2019-05-24abis_rsl: Fix log message about unimplemented common channel msgHarald Welte1-1/+1
The log is about an unimplemented CChan message, not a TRX message. Change-Id: I52bcf1fd79417ee5bfb054456a0b427e174114dd

2019-05-23lcls: Fix MDCX with garbage on LCLS loop breakPau Espin Pedrol1-1/+1
Commit c997ceb750a67baef1a05590febe1c678b287d8f which added initial code did use memset(0) on the structure. However, later commit b407a8aca45ba8f3426003c4960ca8bd5cfe60e5 modifying the code forgot to initialize it, and as a result most of its fields contain garbage. This results in an MDCX with strange/incorrect values sent when LCLS loop breaks, breaking TTCN3 test BSC_Tests_LCLS.TC_lcls_connect_break. Change-Id: Ib1a7d825690db782a5d14f2d8817acf6cb6a52ea

2019-04-23use libosmocore osmo_tdefNeels Hofmeyr17-394/+87
Move the T_defs API to libosmocore as osmo_tdefs: remove the local T_defs API and use libosmocore's osmo_tdef* API instead. The root reason is moving the mgw_endpoint_fsm to libosmo-mgcp-client to be able to use it in osmo-msc for inter-MSC handover. When adding osmo_tdef, the new concept of timer groups was added to the API. It would make sense to apply group names here as well, but do not modify the VTY configuration for timers. The future might bring separate groups (or not). Depends: Ibd6b1ed7f1bd6e1f2e0fde53352055a4468f23e5 (libosmocore) Change-Id: I66674a5d8403d820038762888c846bae10ceac58

2019-04-08Handover Request: also parse Chosen Algorithm IE, pass to lchan activationNeels Hofmeyr1-0/+29
During inter-BSC-incoming, the MSC sends the chosen encryption algorithm in the Handover Request message. Actually parse this Chosen Encryption Algorithm IE. Place the chosen algorithm and the CK into lchan_activate_info->encr so that the new lchan will use the same ciphering on this new BSS as it did on the old BSS.

2019-04-08lchan activation: add explicit encryption info to activationNeels Hofmeyr3-10/+9
For intra-BSC handover, the previous encryption is copied from the old lchan, which of course is not available during inter-BSC handover. Hence the lchan activation info needs to include an explicit encryption information, and we must not rely on the presence of the previous lchan to copy encryption information from. Add struct lchan_activate_info.encr to allow passing encryption info through lchan_activate() without requiring a previous struct gsm_lchan to be present. Instead of copying from the old lchan, always copy encryption info to lchan_activate_info, and during activation, just before sending the Channel Activation, copy the lchan_activate_info.encr to the new lchan. This prepares for upcoming I5b269f50bd2092516bfdf87746196983d3ac49d1 which obtains the encryption information from an intra-BSC-incoming Handover Request message.

This is prone to error, lets make sure that extranous data at the end of a message is ignored by parsing the bssmap length correctly.

2019-03-24avoid use-after-free: on MGW endpoint dealloc, also forget it in conn->ho.*Neels Hofmeyr1-3/+6
With the FORGET_MGW_ENDPOINT event, the MGW endpoint FSM notifies the gscon that it has deallocated and that hence the gscon should forget all references to it (to avoid a use-after-free). Also do this for the endpoint FSM and endpoint ci pointers in the conn->ho.* sub struct. I saw a use-after-free after a Handover Failure message tears down the lchan and MGW endpoint before triggering the handover_fsm.c cleanup code, which also tries to clean up an endpoint CI if it was created for the failed Handover.

2019-03-19AMR: Signal usage of octet-aligned or bandwith-efficient mode to MSCPhilipp Maier2-0/+42
MGCP/SDP provides fmtp parameters in order to signal which of the two available AMR framing modes (octet-aligned or bandwith-efficient) should be used on the link between BSS and core network. osmo-bsc currently does not set up this mode which means that the RTP packets from the BTS are forwared without inspection/modification, which may lead to malfunction when a BTS is using a framing mode that is not supported by the other end. - Add VTY option to setup the framing mode - Generate related fmtp parameters in SDP Depends: osmo-mgw I622c01874b25f5049d4f59eb8157e0ea3cbe16ba Change-Id: If6d40b2407b87aad2227ea7f15533ef01a3771b3 Related OS#3807

2019-03-19lchan_fsm: do not include 12.2k in active set on HR channelsPhilipp Maier1-0/+9
When "Config-NB-Code = 1" is set via the S-bits, then the resulting multirate configuration IE will contain 12.2K. Since the generator function is not aware if the lchan is activated for HR or FR it sets the flag for 12.2k always. We have to add a check here in order to set the 12.2k flag in the IE back to 0 so that the active set contains a set of useable rates.

2019-03-19codec_pref: fix special handling for AMR rate configuration (S15-S0)Philipp Maier1-29/+56
When match_codec_pref() is called and the codec selections from the ASSIGNMENT COMMAND are matched against the interal capabilities, the configurations are checked one by one. When a match is found that match is returned. However, the implementation currently does not check the AMR S15-S0 bits when the actual matching happens. This is done afterwards in case AMR gets picked. Unfortunately if the MSC implementation is not obeying the settings the MSC has previously communicated in the L3 COMPL message we may end up with an S15-S0 configuration that has all rate selection (which eventually end up as active set in RSL) bits set to zero. This is an invalid configuration and should be prevented. Also the handling of the S15-S0 bits should happen as part of the matching so that there is a chance to try the nect codec in the list if AMR is unuseable. Also S15-S0 has one special setting "Config-NB-Code = 1" (S1 = 1). When this bit is set, the four (in HR only three) most common rates are selected into the active set. If there are also other S-bits set besides S1 we should prefer S1 and discard the other bits. - Perform handling of S15-S0 while matching - If S1 is set, prefer this setting and discard all other settings Change-Id: Ie52376b51fe07ed07056e8df2e9557293ff67a78 Related: SYS#4470
