When ath6kl was reworked to share code between regular and scheduled scans
in commit 3b8ffc6a22 ("ath6kl: Configure probed SSID list consistently"),
probed SSID entry changed from 1-index to 0-indexed. However,
ath6kl_cfg80211_scan_complete_event() was missed in that change. Fix its
indexing so that we correctly clear out the probed SSID list.

Commit dd45b7598f ("ath6kl: Include match ssid list in scheduled scan")
merged the probed and matched SSID lists before sending them to the
firmware. In the process, it assumed match set support is always available
in ath6kl_set_probed_ssids, which breaks scans for hidden SSIDs. Now, check
that the firmware supports matching SSIDs in scheduled scans before setting
MATCH_SSID_FLAG.

The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in wireless-drivers by changing it to BIT_ULL instead. In addition, there are
some places which don't use BIT nor BIT_ULL macros so align those as well.

"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.

Files removed in 'net-next' had their license header updated
in 'net'. We take the remove from 'net-next'.
Signed-off-by: David S. Miller <davem@davemloft.net>
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.

Network devices can allocate reasources and private memory using
netdev_ops->ndo_init(). However, the release of these resources
can occur in one of two different places.
Either netdev_ops->ndo_uninit() or netdev->destructor().
The decision of which operation frees the resources depends upon
whether it is necessary for all netdev refs to be released before it
is safe to perform the freeing.
netdev_ops->ndo_uninit() presumably can occur right after the
NETDEV_UNREGISTER notifier completes and the unicast and multicast
address lists are flushed.
netdev->destructor(), on the other hand, does not run until the
netdev references all go away.
Further complicating the situation is that netdev->destructor()
almost universally does also a free_netdev().
This creates a problem for the logic in register_netdevice().
Because all callers of register_netdevice() manage the freeing
of the netdev, and invoke free_netdev(dev) if register_netdevice()
fails.
If netdev_ops->ndo_init() succeeds, but something else fails inside
of register_netdevice(), it does call ndo_ops->ndo_uninit(). But
it is not able to invoke netdev->destructor().
This is because netdev->destructor() will do a free_netdev() and
then the caller of register_netdevice() will do the same.
However, this means that the resources that would normally be released
by netdev->destructor() will not be.
Over the years drivers have added local hacks to deal with this, by
invoking their destructor parts by hand when register_netdevice()
fails.
Many drivers do not try to deal with this, and instead we have leaks.
Let's close this hole by formalizing the distinction between what
private things need to be freed up by netdev->destructor() and whether
the driver needs unregister_netdevice() to perform the free_netdev().
netdev->priv_destructor() performs all actions to free up the private
resources that used to be freed by netdev->destructor(), except for
free_netdev().
netdev->needs_free_netdev is a boolean that indicates whether
free_netdev() should be done at the end of unregister_netdevice().
Now, register_netdevice() can sanely release all resources after
ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit()
and netdev->priv_destructor().
And at the end of unregister_netdevice(), we invoke
netdev->priv_destructor() and optionally call free_netdev().

This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.
Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

Channels 34/38/42/46 can only be used for compatibility with old devices sold
in Japan. Modern products, such as AR6003/AR6004 don't support these channels.
Keeping them in the upstream is error prone and requires full network stack
support. A custom patch should be used in case such compatibility is required.
Without this one, a user is able to start an AP using wpa_supplicant,
for example, on one of these channels (34/38/42/46), without getting
any warning/error from the cfg80211 or ath6kl - which is correct
(since these channels match regdom rules). However, the AR6003 and its
firmware (we're using v3.4.0.225) will fail and return

The hostap_80211_rx() function is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:
drivers/net/wireless/intersil/hostap/hostap_80211_rx.c: In function ‘hostap_80211_rx’:
arch/x86/include/asm/string_32.h:77:14: warning: ‘src’ may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/wireless/intel/ipw2x00/libipw_rx.c: In function ‘libipw_rx’:
arch/x86/include/asm/string_32.h:77:14: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
arch/x86/include/asm/string_32.h:78:22: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.
The same code is duplicated several times in the kernel, so this
patch uses the same workaround for all copies. The exact configuration
was hit only very rarely in randconfig builds and I only saw it
in three drivers, but I assume that all of them are potentially
affected, and it's better to keep the code consistent.

