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 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.
