* backends: Add frame pointer unwinding for LoongArchYouling Tang2023-05-091-0/+6
| | | | | | | | | | | If we don't find any debug information for a given frame, we usually cannot unwind any further. However, the binary in question might have been compiled with frame pointers, in which case we can look up the well known frame pointer locations in the stack snapshot and use them to bridge the frames without debug information.

* backends: Handle DW_TAG_unspecified_type in dwarf_peeled_die_typeMark Wielaard2023-02-141-0/+5
| | | | | | | | | | | | | | | | binutils 2.40 introduces DW_TAG_unspecified_type for assembly functions with an unknown return type. This breaks the run-funcretval.sh testcase because dwfl_module_return_value_location returns an error for such functions because it cannot determine the return value location. Fix that by treating DW_TAG_unspecified_type as if the DIE doesn't have a DW_AT_type. Also update the testcase to explicitly checking for DW_TAG_unspecified_type and printing "returns unspecified type". https://sourceware.org/bugzilla/show_bug.cgi?id=30047 Signed-off-by: Mark Wielaard <[email protected]>
* backends: sparc uses NONE relocation type in ET_EXEC and ET_DYN filesMark Wielaard2023-01-191-0/+4
| | | | | | | | | Using the NONE relocation doesn't do anything, but is harmless. This fixes several (self) tests on sparc that use elflint to check files are valid ELF. Signed-off-by: Mark Wielaard <[email protected]>

* Arm Ehdr flag printingUlrich Drepper2022-06-061-0/+6
| | | | | | | | | | | | | | | | | | Arm needs to decode flags and I modeled it after the binutils code. The same messages are printed. Given the requirement of the interface and the ABIs the current version of the callback function isn't sufficient unless one wants to create a stateful interface. The problem is that most flags need to be interpreted in the context of the ABI version. So I changed the API to also pass the original flag value. This shouldn't be a problem because there are no users yet. There is also a bug in ebl_machine_flag_name. When copying the string provided by the callback cp is moved past the NUL byte. It should move to the NUL byte. Otherwise one cannot anything but the first added flag description. Finally some cosmetic changes (space after each comma in the output).

* backends: Use PTRACE_GETREGSET for ppc_set_initial_registers_tidMark Wielaard2022-02-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in ppc_initreg.c used PTRACE_PEEKUSER to fetch all registers one by one. Which is slightly inefficient. It did this because it wanted things to work on linux 2.6.18 which didn't support PTRACE_GETREGSET. PTRACE_GETREGSET was only officially since 2.6.34 (but backported to some earlier versions). It seems ok to require a linux kernel that supports PTRACE_GETREGSET now. This is much more efficient since it takes just one ptrace call instead of 44 calls to fetch each register individually. For some really old versions we need to include <linux/ptrace.h> to get PTRACE_GETREGSET defined. And on ppc64 there is no 32bit version of struct pt_regs available, so we define that ourselves and check how much data is returned to know whether this is a full pt_regs or one for a 32bit process. An alternative would be to use the raw iov_base bytes with 64bit or 32bit offset constants to get at the registers instead of using a struct with names. The code works for inspecting a 32bit process from a 64bit build, but not the other way around (the previous code also didn't). This could work if we also defined and used a 64bit pt_regs struct on ppc32. But it seems a use case that is not really used (it was hard enough finding ppc32 setups to test this on). Tested against ppc and ppc64 on linux 2.6.32 and glibc 2.12 and ppc and ppc64 on linux 3.10.0 with glibc 2.17. Signed-off-by: Mark Wielaard <[email protected]>
* RISC-V: PR27925 Add support for LP64 and LP64F ABIs return valuesWilliam Cohen2021-09-301-0/+13
| | | | | | | | | | | | The RISC-V Linux kernel is compiled without floating point (the LP64 ABI) and elfutils could not obtain return value locations for functions in the kernel. This issue was noticed when Systemtap generated RISC-V kernel modules for scripts that used $return target variables in function return probes. This patch adds the needed support to provide return value information for the LP64 and LP64F ABIs. Signed-off-by: William Cohen <[email protected]>

| | | | | | | | | The x86_64 abi defines a special section type for .eh_frame[_hdr], SHT_X86_64_UNWIND, which is a valid relocation target type. https://sourceware.org/bugzilla/show_bug.cgi?id=26878 Signed-off-by: Mark Wielaard <[email protected]>
* backends: Remove tilegx backend.Mark Wielaard2020-10-261-0/+12

