Description

i verified this bug on osmo-msc nightly build today

to reproduce:
remove all occurences of cs7 from the config file.
restart osmo-msc
connect to vty
type 'write'
check config file.

it will contain at least this snippet in addition now:

cs7 instance 0
 point-code 0.23.1
 asp asp-clnt-OsmoMSC-A-Iu 2905 0 m3ua
  remote-ip 127.0.0.1
 as as-clnt-OsmoMSC-A-Iu m3ua
  asp asp-clnt-OsmoMSC-A-Iu
  routing-key 3 0.23.1
msc
 cs7-instance-a 0
 cs7-instance-iu 0

  • Project changed from OsmoMSC to libosmo-sccp + libosmo-sigtran
  • Assignee set to stsp

this is most likely a libosmo-sigtran bug. The configuration should only write those parts which are explicitly configured, and not routes as/asp's which are dynamically created as automatism of the "simple client".

Note that osmo-msc has to pass a default point code to the ss7 API (this is enforced by the API).

I suppose this means that this part will always have to be written out:

cs7 instance 0
 point-code 0.23.1

and thus also the following lines, because they reference this cs7 instance:

msc
 cs7-instance-a 0
 cs7-instance-iu 0

I have proposed a patch at https://gerrit.osmocom.org/#/c/libosmo-sccp/+/11509

This disables writing out default AS/ASP config items shown in the issue description.

For consistency, I have checked the simple-server implementation for this problem as well.
It looks like dynamic AS/ASP created in server mode are already omitted from the configuration file when the config is written out.

Does anyone see anything else that needs to be done for this issue?

crickets

Sounds like nothing else seems to be needed. Closing this issue.
