* vty/telnet_interface.c: log connection accept() / close() eventsVadim Yanitskiy2019-07-301-0/+12
| | | | | | | | | | | | | | Unfortunately, osmo_sock_get_name_buf() fails in telnet_close_client(): DLGLOBAL INFO telnet_interface.c:130 Closing telnet connection <error-in-getsockname> because getsockname(), getpeername(), and even close() fail with: "Bad file descriptor". This looks like a bug of the existing code. Change-Id: I77b31abfa159d2f269deaa5a08d94b7bbba7d23c
* gsm0808_test: Fix wrong use of memcpPau Espin Pedrol2019-07-301-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | After recent system upgrade, gcc 9.1.0, I started getting gsm0808_test failing locally: Assert failed memcmp(&enc_ct, &dec_ct, sizeof(enc_ct)) == 0 libosmocore/tests/gsm0808/gsm0808_test.c:992 During investigation with gdb, fields of both structures seem to contain same values. However, closer lookup gives some hints on why it fails: (gdb) print memcmp(&enc_ct, &dec_ct, sizeof(enc_ct)) $1 = 85 (gdb) print memcmp(&enc_ct, &dec_ct, 12) $14 = 85 (gdb) print ((uint8_t*)&enc_ct)[11] $15 = 85 'U' (gdb) print ((uint8_t*)&dec_ct)[11] $16 = 0 '\000' So the 12th byte in struct gsm0808_channel_type is basically an alignment padding byte added by the compiler (to align perm_spch_len to 4-byte alignment). Since both compared structs are initialized without memset(0) but using compiler's designated initializers, it seems the compiler decided it's no longer needed to zero the padding byte, making memcp fail in this case. In order to avoid the failure, let's properly check every field instead of using memcp here. Change-Id: I17fe7a0a5dc650f050bba1f47d071be749550729

* vty/telnet_interface.c: avoid unneeded initializationVadim Yanitskiy2019-07-271-1/+1
| | | | | | | | Unconditional initialization follows the structure definition, so there is no need to do it twice. This prevents compiler from warning about potential errors. Change-Id: If9fd2826f132dfa203dda62940d93dbdfcfd92ac

* tell ubsan to ignore SUN_LENEric Wild2019-07-211-0/+3
| | | | | | | | | | | | | ubsan will report undefined behavior due to the SUN_LEN macros interaction with a null pointer, so let's tell ubsan to ignore this function. After carefully reviewing the final publically availlable drafts of the C99,C11 and C18 standards I can confirm that dereferencing null pointers is still undefined behavior, as such ubsan will always warn with absolutely every existing compiler version. Since the sanitizers are periodically synced between llvm and gcc I'm also fairly confident that rebuilding everything with compiler_rt to use the integrated sanitizers would result in the same message. I sincerly hope that this explanation provides to be sufficient, If not I'd be willing to show up at the next llvm dev meeting to provide quotes from actual sanitizer developers to back up these claims.

* cbsp: Introduce osmo_cbsp_errstrHarald Welte2019-07-203-28/+102
| | | | | | | | | | | | | | Rather than having the encoder/decoder library print some log messages in case of encoding/decoding errors, let's provide something akin to 'errno', but with a string instead of a numeric error code. The 'osmo_cbsp_errstr' global variable (if set) contains a human-readable string describing the most recent encoding/decoding error. It exists separately for each thread and hence can be used safely in multi-threaded environments. Change-Id: Id9a5a595a76ba278647aee9470ded213d8464103

* libosmogsm/l1sap.h: extend ph_rach_ind_param with lqual_cbVadim Yanitskiy2019-07-101-0/+1
| | | | | | | | | | | | The link quality, defined by C/I (Carrier-to-Interference) ratio, can be computed from the training sequence of each burst, where we can compare the "ideal" training sequence with the actual training sequence and then express that in cB (centiBels, dB * 10). By analogy with both RSSI and ToA, it can be used to filter out false-positive detections and ghost Access Bursts. Change-Id: Ie2a66ebd040b61d6daf49e04bf8a84d3d64764ee
* Revert "utils.h: require a semi colon after OSMO_ASSERT"Vadim Yanitskiy2019-07-091-2/+2
| | | | | | | | | | | | | This reverts commit 4e284b637943980a405a8c44f2712b749ded428f. Unfortunately, some projects such as OsmoMSC, OsmoBTS and OpenBSC do contain OSMO_ASSERT statements without a semi colon. Thus, this change causes compilation errors when building them. Please note that only the OSMO_ASSERT's definition is reverted, while changes to other files (adding missing semicolons) are kept. Change-Id: I6da4d7397d993f6c1af658cb5ae1e49c92a1b350

| | | | | | | | | This reverts commit b3f94eb39e19366c3458643ee329a73155d46ff8, that unfortunately breaks some projects which call osmo_fsm_register() on DSO load (i.e. using __attribute__((constructor))) before the logging is initialized. Change-Id: Idc6fcce7e946c23d48589b920e309d60aa7b6645

| | | | | | | | | | As suggested by Vadim while reviewing a related fix for ipa_keepalive.c in libosmo-abis (see https://gerrit.osmocom.org/#/c/libosmo-abis/+/13540/), it makes sense to print an error message if anyone registers a FSM that specifies an allstate_action callback but at the same time no events that would ever end up in that callback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a result of discussion we had in [1]. The key idea is that libosmovty should properly auto-complete the commands containing choice, such as the following one: multi0 (one|two|three) [1] If9b0c0d031477ca87786aab5c269d00748e896c8 Right now, sending the following command: (osmo-foo-bar)# multi0 th would basically match the following vector: multi0 three however the resulting argv would be: ["multi0", "th"] Moreover, sending the following command: (osmo-foo-bar)# multi0 t would basically match the following vectors: multi0 two multi0 three because both start from 't', so the resulting argv would be: ["multi0", "t"] which is ambiguous! The expected output is: (osmo-foo-bar)# multi0 th ok argc=1 three (osmo-foo-bar)# multi0 t % Ambiguous command. This is going to be fixed in the follow up patches.
