[PATCH] Added new auth policy black-list.

by Ivan Kluchnikov

In this mode by default we set authorized = 1 for all new subscribers. BSC accepts all MS, except subscribers not authorized in DB. All subscribers with authorized = 0 are part of the black list and not accepted. --- openbsc/include/openbsc/gsm_data.h | 1 + openbsc/src/libbsc/bsc_vty.c | 5 +++-- openbsc/src/libcommon/gsm_data.c | 1 + openbsc/src/libmsc/db.c | 12 +++++++++--- openbsc/src/libmsc/gsm_04_08.c | 2 ++ 5 files changed, 16 insertions(+), 5 deletions(-) diff --git a/openbsc/include/openbsc/gsm_data.h b/openbsc/include/openbsc/gsm_data.h index 8741505..99e9b27 100644 --- a/openbsc/include/openbsc/gsm_data.h +++ b/openbsc/include/openbsc/gsm_data.h @@ -194,6 +194,7 @@ enum gsm_auth_policy { GSM_AUTH_POLICY_CLOSED, /* only subscribers authorized in DB */ GSM_AUTH_POLICY_ACCEPT_ALL, /* accept everyone, even if not authorized in DB */ GSM_AUTH_POLICY_TOKEN, /* accept first, send token per sms, then revoke authorization */ + GSM_AUTH_POLICY_BLACK_LIST /* accept everyone, except subscribers not authorized in DB */ }; #define GSM_T3101_DEFAULT 10 diff --git a/openbsc/src/libbsc/bsc_vty.c b/openbsc/src/libbsc/bsc_vty.c index 5748945..7a89ca6 100644 --- a/openbsc/src/libbsc/bsc_vty.c +++ b/openbsc/src/libbsc/bsc_vty.c @@ -1186,12 +1186,13 @@ DEFUN(cfg_net_name_long, DEFUN(cfg_net_auth_policy, cfg_net_auth_policy_cmd, - "auth policy (closed|accept-all|token)", + "auth policy (closed|accept-all|token|black-list)", "Authentication (not cryptographic)\n" "Set the GSM network authentication policy\n" "Require the MS to be activated in HLR\n" "Accept all MS, whether in HLR or not\n" - "Use SMS-token based authentication\n") + "Use SMS-token based authentication\n" + "Accept all MS, except not authorized in HLR\n") { enum gsm_auth_policy policy = gsm_auth_policy_parse(argv[0]); struct gsm_network *gsmnet = gsmnet_from_vty(vty); diff --git a/openbsc/src/libcommon/gsm_data.c b/openbsc/src/libcommon/gsm_data.c index 5f7e32e..31b65ee 100644 --- a/openbsc/src/libcommon/gsm_data.c +++ b/openbsc/src/libcommon/gsm_data.c @@ -256,6 +256,7 @@ static const struct value_string auth_policy_names[] = { { GSM_AUTH_POLICY_CLOSED, "closed" }, { GSM_AUTH_POLICY_ACCEPT_ALL, "accept-all" }, { GSM_AUTH_POLICY_TOKEN, "token" }, + { GSM_AUTH_POLICY_BLACK_LIST, "black-list"}, { 0, NULL } }; diff --git a/openbsc/src/libmsc/db.c b/openbsc/src/libmsc/db.c index 21abce9..440509a 100644 --- a/openbsc/src/libmsc/db.c +++ b/openbsc/src/libmsc/db.c @@ -319,6 +319,7 @@ struct gsm_subscriber *db_create_subscriber(struct gsm_network *net, char *imsi) { dbi_result result; struct gsm_subscriber *subscr; + int authorized = 0; /* Is this subscriber known in the db? */ subscr = db_get_subscriber(net, GSM_SUBSCRIBER_IMSI, imsi); @@ -337,17 +338,22 @@ struct gsm_subscriber *db_create_subscriber(struct gsm_network *net, char *imsi) if (!subscr) return NULL; subscr->flags |= GSM_SUBSCRIBER_FIRST_CONTACT; + + if (net->auth_policy == GSM_AUTH_POLICY_BLACK_LIST) + authorized = 1; + result = dbi_conn_queryf(conn, "INSERT INTO Subscriber " - "(imsi, created, updated) " + "(imsi, created, updated, authorized) " "VALUES " - "(%s, datetime('now'), datetime('now')) ", - imsi + "(%s, datetime('now'), datetime('now'), %d) ", + imsi, authorized ); if (!result) LOGP(DDB, LOGL_ERROR, "Failed to create Subscriber by IMSI.\n"); subscr->net = net; subscr->id = dbi_conn_sequence_last(conn, NULL); + subscr->authorized = authorized; strncpy(subscr->imsi, imsi, GSM_IMSI_LENGTH-1); dbi_result_free(result); LOGP(DDB, LOGL_INFO, "New Subscriber: ID %llu, IMSI %s\n", subscr->id, subscr->imsi); diff --git a/openbsc/src/libmsc/gsm_04_08.c b/openbsc/src/libmsc/gsm_04_08.c index d81dab9..8f8eaa9 100644 --- a/openbsc/src/libmsc/gsm_04_08.c +++ b/openbsc/src/libmsc/gsm_04_08.c @@ -241,6 +241,8 @@ static int authorize_subscriber(struct gsm_loc_updating_operation *loc, return (subscriber->flags & GSM_SUBSCRIBER_FIRST_CONTACT); case GSM_AUTH_POLICY_ACCEPT_ALL: return 1; + case GSM_AUTH_POLICY_BLACK_LIST: + return subscriber->authorized; default: return 0; } -- 1.7.9.5 -- Regards, Ivan Kluchnikov. http://fairwaves.ru

[PATCH 1/4] ussd: Send USSD on call setup on MSC errors

by Jacob Erlbeck

Send an USSD message to the mobile station requesting a connection for a call or a SMS when the link to the MSC is down or in the grace period. The messages can be set (and this feature activated) by setting bsc/missing-msc-text resp. msc/bsc-grace-text via the vty. The generation of both messages has been tested manually.

