c5e5047d99 iscsi: Manage PG-IG maps of the target by linked list
This patch is a preparation for dynamic reconfiguration of PG-IG maps.

Current PG-IG map is implemented by a fixed-size array. Linked list
will make much easier to support dynamic reconfiguration of PG-IG maps.

Current:
target - (1..n) ---> PG_map (1..1) -> PG
                 |
                 --> IG_map (1..1) -> IG

This proposal:
target - (1..n) -> PG_map --- (1..1) -> PG
                           |
                           -- (1..m) -> IG_map - (1..1) -> IG

d12ba75bd1 blob: add per-blob feature flags
Similar flags will be added at the blobstore level in a future
patch.

This allows backwards compatibility - i.e. allow older blobstore
applications to open blobstores created by newer blobstore
applications with new features.  Any blob's using a new feature
should have an associated flag set in one of three new flag masks:

- invalid: if a bit is set in this mask that the application is not
	   aware of, do not allow the blob to be opened
- data_ro: if a bit is set in this mask that the application is not
	   aware of, allow the blob to be opened, but do not allow
	   write I/O nor any operation that changes metadata
- md_ro:   if a bit is set in this mask that the application is not
	   aware of, allow the blob to be opened for performing any
	   kind of I/O, but do not allow any operation that changes
	   metadata

While here, bump SPDK_BS_VERSION to 3.  We intend this to be the
last change made to SPDK_BS_VERSION - future versioning will be
done via blobstore or per-blob feature flags instead.

c2f38258f9 iscsi: Remove redundant repetition from ACL
The results of access control procedure for login in the
spdk_iscsi_tgt_node_access() is defined in the following table:

   +------------------------------+
   |iscsi name |netmask  |result  |
   +------------------------------+
   +------------------------------+
   |denied     |-        |denied  |
   +------------------------------+
   |allowed    |allowed  |allowed |
   +------------------------------+
   |allowed    |denied   |next IG |
   +------------------------------+
   |not found  |-        |next IG |
   +------------------------------+

However current implementation have redundant repetition in the
spdk_iscsi_tgt_node_access() and the above definition is not
visible. Hence refactor spdk_iscsi_tgt_node_access().

Besides refactor spdk_iscsi_tgt_node_allow_iscsi_name() because
it has redundant repetition too.

Add UT code for these changes.

Hence "ANY" will be better than "ALL" and will avoid misunderstanding.

Comments and iscsi_tgt test code are also changed and UT code is added.

later if necessary without breaking API.

c24340a588 rte_virtio: remove unused static variable 'm'
The 'm' variable was only used in sizeof expressions; m was a struct
vhost_user_msg, and we already have one of those called 'msg' in the
function where it was needed.

A previous commit removed a RTE_USED() marking on m, which introduced a
warning on clang, since it can now see that m is unused.

Fixes: 73bfcede86 ("rte_virtio: remove rte_memzone from vq")

f2223d7d21 blob: add data_ro and md_ro flags to spdk_blob
data_ro means that write, write_zeroes and unmap operations are not
allowed.

md_ro means that resize, set_xattr and remove_xattr are not
allowed.

There is no code yet that can activate this - it is coming in a future
patch.  Two usages are planned though:

1) a user explicitly marks a blob as read-only - this is persisted so that
   future loads of the blob will ensure the blob cannot be modified - neither
   metadata nor data
2) a future feature flag framework (how's that for alliteration) may allow
   a blob to be opened, but not allow metadata modifications, if there are
   feature flags set in the blob's or blobstore's metadata that the
   application does not understand

During testing it was shown that VPP interprets only

When here, more descriptive error logs were set in case of
failure.

7e0951d7f5 bdev_virtio: ensure thread safety for virtio_dev unregister
The io_device_unregister callback might be
deferred and called on a different core, but
the virtio device has to be released from
the same thread that created it. Hence, once
the unregister callback is called, it has
to send yet another msg to the vdev-owning
thread. Since all virtio devices are currently
created on the same thread, no mutexes are
needed. They will need to be introduced once
we publish the API to connect to virtio
controllers.

This patch also defers bdev_virtio module-
-finish until all virtio_devs are destroyed.

1517ed376d nbd: put all fds in spdk_nbd_disk
dev_fd => fd for /dev/nbdX device node
spdk_sp_fd => fd that SPDK will use to poll for new
		I/O requests from the kernel nbd thread
kernel_sp_fd => fd passed to the kernel to send I/O
		to SPDK

This enables an upcoming patch to switch from using
fork() to pthread_create().

4df5329092 iscsi: stop using "OK/NG" for comments in ACL
"OK/NG" may be only used in Japan. It may cause misunderstanding.
Hence remove "OK/NG" or change to "Allowed/Denied".

Access control of iSCSI target follows further refactoring.
Hence to save the amount of change, "OK/NG"s are mainly removed.

9daed64edb rte_virtio/user: removed virtio_user_dev.h
It's contents have been moved to
virtio_user/vhost.h and virtio_dev.h.
The virtio_user_dev struct can't be hidden
in virtio_user.c (similarly to the virtio_hw),
due to another abstraction layer in virtio_user
- vhost-user and vhost-kernel. Even though only
vhost-user is implemented now, let's not close
the possibility to implement vhost-kernel in
the future. The vhost-user/vhost-kernel code
should probably be placed in separate files,
with the virtio_user_dev struct in common
vhost.h header.

of the vtpci layer from rte_virtio.

virtio_dev_construct and virtio_dev_init
functions. construct would just allocate
and setup the struct data. init would
be the one to start the device via
MMIO/vhost-user. virtio_dev_construct
takes 2 params - backend ops and backend
context. The context is kept as void*
and can be cast to proper structs inside
backend ops callbacks.

5fa2274ccb io_channel: change return type of spdk_channel_msg
Change the return type of spdk_channel_msg from
void to int. If this msg executed in a failure,
we do not need continue sending the message to other
threads, we can just tell the original thread, and
let the orgiginal thread call the spdk_channel_for_each_cpl
call back.

Thus we can track the qpair creation/destroy case for bdev
reset in nvme bdev module;

4927c20681 iscsi: Treat unregistering pollers as a synchronous operation
We always unregister pollers from the core they're running on,
so we don't need the async completion event when unregistering
them. To avoid changing the logic, create events instead.

ed53cba059 nvme: normalize PCI addresses before comparing
Use the env abstraction PCI functions to compare PCI addresses so that
details like whether or not domain is specified or whether 0-padding is
present don't affect the comparison.

For example, 0000:01:00.0 should compare equal to 01:00.0.
