2019-09-04stream: Fix scheduling of queued messages during connecting statePau Espin Pedrol1-1/+6
If messages are sent using osmo_stream_cli_send() while the stream is still (re)connecting, they won't have a chance to be sent until the stream is connected, and hence they are queued until CONNECTING->CONNECTED is done. However, at that time (osmo_stream_cli_fd_cb), the WRITE flag was dropped unconditionally, which meant already queued packets didn't have the opportunity to be sent by the same callback until first message is enqueued and WRITE flag is set (again by osmo_stream_cli_send()). Let's make them be sent as soon as possible once the connection is available. Related: OS#4188 Change-Id: I289495f9aad6389c5f2623fb072d676235b7d24c

2019-03-20amr: use sizeof(struct amr_hdr) when working with amr header lengthPhilipp Maier1-3/+3
The header of an AMR header payload is 2 bytes long. At the moment we use just a constant of 2 when we refer to the header length, but we have a struct amr_hdr defined. Lets use sizeof(struct amr_hdr) to make it more clear that we are refering to the header length. Change-Id: Ic7ca04b99a97d7d3b91717b0c3e6c55ef3001a3e
2019-03-19Deprecate osmo_stream_cli_open2()Max1-6/+42
This supposed to be variant of osmo_stream_cli_open() with explicit control over reconnection logic but it's plain broken: doxygen docs contradict the code, actual reconnection logic is affected by timeout parameter directly which is set in different function. It seems like we haven't been affected by this so far because we always use it in auto-reconnection mode which is triggered by default due to positive reconnection timeout value (5 sec) automatically used in the absense of explicitly set timeout. Looking at commit history, this function already been source of confusion in the past. Instead of trying to fix this mess, let's just deprecate it entirely and properly document use of osmo_stream_cli_set_reconnect_timeout() to control reconnection logic. The only known user is libosmo-sccp which won't use it as of 0a93a683f3cb8e5977eb4a666ab207db6e7d7af9 commit. Change-Id: Id988ed0274b363db049f59cbf6a193727c8c3c8a
2019-03-12amr: be sure result of osmo_amr_bwe_to_oa() fits into int bufPhilipp Maier1-1/+1
osmo_amr_bwe_to_oa() uses an internal buffer with static size to store intermediate results. The buffer is large enough for any real world situation, but the check that tests if the result would fit into the internal buffer is incorrect. It checks if there is enough room for the existing payload, but does not include the expected growth of the payload. Eventually the buffer could be overrun by one byte if one would put a 256 byte long AMR payload. Fixes: CID#195926 Change-Id: I4d7ac570a0b48368a82183673c46bca5f235f228

2019-03-07AMR: add functions to convert between bw-efficient and octet-alignedpmaier/amrmanglePhilipp Maier1-0/+112
RFC 3267 describes two different AMR frame formats. Octet Aligned and Bandwidth efficient mode. In Bandwith efficient mode the padding bits, which are used to align CMR, TOC and payload on octet boundaries are saved and the fielda are packed directly one after another. - Add functions to convert from one mode to the other and vice versa. - Add function to detect in which mode an AMR frame is encoded.

2019-02-05Stream client: fix disconnection logicMax1-2/+8
Previously closing the client did not alter its state, so we might end-up with a client without any file descriptors, but being in state STREAM_CLI_STATE_CONNECTED. Fix this inconsistency by setting appropriate state. Related issue is that reconnect function, which is always (at least in the library and examples) called when some problem with the connection is detected, closed the connection only after checking whether reconnection is enabled. This might result in another inconsistency fixed in this patch by moving the check below connection cleanup. While at it, also move connection close logging to appropriate place: it's confusing to see logs about connection being closed while in reality it wasn't even established.

In libosmocore Change-ID I1834d90fbcdbfcb05f5b8cfe39bfe9543737ef8f we have introduced ipa_ccm_id_resp_parse() as a bugfixed replacement of ipa_ccm_idtag_parse(). The main difference is that the returned "value" parts now have a correct reported "length", whereas before this commit they all reported a one-byte too-long "length" for each IE.

When establishing a client-side stream connection via libosmo-netif, we must using non-blocking connect if we want to avoid blocking/stalling the entire process.

2018-06-29remove "channel" layerHarald Welte7-861/+1
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

2018-04-19osmux: Set Marker bit on osmux frame loss detectedPau Espin Pedrol1-2/+16
Until this patch, we didn't notify in any way to the RTP reader when an Osmux frame was lost. Instead, we updated the seq&timestamp as if there was no lost, and as a result the RTP reader would only see a steady increase of delay every time an osmux frame was lost. As the batch_factor for the lost packet is unknown, we cannot assume any number of amr payloads lost, and thus we cannot simply increment seq and timestamp for a specific amount. Instead, the only viable solution seems to set the M marker bit in the first rtp packet generated after a non-consecutive osmux frame is received. The implementation may act differently with the first generated RTP packet based on the first osmux seq number used for the stream. In case 0 it's used as first osmux seq number, M will be set depending on request from original RTP packet having the M bit set. If it's not 0, the first RTP packer will unconditionally have the M bit. That's not an issue because it's anyway expect for receiver to sync on the first packet.

2018-04-19osmux: Add new API osmux_xfrm_output_sched to fix rtp generation issuesPau Espin Pedrol1-1/+131
With old implementation, in conditions with jitter we could end up scheduling RTP generated packets from two consecutive osmux frames in an interleaved way (from seq field point of view). This new implementation should make it easier for any RTP reader/playback to have better results in those conditions. Old APIs osmux_xfm_output and osmux_tx_sched are marked as deprecated in favour of the new one, which has a better control of generated RTP packets. However, they are still usable despite the implementation changes done to support the new API. Related: OS#3180 Change-Id: I4e05ff141eb4041128ae77812bbcfe84ed4c02de
