Based on the standard document below, when the UE is in the IDLE state,
we checked the implicit timer and tried to send a message to the UE,
but it doesn't work properly.
So, first of all, I deleted the related code.
- TS 24.301 Ch 5.3.7
If ISR is not activated, the network behaviour upon expiry of
the mobile reachable timer is network dependent, but typically
the network stops sending paging messages to the UE on the
first expiry, and may take other appropriate actions
- TS 24.501 Ch 5.3.7
The network behaviour upon expiry of the mobile reachable timer is network dependent,
but typically the network stops sending paging messages to the UE on the first expiry,
and may take other appropriate actions.
Move the config to the sgsn node instead of having a specific route with
specific format "default: route", since anyway internally it's already
applied to the sgsn object.
When AMF release the NAS signalling connection,
ran_ue context is removed by ran_ue_remove() and
amf_ue/ran_ue is de-associated by amf_ue_deassociate().
In this case, implicit deregistration is attempted
by the mobile reachable timer according to the standard document,
and amf_ue will be removed by amf_ue_remove().
TS 24.501
5.3.7 Handling of the periodic registration update timer and
Start AMF_TIMER_MOBILE_REACHABLE
mobile reachable timer
The network supervises the periodic registration update procedure
of the UE by means of the mobile reachable timer.
If the UE is not registered for emergency services,
the mobile reachable timer shall be longer than the value of timer
T3512. In this case, by default, the mobile reachable timer is
4 minutes greater than the value of timer T3512.
The mobile reachable timer shall be reset and started with the
value as indicated above, when the AMF releases the NAS signalling
connection for the UE.
The 'data' struct used to specify the diameter dispatch options for the
MME callbacks was not being initialized properly, which meant that the
App id could contain garbage. This was preventing the callbacks from
being invoked when receiving ISD/CLR requests.
Each SMF's NfProfile can contain multiple SmfInfo items. The issue was
that AMF checked only the first SmfInfo for correct S-NSSAI/NR-TAI
information.
In case of a 5G core setup with SMF handling 2 or more slices, and UE
trying to establish multiple PDU sessions, AMF would report an error
when trying to find the correct serving SMF.
[amf] ERROR: [1:0] (NF discover) No [nsmf-pdusession] (../src/amf/nnrf-handler.c:85)
Since [redesign](8553c77733)
of fivegs_smffunction_sm_sessionnbr gauge, the metric doesn't
expose some decrements. The decreasing of gauge had been
moved out of function stats_remove_smf_session.
It should be decreased every time stats_remove_smf_session
is called, but this particular case is easily reproducible
by killing UPF while the session is established.
The current code uses the cc request number as an index to the
transaction array (xact/xact_data). Since cc request number is a 32 bit
integer this is unfeasible for longer sessions and if more than a
handful of messages are exchanged per session.
The array size was already increased in #2038 which simply delays the
issue.
Furthermore, the current code asserts that cc_request_number is <=
MAX_CC_REQUEST_NUMBER which leads to an out-of-bounds write if
cc_request_number == MAX_CC_REQUEST_NUMBER.
Instead use a smaller array and index into it using cc_request_number
% array size. More than 2 requests should never be in flight at any one
time (initial or update request together with a termination request) so
an array size of 4 should be fine.
- have a more consistent naming among the NF's
- always have the same prefix (amf_/smf_/pcf_) depending on the NF
- function name is always the same, how the function calculates the load
is NF specific and internal to the function itself (but not the function
name).
- the 'if' clause was comparing some value with an always '1' due to
wrong calculation. Consequently, this 'if' statement never executed.
- sizes for session pool and UE pools are directly linked between each
other. We need to count the number of items only in one of the pools to
correctly represent the NF load
- if anything, we should also check the load of the application pool to
determine correct load of the NF
ogs_pool_init() shall be used in the initialization routine.
Otherwise, memory will be fragment since this function uses system malloc()
Compared with ogs_pool_init()
ogs_pool_create() could be called while the process is running,
so this function should use ogs_malloc() instead of system malloc()

Registration type label is not provided.
A nonstandard PLMNID label is added to achieve uniqueness.
- 5.3.1.3 Number of PDU sessions requested to be created by the SMF
PLMNID and SNSSAI are defined during PDU session creation processing.
Some requests can be rejected during processing before label values are known.
Those requests are not counted under particular labels.
To count also such requests, the basic metric with empty labels is exposed too.

