dc0c18ed22 mac80211: fix scan when operating on DFS channels in ETSI domains
In non-ETSI regulatory domains scan is blocked when operating channel
is a DFS channel. For ETSI, however, once DFS channel is marked as
available after the CAC, this channel will remain available (for some
time) even after leaving this channel.

Therefore a scan can be done without any impact on the availability
of the DFS channel as no new CAC is required after the scan.

Enable scan in mac80211 in these cases.

461c4c2b4c cfg80211: fix a bunch of RCU issues in multi-bssid code
cfg80211_update_notlisted_nontrans() leaves the RCU critical session
too early, while still using nontrans_ssid which is RCU protected. In
addition, it performs a bunch of RCU pointer update operations such
as rcu_access_pointer and rcu_assign_pointer.

The caller, cfg80211_inform_bss_frame_data(), also accesses the RCU
pointer without holding the lock.

Just wrap all of this with bss_lock.

Additionally, in a few places we rely on the driver to init the

c1d3ad84ea cfg80211: Purge frame registrations on iftype change
Currently frame registrations are not purged, even when changing the
interface type.  This can lead to potentially weird situations where
frames possibly not allowed on a given interface type remain registered
due to the type switching happening after registration.

The kernel currently relies on userspace apps to actually purge the
registrations themselves, this is not something that the kernel should
rely on.

Add a call to cfg80211_mlme_purge_registrations() to forcefully remove
any registrations left over prior to switching the iftype.

3cfe91c4c3 cfg80211: always shut down on HW rfkill
When the RFKILL subsystem isn't available, then rfkill_blocked()
always returns false. In the case of hardware rfkill this will
be wrong though, as if the hardware reported being killed then
it cannot operate any longer.

Since we only ever call the rfkill_sync work in this case, just
rename it to rfkill_block and always pass "true" for the blocked
parameter, rather than passing rfkill_blocked().

We rely on the underlying driver to still reject any new attempt
to bring up the device by itself.

2a38075cd0 nl80211: Add support for EDMG channels
802.11ay specification defines Enhanced Directional Multi-Gigabit
(EDMG) STA and AP which allow channel bonding of 2 channels and more.

Introduce new NL attributes that are needed for enabling and
configuring EDMG support.

Two new attributes are used by kernel to publish driver's EDMG
capabilities to the userspace:
NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16
GHz channel(s) that are supported by the driver.
When this attribute is not set it means driver does not support EDMG.
NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth
configurations supported by the driver.

Additional two new attributes are used by the userspace for connect
command and for AP configuration:
NL80211_ATTR_WIPHY_EDMG_CHANNELS
NL80211_ATTR_WIPHY_EDMG_BW_CONFIG

New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver
and used for bitrate calculation that will take into account EDMG
according to the 802.11ay specification.

0d31d4dbf3 Revert "cfg80211: fix processing world regdomain when non modular"
This reverts commit 96cce12ff6 ("cfg80211: fix processing world
regdomain when non modular").

Re-triggering a reg_process_hint with the last request on all events,
can make the regulatory domain fail in case of multiple WiFi modules. On
slower boards (espacially with mdev), enumeration of the WiFi modules
can end up in an intersected regulatory domain, and user cannot set it
with 'iw reg set' anymore.

This is happening, because:
- 1st module enumerates, queues up a regulatory request
- request gets processed by __reg_process_hint_driver():
  - checks if previous was set by CORE -> yes
    - checks if regulator domain changed -> yes, from '00' to e.g. 'US'
      -> sends request to the 'crda'
- 2nd module enumerates, queues up a regulator request (which triggers
  the reg_todo() work)
- reg_todo() -> reg_process_pending_hints() sees, that the last request
  is not processed yet, so it tries to process it again.
  __reg_process_hint driver() will run again, and:
  - checks if the last request's initiator was the core -> no, it was
    the driver (1st WiFi module)
  - checks, if the previous initiator was the driver -> yes
    - checks if the regulator domain changed -> yes, it was '00' (set by
      core, and crda call did not return yet), and should be changed to 'US'

------> __reg_process_hint_driver calls an intersect

Besides, the reg_process_hint call with the last request is meaningless
since the crda call has a timeout work. If that timeout expires, the
first module's request will lost.

b67fd72e84 cfg80211: Fix Extended Key ID key install checks
Fix two shortcomings in the Extended Key ID API:

 1) Allow the userspace to install pairwise keys using keyid 1 without
    NL80211_KEY_NO_TX set. This allows the userspace to install and
    activate pairwise keys with keyid 1 in the same way as for keyid 0,
    simplifying the API usage for e.g. FILS and FT key installs.

