5b27db6268 lib/nvmf: Check if I/O qpair is on the same listener as admin qpair
We will have ANA state per listener and per subsystem. On the other hand,
NVMe specification defines ANA state per controller.

However, it is possible that I/O qpair and admin qpair are different
listeners on a single controller.

Let's check if I/O qpair is on the same listener as admin qpair if
ANA reporting is enabled.

The case that I/O qpair is on a different listener from admin qpair
is not usual and so the purpose of this check is just to guard SPDK
from any unexpected behavior.

6f2265734d lib/nvmf: Optionalize ANA reporting feature
After supporting ANA reporting by default, Linux kernel 5.3 reported
error when parsing NVMe ANA log. The newer kernel fixed the issue
but we should optionalize ANA reporting feature to avoid error for
Linux kernel 5.3 or before.

Add a bool variable ana_reporting to struct spdk_nvmf_subsystem
and disable ANA reporting and initialization of related variables
if it is false. We can expose MNAN (Maximum Number of Allowed
Namespaces) even if ANA reporting is disabled. But MNAN is not
required if ANA reporting is disabled. So do not set MNAN if it is
false too.

Add a public API spdk_nvmf_subsystem_set_ana_reporting() to set
ana_reporting by the nvmf_create_subssytem RPC.

The next patch will add ana_reporting to nvmf_create_subsystem RPC.

Add an new RPC, nvmf_subsystem_get_controllers to retrieve the list

One of the main use cases will be to get identification information

Pause and resume the subsystem to access the controllers safely.

One subtle issue remains. The JSON RPC returns success even if
resuming the subsystem fails. Write FIXME explicitly to address this.

43ad7febb2 lib/nvmf: Fixes stuck subsystem RPC
A subsystem RPC is not transitioned to a paused state when there
are ios outstanding (tracked by subsystem poll group).

In general AERs, are not tracked as outstanding IOs. However,
there are 3 paths in nvmf_ctrlr_async_event_request which do not
adjust the outstanding io count.
If we get into any of these 3 paths, the subsystem pause can hang
forever.

The issue was reproduced with hot plug stress testing under load.
We can get into the second path (SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE)
under these circumstances:
- An AER completion is sent to the initiator due to a namespace change
(e.g. hot remove/add)
- In this case, type is set to SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE
- The initiator sends a new AER admin command, hitting the second path
where we return without adjusting the outstanding ios.

Fixes: 1552

85ff3fcea6 rdma: Do not use the poller to handle the qpair exiting.
Generally, this patch did the following work:

Remove the destruct poller. I think that we do not need this,
the destruct poller is specially for Softwaare RoCE case.
Since SoftRoCE will not have IBV_EVENT_QP_LAST_WQE_REACHED event,
we will not wait the last_wqe_reached flag when srq is enabled.
So we can avoid using the poller.

And the purpose of this patch is to solve the coredump issue.
For example, if we run rdma local test such as, e.g.,

test/nvmf/host/bdevperf.sh --transport=rdma

The coredump reason: the qpair is freed twice. Because for RDMA transport,
we do not really remove the qpair from the group if the upper layer
does it.

The first time is called by nvmf_rdma_destroy_drained_qpair in nvmf_rdma_poller_poll,
and the second time is called by nvmf_rdma_qpair_reject_connection in
in nvme_rdma_close_qpair. Since nvme_rdma_close_qpair will always called,
so we need make sure that the qpair will be close after calling this function.
Otherwise we will have the double free qpair. So our approach here is add a flag
("to_close")in rqpair structure and make sure the rqpair be freed after the
"to_close" is set  nvme_rdma_close_qpair

d156d2f771 lib/nvmf: don't free ctrlr->qpair_mask early.
There are 2 messages passed between when
_nvmf_ctrlr_free_from_qpair is executed and when
nvmf_ctrlr_destruct is executed. That leaves time
when the controller->qpair_mask is not a valid
pointer, but it is still in the subsystem
controllers list.

The purpose of this patch is to close that hole.

