Sukchan Lee 715e4c0b50 Shall cipher in the NAS message container IE 
3GPP TS 24.501 version 16.6.0 Release 16
4.4 NAS security
4.4.6 Protection of initial NAS signalling messages

1) the UE needs to send non-cleartext IEs in a REGISTRATION REQUEST
or SERVICE REQUEST message, the UE includes the entire REGISTRATION
REQUEST or SERVICE REQUEST message (i.e. containing both cleartext IEs
and non-cleartext IEs) in the NAS message container IE and shall cipher
the value part of the NAS message container IE. The UE shall then send
a REGISTRATION REQUEST or SERVICE REQUEST message containing
the cleartext IEs and the NAS message container IE;

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.

Sukchan Lee ea89d8dc8e [AMF] Added RANConfigurationUpdate (#943) 2021-04-16 16:26:13 +09:00
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 b22023afb8 fix: creating allowed NSSAI (#859) 
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 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 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.
