Hi,
I think we have a bug in packet_utils.checksum, please check it:
=============================
def checksum(data, start, skip_word = 0):
if len(data) % 2 != 0:
arr = array.array('H', data[:-1])
else:
arr = array.array('H', data)
if skip_word:
for i in range(0, len(arr)):
if i == skip_word:
continue
start += arr[i]
else:
for i in range(0,len(arr)): # BUG?
start += arr[i] # BUG?
# IT should be :
# for i in range(0, len(arr)-1,2):
# start += arr[i]*0x100 +arr[i+1]
if len(data) % 2 != 0:
start += struct.unpack('H', data[-1]+'\0')[0]
start = (start >> 16) + (start & 0xffff)
start += (start >> 16);
return ntohs(~start & 0xffff)
===============================
Thanks,
Ibrahim
