Hello Max, Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/3127
to look at the new patch set (#8).
transaction: reject calls from unidentified subscribers
A valid subscriber is indespensible when allocating a new
transaction. Return NULL if no subscriber is supplied. This
will cause unidentified subscribers to be rejected.
Note: Under normal conditions, the problem does not occour,
but it is still possible that a misbehaving MS might trigger
the problem by sending a SETUP command before authenticating
the subscriber. (unencrypted networks)
