The LLVM Memory Sanitizer support work in progress


January 03, 2018 posted by Kamil Rytarowski

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


November 30, 2017 posted by Kamil Rytarowski

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]

One year checkpoint and Thread Sanitizer update


November 01, 2017 posted by Kamil Rytarowski

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]

Kernel ASLR on amd64


October 12, 2017 posted by Maxime Villard

Recently, I completed a Kernel ASLR implementation for NetBSD-amd64, making NetBSD the first BSD system to support such a feature. Simply said, KASLR is a feature that randomizes the location of the kernel in memory, making it harder to exploit several classes of vulnerabilities, both locally (privilege escalations) and remotely (remote code executions).[Read More] [2 comments]

 

EuroBSDcon 2017: "travel notes" after the conference


October 11, 2017 posted by Leonardo Taccari

Let me tell you about my experience at EuroBSDcon 2017 in Paris, France. We will see what was presented during the NetBSD developer summit on Friday and then we will give a look to all of the NetBSD and pkgsrc presentations given during the conference session on Saturday and Sunday. Of course, a lot of fun also happened on the "hall track", the several breaks during the conference and the dinners we had together with other *BSD developers and community! This is difficult to describe and I will try to just share some part of that with photographs that we have taken. I can just say that it was a really beautiful experience, I had a great time with others and, after coming back home... ...I miss all of that! :) So, if you have never been in any BSD conferences I strongly suggest you to go to the next ones, so please stay tuned via NetBSD Events. Being there this is probably the only way to understand these feelings!
