Neels Hofmeyr 9a4286b709 gsm0808_test: fix more missing inits (address sanitizer issues)
In recent Iaa20c59f624fbdc69a018cabd0f7e9c5a1389519 I fixed one missing init
issue and didn't notice the N other similar ones right next to it. Also fix the
remaining missing inits.

Fixes:

    ../../../../src/libosmocore/src/gsm/gsm0808_utils.c:191:8: runtime error: load of value 119, which is not a valid value for type '_Bool'

Harald Welte 542301b067 RSL/LAPDm: Not all RLL message are "transparent"
3GPP TS 48.058 has a very clear definition of which messages are
"transparent" and hence have the T-bit == 1.  This is *not* just
all RLL messages, but basically only RLL_DATA.{ind,req} and
RLL_UNITDATA.{ind,req}.  All other messages are non-transparent.

Neels Hofmeyr a4399c8891 add gsm0808_cell_{id,id_list}_name() and friends
Provide comprehensive API to obtain string representations of Cell Identifiers
and -Lists.

Change gsm0808_test.c to use the new functions (which simplifies the output a
bit), so that we don't duplicate printing code in gsm0808_test.c, and so that
the not-so-trivial printing code is also tested.

In gsm0808_test, also test gsm0808_cell_id_list_name_buf()'s return value and
truncation behavior.

The rationale for gsm0808_cell_id_list_name(), i.e. printing an entire list of
cell identifiers, is that even though the maximum is 127 elements, a list of
more than a few elements is hardly ever expected in practice (even more than
one element isn't actually expected: either "entire BSS" or a single LAC). It
is thus useful to log the entire list when it shows up in Paging and Handover.

Neels Hofmeyr c62c934647 test_gsm0808_enc_dec_speech_codec_with_cfg: initialize properly
The uninitialized members of enc_sc sporadically hit address sanitizer failure
during gsm0808_test, like:
../../../../src/libosmocore/src/gsm/gsm0808_utils.c:187:8: runtime error: load of value 13, which is not a valid value for type '_Bool'
../../../../src/libosmocore/src/gsm/gsm0808_utils.c:191:8: runtime error: load of value 119, which is not a valid value for type '_Bool'

How the test survived so long is a mystery to me; as soon as some uninitialized
members would by coincidence not be zero, the test should always have failed at
OSMO_ASSERT(memcmp(&enc_sc, &dec_sc, sizeof(enc_sc)) == 0).

Neels Hofmeyr 250e7f7d30 add gsm0808_{enc,dec}_cell_id
Clarify semantics and micro-optimise for the case of single Cell Identifer IEs.
Test in gsm0808_test.c

So far we have gsm0808_enc_cell_id_list2(), but there also exist instances of
single Cell Identifiers (3GPP TS 48.008 3.2.2.17).

It is possible to decode the same using the cell identifier list API, but this
forces the caller to also keep a full struct gsm0808_cell_id_list2 with all its
127 entries around.

E.g. for handover, there are two Cell Identifiers (Serving and Target); I'd
need two full cell id lists for each, and these would be dynamically allocated
for each handover operation, whether it uses them or not.

Neels Hofmeyr a78b22ba20 add tlv_parse2(), capable of multiple instances of the same IE
Allow passing multiple struct tlv_parsed in an array, to allow parsing as many
repeated IEs as are expected by the caller.

From tlv_parse(), call tlv_parse2() with dec_multiple = 1 to yield the previous
behavior. tlv_parse() remains valid API.

An example of multiple IEs is the BSSMAP Handover Request, containing Cell
Identifier (Serving) and Cell Identifier (Target), both defined by 3GPP TS
48.008 3.2.2.17 with identical IE tags; both are mandatory.

It will also be useful to accumulate cell identifiers in case a subscriber sees
multiple alternative cells from a neighboring BSS, and we want to pass these on

Add a test that actually allocates an FSM instance with a NULL id, which is
allowed, but uncovers a bug of an unset FSM instance name. osmo_fsm_inst_name()
falls back to the fsm struct's name on NULL, but osmo_fsm_inst_find_by_name()
fails to match if the instance's name is NULL (and until recently even
crashed). Show this in fsm_test.c with loud comments.

