Package: python-scapy
Version: 2.3.3-3
Severity: normal
Consider the following example, based on the codepath in
arch/linux.py's read_routes6 (the example is compatible with both
python 2.7 and python3, so that i could test against python3-scapy):
----------------
import struct
import scapy.utils6
import codecs
f1 = b'20010db8000000010000000000000000'
print(f1)
f2 = struct.unpack('4s4s4s4s4s4s4s4s', f1)
print(f2)
f3= b':'.join(f2)
print(f3)
f4 = codecs.decode(f3)
print(f4)
f5 = scapy.utils6.in6_ptop(f4)
print(f5)
----------------
The final result should be:
2001:db8:0:1::
but it currently returns:
2001:db8::1::
which is not a valid IPv6 representation because there are two groups
of :: in the address.
fwiw, python3-scapy does not have the same problem; rather, it returns
the correct address.
