commit 2d9463083ce92636a1bdd3e30d1236e3e95d859e upstream.
syzbot discovered a bug in which an OOB access was being made because
an unsuitable key_idx value was wrongly considered to be acceptable
while deleting a key in nl80211_del_key().Since we don't know the cipher at the time of deletion, if
cfg80211_validate_key_settings() were to be called directly in
nl80211_del_key(), even valid keys would be wrongly determined invalid,
and deletion wouldn't occur correctly.
For this reason, a new function - cfg80211_valid_key_idx(), has been
created, to determine if the key_idx value provided is valid or not.
cfg80211_valid_key_idx() is directly called in 2 places -
nl80211_del_key(), and cfg80211_validate_key_settings().Reported-by: syzbot+49d4cab497c2142ee170@syzkaller.appspotmail.com

Two minor conflicts:
1) net/ipv4/route.c, adding a new local variable while
moving another local variable and removing it's
initial assignment.2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
One pretty prints the port mode differently, whilst another
changes the driver to try and obtain the port mode from
the port node rather than the switch node.Signed-off-by: David S. Miller

As said by Linus:
A symmetric naming is only helpful if it implies symmetries in use.
Otherwise it's actively misleading.In "kzalloc()", the z is meaningful and an important part of what the
caller wants.In "kzfree()", the z is actively detrimental, because maybe in the
future we really _might_ want to use that "memfill(0xdeadbeef)" or
something. The "zero" part of the interface isn't even _relevant_.The main reason that kzfree() exists is to clear sensitive information
that should not be leaked to other future users of the same memory
objects.Rename kzfree() to kfree_sensitive() to follow the example of the recently
added kvfree_sensitive() and make the intention of the API more explicit.
In addition, memzero_explicit() is used to clear the memory to make sure
that it won't get optimized away by the compiler.The renaming is done by using the command sequence:
git grep -w --name-only kzfree |\
xargs sed -i 's/kzfree/kfree_sensitive/'followed by some editing of the kfree_sensitive() kerneldoc and adding
a kzfree backward compatibility macro in slab.h.[akpm@linux-foundation.org: fs/crypto/inline_crypt.c needs linux/slab.h]

The 6GHz band does not have regulatory approval yet, but things are
moving forward. However, that has led to a change in the channelization
of the 6GHz band which has been accepted in the 11ax specification. It
also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it.This change is primarily thrown in to discuss how to deal with it.

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.

Somehow we missed this for a long time, but similar to the extended
NSS support in VHT capabilities, we need to have this in Operating
Mode notification.Implement it by
* parsing the 160/80+80 bit there and setting the bandwidth
appropriately
* having callers of ieee80211_get_vht_max_nss() pass in the current
max NSS value as received in the operating mode notification in
order to modify it appropriately depending on the extended NSS
bits.This updates all drivers that use it, i.e. only iwlwifi/mvm.

IEEE P802.11-REVmd/D3.0 adds support for protecting Beacon frames using
a new set of keys (BIGTK; key index 6..7) similarly to the way
group-addressed Robust Management frames are protected (IGTK; key index
4..5). Extend cfg80211 and nl80211 to allow the new BIGTK to be

the new key index values to avoid array overflows in driver
implementations and also to indicate to user space when this
functionality is available.Signed-off-by: Jouni Malinen

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.Cc: stable@vger.kernel.org

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_CONFIGNew rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver

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

Commit 33d915d9e8ce ("{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.Signed-off-by: Manikanta Pubbisetty
