* libdwfl: Fix and test aux_sym address_sync with relocated ELFJosh Stone2013-11-187-14/+54
| | | | | | | | | | The aux_sym address_sync already worked with a full prelink, which has .gnu.prelink_undo, but it failed on plain relocations with prelink -r. Now it uses the difference in ehdr.e_entry as a first offset guess, and the tests confirm this seems to work fine. Signed-off-by: Josh Stone <jistone@redhat.com>

| | | | | | | | | | | The two test files that contains minisymtab tables and the expected test output were wrongly generated. Also prelink tests were missing to check that a prelinked main ELF file with separate debug or minisyms generated correctly adjusted symbol values. The dwflsyms test was also extended to check print and check the result of dwfl_module_relocate_address. Reported-by: Josh Stone <jistone@redhat.com> Signed-off-by: Mark Wielaard <mjw@redhat.com>

* libelf: Only memcpy ehdr back when not already directly mmapped.Mark Wielaard2013-11-112-1/+6
| | | | | | | | | | When the elf file is mmapped ehdr can still point to ehdr_mem if the address is unaligned. In such cases we do need to memcpy the ehdr back to the file. We shouldn't when ehdr already comes directly from the mmapped file, because that would cause an memcpy call with overlapping addresses (ehdr being copied directly over itself).

* Fix some (harmless) cppcheck warnings.Mark Wielaard2013-11-095-10/+24
| | | | | | | | | | | | | | | | | | | | | | | | | [dwarf_getaranges.c:149]: (warning) Ineffective statement similar to '*A++;'. Did you intend to write '(*A)++;'? There was already an XXX statement that we weren't using the result. Explicitly read the segment_size and check it is zero. And report an error if it isn't, since we aren't prepared to handle such a case. [arlib.c:62]: (error) Uninitialized variable: tmpbuf [arlib.c:124]: (error) Uninitialized variable: tmpbuf cppcheck is wrong. tmpbuf is initialized in the snprintf call whose result is use in the same memcpy call. It does make the code less readable and harder to understand. So explicitly split the snprintf and memcpy calls. [nm.c:766]: (warning) Assert statement modifies 'cnt'. The cnt variable was only used for this assert sanity check. But it is bad style to do have side effects inside an assert statement. Increase cnt after the assert.

* README: Document that tools and libraries should be upgraded together.Mark Wielaard2013-11-041-0/+7
| | | | | | | | | | On some distributions it was possible to upgrade separate parts of elfutils individually. That causes hard to debug issues since some tools (e.g. readelf) and some libraries (e.g. libdw) depend on libelf internal data structures, which could be different between versions (or when configured with different flags). So explicitly document that they should always be upgraded together. Signed-off-by: Mark Wielaard <mjw@redhat.com>

* backends: ppc_abi_cfi reg1 use DW_CFA_val_offset not DW_CFA_val_expression.Mark Wielaard2013-10-078-3/+32
| | | | | | | | | | | | | | | 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>
* libdw: Make sure that every debug_types sig8 is hashedJosh Stone2013-10-037-2/+111
| | | | | | | | | | | | When dwarf_formref_die can't find a sig8 in the hash, it walks __libdw_intern_next_unit, and was then adding those to the hash. However, if dwarf_offdie_types is called earlier, which also uses that next_unit, then they are missed from the hash (and never revisited). This patch makes __libdw_intern_next_unit do the sig8 hash insert, so no type unit is ever missed. Signed-off-by: Josh Stone <jistone@redhat.com>