- 5.3.1.5 Number of PDU sessions failed to be created by the SMF
```
fivegs_smffunction_sm_pdusessioncreationfail{cause="400"} 1

Example for one successful and one failed (during creation processing) PDU session creation:
```

```
After N2 Handover (1 AMF, multiple gNB's) was successfully executed, the
PDU session was not properly released afterwards on PDU Session Release
Request from UE.
The reason was that after N2 Handover the new 'ran_ue' context did not
have any information about the active PDU sessions.
Copy the information about PDU sessions from old ran_ue context to the
new one.

Follow-up on [#2048](https://github.com/open5gs/open5gs/pull/2048)
AMF crashes when 'skipInd' field is missing:
```
amf | 03/21 07:45:04.092: [amf] FATAL: [imsi-001010000000000] No skipInd (../src/amf/namf-handler.c:392)

```
In case of CM_CONNECTED skipInd is not important.
In case of CM_IDLE the proper relase would contain skipInd.
SMF already handles the freeing in labels correctly.
In the same manner the memsets are moved to the beginning of the
problematic functions in AMF and PCF.
When UDM issues a SDM Data Change Notification with request to modify
RAT restrictions, AMF would crash when it tried to send a SDM
subscription delete as part of Network Initiated Deregistration.
Function amf_ue_sbi_discover_and_send() changed from returning boolean,
to returning integer (one of OGS_OK/OGS_ERROR/...).
When both IPv4 and IPv6 Frame Routes are set, IPv4 Frame Route list
was subsequently cleared.
When UE tried to deregister, PCF would crash when it tried to free the
Frame Routing list.
POST requests to {apiRoot}/nnrf-nfm/v1/subscriptions return
a HTTP Location header in 201 respose
in the form {apiRoot}/nnrf-nfm/v1/subscriptions/{subscriptionID}
In case that handling Service Request results in an error, AMF sends a
Service Reject and sets UE's context to exception state. Without the
'break', the code would set UE's context to registered state.

<nf>/init.c:<nf>_main() :
ogs_pollset_poll() receives the time of the expiration of next timer as
an argument. If this timeout is in very near future (1 millisecond),
and if there are multiple events that need to be processed by
ogs_pollset_poll(), these could take more than 1 millisecond for
processing, resulting in the timer already passed the expiration.
In case that another NF is under heavy load and responds to an SBI
request with some delay of a few seconds, it can happen that
ogs_pollset_poll() adds SBI responses to the event list for further
processing, then ogs_timer_mgr_expire() is called which will add an
additional event for timer expiration. When all events are processed
one-by-one, the SBI xact would get deleted twice in a row, resulting in
a crash.

5qi is not available in UPF.
To present 5qi to the user, MN will have to maintain a table qfi->5qi
for each QoS flow (will have to get information from SMF).
So UPF has to expose qfi. qfi itself is not useful. When used, UPF will
have to expose additional label to define the session (e.g. source
interface).
Label dnn is set to value of APN/DNN received in Establishment.
Since SMF does not add APN/DNN to Establishment, the label is empty.
When APN/DNN will be set by SMF, it should be added to sess in UPF
and used in metrics on Modification and Deletion.
Both datavolumeqosleveln3upf are exposed in bytes.
MN is providing the transformation to kbits.
fivegs_upffunction_upf_qosflows should expose the number of QFIs used in
sessions, but exposes number of QER rules, which is currently equal to
QFIs.
The label snsssai is not provided since the slice is not available on UPF.
Exposed metrics example:
Standard counters:
fivegs_ep_n3_gtp_indatapktn3upf 28637
fivegs_ep_n3_gtp_outdatapktn3upf 14729
fivegs_upffunction_sm_n4sessionestabreq 4

fivegs_ep_n3_gtp_outdatavolumeqosleveln3upf{qfi="1"} 737548
Nonstandard gauge (added for controlling purposes -
same metric as existing metric on AMF and SMF):
fivegs_upffunction_upf_sessionnbr 1
Standard gauge:
fivegs_upffunction_upf_qosflows{dnn=""} 1
Even if the configured log level for the application was set to "error",
the first "info" message of the metrics library was output to the log.
Reorder the initialization of the metrics library.
Support for change stream is only available in mongoc >=1.9.0
- Disabled related functions in dbi.
Support for bson to json used in debug statement only in libbson >=1.7.0
- Simple debug message in lower versions
