* Fix VTY documentation error introduced in "bind" VTY port changeHarald Welte2018-12-231-1/+2
| | | | | | | | | In 99ae401e490e60fc07bef7eacc478be7bdcc9f5a we introduced the ability to specify the TCP port to which the VTY should bind. However, the VTY dcumentation wasn't extended accordingly, causing virtually all master build jobs to fail. Change-Id: I54fb0ca0d3a884a64a349b22de70f3d9bd1a6d54
* vty: Make TCP port configurable and introduce telnet_init_defaultHolger Hans Peter Freyther2018-12-232-3/+31
| | | | | | | | | | | | | | | Extend the vty_bind_cmd VTY command to allow to optionally specify a port in addition to the IPv4 address. Introduce telnet_init_default to relieve client code from having to query the bind IPv4 address (and now the TCP port). Instead a client only needs to pass the default TCP port to use. Client code should use it like: int rc = telnet_init_default(ctx, priv, OSMO_VTY_PORT_SGSN); Change-Id: Id5fb2faaf4311bd7284ee870526a6f87b7e260f3

* make 'show rate-counters' show group indexStefan Sperling2018-10-291-1/+1
| | | | | | | | | | | | | | Show each rate counter group's index in the output of the 'show rate-counters' command, to provide some way of telling apart distinct instances of the same rate counter group. This is not a very user-friendly UI because these indices are generated internally by libosmocore and/or applications, so users cannot easily assign meaning to these indices. However, the current rate counter implementation doesn't allow for more. Change-Id: Ieb151239407e4b2f8859fefec8d0670f5ddf908a Related: OS#3674
* stop printing group description in vty_out_rate_ctr_group_fmt()Stefan Sperling2018-10-292-3/+1
| | | | | | | | | | | | | | When vty_out_rate_ctr_group_fmt() prints the description of a counter group, it assumes this description should appear at the beginning of a line. However, the caller might be printing counters in an indented context. So just let the caller worry about printing the group title if necessary (there is currently only one known caller, which is updated in this commit). Note that printing of the group title was an undocumented feature. Change-Id: I2c55cb54e8b7a7c8c6cf72f22287083767ed0201 Related: OS#2660

* vty logging: fix crash when missing 'logging enable'Neels Hofmeyr2018-10-011-0/+8
| | | | | | | | | | | | | | | We must explicitly check the return value of osmo_log_vty2tgt(), or may run into a segfault. I wasn't aware of this and introduced numerous such cases in I36f17c131cc70ce5a1aef62fd9693097de230cd4. Reproduce: on the VTY, do not issue 'logging enable', invoke 'logging level force-all LEVEL' first. Show in logging_vty_test.vty that this situation is now again amended by telling the user that logging was not enabled. Related: OS#3611 Change-Id: Id11702d1801d6654ca5e5a51b597a0d802e2e8dd

* vty: omit HIDDEN from vty referenceNeels Hofmeyr2018-09-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During 'show online help', the XML vty node dump, omit all commands marked HIDDEN. These commands were already hidden from the VTY reference prior to commit I1f18e0e41da4772d092d71261b9e489dc1598923, because of broken/confusing bit and boolean logic mixup. After that commit, HIDDEN commands end up in the doc. So practically, this patch here brings back the status quo of before above commit, even though the previous code clearly "intended" to list HIDDEN commands in the reference but failed to have that effect. AFAICT the complete list of commands currently hidden is: * osmo-bsc: bts/"training_sequence_code <0-7>", * osmo-bsc: ts/"phys_chan_config PCHAN" for uppercase pchans; * osmo-bts: bts/"rtp bind-ip A.B.C.D" which actually says vty_out(vty, "%% rtp bind-ip is now deprecated%s", VTY_NEWLINE); * osmo-sgsn: 'reset sgsn state' used for SGSN testing. Note that the osmo-sgsn build was broken by including hidden commands in the vty reference, since one of its hidden commands had missing doc strings and made osmotestconfig.py signal failure. This would fix that from the hide-hidden-commands angle, and so would osmo-sgsn commit I8b6e8615e409266910f2f76a10ced9ab33e4de91 from the fix-the-doc-strings angle.

