2018-04-17protocol/gsm_04_08.h: drop incorrect GSM48_PDISC_USSDVadim Yanitskiy1-1/+0
According to the GSM TS 04.07, section 11.2.3.1.1 "Protocol discriminator", bits 1 to 4 of the first octet of a standard L3 message contain the protocol discriminator IE. Meanwhile, the GSM48_PDISC_USSD represents value 0x11, i.e. 0b10001, that requires 5 bits, and moreover it is not documented anywhere. Let's drop it.

2018-04-09add gsm48_reject_value_namesNeels Hofmeyr1-0/+4
There seems to be quite some confusion / overlap between enum gsm48_reject_value, gsm48_gsm_cause and gsm48_gmm_cause. I tried to go with gsm48_gsm_cause_names[], but e.g. GSM48_REJECT_CONGESTION is not represented. Instead of attempting to mix/merge those enums, provide a separate value string array for enum gsm48_reject_value. This will be used by osmo-msc's libvlr (refactoring of FSM result handling), I27bf8d68737ff1f8dc6d11fb1eac3d391aab0cb1. Change-Id: I6661f139e68a498fb1bef10c266c2f064b72774a

2018-02-03gsm48_hdr_msg_type[_r99]: Fix bit-masksHarald Welte1-2/+2
TS 24.007 is quite clear: The upper two bits of the message type octet are *not* part of the message type in any of the L3 protocols which implement sequence numbers. it doesn't matter if it's R98 or R99, or whether the sequence number is 1bit or 2bits wide.

2017-06-23doxygen: unify use of \file across the boardNeels Hofmeyr1-1/+3
Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

2017-03-16add gsm48_pdisc_msgtype_name()Neels Hofmeyr1-0/+5
Composing the message type string requires knowing the protocol discriminator. To ease printing the message type, add this function to switch between the defined value_string[]s depending on pdisc. Also publish the message type value_string[]s -- without inline functions to access them because it is anyway more convenient to use gsm48_pdisc_msgtype_name() instead. Since gsm48_pdisc_msgtype_name() is nontrivial, do not add as inline function -- in case the message type is not known, it needs a static string buffer.

2017-03-16add gsm48_pdisc_names and gsm48_pdisc_name()Neels Hofmeyr1-0/+4

2017-03-14gsm0408: add chreq_type for CHREQ_T_PDCH_ONE_PHASE and CHREQ_T_PDCH_TWO_PHASEAlexander Couzens1-0/+2
The previous version of this commit got reverted to avoid a breakage in openbsc. The problem is openbsc use an array of chreq_type with a manual defined size. This array is using enums as index which breaks if any elements got added into the middle, because the size of the array can't hold elements greater or equal than the size.

2017-02-23gsm_04_08.h: add R99 MSCR and CBQ3 to SI3 Ctrl Chan DescrNeels Hofmeyr1-3/+5
MSCR and CBQ3 are Release 1999 additions to the Control Channel Description IE of SI3. Assuming that no-one is using the spare bits, this will not cause any code conflicts. In the R99 struct, spare1 and spare2 are in different places, so rather rename them to spare_1 and spare_2 to make sure we get a compiler barf *if* anyone tries to use them with the wrong structure. Adjust the spec reference to TS 44.018; TS 04.08 Figure 10.5.33 is replaced by TS 44.018 Figure 10.5.2.11.1 which is right there in the named Section 10.5.2.11, so drop the explicit reference. Motivation: the R99 Control Channel Description defines MSCR to indicate whether the MSC is R99+ or not. To use UMTS AKA on GSM networks, we want to indicate that our libmsc is capable of R99, like OsmoSGSN already does. CBQ3 is merely added for completeness, no particular use case in mind.

2016-12-02Revert "gsm0408: add chreq_type for CHREQ_T_PDCH_ONE_PHASE and ↵Neels Hofmeyr1-2/+0
CHREQ_T_PDCH_TWO_PHASE" This reverts commit c3c28528de78fd5d50c3a141c2176c0da5dd7075. The reason is that this breaks a static assert in openbsc. See https://lists.osmocom.org/pipermail/openbsc/2016-December/009906.html Enlarging the ctype_by_chreq struct and breaks the static assert for gsm_network->ctype_by_chreq's size: ../../../src/libbsc/gsm_04_08_utils.c:138:1: error: size of array ‘dummyassert_size’ is negative osmo_static_assert(sizeof(ctype_by_chreq) == ^ What this patch lacks is, in openbsc.git: * adjustment of ctype_by_chreq[] according to the new additions in libbsc/gsm_04_08_utils.c * same for reason_by_chreq[], also in libbsc/gsm_04_08_utils.c * enlarge ctype_by_chreq[] in gsm_network to 18, in openbsc/gsm_data.h. Leaving it up to the original authors to follow up and commit a complete patch series in one go.

These inline functions relieve callers of the decision on masking bits of the protocol discriminator and message type octets. Also add a define for the protocol discriminator extension to one octet length (GSM48_PDISC_EXTEND). Apply new pdisc function in gsm0480.c. [hfreyther: Make the hdr param const]
