2014-10-09gprs-ns: Let gprs_nsvc_reset return a valueJacob Erlbeck2-3/+8
Currently gprs_nsvc_reset does not return any value. This patch changes the function to return an integer, where a value less than zero indicates an error. The value is taken from the gprs_ns_tx_reset function. In case of failure, an error message is logged. Sponsored-by: On-Waves ehf
2014-10-09gprs-ns/test: Add test_sgsn_reset_invalid_stateJacob Erlbeck2-0/+163
This tests the behaviour for a certain combination of messages and packet losses that can put the NS-VC object into an undefined state. In that state, the peer's ALIVE messages are properly answered, but the local test procedure has stopped, incoming unitdata PDUs are answered by STATUS(NS-VC blocked) and the unblocking procedure is not initiated. Ticket: OW#1312 Sponsored-by: On-Waves ehf
2014-10-09gprs-ns/test: Add expire_nsvc_timerJacob Erlbeck1-0/+15
This function forces the expiration of the timer within struct gprs_nsvc. It is meant to be used for controlled (and faster) timer expiration in unit tests. The timer_mode of the expired timer is returned (or -1 if the timer wasn't active). Sponsored-by: On-Waves ehf
2014-10-09gprs-ns/test: Save the last PDU type sentJacob Erlbeck1-0/+4
This records the PDU type of the last message sent to the remote peer in the global variable sent_pdu_type, which can then be used in assertions. Note that sent_pdu_type will remain unchanged if no message has been sent via sendto. Sponsored-by: On-Waves ehf
2014-10-09gprs-ns/test: Use gprs_nsvc_reset instead of gprs_ns_tx_resetJacob Erlbeck2-22/+13
Currently gprs_ns_tx_reset is used to let the NS stack generate NS_RESET message. This is not adjusting the nsvc state properly. This patch uses gprs_nsvc_reset instead which starts the full reset procedure. Sponsored-by: On-Waves ehf

CC msgfile_test.o msgfile/msgfile_test.c: In function "main": msgfile/msgfile_test.c:48:2: warning: implicit declaration of function "talloc_free" [-Wimplicit-function-declaration] talloc_free(entries); ^
2014-10-03build: fix linker error with kasumi_testJan Engelhardt1-2/+1
When the osmocore package is configured with --disable-static, building of kasumi_test fails. This seems quite legit, given the function _kasumi_kgcore is not exported. Don't try to workaround the build system. Include the code. CCLD kasumi/kasumi_test kasumi_test.o: In function `test_expansion': ~tests/kasumi/kasumi_test.c:25: undefined reference to `_kasumi_key_expand' kasumi_test.o: In function `main': ~tests/kasumi/kasumi_test.c:56: undefined reference to `_kasumi' ~tests/kasumi/kasumi_test.c:100: undefined reference to `_kasumi_key_expand' ~tests/kasumi/kasumi_test.c:112: undefined reference to `_kasumi_kgcore' [...]
2014-10-03build: remove unused all_includes and use AM_CPPFLAGSJan Engelhardt8-8/+14
Preprocessor flags are best placed in AM_CPPFLAGS. Remove use of the unused all_includes variable, which is never set.
2014-10-03utils: resolve compiler warnings on implicit declarationsJan Engelhardt1-0/+1

2014-09-25misc: Look into the build directory for generated filesHolger Hans Peter Freyther4-4/+4
the bits/crc files are not inside the sourcedirectory but will end in the build directory. Go and look there as well. This somehow doesn't fail with make distcheck but when building for Yocto Dizzy.
2014-09-23gprs: Set bssgph field in bssgp_msgb_alloc()Jacob Erlbeck1-1/+3
Currently the bssgph field is not set when using the bssgp_tx_* functions. This hinders unit testing of generated messages. This patch initializes the bssgph field directly after allocation a new bssgp msgb in bssgp_msgb_alloc() so that it is set by default. Sponsored-by: On-Waves ehf
2014-09-23gprs: Fix bssgp_rcvmsg to handle signalling msgs with BVCI IEJacob Erlbeck1-3/+7
Currently BSSGP messages with an NS BVCI of 0 (signalling) are discarded if they aren't RESET messages. Thus valid signalling messages (e.g. BLOCK) are not handled properly, because the BVCI IE is ignored if it present. Instead a STATUS message referring to BVCI 0 (instead of the BVCI used in the BLOCK message) is returned. This patch changes the implementation to use the BVCI contained in the BVCI IE if that is present in a signalling message. It fixes BSSGP BLOCK/UNBLOCK for the osmo-sgsn. Note that signalling messages without an BVCI IE (e.g. SUSPEND/RESUME) are still rejected. Ticket: OW#1205 Sponsored-by: On-Waves ehf
2014-09-23gprs: Fix and check BVCI in BSSGP STATUS messagesJacob Erlbeck2-1/+15
Currently the BVCI is not set in all invocations to bssgp_tx_status() when the cause is UNKNOWN_BVCI. This patch adds the argument where it is missing. It also adds a check for compliance (GSM 08.18, 10.4.14.1) to bssgp_tx_status() to emit errors when the following requirement is not fulfilled: The BVCI must be included if (and only if) the cause is either "BVCI blocked" or "BVCI unknown".

2014-09-11Fix copyright header in gan.cHarald Welte1-4/+4
When I wrote the gan.c, I used the wrong copyright/license header (AGPLv3+ intead of GPLv2+). This was a mistake and is fixed hereby.
2014-09-11add missing copyright statements to source code filesHarald Welte5-0/+106
Some source code files didn't have the usual copyright and licence statement at their top. I'm adding them baesed on information in the commitlog.

