* Add special 7-bit encoding and decoding functions for USSD codingAndreas Eversberg2013-08-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Handling 7-bit coding is a little different for USSD, as TS 03.38 states: To avoid the situation where the receiving entity confuses 7 binary zero pad bits as the @ character, the carriage return or <CR> character shall be used for padding in this situation [...]. If <CR> is intended to be the last character and the message (including the wanted <CR>) ends on an octet boundary, then another <CR> must be added together with a padding bit 0. The receiving entity will perform the carriage return function twice, but this will not result in misoperation as the definition of <CR> [...] is identical to the definition of <CR><CR>. The receiving entity shall remove the final <CR> character where the message ends on an octet boundary with <CR> as the last character. Jacob has verified the fix with fakeBTS and the wireshark dissector. Fixes: OW#947 Reviewed-by: Jacob Erlbeck <jerlbeck@sysmocom.de>
* encoding: Provide an overload for the gsm_7bit_encode and a simple testHolger Hans Peter Freyther2013-08-081-0/+1
| | | | | | | This is required for encoding the SMS header using the alpha numeric rules. Reviewed-by: Jacob Erlbeck <jerlbeck@sysmocom.de>
* gsm: Try to clarify why we have gsm_septet_encode in the header fileHolger Hans Peter Freyther2013-08-071-0/+1
| | | | | These functions are not meant to be used by applications and are only here for the unit tests. Try to document that.
* utils.h: we need to include utils.h for osmo_generate_backtrace()Harald Welte2013-07-061-0/+2
| | | | | this causes compiler warnings in user code ever since commit 55cf02221f0654a3f48888f3b13766b671a120f0

* Add chan_nr to RACH info at L1SAP interfaceAndreas Eversberg2013-07-061-0/+1

* Add MPH and TCH primitives to layer 1 SAPAndreas Eversberg2013-07-061-3/+72
| | | | | | | | | | | | | In order to control layer 1 via primitives, MPH primitives are required. There is only one (MPH-INFO) primitive defined in TS 04.04 for all control and measurement functions. A type identifier inside this primitive is used to differentiate between different functions. The TCH primitives are used to carry traffic. TCH primitives carry voice or data traffic, whereas PH-DATA primitives carry FACCH data. PH_RTS and TCH_RTS (ready-to-send) primitives are used to poll requests from upper layers.

* gprs_ns: Allow to set the DSCP for the UDP socket.Holger Hans Peter Freyther2013-03-251-0/+1

* utils: Use fprintf to print the assertion and generate a backtraceKaterina Barone-Adesi2013-03-251-1/+2
| | | | | | | | | This is changing the semantic of the assert. The regression tests now either need to check the stderr result, the exit status or print a message when all tests are completed. This is not that bad as the osmo_generate_backtrace is printing to the stdout right now.
* logging: add new log_targets_reopen() functionHarald Welte2013-03-181-0/+1
| | | | | This function will re-open all existing log files in the application, praticularly useful for SIGHUP handlers in case of logrotate

|
* utils: Introduce OSMO_ASSERT in the utils and use it in the unit testsKaterina Barone-Adesi2013-03-091-0/+7
| | | | | The tests should unconditionally assert, regardless of debug settings. This uses the OSMO_ prefix as it's in the global namespace.
* Added a ring buffer log target to store the last N log messages.Katerina Barone-Adesi2013-02-274-0/+105
| | | | | | | The log target can be used via log alarms and show alarms. Why? This feature was proposed/requested at http://openbsc.osmocom.org/trac/wiki/Tasks/ErrorLogTarget All messages use the same amount of space, prioritizing simplicity.
* Revert "Added a ring buffer log target to store the last N log messages."Holger Hans Peter Freyther2013-02-273-103/+0
| | | | | | | I noticed some more issues and it is the easiest to revert and include the fixed version. This reverts commit 73377229bb33ab79682ce4b126a63602d13304ad.

