The existing code would abort iterating over the list of PCO TLVs
if a TLV of length zero was encountered. However, there's nothing
in the spec that would make a zero-length PCO invalid, so we should
continue to iterate over any PCO TLVs after the zero-length one.
This issue was discovered while writing test cases in
osmo-ttcn3-hacks.git

... this probably didn't show up as 8.8.8.8 is dual-endian. doh!
The address was already in network byte order, but msgb_put_u32 "of
course" expects host byte order, ending up the wrong way in the actual
packets :/

In any case, if we add support for ipv6 in tun_addaddr we will need
tun_setaddr (and also change the API of tun_addaddr to use in46_addr).

SYS_ERR is for logging an error from the (operating) system including
the errno value. For general logging, we have DEBUGP/LOGP. Let's
convert the gtp-kernel logging over. This also fixes the related line
ending mess-up as SYS_ERR adds a LF while LOGP/DEBUGP don't.

When genl_socket_open() succeeds but genl_lookup_family() fails,
we have to clean up the socket that we just opened.
This requires a new version of libgtpnl :/

We have to factor out the "run once" code and make sure to really
only run that once, while the per-device code remains in the
gtp_kernel_init() function.

Whether or not GTP kernel support is enabled is the property of a
given APN, and not a global state variable.

The existing kernel GTP support code inherited from OpenGGSN was overly
simplistic and didn't support multiple GTP devices or user-defined GTP
device names. Let's remove that restriction in this patch

When we branched off osmo-ggsn from the old openggsn code base, the
support for kernel-gtp got temporarily removed. This patch
re-introduces support for handling the GTP-U plane in the Linux kernel
by means of libgtpnl + the kernel GTP-U driver.
This only works for IPv4 at the moment, until the kernel GTP-U code
gains IPv6 support.
Kernel GTP currently also is restricted to a single APN per GSN.

Rather than taking an explicit in_addr, prefix_length and a
string-formatted prefix, let's pass in an in46_prefix and derive
the other representations from it.
Also, don't refer to a no-longer-existing global 'ipup' variable but
add it as a function argument.

This ensures that in case of error, any caller can still safely
call talloc_free() on the blacklist pointerm as free on NULL
is well-defined. With the code prior to this patch we fear
a double-free.

netdev_ip_local_get() is a generalized version of tun_ip_local_get()

* we have to use stataddr, not addr (dynamic)
* we have to multiply the length of the address by 8 to get its bit length
* we can simplify the -1 +1 logic (like dynamic)

Fixes: Coverity CID#174189
The 'struct tun' curently only has an in_addr (v4-only) member to
store the address of the tun device, so let's not attempt to store
an IPv6 address in it.
FIXME: This entire code needs an overhaul. The assumption that there's
only one address, and only either v6 or v4 is broken to begin with.

Commit dda21ed7d4 modified previous calls
to ippool_new() removing the pass of flags to avoid allocating certain
problematic IPs from the pool to MS, such as the network, gateway and
broadcast IPs.
Today I did some unsucessful tests with osmo-ggsn with a pool "ip prefix
dynamic 176.16.222.0/24", and thus IP 176.16.222.0 was being assigned to
the MS. De-capsulated DNS packets were received in the tun interface,
but the Linux system in there was unable to correctly forward the
packets to the gateway interface connected to the Internet. However,
adding a second MS which got 176.16.222.1 had its packets forwarded
correctly.
However, previous implementation relies on flag IPPOOL_NOGATEWAY flag to
blindly blacklist first IP after the network ip (ie, .0 and .1 are
removed), which limits the IP reserved for the tun device to be .1. If a
different IP in the range is assigned, it may cause issues. As a result,
a blacklist is introduced in this commit to dynamically fetch the tun IP
address and exlucde it from the pool of available IPs.

Add support for IPv4 and IPv6 global IPs. Also return the prefix length
of the IP address by using a in46_prefix.

Take the chance this commit is changing test output to also remove use
of IPPOOL_NOGATEWAY which is going to be removed soon, and instead test
IPPOOL_NOBROADCAST.
