Following patch made sure that CQ/SQ are allocated in
physically contiguous manner:
(64db67) nvme/pcie: make sure sq and cq are physically contiguous
Using MAX_IO_QUEUE_ENTRIES is enough to make sure that either
queue does not span multiple hugepages.
Yet the patch made sure that whole page is occupied only
by the queue. Which unnecessarily increases memory consumption
up to two hugepages per each qpair.
This patch changes it so that each queue alignment is limited
up to its size.
Changes in hugepages consumed when allocating io_qpair in hello_world
application:
io_queue_size Without patch With patch
256 8MiB 0MiB
1024 12MiB 4MiB
4096 24MiB 16MiB
Note: 0MiB means no new hugepages were required and qpair fits into
previously allocated hugepages (see all steps before io_qpair
allocation in hello_world).
Intersting result of this patch is that since we required alignment
up to the hugepage size this resulted in reserving even two 2MiB
hugepages to account for DPDK internal malloc trailing element.
See alloc_sz in try_expand_heap_primary() within malloc_heap.c
This patch not only reduces overall memory reserved for the
queues, but decreases increase in heap consumption on DPDK side.

If the request contains separate metadata buffer, we should set
PSDT 10b when hardware SGL is supported and dword alignment is
required. SPDK driver doesn't provide SGL metadata data buffer
APIs for now, the separate metadata buffer is alway contiguous,
so we can put the metadata buffer into a data block SGL entry.

Althrough the controller can only support 1 session, but we can refactor
the OPAL internal APIs running based on session, then we can allocate
a session from public APIs, currently we just use the session that
embedded in the global device structure.

Althrough the drive reports that only one session and one comID are
supported, and it can only support synchronous method, but it should
allow users to send multiple security send/receive commands at the
same time. Looking back the implementation of existing library, it
works but not so good, here as the first step, we will not use the
global data buffer for security receive command when doing level 0

The revert asynchronous API doesn't run as the *real* asynchronous
way, because the drive can only support synchronous module and only
1 session is supported. The reason why we added this API is that
RPC call has the default timeout value here, while the revert may
take over several minutes, the API itself doesn't short the revert
action, so just remove it and use the synchronous API instead.
The revert action will erase all the users data and bring the drive
back to the factory state, it should run in the synchronous mode,
so just remove the asynchronous API and we can increase the timeout
value when using RPC to call this API.

In this case, nvme_rdma_qpair_process_completions() does not
poll CQ.
However, nvme_rdma_qpair_process_completions() can poll CQ even
when there is no free slot in SQ.
Hence move nvme_rdma_qpair_submit_sends() and
nvme_rdma_qpair_submit_recvs() after the loop to poll CQ.
nvme_rdma_qpair_submit_sends() and nvme_rdma_qpair_submit_recvs()

In the autotest, when calling kill_stub() function, there is error log
like this: "Device 0000:83:00.0 is still attached at shutdown!", so it's
better to detach the controller when exit the stub process.
But after call spdk_nvme_detach() in the stub process, there is another issue:
1. NVMe stub running as the primary process, and it will send 4 AERs.
2. Using NVMe reset tool as the secondary process.
When doing NVMe reset from the secondary process, it will abort all the
outstanding requests, so for the 4 AERs from the primary process, the 4
requests will be added to the active_proc->active_reqs list.
When calling spdk_nvme_detach() to detach a controller, there is a
assertion in the nvme_ctrlr_free_processes() at last to check the
active requests list of this active process data structure.
We can add a check before destructing the controller to poll the
completion queue, so that the active requests list can be flushed.

A pointer to a stack variable is passed as an argument to
nvme_completion_poll_cb function, later this variable is used
to track completion in the spdk_nvme_wait_for_completion() function.
If normal scenario a request submitted to the admin queue will be completed
within the function which submitted the request.
spdk_nvme_wait_for_completion() calls nvme_transport_qpair_process_completions
which may return an error to the caller, the caller may exit from the
function which submitted the request and the pointer to the stack variable
will no longer be valid. Thereby the request may not be completed at that time
and completed later (e.g. when the controller/qpair are destroyed)
and that will lead to call to nvme_completion_poll_cb with the pointer
to invalid stack variable.
Fix - Dynamically allocate status structure to track the completion;
Add a new field to nvme_completion_poll_status structure to track status
objects that need to be freed in a completion callback

when they are available. As part of doing so we remove the error
return in the socket layer writev_async implementation for sockets
that don't have a poll group.

