2019-03-07AMR: add functions to convert between bw-efficient and octet-alignedpmaier/amrmanglePhilipp Maier6-2/+612
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.

2019-03-01AMR: add define constants for AMR payload lengthPhilipp Maier2-9/+21
AMR uses different payload sizes, those sizes are well defined in RFC 3267. Lets add define constants and replace the magic values with the define constants. Also correct the value for AMR_FT_SID in amr_ft_to_bytes from 6 to 5 (39bits / 8 = 4.875 bytes ==> 5 byte, see also RFC 3267, chapter 3.6) Change-Id: I65b5da920d58015b875d6dcf17aacdc04b58955e
2019-02-28debian: Add BuildDepends on libpcap0.8-devHarald Welte1-0/+1
The debian packaging wants to execute "make check" which in turn wants to build the jitterbuffer tests, which in turn require pcap.h to be present, which is provided by libpcap0.8-dev. Closes: OS#3818 Change-Id: Iab471de9fb276a436332241337539eab544f965a

It's similar to connect_cb() but called once client has been disconnected. Change-Id: I905adb2d6191216551a3bcdcd1aec1f96f01612a
2019-02-07Add stream client/server testMax6-1/+418
Previously stream client and server code were only used in examples which means regressions could be easily introduced unnoticed until they trigger bugs in external code which relies on osmo_stream_*() Fix this by adding basic client-server interaction tests with and without reconnection. Change-Id: I336f79970982ed8e1d73b73d54fa4c27ba8bce8e

Likely a copy-paste error from corresponding client example code. Change-Id: I47cc8c7340eb188d85a49d4f41c295bed0e1bee4
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.

2019-02-05Add socket name functions to stream client/serverMax4-2/+35
Add functions to get the description of a server link or client connection which examine data on corresponding socket. Those functions use static buffers and intended for single use in log/printf statements as illustarted by corresponding example changes. Change-Id: If9a8e211da85956781479862a63c4fc6e53ed6be

Stream server example had an error which resulted in infinite loop on client disconnect. Fix this by properly handling client closing connection to allow it to reconnect multiple times. Change-Id: Icfc2cf7f971b9e3a4abc34cc18d8a44c811c5617

While we are processing a read event, the connection's callback might free the connection. Check for this and don't attempt to process further events on an already freed connection. Change-Id: I0a9c7d8e3263c73440f7084dbb1792a4ca5038f0 Related: OS#3685 Depends: g#11704 (for libosmo-sccp)

2018-08-06debian/rules: Don't overwrite .tarball-versionHarald Welte1-5/+1
The .tarball-version file should contain the *source version* uniquely identifying the git commit, and not the Debian package name. With https://gerrit.osmocom.org/#/c/osmo-ci/+/10343/ there is a correct .tarball-version file in the .tar.xz of the nightly source packages.

2018-08-01link libosmo-netif against libosmogsmHarald Welte1-2/+2
The recently-introduced dependency to libosmogsm symbols needed some explicit addition of linker flags to avoid user applications to fail linking with /usr/bin/ld: /usr/local/lib/libosmonetif.so: undefined reference to `ipa_ccm_id_resp_parse' Change-Id: I07a28f8970b90f82736e2de783bafc9d2c5ea0e5
2018-08-01Migrate from osmo_ipa_idtag_parse() to ipa_ccm_id_resp_parse()Harald Welte4-37/+7
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. Let's use this opportunity to remove the copy+pasted osmo_ipa_idtag_parse() function from the libosmo-netif codebase. Change-Id: I4626d247626543e032593bf226b6c233f6678562

2018-07-05stream.c: Use non-blocking connect in osmo_stream_cliHarald Welte1-1/+1
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. The libosmocore socket API provides the OSMO_SOCK_F_NONBLOCK flag for this. Make use of it! Change-Id: I9bfcb39b5801a36ef32ca0d1f3eb8236687d7ed6 Related: OS#3383
2018-06-29remove "channel" layerHarald Welte18-1141/+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

In Change-Id: I2efed6d726a1b8e77e686c7a5fe1940d3f4901a7 we're adding a new member to 'struct osmux_out_handle' which is not initialized.

2018-04-19osmux: Set Marker bit on osmux frame loss detectedPau Espin Pedrol4-12/+34
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 Pedrol2-3/+141
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
