( https://gerrit.osmocom.org/c/osmocom-bb/+/34031 ) Change subject: layer23: modem: gmm: Adapt log string about no TLLI found ...................................................................... layer23: modem: gmm: Adapt log string about no TLLI found During initial GMM Attach, the GMM layer generates an internal local TLLI and uses it to do the GMM Attach. Only at the time it receives the GMM Attach Accept with the assigned TLLI from the network then explicitly informs other layers about the TLLI update. Hence, the GMMREG user doesn't really know about the TLLI in use until the GMM Attach success happens (gmmreg-attach.cnf). During that time, the TLLI at the app is basically unassigned (0xffffffff). Hence, during that same time a TLLI update hook in GMMRR-Assign.req will not work since the app is unaware of the remporary local TLLI, so no match can be done. In that specific scenario, that's fine, since anyway it is waiting to receive the GMMREG-Attach.cnf, which will indicate the assigned TLLI to it. In summary, not being able to match the TLLI in GMMRR-Assign.req is not bad per se, so soften the log error there.
