Contrary to the existing gsm0480_create_ussd_resp(), the new function
only generates the value part of the FACILITY IE, and not the IE
Tag/Length or the 04.08 L3 header. This is needed in the context of
GSUP-encapsulated USSD, as here we don't work with L3 messages, but
only pass on the FACILITY IE value.

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.

Since we ignore "logging level CAT everything" in logging_level_cmd, we
can never run into the case in which we have loglevel==EVERYTHING, so we
can simplify this code and make it esier for later removal of everything
keyword.

The statsd protocol use ':' as seperator between name and value.
It's not allowed to use the seperator in a name. Replace ':' with '.'

Previous logic regarding logging of verification and mangling of

This buffer verifies that all XMAXC fields must be zero before the
entire buffer is considered as silent by osmo_ecu_fr_conceal().

This makes it easy to debug how XMAXC fields are decreased every
iteration in osmo_ecu_fr_conceal().
Change-Id: I678d4be5e0b15b05873b0d3bf5ea5bbee7bef839
As stated in its own documentation, reduce_xmaxcr_all() should only
return true when ALL XMAXC fields return true. However, previous
implementation returned true when at least one of them returned true.
As a result, if any of the sections is silent (for instance because one
of the bursts was lost), the whole frame is silenced, returning a zeroed buffer.

Recent OS#3407 shows that we should verify stderr to catch sanitizer failures.
(They might not always be ignorable like that one.)

Multiplying the uint16_t x by itself seems to default to be calculated in
int32_t range, while it obviously needs uint32_t. This causes sporadic
sanitizer barfs:
Testing integer square-root
utils_test.c:445:18: runtime error: signed integer overflow: 60369 * 60369 cannot be represented in type 'int'
The final result is still correct, because it is in fact interpreted as uint32_t.
Cast to uint32_t to make sure the sanitizer doesn't complain.

Our implementation generates ERROR CTRL messages with ID=error when it
is unable to parse a CMD. However, it doesn't account for them when
trying to receive and parse this kind of message. As a result, it will
return an ERROR message with a different description. This commit fixes
the old behaviour to success at parsing and returning the received
description to the caller.

vty_test: add test against ambiguous cmd causing use-after-free and memory
leaks. Add this test along with the fix, because the new test triggers the
memory use-after-free and leaks, causing build failures.
Add cmd_deopt_with_ctx() to allow passing a specific talloc ctx.
is_cmd_ambiguous(): keep all cmd_deopt() allocations until the function exits.
Add a comment explaining why. Before this, if a command matched an optional
"[arg]" with square brackets, we would keep it in local var 'matched', but we
would free the string it points to at the end of that loop iteration; upon
encountering another match, we would attempt to strcmp against the freed
'matched'. Instead of adding hard-to-read and -verify free/alloc dances to keep
the 'matched' accurately freed/non-freed/..., just keep all cmd_deopt() string
allocated until done.
Needless to say that this should have been implemented on a lower level upon
inventing optional args, but at least this is fixing a program crash.

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
applications to have build failures, as OSMO_ASSERT() now appeared
to be able to return to the call site. Let's inform the compiler
explicitly that there's no return from osmo_panic().
Change-Id: I8adf4c7b0ee6a4581cef8dd4e9f6a1dfde70ee55
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.
