0961d9874a rtlwifi: Fix duplicate tests of one of the RX descriptors
In drivers rtl8188ee, rtl8821ae, rtl8723be, and rtl8192ee, the reason
for a wake-up is returned in the fourth RX descriptor in bits 29-31. Due
to typographical errors, all but rtl8821ae test bit 31 twice and fail to
test bit 29.

This error causes no problems as the tests are only used to set bits in
the output of an optional debugging statement.

030b43671a wireless: prefix header search paths with $(srctree)/
Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5b
("kbuild: do not drop -I without parameter").

I also removed one header search path in:

  drivers/net/wireless/broadcom/brcm80211/brcmutil/Makefile

I was able to compile without it.

28484b6b37 rtl8723ae: Re-introduce the adaptive rate control
This re-introduces the function rtl8723e_dm_refresh_rate_adaptive_mask.

This function was present in a previous version of the code base,
it works just fine for me -- as long as it is not using stale data.

Unlike the original version of this function it avoids using
dm.undec_sm_pwdb when no beacon was received.

Assume instead that the signal level is low.

Fix the state machine in rtl8723e_dm_cck_packet_detection_thresh

from CCK_PD_STAGE_LOWRSSI/CCK_FA_STAGE_LOW to CCK_PD_STAGE_HIGHRSSI

This appears to trigger a firmware bug and causes severe
problems with rtl8723ae PCI devices.

When the power save mode is activated for longer periods
of time the firmware stops to receive any packets.

This problem was exposed by commit 873ffe154a ("rtlwifi:
Fix logic error in enter/exit power-save mode").

Previously the power save mode was only active rarely and
only for a short time so that the problem was not noticeable.

The Realtek rtl8188ctv (0x0bda:0x018a) is a highly integrated single-chip
WLAN USB2.0 network interface controller.

Currently rtl8188ctv is supported by rtlwifi driver.
It is similar to the rtl8188cus(0x0bda:0x818a) and uses the same config.

length of the first argument, the compiler warns of the possibility of an
unterminated string. Using strlcpy() forces a null at the end.

622e938240 rtl818x: Replace mdelay() with msleep() in rtl8225se_rf_init
rtl8225se_rf_init() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().
This patch only replaces the mdelay() that has >20ms time to wait.

This is found by a static analysis tool named DCNS written by myself.

9a98302de1 rtlwifi: rtl8821ae: fix firmware is not ready to run
Without this patch, firmware will not run properly on rtl8821ae, and it
causes bad user experience. For example, bad connection performance with
low rate, higher power consumption, and so on.

rtl8821ae uses two kinds of firmwares for normal and WoWlan cases, and
each firmware has firmware data buffer and size individually. Original
code always overwrite size of normal firmware rtlpriv->rtlhal.fwsize, and
this mismatch causes firmware checksum error, then firmware can't start.

In this situation, driver gives message "Firmware is not ready to run!".

This patch ensures all delayed works done before entering PS to satisfy
our expectation, so use cancel_delayed_work_sync() instead. An exception
is delayed work ips_nic_off_wq because running task may be itself, so add
a parameter ips_wq to deinit function to handle this case.

6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

0a9f8f0a1b rtlwifi: fix btmpinfo timeout while processing C2H_BT_INFO
In former patch, I enqueu all C2H commands and processed by a workqueue.
In case C2H_BT_INFO will issue a H2C command to set BT reg, and wait for
a C2H ack. But it is totally impossible that C2H workqueue waits for a
C2H command, so kernel log warn
	rtlwifi: :<0> btmpinfo wait (req_num=0) timeout

Since the C2H ack command C2H_BT_MP can be safely processed in interrupt
context, add a fast command path to deal with the command.

9ae6ed271a rtlwifi: use sk_buff to queue C2H commands
We use 'struct rtl_c2hcmd' to store C2H commands originally, and the code
is slightly complex to enqueue and dequeue and also wastes time to
allocate and memcpy data. Since C2H commands are asynchronous events,
they can be processed in work queue, so RX ISR enqueues C2H result in
removal of rtl_c2h_packet_handler().

