@lglhust

Is this reproducible? If so, how about using gdb?

$ git clone https://github.com/open5gs/open5gs
$ cd open5gs
$ git checkout v2.4.8
$ meson build --prefix=`pwd`/install
$ cd build
$ ninja install

And then, run the process using GDB.

$ gdb ./src/amf/open5gs-pcrf
...

Let me know if you have any other information.

Thanks a lot!

Hi acetcom：
I have met this problem twice yesterday, and the assert location is not same.
I'll try to test if it is reproducible. If i meet it again, i will provide more information as i can.
Thanks .

Here is the coredump output last time. The first one is what i post yesterday, but for the second i had not gotten the capture and the pcrf log.

The first one is：

Hi acetcom:

I tried several timers, i found the problem of “line 443 ogs_assert(new == 0) in pcrf_rx_send_asr()" to be reproducible.
The operation sequence is:
1、LTE UE A makes voice call to LTE UE B；
2、UE B accept the call;
3、UE A change to video call, and UE B accepts the video call;
4、The video call continues about 14 seconds，then UE B changes into voice call automatically without manual intervention;
-- I think the cause maybe the ims apn GBR (UL:128Kbps DL:128Kbps)is not enough for video call, so video call cannot be continued. In face, the GBR should be about 2Mbps for video call in fact.
5、UE A hung up the call；
6、Do step 1~5 repeatedly；
7、During the step 6，the call from UE A may not succeed.
8、Then the problem of “line 443 ogs_assert(new == 0)” may appear., just as i described in #1981.

Kindly, let me know if you need any other information.
Thanks a lot!

Hi acetcom:

There's an omission in pcrf_rx_str_cb() maybe:

out:
... ...
ogs_debug("[PCRF] Session-Termination-Answer");
if (sess_data)
state_cleanup(sess_data, NULL, NULL);

Thank you so much!

Merge main with test (#4)
175b475 
* Fix UL and DL URR Usage Report

* Follow-on up open5gs#1793

* [AMF] Fix for switching state when sending Deregistration Request fails

Provide pointer to state machine, instead of pointer to timer structure.
Bug was noticed when switching compiler optimization to -O2.

* [5GC] Fixed session deletion in a BSF (open5gs#1725)

* [UPF] test code for unspecified address (open5gs#1776)

* [Security] Fixed a crash for port scanning (open5gs#1767)

* Release v2.4.11

* Added Release Notes for v2.4.11

* [MME] Support for Insert Subscriber Data (open5gs#1794)

* [MME] Support for Insert Subscriber Data

* Supported AVPs in IDR will overwrite existing subscription information
* Provide error on partial APN updates
* IDR and ULA use same function to process AVPs
* Move subdatamask values into s6a, so both HSS and MME can use them
* Updates are not actioned at this time.  A Re-attach is required for
  most changes to take effect

* Memory issue on IDR exceptions

* Remove of handling MSIDSN change until DSR is used

* Follow-on up open5gs#1794

* [SBI] Client Request timeout

TS29.500
Ch 6.11 Detection and handling of late arriving requests

In Open5GS, this part was hard-corded.

HTTP2 Client sends a request and waits for 10 seconds.
If no response is received from the HTTP2 Server,
HTTP2 Client performs the exception handling.

In this commit, HTTP2 client sends Header with setting Max-Rsp-Time to 10 seconds.
However, HTTP2 server has not yet been implemented to process this value.
The server is still processing using hard-corded values (10 seconds).

* [MME] Cancel Location while Idle (open5gs#1797)

* Cancel Location while Idle Fix

* Forgot about SGSAP on MME Change.

Added "action" to sgsap_send_detach..

* Make handle_clr uniform with other handlers

* Added Robustness for Any Detach Type

* Memory wasn't freed upon CLR for unknown IMSIs

* Moving MME Detach to new PR

* Follow-up on open5gs#1797

* ogs_info swaps CP and UP SEIDs

* Follow-up on open5gs#1797

* fix dropped_dl_traffic_threshold ie.

