In __qedf_probe(), if qedf->cdev is NULL which means
qed_ops->common->probe() failed, then the program will goto label err1, and
scsi_host_put() will free lport->host pointer. Because the memory qedf
points to is allocated by libfc_host_alloc(), it will be freed by
scsi_host_put(). However, the if statement below label err0 only checks
whether qedf is NULL but doesn't check whether the memory has been freed.
So a UAF bug can occur.
There are two ways to reach the statements below err0. The first one is
described as before, "qedf" should be set to NULL. The second one is goto
"err0" directly. In the latter scenario qedf hasn't been changed and it has
the initial value NULL. As a result the if statement is not reachable in
any situation.

The per-CPU statistics (struct fc_stats) is updated by getting a stable
per-CPU pointer via get_cpu() + per_cpu_ptr() and then performing the
increment. This can be optimized by using this_cpu_*() which will do
whatever is needed on the architecture to perform the update safe and
efficient. The read out of the individual value (fc_get_host_stats())
should be done by using READ_ONCE() instead of a plain-C access. The
difference is that READ_ONCE() will always perform a single access while
the plain-C access can be split by the compiler into two loads if it
appears beneficial. The usage of u64 has the side-effect that it is also
64bit wide on 32bit architectures and the read is always split into two
loads. The can lead to strange values if the read happens during an update
which alters both 32bit parts of the 64bit value. This can be circumvented
by either using a 32bit variables on 32bit architecures or extending the
statistics with a sequence counter.
Use this_cpu_*() API to update the statistics and READ_ONCE() to read it.

This driver has some left over "return 1" on failure style code mixed with
"return negative error codes" style code. The caller doesn't care so we
should just convert everything to return negative error codes.
Then there was a problem that there were two variables used to store error
codes which just resulted in confusion. If qedf_alloc_bdq() returned a
negative error code, we accidentally returned success instead of
propagating the error code. So get rid of the "rc" variable and use
"status" every where.
Also remove the "status = 0" initialization so that these sorts of bugs
will be detected by the compiler in the future.

actually used, with only fc_fill_fc_hdr() left inside of the header.

Firmware expects E_D_TOV field in connection offload parameters as “msec”.
Earlier incorrect value (100ms), was leading to abort from driver in the
case when data frames for read take more than 100ms from target side,
resulting in firmware reporting E_D_TOV expiration.
