With basic HE radiotap, we can check data rate in sniffer data. To store
the radiotap data, we reserve headroom of aligned 64 bytes, and then
update HE radiotap in monitor mode, so it doesn't affect performance in
normal mode.

For running with mac80211 channel context ops and using only as monitor,
we need to enable WANT_MONITOR_VIF to let mac80211 process virtual monitor
interface. Then, we are able to set channel on the monitor from user space.

This patch fixes slab-out-of-bounds reads in brcmfmac that occur in
brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count
value of channel specifications provided by the device is greater than
the length of 'list->element[]', decided by the size of the 'list'
allocated with kzalloc(). The patch adds checks that make the functions
free the buffer and return -EINVAL if that is the case. Note that the
negative return is handled by the caller, brcmf_setup_wiphybands() or
brcmf_cfg80211_attach().
Found by a modified version of syzkaller.

For SDIO/USB interface, since the tranferring speed is slower than
that in PCIE, it may have race condition when the driver sets down
H2C command to the FW.
In the function rtw_fw_send_h2c_command, before the patch, box_reg
is written first, then box_ex_reg is written. FW starts to work and
fetch the value of box_ex_reg, when the most significant byte of
box_reg(4 bytes) is written. Meanwhile, for SDIO/USB interface,
since the transferring speed is slow, the driver is still in writing
the new value of box_ex_reg through the bus, and FW may get the
wrong value of box_ex_reg at the moment.
To prevent the above driver/FW racing situation, box_ex_reg is
written first then box_reg. Furthermore, it is written in 4 bytes at
a time, instead of written in one byte one by one. It can increase
the speed for SDIO/USB interface.

Zero-length arrays are deprecated[1] and are being replaced with
flexible array members in support of the ongoing efforts to tighten the
FORTIFY_SOURCE routines on memcpy(), correctly instrument array indexing
with UBSAN_BOUNDS, and to globally enable -fstrict-flex-arrays=3.
Replace zero-length array with flexible-array member.

In a SoC based solution, it would be useful to know the versions of the
various binary firmware blobs the system is running on. On a QCOM based
SoC, this info can be obtained from socinfo debugfs infrastructure. For
this to work, respective subsystem drivers have to export the firmware
version information to an SMEM based version information table.
Having firmware version information at one place will help quickly
figure out the firmware versions of various subsystems on the device
instead of going through builds/logs in an event of a system crash.
Fill WLAN firmware version information in SMEM version table to be
printed as part of socinfo debugfs infrastructure on a Qualcomm based
SoC.
This change is applicable only for SNOC/QMI based targets.
Example:
cat /sys/kernel/debug/qcom_socinfo/cnss/name
QC_IMAGE_VERSION_STRING=WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1

Prefer struct_size() over open-coded versions of idiom:
sizeof(struct-with-flex-array) + sizeof(typeof-flex-array-elements) * count
where count is the max number of items the flexible array is supposed to
contain.
In this particular case, in the open-coded version sizeof(typeof-flex-array-elements)
is implicit in _count_ because the type of the flex array data is u8:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h:941:
941 struct brcmf_dload_data_le {

rxrpc: Fix oops and missing config conditionals
The patches that were pulled into net-next previously[1] had some issues
that this patchset fixes:
(1) Fix missing IPV6 config conditionals.
(2) Fix an oops caused by calling udpv6_sendmsg() directly on an AF_INET
socket.
(3) Fix the validation of network addresses on entry to socket functions
so that we don't allow an AF_INET6 address if we've selected an
AF_INET transport socket.

Dan Carpenter reported that Smatch found an instance where a pointer
which had previously been assumed could be null (as indicated by a
null check) was later dereferenced without a similar check.
In practice this doesn't lead to a problem because currently the
pointers used are all non-null. Nevertheless this patch addresses
the reported problem.
In addition, I spotted another bug that arose in the same commit.
When the command to initialize a routing table memory region was
added, the number of entries computed for the non-hashed table
was wrong (it ended up being a Boolean rather than the count
intended). This bug is fixed here as well.

sctp: support vrf processing
This patchset adds the VRF processing in SCTP. Simliar to TCP/UDP,
it includes socket bind and socket/association lookup changes.
For socket bind change, it allows sockets to bind to a VRF device
and allows multiple sockets with the same IP and PORT to bind to
different interfaces in patch 1-3.
For socket/association lookup change, it adds dif and sdif check
in both asoc and ep lookup in patch 4 and 5, and when binding to
nodev, users can decide if accept the packets received from one
l3mdev by setup a sysctl option in patch 6.
Note with VRF support, in a netns, an association will be decided
by src ip + src port + dst ip + dst port + bound_dev_if, and it's
possible for ss to have:
State Local Address:Port Peer Address:Port
ESTAB 192.168.1.2%vrf-s1:1234
`- ESTAB 192.168.1.2%veth1:1234 192.168.1.1:1234
ESTAB 192.168.1.2%vrf-s2:1234
`- ESTAB 192.168.1.2%veth2:1234 192.168.1.1:1234
See the selftest in patch 7 for more usage.
Also, thanks Carlo for testing this patch series on their use.
v1->v2:
- In Patch 5, move sctp_sk_bound_dev_eq() definition to net/sctp/
input.c to avoid a build error when IP_SCTP is disabled, as Paolo
suggested.
- In Patch 7, avoid one sleep by disabling the IPv6 dad, and remove
another sleep by using ss to check if the server's ready, and also
delete two unncessary sleeps in sctp_hello.c, as Paolo suggested.

