Description

When BVCI A first establishes a connection through NSVCI/NSEI B, then later establishes a connection through NSVCI/NSEI A, gb_proxy permanently keeps a stale proxy mapping associating BVCI A with NSVCI B.

This causes all downlink messages from the SGSN to be routed still through NSVCI B, despite now NSVCI A being the correct one.

I would expect this to not be an isuse with the new architecture/rewrite?

#10 Updated by daniel 9 days ago

Yeah, the BVCI <-> NSVCI mapping doesn't even make sense now that one NSE could have multiple NSVCs.

Not sure if we have a similar issue in the new gbproxy or if it is already taken care of. Some code related to this got #if 0'd in rx_bvc_reset_from_bss() (gbproxy.c line 793).

In gb_proxy.c:597 the old bvc is freed if a cell exists and points to (the old) bvc.

So I would think this is not an issue anymore.
