a6fe0806b3 iscsi: Update task->current_data_offset always when submitting subtask
Previously task->current_data_offset was updated by add_transfer_task().
However, the following patches will merge unsolicited data and solicited
data into a single subtask. It will be possible that add_transfer_task()
is called but subtask is not submitted. As a preparation, extract
updating task->current_data_offset into iscsi_pdu_payload_op_scsi_write().

395a8aea99 iscsi: Fix the case that incoming data is split between data segment and data digest
When data segment size is 64KB and data digest is enabled, if
data segment and data digest are split into different two packets,
- pdu->mobj[0] became full first when reading data semgment,
- pdu->mobj[1] was allocated but unused and data digest was read.

In this case, two SCSI write tasks were submitted by mistake and
the second SCSI write task had no data.

Fix the bug in this patch.

When iscsi_pdu_payload_read() is called and pdu->mobj[0] is full,
allocate pdu->mobj[1] only if any of data segment remains to read.

3ba1723a3a iscsi: Fix the case that incoming data is split into multiple packets
We had not considered a case that incoming data to the second data
buffer was split into multiple TCP packets when merging incoming data
up to 64KB.

We do not change the unit test because we already have data check
and it is very hard to include partial read into the data check.

However, it is very usual that incoming data is split into multple
TCP packets. The feature to merge incoming data up to 64KB will be
actually enabled in the following patches. So we rely on the I/O test
to verify this fix.

both nvme and nvmf library can use the API.

Also we should treat UINT8_MAX(255) as valid fabrics transport type.

54f28010a6 nvme/pcie: only set qpair state from qpair's thread
The qpair's state member is only 3 bits of a uint8_t,
and the in_completion_context bit is another bit in that
same uint8_t.

We know that the qpair's state is only ever updated by
one thread, but it is possible that the state could
be modified by one thread, while another thread
is modifying in_completion_context.

in_completion_context is only modified by the thread
that is polling the qpair (or the qpair's poll group).
But with async mode, another thread that has a qpair
on the same PCIe controller could poll its adminq and
reap the SQ completion for the qpair that's owned by
the other thread.

So do *not* set the generic qpair state to CONNECTED
from the SQ completion callback.  Instead just set
the pcie_state to READY, and let the thread that owns
the qpair detect the qpair is READY and set the state
to CONNECTED itself.

Fixes issue #2157.

ae8a1c5805 nvmf: Update controller desctruction process
There is a race condition between controller destruction and
subsystem state change, e.g. admin qpair may already be freed
when a namespace is added or removed. As result in function
poll_group_update_subsystem we may get heap-use-after-free error

Another problem is that some qpair's live time may exceed controller's
life time. To avoid it, start controller destruction process when the last
qpair finished the disconnect process (previously controller started
the descruction process before the last qpair starts to disconnect
and it could lead to raise conditions)

When intr mode is enabled, it will be common that
poller is unregistered during interrupt processing.
Since poller unregister is a delayed operation,
mark it in spdk_thread object, and reap unregistered
pollers out of poller execution.

db0a40f83a trace: enable adding relations between traces
Currently we do not have any way to connect traces from different
modules in SPDK. This change modifies our trace library
and app/trace to handle adding relations between trace points
and a trace object.

Additionally this patch adds classes and fields to structs
inside trace.py to prepare it for future patches implementing
printing relation information.

859230cdd1 event: use for_each_reactor to shut down reactors
There could be an outstanding for_each_reactor operation
in progress when the application shuts down.  If we don't
wait for that operation to complete, we'll get a memory
leak for its context.

So when stopping the reactors, before setting the
state to EXITING, do one final for_each_reactor to
ensure any outstanding for_each_reactor operations are
flushed.  Once this final for_each_reactor operation
is complete, we can set the state to EXITING safely.

Also use a global mutex and flag to ensure no more
for_each_reactor operations can start while the final
for_each_reactor is in progress.  If a new operation
is requested, we'll just ignore since the reactors are
shutting down anyways.

Fixes issue #2206.

0bd2b3654c accel: create SW Engine Channel if HW Engine not supports
Currently either HW Engine Channel or SW Engine Channel will be used.

In the case that HW Engine Channel is used while does not support related
operations like IOAT for CRC, it will shift back to the SW Engine's handle.

So that this is an issue that it still refers to the HW Engine Channel
while needs SW Eninge Channel to handle.

This patch introduces the SW Eninge Channel and always initializes there
in case that HW Engine does not support some operations.

Related UT also added to simulate the case the IOAT does not support CRC
and then SW Eninge needs to properly handle it.

To make such translation possible, update structure
spdk_memory_domain_translation_result to use a pointer

Add a single iov structure or cases where translation
is always 1:1, it will make easier translation callback
implementation. For RDMA transport translation of address
is always 1:1, so treat iovcnt other than 1 as an

spdk_get_io_channel() will be called during the getting
qpairs stream, which will add refcount value for each
existing channel. When end target, channel cannot be
destroyed since refcount be added additionally and
its value could not be subtracted to 0. As a result,
the program will hang in the process of exiting.

So here we don't need to allocate a new channel, just use
the exist one.

59b75da71e blob: use uint64_t for unmap and write_zeroes lba count
Previous patches (5363eb3c) tried to work around the
32-bit unmap and write_zeroes LBA counts by breaking
up larger operations into smaller chunks of max size
UINT32_MAX lba chunks.

But some SSDs may just ignore unmap operations that
are not aligned to full physical block boundaries -
and a UINT32_MAX lba unmap on a 512B logical /
4KiB physical SSD would not be aligned.  If the SSD
decided to ignore the unmap/deallocate (which it is
allowed to do according to NVMe spec), we could end
up with not unmapping *any* blocks.  Probably SSDs
should always be trying hard to unmap as many
blocks as possible, but let's not try to depend on
that in blobstore.

So one option would be to break them into chunks
close to UINT32_MAX which are still aligned to
4KiB boundaries.  But the better fix is to just
change the unmap and write_zeroes APIs to take
64-bit arguments, and then we can avoid the
chunking altogether.

Fixes issue #2190.
