* gsm: Add APN conversion functionsJacob Erlbeck2016-01-152-0/+77
| | | | | | | | | | | | These functions are currently part of openbsc but also needed by other projects. The function have been renamed as follows: gprs_apn_to_str -> osmo_apn_to_str gprs_str_to_apn -> osmo_apn_from_str Sponsored-by: On-Waves ehf

* LaPDm: Refuse SUSPEND/RESUME/RECONNECT in BTS modeHarald Welte2015-12-191-0/+17
| | | | | | The primitives for SUSPEND, RESUME and RECONNECT are only permitted on the MS side of the LAPDm link, not on the BTS side. So we should check for this and reject, accordingly.
* RSL: Add enum + TLV definitions for ip.access style embedded IEsHarald Welte2015-12-132-0/+27

* remove our internal copy of talloc, use system libtallocHarald Welte2015-12-051-2/+2
| | | | | | | Shipping our own private copy of talloc was a good idea in 2008, when it was not readily available on most target platforms. Today, the situation is quite different, as it is a standard library on major Linux distributions.

* build: have a disable-static build succeedJan Engelhardt2015-09-161-2/+6
| | | | | | | | | | | | | When using configure --disable-static, no libosmogsm.a will be created, and the tests fail to link because symbols like _a5_3 and _a5_4 are not exported through the only remaining libosmogsm.so. A method to overcome this is an intermediate private non-distributed library, examples of which are present in e.g. libabc, kmod and systemd. With this, disable-static can now be the default and practical compile time be halved.

| | | | | | | | | Addresses: CCLD utils/utils_test utils_test.o: In function `test_idtag_parsing': git/libosmocore/tests/utils/utils_test.c:64: undefined reference to `ipa_ccm_idtag_parse_off' Sponsored-by: On-Waves ehf
* ipa: Properly parse LV stream of a ID_GET requestHolger Hans Peter Freyther2015-06-021-3/+13
| | | | | | | | For some reason the structure is closer to be a LV (length and value). The value is actually a tag but it is counted inside the length. Introduce an overload of the parse function to provide an offset for the length. This will be taken from the returned length.
* Add APN utility function to libosmogsmHarald Welte2015-05-253-1/+42
| | | | | | The current functions are used to 'qualify' an APN from the user-supplied APN name (name identifier) towards the fully-qualified APN name which is used in the .grps DNS zone.
* msgb: Check the return value of msgb_alloc (Coverity)Jacob Erlbeck2015-04-101-0/+3
| | | | | | | | | | | In some places, the return value of msgb_alloc/msgb_alloc_headroom is not checked before it is dereferenced. This commit adds NULL checks to return with -ENOMEM from the calling functions if the alloc function has failed. Fixes: Coverity CID 1249692, 1293376 Sponsored-by: On-Waves ehf

* Supplementary Services (de)activation, interrogation addedTobias Engel2015-01-012-25/+102
| | | | | | | | | | | | | These patches enhance the Supplementary Service (SS) processing from only being able to handle USSD to other SS, specifically activation, deactivation and interrogation of those SS. Registration is not yet implemented. include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed values for SS. Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI stability.

* 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

* 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.

* 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.

* abis_nm: introduce abis_nm_{osmo,ipa}_magic[]Harald Welte2014-08-172-0/+5

* 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

* 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.
