ELFUTILS 0.172 - http://elfutils.org/

A new release of elfutils is available at:
ftp://sourceware.org/pub/elfutils/0.172/
or https://sourceware.org/elfutils/ftp/0.172/

* NEWS *

No functional changes compared to 0.171.

Various bug fixes in libdw and eu-readelf dealing with bad DWARF5 data.
Thanks to running the afl fuzzer on eu-readelf and various testcases.

eu-readelf -N is ~15% faster.

* GIT SHORTLOG *

Mark Wielaard (31):
  tests: Drop shared libraries from
self_test_files_exe.
  readelf: Call __fsetlocking (stdout,
FSETLOCKING_BYCALLER).
  readelf: Lookup gettext "yes" and "no" only
once.
  readelf: Don't allocate string with asprintf, but reuse buffer
with
           sprintf.
  readelf: Lookup "no" translation for no_str,
not "yes".
  libdwfl: Make __libdwfl_addrsym a static function in
       
   dwfl_module_addrsym.c
  readelf: Make room for DW_MACRO_hi_user
opcode if used.
  libdw: Make sure id_path can contain max number of
build id bytes.
  readelf: Don't leak lengths array when detecting an
invalid hash
           chain.
  libdw: Make sure dirarray is always
properly freed in
         dwarf_getsrclines.
  libdw: Don't leak arange
if we cannot figure out which CU it belongs.
  readelf: Set begin
properly for DW_LLE_GNU_start_end_entry on addrx
           failure.
 
readelf: Always initialize .debug_addr unit_length, even without
       
   header.
  libdw: Explicitly check we could decode diridx in
dwarf_getsrclines.
  tests: Use error, not assert, when trying to print
a non-base type
         DIE.
  libdw: Report error in
dwarf_getlocation_die for bogus opcode offset.
  libdw: Check DIE
address fall inside the CU before reading abbrev.
  libdw: Make sure
that address_size and offset_size are 4 or 8 bytes.
  readelf: Turn
format_print_dwarf into print_dwarf_addr.
  libdw: Return an error in
dwarf_getlocation_attr for missing
         .debug_addr.
  readelf,
libdw: Handle too many directories or files in the line
                
 table better.
  tests: Fix cfi_debug_bias assert in varlocs.
  libdw:
Detect bad DWARF in store_implicit_value.
  libdw: dwarf_get_units
should handle existing failure to open Dwarf.
  libdw: Check validity of
dwarf_getabbrev arguments.
  tests: Don't assert on bad
DW_OP_GNU_parameter_ref target in varlocs.
  readelf: Calculate
max_entries instead of needed bytes
           (and overflowing).
 
libdw: Break long or circular DIE ref chains in
        
dwarf_[has]attr_integrate.
  readelf: Fix bounds check in
print_form_data.
  readelf: Return correct readp (or readendp) from
print_form_data.
  Prepare for 0.172.
