* libosmocoding: migrate transcoding routines from OsmoBTSVadim Yanitskiy2017-03-0725-7/+8111
| | | | | | | | | | | | | | | | | | | | | | | | | There are some projects, such as GR-GSM and OsmocomBB, which would benefit from using one shared implementation of GSM 05.03 code. So, this commit introduces a new sub-library called libosmocoding, which (for now) provides GSM, GPRS and EDGE transcoding routines, migrated from OsmoBTS. The original GSM 05.03 code from OsmoBTS was relicensed under GPLv2-or-later with permission of copyright holders (Andreas Eversberg, Alexander Chemeris and Tom Tsou). The following data types are currently supported: - xCCH - PDTCH (CS 1-4 and MCS 1-9) - TCH/FR - TCH/HR - TCH/AFS - RCH/AHS - RACH - SCH Change-Id: I0c3256b87686d878e4e716d12393cad5924fdfa1

| | | | | | | | | | | | | | | My recent logging patch was merged to master a bit too soon. Accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING". libosmocore will not be backwards-compatible with the few commits from change-id I5c343630020f4b108099696fd96c2111614c8067 up to this one.

* logging.h: fix backwards compat broken by recent commitNeels Hofmeyr2017-02-231-0/+7
| | | | | | | | | | | | | | Commit 812ba6dc63a75c39678dd3fe652768e76bf63183 "logging: centrally define ctx and filter indexes" Removed definitions, which causes older e.g. openbsc and osmo-pcu code trees to fail to build against a newer libosmocore. Re-introduce the legacy definitions to redirect to the new ones and re-establish backwards compatibility. The GPRS_* constants used to be defined in gprs_msgb.h, but since that header also includes logging.h, rather place the legacy shims in logging.h next to the other ones.

* gsm_04_08.h: add R99 MSCR and CBQ3 to SI3 Ctrl Chan DescrNeels Hofmeyr2017-02-231-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | MSCR and CBQ3 are Release 1999 additions to the Control Channel Description IE of SI3. Assuming that no-one is using the spare bits, this will not cause any code conflicts. In the R99 struct, spare1 and spare2 are in different places, so rather rename them to spare_1 and spare_2 to make sure we get a compiler barf *if* anyone tries to use them with the wrong structure. Adjust the spec reference to TS 44.018; TS 04.08 Figure 10.5.33 is replaced by TS 44.018 Figure 10.5.2.11.1 which is right there in the named Section 10.5.2.11, so drop the explicit reference. Motivation: the R99 Control Channel Description defines MSCR to indicate whether the MSC is R99+ or not. To use UMTS AKA on GSM networks, we want to indicate that our libmsc is capable of R99, like OsmoSGSN already does. CBQ3 is merely added for completeness, no particular use case in mind.

* logging: centrally define ctx and filter indexesNeels Hofmeyr2017-02-2210-54/+66
| | | | | | | | | | | | | | | | | | | | | | | It is too easy for calling code to use the same filter and context indexes for different filters and structs. For example, openbsc's IMSI filter and libgb's GPRS_BVC filter both fall on index 1 even though there are plenty more indexes to choose from. To alleviate this, have one central definition here, sort of like ports.h does for VTY and CTRL port numbers. Add static asserts to make sure the indexes fit in the available array and bit mask space. Calling code like openbsc.git and osmo-pcu need adjustments and/or should move to using these enum values instead of their local definitions. Taking this opportunity to also prepare for a split of struct gsm_subscriber in openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter index constants for both subscriber types. Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its use by (1 << LOGGING_FILTER_ALL). Change-Id: I5c343630020f4b108099696fd96c2111614c8067

This action is done before the state is processed. This seems to be no problem with standard retransmission counts (n200), but may cause timing problems that lead to deadlock states when custom timer configurations are in use. (Ericsson RBS). This commit moves the functions calls for sending the indications mentioned above to the very end of the if branch to relax the timing again.

* osmo_auth*: fix ordering of function argsNeels Hofmeyr2017-02-062-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | milenage_gen_vec() has parameter ordering of (..., auts, rand_auts, rand). osmo_auth_gen_vec_auts() has (..., rand_auts, auts, rand), but actually feeds args in the same order, so that its rand_auts becomes auts, and its auts becomes rand_auts. Interestingly enough, API user osmo-gen-vec.c also adheres to this misordering and in turn passes auts for osmo_auth_gen_vec_auts()'s rand_auts and vice versa, so that it matches milenage_gen_vec(). So both the implementation (milenage_*) and the API user use the same ordering, just osmo_auth_gen_vec_auts() and osmo_auth_impl{ .gen_vec_auts() } in-between have the argument names swapped. Any current user of this API would need to adhere to this swapping or will not get successful AUTS resolution to a SQN. So the least impact fix is to rename the args without any actual functional change. So swap the names rand_auts and auts for osmo_auth_gen_vec_auts() and osmo_auth_impl{ .gen_vec_auts() }. (Also adjust API doc ordering) Change-Id: I0dcbd49759fc32d3b8974102dbd1d6703364ebf4

* osmo-auc-gen: cosmetic: clarify output upon AUTSNeels Hofmeyr2017-02-041-1/+14
| | | | | | | | | | | | | | | | | | | | | When calculating a re-sync vector using AUTS, osmo-gen-vec used to print SQN.MS + 2, the new SQN after vector generation, labeled 'SEQ.MS'. Firstly, s/SEQ/SQN. Secondly, print SQN.MS as umts.sqn - 2, which is the actual SQN recovered from the AUTS. As explained in the comment, SQN.MS + 1 is used to generate the vector, and then umts.sqn is increased a second time to indicate the next SQN. With AUTS calculated from SQN.MS == 23, the output was: AUTS success: SEQ.MS = 25 Output now: AUTS success: SQN.MS = 23, generated vector with SQN = 24, next SQN = 25 Change-Id: I881bbe8246a5e7d3a5065b4b5b533255723b1a9e

* GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr2017-02-027-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS to our osmo_auth_gen_vec_auts() API. According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14 bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2 and AUTS being the V = 14. It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But writing 16 bytes to a GSUP struct is a potential problem when passing in a 14 byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer. The API implies the length, so far to be 16, so passing in a 14 byte buffer to GSUP would require copying to a larger buffer first. Fix this by using a length of 14 for AUTS everywhere instead. This constitues an ABI breakage, we may handle it as a "fix before an official release", otherwise we need a version bump. The OAP protocol document has also been updated, needs an update in the osmo-gsm-manuals as well. Change-Id: If25b173d9ec57ea4c504d860954912b7d82af455
