[Bug libc/5929] New: VALID_ELF_HEADER is not used for the executable

[drow at sources dot redhat dot com]

I'm working on a project that involves bumping the EI_ABIVERSION, since new
binaries require loader support.  We wanted a sensible error message when using
an old loader, but it doesn't work unless you run ld.so by hand:

$ /lib/ld.so.1 ./newtest.exe
./newtest.exe: error while loading shared libraries: ./newtest.exe: ELF file ABI
version invalid
$ ./newtest.exe
Segmentation fault (core dumped)

VALID_ELF_HEADER is only used when loading a new file; it is never applied to
the mapped executable when ld.so is the interpreter.

It's the kernel's job.  I'm not slowing things down because of requirements like
your's.

There's nothing wrong with the file from the kernel's point of view.  The kernel
doesn't check ELF version or ABI version at all.  The file uses ELF features
that ld.so doesn't support.

Oh well, leaving WONTFIX.
