scsi: target: cxgbit: add support for IEEE_8021QAZ_APP_SEL_STREAM selector

2019-07-22T21:04:20+00:00

IEEE_8021QAZ_APP_SEL_STREAM is a valid selector for iSCSI connections, so
add code to use IEEE_8021QAZ_APP_SEL_STREAM selector to get priority mask.

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs,
  mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the
  removal of the osst driver (I heard from Willem privately that he
  would like the driver removed because all his test hardware has
  failed). Plus number of minor changes, spelling fixes and other
  trivia.

  The big merge conflict this time around is the SPDX licence tags.
  Following discussion on linux-next, we believe our version to be more
  accurate than the one in the tree, so the resolution is to take our
  version for all the SPDX conflicts"

Note on the SPDX license tag conversion conflicts: the SCSI tree had
done its own SPDX conversion, which in some cases conflicted with the
treewide ones done by Thomas & co.

In almost all cases, the conflicts were purely syntactic: the SCSI tree
used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the
treewide conversion had used the new-style ones ("GPL-2.0-only" and
"GPL-2.0-or-later").

In these cases I picked the new-style one.

In a few cases, the SPDX conversion was actually different, though.  As
explained by James above, and in more detail in a pre-pull-request
thread:

 "The other problem is actually substantive: In the libsas code Luben
  Tuikov originally specified gpl 2.0 only by dint of stating:

  * This file is licensed under GPLv2.

  In all the libsas files, but then muddied the water by quoting GPLv2
  verbatim (which includes the or later than language). So for these
  files Christoph did the conversion to v2 only SPDX tags and Thomas
  converted to v2 or later tags"

So in those cases, where the spdx tag substantially mattered, I took the
SCSI tree conversion of it, but then also took the opportunity to turn
the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag.

Similarly, when there were whitespace differences or other differences
to the comments around the copyright notices, I took the version from
the SCSI tree as being the more specific conversion.

Finally, in the spdx conversions that had no conflicts (because the
treewide ones hadn't been done for those files), I just took the SCSI
tree version as-is, even if it was old-style.  The old-style conversions
are perfectly valid, even if the "-only" and "-or-later" versions are
perhaps more descriptive.

scsi: target/iblock: Fix overrun in WRITE SAME emulation

2019-07-02T20:35:52+00:00

WRITE SAME corrupts data on the block device behind iblock if the command
is emulated. The emulation code issues (M - 1) * N times more bios than
requested, where M is the number of 512 blocks per real block size and N is
the NUMBER OF LOGICAL BLOCKS specified in WRITE SAME command. So, for a
device with 4k blocks, 7 * N more LBAs gets written after the requested
range.

The issue happens because the number of 512 byte sectors to be written is
decreased one by one while the real bios are typically from 1 to 8 512 byte
sectors per bio.

This is less verbose and saves 7 bytes (i.e. the space for '/(null)') if
