* fix parse_cell_id_lac_and_ci_list()Stefan Sperling2018-03-161-6/+7
| | | | | | | | | | | The implementation was entirely broken, reading data from wrong offsets and always writing to the first element of the decoded list. Also, add a new test for this function which found the problems. Change-Id: If0fafbc7171da2a3044bfa9a167208a1afa1c07b Related: OS#2847 Depends: Ife4e485e2b86c6f3321c9700611700115ad247b2

* fix cell identifier decoding in libosmocoreStefan Sperling2018-03-151-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The cell ID list decoder merged in 11a4d9dd91216fe353e94bfdbbab53bc4f891c0d has a bug which was introduced part-way through the review process in gerrit at https://gerrit.osmocom.org/#/c/6509/ When Neels suggested "why not just {...}id_list[MAXLEN] once?" I changed the cell identifier list from a union of arrays to an array of unions. After this change, elements smaller than the largest type in the union were not laid out consecutively in memory anymore. E.g. uint16_t lac values now occur at offsets of sizeof(id_list[0]) instead of offsets of sizeof(uint16_t). The problem is that I forgot to adjust the decoder accordingly, so the decoder writes to the wrong offsets and returns cell identifier lists which appear to contain uninitialized values when read back by API consumers. I found this problem while adding new regression tests to libosmocore to test encoding and decoding. This commit adds one such tests for LAC list decoding, which failed due to the above bug. I plan to write more tests, however because this first test already uncovered a severe issue I chose to submit a fix now and work on additional tests in later commits.

* fix a cell identifier parsing bug in libosmocoreStefan Sperling2018-03-141-2/+2
| | | | | | | | | | | | Global and LAI+LAC cell IDs were being misparsed due to an off-by-one. This code was incorrectly converted from osmo-bsc, where an additional offset of one byte was needed to skip the cell identifier field. In libosmocore, these parsing routines receive a buffer pointer which is already positioned at the start of the cell identifier field.

* support for more cell ID list types in libosmocoreStefan Sperling2018-03-133-5/+292
| | | | | | | | | | | | | | | | | | | | | | | | Introduce gsm0808_dec_cell_id_list2() with supports additional types of cell identifier lists. The new parsing routines are based on similar routines used by the paging code in osmo-bsc's osmo_bsc_bssap.c. Likewise, introduce gsm0808_enc_cell_id_list2() with support for the same additional types of cell identifier lists. The old API using struct gsm0808_cell_id_list is deprecated. The previous definition was insufficient because it assumed that all decoded cell ID types could be represented with a single uint16_t. It was declared in a GSM protocol header (gsm/protocol/gsm_08_08.h) despite being a host-side representation of data in an IE. The only user I am aware of is in osmo-msc, where this struct is used for one local variable. osmo-msc releases >= 1.1.0 make use of this API. While here, fix a small bug in a test: test_gsm0808_enc_dec_cell_id_list_bss() set the cell ID type to 'LAC' but obviously wants to use type 'BSS'.

* features: move bts feature related functionality to libosmocorePhilipp Maier2018-03-023-1/+51
| | | | | | | | | | | | | | | 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
* gsm: add osmo_mnc_from_str(), osmo_mnc_cmp(), osmo_plmn_cmp() for 3-digit MNCNeels Hofmeyr2018-02-282-0/+80
| | | | | | | | | | | 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
* implement support for 3-digit MNC with leading zerosNeels Hofmeyr2018-02-285-59/+241
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gsm0480: fix USSD OCTET STRING length confusionVadim Yanitskiy2018-01-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | According to the GSM 04.80 (version 5.0.0) specification Annex A "Expanded ASN.1 Module "SS-Protocol", the maximum size of a USSD OCTET STRING is 160 bytes. Thus according to ETSI TS 123 038 (version 10.0.0) specification 6.1.2.3 "USSD packing of 7 bit characters", in 160 octets, it's possible to pack (160 * 8) / 7 = 182.8, that is 182 characters. The remaining 6 bits are set to zero. This change defines both mentioned values: - GSM0480_USSD_OCTET_STRING_LEN 160 - GSM0480_USSD_7BIT_STRING_LEN 182 keeping the old MAX_LEN_USSD_STRING 'as is' due to compatibility reasons.

* TLVP_PRESENT() should not return TRUE after tlv_parse() fails.Stefan Sperling2018-01-121-4/+10
| | | | | | | | | | | | If the length provided in the patcket exceeds the buffer length, tlv_parse() returns -2 but leaves tlv.val and tlv.len initializd. Many callers of tlv_parse() do not check its return value, but rely on TLVP_PRESENT() to see if a particular TLV was parsed successfully. By clearing tlv.val and tlv.len we make it less likely that those callers will use an overlong TLV length value. Change-Id: I4dda6938e1650b4bcaac45809a4763f86f5a9794

| | | | | | | | | | | | | | | To send a Ciphering Mode Command, we may need to derive a Kc from UMTS AKA tokens. gsm_milenage() derives Kc from 3G tokens, but also derives an SRES. For SRES, it requires an OPC, which may need to be derived from OP first. All we need is a Kc, so we could feed a zero OPC ... but to simplify the function call for cases where just a Kc is required, separate the c3 function out from gsm_milenage(), as osmo_auth_c3(). Obviously call osmo_auth_c3() from gsm_milenage() (meaning that osmo-hlr's 55.205 derived auc tests still cover exactly that implementation).
