Subject: [musl] Getting access to section data during dynlink.c

Hi!

I'd like to read some section data during dynlink.c
Does anyone have any good suggestions on the best way to do so?
I believe most ELF files ask for the load to start from the start of the
ELF file.

I see in dynlink.c the kernel sends AT_PHDR as an auxiliary vector --
Should I try applying a fixed offset from it to get to the start of the
ehdr ?

Any advice is appreciated.

Please include me in the CC for the reply.
I can't recall if I've subscribed.
