add_sd_cnt in info structure passed to i40iw_create_hmc_obj_type
must be 0 and since it is modified during the call, it must be
reset in the loop. This avoids unnecessarily reprogramming the
SDs multiple times with the same values.

Pull rdma updates from Doug Ledford:
"This is a fairly plain pull request. Lots of driver updates across the
stack, a huge number of static analysis cleanups including a close to
50 patch series from Bart Van Assche, and a number of new features
inside the stack such as general CQ moderation support.
Nothing really stands out, but there might be a few conflicts as you
take things in. In particular, the cleanups touched some of the same
lines as the new timer_setup changes.
Everything in this pull request has been through 0day and at least two
days of linux-next (since Stephen doesn't necessarily flag new
errors/warnings until day2). A few more items (about 30 patches) from
Intel and Mellanox showed up on the list on Tuesday. I've excluded
those from this pull request, and I'm sure some of them qualify as
fixes suitable to send any time, but I still have to review them
fully. If they contain mostly fixes and little or no new development,
then I will probably send them through by the end of the week just to
get them out of the way.
There was a break in my acceptance of patches which coincides with the
computer problems I had, and then when I got things mostly back under
control I had a backlog of patches to process, which I did mostly last
Friday and Monday. So there is a larger number of patches processed in
that timeframe than I was striving for.
Summary:
- Add iWARP support to qedr driver
- Lots of misc fixes across subsystem
- Multiple update series to hns roce driver
- Multiple update series to hfi1 driver
- Updates to vnic driver
- Add kref to wait struct in cxgb4 driver
- Updates to i40iw driver
- Mellanox shared pull request
- timer_setup changes

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Netdev event notifier registration/de-registration is not
synchronized with a lock and there is a possibility of a
duplicate registration of notifier before the unregister
completes.
Register netdev event notifiers during module init and
de-register them at module exit.
This avoids the need to tie the registration to first netdev
client interface open and de-registration to last client
interface close and the synchronization to achieve it.
This also fixes a crash due to duplicate registration.

The current timeout logic for Control Queue-Pair (CQP) OPs
does not take into account whether CQP makes progress but
rather blindly waits for a large timeout value, 100000 jiffies
for the completion event. Improve this by setting the timeout
based on whether the CQP is making progress or not. If the CQP
is hung, the timeout will happen sooner, in 5000 jiffies. Each
time the CQP progress is detetcted, the timeout extends by 5000
jiffies.

Remove NULL check for cm_node->listener in i40iw_accept
as listener is always present at this point.
Remove the check for cm_node->accept_pend and related code
in i40iw_cm_event_connected as the cm_node in this context
is only pertinent to active node and cm_node->accept_pend
is always 0.
This fixes the following smatch warnings,
drivers/infiniband/hw/i40iw/i40iw_cm.c:3691 i40iw_accept()
error: we previously assumed 'cm_node->listener' could be null
drivers/infiniband/hw/i40iw/i40iw_cm.c:4061 i40iw_cm_event_connected()
error: we previously assumed 'cm_node->listener' could be null
