2017-04-23PR 21412, get_reloc_section assumes .rel/.rela name for SHT_REL/RELA.Alan Modra1-0/+15
This patch fixes an assumption made by code that runs for objcopy and strip, that SHT_REL/SHR_RELA sections are always named starting with a .rel/.rela prefix. I'm also modifying the interface for elf_backend_get_reloc_section, so any backend function just needs to handle name mapping. PR 21412 * elf-bfd.h (struct elf_backend_data <get_reloc_section>): Change parameters and comment. (_bfd_elf_get_reloc_section): Delete.

2017-04-21i386: Avoid dynamic symbol with GOT reference in PIEH.J. Lu1-0/+14
GOT reference to global symbol in PIE will lead to dynamic symbol. It becomes a problem when "time" or "times" is defined as a variable in an executable, clashing with functions of the same name in libc. If a symbol isn't undefined weak symbol, don't make it dynamic in PIE and generate R_386_RELATIVE relocation. bfd/ PR ld/21402 * elf32-i386.c (elf_i386_link_hash_entry): Add no_finish_dynamic_symbol.

2017-04-21Require --no-dynamic-linker with -static -E/--dynamic-listH.J. Lu1-0/+8
When -static -E/--dynamic-list are passed to linker, linker may create executable with dynamic sections which aren't supported by run-time. We require --no-dynamic-linker together with -static -E/--dynamic-list before adding dynamic symbol table to static executable. bfd/ PR ld/19617 PR ld/21086 * elflink.c (elf_link_add_object_symbols): Require --no-dynamic-linker with -E/--dynamic-list when creating dynamic sections. ld/ PR ld/19617 PR ld/21086 * testsuite/ld-elf/pr19617a.d: Pass --no-dynamic-linker to ld. * testsuite/ld-elf/pr19617b.d: Likewise. * testsuite/ld-elf/pr19617c.d: Likewise. *testsuite/ld-i386/pr19636-4d.d: Likewise. * testsuite/ld-elf/readelf.exp: Pass --no-dynamic-linker to ld with --export-dynamic. * testsuite/ld-elf/shared.exp: Pass --no-dynamic-linker to ld with -E.
2017-04-20ELF/LD: Always consider STB_LOCAL symbols localMaciej W. Rozycki1-0/+5
Do not require forced local (STB_LOCAL) symbols to have a definition in a regular file to be considered to resolve local to the current module, matching `elf_link_renumber_local_hash_table_dynsyms'. In the absence of a regular definition any reference to a STB_LOCAL symbol will have to be garbage collected along with the undefined symbol itself, or the link will eventually fail. Either way the symbol concerned is not going to be external. bfd/ * elflink.c (_bfd_elf_symbol_refs_local_p): Always return TRUE if forced local.

2017-04-20Handle symbol defined in IR and referenced in DSOH.J. Lu1-0/+7
We need to make an IR symbol visible if it is defined in an IR object and referenced in a dynamic object. When --as-needed is used, since linker removes the IR symbol reference of the dynamic object if the dynamic object isn't needed in the first pass, the IR definition isn't visible to the dynamic object even if the dynamic object becomes needed in the second pass. Add dynamic_ref_after_ir_def to bfd_link_hash_entry to track IR symbol which is defined in an IR object and later referenced in a dynamic object. dynamic_ref_after_ir_def is preserved when restoring the symbol table for unneeded dynamic object. bfd/ PR ld/21382 * elflink.c (elf_link_add_object_symbols): Preserve dynamic_ref_after_ir_def when restoring the symbol table for unneeded dynamic object. include/ PR ld/21382 * bfdlink.h (bfd_link_hash_entry): Add dynamic_ref_after_ir_def. ld/ PR ld/21382 * plugin.c (is_visible_from_outside): Symbol may be visible from outside if dynamic_ref_after_ir_def is set.

-z nodynamic-undefined-weak is only implemented for x86. (The sparc backend has some support code but doesn't enable the option by including ld/emulparams/dynamic_undefined_weak.sh, and since the support looks like it may be broken I haven't enabled it.)

2017-04-03ld: Support ELF GNU program propertiesH.J. Lu1-0/+33
From .note.gnu.property section in each ELF input, we build a list of GNU properties if .note.gnu.property section isn't corrupt. The unknown properties are ignored. All property lists in relocatable inputs are merged into an output property list. When -z stack-size=N is used and N isn't 0, the GNU_PROPERTY_STACK_SIZE property will be merged with or added to the output property list. .note.gnu.property section is generated in output from the output property list. bfd/ * Makefile.am (BFD32_BACKENDS): Add elf-properties.lo.

2017-03-18DT_TEXTREL vs IFUNCAlan Modra1-0/+18
If you should somehow link non-pic objects into a PIE or shared library, resulting in an object with DT_TEXTREL (text relocations) set, and your executable or shared library also contains GNU indirect functions, then you're in trouble. To apply dynamic relocations ld.so will make the text segment writable. On most systems this will make the text segment non-executable, which will then result in a segfault when ld.so tries to run ifunc resolvers when applying relocations against ifuncs. This patch teaches PowerPC ld to detect the situation, and warn. * elf64-ppc.c (struct ppc_link_hash_table): Add local_ifunc_resolver and maybe_local_ifunc_resolver.

2017-02-28Nios2 dynobj handling fixesAlan Modra1-0/+24
A number of places in elf32-nios.c created dynamic sections but didn't set the hash table dynobj. That meant we could have duplicate dynamic sections connected to a number of bfds, so size_dynamic_sections didn't properly discard or allocate contents. Also, the entire set of dynamic sections was created in check_relocs on seeing GOT relocs, when only .got related sections are needed, probably done to hide segfaults later in finish_dynamic_sections. The patch fixes these issues and makes the assembler emit errors when nios2 lacks the necessary pc-relative relocs for subtraction expressions, rather than silently generating bad code. eg. ld-elf/merge. I've also tidied uses of elf32_nios2_hash_table and elf_hash_table. bfd/ PR 20995 * elf32-nios2.c (nios2_elf32_relocate_section): Use htab rather than elf32_nios2_hash_table or elf_hash_table.

2017-02-28PowerPC addpcis fixAlan Modra1-0/+13
This came up because I was looking at ld/tmpdir/addpcis.o and noticed the odd addends on REL16DX_HA. They ought to both be -4. The error crept in due REL16DX_HA howto being pc-relative (as indeed it should be), and code at gas/write.c:1001 after this comment /* Make it pc-relative. If the back-end code has not selected a pc-relative reloc, cancel the adjustment we do later on all pc-relative relocs. */ *not* cancelling the pc-relative adjustment. So I've made a dummy non-relative split reloc so that the generic code handles this, rather than attempting to add hacks later in md_apply_fix which would not be very robust. Having the new internal reloc also makes it easy to support addpcis rx,sym@ha as an equivalent to addpcis rx,(sym-0f)@ha 0: The patch also fixes overflow checking, which must test whether the addi will overflow too since @l relocs don't have any overflow check. Lastly, since I was poking at md_apply_fix, I arranged to have the generic gas/write.c code emit errors for subtraction expressions where we lack reloc support. include/ * elf/ppc64.h (R_PPC64_16DX_HA): New.
