Commit ffbd0c8c1e7f ("wifi: mac80211: add an element parsing unit test")
and commit 730eeb17bbdd ("wifi: cfg80211: add first kunit tests, for
element defrag") add new configs that depend on !KERNEL_6_2, but the config
option KERNEL_6_2 does not exist in the tree. This dependency is used for
handling backporting to restrict the option to certain kernels but this
really should not be carried around the mainline kernel tree.
Clean up this needless dependency on the non-existing option KERNEL_6_2.

When LIB80211_CRYPT_CCMP is enabled and CRYPTO is disabled, it results in unmet
direct dependencies config warning. The reason is that LIB80211_CRYPT_CCMP
selects CRYPTO_AES and CRYPTO_CCM, which are subordinate to CRYPTO. This is
reproducible with CRYPTO disabled and R8188EU enabled, where R8188EU selects
LIB80211_CRYPT_CCMP but does not select or depend on CRYPTO.
Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Back with commit c8c240e284b3 (cfg80211: reg: remove support for
built-in regdb, 2015-10-15), support for using CFG80211_INTERNAL_REGDB
was removed in favor of loading the regulatory database as firmware
file. The documentation of CFG80211_CRDA_SUPPORT was not adjusted,
though, which is why it still mentions mentions the old way of loading
via the internal regulatory database.
Remove it so that the kernel option only mentions using the firmware
file.

Instead of open coding the CCM aead mode in the driver, and invoking
the AES block cipher block by block, use a ccm(aes) aead transform
which already encapsulates this functionality. This is a cleaner use
of the crypto API, and permits optimized implementations to be used,
which are typically much faster and deal more efficiently with the
SIMD register file, which usually needs to be preserved/restored in
order to use special AES instructions.

The conversion is actually:
- add blank lines and indentation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

New options introduced by the patch this fixes are still
enabled even if CFG80211 is disabled.

CONFIG_CFG80211_REQUIRE_SIGNED_REGDB=y
CONFIG_CFG80211_USE_KERNEL_REGDB_KEYS=y
# CONFIG_LIB80211 is not set
When CFG80211_REQUIRE_SIGNED_REGDB is enabled, it selects
SYSTEM_DATA_VERIFICATION which selects SYSTEM_TRUSTED_KEYRING
that need extract-cert tool. extract-cert needs some openssl
headers to be installed on the build machine.
Instead of adding missing "depends on CFG80211", it's
easier to use a 'if' block around all options related
to CFG80211, so do that.

Currently CRDA implements the signature checking, and the previous
commits added the ability to load the whole regulatory database
into the kernel.
However, we really can't lose the signature checking, so implement
it in the kernel by loading a detached signature (regulatory.db.p7s)
and check it against built-in keys.

Parsing and building C structures from a regdb is no longer needed

kernel image to achieve the same effect.

As the current regulatory database is only about 4k big, and already
difficult to extend, we decided that overall it would be better to
get rid of the complications with CRDA and load the database into the
kernel directly, but in a new format that is extensible.
The new file format can be extended since it carries a length field
on all the structs that need to be extensible.
In order to be able to request firmware when the module initializes,
move cfg80211 from subsys_initcall() to the later fs_initcall(); the
firmware loader is at the same level but linked earlier, so it can
be called from there. Otherwise, when both the firmware loader and
cfg80211 are built-in, the request will crash the kernel. We also
need to be before device_initcall() so that cfg80211 is available
for devices when they initialize.

The change to only export WEXT symbols when required could break
the build if CONFIG_CFG80211_WEXT was explicitly disabled while
a driver like orinoco selected it.
Fix this by hiding the symbol when it's required so it can't be
disabled in that case.

When a fully converted cfg80211 driver needs cfg80211-wext for
userspace API purposes, the symbols need not be exported. When
other drivers (orinoco/hermes or ipw2200) are enabled, they do
need the symbols exported as they use them directly.
Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig
symbol (instead of just CFG80211_WEXT) and export the functions
only if requested - this saves about 1/2k due to the size of
EXPORT_SYMBOL() itself.

This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a.
It's causing severe userspace breakage. Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.
Please see [1] for example of the userspace breakage this is causing.
In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.
To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

This option has been marked for deprecation and removal for
a little more than two years, but it's not been very clearly
signalled since it was always possible to just select it.
Make it unselectable now to signal anyone who's still using
it after all this time more clearly. They can still get it
back, but only by patching the kernel.

Since "wireless-regdb: remove antenna gain" was merged in the
wireless-regdb tree, the awk script parser has been incompatible
with the 'official' regulatory database. This fixes that up.
Without this change the max EIRP is set to 0 making 802.11 devices
useless.
The fragile nature of the awk parser must be replaced, but ideas
over how to do that in the most scalable way are being reviewed.
In the meantime update the documentation for CFG80211_INTERNAL_REGDB
so folks are aware of expectations for now.

Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT
iff there is an active station interface that is associated to
an AP operating on the same channel in the 2 GHz band or the same UNII band
(in the 5 GHz band). This relaxation is not allowed if the channel is
marked with IEEE80211_CHAN_RADAR.
Note that this is a permissive approach to the FCC definitions,
that require a clear assessment that the device operating the AP is
an authorized master, i.e., with radar detection and DFS capabilities.
It is assumed that such restrictions are enforced by user space.
Furthermore, it is assumed, that if the conditions that allowed for
the operation of the GO on such a channel change, i.e., the station
interface disconnected from the AP, it is the responsibility of user
space to evacuate the GO from the channel.

This adds CONFIG_CFG80211_CERTIFICATION_ONUS which is to
be used for features / code which require a bit of work on
the system integrator's part to ensure that the system will
still pass 802.11 regulatory certification. This option is
also usable for researchers and experimenters looking to add
code in the kernel without impacting compliant code.
We'd use CONFIG_EXPERT alone but it seems that most standard
Linux distributions are enabling CONFIG_EXPERT already. This
allows us to define 802.11 specific kernel features under a
flag that is intended by design to be disabled by standard
Linux distributions, and only enabled by system integrators
or distributions that have done work to ensure regulatory
certification on the system with the enabled features.

Almost all wireless tools have transitioned to
or at least added compatibility with nl80211 so
there's no real need for CONFIG_CFG80211_WEXT
any more. Mark it for removal, and also change

This code has been on the list to remove for a long
time, so disable it by default, add a warning to its
Kconfig, and schedule it for removal in 3.5.
The only known dependency, hal, has not required it
since its 0.5.12 release, which was in early 2009
and hal has since been deprecated completely.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

This patch provides infrastructure for machine translation of the
regulatory rules database used by CRDA into a C data structure.
It includes code for searching that database as an alternative
to dynamic regulatory rules updates via CRDA. Most people should
use CRDA instead of this infrastructure, but it provides a better
alternative than the WIRELESS_OLD_REGULATORY infrastructure (which
can now be removed).

Refactor wext to
* split out iwpriv handling
* split out iwspy handling
* split out procfs support
* allow cfg80211 to have wireless extensions compat code
w/o CONFIG_WIRELESS_EXT
After this, drivers need to
- select WIRELESS_EXT - for wext support
- select WEXT_PRIV - for iwpriv support
- select WEXT_SPY - for iwspy support
except cfg80211 -- which gets new hooks in wext-core.c
and can then get wext handlers without CONFIG_WIRELESS_EXT.
Wireless extensions procfs support is auto-selected
based on PROC_FS and anything that requires the wext core
(i.e. WIRELESS_EXT or CFG80211_WEXT).

Bob reported that he got warnings in IBSS mode about
the ssid_len being zero on a joined event, but only
when kmemcheck was enabled. This appears to be due
to a race condition between drivers and userspace,
when the driver reports joined but the user in the
meantime decided to leave the IBSS again, the warning
would trigger. This was made more likely by kmemcheck
delaying the code that does the check and sends the
event.
So first, make the warning trigger closer to the
driver, which means it's not locked, but since only
the warning depends on it that's ok.
And secondly, users will not want to have spurious
warnings at all, so make those that are known to be
racy in such a way configurable.

This introduces a new NL80211_CMD_TESTMODE for testing
and calibration use with nl80211. There's no multiplexing
like like iwpriv had, and the command is not available by
default, it needs to be explicitly enabled in Kconfig and
shouldn't be enabled in most kernels.
The command requires a wiphy index or interface index to
identify the device to operate on, and the new TESTDATA
attribute. There also is API for sending replies to the
command, and testmode multicast messages (on a testmode
multicast group).
I've also updated mac80211 to be able to pass through the
command to the driver, since it itself doesn't implement
the testmode command.
Additionally, to give people an idea of how to use the
command, I've added a little code to hwsim that makes use
of the new command to set the powersave mode, this is
currently done via debugfs and should remain there, and
the testmode command only serves as an example of how to
use this best -- with nested netlink attributes in the
TESTDATA attribute. A hwsim testmode tool can be found at
http://git.sipsolutions.net/hwsim.git/. This tool is BSD
licensed so people can easily use it as a basis for their
own internal fabrication and validation tools.

The way I initially thought we could do wireless extensions
is by making all the compat code in cfg80211 be independent
of CONFIG_WIRELESS_EXT, but this is turning out to not be
feasible. Therefore, fix the Kconfig help text and make the
option default to yes, so people won't get a nasty surprise
when mac80211 will get rid of its 'select WIRELESS_EXT' any
time now.

To be easier on drivers and users, have cfg80211 register an
rfkill structure that drivers can access. When soft-killed,
simply take down all interfaces; when hard-killed the driver
needs to notify us and we will take down the interfaces
after the fact. While rfkilled, interfaces cannot be set UP.

The scan capability added to cfg80211/nl80211 introduced a
dependency on nl80211 by cfg80211. We can thus no longer have
just cfg80211 without nl80211. Specifically, cfg80211_scan_done()
calls nl80211_send_scan_aborted() or nl80211_send_scan_done().
Now we remove the option for user to select nl80211. It will always
be compiled if user selects cfg80211.
