047c067c05 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 22.05
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

a9593c7981 bdev: Fail nvme passthru command if not supported by bdev
The originally detected problem is that SPDK NVMf target fails command
with invalid opcode with status code INTERNAL_DEVICE_ERROR instead of
INVALID_OPCODE. All unknown commands on IO queue are passed to
underlying block device layer as NVME_IO type. It is not checked if
this type of commands is supported and, when command fails,
INTERNAL_DEVICE_ERROR is set as status code. If command fails on
submission, status code is set to INVALID_OPCODE which is more
relevant.

This patch adds check if command type is supported to
bdev_nvme_*_passthru functions. If not supported, it is failed with
ENOTSUP.

22fa0c0135 bdev: bdev_io_get_nvme_status() supports NVMe abort command
spdk_bdev_io_get_nvme_status() does not follow NVMe abort command
about return values.

NVMe abort command sets completion status to SUCCESS both for success and
failure cases and differentiates only the bit 0 of cdw0.

lib/nvmf do not use spdk_bdev_io_get_nvme_status() but checks only
success or failure at completion.

So there is no issue now but let spdk_bdev_io_get_nvme_status()
follow NVMe abort command. In future, the user of spdk_bdev_abort()
may use spdk_bdev_io_get_nvme_status().

b7ad5b0b90 bdev/zone: add support for get zone id
In the bdev-zone API, there are a few functions that takes a zone_id:
spdk_bdev_get_zone_info(), spdk_bdev_zone_management(), and the
spdk_bdev_zone_append() functions.

The way a zoned application is usually written is that it starts off
by getting the zone report for all zones (zone_id will be sent in as 0),
and then the application will keep the whole zone report in memory.

Therefore, an application usually have access to the zone_id/zslba for
all zones. However, there are cases, e.g. when getting an error on write,
where the completion callback will only have the lba of the write that
failed.

Add a helper function that can be used to get the zone_id/slba for a
given lba. Having this helper in bdev-zone will avoid SPDK applications
needing to provide their own implementation for this.

413d25b036 bdev_module: add async fini_start()
fini_start() is called for each bdev module before
iterating over all unclaimed bdevs to unregister them.
This allows bdev modules to behave differently during
each such unregister. Ex. unloading lvol store when
all lvol bdevs on it are unregistered.

Another use of this callback is to unclaim all bdevs
that can be at that point. Especially ones that will
not receive callback due to no bdev registered.
Ex. offline raid bdev, when some underlying bdevs are missing.

fini_start() being synchronous does not help in cases
where to release claim on the bdev, an asynchronous operation
is required. Ex. lvol store with no bdevs present, requires
async lvs unload to be called.

This patch adds async_fini_start flag for the bdev modules,
to be used when async fini_start is required. When done,
bdev module has to call spdk_bdev_module_finish_start_done().

cf8405fc24 bdev: Hold mutex while removing name from name tree
We had not held mutex while removing bdev name or alias from bdev
name tree for most cases. Fix these in this patch.

spdk_bdev_unregister() already holds g_bdev_mgr.mutex when removing
name, and so we do not need to change it.

spdk_bdev_close() had not held g_bdev_mgr.mutex. What we want to lock
is only when removing name from name tree, that is, calling
bdev_name_del() in bdev_unregister_unsafe(). However, we need to
keep hierarchical lock ordering. Hence get and free g_bdev_mgr.mutex
outside of bdev->internal.mutex.

563f69ebe8 bdev: spdk_bdev_get_by_name() hold mutex itself while traversing bdev name tree
spdk_bdev_register() and spdk_bdev_add_alias() had not held mutex when
adding bdev name or alias to global bdev name tree. This bug caused unexpected
error when traversing global bdev name tree.

The next patch will fix the bug. This patch is a preparation for the fix.

spdk_bdev_get_by_name() had not held mutex while traversing bdev
name tree. The major callers to spdk_bdev_get_by_name() had held mutex
when calling it. However, this was not clear.

Factor out the internal of spdk_bdev_get_by_name() into a helper
function bdev_get_by_name() and then change spdk_bdev_get_by_name()
to lock and unlock when calling bdev_get_by_name().

Then replace spdk_bdev_get_by_name() call in spdk_bdev_alias_add() and
bdev_register() by bdev_get_by_name() call.

spdk_bdev_get_by_name() call in spdk_bdev_examine() is not changed.
This is called only from JSON RPC and not related with the bug. So
we want to fix only unlocked access to global bdev name tree.

6cebe9d06b nvmf: Support physical block size if exposed by bdev
(Note: this patch was previously applied as b32cfc46 and then reverted
as 63642bef.)

Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K

iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16

NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.

This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.

Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

Fixes #1884

There are three modules implementing the bdev-zone API:
bdev_nvme, bdev_ocssd, and vbdev_zone_block.

For all three modules, the number of zones can be calculated using:
block_count / zone_size.

To avoid this calculation being performed everywhere, create a helper
function in bdev_zone.h, together with the other zone APIs, such that
a user can easily get the number of zones.

77573e830e lib/bdev: ensure mutex is initialized
For correct behaviour, pthread_mutex should not be locked after it has
been destroyed.

g_bdev_mgr.mutex is statically initialized. It is destroyed in
bdev_mgr_unregister_cb, but not re-initialized in spdk_bdev_initialize.
Repeated calls to initialize/unregister occur during unit tests.
Remove the destroy from bdev_mgr_unregister_cb, which seems
the simplest way of resolving the issue.

The sequence: spdk_put_io_channel(), spdk_bdev_close(),
spdk_bdev_unregister() occurs during unit tests.
spdk_bdev_unregister() destroys internal.mutex which is then
locked by a call to bdev_channel_destroy() resulting from the
earlier spdk_put_io_channel(). Move the destroy and the free of
internal.qos into bdev_destroy_cb so that they don't occur until
all of the channels have been released. Remove the no longer
required bdev_fini.

Repeat calls to spdk_bdev_unregister that occur after an unregister has
completed will lock internal.mutex which has been destroyed by the
previous unregister. This occurs during unit tests. Defer locking
internal.mutex until after the internal.status has been checked for
SPDK_BDEV_STATUS_REMOVING. This is the only place where
internal.status is set to removing and g_bdev_mgr.mutex alone is
sufficient to ensure atomicity here.

Tested with a pthreads library that contains debugging code to
check the mutex state and a modified version of bdev_io_types_test
to call get_io_channel on a different thread.

e4070ee0e0 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

"bdev_register" notification was sent right when register
happened, which was misleading for any listener.
Action on the registered bdev might not have been possible
when examine took longer time.

Order of bdev_register notifications in json_config test
was modified, because they are being sent out as pollers
for the spdk_bdev_wait_for_examine() are being processed.
This is only because pollers are inserted at the tail,
and processed from the tail as well.

Order of notifications should not matter, as long as bdevs
are ready for use.

77b6f4bc3e lib/bdev: add spdk_bdev_wait_for_examine()
Add spdk_bdev_wait_for_examine() API to be called
in order to report when examine on all registered bdevs finished.
