[ Upstream commit a64b6a25dd ]
If the userland switches back-and-forth between NL80211_IFTYPE_OCB and
NL80211_IFTYPE_ADHOC via send_msg(NL80211_CMD_SET_INTERFACE), there is a
chance where the cleanup cfg80211_leave_ocb() is not called. This leads
to initialization of in-use memory (e.g. init u.ibss while in-use by
u.ocb) due to a shared struct/union within ieee80211_sub_if_data:
struct ieee80211_sub_if_data {
...
union {
struct ieee80211_if_ap ap;
struct ieee80211_if_vlan vlan;
struct ieee80211_if_managed mgd;
struct ieee80211_if_ibss ibss; // <- shares address
struct ieee80211_if_mesh mesh;
struct ieee80211_if_ocb ocb; // <- shares address
struct ieee80211_if_mntr mntr;
struct ieee80211_if_nan nan;
} u;
...
}
Therefore add handling of otype == NL80211_IFTYPE_OCB, during
cfg80211_change_iface() to perform cleanup when leaving OCB mode.

commit 2b8a1fee34 upstream.
Mitigate A-MSDU injection attacks (CVE-2020-24588) by detecting if the
destination address of a subframe equals an RFC1042 (i.e., LLC/SNAP)
header, and if so dropping the complete A-MSDU frame. This mitigates
known attacks, although new (unknown) aggregation-based attacks may
remain possible.
This defense works because in A-MSDU aggregation injection attacks, a
normal encrypted Wi-Fi frame is turned into an A-MSDU frame. This means
the first 6 bytes of the first A-MSDU subframe correspond to an RFC1042
header. In other words, the destination MAC address of the first A-MSDU
subframe contains the start of an RFC1042 header during an aggregation
attack. We can detect this and thereby prevent this specific attack.
For details, see Section 7.2 of "Fragment and Forge: Breaking Wi-Fi
Through Frame Aggregation and Fragmentation".
Note that for kernel 4.9 and above this patch depends on "mac80211:
properly handle A-MSDUs that start with a rfc1042 header". Otherwise
this patch has no impact and attacks will remain possible.

commit a1d5ff5651 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.

Drivers supporting 4096-QAM rates as a vendor extension in HE mode need
to update the correct rate info to userspace while using 4096-QAM (MCS12
and MCS13) in HE mode. Add support to calculate bitrates of HE-MCS12 and
HE-MCS13 which represent the 4096-QAM modulation schemes. The MCS12 and
MCS13 bitrates are defined in IEEE P802.11be/D0.1.
In addition, scale up the bitrates by 3*2048 in order to accommodate
calculations for the new MCS12 and MCS13 rates without losing fraction
values.

commit 2d9463083c 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().

[rewrite commit message, hard-code channel 2]
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
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.

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.
I noticed ath11k adding 6G support with old channelization and ditto
for iw. It probably involves changes in hostapd as well.

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.

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

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.

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.

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.

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.

The bits of Rx MCS Map in VHT capability were enumerated
with index transform - index i -> (i + 1) bit => nss i. BUG!
while it should be - index i -> (i + 1) bit => (i + 1) nss.
The bug was exposed in commit a53b2a0b12 ("iwlwifi: mvm: implement VHT

When building with -Wsometimes-uninitialized, Clang warns:
net/wireless/util.c:1223:11: warning: variable 'result' is used
uninitialized whenever 'if' condition is false
[-Wsometimes-uninitialized]
Clang can't evaluate at this point that WARN(1, ...) always returns true
because __ret_warn_on is defined as !!(condition), which isn't
immediately evaluated as 1. Change this branch to else so that it's
clear to Clang that we intend to bail out here.

We currently have a number of helpers to find elements that just
return a u8 *, change those to return a struct element and add
inlines to deal with the u8 * compatibility.
Note that the match behaviour is changed to start the natch at
the data, so conversion from _ie_match to _elem_match need to
be done carefully.

This function was modified to support the information element extension
case (WLAN_EID_EXTENSION) in a manner that would result in an infinite
loop when going through set of IEs that include WLAN_EID_RIC_DATA and
contain an IE that is in the after_ric array. The only place where this
can currently happen is in mac80211 ieee80211_send_assoc() where
ieee80211_ie_split_ric() is called with after_ric[].
This can be triggered by valid data from user space nl80211
association/connect request (i.e., requiring GENL_UNS_ADMIN_PERM). The
only known application having an option to include WLAN_EID_RIC_DATA in
these requests is wpa_supplicant and it had a bug that prevented this
specific contents from being used (and because of that, not triggering
this kernel bug in an automated test case ap_ft_ric) and now that this
bug is fixed, it has a workaround to avoid this kernel issue.
WLAN_EID_RIC_DATA is currently used only for testing purposes, so this
does not cause significant harm for production use cases.
