cdf80adccc nvmf/fc: Check if buffer came from pool prior to nvmf_fc_request_free_buffers()
NVMe-oF FC transport have used its own buffer pool and have not used
common buffer pool yet.

It looks that there is no particular reason to prevent FC transport
from using the common buffer pool.

This patch extract checking fc_req->data_from_pool from
nvmf_fc_request_free_buffers() to make the transition easier.

fc_req->req.iovcnt and fc_req->req.data should be cleared regardless
of fc_req->data_from_pool. Hence extract them into callees.

cbd3500019 nvmf/fc: Use common setting to FC specific data buffer pool
NVMe-oF FC transport have used its own buffer pool and have not used
common buffer pool yet.

It looks that there is no particular reason to prevent FC transport
from using the common buffer pool.

This patch adjust the setting of the FC transport specific buffer pool
to the common buffer pool to make the transition easier.

Large alignment requirement consumes more memory but is acceptable.
Cache size calculation looks dated.

32e22643ef nvme: add NVME_QUIRK_DELAY_BEFORE_INIT quirk
Currently we *always* wait 2 seconds before starting
controller initialization during attach.  This
works around an issue where some older Intel NVMe SSDs
could not handle MMIO writes too soon after a PCIe
FLR (which would be triggered when VFIO was enabled).

After further discussion with Intel experts, we know
the SSD models that exhibit this issue.  So we can
quirk this so that only the older SSDs incur the extra
delay.

d1d69a169c vhost: remove session type checks
When rte_vhost tells us to start a session with given
vid, we lookup the corresponsing session object from
an spdk-internal session list and tell it to start
polling without even specifying any backend. The vsession->vdev->type
checks could only fail as a result of some spdk data
corruption, so replace those with just asserts now. This
code path could have never been hit in our tests anyway.

e5d7a44581 vhost: introduce session names
We currently don't have any way to differentiate different
sessions e.g. in error messages. Whenever there's an error
in some session, we just print the device name.

We now introduce vsession->name with the following format:
<device name>s<dpdk connection id>

Note that it's still impossible to know exactly which
qemu process corresponds to which session in spdk, but
there's not much we could do in that matter right now.
In spdk we don't even have the accepted connection fd.

3b6f69c8f5 vhost: remove unnecessary membarrier on I/O completion
We've recently switched from manually calling eventfd_write()
to rte_vhost_vring_call(), which besides writing to the
eventfd, always calls a full memory barrier in the upstream
rte_vhost lib. With upstream rte_vhost we're actually
calling two memory barriers on I/O completion - one in
spdk code, one inside rte_vhost_vring_call().

The spdk barrier was only required for our internal rte_vhost
lib, whose rte_vhost_vring_call() implementation (that we
wrote) did not have such membarrier inside. So now we'll
add this membarrier there, and remove the same barrier
from spdk code.

This doesn't change any code flow for the internal rte_vhost
lib, but optimizes I/O path for the upstream version.

703a5473f7 iscsi: Restore the previous bug fix for LUN hot plug
One recent commit destroyed the critical bug fix for LUN hot plug.
Hence this patch restores the critical bug fix. Simple revert is
not possible because connections are assigned to poll groups
instead of cores now. But we can revert easily because earlier
version of the recent patch did that.

Fixes #925

The github issue was caused by commit 8cf1945432.
The bug fix restored by this patch is commit 1f6a78620d.
The reference we can follow to create this patch is earlier version
of commit fb641c4b54.

f8433aad23 rpc/nvmf: add tgt_name options to relevant RPCs.
All of the RPCs in lib/nvmf/nvmf_rpc.c rely on knowing which nvmf_tgt
they should work with. They have historically relied on the assumption
that there will only be a single target in a given application. This is
true for the example application in the spdk repo, but it is not
necessarily true generally,

By adding an option tgt_name parameter to the RPCs we enable them for
multi-target NVMe-oF applications. We also further reduce the coupling
between the library and the example application.