* vty reference: fix deprecation bit evaluationNeels Hofmeyr2018-09-241-2/+2
| | | | | | | | | | | In vty_dump_nodes(), make sure the bitwise & is evaluated first. For the deprecation flag (0x1), the practical effect is most likely identical, assuming that the boolean ! operator flips the first bit, so I expect no visible functional difference. It still was confusing and wrong to look at. Related: OS#3584 Change-Id: I1f18e0e41da4772d092d71261b9e489dc1598923

Resurrect the functionality of 'logging level all everything' -- even if it is still deprecated because the name is confusing, it is now just an alias for 'no logging level force-all'. Show in logging_vty_test.vty that we can now again lift the global logging clamp, both with the new commands as well as with the deprecated ones. Also show that 'force-all' is written back properly, if set. Change-Id: I36f17c131cc70ce5a1aef62fd9693097de230cd4

* logging vty: deprecate the 'everything' keywordNeels Hofmeyr2018-09-131-12/+22
| | | | | | | | | | | | | | | | The 'logging level all everything' has not had an effect for some time now. The plan is to bring back its old functionality, but to keep it deprecated and rather define a less confusing name. * Deprecate 'everything'. * Do not write 'everything' during 'write file' or 'show running-config', which we curiously still do until now. BTW, the reason why we need to compose a complete list of categories for the deprecated 'everything' command is explained in detail in the commit log for I3b083f27e3d751ccec258880ae7676e9af959a63 Change-Id: Ib75fedb0572570a61bb34ee729a2af86cf5f16da
* logging vty: rewrite 'logging level' vty cmd generationNeels Hofmeyr2018-09-131-6/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Completely drop the implementations of log_vty_command_{str,description}(). These functions have been public API once, marked as deprecated since c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7 (March 2017). I considered to keep them, or reduce them to useless stubs, but it is quite silly, really. These functions are completely and utterly useless outside of libosmocore. Any program linking these deserves to fail. Re-implement vty logging level command gen, in logging_vty.c. logging.c is simply the wrong place for that. Introduce logging_internal.h to share logging definitions to logging_vty.c without publishing as API. Introduce static gen_logging_level_cmd_strs() to compose a list of category arguments with their descriptions for VTY commands. Use osmo_talloc_asprintf() instead of the previous error prone and chaotic strlen() counting method. Do not dynamically generate log level arguments, just keep static strings. We are super unlikely to ever change the log levels we have. No changes in logging_vty_test.vty: proves that there is no functional change. All of this, besides introducing basic sanity, is cosmetic preparation to be able to re-use the generic command generation code for arbitrary commands with category or level args (for deprecated and new keywords). Rationale: I want to hide 'all' and 'everything' from the VTY command documentation, by means of deprecating. I first tried to simply define a deprecated 'logging level CAT everything' command: logging level (all|rsl|rr|...) (debug|info|notice|error|fatal) logging level CAT everything # <- deprecated and hidden But unfortunately, command matching doesn't work as intended when the CAT argument reflects a valid category; I want it to invoke the deprecated function as soon as the 'everything' keyword follows, but it stays stuck to the "valid" command when the category argument matches an explicit keyword in that list, and will throw an error on the following 'everything' keyword. I.e.: logging level rsl everything % Unknown command # <-- leads to config file parse error logging level unknown_string everything % Ignoring deprecated 'everything' # <-- works only for invalid categories So I need to define 'everything' separately, again with a list of each valid category instead of a generic CAT arg.

