* gsm0808: add default speech codec configurationPhilipp Maier2017-06-221-0/+21
| | | | | | | | | In an AoIP scenario, the speech codec list field specifies the codecs used in the RTP interface. This patch adds a table with default codec configurations that match the codec configurations that are also used on the air interface. Change-Id: I9dc0165d76a022b2c1b7418bc3133407e61b7261
* gsm0808: fix AoIP speech codec element parser/generatorPhilipp Maier2017-06-221-2/+0
| | | | | | | | | | The implementation of the parser/generator for the speech codec information element slightly wrong, making it impossible to use it properly. (See also: 3GPP TS 48.008, 3.2.2.103) Change-Id: Idabb0f9620659557672e1c6b90c75481192e5c89
* gsm0808: add speech codec type constantsPhilipp Maier2017-06-211-0/+18
| | | | | | | | The codec type to be set in member type in struct gsm0808_speech_codec has its own coding scheme to reference the used codec types. This patch declares an enum with valid speech codec types. Change-Id: Icaa768071d4364e671bc7e6d48b82d1f07f93f93

* gsm_04_08: Add missing GSM cause valueDaniel Willmann2017-05-121-0/+3
| | | | | | | | | | | | Table 10.5.157 in 10.5.6.6 of 3GPP TS 04.08 is badly formatted. The first value 0x19 "LLC or SNDCP failure" is in the same line as the heading and has not been included in the struct_value so far. Table 10.5.157 in 10.5.6.6 of 3GPP TS 24.008 fixes this formatting issue and also defines two more values 0x08 and 0x18 which are now added to the struct value_string.

* ipa: Introduce helpers to encode IPA CCM ID RESPONSEHarald Welte2017-04-151-0/+7

Let's change that with ipa_ccm_make_id_resp() and a helper wrapper ipa_ccm_make_id_resp_from_req(). Change-Id: Icbcd8827a75fd5f3393351c1ca372de85275ad35

* add gsm48_pdisc_msgtype_name()Neels Hofmeyr2017-03-161-0/+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.

| | | | | | | | | | 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.

* gsm_04_08.h: add R99 MSCR and CBQ3 to SI3 Ctrl Chan DescrNeels Hofmeyr2017-02-231-3/+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.

* GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr2017-02-021-1/+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
