Some of the options in sock_impl_opts could be different for different
sockets (even if they're using the same impl). However, outside of a
few selected options (recv_buf_size, send_buf_size), there was no
interface to change them.
This change will allow users to change impl_opts on a per-socket basis
when creating a socket. Sockets created through accept() inherit
impl_opts from the listening socket.

nvme_ctrlr_init_ana_log_page() had used cdata->mnan as active ns count
to allocate a buffer and read a ANA log page into the buffer.
However, cdata->mnan was larger than the real active ns count and caused
an issue when the corresponding NVMe-oF target set the bit 18 of the SGL
support field in the Identify Controller Data structure.
We still need to use cdata->mnan to allocate the buffer because
number of namespaces may be increased dynamically after initialization.
Hence, rename nvme_ctrlr::ana_log_page_size to
nvme_ctrlr::max_ana_log_page_size and calculate and use the active ns
count to read the ANA log page. Check if the current ana_log_page_size
is not larger than nvme_ctrlr->max_ana_log_page_size.

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names

Added new `ssl` based socket implementation.
For now we are using hard-coded PSK and only support TLS 1.3
One can use it via sock_set_default_impl RPCs
Nvme/TCP published secure channel specification (TP 8011)
Which is based on TLS 1.3 and PSK.
So this is a primary but not the oly use case.
Before any SSL connection can be established
we need to create SSL context.
The context should be client/server aware.
Similar to regular sockets, to establish connection
server must call SSL_accept and client must call SSL_connect.
For now I'm using PSK and not certificates since
we aim this for NVMe/TCP TP-8011 which supports only PSK.
Adding certificates later on will be very easy.
The complication with SSL state machine during accep and connect
comes with returned SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE.
According to documentation, call have to be repeated in this case.
Using openssl here for TLS from user space.
openssl also has support for kTLS.
Will be part of the next changes.
openssl doesn't have implemetation for iovec
only basic SSL_read and SSL_write.
So adding here SSL_readv and SSL_writev wrappers.
Tested using:
./build/examples/hello_sock -N ssl -H 127.0.0.1 -P 12345
./build/examples/hello_sock -N ssl -H 127.0.0.1 -P 12345 -S

Calculation of the ANA log page size should use the
identify ctrl MNAN field
(maximum number of allowed namespaces)
not the NN (maximum valid nsid value).
An ANA-enabled controller must have a non-zero MNAN value,
see NVMe Base Specification, Figure 251,
therefore nvme_ctrlr_init_ana_log_page() may safely use MNAN.
Since NN might be much higher than MNAN,
ANA log size based on NN may results in a very large
log page and cause a failure to get ANA log,
e.g. if it is larger than the controller's MDTS.
Fix: replace cdata->nn with cdata->mnan

Almost all of these files share the exact same license text,

because the third clause contains company names - most say

IDXD has always been used everywhere but technically it stands for
the driver, not the HW (Intel Data Streaming Accelerator Driver)
where the X comes from "Streaming Accelerator" somehow. Anyway, the
underlying hardware is just DSA. It doesn't matter much now but
upcoming patches will add support for a new HW accelerator called
the Intel In-Memory Analytics Accelerator which we'll call IAA and
it will use the same (mostly) device driver (IDXD) as DSA. So, calling
the HW what it is will lessen confusion when adding IAA support.
This patch just does renaming for the accel_fw module and associated
files (RPC, etc).

Maximum Data Transfer Size indicates the maximum data transfer size
for a command that transfers data between memory and the controller.
SPDK NVMe driver will split IO request based on MDTS and stripe
boundary, however, if user submited a big enough IO size, SPDK
NVMe driver will run out of requests data structure and return
-EINVAL as the error code, it's OK for application who call SPDK
NVMe driver directly.
SPDK bdev module also will do similar split based on `max_segment_size`
and `max_num_segments`, but we don't set them for bdev/nvme driver,
once there was a big enough IO request, the NVMe driver will return
-EINVAL to bdev module, here we set `max_segment_size` based on MDTS
and set `max_num_segments` based on number of requests of NVMe
controller.
Fix#2403.

As described in the NVMe specification, a controller level reset
includes the following actions:
- the controller stops processing any outstanding admin or I/O
commands;
- all I/O SQs and CQs are deleted.
In a full controller reset sequence for a PCIe controller, if we do
a controller level reset first, we can abort outstanding commands
after the hardware has actually been stopped.
For NVMe-oF controller, each I/O qpair is an independent network
connection and is disconnected safely. We do not want to change
NVMe-oF controller.
Fixes the issue #2360

It's now possible to specify a time to wait until a connection to the
discovery controller and the NVM controllers it exposes is made.
Whenever that time is exceeded, a callback is immediately executed.
However, depending on the stage of the discovery process, we might need
to wait a while before actually stopping it (e.g. because a controller
attach is in progress). That means that a discovery service might be
visible for a while after it timed out.
