* tlv_put: guard against NULL val and 0 lenNeels Hofmeyr2017-11-201-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | For example encode_auth_info() from gsup.c calls msgb_tlv_put(msg, iei, 0, NULL) to put a tag and len with content data following later. However, this would cause a memcpy() from a NULL pointer, in tlv_put(). Allow passing NULL and len = 0 for cases like the above: If val is NULL, use memset(0) instead of memcpy(). If len is zero, do not copy nor memset anything. Hence make tlv_put() behave in a well-defined and valid way for any and all input args; no negative fallout is possible from this patch. Add proper API doc comment. Fixes a sanitizer build failure in gsup_test: ../../../../src/libosmocore/include/osmocom/gsm/tlv.h:99:2: runtime error: null pointer passed as argument 2, which is declared to never be null Helps fix sanitizer build on debian 9.

* Add function to generate random identifierMax2017-10-091-0/+5
| | | | | | | | | | | | | | | | | The function is a wrapper on top of getrandom() (if available via glibc) or corresponding syscall. If neither is available than failure is always returned. It's intended to generate small random data good enough for session identifiers and keys. To generate long-term cryptographic keys it's better to use special crypto libraries (like GnuTLS for example) instead. As an example it's used to replace old insecure random number generator in osmo-auc-gen utility. Change-Id: I0241b814ea4c4ce1458f7ad76e31d390383c2048 Related: OS#1694

* tlv: add [msgb_]t16lv_put() for 16bit tag + 8 bit len TLVsHarald Welte2017-08-091-1/+20
| | | | | | | | | | | In the Protocol Configuration Options IE (see 3GPP TS 24.008 10.5.6.3) there is yet another new TLV format (derived from PPP IPCP/LCP/...) which uses 16bit tag and 8bit length. Let's add functions so we can generate related TLVs. Parsing is unfortunately not possible in our existing structure as our tlv_parsed array only has 256 entries and thus cannot cope with 16bit tags.

* 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

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

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
