2014-05-26rsl: Check if the channel is active and then start the channel releasehfreyther/fixes/channel-release-handlingHolger Hans Peter Freyther1-16/+12
In case we receive ERROR INDICATION and CONNECTION FAILURE we only want to RF Channel Release the lchan once. This code is more simple and should work as reliable as the previous commit.
2014-05-26rsl: Avoid double channel release procedure in error conditionsHolger Hans Peter Freyther1-5/+20
When we receive an ERROR INDICATION and CONNECTION FAILURE we might call rsl_rf_chan_release multiple times. The channel release handling is still a bit messy and there too many paths that lead to the call. 1.) In case we receive an ERROR INDICATION for SAPI=3. A RLL error signal will be emitted that leads to the release of the channel through the SMS code in case of the NITB. The call to rsl_rf_chan_release might be a double release. 2.) In case a CONNECTION FAILURE is received when the release process has already been started we would unconditionally call rsl_rf_chan_release as well. Because the lchan state is changed by the callers of the rsl_rf_chan_release we can not move the state checking into this code but need to do it in the caller. The issue was seen in a trace from Rhizomatica and I created the DoubleRelease.st to re-produce the issue and verified that we have no duplicate RF Channel Releses. The other option would be to introduce a new state to track the release process and see if we have already released SAPIs deactivated the SACCH or such. We can not simply look at these as for a channel that fails to activate they will be null already.
2014-05-26lchan: Speculative "fix" for error and late replyHolger Hans Peter Freyther1-8/+9
Looking at the code it seemed possible that a channel would transition from BROKEN to NONE. Or worse from NONE to BROKEN. Start the timer _after_ the channel has been released.
2014-05-26mgcp: Use #pragma once instead of a possible clashing #ifdefHolger Hans Peter Freyther1-3/+1
The filename is mgcp_internal.h but the define refers to MGCP_DATA. Avoid having a potential clash by using the #pragma once option.
2014-05-26rsl: Remove obsolete FIXME comment.Holger Hans Peter Freyther1-1/+0
The lchan state is set to none either on RF Channel Release ACK or in case of an error after the error timer has expired.
2014-05-22osmux: Fix potential memory leak in the msgb handlingHolger Hans Peter Freyther1-0/+2
2014-05-22mgcp: Add proper length checking for line handlingHolger Hans Peter Freyther2-0/+23
In ae1997248ccb4fba1394267d3051082dfd85448a the handwritten tokenizer was replaced with strtok_r. As part of this change the structural checking of MGCP parameters was stopped. This means that a code like "line + 3" might access beyond the first NUL and be possibly behind the msgb. Manually add size checking again. Manually jumping to the error label is not possible anymore as it has been removed. The result is that invalid lines will be skipped. This is matching the general approach by the IETF RFCs to be permissive in data being received.
2014-05-22mgcp: Remove excessive logging for each frameHolger Hans Peter Freyther1-12/+0
2014-05-22mgcp: add voice muxer supportPablo Neira Ayuso18-48/+629
This patch adds the voice muxer. You can use this to batch RTP traffic to reduce bandwidth comsuption. Basically, osmux transforms RTP flows to a compact batch format, that is later on decompacted to its original form. Port UDP/1984 is used for the muxer traffic between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This feature depends on libosmo-netif, which contains the osmux core support. Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using the vendor-specific extension X-Osmux: on) coming from the BSC-NAT, so you can selectively enable osmux per BSC from one the bsc-nat.cfg file, so we have a centralized point to enable/disable osmux. First thing you need to do is to accept requests to use Osmux, this can be done from VTY interface of osmo-bsc_nat and osmo-bsc_mgcp by adding the following line: mgcp ... osmux on osmux batch-factor 4 This just initializes the osmux engine. You still have to specify what BSC uses osmux from osmo-bsc_nat configuration file: ... bsc 1 osmux on bsc 2 ... bsc 3 osmux on In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does not have osmux enabled. Thus, you can selectively enable osmux depending on the BSC, and we have a centralized point for configuration from the bsc-nat to enable osmux on demand, as suggested by Holger. At this moment, this patch contains heavy debug logging for each RTP packet that can be removed later to save cycles. The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that is received to configure an endpoint.

2014-05-22rtp_proxy: Prevent out-of-bounds read in rtcp_sdes_cname_mangleDaniel Willmann1-1/+1
In rtcp_sdes_cname_mangle when skipping over additional zeroes at the end of a chunk we should not read past the actual message (rtcp_end). Fixes CID #1206579
2014-05-19chan_alloc: Fall-back to TCH/H, if we cannot find a TCH/FHarald Welte1-0/+5
I'm not entirely sure if this is the best approach. However, there are phones that send a RACH request for TCH/F on MO calls, even though they actually do support TCH/H channels.
2014-05-18rtp_proxy.c: Correctly set msg_type to GSM_TCH_FRAME_AMR on AMRHarald Welte1-0/+1
When forwarding AMR from RTP towards the MNCC interface, we need to set the apropriate msg_type. Before this patch it was unitialized, resulting in improper/unknown msg_types of messages on the MNCC interface.
2014-05-18rtp_proxy: Simplify AMR handlingHarald Welte1-30/+26
AMR frames on the MNCC interface are slightly different as they include a single-byte payload_length indicator prior to the actual payload. Commit 3f201ac89952b68d05c0bb6cb41932b9cd898b19 introduced more special-case handling than required, so I'm trying to simplify things again. We now also use msgb_put() more consistently, i.e. always put before actually using the data, and use the return value of msgb_put() rather than first making assumptions about the pointer, writing to it and then calling msgb_put().
2014-05-18Add support for AMR frames to MNCC/RTP interfaceAndreas Eversberg2-6/+48
AMR rate is currently fixed to 5.9k.
2014-05-18bsc_api/NITB: If TCH/H channel is used, indicate it to bsc_apiAndreas Eversberg1-1/+2
If we don't do this, OsmoNITB will send an assignment command from a TCH/H to another TCH/H without any need.

