14adf7f70f nvmf/tcp: unregister timeout poller in qpair_destroy
The timeout poller might still be registered when a qpair is destroyed
if we send C2HTermReq and then destroy the qpair before host terminates
the connection.

Fixes #2527

f0935084bd nvmf: set cid when failing a misordered fused command
If we don't set the cid before failing the misordered
command, we use some other random cid, causing the
initiator to think the wrong command was completed.

Fixes #2481.

For this issue, the target was completing a
previously submitted AER, not the fuzzed fused
command.  The initiator would then submit another
AER to replace the completed one, but the target
complained that the initiator sent too many AERs
since the target didn't really know it had completed
an AER so hadn't adjusted its num_aer count.

3056c8ac02 nvmf/tcp: delay qpair destruction
This patch adds an extra spdk_thread_send_msg() call to destroy a qpair
to make sure that it isn't freed from the context of a socket write
callback.  Otherwise, spdk_sock_close() won't abort pending requests,
causing their completions to be exected after the qpair is freed.

72925e3db8 nvmf/tcp: delay completion for zcopy reqs w/ in-progress writes
When a qpair is disconnected, any outstanding zero-copy requests are
freed to release their buffers before the qpair gets destroyed.
However, if there is a PDU being sent to the host as part of this
request (e.g. C2HData/R2T), we need to wait until that write is done
before freeing the request to avoid freeing it twice.

6301f8915d lib/sock: provide a hint to picking optimal poll group
The process of matching qpair to poll group is split into
two distinct parts that occur on different threads.
See spdk_nvmf_tgt_new_qpair().

This results in a race condition for TCP between spdk_sock_map_lookup()
and spdk_sock_map_insert(), which are called in spdk_nvmf_get_optimal_poll_group()
and spdk_nvmf_poll_group_add() respectively.

Fixes #2113

This patch picks a hint from nvmf_tcp for next poll group,
which is then passed down to spdk_sock_map_lookup().

When matching placement_id exists, but does not have
a poll group assigned - the hint will be used.

c81c10c529 nvmf/tcp: issue fused cmds consecutively to target layer
R2Ts can cause cmds to be submitted to the target
layer in a different order than they were received
from the host.  Normally this is fine, but not for
fused commands.

So track fused commands as they reach
nvmf_tcp_req_process().  If we find a pair of sequential
commands that don't have valid FUSED settings (i.e.
NONE/SECOND, FIRST/NONE, FIRST/FIRST), we mark the
requests as "fused_failed" and will later fail them
just before they would be normally sent to the target
layer.

When we do find a pair of valid fused commands (FIRST
followed by SECOND), we will wait until both are
READY_TO_EXECUTE, and then submit them to the target
layer consecutively.

This fixes issue #2428 for TCP transport.

794d47d4c4 nvmf/tcp: zero-copy support
This patch adds support for using zero-copy operations to execute IO
requests in the TCP transport.  Of course, they're only used if the
underlying bdev supports them.  Additionally, only requests with no
in-capsule-data can be executed using this mechanism.

Added several new states to accommodate for the difference in a way
zero-copy is handled.  Also, these flows very depending on the type of a
request (read or write).  It stems from zero-copy semantics: to perform
a write we need to wait for zcopy_end completion, while for reads
zcopy_end can only be submitted once we send all of the requested data
to the host.

d619f6c2cf nvmf/tcp: add round-robin poll group assignment for qpairs
When no optimal poll group exists for a qpair,
assignment for round robin happens in spdk_nvmf_tgt_new_qpair().

RDMA transport implments the logic for this assignment in
nvmf_rdma_get_optimal_poll_group().
TCP relied on the spdk_nvmf_tgt_new_qpair() instead.

This resulted in race condition when looking up and assigning
optimal poll groups - see #2113.

To remedy that, TCP now follows the same pattern as RDMA.
Next patch will improve the sock map lookup to fix the #2113.

If a response is returned prior to _nvmf_request_complete being called then the cid in the response is

expecting more data but none will be sent.  There are two cases where this can occur:
1) If the request is bi-directional
2) If nvmf_tcp_req_parse_sgl returns an error (e.g max_io_size exceeded)

e7f6ff2db6 Fix incorrect implementation of HPDA/CPDA in NVMe/TCP target code.
The current implementation treats HPDA/CPDA as the absolute offset
to the beginning of the PDU where the payload data starts. This is
incorrect. The HPDA/CPDA actually specify where the payload data
should start such that the starting location is a multiple of HPDA
(for C2H PDU) or CPDA (for H2C PDU or CapsuleCmd PDU).

The other issue fixed is that the current implementation calculates
padding only when header digest is enabled. This is also incorrect.

Socket request has iov vector of limited size and when
DIF insert of strip feature is enabled we send each data
block as separate iov element to remove metadata.
In the case of large read operation there might be not
enough iov elements to describe all data block. In this
case we can send several C2H PDUs.
To estimate the number of bytes that can be written
with single C2H we try to fill socket iovs. That is
not so cheap operation so this fix is implemented
for DIF case only. Also data buffers in regular
read operation should always fit into socket iov
vector.