This patch at first adds a pernet global l3mdev_accept to decide if it
accepts the packets from a l3mdev when a SCTP socket doesn't bind to
any interface. It's set to 1 to avoid any possible incompatible issue,
and in next patch, a sysctl will be introduced to allow to change it.
Then similar to inet/udp_sk_bound_dev_eq(), sctp_sk_bound_dev_eq() is
added to check either dif or sdif is equal to sk_bound_dev_if, and to
check sid is 0 or l3mdev_accept is 1 if sk_bound_dev_if is not set.
This function is used to match a association or a endpoint, namely
called by sctp_addrs_lookup_transport() and sctp_endpoint_is_match().

net: ipa: change GSI firmware load specification
Currently, GSI firmware must be loaded for IPA before it can be
used--either by the modem, or by the AP. New hardware supports a
third option, with the bootloader taking responsibility for loading
GSI firmware. In that case, neither the AP nor the modem needs to
do that.
The first patch in this series deprecates the "modem-init" Device
Tree property in the IPA binding, using a new "qcom,gsi-loader"
property instead. The second and third implement logic in the code
to support either the "old" or the "new" way of specifying how GSI
firmware is loaded.
The last two patches implement a new value for the "qcom,gsi-loader"
property. If the value is "skip", neither the AP nor modem needs to
load the GSI firmware. The first of these patches implements the
change in the IPA binding; the second implements it in the code.

the AP or modem is the GSI firmware loader, respectively.
For legacy systems, the new property will not exist, and the

GSI firmware for IPA must be loaded during initialization, either by

whether the Boolean modem-init property is present.
Instead, use a new property with an enumerated value to indicate
explicitly how GSI firmware gets loaded. With this in place, a
third approach can be added in an upcoming patch.
The new qcom,gsi-loader property has two defined values:
- self: The AP loads GSI firmware
- modem: The modem loads GSI firmware
The modem-init property must still be supported, but is now marked
deprecated.
Update the example so it represents the SC7180 SoC, and provide
examples for the qcom,gsi-loader, memory-region, and firmware-name

====================
Implement devlink-rate API and extend it
This patch series implements devlink-rate for ice driver. Unfortunately
current API isn't flexible enough for our use case, so there is a need to
extend it. Some functions have been introduced to enable the driver to
export current Tx scheduling configuration.
Pasting justification for this series from commit implementing devlink-rate
in ice driver(that is a part of this series):
There is a need to support modification of Tx scheduler tree, in the
ice driver. This will allow user to control Tx settings of each node in
the internal hierarchy of nodes. As a result user will be able to use
Hierarchy QoS implemented entirely in the hardware.
This patch implemenents devlink-rate API. It also exports initial
default hierarchy. It's mostly dictated by the fact that the tree
can't be removed entirely, all we can do is enable the user to modify
it. For example root node shouldn't ever be removed, also nodes that
have children are off-limits.
Example initial tree with 2 VF's:
[root@fedora ~]# devlink port function rate show
pci/0000:4b:00.0/node_27: type node parent node_26
pci/0000:4b:00.0/node_26: type node parent node_0

pci/0000:4b:00.0/1: type leaf parent node_27
pci/0000:4b:00.0/2: type leaf parent node_27
Let me visualize part of the tree:
+---------+
| node_0 |
+---------+
|
+----v----+
| node_26 |
+----+----+
|
+----v----+
| node_27 |
+----+----+
|
|-----------------|
+----v----+ +----v----+
| VF 1 | | VF 2 |
+----+----+ +----+----+
So at this point there is a couple things that can be done.
For example we could only assign parameters to VF's.
[root@fedora ~]# devlink port function rate set pci/0000:4b:00.0/1 \
tx_max 5Gbps
This would cap the VF 1 BW to 5Gbps.
But let's say you would like to create a completely new branch.
This can be done like this:
[root@fedora ~]# devlink port function rate add \
pci/0000:4b:00.0/node_custom parent node_0
[root@fedora ~]# devlink port function rate add \
pci/0000:4b:00.0/node_custom_1 parent node_custom
[root@fedora ~]# devlink port function rate set \
pci/0000:4b:00.0/1 parent node_custom_1
This creates a completely new branch and reassigns VF 1 to it.
A number of parameters is supported per each node: tx_max, tx_share,
tx_priority and tx_weight.
