I don't actually think that the referenced patch from one year ago (https://gerrit.osmocom.org/c/osmo-msc/+/15175) works.

While one can now select whether encryption should be enabled or disable in UTRAN, the code never passses the ck to ranap_new_msg_sec_mod_cmd() and hence the air interface will always only use integrity protection and no encryption at all:
The ck argument is always NULL, I don't see how the proper key would have ever been passed down?
