	Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
  For each line:
    If doesn't contain `\bxmlns\b`:
      For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
        If both the HTTP and HTTPS versions
        return 200 OK and serve the same content:
          Replace HTTP with HTTPS.

Mono(tm) Binary Kernel Support for Linux
 | 
						|
-----------------------------------------
 | 
						|
 | 
						|
To configure Linux to automatically execute Mono-based .NET binaries
 | 
						|
(in the form of .exe files) without the need to use the mono CLR
 | 
						|
wrapper, you can use the BINFMT_MISC kernel support.
 | 
						|
 | 
						|
This will allow you to execute Mono-based .NET binaries just like any
 | 
						|
other program after you have done the following:
 | 
						|
 | 
						|
1) You MUST FIRST install the Mono CLR support, either by downloading
 | 
						|
   a binary package, a source tarball or by installing from Git. Binary
 | 
						|
   packages for several distributions can be found at:
 | 
						|
 | 
						|
	https://www.mono-project.com/download/
 | 
						|
 | 
						|
   Instructions for compiling Mono can be found at:
 | 
						|
 | 
						|
	https://www.mono-project.com/docs/compiling-mono/linux/
 | 
						|
 | 
						|
   Once the Mono CLR support has been installed, just check that
 | 
						|
   ``/usr/bin/mono`` (which could be located elsewhere, for example
 | 
						|
   ``/usr/local/bin/mono``) is working.
 | 
						|
 | 
						|
2) You have to compile BINFMT_MISC either as a module or into
 | 
						|
   the kernel (``CONFIG_BINFMT_MISC``) and set it up properly.
 | 
						|
   If you choose to compile it as a module, you will have
 | 
						|
   to insert it manually with modprobe/insmod, as kmod
 | 
						|
   cannot be easily supported with binfmt_misc.
 | 
						|
   Read the file ``binfmt_misc.txt`` in this directory to know
 | 
						|
   more about the configuration process.
 | 
						|
 | 
						|
3) Add the following entries to ``/etc/rc.local`` or similar script
 | 
						|
   to be run at system startup:
 | 
						|
 | 
						|
   .. code-block:: sh
 | 
						|
 | 
						|
    # Insert BINFMT_MISC module into the kernel
 | 
						|
    if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then
 | 
						|
        /sbin/modprobe binfmt_misc
 | 
						|
	# Some distributions, like Fedora Core, perform
 | 
						|
	# the following command automatically when the
 | 
						|
	# binfmt_misc module is loaded into the kernel
 | 
						|
	# or during normal boot up (systemd-based systems).
 | 
						|
	# Thus, it is possible that the following line
 | 
						|
	# is not needed at all.
 | 
						|
	mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
 | 
						|
    fi
 | 
						|
 | 
						|
    # Register support for .NET CLR binaries
 | 
						|
    if [ -e /proc/sys/fs/binfmt_misc/register ]; then
 | 
						|
	# Replace /usr/bin/mono with the correct pathname to
 | 
						|
	# the Mono CLR runtime (usually /usr/local/bin/mono
 | 
						|
	# when compiling from sources or CVS).
 | 
						|
        echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register
 | 
						|
    else
 | 
						|
        echo "No binfmt_misc support"
 | 
						|
        exit 1
 | 
						|
    fi
 | 
						|
 | 
						|
4) Check that ``.exe`` binaries can be ran without the need of a
 | 
						|
   wrapper script, simply by launching the ``.exe`` file directly
 | 
						|
   from a command prompt, for example::
 | 
						|
 | 
						|
	/usr/bin/xsd.exe
 | 
						|
 | 
						|
   .. note::
 | 
						|
 | 
						|
      If this fails with a permission denied error, check
 | 
						|
      that the ``.exe`` file has execute permissions.
