2013-08-12debian: Split libosmocore into various libs and address lintian warningsHolger Hans Peter Freyther11-10/+49
Package the various libraries separately. This will allow to install libosmogsm3 and libosmogsm4 in parallel.

2013-08-09lapd: Remove the double NULL check idiom with msgb_freeHolger Hans Peter Freyther1-22/+13
if (ptr) msgb_free(ptr) extends to: if (ptr) talloc_free(ptr) And according to the talloc documentation a talloc_free(NULL) will not crash: "... Likewise, if "ptr" is NULL, then the function will make no modifications and returns -1."

2013-08-09gsm: The LAPDm prim/structs changed, increment current version0.6.3Holger Hans Peter Freyther1-1/+1
2013-08-08ussd: Changed 7bit test to check spec conformance directlyJacob Erlbeck1-6/+13
Renamed gsm_7bit_ussd() to test_7bit_ussd() and extended the function to take the expected binary encoding and eventually added trailing bytes in the re-decoded text as arguments. These are used to check assertions of the right behaviour instead of solely relying on regression data, because the value are determined by the spec and fixed and it is more obvious this way. Especially concerning the case with the duplicated \r which can easily be overlooked when it's only present in the ok file.
2013-08-08Add special 7-bit encoding and decoding functions for USSD codingAndreas Eversberg6-5/+83
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>
2013-08-08encoding: Provide an overload for the gsm_7bit_encode and a simple testHolger Hans Peter Freyther5-2/+28
This is required for encoding the SMS header using the alpha numeric rules. Reviewed-by: Jacob Erlbeck <jerlbeck@sysmocom.de>
2013-08-07gsm: Try to clarify why we have gsm_septet_encode in the header fileHolger Hans Peter Freyther1-0/+1
These functions are not meant to be used by applications and are only here for the unit tests. Try to document that.
2013-08-06vty: Support multi-char separators and end stringsJacob Erlbeck2-5/+6
In vty_cmd_string_from_valstr() include the real string lengths of the sep and end arguments into the buffer size calculation.
2013-08-06vty: Fix misusage of snprintf in vty/utils.cJacob Erlbeck6-4/+71
Compiled with ubuntu 1204 (precise), where -Wformat-security is enabled by -Wall. Test yields ok, but the current implementation doesn't properly support multi-character separators and end strings. So the test output is truncated. Addresses: utils.c: In function 'vty_cmd_string_from_valstr': utils.c:84:2: warning: format not a string literal and no format arguments [-Wformat-security] utils.c:84:2: warning: format not a string literal and no format arguments [-Wformat-security] utils.c:108:2: warning: format not a string literal and no format arguments [-Wformat-security] utils.c:108:2: warning: format not a string literal and no format arguments [-Wformat-security]

2013-07-14vty: Fix logically dead code in the description handlingHolger Hans Peter Freyther1-1/+1
The code most likely wanted to check the result of argv_concat. To do this we need to dereference the dptr. Logically dead code (DEADCODE) dead_error_line: Execution cannot reach this statement "return 1; Fixes: Coverity CID 1040675
2013-07-11gsm0808.c: Add TLV definition for LAYER3_HEADER_INFORMATIONDmitri Soloviev1-0/+1
This is required for osmo-bsc to parse Alcatel S-12 CIPHER MODE COMMAND in osmo-bsc.
2013-07-10LAPD: Free resume/re-establishment msgb if it carries no contentAndreas Eversberg1-2/+5
lapdm.c takes the re-establishment message and forwards it to lapd_core.c, so we can assume that msgb is set at primitive. In case there is data in the re-establishment msg, it is moved into send_buffer. In case of no data (0 length), it must be freed. Fixes an issue spotted by Coverity Scan.
2013-07-07gsm: Revert the gsm_7bit_encode changes as they are wrongHolger Hans Peter Freyther2-30/+9
This reverts commit f996b05dbddccb8e8788dd69777a4fedfa2373eb and 2b0cac4ef83137ee0bdd583aee877eac467abeab. A detailed explanation can be found here: http://lists.osmocom.org/pipermail/openbsc/2013-July/004737.html The short description is that: 1.) The API should return (as out parameter) the number of octets used. 2.) The handling for the <CR> encoding only applies to USSD and it is incomplete. On top of that it broke the SMS test.
2013-07-06make lapd_test compile again.Harald Welte1-69/+0
For whatever reason two functions were present twice in the code, probably some git merge/rebase artefact?
2013-07-06utils.h: we need to include utils.h for osmo_generate_backtrace()Harald Welte1-0/+2