2014-05-15ctrl: Use CTRL_CMD_DEFINE_STRUCT in CTRL_CMD_DEFINE_RANGEHolger Hans Peter Freyther1-6/+1
Jacob pointed out that I didn't convert CTRL_CMD_DEFINE_RANGE. This patch is doing it now.
2014-05-15ctrl: Reduce code duplication and add a define to create the structHolger Hans Peter Freyther1-13/+10
This has been pointed out by Jacob and removes two more duplicates of the struct. For the unused CTRL_CMD_DEFINE_STRING macro there will be no verify command.
2014-05-15ctrl: Remove the param parameter as it was never used/implementedHolger Hans Peter Freyther3-7/+0
2014-05-15ctrl: Introduce a macro for read-only attributes and use itHolger Hans Peter Freyther2-35/+17
Certain attributes are read-only. Add a macro to make it more easy to define those.
2014-05-15ctrl: Fix handling of missing repliesJacob Erlbeck1-3/+11
Currently, if a CTRL method does not set the reply, an error is logged ("cmd->reply has not been set"). It even complains when the function implementing the command returns CTRL_CMD_HANDLED, where a reply text is not needed. This patch changes the logging level from ERROR to NOTICE. The logging is now only done, when the retry has not been set and the implementation returns either CTRL_CMD_ERROR or CTRL_CMD_REPLY. So in these cases the reply field must be set. This fixes the generation of log messages when doing NAT ctrl command forwarding. Ticket: OW#1177 Sponsored-by: On-Waves ehf

2014-05-09contrib/rtp: Use payload data files directly by gen_rtp_headerJacob Erlbeck1-4/+30
This adds a --frame-size option to read payload binary files with a fixed frame size directly. The file must not contain RTP headers. In addition '--rate' and '--duration' can be used to configure the timing. Sponsored-by: On-Waves ehf
2014-05-09ipa: Fix the compilation of ipaccess-find on FreeBSDNikola Kolev1-0/+5
FreeBSD does not offer the SO_BINDTODEVICE option. The closest thing is the IP_RECVIF option and this is used here now.
2014-05-09bsc: Fix compilation on FreeBSDNikola Kolev1-0/+2
FreeBSD uses POSIX netinet/in.h for representing socket addresses data types. [Holger removed the #ifdef and changed the order of includes to have specific ones first and system includes later]
2014-05-06nat/bsc: Check proto before calling ipaccess_rcvmsg_baseHolger Hans Peter Freyther3-3/+2
The code in the BSC/NAT called ipaccess_rcvmsg_base without checking if the protocol is IPA. This lead the BSC to respond to SCCP messages with an "ID ACK". From a quick look neither the code of ipaccess_rcvmsg_base in OpenBSC nor the copy of libosmo-abis ever checked the protocol header. So this code has been wrong since initially being created in 2010.
2014-05-01db: Fix next fall-out with make distcheckHolger Hans Peter Freyther2-1/+2
2014-04-30db: Fix fall-out with the subscriber removal in the subscriber deletion codeHolger Hans Peter Freyther1-2/+2
The sender_id is gone so the code that attempted to delete SMS didn't work anymore. Delete the SMS based on src_addr or the dest_addr. Fixes: ====================================================================== ERROR: testSubscriberAddRemove (__main__.TestCtrlNITB) ---------------------------------------------------------------------- Traceback (most recent call last): File "tests/ctrl_test_runner.py", line 379, in testSubscriberAddRemove r = self.do_set('subscriber-delete-v1', '2620345') File "tests/ctrl_test_runner.py", line 114, in do_set return self.recv_msgs()[id] KeyError: 1002
2014-04-30Merge branch 'zecke/features/sms-db-changes'Holger Hans Peter Freyther10-71/+351
This branch allows a SMPP user to fully specify the sender id. It requires a change in schema, database migration code and exposed some issues in the libdbi and the sqlite3 driver.
2014-04-30db: Add testcase for the db migration.Holger Hans Peter Freyther6-2/+42
2014-04-30sms: Add code to migrate the database to the new schemaHolger Hans Peter Freyther2-16/+199
This is mostly based on Alexander's migration code. The code adds transaction handling and some sanity checks and cleanups to the code. We made the decision to fork the sms_from_result method and freeze it to that version. This way sms_from_result can move forward without having to deal with legacy.
2014-04-30sms: Do not store received id in the SMS database.Alexander Chemeris1-21/+10
That was a bad idea from the very beginning. A visible result of this is a wrong SMS routing when you change subscriber extensions, while having queued SMS. It's also a very wrong thing from the code layering perspective. I think the next logical step should be to remove "receiver" pointer from the gsm_sms structure into a structure, special for the internal SMS queue.
2014-04-30db: Add testcase for storing/loading/comparing a smsHolger Hans Peter Freyther1-0/+61
Use the already created subscriber, create a sms and read it back from the subscriber.
2014-04-30sms: Kill the sms->sender and use addr/ton/npi throughout the codeHolger Hans Peter Freyther4-35/+42
This is an incompatible database schema change. Store the type of the address in the database for both the sender and the receiver. Currently it is possible to use SMPP to store a SMS and the NPI and TON will be lost on the delivery of the SMS. The schema is changed to make the delivery always use the right NPI/TON. This patch is not ready for the master branch as there is no upgrade path for the HLR yet.
