There is a crash when adding one of the lan966x interfaces under a lag
interface. The issue can be reproduced like this:
ip link add name bond0 type bond miimon 100 mode balance-xor
ip link set dev eth0 master bond0
The reason is because when adding a interface under the lag it would go
through all the ports and try to figure out which other ports are under
that lag interface. And the issue is that lan966x can have ports that are
NULL pointer as they are not probed. So then iterating over these ports
it would just crash as they are NULL pointers.
The fix consists in actually checking for NULL pointers before accessing
something from the ports. Like we do in other places.
Fixes: cabc9d49333d ("net: lan966x: Add lag support for lan966x")

add more code into this function.
Since we are passing the address of the filter base to free the

is always at the beginning of the structure.

While individual filter structures are allocated as needed, there is an
array to keep track of the software filter IDs that we allocate ahead
of time. Rather than relying on a fixed maximum filter count to
allocate this array, get the maximum from the firmware when available.
Move these filter related maximum counts queried from the firmware to the
bnxt_hw_resc struct. If the firmware is not providing these maximum
counts, fall back to the hard-coded constant.

Pull EFI fixes from Ard Biesheuvel:
"The only notable change here is the patch that changes the way we deal
with spurious errors from the EFI memory attribute protocol. This will
be backported to v6.6, and is intended to ensure that we will not
paint ourselves into a corner when we tighten this further in order to
comply with MS requirements on signed EFI code.
Note that this protocol does not currently exist in x86 production
systems in the field, only in Microsoft's fork of OVMF, but it will be
mandatory for Windows logo certification for x86 PCs in the future.
- Tighten ELF relocation checks on the RISC-V EFI stub
- Give up if the new EFI memory attributes protocol fails spuriously
on x86
- Take care not to place the kernel in the lowest 16 MB of DRAM on

On early detection of wwan device in fastboot mode, driver sets
up CLDMA0 HW tx/rx queues for raw data transfer and then create
fastboot port to userspace.
Application can use this port to flash firmware and collect
core dump by fastboot protocol commands.
E.g., flash firmware through fastboot port:
- "download:%08x": write data to memory with the download size.
- "flash:%s": write the previously downloaded image to the named partition.
- "reboot": reboot the device.

After commit 4a032827daa8 ("of: property: Simplify of_link_to_phandle()"),
remote-endpoint properties created a fwnode link from the consumer device
to the supplier endpoint. This is a tiny bit inefficient (not buggy) when
trying to create device links or detecting cycles. So, improve this the
same way we improved finding the consumer of a remote-endpoint property.

We have a more accurate function to find the right consumer of a
remote-endpoint property instead of searching for a parent with
compatible string property. So, use that instead. While at it, make the
code to find the consumer a bit more flexible and based on the property
being parsed.
Fixes: f7514a663016 ("of: property: fw_devlink: Add support for remote-endpoint")

Regardless of whether the original message body or formatted userdata
exceeds the MAX_PRINT_CHUNK, append userdata to the netconsole message
starting with the first chunk that has available space after writing the
body.

Append userdata to outgoing unfragmented (<1000 bytes) netconsole messages.
When sending messages the userdata string is already formatted and stored
in netconsole_target->userdata_complete.
Always write the outgoing message to buf, so userdata can be appended in
a standard fashion. This is a change from only using buf when the
release needs to be prepended to the message.

Store a formatted string for userdata that will be appended to netconsole
messages. The string has a capacity of 4KB, as calculated by the userdatum
entry length of 256 bytes and a max of 16 userdata entries.
Update the stored netconsole_target->userdata_complete string with the new
formatted userdata values when a userdatum is created, edited, or
removed. Each userdata entry contains a trailing newline, which will be
formatted as such in netconsole messages::
6.7.0-rc8-virtme,12,500,1646292204,-;test
release=foo
something=bar
6.7.0-rc8-virtme,12,500,1646292204,-;another test
release=foo
something=bar
Enforcement of MAX_USERDATA_ITEMS is done in userdatum_make_item;
update_userdata will not check for this case but will skip any userdata
children over the limit of MAX_USERDATA_ITEMs.
If a userdata entry/dir is created but no value is provided, that entry
will be skipped. This is in part because update_userdata() can't be
called in userdatum_make_item() since the item will not have been added
to the userdata config_group children yet. To preserve the experience of
adding an empty userdata that doesn't show up in the netconsole
messages, purposefully skip empty userdata items even when
update_userdata() can be called.

Create configfs machinery for netconsole userdata appending, which depends
on CONFIG_NETCONSOLE_DYNAMIC (for configfs interface). Add a userdata
config_group to netconsole_target for managing userdata entries as a tree
under the netconsole configfs subsystem. Directory names created under the
userdata directory become userdatum keys; the userdatum value is the
content of the value file.
Include the minimum-viable-changes for userdata configfs config_group.
init_target_config_group() ties in the complete configfs machinery to
avoid unused func/variable errors during build. Initializing the
netconsole_target->group is moved to init_target_config_group, which
will also init and add the userdata config_group.
Each userdatum entry has a limit of 256 bytes (54 for
the key/directory, 200 for the value, and 2 for '=' and '\n'
characters), which is enforced by the configfs functions for updating
the userdata config_group.
When a new netconsole_target is created, initialize the userdata
config_group and add it as a default group for netconsole_target
config_group, allowing the userdata configfs sub-tree to be presented
in the netconsole configfs tree under the userdata directory.

In order to support a nested userdata config_group in later patches,
use a config_group for netconsole_target instead of a
config_item. It's a no-op functionality-wise, since
config_group maintains all features of a config_item via the cg_item
member.

TOE has hardware support for calculating IP header and TCP/UDP/ICMP
checksum for both IPv4 and IPv6.
Add Tx checksum offload supported by TOE for IPv4 and TCP/UDP.
For Tx, the result of checksum calculation is set to the checksum field of
each IPv4 Header/TCP/UDP/ICMP of ethernet frames. For the unsupported
frames, those fields are not changed. If a transmission frame is an UDPv4
frame and its checksum value in the UDP header field is 0x0000, TOE does
not calculate checksum for UDP part of this frame as it is optional
function as per standards.
We can test this functionality by the below commands
ethtool -K eth0 tx on --> to turn on Tx checksum offload
ethtool -K eth0 tx off --> to turn off Tx checksum offload

TOE has hardware support for calculating IP header and TCP/UDP/ICMP
checksum for both IPv4 and IPv6.
Add Rx checksum offload supported by TOE for IPv4 and TCP/UDP protocols.
For Rx, the 4-byte result of checksum calculation is attached to the
Ethernet frames.First 2-bytes is result of IPv4 header checksum and next
2-bytes is TCP/UDP/ICMP checksum.
If a frame does not have checksum error, 0x0000 is attached as checksum
calculation result. For unsupported frames 0xFFFF is attached as checksum
calculation result. In case of an IPv6 packet, IPv4 checksum is always set
to 0xFFFF.
We can test this functionality by the below commands
ethtool -K eth0 rx on --> to turn on Rx checksum offload
ethtool -K eth0 rx off --> to turn off Rx checksum offload

The variable capability is being assigned a value that is never
read and is being re-assigned later. The assignment is redundant and
can be removed. Also remove empty line before assignment to capability.
