2018-12-28PR24015, glibc-2.28 on little-endian mips32 brokenAlan Modra1-0/+8
Commit 2bf2bf23da exposed a bug on targets that create common sections other than the standard ELF SHN_COMMON. If these are output by ld -r, then their type becomes SHT_PROGBITS unless the target handles them specially (eg. by elf_backend_special_sections), and if they are merged into .bss/.sbss by ld -r then that section becomes SHT_PROGBITS. Worse, if they are output by ld -r, then their size is increased by bfd_generic_define_common_symbol during final link, which leads to bogus file contents being copied to output. For mips, it seems to me that the .scommon section should not be output for ld -r, but I haven't made that change in this patch.

2018-12-14elf: Add PT_GNU_PROPERTY segment typeH.J. Lu1-0/+10
Linkers group input note sections with the same name into one output note section with the same name. One output note section is placed in one PT_NOTE segment. New linkers merge all input .note.gnu.property sections into one output .note.gnu.property section with a single NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older linkers treat input .note.gnu.property section as a generic note section and just concatenate all input .note.gnu.property sections into one output .note.gnu.property section without merging them, we may see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which are invalid. GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such that linker sets the bit for non-relocatable outputs. But it isn't sufficient: 1. It doesn't cover generic properties. 2. When -mx86-used-note=yes is passed to x86 assembler, the GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED property in object file and older linkers generate invalid NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit set. I am proposing the following changes: 1. Add PT_GNU_PROPERTY segment type: # define PT_GNU_PROPERTY (PT_LOOS + 0x474e553) which covers .note.gnu.property section. 2. Remove GNU_PROPERTY_X86_UINT32_VALID. bfd/ PR ld/23900 * elf.c (get_program_header_size): Add a PT_GNU_PROPERTY segment for NOTE_GNU_PROPERTY_SECTION_NAME.

2018-12-06PowerPC @l, @h and @ha warnings, plus VLE e_liAlan Modra1-0/+7
This patch started off just adding the warnings in tc-ppc.c about incorrect usage of @l, @h and @ha in instructions that don't have 16-bit D-form fields. That unfortunately showed up three warnings in ld/testsuite/ld-powerpc/vle-multiseg.s on instructions like e_li r3, IV_table@l+0x00 which was being assembled to 8: 70 60 00 00 e_li r3,0 a: R_PPC_ADDR16_LO IV_table The ADDR16_LO reloc is of course completely bogus on e_li, which has a split 20-bit signed integer field in bits 0x1f7fff, the low 11 bit in 0x7ff, the next 5 bits in 0x1f0000, and the high 4 bits in 0x7800. Applying an ADDR16_LO reloc to the instruction potentially changes the e_li instruction to e_add2i., e_add2is, e_cmp16i, e_mull2i, e_cmpl16i, e_cmph16i, e_cmphl16i, e_or2i, e_and2i., e_or2is, e_lis, e_and2is, or some invalid encodings. Now there is a relocation that suits e_li, R_PPC_VLE_ADDR20, which was added 2017-09-05 but I can't see code in gas to generate the relocation. In any case, VLE_ADDR20 probably doesn't have the correct semantics for @l since ideally you'd want an @l to pair with @h or @ha to generate a 32-bit constant. Thus @l should only produce a 16-bit value, I think. So we need some more relocations to handle e_li it seems, or as I do in this patch, modify the behaviour of existing relocations when applied to e_li instructions. include/ * opcode/ppc.h (E_OPCODE_MASK, E_LI_MASK, E_LI_INSN): Define. bfd/ * elf32-ppc.c (ppc_elf_howto_raw <R_PPC_VLE_ADDR20>): Correct mask and shift value.