6acfbb81ab rtlwifi: support accurate nullfunc frame tx ack report
In order to realize the keep-alive mechanism in mac80211 stack, reporting
accurate tx ack status for nullfunc frame is added in this commit.

If current frame is nullfunc frame, we ask firmware to report by filling
TX report bit in TX descriptor. After this frame DMA done, TX interrupt is
triggered but TX status is unknown at this moment, so enqueue this skb
into tx_report->queue. Finally, C2H report will be received if the frame
is transmitted successfully or retried over, and then we report to mac80211
with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if
failure or timeout (one second), we report to mac80211 without this flag.

af8a41cccf rtlwifi: cleanup 8723be ant_sel definition
Some HP laptops have only a single wifi antenna. This would not be a
problem except that they were shipped with an incorrectly encoded
EFUSE. It should have been possible to open the computer and transfer
the antenna connection to the other terminal except that such action
might void the warranty, and moving the antenna broke the Windows
driver. The fix was to add a module option that would override the
EFUSE encoding. That was done with commit c18d8f5095 ("rtlwifi:
rtl8723be: Add antenna select module parameter"). There was still a
problem with Bluetooth coexistence, which was addressed with commit
baa1702290 ("rtlwifi: btcoexist: Implement antenna selection").
There were still problems, thus there were commit 0ff78adeef
("rtlwifi: rtl8723be: fix ant_sel code") and commit 6d62269283
("rtlwifi: btcoexist: Fix antenna selection code"). Despite all these
attempts at fixing the problem, the code is not yet right. A proper
fix is important as there are now instances of laptops having
RTL8723DE chips with the same problem.

The module parameter ant_sel is used to control antenna number and path.
At present enum ANT_{X2,X1} is used to define the antenna number, but
this choice is not intuitive, thus change to a new enum ANT_{MAIN,AUX}
to make it more readable. This change showed examples where incorrect
values were used. It was also possible to remove a workaround in
halbtcoutsrc.c.

The experimental results with single antenna connected to specific path
are now as follows:
  ant_sel  ANT_MAIN(#1)  ANT_AUX(#2)
     0        -8            -62
     1        -62           -10
     2        -6            -60

514c603249 headers: untangle kmemleak.h from mm.h
Currently <linux/slab.h> #includes <linux/kmemleak.h> for no obvious
reason.  It looks like it's only a convenience, so remove kmemleak.h
from slab.h and add <linux/kmemleak.h> to any users of kmemleak_* that
don't already #include it.  Also remove <linux/kmemleak.h> from source
files that do not use it.

This is tested on i386 allmodconfig and x86_64 allmodconfig.  It would
be good to run it through the 0day bot for other $ARCHes.  I have
neither the horsepower nor the storage space for the other $ARCHes.

Update: This patch has been extensively build-tested by both the 0day
bot & kisskb/ozlabs build farms.  Both of them reported 2 build failures
for which patches are included here (in v2).

[ slab.h is the second most used header file after module.h; kernel.h is
  right there with slab.h. There could be some minor error in the
  counting due to some #includes having comments after them and I didn't
  combine all of those. ]

a6cf02e648 net/wireless: fix spaces and grammar copy/paste in vendor Kconfig help text
Lots of the wireless driver vendor Kconfig symol help text says
"questions about  cards." (2 spaces between "about" and "cards")

Besides dropping one of those spaces, it also needs some other word

c713fb071e rtlwifi: rtl8821ae: Fix connection lost problem correctly
There has been a coding error in rtl8821ae since it was first introduced,
namely that an 8-bit register was read using a 16-bit read in
_rtl8821ae_dbi_read(). This error was fixed with commit 40b368af4b
("rtlwifi: Fix alignment issues"); however, this change led to
instability in the connection. To restore stability, this change
was reverted in commit b8b8b16352 ("rtlwifi: rtl8821ae: Fix connection
lost problem").

