I have found two bugs in file packet-bssgp.c. The patch-file with my proposal
of solution you can find in attachement.
First problem is in function de_bssgp_pdu_in_error. There is used byte '0' of
message stream as a pduType, but this field in 'Pdu in error' is not the same
as pduType of the message, there should be read another byte from the stream so
I said there 'curr_offset' instead of '0'.
Second problem is in function de_bssgp_ran_inf_error_rim_cont. Error rim
container doesn't have field rim sequence number. This field exists in the rest
of containers but not in this one. So I have removed this field.
In this function we have field pdu in error and this field is mandatory, not
optional as you have wrote there.
I have tested my solutions with using of real stream.
Best Regards
