The EIP-97 is a packet processing module found on the ESPRESSObin. This
commit adds a crypto(9) driver for the crypto and hash engine in this
device. An initial skeleton driver that could attach and submit
requests was written by loos and others at Netgate, and the driver was
finished by me.
Support for separate AAD and output buffers will be added in a separate
commit, to simplify merging to stable/12 (where those features don't
exist).

without "options SCTP" supports dynamic loading of the SCTP stack.
Currently sctp.ko cannot be unloaded since some prerequisite teardown
logic is not yet implemented. Attempts to unload the module will return

IPSEC_SUPPORT can currently only cope with either IPSEC || IPSEC_SUPPORT,
not both. Refrain from building if IPSEC is set, as the resulting module
won't be able to load anyways if it's built into the kernel.
KERN_OPTS is safe here; for tied modules, it will reflect the kernel
configuration. For untied modules, it will defer to whatever is set in
^/sys/conf/config.mk, which doesn't set IPSEC for modules. The latter
situation has some risk to it for uncommon scenarios, but such is the life
of untied kernel modules.

Honoring the kernel-supplied opt_ipsec.h in r361632 causes builds of
ipsec modules to fail if the kernel doesn't include IPSEC_SUPPORT.
However, the module can never be loaded into such a kernel, so only
build the modules if the kernel includes IPSEC_SUPPORT.

The ice(4) driver is the driver for the Intel E8xx series Ethernet
controllers; currently with codenames Columbiaville and
Columbia Park.
These new controllers support 100G speeds, as well as introducing
more queues, better virtualization support, and more offload
capabilities. Future work will enable virtual functions (like
in ixl(4)) and the other functionality outlined above.
For full functionality, the kernel should be compiled with
"device ice_ddp" like in the amd64 NOTES file, and/or
ice_ddp_load="YES" should be added to /boot/loader.conf so that
the DDP package file included in this commit can be downloaded
to the adapter. Otherwise, the adapter will fall back to a single
queue mode with limited functionality.
A man page for this driver will be forthcoming.

This NFS lock device driver was replaced by the kernel NLM around FreeBSD7 and
has not normally been used since then.
To use it, the kernel had to be built without "options NFSLOCKD" and
the nfslockd.ko had to be deleted as well.
Since it uses Giant and is no longer used, this patch removes it.
With this device driver removed, there is now a lot of unused code
in the userland rpc.lockd. That will be removed on a future commit.

Port aacraid driver to big-endian (BE) hosts.
The immediate goal of this change is to make it possible to use the
aacraid driver on PowerPC64 machines that have Adaptec Series 8 SAS
controllers.
Adapters supported by this driver expect FIB contents in little-endian
(LE) byte order. All FIBs have a fixed header part as well as a data
part that depends on the command being issued to the controller.
In this way, on BE hosts, the FIB header and all FIB data structures
used in aacraid.c and aacraid_cam.c need to be converted to LE before
being sent to the adapter and converted to BE when coming from it.
The functions to convert each struct are on aacraid_endian.c.
For little-endian (LE) targets, they are macros that expand
to nothing.
In some cases, when only a few fields of a large structure are used,
the fields are converted inline, by the code using them.

Add a very basic NVRAM driver for OPAL which can be used by the IBM
powerpc-utils nvram utility, not to be confused with the base nvram utility,
which only operates on powermac_nvram.
The IBM utility handles all partitions itself, treating the nvram device as
a plain store.
An alternative would be to manage partitions in the kernel, and augment the
base nvram utility to deal with different backing stores, but that
complicates the driver significantly. Instead, present the same interface
IBM's utlity expects, and we get the usage for free.

