* ipa: Return -errno instead of -1 in ipa_sendJacob Erlbeck2014-12-221-1/+1
| | | | | | | | | | | | | Currently, the ipa_send function returns -1 in one execution branch to indicate an error and -EIO in another. This is not consistent and can lead to a misinterpretation of the error code, since -1 is -EPERM and in general, EPERM is not returned by write(2). This patch changes the return code to -errno instead of -1 for the case that write(2) fails for same reason. So -rc is always a sensible error value if there is a failure. Sponsored-by: On-Waves ehf
* fix libosmocore build for NuttX targetHarald Welte2014-12-041-0/+5
| | | | | | this fixes some compilation issues with libosmocore under NuttX, particularly as some #defines are missing or some header files are slightly different.
* Change copyright notice of ipa.c to GPLv2+Harald Welte2014-10-261-4/+4
| | | | ... which it should have been all along.
* Change license of gsm0411_smc/smr to GPLv2+Harald Welte2014-10-263-12/+12
| | | | | | libosmocore.{so,a} should always have been GPLv2+. However, when migrating some code from OpenBSC or OsmocomBB, we sometimes introduced it with a wrong license header.
* build: remove unused all_includes and use AM_CPPFLAGSJan Engelhardt2014-10-031-1/+2
| | | | | Preprocessor flags are best placed in AM_CPPFLAGS. Remove use of the unused all_includes variable, which is never set.
* misc: Look into the build directory for generated filesHolger Hans Peter Freyther2014-09-251-1/+1
| | | | | | 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.
* Fix copyright header in gan.cHarald Welte2014-09-111-4/+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.
* add missing copyright statements to source code filesHarald Welte2014-09-111-0/+19
| | | | | | 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.

* gsm0808: Fix copy and paste pointed out by clangHolger Hans Peter Freyther2014-08-211-1/+1
| | | | | | | | | | | | | | | The element following the identifier list was the GSM0808_IE_LSA_INFORMATION. It is a TLV type as well and the issue got introduced in 92107dfd3b99ab0dbb0f4770286454ad94a36de2. Fixes: gsm0808.c:316:40: warning: initializer overrides prior initialization of this subobject [-Winitializer-overrides] [GSM0808_IE_LSA_IDENTIFIER_LIST] = { TLV_TYPE_TLV }, ^~~~~~~~~~~~ gsm0808.c:315:40: note: previous initialization is here [GSM0808_IE_LSA_IDENTIFIER_LIST] = { TLV_TYPE_TLV },

* ipa: rename functions for consistencyHarald Welte2014-08-203-24/+39
| | | | | | | | As we are breaking builds by moving functions from libosmo-abis to libosmocore anyway, we might as well give functions more appropriate names. ipaccess is a company, while IPA is the multiplex protocol, and CCM is the protocol used for establishing identities on the IPA multiplex.
* import various generic IPA related functions from libosmo-abisHarald Welte2014-08-202-1/+448
| | | | | | | | | libosmo-abis is about forming A-bis interfaces/lines by means of E1 or the IPA multiplex (or possibly other link layers). The IPA multiplex is used in other contexts, such as the Control interface, or the A interface. In that context, it makes sense to have generic IPA related functions in libosmocore.

* update TS 08.08 header + TLV definitions to TS 48.008 / 11.7.0Harald Welte2014-06-211-16/+149
| | | | | | | | | | This adds support for A-over-IP and LCLS related message/IEI definitions. Old definitions are in decimal, which is very hard (at least for me) to compare with the binary tables in the spec. Hex is much easier to manually compare for completeness/correctness. I didn't touch the existing definitions, but think they should move to hex, too.

* gsm0411_smr: Fix the size of the arrayHolger Hans Peter Freyther2014-05-231-1/+1
| | | | | | | The code is lacking a "," at the end of a string and we ended up doing string concatination instead of having an invalid state. Fixes Coverity CID 1206564

* Fix introducing osmocom speficic OML attributesHarald Welte2014-05-192-0/+8
| | | | | | | | | | | | | | | | | | | Rename NM_ATT_O_REDUCEPOWER to NM_ATT_OSMO_REDUCEPOWER, which makes it more clear that this is an osmcoom specific attribute. Also, we cannot simply overload 0x01 as an already defined OML attribute. The problem is quite simple: When we use abis_nm_att_tlvdef during the TLV parse, 0x01 will match to NM_ATT_ABIS_CHANNEL, which is defined as { TLV_TYPE_FIXED, 3 }. So instead, we need to introduce a new abis_nm_osmo_att_tlvdef[], which has to be patched into abis_nm_att_tlvdef[] by the means of tlv_def_patch(), exactly how we do it for bs-11 and nanobts specific attributes. I'm using 0xfe for the attribute, as 0xfe doesn't overlap with the IPA specific attribues (and we might want to combine/merge the 12.21 plus IPA plus osmocom spefici attributes)

