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

* Close the socket when the bind is failing.
* Close the socket when the listen is failing.
* Close the socket then the bsc_register_fd is failing.
* Return an error when the socket call is not returning a socket.

Make sending of the ID Request message public. We are going
to use this in the BSC NAT code to ask for querying the BSC.

If recv() has no more messages on a non-blocking socket, errno will be EAGAIN,
not the return value!

also: make sure we properly reset the OML/RSL UP flags on a dead socket.

we need to set newbfd->priv_nr to 2+trx_id, rather than keeping
it '2' all the time, as it is used to look-up the e1i_ts when
we receive a packet. A constant '2' would always match to TRX 0.
we also need to keep one separate bit for each TRX state in order
to properly generate the EVT_E1_TEI_UP event for trx > 0.

This is confirmed by looking at the source of their dissector.
The length can go up to 273 bytes apparently (again, according
to the source of their dissector).

and it appears to be right that for the "default" case ret
will not be assigned and we return ret.

Commit 9bd7bc1b4c4a3ba42da46931df650837c1a7e889 caused the RSL
initialization to happen too early, resulting in the BTS
bootstrapping but missing [some of?] the system information
types.

In order to support multi-TRX configurations, we need to be able
to cope with multiple RSL streams (each with their own stream identifier)
inside one ip.access TCP connection.
Since this is very similar to using the TEI on a E1 line, we simply
recycle the logic and data fields that are used for the TEI.

this fixes the delay of audio caused by stalling of the openbsc process.
the use of 'usleep(100000)' for slowing down transmission to nanoBTS is
replaced by the tx-delay timer. i did this on bs11 code, so i did it the
same way. it actually queues frames for transmission not nanoBTS. on
transmission a timer is started and when this timer expires, the next
frame in the queue is transmitted (timer restarted) until the queue is
empty.

This is a regression coming from the recent split of the
handle_ts1_read method in two.

For the MSC<->BSC connection we are going to use the same header
as used from BTS<->BSC but we are not having an E1-Link, a gsm network
or a gsm_bts available and can not use this part of the code.
|
|
The compiler thinks the variables might not be initialized, we
know it is wrong... but just make it happy.
|
|
We use the same construct in e1_inpit.c, use it here too.
|
|
|
|
return rc in these cases.

this was missing from commit a08a9acdb6bff0ee4fdf0f58b78b6525017a1f9f

In order to use multiple mISDN cards, we need to:
1) move driver initialization out of line initialization
2) make sure we allow partial (virtual) E1 cards with < 30 B-channels
|
|
This reportedly fixes the problem that we didn't see MEASurement REPort
messages from the BS-11.
|
|
when we generate a talloc report (SIGUSR1), we can now see which system
allocated a given msgb, this helps memory leak debugging
|
|
Prior to this patch, nanobts was not able to operate after recent changes
|
|
This makes it much easier to do run-time configuration using the vty
interface.
