[$] The programmer's CAD: OpenSCAD OpenSCAD is a GPLv2-licensed 3D computer-aided design (CAD) program best described as a "programmer's CAD"; it is available for Linux, Windows, several flavors of BSD, and macOS. Unlike the majority of 3D-modeling software packages which are point-and-click, the OpenSCAD website describes the project as " something like a 3D compiler", where models are generated using a scripting language. It is a unique way of approaching CAD and has many real-world applications that may be of interest. | | 7:35p |
Fuzzing the Linux kernel (x86) entry code (Oracle) The Oracle blog is putting up a series by Vegard Nossum on fuzzing the kernel's entry code; part 1and part 2are available now. " While these fuzzers effectively test the system calls themselves (and the code reachable through system calls), one thing they don't test very well is what happens at the actual transition point between userspace and the kernel. There is more to this boundary than meets the eye; it is written in assembly code and there is a lot of architectural state (CPU state) that must be verified or sanitized before the kernel can safely start executing its C code.
This blog post explores how one might go about writing a fuzzer targeting the Linux kernel entry code on x86." | | 7:51p |
X.Org Server 1.20.9 released
The X.Org project has announced the release of xorg-server version 1.20.9. Among other improvements are numerous fixes to XWayland, including a bug that could cause an infinite loop at startup as well as other potential crash fixes. The release also addresses several security issues that can "lead to local privileges elevation on systems where the X server is running privileged." Users of xorg-server are encouraged to upgrade.
