* fsm: guard action callbackPhilipp Maier2018-05-151-1/+3
| | | | | | | | | | | The FSM allows to set individual action callback functions for each state but it does not allow to leave the action callback pointer unpopulated. However, there are cornercases where having no callback function is desirable. - Check if action callback is popolated before executing it. Change-Id: I36d221c973d3890721ef1d376fb9be82c4311378

* Add osmo_timerfd_* functions for osmo_fd-wrapped timerfdHarald Welte2018-05-103-1/+74
| | | | | | | | | | | | | | | Linux offers file descriptor based periodic (interval) timers, which can achieve a higher precision than our userspace based timers and which can be slave'd to CLOCK_MONOTINIC or other clock sources. Let's add some code for osmo_fd wrapped versions that integrate well with our select() abstraction. 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. After a merge, the osmo-bts implementations can be removed in favor if this one. Change-Id: Ibeffba7c997252c003723bcd5d14122c4ded2fe7
* 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.

* lapdm: send_rslms_rll_l3_ui(): Don't include B4/SACCH IE unless neededHarald Welte2018-05-081-3/+5
| | | | | | | | | | | | | | The RSL_IE_MS_POWER / RSL_IE_TIMING_ADVANCE is how we communicate the SACCH L1 header values on the MS side between LAPDm and L3 (which is a non-standard use of RSL). 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

* define a constant for the max length of called party BCD IEStefan Sperling2018-05-071-0/+1
| | | | | | | | | | | | According to TS 24.008 10.5.4.7 the called party BSC number IE has a maximum length of 43 octets. This length is assumed inside osmo-hlr with a magic number: uint8_t msisdn_enc[43]; /* TODO use constant; TS 24.008 10.5.4.7 */ This change makes libosmocore provide a constant which osmo-hlr can use.

* configure: Check separately for lib implementing dlopen and dlsymPau Espin Pedrol2018-05-043-6/+8
| | | | | | | | | | Sometimes the library probiding dlopen is not the same one providing dlsym. This is the case when compiling with AddressSanitizer enabled. In this case, AC_SEARCH_LIBS([dlopen]...) reports no lib is required, but tests using dlsym still require to link against -ldl. Change-Id: Ic619b0885688066b60c97caf1e2c7e5402c1d9f7
* control_if: Avoid heap-use-after-free in osmo_wqueue_bfd_cbPau Espin Pedrol2018-05-042-22/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. So in step 6 we get a heap-use-after-free catched by AddressSanitizer: 20180424135406115 DLCTRL <0018> control_if.c:506 accept()ed new CTRL connection from (r=10.42.42.1:53910<->l=10.42.42.7:4249) 20180424135406116 DLCTRL <0018> control_cmd.c:378 Command: GET bts.0.oml-connection-state 20180424135406117 DLINP <0013> bts_ipaccess_nanobts.c:417 Identified BTS 1/0/0 20180424135406118 DNM <0005> abis_nm.c:1628 Get Attr (bts=0) 20180424135406118 DNM <0005> abis_nm.c:1628 Get Attr (bts=0) 20180424135406118 DCTRL <000e> osmo_bsc_ctrl.c:158 BTS connection (re)established, sending TRAP. 20180424135406119 DLCTRL <0018> control_if.c:173 close()d CTRL connection (r=10.42.42.1:53910<->l=10.42.42.7:4249) ================================================================= ==12301==ERROR: AddressSanitizer: heap-use-after-free on address 0x611000003e04 at pc 0x7f23091c3a2f bp 0x7ffc0cb73ff0 sp 0x7ffc0cb73fe8 READ of size 4 at 0x611000003e04 thread T0 #0 0x7f23091c3a2e in osmo_wqueue_bfd_cb /home/osmocom-build/jenkins/workspace/osmo-gsm-tester_build-osmo-bsc/libosmocore/src/write_queue.c:65 #1 0x7f23091ad5d8 in osmo_fd_disp_fds /home/osmocom-build/jenkins/workspace/osmo-gsm-tester_build-osmo-bsc/libosmocore/src/select.c:216 #2 0x7f23091ad5d8 in osmo_select_main /home/osmocom-build/jenkins/workspace/osmo-gsm-tester_build-osmo-bsc/libosmocore/src/select.c:256 #3 0x56538bdb7a26 in main /home/osmocom-build/jenkins/workspace/osmo-gsm-tester_build-osmo-bsc/osmo-bsc/src/osmo-bsc/osmo_bsc_main.c:532 #4 0x7f23077532e0 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x202e0) #5 0x56538bdb8999 in _start (/home/jenkins/workspace/osmo-gsm-tester_run-prod/trial-896/inst/osmo-bsc/bin/osmo-bsc+0x259999) Fixes: OS#3206 Change-Id: I84d10caaadcfa6bd46ba8756ca89aa0badcfd2e3