KTLS adds support for in-kernel framing and encryption of Transport
Layer Security (1.0-1.2) data on TCP sockets. KTLS only supports
offload of TLS for transmitted data. Key negotation must still be
performed in userland. Once completed, transmit session keys for a
connection are provided to the kernel via a new TCP_TXTLS_ENABLE
socket option. All subsequent data transmitted on the socket is
placed into TLS frames and encrypted using the supplied keys.
Any data written to a KTLS-enabled socket via write(2), aio_write(2),
or sendfile(2) is assumed to be application data and is encoded in TLS
frames with an application data type. Individual records can be sent
with a custom type (e.g. handshake messages) via sendmsg(2) with a new
control message (TLS_SET_RECORD_TYPE) specifying the record type.
At present, rekeying is not supported though the in-kernel framework
should support rekeying.
KTLS makes use of the recently added unmapped mbufs to store TLS
frames in the socket buffer. Each TLS frame is described by a single
ext_pgs mbuf. The ext_pgs structure contains the header of the TLS
record (and trailer for encrypted records) as well as references to
the associated TLS session.
KTLS supports two primary methods of encrypting TLS frames: software
TLS and ifnet TLS.
Software TLS marks mbufs holding socket data as not ready via
M_NOTREADY similar to sendfile(2) when TLS framing information is
added to an unmapped mbuf in ktls_frame(). ktls_enqueue() is then
called to schedule TLS frames for encryption. In the case of
sendfile_iodone() calls ktls_enqueue() instead of pru_ready() leaving
the mbufs marked M_NOTREADY until encryption is completed. For other
writes (vn_sendfile when pages are available, write(2), etc.), the
PRUS_NOTREADY is set when invoking pru_send() along with invoking
ktls_enqueue().
A pool of worker threads (the "KTLS" kernel process) encrypts TLS
frames queued via ktls_enqueue(). Each TLS frame is temporarily
mapped using the direct map and passed to a software encryption
backend to perform the actual encryption.
(Note: The use of PHYS_TO_DMAP could be replaced with sf_bufs if
someone wished to make this work on architectures without a direct
map.)
KTLS supports pluggable software encryption backends. Internally,
Netflix uses proprietary pure-software backends. This commit includes
a simple backend in a new ktls_ocf.ko module that uses the kernel's
OpenCrypto framework to provide AES-GCM encryption of TLS frames. As
a result, software TLS is now a bit of a misnomer as it can make use
of hardware crypto accelerators.
Once software encryption has finished, the TLS frame mbufs are marked
ready via pru_ready(). At this point, the encrypted data appears as
regular payload to the TCP stack stored in unmapped mbufs.
ifnet TLS permits a NIC to offload the TLS encryption and TCP
segmentation. In this mode, a new send tag type (IF_SND_TAG_TYPE_TLS)
is allocated on the interface a socket is routed over and associated
with a TLS session. TLS records for a TLS session using ifnet TLS are
not marked M_NOTREADY but are passed down the stack unencrypted. The
ip_output_send() and ip6_output_send() helper functions that apply
send tags to outbound IP packets verify that the send tag of the TLS
record matches the outbound interface. If so, the packet is tagged
with the TLS send tag and sent to the interface. The NIC device
driver must recognize packets with the TLS send tag and schedule them
for TLS encryption and TCP segmentation. If the the outbound
interface does not match the interface in the TLS send tag, the packet
is dropped. In addition, a task is scheduled to refresh the TLS send
tag for the TLS session. If a new TLS send tag cannot be allocated,
the connection is dropped. If a new TLS send tag is allocated,
however, subsequent packets will be tagged with the correct TLS send
tag. (This latter case has been tested by configuring both ports of a
Chelsio T6 in a lagg and failing over from one port to another. As
the connections migrated to the new port, new TLS send tags were
allocated for the new port and connections resumed without being
dropped.)
ifnet TLS can be enabled and disabled on supported network interfaces
via new '[-]txtls[46]' options to ifconfig(8). ifnet TLS is supported
across both vlan devices and lagg interfaces using failover, lacp with
flowid enabled, or lacp with flowid enabled.
Applications may request the current KTLS mode of a connection via a
new TCP_TXTLS_MODE socket option. They can also use this socket
option to toggle between software and ifnet TLS modes.
In addition, a testing tool is available in tools/tools/switch_tls.
This is modeled on tcpdrop and uses similar syntax. However, instead
of dropping connections, -s is used to force KTLS connections to
switch to software TLS and -i is used to switch to ifnet TLS.
Various sysctls and counters are available under the kern.ipc.tls
sysctl node. The kern.ipc.tls.enable node must be set to true to
enable KTLS (it is off by default). The use of unmapped mbufs must
also be enabled via kern.ipc.mb_use_ext_pgs to enable KTLS.
KTLS is enabled via the KERN_TLS kernel option.
This patch is the culmination of years of work by several folks
including Scott Long and Randall Stewart for the original design and
implementation; Drew Gallatin for several optimizations including the
use of ext_pgs mbufs, the M_NOTREADY mechanism for TLS records
awaiting software encryption, and pluggable software crypto backends;
and John Baldwin for modifications to support hardware TLS offload.

The goal of this driver is consolidate information about SuperIO chips
and to provide for peaceful coexistence of drivers that need to access
SuperIO configuration registers.
While SuperIO chips can host various functions most of them are
discoverable and accessible without any knowledge of the SuperIO.
Examples are: keyboard and mouse controllers, UARTs, floppy disk
controllers. SuperIO-s also provide non-standard functions such as
GPIO, watchdog timers and hardware monitoring. Such functions do
require drivers with a knowledge of a specific SuperIO.
At this time the driver supports a number of ITE and Nuvoton (fka
Winbond) SuperIO chips.
There is a single driver for all devices. So, I have not done the usual
split between the hardware driver and the bus functionality. Although,
superio does act as a bus for devices that represent known non-standard
functions of a SuperIO chip. The bus provides enumeration of child
devices based on the hardcoded knowledge of such functions. The
knowledge as extracted from datasheets and other drivers.
As there is a single driver, I have not defined a kobj interface for it.
So, its interface is currently made of simple functions.
I think that we can the flexibility (and complications) when we actually
need it.
I am planning to convert nctgpio and wbwd to superio bus very soon.
Also, I am working on itwd driver (watchdog in ITE SuperIO-s).
Additionally, there is ithwm driver based on the reverted sensors
import, but I am not sure how to integrate it given that we still lack
any sensors interface.
