This reverts commit 54b1b3be37ae863ddbdd2b9408ebdd98ac8470d8. osmo-bts is forwarding the msgbs as they come from lapdm to the RSL on the wire, which means we end up sending the osmocom-specific IEs on the wire, something which was not envisioned when adding this IE.

2023-08-21rsl: Introduce new osmocom extension IE RSL_IE_OSMO_ABS_FRAME_NUMBERPau Espin Pedrol1-0/+1
This will be used in RSLms to provide Absolute Frame Number information of the primitive indications being sent to upper layers, so that it's 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.

2023-07-25gsm_08_08: define GSM0808_SCT_EXT (separately)Vadim Yanitskiy1-0/+6
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.

2023-03-22Fix parsing of TLV_TYPE_SINGLE_TVPau Espin Pedrol1-5/+10
The decoding path of TLV_TYPE_SINGLE_TV is wrong, since it is not shifting right the tag before using it. On the other hand, the encoding path (tlv_encode_one) is doing that, so it is clear there's a bug. It seems that in order to workaround the bug some IEs in gsm_04_08.h (TS 24.008 and TS 44.018) were defined incorrectly (eg 0x80) while the spec clearly assigns eg. "8" to it, and makes sure no full byte IEI collides. Some other IEIs like GSM48_IE_GMM_CIPH_CKSN which are also of the same type were already correctly defined as 0x08.

2023-02-20Move libosmogsm TS 44.060 declarations under include/osmocom/gsm/Pau Espin Pedrol2-0/+253
Currently there's a big mess where include dir osmocom/gprs/ is used by both libosmogsm and libosmogb. Most of the header files under osmocom/gprs/ are actually all the headers of libosmogb (there's no osmocom/gb/ dir). But a couple files are actually RLC/MAC (TS 44.060) related are are also stored in there. Those files have no relation/use in Gb, and are actually interused with GSM (eg System Information 13 Rest Octets). Hence, it makes sense to have the RLC/MAC related parts inside osmocom/gsm/ as they should be in libosmogsm (and they actually are, see gprs_rlc.h function implemented in src/gsm/gsm48_rest_octets.c). The fact that some libosmogsm headers were placed in osmocom/gprs instead of osmocom/gsm already created some issues, like libosmocore.spec.in putting "%_includedir/%name/osmocom/gprs/" under libosmogb, which is wrong. As a first step to fix the mess, we move the 2 RLC/MAC headers currently under osmocom/gprs/{gprs_rlc,protocol/gsm_04_60}.h under a single header gsm/protocol/gsm_44_060.h The two old headers are left existing for backward compatibility and now simply include the new libosmogsm header, plus a warning asking users to switch to the new header so we can eventually get rid of them. This means libosmogb depends on libosmogsm, which is fine and was already the case beforehand (libosmogb using functions like gsm48_encode_ra() and linking against it in src/gb/Makefile.am).
