______________________________________________________________________________
An update that solves 14 vulnerabilities, contains four
features and has 5 fixes is now available.
Description:
This update for binutils fixes the following issues:
- For compatibility on old code stream that expect 'brcl 0,label' to not
be disassembled as 'jgnop label' on s390x. (bsc#1192267) This reverts
IBM zSeries HLASM support for now.
- Fixed that ppc64 optflags did not enable LTO (bsc#1188941).
- Fix empty man-pages from broken release tarball
- Fixed a memory corruption with rpath option (bsc#1191473).
- Fixed slow performance of stripping some binaries (bsc#1183909).
Update to binutils 2.37:
* The GNU Binutils sources now requires a C99 compiler and library to
build.
* Support for Realm Management Extension (RME) for AArch64 has been added.
* A new linker option '-z report-relative-reloc' for x86 ELF targets has
been added to report dynamic relative relocations.
* A new linker option '-z start-stop-gc' has been added to disable special
treatment of __start_*/__stop_* references when
--gc-sections.
* A new linker options '-Bno-symbolic' has been added which will cancel
the '-Bsymbolic' and '-Bsymbolic-functions' options.
* The readelf tool has a new command line option which can be used to
specify how the numeric values of symbols are reported.
--sym-base=0|8|10|16 tells readelf to display the values in base 8, base
10 or base 16. A sym base of 0 represents the default action
of displaying values under 10000 in base 10 and values above that in
base 16.
* A new format has been added to the nm program. Specifying
'--format=just-symbols' (or just using -j) will tell the program to
only display symbol names and nothing else.
* A new command line option '--keep-section-symbols' has been added to
objcopy and strip. This stops the removal of unused section symbols
when the file is copied. Removing these symbols saves space, but
sometimes they are needed by other tools.
* The '--weaken', '--weaken-symbol' and '--weaken-symbols' options
supported by objcopy now make undefined symbols weak on targets that
support weak symbols.
* Readelf and objdump can now display and use the contents of .debug_sup
sections.
* Readelf and objdump will now follow links to separate debug info files
by default. This behaviour can be stopped via the use of the new '-wN'
or '--debug-dump=no-follow-links' options for readelf and the '-WN' or
'--dwarf=no-follow-links' options for objdump. Also the old behaviour
can be restored by the use of the '--enable-follow-debug-links=no'
configure time option.
The semantics of the =follow-links option have also been slightly
changed. When enabled, the option allows for the loading of symbol tables
and string tables from the separate files which can be used to enhance the
information displayed when dumping other sections, but it does not
automatically imply that information from the separate files should be
displayed.
If other debug section display options are also enabled (eg
'--debug-dump=info') then the contents of matching sections in both the
main file and the separate debuginfo file *will* be displayed. This is
because in most cases the debug section will only be present in one of the
files.
If however non-debug section display options are enabled (eg
'--sections') then the contents of matching parts of the separate
debuginfo file will *not* be displayed. This is because in most cases the
user probably only wanted to load the symbol information from the separate
debuginfo file. In order to change this behaviour a new command line
option --process-links can be used. This will allow di0pslay options to
applied to both the main file and any separate debuginfo files.
* Nm has a new command line option: '--quiet'. This suppresses "no
symbols" diagnostic.
Update to binutils 2.36:
New features in the Assembler:
- General:
* When setting the link order attribute of ELF sections, it is now
possible to use a numeric section index instead of symbol name.
* Added a .nop directive to generate a single no-op instruction in a
target neutral manner. This instruction does have an effect on DWARF
line number generation, if that is active.
* Removed --reduce-memory-overheads and --hash-size as gas now uses
hash tables that can be expand and shrink automatically.
- X86/x86_64:
* Add support for AVX VNNI, HRESET, UINTR, TDX, AMX and Key Locker
instructions.
* Support non-absolute segment values for lcall and ljmp.
* Add {disp16} pseudo prefix to x86 assembler.
* Configure with --enable-x86-used-note by default for Linux/x86.
- ARM/AArch64:
* Add support for Cortex-A78, Cortex-A78AE and Cortex-X1, Cortex-R82,
Neoverse V1, and Neoverse N2 cores.
* Add support for ETMv4 (Embedded Trace Macrocell), ETE (Embedded Trace
Extension), TRBE (Trace Buffer Extension), CSRE (Call Stack Recorder
Extension) and BRBE (Branch Record Buffer Extension) system registers.
* Add support for Armv8-R and Armv8.7-A ISA extensions.
* Add support for DSB memory nXS barrier, WFET and WFIT instruction for
Armv8.7.
* Add support for +csre feature for -march. Add CSR PDEC instruction
for CSRE feature in AArch64.
* Add support for +flagm feature for -march in Armv8.4 AArch64.
* Add support for +ls64 feature for -march in Armv8.7 AArch64. Add
atomic 64-byte load/store instructions for this feature.
* Add support for +pauth (Pointer Authentication) feature for
-march in AArch64.
New features in the Linker:
* Add --error-handling-script=<NAME> command line option to allow a
helper script to be invoked when an undefined symbol or a missing
library is encountered. This option can be suppressed via the
configure time switch: --enable-error-handling-script=no.
* Add -z x86-64-{baseline|v[234]} to the x86 ELF linker to mark
x86-64-{baseline|v[234]} ISA level as needed.
* Add -z unique-symbol to avoid duplicated local symbol names.
* The creation of PE format DLLs now defaults to using a more secure set
of DLL characteristics.
* The linker now deduplicates the types in .ctf sections. The new
command-line option --ctf-share-types describes how to do this: its
default value, share-unconflicted, produces the most compact
output.
* The linker now omits the "variable section" from .ctf sections by
default, saving space. This is almost certainly what you want unless
you are working on a project that has its own analogue of symbol
tables that are not reflected in the ELF symtabs.
New features in other binary tools:
* The ar tool's previously unused l modifier is now used for specifying
dependencies of a static library. The arguments of this option (or
--record-libdeps long form option) will be stored verbatim in the
__.LIBDEP member of the archive, which the linker may read at link
time.
* Readelf can now display the contents of LTO symbol table sections when
asked to do so via the --lto-syms command line
option.
* Readelf now accepts the -C command line option to enable the
demangling of symbol names. In addition the --demangle=<style>,
--no-demangle, --recurse-limit and --no-recurse-limit options are also
now availale.
