* logging: Introduce mutex API to manage log_target in multi-thread envsPau Espin Pedrol2019-10-091-0/+68
| | | | | | | | | | | | | | | | | | | | log_enable_multithread() enables use of locks inside the implementation. Lock use is disabled by default, this way only multi-thread processes need to enable it and suffer related complexity/performance penalties. Locks are required around osmo_log_target_list and items inside it, since targets can be used, modified and deleted by different threads concurrently (for instance, user writing "logging disable" in VTY while another thread is willing to write into that target). Multithread apps and libraries aiming at being used in multithread apps should update their code to use the locks introduced here when containing code iterating over osmo_log_target_list explictly or implicitly by obtaining a log_target (eg. osmo_log_vty2tgt()).

* logging vty: deprecate the 'everything' keywordNeels Hofmeyr2018-09-131-1/+0
| | | | | | | | | | | | | | | | 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 Hofmeyr2018-09-131-161/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* log: add 'last' option to 'logging print file'Neels Hofmeyr2018-08-271-6/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* logging: allow to log only the basename of each sourceNeels Hofmeyr2018-01-191-0/+14
| | | | | | | | | | | In the C API, add another enum log_file_type value, and when set print only the basename of the source file path. Rationale: especially when not building directly in the source dir, the paths to the source files can become rather long. Usually, just the basename of the file is sufficient to identify the source line. Change-Id: If3e4d5fb2066f8bf86e59c82d1752b1a843cf58e
* logging: separate the '<000b>' subsys from filename loggingNeels Hofmeyr2018-01-191-6/+42
| | | | | | | | | | | | | | | | | | | Add a separate flag and API to switch the category-in-hex output: log_set_print_category_hex(). Add log_set_print_filename2() to modify only the print_filename flag. The old log_set_print_filename() function still affects both flags. Explain the rationale in the comment for log_set_print_filename(). There is no need to deprecate log_set_print_filename(); it might cause compiler warnings and break strict builds unnecessarily. Add VTY command 'logging print category-hex (0|1)'. Since there is no VTY command to switch filename output, nothing needs to be adjusted there (a command will be added in a subsequent patch).

* cosmetic: logging: if color is disabled, don't print ""Neels Hofmeyr2018-01-171-5/+6
| | | | | | | | | | | | If color output is disabled, skip the empty snprintf() to (not) clear the ANSI color. Also, no need to use a format string of "%s", just pass the string constant directly.

* fix -Werror build: logging.c: always use literal with snprintfNeels Hofmeyr2018-01-171-1/+1
| | | | | | | | | | | | | | | | | | A recent commit added an snprintf that passes a pointer to a literal directly to snprintf. Since passing pointers to printf formats is a vulnerability in case user supplied data may be passed in the format, modern compilers warn against that, which breaks our -Werror builds. Even though this is just a pointer to a literal, it needs to be an actual literal to make compilers happy. Use printf("%s", c) instead of printf(c). Note that our current build slave's gcc does not enforce that yet, while newer compilers do. logging.c:338:4: warning: format not a string literal and no format arguments [-Wformat-security] ret = snprintf(buf + offset, rem, c_subsys); Change-Id: Ifa4eb8a9fab66dcd987986065351b4a06421f1ec

| | | | | | | | | | | | | | When log_set_use_color() is enabled, color the log category string according to the log level. The log line before and after the log category is printed in the category's configured color. ERROR and FATAL are red, NOTICE is yellow, INFO is green and DEBUG is blue. The default behavior remains unchanged; If color is enabled, the category string will now always be colored in the log level color, not the log category color, and will stand out from the rest of the line.

Accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING". libosmocore will not be backwards-compatible with the few commits from change-id I5c343630020f4b108099696fd96c2111614c8067 up to this one.

* logging: centrally define ctx and filter indexesNeels Hofmeyr2017-02-221-7/+14
| | | | | | | | | | | | | | | | | | | | | | | It is too easy for calling code to use the same filter and context indexes for different filters and structs. For example, openbsc's IMSI filter and libgb's GPRS_BVC filter both fall on index 1 even though there are plenty more indexes to choose from. To alleviate this, have one central definition here, sort of like ports.h does for VTY and CTRL port numbers. Add static asserts to make sure the indexes fit in the available array and bit mask space. Calling code like openbsc.git and osmo-pcu need adjustments and/or should move to using these enum values instead of their local definitions. Taking this opportunity to also prepare for a split of struct gsm_subscriber in openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter index constants for both subscriber types. Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its use by (1 << LOGGING_FILTER_ALL). Change-Id: I5c343630020f4b108099696fd96c2111614c8067

* fix logging: log_set_category_filter() for internal DL* logging catsNeels Hofmeyr2016-12-121-1/+2
| | | | | | | | | | | | | | | | | | In log_set_category_filter(), passing a negative index lead to memory corruption. Particularly dangerous since the internal logging categories have negative values. Fix: apply map_subsys() to interpret negative values as internal logging categories. As a side effect, out-of-bounds logging categories will be mapped to DLGLOBAL instead of being dropped. Fix the expectations in logging_test to match the fixed bug.

* fix logging: out-of-bounds check should end with user categoriesNeels Hofmeyr2016-12-121-0/+5
| | | | | | | | | | | | | To check category bounds, rather use num_cat_user, to redirect all semantically unknown categories to DLGLOBAL. Adjust logging_test expectations accordingly: "(d)" is now also shown. Note: subsys is and needs to be signed, while num_cat* are unsigned. Thus for a negative subsys, 'subsys >= num_cat_user' practically always yields true. Pay close attention to signedness and check upper bound only for positive values.

* fix logging: also catch first out-of-bounds logging catNeels Hofmeyr2016-12-121-1/+3
| | | | | | | | | | In map_subsys(), fix the '>' condition to '>=' for array bounds checking. Also make the bounds checking more strict: after both invocations of subsys_lib2index(), re-check validity of the array index. If the final index is still wrong, which should never happen, exit by assertion. Change-Id: I7ca1a1d47724e40350f1c4dfebe90bad01c965f9
* fix logging: redirection to DLGLOBAL for invalid categoriesNeels Hofmeyr2016-12-121-1/+8
| | | | | | | | | | | For out-of-bounds logging categories, redirect to the proper DLGLOBAL array index instead of returning -1. Adjust test expectation which shows that the bugs tested for are fixed. Note: there are separate bounds checking problems, left for another patch. Change-Id: I6ea9a59e005a22e0305454291714fdb9531c346b
* import oap message parsing / encoding from openbsc.git; AGPL->GPLHarald Welte2016-12-111-0/+5
| | | | | | | | | | | | | | | | | | | In the process, also: * Change the license from AGPLv3 to GPLv2-or-later; * correct spelling of 'sysmocom' to lowercase; * add '2016' to the copyright; * rename to osmo_*; * add API docs; * add logging category DLOAP: define id and add to internal_cat; * redirect all oap.c logging to DLOAP. A unit test will follow in a subsequent patch, since it needs a minor tweak for decoding of boolean values. The related openbsc change-id is I2f06aaa6eb54eafa860cfed8e72e41d82ff1c4cf.
