Sukchan Lee 5295c108ad Added Service-based NF discovery 
== Known limitation ==
Placing npcf-smpolicycontrol and pcf-policyauthorization
in different NFs is not supported. Both npcf-smpolicycontrol
and pcf-policyauthorization should be placed in the same NF.

Sukchan Lee 668cc59f94 [AMF] Fixed 5GMM cause in Reject message (#1660) 
When a UE that requests slices tries to connect and there are no slices configured, the reject message is:

5GMM cause = 0x7 (5GS Services not allowed)

however it should be:

5GMM cause = 0x3e (No network slices available)

All 5GMM cause value in reject message is reviewed in this commit

Sukchan Lee e0a487f479 [SMF] Optimiza Session Modification Message 
For video in VoNR, multiple QosFlow is required in one session.

In the past, since only one Session Modification Message was supported,
QoS-Flow was put into several Session Messages one by one and processed.

Now that multiple QoS-Flows can be supported,
it is optimized to process one session modification message.

Rename GTPv2C specifics to gtp2 prefix (#1485) 
In the past only GTPv2C was supported, and had the "gtp" generic prefix.
Later on, GTPv1C support was added, and "gtp1" prefix was used.
Let's move GTPv2C specific bits to have "gtp2" prefix too, and leave
"gtp" prefix for generic stuff among different GTP versions.

Sukchan Lee 253e2ad98a [GTP/PFCP] Support VRF (#1404) 2022-03-07 22:43:18 +09:00
Pau Espin 7bddc92322 [GTP] Support binding socket to device 
This is useful, among other possible applications, to make use of VRFs [1],
in this case for GTP-C and GTP-U traffic in the PGW.

The bind_dev field is added to the ogs_socknode_t so that it's easy to
extend its use into lots of other sockets being set up based on config
file information.

Sukchan Lee ed3444eef5 Need to increase NF ref_count 
1. UE registered and PDU established.
2. PCF does not receive Heartbeat.
 - PCF De-registered state.
 - Since PDU is established, SMF should not remove NF instance
3. PCF re-registered.
 - HERE, WE NEED TO INCREASE NF REFERENCE COUNT.
   Otherwise, NF instance will be removed if PCF is de-registered state
4. UE sends PDU release request.
5. Because SMF knows PCF NF instance, SMF can send PCF delete
