Description

While running osmo-gbproxy 8343b4adbbe9afd4294232429696ee9736ec1004 today, I saw this log line:

<0012> gprs_gb_parse.c:384 Unhandled GSM 04.08 message type AUTH & CIPHER REQUEST for protocol discriminator GMM.

I could not gather more info since I had enabled debug all and my terminal buffer overflowed quickly.

So it seems GSM48_MT_GMM_AUTH_CIPH_REQ message is not being handled in gprs_gb_parse_dtap().

We are removing all those "deep packet inspection" and rewrite features from gb-proxy, so I'm rejecting this old bug report.