As part of moving the nvmf rpc code to the library, we will need to make
it more inclusive of use cases outside of the example spdk nvmf_tgt
application. That application only supports a single nvmf target
structure. As such, many of the RPCs have this assumption built into
them.
In order to enable the multi-target use case, we need to configure a way
to translate between user supplied RPCs and actual target objects in the
library.

2226750a7c nvme: add an option 'no_shn_notification' to driver
spdk_nvme_detach() will do the normal shutdown notification for
most cases, and it will take some time e.g. 2 seconds to finish
the process for PCIe based controllers.  If users' environment
has several drives, each drive will call spdk_nvme_detach() one
by one, and the shutdown process may take very long time.

Since users know exactly what they would like to do for the next
step, so here we provide an option to users, users can enable it
to skip the shutdown notification process so that they can have
very quick shutdown process, and when starting next time, the
controller can be enabled again.

When building shared libs, we specifically don't set the --as-needed
flag so that we still link against libraries that have constructor
functions. LD reports on its man page that the default behavior is
equivalent to --no-as-needed.

For RHEL based distros like fedora and centos this works fine. While
the LD man page shipped with ubuntu distributions also states that
--no-as-needed is the default, they don't respect that behavior and do
--as-needed linking unless you force them with --no-as-needed.

fb641c4b54 iscsi: Assign connections to poll groups instead of lcores.
This patch binds poll groups to SPDK thread through IO channel and
assigns connections to poll groups instead of cores.

iSCSI subsystem registers iSCSI global object as an IO device, and create
poll groups as context of IO channels of the IO device.

Each portal get and hold portal group on which the corresponding acceptor is
running.

When a connection is constructed, iSCSI subsystem assigns a poll group
to the connection by getting it from the corresponding portal.

When a connection enters full-feature phase, iSCSI subsystem schedules
the connection to a poll group by round-robin.

Then, each connection can know its running SPDK thread directly and can
use SPDK message passing infrastructure instead of SPDK event framework.

By this change, iSCSI connections are binded to SPDK thread, and not
binded to processor core anymore.

Some other changes in this patch are
- core ID is removed from the output of get_iscsi_connections RPC. The
  upcoming patches will change the RPC to use spdk_for_each_channel and can
  access SPDK thread safely, and add SPDK thread ID instead.
- utilize UT multithread framework added by the last patch to test
  iSCSI poll groups by UT.

284aca9e36 bdev/raid: Fix race issue among multiple threads to free RAID bdev
The following issue was observed.

The first thread returned the last IO channel and the second thread
then removed the first base device, but raid_bdev_cleanup() was
called before raid_bdev_destroy_cb() was called.

raid_bdev_destroy_cb() was accessed to the raid bdev already freed
by raid_bdev_cleanup() and caused segmentation fault.

The call sequence was as follows:

The first thread:
 spdk_put_io_channel() -> ch->destroy_cb -> raid_bdev_destroy_cb
-> access raid bdev

The second thread:
 raid_bdev_remove_base_devices() -> raid_bdev_deconfigure() ->
spdk_bdev_unregister() -> spdk_io_device_unregister() ->
spdk_bdev_destroy_cb() -> raid_bdev_destruct() -> raid_bdev_cleanup()
-> free raid bdev

The fix is to hold number of created channels in struct
raid_bdev_io_channel and use it in raid_bdev_destroy_cb().

Bdev layer, IO device/channel layer, and NVMe-oF layer  already
process this case correctly.

    Fixes #884.

7cbe1ccd56 nvme: move SPDK_NVME_DEFAULT_RETRY_COUNT out from nvme.h
SPDK_NVME_DEFAULT_RETRY_COUNT is the default value for each controller, so
we can move it out from public header file, and change the value if users
provide a new one.

"NvmeRetryCount" was deprecated for a long time, so we removed the support
for this configuration option as well.

8cf1945432 iscsi: Hot remove callback closes LUN directly without using event call
This patch is in the patch series to migrate iSCSI connection management
from core based to SPDK thread based.

The callback to hot removal of LUN, iscsi_conn_remove_lun, is called
on the same core when the corresponding LUN is opened. Additionally,
all operations in iscsi_conn_remove_lun are completed synchronously.

