* Fix embedded (arm-none-eabi) buildsHarald Welte2018-06-284-0/+26
| | | | | | | | | Due to OS#3360, build testing for arm-none-eabi was unfortunately skipped for a long time. This is a number of fixes that make the compile test pass again. Related: OS#3360 Change-Id: I88e3c8e1a8786ca2a6a023b0d27c74be200a8588
* return error to sender upon bssgp_tlv_parse() failureStefan Sperling2018-06-251-0/+2
| | | | | | | | | | Return "invalid mandatory information" error status to the sender in case bssgp_tlv_parse() failed. To avoid loops, do not respond with an error status to STATUS PDUs which failed parsing. Change-Id: If73719b75a94d6742bdefc9b6572525cb00a96ee Related: OS#3178
* check bssgp_tlv_parse() return code in bssgp_rcvmsg()Stefan Sperling2018-06-251-0/+5
| | | | | | | | | | | 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 Yanitskiy2018-06-112-16/+31
| | | | | | | | | | | | | | 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 Welte2018-06-091-0/+21
| | | | | | | | | | | | | 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.

* GSUP: introduce new messages for SS/USSD payloadsVadim Yanitskiy2018-05-311-0/+15
| | | | | | | | | | | | | | | | | 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 Yanitskiy2018-05-311-0/+16
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | According to the 3GPP TS 04.80, table 2.5 'Release complete', a RELEASE_COMPLETE message may containg optional FACILITY element. Meanwhile, the 0xff byte is used to indicate that there is no decoded message (legacy field). Let's avoid overwriting of a decoded message. Change-Id: I0c85292222749a48ca0c4b2e93f4fa2d61468c18

The code has been used in osmo-bts-trx since June 2017 (change-id I51b19adde14ebb7ef3bb863d45e06243c323e22e), and I'm just renaming and moving it to libosmocore here.

* lapdm: don't enforce contention resolution on SAPI0/DCCHHarald Welte2018-05-091-5/+2
| | | | | | | | | | | | | | | | | | | In Change-Id: I8c2c103cdc7f9a45d7b2080c572f559fc3db58e4 we introduced a check to enforce contention resolution always being used in MS-originated LAPDm establishment on the main DCCH / SAPI0. This is only required after RACH request (IMM.ASS.) and not after a normal assignment command which was sent already via a dedicated channel. Hence, we cannot enforce a strict requirement for contention resolution in those cases. We *could* use the RSL Channel Activation type as a constraint on whether or not to enforce contention-resoluiton-only LAPDm establishment, but this is out of the scope of the LAPDm code but would have to be done inside OsmoBTS.

However, those IEs only maek sense on the SACCH, where we have B4 frame format and where we actually have a L1 header containing related information. Let's make sure to skip those IEs on regular RLL UNIT DATA INDICATION happening on other channel types. Change-Id: I6f13e02192531479287f71de674d17ca2ceabdc6 Closes: OS#3249

* control_if: Avoid heap-use-after-free in osmo_wqueue_bfd_cbPau Espin Pedrol2018-05-041-19/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Imagine following scenario: 1- client connects to CTRL iface, a new conn is created with POLL_READ enabled. 2- A non-related event happens which triggers a TRAP to be sent. As a result, the wqueue for the conn has now enabled POLL_WRITE, and message will be sent next time we go through osmo_main_select(). 3- At the same time, we receive the GET cmd from the CTRL client, which means POLL_READ event will be also triggered next time we call osmo_main_select(). 4- osmo_main_select triggers osmo_wqueue_bfd_cb with both READ/WRITE flags set. 5- The read_cb of wqueue is executed first. The handler closes the CTRL conn for some reason, freeing the osmo_fd struct and returns. 6- osmo_qeueue_bfd_cb keeps using the already freed osmo_fd and calls write_cb.

* gsm_utils: call gnutls_global_init() as constructorAlexander Couzens2018-05-021-0/+19
| | | | | | | | | | gnutls_global_init must be called at least once for gnutls < 3.3.0. It doesn't hurt calling it twice, except a reference counter is increased. gnutls >= 3.3.0 will call it automatic. Fixes: OS#2986 Change-Id: I241b6ae5aa8df13dd78f04658cf0953e9561c9e2
* RSL/LAPDm: Not all RLL message are "transparent"Harald Welte2018-04-191-3/+21
| | | | | | | | | | 3GPP TS 48.058 has a very clear definition of which messages are "transparent" and hence have the T-bit == 1. This is *not* just all RLL messages, but basically only RLL_DATA.{ind,req} and RLL_UNITDATA.{ind,req}. All other messages are non-transparent. Change-Id: I9f83654af189d818563d799bf623325b7fee8e70 Closes: OS#3188

* add gsm0808_cell_{id,id_list}_name() and friendsNeels Hofmeyr2018-04-182-0/+149
| | | | | | | | | | | | | | | | | | | | Provide comprehensive API to obtain string representations of Cell Identifiers and -Lists. Change gsm0808_test.c to use the new functions (which simplifies the output a bit), so that we don't duplicate printing code in gsm0808_test.c, and so that the not-so-trivial printing code is also tested. In gsm0808_test, also test gsm0808_cell_id_list_name_buf()'s return value and truncation behavior. The rationale for gsm0808_cell_id_list_name(), i.e. printing an entire list of cell identifiers, is that even though the maximum is 127 elements, a list of more than a few elements is hardly ever expected in practice (even more than one element isn't actually expected: either "entire BSS" or a single LAC). It is thus useful to log the entire list when it shows up in Paging and Handover. Change-Id: I9b2106805422f96c5cc96ebb9178451355582df3