The ath6kl driver attempts to get the txpower value from the radio by first
clearing the existing stored value and then watching the value to become
non-zero.
APs allow setting client power to values from -127..127, but this radio
is not capable of setting values less then 0 and so will report txpower
as 0dbm for both negative and 0 client power values.
When the radio has txpower set to 0dbm txpower (equivalent to 1mw) the
ath6kl_cfg80211_get_txpower() function will remain in the
wait_event_interruptible_timeout() loop waiting for the value to be
non-zero, and will eventually timeout. This results in a 5 second delay in
response. However, the correct value of zero is eventually returned.
The 6004 defaults to 63dbm which is then limited by regulatory and
hardware limits with max of 18dbm (6003 max is 16dbm), therefore we can
use values larger then these to be able to determine when the value has
been updated.
To correct the issue, set the value to a nonsensical value (255) and wait
for it to change to the valid value.
Tested on both 6003 and 6004 based radios. Return value of zero is
correctly returned in an expected amount of time (similar to when
returning non-zero values) when AP client power is set to both 0 and
negative values.

The use of config_enabled() against config options is ambiguous. In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED(). Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention
clearer.
This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.
I noticed two cases where config_enabled() is used against a tristate
option:
- config_enabled(CONFIG_HWMON)
[ drivers/net/wireless/ath/ath10k/thermal.c ]
- config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
[ drivers/gpu/drm/gma500/opregion.c ]
I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

The upper layers (eg. connman) are not notified of the tethering mode
status change. So, tethering can not be activated anymore.
This patch adds a netif_carrier_off() call when stopping AP mode to fix
the problem.

One minute after a successful connection, the kernel checks if the
frequency and the channel width are well configured for the country we
are in. (regulatory domain)
ath6kl driver was setting the NL80211_CHAN_HT20 channel without checking
for the HT capabilities. (we should have NL80211_CHAN_NO_HT in our
case because the firmware did not support HT)
This patch adds a check on ht_cap.ht_supported in order to create the
channel corresponding to the firmware capabilities.

When enabling WLAN tethering, a new AP is visible and a STA could
connect to it. When the STA tries to authenticate to the newly created
AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way
Handshake.
In ath6kl_rx(), the ath6kl_find_sta() function is looking for the
h_source field of the Ethernet frame header received by the STA. The
datap pointer that points to the Ethernet frame header is incorrect,
and was pointing at the wrong offset in the buffer.
This commit adds a pad_before_data_start offset to set the datap pointer
to the Ethernet frame header. datap->h_source parameter is now really
pointing to the source ethernet address and the authentication process
can continue.

Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.
In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.
Supporting beacon report is required for Multi Band Operation (MBO).

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of

Certain 6004 firmware releases redefine the WMI_TXE_NOTIFY_EVENTID event
number and sends the new event frequently. However it doesn't have the
tx-err-notify feature and thus this firmware capability flag isn't set on
the firmware package. By guarding the processing of this event by the same
method we guard the sending of the WMI_SET_TXE_NOTIFY_CMDID command, we
can ignore the spurious event that we don't know how to process.
Without this change we call cfg80211_cqm_txe_notify() with possibly bad
data.

Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.
When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.

When we disconnect from the AP, drivers call cfg80211_disconnect().
This doesn't know whether the disconnection was initiated locally
or by the AP though, which can cause problems with the supplicant,
for example with WPS. This issue obviously doesn't show up with any
mac80211 based driver since mac80211 doesn't call this function.
Fix this by requiring drivers to indicate whether the disconnect is
locally generated or not. I've tried to update the drivers, but may
not have gotten the values correct, and some drivers may currently
not be able to report correct values. In case of doubt I left it at
false, which is the current behaviour.
For libertas, make adjustments as indicated by Dan Williams.

This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

802.11ad adds new a network type (PBSS) and changes the capability
field interpretation for the DMG (60G) band.
The same 2 bits that were interpreted as "ESS" and "IBSS" before are
re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
values are: "IBSS", "PBSS" (new) and "AP".
In order to get the BSS struct for the new PBSS networks, change the
cfg80211_get_bss() function to take a new enum ieee80211_bss_type
argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)
The remaining bits in "capa_mask" and "capa_val" are used only for
privacy matching so replace those two with a privacy enum as well.

For some reason, we made the bandwidth separate flags, which
is rather confusing - a single rate cannot have different
bandwidths at the same time.
Change this to no longer be flags but use a separate field
for the bandwidth ('bw') instead.
While at it, add support for 5 and 10 MHz rates - these are
reported as regular legacy rates with their real bitrate,
but tagged as 5/10 now to make it easier to distinguish them.
In the nl80211 API, the flags are preserved, but the code
now can also clearly only set a single one of the flags.

This is really just duplicating the list of information that's

Two small changes are needed:
* remove STATION_INFO_ASSOC_REQ_IES complete, but the length
(assoc_req_ies_len) can be used instead
* add NL80211_STA_INFO_RX_DROP_MISC which exists internally