It is used to transfer PHYSICAL INFORMATION message to the MS.
2013-07-06LAPDm: Fix re-establishment of datalinkAndreas Eversberg1-5/+14
If the datalink fails or if handover or assignment to a new channel fails, it is re-establised by sending SABM again. The length of establish message is 0 in this case. The length is used to differentiate between re-establishment and contention resolution, which has to be handled differently. See TS 04.06 Chapter 5.4.2.1
2013-07-06Add chan_nr to RACH info at L1SAP interfaceAndreas Eversberg1-0/+1
The chan_nr is required to locate timeslot and subslot of access bursts during handover procedure.
2013-07-06Add RSSI to l1sapAndreas Eversberg1-0/+2
2013-07-06Add MPH and TCH primitives to layer 1 SAPAndreas Eversberg1-3/+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.

2013-07-04get_value_string: Null terminate after the call to snprintfHolger Hans Peter Freyther1-0/+1
It is impossible that the snprintf will fill the entire namebuf but just follow the idiom to make sure it is null terminated. Related: Coverity CID 1040676
2013-07-03vty: Attempt to fix various meam leaks in the VTY lookup codeHolger Hans Peter Freyther1-0/+3
These routines were not freeing vectors used for the lookup. On review it is fixing another path not detected by coverity. The danger is a double free in tab completion now. It is difficult to test this. Fixes: Coverity CID 23037, CID 23038
2013-07-03gsm0408: Avoid unaligned memory access in gsm48_generate_mid_from_tmsiHolger Hans Peter Freyther3-2/+26
The &buf[3] is unlikely to be aligned properly. Use memcpy instead of an assignment. Add a small testcase that verifies that I didn't mess up the conversion. Alignment trap: osmo-nitb (3293) PC=0x492b7094 Instr=0xe5803003 Address=0xbeb259db FSR 0x801
2013-07-03strrb: Remove a tautology from the codeHolger Hans Peter Freyther1-1/+1
This already came up during review but now that Coverity complains about it as well, let us just remove it. The variable is unsigned so it can never be < 0. Fixes: Coverity CID 1040669.

2013-06-29BSSGP: prevent divide-by-zero in flow controlHarald Welte1-10/+33
If the BTS tells us to not send any data at all anymore (bucket leak rate of 0 bits per second), then we should respect this and not run into a divide-by-zero. However, as this indicates complete overload, we print a log message to that regard.

2013-06-19lapd: Upate the assert to OSMO_ASSERT and describe what we would like to haveHolger Hans Peter Freyther1-2/+2
Update the OSMO_ASSERT to what it should be like but can't due a known issue in the LAPDm code.
2013-06-19lapd: The two known LAPDm issues have been addressed, update the testHolger Hans Peter Freyther2-13/+7
The issue about the wrong padding has been found when creating the testcase in commit 15f740caa3a1ef681b3a5564daf6dfccb7b1e489 but the patch to fix that was never proposed by inclusion by its author. The issue about about the establish confirm carrying data with a wrong size is still present.
2013-06-18lapd_core: msgb_trim() the L2 padding from ESTABLISH.ind0.6.1Harald Welte1-2/+3
When a SABM(E) frame arrives, we have to trim the L2 padding (0x2b for gsm) before handing the data off to L3, just like we do with I frames. Also, we should use mggb_trim() or even msgb_l3trim() instead of manually fiddling with msgb->length and ->tail pointers.