2018-12-05[aarch64] Add support for pointer authentication B keySam Tebbs1-0/+4
Armv8.3-A has another key used in pointer authentication called the B-key (other than the A-key that is already supported). In order for stack unwinders to work it is necessary to be able to identify frames that have been signed with the B-key rather than the A-key and it was felt that keeping this as an augmentation character in the CIE was the best bet. The DWARF extensions for ARM therefore propose to add a new augmentation character 'B' to the CIE augmentation string and the corresponding cfi directive ".cfi_b_key_frame". I've made the relevant changes to GAS and LD to add support for B-key unwinding, which required modifying LD to check for 'B' in the augmentation string, adding the ".cfi_b_key_frame" directive to GAS and adding a "pauth_key" field to GAS's fde_entry and cie_entry structs. The pointer authentication instructions will behave as NOPs on architectures that don't support them, and so a check for the architecture being assembled for is not necessary since there will be no behavioural difference between augmentation strings with and without the 'B' character on such architectures. 2018-12-05 Sam Tebbs <sam.tebbs@arm.com> bfd/ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Add check for 'B'. gas/ * dw2gencfi.c (struct cie_entry): Add tc_cie_entry_extras invocation.

2018-11-27[ARM] Update knowledge of bfd architecturesThomas Preud'homme1-0/+8
Commit c0c468d562649df0f695737262b6230b7a56a4bb updated bfd's knowledge of Arm architectures to Armv5TEJ and later but missed the list of CPUs recognized by objdump -d -m<cpu>. .note.gnu.arm.ident related code is intentionally not updated as build attributes are a better mechanism to express the ISA in a file. However this patch adds tests for the existing code since no existing testcase cover those codepaths. Since I've only ever managed for bfd_arm_get_mach_from_notes () to have an effect by using objcopy on a file with a note but no Arm build attribute, the tests make use of both objcopy actions supported by run_dump_test which requires to have a ld line as well. Note that the CPU list in bfd/cpu-arm.c was simply copied over from GAS' CPU list but sorted alphabetically as already done for existing entries. 2018-11-27 Thomas Preud'homme <thomas.preudhomme@linaro.org> bfd/ * cpu-arm.c (processors): Add processors known to GAS but missing here and reindent.

2018-11-27MIPS/LD: Accept high-part relocations in PIC code with absolute symbolsMaciej W. Rozycki1-0/+7
Accept R_MIPS_HI16, R_MIPS_HIGHER and R_MIPS_HIGHEST relocations and their compressed counterparts in PIC code where the symbol referred is absolute. Such an operation is meaningful, because an absolute symbol effectively is a constant the calculation of the value of which has been deferred to the static link time, and which is not going to change any further at the dynamic load time. Therefore there is no need ever to refuse the use of these relocations with such symbols, as the resulting run-time value observed by the program will be correct even in PIC code. This is not the case with R_MIPS_26 and its compressed counterparts, because the run-time value calculated by the instructions these relocations are used with depends on the address of the instruction itself, and that can change according to the base address used by the dynamic loader. Therefore these relocations have to continue being rejected in PIC code even with absolute symbols. This allows successful linking of code that relies on previous linker behavior up to commit 861fb55ab50a ("Defer allocation of R_MIPS_REL32 GOT slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>, which introduced the problematic check missing this special exception for absolute symbols. bfd/ * elfxx-mips.c (_bfd_mips_elf_check_relocs) <R_MIPS16_HI16> <R_MIPS_HI16, R_MIPS_HIGHER, R_MIPS_HIGHEST, R_MICROMIPS_HI16> <R_MICROMIPS_HIGHER, R_MICROMIPS_HIGHEST>: Also accept an absolute symbol in PIC code. ld/ * testsuite/ld-mips-elf/pic-reloc-0.d: New test. * testsuite/ld-mips-elf/pic-reloc-1.d: New test. * testsuite/ld-mips-elf/pic-reloc-2.d: New test. * testsuite/ld-mips-elf/pic-reloc-3.d: New test. * testsuite/ld-mips-elf/pic-reloc-4.d: New test. * testsuite/ld-mips-elf/pic-reloc-absolute-hi.ld: New test linker script. * testsuite/ld-mips-elf/pic-reloc-absolute-lo.ld: New test linker script. * testsuite/ld-mips-elf/pic-reloc-ordinary.ld: New test linker script. * testsuite/ld-mips-elf/pic-reloc-j.s: New test source. * testsuite/ld-mips-elf/pic-reloc-lui.s: New test source. * testsuite/ld-mips-elf/mips-elf.exp: Run the new tests.
2018-11-27MIPS/LD: Continue processing with refused relocations in PIC codeMaciej W. Rozycki1-0/+8
Switch from `_bfd_error_handler' to `info->callbacks->einfo' with error reporting concerning the use of position-dependent relocations such as R_MIPS_HI16 or R_MIPS_26 in PIC code and continue processing so that any subsequent link errors are also shown rather than the linker terminating right away. This can reduce user frustration where correcting one error only reveals another one; instead all are shown together making them all possible to investigate at once. The use of the `%X' specifier causes the linker to terminate unsuccessfully at the end of processing. Also fix the message to say `cannot' rather than `can not'. bfd/ * elfxx-mips.c (_bfd_mips_elf_check_relocs) <R_MIPS16_26> <R_MIPS_26, R_MICROMIPS_26_S1>: Use `info->callbacks->einfo' rather than `_bfd_error_handler' to report refused relocations in PIC code and continue processing.

