* libdw: Make sure Ebl is always freed from cfi frame cache.Mark Wielaard2015-11-271-4/+19
| | | | | | | | | | | | | | libdwfl sets the Dwfl_Module Ebl for the eh_cfi and dwarf_cfi cache to save a bit of memory. It also calls ebl_closebackend on the ebl to free it. The Dwarf_CFI never frees the Ebl in the cache, even when it opened one itself. This means that if only libdw calls are used to access the Dwarf_CFI the Ebl might be leaked. Always destroy the Dwarf_CFI cache Ebl in __libdw_destroy_frame_cache. And in __libdwfl_module_free clear the Dwarf_CFI Ebl if it is the Dwfl_Module Ebl before calling dwarf_cfi_end and dwarf_end.

* Move nested functions in dwfl_module.cChih-Hung Hsieh2015-11-031-16/+17
| | | | | | | | * Nested functions in this file are moved to file scope to compile with clang. Extra parameters are added to pass local variables. Signed-off-by: Chih-Hung Hsieh <[email protected]>
* libdwfl: Move dwz alt multi file searching to find_debuginfo callback.Mark Wielaard2014-05-021-2/+12
| | | | | | | | | | Don't hard code the Dwarf dwz alt multi file search but allow the user to override it through the standard Dwfl_Callbacks. Also move ownership completely to the user of dwarf_setalt by removing free_alt from Dwarf and adding alt, fd and elf fields to Dwfl_Module. Add a relative .dwz file test case.

* libdwfl: Fix various frame related memory leaks.Mark Wielaard2013-12-161-0/+6
| | | | | | | | | | The result of dwarf_cfi_addrframe should have been freed when done. Dwfl_Module cached the reloc_info and the eh_cfi it which also should have been released when disposing of the module.

* libdwfl: Add minisymtab support.Mark Wielaard2013-01-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an auxiliary symbol table dwfl_file aux_sym to Dwfl_Module if all we have is the dynsym table. The main file might contain a .gnu_debugdata section. The .gnu_debugdata section is a compressed embedded ELF file that contains the text (code) section symbols from the symtab table that are not in the main file dynsym table. dwfl_module_getsymtab (), dwfl_module_addrsym () and dwfl_module_getsym () will use the auxiliary symbol table when available (and no full symtab is available from the debug file). * libdwflP.h (struct Dwfl_Module): Add aux_sym, aux_symdata, aux_syments, aux_symstrdata, aux_symxndxdata and aux_first_global. (dwfl_adjusted_aux_sym_addr): New function. (dwfl_deadjust_aux_sym_addr): Likewise. (dwfl_adjusted_st_value): Take and check symfile argument. (dwfl_deadjust_st_value): Likewise. * dwfl_module_getdwarf.c (find_prelink_address_sync): Take and use dwfl_file as argument to set address_sync. (find_debuginfo): Call find_prelink_address_sync with debug file. (find_aux_sym): New function. (find_symtab): Use find_aux_sym if all we have is the dynsym table and fill in aux DwflModule fields. (dwfl_module_getsymtab): Return syments plus aux_syments. (load_symtab): Always set first_global. * dwfl_module_addrsym.c (dwfl_module_addrsym): Check symfile when using same_section. Calculate first_global based on both mod->first_global and mod->aux_first_global. * dwfl_module.c (__libdwfl_module_free): Free aux_sym. * dwfl_module_getsym.c (dwfl_module_getsym): Use auxsym table to retrieve symbol and name if necessary, making sure all locals from any table come before any globals. * dwfl_module_info.c (dwfl_module_info): Call dwfl_adjusted_st_value with symfile. * relocate.c (resolve_symbol): Likewise. https://fedoraproject.org/wiki/Features/MiniDebugInfo Signed-off-by: Mark Wielaard <[email protected]>

Except some very small files (<5 lines) which didn't have any headers at all before, the linker .maps files and the libcpu/defs files which only contain data and libelf/elf.h which comes from glibc and is under LGPLv2+. config: - elfutils.spec.in: Add new License: headers and new %doc files. - Update all license headers to GPLv2/LGPLv3+ for files used by libs. src, tests: - All files updated to GPLv3+. Except for the test bz2 data files, the linker maps and script files and some very small files (<5 lines) that don't have any headers.