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.

For nvme Opal, most of the commands are a combination
of security send and receive. There are cases that
application send the security send command and is
shutdown before sending security receive command.
In these cases, when the application restarts, an opal
command will send security send command again and will
cause command sequence error.
Thus, we do a receive first and memset the response
buffer before security send and receive.

the queued_req list due to limited resources, in the completion path, we
may resubmit them to the controller. When the controller was removed
the submission path will return -ENXIO and we will free the requests directly,
so the callback will not be trigerred for these requests. Here we added a

submission, we can triger user's callback.

Some version of firmware on Intel SSDs exhibit poor performance
with an IO queue size of 256 (the SPDK default). Add a quirk to
account for this - and use the same size as the Linux driver (1024)
instead.
If the user specified a controller option to explicitly set the
io_queue_size different than the default, the quirk will not take
effect. Note that users can still override the io_queue_size when
creating the qpair - this only changes the ctrlr's default
io_queue_size.

If setting lock fails, index is incremented.

There are a couple of places where we check against
transport_qp_is_failed and then immediately check to see if we are in
the connected state. If we are failed, or we are not in the connected
state we return the same value to the calling function.
Since the checks for transport_qpair_is_failed are not necessary, they
can be removed. As a result, there is no need to keep track of it and it
can be removed from the qpair structure.

NVMe hotplug must be monitored in the primary process -
DPDK doesn't support trying to handle it in the
secondary process.
This issue was somewhat masked previously in secondary
processes, since usually it would just probe(NULL) which
meant probe all attached NVMe controllers. So in the
secondary process, we would probe just once, and create
the hotplug fd - it would never actually try to monitor
it.
But when explicitly specifying multiple trids in a
secondary process, probe would get called multiple
times. First time would be fine since it only creates
the hotplug fd. But second time would segfault since
monitoring for hotplug requires checking the DPDK-allocated
context which doesn't exist in the secondary process.

Disconnecting qpairs from the admin thread during a reset led to an
inevitable race with the data thread. QP related memory is freed during
the disconnect and cannot be touched from the other threads.
The only way to fix this is to force the qpair disconnect onto the
data thread.
This requires a small change in the way that resets are handled for
pcie. Please see the code in reset.c for that change.

If we disconnect qpairs without taking the lock, we run the risk of
trying to double free qpair resources before they have been marked as
NULL.
For example, polling on one thread and calling
nvme_rdma_qpair_disconnect from one thread while doing an
nvme_ctrlr_reset on another thread. nvme_ctrlr_reset will call down to
nvme_rdma_qpair_disconnect on the same qpair and without any locking it
can result in trying to destroy the qpair resources multiple times.

check_enabled had a couple bugs in it that made it unfriendly for enabling
I/O qpairs after a reset.
1. It was calling nvme_qpair_abort_queued_requests before setting the
enabled flag to true. For applications that submit new I/O in the
completion callback for old I/O, this means you enter an infinite loop
of submitting requests, and then immediately completing them. SO
instead, wait for the qpair to reset, then just submit those requests to
the lower layer.
2. It didn't check whether we were already in the middle of calling it,
so we could reenter function calls like
nvme_qpair_abort_queued_requests.
Also, now that we have a coherent state machine for qpairs, we can limit
the enabling to a specific state in that state machine.

For fabric controllers, a lot of the early initialization operations such

As a side effect of this cahnge, the internal API
nvme_ctrlr_enable_admin_qpair has been removed. It would have turned

My recent changes that introduced batching to queued request
resubmission also introduced a regression that can lead to reordering
requests before submitting them to the drive. This change prevents that.
We wait until inside the internal _nvme_qpair_submit_request function to
check for queued entries to avoid queueing a request that has children.
If a request that has children gets queued, when we process completions
and resubmit the parent, it will result in the children being submitted.
Since we only account for the number of requests we completed in the
last iteration, some of the child requests may be requeued out of order,
or worse, none of the child requests will end up being submitted to the
transport and they will all be queued behind previously queued requests.