* libebl: Remove unused ebl_syscall_abi.Mark Wielaard2020-10-261-0/+12
| | | | | | | | | GCC11 -Warray-parameter warned about ebl_syscall_abi being inconsistently declared (once with a pointer to int, once with an array of 6 int elements). Since ebl_syscall_abi isn't actually used and was only implemented for 3 backends without any tests just remove it. Signed-off-by: Mark Wielaard <[email protected]>

* backends: Make the reloc_nametable zero element an one char array.Mark Wielaard2020-06-191-0/+6
| | | | | | | | We are using the reloc_nametable zero element as an char array. So make that element an actual array (we are actually after one of the next string arrays in the table). Signed-off-by: Mark Wielaard <[email protected]>
* libebl: Remove Ebl struct size check and MODVERSION string.Mark Wielaard2020-06-101-0/+20
| | | | | | | | | | | | | | | | We used to do several sanity checks when the ebl backend libraries were loaded to make sure there was no version mismatch. When initializing the backend we passed the current Ebl struct size so the library could check it supported the given Ebl struct and we checked that the init method returned the correct build time module version string. Neither are necessary now that the backends are builtin. Remove both the struct size check and the MODVERSION string (which wasn't actually checked anymore). Make the init function return the given Ebl handle or NULL on error (no init function currently indicates any error). Signed-off-by: Mark Wielaard <[email protected]>
* Don't use dlopen() for libebl modulesOmar Sandoval2019-08-291-0/+1
| | | | | | | | | | | | Currently, architecture-specific code for libebl exists in separate libebl_$ARCH.so libraries which libebl loads with dlopen() at runtime. This makes it impossible to have standalone, statically-linked binaries which use libdwfl if they depend on any architecture-specific functionality. Additionally, when these libraries cannot be found, the failure modes are non-obvious. So, let's get rid of libebl_$arch.so and move it all into libdw.so/libdw.a, which simplifies things considerably. Signed-off-by: Omar Sandoval <[email protected]>
* Add PIC and non-PIC variants of libcpu and libeblOmar Sandoval2019-08-281-0/+1
| | | | | | | | | Currently, libcpu and libebl are always compiled as PIC. An upcoming change will add the objects from libcpu.a and libebl.a to libdw.a, which should not be PIC unless configured that way. So, make libcpu.a and libebl.a non-PIC and add libcpu_pic.a and libebl_pic.a. Signed-off-by: Omar Sandoval <[email protected]>
* libcpu: merge libcpu_{i386,x86_64,bpf} into one libraryOmar Sandoval2019-08-281-0/+4

* libdwelf: Add dwelf_elf_e_machine_string and use it in readelf.Mark Wielaard2019-07-101-0/+18
| | | | | | | | | | | | | | | | To print eh human readable description of the ELF e_machine header field we used the ebl name. But this is not set for most EM constants. Introduce a new function dwelf_elf_e_machine_string that does work for all known EM values. Use that in eu-readelf to print a string representation of the e_machine value. Since this was the only usage of ebl->name, remove that from struct ebl. Also add a testcase that makes sure dwelf_elf_e_machine_string works for all EM values in the libelf/elf.h header so we will immediately notice when a new value appears.

| | | | | | | | | | The _GLOBAL_OFFSET_TABLE_ symbol might point to the DT_PLTGOT, which is in the .got section, even if the symbol itself is associated with the .got.plt section.

* RISC-V: Add untested 32-bit core file support.Jim Wilson2019-01-131-0/+11
| | | | | | | | Adds 32-bit support exactly the same way that the sparc backend handles 32- and 64-bit core file support. The 64-bit core file support was tested and still works same as before. Signed-off-by: Jim Wilson <[email protected]>
* RISC-V: Add initial return value location support.Jim Wilson2019-01-101-0/+8
| | | | | | | | | | Started with the aarch64 support and modified it for RISC-V. The flattened structure support hasn't been written yet, but the rest of it should be correct for the LP64D ABI. We have potentially 6 different ABIs to support, so this requires checking elf header flags in riscv_init when setting the hook. Signed-off-by: Jim Wilson <[email protected]>
* RISC-V: Improve riscv64 core file support.Jim Wilson2019-01-081-0/+5
| | | | | | | | | This fixes two problems. The offset for x1 is changed from 1 to 8 because this is a byte offset not a register skip count. Support for reading the PC value is added. This requires changing the testsuite to match the new readelf output for coredumps. Signed-off-by: Jim Wilson <[email protected]>
* backends: Add x86_64 section_type_name for SHT_X86_64_UNWIND.Mark Wielaard2018-11-091-0/+5

