2014-01-21Don't check shared/export_dynamic/ref_dynamic for type mismatchH.J. Lu2-3/+7
There is nothing linker can do when a type mismatched default definition are made dynamic by info->shared, info->export_dynamic or h->ref_dynamic. But we do want to avoid exporting it when building PIE. Let's remove those checks. bfd/ PR ld/2404 * elflink.c (_bfd_elf_merge_symbol): Don't check info->shared, info->export_dynamic, nor !h->ref_dynamic for type mismatch when adding the default version. ld/testsuite/ PR ld/2404 * ld-elf/shared.exp: Add a PIE test for PR ld/2404.

When a symbol is absolute, this code in mips_elf_record_got_page_entry entry = bfd_zalloc (sec->owner, sizeof (*entry)); segfaults. sec == bfd_abs_section_ptr and sec->owner == NULL. * elfxx-mips.c (mips_elf_record_got_page_entry): Pass in a mips_elf_traverse_got_arg* rather than mips_got_info*. Adjust caller. Alloc on output_bfd rather than symbol section owner.

2014-01-15Revert the last changeH.J. Lu3-10/+10
It has been fixed by commit 4199e3b8669d0a36448687850374fdc2ad7240b6 Author: Alan Modra <amodra@gmail.com> Date: Wed Jan 15 21:50:55 2014 +1030 non-PIC references to __ehdr_start in pie and shared Rather than hacking every backend to not discard dynamic relocations against an undefined hidden __ehdr_start, make it appear to be defined early. We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value. (In some cases we want to leave the symbol undefined, for example, when the ELF header isn't loaded, and we don't have this infomation available in before_allocation.) * elf32-i386.c (elf_i386_allocate_dynrelocs): Revert the last change. * elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewise.

2014-01-13Error on shared lib call to @local ifuncAlan Modra1-2/+19
On powerpc32, making ifuncs have non-default visibility in shared libraries or pies can result in runtime failures. The problem is that if gcc is told that a given function has non-default visibility, then calls to that function are assumed to be local (which is true) and thus need not go via a plt call stub (which is false for ifunc). If the caller has no other reason to set up the got pointer (r30), code won't be emitted to do so. However, a pic plt call stub makes use of r30 to load the plt entry. So a call to an ifunc, which always needs a plt entry, will fail. This patch makes ld emit an error for the problem case, and allows calls to non-default visibility ifuncs to work in normal executables. I also fix some cases where ifuncs fail when using the old bss-plt. * elf32-ppc.c (ppc_elf_check_relocs): For @local call to ifunc, error when shared and force a plt call otherwise. (ppc_elf_size_dynamic_sections): Don't emit DT_PPC_GOT unless plt_type == PLT_NEW. (ppc_elf_relocate_section): Add missing test to resolve ifuncs to the appropriate call stub.

2014-01-08Adjust LOAD segment to generate GNU_RELRO segmentH.J. Lu2-5/+46
This patch fixes 2 GNU_RELRO segment bugs: 1. lang_size_sections didn't properly align base to the maximum alignment power of sections between DATA_SEGMENT_ALIGN and DATA_SEGMENT_RELRO_END. 2. ld failed to adjust LOAD segment to generate GNU_RELRO segment when LOAD segment doesn't fit GNU_RELRO segment. This is https://sourceware.org/bugzilla/show_bug.cgi?id=14207 We "fixed" ld by not generating GNU_RELRO segment. This patch adjusts LOAD segment to generate GNU_RELRO segment. It fixes PR ld/16322 and at the same time it also fixes PR binutils/16323 since now we can adjust LOAD segment if it is too small. bfd/ PR ld/14207 PR ld/16322 PR binutils/16323 * elf.c (_bfd_elf_map_sections_to_segments): Don't check section size for PT_GNU_RELRO segment.
