Sukchan Lee 561f1ac2f3 This always true. So I fixed it (#1266) 2021-12-08 20:56:26 +09:00
Sukchan Lee aab8286401 [MME] fix the crash issue if enb_ue is NULL(#1275) 
An assert occurs when a NAS message retransmission occurs.

Because there is no `enb_ue` context.

Therefore, before removing enb_ue, all Timers must be stopped
to prevent retransmission of NAS messages.

 2021-10-16 14:11:43 +09:00
Sukchan Lee 13f1b390ae CVE-2021-41794 from NCC Group by Mark Tedman 
When connecting to the UPF port for the PFCP protocol (8805) and sending
an association setup request followed by a session establishment request
with a PDI Network Instance set to ‘internet’, it causes a stack corruption
to occur.

So, ogs_fqdn_parse() fixed.

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 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.
