jmasterfunk84 47cbaca149 [MME] Introduce support for S6a Cancel Location Request 
- Added diameter dictionary definitions for Cancel Location
- Cancel Location will completely remove UE from MME, allow for a fresh IMSI attach to occur on next attempt.
- T3422 is used for detach request.
- Added new handling for s6a events in mme-sm, as not all s6a messages are at attach now.  Maybe there's something in a state machine I should've been using here instead of a new flag?

- Testing was completed with UE in idle and connected.  With CLR flags indicating re-attach required and without.  Also sending CLR after UE detach.  And then sending again when mme_ue is empty.

jmasterfunk84 68140efce4 [MME] Handle Charging Characteristics 
Found no support for HSS provided charging characteristics.  Following TS32.251 A.4:
- Use PDN level CC, if one wasn't provided then use subscription level CC
- Don't send CC in S11 if it wasn't included
 2022-07-24 12:29:01 +09:00
jmasterfunk84 d2ef555ce4 Set default Network-Access-Mode to 0 
For HSS's which do not include the NAM, the MME should not treat this as a fatal error.  MME should just assume PACKET_AND_CIRCUIT (0), as was decided in a previous PR.

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

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.

Introduce Gn interface (GTPv1C) Support to PGW (#1351) 
* [CORE] tlv: Store mode in ogs_tlv_t

This allows specifying the format of the IE for each individual IE,
hence allowing messages containing IEs formatted in different ways.

This is needed in order to support parsing GTPv1-C, since messages
contain IEs with different structure (TLV vs TV). Hence, this is a
preparation patch to add support for parsing TVs in ogs-tlv.c/.h.

* [CORE] tlv: Support parsing msg with both TLV and TV in it

IEs of type TV are sometimes used in GTPv1-C. Current tlv parser/builder
doesn't provide with ways to parse messages which contain TV formatted
IEs. This patch adds the relevant types and ways to encode/decode them.

Furthermore, the current parser/builder allows parsing/building messages
containing the exact same format in all its IEs. A new parser function
is added which allows parsing messages of different types (TV, TLV)
mixed in the same message. In order to be able to do so, it uses the
general msg_mode passed to it in order to know the general TLV format
(in essence, the length of the Tag field, and also the length of the
Length field if applicable each IE).

Looking up the instance in the TLV description is left undone and
hadcoded to 0, since the only user so far requiring this API is GTPv1-C,
which has no instances.

* [CORE] tlv: Support repeated tag+instance parsing TLV message

In GTPv2C, repeated IEs (same tag) are easily differentiated by the
Instance byte, which provides info to match different decoded
structures. In GTPv1C though, there's no Instance byte, and we still
encounter repeated IEs (like GSN Address in Create PDP Context Request).
Hence, the TLV decoder needs to be updated to track count of IEs found
(identified by tag+instance, where instance is always 0 in GTPv1C) and
get the proper description index + offset into the decoded structure.

* [GTP]: Move GTPv2-C specifics to its own libgtp subdir

This will allow adding GTPv1-C code by the side. Most GTPv2 code is left
in this patch as "gtp" instead of renaming it to "gtp2" in order to
avoid massive changes. It can be done at a later stage if wanted.

* [GTP] Support generating GTPv1-C messages

* [SMF] Add Gn interface support

This patch introduces GTPv1C support to open5gs-smfd. With it,
open5gs-becomes a GGSN too, where SGSN can connect to, hence supporting
GERAN and UTRAN networks.

Sukchan Lee 79239d8eff [IMPORTANT] changed network_access_mode: 0 (#1323) 
The network access mode of HSS has been changed to 0 (Packet and Circuit).

Versions of MME prior to v2.4.2 did not use this value. Open5GS set
the attach result of Attach Complete message as it is by looking
at the attach type of the Attach Request message.

Now, if the network access mode of HSS is set to 2 (Only Packet),
this value is affected by MME from v2.4.3. Regardless of the attach type
of the Attach Request, the MME will set EPS Only to the attach result
of Attach Complete.

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 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.
