2018-03-02features: move bts feature related functionality to libosmocorePhilipp Maier5-1/+95
osmo-bsc and osmo-bts share enums and value strings to describe feature data that is exchanged via OML (manufacturer id) on startup. Also the functions to set and get the respecitive bits in the feature bitvectors are in osmo-bsc and osmo-bts. This is a code duplication and should be resolved. - add enum osmo_bts_features (replaces enum gsm_bts_features) - add osmo_bts_features_descs (replaces gsm_bts_features_descs) - add osmo_bts_set_feature (replaces gsm_btsmodel_set_feature) - add osmo_bts_has_feature (replaces gsm_btsmodel_has_feature) Change-Id: Id0c35aef11aa49aa40abe7deef1f9dbd12210776
2018-03-01gsm23003_test: fix: compare members instead of bcmpNeels Hofmeyr1-1/+3
In certain builds (for me a build with no -O2 flag) the recently added gsm23003_test test_mnc_from_str() fails, because bcmp() compares all bytes of sizeof(struct test_mnc_from_str_result), which has valid data for 7 bytes plus one padding byte that may contain arbitrary values. Instead of bcmp(), rather compare the actual members one by one. Change-Id: I28b28457c7b0462c950612fd9b87b5c7181d8bad
2018-03-01introduce GSM_MCC_MNC_INVALIDNeels Hofmeyr1-0/+4
In some cases, we want to mark an unset MCC-MNC. Define uint16-max for this purpose. osmo-bsc code is already doing so with a -1 and using int data types, which will become inconvenient with the new API that handles MCC and MNC as uint16_t. Change-Id: Ieee7add0bd6d94cf84743a49794bbcd38561b72f

2018-02-28gsm: add osmo_mnc_from_str(), osmo_mnc_cmp(), osmo_plmn_cmp() for 3-digit MNCNeels Hofmeyr5-0/+157
osmo_mnc_from_str() preserves leading zeros in the string and is useful for VTY config parsing (osmo-bsc, osmo-msc, osmo-sgsn, osmo-pcu). osmo_{plmn,mnc}_cmp() takes care of the slight intricacy of ignoring the 3-digit flag if the MNC is anyway >99. Will be used by osmo-sgsn.git and osmo-bsc.git. (All current users just care about identical MNC, but a proper cmp doesn't hurt.) Change-Id: Ib7176b1d65a03b76f41f94bc9d3293a8a07d24c6

2018-02-28implement support for 3-digit MNC with leading zerosNeels Hofmeyr15-75/+277
Enable representing three-digit MNC with leading zeros. The MNCs 23 and 023 are actually different; so far we treated both as 23. Re-encode an incoming BCD or string of 023 as it were, i.e. not dropping the leading zero as 23. Break ABI compatibility by changing the size and ordering of structs gprs_ra_id, osmo_plmn_id, osmo_cell_global_id, ... by adding an mnc_3_digits flag. Change ordering in gprs_ra_id because the canonical oder is {Mobile Country Code, Mobile Network Code}, so have the mcc member first. ABI compatibility cannot be maintained for struct gprs_ra_id, since it is a direct member of structs bssgp_bvc_ctx and bssgp_paging_info, and even just adding a flag to the end would cause ABI changes of those structs. Similarly, osmo_plmn_id is a direct member of osmo_location_area_id, and so forth. Add new API to set and read this additional flag to preserve leading zeros: - osmo_plmn_to_bcd(), osmo_plmn_from_bcd() after gsm48_mcc_mnc_to_bcd() and gsm48_mcc_mnc_from_bcd(). - gsm48_decode_lai2(), gsm48_generate_lai2() after gsm48_decode_lai(), gsm48_generate_lai(). - gsm0808_create_layer3_2() after gsm0808_create_layer3() and gsm0808_create_layer3_aoip(). - various osmo_*_name() functions in gsm23003.h (osmo_rai_name() still in gsm48.h close to struct gprs_ra_id definition). The amount and duplication of these may seem a bit overboard, but IMO they do make sense in this way. Though most code will soon see patches unifying the data structures used, in some cases (vty, ctrl) they are required singled out. Without these functions, the formatting ("%0*u", mnc_3_digits ? 3 : 2, mnc) would be duplicated all over our diverse repositories. In various log output, include the leading MNC zeros. Mark one TODO in card_fs_sim.c, I am not sure how to communicate a leading zero to/from a SIM card FS. The focus here is on the core network / BSS. To indicate ABI incompatibility, bump libosmogsm and libosmogb LIBVERSIONs; adjust debian files accordingly. Implementation choices: - The default behavior upon zero-initialization will be the mnc_3_digits flag set to false, which yields exactly the previous behavior. - I decided against packing the mnc with the mnc_3_digits field into a sub-struct because it would immediately break all builds of dependent projects: it would require immediate merging of numerous patches in other repositories, and it would make compiling older code against a newer libosmocore unneccessarily hard.

