2016-06-16dyn PDCH: TS flags: rename one, add three, as enumNeels Hofmeyr1-1/+8
Rename TS_F_PDCH_MODE to TS_F_PDCH_ACTIVE, to more accurately reflect the truth value's meaning. Add TS_F_PDCH_ACT_PENDING and TS_F_PDCH_DEACT_PENDING for sysmoBTS (and possibly other BTS implementations) to remember what to do when the PCU replies with a channel de/activation. Also add TS_F_PDCH_PENDING_MASK to test for both. Change from #define to an enum. Note: These flags are also used in the upcoming osmo-bts-sysmo dyn PDCH commits, so osmo-bts submission depends on this commit. Change-Id: I391a103ab599648b0c5d4f3ad613a6d7c48834b3
2016-06-14Make random extension range configurableMax3-3/+8

2016-06-14dyn PDCH: send PDCH ACT for each TCH/F_PDCH on TS EnableNeels Hofmeyr1-0/+2
Add dyn_pdch_init() in new file bsc_dyn_pdch.c (new file to avoid linking issues; bsc_init.c would create undefined references, and putting in a new file is the easiest solution). Call dyn_pdch_init() from nm_statechg_event() whenever a TS is enabled. Revert the |= TS_F_PDCH_MODE chunk from previous commit, since this flag will now be set after dyn_pdch_init() sent out the PDCH ACT and when subsequently the PDCH ACT ACK messages are received in rsl_rx_pdch_act_ack().

2016-06-10DTX: add data necessary for schedulingMax1-0/+5
DTXd: to schedule SID repetition we have to know when previous SID was sent (fn) and if it was UPDATE or FIRST SID (is_update). DTXu: to properly set Marker bit in outgoing RTP we have to know the beginning of talkspurt. For codecs without explicit ONSET event we can do it by setting the flag (ul_sid) upon receiving SID and unsetting it on speech frames.

2016-06-05Add regexp authorization policy for IMSIMax1-0/+6
* extend "auth policy" vty command with new option "regexp" * add vty command "authorized-regexp" for setting arbitrary POSIX regular expression * add basic vty test * add optional "regexp" argument to subscriber-create-on-demand vty command With those in place we can now set the regexp against which MS's IMSI will be matched. If IMSI match the regexp than MS is allowed to access the network. If subscriber is already marked as authorized in HLR than it'll be allowed regardless of IMSI matching. The same way we can decide whether to create subscribers on-demand basesd on IMSI regexp match. Similar to authorization this restriction can be overridden by manually creating subscriber via vty, ctrl interface or directly in HLR.

In GSM R99 SI6 has mandatory SI6 rest octets and so far we did not include them. Add minimal support to generate the right band indicator. Target a slightly older version of the SI6 rest octets as we neither support MBMS nor Random bit stream but should include the band indicator.

2016-04-29osmo_oap_decode(): Use common argument orderingHarald Welte1-2/+2
In general, if a function generates output data like a msgb (or in this case filling an osmo_oap_message structure), the output argument precedes the source. This is what we use all over libosmo*, and it is modelled after memcpy(), where dst is the first argument, before src. Let's align osmo_oap_decode(). Intestingly, osmo_oap_encode was already correct, so the encode/decode functions used different conventions before.

2016-04-29Start to use struct osmo_auth_vector from gsm_auth_tupleHarald Welte2-5/+4
Rather than having a 'private' structure for kc, sres and rand, we now finally (with 4 years delay) use osmo_auth_vector from libosmogsm, which encapsulates authentication vectors that can be either GSM triplets or UMTS quintuples or a combination of both. gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding use_count and key_seq to it. key_seq is no longer initialized inside gprs_gsup_messages.c, as there is no CKSN / key_seq inside the message anyway. If a usre of the code needs key_seq, they need to manage it themselves.

2016-03-31MM Auth: introduce AUTH_ERROR constant.Neels Hofmeyr1-0/+1

2016-02-25smpp: refactor initialization, add bind addressNeels Hofmeyr1-2/+2
Make the SMPP bind address configurable (used to be harcoded as "0.0.0.0"). Add VTY command smpp local-tcp A.B.C.D <1-65535> while keeping the old command 'local-tcp-port <1-65535>'. Both the old and the new command immediately change the SMPP listening address and port. Add a LOGL_NOTICE log when the SMPP listening address and/or port change. However, to be useful, this patch has to go somewhat further: refactor the initialization procedure, because it was impossible to run the VTY commands without an already established connection. The SMPP initialization procedure was weird. It would first open a connection on the default port, and a subsequent VTY port reconfiguration while reading the config file would try to re-establish a connection on a different port. If that failed, smpp would switch back to the default port instead of failing the program launch as the user would expect. If anything else ran on port 2775, SMPP would thus refuse to launch despite the config file having a different port: the first bind would always happen on 0.0.0.0:2775. Change that. In the VTY commands, merely store address and port if no fd is established yet. Introduce several SMPP initialization stages: * allocate struct and initialize pointers, * then read config file without immediately starting to listen, * and once the main program is ready, start listening. After that, the VTY command behaves as before: try to re-establish the old connection if the newly supplied address and port don't work out. I'm not actually sure why this switch-back behavior is needed, but fair enough. In detail, replace the function smpp_smsc_init() with the various steps smpp_smsc_alloc_init() -- prepare struct for VTY commands smpp_smsc_conf() -- set addr an port only, for reading the config file smpp_smsc_start() -- establish a first connection, for main() smpp_smsc_restart() -- switch running connection, for telnet VTY smpp_smsc_stop() -- tear down connection, used by _start() twice And replace smpp_openbsc_init() smpp_openbsc_set_net() with smpp_openbsc_alloc_init() smpp_openbsc_start() I'd have picked function names like "_bind"/"_unbind", but in the SMPP protocol there is also a bind/unbind process, so instead I chose the names "_start", "_restart" and "_stop". The smsc struct used to be talloc'd outside of smpp_smsc_init(). Since the smsc code internally uses talloc anyway and employs the smsc struct as talloc context, I decided to enforce talloc allocation within smpp_smsc_alloc_init(). Be stricter about osmo_signal_register_handler() return codes.

The old -m option without argument is still available and marked deprecated, to not make users' lives more difficult than necessary.
2016-02-22sgsn: Re-add searching for MM ctx based on TLLI / P-TMSI matchesJacob Erlbeck1-0/+4
If an MM context cannot be found based on BBSGP info and a RA UPDATE REQUEST is received, try to find an MM context with an P-TMSI from which the TLLI could have been derived. This also checks, whether the routing area matches. This is similar to the old behaviour removed by the commits "sgsn: Only look at TLLIs in sgsn_mm_ctx_by_tlli" and "sgsn: Remove tlli_foreign2local", except that this will only be done for RA UPDATE REQUESTs now.
