Hi all. Sorry for the crosspost.
I am looking for some documentation on the structure of the stack when
an executable starts. I know the basics - argc, then argv, then envp.
What I'm interested in is what's beyond that. I've tried googling,
reading the sources in the kernel for fs/binfmt_elf.c

ENTRY:')

P.S. And what do you need it for (except curiosity) ?

It's going to be a somewhat long p.s. If you understood the problem I'm
trying to solve, skip ahead to area marked "proposed solution" for how
I'll be trying to solve it.
Here's a piece of trivia for you. /lib/ld-l

Actually, I can think of four or five reasons why it may fail, but I'll
cross those bridges when I get to them.
And if you change AT_ENTRY in the auxv you'll trick ld-linux to think
it was loaded as interprete

Could you list them ?
Let's see. Off the top of my head, these are not necessarily "won't
work" problems, but obstacles to overcome:

That's part of it, but not all of it. If the only problem was the "ps"
output, I would have lived with it. The real problem is that argv[0] is
an actual argument that some programs use.
Think of the fo
