This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "An utility library for Open Source Mobile Communications". The branch, neels/mnc3 has been updated discards a5bae465eafd50657c4e5314d7e14477f23a0e48 (commit) discards b042ef1252d25d6e6513456d56df029472f30cd1 (commit) discards a4f39f52220f6ce560425860da2e64a9fc842d20 (commit) discards 1d118e28c50127d88b8445b9b8c1b4d349dc4ad9 (commit) discards 6c0204d57ff0df3b06a28256ee29152702ebb67f (commit) discards 913d8503a3f705ffb43f43418c245d52a5b1d481 (commit) via fc05404aeb9edb9a6b4b29fcc743d5d395b8be55 (commit) via c64b2c2d196913fde2ae97d748a4276c2c265807 (commit) via 064148308ca41b986613c4764d8032fa5e4fa020 (commit) via 9372368c5b92ca3956cc8370b5730db50aa678d5 (commit) via 11d9c3a3cb0286f2980a17d05642b9d5db95fb4e (commit) via ed6255ecdddd46e087a700cb3d46948c19822773 (commit) This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (a5bae465eafd50657c4e5314d7e14477f23a0e48) \ N -- N -- N (fc05404aeb9edb9a6b4b29fcc743d5d395b8be55) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/libosmocore/commit/?id=fc05404aeb9edb9a6b4b29fcc743… commit fc05404aeb9edb9a6b4b29fcc743d5d395b8be55 Author: Neels Hofmeyr <neels(a)hofmeyr.de> Date: Tue Feb 20 15:14:14 2018 +0100 introduce GSM_MCC_MNC_INVALID 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.

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.)

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(). - osmo_decode_lai(), osmo_generate_lai() 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.
