2016-12-29link_hash_copy_indirect and symbol flagsAlan Modra11-47/+63
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among other things, modified _bfd_elf_link_hash_copy_indirect to not copy ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt and pointer_equality_needed when setting up an indirect non-versioned symbol pointing to a non-default versioned symbol. I didn't notice at the time, but the pr18720 testcase fails on hppa-linux with "internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933 in elf32_hppa_relocate_section". Now hppa-linux creates entries in the plt even for local functions, if they are referenced using plabel (function pointer) relocations. So needs_plt is set for foo when processing pr18720a.o. When the aliases in pr28720b.o are processed, we get an indirection from foo to foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol that is used after that point, no plt entry is made for foo and we bomb when relocating the plabel. As shown by the hppa-linux scenario, needs_plt should be copied even for non-default versioned symbols. I believe all of the others ought to be copied too, with the exception of ref_dynamic. Not copying ref_dynamic is right because if a shared lib references "foo" it should not be satisfied by any non-default version "foo@FOO". * elflink.c (_bfd_elf_link_hash_copy_indirect): Only omit copying one flag, ref_dynamic, when versioned_hidden. * elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise. * elf32-hppa.c (elf32_hppa_copy_indirect_symbol): Use same logic for copying weakdef flags.

2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra29-154/+521
Variables defined in shared libraries are copied into an executable's .bss section when code in the executable is non-PIC and thus would require dynamic text relocations to access the variable directly in the shared library. Recent x86 toolchains also copy variables into the executable to gain a small speed improvement. The problem is that if the variable was originally read-only, the copy in .bss is writable, potentially opening a security hole. This patch cures that problem by putting the copy in a section that becomes read-only after ld.so relocation, provided -z relro is in force. The patch also fixes a microblaze linker segfault on attempting to use dynamic bss variables. bfd/ PR ld/20995 * elf-bfd.h (struct elf_link_hash_table): Add sdynrelro and sreldynrelro.

2016-12-23MIPS/BFD: Remove EI_ABIVERSION 5 allocation for PT_GNU_STACK supportMaciej W. Rozycki2-3/+5
Revert commit 17733f5be961 ("Increment the ABIVERSION to 5 for MIPS objects with non-executable stacks.") and remove EI_ABIVERSION 5 allocation for PT_GNU_STACK support, which has not made it to glibc and will be reassigned. bfd/ * bfd/elfxx-mips.c (_bfd_mips_post_process_headers): Revert 2016-02-23 change and remove EI_ABIVERSION 5 support.

This stops an --enable-targets selection affecting the main target in regards to forcing 64-bit archives. It also means mips64 and s390x will revert to binutils-2.25 and binutils-2.26 behaviour of not forcing 64-bit archives at least in the common case when plugins were enabled.
