Now let me quote the relevant part of _my_
spec:

- If you use a private file-backed mapping, then it shouldn't be
   modified by hands before passing to dlmem(). I.e. you can't apply
   mprotect() to it to change protection bits, and you can't apply
   memmove() to it to move the solib to the beginning of the buffer,
   and so on. dlmem() can only work with "virgin" private file-backed
   mappings.


That's what _my_ spec says.
Why can't we just settle on a fact that anything
that contradicts my spec, be it taken from some
10-years-old thread or from elsewhere, cannot
be used as an argument when judging my API?
Why can't we settle on a fact that even the
attempts to do so are unacceptable, especially
the repetitive attempts?
We discuss my spec, so replacing its parts during
the discussion, is counter-productive.

Because the reviewer must not operate on
some other spec when judging my spec. If
the reviewer thinks his spec describes my
proposed implementation better than my
own spec, then he should better actually try
to prove that. But at the end I presented my
own proof that my impl is conforming:
https://sourceware.org/pipermail/libc-alpha/2023-March/146742.html

And now the question is simple: what else
should be done on my side to have that
case finally resolved? Code up some other
proof? Write more clearly in a spec that no
elf parsing is needed?
Its a simple question, just what should I do?
You tell - I do.
