nvme: add I/O characteristics fields

2019-07-09T21:15:37+00:00

Several new fields have been introduced in version 1.4 of the NVMe spec
at offsets that were defined as reserved in version 1.3d of the NVMe
spec. Update the definition of the nvme_id_ns data structure such that
it is in sync with version 1.4 of the NVMe spec. This change preserves
backwards compatibility.

The following patches are going to provide the target-side trace which
might need these kind of macros.  It would be great if it can be shared
between host and target side both.

nvmet: fix discover log page when offsets are used

2019-04-11T15:28:30+00:00

The nvme target hadn't been taking the Get Log Page offset parameter
into consideration, and so has been returning corrupted log pages when
offsets are used. Since many tools, including nvme-cli, split the log
request to 4k, we've been breaking discovery log responses when more
than 3 subsystems exist.

Fix the returned data by internally generating the entire discovery
log page and copying only the requested bytes into the user buffer. The
command log page offset type has been modified to a native __le64 to
make it easier to extract the value from a command.
