2018-05-10Add osmo_timerfd_* functions for osmo_fd-wrapped timerfdHarald Welte3-1/+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
2018-05-09lapdm: don't enforce contention resolution on SAPI0/DCCHHarald Welte1-5/+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.

2018-05-08lapdm: send_rslms_rll_l3_ui(): Don't include B4/SACCH IE unless neededHarald Welte1-3/+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

2018-05-07define a constant for the max length of called party BCD IEStefan Sperling1-0/+1
According to TS 24.008 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 */ This change makes libosmocore provide a constant which osmo-hlr can use.

2018-05-04configure: Check separately for lib implementing dlopen and dlsymPau Espin Pedrol3-6/+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
2018-05-04control_if: Avoid heap-use-after-free in osmo_wqueue_bfd_cbPau Espin Pedrol2-22/+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=<->l= 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=<->l= ================================================================= ==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

2018-05-03osmo-release.sh: Always generate entire commit changelogPau Espin Pedrol2-19/+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.

2018-04-18add gsm0808_cell_{id,id_list}_name() and friendsNeels Hofmeyr6-98/+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
2018-04-18tlv: add TLV_GET() and TLV_GET_MINLEN()Neels Hofmeyr1-0/+21
Rationale: so far we use code like if (TLVP_PRESENT(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS)) { val = TLVP_VAL(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); len = TLVP_LEN(&tp, VERY_L0NG_ENUM_VALUE_NAME_TH4T_NEVER_EMDS); } This is a) very long and b) prone to picking the wrong name one of the three times, which would use the wrong length or val without necessarily being noticed. 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

2018-04-17protocol/gsm_04_08.h: drop incorrect GSM48_PDISC_USSDVadim Yanitskiy2-2/+0
According to the GSM TS 04.07, section "Protocol discriminator", bits 1 to 4 of the first octet of a standard L3 message contain the protocol discriminator IE. Meanwhile, the GSM48_PDISC_USSD represents value 0x11, i.e. 0b10001, that requires 5 bits, and moreover it is not documented anywhere. Let's drop it.

don't blindly trust the tag-length value in an IPA CCM ID GET message. This could result in a remotely-triggered integer underflow. Change-Id: I4723361e1094b358310541a7dc4c5c921c778a15

2018-04-15test_gsm0808_enc_dec_speech_codec_with_cfg: initialize properlyNeels Hofmeyr1-7/+7
The uninitialized members of enc_sc sporadically hit address sanitizer failure during gsm0808_test, like: ../../../../src/libosmocore/src/gsm/gsm0808_utils.c:187:8: runtime error: load of value 13, which is not a valid value for type '_Bool' ../../../../src/libosmocore/src/gsm/gsm0808_utils.c:191:8: runtime error: load of value 119, which is not a valid value for type '_Bool' How the test survived so long is a mystery to me; as soon as some uninitialized members would by coincidence not be zero, the test should always have failed at OSMO_ASSERT(memcmp(&enc_sc, &dec_sc, sizeof(enc_sc)) == 0).
