Do you need "set solib-search-path" or "set sysroot"? That "warning: Could not load shared library..." is mostly harmless (it is a bug in GDB), in the FAIL case it is not printed just because bfd_check_format() fails there. It seems logical to me this way when the 'size' parameter has been already added. Alan Modra: I was wrongly thinking that the section headers were always last when I wrote that code. (They are now! If you relink that vdso with current binutils master you won't hit this problem, but that of course doesn't help existing kernels.)

2014-04-02Handle VDSO section headers past end of pageAlan Modra1-61/+92
When a VDSO gets large enough that it doesn't entirely fit in one page, but not so large that the part described by the program header exceeds one page, then gdb/BFD doesn't read the section headers and symbol table information. This patch cures that by passing the size of the vdso to BFD, and fixes a number of other issues in the BFD code. bfd/ * elfcode.h (bfd_from_remote_memory): Add "size" parameter. Consolidate code handling possible section headers past end of segment. Don't use p_align for page size guess, instead use minpagesize. Take note of ld.so clearing section headers when p_memsz > p_filesz. Handle file header specifying no section headers. Handle zero p_align throughout. Default loadbase to zero. Add comments. Rename contents_size to high_offset, and make it a bfd_vma.