Hence inline _iscsi_conn_remove_lun into iscsi_conn_remove_lun.
Add assert to check the function is called on the specified core.

This change is helpful to achieve the goal of the patch series
because spdk_event can have two parameters but spdk_msg can have
only a single variable, and hence we cannot convert simply and have
to introduce a context allocated dynamically otherwise.

4640f32482 Make: conditionally build the event_vhost library
This library was being consistently built, even when the CONFIG_VHOST
directory was set to false. On the shared object build, this leads to a
few undefined references from the event_vhost.so library when trying to
link against an SPDK application.

This library should be built based on the same conditions as the vhost
library. This assumption is already baked into other aspects of the
build system. See for example the makefile under app/spdk_tgt.

For aarch64 spdk_mb is defined as "__asm volatile("dsb sy" ::: "memory")"
and spdk_smp_mb is defined as "__asm volatile("dmb ish" ::: "memory")".
"dsb sy" completes when all instructions before this instruction complete.
And "dmb ish" only keeps the order of memory access instructions before
and after it. It doesn't affect the ordering of any other instructions.
Here I think "dmb ish" is enough.

And replace spdk_mb with spdk_smp_mb here will not affect PPC64, X86_64

c9c80e6932 nvmf/rpc: Fix io channel reference counting in NVMf statistics
NVMf statistics functions use spdk_get_io_channel function to get a
poll group. It increases reference counter in io channel and causes
problems on application exit. spdk_put_io_channel calls were added to
release the channel.

5de38f9543 bdev/compress: update some defines for QAT
There's a small drive-by in here also, use the max iovec define
from the reduce header instead of manually making sure its the same
here.

The change in the size of the MBUF pool is to accommodate the new
QAT driver being faster (?) than the old such that we could run out
of MBUFS with a fio test using 6 threads.  On the + side, when we did
the queueing code in the compression operation worked good.

Also related to QAT and experimenting with fio compression ratios, QAT
can fairly often return an error on compression that we were treating
as an error for printing, change it to a NOTCELOG instead of an error.

6d4f580e79 nvmf/tcp: Remove spdk_nvmf_tcp_qpair_process_pending
Phenomenon:
Test case:  Using the following command to test
./test/nvmf/target/shutdown.sh --iso --transport=tcp
without this patch, it will cause coredump.
The error is that the NVMe/TCP request in data buffer
waiting list has "FREE" state.

We do not need call this function in
spdk_nvmf_tcp_qpair_flush_pdus_internal, it causes the
bug during shutdown test since it will call the function
recursively, and it does not work for the shutdown path.

There are two possible recursive calls:

(1)spdk_nvmf_tcp_qpair_flush_pdus_internal ->
spdk_nvmf_tcp_qpair_process_pending ->
spdk_nvmf_tcp_qpair_flush_pdus_internal ->
>..
(2) spdk_nvmf_tcp_qpair_flush_pdus_internal->
pdu completion (pdu->cb)
->..
-> spdk_nvmf_tcp_qpair_flush_pdus_internal.

And we need to move the processing for NVMe/TCP requests
which are waiting buffer in another function to handle
in order to avoid the complicated possbile recursive
function calls. (Previously, we found the simliar
issue in spdk_nvmf_tcp_qpair_flush_pdus_internal for
pdu sending handling)

But we cannot remove this feature,
otherwise, the initiator will hang for waiting the
I/O. So we add the same functionality in spdk_nvmf_tcp_poll_group_poll
function.

Purpose: To fix the NVMe/TCP shutdown issue.
And this patch also reables the test for shutdown and bdevio.

threads that the bdev module will support
* changing the qp assignment code such that comp_bdevs share the

59339feac3 jsonrpc: tolerate null json value for parameters in json-rpc call
Rust lang has notion of empty value `()` which is translated to json null
value using serialization library like serde. Thus it means that jsonrpc
methods having no parameters translate to parameters with null value (as
opposed to a request without parameter member as it is done now in spdk).
This change handles null parameter gracefully instead of returning an
error - improving interoperability with such clients.

