2018-06-29remove "channel" layerHarald Welte1-54/+0
The "channel" layer on top of IPA client + server was introduced in 2011 but never used in any osmocom program/project so far. Contrary to the several other IPA multiplex related implementations in libosmo*, it did not deal properly with segmented IPA messages, i.e. where a single TCP segment (and hence recv/read call) does not contain a full IPA message. So rather than fixing it up and having yet another IPA related API in our libraries, let's remove it. Change-Id: I97c378750acb1637ee032fa88a968edf68d8979f
2012-08-19channel: add subtype ID to osmo_chan_createPablo Neira Ayuso1-1/+8
This adds the possibility to specify the variant of the channel. This was discussed during the osmocom workshop. Harald wanted a way to say if the channel is using TCP, UDP, DADHDI and so on.
2012-08-19channel: osmo_chan_init takes one pointer to set the talloc contextPablo Neira Ayuso1-2/+2
Also remove this parameter from osmo_chan_create
2012-08-19channel: rename CHAN_* to OSMO_CHAN_* for correct namespace policyPablo Neira Ayuso1-4/+5
Just to avoid unlikely possible problems while using this library with any other that decided to define the CHAN_* constants.
2012-08-19channel: use linked list instead of array of existing channelsPablo Neira Ayuso1-0/+4
This also adds osmo_chan_init() that needs to initialize the channel infrastructure.
2012-08-19channel: define CHAN_SIGN_OML and CHAN_SIGN_RSL internallyPablo Neira Ayuso1-3/+0
These definitionsare not relevant for external client applications using the library.
2012-08-19channel: remove leftover unused definitions in headerPablo Neira Ayuso1-6/+0
They are not used anywhere in the code.
2012-08-18channel: add name fieldPablo Neira Ayuso1-0/+1
This will be useful to display some human-readable type in logs and the VTY.

2011-11-08src: add generic channel infrastructure and A-bis IPA server supportPablo Neira Ayuso1-0/+49
This patch adds the generic channel infrastructure that allows to create channel of different types. Each channel has their own configuration functions. struct osmo_chan *chan; chan = osmo_chan_create(tall_example, CHAN_ABIS_IPA_SERVER); ... /* specific configuration functions per supported channel. */ osmo_chan_abis_ipa_server_set_cb_signalmsg(chan, signal_msg_cb); osmo_chan_abis_ipa_unit_add(chan, 1801, 0); /* open channel. */ osmo_chan_open(chan); The input path requires a callback to be registered. The output path is handled through: int osmo_chan_enqueue(struct osmo_chan *c, struct msgb *msg); The msg->dst must be set (it can be taken from the original message to route one reply). This patch also adds A-bis IPA server support. It has been tested with e1inp_ipa_bsc_test available in libosmo-abis.
