[PATCH] Improved SAP interface integration
by Вадим Яницкий 04 Jan '16

04 Jan '16

This is final patch version. I did some tests and it seems works fine. One thing that I can't test is how SAP connection works because I have no working sap-server setup. If anyone have please test. Now the `sim sap MS_NAME` command just enables SAP connection and `sim remove MS_MANE` closes connection if it's active. What I have done: - Fixed GPSD configuration r/w errors; - Fixed sap_socket_path configuration r/w errors; - SAP interface starts only if it is configured as SIM source; - Now SAP interface is selectable as SIM source using the sim command in VTY. diff --git a/src/host/layer23/include/osmocom/bb/common/sap_interface.h b/src/host/layer23/include/osmocom/bb/common/sap_interface.h index bf19356..e4e64ce 100644 --- a/src/host/layer23/include/osmocom/bb/common/sap_interface.h +++ b/src/host/layer23/include/osmocom/bb/common/sap_interface.h @@ -11,6 +11,7 @@ int osmosap_sapsocket(struct osmocom_ms *ms, const char *path);

Happy New Year to all lists members! This patch fixes two bugs in mobile app: 1) If SAP connection fails mobile app does not save the sap-socket param in mobile.cfg. 2) The write command saves two unreadable strings: gpsd host HOST gpsd port PORT instead of: gpsd host HOST:PORT Patch source: diff --git a/src/host/layer23/include/osmocom/bb/common/sap_interface.h b/src/host/layer23/include/osmocom/bb/common/sap_interface.h index bf19356..e4e64ce 100644 --- a/src/host/layer23/include/osmocom/bb/common/sap_interface.h +++ b/src/host/layer23/include/osmocom/bb/common/sap_interface.h @@ -11,6 +11,7 @@ int osmosap_sapsocket(struct osmocom_ms *ms, const char *path); int osmosap_init(struct osmocom_ms *ms); enum osmosap_state { + SAP_SOCKET_ERROR, SAP_NOT_CONNECTED, SAP_IDLE, SAP_CONNECTION_UNDER_NEGOTIATION, diff --git a/src/host/layer23/src/common/sap_interface.c b/src/host/layer23/src/common/sap_interface.c index a56f4f2..33bfa6c 100644 --- a/src/host/layer23/src/common/sap_interface.c +++ b/src/host/layer23/src/common/sap_interface.c @@ -515,7 +515,8 @@ int sap_open(struct osmocom_ms *ms, const char *socket_path) rc = connect(ms->sap_wq.bfd.fd, (struct sockaddr *) &local, sizeof(local)); if (rc < 0) { fprintf(stderr, "Failed to connect to '%s'\n", local.sun_path); - set->sap_socket_path[0] = 0; + // set->sap_socket_path[0] = 0; + ms->sap_entity.sap_state == SAP_SOCKET_ERROR; close(ms->sap_wq.bfd.fd); return rc; } diff --git a/src/host/layer23/src/common/sim.c b/src/host/layer23/src/common/sim.c index 8e8d7bf..df9fbd2 100644 --- a/src/host/layer23/src/common/sim.c +++ b/src/host/layer23/src/common/sim.c @@ -188,7 +188,7 @@ static int sim_apdu_send(struct osmocom_ms *ms, uint8_t *data, uint16_t length) /* adding SAP client support * it makes more sense to do it here then in L1CTL */ - if(ms->settings.sap_socket_path[0] == 0) { + if(ms->sap_entity.sap_state == SAP_SOCKET_ERROR) { LOGP(DSIM, LOGL_INFO, "Using built-in SIM reader\n"); l1ctl_tx_sim_req(ms, data, length); } else { diff --git a/src/host/layer23/src/mobile/vty_interface.c b/src/host/layer23/src/mobile/vty_interface.c index 5782a17..9ac2221 100644 --- a/src/host/layer23/src/mobile/vty_interface.c +++ b/src/host/layer23/src/mobile/vty_interface.c @@ -1067,7 +1067,7 @@ DEFUN(cfg_no_gps_enable, cfg_no_gps_enable_cmd, "no gps enable", } #ifdef _HAVE_GPSD -DEFUN(cfg_gps_host, cfg_gps_host_cmd, "gps host HOST:PORT", +DEFUN(cfg_gps_host, cfg_gps_host_cmd, "gpsd host HOST:PORT", "GPS receiver\nSelect gpsd host and port\n" "IP and port (optional) of the host running gpsd") { @@ -1499,8 +1499,7 @@ static int config_write(struct vty *vty) struct osmocom_ms *ms; #ifdef _HAVE_GPSD - vty_out(vty, "gpsd host %s%s", g.gpsd_host, VTY_NEWLINE); - vty_out(vty, "gpsd port %s%s", g.gpsd_port, VTY_NEWLINE); + vty_out(vty, "gpsd host %s:%s%s", g.gpsd_host, g.gpsd_port, VTY_NEWLINE); #endif vty_out(vty, "gps device %s%s", g.device, VTY_NEWLINE); if (g.baud)

