2018-10-30gsm0808: cosmetic: rename parameter "reason" to "cause"Philipp Maier1-1/+1
The function that generates the clear command takes a parameter "reason", which is the cause code. Lets give it the name "cause" to have a coherent naming scheme that matches the other functions and the 3gpp specs. Change-Id: I7b6c15e8fa8db13deef5041095944ca1c58fb99f

2018-04-10deprecate PLMN de-/coding functions incapable of 3-digit MNC with leading zerosNeels Hofmeyr1-3/+4
All our projects have seen patches to move to 3-digit MNC handling. Furthermore, since our builds no longer break from deprecation warnings, I shall no longer refrain from deprecating old API. Change-Id: I55dfaf7ce74870de44120b26c42d45bb7b184341

2018-03-13support for more cell ID list types in libosmocoreStefan Sperling1-1/+6
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'.

2018-02-28implement support for 3-digit MNC with leading zerosNeels Hofmeyr1-0/+4
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.

2017-06-23doxygen: unify use of \file across the boardNeels Hofmeyr1-1/+3
Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).
