* Enable GnuTLS fallbackMax2017-11-023-5/+36
| | | | | | | | | | | | | | | | On systems with GNU/Linux kernel older than 3.17 (Debian 8 "jessie" for example) the osmo_get_rand_id() would always return failure due to missing getrandom() syscall. To support such systems, let's add fallback code which uses GnuTLS library. It can be disabled explicitly via '--disable-gnutls' option at compile-time, otherwise ./configure will fail if both getrandom() and GnuTLS are not available. When building with '--enable-embedded' the fallback is disabled automatically. Related: OS#1694 Change-Id: Ic77866ce65acf524b768882c751a4f9c0635740b

* Revert "vty: Fix bad use of vector_slot()"Neels Hofmeyr2017-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | The patch seemed sensible, but introduces a segfault when hitting tab on the interactive VTY. Reproduction example: osmo-msc telnet 127.0.0.1 4254 OsmoMSC> enable <TAB> So we need to understand what that line of code actually intends to do. Until then, revert this to avoid the segfault. The segfault happens at: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7bc0894 in cmd_complete_command_real (vline=0x5555558d59e0, vty=0x5555558d57b0, status=0x7fffffffe024) at ../../../../src/libosmocore/src/vty/command.c:1953 1953 if (*(char *)vector_slot(vline, index) == '\0') This reverts commit e9e9e427b78271941a25a63567fc2ec2bb9e4433.

* Move additional libraries to appropriate placeMax2017-10-307-60/+46
| | | | | | | | | | | | | According to https://www.gnu.org/software/automake/manual/automake.html#Libtool-Flags the libraries supposed to be added to *_LDADD or *_LIBADD while *_LDFLAGS should contain additional libtool linking flags. Previously we used both. Let's unify this and move all the libraries into proper automake variable. While at it - also add libosmocore.la for tests to LDADD since all the tests link against it anyway. Change-Id: Ia657a66db75df831421af5df1175a992da5ba80f

* osmo_char2bcd(): Implment hex digits a-f and A-FHarald Welte2017-10-271-1/+8
| | | | | | | | | | | | | | osmo_bcd2char() has always supported both decimal and hex. However, osmo_char2bcd() use to only implement decimal digits. With this patch, it also suppots conversion of hex characters from ASCII to BCD. This would be relevant in cases where somebdoy would want to use 'code 11', 'code 12' or 'ST' signals in any addresses (SCCP GT e.g.) Change-Id: I7bbcc6de08024567ab64765c12d7de71df787a7a

| | | | | | | | | In Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 we introduce name mangling to replace any '.' in counter (group) names to be converted to ':'. Let's test for this functionality explicitly as part of the stats_test. Change-Id: Ie35682aa79526e2ffeab6995cd640b7847d855bf

* rate_ctr: Enforce counter (and ctr_group) names are valid identifiersHarald Welte2017-10-244-45/+161
| | | | | | | | | | | | | | As rate counters are automatically exposed on the CTRL interface, we need to make sure they don't contain special characters such as '.' which are not permitted/supported by CTRL. In order to be able to run old versions of osmocom programs with libosmocore versions after this commit, we introduce some special name mangling: Any '.' in the names are replaced with ':' during counter group registration, if valid identifiers can be obtained this way.

* fsm: Enforce FSM and FSM instance names are valid osmocom identifiersHarald Welte2017-10-241-1/+12
| | | | | | | | | Let's enforce that the names of FSMs and their instances are valid osmocom identifiers. This is important as the FSMs are automatically exported via those names on the CTRL inteface, and we have to make sure CTRL syntax actually permits them.

