While here, also allocate g_null_read_buf using

When the specified buffer size to spdk_bdev_io_get_buf() is greater
than the permitted maximum, spdk_bdev_io_get_buf() asserts simply and
doesn't call the specified callback function.
SPDK SCSI library doesn't allocate read buffer and specifies
expected read buffer size, and expects that it is allocated by
spdk_bdev_io_get_buf().
Bdev perf tool also doesn't allocate read buffer and specifies
expected read buffer size, and expects that it is allocated by
spdk_bdev_io_get_buf().
When we support DIF insert and strip in iSCSI target, the read
buffer size iSCSI initiator requests and the read buffer size iSCSI target
requests will become different.
Even after that, iSCSI initiator and iSCSI target will negotiate correctly
not to cause buffer overflow in spdk_bdev_io_get_buf(), but if iSCSI
initiator ignores the result of negotiation, iSCSI initiator can request
read buffer size larger than the permitted maximum, and can cause
failure in iSCSI target. This is very flagile and should be avoided.
This patch do the following
- Add the completion status of spdk_bdev_io_get_buf() to
spdk_bdev_io_get_buf_cb(),
- spdk_bdev_io_get_buf() calls spdk_bdev_io_get_buf_cb() by setting
success to false, and return.
- spdk_bdev_io_get_buf_cb() in each bdev module calls assert if success
is false.
Subsequent patches will process the case that success is false
in spdk_bdev_io_get_buf_cb().

It seems like DPDK 19.02 has split the "session mempool"
into two separate mempools but this isn't really described
in the DPDK release notes, so this patch only makes our
crypto code behave just like DPDK crypto examples.
rte_cryptodev_queue_pair_setup() no longer accepts
a separate mempool parameter but instead requires it
to be passed through a new field in struct
rte_cryptodev_qp_conf, which is also passed as a param
to rte_cryptodev_queue_pair_setup(). It's referred to as
"session private mempool" instead of "session mempool",
which makes some sense since we already use
rte_cryptodev_sym_get_private_session_size() (with the
word "private" in name) to calculate its size.
The other mempool - "session mempool" - now has to be
allocated with rte_cryptodev_sym_session_pool_create()
instead of regular rte_mempool_create().

Allow user to add seed value for guard compuation to DIF context.
This will avoid the guard being zero in case of all zero data.
NVMe controller doesn't support seed value for guard computation
explicitly, and hence if we want to use such a seed value in
NVMe controller, we have to format metadata more than 8 byte,
and add seed value into the reserved metadata field.
But some popular iSCSI/FC HBAs and SAS controllers have supported
seed value for guard computation, and so supporting seed value
in the SPDK DIF library is very helpful for some use cases.
Hence this patch makes the DIF library possible to specify seed
value for those use cases.

Typically, this is not a problem as these functions are not called directly
rather, they are only used as constructor functions to load the bdevs during
system startup.
There are languages however, (e.g rust) that require these functions to be

In order to reference them, having the names predictable (and potentially

This function gets used as a function pointer, which
seems to keep the compiler from trying to inline the
function. Stack manipulation was showing up in the
perf profile pointing to this. Marking the function
as inline gets it actually inlined in the hot I/O
path.

Besides, the caller of bdev_ftl_init_bdev() (e.g.

return errno.

After passing the check of protective mbr, there is a high probability that

table and try to get partition info from it. When parsing secondary table
successfully, add a warning log to notify users that primary table is broken.

Modify existing code of parsing primary partition table to support parsing
the secondary.
Main difference of these two tables is that they have inverse buffer layout.
For primary table, header is in front of partition entries. And for secondary
table, header is after partition entries. So add helper functions to extract
header and partition entries buffer region from primary or secondary table
based on current parse phase.
Split the exported funtion spdk_gpt_parse into two functions spdk_gpt_parse_mbr
and spdk_gpt_parse_partition_table. So spdk_gpt_parse_partition_table could be
used to parse both primary and secondary table.

This RPC doesn't really work in some cases - for example,
trying to delete one NVMe namespace bdev from a controller
with multiple namespaces, or just one virtio SCSI device
from a virtio-scsi controller. We've previously kept it
and marked it as "debugging only" - but every bdev module
has its own RPC method now for deleting what it constructed,
so keeping the generic delete_bdev RPC is asking for
trouble in some of the cases mentioned above. We'll remove
it in the 19.04 release.
