ibmvnic: LPM bug fixes

This series of small patches is meant to resolve a number of
bugs, mostly occurring during an ibmvnic driver reset when
recovering from a logical partition migration (LPM).

The first patch ensures that RX buffer pools are properly
activated following an adapter reset by setting the proper
flag in the pool data structure.

The second patch uses netif_tx_disable to stop TX queues when
closing the device during a reset.

Third, fixup a typo that resulted in partial sanitization of
TX/RX descriptor queues following a device reset.

Fourth, remove an ambiguous conditional check that was resulting
in a kernel panic as null RX/TX completion descriptors were being
processed during napi polling while the device is closing.

Finally, fix a condition where the napi polling routine exits
before it has completed its work budget without notifying the
upper network layers. This omission could result in the
napi_disable function sleeping indefinitely under certain conditions.

Fix a kernel panic resulting from data access of a NULL
pointer during device close. The pending_scrq routine is
meant to determine whether there is a valid sub-CRQ message
awaiting processing. When the device is closing, however,
there is a possibility that NULL messages can be processed
because pending_scrq will always return 1 even if there
no valid message in the queue.

It's not clear what this closing state check was originally
meant to accomplish, so just remove it.

As much as we'd like to play well with others, we really aren't
handling the checksums on non-IP protocol packets very well.  This
is easily seen when trying to do TCP over ipv6 - the checksums are
garbage.

Here we restrict the checksum feature flag to just IP traffic so
that we aren't given work we can't yet do.

net: sched: act_tunnel_key: UDP checksums

Currently, the tunnel_key tc action does not set TUNNEL_CSUM, thus
transmitting packets with zero UDP checksum. This is inconsistent with how
we treat non-lwt UDP tunnels where the default is to fill in the UDP
checksum. Non-zero UDP checksum is the better default anyway for various
reasons previously discussed.

Make this configurable for the tunnel_key tc action with the default being
non-zero checksum. Saves a lot of surprises especially with IPv6.

There's currently no way to request (outer) UDP checksum with

action with IPv6 does not work without going through hassles: both sides
have to have udp6zerocsumrx configured on the tunnel interface. This is
obviously not a good solution universally.

It makes more sense to compute the UDP checksum by default even for IPv4.
Just set the default to request the checksum when using act_tunnel_key.

net: kernel TLS

This series adds support for kernel TLS encryption over TCP sockets.
A standard TCP socket is converted to a TLS socket using a setsockopt.
Only symmetric crypto is done in the kernel, as well as TLS record
framing.  The handshake remains in userspace, and the negotiated
cipher keys/iv are provided to the TCP socket.

We implemented support for this API in OpenSSL 1.1.0, the code is
available at https://github.com/Mellanox/tls-openssl/tree/master

It should work with any TLS library with similar modifications,
a test tool using gnutls is here: https://github.com/Mellanox/tls-af_ktls_tool

RFC patch to openssl:
https://mta.openssl.org/pipermail/openssl-dev/2017-June/009384.html

Changes from V2:

* EXPORT_SYMBOL_GPL in patch 1
* Ensure cleanup code always called before sk_stream_kill_queues to
  avoid warnings

Changes from V1:

* EXPORT_SYMBOL GPL in patch 2
* Add link to OpenSSL patch & gnutls example in documentation patch.
* sk_write_pending check was rolled in to wait_for_memory path,
  avoids special case and fixes lock inbalance issue.
* Unify flag handling for sendmsg/sendfile

Changes from RFC V2:

* Generic ULP (upper layer protocol) framework instead of TLS specific
  setsockopts
* Dropped Mellanox hardware patches, will come as separate series.
  Framework will work for both.

RFC V2:

http://www.mail-archive.com/netdev@vger.kernel.org/msg160317.html

Changes from RFC V1:

* Socket based on changing TCP proto_ops instead of crypto framework
* Merged code with Mellanox's hardware tls offload
* Zerocopy sendmsg support added - sendpage/sendfile is no longer
  necessary for zerocopy optimization

RFC V1:

http://www.mail-archive.com/netdev@vger.kernel.org/msg88021.html

* Socket based on crypto userspace API framework, required two
  sockets in userspace, one encrypted, one unencrypted.

Software implementation of transport layer security, implemented using ULP
infrastructure.  tcp proto_ops are replaced with tls equivalents of sendmsg and

Only symmetric crypto is done in the kernel, keys are passed by setsockopt
after the handshake is complete.  All control messages are supported via CMSG
data - the actual symmetric encryption is the same, just the message type needs
to be passed separately.

Add the infrustructure for attaching Upper Layer Protocols (ULPs) over TCP
sockets. Based on a similar infrastructure in tcp_cong.  The idea is that any
ULP can add its own logic by changing the TCP proto_ops structure to its own
methods.

Example usage:

setsockopt(sock, SOL_TCP, TCP_ULP, "tls", sizeof("tls"));

modules will call:
tcp_register_ulp(&tcp_tls_ulp_ops);

to register/unregister their ulp, with an init function and name.

A list of registered ulps will be returned by tcp_get_available_ulp, which is
hooked up to /proc.  Example:

$ cat /proc/sys/net/ipv4/tcp_available_ulp
tls

There is currently no functionality to remove or chain ULPs, but
it should be possible to add these in the future if needed.
