Previously, malformed Protocol Configuration Options (PCO) data would trigger
ogs_assert failures in both the generic parser and SMF build routines,
causing the SMF process to abort unconditionally.
This commit replaces those fatal assertions with conditional checks:
In ogs_pco_parse(), switch from ogs_assert(size == data_len) to
ogs_expect(size == data_len), allowing the function to return gracefully.
In SMF's PCO build (smf_pco_build) and all downstream build paths
(including GN, GSM, S5C modules), replace ogs_assert(pco_len > 0)
with explicit if (pco_len <= 0) checks that:
Ensure that malformed or incomplete PCOs no longer crash the process,
but instead are handled cleanly so the network function can continue operating.
Previously, policies were configured via YAML files without MongoDB.
This update enhances the YAML approach by adding the 'supi_range' key to
filter policies based on UE SUPI ranges. When both 'supi_range' and
'plmn_id' are provided, both conditions must be met.
Note that PLMN-ID filtering will be deprecated in a future release.
Implement Control Message handling between V-SMF and H-SMF
during Home Routed Roaming process
Completed the implementation of control messages exchanged
between V-SMF and H-SMF as part of the Home Routed Roaming process
The osmocom ttcn3-mme-ogs test uses an APN consisting simply of the NULL
byte. This corresponds to one label of length zero, so simply the APN "".
Since commit 333d3fe1 ogs_fqdn_parse() returning zero is considered an
error in ogs_gtp1_parse_pdp_context().
Fix this by returning a negative value on error in ogs_fqdn_parse() and checking for
that.
o Generate the private key as below.
$ openssl genpkey -algorithm X25519 -out /etc/open5gs/hnet/curve25519-1.key
$ openssl ecparam -name prime256v1 -genkey -conv_form compressed -out /etc/open5gs/hnet/secp256r1-2.key
o The private and public keys can be viewed with the command.
The public key is used when creating the SIM.

* Introduce Cancel Location and Insert Subscriber Data features to HSS.
* HSS database will keep track of last known MME and Update Time
* Purged UE flag is established in HSS for future PUR handling
* HSS Thread will connect to database and watch change stream
mongoDB must be configured with a Replica Set to use this
* HSS will send IDR if subscription data changes
* HSS will send CLR to old MME if MME host or realm changes
* Function created to allow ULA and IDR to generate Subscription-Data AVP
* MME Hostname and Realm shown in WebUI
* Resolve freeDiameter errors
During a ULR, if database does not contain a last known MME, a CLR is being sent to a Null destination. This will ensure that a destination is available in the database before sending the CLR.
* Removed change streams. Added PUR handling.
* newline needed at end of file.
* Removed temp variable.
* * Change WebUI to 2x2 display
* Including UE Purged indicator
* Using pointers in ogs_subscription_data_t
* better memory mangement with pointers
* Tweak to Destination used by hss_s6a_send_idr to use last known MME
* Check for null mme_host and mme_realms
Do this before trying to compare the strings.