It is part of a larger series aimed at cleaning up
the controller destruct path.

Since rqpair->qpair.group is set to NULL when we remove the

This patch adds a pointer to io_chaneel to spdk_nvmf_rdma_qpair
structure and a function to handle poll_group_remove transport
operation. In this function we get io_channel from nvmf_tgt,
this channel will be used to get a thread for sending
async event notification. This also guarantees that the thread
will be alive while we are destroying qpair.

72eedc578d nvmf/tcp: Abort request whose CID matches if it is pending
If the request is queued and is not in completing, we can abort
it safely.

If the state of the request is NEED_BUFFERING, the request is
queued to both tqpair->group->group.pending_buf_queue and
the queue per state.

If the state is AWAITING_R2T_ACK, the request is queued to the
queue per state.

Dequeueing from the queue per state is done in
nvmf_tcp_req_set_state(). Hence explicit dequeuing only when the
state of the request is NEED_BUFFERING.

Most abort operation is common between two cases. We can use fallthrough
in switch-case but factor out the common operation into a helper
function nvmf_tcp_req_set_abort_status() instead because we may use
the helper function in future and using helper function is easier to
read than fallthrough.

604b4503c4 lib/nvmf: Add nvmf_transport_qpair_abort_request()
State machine is different among NVMe-oF transports and is
encapsulated to the transport neutral NVMe-oF controller and
NVMe-oF qpair.

To implement abort operation for each NVMe-oF transport,
add a function pointer qpair_abort_request to struct spdk_nvmf_transport_ops
and a stub nvmf_transport_qpair_abort_request() to encapsulate
which transport is used.

The following patches will implement qpair_abort_request for each
transport. Each qpair_abort_request() is responsible to call
spdk_nvmf_request_complete() for the abort request.

and it will be consistent with the logic in the same

db96437e42 lib/nvmf: Include redirection into spdk_nvmf_request_complete()
Some cases need to redirect spdk_nvmf_request_complete() to the
thread pointed by qpair->group->thread. Abort command will be
included such cases but abort command is executed in the different
file ctrlr_bdev.c. For the convenience, change spdk_nvmf_request_complete()
to include the redirection and extract the core operation of
spdk_nvmf_request_complete() into a private function
_nvmf_request_complete(). In ctrlr.c, call _nvmf_request_complete()
for non-redirected cases.

Besides, locate the definition of _nvmf_request_complete() under the
definition of  spdk_nvmf_request_complete() in a file to trick the format
check tool to avoid false positive, and fix a spell error together.

1551197db5 rpc: Deprecate max_qpairs_per_ctrlr parameter
This parameter describes the number of admin and IO
qpairs while admin qpair always exists and should not
be configured explicitly.
Introduce a new parameter `max_io_qpairs_per_ctrlr`
which configures the number of IO qpairs.
Internal structure of NVMF transport is not changed,
both RPC parameters configure the same nvmf transport parameter.

Deprecate max_qpairs_per_ctrlr in spdkcli as well

Side change: update dif_insert_or_strip description -
it can be used by TCP and RDMA transports

Config files parsing is not changed since it is deprecated

ba1d0d7220 nvmf: set sgroup for spdk_nvmf_request_exec_fabrics() API
When using spdk_nvmf_request_exec_fabrics() to connect one IO
queue, the qpair->ctrlr is null before this function, and the
qpair->ctrlr will be set to associate controller after the

a4340e4501 Set low watermark in NVMe/TCP target to a more appropriate value.
In SPDK NVMe/TCP target, when initializing the socket, the low
watermark is set to sizeof(struct spdk_nvme_tcp_common_pdu_hdr),
which is 24 bytes. In our testing, some times there might be very
small data packet (as small as 16 bytes) be sent to wire. After
this, if there is no more data sent to the same socket, this small
data packet won’t be received by NVMe/TCP controller qpair thread
because the size hasn’t reached the low watermark. Because of this,
the qpair thread is waiting for more data come in and the initiator
is waiting for the IO request to be completed. Hence the delay
happens.

