    Subject[PATCH 0/2] fs, elf: get rid of MAP_FIXED from the loader
    Date
    Hi,
    the previous discussion didn't really show any hard requirement for
    MAP_FIXED usage for the elf segments mapping. I have spent some more
    time studying the code (thanks to Qualys for their insight) and
    concluded that the current MAP_FIXED usage is rather fragile and not
    really needed. The first patch replaces it by a hint mmaping and failing
    rather than silently corrupt an existing memory and the second patch
    removes MAP_FIXED for the initial segment mapping because this shouldn't
    be really needed either, I would even call it wrong.
    Anyway, more details are in the changelog of patches. I will really
    appreciate any feedback.

    This has passed some testing with PIE/PIC binaries running in the loop
    without any negative side effects detected.
