logging_internal.h
This list is really not needed by applications and currently only used
internally in logging.c and logging_vty.c.

Projects not containing libraries may also want to contain a
TODO-RELEASE in order to write down when a new API available only on
libosmoXYZ current master (hence configure.ac and debian cannot be
updated during the patch using the API until the APIs are available in a
new release). This way, during release process of the project, the
maintainer can see that a release of libosmoXYZ is needed beforehand and
then update configure.ac of project accordingly with the new version of
libosmoXYZ.
Furthermore, we want to update the file only if mode DRY_RUN is not
selected.

The ECU implementation for FR is currently tested by calling the related
functions directly and by using the generic ECU abstraction layer. However,
the test "test_fr_concealment" only tests directly. Lets add a version
that uses the generic ECU abstraction layer as well.
The generic ECU abstraction layer obsolets the public API functions
osmo_ecu_fr_reset() and osmo_ecu_fr_conceal(), lets tag those functions
as dprecated.

Global symbol osmo_log_info is declared in logging.c as non-const,
because it is modified. As soon as logging_internal.h is included into
logging.c, the compiler warns about osmo_log_info being declared twice
differently.

I missed code review, so here are my comments in form of a follow-up patch
for Id56a1226d724a374f04231df85fe5b49ffd2c43c.
- Fix 'as_unit' arg name to 'val_unit' as in the C file and API doc.
- Explain rounding-up behavior of value conversion in API doc.
- Use osmo_tdef_get_entry() instead of a loop.

This API is already useful for users willing to set a given timer to a
given value. It will also contain code later that checks for value being
inside valid range for that timer.

As 3GPP doesn't specify how the BSC shall communicate ETWS Primary
Notifications over Abis/RSL, we have to use a vendor-specific RSL
message for this. And in order to know if the peer supports this
feature, we introduces BTS_FEAT_ETWS_PN.

We don't want to expose the details of a given ECU implementation to
the user (e.g. osmo-bts), but have a generic abstraction layer where
an ECU implementation can simply register a few call-back functions
with the generic core.
As the developer and copyright holder of the related code, I hereby
state that any ECU implementation using 'struct osmo_ecu_ops' and
registering with the 'osmo_ecu_register()' function shall not be
considered as a derivative work under any applicable copyright law;
the copyleft terms of GPLv2 shall hence not apply to any such ECU
implementation.
The intent of the above exception is to allow anyone to combine
third party Error Concealment Unit implementations with libosmocore,
including but not limited to such published by ETSI.

When a VTY closes, dispatch the VTY_CLOSED signal before tearing down the VTY
buffer and fd.
In particular this fixes:
- a crash during telnet_close_client(), invoked by the VTY_CLOSED event, which
logs to DLGLOBAL and uses vty->obuf that, so far, vty_close() had already
unallocated earlier (OS#4164).
- the logging about closing a telnet session so far logged:
DLGLOBAL INFO Closing telnet connection r=NULL<->l=NULL
By dispatching the VTY_CLOSED event while the fd is still valid, we instead
get the actual connection IP address and port being closed:
DLGLOBAL INFO Closing telnet connection r=127.0.0.1:36708<->l=127.0.0.1:4258

Rather than having applications maintain their own talloc cotexts,
let's offer some root talloc contexts in libosmocore. Let's also
make them per thread right from the beginning. This will help
some multi-threaded applications to use talloc in a thread-safe
way.

The intention of osmo_tdef_get()'s val_if_not_present argument was to return a
default timeout, or to optionally abort the program for missing timer
definitions if the default timeout is < 0. This was the case in the original
implementation of this API in osmo-bsc, but in the migration to libosmocore,
the argument was by accident changed to an unsigned type. In consequence, the
assertion in the implementation that was intended to abort the program seemed
bogus to coverity, and was fixed by removal in
I7a544d2d43b83135def296674f777e48fe5fd80a -- the wrong direction, as is obvious
from the API doc for osmo_tdef_get().
Note that osmo-bsc master passes -1 in various places and expects the
program-abort behavior that was missing from the libosmocore implementation.
Change the val_if_not_present argument to a signed type, and revert removal of
the assertion, so that passing -1 has the effect described in the API doc:
program abort on missing timer definition.
This bug was not detected because it is hard to write tests that expect a
program abort to happen, hence no tests for this API feature exist.