* misc: Doxygen tweaks: fixed some typos and minor errorsKaterina Barone-Adesi2013-02-1510-12/+18
| | | | | Doxygen generates quite a lot of warnings on libosmocore. Some of them are obvious typos - this patch aims to fix such low-hanging fruit.
* abis_nm: add parenthesis for new abis_nm_debugp_foh() macroHarald Welte2013-02-101-3/+3
| | | | without this, we break e.g. the openbsc build...
* turn abis_nm_debugp_foh() into a macroHarald Welte2013-02-101-1/+11
| | | | | | this will avoid printing 'abis_nm.c' as the filename in the log, which is pretty useless during debugging. We want to know where abis_nm_debugp_foh() is being used from, not where it is implemented.
* Add tlvp_val16_unal() / tlvp_val32_unal() to align 16 and 32 bit valuesAndreas Eversberg2012-12-181-0/+24
| | | | | This is required for CPUs < armv6, to access 16 and 32 values at right memory locations.

* smr: Introduce an id and prefix all log messages with SMR(ID)Holger Hans Peter Freyther2012-11-221-1/+2
| | | | | | | | | | When OpenBSC is handling more than one message at a time it is difficult to see which log message belongs to which SMR instance. Introduce a uint64_t id that can be set to the row_id/message_id and prefix all log messages with SMR(ID). This change is ABI and API incompatible with previous versions of libosmogsm.
* smc: Introduce an id and prefix all log messages with SMC(ID)Holger Hans Peter Freyther2012-11-221-1/+2
| | | | | | | | | | | | | | When OpenBSC is handling more than one message at a time it is difficult to see which log message belongs to which SMC. Introduce a uint64_t id that can be set to the row_id/message_id and prefix all log messages with SMC(ID). This change is ABI and API incompatible with previous versions of libosmogsm. Example: SMC(100) instance created SMC(100) message MNSMS-EST-REQ received in state IDLE
* msgb: fix msgb_pull_u*()Steve Markgraf2012-11-141-3/+3
| | | | | | | | msgb_pull returns a pointer to the new begin of the buffer, unlike msgb_get(), where those functions were originally taken from. Signed-off-by: Steve Markgraf <steve@steve-m.de>
* smc: Make it possible to include gsm0411_smc.h as first header fileHolger Hans Peter Freyther2012-11-141-0/+1
| | | | The code embeds the timer so one needs to include the header file.
* Add "extern" keywordsTobias Engel2012-10-271-5/+5
| | | | | Without the "extern" keyword the variables in this header file will be seen as empty definitions when compiled on OSX.
* logging: Make sure to install standard "end" command in VTY nodeHarald Welte2012-10-221-0/+1
| | | | | When you are in the config-log VTY node, you expect "end" to work like in any other sub-node of config.

* vty: Include osmocom/core/utils.h for the value_string structHolger Hans Peter Freyther2012-09-111-0/+1
|
* logging: Introduce a print_filename flag for the logtargetHolger Hans Peter Freyther2012-09-111-0/+3
| | | | | | Introduce a print_filename attribute for each logtarget. Initialize it with 1 to be backward compatible with earlier versions. The bit is taken from an existint bitfield. There were at least six bits left of the byte.
* logging: Mark the log_info_cat pointer as constsHolger Hans Peter Freyther2012-09-111-1/+1
| | | | | | Applications should keep the log area in a static const area. Mark the pointer as const to address compiler warnings in OpenBSC, cast the const away for the osmo_log_info as it is not declared as const.
* Gb: Add functions for sending flow control messages from BSS sideHarald Welte2012-09-101-0/+8

* Gb: Add header file for BSS-side BSSGP functionsHarald Welte2012-09-102-0/+68
| | | | .. not sure how we could have missed that so far.
* msgb: msgb_get() is supposed to get bytes from END, msgb_pull() from HEADHarald Welte2012-09-081-3/+34
| | | | | | msgb_get() has been wrong all the time, despite the documentation being correct. If you've used the broken msgb_get() before, you have to change your code now, sorry.
* BSSGP: make bvc_ctx->fc a dynamic talloc allocationHarald Welte2012-09-071-1/+1
| | | | | this ensures that we can talloc the flow-control queue entries as siblings off the bvc_ctx.
* BSSGP flow-control: various fixesHarald Welte2012-09-071-5/+13
| | | | | | | * add more comments on units of struct members * make sure to parsre FC-BVC message correctly * add error message in case user passes PDU larger than bucket size * add new function to initialize flow control struct
* libosmogb: Port BSSGP flow control from openbsc/laforge/bssgp_fc branchHarald Welte2012-09-071-0/+37
| | | | | | | | This code is supposed to implement the BSSGP flow control algorithm, both for the per-BSS and for the per-MS flow control. The code currently has no test cases, they will come in a separate commit.
