During fuzzing, we are trying to crash the program, thus we need additional probes to observe the program's behaviour.Īdditional knowledge about program state can be exploited as a feedback loop for generating new input vectors. However, programs usually process different inputs at different speeds, which can give us some insight into the program's behavior. What can be done to make fuzzing more effective? If we think about fuzzing as a process, where we place data into the input of the program (which is a black box), and we can only interact via input, not much more can be done. The simplest 'fuzzer' can be written in few lines of bash, by getting N bytes from /dev/rand, and putting them to the program as a parameter. This input can be random, or it can be generated in some way that makes it unexpected form standard execution perspective. The easy way to describe fuzzing is to compare it to the process of unit testing a program, but with different input. News Roundup Write your own fuzzer for NetBSD kernel! Workstation needs, especially for a primary workstation, are greatly different and the small things end up mattering most. I just haven’t used it as a workstation (outside of a virtual machine) in over 10 years, but have used it for servers. The biggest time in my life was the early 2000s (I was even the Python port maintainer for a bit), where I not only used it for my workstation, but also for production servers and network devices. I’ve been using it off and on for over 20 years. I do hope you give OpenBSD a shot as your workstation, especially if it has been a while. I don’t truly care, but wanted to share in case it could be useful to you. I will try to detail what my reasons are for going with OpenBSD (instead of GNU/Linux, NetBSD, or FreeBSD of which I’m comfortable using without issue), challenges and frustrations I’ve encountered, and what my opinions are along the way.ĭisclaimer: in this post, I’m speaking about what is my opinion, and I’m not trying to convince you to use OpenBSD or anything else. Additionally, I do care about security and non-bloat in my personal operating systems (business needs can have different priorities, to be clear). Why OpenBSD? Simply because it is the best tool for the job for me for my new-to-me Lenovo Thinkpad T420. ![]() Deprecation warnings have been added for weaker algorithms when creating geli(8) providers.Warnings have been added for IPSec algorithms deprecated in RFC 8221.Warnings for features deprecated in future releases will now be printed on all FreeBSD versions.Several network driver firmware updates. ![]() Several feature additions and updates to userland applications.The kernel will now log the jail(8) ID when logging a process exit.The GNOME desktop environment has been updated to version 3.28.The KDE desktop environment has been updated to version 5.15.3.The pkg(8) utility has been updated to version 1.10.5.The loader(8) has been updated to extend geli(8) support to all architectures.The ZFS filesystem has been updated to implement parallel mounting.OpenSSL has been updated to version 1.0.2s.The ELF Tool Chain has been updated to version r3614.The clang, llvm, lld, lldb, and compiler-rt utilities as well as libc++ have been updated to upstream version 8.0.0.This is the fourth release of the stable/11 branch.
