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.

[AMF] Add support for SUCI protection schemes A and B (#1589)
For null protection scheme the SUCI needs to be BCD encoded. Whereas for
protection scheme profiles A and B the SUCI needs to be converted from
hexadecimal to ASCII.

This still needs the support for protection schemes A and B in UDM to
work.

Sukchan Lee cc03c91bdd [AMF] 5G-GUTI generation changed (#910)
The AMF shall assign a new 5G-GUTI for a particular UE:
a) during  a successful initial registration procedure;
b) during a successful registration procedure
   for mobility registration update; and
c) after a successful service request procedure invoked as a response
   to a paging request from the network and before the release
   of the N1 NAS signalling connection as specified in subclause 5.4.4.1.

The AMF should assign a new 5G-GUTI for a particular UE
during a successful registration procedure
for periodic registration update. The AMF may assign a new 5G-GUTI
at any time for a particular UE by performing
the generic UE configuration update procedure.

Sukchan Lee fc5c9b2af0 Try to fix the UE infinite attach (#568)
If both Delete-Session-Request/Response and
UEContextReleaseCommand/UEContextReleaseComplete are failed at the same time,
UE cannot attach to the EPC infinitely.

So, I've add the protection code
if timer expires when MME does not receive Delete-Session-Response.

Sukchan Lee 6f11a78079 If SCTP use SOCK_STREAM, Use BUFFERING method.
Most of the time, an application wants to perform some amount of data buffering
in addition to just responding to events. When we want to write data,
for example, the usual pattern runs something like:

1. Decide that we want to write some data to a connection;
   put that data in a buffer.
2. Wait for the connection to become writable
3. Write as much of the data as we can
4. Remember how much we wrote, and if we still have more data to write,
   wait for the connection to become writable again.

Now, Open5GS implements the above method by default when transmitting data
in a stream type socket.

Sukchan Lee d73ff77031 We cannot initialize the state in all cases. [#569]
In TS24.501 Ch 5.5.1.3.8 Abnormal cases on the network side

d) REGISTRATION REQUEST with 5GS registration type IE set to
"mobility registration updating" or "periodic registration updating"
received after the REGISTRATION ACCEPT message has been sent and
before the REGISTRATION COMPLETE message is received.

Since, we have to do this special case, it is desirable
to handle it directly inside the state(gmm-sm.c).