Rather clean up the instance and hence also test that, by using a global flag

Neels Hofmeyr 04eb56f146 add osmo_quote_str(),osmo_quote_str_buf() and test
Rationale: with osmo_escape_str(), you get the escaped contents of the string,
but not so graceful handling of NULL strings. The caller needs to quote it, and
for NULL strings not quote it.

osmo_quote_str() is like osmo_escape_str() but always quotes a non-NULL string,
and for a NULL string returns a literal NULL, i.e. it should (tm) give the
exact C representation of a string.

That's useful in testing, to show exactly what char* situation we have, without
jumping through hoops like
  if (str)
  	printf("\"%s\"", osmo_escape_str(str, -1));
  else
  	printf("NULL");

Copy the unit test for osmo_escape_str() and adjust. To indicate that the
double quotes are returned by osmo_quote_str(), use single quotes in the test
printf()s.

I considered allowing to pick the quoting characters by further arguments, but
that complicates things: we'd need to escape the quoting characters. Just
hardcode double quotes like C.

Neels Hofmeyr cdbc9afe5d ctrl: fix deferred commands (and hence fix osmo-bts-sysmo 'clock-info' cmd)
The CTRL interface has a ctrl_cmd_def_* API that allows deferring a CTRL
command reply until later. However, the command handling currently fails to
acknowledge this and deallocates the struct ctrl_cmd anyway.

Fix: in struct ctrl_cmd, add a defer pointer to be populated by
ctrl_cmd_def_make(). A cmd thus marked as deferred is not deallocated at the
end of command handling. This fix needs no change in calling code.

(Another idea was to return a different code than CTRL_CMD_HANDLED when the
command is to be deferred, but that would require adjusting each user of
ctrl_cmd_def_make(). The implicit marking is safer and easier.)

Show that handling deferred commands is fixed by adjusting the expectations of
ctrl_test.c's test_deferred_cmd() and removing the now obsolete exit_early
label.

One symptom of the breakage is that osmo-bts-sysmo crashes when asked to report
a trx's clock-info, which is aggravated by the fact that the sysmobts-mgr does
ask osmo-bts-sysmo for a clock-info.

The crash appears since Id583b413f8b8bd16e5cf92a8a9e8663903646381 -- it looked
like just fixing an obvious memory leak, which it did as shown by the unit
test, but deferred ctrl commands actually relied on that leak. Both fixed now.

Neels Hofmeyr 473485c903 gsm0808_test: cosmetic: test non-hex MCC
The test currently sets the MCC by a hex value, which is a weird choice. The
MCC gets BCD'd and hence we will see the decimal values 1:1 in the encoded
octets as hex digits. Using hex as input obscures that:

Right now it sets mcc = 0x123, which is actually 291 in decimal, and we hence
see "92 .1" in the expected BCD result. Using 0x124 in the test source actually
makes it hard to see where the 0x123 went.

Change the MCC to decimal notation (123, 124, 125) and adjust the expected
encoded output.

Stefan Sperling e1a86748a2 fix cell identifier decoding in libosmocore
The cell ID list decoder merged in 11a4d9dd91
has a bug which was introduced part-way through the review process in
gerrit at https://gerrit.osmocom.org/#/c/6509/

When Neels suggested "why not just {...}id_list[MAXLEN] once?" I changed
the cell identifier list from a union of arrays to an array of unions.

After this change, elements smaller than the largest type in the union
were not laid out consecutively in memory anymore. E.g. uint16_t lac
values now occur at offsets of sizeof(id_list[0]) instead of offsets
of sizeof(uint16_t).

The problem is that I forgot to adjust the decoder accordingly, so the
decoder writes to the wrong offsets and returns cell identifier lists
which appear to contain uninitialized values when read back by API
consumers.

I found this problem while adding new regression tests to libosmocore to
test encoding and decoding. This commit adds one such tests for LAC list
decoding, which failed due to the above bug. I plan to write more tests,
however because this first test already uncovered a severe issue I chose
to submit a fix now and work on additional tests in later commits.

