2018-04-23gsm_08_58.h: introduce RSL_IE_ERIC_PAGING_GROUPAlexander Couzens1-0/+1
Ericsson supports a RSL command to page and immediate assign as single command. For paging a MS the BTS must know the paging group. Change-Id: I9194500e307ad69f8da07510bc965a7a5cd82a2a

2018-04-18add gsm0808_cell_{id,id_list}_name() and friendsNeels Hofmeyr2-1/+13
Provide comprehensive API to obtain string representations of Cell Identifiers and -Lists. Change gsm0808_test.c to use the new functions (which simplifies the output a bit), so that we don't duplicate printing code in gsm0808_test.c, and so that the not-so-trivial printing code is also tested. In gsm0808_test, also test gsm0808_cell_id_list_name_buf()'s return value and truncation behavior. The rationale for gsm0808_cell_id_list_name(), i.e. printing an entire list of cell identifiers, is that even though the maximum is 127 elements, a list of more than a few elements is hardly ever expected in practice (even more than one element isn't actually expected: either "entire BSS" or a single LAC). It is thus useful to log the entire list when it shows up in Paging and Handover. Change-Id: I9b2106805422f96c5cc96ebb9178451355582df3
2018-04-18tlv: add TLV_GET() and TLV_GET_MINLEN()Neels Hofmeyr1-0/+21
Rationale: so far we use code like if (TLVP_PRESENT(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS)) { val = TLVP_VAL(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); len = TLVP_LEN(&tp, VERY_L0NG_ENUM_VALUE_NAME_TH4T_NEVER_EMDS); } This is a) very long and b) prone to picking the wrong name one of the three times, which would use the wrong length or val without necessarily being noticed. A safer and shorter, more readable pattern is: struct tlv_p_entry *e = TVLP_GET(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); if (!e) return -ENOENT; hexdump(e->val, e->len); Change-Id: I445de17fc2daa3ab051f5708dd0cc185b23dc048
2018-04-17protocol/gsm_04_08.h: drop incorrect GSM48_PDISC_USSDVadim Yanitskiy1-1/+0
According to the GSM TS 04.07, section "Protocol discriminator", bits 1 to 4 of the first octet of a standard L3 message contain the protocol discriminator IE. Meanwhile, the GSM48_PDISC_USSD represents value 0x11, i.e. 0b10001, that requires 5 bits, and moreover it is not documented anywhere. Let's drop it.

2018-04-13add gsm0808_{enc,dec}_cell_idNeels Hofmeyr1-12/+21
Clarify semantics and micro-optimise for the case of single Cell Identifer IEs. Test in gsm0808_test.c So far we have gsm0808_enc_cell_id_list2(), but there also exist instances of single Cell Identifiers (3GPP TS 48.008 It is possible to decode the same using the cell identifier list API, but this forces the caller to also keep a full struct gsm0808_cell_id_list2 with all its 127 entries around. E.g. for handover, there are two Cell Identifiers (Serving and Target); I'd need two full cell id lists for each, and these would be dynamically allocated for each handover operation, whether it uses them or not.

2018-04-13add tlv_parse2(), capable of multiple instances of the same IENeels Hofmeyr1-0/+3
Allow passing multiple struct tlv_parsed in an array, to allow parsing as many repeated IEs as are expected by the caller. From tlv_parse(), call tlv_parse2() with dec_multiple = 1 to yield the previous behavior. tlv_parse() remains valid API. An example of multiple IEs is the BSSMAP Handover Request, containing Cell Identifier (Serving) and Cell Identifier (Target), both defined by 3GPP TS 48.008 with identical IE tags; both are mandatory.

This will be used by the upcoming neighbor_ident API in osmo-bsc, where the vty interface allows composing neihbor BSS cell identifier lists, and we want to allow adding individual items from individual user commands. It will also be useful to accumulate cell identifiers in case a subscriber sees multiple alternative cells from a neighboring BSS, and we want to pass these on to the MSC in a Handover Required.

2018-04-09add gsm48_reject_value_namesNeels Hofmeyr1-0/+4
There seems to be quite some confusion / overlap between enum gsm48_reject_value, gsm48_gsm_cause and gsm48_gmm_cause. I tried to go with gsm48_gsm_cause_names[], but e.g. GSM48_REJECT_CONGESTION is not represented. Instead of attempting to mix/merge those enums, provide a separate value string array for enum gsm48_reject_value.

2018-04-09add osmo_fsm_inst_update_id_f()Neels Hofmeyr1-0/+1
In the osmo-msc, I would like to set the subscr conn FSM identifier by a string format, to include the type of Complete Layer 3 that is taking place. I could each time talloc a string and free it again. This API is more convenient. From osmo_fsm_inst_update_id(), call osmo_fsm_inst_update_id_f() with "%s" (or pass NULL). Put the name updating into separate static update_name() function to clarify. Adjust the error message for erratic ID: don't say "allocate", it might be from an update. Adjust test expectation.

