      [SCSI] add refcouting around ctask usage in main IO patch · 60ecebf5
      由 Mike Christie 提交于 
      It is possible that a ctask could be completing and getting
cleaned up at the same time, we are finishing up the last
data transfer. This could then result in the data transfer
code using stale or invalid values. This patch adds a refcount
to the ctask. When the count goes to zero then we know the
transmit thread and recv thread or softirq are not touching
it and we can safely release it.

The eh should not need to grab a reference because it only cleans
up a task if it has both the xmit mutex and recv lock (or recv
side suspended).

      [SCSI] libiscsi, iscsi_tcp, iscsi_iser: check that burst lengths are valid. · ffd0436e
      由 Mike Christie 提交于 
      iSCSI RFC states that the first burst length must be smaller than the
max burst length. We currently assume targets will be good, but that may
not be the case, so this patch adds a check.

This patch also moves the unsol data out offset to the lib so the LLDs
do not have to track it.

      [SCSI] SCSI: sanitize INQUIRY strings · e5b3cd42
      由 Alan Stern 提交于 
      Sanitize the Vendor, Product, and Revision strings contained in an
INQUIRY result by setting all non-graphic or non-ASCII characters to ' '.
Since the standard disallows such characters, this will affect
only non-compliant devices.

To help maintain backward compatibility, NUL characters are treated
specially.  They are taken as string terminators; they and all the
following characters are set to ' '.  If some valid characters get
erased as a result... well, we weren't seeing them before so we haven't
lost anything.

The primary purpose of this change is to allow blacklist entries to
match devices with illegal Vendor or Product strings.

In addition, the patch updates a couple of function prototypes, giving
inq_result its correct type (unsigned char *).