* add osmo_str_tolower() and _toupper() with testNeels Hofmeyr2018-09-071-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | We already have osmo_str2lower() and osmo_str2upper(), but these lack: * proper destination buffer bounds checking, * ability to call directly as printf() argument. Deprecate osmo_str2upper() and osmo_str2lower() because of missing bounds checking. Introduce osmo_str_tolower_buf(), osmo_str_toupper_buf() to provide bounds-safe conversion, also able to safely convert a buffer in-place. Introduce osmo_str_tolower(), osmo_str_toupper() that call the above _buf() equivalents using a static buffer[128] and returning the resulting string directly, convenient for direct printing. Possibly truncated but always safe. Add unit tests to utils_test.c. Replace all libosmocore uses of now deprecated osmo_str2lower(). Naming: the ctype.h API is called tolower() and toupper(), so just prepend 'osmo_str_' and don't separate 'to_lower'. Change-Id: Ib0ee1206b9f31d7ba25c31f8008119ac55440797
* log: add 'last' option to 'logging print file'Neels Hofmeyr2018-08-271-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow printing the source file information *after* the log information. Add target->print_filename_pos, log_set_print_filename_pos() and enum log_filename_pos, and the optional 'last' keyword to the 'logging print file' vty command. (An enum in case we want to add other positions later.) Rationale: on log lines, the logging context is usually printed first in the logging text. Without the source file information, this logging context pretty much aligns in an easily readable way. When adding the source file information, each line's logging context info is shifted right by a pretty much random amount and it is hard to spot recurring logging contexts. One solution is to switch off source file info, of course, but that's not an option when actively hacking on bugs and new features. For example, it is unnecessarily hard to spot lchan FSM related log lines in this osmo-bsc log snippet: DRSL NOTICE mgw_endpoint_fsm.c:603 mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Freeing instance DRSL NOTICE fsm.c:381 mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Deallocated DMSC NOTICE mgw_endpoint_fsm.c:603 SUBSCR_CONN(conn0){CLEARING}: Received Event FORGET_MGW_ENDPOINT DCHAN DEBUG lchan_rtp_fsm.c:741 lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED DCHAN DEBUG lchan_rtp_fsm.c:520 lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Freeing instance DCHAN DEBUG fsm.c:381 lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Deallocated DCHAN DEBUG lchan_rtp_fsm.c:520 lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED DCHAN DEBUG lchan_fsm.c:1232 lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: state_chg to WAIT_RF_RELEASE_ACK DRSL NOTICE handover_fsm.c:762 handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Terminating (cause = OSMO_FSM_TERM_REGULAR) DRSL NOTICE handover_fsm.c:762 handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Freeing instance DRSL NOTICE fsm.c:381 handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Deallocated DCHAN DEBUG lchan_fsm.c:1196 lchan(0-0-1-TCH_F-0){WAIT_RF_RELEASE_ACK}: state_chg to BORKEN DCHAN DEBUG lchan_fsm.c:354 lchan(0-0-1-TCH_F-0){BORKEN}: (type=TCH_F) Clearing lchan state DLMGCP DEBUG mgcp_client.c:741 Tx MGCP msg to MGCP GW: 'DLCX 3 2@mgw MGCP 1.0' DLMGCP DEBUG mgcp_client.c:743 Sending msg to MGCP GW size: 66 DRLL NOTICE mgcp_client_fsm.c:422 MGCP_CONN(to-BTS){ST_DLCX_RESP}: Received Event EV_DLCX_RESP Placing the source file info behind the log text makes it much easier to follow, while the source file info is still available: DRSL NOTICE mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Freeing instance (mgw_endpoint_fsm.c:603) DRSL NOTICE mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Deallocated (fsm.c:381) DMSC NOTICE SUBSCR_CONN(conn0){CLEARING}: Received Event FORGET_MGW_ENDPOINT (mgw_endpoint_fsm.c:603) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED (lchan_rtp_fsm.c:741) DCHAN DEBUG lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Freeing instance (lchan_rtp_fsm.c:520) DCHAN DEBUG lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Deallocated (fsm.c:381) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED (lchan_rtp_fsm.c:520) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: state_chg to WAIT_RF_RELEASE_ACK (lchan_fsm.c:1232) DRSL NOTICE handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Terminating (cause = OSMO_FSM_TERM_REGULAR) (handover_fsm.c:745) DRSL NOTICE handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Freeing instance (handover_fsm.c:745) DRSL NOTICE handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Deallocated (fsm.c:381) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RF_RELEASE_ACK}: state_chg to BORKEN (lchan_fsm.c:1196) DCHAN DEBUG lchan(0-0-1-TCH_F-0){BORKEN}: (type=TCH_F) Clearing lchan state (lchan_fsm.c:354) DLMGCP DEBUG Tx MGCP msg to MGCP GW: 'DLCX 3 12@mgw MGCP 1.0' (mgcp_client.c:741) DLMGCP DEBUG Sending msg to MGCP GW size: 67 (mgcp_client.c:743) DRLL NOTICE MGCP_CONN(to-BTS){ST_DLCX_RESP}: Received Event EV_DLCX_RESP (mgcp_client_fsm.c:422) Implementation: for 'last', insert source file info only when an '\n' is found at the end of the log line composition buffer, so that LOGP()...LOGPC() constructs also print source file info only when a log line actually ends.

