The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:

ARC_BUILTIN_DTB_NAME

Currently cfg80211 checks for invalid channels whenever there is a
regulatory update and stops the active interfaces if it is operating on
an unsupported channel in the new regulatory domain.
This is done based on a regulatory flag REGULATORY_IGNORE_STALE_KICKOFF
set during wiphy registration which disables this enforcement when
unsupported interface modes are supported by driver.
Add support to enable this enforcement when Mesh Point interface type
is advertised by drivers.

Thought the underline driver MLME can handle association temporal
rejection with comeback, it is still useful to notify this to
user space, as user space might want to handle the temporal
rejection differently. For example, in case the comeback time
is too long, user space can deauthenticate immediately and try
to associate with a different AP.

The management registrations locking was broken, the list was
locked for each wdev, but cfg80211_mgmt_registrations_update()
iterated it without holding all the correct spinlocks, causing
list corruption.
Rather than trying to fix it with fine-grained locking, just
move the lock to the wiphy/rdev (still need the list on each
wdev), we already need to hold the wdev lock to change it, so
there's no contention on the lock in any case. This trivially
fixes the bug since we hold one wdev's lock already, and now
will hold the lock that protects all lists.

[fix whitespace]

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
So, use the struct_size() helper to do the arithmetic instead of the
argument "size + count * size" in the kzalloc() functions.
Also, take the opportunity to refactor the memcpy() call to use the
flex_array_size() helper.

Currently during CAC start or other radar events, the DFS
domain is fetched from cfg based on global DFS domain,
even if the wiphy regdomain disagrees.
But this could be different in case of self managed wiphy's
in case the self managed driver updates its database or supports
regions which has DFS domain set to UNSET in cfg80211 local
regdomain.
So for explicitly self-managed wiphys, just use their DFS
domain.

The wrong enum was used here, leading to warnings.
Just use a u32 instead.

Signed-off-by: Johannes Berg <johannes.berg@intel.com>
This patch adds support for BSS color collisions to the wireless subsystem.
Add the required functionality to nl80211 that will notify about color
collisions, triggering the color change and notifying when it is completed.

[remove unnecessary NULL initialisation]
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
The it_present member of struct ieee80211_radiotap_header is treated as a
flexible array (multiple u32s can be conditionally present). In order for
memcpy() to reason (or really, not reason) about the size of operations
against this struct, use of bytes beyond it_present need to be treated
as part of the flexible array. Add a trailing flexible array and
initialize its initial index via pointer arithmetic.

When we exceed the limit of BSS entries, this function will free the
new entry, however, at this time, it is the last door to access the
inputed ies, so these ies will be unreferenced objects and cause memory
leak.
Therefore we should free its ies before deallocating the new entry, beside
of dropping it from hidden_list.

In non-split data, we shouldn't be adding S1G and 6 GHz
data (or future bands) since we're really close to the
4k message size limit. Remove those bands, any modern
userspace that can use S1G or 6 GHz should already be
using split dumps, and if not then it needs to update.

To discover a hidden AP on the 6GHz band, the probe request
sent to the AP needs to include the AP's SSID, as some APs
would not respond with a probe response based only on short
SSID match.
To support hidden AP discovery over the 6GHz band,
when constructing the specific 6GHz band scan also include
SSIDs that were part of the original scan request, so these
can be used in the probe requests transmitted during scan.

There may be cases where vendor-specific elements need to be
used over the air. Rather than have driver or firmware add
them and possibly cause problems that way, add them to the
iftype-data band capabilities. This way we can advertise to
userspace first, and use them in mac80211 next.

We used to set regulatory info before the registration of
the device and then the regulatory info didn't get set, because
the device isn't registered so there isn't a device to set the
regulatory info for. So set the regulatory info after the device
registration.
Call reg_process_self_managed_hints() once again after the device
registration because it does nothing before it.

There's a WARN_ON here but it says nothing, and the later
