* libdw: Cache ELF directory early. Explicitly set it in dwfl.Mark Wielaard2018-05-201-0/+1
| | | | | | | | | | | The logic that finds alt files and dwo files relies on having an open file descriptor. But after all needed ELF data has been read the underlying Elf file descriptor can be closed. libdwfl in particular closes file descriptor fairly aggressively. So capture the directory early on. And make dwfl set it if it has recorded it. Which it will do now before closing a file descriptor for the main Dwfl_Module file. Signed-off-by: Mark Wielaard <[email protected]>
* Avoid double-including config.hUlf Hermann2017-05-021-0/+4
| | | | | | | | | | | | | | | | config.h doesn't have include guards, so including it twice is bad. We deal with this by checking for PACKAGE_NAME, but only in some places. Once we start using gnulib, we will need to include config.h before any gnulib-generated headers. This is problematic if we include it transitively through our own private headers. In order to set a clear rule about inclusion of config.h, it is now included in every .c file as first header, but not in any header. This will definitely avoid double-inclusion and satisfy the condition that it has to be included before gnulib headers. It comes at the price of adding some redundancy, but there is no clean way to avoid this. Signed-off-by: Ulf Hermann <[email protected]>
* 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

* 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]>
