To report invalid characters in identifiers, it is desirable to escape any
weird characters. Otherwise we might print stray newlines or control characters
in the log output.
ctrl_test.c already uses a print_escaped() function, which will be replaced by
osmo_escape_str() in a subsequent patch.
control_cmd.c will use osmo_escape_str() to log invalid identifiers.

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.

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.

In many callers of the VTY API, we are lacking the vty_install_default() step
at certain node levels. This creates nodes that lack the 'exit' command, and
hence the only way to exit such a node is to restart the telnet session.
Historically, the VTY looked for missing commands on the immediate parent node,
and hence possibly found the parent's 'exit' command when the local node was
missing it. That is why we so far did not notice the missing default commands.
Furthermore, some callers call install_default() instead of
vty_install_default(). Only vty_install_default() also includes the 'exit' and
'end' commands. There is no reason why there are two sets of default commands.
To end this confusion, to catch all missing 'exit' commands and to prevent this
from re-appearing in the future, simply *always* install all default commands
implicitly when calling install_node().
In cmd_init(), there are some top-level nodes that apparently do not want the
default commands installed. Keep those the way they are, by changing the
invocation to new install_node_bare() ({VIEW,AUTH,AUTH_ENABLE}_NODE).
Make both install_default() and vty_install_default() no-ops so that users of
the API may still call them without harm. Do not yet deprecate yet, which
follows in Icf5d83f641e838cebcccc635a043e94ba352abff.

Use these to enhance the vty_test cfg files and test more diverse situations.
The current VTY code expects a go_parent_cb() to be present, otherwise it will
bump right back to the CONFIG_NODE, which will not work with more than one node
level below the CONFIG_NODE. Hence provide a minimal go_parent_cb().

The recent exit-by-indent patch breaks a VTY case where a node is entered but
directly followed by a sibling or ancestor without listing any child nodes.
Regression introduced by I24cbb3f6de111f2d31110c3c484c066f1153aac9.
An example is a common usage in osmo-bts, where 'phy N' / 'instance N' is a
parent node that is commonly left empty:
phy 0
instance 0
bts 0
band 1800
Before this patch, this case produces the error:
There is no such command.
Error occurred during reading the below line:
bts 0