* backends: ppc use define instead of const for size of dwarf_regs array.Mark Wielaard2018-10-201-0/+5
| | | | | | | | | The size of the dwarf_regs is a constant, but when building without optimizations the compiler doesn't see that and will warn that it cannot proof the stack size is bounded. Use a define instead of a const, so the compiler will use a constant expression everywhere. Signed-off-by: Mark Wielaard <[email protected]>

* backends: Use elf_getshdrstrndx to find .odp section in ppc64_initMark Wielaard2018-09-131-0/+4
| | | | | | | | | The .odp section is found by name. But ppc64_init used the e_shstrndx Ehdr field for that. This is wrong if the file contains more than SHN_LORESERVE sections. Use elf_getshdrstrndx instead to find the shstrtab section. Signed-off-by: Mark Wielaard <[email protected]>
* backends: Always use elf_getshdrstrndx in check_special_symbol.Mark Wielaard2018-09-131-0/+10
| | | | | | | | | | The check_special_symbol backend functions used the Ehdr e_shstrndx field to get at the name of sections. This is not correct if there are more than SHN_LORESERVE sections. Always use elf_getshdrstrndx to get the shstrtab section. And drop the Ehdr argument that isn't necessary anymore. Signed-off-by: Mark Wielaard <[email protected]>

* backends,bpf: add proper relocation supportYonghong Song2018-06-211-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to libdw does not have proper BPF relocation support, the pahole cannot display filenames correctly for objects with default llvm options. So we have to invent a special option "llc -march=bpf -mattr=dwarfris" to prevent llvm from generating cross-section dwarf relocation records (https://reviews.llvm.org/rL326505). The pahole related discussion is in linux netdev mailing list (http://lists.openwall.net/netdev/2018/06/15/38, etc.) We would like to add proper BPF relocation support to libdw so eventually we could retire the special llc bpf flag "-mattr=dwarfris". The bpf relocations are defined in llvm_repo:include/llvm/BinaryFormat/ELFRelocs/BPF.def: ELF_RELOC(R_BPF_NONE, 0) ELF_RELOC(R_BPF_64_64, 1) ELF_RELOC(R_BPF_64_32, 10) Removed the relocation type R_BPF_MAP_FD whoes name does not confirm to llvm definition and replaced it with R_BPF_64_64. The BPF object is just a relocatible object, not an executable or a shared library, so assign ELF type to REL only in bpf_reloc.def. Signed-off-by: Yonghong Song <[email protected]>

* aarch64: Add default cfi rule to restore SP from CFA address.Mark Wielaard2018-04-131-0/+5
| | | | | | | | | The CFA is set by default to the stack pointer of the previous frame. So that is also how we can always restore the SP. This default aarch64 CFI rule is necessary on Fedora 28 with GCC8 to make the run-deleted.sh and run-backtrace-dwarf.sh testcases work. Signed-off-by: Mark Wielaard <[email protected]>
* Include sys/ptrace.h as early as possible.Mark Wielaard2018-02-151-0/+4
| | | | | | | | | | | | | | | | | | | On some systems, at least on Fedora 27 ppc64le with glibc 2.26-24 and kernel 4.14.18-300, including sys/ptrace.h late (after signal.h or sys/wait.h for example) will cause issues and produce errors like: In file included from /usr/include/asm/sigcontext.h:12:0, from /usr/include/bits/sigcontext.h:30, from /usr/include/signal.h:287, from /usr/include/sys/wait.h:36, from linux-pid-attach.c:38: /usr/include/sys/ptrace.h:73:3: error: expected identifier before numeric constant PTRACE_GETREGS = 12, ^ Swapping the include order fixes these issues.
