* Check elf_strptr didn't fail getting section name.Mark Wielaard2014-11-172-2/+6
| | | | | | | | Since elf_strptr can fail and return NULL we should always check the result before usage. Debug sections are only handled by section name, so make sure the name actually exists. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* libebl: Add ebl_func_addr_mask plus ARM backend implementation.Mark Wielaard2014-06-225-4/+34
| | | | | | | | | | | | | | The ARM EABI says that the zero bit of function symbol st_value indicates whether the symbol points to a THUMB or ARM function. Also the return value address in an unwind will contain the same extra bit to indicate whether to return to a regular ARM or THUMB function. Add a new ebl function to mask off such bits and turn a function value into a function address so that we get the actual value that a function symbol or return address points to. It isn't easily possible to reuse the existing ebl_resolve_sym_value for this purpose, so we end up with another hook that can be used from dwfl_module_getsym, handle_cfi and elflint.

* backends: Add ebl_check_reloc_target_type.Mark Wielaard2014-05-196-3/+74
| | | | | | | | | And implement for arm and ia64. Both have special section types that are valid targets for a reloc. Both refer to unwind data. elflint now just calls ebl_check_reloc_target_type instead of hard coding the expected section types. Signed-off-by: Mark Wielaard <mjw@redhat.com>
* libdwfl: Introduce dwfl_module_getsym_info and dwfl_module_addrinfo.Mark Wielaard2013-12-206-1/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some arches like ppc64 use function descriptor values instead of function addresses causing matching of names and addresses to fail when using dwfl_module_getsym or dwfl_module_addrsym. Add ebl hook to resolve any function descriptor values found in non-ET_REL modules. The new function dwfl_module_getsym_info doesn't adjust the symbol value in any way, but returns the adjusted and/or resolved address associated with the symbol separately. The new function dwfl_module_addrinfo resolves against both the address associated with the symbol (which could be the function entry address) value and the adjusted st_value. So that it is easy to resolve and match either function descriptors and/or function entry addresses. Since these new functions also return more information they replace the dwfl_module_getsym_elf and dwfl_module_addrsym_elf functions that never made it into a released elfutils version. addr2line and readelf now use the new functions when looking up functions names. addr2line will now also display the section the address was found in when given -x. Extra testcases were added for both addr2line and the dwflsyms testscase. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* backends: ppc_abi_cfi reg1 use DW_CFA_val_offset not DW_CFA_val_expression.Mark Wielaard2013-10-072-0/+10
| | | | | | | | | | | | | | | Register rules using expressions are stored using an offset from the start of the .eh_frame or .debug_frame ELF section data. Since abi_cfi rules aren't stored in those ELF sections they should use neither DW_CFA_expression nor DW_CFA_val_expression. The only backend that used DW_CFA_val_expression was ppc_cfi.c. It was easier to express the same rule using DW_CFA_val_offset than to change the code to handle register rules using expressions. On most architectures this did work by accident. See the definition of struct dwarf_frame_register value in libdw/cfi.h to see why. But on ia64 the abi_cfi data and actual frame data were placed too far apart and caused a crash in tests/run-addrcfi.sh for ppc32. Signed-off-by: Mark Wielaard <mjw@redhat.com>
