[Elftoolchain-developers] how to change note in a core file

[Chuck T. <ct...@gm...>]

Hi

I'm trying to use libelf to modify the file created from a core dump
but am struggling with the right approach to use. Parts of the
application work fine (e.g. modifying the ELF header), but modifying
the Notes section is problematic. One attempt was to use the pointer
returned from elf_rawfile() directly, but writing to this segfaults (I
think) because libelf mmap's the file read-only. Are there any other
approaches people would recommend? TIA.
