2018-05-10dyn TS: be less strict on chan_nr, to allow arbitrary pchan switchesNeels Hofmeyr1-10/+4
To allow switching a dyn TS also between TCH/H <-> TCH/F and anything else, don't thwart RSL messages just because their chan_nr doesn't reflect the current pchan mode. For dyn TS, leave that to message handling. In particular, a TS switch is invoked by a Chan Activ message, in which case the current pchan by definition mismatches the incoming chan_nr's reflected channel type. With this patch, I have tested successful direct TCH/H<->TCH/F switchover on sysmoBTS, with osmo-bsc patch I72d5d833b186b1e1925d513885b405d8c19aa496 (and 'msc'/'codec-list' vty config to change TCH kinds while gprs mode was none).

2018-05-09rsl: Make channel activation fail if encryption algorithm not supportedHarald Welte1-1/+1
The code actually always *wanted* to make lchan activation fail in case we don't support the algorithm, but it failed ot do so. The problem is encr_info2lchan() which uses bts_supports_cipher() to determine if the cipher is supported. However, if bts_supports_cipher() returns 0 (not supported), it uses this value as return value of encr_info2lchan() where '0' means success (standard osmocom convention). This results in channel activation proceeding, which it shouldn't. Change-Id: I46275b8fc2a1a74f68b4cc60e0f64ba226b108cd Related: OS#3254

2018-05-08add/improve various logging around dyn tsNeels Hofmeyr2-10/+22
This logging turned up while I was debugging dynamic timeslots: - OML Set Channel Attributes logging. - a specific dyn TS pchan error. - show pchan and lchan types on CHAN ACT ACK and REL ACK logging. - on RSL message Rx, log the current pchan kind in detail, using gsm_ts_and_pchan_name(). This logs the underlying pchan as well as the current pchan mode a dyn TS is in. - move 2 dyn TS logging from DL1C to DRSL, where all the other dyn ts logging is.

2018-05-08fix RSL Chan Activ Nack messagesNeels Hofmeyr1-6/+4
In early rsl_rx_chan_activ(), do not use rsl_tx_chan_act_acknack() to trigger sending a NACK, instead use rsl_tx_chan_act_nack() directly. Rationale: the previously used rsl_tx_chan_act_acknack() may decide to omit the NACK, particularly based on the lchan->rel_act_kind. lchan->rel_act_kind indicates whether the Chan Release or Activation was explicitly requested via RSL, and thus whether an ACK/NACK should go back to RSL or not. This gets set only late in rsl_rx_chan_activ(). We cannot set it on top, because we need to first establish whether the Chan Activ is permitted or not. In case of early rejection of the Chan Activ, we do not want to modify the lchan state, but merely reply with a NACK, unconditionally. Before this patch, NACKs that rsl_rx_chan_activ() wants to trigger would possibly be not be sent out on RSL, because lchan->rel_act_kind is not explicitly initialized until later.

2018-05-08ignore RSL RF CHAN REL for inactive lchansNeels Hofmeyr1-9/+29
When an RF CHANnel RELease request is received on an already released lchan, there is no "REL NACK" message or similar, we just ACK the release. When ACKing the release, make sure to reflect the same chan_nr that the release was asked for, since the lchan state may actually reflect a different chan_nr. Factor the actual Rel Ack message sending out of rsl_tx_rf_rel_ack(), which makes all sorts of decisions around normal Rel Ack: add static tx_rf_rel_ack(), with chan_nr argument instead of deriving chan_nr from the lchan. Use this to directly ACK an unusual Chan Rel with the chan_nr that came in with the request.

2018-05-05dyn TS: clear TCH state upon reconnecting as PDCHNeels Hofmeyr1-0/+26
For ip.access style TCH/F_PDCH, this fixes switch-back to PDCH in case the TCH use employed encryption. For Osmocom style TCH/F_TCH/H_PDCH, do the same, purely out of sanity. Roughly the same should already be happening during PDCH Chan Activ, but make sure to clear all these fields, so they are cleared even if IEs are missing. From both dyn TS code paths, call new clear_lchan_for_pdch_activ(), which clears the same fields that are normally overwritten by an RSL Chan Activ.

2018-05-05dyn TS: rx_rf_chan_rel: properly mark PDCH rel when no PCU, clarifyNeels Hofmeyr1-4/+7
When the PCU is not connected, we immediately call rsl_tx_rf_rel_ack() because we don't need to wait for a PDCH deactivation. Fix: properly mark rel_act_kind = LCHAN_REL_ACT_PCU to invoke identical behavior as when the PCU were involved. (When the PCU is connected, a PDCH release on an Osmocom style dyn TS causes an actual release of the PDCH TS, and then triggers an rsl_tx_rf_rel_ack() with rel_act_kind == LCHAN_REL_ACT_PCU.) Clarify the code flow: rc == 1 is the special case of no PCU being connected, so have that in a separate if{}. Change-Id: I654b963815b32fcbce050c2e15f3190c97bc259f
2018-05-05dyn TS: fix TCH/F_TCH/H_PDCH: properly record release of PDCH TSNeels Hofmeyr1-0/+2
When a release of PDCH is complete, actually set the dyn.pchan_is to NONE. Failure to do so currently caused errors on activation of an Osmocom style dyn TS as TCH, in the shape of: rsl.c:636 (bts=0,trx=0,ts=2,ss=0) Tx RF CHAN REL ACK rsl.c:164 (bts=0,trx=0,ts=2,pchan=TCH/F_TCH/H_PDCH switching PDCH -> NONE) RSL rx DCHAN: mismatching chan_nr=0x12 rsl.c:2611 Rx RSL CHAN_ACTIV for unknown lchan rsl.c:710 0x12: Sending Channel Activated NACK: cause = 0x64 The Tx RF CHAN REL ACK shows that we're through with PDCH release, but the following line showing "chan=TCH/F_TCH/H_PDCH switching PDCH -> NONE" shows that the state still reflects active switching. Thus the DCHAN code decides that the chan_nr = 0x12 reflecting a TCH/H on TS 2 is a mismatch and NACKs the TCH activation. (For ip.access style TCH/F_PDCH, the ts->flags are cleared in ipacc_dyn_pdch_complete()). Related: OS#3235 Change-Id: Ic06c8f0fe82ae8a06afa5defd93a685010687965

