It seems with default flags in_buf was being memzeroed by the compiler.
When compiling with -O0, that's not the case anymore and printf prints

inline keyword is a hint for the compiler to inline the function, but
it's not mandatory. If no static or extern is specified, the definition
is only visible in the current unit but the identifier still has
external linkage.
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.

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.

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,
>phub_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).

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.
Drop all invocations to these two functions found in libosmocore.

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:

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.

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
was encoded in the AUTS. The only way to know this is to provide it as a
separate out-parameter from milenage_gen_vec_auts(), because the SQN.MS from
AUTS stored in umts.sqn is immediately modified non-trivially by
milenage_gen_vec(). Add sqn_ms to struct osmo_sub_auth_data to retain SQN.MS
even after a vector was generated.
Use this to print out SQN.MS for 'osmo-auc-gen -3 -A'.

During UMTS AKA, the caller typically indicates which IND slot the next used
SQN should belong to. Without this option, osmo-auc-gen will always produce SQN
from IND-slot 0. Add --ind option.

Most USIM out there seem to use IND-length = 5 bits, so do sysmousim-sjs1.
Currently from initialization we are using an IND length of zero in
osmo-auc-gen, which produces confusing SQN results after AUTS:
Where want SQN to be incremented to the next IND array, usually +32, an IND-len
of 0 makes for only +1.
As result, the osmo-auc-gen_test.sh produces SQN 32 instead of 24 after
receiving SQN.MS = 23 from AUTS: adjust test expectations.

osmo-auc-gen tries to be helpful by deriving the SQN.MS from the SQN that

In a string like

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.
There is no any (performance or size) benefit from 'inline' keyword
in this particular file, so let's replace one by 'static'.
