2019-04-25osmux: Cleanup of CID alloc pool APIsPau Espin Pedrol1-10/+19
* Cleanup naming to make it far more clear * Drop 2 variables holding CID values (allocated_cid, cid), in favour of 1 value holdinf the value and one bool stating whether the value is used. * Change conn_osmux_allocate_cid to allow allocating either next available CID or a specific one, in preparation for forthcoming patches. This commit can be merged straight away because anyway osmux cannot be enabled in current status (blocked by vty config) and (conn_)osmux_allocate_cid was/is not called anywhere. However, it helps improving code base for future re-introduction of Osmux as it is envisioned. Change-Id: I737a248ac6c74add8e917fe2e2f36779d0f1d685

2019-03-12AMR: Add function to convert between bw-effient and octet aligned modePhilipp Maier2-1/+54
RFC3267 specifies two framing modes for AMR packets. An octet aligned mode is specified where all fields of the AMR packets are aligned to octet boundaries. The second framing mode is the bandwith efficient mode where the fields are directly packed one after another. - add paring/generation functions for related SDP fmtp parameters - add conversion function to convert AMR payload Depends: libosmo-netif I5b5a0fa644d8dbb1f04f9d7e35312683c7b3d196 Change-Id: I622c01874b25f5049d4f59eb8157e0ea3cbe16ba Related: OS#3807
2019-02-06Inactive connection cleanup (disabled by default)Oliver Smith1-0/+4
Add a watchdog timer to connections, and close these connections when the watchdog timer expires. Kick the watchdog whenever RTP messages or the relevant MGCP messages arrive. Add the currently remaining timeout to "show mgcp stats" in the VTY. This feature is disabled by default, as it is incompatible with LCLS (connections in LCLS state appear to be inactive). Enable it with the new "conn-timeout" VTY setting. In general, this feature can be used to work around interoperability problems causing connections to stay open forever, and slowly exhausting all available ports. This happened for various reasons already. MDCX is the only relevant MGCP message: - CRCX creates the conn and timer - DLCX deletes the conn and timer - MDCX is the only remaining supported MGCP message that indicates a CI - Can't easily generically parse a CI for all MGCP messages, parsing is done in handle_modify_con().

2019-01-03mgcp_client: make domain part of endpoint configurableNeels Hofmeyr1-0/+2
So far, both osmo-msc and osmo-bsc always pass endpoint names of the form '...@mgw' to osmo-mgw. Allow configuring the 'mgw' part. Note that the actual way to pass a differing name is to pass a composed 'rtpbridge/*@foo' to mgcp_msg_gen() in the struct mgcp_msg. So this merely adds a common VTY config for the domain name part, changes to clients are necessary. - add mgcp_client_rtpbridge_wildcard() (useful for AoIP endpoints) - add mgcp_client_endpoint_domain() (useful for SCCPlite endpoints) - add mgcp client vty cfg 'mgw endpoint-domain NAME' Rationale: reading pcaps becomes so much easier when each of osmo-bsc and osmo-msc address their MGW with differing domain names. Otherwise, both will have a '0@mgw' endpoint and it gets really confusing. Also: our MGCP clients osmo-bsc and osmo-msc use code dup to compose the initial 'rtpbridge/*@mgw' rtpbridge wildcard. It should be defined by this API instead. This will be used by: * osmo-msc I87ac11847d1a6d165ee9a2b5d8a4978e7ac73433 * osmo-bsc I492023e9dca0233ec0a077032455d9f2e3880f78 After these, with according configuration, there can be a '0@bsc' and a '0@msc' endpoint on two separate osmo-mgw instances: osmo-mgw-for-bsc.cfg: mgcp domain bsc osmo-bsc.cfg: msc 0 mgw endpoint-domain bsc osmo-mgw-for-msc.cfg: mgcp domain msc osmo-msc.cfg: msc mgw endpoint-domain msc There can also be '0@bsc' and '1@msc' endpoints on one single osmo-mgw instance with: osmo-mgw.cfg: mgcp domain * and same osmo-{bsc,msc}.cfg as above. (By default, everything will still use '@mgw') Change-Id: Ia662016f29dd8727d9c4626d726729641e21e1f8
2018-12-19mgcp_client: drop a bunch of dead codeNeels Hofmeyr3-196/+0
Remove public API that makes no sense anymore and is dead code. I see the dropped API as a dead-end initial misconception of the early mgcp client, and it doesn't really make sense to drag this stuff along. It has not been used by osmo-msc,-bsc for a long time now, and just confuses the reader. It is public API, yes, and older versions of osmo-msc / osmo-bsc will not be able to compile against this, but even if it did, the resulting MGCP client would not work with the current osmo-mgw: this API is still based on the premise that the MGCP client dictates the MGW endpoint numbers, a concept that cannot be used with the current osmo-mgw. Instead, osmo-mgw expects a wildcarded endpoint upon CRCX and assigns its own endpoint names. Also, the bts-base configuration is unused and a legacy of when osmo-bsc_mgcp had explicit BTS and CN sides. Change-Id: I98a9f1f17a1c4ab20cea3b08c7d21663592134d6