OpenBSC with A-interface

by Dmitri Soloviev

Hi list, Peter, thank you for your reply. I still have questions about media control: 1) when parsing MGCP CRCX, sdp is not expected. May I change it? 2) I still can't run media in BSC mode. Seems I'm missing something. osmo-bsc and osmo-bsc_mgcp are running BSSAP works perfectly But it seems two interfaces are working completely independent: -- MGCP between MSC and BSC -- interface between BSC and BTS (ip.access): at MGCP, connection is acknowledged, endpoint is allocated (at BSC ip=192.168.1.11) at ip.access interface between BSC and BTS, BTS replies to ip.accessCRCX with proper acknowledgement with proper ip:port at BTS (192.168.1.9) , then BSC issues ip.accessMDCX with endpoint ip zero: 7e:73:01:09:f8:00:2d:*f0:00:00:00:00*:f1:0f:be:f4:00:f2:03 My attempts to modify connection at MGCP interface has no impact on ip.access interface The key question, I'm not getting how osmo-bsc and osmo0bsc_mgcp are interacting.

l1-sap patches for osmo-bts

by Andreas Eversberg

hi, i reworked my l1sap patches for osmo-bts. (they are the base for adding osmo-bts-trx model code, which allow support for OpenBTS transceivers, like UmTRX or Calypso-BTS.) each single patch was tested, if Sysmocom-BTS is still functioning after applying it, rather than testing all patches together. i do not send the patches to mailing list, since there are 21 patches, and i don't want to spam the list before i know that these patches are small enough to be reviewed and understood. the branch is jolly/l1sap_parts. please let me know, whether they require better description or finer splitting. regards, andreas from last path to first patch: commit 0c0229886f6f6eba029c044e4cac8b420d86cd1c Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 12:30:52 2013 +0200 Remove obsolete gsmtap handling from osmo-bts-sysmo part. commit dfc8a3635e527960fa615c4ce7342e9739230a79 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Jun 16 15:09:56 2013 +0200 sysmobts: Forward CMR from L1 (Phone) to RTP payload commit 8cfffc712914107fe8277c96ad3afb1891f25014 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 12:06:19 2013 +0200 Add gsmtap option to command line to main.c of osmo-bts-sysmo commit 8ca47efb9cf9861a2766c41b96469263e1e13ed9 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 12:04:49 2013 +0200 Move gsmtap VTY commands from osmo-bts-sysmo to common part commit 2653aee1604d1504d707c9ed264dcb5cdaf2b01d Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Mon Jul 29 09:45:22 2013 +0200 Send primitives at PH-/MPH-/TCH-SAP interface via GSMTAP commit 66c08e87a2985ffd48e6d870ac6318c2b82a1476 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 11:57:07 2013 +0200 Move loopback control VTY commands from osmo-bts-sysmo to common part commit 8015bfcb3014c707bfe16ed4b52612e6fe377e75 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Thu Feb 14 11:17:58 2013 +0100 Correctly fill system information messages from BSC SI 5*/6 require L2 header of 0x03,0x03.

LCHAN_CIPH_RX_CONF -> LCHAN_CIPH_RX_CONF_TX_REQ -> LCHAN_CIPH_RXTX_CONF It is used to additionally enable ciphering in TX (downlink) direction. 3. LCHAN_CIPH_NONE -> LCHAN_CIPH_RXTX_REQ -> LCHAN_CIPH_RX_CONF_TX_REQ -> LCHAN_CIPH_RXTX_CONF It is used to enable ciphering in both TX and RX directions. This is used when the channel is activated with encryption already enabled. (assignment or handover) In order to follow the order of these transitions, the RX direction must always be set before the TX direction. If no cipher key is set (A5/0), ciphering is set to ALG 0, but lchan cipher state remains at LCHAN_CIPH_NONE. commit c5f478d8d6702961dfb74642108187e653a05775 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sat Aug 31 20:30:40 2013 +0200 Add MEAS (MPH_INFO) IND message to PH-/MPH-/TCH-SAP interface This part moves processing of measurement infos from osmo-bts-sysmo to common part. commit ffc1cc39ea28b695b98eedd1d16bdd023e4a77ad Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Sep 1 11:09:20 2013 +0200 Add SDCCH/SACCH/FACCH messages to PH-/MPH-/TCH-SAP interface This part moves control channel message primitives from osmo-bts-sysmo to common part.

[PATCH 1/6] vty: Fix BSC_NODE prompt string

by Jacob Erlbeck

Change '%s(bsc)#' to '%s(config-bsc)# '. The missing trailing blank brakes osmopy's VTYInteract.command() because the blank is contained in the end patterns which are checked to decide whether to leave the select loop. Thus trying to execute the 'bsc' command there blocks the test script forever. --- openbsc/src/osmo-bsc/osmo_bsc_vty.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/openbsc/src/osmo-bsc/osmo_bsc_vty.c b/openbsc/src/osmo-bsc/osmo_bsc_vty.c index 8eaa55b..f6cf1a0 100644 --- a/openbsc/src/osmo-bsc/osmo_bsc_vty.c +++ b/openbsc/src/osmo-bsc/osmo_bsc_vty.c @@ -43,7 +43,7 @@ static struct osmo_msc_data *osmo_msc_data(struct vty *vty) static struct cmd_node bsc_node = { BSC_NODE, - "%s(bsc)#", + "%s(config-bsc)# ", 1, }; -- 1.7.9.5
