang 5.0 C/C++ compiler.

    LLVM 5.0 features a number of improvements to the ARM and MIPS targets, greater support for the POWER ISA 3.0 in the PowerPC target, the initial AMD Ryzen (znver1) scheduler support (already improved in LLVM 6.0 SVN), support for Intel Goldmont CPUs, greater AVX-512 support, improved Silvermont/Sandybridge/Jaguar schedulers, and initial Radeon Vega (GFX9) support within the AMDGPU target.

  • Android NDK r16: Developers Should Start Using LLVM's libc++ With GCC On The Way Out

    Google has announced the availability today of the Android Native Development Kit (NDK) Release 16. This release is worth mentioning in that Google is now encouraging developers to start using libc++ as their C++ standard library.

    Moving forward, Google will only be supporting LLVM's libc++ as the C++ standard library and not supporting other STLs. The Android platform has already been using libc++ since Lollipop and now they are looking to get more application developers using this STL.

  • Google publishes its documentation style guide for developers

    Documentation is often an afterthought — especially for open-source projects. That can make it harder for newcomers to join a project, for example, and sometimes badly written documentation is worse than having no documentation at all. To help developers write better documentation, Google this week opened up its own developer-documentation style guide.

  • Trying Out FreeBSD/TrueOS On The Xeon Scalable + Tyan GT24E-B7106 Platform

    While we have tested a number of Linux distributions on Intel's new Xeon Scalable platform, here are some initial BSD tests using two Xeon Gold 6138 processors with the Tyan GT24E-B7106 1U barebones server.

  • FreeBSD Developers Tackle AMD Zen/Ryzen Temperature Monitoring Before Linux

    While Linux users of AMD's new Zen-based Ryzen/Threadripper/Epyc processors are still waiting for thermal driver support to hit the mainline Linux kernel, FreeBSD developers have already managed to produce the Zen "Family 17h" CPU thermal monitoring support on their own.

    From this FreeBSD bug report, developers have managed to get the AMD CPU temperature monitoring working for Zen processors under Linux with their existing temperature driver.

  • Trip Report: FreeBSD in China at COPU and LinuxCon

    In May of 2017, we were invited to give a talk about FreeBSD at COPU’s (China Open Source Promotional Unit) Open Source China, Open Source World Summit, which took place June 21-22, in Beijing. This was a tremendous opportunity to talk about the advantages of FreeBSD to the open source leaders and organizations interested in open source. I was honored to represent the Project and Foundation and give the presentation “FreeBSD Advantages and Applications”.

  • Trying Out AMD's Ryzen Threadripper On TrueOS, DragonFlyBSD

    Following the AMD Threadripper Linux tests of this week today I finally had a chance to try out some of the BSDs with this 16 core / 32 thread system.

    With the AMD Threadripper 1950X with Gigabyte X399 AORUS Gaming 7 is how I was running these tests. Initial targets were with TrueOS (formerly known as PC-BSD, the desktop-oriented branch of FreeBSD) and DragonFlyBSD.

  • August 2017 Development Projects Update
  • My first patch to OpenBSD

    I followed Preparing a diff and Making your first patch (OpenBSD) to submit my first OpenBSD patch. Guess what? just few hours later, dmesg source file was changed base on my code. Although the final modification is not my code, it is still a great pleasure that I contribute my own effort to help make OpenBSD better!

LWN (Now Open Access): Kernel Configuration, Linux 4.14 Merge Window, Running Android on a Mainline Graphics Stack

  • A different approach to kernel configuration
    The kernel's configuration system can be challenging to deal with; Linus Torvalds recently called it "one of the worst parts of the whole project". Thus, anything that might help users with the process of configuring a kernel build would be welcome. A talk by Junghwan Kang at the 2017 Open-Source Summit demonstrated an interesting approach, even if it's not quite ready for prime time yet. Kang is working on a Debian-based, cloud-oriented distribution; he wanted to tweak the kernel configuration to minimize the size of the kernel and, especially, to reduce its attack surface by removing features that were not needed. The problem is that the kernel is huge, and there are a lot of features that are controlled by configuration options. There are over 300 feature groups and over 20,000 configuration options in current kernels. Many of these options have complicated dependencies between them, adding to the challenge of configuring them properly.
  • The first half of the 4.14 merge window
    September 8, 2017 As of this writing, just over 8,000 non-merge changesets have been pulled into the mainline kernel repository for the 4.14 development cycle. In other words, it looks like the pace is not slowing down for this cycle either. The merge window is not yet done, but quite a few significant changes have been merged so far. Read on for a summary of the most interesting changes entering the mainline in the first half of this merge window.
  • Running Android on a mainline graphics stack
    The Android system may be based on the Linux kernel, but its developers have famously gone their own way for many other parts of the system. That includes the graphics subsystem, which avoids user-space components like X or Wayland and has special (often binary-only) kernel drivers as well. But that picture may be about to change. As Robert Foss described in his Open Source Summit North America presentation, running Android on the mainline graphics subsystem is becoming possible and brings a number of potential benefits. He started the talk by addressing the question of why one might want to use mainline graphics with Android. The core of the answer was simple enough: we use open-source software because it's better, and running mainline graphics takes us toward a fully open system. With mainline graphics, there are no proprietary blobs to deal with. That, in turn, makes it easy to run current versions of the kernel and higher-level graphics software like Mesa.

Red Hat: Ansible Tower, Patent Promise, and Shares Declining

  • Red Hat’s automation solution spreading among APAC enterprises
    Red Hat recently shared revealed its agentless automation platform is spreading among enterprises in APAC countries like Australia, China, India and Singapore. The company asserts its Ansible Tower helps enterprises cut through the complexities of modern IT environments with powerful automation capabilities that improve productivity and reduce downtime. “Today’s business demands can mean even greater complexity for many organisations. Such dynamic environments can necessitate a new approach to automation that can improve speed, scale and stability across IT environments,” says head of APAC office of technology at Red Hat, Frank Feldmann.
  • Red Hat broadens patent pledge to most open-source software
    Red Hat, the world's biggest open source company, has expanded its commitment on patents, which had originally been not to enforce its patents against free and open source software.
  • Red Hat expands Patent Promise
    Open-source software provider Red Hat has revised its Patent Promise, which was initially intended to discourage patent aggression against free and open-source software. The expanded version of the defensive patent aggregation scheme extends the zone of non-enforcement to all of Red Hat’s patents and all software under “well-recognised” open-source licenses. In its original Patent Promise in 2002, Red Hat said software patents are “inconsistent with open-source and free software”.
