Harald Welte f4d45ab021 gsm 08.08: use ANSI function definition with (void) 2011-07-16 12:13:00 +02:00
Harald Welte 79599ba0eb tlv: Make tlv parser arrays 256 entries wide to prevent overflow on 0xff 
If we encounter a tag with 0xFF, we overflow our existing tlv_parse
array definitions.

Harald Welte b43bc048eb logging: introduce library-internal logging categories 
We do this by using a trick: library-internal log categories use
negative subsystem numbers, which are converted into positive
array indexes at the time of logging.

library-internal log categories need to be knwo at compile-time,
while application-specified categories now are of unlimited number,
as they are dynamically allocated.

Harald Welte d58ba465f1 GSMTAP: add function to create a 'sink' for gsmtap packets 
This can be helpful where we send GSMTAP messages to the loopback
device (localhost, 127.0.0.1) from where the kernel would then
send ICMP reject packets as nobody is listening on that port.

Sylvain Munaut 19dc5c9cca core/conv: Add some generic code for convolutional coding/decoding 
Far from perfect but suits our need thus far.

The viterbi with softbit input is quite cpu-intensive. Since
most received bursts are often mostly error free, you could
use a less cpu intensive algorithm (Fano ?) and with hard bit
input. Then only switch to viterbi soft bit input if the channel
is bad enough to justify it.

Soft output is not implemented as its usefulness for the block
coding is limited.

Pablo Neira Ayuso 04139f14b6 vty: integration with logging framework 
The logging categories are registered by the applications, like
osmo-nitb, during startup. Thus, the VTY have to provide the logging
commands according to the logging categories that the application
has registered.

Before this patch, the VTY contained the logging categories
hardcoded. Thus, any change in the logging categories by the
application would not be shown by the VTY.

So far, this was not a problem because all applications used the
same logging categories. However, according to what Harald told
me, this may be a problem in the future.

This patch resolve the lack of integration between the logging
framework and the VTY by generating the VTY logging commands
from the logging categories registered.

Since this patch changes one function of the libosmocore API,
it follows another patch for the openbsc application to get in
sync with the new function layout.

I have reworked and renamed the functions:

 * log_vty_category_string()
 * log_vty_level_string()

to provide the new ones that generate the exact output that VTY
requires.

This patch does not release the memory allocated by
talloc_zero_size() to store the VTY strings for the commands
and the description. I found no exit function that can clean
up resources that were allocated.

A 'rate counter' is a counter that counts events but also keeps
track of the rate of events (per second, minute, hour and day).

'rate counters' are generally abstracted in 'rate counter groups',
which are instances of a 'rate counter group description'.  This
way we can have e.g. a description describing what kind of counters
a BTS (or TRX) has - and we can then create one instance of that
group for every BTS or TRX that exists.

Holger Hans Peter Freyther 8df932a7fd [write_queue] Add a generic write queue class 
The write queue can be a dropin replacement for the bsc_fd. It
is featuring two callbacks. One for ready read and one for ready
write. Whenever there is a message in the queue the write_queue
will set the BSC_FD_WRITE flag and then call the write callback.

It will make sure to delete the msgb after the write function
has been called. This class is intended to be be used in the
osmocom, layer2, bsc_msc_ip, bsc_hack and other applications.
