This marks the departure from printing all the debug messages to the console by
default. We only print NOTICE and WARNING level messages by default
If you're interested in more details, you need to enable it via command
line options or the VTY
The VTY code makes so many allocations that a full report is
simply too long to provide any useful information. So we sub-divide
it in multiple contexts, and report only one level deep at SIGURS1.
We also introduce SIGUSR2 for the full detailed VTY report.
In case we have multiple TRX configured, but not all of them are
actually active/operational, we should not try to allocate channels
from such transceivers.
This proxy allows us to restart OpenBSC while the BTS's are kept
running with their CCCH/BCCH alive. This is very useful to
make sure the phones don't roam to other networks while restarting
OpenBSC.
The proxy also intrduces UDP sockets for injecting UDP packets
into the A-bis data stream.
So far I have not much idea about the format. It is starting with
the magic byte and the header is spanning until the next occurence
of the " SDP" marker.
The magic " SDP" is occuring twice in the file. The first time
seems to be the file header and the second time it is with the
payload. We will need to parse this somehow...
* The two version strings are not in an easy to parse header
and from my trace it appears like the whole file is sent
to the BTS. So just open the firmware file..
Change the counters_store_db function to be a generic for_each
function taking a function pointer and data. Use that in bsc_hack
to store it to the DB.
This is removing the DB requirement and will allow to handle
the counter values in different ways without making the counter
list public.
I verified that the syncing is still taking place.
This is the new logging architecture, including
* support for multiuple logging targets like stderr and vty
* log levels in addition to categories/subsystems
* filtering based on imsi, i.e. only see events for one subscriber
* dynamically change log level for each category for each vty
This has the advantage that counters can be added all over the code
very easily, while having only one routine that stores all of the
current counter values to the database. The counters are synced
every 60 seconds, providing relatively fine grained statistics
about the network usage as time passes by.
Tweaking theses can be useful especially tx-integer that influence
both the spread of rach attemps and the delay between two attemps.
Looking up GSM 04.08 3.3.1.1.2 & 10.5.2.29 can help determine good
values. The default are choosed with a wide spacing between attemps
(tx integer = 9 -> T=12 & S=217 (non-combined CCCH/SDCCH) or 115 (for
combined CCCH/SDCCH)). This alleviates the problem of responding to
several RACH attempts by a same MS, allocating several RF channels when
only 1 is needed.
