currently if no IP address is available from the configured
subnets in the SMF when attempting to assign an IP to an UE
we assert and the SMF crashes. Handle the error more gracefully
by returning an error cause instead.
Open5GS documentation instructs to install into open5gs.git/install/
during build [1]:
"""
$ cd open5gs
$ meson build --prefix=`pwd`/install
$ ninja -C build
"""
As a result, this directory appears all the time when using git, since
it's not in the .gitignore file. Add it.

Error executing command, exiting
After the page remains inactive for 10 minutes,
clicking on the edit page will result in a blank screen
when you click on edit after 10 minutes,
all user data is lost. After capturing the network packets,
it can be observed that the frontend sends a fresh request
to the backend for data, and the backend responds correctly,
but the page does not refresh correctly.
`function recent(fetchedAt) {
if (fetchedAt === null) return false;
const interval = 10 * 60 * 1000; // 10 minutes
return ((Date.now() - interval) < fetchedAt);

The crash is caused by ogs_assert(data) in listEntry_create(void *data).
Reason for the failing assertion is that in
OpenAPI_subscription_data_t *OpenAPI_subscription_data_parseFromJSON(
cJSON *subscription_dataJSON)
in line 501 of file subscription_data.c the event string is transformed
into an integer/enum value, which in case of an unknown event is 0.
Steps to reproduce:
1. Deploy NRF
2. Run curl --http2-prior-knowledge --header "Content-Type: application/json" --data '{"nfStatusNotificationUri": "test@example.com", "reqNotifEvents": ["unknown"], "subscriptionId": "12345"}' "http://<NRF_IP>:<NRF_PORT>/nnrf-nfm/v1/subscriptions"
There was a memory problem in the encryption using snow_3g_f8,
so AMF/MME crashed.
To solve this problem, we used the snow-3g encryption library
created as below.
https://github.com/rcatolino/libressl-snow3g
However, it seems that this library cannot be used to create
integrity hash like snow_3g_f8.
So, we decided to keep both snow-3g libraries for the time being.
1. lib/crypt/snow3g* : for INTEGRITY (NIA1, EIA1)
2. lib/crypt/openssl/snow3g* : for ENCRYPTION (NEA1, EEA1)
Scenario is handover on S1AP, data forwarding is enabled, and
the Source ENB is forwarding DL PDCP packets to EPC(SGWU)
with PDCP SN included. SGWU is also forwarding these packets
to the Target ENB.
However the PDCP SN is not present in the forwarded packets
from SGWU to Target ENB.
I modified this part, and there was the same problem in 5GC, fixed it as well.
A lot of code in GTP-U has been modified,
so if you have any problems, please let us know right away.
curl --noproxy '*' --http2-prior-knowledge -X POST --header "Content-Type: multipart/related" --data-binary @pdu http:/192.168.29.231:7777/nsmf-pdusession/v1/sm-contexts

SMF crashes as not able to decode the message properly. SmContextCreateData is not accessible.
After examining the call stack and reading the source code, I found that
in /lib/core/ogs-pool.h line 152: (pool)->array[i] = i+1;
then in lib/pfcp/context.c line 78: pdr_random_to_index[ogs_pfcp_pdr_teid_pool.array[i]] = i;
ogs_pfcp_pdr_teid_pool.array[i] may exceed the size of pdr_random_to_index, leading to a heap-buffer-overflow.
Modifications were made to resolve the following assertion..
Invalid HNET PKI Value [0] (../lib/sbi/conv.c:135)
ogs_supi_from_supi_or_suci: Expectation `supi' failed. (../lib/sbi/conv.c:262)
udm_ue_add: Assertion `udm_ue->supi' failed. (../src/udm/context.c:144)
backtrace() returned 8 addresses (../lib/core/ogs-abort.c:37)
A situation in which you establish two sessions and release both of them.
In the first SESSION, the UE normally sent PDUSessionResourceReleaseResponse
and PDU session release complete. However, these were not sent when releasing
the second SESSION.
At this point, when the UE tried to do a deregistration,
the SMF was not properly handling the exception.
I've just fixed this.
After the UE performs Registration/Attach, SQN field is created.
If we edit subscriber information when SQN value is present, WebUI crash occurs.
It is because the way to handle Long Type(SQN:Long) is different
when the mongoose version is 6 or higher.
To avoid this crash, we use the mongoose version down to 5.x first.
Whether or not to send a Setting ACK is determined by the nghttp2 library.
Therefore, when nghttp2 informs us that it want to send an SETTING frame
with ACK by nghttp2_session_want_write(), we need to call session_send()
directly to send it.
NAS, GTP, PFCP, SBI, all except S1AP/NGAP use x1000 multiplier for Kbps, Mbps, Gbps ... etc.
From now on in WebUI all units also use a multiplier of x1000.