* osmo-release.sh: Always generate entire commit changelogPau Espin Pedrol2018-05-032-19/+13
| | | | | | | | | | | | | | | | | | | | | | | | Before this commit, for library projects (containing LIBVERSION in some Makefile), the entire commit list was not stored into the changelog, but only a few lines from TODO-RELEASE files. This is a bad approach for several reasons. First, because that file was only aimed at containing API/ABI breaks, and not the full relevant changeset (like bugfixes, new features, etc.). Second, because it relies on every developer making API/ABI changes to remember to store the change in there during commit break time. Let's instead always store the entire commit list in changelog, and let's use TODO-RELEASE only as a list of hints for the maintainer to help him evaluate how LIBVERSION needs to be bumped for each library. Other tools such as osmo-abi-check.git can be used to help with the process of decission too. Let's take the opportunity too to only commit stuff already added to the staging area, as it proved easier to manage from my personal experinece making latest releases.

* add gsm0808_cell_{id,id_list}_name() and friendsNeels Hofmeyr2018-04-186-98/+216
| | | | | | | | | | | | | | | | | | | | 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

A safer and shorter, more readable pattern is: struct tlv_p_entry *e = TVLP_GET(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); if (!e) return -ENOENT; hexdump(e->val, e->len); Change-Id: I445de17fc2daa3ab051f5708dd0cc185b23dc048

It is possible to decode the same using the cell identifier list API, but this forces the caller to also keep a full struct gsm0808_cell_id_list2 with all its 127 entries around. E.g. for handover, there are two Cell Identifiers (Serving and Target); I'd need two full cell id lists for each, and these would be dynamically allocated for each handover operation, whether it uses them or not.

* add tlv_parse2(), capable of multiple instances of the same IENeels Hofmeyr2018-04-134-24/+83
| | | | | | | | | | | | | | | Allow passing multiple struct tlv_parsed in an array, to allow parsing as many repeated IEs as are expected by the caller. From tlv_parse(), call tlv_parse2() with dec_multiple = 1 to yield the previous behavior. tlv_parse() remains valid API. An example of multiple IEs is the BSSMAP Handover Request, containing Cell Identifier (Serving) and Cell Identifier (Target), both defined by 3GPP TS 48.008 3.2.2.17 with identical IE tags; both are mandatory.

* add gsm0808_cell_id_list_add() to combine two cell identifier listsNeels Hofmeyr2018-04-135-0/+361
| | | | | | | | | | | | | This will be used by the upcoming neighbor_ident API in osmo-bsc, where the vty interface allows composing neihbor BSS cell identifier lists, and we want to allow adding individual items from individual user commands. It will also be useful to accumulate cell identifiers in case a subscriber sees multiple alternative cells from a neighboring BSS, and we want to pass these on to the MSC in a Handover Required.

* add gsm48_reject_value_namesNeels Hofmeyr2018-04-093-0/+38
| | | | | | | | | | | | | | There seems to be quite some confusion / overlap between enum gsm48_reject_value, gsm48_gsm_cause and gsm48_gmm_cause. I tried to go with gsm48_gsm_cause_names[], but e.g. GSM48_REJECT_CONGESTION is not represented. Instead of attempting to mix/merge those enums, provide a separate value string array for enum gsm48_reject_value. This will be used by osmo-msc's libvlr (refactoring of FSM result handling), I27bf8d68737ff1f8dc6d11fb1eac3d391aab0cb1. Change-Id: I6661f139e68a498fb1bef10c266c2f064b72774a
* add osmo_fsm_inst_update_id_f()Neels Hofmeyr2018-04-094-22/+97
| | | | | | | | | | | | | | | | In the osmo-msc, I would like to set the subscr conn FSM identifier by a string format, to include the type of Complete Layer 3 that is taking place. I could each time talloc a string and free it again. This API is more convenient. From osmo_fsm_inst_update_id(), call osmo_fsm_inst_update_id_f() with "%s" (or pass NULL). Put the name updating into separate static update_name() function to clarify. Adjust the error message for erratic ID: don't say "allocate", it might be from an update. Adjust test expectation.
