Another more secure option, if all you need is to generate a uuid and you
don't need to use ctypes for anything else, is to generate an
RFC 4122-compliant random uuid as follows. This allows you to omit
importing the python uuid module, which in turn imports ctypes.
(This works because SELinux allows reading from /dev/urandom under
the default policy rules)
def make_random_uuid():
bytes = open('/dev/urandom','rb').read(16)
num = long(('%02x'*16) % tuple(map(ord, bytes)), 16)
# Set the variant to RFC 4122.
num &= ~(0xc000 << 48L)
num |= 0x8000 << 48L
# Set the version number (4 = random uuid).
num &= ~(0xf000 << 64L)
num |= 4 << 76L
# Convert to hex-string format
hex = '%032x' % num
return '%s-%s-%s-%s-%s' % (
hex[:8], hex[8:12], hex[12:16], hex[16:20], hex[20:])