As the minimum data that allows target to determine the PDU type is
sizeof(struct spdk_nvme_tcp_common_pdu_hdr), which is 8 bytes, we
changed low watermark setting as below. With the change, the problem
was gone immediately.

Purpose: To set the priority of the NVMe-oF connection especially

For example, the previous example can be:

trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420

With the change, it could be:

trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420 priority:2

The priority is optional. We try to change
spdk_nvme_transport_id but not in spdk_nvme_ctrlr_opts since
the opts in spdk_nvme_ctrlr_opts will reflect in every nvme ctrlr,
this is short of flexibility.

9d39be44c5 nvmf/ctrlr: remove assert for qpair state.
Historically, we have immediately called the qpair
fini function directly from _spdk_nvmf_qpair_destroy.

However, to fix a race with initiators where we can get
a duplicate QID from the initiator, we will have to clear
the QID bit before calling qpair_fini. Clearing the QID bit
must be done on the controller thread, so we have to pass at
least two messages between calling _spdk_nvmf_qpair_destroy
and qpair_fini. This leaves a gap where we can poll the poll group
and reap completions for the qpair before we call qpair_fini and drain
all of the requests related with the qpair.

Currently SPDK rejects Connect command when subsystem is not active.
This change allows to queue Connect command and execute it when
the subsystem goes back to active state. To queue the command we
should know subsystem_poll_group, in current implementation
this poll_group is known only when controller is already created.
To get the poll_group for Connect command we can retrive subsystem
subnqn, find subsystem and get poll_group by subsystem->id.

Increment subsystem_poll_group->io_outstanding even for Connect
cmd in order to prevent subsystem change state during the
connection process. Update spdk_nvmf_request_complete -
decrement io_outstanding for Connect cmd.

2fa51eeb46 lib/nvmf: Make spdk_nvmf_poll_group_destroy() asynchronous
The next patch will create poll group threads dynamically for
NVMe-oF target, and will need to wait for completion of poll group and
I/O channel destroy. This is a preparation for the next patch.

Add callback function and its argument to spdk_nvmf_poll_group_destroy(),
and to struct spdk_nvmf_poll_group, respectively.

The callback has not only cb_arg but also status as its parameters even
if the next patch always sets the status to zero. The reason is to follow
spdk_nvmf_tgt_destroy's callback and to process any case that the status
is nonzero in future.

spdk_nvmf_poll_group_destroy() sets the passed callback to the passed
poll group.

Then spdk_nvmf_tgt_destroy_poll_group() calls the held callback in the
end.

This change will ensure all pollers are being unregistered and
all I/O channels are being released.

f0ca01e102 lib/nvmf: properly validate fuse command fields.
The fuse command value is a two byte value, but we were only checking to
see if the fuse value was equal to SPDK_NVME_CMD_FUSE_FIRST or
SPDK_NVME_CMD_FUSE_SECOND in spdk_nvmf_ctrlr_process_io_fused_cmd. If a
haywire initiator sent a command with a fused value equal to
SPDK_NVME_CMD_FUSE_MASK, that would result in us skipping all checks and
dereferencing a null pointer in
spdk_nvmf_bdev_ctrlr_compare_and_write_cmd.

To fix this, add an extra condition to validate the cuse field.

f84c916c41 nvmf/tcp: Correctly kick the recv state machine when a request is freed
When a command arrives and no requests are available, the socket
recv state machine sits in the RECV_STATE_AWAIT_REQ state until another
network event occurs. If this I/O was the last one sent, this leaves the
target hung. To fix this, when a request is completed, kick the state
machine to make forward progress.

In practice, this can only occur once the pdu send acknowledgements are
asynchronous relative to arriving commands. That only begins happening
with the use of MSG_ZEROCOPY. When MSG_ZEROCOPY is turned on, it's
possible receive the next PDU in a chain for a command prior to seeing
the acknowledgement that the response that triggered that PDU actually
sent.

