Subject: [Wireshark-dev] ASN.1 bit string alignment
In 1.0.x PER ASN.1 bit strings used to be padded in the MSBs, (e.g.
extract from an RRC message):
dl-HFN: 00000004 [bit length 25]
Since 1.2.x they appear to be padded in the LSBs (e.g. the same
extract):
dl-HFN: 00000200 [bit length 25]
The value carried in both cases above is meant to be 4.
Is this a deliberate change?
I know bit strings are of arbitrary length, therefore a "natural"
representation is challenging, but I find the above counter-intuitive.
Neil