When reading SUT logs resulting from TTCN3 runs, it can be hard to figure out
which log section corresponds to which test code. Add a 'logp' command on VIEW
and ENABLE nodes that simply echos an arbitrary message on log output, useful
to set markers / explanations from the TTCN3 code, which then appear in all log
outputs and can make it trivial to figure out which log section is interesting.
logging_vty_test# logp lglobal notice This is the log message
DLGLOBAL NOTICE This is the log message
From TTCN3, could be used like this, e.g. in BSC_Tests.ttcn:
private function f_logp(charstring log_msg) runs on MSC_ConnHdlr
{
// log on TTCN3 log output
log(log_msg);
// log in stderr log
f_vty_transceive(BSCVTY, "logp lglobal notice " & log_msg);
}
...
f_logp("f_probe_for_handover(" & log_label & "): Ending the test: Handover Failure stops the procedure.");

This option allows testing if everything is in place before attempting

It's also useful during development of the osmo-release.sh release
itself, sine it makes test iterations faster (no need to undo actions
done).

As a result whitespace ended up in some variables and then command
"expr" was not happy about it.
It was spotted because src/coding/Makefile.am had some whitespacing.
Since it's the only one, let's drop the whitespace there too to have
similar line in all Makefile.am files.

Some toolchains (such as sysmobts 201705 one) containing the TLS bug on
old ARM gcc versions (<7.3.0) also crash if the initial workaround found
is aplied (CFLAGS="-mtls-dialect=gnu2"). In that scenario, let's provide
a way to disable the workaround (to avoid "ld" crashing) and warn the
user about requirement to build with -O0 to avoid runtime crashes.

Check if compiler being used contains the bug. GCC 7.3.0 is the oldest
version containing the fix, and version 6.3.0 is known to contain the
bug. Bug is only known to appear so far only on ARM32. If the bug is
present, gcc will generate a wrong binary which wil lend up segfaulting
when accessing TLS (__thread) variables under certain conditions.

Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However,
definition in C file doesn't contain "(void)", which means number of
parameters is undefined and thus compiler doesn't complain. Let's remove
parameters from all callers before enforcing "(void)" on it.

There's no real good reason for using that function (static buffer)
instead of osmo_str_tolower_buf(local buffer), so let's use the later.
In any case, we get rid of TLS variables in those places, which is a
performance improvement.
It will also allow later shrinking of those buffers if we decide to
define maximum logging category and level name length.

This way we get rid of extra 128 bytes in memory per thread created.
It makes sense to share the buffer since it's same size and it doesn't
make much sense to be using both osmo_str_tolower and osmo_strtoupper at
the same time (usually you either want to move everything to uppercase
or everything to lowerase). In required scenarios, one can still use the
_buf versions.

After reading data from the socket, assigned to a given VTY, we
need to '\0'-terminate the received string. Otherwise, further
access to that string, stored in a heap buffer vty->buf, would
lead to a heap overrun.

== Why exactly 512?
Because the initial size of the heap buffer is 512 (see VTY_BUFSIZ).
Later on it can be realloc()ated, so X > 512 should also work.

After recent system upgrade, gcc 9.1.0, I started getting gsm0808_test
failing locally:
Assert failed memcmp(&enc_ct, &dec_ct, sizeof(enc_ct)) == 0 libosmocore/tests/gsm0808/gsm0808_test.c:992
During investigation with gdb, fields of both structures seem to contain
same values. However, closer lookup gives some hints on why it fails:
(gdb) print memcmp(&enc_ct, &dec_ct, sizeof(enc_ct))
$1 = 85
(gdb) print memcmp(&enc_ct, &dec_ct, 12)
$14 = 85
(gdb) print ((uint8_t*)&enc_ct)[11]
$15 = 85 'U'
(gdb) print ((uint8_t*)&dec_ct)[11]
$16 = 0 '\000'
So the 12th byte in struct gsm0808_channel_type is basically an
alignment padding byte added by the compiler (to align perm_spch_len to
4-byte alignment). Since both compared structs are initialized without
memset(0) but using compiler's designated initializers, it seems the compiler
decided it's no longer needed to zero the padding byte, making memcp fail in
this case.
In order to avoid the failure, let's properly check every field instead
of using memcp here.

Unconditional initialization follows the structure definition,
so there is no need to do it twice. This prevents compiler
from warning about potential errors.

ubsan will report undefined behavior due to the SUN_LEN macros interaction with a null pointer,
so let's tell ubsan to ignore this function. After carefully reviewing the final publically
availlable drafts of the C99,C11 and C18 standards I can confirm that dereferencing null pointers
is still undefined behavior, as such ubsan will always warn with absolutely every existing compiler
version. Since the sanitizers are periodically synced between llvm and gcc I'm also fairly confident
that rebuilding everything with compiler_rt to use the integrated sanitizers would result in the same message.
I sincerly hope that this explanation provides to be sufficient, If not I'd be willing to show up at
the next llvm dev meeting to provide quotes from actual sanitizer developers to back up these claims.