Add a unit test for empty parent node.
Change-Id: Ia0880a17ae55accb092ae8585cc3a1bec9986891
Note: This will break users' config files if they do not use consistent
indenting. (see below for a definition of "consistent".)
When reading VTY commands from a file, use indenting as means to implicitly
exit child nodes. Do not look for commands in the parent node implicitly.
The VTY so far implies 'exit' commands if a VTY line cannot be parsed on the
current node, but succeeds on the parent node. That is the mechanism by which
our VTY config files do not need 'exit' at the end of each child node.
We've hit problems with this in the following scenarios, which will show
improved user experience after this patch:
*) When both a parent and its child node have commands with identical names:
cs7 instace 0
point-code 1.2.3
sccp-address osmo-msc
point-code 0.0.1
If I put the parent's command below the child, it is still interpreted in the
context of the child node:
cs7 instace 0
sccp-address osmo-msc
point-code 0.0.1
point-code 1.2.3
Though the indenting lets me assume I am setting the cs7 instance's global PC
to 1.2.3, I'm actually overwriting osmo-msc's PC with 1.2.3 and discarding the
0.0.1.
*) When a software change moves a VTY command from a child to a parent. Say
'timezone' moved from 'bts' to 'network' level:
network
timezone 1 2
Say a user still has an old config file with 'timezone' on the child level:
network
bts 0
timezone 1 2
trx 0
The user would expect an error message that 'timezone' is invalid on the 'bts'
level. Instead, the VTY finds the parent node's 'timezone', steps out of 'bts'
to the 'network' level, and instead says that the 'trx' command does not exist.
Format:
Consistent means that two adjacent indenting lines have the exact
same indenting characters for the common length:
Weird mix if you ask me, but correct and consistent:
ROOT
<space>PARENT
<space><tab><space>CHILD
<space><tab><space><tab><tab>GRANDCHILD
<space><tab><space><tab><tab>GRANDCHILD2
<space>SIBLING
Inconsistent:
ROOT
<space>PARENT
<tab><space>CHILD
<space><space><tab>GRANDCHILD
<space><tab><tab>GRANDCHILD2
<tab>SIBLING
Also, when going back to a parent level, the exact same indenting must be used
as before in that node:
Incorrect:
ROOT
<tab>PARENT
<tab><tab><tab>CHILD
<tab><tab>SIBLING
As not really intended side effect, it is also permitted to indent the entire
file starting from the root level. We could guard against it but there's no
harm:
Correct and consistent:
<tab>ROOT
<tab><tab>PARENT
<tab><tab><tab><tab>CHILD
<tab><tab>SIBLING
Implementation:
Track parent nodes state: whenever a command enters a child node, push a parent
node onto an llist to remember the exact indentation characters used for that
level.
As soon as the first line on a child node is parsed, remember this new
indentation (which must have a longer strlen() than its parent level) to apply
to all remaining child siblings and grandchildren.
If the amount of spaces that indent a following VTY command are less than this
expected indentation, call vty_go_parent() until it matches up.
At any level, if the common length of indentation characters mismatch, abort
parsing in error.
Transitions to child node are spread across VTY implementations and are hard to
change. But transitions to the parent node are all handled by vty_go_parent().
By popping a parent from the list of parents in vty_go_parent(), we can also
detect that a command has changed the node without changing the parent, hence
it must have stepped into a child node, and we can push a parent frame.
The behavior on the interactive telnet VTY remains unchanged.
Change-Id: I24cbb3f6de111f2d31110c3c484c066f1153aac9
For interactive telnet VTY, remove the implicit move up to the parent node when
a command did not succeed on the current node level.
When reading config files, this behavior was useful to allow skipping explicit
'exit' commands. (A different patch deals with that.)
In the telnet VTY, this behavior was never necessary. Explicit 'exit' commands
can move to the parent node, and typically uninformed users expect to require
that.
On a telnet VTY, counting indents like for reading config files is not an
option: a user will always type from the first column or may paste some leading
spaces without intended meaning.
After this patch, it is thus no longer possible to paste a complete config
across several node levels directly to a telnet session, unless it contains
'exit' commands.

When doing UMTS AKA with AUTS, it can be interesting to know the SQN.MS that

milenage_gen_vec(). Add sqn_ms to struct osmo_sub_auth_data to retain SQN.MS

According to GCC's online docs:
When an inline function is not static, then the compiler must
assume that there may be calls from other source files; since
a global symbol can be defined only once in any program, the
function must not be defined in the other source files, so the
calls therein cannot be integrated. Therefore, a non-static
inline function is always compiled on its own in the usual fashion.

The old osmo_sock_init() function allows only either a bind (for a

Don't use CTRL_TYPE_UNKNOWN as value_string[] terminator, use an explicit, more
obvious { 0, NULL } termination. Set an explicit string for CTRL_TYPE_UNKNOWN.
No other value_string[]s to date have such a "hidden" terminator.
BTW, a { 0, "string" } item is not a terminator, only { 0, NULL } is, so we can
set a string for CTRL_TYPE_UNKNOWN == 0.
Also, having a string value for CTRL_TYPE_UNKNOWN is not harmful because all
code paths explicitly check for the CTRL_TYPE_*s that are valid.
Adjust the test expectation.
From the ctrl_type_vals enum, remove the = 0, because it is implicitly 0
anyway.
One motivation to press this fixup: I am trying to add a script that checks
whether all value_string[]s are terminated to our jenkins jobs, and to find
that this one is terminated, it would need to interpret the CTRL_TYPE_UNKNOWN
constant, which would make things far more complex. At this point, all of the
value_string[]s have an explicit termination, and I would like to enforce this
from now on -- for readable code and to not spend more time on the validator.
The patch adding ctrl_type_vals (Icd4e96dd9f00876cb70b43cfcf42ab4f10311b28) was
accepted by another reviewer before I could reconfirm my -1, so this is a fixup
to enable the termination checking script patches.

