2016-12-26dynrelro section for read-only dynamic symbols copied into executableAlan Modra1-7/+21
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.

2016-12-14ld: aarch64: fix TLS relaxation where TCB_SIZE is usedYury Norov1-5/+15
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for ilp32. During relaxation, ld goes to do a replace: bl __tls_get_addr => add R0, R0, TCB_SIZE But actual implementation is: bfd_putl32 (0x91004000, contents + rel->r_offset + 4); Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32. The possible fix for it is: bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4); But ilp32 also needs w-registers, so it's simpler to put proper instruction in #if/#else condition. There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new tests added for ilp32 mode to test it.

2016-10-07Pass link_info to _bfd_merge_private_bfd_dataAlan Modra1-2/+3
Most BFD linker functions take a bfd_link_info param, which reinforces the fact that they are linker functions and allow access to linker callbacks, eg. einfo for printing errors. I was going to use einfo for --fatal-warnings support before I decided a better way was the patch commit 4519d071. bfd/ * targets.c (bfd_target <_bfd_merge_private_bfd_data>): Replace obfd param with struct bfd_link_info param.

If a backend supports it, PLT entry isn't needed when all references to a STT_GNU_IFUNC symbols are done via GOT or static function pointers.

2016-05-28Return void from linker callbacksAlan Modra1-19/+11
The ldmain.c implementation of these linker callback functions always return true, so any code handling a false return is dead. What's more, some of the bfd backends abort if ever a false return is seen, and there seems to be some confusion in gdb's compile-object-load.c. The return value was never meant to be "oh yes, a multiple_definition error occurred", but rather "out of memory or other catastrophic failure". This patch removes the status return on the callbacks that always return true. I kept the return status for "notice" because that one does happen to need to return "out of memory". include/ * bfdlink.h (struct bfd_link_callbacks): Update comments.

2016-05-03[AArch64] Also puts value in place for R_AARCH64_RELATIVEJiong Wang1-1/+7
When handling absolute relocations for global symbols bind within the shared object, AArch64 will generate one dynamic RELATIVE relocation, but won't apply the value for this absolution relocations at static linking stage. This is different from AArch64 gold linker and x86-64. This is not a bug as AArch64 is RELA, there is only guarantee that relocation addend is placed in the relocation entry. But some system softwares originally writen for x86-64 might assume AArch64 bfd linker gets the same behavior as x86-64, then they could take advantage of this buy skipping those RELATIVE dynamic relocations if the load address is the same as the static linking address. This patch makes AArch64 BFD linker applies absolution relocations at static linking stage for scenario described above. Meanwhile old AArch64 android loader has a bug (PR19163) which relies on current linker behavior as a workaround, so the same option --no-apply-dynamic-relocs added.

2016-01-21[AArch64] Relax long branch veneer insertion for non STT_FUNC symbolJiong Wang1-6/+19
As defined at AArch64 ELF Specification (4.6.7 Call and Jump relocations), symbol with type of non STT_FUNC but in different input section with relocation place should insert long branch veneer also. Meanwhile the current long branch veneer infrastructure havn't considered the situation where the branch destination is "sym_value + rela->addend". This was OK because we only insert veneer for long call destination is STT_FUNC symbol for which the addend is always zero. But as we relax the support to other situations by this patch, we need to handle addend be non-zero value. For example, for static function, relocation against "local symbol" are turned into relocation against "section symbol + offset" where there is a valid addend. bfd/ * elfnn-aarch64.c (aarch64_type_of_stub): Allow insert long branch veneer for sym_sec != input_sec.
