2024-01-20gsup: Convert PDP-Type IE to PDP-Address IEPau Espin Pedrol1-3/+6
The previous PDP-Type IE should have been a PDP-Address from the start, since having only PDP-Type with no address is only a specific case (dynamic addressing). This becomes clear by looking at other similar protocols like: * MAP: APN-Configuration IE has servedPartyIP-IP{v4,v6}-Address IEs * Diameter S6b, 3GPP TS 29.272 7.3.35 APN-Configuration contains Served-Party-IP-Address AVPs * Diameter SWx, 3GPP TS 29.273 APN-Configuration. * GTPv1C Ts 29.060 7.7.29 PDP Context containing PDP Address. Since PDP-Type on its own really makes no sense, being it a special case of PDP-Address, let's keep the IE by renaming it (keeping old name too for API backward compat) and extend it to support lengths > 2 bytes. Old implementation of libosmogsm gsup actually ignored lengths > 2 bytes, so we are safe acting against older implementations here, both on the sending and receiving side on the wire. The big drawback of this commit is that it breaks ABI compatibility due to adding "struct osmo_sockaddr pdp_address[2];" to struct osmo_gsup_pdp_info, which in turn affects shift of fields in struct osmo_gsup_message. Unfortunately, there's not much that can be done to improve the situation when adding the missing field, due to existing API having the same struct for all messages. Ideally we'd have 1 union with structs per message type inside, this way the ABI break would be far less pronounced. The GSUP test output change is becaue we now accept some of the len>2 cases for PDP-Type/Address IE which were being rejected since a couple commits ago. libosmogsm gsup code is now disabled in EMBEDDED mode, since it nows depends on core/socket.h (struct osmo_sockaddr) which is not available in EMBEDDED, and hence fails during build: """ In file included from /build/include/osmocom/gsm/gsup.h:45, from /build/src/gsm/gsup_sms.c:28: /build/include/osmocom/core/socket.h:15:10: fatal error: arpa/inet.h: No such file or directory 15 | #include <arpa/inet.h> | ^~~~~~~~~~~~~ """ Related: OS#6091 Change-Id: I775ff9c3be165d9f30d6ab55d03f99b6104eadd6

RTS based polling in LAPDm code is disabled by default. Make libosmogsm stay compatible with existing applications that do not use RTS based polling.

2023-11-27LAPDm: Add an extra queue for UI framesAndreas Eversberg1-0/+1

2023-11-27LAPDm: Add support for RTS based pollingAndreas Eversberg1-0/+8
The lower layer must set the 'POLLING_ONLY' flag and provide frame number when polling a frame. If T200 is pending, it is started with a timeout frame number in advance to given frame number. The lower layer must call lapdm_t200_fn() after a frame has been received or if a frame has not been received. Also it must be called after a TCH frame has been received. LAPDm uses this to check the T200 timeout condition. A new function is used to set the frame number based timeout values. Related: OS#4074 Change-Id: I6ebe83f829d7751ea9de1d90eb478c7a628db64c

2023-08-21lapdm: Append RSL_IE_OSMO_ABS_FRAME_NUMBER to RSLms msgs towards upper layersPau Espin Pedrol1-0/+2
This makes it possible to track GSM time in the upper layers. The existing RSL_IE_FRAME_NUMBER and RSL_IE_STARTNG_TIME cannot be used there, since those are 16bit fields containing Relative FN values. The IE needs to be added before the L3_INFO one, because user code usually assumes the msgb->l3 pointing to L3_INFO value extends until the end of the message, using msgb3_len(msg). Regarding having an extra IE at the middle, it's not a big problem since the libosmocore version submitting this commit to the upper layers is the same which will also be parsing it through rsl_tlv_parse() later on by the app. Related: OS#3626 Change-Id: Id62c18f49f270449067b25b7104eb8b47f1955ec

2023-08-11lapdm: Track fn of primitives in struct lapdm_msg_ctxPau Espin Pedrol1-0/+1
This field will be used in follow-up commits to provide FN information in RSLms primitives towars upper layers. This is needed for instance on the MS side when a CCCH_DATA.ind is received containing a TBF ImmAss with a relative FN indicating the Starting Time. Without tracking FN advance, the uppers layers are not capable of figuring out the absolute FN of the TBF Starting time. The struct lapdm_msg_ctx is not really used outside of libosmocore, so we are safe extending it. Related: OS#3626 Change-Id: Icf986f4202703eb452bedc1b749bb8ce0c73706f

As per 3GPP TS 48.008, section 3.2.2.103, the "Codec Type" field may contain either a certain 3GPP Speech Codec Type directly (4 bit value), or the so called "Codec Extension" = 0xFh, in which case the real Codec Type follows in the next octet as "Extended Codec Type". CSD is such an example, the encoding is defined as follows: 8 7 6 5 4 3 2 1 +----+----+----+----+-------------------+ | -- | PI | PT | -- | 0xFh | +----+----+----+----+-------------------+ | Extended Codec Type (CSData) | +----+----+-----------------------------+ | R2 | R3 | | +----+----+-----------------------------+ CSData is coded with 0xFDh or '1111 1101' (0xfd). Let's have the "Codec Extension" value clearly defined in the header file, but intentionally separate from the other GSM0808_SCT_* values.

2023-06-08improve API for osmo_routing_area_idNeels Hofmeyr1-1/+6
Code review for [1] has asked for providing proper API for struct osmo_routing_area_id. For historical reasons, we have struct gprs_ra_id and struct osmo_routing_area_id serving the exact same purpose: represent a decoded 3GPP TS 24.008 § 10.5.5.15 Routing area identification. The "better" one is struct osmo_routing_area_id: it allows using API like osmo_plmn_cmp(), because it is made up of meaningful sub-structs. Implement de/coding using the functions already available for the sub-struct osmo_location_area_id, and simply add the RAC. Add a test in gsm0408_test.c. Note that other utility functions are already available for struct osmo_routing_area_id: osmo_rai_name2(), osmo_rai_cmp(). There is no real need to deprecate struct gprs_ra_id, because there is not really anything wrong with it. It just isn't as well integrated with other utility API as struct osmo_routing_area_id is. Just add comments.