* vty: fix use-after-free and memleaks in is_cmd_ambiguous()Neels Hofmeyr2018-07-111-20/+43
| | | | | | | | | | | | | | | | | | | | | | | vty_test: add test against ambiguous cmd causing use-after-free and memory leaks. Add this test along with the fix, because the new test triggers the memory use-after-free and leaks, causing build failures. Add cmd_deopt_with_ctx() to allow passing a specific talloc ctx. is_cmd_ambiguous(): keep all cmd_deopt() allocations until the function exits. Add a comment explaining why. Before this, if a command matched an optional "[arg]" with square brackets, we would keep it in local var 'matched', but we would free the string it points to at the end of that loop iteration; upon encountering another match, we would attempt to strcmp against the freed 'matched'. Instead of adding hard-to-read and -verify free/alloc dances to keep the 'matched' accurately freed/non-freed/..., just keep all cmd_deopt() string allocated until done. Needless to say that this should have been implemented on a lower level upon inventing optional args, but at least this is fixing a program crash.

While at it, add a comment explaining why we don't use talloc_asprintf() instead. Change-Id: I7bdc52afe724c1d21f419fe49a6e2ebca9420969

* ensure VTY commands don't segfault if an FSM has no event namesStefan Sperling2018-02-261-4/+8
| | | | | | | | If no event names are defined for an FSM, show a placeholder message which points out the problem instead of segfaulting. Change-Id: I87457945a7b76aa052305c9c531722be1ea0c1d1 Related: OS#3007
* ensure that osmo_fsm vty commands are only installed onceStefan Sperling2018-02-231-0/+12
| | | | | | | | | | | | | | | | | | | | | | There is a desire to install osmo_fsm vty commands automatically in a library context, rather than requiring every application which directly or indirectly uses osmo_fsm to run osmo_fsm_vty_add_cmd(). However, the function install_element_ve() asserts that elements about to be installed have not already been installed. This means we cannot shift responsibility into a library context without first making sure that osmo_fsm commands are only installed once per combined application+library context, because applications won't know which commands any of its libraries has already installed. A simple solution is to use a global flag which is checked by osmo_fsm_vty_add_cmd() before installing osmo_fsm commands, and is set once the commands have been installed. This way, no harm is done if osmo_fsm_vty_add_cmd() is called multiple times. Change-Id: I10b0b1c1c1bf44c3b8eafc465c1ee06ea2590682 Related: OS#2967

* vty: fix 'logging print file' outputNeels Hofmeyr2018-02-061-8/+11
| | | | | | | | | | | | | | In If1bd79026a3c680ccf7587d545d12f7759a998fc, an erratic logging output crept in for an earlier patch state and was merged by accident; fix 'logging print file (0|1|basename)' output. Add value string to map LOG_FILENAME_* enum to VTY args, use for both command evaluation as well as printing the vty config. The default is 'logging print file 1', hence we could omit an output when '1' is chosen. But for clarity, always output the current setting. Change-Id: I1c931bff1f1723aa82bead9dfe548e4cc5b685e0
* logging vty: add 'logging print file (0|1|basename)' cmdNeels Hofmeyr2018-01-191-0/+27
| | | | | | | Add a VTY command that allows configuring the output of source filename. So far, this was not configurable by VTY at all. Change-Id: If1bd79026a3c680ccf7587d545d12f7759a998fc
