2018-04-04use osmo_init_logging2() with proper talloc ctxNeels Hofmeyr15-40/+23
Completely drop bts_log_init(), call osmo_init_logging2() directly instead: all callers of bts_log_init() passed NULL as category string, so all it ever did was call osmo_init_logging(). The bts_log_info is already declared in the .h. Here and there also define a proper talloc root context instead of using NULL. Change-Id: Ic049f77bef74123b95350bcae182a468e0086b9c

2018-03-21l1sap: Avoid assumption that l1sap is at head of msgbPau Espin Pedrol1-11/+15
This assumption used while sending the rx data to gsmtap in l1sap_up was making osmo-bts-virtual crash, since that bts model is allocating the l1sap in the stack rather than inside the msgb. Instead, let's use the assumption that l2h is set correctly in msgb by the bts model lower layer. crash report: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff6234ec3 in __memmove_sse2_unaligned_erms () from /usr/lib/libc.so.6 (gdb) bt 0 0x00007ffff6234ec3 in __memmove_sse2_unaligned_erms () from /usr/lib/libc.so.6 1 0x00007ffff6dbf4c8 in gsmtap_makemsg_ex (type=<optimized out>, arfcn=arfcn@entry=17255, ts=ts@entry=6 '\006', chan_type=<optimized out>, ss=ss@entry=0 '\000', fn=fn@entry=11249, signal_dbm=0 '\000', snr=0 '\000', data=0x5555557d5b50 "", len=4294967263) at libosmocore/src/gsmtap_util.c:179 2 0x00007ffff6dbf6d8 in gsmtap_send_ex (gti=0x555555877f10, type=type@entry=1 '\001', arfcn=arfcn@entry=17255, ts=ts@entry=6 '\006', chan_type=<optimized out>, ss=<optimized out>, fn=11249, signal_dbm=0 '\000', snr=0 '\000', data=0x5555557d5b50 "", len=4294967263) at libosmocore/src/gsmtap_util.c:311 3 0x00007ffff6dbf765 in gsmtap_send (gti=<optimized out>, arfcn=arfcn@entry=17255, ts=ts@entry=6 '\006', chan_type=<optimized out>, ss=<optimized out>, fn=fn@entry=11249, signal_dbm=0 '\000', snr=0 '\000', data=0x5555557d5b50 "", len=4294967263) at libosmocore/src/gsmtap_util.c:330 4 0x0000555555573571 in to_gsmtap (trx=0x7ffff7ef8070, l1sap=0x7fffffffde80) at osmo-bts/src/common/l1sap.c:397 5 0x0000555555573b9c in l1sap_up (trx=0x7ffff7ef8070, l1sap=l1sap@entry=0x7fffffffde80) at osmo-bts/src/common/l1sap.c:1285 6 0x000055555555ec06 in virt_um_rcv_cb (vui=<optimized out>, msg=<optimized out>) at osmo-bts/src/osmo-bts-virtual/l1_if.c:170 7 0x000055555555f5c6 in virt_um_fd_cb (ofd=0x55555587cc30, what=<optimized out>) at osmo-bts/src/osmo-bts-virtual/virtual_um.c:50 8 0x00007ffff6db6991 in osmo_fd_disp_fds (_eset=0x7fffffffe090, _wset=0x7fffffffe010, _rset=0x7fffffffdf90) at libosmocore/src/select.c:216 9 osmo_select_main (polling=polling@entry=0) at libosmocore/src/select.c:256 10 0x0000555555576fbc in bts_main (argc=5, argv=0x7fffffffe288) at osmo-bts/src/common/main.c:364 11 0x00007ffff61b5f4a in __libc_start_main () from /usr/lib/libc.so.6 12 0x000055555555c4ca in _start () In the old code when the sizeof(osmo_phsap_prim) was being substracted it resulted on a negative len which later was casted to unsigned int and became a really big number.

2018-03-17Get rid of 'struct gsm_bts_role_bts'Harald Welte36-477/+371
gsm_bts_role_bts was introduced at a time when we still shared gsm_data_shared.[ch] between BSC and BTS, and where we then subsequently needed a BTS-private structure. Since that sharing was abandoned quite some time ago, we can merge gsm_bts_role_bts into gsm_bts and do away with the bts/btsb dualism in a lot of the code.

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.

