Vadim Yanitskiy e65c8bad46 vty/command.h: document and prettify CMD_ATTR_* flags
Since the CMD_ATTR_* flags are intended to be used in bitwise
operations, let's assign them proper values. Adding a new flag
(e.g. CMD_ATTR_FOO_BAR) could actually result in assigning 0x03
instead of expected (0x01 << 2).

Philipp Maier 5f2eb15074 gsm0808: add function to convert amr gsm0408 setings to gsm0808
Add a function to convert struct gsm48_multi_rate_conf, which holds the
codec settings for AMR, to S0-S15 bit representation as defined in
3GPP TS 48.008 3.2.2.49

This resurrects change-id I4e656731b16621736c7a2f4e64d9ce63b1064e98
which was reverted in I9e0d405e303ed86d23703ca6362e958dddb2f861
due to gsm0808_test failing.

The test failure is fixed by properly clearing the struct
gsm48_multirate_cfg prior to running tests (add memset(0)).

Philipp Maier 4b081b1d88 gsm0808: fix wrong codec defaults for OFR_AMR_WB
3GPP TS 48.008 chapter 3.2.2.103 states that the configuration bits of
OFR_AMR_WB are coded as follows:

"S0, S2, S4 indicates the supported Codec Configurations. S1, S3, S5, S6,
S7 are reserved and coded with zeroes."

The current default setting of 0x3F violates this requirement. Lets set
the "forbidden" settings zu zero and keep only the allowed ones.

Neels Hofmeyr ba0762d6cb logging vty: rewrite 'logging level' vty cmd generation
Completely drop the implementations of log_vty_command_{str,description}().
These functions have been public API once, marked as deprecated since
c65c5b4ea0 (March 2017). I considered to keep
them, or reduce them to useless stubs, but it is quite silly, really. These
functions are completely and utterly useless outside of libosmocore. Any
program linking these deserves to fail.

Re-implement vty logging level command gen, in logging_vty.c. logging.c is
simply the wrong place for that.

Introduce logging_internal.h to share logging definitions to logging_vty.c
without publishing as API.

Introduce static gen_logging_level_cmd_strs() to compose a list of category
arguments with their descriptions for VTY commands. Use osmo_talloc_asprintf()
instead of the previous error prone and chaotic strlen() counting method.

Do not dynamically generate log level arguments, just keep static strings. We
are super unlikely to ever change the log levels we have.

No changes in logging_vty_test.vty: proves that there is no functional change.

All of this, besides introducing basic sanity, is cosmetic preparation to be
able to re-use the generic command generation code for arbitrary commands with
category or level args (for deprecated and new keywords).

Rationale: I want to hide 'all' and 'everything' from the VTY command
documentation, by means of deprecating. I first tried to simply define a
deprecated 'logging level CAT everything' command:

  logging level (all|rsl|rr|...) (debug|info|notice|error|fatal)
  logging level CAT everything                   # <- deprecated and hidden

But unfortunately, command matching doesn't work as intended when the CAT
argument reflects a valid category; I want it to invoke the deprecated function
as soon as the 'everything' keyword follows, but it stays stuck to the "valid"
command when the category argument matches an explicit keyword in that list,
and will throw an error on the following 'everything' keyword. I.e.:

  logging level rsl everything
  % Unknown command  # <-- leads to config file parse error

  logging level unknown_string everything
  % Ignoring deprecated 'everything'  # <-- works only for invalid categories

So I need to define 'everything' separately, again with a list of each valid
category instead of a generic CAT arg.

Neels Hofmeyr 7c749893bf add osmo_str_tolower() and _toupper() with test
We already have osmo_str2lower() and osmo_str2upper(), but these lack:
* proper destination buffer bounds checking,
* ability to call directly as printf() argument.

Deprecate osmo_str2upper() and osmo_str2lower() because of missing bounds
checking.

Introduce osmo_str_tolower_buf(), osmo_str_toupper_buf() to provide
bounds-safe conversion, also able to safely convert a buffer in-place.

Introduce osmo_str_tolower(), osmo_str_toupper() that call the above _buf()
equivalents using a static buffer[128] and returning the resulting string
directly, convenient for direct printing. Possibly truncated but always safe.

Add unit tests to utils_test.c.

Replace all libosmocore uses of now deprecated osmo_str2lower().

Naming: the ctype.h API is called tolower() and toupper(), so just prepend
'osmo_str_' and don't separate 'to_lower'.

Neels Hofmeyr 77ae45d22f log: add 'last' option to 'logging print file'
Allow printing the source file information *after* the log information.

Add target->print_filename_pos, log_set_print_filename_pos() and enum
log_filename_pos, and the optional 'last' keyword to the 'logging print file'
vty command. (An enum in case we want to add other positions later.)

Rationale: on log lines, the logging context is usually printed first in the
logging text. Without the source file information, this logging context pretty
much aligns in an easily readable way. When adding the source file information,
each line's logging context info is shifted right by a pretty much random
amount and it is hard to spot recurring logging contexts.

One solution is to switch off source file info, of course, but that's not an
option when actively hacking on bugs and new features.

For example, it is unnecessarily hard to spot lchan FSM related log lines in
this osmo-bsc log snippet:

Placing the source file info behind the log text makes it much easier to

Implementation: for 'last', insert source file info only when an '\n' is found
at the end of the log line composition buffer, so that LOGP()...LOGPC()
constructs also print source file info only when a log line actually ends.

