2018-04-09fsm_test: terminate the main loop instead of exit on timeoutNeels Hofmeyr2-2/+7
In fsm_test.c, we have FSM instance cleanup after the select main loop, but we exit(0) in the timer cb; hence the final code is never called. Rather clean up the instance and hence also test that, by using a global flag to exit the main loop upon timeout. Adjust expected stderr output. BTW, in a subsequent commit, I want to move the fsm instance id testing to below the main loop, to more clearly group the tested bits. Change-Id: Ia47811ffcc1bd68d2630c86be7ab98fc1f338773
2018-04-09add osmo_quote_str(),osmo_quote_str_buf() and testNeels Hofmeyr2-0/+88
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.

Ironically, when deprecating osmo_init_logging() in I216837780e9405fdaec8059c63d10699c695b360, I forgot to change the callers within libosmocore itself, i.e. in the various regression tests. Change-Id: Ia36c248f99353d5baaa2533f46a2f60a8579bdf8

2018-04-05ctrl: fix deferred commands (and hence fix osmo-bts-sysmo 'clock-info' cmd)Neels Hofmeyr2-5/+2
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
2018-04-05ctrl: test deferred cmd, show current failureNeels Hofmeyr2-0/+108
Handling a deferred command currently deallocates the struct ctrl_cmd upon exiting the initial command handling, while it should actually stay around for the asynchronous/deferred handling of the ctrl command. Show the current bug by means of a ctrl test. The test will be adjusted to expect the correct result when the bug is fixed in a subsequent commit (I24232be7dcf7be79f4def91ddc8b8f8005b56318).

2018-03-23gsm0808_test: cosmetic: test non-hex MCCNeels Hofmeyr1-6/+6
The test currently sets the MCC by a hex value, which is a weird choice. The MCC gets BCD'd and hence we will see the decimal values 1:1 in the encoded octets as hex digits. Using hex as input obscures that: Right now it sets mcc = 0x123, which is actually 291 in decimal, and we hence see "92 .1" in the expected BCD result. Using 0x124 in the test source actually makes it hard to see where the 0x123 went. Change the MCC to decimal notation (123, 124, 125) and adjust the expected encoded output.

Also, when the memcmp() fails, print hexdumps of expected and actual result for comparison. I needed it to figure out a test failure, might as well keep it.

Since commit bf383a1d83661af26ccd6521c49b655fb22531d4 tlv_parse() will return the first occurrence of a repeated IE. Add a test to verify this behaviour. This test passes with the current code and fails if bf383a1d83661af26ccd6521c49b655fb22531d4 is reverted.

2018-03-15fix cell identifier decoding in libosmocoreStefan Sperling1-0/+37
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.

2018-03-13support for more cell ID list types in libosmocoreStefan Sperling1-25/+22
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'.

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.

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.

2018-01-22tests/ussd: prevent uninitialized memory accessVadim Yanitskiy1-2/+1
Previously an incorrect length value was passed to both gsm_7bit_decode_n_ussd() and gsm_7bit_encode_n_ussd() functions during test_7bit_ussd() execution, due to: octets_written = strlen(decoded); The problem is that a 7-bit encoded string takes less memory than its 8-bit equivalent. So, here strlen() returns one-byte bigger value, that octets_written is. This then causes the uninitialized memory access.

Rationale: The original patch causes osmo-sgsn to crash as soon as the second subscriber attempts to establish an MM context. Of course osmo-sgsn is wrong to a) fail to check a NULL return value and crash and b) to fail to allocate an MM context just because the rate counter group could not be allocated (it still rejects the MM context completely if rate_ctr_group_alloc() fails). Nevertheless, the price we pay for rate counter correctness is, at least in this instance, way too high: osmo-sgsn becomes completely unusable for more than one subscriber. Numerous other places exist where rate_ctr_group_alloc() is called with a constant index number; from a quick grep magic I found these possible breaking points: osmo-sgsn/src/gprs/gb_proxy.c:1431: cfg->ctrg = rate_ctr_group_alloc(tall_bsc_ctx, &global_ctrg_desc, 0); osmo-sgsn/src/gprs/gprs_sgsn.c:139: sgsn->rate_ctrs = rate_ctr_group_alloc(tall_bsc_ctx, &sgsn_ctrg_desc, 0); osmo-sgsn/src/gprs/gprs_sgsn.c:270: ctx->ctrg = rate_ctr_group_alloc(ctx, &mmctx_ctrg_desc, 0); osmo-sgsn/src/gprs/gtphub.c:888: b->counters_io = rate_ctr_group_alloc(osmo_gtphub_ctx, &gtphub_ctrg_io_desc, 0); osmo-bsc/src/libfilter/bsc_msg_acc.c:87: lst->stats = rate_ctr_group_alloc(lst, &bsc_cfg_acc_list_desc, 0); osmo-pcu/src/bts.cpp:228: m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:793: tbf->m_ctrs = rate_ctr_group_alloc(tbf, &tbf_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:879: tbf->m_ul_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_egprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:880: tbf->m_ul_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_gprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:970: tbf->m_dl_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_egprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:977: tbf->m_dl_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_gprs_ctrg_desc, 0); osmo-pcu/src/tbf.cpp:1475: ul_tbf->m_ctrs = rate_ctr_group_alloc(ul_tbf, &tbf_ctrg_desc, 0); osmo-pcu/src/bts.cpp:226: m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 1); We can fix all of these callers and then reconsider returning NULL, but IMO even into the future, rate counter group indexes are not something worth failing to provide service for. For future bugs we should keep the automatic index picking in case of index collisions. We will get an error message barfed and can fix the issue in our own time, while the application remains completely usable, and even the rate counters can still be queried (at wrong indexes, but life is tough).

2017-12-18ctrl: on parse errors, return a detailed message to senderNeels Hofmeyr1-1/+1
The recently added ctrl_cmd_parse2() returns non-NULL cmd with error messages upon parsing errors. In handle_control_read(), use ctrl_cmd_parse2() and send those back to the CTRL command sender as reply. Retain the previous "Command parser error" reply only in case ctrl_cmd_parse2() should return NULL, which shouldn't actually happen at all. Change-Id: Ie35a02555b76913bb12734a76fc40fde7ffb244d
