* RSL: Add support for RSL_CHAN_OSMO_PDCH to rsl_dec_chan_nr()Harald Welte2017-07-301-0/+3

* osmo_sock_init2(): Fix creation of non-bound socketsHarald Welte2017-07-211-1/+1
| | | | | | | | | If osmo_sock_init2() was used with CONNECT flag but without BIND flag, an invalid check for "did we create a socket yet" caused the socket to never be created, and subsequently the entire function to return an error. Change-Id: I0206dbb9c5b8f74d7fb088576941b092acd2ca22
* add DLMGCP logging category for libosmo-mgcpNeels Hofmeyr2017-07-181-0/+5
| | | | | | | In the course of splitting up the openbsc.git repository, we will create libosmo-mgcp and need a library logging category for that purpose. Change-Id: I09c587e2d59472cbde852d467d457254746d9e67

* socket: Add new OSMO_SOCK_F_NO_MCAST_ALL optionHarald Welte2017-07-131-0/+10
| | | | | | | Using this option at socket creation, the caller can request disabling the IP_MULTICAST_ALL socket option. Change-Id: I5ab5de45c0b64ceb3636ea98245a23defa24ffd4
* socket: Allow disabling multicast loop on socket creationHarald Welte2017-07-131-4/+16
| | | | | | | | | | | This introduces a new flag OSMO_SOCK_F_NO_MCAST_LOOP, which can be used to disable the looping back of multicast packets transmitted throug this socket to other local sockets on the machine. As this looping-back is active by default, a single option to deviate from the default is deemed sufficient. Change-Id: I24a5b1ebc3f84d2d5d4734e54df50efaea26490b
* socket: Unify listen() calls and check for erroneous returnsHarald Welte2017-07-131-20/+33
| | | | | | | | | We had three places at the end of socket initialization functions calling listen(). Let's unify that and fix some bugs: * close + return error in case of bad listen() result * don't call listen() on AF_UNIX SOCK_DGRAM sockets Change-Id: I7e8dbe3c0486bb3b9810b0add1331e93fc106d82

* select: Add new osmo_fd_close() functionHarald Welte2017-07-131-0/+17
| | | | | | | | | This is a convenience helper that will both close a fd, mark it as closed and unregister it from the event loop abstraction. In most cases, you probably actually want to use it instead of manually closing and calling osmo_fd_unregister(). Change-Id: Icd0933eed6a24edde7cdcb378e138897ecc5332c

* Add pseudo-random bit sequence generator to libosmcooreHarald Welte2017-07-102-1/+75
| | | | | | | These PRBS sequences are specified in ITU-T O.150. They are typically used as test data to be transmitted for BER (bit error rate) testing. Change-Id: I227b6a6e86a251460ecb816afa9a7439d5fb94d1
* Ignore broken everything log levelMax2017-07-101-2/+9
| | | | | | | | | | | | | | | | * when reading config file (or vty command) ignore "logging level .. everything" level * when writing config file, skip "logging level .. everything" level In both cases print corresponding deprecation warning. The "everything" level is not working as advertised for quite some time anyway. This will allow us to gradually deprecate broken "everything" parameter giving users enough time to update their config files before removing it entirely.

* osmo_sock_get_name(): clearly indicate local and remoteNeels Hofmeyr2017-07-031-2/+2
| | | | | | | | | | | | | | | | In a string like 127.0.0.1:2905<->127.0.0.1:60661 it is hard to tell which is the local part. I'd have expected it on the left, but it is actually on the right. To avoid doubt and bypass bikesheds on which side should be what, clearly mark the two sides as remote and local. (r=127.0.0.1:2905<->l=127.0.0.1:60661) Change-Id: I43dcc6a1906429bd0955fd7fe2eb5b8495b592d8

* BSSGP: handle BVC-RESET-ACKMax2017-06-281-0/+3
| | | | | | | | | | | | | That's necessary for SGSN to properly handle BSS response to reset procedure initiated by SGSN (foe example via 'bssgp bvc nsei 101 bvci 0 reset' command). According to 3GPP TS 48.018 §8.4 "after performing the BVC Reset procedure all affected BVCs are assumed to be unblocked at the SGSN" so there's no need in any special handling.

* fix map entry for gsm0808_speech_codec_from_chan_typeNeels Hofmeyr2017-06-231-1/+1
| | | | | | | | | | | Recent commit 884ba0f2bcaf385cabee0b4228a2598d61fa406b adds function gsm0808_chan_type_to_speech_codec() but adds a mismatching name in libosmogsm.map. openbsc.git's aoip branch can't build with this. This must have been an on-the-fly rename that wasn't properly tested. Always test your patches! Change-Id: I68feb14f7bcb2f62b89f9b2d8c085d6824b493bc

* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-23130-553/+532
| | | | | | | | | | | | | | | | | 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).

* gsm0808: fix length check of the element decoder functionsPhilipp Maier2017-06-231-6/+6
| | | | | | | | | | | | | | | The length check of the decoder functions is not entirely correct. The check also checks for values below zero, which does not make sense, since the length is encoded as uint8_t. For some elements a minimum length is known (in most cases this is 1), so checking for zero is sufficient but in some cases (e.g. channel type) the spec mentions a minimum and maximum length. This is now also reflected in the code. Tweaked-by: nhofmeyr Change-Id: I78bc887f68d1963d28c6fcd631ac20ccd893d6d6

* gsm0808: add function gsm0808_speech_codec_from_chan_type()Philipp Maier2017-06-222-0/+55
| | | | | | | | | | | | | | | | 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

* core/conv/conv_acc.c: use static allocation for trellisVadim Yanitskiy2017-06-191-27/+23
| | | | | | | | | | | Allocation of a new memory is an expensive operation, which takes place when it's initially unknown, how much memory will we need, or in order to decrease total memory usage. The trellis struct wasn't require dynamic allocation itself, so let's allocate one statically inside the vdecoder structure. Change-Id: Ib8e448823ca5548a05a45824b0b1c06743dfe5a4

| | | | | | | | | | | | | | | Currently this implementation exposes nothing than osmo_conv_decode_acc(), so it wasn't possible to call reset_decoder() from outside. The method itself was used to initialize accumulated path metrics and the starting state of encoder. Now this code is moved to generate_trellis().
