IP.len is not recomputed when upper layer protocol has variable padding about pypacker HOT 2 CLOSED

Based on your description is assume the callflow (by ovverwriting bin()) is:
"overwritten bin()" -> "super.bin()" -> _update_fields() -> "overwritten bin() returns response of super.bin() + padding", so the padding isn't considered in _update_fields(). One option would be something like:

def bin(self, update_auto_fields=True):
  #  TODO: change body length to multiple of 4
  return pypacker.Packet.bin(self, update_auto_fields=update_auto_fields)

Update:
Length should be updated now with current master

Response timeout, closing ticket.
