* libosmocoding: migrate transcoding routines from OsmoBTSVadim Yanitskiy2017-03-078-0/+5555
| | | | | | | | | | | | | | | | | | | | | | | | | 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

* logging.h: fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*Neels Hofmeyr2017-02-237-43/+43
| | | | | | | | | | | | | | | 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. This and following commits are backwards compatible with those before that short window.

* logging: centrally define ctx and filter indexesNeels Hofmeyr2017-02-228-48/+49
| | | | | | | | | | | | | | | | | | | | | | | 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

* lapd_core: Fix MDL-ERROR ind after RELEASE indPhilipp Maier2017-02-071-4/+4
| | | | | | | | | in lapd_t200_cb() The RELEASE INDICATION is transmitted before the MDL ERROR INIDCATION, this prevents the MDL ERROR INDICATION from being sent because the RELASE INDICATION close to connection eraly. This commit puts the messages into the correct order. Change-Id: Iae74777138fc27828f511e3aa321d1981861f4a5
* lapd_core: fix program flowPhilipp Maier2017-02-071-5/+5
| | | | | | | | | | | | | | | | when the lapd core is in state LAPD_STATE_SABM_SENT, and the retransmission counter exceeds (link down) lapd_t200_cb() will send an RELASE_INDICATION and an MDL_ERROR_INDICATION to L3. 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.

* select: add functionality to check socket statePhilipp Maier2017-02-071-6/+24
| | | | | | | | | | | | osmo_fd_register() is used to register socket file descriptors, after registering a socket, there is no way to test if the socket is still registered or actually registered at all. This commit adds a new function osmo_fd_register_check() that can be used to check in advance, if the socket fd is registered, before performing further operations.

* osmo_auth*: fix ordering of function argsNeels Hofmeyr2017-02-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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

* GSUP, OAP, osmo-gen-vec: fix AUTS length to 14, not 16Neels Hofmeyr2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