2018-09-07mgcp_conn_get(): match conn Id ('I:') despite leading zerosNeels Hofmeyr2-0/+12
The Connection Identifier is defined as a hex string, so clients may send the ID back with or without leading zeros. Ignore all leading zeros when comparing. A specific SCCPlite MSC is observed to DLCX with Connection Identifier with leading zeros removed, which would mismatch pefore this patch. Extend test_conn_id_matching() in mgcp_test.c to include leading zero tests. Now, mgcp_conn_get() would match a valid id with *any* amount of leading zeros, even if that far surpasses the permitted conn id length. Valid lengths of incoming conn ids should be and is checked elsewhere. Related: OS#3509 Change-Id: If55a64a2da47b6eff035711c08e4114d70dbec91
2018-09-07mgcp_conn_get(): compare conn Id ('I:') case insensitivelyNeels Hofmeyr2-0/+39
The Connection Identifier is defined as a hex string, so clients may send the ID back in lower case. Convert to upper case before comparing. A specific SCCPlite MSC is observed to DLCX with Connection Identifier in lower case, which would mismatch pefore this patch. Add test_conn_id_matching() in mgcp_test.c to verify case insensitivity. Cosmetic: use strcmp(), not strncmp(). In the presence of a terminating nul as we can assume here, this makes no functional difference, but it clarifies the code.

2018-09-03fix mgcp_verify_ci(): off-by-one in max len checkNeels Hofmeyr2-0/+20
MGCP_CONN_ID_MAXLEN actually includes a terminating nul, so we need to compare strlen() against MGCP_CONN_ID_MAXLEN-1. Log the length if it is too long. Add MDCX_TOO_LONG_CI test to mgcp_test.c, testing a conn id of 33 characters. Before this patch, the test returns error code 515 meaning "not found", while now it returns 510 meaning "invalid", showing the off-by-one. Same is illustrated by the error log ("not found" before, "too long" now), but the error log is not verified by mgcp_test.c. Change-Id: I8d6cc96be252bb486e94f343a8c7cae641ff9429

