NetBSD 7.1.2 released

The NetBSD Project is pleased to announce NetBSD 7.1.2, the second security/bugfix update of the NetBSD 7.1 release branch. It represents a selected subset of fixes deemed important for security or stability reasons. If you are running an earlier release of NetBSD, we strongly suggest updating to 7.1.2.

For more details, please see the release notes.

Complete source and binaries for NetBSD are available for download at many sites around the world. A list of download sites providing FTP, AnonCVS, and other services may be found at http://www.NetBSD.org/mirrors/.

LLDB restoration and return to ptrace(2)

I've managed to unbreak the LLDB debugger as much as possible with the current kernel and hit problems with ptrace(2) that are causing issues with further work on proper NetBSD support. Meanwhile, I've upstreamed all the planned NetBSD patches to sanitizers and helped other BSDs to gain better or initial support.[Read More] [0 comments]

The LLVM Sanitizers stage accomplished

I've managed to get the Memory Sanitizer to work for the elementary base system utilities, like ps(1), awk(1) and ksh(1). This means that the toolchain is ready for tests and improvements. I've iterated over the base system utilities and I looked for bugs, both in programs and in sanitizers. The number of detected bugs in the userland programs was low, there merely was one reading of an uninitialized variable in ps(1).[Read More] [0 comments]

 

The LLVM Memory Sanitizer support work in progress

In the past 31 days, I've managed to get the core functionality of MSan to work. This is an uninitialized memory usage detector. MSan is a special sanitizer because it requires knowledge of every entry to the basesystem library and every entry to the kernel through public interfaces. This is mandatory in order to mark memory regions as initialized.[Read More] [0 comments]

The LLVM Thread Sanitizer has been ported to NetBSD

During the past month I've finished my work on TSan for NetBSD/amd64. There are still few minor issues, although the Sanitizer is already suitable for real applications and is stable. I was able to build real applications like LLDB against TSan and get it to work to find real threading problems.

The process of stabilization and fixing TSan was challenging as there are intermixed types of issues that resulted in one big random breakage bug that is difficult to analyze. Software debuggers need more work with threaded programs, so this was like a chicken-egg problem, to debug debugging utilities.[Read More] [0 comments]

NetBSD on Allwinner SoCs Update

Since the last update, we've made a number of improvements to the NetBSD Allwinner port. The SUNXI kernel has grown support for 8 new SoCs, and we added many new device drivers to the source repository.

One year checkpoint and Thread Sanitizer update

The past year has been started with bugfixes and the development of regression tests for ptrace(2) and related kernel features, as well as the continuation of bringing LLDB support and LLVM sanitizers (ASan + UBsan and partial TSan + Msan) to NetBSD.
My plan for the next year is to finish implementing TSan and MSan support, followed by a long run of bug fixes for LLDB, ptrace(2), and other related kernel subsystems[Read More] [1 comment]

 

Google Summer of Code 2017

NetBSD participated in the 2017 edition of Google of Summer of Code with 3 students. All of the students finished their projects successfully. The following links report about their activities:

• Leonardo Taccari: Add multi-packages support to pkgsrc
• Maya Rashish: LFS cleanup
• Utkarsh Anand: Make Anita support multiple virtual machine systems

Congratulations to the students for finishing their projects successfully, and thanks to Google for sponsoring! [0 comments]