48a547fd82 nvmf/tcp: Wait for R2T send ack before processing H2C
Previously, the R2T was sent and if an H2C arrived prior
to seeing the R2T ack, it was processed anyway. Serialize
this process.

In practice, if the H2C arrives with a correctly functioning
initiator, that means the R2T already made it to the initiator.
But because the PDU hasn't been released yet, immediately processing the
PDU requires an extra PDU associated with the request. Basically, making
this change halves the worst-case number of PDUs required per
connection.

In the current sock layer implementations, it's not actually possible
for the R2T send ack to occur after that H2C arrives. But with the
upcoming addition of MSG_ZEROCOPY and other sock implementations, it's
best to fix this now.

a2adca79d9 nvmf/tcp: Set up math to always use 1 R2T per nvme command
With our target design, there's no advantage to sending
multiple R2T PDUs per nvme command. This patch starts by
setting up the math so that at most 1 R2T PDU is required
per request. This can be guaranteed because the maximum
data transfer size (MDTS) is pre-negotiated in NVMe-oF
to a reasonable size at start up.

It then proceeds to simplify all of the logic around mapping
requests to PDUs. It turns out that the mapping is now always
1:1. There are two additional cases where there is no request
object at all but a PDU is still needed - the connection response
and termination request. Put an extra PDU on the queue object
for that purpose.

This is a major simplification.

4dba507224 nvmf/tcp: Simplify qpair resource initialization
The resources allocated to a queue pair do not need to be directly
correlated to the queue size requested by the initiator in NVMe-oF, as
long as enough resources are present. The RDMA transport, for instance,
does complex pooling of the resources behind the scenes when using a
shared receive queue.

Simplify the resource allocation for a TCP qpair to just always allocate
the max allowed queue size right away. This is a configurable parameter,
so system administrators can adjust for their needs. The initiator may
then request a queue size less than or equal to that, which will only be
enforced by queue depth counting and not impact the actual number of
resources allocated on the target.

This change relies on the MaxC2HSize being equal to the Maximum Data
Transfer Size (MDTS) reported. That is the default configuration, but
MDTS is configurable. Changing the MDTS with this patch to a value
larger than 128k will cause the target to break. This is addressed in
the next patch in this series.

2167c68d18 lib/nvmf: nvmf target stops to listen when subsystem is destroyed
There is a spdk_nvmf_tgt_listen() which opens a port for specified
transport (trid) which opens possibility to accept new connections
from initiators. However there is no counterpart of this function
(i.e. spdk_nvmf_tgt_stop_listen()), which would stop listening.
Instead the current code relies on spdk_nvmf_subsystem_destroy()
to stop the listener, which seems to be wrong.

Fixes #1129

3fa2205647 lib/nvmf: custom admin cmd handler
This commit provides the capability to install a
    custom admin command handler for NVMF.
    It can be used to implement or replace NVMe admin commands that
    are currently not handled by the NVMF subsystem.

    The handler implementation is pretty generic and the handler function
    has to figure out what to do with the command based on the bdevs
    that are configured for the subsystem.
    In cases where admin commands need to be forwarded to an NVMe bdev,
    the commit provides functions that allow access to the underlying bdev.

    There is an example handler in lib/nvmf/custom_cmd_hdlr.c.

0bfaaace8f sock: Add impl_name parameter in spdk_sock_listen/connect.
Purpose: With this patch,

(1)We can support using different sock implementations in
one application together.

(2)For one IP address managed by kernel, we can use different method
to listen/connect, e.g., posix, or uring. With this patch, we can
designate the specified sock implementation if impl_name is not NULL
and valid. Otherwise, spdk_sock_listen/connect will try to use the sock
implementations in the list by order if impl_name is NULL.