2018-08-28X-Osmo-IGN: rather parse items by token, not charNeels Hofmeyr2-2/+2
Adjust the X-Osmo-IGN parsing to use string tokens instead of parsing single characters. Reconsidering the first implementation as a poor choice, rather specify the format of X-Osmo-IGN as any-length string tokens separated by spaces, which is more flexible and more future proof. See also osmo-gsm-manuals If15a88c3b5b40fd1d24ad0f94f3231f678669ab1 which defines the X-Osmo-IGN format as string tokens, matching this patch. In mgcp_test, add an unknown X-Osmo-IGN item. Though the output is not checked by the testsuite.at, running manually shows the error log about the unkown X-Osmo-IGN item. Change-Id: Ia6fe5ead4b601931c1bf41b29fc1b237aac37d2c
2018-08-25add X-Osmo-IGN MGCP header to ignore CallIDNeels Hofmeyr4-1/+70
The format is CRCX ... C: ... M: ... X-Osmo-IGN: C So far the only ignorable element is C, i.e. the CallID. Any other items may be added in the future. (I initially intended to also add '@' to ignore the endpoint name's domain part, but in the osmo-mgw code base the domain part is verified long before any additional headers are even parsed, so sparing that refactoring for now.) The intention is that osmo-bsc will issue "X-Osmo-IGN: C" for all SCCPlite calls, because we are unable to retrieve the CallID that the MSC sends to osmo-mgw for the network side of the endpoint. Testing with a specific SCCPlite MSC, I actually observe that all CallIDs are 1, even for concurrent calls. So, an alternative hacky solution would have been to always pass CallID == 1 for SCCPlite connections from osmo-bsc.

2018-08-02mgcp_test: release endpoints after usePhilipp Maier1-0/+4
The test function test_multilple_codec() in mgcp_test.c creates a lot of connections, but it never releases them. Just freeing the cfg object is not enough since the UDP ports stay open and this may interfere with other tests that also create connections (port numbers). - Make sure all endpoints are released when test_multilple_codec() is done.

2018-07-31mgcp_network: translate payload type numbers in RTP packetsPhilipp Maier1-0/+95
Since no transcoding is in place osmo-mgw forwards the incoming rtp packets as they are (there may be minor modifications of the header) from an ingress connection to an egress connection. This works without problems as long as both connections use the same payload type. For IANA defined fixed payload type numbers this is usually the case, but for dynemic payload type numbers both ends may set up the same codecs but with different payload type numbers. When different payload type numbers are set up, and the packet is passed through without modification, it will have the wrong payload type when it is sent. The receiving end may then toss the packet since it expects packets with the payload type it has configured. The machanism, which is introduced with this patch looks up actual codec inside the struct data of the ingress connection and then looks for the matching codec in the struct data of the egress connection. When it finds the codec there it looks up the payload type of this codec. The header of the RTP packet is then patched with the correct payoad type. - Add function mgcp_codec_pt_translate() to look up the payload type - Add unit-test for function mgcp_codec_pt_translate() - Add payload type translation to mgcp_network.c Change-Id: I3a874e59fa07bcc2a67c376cafa197360036f539 Related: OS#2728 Related: OS#3384

2018-06-23mgw: clean up codec negotiation (sdp)Philipp Maier2-20/+61
The codec negotiation via SDP is currently in a neglected state. Also osmo-mgw does some kind of codec decision wile the SDP is parsed, the result is information for one codec, even when there are multiple codecs negotiated. This is problematic because we loose all information about alternate codecs while we parse. This should be untangled and the information should be presevered. Also we are not really capable picking a default. Wehen we do not supply any codec information (not even LCO), then we should pick a sane default codec. - separate the codec decision from the sdp parser and concentrate codec related code in a separate c file - add support for multiple codecs in one SDP negotiation - do not initalize "magic" codec defaults during conn allocation - do not allow invalid payload types, especially not 255. When someone tries to select an invalid payload type, do not fail hard, just pick a sane default. - handle the codec decision in protocol.c, pick a sane default codec when no (valid) codec has been negotiated (no LCO, no SDP) Change-Id: If730d022ba6bdb217ad4e20b3fbbd1114dbb4b8f Closes: OS#2658 Related: OS#3114 Related: OS#2728

Previously we * did not distinguish between the cause of errors in mgcp_header_parse * common errors were not handled in mgcp_handle_message() but in individual per-verb functions Let's centralize the handling of generating error responses and remove that burden from the individual per-verb handler functions.

2017-12-04mgcp_test: add returncode checkPhilipp Maier2-3/+33
The returncode of get_conn_id_from_response() is unchecked, which is intentional since some of the test messages will intentionally cause this function to fail (the response does not inclde a connection identifier). This means it makes no sense to assert this function to a fixed value. In order to spot regressions better print a log message depending on the return code.
