Older kernels (3.x) have ktime_t defined as a union, which means we
can't just treat it as a number and must wrap it inside {}. This still
also works for later kernels which have it typedef'd as an int.

Don't explicitly set the "non forwarding" flag just because an RTCP
stream is being kernelised. The distinction between RTP and RTCP,
together with zero-length outputs setting "non forwarding" automatically
takes care of it.

When using recording via the proc interface, this error indicates that

DTMF requires the "end" event to be sent multiple times, requiring
sequence number adjustments after DTMF injection has finished. Add
support for this to the kernel module.

This combines the REMG_DEL_TARGET method with REMG_GET_STATS. It
retrieves the stats of an existing target, returns them to userspace,
then proceeds to delete the target.

Check all the struct sizes as part of the startup NOOP command, to try

The unified `rtpengine_message` struct has become quite large, and most
fields are not used for most of the messages sent to the kernel module.
Use command-specific structures that only contain the required
information. Adapt the I/O code and the size checks to use the correct
sizes.
Do special handling for GET_*_STATS as these commands do both input and
output at the same time. Copy in only the input portion of the struct.
(Copy-out still copies the entire struct at this point.)

We don't necessarily have a parsed-out RTP header (e.g. when forwarding
T.38) so we can't use the RTP header values to keep stats. Use the
actual datagram size instead.

These are the entries the kernel will try to look for when userspace
tries to use the RTPENGINE support, but the module is called
xt_RTPENGINE so the kernel does not find it and thus cannot autoload
it.
The problem is that we have startup code that sets up iptables rules,
and will fail if the module has not yet been loaded. By adding these
aliases we are no longer concerned about the ordering, and can let the
kernel autoload the modules when they are needed.

The kernel module must take the recording flag (`do_intercept`) into
account when `blackhole` is set, in order to make sure packets are not
dropped before they're passed to the recorder.

Only skip forwarding unknown payload types in the kernel module if
there's reason to skip them, i.e. when we know that certain payload
types must be handled in userspace. Use an explicit flag to signal this
to the kernel module instead of implicitly doing it for anything that is
RTP.

Zero SSRC are technically invalid, but the code accepts them as valid
and therefore sets up things like crypto contexts for zero SSRCs.
Consequently it's possible to have a zero SSRC first in the list of
SSRCs and other valid SSRCs later in the list, which means we can't use
the presence of a non-zero SSRC first in the list as a flag to determine
whether SSRC tracking is in use or not. Use an explicit flag instead.

Despite this code being called from userspace, we must disable
interrupts while having ssrc_stats_lock acquired, as the same lock is

All crypto suites except AEAD have an explicit packet authentication
stage. If authentication fails for a packet, we take some guesses about
a ROC mismatch and see if authentication can succeed with a different
ROC. If a working ROC is found, our tracked ROC is updated and
decryption proceeds.
AEAD doesn't have an explicit authentication stage and authentication is
performed implicitly by the decryption engine, which simply returns a
decryption error if the authentication fails. We must therefore add the
same ROC guessing logic at this step for AEAD.

The main kernel interface has no concept of file position, therefore it
makes no sense to keep the additional overhead of ensuring an atomic
file position. Calling stream_open disables the FMODE_ATOMIC_POS flag
which in turn disables the extra locking for the fpos.

If `strict source` is set, we can now also kernelise RTCP ports. This
will engage the kernel module's source address checking. If the check
fails, the packet is discarded. Otherwise it's passed to user space
as usual.

We need to use the MAKE variable in Makefiles to be able to honor
parallel builds.
While this is of no much consequence here as the kernel module is
composed of a single file, the kbuild system might still be able
to perform other actions in parallel, it still is good form and
makes this future-proof, and copy&paste resistant.