2014-08-25logging: Add ability to save/print current log filtersHarald Welte3-3/+23
This enables the persistent configuration of let's say 'log filter imsi 012345678' for a given log file in the config file.
2014-08-24gsm48.h: define the reserved TMSI in libosmocore, not openbscHarald Welte1-0/+3
2014-08-24add port number 4238 for BTS control interfaceHarald Welte2-0/+2
2014-08-24libctrl: Add support for 'deferred control commands'Harald Welte3-0/+92
Sometimes a control interface command cannot be processed and responded immediately, but we need to process it asynchronously. In order to support this, we introduce the 'ctrl_cmd_def', which represents such a deferred command. It is created by the service implementing the command using ctrl_cmd_def_make(), and a response is later sent using ctrl_cmd_def_send(). ctrl_cmd_def_is_zombie() must be called to handle the case where the control connection has disconnected/died between receiving the command and sending the response.
2014-08-21ctrl: Attempt fix the build on FreeBSD and add include fileHolger Hans Peter Freyther1-0/+1
IPPROTO_TCP is defined in netinet/in.h. Include it and hope the build is fixed for FreeBSD.

2014-08-21Convert recently-introduced header files to #pragma onceHarald Welte3-13/+3
2014-08-21New <osmocom/ctrl/ports.h> file listing tcp ports for CTRL interfaceHarald Welte2-0/+8
2014-08-21rename controlif_setup() to ctrl_interface_setup()Harald Welte2-4/+4
which means that all control interface related functions now have the common ctrl_ prefix.
2014-08-21libctrl: Make two internal helper functions staticHarald Welte1-2/+2
2014-08-21libctrl: Move bulk of control node lookup inti libosmoctrlHarald Welte2-7/+134
The control interface user now only has to register a very short node lookup function callback. This function is optional, and only required if hierarchical command lookup should be supported.
2014-08-21libctrl: remove 'struct gsm_network' referencesHarald Welte2-9/+6
libctrl doesn't need any knowledge about the type of the user-private data that it gets passed upon setup time and includes on callbacks.
2014-08-21libctrl: remove bsc-specific declarationHarald Welte1-1/+0
this was moved by accident when importing the code from openbsc.
2014-08-21libctrl: adopt to recent ipaccess/ipa naming changeHarald Welte1-2/+3
2014-08-21libctrl: autotools build system integrationHarald Welte5-7/+27
Now we actually build the recently-imported libctrl
2014-08-21libctrl: Add DLCTRL as logging context for the control interfaceHarald Welte4-29/+35
... and make libctrl code use it
2014-08-21libctrl: remove reference to bsc_replace_string()Harald Welte2-1/+8
... and rather introduce a general osmo_talloc_replace_string() to libosmocore.
2014-08-21libctrl: Avoid using external tall_bsc_ctxHarald Welte1-6/+6
Instead of using one flat talloc context (and one that is specific to openbsc), we should attach the objects to whatever parent context they are being used in.
2014-08-21libctrl: remove openbsc headers, convert from make_sock to libosmocoreHarald Welte4-23/+14
2014-08-21libctrl: Remove reference to 'DNAT' in favor of 'DCTRL'Harald Welte1-1/+1
2014-08-21libctr: rename/move control interface to libosmocore naming schemeHarald Welte5-0/+0
2014-08-21ctrl: Allow the value to contain spaces. No need to split the stringHolger Hans Peter Freyther1-1/+1
2014-08-21ctrl: Use CTRL_CMD_DEFINE_STRUCT in CTRL_CMD_DEFINE_RANGEHolger Hans Peter Freyther1-6/+1
Jacob pointed out that I didn't convert CTRL_CMD_DEFINE_RANGE. This patch is doing it now.
2014-08-21ctrl: Reduce code duplication and add a define to create the structHolger Hans Peter Freyther1-13/+10
This has been pointed out by Jacob and removes two more duplicates of the struct. For the unused CTRL_CMD_DEFINE_STRING macro there will be no verify command.
2014-08-21ctrl: Remove the param parameter as it was never used/implementedHolger Hans Peter Freyther2-6/+0
2014-08-21ctrl: Introduce a macro for read-only attributes and use itHolger Hans Peter Freyther1-0/+14
Certain attributes are read-only. Add a macro to make it more easy to define those.
2014-08-21ipa: Use enhanced ipa_msg_recv_buffered() to cope with partioned IPA messagesJacob Erlbeck2-1/+7
The old ipa_msg_recv() implementation didn't support partial receive, so IPA connections got disconnected when this happened. This patch adds the handling of the temporary message buffers and uses ipa_msg_recv_buffered(). It has been successfully tested by jerlbeck with osmo-nitb and osmo-bsc. Ticket: OW#768 Sponsored-by: On-Waves ehf
2014-08-21ctrl: Move the lookup into a separate file in preparation for GPRSHolger Hans Peter Freyther3-152/+14
For GPRS the look-up via bts/trx does not make any sense and would introduce bad depdencies for the SGSN. Move the look-up code to a new file and introduce new setup methods.
2014-08-21ctrl: Make it possible to re-use the string get and set routineHolger Hans Peter Freyther1-3/+7
This can be used for the description field that requires some special handling for newlines.
2014-08-21ctrl: Make the int range set, get and verify methods availableHolger Hans Peter Freyther1-4/+12
For the max power reduction we will need to have a different range method. It will need to check if the value is even. Make the set, get and verify methods available through a macro.