2018-04-09add osmo_quote_str(),osmo_quote_str_buf() and testNeels Hofmeyr1-0/+2
Rationale: with osmo_escape_str(), you get the escaped contents of the string, but not so graceful handling of NULL strings. The caller needs to quote it, and for NULL strings not quote it. osmo_quote_str() is like osmo_escape_str() but always quotes a non-NULL string, and for a NULL string returns a literal NULL, i.e. it should (tm) give the exact C representation of a string. That's useful in testing, to show exactly what char* situation we have, without jumping through hoops like if (str) printf("\"%s\"", osmo_escape_str(str, -1)); else printf("NULL"); Copy the unit test for osmo_escape_str() and adjust. To indicate that the double quotes are returned by osmo_quote_str(), use single quotes in the test printf()s. I considered allowing to pick the quoting characters by further arguments, but that complicates things: we'd need to escape the quoting characters. Just hardcode double quotes like C.

2018-04-05ctrl: fix deferred commands (and hence fix osmo-bts-sysmo 'clock-info' cmd)Neels Hofmeyr1-0/+3
The CTRL interface has a ctrl_cmd_def_* API that allows deferring a CTRL command reply until later. However, the command handling currently fails to acknowledge this and deallocates the struct ctrl_cmd anyway. Fix: in struct ctrl_cmd, add a defer pointer to be populated by ctrl_cmd_def_make(). A cmd thus marked as deferred is not deallocated at the end of command handling. This fix needs no change in calling code. (Another idea was to return a different code than CTRL_CMD_HANDLED when the command is to be deferred, but that would require adjusting each user of ctrl_cmd_def_make(). The implicit marking is safer and easier.) Show that handling deferred commands is fixed by adjusting the expectations of ctrl_test.c's test_deferred_cmd() and removing the now obsolete exit_early label. One symptom of the breakage is that osmo-bts-sysmo crashes when asked to report a trx's clock-info, which is aggravated by the fact that the sysmobts-mgr does ask osmo-bts-sysmo for a clock-info. The crash appears since Id583b413f8b8bd16e5cf92a8a9e8663903646381 -- it looked like just fixing an obvious memory leak, which it did as shown by the unit test, but deferred ctrl commands actually relied on that leak. Both fixed now. Related: OS#3120 Change-Id: I24232be7dcf7be79f4def91ddc8b8f8005b56318
2018-04-04gsm0480: copy the raw USSD data, its DCS and lengthVadim Yanitskiy1-0/+12
As it was already documented before, the 'ss_request' struct has a rudiment of deprecated 'ussd_request' struct - the 'ussd_text' field. It represents the data either of an INVOKE component, either of a RETURN_RESULT component, encoded as ASCII in case if DCS is 0x0f (i.e. decoded by the code itself), otherwise raw bytes 'as is'. Previously, there was no possibility to distinguish between ASCII and raw bytes with different DCS. Moreover, the payload decoding is not desired in some cases. Let's introduce the new fields, which will carry the raw unmodified payload, its length and DCS (Data Coding Scheme). Change-Id: Ia193d175021e145bb3b131290231f307dbefc64a

2018-03-28fix logging talloc ctx: add osmo_init_logging2()Neels Hofmeyr1-1/+5
Deprecate osmo_init_logging() for the benefit of adding an explicit talloc context argument to new function osmo_init_logging2(). Pass a ctx to log_init() instead of hardcoded NULL. Before now, *all* of our code uses a NULL ctx for logging, which amounts to talloc "leaks" hit by address sanitizer builds on newer gcc (e.g. gcc 7.3.0 on debian 9). This commit helps fixing "leaks" detected in e.g. osmo-bsc unit tests by a sanitize build with gcc (Debian 7.3.0-12) 7.3.0. Change-Id: I216837780e9405fdaec8059c63d10699c695b360

2018-03-13support for more cell ID list types in libosmocoreStefan Sperling4-4/+46
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'.

2018-03-05features: define osmo_bts_*_feature() as static inlinePhilipp Maier1-2/+2
The functions osmo_bts_set_feature() and osmo_bts_has_feature() are currently defined as inline. Since inline is a hinting, the compiler might choose not to inline the function. This eventually leads to linker problems because the function is then defined multiple times. - use "static inline" instead of "inline" only.

2018-03-05gsm23003: add osmo_mcc_from_str()Neels Hofmeyr1-0/+11
I found myself often using osmo_mnc_from_str() to also decode an MCC and be strict about it, but each time I felt the need to comment like "using osmo_mnc_from_str() also for MCC". Rather formalize this properly. Use a static inline function, no need to add more symbols to libosmo-gsm. Change-Id: I020a4f11791c61742a3d795f782805f7b7e8733e

2018-02-28gsm: add osmo_mnc_from_str(), osmo_mnc_cmp(), osmo_plmn_cmp() for 3-digit MNCNeels Hofmeyr1-0/+5
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 Hofmeyr3-1/+23
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.

2018-02-05GSUP: change osmo_gsup_encode() return typeMax1-1/+1
* match return type of osmo_gsup_encode() with osmo_gsup_decode() to allow propagating error to caller * check return value of osmo_gsup_encode() in GSUP test * return errors instead of braking app with aseert Change-Id: Idaa1deecb6d9e15329bd51867b4f6a03357461f0 Related: OS#2864
2018-02-05utils: add helper wrapper for osmo_strlcpy()Max1-0/+3
Add wrapper for osmo_strlcpy() which uses sizeof() to automatically determine buffer's size and use it for GSMTAP logging. This is pretty common use case for osmo_strlcpy() so it's a good idea to save some typing by using generic define. Related: OS#2864 Change-Id: I03d0d3d32a8d572ad573d03c603e14cdc27a3f7b
