Bug ID: 22037
   Summary: Fuzz binutils on OSS-Fuzz
   Product: binutils
   Version: unspecified
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: konstantin.s.serebryany at gmail dot com
CC: nickc at redhat dot com
  Target Milestone: ---

OSS-Fuzz is a continuous automated fuzzing service, available for open-source
software for free. 
https://github.com/google/oss-fuzz
https://opensource.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html

Given the recent findings in readelf
(http://seclists.org/oss-sec/2017/q1/635)
you may be interested in setting up continuous fuzzing with OSS-Fuzz. 

Nick, FYI, there are other folks in redhat who already use OSS-Fuzz,
see e.g.
https://github.com/google/oss-fuzz/blob/master/projects/libreoffice/project.yaml

PR gold/21868
* aarch64.cc (AArch64_relobj::try_fix_erratum_843419_optimized):
Add extra view offset argument to function.
(AArch64_relobj::fix_errata_and_relocate_erratum_stubs): Add
extra view offset set to the output offset when the view has
is_input_output_view set, since it has not already been
included. Pass this to try_fix_erratum_843419_optimized.
