Description Roland McGrath 2007-05-18 04:24:30 UTC
eu-elflint --gnu-ld complains about a prelinked ET_EXEC when it had .bss split
into .dynbss+.bss, because .dynsym symbols for bss symbols all refer to one
section.  Symbols that are now in .dynbss should have their st_shndx fields set
to the index of .dynbss.  This does not affect the dynamic linker, but does
leave the symbol table in a nonkosher state.  The same applies to .symtab in
unstripped binaries for prelink, I expect.  Similarly, the STT_SECTION symbols
for allocated sections that were moved around by prelink should have their
st_value's updated.  Some linkers have produced section symbols even in .dynsym,
so best to be thorough (or else edit the STT_SECTION and any other unreferenced
local symbols out entirely if you are doing that sort of thing in prelink). 
It's possible that some debugger consumer would like to use st_shndx and can be
confused by wrong indices, though most likely it's only elflint that cares.

This bug is open for a Fedora version that is no longer maintained and
will not be fixed by Fedora. Therefore we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen thus bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

In the source it looks like this was fixed a while ago.
