Holger Hans Peter Freyther f8a342c350 gsm_7bit_decode: rtext does not hold a null byte, reduce the size 
I have added the + 1 as I thought rtext will hold a terminating
null byte but it will not.
 2010-07-21 03:14:01 +08:00
Nico Golde c0ce9aa20d tests: don't hardcode length values of expected encoding gsm_7bit_encode: 
make sure to return the number of actually written bytes gsm_7bit_decode:
calculate length of resulting septets from input length before decoding

The input length to gsm_7bit_decode reflects the number of encoded bytes
to be decoded. As the decoding is done on the input in septetes we need
to take this into account and recalculate the length.
 2010-07-21 02:43:58 +08:00
Holger Hans Peter Freyther 446bf37698 gsm_7bit_decode: Handle the case of the last charachter being an escape 
If i + 1 == length and it is an escape charachter we would try
to read rtext[length] which is one after the field we have allocated.
 2010-07-20 02:54:54 +08:00
Nico Golde 28de05336b * rewrite GSM 7bit default encoding/decoding based on a lookup table as the previous code produced wrong encodings for certain characters. 2010-07-20 02:48:17 +08:00

Andreas Eversberg 33f0fc3c95 [VTY] add support for numeric ranges with negative numbers

Harald Welte 6eb7d6c887 [RSL] split rsl_rll_push_l3() L3 LV pushign and rsl_rll_push_hdr() 
This allows us to generate RSLms messages that have some non-standard
IEs between the RSL/RLL common header and the L3 INFO IE.

Andreas Eversberg cd2a74bd43 Added single octet TV (type + value) to libosmocore. 
In case of a single octet, the upper nibble is the type, the lower nibble
carries the value.

Harald Welte d2dce6df04 [rate_ctr] always 'overflow' in next larger inetrval when interval ends 
If a second ends, we add the number of events in that just-ended second
to the number of events in the currently running minute.  The same happens
at the end of a minute: We add the number of events in that just-ended
minute into the number of events of the still-running hour, etc.

This gives a much more meaningful numbers and we don't end up with
"12 events per second, but 0 events per minute" kind of situations
anymore.

Harald Welte 7b45d60887 Add new 'rate counter' implementation to libosmocore 
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.

Right now I'm seeing crashes when removing a link and deleting

understand if llist_for_each_entry_safe has a bug or if we are
doing something bad with the list (anchors not properly initialized).

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.
