Core dump note section

Question

Following my question about manually generating a core dump file, I decided to dive into it and get my hands dirty.

I am able to build the basic core dump structure

Answer 1

Can someone give me directions on how is structured the Notes section?

The notes section is a concatenation of variable-sized note records. Each note record begins with ElfW(Nhdr) structure, followed by (variable sized) name (of length .n_namesz, padded so total size of name on disk is divisible by 4) and data (of length .n_descsz, similarly padded).