9307ff5a54 net/vpp: move to VPP 19.04
This patch updates net/vpp implementation from version VPP 19.01 to
VPP 19.04.

1. Some binary APIs are deprecated in 19.04 and message queue is used
   to handle control events:

   - vl_api_bind_sock_reply_t_handler by SESSION_CTRL_EVT_BOUND,
   - vl_api_unbind_sock_reply_t_handler by SESSION_CTRL_EVT_UNLISTEN_REPLY,
   - vl_api_accept_session_t_handler by SESSION_CTRL_EVT_ACCEPTED,
   - vl_api_connect_session_reply_t_handler by SESSION_CTRL_EVT_CONNECTED,
   - vl_api_disconnect_session_t_handler by SESSION_CTRL_EVT_DISCONNECTED,
   - vl_api_reset_session_t_handler by SESSION_CTRL_EVT_RESET

2. Fixes for Fedora 29/30:

   - added "-Wno-address-of-packed-member" (DPDK 19.02 fails to compile
     with gcc9.1),
   - force "-maes" compile flag for gcc9.1 to compile crypto_ia32 and
     crypto_ipsecmb plugins (gcc9.1 doesn't do that for -march=silvermont)
   - some minor fixes

3. Default path for VPP instalation is changed for test scripts from
   /usr/local/src/vpp to /usr/local/src/vpp-19.04 to avoid VPP version
   conflict.

4d9faf7c6b lib/ftl: Add check if device is halted during reloc
It's possible there's a delay between spdk_ftl_dev_free setting
dev->halt and sending message to core thread which would set
reloc->halt. This patch should bridge this gap and prevent potential
additional/unneeded relocations from happening.

0242a80793 lib/reduce: fix problem with size of chunk map area in PMEM
This fixes a segfault found by using a very small logical volume.
The PMEM file chunk map area wasn't including the chunk map struct
itself.  In PMEM, a single entry as returned by _reduce_vol_get_chunk_map()
is made up of a 'struct spdk_reduce_chunk_map' plus one uint64_t for
each backing IO unit for the volume (# depends on vol parms). So when
an app got close to the end of the chunk map indices it would run off
the end of PMEM and segfault.

With this fix that no longer happens however data integrity issues now
show up with fio. I believe this fix is valid though and am pursuing the data
integrity issue as something new.

eb1ddcb664 lib/reduce: remove dead code clearing unused backing io units
At the start of time all of values of io_unit_index[] array in
the chunk maps are FF's.  When a partial chunk is written, only
some of the io_unit_index[] vals will be assigned values from the
allocated_backing_io_units bit array.  When that chunk is written
again, it is not done so in place and at that time in when
_write_write_done() is called, the io_unit_index[] values are
set to FF again and the bit array bits are cleared for the old
chunk so that it is fresh again for use by another write.

This change removes code from an early stage of the write process
where a 'fresh' chuck in allocated.  Because of points made earlier,
it is not possible for any of the io_unit_index[] values to be
assigned or have a corresponding bit set in the bit array.

The prev version of this patch cleared the bit array because the
io_unit_index[] array was being cleared however after further
investigation, and for the reasons stated earlier, the io_unit_index[]
did not have a valid value so clearing the bit array was simply wrong.

Removing this dead code clears things up and leaves it to one place
to clear the io_unit_index[], when a chunk is overwritten.  Well, 2
places including init time.

Scan-build will then complain:

blobstore.c:1151:10: warning: Use of memory after it is freed
                assert(ctx->blob->active.clusters[0] != 14213);

Asserting blob == ctx->blob, blob->active.clusters == ctx->...,
or even tmp != blob->active.clusters doesn't work, so use the
last resort scan-build weapon - #ifdef __clang_analyzer__.

The realloc in this case is just down-sizing a buffer to
save some memory. For scan-build, just don't do it. This
finally silences all scan-build false positives.

