( https://gerrit.osmocom.org/c/osmo-msc/+/26391 ) Change subject: ran_msg_iu: ensure UEA0 is not passwd to ranap_new_msg_sec_mod_cmd2() ...................................................................... ran_msg_iu: ensure UEA0 is not passwd to ranap_new_msg_sec_mod_cmd2() Since ranap_new_msg_sec_mod_cmd2() doesn't support UEA0 we must not pass it to it. The reason behind is that UEA0 can't passed in the TLV of a SecurityCommand and is implicit UEA0 if the TLV is not present.
