Software does not, by itself, change the world

Andy Wingo wrote some thoughts on rms and gnu. Although I don’t agree with the description of RMS as doing nothing for GNU, the part describing GNU itself is spot on: Software does not, by itself, change the world; it lacks agency. It is the people that maintain, grow, adapt, and build the software that […]

elfutils 0.177 released with eu-elfclassify

elfutils 0.177 was released with various bug fixes (if you ever had issues updating > 2GB ELF files using libelf, this release is for you!) and some new features.

bzip2 and the CVE that wasn’t

Compiling with the GCC sanitizers and then fuzzing the resulting binaries might find real bugs. But not all such bugs are security issues. When a CVE is filed there is some pressure to treat such an issue with urgency and push out a fix as soon as possible. But taking your time and making sure […]

bzip2 1.0.8

We are happy to announce the release of bzip2 1.0.8. This is a fixup release because the CVE-2019-12900 fix in bzip2 1.0.7 was too strict and might have prevented decompression of some files that earlier bzip2 versions could decompress. And it contains a few more patches from various distros and forks. bzip2 1.0.8 contains the […]

glibc 2.28 cleanup – no more memory leaks

glibc already released 2.29, but I was still on a much older version and hadn’t noticed 2.28 (which is the version that is in RHEL8) has a really nice fix for people who obsess about memory leaks. When running valgrind to track memory leaks you might have noticed that there are sometimes some glibc data […]

Valgrind 3.15.0 with improved DHAT heap profiler

Julian Seward released valgrind 3.15.0 which updates support for existing platforms and adds a major overhaul of the DHAT heap profiler.  There are, as ever, many refinements and bug fixes.  The release notes give more details. Nicholas Nethercote used the old experimental DHAT tool a lot while profiling the Rust compiler and then decided to […]

Building GDB from GIT

Since the GNU Toolchain has many shared modules it sometimes feels like you have to rebuild everything (assembler, linker, binutils tools, debugger, simulators, etc.) just to get one of the latest tools from source. Having all this reusable shared code is fun, but it does make build times a bit long. Luckily most of the […]
