Make build and external tests work with python3, so we can drop
the python2 dependency.
This should be merged shortly after osmo-python-tests was migrated to
python3, and the jenkins build slaves were (automatically) updated to
have the new osmo-python-tests installed.

The new OSMO_DEPRECATED_OUTSIDE macro is similar to the existing
OSMO_DEPRECATED_OUTSIDE_LIBOSMOCORE, but allows to override the
deprecation message.
Let's use it to suspend deprecation warnings related to:
- gsm48_decode_bcd_number(),
- osmo_ecu_fr_conceal(),
- osmo_ecu_fr_reset(),
as they're intentionally used in scope of the library.

This is a bit of a hack, as we want to maintain binary compatibility
without breaking existing users of libosmocore. To do so, we use the
'num_auth_vectors' field in two ways now:
* In the existing use case as part of SEND_AUTH_INFO_RESPONSE, it
indicates the number of vectors stored in the 'auth_vectors' field
* In the new use case as part of SEND_AUTH_INFO_REQUEST, it indicates
the number of vectors actually requested by the MSC/SGSN/MME.

OSMO_GSUP_TO_MSGT_RESULT() is needed by osmo-hlr for osmo_gsup_req.
The others are added for completeness' sake.

Provide string escaping that
- returns the required buffer size, so it can be used with OSMO_STRBUF_APPEND().
- uses C compatible string constant escaping sequences.
This is intended as a replacement for all previous osmo_escape_str* and
osmo_quote_str* API. It pains me that I didn't get them right the first nor the
second time:
- The buffer functions do not return the chars needed, which is required for
allocating sufficient memory in the *_c versions of the functions.
- Because of that, these functions are accurately usable for
OSMO_STRBUF_APPEND(), producing truncated strings, for example when dumping a
GSUP message.
- They do not use the C equivalent string constant escaping: for some reason I
thought "\15" would be valid, but it should be "\x0f".
If I could, I would completely drop those mislead implementations ... but
backwards compat prohibits that.
A previous patch already provided internal static functions that accurately
return the required buffer size. Enhance these to also support C compatible
string escaping, and use them as implementation of the new functions:
osmo_escape_cstr_buf()
osmo_escape_cstr_c()
osmo_quote_cstr_buf()
osmo_quote_cstr_c()
In the tests for these, also test C string equivalence.
Naming: from API versions, it would be kind of logical to call them
osmo_escape_str_buf3() and osmo_escape_str_c2(). Since these anyway return a
different escaping, it makes sense to me to have distinct names instead.
Quasi missing are variants of the non-C-compatible weird legacy escaping that
return the required buffer size, but I refrain from adding those, because we
have enough API cruft as it is. Just always use these new cstr variants.

Although this OSMO_DEPRECATED doesn't seem to generate a warning when compiling
code that sets .is_config_node = foo, it seems a good idea to add the
deprecation tag.
It is deprecated since commit "vty: track parent nodes also for telnet sessions"

Keep track of parent nodes and go back hierarchically, not only for .cfg file
reading, but also for telnet VTY sessions.
A long time ago cfg file parsing was made strictly hierarchical: node exits go
back to parent nodes exactly as they were entered. However, live telnet VTY
sessions still lacked this and depended on the go_parent_cb().
From this commit on, implementing a go_parent_cb() is completely optional. The
go_parent_cb() no longer has the task to determine the correct parent node,
neither for cfg files (as already the case before this patch) nor for telnet
VTY sessions (added by this patch). Instead, a go_parent_cb() implementation
can merely take actions it requires on node exits, for example applying some
config when leaving a specific node.
The node value that is returned by the go_parent_cb() and the vty->node and
vty->index values that might be set are completely ignored; instead the
implicit parent node tracking determines the parent and node object.
As a side effect, the is_config_node() callback is no longer needed, since the
VTY now always implicitly knows when to exit back to the CONFIG_NODE.
For example, osmo_ss7_is_config_node() could now be dropped, and the
osmo_ss7_vty_go_parent() could be shortened by five switch cases, does no
longer need to set vty->node nor vty->index and could thus be shortened to:
int osmo_ss7_vty_go_parent(struct vty *vty)
{
struct osmo_ss7_asp *asp;
struct osmo_xua_server *oxs;
switch (vty->node) {
case L_CS7_ASP_NODE:
asp = vty->index;
/* If no local addr was set */
if (!asp->cfg.local.host_cnt) {
asp->cfg.local.host[0] = NULL;
asp->cfg.local.host_cnt = 1;
}
osmo_ss7_asp_restart(asp);
break;
case L_CS7_XUA_NODE:
oxs = vty->index;
/* If no local addr was set, or erased after _create(): */
if (!oxs->cfg.local.host_cnt)
osmo_ss7_xua_server_set_local_host(oxs, NULL);
if (osmo_ss7_xua_server_bind(oxs) < 0)
vty_out(vty, "%% Unable to bind xUA server to IP(s)%s", VTY_NEWLINE);
break;
}
return 0;
}
Before parent tracking, every program was required to write a go_parent_cb()
which has to return every node's parent node, basically a switch() statement
that manually traces the way back out of child nodes. If the go_parent_cb() has
errors, we may wildly jump around the node tree: a common error is to jump
right out to the top config node with one exit, even though we were N levels
deep. This kind of error has been eliminated for cfg files long ago, but still
exists for telnet VTY sessions, which this patch fixes.
This came up when I was adding multi-level config nodes to osmo-hlr to support
Distributed GSM / remote MS lookup: the config file worked fine, while vty node
tests failed to exit to the correct nodes.