2018-04-05fix activation of osmocom-style dynamic PDCH as TCH/F or TCH/HHarald Welte1-0/+2
in change-id Iebd2571726d1284a7431b3f9b23ad3185e832ed1 we introduced tighter validation on whether the requested channel number matches the underlying physical channel configuration. Unfortunately this broke activation of an osmocom-style dynamic PDCH as TCH/F or TCH/H rsl_lchan_lookup already permitted a chan_nr if the dynamic PDCH was already switched to the given TCH mode, or at least the related switching had already been initiated. However, in the case of the bug, the current type is NONE, which means that the compatibility check of rsl_lchan_lookup will fail Let's relax the checks of rsl_lchan_lookup() slightly to permit matching for "ts->dyn.pchan_is == GSM_PCHAN_NONE" cases.

What we remove here is a legacy from sharing this header file with openbsc/osmo-bsc-sccplite, which we stopped to do quite some time ago and hence can remove those parts that are only relevant to the BSC but not to the BTS. Change-Id: Icac1656da68f6a006a28c779e3b563bbdd905b3d
2018-03-13common/main.c: track talloc NULL contexts by defaultVadim Yanitskiy1-0/+3
In order to be able to introspect not only the root application context, but also all other contexts, e.g. allocated within libosmocore or other libraries, let's enable tracking the use of NULL contexts using the corresponding talloc API. In order to obserbe all existing contexts, use the following VTY command: OsmoBTS# show talloc-context all ... Example of usage: OsmoBTS# show talloc-context all brief talloc report on 'null_context' (total 1302808 bytes in 5185 blocks) lapd context contains 129 bytes in 5 blocks struct signal_handler contains 40 bytes in 1 blocks struct pcu_sock_state contains 120 bytes in 1 blocks struct lookup_helper contains 24 bytes in 1 blocks struct signal_handler contains 40 bytes in 1 blocks struct signal_handler contains 40 bytes in 1 blocks abis contains 49065 bytes in 19 blocks struct signal_handler contains 40 bytes in 1 blocks struct signal_handler contains 40 bytes in 1 blocks struct signal_handler contains 40 bytes in 1 blocks vty contains 93690 bytes in 5008 blocks logging contains 2862 bytes in 7 blocks OsmoBTS context contains 1156678 bytes in 137 blocks Change-Id: I5e9381902dace7dfd37f98b657e4697b5afcff96
2018-03-13configure: add --enable-werrorNeels Hofmeyr1-0/+21
Provide a sane means of adding the -Werror compiler flag. Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"', but that actually *overwrites* all the other CFLAGS we might want to have set. Maintain these exceptions from -Werror: a) deprecation (allow upstream to mark deprecation without breaking builds); b) "#warning" pragmas (allow to remind ourselves of errors without breaking builds) As a last configure step before generating the output files, print the complete CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

2018-03-11sysinfo: Fix scheduling of downlink SACCH informationHarald Welte1-2/+4
The existing algorithm (present since 2012!) failed to work in the sole case that only *one* SACCH filling type was present. So if you had your BTS configured to only broadcast SI5, but not broadcast SI5ter, SI6 or any other SACCH filling, it would send the SI5 message only once on a newly-established channel, and never again. The old code was working for more-than-one SACCH filling, as well as for no SACCH filling at all. Let's also add a NOTICE message if there is no SACCH filling available at all. This is highly unusual and definitely a noticeable event. Change-Id: Ica801f9b9c118f00d9e3dc2780b3123e925f59b4 Closes: OS#3057 Related: OS#2963

2018-03-11implement support for 3-digit MNC with leading zerosNeels Hofmeyr3-13/+11
Record the mnc_3_digits flag from SI and pass on via the PCU interface. Instead of changing to e.g. osmo_plmn_id, add the flag separately, and instead of bool use a uint8_t, to not raise any struct packing issues and clarify the flag's size beyond any doubt. Bump the PCU interface version to 9. This is one part of the three identical pcuif_proto.h patches: - I49cd762c3c9d7ee6a82451bdf3ffa2a060767947 (osmo-bts) - I787fed84a7b613158a5618dd5cffafe4e4927234 (osmo-pcu) - I78f30aef7aa224b2e9db54c3a844d8f520b3aee0 (osmo-bsc) Depends: Id2240f7f518494c9df6c8bda52c0d5092f90f221 (libosmocore) Change-Id: I49cd762c3c9d7ee6a82451bdf3ffa2a060767947
