Using current ELF in Ghidra instead of file on disk? #13

Open Manouchehri opened 2 years ago

Manouchehri commented 2 years ago

Right now, ghidra2dwarf.py relies on having the original ELF on disk. It ends up breaking one of my automated workflows, since my tooling cleans up samples off disk after they've been imported to Ghidra.

We should use the ElfExporter class instead to get the original ELF file. https://github.com/NationalSecurityAgency/ghidra/blob/master/Ghidra/Features/Base/src/main/java/ghidra/app/util/exporter/ElfExporter.java

Here's some examples of how to do that:

I'll do this myself, just wanted to make a ticket so I don't forget.
