[SMF] Introduce optional Gy interface support (#1479) The use of the Gy interface (SMF acting as CTF towards an OCS node) is mandated through configuration file. Default value "enable: auto" will only make use of it in case a Diameter peer announcing support for the Credit-Control Application is found. Upon subscriber session creation, and after auth check over Gx, the SMF will create a Gy session with the OCS and only after that step the SMF will accept the session back to the subscriber. The OCS may then grant some traffic volumes/time and ask to be notified back with updated measurements. In order to get the measurements, the SMF relies on PFCP URR configured to the UPF through Session Repoort Request messages. When closing the subscriber session, the SMF will also terminate the Gy session at the OCS. So far only some specifics parts of the Gy interface as well as the PFCP side are implemented. Those should be enough to at least have volume/time thresholds granted by the OCS, which then will be able to track subsriber resource use. This patch doesn't implement the OCS side of the Gy interface, that's left as a future exercise. The interface was tested using an OCS emulator implemented in TTCN-3 [1] [1] https://cgit.osmocom.org/osmo-ttcn3-hacks/

[SMF] Introduce optional Gy interface support (#1479) The use of the Gy interface (SMF acting as CTF towards an OCS node) is mandated through configuration file. Default value "enable: auto" will only make use of it in case a Diameter peer announcing support for the Credit-Control Application is found. Upon subscriber session creation, and after auth check over Gx, the SMF will create a Gy session with the OCS and only after that step the SMF will accept the session back to the subscriber. The OCS may then grant some traffic volumes/time and ask to be notified back with updated measurements. In order to get the measurements, the SMF relies on PFCP URR configured to the UPF through Session Repoort Request messages. When closing the subscriber session, the SMF will also terminate the Gy session at the OCS. So far only some specifics parts of the Gy interface as well as the PFCP side are implemented. Those should be enough to at least have volume/time thresholds granted by the OCS, which then will be able to track subsriber resource use. This patch doesn't implement the OCS side of the Gy interface, that's left as a future exercise. The interface was tested using an OCS emulator implemented in TTCN-3 [1] [1] https://cgit.osmocom.org/osmo-ttcn3-hacks/

Introduce Gn interface (GTPv1C) Support to PGW (#1351) * [CORE] tlv: Store mode in ogs_tlv_t This allows specifying the format of the IE for each individual IE, hence allowing messages containing IEs formatted in different ways. This is needed in order to support parsing GTPv1-C, since messages contain IEs with different structure (TLV vs TV). Hence, this is a preparation patch to add support for parsing TVs in ogs-tlv.c/.h. * [CORE] tlv: Support parsing msg with both TLV and TV in it IEs of type TV are sometimes used in GTPv1-C. Current tlv parser/builder doesn't provide with ways to parse messages which contain TV formatted IEs. This patch adds the relevant types and ways to encode/decode them. Furthermore, the current parser/builder allows parsing/building messages containing the exact same format in all its IEs. A new parser function is added which allows parsing messages of different types (TV, TLV) mixed in the same message. In order to be able to do so, it uses the general msg_mode passed to it in order to know the general TLV format (in essence, the length of the Tag field, and also the length of the Length field if applicable each IE). Looking up the instance in the TLV description is left undone and hadcoded to 0, since the only user so far requiring this API is GTPv1-C, which has no instances. * [CORE] tlv: Support repeated tag+instance parsing TLV message In GTPv2C, repeated IEs (same tag) are easily differentiated by the Instance byte, which provides info to match different decoded structures. In GTPv1C though, there's no Instance byte, and we still encounter repeated IEs (like GSN Address in Create PDP Context Request). Hence, the TLV decoder needs to be updated to track count of IEs found (identified by tag+instance, where instance is always 0 in GTPv1C) and get the proper description index + offset into the decoded structure. * [GTP]: Move GTPv2-C specifics to its own libgtp subdir This will allow adding GTPv1-C code by the side. Most GTPv2 code is left in this patch as "gtp" instead of renaming it to "gtp2" in order to avoid massive changes. It can be done at a later stage if wanted. * [GTP] Support generating GTPv1-C messages * [SMF] Add Gn interface support This patch introduces GTPv1C support to open5gs-smfd. With it, open5gs-becomes a GGSN too, where SGSN can connect to, hence supporting GERAN and UTRAN networks.

Introduce Gn interface (GTPv1C) Support to PGW (#1351) * [CORE] tlv: Store mode in ogs_tlv_t This allows specifying the format of the IE for each individual IE, hence allowing messages containing IEs formatted in different ways. This is needed in order to support parsing GTPv1-C, since messages contain IEs with different structure (TLV vs TV). Hence, this is a preparation patch to add support for parsing TVs in ogs-tlv.c/.h. * [CORE] tlv: Support parsing msg with both TLV and TV in it IEs of type TV are sometimes used in GTPv1-C. Current tlv parser/builder doesn't provide with ways to parse messages which contain TV formatted IEs. This patch adds the relevant types and ways to encode/decode them. Furthermore, the current parser/builder allows parsing/building messages containing the exact same format in all its IEs. A new parser function is added which allows parsing messages of different types (TV, TLV) mixed in the same message. In order to be able to do so, it uses the general msg_mode passed to it in order to know the general TLV format (in essence, the length of the Tag field, and also the length of the Length field if applicable each IE). Looking up the instance in the TLV description is left undone and hadcoded to 0, since the only user so far requiring this API is GTPv1-C, which has no instances. * [CORE] tlv: Support repeated tag+instance parsing TLV message In GTPv2C, repeated IEs (same tag) are easily differentiated by the Instance byte, which provides info to match different decoded structures.

fix: DRB lost issue when additional TFTs needs to be added to existing bearer with TFTs This commit address the issue where a bearer with particular PCC rule name exists with TFTs and addtional TFTs needs to be added to same bearer and DRB lost is reported by UE. This is achieved by creating EPS Bearer Level Traffic Flow Template with TFT operation code as 'OGS_GTP_TFT_CODE_ADD_PACKET_FILTERS_TO_EXISTING_TFT' in above scenario rather than use 'OGS_GTP_TFT_CODE_CREATE_NEW_TFT' at all times. And, not remove existing packet filters for the bearer.
