60c8845fd0 bdev/ftl: construct_ftl_bdev respects default ftl config
Changed initialization of the ftl lib when using an rpc call to
allow for usage of any default configuration parameters (currently
only allow_open_bands is exposed).

dad4c43a88 vhost: add a single dpdk semaphore
The semaphore was a part of struct spdk_vhost_session_fn_ctx
so far, but since there's only one pthread waiting on that
semaphore and hence only one event using it, we could just
use a single global sem_t. Same thing with response code
for those callbacks - there's only one needed.

Going a step further, the function complete_session_event()
was removed - it would only operate on global variables now,
and its signature wouldn't make much sense after this
refactor, so it's been inlined.

This serves as cleanup.

ccdc0b615f vhost: operate on poll groups instead of lcores
With all the pieces in place we can finally remove
the legacy cross thread messages from vhost.

We replace spdk_vhost_allocate_reactor() with
spdk_vhost_get_poll_group(). The returned poll_group
has to be passed to spdk_vhost_session_send_event(),
where it will be assigned to the session. After the
session it started, that poll group will be used for
all the internal vhost cross-thread messaging.

f62d5ccbe6 nvme/tcp: Properly handle multiple iovecs in nvme_tcp_pdu_set_data_buf
nvme_tcp_pdu_set_data_buf() has been used to process C2H and H2C for
NVMe/TCP initiator.

In this case, NVMe/TCP cuts out the part of the input data buffer
and transfers the part, and repeats these cut and transfers until
the whole data buffer is transferred. NVMe/TCP uses two SGLs, and
use one to parse from the offset datao to datao + datal and another
to append from the offset 0 to datal.

However, the current nvme_tcp_pdu_set_data_buf() had used
data_length as not data length of this transfer but total length
of the whole transfers by mistake.

Recently DIF library updated to properly handle very similar
cases, and so this patch takes DIF library as a reference and
corrects the implementation.

The next patch will add UT code to verify the bug will be fixed.
The code size is pretty large and so UT code is separated.

a7b6d2ef00 nvme/tcp: Change parameters of nvme_tcp_pdu_set_data_buf to use in target
This patch is the first patch of the patch series.

The purpose of this patch series is to correct the bug of
nvme_tcp_pdu_set_data_buf() when the multiple iovecs array is
passed, to share nvme_tcp_pdu_set_data_buf() between NVMe/TCP
initiator and target, and utilize nvme_tcp_pdu_set_data_buf()
not only for C2H and H2C but also in-capsule data in NVMe/TCP
target.

This patch is necessary to satisfy the second requirement, to
share nvme_tcp_pdu_set_data_buf() between NVMe/TCP initiator and target
because struct nvme_tcp_req and struct spdk_nvmf_tcp_req are different.

Four variables, iov, iovcnt, data_offset, and data_len are common,
and hence this patch changes the parameters of nvme_tcp_pdu_set_data_buf()
to accept them.

The bug is fixed in the next patch and tested in after the next patch.

efd7b514d4 bdev: rewind child offset to last block size aligned iov
Here is the an example to describe existing issue:

There is a Write request with 64KiB data length, and this IO is cross the IO
boundary.  We assume that the parent IO will have 2 children requests, one is
33KiB length, the other one is 31KiB.  Here is the view of parent iovs, the
first 33KiB length data has 33 iovs:

iov.[0].iov_length = 1024;
.
.
iov.[31].iov_length = 256;
iov.[32].iov_length = 768;
.
.
iov.[64].iov_length = 1024;

In function _spdk_bdev_io_split(), then you can see that for the 33KiB length
child request, exiting code will run out of child child_iov space and return
error due to last one data buffer is not block size aligned.

Here we can rewind the existing offset to last block size aligned buffer to
avoid the error case, for backend which need aligned data buffer such as
AIO backend, the request will go through spdk_bdev_io_get_buf() again to
do the data copy, otherwise for those backend devices such as NVMe with
hardware SGL support, 256 data segment is fine for them.

cdc0170c1b nvmf/tcp: Add a maximal PDU loop number
In our previous code, we will handle all the PDU until there is
no incoming data from the network if we can continue the loop.
However this is not quite fair when we handling multiple connections
in a polling group.

And this change is setting a maximal NVME/TCP PDU we can handle
for each conneciton, it can improve the performance. After some
tuing, 32 should be a good loop number. Our iSCSI target uses
16.

The following shows some performance data:

Configuration:
1 Command used in the initiator side:
./examples/nvme/perf/perf -r 'trtype:TCP adrfam:IPv4 traddr:192.168.4.11 trsvcid:4420'
-q 128 -o 4096 -w randrw -M 50 -t 10

2 target side, export 4 malloc bdev in a same subsystem

Result:

c74ea9fa8e rocksdb: Fix null deref at blobfs calls
I tried experimental binding of SPDK with Mongo-rocks. However,
the binding sometimes invoke blobfs APIs without thread
initializations. In that case, null dereferences occur. In other
words, we need to carefully use blobfs not to invoke any threads
that are not registered to blobfs.

This patch simply adds a sanity check at every use of blobfs APIs.
By doing this, we do not need to care about which threads can use
blobfs APIs.

Put the locks inside cleanup_pci_devices().
This serves as cleanup.

fe511d03d2 env_dpdk/pci: reduce g_pci_mutex scope
The global pci tailq is no longer modified on the dpdk
thread, so on the spdk thread we can access it safely
without any lock. The code is slightly more readable
then.

This shows that cleanup_pci_devices() is always wrapped
with lock/unlock. We'll put the locks inside this
function in the next patch.

b941b2983a env_dpdk/pci: don't hotplug devices directly on the dpdk intr thread
To safely access the global pci device list on an spdk
thread, we'll need not to modify this list on any other
thread. When device gets hotplugged on a dpdk thread,
it will be now inserted into a new global tailq that
can be accessed only under g_pci_mutex. Then any
subsequently called public pci function will add it to
the regular device tailq.

cf0abd0e83 env_dpdk/pci: don't hotremove devices directly on the dpdk intr thread
To safely access the global pci device list on an spdk
thread, we'll need not to modify this list on any other
thread. When device gets hotremoved on a dpdk thread,
it will now set a new per-device `removed` flag. Then
any subsequently called public pci function will remove
it from the list.
