/* A hackish minimal BSC (+MSC +HLR) implementation */
VTY: decouple telnet_interface from 'struct gsmnet' We want the VTY and telnet code to be independent from the BSC application(s). As a side note, we also like to eliminate static global variables for 'struct gsm_network' all over the code. As such, telnet_init() is now passed along a "private" pointer, which getst stored in telnet_connection.priv. This telnet_connection is then stored in vty->priv, which in turn gets dereferenced if anyone needs a reference to 'struct gsm_network' from the BSC vty code. Also: * vty_init() now calls cmd_init() * the ugliness that telnet_init() calls back into the application by means of bsc_vty_init() function has been removed. * telnet_init() now returns any errors, so the main program can exit e.g. if the port is already in use.

Replace template-based SYSTEM INFORMATION with real implementation Before this commit, OpenBSC used templates for the SYSTEM INFO 1, 2, 3, 4, 5 and 6 messages. Those templates were patched in various places to reflect the network config like ARFCN. Now, we actually generate those SI messages ourselves, using values from the configuration file, and even calculating neighbor cell lists. All bts'es that you have configured in OpenBSC will end up in the neighbor cell list - which should be more than sufficient for the current small-single-site networks.

move to libcommon-cs: net init 2: move bsc_network_init decl to new .h bsc_network_init() is more fit to live in a BSC specific header, move it to new common_bsc.h. It will probably also absorb the BSC-specific part of gsm_network in the future. Adjust header includes across the board. Particularly, fix abis_nm.h by explicitly including gsm_data.h: it so far relied on other headers to do that, which now is no longer always given. Change-Id: I9edfb1e748bb1cb484fadd48b0406f5b3098e89b

Use libvlr in libmsc (large refactoring) Original libvlr code is by Harald Welte <laforge@gnumonks.org>, polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>. This is a long series of trial-and-error development collapsed in one patch. This may be split in smaller commits if reviewers prefer that. If we can keep it as one, we have saved ourselves the additional separation work. SMS: The SQL based lookup of SMS for attached subscribers no longer works since the SQL database no longer has the subscriber data. Replace with a round-robin on the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the subscriber is currently attached. If there are many SMS for not-attached subscribers in the SMS database, this will become inefficient: a DB hit returns a pending SMS, the RAM lookup will reveal that the subscriber is not attached, after which the DB is hit for the next SMS. It would become more efficient e.g. by having an MSISDN based hash list for the VLR subscribers and by marking non-attached SMS recipients in the SMS database so that they can be excluded with the SQL query already. There is a sanity limit to do at most 100 db hits per attempt to find a pending SMS. So if there are more than 100 stored SMS waiting for their recipients to actually attach to the MSC, it may take more than one SMS queue trigger to deliver SMS for subscribers that are actually attached. This is not very beautiful, but is merely intended to carry us over to a time when we have a proper separate SMSC entity. Introduce gsm_subscriber_connection ref-counting in libmsc. Remove/Disable VTY and CTRL commands to create subscribers, which is now a task of the OsmoHLR. Adjust the python tests accordingly. Remove VTY cmd subscriber-keep-in-ram. Use OSMO_GSUP_PORT = 4222 instead of 2222. See I4222e21686c823985be8ff1f16b1182be8ad6175. So far use the LAC from conn->bts, will be replaced by conn->lac in Id3705236350d5f69e447046b0a764bbabc3d493c. Related: OS#1592 OS#1974 Change-Id: I639544a6cdda77a3aafc4e3446a55393f60e4050

src: port openBSC over libosmo-abis This is a big patch that ports openBSC over libosmo-abis. Sorry, the changes that are included here are all dependent of libosmo-abis, splitting them into smaller pieces would leave the repository in some intermediate state, which is not desired. The main changes are: - The directory libabis/ has been removed as it now lives in libosmo-abis. - new configuration file format for nanoBTS and HSL femto, we need to define the virtual e1_line and attach it to the OML link. - all the existing BTS drivers (nanoBTS, hsl femto, Nokia site, BS11 and rbs2000) now use the new libosmo-abis framework. - use r232 input driver available in libosmo-abis for bs11_config. - use ipa_msg_recv instead of old ipaccess_read_msg function. - delete definition of gsm_e1_subslot and input_signal_data. These structures now lives in libosmo-abis. Most of this patch are deletions of libabis/ which has been moved to libosmo-abis. This patch also modifies openBSC to use all the new definitions available in libosmocore and libosmo-abis. In order to do that, we have replaced the following: - DINP, DMI, DMIB and DMUX by their respective DL* correspondences. - SS_GLOBAL by SS_L_GLOBAL - SS_INPUT by SS_L_INPUT - S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN - SS_INPUT by SS_L_INPUT - S_INP_* by S_L_INP_* sub-signals - E1INP_NODE by L_E1INP_NODE vty node This patch has been tested with: - one nanoBTS - the HSL femto with the examples available under libosmo-abis - BS11 with both dahdi and misdn drivers.