* [AMF,UDM] Add support to subscribe to SDM changes

AMF subscribes to UDM for each registered UE.

At the moment, UDM does not send callback to AMF when any of the UE's
properties in the database changes.
At the moment, AMF does properly parse the ModificationNotification, but
does not do anything useful.

* [SMF] Update PFCP report error situation (open5gs#1819)

* Revert the previous commit on open5gs#1797

* Updated SBI module

- Introduced NF_INSTANCE_ID/NF_INSTANCE_TYPE
- Skip SCP in configuration validation

* [AMF] Increase size of TMSI pool

Each UE context has 'current' and 'next' TMSI values. AMF first
allocates the 'next' value, before confirming it and releasing the
'previous'. This means that we potentially need pool size of 2x the
amount of maximum configured UE.

Without this change, AMF would crash in case that there are 'x'
configured maximum amount of UE, and there are already 'x' registered
UE.

* [AMF] Reject registration requests when pool for UE contexts is empty

AMF does not crash anymore when a new UE registration request arrives,
and there is no available space left in UE context pool. Now it just
rejects the request with an error.

OpenAPI dictates that certain arrays should have at least one item,
otherwise they should not be present.
This includes lists for IPv4/v6 addresses, TAI/TAC lists, ...

Add a check if there is at least 1 item, before creating an array.
Also move variable declarations to inner blocks, to prevent some
accidental usage out of wanted scope.

* [AMF/MME] Added missing T3423 in conf (open5gs#1905)

* Fixed manual of sgwu.yaml conf

* [UPF] Fixed an infinte loop when ext_len is 0

* [SBI] Remove redundant code (open5gs#1923)

* [AMF] Wrongly sending PDU Session Release (open5gs#1925)

* [AMF] Fixed a crash while NGReset (open5gs#1928)

* amf: fix regression for smf selection

* free replybuf after sent replay message

* [SBI] Case-Insensitive inside MIME message (open5gs#1939)

* [UPF] Add metrics support

Expose metrics with labels according to ETSI TS 128 552 V16.13.0 in
UPF by using hash.

The metrics are named respecting the rule:
<generation>_<measurement_object_class>_<measurement_family_name>_<metric_name_as_in_TS_128_552>

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

* [PCF] Add metrics support

Expose metrics with labels according to ETSI TS 128 552 V16.13.0 in
PCF by using hash.

The metrics are named respecting the rule:
<generation>_<measurement_object_class>_<measurement_family_name>_<metric_name_as_in_TS_128_552>

Since slice itself is not unique, the plmnid label is exposed in
addition to snssai.

AM policy:
fivegs_pcffunction_pa_policyamassoreq and
fivegs_pcffunction_pa_policyamassosucc do not expose snssai label
since it is not available at the time of exposure.
plmnid is defined during AM policy processing, so not to lose the
difference to ...succ, the basic metric
fivegs_pcffunction_pa_policyamassoreq is preserved.

SM policy:
snssai is defined during SM policy processing, so not to lose the
difference to ...succ, the basic metric
fivegs_pcffunction_pa_policysmassoreq is preserved.

Those 2 basic metrics retain their position but are exposed with empty
labels.
Metrics with labels are called later, when the label values are known.

Exposed metrics example:
-standard counters:
fivegs_pcffunction_pa_policyamassoreq{plmnid=""} 3
fivegs_pcffunction_pa_policyamassoreq{plmnid="99970"} 3
fivegs_pcffunction_pa_policyamassosucc{plmnid="99970"} 3
fivegs_pcffunction_pa_policysmassoreq{plmnid="",snssai=""} 3
fivegs_pcffunction_pa_policysmassoreq{plmnid="99970",snssai="1000009"} 3
fivegs_pcffunction_pa_policysmassosucc{plmnid="99970",snssai="1000009"} 3

-nonstandard gauge (added for controlling purposes -
same metric as existing metric on AMF and SMF):
fivegs_pcffunction_pa_sessionnbr{plmnid="99970",snssai="1000009"} 0

* Follow-up on open5gs#1940

* Follow-up on open5gs#1940 - Fixed compile error

* [SMF] fix crash due free-ing invalid pointer

In case that database is (manually) corrupted for a specific UE, SSC
mode and ARP preemption vulnerability fields are not set correctly,
SMF will crash when trying to build a request to create PCF association.

