Harald Welte c0f0007292 import oap message parsing / encoding from openbsc.git; AGPL->GPL
In the process, also:
* Change the license from AGPLv3 to GPLv2-or-later;
* correct spelling of 'sysmocom' to lowercase;
* add '2016' to the copyright;
* rename to osmo_*;
* add API docs;
* add logging category DLOAP: define id and add to internal_cat;
* redirect all oap.c logging to DLOAP.

A unit test will follow in a subsequent patch, since it needs a minor tweak for
decoding of boolean values.

Neels Hofmeyr 9795cf1b12 fix: DLGSUP logging category "unusable"
All DL* categories are typically negative, but DLGSUP isn't, and it's also not
in libosmocore's internal_cat array.
See: 3b6fb0880c

This means that a program using DLGSUP has to include DLGSUP in its own logging
cat array (typically not needed for DL* categories), which means for osmo-nitb
that DLGSUP (11) replaces DMGCP (also 11), and DMGCP becomes unusable.

Fix this: make DLGSUP -11 and include in internal_cat.

In gsup_test.c, no longer add DLGSUP to the logging categories array.

External follow-ups are otherwise needed only in osmo-hlr.git and some pending
patches for openbsc (Id3938267fa062e1a997d3704cd678874306f86ee).

Holger Hans Peter Freyther c7f52c4c84 wqueue: Reject messges if queue is considered full
The write queue was always meant to not queue more than the
max_length messages but the implementation never rejected a
message.

Begin to log and enforce the queue size limit, add a testcase
to verify the code and initialize except_cb as part of a fix
for that new test case.

Real applications might now run into the queue limit and drop
messages where they just queued them before. It is unfortunate
but I still think it is good to implement the routine as it was
intended. We need to review osmo_wqueue_enqueue once more to
see that no msgb is leaked.

Harald Welte d7c0a373ff logging: Extend log_target with call-back for un-formatted log line
Some targets might not want to receive only an opaque, pre-formatted
string, but rather the unformatted arguments with metadata like
sub-system/level/file/line.  We solve this by introducing a
log_target->output_raw() function pointer.  If a target specifies this
function, it takes precedence over the regular log_target->output()
function.

place a fixme comment and don't change the functionality.

Harald Welte edf6fe75b7 ctrl_cmd_parse: Make coverity FORWARD_NULL happy
The 'strtok_r' function requires passing a NULL as the first parameter
on subsequent calls in order to ensure the code picks up where it left
off on a previous call.  However, Coverity doesn't quite realize this
and points out that if a NULL was passed in as the third argument it
would result in a possible NULL deref because the strtok_r function will
assign the third argument to the first in the call is NULL.

Harald Welte aeecc48c45 Introduce osmo_strlcpy() function so we can stop using strncpy()
I'm aware of the existing criticism on stlrcpy(), but I think it is
still better than what we have now: stnrcpy(), sometimes with Coverity
warnings and sometimes with a manual setting of the termination byte.

The implementation follows the linux kernel strlcpy() which is claimed
to be BSD compatible.

We could of course link against libbsd on Linux instead, but I think
it's reasonably small and simple to provide our own implementation.
Future versions of libosmocore could use some autoconf magic and
preprocessor macros to use the system-provided strlcpy() if it exists.

to libosmocore.

Vadim Yanitskiy d2d9760c08 utils/conv_gen.py: generate a single file
Instead of generating every convolutional code into a separate
file (such as conv_xcch_gen.c, conv_cs3_gen.c), it is better to
have a single file, containing all definitions, because as many
convolutional codes we add, as many entries we will have to add
into 'src/gsm/Makefile.am'. This approach increases readability
of the Makefile.am, and also makes us able to share some data
between some convolutional code definitions.

For example: xCCH, RACH, SCH, TCH/F, both CS2 and CS3 may use
the same *_state[][2] and *_output[][2] arrays within a single
file. This optimization is currently WIP.

Neels Hofmeyr f45334be29 msgb: add msgb_talloc_ctx_init(), deprecate msgb_set_talloc_ctx()
So far each and every main() scope creates a msgb talloc context and either
passes it to msgb_set_talloc_ctx() or sets tall_msgb_ctx directly (by defining
it extern first).

Remove some code duplication: add one central function that creates the "msgb"
talloc context for all.

Most users of msgb employ a talloc_named_const(), but osmo-bts uses a
talloc_pool() instead. Offer both ways by means of the pool_size argument, and
for both ways make sure the context is called "msgb".

Suggest that msgb users should move to this new function: deprecate
msgb_set_talloc_ctx(). To be able to do so, include core/defs.h in msgb.h.

There's a tradeoff between hiding the msgb talloc context behind API that tries
to guess all use cases versus avoiding code dup. This patch opts against code
dup and boldly assumes that all future use is covered.

Also, the new function suggests to not access tall_msgb_ctx directly, which can
be considered a style improvement.

It seems that not all main scopes that use msgb actually initialize the msgb
ctx. As a fallback for these, explicitly initialize tall_msgb_ctx to NULL.

Neels Hofmeyr f0f07d9c9b osmo_sock_init(): include host and port in error messages
For programs like osmo-hnbgw with numerous sockets, the message that some
unspecified connection was refused is not very helpful. Also output the host
and port where an error occured.

Instead of perror, use fprintf(stderr, ..., strerror()) to be able to include a
format string and print host and port as passed to osmo_sock_init().