Stefan Sperling 11a4d9dd91 support for more cell ID list types in libosmocore
Introduce gsm0808_dec_cell_id_list2() with supports additional types of
cell identifier lists. The new parsing routines are based on similar
routines used by the paging code in osmo-bsc's osmo_bsc_bssap.c.

Likewise, introduce gsm0808_enc_cell_id_list2() with support for the
same additional types of cell identifier lists.

The old API using struct gsm0808_cell_id_list is deprecated.
The previous definition was insufficient because it assumed that all
decoded cell ID types could be represented with a single uint16_t.
It was declared in a GSM protocol header (gsm/protocol/gsm_08_08.h)
despite being a host-side representation of data in an IE.
The only user I am aware of is in osmo-msc, where this struct is used
for one local variable. osmo-msc releases >= 1.1.0 make use of this API.

While here, fix a small bug in a test:
test_gsm0808_enc_dec_cell_id_list_bss() set the cell ID type to 'LAC'
but obviously wants to use type 'BSS'.

if the MNC is anyway >99. Will be used by osmo-sgsn.git and osmo-bsc.git.  (All
current users just care about identical MNC, but a proper cmp doesn't hurt.)

Stefan Sperling 888dc7d31a print BIG FAT ERROR message if osmo_fsm lacks event names
Event names are displayed in VTY commands so all FSM should have them.
Print an error message if an FSM is registered without event names.
We could also return an error code, however at present no caller checks
the return value of osmo_fsm_register() so this would be pointless.

Add event names to the test FSM and update expected output accordingly.

When running with -O0 it seems the compiler (gcc 7.2.1) decides to use
the external linkage but at the same time it seems it's not generating
the function symbol. Fix it by explicitly stating that we want to use
static linking for this function.

Vadim Yanitskiy bd33a9568e tests/ussd: prevent uninitialized memory access
Previously an incorrect length value was passed to both
gsm_7bit_decode_n_ussd() and gsm_7bit_encode_n_ussd()
functions during test_7bit_ussd() execution, due to:

   octets_written = strlen(decoded);

The problem is that a 7-bit encoded string takes less memory
than its 8-bit equivalent. So, here strlen() returns one-byte
bigger value, that octets_written is. This then causes the
uninitialized memory access.

Found using Valgrind:

Neels Hofmeyr 554f7b8a77 rate_ctr: fix osmo-sgsn DoS: don't return NULL on already used index
Recent patch I563764af1d28043e909234ebb048239125ce6ecd introduced returning
NULL from rate_ctr_group_alloc() when the index passed already exists.

Instead of returning NULL, find an unused group index and use that, adjust the
error message.

In stats_test.c, adjust, and also assert allocated counter group indexes
everywhere.

Rationale:

The original patch causes osmo-sgsn to crash as soon as the second subscriber
attempts to establish an MM context. Of course osmo-sgsn is wrong to a) fail to
check a NULL return value and crash and b) to fail to allocate an MM context
just because the rate counter group could not be allocated (it still rejects
the MM context completely if rate_ctr_group_alloc() fails).

Nevertheless, the price we pay for rate counter correctness is, at least in
this instance, way too high: osmo-sgsn becomes completely unusable for more
than one subscriber.

Numerous other places exist where rate_ctr_group_alloc() is called with a
constant index number; from a quick grep magic I found these possible breaking
points:

osmo-sgsn/src/gprs/gb_proxy.c:1431:     cfg->ctrg = rate_ctr_group_alloc(tall_bsc_ctx, &global_ctrg_desc, 0);
osmo-sgsn/src/gprs/gprs_sgsn.c:139:     sgsn->rate_ctrs = rate_ctr_group_alloc(tall_bsc_ctx, &sgsn_ctrg_desc, 0);
osmo-sgsn/src/gprs/gprs_sgsn.c:270:     ctx->ctrg = rate_ctr_group_alloc(ctx, &mmctx_ctrg_desc, 0);
osmo-sgsn/src/gprs/gtphub.c:888:        b->counters_io = rate_ctr_group_alloc(osmo_gtphub_ctx,
                                                                              &gtphub_ctrg_io_desc, 0);
osmo-bsc/src/libfilter/bsc_msg_acc.c:87:        lst->stats = rate_ctr_group_alloc(lst, &bsc_cfg_acc_list_desc, 0);
osmo-pcu/src/bts.cpp:228:               m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:793:       tbf->m_ctrs = rate_ctr_group_alloc(tbf, &tbf_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:879:       tbf->m_ul_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_egprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:880:       tbf->m_ul_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_gprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:970:               tbf->m_dl_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_egprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:977:               tbf->m_dl_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_gprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:1475:      ul_tbf->m_ctrs = rate_ctr_group_alloc(ul_tbf, &tbf_ctrg_desc, 0);
osmo-pcu/src/bts.cpp:226:               m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 1);

