cdf61c2f22 nvme: Polls only the qpair if ctrlr is not fabrics when connecting synchronously
For non-fabric controllers, the corresponding I/O qpairs are simply
re-enabled at controller reset.

This had a issue when I/O qpairs span multiple threads and poll group
is used.

spdk_nvme_ctrlr_reconnect_poll_async() calls
nvme_transport_ctrlr_connect_qpair() with qpair->async being false.
Then nvme_transport_ctrlr_connect_qpair() calls
spdk_nvme_poll_group_process_completions() until the qpair is connected.
spdk_nvme_poll_group_process_completions() may poll other qpairs.
This may cause I/O to complete on a wrong thread.

For PCIe controller, spdk_nvme_poll_group_process_completions() calls
spdk_nvme_qpair_process_completions() simply for each qpair.

Hence change nvme_transport_ctrlr_connect_qpair() to call
spdk_nvme_qpair_process_completions() if the controller is non-fabrics.

0e4b13dc53 nvme_rdma: Destroy qpair after it is disconnected and drained
By the previous patches, a qpair is destroyed after it is actually
disconnected.

But after the qpair is destroyed, it is checked if drained by using
rqpair->current_num_sends and rqpair->current_num_recvs.

However, if the qpair is the last of a poller of a poll group,
CQ is destroyed before checking if the qpair is drained.

If CQ is destroyed, at least rqpair->current_num_recvs is not updated,
and we may get one second timeout.

This should be avoided.

Hence, destroy the qpair after it is disconnected and drained.

1d58eb038b nvme_rdma: Release poller from poll group when qpair is actually disconnected
If the being disconnected qpair is the last of a poller of a poll group,
CQ is destroyed and the poller is released before the qpair is actually
disconnected.

This patch destroy CQ and release the poller after the qpair is actually
disconnected.

One exception is when spdk_nvme_ctrlr_free_io_qpair() is called to a
connected qpair. In this case, the qpair is removed from a poll group
before the qpair is actually disconnected. In this case, destroy CQ and
release the poller when the qpair is removed from the poll group.

b90d7b5b43 nvme: add admin queue size quirk for Hyper-V
Hyper-V NVMe SSD controllers require admin queue
size to be even multiples of a page. Add quirk to
adjust the admin queue size if user overrides the
default value to something other than an even
multiple.

As part of this change, set the quirks earlier
when constructing a pcie controller, so that the
quirks value can be used in the generic
nvme_ctrlr_construct() function.

4a6f858872 nvme_rdma: Set REUSEADDR to reuse source address among multiple CM IDs
When we specify source address for admin and I/O qpairs,
rdma_resolve_addr() succeeded only for admin qpair and failed for
following all I/O qpairs because rdma_resolve_addr() returned
-EADDRINUSE.

To reuse source address among multiple qpairs, set the REUSEADDR option
for each CM ID before executing rdma_resolve_addr() if source address
is specified.

We may miss something. Even if rdma_set_option() fails, execute
rdma_resolve_addr().

4300c62167 nvme: add spdk_nvme_ctrlr_disable_read_changed_ns_list_log_page()
Commit a119799b ("test/nvme/aer: remove duplicated changed NS list log")
changed the nvme driver to read the CHANGED_NS_LIST log page before
calling the application's AER callback (previously it would read it
after).

Commit b801af090 ("nvme: add disable_read_changed_ns_list_log_page")
added a new ctrlr_opts member to allow the application to tell the
driver to not read this log page, and will read the log page itself
instead to clear the AEN.  But we cannot add this option to the 22.01
LTS branch since it breaks the ABI.  So adding this API here, which
can then be backported manually to the 22.01 branch for LTS users
that require it.

Restoring the old behavior is not correct for applications that
want to consume the CHANGED_NS_LIST log page contents itself to
know which namespaces have changed.  Even if the driver reads the
log page after the application, that read could happen during a
small window between when a namespace change event has occurred and
the AEN has been sent to the host.  The only safe way for the
application to consume ChANGED_NS_LIST log page contents itself
is to make sure the driver never issues such a log page request
itself.

Fixes issue #2647.

e36f0d363e nvme/pcie, nvme/tcp: add cb_arg context tracepoint argument
This allows mapping an nvme_request back to the
nvme_bdev_io.

This requires bumping up the max number of arguments per
tracepoint.  5 was previously chosen as max since it
exactly fit in 64 bytes (1 cacheline) when all
arguments were stored as uint64_t, but now that we
support uint32_t arguments we can afford extra
arguments when some of them are uint32_t.  I've
bumped it to 8 so we can avoid having to touch
this value multiple times if we find some cases
where we need 7 or 8 args.

c50cb569de include: add STATIC_ASSERTS for opts structures with size member
Various opts structures in SPDK have a size member, to enable
ABI compatibility should fields be added in the future.

