This patch eliminates all use of the word engine that meant the

Admin passthrough supported retry and failover as same as I/O by
using the bdev_retry_count. However, doing retry or failover for
admin passthrough may have unexpected side effects and its value
is not clear. The safest way is to limit retry and failover for I/O.
If we need to support retry and failover for admin passthrough,

This allows mapping an nvme_request back to the

This requires bumping up the max number of arguments per

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

This will allow us to map spdk_bdev_io events

Since we pass the nvme_bdev_io to the nvme driver
(not the spdk_bdev_io), we need to add tracepoints
for the nvme_bdev_io so that spdk_trace can
do the spdk_bdev_io->nvme_bdev_io->nvme_request

An alternative would have been to pass the spdk_bdev_io

seemed to invasive, and I think we will find other

nvme_ctrlr_init_ana_log_page() had used cdata->mnan as active ns count
to allocate a buffer and read a ANA log page into the buffer.
However, cdata->mnan was larger than the real active ns count and caused
an issue when the corresponding NVMe-oF target set the bit 18 of the SGL
support field in the Identify Controller Data structure.
We still need to use cdata->mnan to allocate the buffer because
number of namespaces may be increased dynamically after initialization.
Hence, rename nvme_ctrlr::ana_log_page_size to
nvme_ctrlr::max_ana_log_page_size and calculate and use the active ns
count to read the ANA log page. Check if the current ana_log_page_size
is not larger than nvme_ctrlr->max_ana_log_page_size.

Calculation of the ANA log page size should use the
identify ctrl MNAN field
(maximum number of allowed namespaces)
not the NN (maximum valid nsid value).
An ANA-enabled controller must have a non-zero MNAN value,
see NVMe Base Specification, Figure 251,
therefore nvme_ctrlr_init_ana_log_page() may safely use MNAN.
Since NN might be much higher than MNAN,
ANA log size based on NN may results in a very large
log page and cause a failure to get ANA log,
e.g. if it is larger than the controller's MDTS.
Fix: replace cdata->nn with cdata->mnan
in nvme_ctrlr_init_ana_log_page()

Almost all of these files share the exact same license text,

The following patches will swap the ordering of destroying I/O qpairs
and disconnecting a controller for PCIe transport to fix a github issue.
Setting callback and calling spdk_nvme_ctrlr_disconnect() have been
executed in two cases now.
After the following patches, these will be executed in three cases.
Factoring out these into a helper function will be rewarded.

For PCIe transport, destroying I/O qpairs will be as the completion

The NVMe bdev module supported active-passive policy for multipath mode
first. By this patch, the NVMe bdev module supports active-active policy
for multipath node next. Following the Linux kernel native NVMe multipath,
the NVMe bdev module supports round robin algorithm for active-active
policy.
The multipath policy, active-passive or active-active, is managed per
nvme_bdev. The multipath policy is copied to all corresponding
nvme_bdev_channels.
Different from active-passive, active-active caches even non_optimized
path to provide load balance across multiple paths.

If we specify a preferred path manually for each NVMe bdev, we will
be able to realize a simple static load balancing and make the failover
more controllable in the multipath mode.
The idea is to move I/O path to the NVMe-oF controller to the head of
the list and then clear the I/O path cache for each NVMe bdev channel.
We can set the I/O path to the I/O path cache directly but it must be
conditional and make the code very complex. Hence, let find_io_path() do
that.
However, a NVMe bdev channel may be acquired after setting the preferred
path. To cover such case, sort the nvme_ns list of the NVMe bdev too.
This feature supports only multipath mode. The NVMe bdev module supports
failover mode too. However, to support the latter, the new RPC needs to
have trid as parameters and the code and the usage will be come very
complex. Add a note for such limitation.
To verify one by one exactly, add unit test.

ACWU and NACWU are 0-based values. But spdk_bdev_get_acwu()
specifies the compare-and-write-unit in terms of blocks
(i.e. 1-based). So the bdev/nvme module needs to add 1
to this value before registering the bdev.

When sending a fused compare and write command, we pass a callback
bdev_nvme_comparev_and_writev_done that we expect to be called twice
before marking the io as completed. In order to detect if a call to
bdev_nvme_comparev_and_writev_done is the first or the second one, we
currently rely on the opcode in cdw0. However, cdw0 may be set to 0,
especially when aborting the command. This may cause use-after-free
issues and this may call the user callbacks twice instead of once.
Use a bit in the nvme_bdev_io instead to keep track of the number of
calls to bdev_nvme_comparev_and_writev_done.

Add an new RPC bdev_nvme_get_io_paths to query all active I/O paths.
One io_path belongs to One nvme_bdev_channel.
Each nvme_bdev_channel is associated with one nvme_bdev.
If the RPC bdev_nvme_get_io_paths has a bdev name as a parameter
it can use spdk_for_each_channel() simply for the corresponding
nvme_bdev.
However, users will want to know I/O paths of all nvme_bdevs like
the RPC bdev_get_bdevs.
One io_path has one nvme_qpair. One nvme_qpair belongs to one
nvme_poll_group. By relying on these relationships, the RPC
bdev_nvme_get_io_paths traverses all nvme_poll_groups by using
spdk_for_each_channel() to g_bdev_nvme_ctrlrs.
The RPC bdev_nvme_get_io_paths has two modes, display all or
the specified NVMe bdev's active I/O paths.
The specified bdev name is used just for comparison and empty
array is returned if no matched io_path is found.

Previously, if a namespace is in ANA inaccessible state, I/O had been
queued infinitely. Fix this issue according to the NVMe spec.
Add a temporary poller anatt_timer and a flag ana_transition_timedout for
each nvme_ns.
Start anatt_timer if the nvme_ns enters ANA transition. If anatt_timer
is expired, set ana_transition_timedout to true. Cancel anatt_timer or
clear ana_transition_timedout if the nvme_ns exits ANA transition.
nvme_io_path_become_available() returns false if ana_transition_timedout
is true.

Previously, only if admin qpair gets error, bdev_nvme_failover() was
called.
However, I/O qpair may get error earlier than admin qpair. In this case,
bdev_nvme_failover() was called but reset was already in progress. So
bdev_nvme_failover() returned without doing anything.
bdev_nvme_reset_complete() executes bdev_nvme_failover() if reset
failed. However the test time of test/nvmf/host/failover.sh was very
short. Timeout came before trying bdev_nvme_failover().
We can replace other bdev_nvme_reset() calls by bdev_nvme_failover()
but this patch focuses on the critical case.
Fixes issue #2128.

After the change that the NVMe bdev module disconnects qpair asynchronously,

We have three cases that disconnected_qpair_cb() is called now, 1) qpair

I/O channel, and 3) qpair detected error, and was disconnected and freed.
Get NOTICELOG for 3) but get DEBUGLOG for 1) and 2) with some rewording.
Additionally, to improve readability, change if-else ordering.

We want to be able to save the discovery configuration

The obvious change needed here is to add a
bdev_nvme_start_discovery RPC to the config file
for each discovery context.
But we also need to make sure we do not emit
bdev_nvme_attach_controller RPCs for controllers
that were attached via the discovery service. These
controllers will be attached by the discovery service
instead - or maybe not at all if the discovery
log page returns different results.
Do both of these changes here, since they are
somewhat tied to each other.