We can fix all of these callers and then reconsider returning NULL, but IMO
even into the future, rate counter group indexes are not something worth
failing to provide service for. For future bugs we should keep the automatic
index picking in case of index collisions. We will get an error message barfed
and can fix the issue in our own time, while the application remains completely
usable, and even the rate counters can still be queried (at wrong indexes, but
life is tough).

Neels Hofmeyr cd325efae5 gprs_bssgp: bssgp_fc_in(): fix mem leak on queue overflow
All successful and all error code paths of bssgp_fc_in() free the msgb, except
the code path calling fc_enqueue() when the msg is dropped (due to queue being
full, or failure to allocate).

Callers could theoretically catch the -ENOSPC return value and discard the
msgb. However, in other code paths, a callback's return value is returned,
which is expected to free the msgb, so such callback would have to never return
-ENOSPC when it freed the msgb. Much simpler semantics would be to free the
msgb in every code path, no matter which kind of error occurred.

Who is currently calling bssgp_fc_in and how do they handle the return value?
- bssgp_fc_test.c ignores the return value (and hits a mem leak aka sanitizer
  build failure if the queue is full).
- fc_timer_cb() ignores the return value.
- bssgp_tx_dl_ud() returns the bssgp_fc_in() rc.
  - which is returned by a cascade of functions leading up to being returned,
    for example, by gprs_llgmm_reset(), which is usually called with ignored
    return code.
At this point it is already fairly clear that bssgp_fc_in() should always free
the msgb, since the callers don't seem to distinguish even between error or
success, let alone between -ENOSPC or other errors.

bssgp_fc_test: assert that no msgbs remain unfreed after the tests.
Adjust expected results.

Neels Hofmeyr 0128c78ffe bssgp_fc_test: sanitizer: free msgb context when done
Print remaining msgbs when done, then free the entire tall_msgb_context. To be
able to do that, call msgb_talloc_ctx_init() and use its return value.

A subsequent patch will fix a known mem leak and add assertions for 0b in 1
blocks remaining in the tall_msgb_context.

Neels Hofmeyr 9541a68378 bssgp_fc_test: clarify by outputting ok / failure messages
The test fills up the queue / sends too large PDUs on purpose. Make that
obvious by outputting returned errors in the expected output.

Cosmetic:
- fc_in()'s return value is ignored, hence don't return anything.
- add comment.

Neels Hofmeyr d8e79c7fff gsm0408_test: sanitize: cleanup msgb
Remove initial msgb talloc context creation: if we create a root ctx for msgb
that all msgb are allocated in, we would in a final cleanup discard all msgbs,
i.e. we would not verify that all msgb are cleaned up properly.

If we create the msgb context and *don't* clean it up in the end, the sanitizer
build fails because the context root is not cleaned up.

Easiest is to actually allocate all msgb at NULL ctx, because then any msgb
that aren't cleaned up properly would still linger, while we don't leave a root
ctx that we need to clean up either.

the libraries supposed to be added to *_LDADD or *_LIBADD
while *_LDFLAGS should contain additional libtool linking

libraries into proper automake variable. While at it - also add
libosmocore.la for tests to LDADD since all the tests link against it
anyway.

As rate counters are automatically exposed on the CTRL interface,
we need to make sure they don't contain special characters such as '.'
which are not permitted/supported by CTRL.

In order to be able to run old versions of osmocom programs with
libosmocore versions after this commit, we introduce some special
name mangling:  Any '.' in the names are replaced with ':' during
counter group registration, if valid identifiers can be obtained
this way.