GSUP routing was introduced when adding the E interface. Hence that was the
first realm where routing errors could occur. I did notice back then that this
message type was special: it does not convey a response to a particular message
kind -- it does not make sense, for example, to return an Updating Location
Error cause, and do that for all conceivable message types. Instead, this tells
the sender that a deeper error exists, i.e. that the desired peer is completely
gone and unreachable.
I did not foresee though that for D-GSM, there would also be arbitrary GSUP
proxy routing, and that this error is not limited to E interface semantics.
From today's point of view, adding the "_E_" in the name was a mistake.
Remove that "_E_" to yield OSMO_GSUP_MSGT_ROUTING_ERROR (with unchanged message
type discriminator), but provide a #define linking the old name
OSMO_GSUP_MSGT_E_ROUTING_ERROR to the new one.
The only visible change should be that osmo_gsup_message_type_names[] now
returns the new name without "_E_". I am not aware of any regression test
fallout from that.

Provide a common implementation for foo_name_c() functions that base on
foo_name_buf() functions.
char *foo_name_c(void *ctx, example_t arg)
{
OSMO_NAME_C_IMPL(ctx, 64, "ERROR", foo_name_buf, arg)
}
Rationale: the most efficient way of composing strings that have optional parts
or require loops for composition is by writing to a ready char[], and this in
turn is easiest done by using OSMO_STRBUF_* API. Using such a basic name string
implementation which typically returns a length, I often want a more convenient
version that returns a char*, which can just be inlined in a "%s" string format
-- crucially: skipping string composition when inlined in a LOGP(). This common
implementation allows saving code dup, only the function signature is needed.
Why not include the function signature in the macro? The two sets of varargs
(1: signature args, 2: function call args) are hard to do. Also, having an
explicit signature is good for readability and code grepping / ctags.
Upcoming uses: in libosmocore in the mslookup (D-GSM) implementation
(osmo_mslookup_result_name_c()), and in osmo_msc's codec negotiation
implementation (sdp_audio_codecs_name_c(), sdp_msg_name_c(), ...).

It's hard to figure out what color logging categories have with those ANSI
color code strings. Instead, define these OSMO_LOGCOLOR_* constants.
Naming: commonly, the logging.h header has the "LOG" prefix in the name, but it
seems saner to include the OSMO_ prefix: it seems too likely that some
libosmocore user somewhere already has defined "LOGCOLOR_RED" somewhere.

Often, an IP address of 0.0.0.0 is considered an unset value (for clients
requiring a server address; not for listening on "any").
osmo_sockaddr_str_is_set() does return false when the port is 0, but there is
no simple way to tell whether the IP address is actually set to a server
address.
Add osmo_sockaddr_str_is_nonzero() to return false if:
- the port is zero, or
- the IP address is zero (0.0.0.0 or ::0), or
- the IP address cannot be parsed.
A practical use example: osmo-msc so far accepts an RTP IP address of 0.0.0.0
as valid. I noticed when trying to trigger error handling from a ttcn3 test.
osmo-msc can use this function to reject invalid addresses from MGCP messages.

This is a simpler and more general solution to the problem so far solved by
osmo_fsm_term_safely(true). This extends use-after-free fixes to arbitrary
functions, not only FSM instances during termination.
The aim is to defer talloc_free() until back in the main loop.
Rationale: I discovered an osmo-msc use-after-free crash from an invalid
message, caused by this pattern:
void event_action()
{
osmo_fsm_inst_dispatch(foo, FOO_EVENT, NULL);
osmo_fsm_inst_dispatch(bar, BAR_EVENT, NULL);
}
Usually, FOO_EVENT takes successful action, and afterwards we also notify bar.
However, in this particular case, FOO_EVENT caused failure, and the immediate
error handling directly terminated and deallocated bar. In such a case,
dispatching BAR_EVENT causes a use-after-free; this constituted a DoS vector
just from sending messages that cause *any* failure during the first event
dispatch.
Instead, when this is enabled, we do not deallocate 'foo' until event_action()
has returned back to the main loop.
Test: duplicate fsm_dealloc_test.c using this, and print the number of items
deallocated in each test loop, to ensure the feature works. We also verify that
the deallocation safety works simply by fsm_dealloc_test.c not crashing.
We should probably follow up by refusing event dispatch and state transitions
for FSM instances that are terminating or already terminated:
see I0adc13a1a998e953b6c850efa2761350dd07e03a.

log_enable_multithread() enables use of locks inside the
implementation. Lock use is disabled by default, this way only
multi-thread processes need to enable it and suffer related
complexity/performance penalties.
Locks are required around osmo_log_target_list and items inside it,
since targets can be used, modified and deleted by different threads
concurrently (for instance, user writing "logging disable" in VTY while
another thread is willing to write into that target).
Multithread apps and libraries aiming at being used in multithread apps
should update their code to use the locks introduced here when
containing code iterating over osmo_log_target_list explictly or
implicitly by obtaining a log_target (eg. osmo_log_vty2tgt()).

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.

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.
