Anatomy of an ELF core file
Published:
The Executable and Linkable Format (ELF) 🧝 is used for compilation outputs (.o files), executables, shared libraries and core dumps. The first cases are documented in the System V ABI specification and the Tools Interface Standard (TIS) ELF specification but there does not seem to be much documentation about the usage of the ELF format for core dumps. Here are some notes on this.
ELF loading and dynamic linking
Published:
Some notes on ELF 🧝 loading and dynamic linking mainly for GNU userland (ld.so, libc, libdl) running on top of the Linux kernel. Some prior knowlegde on the topic (virtual memory, shared objects, sections) might be useful to understand this.

Another different approach would be to use a dynamic-linker isolation of the different components of the process. Here is a summary of the goals, problems and design issues surrounding these topics.