Func spdk_nvmf_rdma_destroy_defunct_qpair is a "last chance option"

There's a probability that ibv_poll_cq polls wr of the destoryed qp

practice the risk of this situation is minimal(if not non-existent),
add a log here so that we could detect this situation easily.

a3c78e150b lib/ftl: Remove separate dma_buf allocation in band
Since 4k alignment is no longer required for I/O buffers, the
band doesn't need a separate lba map and dma buffer and can use the
same memory location.

a4b3481242 lib/ftl: Remove buffer alignment requirements
Ftl should no longer require 4k alignment for I/O buffers for either
internal or external requests. The 4k alignment was needed due
to a bug in QEMU when handling internal SGL buffers in LNVM commands.

1897943987 env: define minimum alignment for dma-able memory
DPDK defines the minimum alignment as "suitable for any
kind of variable (in the same manner as malloc())", but
internally the alignment is always rounded up to the
cache line size, even if the requested alignment is 0.

We would like to start relying on this behavior in FTL,
where lba maps are allocated using DMA-able memory and
are constantly looked up or modified by different threads.
By having the lba maps unaligned, we risk having those
threads pollute each other's cache lines.

Rather than enforcing this memory alignment in FTL, we
do it in spdk_*malloc directly. In general it makes
sense to have DMA-able memory always cache-line-size
aligned for the same reason as above.

96b759297f lib/bdev: fix coredump when bdev initialize failed.
If subsystem bdev module initialize failed, it will call
spdk_bdev_init_complete(-1) -> (subsystem bdev)->fini
_spdk_bdev_finish_unregister_bdevs_iter -> spdk_bdev_module_finish_iter

In abovt path, spdk_bdev_module_finish_iter will repeate to call
bdev_module->module_fini function. Some bdevs will call spdk_io_device_unregister
which never call spdk_io_device_register. It will coredump when assert false in
spdk_io_device_unregister dev is null.

To fix this, let's check whether g_bdev_mgr.module_init_complete is equals true
and then call the bdev_module->module_fini.

3fb1a9565e vhost: finish foreach_session chain always on the init thread
foreach_session() is used to e.g. close a bdev, where
for each session we close any io_channels and then,
on the final "finish" call, close the bdev descriptor.

The vhost init thread is the one that called
spdk_vhost_init() and also the same one that calls
all management APIs. One of those is for hotplugging
LUNs to vhost scsi targets, which practically results
in opening bdev descriptors.

By always scheduling that final foreach_session()
callback to the init thread, we end up with calling
spdk_bdev_close() always on the same thread which
called spdk_bdev_open(), which is actually a bdev
layer requirement.

4b60bd1b59 vhost: don't setup session coalescing on vdev init
We used to call potentially-asynchronous foreach_session()
in vdev initialization path and that was perfectly
fine because at that time there were no sessions created
and foreach_session() was always finishing synchronously.
We're about to refactor it to be always asynchronous, and
for this coalescing case it could complicate the init
error path. Once asynchronous thread msg is sent, we would
need to wait for it to complete and we just don't want to
do that. We want error handling to be simple.

Since we know there are no sessions at the time of vdev
creation, we just add a new function for setting coalescing
params just for vdev (and not for its sessions) and we
use that function in vdev init code.

By making dpdk device detach asynchronous we have
actually broken some cases where devices are re-attached
immediately after and fail since they were not detached
yet, so now we're making device detach synchronous again.

For that we'll simply wait inside spdk_pci_device_detach()
for the background dpdk thread to perform all necessary
actions before we return. We'll also print an error msg
if DPDK failed the detach (probably because of some
internal error).

79b5618168 env_dpdk/pci: don't defer device detach while on the dpdk thread
By making dpdk device detach asynchronous we have
actually broken some cases where devices are re-attached
immediately after and fail since they were not detached
yet.

We'll need to make detach synchronous again, and for that
we'll wait for the background dpdk thread to perform all
necessary actions before we return from spdk_pci_device_detach().

However, device detach could be triggered from the very
same dpdk background thread as well. Waiting there would
cause a deadlock, so now we'll schedule asynchronous
device detach to the dpdk thread only if we're not on
that thread already.

This patch itself serves also as an optimization.

5acf617c6e nvme: add functions to pretty-print commands and completions
This change attempts to address the Trello request to decode I/O errors in
NVMe hello_world example.