By moving the contents of spdk_nvme_ctrlr_reset to a new internal
function, I am paving the way for providing two reset paths. One, which
can be used by the user as an external API function and which provides
the same legacy behavior. Specifically, that it will always fail the
ctrlr after an attempted reset, and a second, internal path, which will
be used by the qpair reconnect code which will defer failing the qpair
to the qpair code.

This patch, and the several following patches are aimed at creating a
mechanism for reporting up to the application layer that a controller is
failed and or removed. To do this, I use the reset_cb to inform the
upper layer that the controller is failed.
This also requires changes to how we handle a controller reset to

In most places, we are passing NVME_TIMEOUT_INFINITE as the
timeout_in_ms argument to nvme_ctrlr_set_state, presumably in an attempt
to specify an infinite timeout. However, nvme_ctrlr_set_state only
checked against 0 when setting the actual timeout, and we didn't have
any logic to check for overflow so we just ended up setting random
timeout_tsc values which changes the behavior of the
nvme_ctrlr_process_init function in several places.
So, change NVME_TIMEOUT_INFINITE to 0, and add some integer overflow
checking to nvme_ctrlr_set_state.

spdk_pci_device_claim() could create a file on the
filesystem that couldn't be deleted programatically.
It could only be overwritten - e.g. by another spdk
instance - but this didn't really work if that
another instance had less privileges and hence no
access to the previous file.
This is exactly the case we're seeing on our CI when
running SPDK as non-root. In general it's a good idea
not to leave any leftover files, so now we'll delete
the pci claim file when the spdk process exits.
spdk_pci_device_claim() used to return a file descriptor
that could be simply closed to "un-claim" the device.
It'll now return only a return code. The fd will be
stored inside spdk_pci_device and will be closed either
when user calls the newly introduced spdk_pci_device_unclaim(),
or when the device is detached.
We'll still need to clean up those files somewhere in
our test scripts (probably ./setup.sh cleanup) to
clean up after crashed processes or so - but we don't
necessarily want to run such scripts inside the autotest
whenever a non-root spdk is about to be started.

This reverts commit 6129e78d26.
When the initiator sends the discovery log page, if the log page
exceeds the size of its data buffer, it will break it up into
multiple log page commands with appropriate offsets. However,
supporting offsets in log pages is an optional feature in NVMe
and reported by the EDLP bit in the identify data.
This commit changed the discovery process to no longer send an
identify command prior to doing the discovery log page command,
so the values in the identify data are always 0. If the discovery
log page exceeds the size of the data buffer (4k), it will then
fail to send the second log page with an offset because it
believes the controller does not support the feature.
Revert this change to fix it. An identify should always be sent
as part of the discovery process. A test case is included in a
follow up patch the demonstrates the bug.

There are many req leaks when a controller failure
occurs during submitting IO. It must free all of
the children before freeing the parent req.
If a part of the child req has been sent to the back end
and a part of the child req fails, removes the failed req
from the parent req and the parent req must be retained,
freeing the parent req after all of the submitted reqs return.

This change attempts to address the Trello request to decode I/O errors in
NVMe hello_world example.
See https://trello.com/c/MzJJw7hM/2-decode-io-errors-in-nvme-helloworld-example
As part of this change, spdk_nvme_cpl_get_status_string was declared
in nvme.h, and spdk_nvme_qpair_print_command and
spdk_nvme_qpair_print_completion were renamed and added to nvme.h,
allowing all three to used "externally."
To test the failing paths, two compile time defines were added to force a
write or read error (bad LBA) respectively.
As the example does a read after write, if the write fails, the example fails.