Improved generation of SYSTEM INFORMATIONs 2* and 5* for neighbour bands In addition to SI 2 and SI 5, the SI 2ter and 2bis is generated, if neighbour cells in other bands exist. Also it is indicated in the rest octets of SI3, that SI 2ter is used. If no neighbour cell in a different band exists, the SI 2ter and SI 5ter is omitted. A special case is P-GSM range (channels 1-124). To be compatible with older phones, SI 2bis and SI 5bis is used. If the BCCH lays inside the P-GSM band, only neighbour cells of the P-GSM range are included in SI 2 and SI 5. If neighbour cells exist in the same band (900), but lay outside the P-GSM range, the SI 2bis and SI 5bis is used to extend the list of neighbour cells. The extension is also indicated in SI 2 and SI 5. If the BCCH lays inside the P-GSM range, but no neighbour cell exists in the same band outside the P-GSM range, the SI 2bis ans SI 5bis are omitted.

Replace template-based SYSTEM INFORMATION with real implementation Before this commit, OpenBSC used templates for the SYSTEM INFO 1, 2, 3, 4, 5 and 6 messages. Those templates were patched in various places to reflect the network config like ARFCN. Now, we actually generate those SI messages ourselves, using values from the configuration file, and even calculating neighbor cell lists. All bts'es that you have configured in OpenBSC will end up in the neighbor cell list - which should be more than sufficient for the current small-single-site networks.

Fix TSC/BSIC handling bug and remove bts->tsc This fixes a bug in the following circumstances: * BSIC is set to 0 in the config file * No TSC is explicitly specified at the BST level in the config file In this case, we ended up using BSIC=0 and TSC=7, as TSC=7 is our default initialization value. The TSC of the CCCH/BCCH must always be the BCC, which is the lower 3 bits of the BSIC. Having configuration options for both the BSIC _and_ the TSC at the BTS level therefore makes no sense, as it only adds ways in which users can configure non-oprational configurations. So we remove the bts->tsc member, and keep only the ts->tsc members that allow us to configure a timeslot-specific TSC that's different from the BTS TSC (= BCC).

Sorry, the changes that are included here are all dependent of libosmo-abis, splitting them into smaller pieces would leave the repository in some intermediate state, which is not desired. The main changes are: - The directory libabis/ has been removed as it now lives in libosmo-abis. - new configuration file format for nanoBTS and HSL femto, we need to define the virtual e1_line and attach it to the OML link. - all the existing BTS drivers (nanoBTS, hsl femto, Nokia site, BS11 and rbs2000) now use the new libosmo-abis framework. - use r232 input driver available in libosmo-abis for bs11_config. - use ipa_msg_recv instead of old ipaccess_read_msg function. - delete definition of gsm_e1_subslot and input_signal_data. These structures now lives in libosmo-abis. Most of this patch are deletions of libabis/ which has been moved to libosmo-abis. This patch also modifies openBSC to use all the new definitions available in libosmocore and libosmo-abis. In order to do that, we have replaced the following: - DINP, DMI, DMIB and DMUX by their respective DL* correspondences. - SS_GLOBAL by SS_L_GLOBAL - SS_INPUT by SS_L_INPUT - S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN - SS_INPUT by SS_L_INPUT - S_INP_* by S_L_INP_* sub-signals - E1INP_NODE by L_E1INP_NODE vty node This patch has been tested with: - one nanoBTS - the HSL femto with the examples available under libosmo-abis - BS11 with both dahdi and misdn drivers.

abis_nm: Band aid on OML initialisation by queuing messages Instead of sending many messages we will queue the OML messages and wait for the ACK/NACK before sending the next message from the queue. We tag the msgb to remember if we need to wait for an ack or not. We keep the order of all messages, on ACKs and similiar occassions we will drown the queue until we reach a message that needs to be acked and then wait for that ack again. Possible breakage can appear when we send an OML (e.g. BS11 specific message) msg which does not need to be acked through the abis_nm_sendmsg call.

[BSC] Move the BTS-type specific code from bcs_init.c to bts_*.c bsc_init.c was a big mess even only for two supported BTS models, so before adding more BTS types, this needs a cleanup. All the BTS specific code from bsc_init.c has now moved into bts_{siemens_bs11,ipaccess_nanobts}.c This has required that input_event() and nm_state_event() get both converted to proper libosmocore signals instead of referencing external symbols.

bsc: on-demand setup of nanoBTS and HSL femto sockets The daemons set up nanoBTS and HSL femto sockets by default, ie. the three sockets to support these two drivers are open even if we have no BTS of that kind. This patch enables on-demand socket creation, ie. we only enable them if we have one BTS at least that requires it. I added two new attributes to the gsm_bts object, they are: * the start() function includes the code that we need to run to start the BTS. This new function contains the socket creation in the particular case of nanoBTS and HSL femto. * the started boolean, which is used to know if we have already started the BTS, ie. we have already invoked start(). Note that, I have splitted the bts_model_*_init() function into two functions, the _init() functions that register the BTS driver and the _start() functions that start BTS driver on-demand. While I was at it, I added several changes/cleanups to this patch: * Group all bts_model_*_init() calls into one function bts_init(), which is called in the initialization path of osmo-nitb and osmo-bsc. * Add openbsc/bss.h that contains the declaration of bsc_bootstrap_network, bsc_shutdown_net and bts_init. * Add missing e1inp_init() in osmo-bsc. * Fix missing declaration of hsl_setup in openbsc/e1_input.h

