Description H.J. Lu 2015-03-25 15:39:24 UTC

On x86-64, I got bogus error:

[hjl@gnu-tools-1 tests]$ eu-elflint /bin/ls
section [10] '.rela.plt': relocation 0: offset out of bounds
section [10] '.rela.plt': relocation 1: offset out of bounds
section [10] '.rela.plt': relocation 2: offset out of bounds
section [10] '.rela.plt': relocation 3: offset out of bounds
...

sh_info should be ignored for dynamic relocation since
r_offset isn't section relative.

Comment 1 Mark Wielaard 2015-03-26 08:54:07 UTC

I believe that is a bug in GNU binutils ld. When using eu-elflint --gnu-ld we ignore some known issues of that linker. See https://fedorahosted.org/elfutils/wiki/ElflintGNU

Comment 2 H.J. Lu 2015-03-26 12:15:16 UTC

Given a binary, we may not know which linker built it.  It makes
eu-elflint --gnu-ld kind of useless.

Comment 3 Mark Wielaard 2015-03-26 14:22:24 UTC

In general systems use one linker and linkers often share the same set of bugs with GNU ld.
