# _FORTIFY_SOURCE is a feature in gcc/glibc which is intended to provide extra
|
|
# security for detecting buffer overflows. Some distros (Ubuntu at the very least)
|
|
# have it enabled by default.
|
|
#
|
|
# gcc already optimizes some printf calls to call puts and/or putchar. When
|
|
# _FORTIFY_SOURCE is enabled and compiling with -O1 or greater, then some
|
|
# printf calls will also be optimized to call __printf_chk (in glibc). Any
|
|
# printfs which get redirected to __printf_chk are then no longer synchronized
|
|
# with printfs that go through mp_printf.
|
|
#
|
|
# In MicroPython, we don't want to use the runtime library's printf but rather
|
|
# go through mp_printf, so that stdout is properly tied into streams, etc.
|
|
# This means that we either need to turn off _FORTIFY_SOURCE or provide our
|
|
# own implementation of __printf_chk. We've chosen to turn off _FORTIFY_SOURCE.
|
|
# It should also be noted that the use of printf in MicroPython is typically
|
|
# quite limited anyways (primarily for debug and some error reporting, etc
|
|
# in the unix version).
|
|
#
|
|
# Information about _FORTIFY_SOURCE seems to be rather scarce. The best I could
|
|
# find was this: https://securityblog.redhat.com/2014/03/26/fortify-and-you/
