* jenkins_arch.sh: Accept "arm-none-eabi" as alias for "arm"Harald Welte2018-06-281-1/+1
| | | | | | | | | | The jenkins build job is calling the script using "amd64" and "arm-none-eabi", while the script expects "amd64" and "arm". Let's add "arm-none-eabi" as an alias for "arm". Closes: OS#3360 Change-Id: Idedd4778a63d67cdbf4f4d538bf4a225abb7547a

| | | | | | | | | | | The return code from bssgp_tlv_parse() was not checked for a parsing error. In case of a parsing error the stored return code could have been overwritten later in this function. Explicitly check for a parsing error and log corresponding packets. Change-Id: Id3d7c52ec3df2bcf4efcee0e0b14fe22ef96964e Related: OS#3178

* gsm/gsm0480: refactor and expose gsm0480_parse_facility_ie()Vadim Yanitskiy2018-06-115-16/+81
| | | | | | | | | | | | | | This function can be used when there is only a part of GSM 04.80 message available - Facility IE, e.g. when a message is carried over GSUP/MAP. Let's expose it. Refactoring includes the following: - adding the 'gsm0480_' prefix; - correcting inverted return value; - cosmetic code style changes. Change-Id: I623c39ffbe6cdee65eade8435a2faa04d0da193e

* vty: Add logging_vty_add_deprecated_subsysHarald Welte2018-06-092-0/+22
| | | | | | | | | | | | | This function permits the user to register deprecated log categories, which will ensure that if log categories are removed from a program, old config files will still load. We simply dynamically allocate a cmd_element and install it at CFG_LOG_NODE. Not registering it at VIEW_NODE or ENABLE_NODE ensures that it's not accessible from the interactive VTY, but only from the config file / configure node.

* fsm: Change semantics of LOGPFSML() log-levelHarald Welte2018-06-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The general idea about each osmo_fsm_instance having a separate log-level was to be able to selectively increase/show/enable logging for some FSM instances (e.g. of a particular subscriber) while maintaining normal logging verbosity for all other instances of the same FSM. The introduction of LOGPFSML() in Change-Id If295fdabb3f31a0fd9490d1e0df57794c75ae547 broke that idea, as it would use a compile-time log level, irrespective of the osmo_fsm_inst.log_level setting of the given instance. Let's combine the two: Use the explicit level stated at LOGPFSML(), _unless_ this instance has a higher log_level configured. This way, all FSMs should normally be created with osmo_fsm_inst.log_level == LOGL_DEBUG. At that point LOGPFSM() statements would be rendered at debug level, typically below the threshold of most logging configurations. Code that has explicit higher log levels like LOGPFSML(fi, LOGL_ERROR) would always be printed, as it is an error message. And if we now increase the osmo_fsm_inst.log_level, then even the normal LOGPFSM() statements would suddenly be logged at that higher level, selectively increasing log verbosity - like originally intended.

* GSUP: introduce new messages for SS/USSD payloadsVadim Yanitskiy2018-05-316-1/+87
| | | | | | | | | | | | | | | | | In order to be able to transfer SS/USSD messages via GSUP, this change introduces the following new message types: - OSMO_GSUP_MSGT_PROC_SS_*, and the following new IE: - OSMO_GSUP_SS_INFO_IE which represents an ASN.1 encoded MAP payload coming to/from the mobile station 'as is', without any transcoding.

* GSUP: implement TCAP-like session managementVadim Yanitskiy2018-05-316-1/+58
| | | | | | | | | | | | | | | | | | | | Unlike TCAP/MAP, GSUP is just a transport layer without the dialogue/context. This prevents us from having session based communication, required e.g. for USSD. But we can emulate TCAP dialogue by adding additional IEs, which would allow to relate each message to a particular session. This change introduces the following IEs: - OSMO_GSUP_SESSION_ID_IE, - OSMO_GSUP_SESSION_STATE_IE, which optionally can be used to indicate that the message is related to a session with given ID, and to manage session state, i.e. initiate, continue, and finish.