Philipp Maier 73196e77fb socket: add flag to enforce SO_REUSEADDR on UDP sockets
When IPPROTO_UDP is used then SO_REUSEADDR omitted since UDP is
connection less we do not have to wait until lingering connections time
out. There were also negative effects such as that two applicatications
could use the same UDP port, normally one of the two applications would
get an error, but with SO_REUSEADDR this is supressed. However, there
are applications (UDP MULTICAST) where two applications must be able to
use the same port. In the osmocom project those are osmo-bts-virtual,
virtphy and gsmtap in general.

Lets introduce a flag that the API user can supply in order to have
SO_REUSEADDR applied.

- Add new flag OSMO_SOCK_F_UDP_REUSEADDR

Neels Hofmeyr 983dcb9af3 use __FILE__, not __BASE_FILE__
The intention was to use the file's basename, but __BASE_FILE__ means "the root
file that is being parsed and contains #include statements".

If we had a function using __BASE_FILE__ and that was defined in an #included
file, __BASE_FILE__ would indicate the first file where the #include is, and
not the file where the function is defined. __BASE_FILE__ works for us because
we don't ever include function definitions that log something, so __BASE_FILE__
always coincides with __FILE__ for our logging; but still __BASE_FILE__ is
semantically the wrong constant.

It's a common pattern having a list of msgb and having to maintain its

counter updated at the same time that the msgb is enqueued or dequeued
helps avoiding introducing new bugs by forgetting to update the size
counter at the right places.

for messages, where the transaction identifier is required
(see GSM 04.07, section 11.2.3.1.2).

Harald Welte 7869baf843 Deprecate ipa_ccm_idtag_parse() with ipa_ccm_id_{get,resp}_parse()
In the past, the function ipa_ccm_idtag_parse() was used to parse
the payload of IPA CCM ID RESP packets.  However, the function was
based on a possible misunderstanding of the message encoding, and
callers actually counted the first (upper) length nibble as part
of the header and passed a pointer to the second
(lower) length nibble of the first TLV into this function.  As such,
it was unfixable, and had to be replaced with a new function called
ipa_ccm_id_resp_parse().  At the same time, we also add
ipa_ccm_id_get_parse() to parse the slightly different format of
the IPA CCM ID GET payload.

We can never be 100% sure what is "correct", as our understanding
of the protocol is entirely based on protocol analysis, without any
official documentation available.

This patch also introduces unit test coverage for both of the new
functions.

Revert "ipa: Add libosmogsm.map entry for ipa_ccm_idtag_parse_off"
This reverts commit 7f31c90b80.

Revert "ipa: Properly parse LV stream of a ID_GET request"
This reverts commit f558ed4bb9.

It introduced a function/behavior that was not originally intended:
The parse of IPA CCM ID GET (8bit length followed by 1 byte tag
and variable-length payload) instead of the IPA CCM ID RESP (16bit
length followed by 1 byte tag and variable-length payload).

Kevin Redon 0bc3b83654 GSMTAP: add SIM sub_types
In SIMtrace 1 the ATR was sent the same way as an APDU.
The ATR is not an APDU, and could be mis-interpreted as valid APDU.
This change allows to make the difference between actual APDU and
the ATR, but also adds sub_types for future SIMtrace 2 use cases.

The conv_gen.py utility was tested against both Python 2 and 3,
so there is no need to enforce Python 2. Also, having:

  #!/usr/local/bin/python{2|3}

is a bad idea, because Python may be installed in a different location.

In Change-Id I5a70eb65952cbc329bf96eacb428b07a9da32433 we redirected
all OSMO_ASSERT() via osmo_panic().  However, this caused various

to be able to return to the call site.  Let's inform the compiler
explicitly that there's no return from osmo_panic().

A loooong time ago, we introduced osmo_panic() as a wrapper around
abort().  The advantage is, that this wrapper can be overridden, and
that it will also work in embedded (bare iron) targets, where the
abort simply translates to an infinite loop.

  - adding the 'gsm0480_' prefix;
  - correcting inverted return value;
  - cosmetic code style changes.

Harald Welte 11eb4b5add vty: Add logging_vty_add_deprecated_subsys
This function permits the user to register deprecated log categories,
which will ensure that if log categories are removed from a program,
old config files will still load.

We simply dynamically allocate a cmd_element and install it at
CFG_LOG_NODE.  Not registering it at VIEW_NODE or ENABLE_NODE
ensures that it's not accessible from the interactive VTY, but only
from the config file / configure node.

Harald Welte 3385e4b0c4 fsm: Change semantics of LOGPFSML() log-level
The general idea about each osmo_fsm_instance having a separate
log-level was to be able to selectively increase/show/enable logging
for some FSM instances (e.g. of a particular subscriber) while
maintaining normal logging verbosity for all other instances of the
same FSM.

The introduction of LOGPFSML() in Change-Id
If295fdabb3f31a0fd9490d1e0df57794c75ae547 broke that idea, as it would
use a compile-time log level, irrespective of the
osmo_fsm_inst.log_level setting of the given instance.

Let's combine the two:
Use the explicit level stated at LOGPFSML(), _unless_ this instance
has a higher log_level configured.

This way, all FSMs should normally be created with
osmo_fsm_inst.log_level == LOGL_DEBUG.  At that point LOGPFSM()
statements would be rendered at debug level, typically below the
threshold of most logging configurations.

Code that has explicit higher log levels like LOGPFSML(fi, LOGL_ERROR)
would always be printed, as it is an error message.

And if we now increase the osmo_fsm_inst.log_level, then even the normal
LOGPFSM() statements would suddenly be logged at that higher level,
selectively increasing log verbosity - like originally intended.
