Previously it was only possible to enable target mode for these drivers
by rebuilding the kernel with AHC_TMODE_ENABLE or AHD_TMODE_ENABLE and a
bitmask of which units to statically enable for target mode.
There is no space-savings in the driver by not having AHC_TMODE_ENABLE
set, so in addition to the compile time option lets also introduce some
tunables:
hint.ahc.<unit>.tmode_enable=0/1
hint.ahd.<unit>.tmode_enable=0/1
For compatibility the old behavior is retained, but it can be overridden
with tunables

This is the server (target in SCSI terms) for NVMe over Fabrics.
Userland is responsible for accepting a new queue pair and receiving
the initial Connect command before handing the queue pair off via an
ioctl to this CTL frontend.
This frontend exposes CTL LUNs as NVMe namespaces to remote hosts.
Users can ask LUNS to CTL that can be shared via either iSCSI or
NVMeoF.

This is the client (initiator in SCSI terms) for NVMe over Fabrics.
Userland is responsible for creating a set of queue pairs and then
handing them off via an ioctl to this driver, e.g. via the 'connect'
command from nvmecontrol(8). An nvmeX new-bus device is created
at the top-level to represent the remote controller similar to PCI
nvmeX devices for PCI-express controllers.
As with nvme(4), namespace devices named /dev/nvmeXnsY are created and
pass through commands can be submitted to either the namespace devices
or the controller device. For example, 'nvmecontrol identify nvmeX'
works for a remote Fabrics controller the same as for a PCI-express
controller.
nvmf exports remote namespaces via nda(4) devices using the new NVMF
CAM transport. nvmf does not support nvd(4), only nda(4).

Structurally this is very similar to the TCP transport for iSCSI
(icl_soft.c). One key difference is that NVMeoF transports use a more
abstract interface working with NVMe commands rather than transport
PDUs. Thus, the data transfer for a given command is managed entirely
in the transport backend.
Similar to icl_soft.c, separate kthreads are used to handle transmit
and receive for each queue pair. On the transmit side, when a capsule
is transmitted by an upper layer, it is placed on a queue for
processing by the transmit thread. The transmit thread converts
command response capsules into suitable TCP PDUs where each PDU is
described by an mbuf chain that is then queued to the backing socket's
send buffer. Command capsules can embed data along with the NVMe
command.
On the receive side, a socket upcall notifies the receive kthread when
more data arrives. Once enough data has arrived for a PDU, the PDU is
handled synchronously in the kthread. PDUs such as R2T or data
related PDUs are handled internally, with callbacks invoked if a data
transfer encounters an error, or once the data transfer has completed.
Received capsule PDUs invoke the upper layer's capsule_received
callback.
struct nvmf_tcp_command_buffer manages a TCP command buffer for data
transfers that do not use in-capsule-data as described in the NVMeoF
spec. Data related PDUs such as R2T, C2H, and H2C are associated with
a command buffer except in the case of the send_controller_data
transport method which simply constructs one or more C2H PDUs from the
caller's mbuf chain.

libnvmf provides APIs for transmitting and receiving Command and
Response capsules along with data associated with NVMe commands.
Capsules are represented by 'struct nvmf_capsule' objects.
Capsules are transmitted and received on queue pairs represented by
'struct nvmf_qpair' objects.
Queue pairs belong to an association represented by a 'struct
nvmf_association' object.
libnvmf provides additional helper APIs to assist with constructing
command capsules for a host, response capsules for a controller,
connecting queue pairs to a remote controller and optionally
offloading connected queues to an in-kernel host, accepting queue pair
connections from remote hosts and optionally offloading connected
queues to an in-kernel controller, constructing controller data
structures for local controllers, etc.
libnvmf also includes an internal transport abstraction as well as an
implementation of a userspace TCP transport.
libnvmf is primarily intended for ease of use and low-traffic use cases
such as establishing connections that are handed off to the kernel.
As such, it uses a simple API built on blocking I/O.
For a host, a consumer first populates an 'struct
nvmf_association_params' with a set of parameters shared by all queue
pairs for a single association such as whether or not to use SQ flow
control and header and data digests and creates a 'struct
nvmf_association' object. The consumer is responsible for
establishing a TCP socket for each queue pair. This socket is
included in the 'struct nvmf_qpair_params' passed to 'nvmf_connect' to
complete transport-specific negotiation, send a Fabrics Connect
command, and wait for the Connect reply. Upon success, a new 'struct
nvmf_qpair' object is returned. This queue pair can then be used to
send and receive capsules. A command capsule is allocated, populated
with an SQE and optional data buffer, and transmitted via
nvmf_host_transmit_command. The consumer can then wait for a reply
via nvmf_host_wait_for_response. The library also provides some
wrapper functions such as nvmf_read_property and nvmf_write_property
which send a command and wait for a response synchronously.
For a controller, a consumer uses a single association for a set of
incoming connections. A consumer can choose to use multiple
associations (e.g. a separate association for connections to a
discovery controller listening on a different port than I/O
controllers). The consumer is responsible for accepting TCP sockets
directly, but once a socket has been accepted it is passed to
nvmf_accept to perform transport-specific negotiation and wait for the
Connect command. Similar to nvmf_connect, nvmf_accept returns a newly
construct nvmf_qpair. However, in contrast to nvmf_connect,
nvmf_accept does not complete the Fabrics negotiation. The consumer
must explicitly send a response capsule before waiting for additional
command capsules to arrive. In particular, in the kernel offload
case, the Connect command and data are provided to the kernel
controller and the Connect response capsule is sent by the kernel once
it is ready to handle the new queue pair.
For userspace controller command handling, the consumer uses
nvmf_controller_receive_capsule to wait for a command capsule.
nvmf_receive_controller_data is used to retrieve any data from a
command (e.g. the data for a WRITE command). It can be called
multiple times to split the data transfer into smaller sizes.
nvmf_send_controller_data is used to send data to a remote host in
response to a command. It also sends a response capsule indicating
success, or an error if an internal error occurs. nvmf_send_response
is used to send a response without associated data. There are also
several convenience wrappers such as nvmf_send_success and
nvmf_send_generic_error.

This is done by having msix_disable default to 2, which means

When in netmap (emulated) mode, wireguard interfaces prepend or strip a
dummy ethernet header when interfacing with netmap. The netmap
application thus sees unencrypted, de-encapsulated frames with a fixed

In this mode, netmap hooks the if_input and if_transmit routines of the
ifnet. Packets from the host TX ring are handled by wg_if_input(),
which simply hands them to the netisr layer; packets which would
otherwise be tunneled are intercepted in wg_output() and placed in the
host RX ring.
The "physical" TX ring is processed by wg_transmit(), which behaves
identically to wg_output() when netmap is not enabled, and packets
appear in the "physical" RX ring by hooking wg_deliver_in().

Hot-unplugging a sound device, such as a USB sound card, whilst being

The timeout mechanism works by calling chn_sleep() in chn_read() and

using cv_timedwait_sig(). Since chn_sleep() sets the CHN_F_SLEEPING flag
while waiting for cv_timedwait_sig() to return, we can test this flag in
pcm_unregister() (called during detach) and wakeup the sleeping

The trim is not started if the pool is degraded (which matches the
