The down/up SRCU reader testing uses an hrtimer handler to exit the SRCU

Mixing different flavors of RCU readers is forbidden, for example, you
should not use srcu_read_lock() and srcu_read_lock_nmisafe() on the same
srcu_struct structure. There are checks for this, but these checks are
not tested on a regular basis. This commit therefore adds such tests

An ovpn_peer object holds the whole status of a remote peer
(regardless whether it is a server or a client).
This includes status for crypto, tx/rx buffers, napi, etc.
Only support for one peer is introduced (P2P mode).
Multi peer support is introduced with a later patch.
Along with the ovpn_pee
In a multi-peer scenario there are a number of situations when a
specific peer needs to be looked up.
We may want to lookup a peer by:
1. its ID
2. its VPN destination IP
3. its transport IP/port couple
For each of the above, there is a specific routing table referencing all
peers for fast look u

OpenVPN supports configuring a periodic keepalive packet.
message to allow the remote endpoint detect link failures.
This change implements the keepalive sending and timer expiring logic.

Implement support for basic ethtool functionality.
Note that ovpn is a virtual device driver, therefore
various ethtool APIs are just not meaningful and thus
not implemented.

Whenever a peer is deleted, send a notification to userspace so that it
can react accordingly.
This is most important when a peer is deleted due to ping timeout,
because it all happens in kernelspace and thus userspace has no direct
way to learn about it.

IV wrap-around is cryptographically dangerous for a number of ciphers,
therefore kill the key and inform userspace (via netlink) should the
IV space go exhausted.
Userspace has two ways of deciding when the key has to be renewed before
exhausting the IV space:
1) time based approach:

This commit introduces basic netlink support with family
registration/unregistration functionalities and stub pre/post-doit.
More importantly it introduces the YAML uAPI description along
with its auto-generated files:
- include/uapi/linux/ovpn.h
- drivers/net/ovpn/netlink-gen.c
- drivers/net/ovpn
This change introduces the netlink command needed to add, delete and
retrieve/dump known peers. Userspace is expected to use these commands
to handle known peer lifecycles.

When sending an skb over a socket using skb_send_sock_locked(),
it is currently not possible to specify any flag to be set in
msghdr->msg_flags.
However, we may want to pass flags the user may have specified,
like MSG_NOSIGNAL.

With this change ovpn is allowed to communicate to peers also via TCP.
Parsing of incoming messages is implemented through the strparser API.
Note that ovpn redefines sk_prot and sk_socket->ops for the TCP socket
used to communicate with the peer.
For this reason it needs to access inet6_stream_op
Userspace may want to pass the MSG_NOSIGNAL flag to
tcp_sendmsg() in order to avoid generating a SIGPIPE.
To pass this flag down the TCP stack a new skb sending API
accepting a flags argument is introduced.

Packets sent over the ovpn interface are processed and transmitted to the
connected peer, if any.
Implementation is UDP only. TCP will be added by a later patch.
Note: no crypto/encapsulation exists yet. Packets are just captured and
sent.