Why isn't there an airprobe for other protocols ? (3G, CDMA, LTE)
by John Case 13 Dec '15

13 Dec '15

I have successfully used airprobe (and gr-gsm, derived from airprobe) to see broadcast, unencrypted status messages from GSM base stations. It is my understanding that other protocols (like CDMA, UMTS, HSPA, LTE) have similar unencrypted, broadcast or "beacon" traffic that could be viewed the same way ... But there are no tools like airprobe for CDMA or 3G or LTE ... why is that ? Is there a technical reason that they are much more difficult, or has it just not been done yet out of lack of interest ? Thank you.

Re: Motorola C139 V1.9.24 Won't Load from osmocom-bb
by falcon＠ivan.Harhan.ORG 13 Dec '15

Hello fellow phone hackers, Back in March-April of 2014 there was a user on this list (Rusty Dekema, Cc'ed) who wanted to use OsmocomBB tools with a Mot C139 phone, but was stopped by a locked-down bootloader; the phone had Cingular firmware version 1.9.24 which none of us knew how to unlock back then. Fast-forwarding to the present, I recently got yet another batch of Mot C139 phones from ebay, and one of them came with that same fw version with a locked-down bootloader. This encounter prompted me to research the problem some more and develop a new shellcode injection- based method of breaking into these phones that should work with all existing Mot C1xx fw versions, gaining code execution on the phone's Calypso and allowing one to reflash the bootloader with an unlocked version, among arbitrary other reflashing and hacking operations. The new "universal" Mot C1xx unlocking tool is released as part of fc-host-tools-r4; the link to the tarball appears at the bottom of this web page: https://www.freecalypso.org/c139.html Happy hacking, Mychaela

What can I learn about a GSM base station without doing any decryption ?
by Mm Bsd 14 Oct '15

14 Oct '15

Hello, I am using a SDR device (a BladeRF) and there is a nice tool called 'kal' that will show me all of my nearby GSM base stations. In addition to listing base stations and their frequencies, I could also use that frequency info to monitor the beacon channel with gr-scan/airprobe. So at this point I know: - base station exists - I know its frequency - based on beacon channel assignments, etc., I *sort of* know how busy it is. But what else can be learned about a particular base station with simply passive observation and no decryption (and no sim card) ? If all I have is a passive monitor with a SDR, what else can I learn frmo the beacon channel or from the station itself ? Is it possible to learn things like software version, protocols supported, connectivity to network, or to other base stations ? My goal is to learn about the GSM networks around me and I wonder how deeply I can understand them with just passive observation of the beacon channel (or other sources of info that can be seen with SDR). Thank you.

Oct 15, 8pm / OSMUG: "Running OpenAirInterface"
by Harald Welte 09 Oct '15

09 Oct '15

Hi all! This is an announcement for an "irregular" Berlin Osmocom User Group event. David Rupprecht of Ruhr-Uni Bochum has offered to give us a presentation sharing his experience in Running OpenAirInterface. OpenAirInterface (http://openairinterface.eurecom.fr/) is a project of the Eurecom research institute in Sofia Antipoils / France. For many years they have been working towards an open source SDR LTE implementation. The presentation will be held on Oct 15, 8pm @ IN-Berlin, Lehrter Str. 53, 10557 Berlin (yes, this is _NOT_ CCC Berlin where regular OSMUG meetings are held!) The meeting is open to anyone interested in mobile communications. You do not have to be involved with the Osmocom projects in order to attend. Anyone interested in mobile communications protocols is welcome. If you are interested to show up, feel free to do so. The meeting is "free as in free beer", despite no actual free beer being around ;) More information about the venue can be found at http://www.in-berlin.de/space/ The official event announcement website is http://openbsc.osmocom.org/trac/blog/david-rub-openair-20151015 Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> ============================================================================ "Privacy in residential applications is a desirable marketing option."
