Thomas Pedersen d2b7588a47 nl80211: support S1G capability overrides in assoc
NL80211_ATTR_S1G_CAPABILITY can be passed along with
NL80211_ATTR_S1G_CAPABILITY_MASK to NL80211_CMD_ASSOCIATE
to indicate S1G capabilities which should override the
hardware capabilities in eg. the association request.

Thomas Pedersen 37050e3ab0 ieee80211: redefine S1G bits with GENMASK
The S1G capability fields were defined by ORing BITS()
together, and expecting a custom macro to use the _SHIFT
definitions. Use the Linux kernel GENMASK for the
definitions now, and FIELD_{GET,PREP} to access the fields
in the future.

Take the chance to rename eg. S1G_CAPAB_B0 to the more
compact S1G_CAP0.

Jouni Malinen 4e56cde15f mac80211: Handle special status codes in SAE commit
SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK
(WFA) options. Those extensions use special status code values in the
SAE commit messages (Authentication frame with transaction sequence
number 1) to identify which extension is in use. mac80211 was
interpreting those new values as the AP denying authentication and that
resulted in failure to complete SAE authentication in some cases.

Fix this by adding exceptions for the new status code values 126 and
127.

xdp_umem.c had overlapping changes between the 64-bit math fix
for the calculation of npgs and the removal of the zerocopy
memory type which got rid of the chunk_size_nohdr member.

The mlx5 Kconfig conflict is a case where we just take the
net-next copy of the Kconfig entry dependency as it takes on
the ESWITCH dependency by one level of indirection which is
what the 'net' conflicting change is trying to ensure.

Shaul Triebitz 3b3ec3d52e mac80211: check the correct bit for EMA AP
An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set
bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec).
So the *3rd* bit of the 10th byte should be checked.
Also, in one place, the wrong byte was checked.
(cfg80211_find_ie returns a pointer to the beginning of the IE,
 so the data really starts at ie[2], so the 10th byte
 should be ie[12]. To avoid this confusion, use cfg80211_find_elem
 instead).

Gustavo A. R. Silva 396fba0a59 cfg80211: Replace zero-length array with flexible-array
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.

Johannes Berg 9166cc4976 mac80211: implement Operating Mode Notification extended NSS support
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.

commit 08a5bdde38 ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED")
Fixed a bug where we failed to take into account a

there is at least one more bug in
ieee80211_sta_tx_notify(), introduced in
commit 7b6ddeaf27 ("mac80211: use QoS NDP for AP probing"),
where we forgot to check for the QoS variant and so
assumed the QoS nullfunc frame never went out

Fix this by adding a helper ieee80211_is_any_nullfunc()
which consolidates the check for non-QoS and QoS nullfunc
frames. Replace existing compound conditionals and add a
couple more missing checks for QoS variant.

Most likely the last set of patches for 5.1. WPA3 support to ath10k
 and qtnfmac. FTM support to iwlwifi and ath10k. And of course other
 new features and bugfixes.
 
 wireless-drivers was merged due to dependency in mt76.
 
 Major changes:
 
 iwlwifi
 
 * HE radiotap
 
 * FTM (Fine Timing Measurement) initiator and responder implementation
 
 * bump supported firmware API to 46
 
 * VHT extended NSS support
 
 * new PCI IDs for 9260 and 22000 series

Merge tag 'wireless-drivers-next-for-davem-2019-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
wireless-drivers-next patches for 5.1

Most likely the last set of patches for 5.1. WPA3 support to ath10k
and qtnfmac. FTM support to iwlwifi and ath10k. And of course other
new features and bugfixes.

wireless-drivers was merged due to dependency in mt76.

Major changes:

iwlwifi

* HE radiotap

* FTM (Fine Timing Measurement) initiator and responder implementation

* bump supported firmware API to 46

* VHT extended NSS support

* new PCI IDs for 9260 and 22000 series

ath10k

* change QMI interface to support the new (and backwards incompatible)
  interface from HL3.1 and used in recent HL2.0 branch firmware
  releases

* support WPA3 with WCN3990

* support for mac80211 airtime fairness based on transmit rate
  estimation, the firmware needs to support WMI_SERVICE_PEER_STATS to
  enable this

* report transmit airtime to mac80211 with firmwares having
  WMI_SERVICE_REPORT_AIRTIME feature, this to have more accurate
  airtime fairness based on real transmit time (instead of just
  estimated from transmit rate)

* support Fine Timing Measurement (FTM) responder role

* add dynamic VLAN support with firmware having WMI_SERVICE_PER_PACKET_SW_ENCRYPT

* switch to use SPDX license identifiers

ath

* add new country codes for US

brcmfmac

* support monitor frames with the hardware/ucode header

qtnfmac

* enable WPA3 SAE and OWE support

mt76

* beacon support for USB devices (mesh+ad-hoc only)

rtlwifi

* convert to use SPDX license identifiers

libertas_tf

* get the MAC address before registering the device

Sara Sharon ee145775c1 mac80211: support max channel switch time element
2018 REVmd of the spec introduces the max channel switch time
element which is optionally included in beacons/probes when there
is a channel switch / extended channel switch element.
The value represents the maximum delay between the time the AP
transmitted the last beacon in current channel and the expected
time of the first beacon in the new channel, in TU.

Parse the value and pass it to the driver.

Jouni Malinen 7388afe091 cfg80211: Use const more consistently in for_each_element macros
Enforce the first argument to be a correct type of a pointer to struct
element and avoid unnecessary typecasts from const to non-const pointers
(the change in validate_ie_attr() is needed to make this part work). In
addition, avoid signed/unsigned comparison within for_each_element() and
mark struct element packed just in case.

Johannes Berg 0f3b07f027 cfg80211: add and use strongly typed element iteration macros
Rather than always iterating elements from frames with pure
u8 pointers, add a type "struct element" that encapsulates
the id/datalen/data format of them.

Then, add the element iteration macros
 * for_each_element
 * for_each_element_id
 * for_each_element_extid

which take, as their first 'argument', such a structure and
iterate through a given u8 array interpreting it as elements.

While at it and since we'll need it, also add
 * for_each_subelement
 * for_each_subelement_id
 * for_each_subelement_extid

which instead of taking data/length just take an outer element
and use its data/datalen.

Also add for_each_element_completed() to determine if any of
the loops above completed, i.e. it was able to parse all of
the elements successfully and no data remained.

Use for_each_element_id() in cfg80211_find_ie_match() as the
first user of this.