2018-03-10sysmobts: Compatibility with older firmware versionsHarald Welte1-1/+12
When using a firmware version < 3.6, the call to l1if_mute_rf() returned an error, which caused an OML CHG ADM STATE NACK. Let's check if the l1if_mute_rf() call is an un-mute for all timeslots (which apparently we do always at start-up). If it is, then acknowledge it even if muting is not supported by earlier firmwares. I suppose the change causing this problem was introduced in: commit b26b8fc77692e851469f3e27b9aeaeff233ffd2e Author: Holger Hans Peter Freyther <zecke@selfish.org> Date: Tue Mar 4 15:03:59 2014 +0100 sysmobts: Do a RF mute at initialization when the RC is locked With the current change applied, we can run the BTS with earlier firmware versions than 3.6.0 again.

SI1 is only required if frequency hopping is used or if NCH is used. So it's optional. If OsmoBTS has no SI1 configured, it will transmit the empty SI1 buffer at TC=0, and as a result no valid SI will be broadcast at TC=0. Change-Id: I41ab885c00e943199b2e939e98f30e267ecffbee Closes: OS#3051
2018-03-08fix handover: handle_ph_ra_ind(): evaluate ra_ind before msgb_trim()Neels Hofmeyr3-97/+118
Commit c2b4c668f3510b7b0baace749c5a310959010e90 I3b989580cb38082e3fd8fc50a11fedda13991092 introduces evaluation of ra_ind members below the msgb_trim() call that actually invalidates ra_ind. A symptom is that it breaks detection of Handover RACH, wich always ends up with lchan == NULL and interpreting all RACH as chan_nr == 0x88. Fix: do all evaluation of ra_ind before the msgb_trim(), for osmo-bts-sysmo, litecell-15 and octphy. To guard against similar mistakes in the future, set ra_ind = NULL before the msgb_trim() call.

In general, RACH bursts should not arrive with negative offset. Let's limit early signal arrival up to 2 symbols, otherwise it is most likely noise, interference or a ghost. TTCN-3 test case: Icccc88545ed3aabd6da28a40599a8a77d1de477d Change-Id: I662294fe3136cf7a259be13816a3e63f7db9a948

Previously, the number of RACH slots with valid non-handover RACH burst was incremented between both BER (Bit Error Rate) and ToA (Timing of Arrival) checks.

2018-02-27Add high-accuracy ToA value to Uplink Measurement ReportsHarald Welte3-0/+41
Normal Abis RSL MEasurement Results contain only the "MS Timing Offset IE" in units of full symbols. In some use cases it is important to have higher-accuracy timing information exposed to the BSC. We do this by adding the average timing offset value during the last measurement interval in 1/256th symbol accuracy to the "Supplementary MEasuremen Information" part of the TS 48.058 9.3.25 Uplink Measurements IE. In order to avoid any compatibility issues, this feature is only enabled if the new vty config command "supp-meas-info toa256" at the bts node is enabled.

2018-02-27L1SAP: Increase resolution of reported burst timingHarald Welte8-19/+19

Let's change L1SAP to use 1/256 bits and hence not loose any resolution.

2018-02-27RACH decoding: Use BER threshold for RACH ghost detectionHarald Welte4-1/+24
When decoding RACH bursts, we should use a BER threshold in order to help distinguish 'ghost' RACH bursts from real RACH bursts. The theoretical ideal threshold according to some papers is 7 out of 41 bits qhich aquals to Eb/N0 of 0 dB = 0.1707 (17.07%) We add a new 'ber10k' parameter to the RACH indication l1sap primitive (needs separate change for libosmocore), and then fill this value from osmo-bts-{sysmo,lc15,trx,octphy}. The common part above L1SAP then applies the threshold, which can be changed from vty using the "max-ber10k-rach <0-10000>" command available at the BTS node. The unit is BER in 1/10000, i.e. a value of 100 equals 1% bit error rate. Change-Id: Ic41c11f6312a36baa2738547e8dcec80829457f8
2018-02-27Move rach_busy counting above L1SAPHarald Welte5-48/+44
In the past, rach_busy counting was performed below L1SAP, while reporting was handled above. This lead to subtle differences between the BTS models, such as osmo-bts-trx missing to increment rach_busy. Let's move the rach_busy counting above L1SAP to share more code. This means we need libosmocore Change-Id I9439810c3a3ad89ea0302753617b850749af887c for the additional required parameters in ph_rach_ind_param, as well as libosmocore Change-id I2b1926a37bde860dcfeb0d613eb55a71271928c5 for osmo-bts-trx to determine the RACH bit error rate.