* fixups for recent "Cleanup jenkins build scripts"Neels Hofmeyr2017-10-243-22/+43
| | | | | | | | | | | | | | | Change I24e500e132f5c8e8133d35548cb7b4e4552331d0 was merged, but IMHO needs improvement. Fix these: - clean the git source tree before each build step, in common prep_build(). - fix indenting inside the build() macros. - change build() arg to be build_dir, to absorb cleanup steps into build(). - in jenkins.sh, use $ENABLE_SANITIZE as global env, not passed as arg. - in jenkins.sh, don't do 'make distcheck' twice. It is not necessary to do it from source tree as well as separately from source tree, since distcheck already moves to a different build dir. Change-Id: I09d306350602f21943d5bd45f7388c83ede9b524
* contrib/fsm-to-dot.py: some tweaks that help with osmo-bsc's new FSMsNeels Hofmeyr2017-10-241-13/+40
| | | | | | | | | | | | | | | | | | | | | | Combine the C source file name and the string name into the fsm's internal name token, and use it in most places instead of the plain struct name: osmo-bsc's new FSMs have identical struct names in each static c context. Output in a file name that includes all of these more detailed name tokens. Also parse '(1 << EVENT)' as event names. Note that besides this patch, there are also some tweaks to the osmo-bsc patch that improve the fsm-to-dot experience... - call fsm-to-dot for single files to avoid name conflicts, or rename each struct as a unique name. - Add comments for the event name a callback is intended for, so that not all transitions are interpreted as TEARDOWN (because it is invoked in common error handling, which causes the script to interpret it as the causing event). (or change the event-checking if into a switch that names the valid event and has a default case for all others.) Change-Id: Ib60df7fd19efc99ba9fe797f14c0e3239c4bea20

* add osmo_talloc_asprintf() and ctrl_cmd_reply_printf()Neels Hofmeyr2017-10-242-0/+21
| | | | | | | | | | | | | | | | Add macro to append to a CTRL commands' reply string, ctrl_cmd_reply_printf(). The talloc_asprintf() part of it is generic enough to qualify for a separate macro, osmo_talloc_asprintf(). The idea is to not have to decide for each bit added to a string whether the string is already allocated or not, but simply be able to issue printf commands and let the macro worry about initial allocation or reallocation. This originally came from osmo-hlr change I1bd62ae0d4eefde7e1517db15a2155640a1bab58, where it was requested to move this bit to libosmocore. Change-Id: Ic9dba0e4a1eb5a7dc3cee2f181b9024ed4fc7005

* gb: optionally allow nsip packets only from a specific hostPhilipp Maier2017-10-243-3/+28
| | | | | | | | | | | | | | When listening for nsip connections is enabled, then every remote host may send packets. This is useful for an SGSN that serves multiple PCUs, but contraproductive for a PCU that awaits packets from a single SGSN. Add struct members remote_ip, and remote_port to struct gprs_ns_inst, when set, then the listening end uses connect() to ensure that only the expected host may send packets.

* Replace bitvec_set_uint() with bitvec_set_u64()Max2017-10-242-9/+28
| | | | | | | | | | | | | | | | | | | Old bitvec_set_uint() uses "unsigned int" as input parameter which length is not guaranteed. It does not allow to specify which bit_value to set and does not check for incorrect length. Overall this makes it harder to re-use and more error-prone. Let's replace it with extended implementation which uses fixed type length parameters and extra checks. The additional parameter allows caller to explicitly indicate the need to use L/H instead of 0/1 for bit vector elements. It's necessary to properly encode some of the messages from 3GPP TS 44.018, for example §10.5.2.16 IA Rest Octets. The old function is left for backward compatibility as a tiny wrapper around new function and will be deprecated in follow-up patches.

* ctrl: allow more nodes than those in enum ctrl_node_typeNeels Hofmeyr2017-10-232-14/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | Add ctrl_interface_setup_dynip2() to add a node_count parameter, which can be used to define more ctrl nodes without having to merge a patch to libosmocore. In consequence, also add ctrl_handle_alloc2(), since ctrl_interface_setup_dynip() uses ctrl_handle_alloc() to allocate the node slots, and add node_count param to static ctrl_init(). Passing zero as node_count indicates to use the default of _LAST_CTRL_NODE as before, i.e. to not define more ctrl nodes. Assert that we never allocate less than _LAST_CTRL_NODE slots. The current ctrl_interface_setup_dynip() and ctrl_handle_alloc() become simple wrappers that pass zero as node_count. Their use is still valid and they do not need to be deprecated. The API comment to ctrl_interface_setup_dynip2() explains how to define more node IDs. This patch was verified to work by osmo-hlr.git change I98ee6a06b3aa6a67adb868e0b63b0e04eb42eb50 which adds two node IDs for use by osmo-hlr only. Change-Id: I1bd62ae0d4eefde7e1517db15a2155640a1bab58
