2017-04-08gsm0808: Add create functions for BSS_MAP_MSG_ASSIGMENT_RQSTPhilipp Maier1-0/+5
gsm0808.h/c lacks functionality to generate BSS_MAP_MSG_ASSIGMENT_RQST messages. These messages are required if the code is used in an MSC implementation. This commit adds a gsm0808_create_assignment() function, that generates an A/AoiP BSS_MAP_MSG_PAGING message. Change-Id: I4d1d455a1e1cf95407e23ded7b7defbcf2dd6ff0

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
I often want to log the protocol discriminator in the openbsc debug log. It's more useful to get the name directly instead of looking it up every time. Change-Id: I0f053e2a4360b27ffccda7cf82469fb1b1cbb3ae

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.

2017-02-02GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr1-1/+1
GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS to our osmo_auth_gen_vec_auts() API. According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14 bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2 and AUTS being the V = 14. It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But writing 16 bytes to a GSUP struct is a potential problem when passing in a 14 byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer. The API implies the length, so far to be 16, so passing in a 14 byte buffer to GSUP would require copying to a larger buffer first. Fix this by using a length of 14 for AUTS everywhere instead. This constitues an ABI breakage, we may handle it as a "fix before an official release", otherwise we need a version bump. The OAP protocol document has also been updated, needs an update in the osmo-gsm-manuals as well. Change-Id: If25b173d9ec57ea4c504d860954912b7d82af455

2016-12-11import oap message parsing / encoding from openbsc.git; AGPL->GPLHarald Welte1-0/+72
In the process, also: * Change the license from AGPLv3 to GPLv2-or-later; * correct spelling of 'sysmocom' to lowercase; * add '2016' to the copyright; * rename to osmo_*; * add API docs; * add logging category DLOAP: define id and add to internal_cat; * redirect all oap.c logging to DLOAP. A unit test will follow in a subsequent patch, since it needs a minor tweak for decoding of boolean values. The related openbsc change-id is I2f06aaa6eb54eafa860cfed8e72e41d82ff1c4cf.

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.
2016-12-01gsm0480: add gsm0480_create_ussd_notify() and *_release_complete()Neels Hofmeyr1-0/+2
Add two functions to create USSD messages. Moves and generalizes code from openbsc. Pending: use the new functions in openbsc. It looks like _release_complete() should also set trans_id and direction flag; but since this is moving code from openbsc that is apparently working, just place a fixme comment and don't change the functionality.
