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.
