But consider that a subscriber-modify-v1 will now clear out the auth info when the newly added parameters are omitted. So it's not strictly backwards compatible, right? With the previous v1 I could only modify IMSI and MSISDN and leave algo and KI untouched. After this patch I will always either have to pass algo+KI again or they will be cleared out. Also, this will always clear out the lastauthtuple, regardless of the auth info being changed or not. Even if I again pass the same algo+KI as were stored previously. OTOH clearing might be good when the IMSI has changed?? :P Maybe it's better / less complex to have a separate command for auth or bump to v2... > + r = self.do_set('subscriber-modify-v1', '2620345,445566,xor') > + self.assertEquals(r['mtype'], 'ERROR') > + self.assertEquals(r['error'], 'Value failed verification.') I'm not familiar with the ctrl interface, but couldn't the error message be more descriptive, like "missing KI argument"? log msg: > The algorithm and ki are considered optional but if a valid > and non none algorithm is passed, a KI must be passed as well. rather say 'not-none' or 'a valid algorithm other than "none"'. ~Neels -------------- next part -------------- A non-text attachment was scrubbed...
