[ Upstream commit7c5b019e3a] Fix buffer overflow observed when running perf test. The overflow is when trying to evaluate "1ULL << (64 - 1)" which is resulting in -9223372036854775808 which overflows the 20 character buffer. If is possible this bug has been reported before but I still don't see any fix checked in: See: https://www.spinics.net/lists/linux-perf-users/msg07714.html Reported-by: Michael Sartain <mikesart@fastmail.com> Reported-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Tony Jones <tonyj@suse.de> Acked-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Fixes:f7d82350e5("tools/events: Add files to create libtraceevent.a") Link: http://lkml.kernel.org/r/20190228015532.8941-1-tonyj@suse.de Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