Change-Id: Id6947899ff7b1c82b939f969e163e51ce282bce2
So far we incremented SQN by 1, which doesn't match the procedures described in
3GPP TS 33.102. An IND (index) denotes a non-significant part of SQN, and the
significant SEQ part needs to be incremented.
In OsmoHLR we furthermore want to use the "exception" suggested in annex C.3.4,
so that each HLR's client has a fixed IND index. In other words, we will not
assign IND cyclically, but keep IND unchanged per auth vector consumer.
Add 'ind_bitlen' and 'ind' to the osmo_sub_auth_data.u.umts structure and
increment SQN accordingly.
Add a comment explaining the details.
Because 'ind_bitlen' is still passed as zero, the milenage_test does not change
its behavior, which is a feature I want to clearly show in this patch. The test
will be expanded for the newly implemented SQN scheme in a subsequent patch.
Adjust osmo-auc-gen.c to still show the right SQN and SQN.MS -- because it is
passing ind_bitlen == 0, osmo-auc-gen can rely on single increments and know
SQN.MS is sqn - 1. Note that osmo-auc-gen_test output remains unchanged.

Prepare for the implementation of splitting SQN increments in SEQ and an IND
part; particularly to clearly show where the changes in auth/milenage_test's
expectations originate.
Rationale: the source of UMTS auth vectors, for us usually OsmoHLR, typically
stores the last used SQN, not the next one to be used. Particularly with the
upcoming fix of the SQN scheme, this change is important: the next SQN will
depend on which entity asks for it, because each auth consumer may have a
particular slot in the IND part of SQN. It does not make sense to store the
next SQN, because we will not know which consumer that will be for.
The milenage_test has always calculated a tuple for SQN == 34. To account for
the increment now happening before calculating a tuple, lower the test_aud->sqn
by one to 0x21 == 33, so that it is still calculating for SQN == 34.
Because we are no longer incrementing SQN after the tuple is generated,
milenage_test's expected output after doing an AUTS resync to 31 changes to the
next SQN = 32, the SQN used for the generated tuple.
(BTW, a subsequent patch will illustrate AUTS in detail.)
osmo-auc-gen now needs to pass the user requested SQN less one, because the SQN
will be incremented befor generating the auth vector. Also the SQN remains the
same after generating, so SQN output needs less decrementing. Note that the
expected output for osmo-auc-gen_test remains unchanged, hence the same input
arguments (particularly -s <sqn> and -A <auts>) still produce the same results.
Note: osmo-hlr regression tests will require adjustments when this patch is
merged, because it must now pass desired_sqn - 1 instead of just desired_sqn.

Upcoming patches will change the way SQN are incremented. Change the SQN
related output by osmo-auc-gen so that it also makes sense after these changes,
and so that its output is proven to remain unchanged for the same arguments:
Always show the SQN used for vector generation when a UMTS vector was generated.
Don't show the next SQN, it will not make sense anymore (see later patches).
The adjustments of expected output of osmo-auc-gen_test illustrates how the
output changes.

Add test for osmo-auc-gen invocations to ensure stability across upcoming SQN

The test comprises of a shell script that invokes the osmo-auc-gen binary with
various milenage parameters, of which the stdout/stderr are verified.
More osmo-auc-gen invocations could be added, but my main focus is on the SEQ
changes. Instead of manually testing that it still works for each SQN patch, I
want this test to do it for me.

In the milenage_test, the console output printed "SEQ.MS = 33", but 33 is
a) the SQN, not SEQ;
b) the SQN *after* the next auth generation, i.e. SQN.MS would have been 31.
While at it also use the proper PRIu64 from inttypes.h to output the sqn value.
This prepares for upcoming sparation of SQN incrementing by SEQ and IND,
particularly to clearly show where the changes in auth/milenage_test's
expectations originate.

GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same
procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS
to our osmo_auth_gen_vec_auts() API.
According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14
bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2
and AUTS being the V = 14.
It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But
writing 16 bytes to a GSUP struct is a potential problem when passing in a 14
byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer.
The API implies the length, so far to be 16, so passing in a 14 byte buffer to
GSUP would require copying to a larger buffer first.
Fix this by using a length of 14 for AUTS everywhere instead.
This constitues an ABI breakage, we may handle it as a "fix before an official
release", otherwise we need a version bump.
The OAP protocol document has also been updated, needs an update in the
osmo-gsm-manuals as well.

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.

Numerous issues caused sim_test to be attempted even though libosmosim was not
built:
In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported.
Furthermore in configure.ac, no value 'yes'/'no' was assigned to the
ENABLE_PCSC variable, only to the enable_pcsc value.
In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have
no effect, regardless (not even when using a variable that should be defined
accurately).
So fix with these steps, similarly to how we do it in openbsc:
In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'.
Export the same using AC_SUBST().
Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add
atlocal to AC_OUTPUT and distclean).
Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to
indicate skipping the test if enable_sim_test isn't 'yes'.

The osmo_hexdump of the output in sh_chk() omitted the last byte of the
returned bytes from the osmo_nibble_shift_*() functions.
Determine the number of bytes from nibbles divided by two plus one for any odd
nibble number. Output this number of bytes of output data.
Memset the output buffer to get well-defined bytes for unwritten places.
Also assert that we have enough buffer length for all nibbles.

Previously while testing osmo_nibble_shift_left_unal() following error was
triggered by AddressSanitizer upon offs == 12 and the last sh_chk line, i.e.
shift left of 12 nibbles from in2:

Address 0xbff5b5b6 is located at offset 38 in frame <main> of T0's stack:
This frame has 3 object(s):
[32, 38) 'in2'
[96, 104) 'out'
[160, 168) 'in1'
The reason is incorrect range in test cycle. Fix it and adjust test
output accordingly.

Use osmo_gettimeofday_override* to decouple the timer test from real time. No
longer call osmo_select_main(), since select() actually waits for real time.
This reduces the timer_test to the osmo_timer_* logic and excludes the real
time and osmo_timers_nearest() accuracy testing with actual waiting involved.
This may be seen as a loss, but is more fit for a test suite.
The main point here is to get deterministic results in jenkins, so that we
don't have to retrigger jobs based on timing failures; added bonus is that the
test runs much faster now.

When a timer was late, show the timing details.
Also count whether timers fired early, for completeness' sake.

The timer_test schedules timers and records the desired stop time. Also store
the usec value of the desired stop time, because scheduling at e.g. sec N usec
999999 but recording sec N usec 0, and then receiving a timer at sec N+1 usec 0
is only 1 usec late, but records as 1000000 usecs late. This might have been
the main cause of the timer test not working well on the osmocom build server.

Add src/gsm/libosmogsm.la explicitly to some test linkages, because otherwise
the linker would pick the libosmogsm already installed on the system instead of
the one that was just built in the source tree.
I noticed because a libosmogsm needing some more symbols from libosmocodec was
still installed, while the patch that cause it was already removed. Thus I
caught all(?) test binaries that linked libosmogsm from $PREFIX.

Keith of Rhizomatica has an issue of a unrejected interrogateSS.
Start with just decoding the message and printing the empty test
and the code.
What is kind of missing is the classification between invoke,
returnResult and returnResultLast that we need to add in the
long run.

Corresponding test code include both official test vectors from the
specs and data from over-the-air tests.
This obsoletes libosmo-crypt-a53 as it was last missing piece
unimplemented in libosmogsm.

Check if library actually support Milenage, COMP128 v2 and v3 algorithms
instead of just printing enum values or nothing.
