Description

This obviously doesn't make sense:

<000f> ran_peer.c:138 ran_peer(UTRAN-Iu:RI-SSN_PC:PC-0-150-3:SSN-RANAP)[0x56063f4ac550]{READY}: Failed parsing TLV looking for Osmux support

neels Why do you say it doesn't make sense? AFAIU osmux is used in the core network starting from osmo-mgw, so it's unrelated to the RAN technology in use?

#2 Updated by neels 16 days ago

I didn't say that :P

But it does make sense because it is on IuCS, and the hNodeBs we support definitely don't support osmux

pespin and especially because using the GSM 08.08 TLV definitions on a RANAP encoded message is plain wrong.

Decoding a message in ran_peer.c is completely the wrong place.
I'm moving it in https://gerrit.osmocom.org/c/osmo-msc/+/19024