SPDK NVMe-oF initiator driver could not transfer IO whose size is
more than 128KiB even if NVMe-oF target allows IO whose size is
more than 128KiB both for RDMA and TCP transport.
Some use cases need to transfer IO larger than 128KiB.
For RDMA transport, max_mr_size by ibv_query_device of RDMA devices
indicates the maximum size of a single memory region and is independent
from the actual I/O size, and is very likely to be larger than 2 MiB
which is the granularity we currently register memory regions.
Actually some RDMA NICs return UINT64_MAX for max_mr_size by ibv_query_device.
Hence use UINT32_MAX and let the generic layer use the controller data
to moderate this value.
On the other hand, for TCP transport, there is no limit for maximum IO
size and hence use UINT32_MAX.
Besides, for RDMA transport, max_sges should be the minimum of
max_sge got by querying RDMA devices and NVME_RDMA_MAX_SGL_DESCRIPTORS.
Hence do this change together in this patch.

NVMe/TCP target had assumed the size of each iovec was io_unit_size.
Using nvme_tcp_pdu_set_data_buf() instead removes the assumption
and supports any alignment transparently.
Hence this patch moves nvme_tcp_pdu_set_data_buf() to
include/spdk_internal/nvme_tcp.h and replaces the current code to use it.
Besides, this patch simplifies spdk_nvmf_tcp_calc_c2h_data_pdu_num()
because sum of iov_len of iovecs is equal to the variable length now.
We cannot separate code movement (lib/nvme/nvme_tcp.c to include/
spdk_internal/nvme_tcp.h) and code replacement (lib/nvmf/tcp.c)
because moved functions are static and compiler give warning if
they are not referenced in lib/nvmf/tcp.c.
The next patch will add UT code.

nvme_tcp_pdu_set_data_buf() has been used to process C2H and H2C for
NVMe/TCP initiator.
In this case, NVMe/TCP cuts out the part of the input data buffer
and transfers the part, and repeats these cut and transfers until
the whole data buffer is transferred. NVMe/TCP uses two SGLs, and
use one to parse from the offset datao to datao + datal and another
to append from the offset 0 to datal.
However, the current nvme_tcp_pdu_set_data_buf() had used
data_length as not data length of this transfer but total length
of the whole transfers by mistake.
Recently DIF library updated to properly handle very similar
cases, and so this patch takes DIF library as a reference and
corrects the implementation.
The next patch will add UT code to verify the bug will be fixed.
The code size is pretty large and so UT code is separated.

This patch is the first patch of the patch series.
The purpose of this patch series is to correct the bug of
nvme_tcp_pdu_set_data_buf() when the multiple iovecs array is
passed, to share nvme_tcp_pdu_set_data_buf() between NVMe/TCP
initiator and target, and utilize nvme_tcp_pdu_set_data_buf()
not only for C2H and H2C but also in-capsule data in NVMe/TCP
target.
This patch is necessary to satisfy the second requirement, to
share nvme_tcp_pdu_set_data_buf() between NVMe/TCP initiator and target
because struct nvme_tcp_req and struct spdk_nvmf_tcp_req are different.
Four variables, iov, iovcnt, data_offset, and data_len are common,
and hence this patch changes the parameters of nvme_tcp_pdu_set_data_buf()
to accept them.
The bug is fixed in the next patch and tested in after the next patch.

Adds fields to structure spdk_nvme_io_qpair_opts.
These fields allow specifying the locations of memory buffers used
for the submission and/or completion queues.
By default, vaddr is set to NULL meaning SPDK will allocate the memory to be used.
If vaddr is NULL then paddr must be set to 0.
If vaddr is non-NULL, and paddr is zero, SPDK derives the physical
address for the NVMe device, in this case the memory must be registered.
If a paddr value is non-zero, SPDK uses the vaddr and paddr as passed.
SPDK assumes that the memory passed is both virtually and physically
contiguous.
If these fields are used, SPDK will NOT impose any restriction
on the number of elements in the queues.
The buffer sizes are in number of bytes, and are used to confirm
that the buffers are large enough to contain the appropriate queue.
These fields are only used by PCIe attached NVMe devices. They
are presently ignored for other transports.

