Sukchan Lee 321c8d4cf9 [SGsAP] Changed message if Paging failed (#1701) 
The problem occurred in the following scenario:

1. VLR sent PAGING-REQUEST to the MME
2. MME sent S1-Paging to the UE
3. Paging failed
4. MME responded SERVICE-REQUEST to the VLR
5. VLR sent DOWNLINK-UNITDATA to the MME
6. Even though there is no S1 Context,
   MME try to sent DownlinkNASTransport message to the UE.
7. So, the problem occurred.

I've changed the number 4 PAGING-REJECT instead of SERVICE-REQUEST.

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.

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

Sukchan Lee 866ae78f5e [NRF] fix the crash for invalid FQDN (#1333) 2022-01-22 09:34:38 +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.

Spencer Sevilla 5b59f09d9f ogs_assert to ogs_expects (#314) 
* HACK: Don't retransmit InitialContextSetupReq

Related: #256

* HACK: Don't use buggy sa1p_copy()  in eNBConfigTransfer

Related: #257

* mme: don't reject with 'IMSI is unknown in HLR' (permanent reject)

* MME: Implement S6a result -> EMM cause code mapping

Closes: #263

* Spencer: modification to Haralds fix because macros are now renamed

* MME: don't assert on MAC failures of uplink NAS frames

Closes: #267

* MME: Avoid ogs_assert() in many situations

We don't want to crash the entire program just because a message
received from an external entity didn't match some of our expectations.

* compiles fine, checked DIFFs and only difference is the ogs_assert -> ogs_expect