2018-11-27AArch64: Fix regression in Cortex A53 erratum when PIE. (PR ld/23904)Tamar Christina1-0/+12
The fix for PR ld/22263 causes TLS relocations using ADRP to be relaxed into MOVZ, however this causes issues for the erratum code. The erratum code scans the input sections looking for ADRP instructions and notes their location in the stream. It then later tries to find them again in order to generate the linker stubs. Due to the relaxation it instead finds a MOVZ and hard aborts. Since this relaxation is a valid one, and in which case the erratum no longer applies, it shouldn't abort but instead just continue. This changes the TLS relaxation code such that when it finds an ADRP and it relaxes it, it removes the erratum entry from the work list by changing the stub type into none so the stub is ignored. The entry is not actually removed as removal is a more expensive operation and we have already allocated the memory anyway. The clearing is done for IE->LE and GD->LE relaxations, and a testcase is added for the IE case. The GD case I believe to be impossible to get together with the erratum sequence due to the required BL which would break the sequence. However to cover all basis I have added the guard there as well. build on native hardware and regtested on aarch64-none-elf, aarch64-none-elf (32 bit host), aarch64-none-linux-gnu, aarch64-none-linux-gnu (32 bit host) Cross-compiled and regtested on aarch64-none-linux-gnu, aarch64_be-none-linux-gnu Testcase in PR23940 tested and works as expected now and benchmarks ran on A53 showing no regressions and no issues. bfd/ChangeLog: PR ld/23904 * elfnn-aarch64.c (_bfd_aarch64_adrp_p): Use existing constants.

2018-11-02PR23850, strip should not discard/move .rela.plt in executableAlan Modra1-0/+6
strip/objcopy can't deal with alloc reloc sections, not .rela.dyn or .rela.plt in a dynamic executable, or .rela.plt/.rela.iplt in a static executable. So, don't have BFD treat them as side-channel data associated with the section they are relocating. PR 23850 * elf.c (bfd_section_from_shdr): Treat SHF_ALLOC SHT_REL* sections in an executable or shared library as normal sections.
2018-10-31Don't create got section while processing TLS Local Exec relocations.Renlin Li1-0/+5
For Local Exec TLS model, the offset of the variable from the thread pointer can be computed at static link time. This doesn't require GOT indirection. The initial change is a bad fix for a problem during TLS GD -> LE relaxation. The proper fix is to check whether _GLOBAL_OFFSET_TABLE_ is referenced, create got section if yes. And the fix is already in the repository. bfd/ 2018-10-31 Renlin Li <renlin.li@arm.com> * elfnn-aarch64.c (elfNN_aarch64_check_relocs): Don't create got section for Local Exec TLS model.
