This allows us to pass in strings that are 'const', which for the

If a FSM doesn't specify any timer_cb, simply terminate the FSM by
default on time-out. This is a reasonable default for most cases, and
avoids copy+pasting a one-line timer_cb function in every FSM.
Also, even if there is a timer_cb, let it have a return value to decide
if the core should terminate after return from timer_cb or not.

Move those routines from OpenBSC to libosmogsm, so they can be
re-used from other programs. I think it was a mistake to add them only
inside the openbsc repository in the first place. We need to pay more
attention to this in the future.
To integrate with an external event loop (in this case glib) we
need to allow an application to get a filled out fd_set and then
dispatch it. osmo_fds and maxfds are static and I decided to keep
it that way and instead create two routines to fill the fdset and
then one to dispatch the result.
The public header file does not include sys/select.h and we can
compile the library without select, so I didn't want to require
having to include this file, and used void * for the parameter.
Mark the routines as inline to avoid a call from the select
function. I have confirmed that inlining has an effect on x86
using Debian's gcc-4.9.2-10 compiler
This function can be used to obtain the osmo_fd corresponding to a given
fd. The latter can be useful when integrating libosmocore main loop
with other libraries.
Add function which adds specified number of bits from each element of
array to the bit vector prefixing each addition with one and finishing
entire sequence with adding 0. This is very common patter for various
repetitive data structures described with CSN.1 in 3GPP standards.
Corresponding test vectors and doxygen headers are added too.
Currently the LOGP/DEBUGP arguments are always evaluated even if
no logging will happen at all. This can be expensive, for instance
if hexdumps or pretty printed object names are generated. This causes
high base load especially on embedded devices and is a major part of
CPU usage e.g. of the osmo-pcu.
This commit uses the log_check_level function to avoid the evaluation
of the parameters if it is known in advance, that no logging entry
will be generated.

This commit adds this predicate function which can be used to
avoid the execution of code if a certain log level is not enabled.
The function will only return 0 (false), if it is sure that a logging
call for the same facility and level will not produce any output.
This safety criterion shall ensure, that no logging output is lost
due to the use of this predicate as a guard. On the other hand, even
if the predicate returns != 0 (true), no logging output might get
generated by a similar logging command.
Note that the current implementation is not focussed on performance,
which could be improved by using a lookup table instead of iterating
through every target.

It's sometimes handy for debugging to be able to immediately see which
bits are set in a given byte. Generalize macro used for that in bitvec
tests and make it available for the rest of the library.
Add bit map encoder and decoder functions: decoder is fully functional
while encoder is good enough for testing - no backtracking to find
the best possible compression is implemented. If somebody is willing to
implement MS side of EDGE than this has to be expanded.

bitvec_read_field/bitvec_write_field in the PCU used a C++ reference

Shipping our own private copy of talloc was a good idea in 2008,

Currently only counter changes and new item values are being
reported. This makes it cumbersome to configure reporting clients,
since there is nothing like a list of all parameters.
This commit changes this behaviour such that all currently existing
counters and items that would be reported eventually, are passed to
the reporter when it has been reconfigured or enabled. If a counter
has not been incremented, 0 is sent. If a stat item value has not
been added, the last item value (or the default value if there is
none) is resent again.
Note that this will not catch transient counters/items that will be
created later on, e.g. triggered by new peers or subscribers.
To just force this kind of dump on a running reporter, it is
sufficient to invoke the 'enable' command in its configuration node.

Currently each stat item has a separate index value which basically
counts each single value added to the item and which can be used by
a reporter to get all new values that have not been reported yet.
The drawback is, that such an index must be stored for each stat
item.
This commit introduces a global index which is incremented for each
new stat item value. This index is then stored together with the item
value. So a single stored index per reporter is sufficient to make
sure that only new values are reported.