* gsm/lapdm: Prevent LAPD tx_queue from filling up in polling modeDaniel Willmann2014-03-262-0/+27
| | | | | | | If LAPDm receives an I-Frame while there already is an I-Frame in the tx_queue the code generates an additional RR (to acknowledge the received I-Frame). Instead, N(R) of the I-Frame in the tx_queue should be updated to ACK the data.
* lapdm: Make lapdm_datalink_for_sapi publicDaniel Willmann2014-03-262-3/+4
| | | | | This API allows you to get the lapdm_datalink for a SAPI. It's needed in the lapdm_test, so make it public.
* lapd: Improve log message and mention the SAPI the dl is onHolger Hans Peter Freyther2014-03-161-2/+2
| | | | | | | When debugging an issue that involves SAPI=0 and SAPI=3 the log file does not have enough context. Add the SAPI to this message so we at least understand which SAPI we are talking about.
* ladpm: Fix msgb handling and SAPI=3 establishment delayJacob Erlbeck2014-03-101-27/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it takes 3s to establish a SAPI 3 SACCH connection with osmo-bts. This is due to the fact, that a broken SABME request is sent first and and is ignored by the MS. Then, after a T200 timeout (2s) the SABME command is sent again (this time correctly) and answered by the MS. The first SABME message is broken (it has a length field of 3 and ends with 3 bytes from the tail of the original RSL message), because of it is expected throughout lapdm.c that msg buffers containing RSL have msg->l2h == msg->data. Some abis input drivers fulfill this but IPA doesn't, thus the 3 bytes of the IPA header are still part of the msg and confuse length computation. Since internal fields of the msg are modified directly, this is difficult to see. This patch adds a new function msgb_pull_to_l3() that explicitely skips over all headers prepending L3 and therefore resets l1h and l2h. This function is then used instead of msgb_pull_l2h() which only worked correctly when msg->l2h == msg->data. In addition, code manipulating msg->tail and msg->len directly has been replaced by calls to msgb_trim(). Note that this patch does not fix all issues of this case in the LADP related code.

* sms: Fix gsm_7bit legacy functions return valueJacob Erlbeck2014-01-091-6/+11
| | | | | | | | | | | | | | The legacy 7bit conversion functions (those without the '_n_' in the name) gave wrong return values on 64 bit platforms due to unproper signed/unsigned conversions and the usage of SIZE_MAX. This patch fixes this by using a smaller max size (see GSM_7BIT_LEGACY_MAX_BUFFER_SIZE, currently set to 64k) for the legacy wrappers and by using unsigned int for max_septets. In addition, there are tests now that check the return values of legacy encoding and decoding. Sponsored-by: On-Waves ehf

* gsm48: Added 'Network Daylight Saving Time' info elementJacob Erlbeck2013-09-161-0/+1
| | | | | | | | This information element has been added to the MM Information message in GSM24.008. This patch adds it to the tlv_definition to keep the TLV parser from breaking. Ticket: OW#978
* sms: Implement encoding the address as alphanumeric typeHolger Hans Peter Freyther2013-09-041-9/+21
| | | | | | The number of digits is the number of used octets times two (two digits per octet). The result has been successfully dissected by wireshark. It has not been tested with real phones.
* sms: Added comment about the gsm_7bit_alphabet tableJacob Erlbeck2013-08-121-2/+6
| | | | | The table structure is not intuitive, so this comment shall aid to understand this.
* sms: Added result buffer size parameter to 7bit conv funsJacob Erlbeck2013-08-123-59/+104
| | | | | | | | | | | | | The 7bit<->8bit encoding/decoding functions didn't check whether there is still enough space in the destination buffer. Therefore a buffer size parameter has been added to each of the functions which is used to truncate the output if the buffer is too small. In addition, the return value of the decoding functions has been changed to number of characters written (excluding \0), so this value is always equal to strlen(decoded). The old functions are still available as wrapper functions.
* lapd: Remove the double NULL check idiom with msgb_freeHolger Hans Peter Freyther2013-08-091-22/+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."

* Add special 7-bit encoding and decoding functions for USSD codingAndreas Eversberg2013-08-083-5/+38
| | | | | | | | | | | | | | | | | | | | | | | | 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>

* LAPD: Free resume/re-establishment msgb if it carries no contentAndreas Eversberg2013-07-101-2/+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.
