Sukchan Lee 1dc692753a [AMF] Distinguish Cleartext/Non-cleartext (#958)
1. If UE does not use a NAS container for Non-cleartext IEs,
   Open5GS AMF will send Registration reject message.
2. If UE sends Non-cleartext IEs without Integrity-protected,
   Open5GS AMF will send Registration reject message.
3. If UE does not send NAS container in Security mode complete message,
   Open5GS AMF will send Registration reject message.

By default, PFCP round robin selection is allowed.
The above parameters prohibit selecting PFCP in a round robin manner.

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.

AMF checks whether it can serve all the S-NSSAI(s) from
the Requested NSSAI present in the Subscribed S-NSSAIs
(potentially using configuration for mapping S-NSSAI values
between HPLMN and Serving PLMN), or all the S-NSSAI(s) marked
as default in the Subscribed S-NSSAIs in the case that
no Requested NSSAI was provided or none of the S-NSSAIs
in the Requested NSSAI are permitted,
i.e. do not match any of the Subscribed S-NSSAIs or not available
at the current UE's Tracking Area (see clause 5.15.3).

Sukchan Lee 776d323a16 fix: Change UE Context Request IE handling (#771)
Previously, AMF would sends PDUSessionResourceSetupRequest
when the following conditions were met:
- gNB didn't send UE Context Request IE of InitialUEMessage
- AMF should send SMF generated TRANSFER message(PDU_RES_SETUP_REQ)
to the gNB

However, in issues #771, the gNB did not accept
PDUSessionResourceSetupRequest. Perhaps the gNB engineer thought
that if gNB needs to send data traffic to the UE, AMF should send
an InitialContextSetupRequest regardless of UE Context Request IE.
This is because gNB requires the kgNB security context
for data connection.

So, in this case, Open5GS-AMF decided to send
an InitialContexSetupRequest regardless of
whether it received UE Context Request IE of InitialUEMessage.

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 1bed0d5872 [#568] Add GTP-U Error Indication Handling
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.

Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.

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).