Currently it takes 3s to establish a SAPI 3 SACCH connection with
osmo-bts. This is due to the fact, that a broken SABME request is
sent first and and is ignored by the MS. Then, after a T200 timeout
(2s) the SABME command is sent again (this time correctly) and
answered by the MS.
The first SABME message is broken (it has a length field of 3 and
ends with 3 bytes from the tail of the original RSL message),
because of it is expected throughout lapdm.c that msg buffers
containing RSL have msg->l2h == msg->data. Some abis input drivers
fulfill this but IPA doesn't, thus the 3 bytes of the IPA header
are still part of the msg and confuse length computation.
Since internal fields of the msg are modified directly, this is
difficult to see.
This patch adds a new function msgb_pull_to_l3() that explicitely
skips over all headers prepending L3 and therefore resets l1h and
l2h. This function is then used instead of msgb_pull_l2h() which
only worked correctly when msg->l2h == msg->data. In addition,
code manipulating msg->tail and msg->len directly has been replaced
by calls to msgb_trim().
Note that this patch does not fix all issues of this case in the LADP
related code.

This function works like osmo_hexdump() and returns a static buffer
containing hex bytes along with markers for the layers.
Note that it uses osmo_hexdump() internally, thus a call to

earlier call to osmo_hexdump(). In short: don't mix them in a single

This reverts commit bf991bc0f3 and

test, since identifiers that aren't macros are just considered as

for GCC/Clang. The only difference was that for older compilers
the value of the definition was 0. Conditionally define these
macros.
Add a new core/defs.h file for definitions that can be used from
within header files without including prototypes and extern
declarations. It's primarily meant for macro definitions and basic
typedefs.
Move the definition of OSMO_DEPRECATED there and use compiler version
info to avoid compiler errors.
The modified macro is still working on a gcc 4.7 and gcc 4.8 after the
removal of the typedef and addition of the unused attribute.

This patch adds RB-tree based timers which scales better than the
previous list-based implementation.
It does not require any API changes. It breaks ABI because the
osmo_timer_list structure has changed though (to avoid this in
the future, we can put internal data in some private structure).
The following table summarizes the worst-case computational complexity
of this new implementation versus the previous one:
rb-tree list-based
------- ----------
calculate next timer to expire O(1) O(n)
insertion of new timer O(log n) O(n)
deletion of timer O(log n) O(1)
timer-fired scheduler O(log n) O(3n)
The most repeated cases are:
* the calculation of the next timer to expire, that happens in every
loop of our select function.
* the timer-fired scheduler execution.
This new implementation only loses in the deletion of timer scenario,
this happens because we may need to rebalance the tree after the
removal.
So I think there is some real gain if we have some situation in which
we have to handle lots of timers.
This patch adds red black trees implementation to libosmocore.
This data structure is very useful to search for elements in
ordered sets in O(log n) instead of O(n) that lists provide.
The first client of this code will be one follow up patch that
implements rbtree-based timer scheduler.

This patch adds a new attribute to msgb objects. This new
attribute will store a pointer to the routing information,

This deprecates msg->trx, that can be removed once all
application are ported to use msg->dst.
This adds the libosmo-abis logging subsystems to libosmocore,
it uses the new change that harald proposed based on negative
numbers for library logging subsystems.
The first range (from 0 to INT_MAX/2) of signal subsystems can be
used by client applications while the second range (from INT_MAX)
is reserved for libraries.
This is useful to support signals defined in libraries that
may be used by different client applications.
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.
This extends the socket infrastructure in libosmocore to allow
to create non-blocking sockets.
Basically, it replaces the connect0_bind1 parameter by one
flags parameter.
osmo_sock_init_ofd() is a wrapper around osmo_sock_init() which will
take care of initializing and registering a 'struct osmo_fd' for the
newly-created socket.
* use write_queue where applicable
* provide functions that work on raw FD and those with osmo_fd
* add support for multiple gsmtap instances (no global variables)
The plan is to collect structs and routines for application
setup and remove many copies of the boilerplate code we have
right now. This starts with routines to ignore certain signals
and the stderr init code.
Increment the age of the library because a new interface was added.

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

Soft output is not implemented as its usefulness for the block

This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.
This has been proposed by Harald Welte and Sylvain Munaunt.
Tested with `make distcheck'.
