Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
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.

Rohit Fule 2d5cc60949 mwifiex: double the size of chan_stats array in adapter
When a user requests scan, driver sends multiple scan requests
to firmware, which might be active or passive. Firmware will
send channel statistics for each channel in the request. This will
be stored in chan_stats array.

Few channels might report hidden SSIDs in passive scan results.
So, once the original scan request is finished, driver issues an
active scan request for all channels which reported hidden SSIDs.
This will cause duplicates in the chan_stats array. At worst,
every channel will have a hidden SSID, in which case the driver
can issue active scan requests for each channel. So the complete
scan statistics size will be twice of existing limit.

At present maximum number of channels returned in scan statistics
is 31(BG) + 14(A) = 45. Clearly there will be an overflow of the
chan_stats array in the above mentioned scenario. To fix this
double the size of chan_stats array.

Douglas Anderson f0f7c2275f mwifiex: minor cleanups w/ sta_list_spinlock in cfg80211.c
The sta_list_spinlock looks to be used to control locking of the
list. Specifically when someone has the lock they may be allowed
to modify or delete elements of the list.

That implies that we shouldn't access the fields of the elements
returned by mwifiex_get_sta_entry() after we've released the
spinlock. Let's make some small changes so this is true.

It's unlikely that this matters since it looks to be just error
handling, but it's nice to be clean.

There's absolutely no reason to check to see if a list is empty
before iterating through it.  It's just like writing code like
this:

if (count != 0) {
  for (i = 0; i < count; i++) {
     ...
  }
}

The loop will already be avoided if "count == 0" so there was no
reason to check.

Commit 4d7ab36f0c ("mwifiex: Do not change bss_type in

keep the same style, in this way. Unique tuple (bss_type, bss_num) will
be able to locate the right priv structure.

Ganapathi Bhat bd69cddcdf mwifiex: replace netif_carrier_on/off by netif_device_attach/dettach
Driver is doing netif_carrier_off during suspend, which will set
the IFF_LOWER_UP flag to 0. As a result certain applications
will think this as a real carrier down and behave accordingly.
This will cause issues like loss of IP address, for example. To
fix this use netif_device_dettach during suspend.

Fixes: 0026b32d72 ('mwifiex: fix Tx timeout issue during suspend test')

Per the code, it didn't check if mwifiex_sdio_read_fw_status
finish successfully. We should at least check the return of
mwifiex_sdio_read_fw_status, otherwise the following check of
firmware_stat and adapter->mfg_mode is pointless as the device

Brian Norris 2f47150ab3 mwifiex: pcie: disable device DMA before unmapping/freeing buffers
In testing the mwifiex reset code path, I've noticed KASAN complaining
about some "overwritten poison values" in our RX buffer descriptors.
Because KASAN didn't notice this at the time of a CPU write, this seems
to suggest that the device is writing to this memory.

This makes a little sense, because when resetting, we don't necessarily
expect the device to be responsive, so we don't have a chance to disable
everything cleanly.

We can at least take the precaution of disabling DMA for the device
though, and in my testing that seems to clear up this particular issue.

This patch reorders the removal path so that we disable the device
*before* releasing our last PCIe buffers, and it clears/sets the bus
master feature from the PCI device when resetting.

Along the way, remove the insufficient (and confusing) error path in
mwifiex_pcie_up_dev() (it doesn't unwind things well enough, and it
doesn't propagate its errors upward anyway).

The card_reset() implementation should be setting our state flags and
cancelling commands for us (i.e., in mwifiex_shutdown_drv()), so let's
not do it here.

Also, this debugfs file is useful for testing and debugging the reset
feature, so we shouldn't do extra preparatory steps here, as that might
cause different reset behavior, which could either cause new bugs or
paper over existing ones that this debug feature should otherwise help
us catch.

Despite the name (and meticulous comments), this function frees no
memory and does not touch any locks. All it does is "delete" the list
heads -- which just means they'll be dangling, and we'll need to re-init
them if we use them again.

It seems like this code would work OK as a sort of canary for using the
list after we've torn everything down, so it's fine to keep the code;
let's just get the name and comments to match what's actually happening.