Currently the nvme driver will always log any
request completed with error status. Some
applications may not want this behavior. So provide
an option to disable it at the controller level.
When this option is enabled, any failed requests
from queues associated with that controller
(including the admin queue) will not log the
failed request.
Of course the application will still receive
the failed status code and can decide to do its
own logging there.

enough ibv_sge objects in it to support up to the maximum number of SGEs

Send the given NVM I/O command, I/O buffers, lists and all to

This is a low level interface for submitting I/O commands directly.
This can only be used on PCIe controllers and qpairs.
This function allows a caller to submit an I/O request that is
COMPLETELY pre-defined, right down to the "physical" memory buffers.
It is intended for testing hardware, specifying exact buffer location,
alignment, and offset. It also allows for specific choice of PRP
and SGLs.
The driver sets the CID. EVERYTHING else is assumed set by the caller.
Needless to say, this is potentially extremely dangerous for both the host
(accidental/malicionus storage usage/corruption), and the device.
Thus its intent is for very specific hardware testing and environment
reproduction.

This is an attempt to fix device hotremove with VFIO.
A soft device hotremove request through sysfs [1] would
currently just block until the SPDK process manually
releases that device - e.g. upon an RPC request.
VFIO won't get unbound from the device untill userspace
releases all its resources. VFIO can signal a pending
hotremove request by kicking any file descriptor provided
by the userspace - and DPDK does provide such descriptor -
but SPDK does not listen on it.
DPDK does offer handy API to listen and in this patch
we make use of it inside our env/pci layer. Within
a DPDK callback we set an internal per-device hotremove
flag, which upper-layer SPDK drivers can poll with a new
env API - spdk_pci_device_is_removed().
The VFIO hotremove event will be sent to primary
processes only, so that's where we listen.
We make use of this new API in the NVMe hotplug poller,
which will process it just like any other supported
hotremove event.

Althrough SPDK already provides a API to users which
can process runtime timeout NVMe commands, but it's
nice to have another API here, SPDK NVMe driver can
use it to break the endless wait. Also use the API
first in the initialization process, because we don't
want to add another initialization state with Intel

The patch is used to fix issue:

Reason: For supporting sgl, the implementation of
function nvme_tcp_pdu_set_data_buf is not correct.
The translation is not correct for incapsule data
when using SGL. In order not to do the translation
via calling sgl function again, we use a variable

However, some SPDK applications, e.g. nvme/perf, in addition
to using spdk_nvme_transport_id_parse() also check for the
existence of a "ns" key in the transport id string to limit

The RDMA memory map needs to be per-protection
domain, not per NVMe controller. Otherwise, when
an NVMe controller is removed, the memory map may
reference an invalid pointer to a detached

In cases we probe without a specific trid, the underlying
rte_bus_probe() in spdk_pci_enumerate() might fail to
initialize some devices, but still return with code 0,
That's technically correct, as we asked just to probe
devices on the bus and that's what it did. Some devices might
have been initialized, others not. In secondary process we
blindly assumed all devices were probed successfully, which
might have eventually led to assert failures, as current
process was not on the ctrlr->active_procs list.
To fix it, just add an additional check before attaching
the controller in secondary process.

We only detached the PCI device on the controller destruction,
which happens just once - in the primary process, but secondary
process needs the PCI detach as well.
Requesting to hotremove the NVMe PCIe controller in secondary
process is broken, because DPDK will still keep the device
reference and won't allow SPDK to hotplug it again.
Fix this by detaching the local PCI device whenever removing
a secondary process from spdk_nvme_ctrlr. This does require
an additional transport check in the generic NVMe layer, but
I found it an overkill to create a multi-process transport
abstraction just for this case.

The time required to wait increases with the amount of submitted
FLR resets. Now that DPDK takes less and less time to initialize,
this starts to become an issue. We can even see on our CI within
regular tests where a single application is start-stopped in
a short period of time. This is also a problem if a device is
detached via RPC and immediately attached afterwards.
The time required to wait seems to cap at 2 seconds, so instruct
our driver to wait exactly that.

This is an NVMe-specific issue and I/OA or VirtIO devices don't
need it. Additionally, the delay is now asynchronous, meaning
that potentially multiple NVMe controllers can wait all at once.
The drawback of this change is that we're needlessly waiting
even when using uio_pci_generic. However, since the delay does
not block anymore, its impact is significantly minimized.