Replace template-based SYSTEM INFORMATION with real implementation Before this commit, OpenBSC used templates for the SYSTEM INFO 1, 2, 3, 4, 5 and 6 messages. Those templates were patched in various places to reflect the network config like ARFCN. Now, we actually generate those SI messages ourselves, using values from the configuration file, and even calculating neighbor cell lists. All bts'es that you have configured in OpenBSC will end up in the neighbor cell list - which should be more than sufficient for the current small-single-site networks.

enable telnet VTY bind address config for various programs Following the 'line vty'/'bind A.B.C.D' command added in libosmocore, use the configured address to set the telnet bind for the VTY line. It is now possible to publish the VTY on a specific local interface (including 0.0.0.0 aka "any"). Implement in all of: osmo-gbproxy osmo-gtphub osmo-sgsn osmo-bsc osmo-bsc_nat osmo-bsc_mgcp osmo-nitb In some of these main programs, move the telnet initialization below the configuration parsing. Historically, this was not a good idea for programs using bsc_init.c (aka bsc_bootstrap_network()), since they expected a gsm_network struct pointer in ((struct telnet_connection*)vty->priv)->priv, so that telnet had to be either initialized or replaced by a dummy struct. In the meantime, the gsm_network struct is not actually looked up in a priv pointer but in the static bsc_vty.c scope (bsc_gsmnet), so this limitation is mere legacy (even though said legacy is still there in an "#if 0" chunk). In the other binaries I have briefly looked at the init sequence dependencies and found no reason to initialize telnet above the config file parsing. In any case, I have tested every single one of abovementioned binaries to verify that they still parse the example config successfully and launch, allowing VTY connections on the configured address(es). I hope this suffices. In all of the above, log VTY address and port. LOGL_INFO is disabled by default in some of the logging scopes, and since it is a single log message right at program launch, I decided for the slightly more aggressive LOGL_NOTICE.

VTY: decouple telnet_interface from 'struct gsmnet' We want the VTY and telnet code to be independent from the BSC application(s). As a side note, we also like to eliminate static global variables for 'struct gsm_network' all over the code. As such, telnet_init() is now passed along a "private" pointer, which getst stored in telnet_connection.priv. This telnet_connection is then stored in vty->priv, which in turn gets dereferenced if anyone needs a reference to 'struct gsm_network' from the BSC vty code. Also: * vty_init() now calls cmd_init() * the ugliness that telnet_init() calls back into the application by means of bsc_vty_init() function has been removed. * telnet_init() now returns any errors, so the main program can exit e.g. if the port is already in use.

src: port openBSC over libosmo-abis This is a big patch that ports openBSC over libosmo-abis. Sorry, the changes that are included here are all dependent of libosmo-abis, splitting them into smaller pieces would leave the repository in some intermediate state, which is not desired. The main changes are: - The directory libabis/ has been removed as it now lives in libosmo-abis. - new configuration file format for nanoBTS and HSL femto, we need to define the virtual e1_line and attach it to the OML link. - all the existing BTS drivers (nanoBTS, hsl femto, Nokia site, BS11 and rbs2000) now use the new libosmo-abis framework. - use r232 input driver available in libosmo-abis for bs11_config. - use ipa_msg_recv instead of old ipaccess_read_msg function. - delete definition of gsm_e1_subslot and input_signal_data. These structures now lives in libosmo-abis. Most of this patch are deletions of libabis/ which has been moved to libosmo-abis. This patch also modifies openBSC to use all the new definitions available in libosmocore and libosmo-abis. In order to do that, we have replaced the following: - DINP, DMI, DMIB and DMUX by their respective DL* correspondences. - SS_GLOBAL by SS_L_GLOBAL - SS_INPUT by SS_L_INPUT - S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN - SS_INPUT by SS_L_INPUT - S_INP_* by S_L_INP_* sub-signals - E1INP_NODE by L_E1INP_NODE vty node This patch has been tested with: - one nanoBTS - the HSL femto with the examples available under libosmo-abis - BS11 with both dahdi and misdn drivers.

[HSL] initial support for the HSL 2.75G Femtocell The HSL Femtocell seems to be a poor man implementation of the ip.access Abis/IP protocol, but cutting corners wherever possible. We try to workaround those corners wherever possible...

bsc: fix bail out in case of problems bootstrapping BTS or E1 input The error message was missing in case of problems bootstrapping the BTS. The E1 input driver initialization was displayed in the standard output, now this error is reported via logs.
