We currently have two levels of strict validation:
1) liberal (default)
- undefined (type >= max) & NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
- garbage at end of message accepted
2) strict (opt-in)
- NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
Split out parsing strictness into four different options:
* TRAILING - check that there's no trailing data after parsing
attributes (in message or nested)
* MAXTYPE - reject attrs > max known type
* UNSPEC - reject attributes with NLA_UNSPEC policy entries
* STRICT_ATTRS - strictly validate attribute size
The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().
Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.
We end up with the following renames:
* nla_parse -> nla_parse_deprecated
* nla_parse_strict -> nla_parse_deprecated_strict
* nlmsg_parse -> nlmsg_parse_deprecated
* nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
* nla_parse_nested -> nla_parse_nested_deprecated
* nla_validate_nested -> nla_validate_nested_deprecated

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.
Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.
Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.
In effect then, this adds fully strict validation for any new command.

Bitmaps are defined on unsigned longs, so the usage of u32[2] in the
wlcore driver is incorrect. As noted by Peter Zijlstra, casting arrays
to a bitmap is incorrect for big-endian architectures.
When looking at it I observed that:
- operations on reg_ch_conf_pending is always under the wl_lock mutex,
so set_bit is overkill
- the only case where reg_ch_conf_pending is accessed a u32 at a time is
unnecessary too.
This patch cleans up everything in this area, and changes tmp_ch_bitmap
to have the proper alignment.

During "wlan-up", we are programming the FW into the WiFi-chip. However,
re-programming the FW doesn't work, unless a power cycle of the WiFi-chip
is made in-between the programmings.
To conform to this requirement and to fix the regression in a simple way,
let's start by allowing that the SDIO card (WiFi-chip) may stay powered on
(runtime resumed) when wl12xx_sdio_power_off() returns. The intent with the
current code is to treat this scenario as an error, but unfortunate this
doesn't work as expected, so let's fix this.
The other part is to guarantee that a power cycle of the SDIO card has been
completed when wl12xx_sdio_power_on() returns, as to allow the FW
programming to succeed. However, relying solely on runtime PM to deal with
this isn't sufficient. For example, userspace may prevent runtime suspend
via sysfs for the device that represents the SDIO card, leading to that the
mmc core also keeps it powered on. For this reason, let's instead do a
brute force power cycle in wl12xx_sdio_power_on().

Now with wlcore using PM runtime, we can also add support for Linux
generic wakeirq handling for it if configured in the dts file.
The wakeirq can be configured as the second interrupt in the dts file
with interrupts-extended property where it is the padconf irq of the OOB
GPIO pin used for wlcore interrupt.
Note that eventually we should also allow configuring wlcore to use the
SDIO dat1 IRQ for wake-up, and in that case the the wakeirq should be
configured to be the padconf interrupt of the dat1 pin and not the
padconf interrupt of the OOB GPIO pin.

And we want to set WL1271_FLAG_INTENDED_FW_RECOVERY and actually clear
it too in wl1271_recovery_work() and just downgrade the error to a
warning to prevent overly verbose output.

Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

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.

With runtime PM tested working for wlcore with no autosuspend, we can

We have wl12xx_boot() call wl12xx_enable_interrupts() and if we have

wlcore: ERROR ELP wakeup timeout!

only after that call pm_runtime_get_sync() when interrupts are enabled.
And only after that do the check for wl12xx_need_fw_change().

After enabling runtime PM, if we force hardware reset multiple times with:

We will after few tries get the following error:
wlcore: ERROR timeout waiting for the hardware to complete initialization
And then wlcore is unable to reconnect until after the wlcore related modules
are reloaded.
Let's fix this by moving pm_runtime_put() earlier before we restart the hardware.
And let's use the sync version to make sure we're done before we restart.
Note that we still will get -EBUSY warning from wl12xx_sdio_set_power() but let's
fix that separately once we know exactly why we get the warning.

We can update wlcore to use PM runtime by adding functions for
wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing
calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls
to pm_runtime_get_sync() and pm_runtime_put().
Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume()
functions are based on simplified versions of wl1271_ps_elp_sleep() and
wl1271_ps_elp_wakeup().
We don't want to use the old functions as we can now take advantage of
the runtime PM usage count. And we don't need the old elp_work at all.
And we can also remove WL1271_FLAG_ELP_REQUESTED that is no longer needed.
Pretty much the only place where we are not just converting the existing
functions is wl1271_op_suspend() where we add pm_runtime_put_noidle()
to keep the calls paired.
As the next step is to implement runtime PM autosuspend, let's not add
wrapper functions for the generic runtime PM calls. We would be getting
rid of any wrapper functions anyways.
After autoidle we should be able to start using Linux generic wakeirqs
for the padconf interrupt.

We can have pm_runtime_get_sync() return 1, and we can have
pm_runtime_put_sync() return -EBUSY. See rpm_suspend() and
rpm_resume() for more information.
Fix the issue by returning 0 from wl12xx_sdio_power_on() on success.
And use pm_runtime_put() instead of pm_runtime_put_sync() for
wl12xx_sdio_power_off(), then the MMC subsystem will idle the bus
when suitable.
Otherwise wlcore can sometimes get confused and may report bogus
errors and WLAN connection can fail.
Note that while wlcore checks the return value for wl1271_power_on(),
the return value is ignored for wl1271_power_off(). Let's fix them
both though to avoid further confusion in the future.

pm_runtime handles sdio power on and power off transitions.
An old workaround for trying to control the power explicitly from the
driver was in fact causing failures on suspend/resume as the mmc layer
already power the module on resume.
In case of resume pm_runtime_get sync returns a positive device's usage
count causing the driver to try an re-initialize an already initialized
device. This was causing sdio bus failure on resume.
Remove this manual power on/off sequence as it is in-fact not needed.

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

In case there is no valid MAC address kernel generates random one. This
patch propagate this generated MAC address back to NVS data which will be
uploaded to wl1251 chip. So HW would have same MAC address as linux kernel
uses.

correct mac address since beginning of chip usage.

This patch implements parsing MAC address from NVS data which are sent to
wl1251 chip. Calibration NVS data could contain valid MAC address and it
will be used instead of randomly generated one.
This patch also moves code for requesting NVS data from userspace to driver
initialization code to make sure that NVS data will be there at time when
permanent MAC address is needed.
Calibration NVS data for wl1251 are device specific. Every device with
wl1251 chip should have been calibrated in factory and needs to provide own
calibration data.
Default example file wl1251-nvs.bin, found in linux-firmware repository,
contains MAC address 00:00:20:07:03:09. So this MAC address is marked as
invalid as it is not real device specific address, just example one.
