| | | | | | | | | The PDP charging characteristics will be returned from the PDP selection code and be used in the SGSN. It is following the same approach as the QoS and PDP addr. It is a bit of a pity that we have to define this in a different project. Change-Id: I7815c5dfd7b7fb0ea78d816ebfb3abfbf0090afe

* fix map entry and .h declaration for gsm0808_chan_type_to_speech_codec()Neels Hofmeyr2017-06-231-1/+1
| | | | | | | | | | | | Recent commit 3149b0d076477303a38df735fe579b1b06ee17b2 adds function gsm0808_chan_type_to_speech_codec() but adds a completely mismatching name in libosmogsm.map, as well as a definition with a typo in the name. Fix the entry in libosmogsm.map. Add the missing 'c' in gsm0808_utils.h Change-Id: I5a621fa5ef6b632eabbe224f3dd383eacaffb695
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-2349-74/+121
| | | | | | | | | | | | | | | | | 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).

* doxygen: enable AUTOBRIEF, drop \briefNeels Hofmeyr2017-06-2314-321/+321
| | | | | | | | | | Especially for short descriptions, it is annoying to have to type \brief for every single API doc. Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes the first sentence of an API doc as the brief description. Change-Id: I11a8a821b065a128108641a2a63fb5a2b1916e87
* cosmetic: remove API documentation strings in header filePhilipp Maier2017-06-221-24/+0
| | | | | | | | | | | | Typically we don't place comments with the function declarations in .h files. Not sure why this file has comments for each. The API doc belongs in the .c file as proper doxygen comments, and shouldn't be duplicated in the .h file. In this particular case, doxygen comments are added in the corresponding c file recently.

* gsm0808: add function gsm0808_speech_codec_from_chan_type()Philipp Maier2017-06-221-0/+2
| | | | | | | | | | | | | | | | The contents of the speech codec element (struct gsm0808_speech_codec), that is also used in the speech codec list element (struct gsm0808_speech_codec_list) can be generated directly from the permitted speech parameter in the channel type field (struct gsm0808_channel_type) when full AoIP with compressed speech via RTP/UDP/IP is assumed and when the codec configuration on the air interface exactly matches the codec configuration on the IP backhaul. This patch adds a function that can be used as a helper to fill out spech codec fields by only giving a permitted speech parameter as input. Change-Id: I257c972e9fdf0dfe940a8d483447085bd62e50a2
* gsm0808: add function gsm0808_chan_type_to_speech_code()Philipp Maier2017-06-221-0/+2
| | | | | | | | | | | | The permitted speech field used in channel type element (struct gsm0808_channel_type) uses a different representation as the type field in the speech codec element (struct gsm0808_speech_codec) This patch adds a function to convert from permitted speech to speech codec type.

* 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

* 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.

* 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
