libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

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.
The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.
Currently the nanoBTS bootstrap code requires a high delay
otherwise we are not bringing the device up properly. Changing
the init code turns out harder than it seems like. So this is
a workaround for that to allow a high speed RSL/OML connection
after the bringup.
The line driver can have a default TS delay. It is set to the
current default for the nanoBTS and the BS11. For the ipaccess
case we will set the delay lower for the RSL connection and
inside the ipaccess-config we can set it low right away to
have fast firmware flashing and such.
... while asking the BTS to perform tests for us. The length of the
ARFCN whitelist is the actual length in bytes, not the number of 16bit
ARFCN numbers.
Also, implement a limit, either by rxlevel or by number of ARFCN
that should end up in the whitelist.
Also, we now re-start the network listen test after it has finished,
so if you run a test from ipaccess-find, the test will get re-started
and re-started all the time.
there are now human-readable names so you can do something like
ipaccess-config -U dhcp-enabled -S static-ip -S static-gw 192.168.100.120
to unset DHCP and to set static IP and gateway attributes.
This looks so much better than the *cur++ type code.
Also, we now terminate ipaccess-config once the NV flags or Unit ID have
been set, not just for the OML IP address.
For the multi TRX setup we will need to specify the right trx->nr
to be able to flash the BTS. For the BS11 case we are ignoring the
additional argument.
Send the IPA Restart to a given BTS/TRX, change the signal callbacks
to carry the trx instead of the BTS so we have an easy access to the
right TRX and change the ipaccess-config to use that TRX. This is
fixing the restart with a multi TRX setup.
Even if we have the msg->trx, use the gsm_bts_trx_by_nr and get
the TRX from the fom header. This is because the OpenBSC and the
BTS numbering might not match for the multi TRX case.
Currently we are connecting to the BTS and once the OML is established
we are bootstrapping the OML. This does not work for a multi TRX setup
as we will need to use a trx_nr != 0 for it.
Change the code to wait for a message (in this case NM OC_BASEBAND_TRANSC)
to detect the trx_nr used by the BTS and then use that TRX to bootstrap
the network.
I have tested setting the unit id on a single and multi trx system for
the first and second trx.
The logging/debugging code is generic enough to move it into libosmocore
while keeping OpenBSC specific definitions in openbsc itself.
This commit uses the logging support present in libosmocore-0.1.2,
you will have to update your library to this version.
Currently one has to put -w in front of -f to really write the
firmware file to disk. Change the config handling to first take
all parameters and then execute on them. This means -f can now
be used with any other parameter.
Use the start address inside the header entry, the start is relative
to the surrounding SDP record which is located in our base offset, when
writing it out also ignore four bytes of something (crc?).
This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC
* Do not issue the restart right aways if we have OML IP or
software load in the queue (hint, we need a real queue of operations
to carry out... with one big state machine)
* Change the signal_data of ipacc ACK/NACK to contain the msg type
and the bts pointer.
* Issue a restart for software load and OML and use the BTS pointer
we got out of the new signal data.
We are filling sw_load1 with the information found with type
0x1000 and sw_load2 with type 0x2001. It appears from the protocol
traces that these information is not extracted from them. We also
need to include the \0 from the string.
With this firmware flashing seems to work.