2018-02-27l1sap: Add fields for higher-precision timing offset valuesHarald Welte1-2/+8
So far, we used quarter-bits across the L1SAP between the hardware/PHY specific part of OsmoBTS and the common part. In order to increase the resolution, let's add fields/members for 1/256th bit. In order to keep ABI and API compatibility, we use a union around the old and new values, so old code will still compile + work withe new libosmocore.

2018-02-27core: Add timespec helper macros and make timer_compat.h publicPau Espin Pedrol2-1/+45
If a monotonic clock must be used, then the clock_gettime API is used which uses timespec structures. Linux systems by default don't provide helpers to calculate time using timespecs, so let's add them here. Let's also make this header public so these helpers can be used in other projects using libosmocore (expected user: libosmo-netif). Change-Id: I45fc993b9bb0a343763238bf463c8640f47b00f1

2018-02-26print BIG FAT ERROR message if osmo_fsm lacks event namesStefan Sperling3-4/+13
Event names are displayed in VTY commands so all FSM should have them. Print an error message if an FSM is registered without event names. We could also return an error code, however at present no caller checks the return value of osmo_fsm_register() so this would be pointless. Add event names to the test FSM and update expected output accordingly. Change-Id: I08b100d62b5c50bf025ef87d31ea39072539cf37 Related: OS#3008
2018-02-26coding: Add BER-reporting RACH decode functionsHarald Welte4-8/+54
For all other decode operations we report the BER, but not for the RACH. This results in osmo-bts-trx not being able to report BER to the higher layers, which is possible on other BTS backends. Let's close this gap by introducing gsm0503_rach_ext_decode_ber() and gsm0503_rach_decode_ber() with the usual n_errors / n_bits_total arguments. Change-Id: I2b1926a37bde860dcfeb0d613eb55a71271928c5

2018-02-23ensure that osmo_fsm vty commands are only installed onceStefan Sperling1-0/+12
There is a desire to install osmo_fsm vty commands automatically in a library context, rather than requiring every application which directly or indirectly uses osmo_fsm to run osmo_fsm_vty_add_cmd(). However, the function install_element_ve() asserts that elements about to be installed have not already been installed. This means we cannot shift responsibility into a library context without first making sure that osmo_fsm commands are only installed once per combined application+library context, because applications won't know which commands any of its libraries has already installed. A simple solution is to use a global flag which is checked by osmo_fsm_vty_add_cmd() before installing osmo_fsm commands, and is set once the commands have been installed. This way, no harm is done if osmo_fsm_vty_add_cmd() is called multiple times. Change-Id: I10b0b1c1c1bf44c3b8eafc465c1ee06ea2590682 Related: OS#2967

2018-02-19fsm: allow graceful exit on FSM terminationPhilipp Maier3-2/+16
The function _osmo_fsm_inst_term() terminates all child FSMs befor it calls fi->fsm_cleanup(). This prevents the cleanup callback to perform last actions on the child FSMs (e.g. osmo_fsm_inst_unlink_parent()). - Since moving the cleanup callack to the beginning of the function would alter the termination behavior and possibly cause malfunction in already existing implementation that use OSMO fsm, a new optional callback that is called immediately at the beginning of the terminatopn process is added.

2018-02-16memleak: fix all libosmocore callers of gsmtap_sendmsg() to free on failureNeels Hofmeyr2-2/+8
gsmtap_sendmsg() does not free the msgb if it returns a failure rc, so the callers must check the rc and free the msg. Change-Id: I7cf64ed9b14247298ed8b4ab8735627f8235a499
2018-02-16memleak: gsmtap_sendmsg(): don't return 0 when no data was writtenNeels Hofmeyr1-1/+1
If less than the msgb size was written by write(), we want to return -EIO. Hence do not return zero when write() wrote zero bytes, return -EIO in that case as well. Previously, if write() returned zero, gsmtap_sendmsg() would return zero *without* freeing the msg, hence neither would the (ideal) caller. So this fixes a corner-case memleak.

2018-02-16gsmtap_sendmsg(): clarify API doc concerning msgb ownershipNeels Hofmeyr1-0/+3
Not freeing on error does enable callers to try to re-send as well, so it is a kind of useful feature, even though I find it likely for callers to either forget about freeing the msg on error or double-free by accident... I considered changing gsmtap_sendmsg() to always free, but since it is public API, I chose to keep and document its current behavior properly instead. We don't know what callers may exist out there.

inline keyword is a hint for the compiler to inline the function, but it's not mandatory.

When running with -O0 it seems the compiler (gcc 7.2.1) decides to use the external linkage but at the same time it seems it's not generating the function symbol. Fix it by explicitly stating that we want to use static linking for this function. coding/coding_test.o: In function `test_xcch': libosmocore/tests/coding/coding_test.c:86: undefined reference to `dump_ubits' libosmocore/tests/coding/coding_test.c:87: undefined reference to `dump_sbits' Change-Id: I18018adec05ce1c2ddbca38653311d74c7454ce8