See https://trello.com/c/MzJJw7hM/2-decode-io-errors-in-nvme-helloworld-example

As part of this change, spdk_nvme_cpl_get_status_string was declared
in nvme.h, and spdk_nvme_qpair_print_command and
spdk_nvme_qpair_print_completion were renamed and added to nvme.h,
allowing all three to used "externally."

To test the failing paths, two compile time defines were added to force a
write or read error (bad LBA) respectively.

As the example does a read after write, if the write fails, the example fails.

0f0af48009 lib/ftl: keep reloc traffic out of non-volatile cache
Moving data from one band to the other doesn't need to be stored on the
non-volatile cache. Not only does it add unnecessary traffic to the
cache (wearing it out and reducing its throughput), but it requires us
to synchronize it with user writes to the same LBAs.

To avoid all that, this patch adds the FTL_IO_BYPASS_CACHE flag to all
writes coming from the reloc module. However, to be sure that the moved
data is stored on disk and can be restored in case of power loss, we
need to make sure that each free band have all of its data moved to a
closed band before it can be erased. It's done by keeping track of the
number of outstanding IOs moving data from particular band
(num_reloc_blocks), as well as the number of open bands that contains
data from this band (num_reloc_bands). Only when both of these are at
zero and the band has zero valid blocks it can be erased.

This patch adds tracking of the phase of the writes to the non-volatile
cache. The phase is changed each time the whole buffer is filled. Along
with every block's LBA, current phase is stored in its metadata. This
allows for replaying the sequence of writes when recovering the data
from the cache after (unclean) shutdown.

Since there are only three possible phases to be stored on the device at
a time, phase is defined as a 2-bit counter cycling through 1 -> 2 -> 3
-> 1, with 0 marking blocks that were never written.

6b654ab900 bdev: prevent early spdk_bdev_init_complete()
In case some module has `async_init = true` and
  some other module that comes after it fails to initialize,
  then callback from asynchronously initialized module
  may call `spdk_bdev_init_complete()` first, then failed module
  will call `spdk_bdev_init_complete()` later.
  This currently results in NULL dereference because
  first call to `spdk_bdev_init_complete()` sets `g_init_cb_fn = NULL`.

This change prevents first call to `spdk_bdev_init_complete()`
  by saying that failed module is not finished with initialization.

This patch fixes #847

0b3fb2403e lib/reduce: fix bug with adding up req->decomp_iovcnt
In the memcpy elimination patches, the same bug exists in 3
places.  When building req->decomp_iov using the host buffers,
req->decomp_iovcnt was being incremented in the loop and also
being used as part of the index messing everything up.

b9bc6254a8 lib/reduce: fix critical issue with reduce optimization
The first optimization to eliminate memcpy was too aggressive and
did so for the read-modify-write operation as well. This didn't
affect the fio tests used that the time but bdevio catches it
right away.  When over writing a chunk with data, we first need
to read the old data before applying the new. This patch uses
the scratch buffer for old data as sending it to the user buffer
results in it not being written at the end of the read-modify-write.

There is at least one more bug fix coming after this also found
with bdevio but passed with fio

b860c8dbce bdev/gpt: call get buffer function before forwarding read I/O to the base bdev
iSCSI target does not allocate data buffer on read, and delegate
allocation to the bdev.

When the bdev is a split vbdev, the split vbdev does not allocate
data buffer and delegate allocation to the backend bdev.

In this case, iSCSI target expects the buffer is allocated until
notifying completion to the split vbdev. However, the split vbdev
notifies completion to the backend bdev when calling the callback
of iSCSI target. The backend bdev frees the buffer immediately,
but iSCSI target still uses the buffer. If the buffer is reused
by another I/O, data corruption will occur.

For this issue, vbdev_gpt_submti_request() calls
spdk_bdev_io_get_buf() when the I/O is read, and its callback
vbdev_gpt_get_buf_cb calls _vbdev_gpt_submit_request() then.

This will ensure the buffer is allocated before forwarding I/O
to the backed bdev.