But this requires the strucures to be packed, otherwise for
example a structure may be padded at the end, and a new
field added may just consume some of that padding.

So add STATIC_ASSERTS for the current sizes in this
patch.  Upcoming patches will make the structures packed
and add in reserved fields to fill in holes.

Get a PD for the device from the PD pool managed by the RDMA provider
when creating a QP, and put the PD when destroying the PD.

By this change, PD is managed completely by the RDMA provider or the hooks.
nvme_rdma_ctrlr::pd was added long time ago but is not referenced
anywhere. Remove nvme_rdma_ctrlr::pd for cleanup and clarification.

a818564374 nvme: check CSTS.CFS when initializing ctrlrs
If Controller Fatal Status (CFS) bit is set, there's no point in waiting
for CSTS.RDY and the only way to move forward with the initialization is
to perform a controller reset.

This fixes issues with test/nvme/sw_hotplug.sh when running under qemu.
It seems that during that test, qemu marks the emulated NVMe drives as
fatal, so if we didn't check CSTS.CFS, the initialization would time
out.

Fixes #2201.

3b26e2c594 nvme/rdma: Create poller and CQ on demand
Original implementation creates pollers and CQs for all discovered
devices at poll group creation. Device (ibv_context) that has no
references, i.e. has no QPs, may be removed from the system and
ibv_context may be closed by rdma_cm. In this case we will have a CQ
that refers to closed ibv_context and it may crash in ibv_poll_cq.

With this patch pollers are created on demand when we create the first
QP for a device. When there are no more QPs on the poller, we destroy
the poller. This also helps to avoid polling CQs that don't have any
QPs attached.

3512714b3f nvme_fabrics: Lock mutext when prcessing set/get regs
That is possible to get/set registers from any thread,
during regs processing we are polling admin qpair to
get a completion. At the same time, another thread
can also poll admin qpair and that can lead to
undefined behavior.

This patch fixes an issue when bdev_nvme is configured
with io_timeout. If remote target becomes unresponsive
(e.g. due to link down), IO timeout occurs and bdev_nvme
tries to get csts registers in timeout_cb. At the same
time another thread can process adminq, so we may have
2 simultaneous adminq polls. If admin qpair is disconnecting
at that time (RDMA transport) we may destroy resources
twice from different threads.

We don't see a problem with set_regs function but it
won't be redundant to lock mutex in set_regs as well.

21d15cb043 nvme: cache values in nvme_tcp_req_complete
nvme_tcp_req_complete_safe caches values on
the request, so that we can free the request *before*
completing it.  This allows the recently completed
req to get reused in full queue depth workloads, if
the callback function submits a new I/O.

So do this nvme_tcp_req_complete as well, to make
all of the completion paths identical.  The paths
that were calling nvme_tcp_req_complete previously
are all non-fast-path, so the extra overhead is
not important.

This allows us to call nvme_tcp_req_complete from
nvme_tcp_req_complete_safe to reduce code duplication,
so do that in this patch as well.

enforcing this. Unfortunately, it seems to have two bugs:

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names

Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

4295661eb8 nvme_tcp: fix bug about qpair stuck in CONNECTING state
When running perf test, sometimes after CONNECT req's resp was
received and processed, the qpair still failed to change from state
CONNECTING to CONNECTED. For when it goes to nvme_fabric_qpair_connect_poll
-> nvme_wait_for_completion_robust_lock_timeout_poll to process the
CONNECT req's resp, the req may have not been finished in sock_check_zcopy,
although its resp has been received and processed, which means the
tcp_req->ordering.bits.send_ack is still 0 and the status->done still
is false. And after the req is completed in sock_check_zcopy, we need
to poll this qpair again to make the state enter CONNECTED.

And if icreq's resp received and processed before nvme_tcp_send_icreq_complete
is called by _sock_check_zcopy, the qpair will be stuck in CONNECTING
and it never proceed to send the CONNECT req. We also need to put it
in pgroup->needs_poll to fix it.

I can reproduce this bug with the following configuration.
target: 16NVMe SSD, running on 20 cores;
initiator: randread test using nvme perf with 32 cpu cores and
zerocopy enabled.

The error doesn't always occur. CONNECT failure is about 1 failure in
ten with the following log. And icreq failure is less frequent with
only target side's "keep alive timeout" log.

Error reported in initiator side:
Initialization complete. Launching workers.
[2022-05-23 14:51:07.286794] nvme_qpair.c: 760:spdk_nvme_qpair_process_completions:
*ERROR*: CQ transport error -6 (No such device or address) on qpair id 2
ERROR: unable to connect I/O qpair.
ERROR: init_ns_worker_ctx() failed

And target side shows:
Disconnecting host  from subsystem nqn.2016-06.io.spdk:cnode2 due to keep alive timeout

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file.  This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text.  There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.
