An update that solves 8 vulnerabilities, contains three features and has 6
fixes is now available.
Description:
This update for binutils fixes the following issues:
binutils was updated to version 2.35.1 (jsc#ECO-2373)
Additional branch fixes applied on top of 2.35.1:
o Fixes PR26520, aka [bsc#1179036], a problem in addr2line with certain DWARF
variable descriptions.
o Also fixes PR26711, PR26656, PR26655, PR26929, PR26808, PR25878, PR26740,
PR26778, PR26763, PR26685, PR26699, PR26902, PR26869, PR26711
o The above includes fixes for dwo files produced by modern dwp, fixing
several problems in the DWARF reader.
Update to binutils 2.35.1 and rebased branch diff:
o This is a point release over the previous 2.35 version, containing bug
fixes, and as an exception to the usual rule, one new feature. The new
feature is the support for a new directive in the assembler: ".nop". This
directive creates a single no-op instruction in whatever encoding is
correct for the target architecture. Unlike the .space or .fill this is a
real instruction, and it does affect the generation of DWARF line number
tables, should they be enabled.
Update to binutils 2.35:
o The assembler can now produce DWARF-5 format line number tables.
o Readelf now has a "lint" mode to enable extra checks of the files it is
processing.
o Readelf will now display "[...]" when it has to truncate a symbol name. The
old behaviour - of displaying as many characters as possible, up to the 80
column limit - can be restored by the use of the --silent-truncation
option.
o The linker can now produce a dependency file listing the inputs that it has
processed, much like the -M -MP option supported by the compiler.
o fix DT_NEEDED order with -flto [bsc#1163744]
Update to binutils 2.34:
o The disassembler (objdump --disassemble) now has an option to generate
ascii art thats show the arcs between that start and end points of control
flow instructions.
o The binutils tools now have support for debuginfod. Debuginfod is a HTTP
service for distributing ELF/DWARF debugging information as well as source
code. The tools can now connect to debuginfod servers in order to download
debug information about the files that they are processing.
o The assembler and linker now support the generation of ELF format files for
the Z80 architecture.
o Add new subpackages for libctf and libctf-nobfd.
o Disable LTO due to bsc#1163333.
o Includes fixes for these CVEs: bsc#1153768 aka CVE-2019-17451 aka PR25070
bsc#1153770 aka CVE-2019-17450 aka PR25078
o fix various build fails on aarch64 (PR25210, bsc#1157755).
Update to binutils 2.33.1:
o Adds support for the Arm Scalable Vector Extension version 2 (SVE2)
instructions, the Arm Transactional Memory Extension (TME) instructions and
the Armv8.1-M Mainline and M-profile Vector Extension (MVE) instructions.
o Adds support for the Arm Cortex-A76AE, Cortex-A77 and Cortex-M35P
processors and the AArch64 Cortex-A34, Cortex-A65, Cortex-A65AE,
Cortex-A76AE, and Cortex-A77 processors.
o Adds a .float16 directive for both Arm and AArch64 to allow encoding of
16-bit floating point literals.
o For MIPS, Add -m[no-]fix-loongson3-llsc option to fix (or not) Loongson3
LLSC Errata. Add a --enable-mips-fix-loongson3-llsc=[yes|no] configure time
option to set the default behavior. Set the default if the configure option
is not used to "no".
o The Cortex-A53 Erratum 843419 workaround now supports a choice of which
workaround to use. The option --fix-cortex-a53-843419 now takes an optional
argument --fix-cortex-a53-843419[=full|adr|adrp] which can be used to force
a particular workaround to be used. See --help for AArch64 for more
details.
o Add support for GNU_PROPERTY_AARCH64_FEATURE_1_BTI and
GNU_PROPERTY_AARCH64_FEATURE_1_PAC in ELF GNU program properties in the
AArch64 ELF linker.
o Add -z force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
on output while warning about missing GNU_PROPERTY_AARCH64_FEATURE_1_BTI on
inputs and use PLTs protected with BTI.
o Add -z pac-plt for AArch64 to pick PAC enabled PLTs.
o Add --source-comment[= ] option to objdump which if present, provides a
prefix to source code lines displayed in a disassembly.
o Add --set-section-alignment = option to objcopy to allow the changing of
section alignments.
o Add --verilog-data-width option to objcopy for verilog targets to control
width of data elements in verilog hex format.
o The separate debug info file options of readelf (--debug-dump=links and
--debug-dump=follow) and objdump (--dwarf=links and --dwarf=follow-links)
will now display and/or follow multiple links if more than one are present
in a file. (This usually happens when gcc's -gsplit-dwarf option is used).
In addition objdump's --dwarf=follow-links now also affects its other
display options, so that for example, when combined with --syms it will
cause the symbol tables in any linked debug info files to also be
displayed. In addition when combined with --disassemble the --dwarf=
follow-links option will ensure that any symbol tables in the linked files
are read and used when disassembling code in the main file.
o Add support for dumping types encoded in the Compact Type Format to objdump
and readelf.
o Includes fixes for these CVEs: bsc#1126826 aka CVE-2019-9077 aka PR1126826
bsc#1126829 aka CVE-2019-9075 aka PR1126829 bsc#1126831 aka CVE-2019-9074
aka PR24235 bsc#1140126 aka CVE-2019-12972 aka PR23405 bsc#1143609 aka
CVE-2019-14444 aka PR24829 bsc#1142649 aka CVE-2019-14250 aka PR90924
o Add xBPF target
o Fix various problems with DWARF 5 support in gas
o fix nm -B for objects compiled with -flto and -fcommon.
