Aspects of bit fields are 'implementation defined'. On some platforms
alignment will occur if two adjacent fields are of different types. This
occurs in spdk_nvme_feat_async_event_configutation after the crit_warn
member which is effectively an int8_t, followed by an int16_t. There
isn't a generic way of changing the compiler's behaviour, so the best
options are:
- Change crit_warn to a uint32_t bit field and copy the value to/from
a spdk_nvme_critical_warning_state variable to use it. This requires
changes to code using the field.
- Adjust the structure definition to use smaller types to avoid the
problem. This preserves existing semantics, but the field order will
need to be reviewed if big-endian support is ever added (other places
in nvme_spec.h will need similar attention). A second reserved field
is required.
Use smaller types which seems the most straightforward option. Adjust
the use of the spdk_nvme_feat_async_event_configuration reserved fields
in lib/nvmf/ctrlr.c.
The new structure is binary compatible and the fields behave in the same
way, with the exception of an additional reserved field, so updating
CHANGELOG.md probably isn't necessary.

There is a chance that admin qpair is being destroyed at
the moment when IO qpair is added to a controller due to e.g.

is change of qpair's state to DEACTIVATING and removing it
from poll group. We can check admin qpair's state and poll
group pointer before sending a message to poll group's thread

There is a public API spdk_nvmf_qpair_get_listen_trid() and it can
get trid of the specified qpair safely for any transport including
pluggable transports.
The API was overlooked when implementing the multipath feature for
NVMe-oF target. trid pointer was added to struct spdk_nvmf_qpair and
was used to find a subsystem listener.
However, pluggable transports got seg. fault because trid of the
qpair was not set.
To avoid such segmentation fault for any transport, change
nvmf_ctrlr_create() to use spdk_nvmf_qpair_get_listen_trid().
The struct spdk_nvmf_qpair is located in the public header file,
and so leave the added trid for now. It will be deprecated eventually.

Fixes issue #1635.
Under rare circumstances, the CC.en and CC.shn are both set
which then results in setting the association timer twice.
This scenario was observed during hot plug testing when the
initiator tries to reset the subsystem that contains the
removed device.
The end result is that when the ctrlr is destructed, then
one of the timers can still fire and access freed memory.

If the initiator sends a property set command to a valid register, but
the value contains bits that are reserved by the NVMe specification,
don't fail the whole command. Just log an error message.
Previously, any valid bits set would take effect but then the command
would also fail. That confuses the initiator and thinks it must retry
the full property set.

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.

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.

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.