Function smf_npcf_smpolicycontrol_build_create() will end prematurely,
and when cleaning up resources it will try to free() up invalid pointer,
which was not set to 0 at beginning of the function.

* [AMF] Add RM metrics support

Expose RM metrics with labels according to ETSI TS 128 552 V16.13.0 in
AMF by using hash.

The metrics are named respecting the rule:
<generation>_<measurement_object_class>_<measurement_family_name>_<metric_name_as_in_TS_128_552>

Since slice itself is not unique, the plmnid label is exposed in
addition to snssai.

RegInitFail is exposed as an alternative to RegInitReq and RegInitSucc
counters so cause label can be provided. It counts rejected registrations
and rejected authentications.
Rejected authentications are counted under label cause="0".

Exposed metrics example:
-standard gauge:
fivegs_amffunction_rm_registeredsubnbr{plmnid="00101",snssai="1000009"} 1

-nonstandard counter:
fivegs_amffunction_rm_reginitfail{cause="3"} 4

* [SMF] Add SM metrics support

Expose SM metrics with labels according to ETSI TS 128 552 V16.13.0 in
SMF by using hash.

The metrics are named respecting the rule:
<generation>_<measurement_object_class>_<measurement_family_name>_<metric_name_as_in_TS_128_552>
Existing gauge sessions_active is renamed!

Since slice itself is not unique, the plmnid label is exposed in
addition to snssai.

Exposed metrics example:
-standard gauges:
fivegs_smffunction_sm_sessionnbr{plmnid="00101",snssai="1000009"} 0
fivegs_smffunction_sm_qos_flow_nbr{plmnid="00101",snssai="1000009",fiveqi="9"} 0

* Update document

* Update document

* Add NF load to NRF Heartbeat

The current load percentage of the NF Service Consumer is provided
in the payload body of the PATCH request when periodically
contacting the NRF (heart-beat).

AMF: ratio between currently connected ran_ue and maximum number of them
SMF: ratio between current PDU sessions and maximum available
PCF: ratio between current AM+SM policy associations and maximum available
     or ratio between currently connected UEs and maximum number of them
     (the load which is higher)
AUSF, UDM: ratio between currently connected UE and maximum number of them
BSF: ratio between current sessions and maximum available
NSSF: ratio between currently used NSIs and maximum number of them

NRF currently doesn't determine that the NF Profile has changed.

* [SMF] Fix metric bearers_active

Metric 'bearers_active' was incremented in only one code path
(smf_bearer_add() for 4G only), while it was decremented from two paths
(smf_bearer_remove() for both 4G and 5G).
Increment metric also for 5G path (smf_qos_flow_add()), so it won't get
decremented into negative values.

* [mongo] Use "ping" command instead of "serverStatus"

"serverStatus" on the "admin" database may fail due to insufficient privileges.

* Introduced Subscription identifier de-concealing

* [Gx/Gy] MAX_CC_REQUESTER_NUMBER(32->64) (open5gs#2038)

Incrased MAX_CC_REQUESTER_NUMBER from 32 to 64

* [NF] Fix double-free crash when NF is under heavy load

<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.

TS33.401
7 Security procedures between UE and EPS access network elements
7.2 Handling of user-related keys in E-UTRAN
7.2.7 Key handling for the TAU procedure when registered in E-UTRAN

If the "active flag" is set in the TAU request message or
the MME chooses to establish radio bearers when there is pending downlink
UP data or pending downlink signalling, radio bearers will be established
as part of the TAU procedure and a KeNB derivation is necessary.

This is in line with the implementation with microhttpd server
(mhd-server.c).

* [SBI] Fix possible crash when handling PatchItems in NFProfile PATCH req

* Follow-up on open5gs#2069

* [DOCS] Removed missing link

* Further Follow-up on open5gs#2063