Without this patch, the app will always use the same type of sock implementation
if the order is fixed. For example, if we have posix and uring together,
the first one will always be uring.

a27a377ac4 nvmf/rdma: make disconnect qp from cm event safe.
The call to update_ibv_state could result in a segfault if the other
thread had already freed the qp and was just spinning on handling the
rdma event. By not updating the qpair state here, I don't think that we
lose any information about the qpair state. Especiallyy since just a
little bit later we update the qpair state to be in error.
There is nothing in the man pages about the cm events changing the ib
state although I imagine they are closely related. I just say that
because I believe that's why the update was originally in that spot.

fixes: GitHub issue #1110

dc84fbaaa1 rdma: Add synchronization for LAST_WQE_REACHED event
The following scenario might occur when nvmf_tgt is stopped:
1. nvmf_tgt receives SIGINT, changes state to NVMF_TGT_FINI_STOP_SUBSYSTEMS
2. In this state nvmf_tgt stops all subsystems and disconnects associated qpairs
3. In the case of RDMA qpair, its state will be changed to IBV_QPS_ERR.
Once qpair changes the state to IBV_QPS_ERR, RDMA device generates
LAST_WQE_REACHED event when there are no more WQE that can be sonsumed
from the SRQ by this qpair.
4. When all subsystems are stopped, some of qpair may still be alive since they
haven't received LAST_WQE_REACHED event yet.
5. nvmf_tgt stops all poll groups and forcefully destroyes any qpairs linked to them.
6. At this moment LAST_WQE_REACHED event might be generated and received in another thread.
Handler of this event sends a message with a pointer to qpair. The qpair itself may already
be destroyed.
7. Thread that owned qpair receives a message (LAST_WQE_REACHED) with a pointer to alredy destroyed qpair and
destroyes it for the second time when all pointer are invalid.

ibv events related to qpair should be handled by the thread that
owns this qpair. This commit adds a new structure that describes
ibv event, helper functions for sending the event and a list
of events per rdma qpair; add syncronization for LAST_WQE_REACHED event

Fixes #1075

4ea996ce19 nvmf/rdma: dont refer to rtransport when poll_group_create failed
This issue was found by code inspection.
It only occurs when pdk_nvmf_transport_poll_group_create()
itself calls spdk_nvmf_transport_poll_group_destroy().
Other transports at this time do not show this issue.

spdk_nvmf_rdma_poll_group_destroy() depends on
rgroup being assigned a transport, which is only being
done on generic nvmf layer using
spdk_nvmf_transport_poll_group_create()
after successful spdk_nvmf_rdma_poll_group_create().
When failure occurs during create, such assignment was not
performed so any references to rtransport will segfault.

ac03d9206f nvmf: Use correct error code on bad reservation report command
The NVMe-oF target requires 128-bit identifiers for reservations,
so the extended report format must be used. If the user issues
a reservation report command without the extended format bit set,
the specification says to fail it with the HOSTID_INCONSISTENT_FORMAT
error code.

08273e77de tcp: Fix no tcp_req issue while using async writev later.
Purpose: But if we use asynchronous writev
for pdu sending, the call_back of writev may occur
after the new data coming. So it means that the
free tcp request may not be available.
So we use the strategy to check the request status
in TCP_REQUEST_STATE_TRANSFERRING_CONTROLLER_TO_HOST.

So the strategy is checking the state_cntr of all the
reqs in TCP_REQUEST_STATE_TRANSFERRING_CONTROLLER_TO_HOST
state.
1 If the state_cntr > 0, we should queue
the new request.
2 If the statec_cntr == 0, it means that
there is no available slot for the new tcp request
, i.e., the new nvme command comming from the initiator.
If we receive this, it means that the initiator sends more
requests,and we should reject it.

e9be9df45f nvmf/tcp: Fix the potential issue of connection construction.
When we use async writev (e.g., lib io_uring), we find that
the callback of writev is executed after recving the new
data from the initiator, and this is possible.

For example, if the NVMe-oF TCP target receives the ic_req from the
initiator, and sendout the ic_resp, the state  of tqpair will change from
invalid to running until the callback is executed. And the data of ic_resp
is already sent to the initiator, and we receive the new command later. However,
we may still not get the call back function executed
(i.e, spdk_nvmf_tcp_send_icresp_complete). And it is possible
for using lib io_uring, I faced this issue when using lib uring.

And this patch can fix this issue.
