2017-01-23remove unneccessary linking from some testsNeels Hofmeyr3-4/+0
The recent shifts and cuts have made some library linking for bsc, channel and db tests unnecessary.
2017-01-23msc_release_connection(): don't call gsm0808_clear()Neels Hofmeyr1-1/+0
gsm0808_clear() is all about clearing lchans. To be able to link libmsc without libbsc, don't call it directly. Change-Id: I149146fc3cb99ef4a21ee2a798231bb070f398cd
2017-01-23cut off libbsc paging, pending paging in libmscNeels Hofmeyr5-2/+24
Temporarily disable all paging to be able to link libmsc without libbsc. Skip the paging part of channel_test because the paging is now disabled. In osmo-nitb, paging is done on BSC level and MSC level "at the same time". When the new CSCN is fully operational, paging will be controlled separately on the MSC level, and the BSC (RNC) level will be instructed over an IuCS or A-interface to negotiate paging with the MS (UE). This MSC level paging does not yet exist and will be added in subsequent commits. Change-Id: I8b6920ddc54fc3f2876a59664e6722666d8a8a4a
2017-01-23libmsc: duplicate gsm0808 / gsm48 functions (towards BSC)Neels Hofmeyr4-13/+68
In osmo-nitb, libmsc would directly call the functions on the BSC level, not always via the bsc_api. When separating libmsc from libbsc, some functions are missing from the linkage. Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also add a _tx to gsm0808_cipher_mode(): * add msc_gsm0808_tx_cipher_mode() (dummy/stub) * add msc_gsm48_tx_mm_serv_ack() * add msc_gsm48_tx_mm_serv_rej() Call these from libmsc instead of * gsm0808_cipher_mode() * gsm48_tx_mm_serv_ack() * gsm48_tx_mm_serv_rej() Also add a comment relatd to msc_gsm0808_tx_cipher_mode() in two places.

2017-01-23gsm_04_08, gsm_subscriber: decouple lac from btsNeels Hofmeyr3-11/+10
The idea is to not have a direct pointer to a bts struct (into BSC land), but a LAC to resolve the BSC or RNC depending on the appropriate A or IuCS interface. subscr_update(): remove bts arg, add lac arg. Pass conn->lac to gsm48_generate_lai() instead of bts->location_area_code. Change-Id: I9f2b298a785bf4b2a1b3fcdd91b8256106b2d9de

2017-01-23Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication.Neels Hofmeyr6-0/+149
Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to different interfaces depending on the actual subscriber connection. While iu_tx() is going to be functional fairly soon, the a_tx() is going to be just a dummy for some time (see comment). Add via_iface marker to gsm_subscriber_connection with enum values IFACE_A and IFACE_IU so far. Add Iu specific fields in a sub-struct: the UE connection pointer and an indicator for the Integrity Protection status on Iu (to be fully implemented in later commits). Add lac member to gsm_subscriber_connection, to allow decoupling from bts->location_area_code. The conn->lac will actually be set in iu.c in an upcoming commit ("add iucs.[hc]").

2017-01-23gsm_04_08.c: Don't set msg->lchan nor msg->dstHarald Welte1-34/+0
the BSC-side of the API behind gsm0808_submit_dtap() is doing this resolving again anyway. So let's avoid doing it twice, and avoid having more dependency of the MSC down into the lchan details. Conflicts: openbsc/src/libmsc/gsm_04_08.c Change-Id: I14254be68ee1a48e9f1ce968233414d86c6ba9d5

* Explicitly check when ARFCN array split is impossible and return gracefully instead of using negative index. * Separate range encoding into generic function and use it for all SI-related things. * Propagate the error into that function and to its callers. * Add separate test-case for the segfault previously triggered by this bug.

2017-01-15gprs subscr: fix: intended strcmp(), but is strcpy()Neels Hofmeyr1-5/+3
The code checked 'if (strcpy(..) != 0)' which is always true and thus always copied twice -- luckily we want to copy anyway and so this is not an actual functional failure. We could correct to strcmp, but instead of iterating to compare, we might as well copy right away. Change-Id: I0ea035bd478f7022ed65e9e84d8aaf5e423309b7

2017-01-13Revert "Turn some warnings into errors"Neels Hofmeyr2-9/+0
This introduces a failure with ./configure on my machine: ../configure: line 6612: syntax error near unexpected token `-Werror=implicit,' ../configure: line 6612: `AX_CHECK_COMPILE_FLAG(-Werror=implicit, CFLAGS="$CFLAGS -Werror=implicit")' Makefile:420: recipe for target 'config.status' failed make[1]: *** [config.status] Error 2 Installing autoconf-archive did not fix the error. So even though jenkins seems to accept this, I cannot build with this patch. Let's find out how to do this in a way that all systems can still build and then re-apply this patch. This reverts commit fd161ccce8ecaad3ddd32dd8b696902e81593ae3. Change-Id: I2b368500b07f233882ef854eca1fa21f6df39e29

2016-12-23sndcp: Allow empty SNDCP-XID indicationsPhilipp4-42/+61
In some rare cases the modem might send a xid indication that does not contain anything except the version number field. The sgsn ignors such SNDCP-XID indications by stripping the entire field from the response. We found a modem in the wild that started to act problematic when the empty SNDCP-XID was missing in the response. This patch changes the XID negotiation behaviour in a way that if a modem should send empty SNDCP-XID indications, the reply will also contain an empty SNDCP-XID indication. Apart from that the SNDCP-XID version number is now parsed and echoed in the response. This ensures that we always reply with the version number that the modem expects. (The version was 0 in all cases we observed so far) Change-Id: I097a770cb4907418f53e620a051ebb8cd110c5f2 Related: OS#1794