Unfortunately, the unaligned access causes machine checks in ARM
architecture, and we were finally forced to find the actual cause of the
problem on x86 platforms. Following a suggestion from Pkshih
<pkshih@realtek.com>, it was found that increasing the ASPM L1
latency from 0 to 7 fixed the instability. This parameter was varied to
see if a smaller value would work; however, it appears that 7 is the
safest value. A new symbol is defined for this quantity, thus it can be
easily changed if necessary.

a3fa3669d1 rtlwifi: Use mutex to replace spin_lock to protect IPS and LPS
Enter/leavel IPS and LPS are large critical section, and they can't use
sleep function because running in atomic-context, which own a spin_lock.
In commit ba9f93f82a ("rtlwifi: Fix enter/exit power_save"), it moves
LPS functions to thread-context, so this commit can simply change LPS's
spin lock to mutex.
Considering IPS functions, rtl_ips_nic_on() may be called by TX tasklet
(softirq-context) that check whether packet is auth frame. Fortunately,
current mac80211 will ask driver to leave IPS using op_config with
changed flag IEEE80211_CONF_CHANGE_IDLE, before issuing auth frame, so
IPS functions can run in thread-context and use mutex to protect critical
section, too.
Also, this commit removes some useless spin locks.

5f647f4dfe rtlwifi: rtl_pci: Simplify some code be eliminating extraneous variables
In several places, the code assigns a variable inside an "if" or "case"
block, but uses it only once. The code is simplified by eliminating
the extraneous variable. With this change, one level of indenting is
saved.

This patch does not cause any functional changes in the binary code.

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.

In routine rtl92ee_set_fw_rsvdpagepkt(), the driver allocates an skb, but
never calls rtl_cmd_send_packet(), which will free the buffer. All other
rtlwifi drivers perform this operation correctly.

This problem has been in the driver since it was included in the kernel.
Fortunately, each firmware load only leaks 4 buffers, which likely
explains why it has not previously been detected.

0f61953dd0 rtlwifi: btcoexist: 23b 1ant: fix duplicated code for different branches
A typo led to this issue, which was detected with the help of Coccinelle.

In addition to fixing the error, the code is refactored to eliminate an
if statement.

6d62269283 rtlwifi: btcoexist: Fix antenna selection code
In commit 87d8a9f352 ("rtlwifi: btcoex: call bind to setup btcoex"),
the code turns on a call to exhalbtc_bind_bt_coex_withadapter(). This
routine contains a bug that causes incorrect antenna selection for those
HP laptops with only one antenna and an incorrectly programmed EFUSE.
These boxes are the ones that need the ant_sel module parameter.

In commit bcd37f4a08 ("rtlwifi: btcoex: 23b 2ant: let bt transmit when
hw initialisation done"), there is an additional error when the module
parameter ant_sel is used to select the auxilary antenna. The error is
that the antenna selection is not checked when writing the antenna
selection register.

d9ee6015e5 rtlwifi: make a couple arrays larger
This is a static checker fix.  "cal_num" is 10.  We're declaring the
tx_dt[] and rx_td[] arrays as 3 element arrays.  The static checker
complains that we do:

	tx_dt[cal] = (vdf_y[1]>>20)-(vdf_y[0]>>20);

"cal" is the iterator and it is in the 0-9 range so it looks like
we could corrupt memory.

1d9b168d8e rtlwifi: Fix fallback firmware loading
Commit f70e4df2b3 ("rtlwifi: Add code to read new versions of
firmware") added code to load an old firmware file if the new one is
not available.  Unfortunately that code is never reached because
request_firmware_nowait() does not wait for the firmware to show up
and returns 0 even if the file is not there.

Use the existing fallback mechanism introduced by commit 62009b7f12
("rtlwifi: rtl8192cu: Add new firmware") instead.

11f35c9504 rtlwifi: Fill in_4way field by driver
Because it isn't always correct to use EAPOL to check 4-way,
we add a timer to handle exception.

d0116f6f7b rtlwifi: kfree entry until after entry->bssid has been accessed
The current code kfree's entry and then dereferences it by accessing
entry->bssid.  Avoid the dereference-after-free by moving the kfree
after the access to entry->bssid.

Detected by CoverityScan, CID#1448600 ("Read from pointer after free")
