commit 5fb9a9fb71a33be61d7d8e8ba4597bfb18d604d0 upstream.
AP_VLAN interfaces are virtual, so doesn't really exist as a type for
capabilities. When passed in as a type, AP is the one that's really intended.

commit 09b1d5dc6ce1c9151777f6c4e128a59457704c97 upstream.
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.

commit a1d5ff5651ea592c67054233b14b30bf4452999c upstream.
Properly parse A-MSDUs whose first 6 bytes happen to equal a rfc1042
header. This can occur in practice when the destination MAC address
equals AA:AA:03:00:00:00. More importantly, this simplifies the next
patch to mitigate A-MSDU injection attacks.

Some identifiers have different names between their prototypes
and the kernel-doc markup.
Others need to be fixed, as kernel-doc markups should use this format:
identifier - description
In the specific case of __sta_info_flush(), add a documentation

Pull documentation updates from Mauro Carvalho Chehab:
"A series of patches addressing warnings produced by make htmldocs.
This includes:
- kernel-doc markup fixes
- ReST fixes
- Updates at the build system in order to support newer versions of
the docs build toolchain (Sphinx)
After this series, the number of html build warnings should reduce
significantly, and building with Sphinx 3.1 or later should now be
supported (although it is still recommended to use Sphinx 2.4.4).
As agreed with Jon, I should be sending you a late pull request by the
end of the merge window addressing remaining issues with docs build,
as there are a number of warning fixes that depends on pull requests
that should be happening along the merge window.
The end goal is to have a clean htmldocs build on Kernel 5.10.
PS. It should be noticed that Sphinx 3.0 is not currently supported,
as it lacks support for C domain namespaces. Such feature, needed in
order to document uAPI system calls with Sphinx 3.x, was added only on
Sphinx 3.1"

Currently, before being able to forward a packet between two 802.11s
nodes, both a PLINK handshake is performed upon receiving a beacon and
then later a PREQ/PREP exchange for path discovery is performed on
demand upon receiving a data frame to forward.
When running a mesh protocol on top of an 802.11s interface, like
batman-adv, we do not need the multi-hop mesh routing capabilities of
802.11s and usually set mesh_fwding=0. However, even with mesh_fwding=0
the PREQ/PREP path discovery is still performed on demand. Even though
in this scenario the next hop PREQ/PREP will determine is always the
direct 11s neighbor node.
The new mesh_nolearn parameter allows to skip the PREQ/PREP exchange in
this scenario, leading to a reduced delay, reduced packet buffering and
simplifies HWMP in general.
mesh_nolearn is still rather conservative in that if the packet destination
is not a direct 11s neighbor, it will fall back to PREQ/PREP path
discovery.
For normal, multi-hop 802.11s mesh routing it is usually not advisable
to enable mesh_nolearn as a transmission to a direct but distant neighbor
might be worse than reaching that same node via a more robust /
higher throughput etc. multi-hop path.

The low level driver adds its own opaque information
in the BSS table in the cfg80211_bss structure.
The low level driver may need to signal that this information
is no longer relevant and needs to be recreated.
Add an API to allow the low level driver to do that.
iwlwifi needs this because it keeps there an information about
the firmware's internal clock. This is kept in mac80211's
struct ieee80211_bss::sync_device_ts.
This information is populated while we scan, we add the
internal firmware's clock to each beacon which allows us to
program the firmware correctly after association so that
it'll know when (in terms of its internal clock) the DTIM
and TBTT will happen.
When the firmware is reset this internal clock is reset as
well and ieee80211_bss::sync_device_ts is no longer accurate.
iwlwifi will call this new API any time the firmware is started.

Lockdep reports that we may deadlock because we take the RTNL on
the work struct, but flush it under RTNL. Clearly, it's correct.
In practice, this can happen when doing rfkill on an active device.
Fix this by moving the work struct to the wiphy (registered dev)
layer, and iterate over all the wdevs inside there. This then
means we need to track which one of them has work to do, so we
don't update to the driver for all wdevs all the time.
Also fix a locking bug I noticed while working on this - the
registrations list is iterated as if it was an RCU list, but it
isn't handle that way - and we need to lock now for the update
flag anyway, so remove the RCU.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

====================
One batch of changes, containing:
* hwsim improvements from Jouni and myself, to be able to
test more scenarios easily
* some more HE (802.11ax) support
* some initial S1G (sub 1 GHz) work for fractional MHz channels
* some (action) frame registration updates to help DPP support
* along with other various improvements/fixes

Some bands (S1G) define channels centered on a non-integer
MHz. Give ieee80211_channel and cfg80211_chan_def a
freq_offset component where the final frequency can be
expressed as:
MHZ_TO_KHZ(chan->center_freq) + chan->freq_offset;
Also provide some helper functions to do the frequency
conversion and test for equality.
Retain the existing interface to frequency and channel
conversion helpers, and expose new ones which handle
frequencies in units of KHz.
Some internal functions (net/wireless/chan.c) pass around
a frequency value. Convert these to units of KHz.
mesh, ibss, wext, etc. are currently ignored.

For DPP, there's a need to receive multicast action frames,
but many drivers need a special filter configuration for this.
Support announcing from userspace in the management registration
that multicast RX is required, with an extended feature flag if
the driver handles this.

Almost all drivers below cfg80211 get the API wrong (except for
cfg80211) and are unable to cope with multiple registrations for
the same frame type, which is valid due to the match filter.
This seems to indicate the API is wrong, and we should maintain
the full information in cfg80211 instead of the drivers.
Change the API to no longer inform the driver about individual
registrations and unregistrations, but rather every time about
the entire state of the entire wiphy and single wdev, whenever
it may have changed. This also simplifies the code in cfg80211
as it no longer has to track exactly what was unregistered and
can free things immediately.

Extend cfg80211_rx_unprot_mlme_mgmt() to cover indication of unprotected
Beacon frames in addition to the previously used Deauthentication and
Disassociation frames. The Beacon frame case is quite similar, but has
couple of exceptions: this is used both with fully unprotected and also
incorrectly protected frames and there is a rate limit on the events to
avoid unnecessary flooding netlink events in case something goes wrong.

Drivers that trigger roaming need to know the lifetime of the configured
PMKSA for deciding whether to trigger the full or PMKSA cache based
authentication. The configured PMKSA is invalid after the PMK lifetime
has expired and must not be used after that and the STA needs to
disassociate if the PMK expires. Hence the STA is expected to refresh
the PMK with a full authentication before this happens (e.g., when
reassociating to a new BSS the next time or by performing EAPOL
reauthentication depending on the AKM) to avoid unnecessary
disconnection.
The PMK reauthentication threshold is the percentage of the PMK lifetime
value and indicates to the driver to trigger a full authentication roam
(without PMKSA caching) after the reauthentication threshold time, but
before the PMK timer has expired. Authentication methods like SAE need
to be able to generate a new PMKSA entry without having to force a
disconnection after this threshold timeout. If no roaming occurs between
the reauthentication threshold time and PMK lifetime expiration,
disassociation is still forced.
The new attributes for providing these values correspond to the dot11
MIB variables dot11RSNAConfigPMKLifetime and
dot11RSNAConfigPMKReauthThreshold.
This type of functionality is already available in cases where user
space component is in control of roaming. This commit extends that same
capability into cases where parts or all of this functionality is
offloaded to the driver.