 2) IEEE 802.11 - 2016 restricts Extended Key ID usage to CCMP/GCMP
    ciphers in IEEE 802.11 - 2016 "9.4.2.25.4 RSN capabilities".
    Enforce that when installing a key.

0afd425b1b cfg80211: fix duplicated scan entries after channel switch
When associated BSS completes channel switch procedure, its channel
record needs to be updated. The existing mac80211 solution was
extended to cfg80211 in commit 5dc8cdce1d ("mac80211/cfg80211:
update bss channel on channel switch").

However that solution still appears to be incomplete as it may lead
to duplicated scan entries for associated BSS after channel switch.
The root cause of the problem is as follows. Each BSS entry is
included into the following data structures:
- bss list rdev->bss_list
- bss search tree rdev->bss_tree
Updating BSS channel record without rebuilding bss_tree may break
tree search since cmp_bss considers all of the following: channel,
bssid, ssid. When BSS channel is updated, but its location in bss_tree
is not updated, then subsequent search operations may fail to locate
this BSS since they will be traversing bss_tree in wrong direction.
As a result, for scan performed after associated BSS channel switch,
cfg80211_bss_update may add the second entry for the same BSS to both
bss_list and bss_tree, rather then update the existing one.

To summarize, if BSS channel needs to be updated, then bss_tree should
be rebuilt in order to put updated BSS entry into a proper location.

This commit suggests the following straightforward solution:
- if new entry has been already created for BSS after channel switch,
  then use its IEs to update known BSS entry and then remove new
  entry completely
- use rb_erase/rb_insert_bss reinstall updated BSS in bss_tree
- for nontransmit BSS entry, the whole transmit BSS hierarchy
  is updated

e6f4051123 {nl,mac}80211: fix interface combinations on crypto controlled devices
Commit 33d915d9e8 ("{nl,mac}80211: allow 4addr AP operation on
crypto controlled devices") has introduced a change which allows
4addr operation on crypto controlled devices (ex: ath10k). This
change has inadvertently impacted the interface combinations logic
on such devices.

General rule is that software interfaces like AP/VLAN should not be
listed under supported interface combinations and should not be
considered during validation of these combinations; because of the
aforementioned change, AP/VLAN interfaces(if present) will be checked
against interfaces supported by the device and blocks valid interface
combinations.

Consider a case where an AP and AP/VLAN are up and running; when a
second AP device is brought up on the same physical device, this AP
will be checked against the AP/VLAN interface (which will not be
part of supported interface combinations of the device) and blocks
second AP to come up.

Add a new API cfg80211_iftype_allowed() to fix the problem, this
API works for all devices with/without SW crypto control.

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.

028db3e290 Revert "Merge tag 'keys-acl-20190703' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs"
This reverts merge 0f75ef6a9c (and thus
effectively commits

   7a1ade8475 ("keys: Provide KEYCTL_GRANT_PERMISSION")
   2e12256b9a ("keys: Replace uid/gid/perm permissions checking with an ACL")

that the merge brought in).

It turns out that it breaks booting with an encrypted volume, and Eric
biggers reports that it also breaks the fscrypt tests [1] and loading of
in-kernel X.509 certificates [2].

The root cause of all the breakage is likely the same, but David Howells
is off email so rather than try to work it out it's getting reverted in
order to not impact the rest of the merge window.

Merge tag 'keys-acl-20190703' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull keyring ACL support from David Howells:
 "This changes the permissions model used by keys and keyrings to be
  based on an internal ACL by the following means:

   - Replace the permissions mask internally with an ACL that contains a
     list of ACEs, each with a specific subject with a permissions mask.
     Potted default ACLs are available for new keys and keyrings.

     ACE subjects can be macroised to indicate the UID and GID specified
     on the key (which remain). Future commits will be able to add
     additional subject types, such as specific UIDs or domain
     tags/namespaces.

     Also split a number of permissions to give finer control. Examples
     include splitting the revocation permit from the change-attributes
     permit, thereby allowing someone to be granted permission to revoke
     a key without allowing them to change the owner; also the ability
     to join a keyring is split from the ability to link to it, thereby
     stopping a process accessing a keyring by joining it and thus
     acquiring use of possessor permits.

   - Provide a keyctl to allow the granting or denial of one or more
     permits to a specific subject. Direct access to the ACL is not
     granted, and the ACL cannot be viewed"
