dev->nd_net can change, readers should either
use rcu_read_lock() or RTNL.

When using Rust on the x86 architecture, we are currently using the
unstable target.json feature to specify the compilation target. Rustc is
going to change how softfloat is specified in the target.json file on
x86, thus update generate_rust_target.rs to specify softfloat using the
new option.
Note that if you enable this parameter with a compiler that does not
recognize it, then that triggers a warning but it does not break the
build.
[ For future reference, this solves the following error:
RUSTC L rust/core.o
error: Error loading target specification: target feature
`soft-float` is incompatible with the ABI but gets enabled in
target spec. Run `rustc --print target-list` for a list of
built-in targets

The uretprobe syscall is implemented as a performance enhancement on
x86_64 by having the kernel inject a call to it on function exit; User
programs cannot call this system call explicitly.
As such, this syscall is considered a kernel implementation detail and
should not be filtered by seccomp.
Enhance the seccomp bpf test suite to check that uretprobes can be
attached to processes without the killing the process regardless of
seccomp policy.

When attaching uretprobes to processes running inside docker, the attached
process is segfaulted when encountering the retprobe.
The reason is that now that uretprobe is a system call the default seccomp
filters in docker block it as they only allow a specific set of known
syscalls. This is true for other userspace applications which use seccomp
to control their syscall surface.
Since uretprobe is a "kernel implementation detail" system call which is
not used by userspace application code directly, it is impractical and
there's very little point in forcing all userspace applications to
explicitly allow it in order to avoid crashing tracked processes.
Pass this systemcall through seccomp without depending on configuration.
Note: uretprobe is currently only x86_64 and isn't expected to ever be
supported in i386.

Commit 1db806ec06b7 ("PCI/ASPM: Save parent L1SS config in
pci_save_aspm_l1ss_state()") aimed to perform L1SS config save for both the
Upstream Port and its upstream bridge when handling an Upstream Port, which
matches what the L1SS restore side does. However, parent->state_saved can
be set true at an earlier time when the upstream bridge saved other parts
of its state. Then later when attempting to save the L1SS config while
handling the Upstream Port, parent->state_saved is true in
pci_save_aspm_l1ss_state() resulting in early return and skipping saving
bridge's L1SS config because it is assumed to be already saved. Later on
restore, junk is written into L1SS config which causes issues with some
devices.
Remove parent->state_saved check and unconditionally save L1SS config also
for the upstream bridge from an Upstream Port which ought to be harmless
from correctness point of view. With the Upstream Port check now present,
saving the L1SS config more than once for the bridge is no longer a problem
(unlike when the parent->state_saved check got introduced into the fix
during its development).

In [2] it was pointed out that parts of setarch weren't working
properly on alpha because it has it's own SET_PERSONALITY
implementation. In the discussion that followed Richard Henderson
pointed out that the 32bit pointer support for alpha was never
completed.
Fix this by removing alpha's 32bit pointer support.
As a bit of paranoia refuse to execute any alpha binaries that have
the EF_ALPHA_32BIT flag set. Just in case someone somewhere has
binaries that try to use alpha's 32bit pointer support.

Other, non DAI copier widgets could have the same stream name (sname) as
the ALH copier and in that case the copier->data is NULL, no alh_data is
attached, which could lead to NULL pointer dereference.
We could check for this NULL pointer in sof_ipc4_prepare_copier_module()
and avoid the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai()
will miscalculate the ALH device count, causing broken audio.
The correct fix is to harden the matching logic by making sure that the
1. widget is a DAI widget - so dai = w->private is valid
2. the dai (and thus the copier) is ALH copier

For systems which load firmware on the cs35l41 which use ACPI, the
_SUB value is used to differentiate firmware and tuning files for the
individual systems. In the case where a system does not have a _SUB
defined in ACPI node for cs35l41, there needs to be a fallback to
allow the files for that system to be differentiated. Since all
ACPI nodes for cs35l41 should have a HID defined, the HID should be a
safe option.

This reverts commit 8865d22656b4, which caused breakage for platforms
which are not using xgmac2 or gmac4. Only these two cores have the
capability of providing the FIFO sizes from hardware capability fields
(which are provided in priv->dma_cap.[tr]x_fifo_size.)
All other cores can not, which results in these two fields containing
zero. We also have platforms that do not provide a value in
priv->plat->[tr]x_fifo_size, resulting in these also being zero.
This causes the new tests introduced by the reverted commit to fail,
and produce e.g.:
stmmaceth f0804000.eth: Can't specify Rx FIFO size
An example of such a platform which fails is QEMU's npcm750-evb.
This uses dwmac1000 which, as noted above, does not have the capability
to provide the FIFO sizes from hardware.
Therefore, revert the commit to maintain compatibility with the way
the driver used to work.

I feel like we don't do a good enough keeping authors of driver
APIs around. The ethtool code base was very nicely compartmentalized
by Michal. Establish a precedent of creating MAINTAINERS entries
for "sections" of the ethtool API. Use Andrew and cable test as
a sample entry. The entry should ideally cover 3 elements:
a core file, test(s), and keywords. The last one is important
because we intend the entries to cover core code *and* reviews
of drivers implementing given API!

Michal did an amazing job converting ethtool to Netlink, but never
added an entry to MAINTAINERS for himself. Create a formal entry
so that we can delegate (portions) of this code to folks.
Over the last 3 years majority of the reviews have been done by
Andrew and I. I suppose Michal didn't want to be on the receiving
end of the flood of patches.

Commit 3ba11e684d16 ("pinctrl: pinconf-generic: print hex value")
unconditionally switched to printing hex values in
pinconf_generic_dump_one(). However, if a dump format is registered for the
dumped pin, the hex value is printed as well. This hex value does not
necessarily correspond 1:1 with the hardware register value (as noted by
commit 3ba11e684d16 ("pinctrl: pinconf-generic: print hex value")). As a
result, user-facing output may include information like:
output drive strength (0x100 uA).
To address this, check if a dump format is registered for the dumped
property, and print the unsigned value instead when applicable.

rxrpc: Call state fixes
Here some call state fixes for AF_RXRPC.
(1) Fix the state of a call to not treat the challenge-response cycle as
part of an incoming call's state set. The problem is that it makes
handling received of the final packet in the receive phase difficult
as that wants to change the call state - but security negotiations may
not yet be complete.
(2) Fix a race between the changing of the call state at the end of the
request reception phase of a service call, recvmsg() collecting the last
data and sendmsg() trying to send the reply before the I/O thread has
advanced the call state.

There's a race in between the rxrpc I/O thread recording the end of the
receive phase of a call and recvmsg() examining the state of the call to
determine whether it has completed.
The problem is that call->_state records the I/O thread's view of the call,
not the application's view (which may lag), so that alone is not
sufficient. To this end, the application also checks whether there is
anything left in call->recvmsg_queue for it to pick up. The call must be
in state RXRPC_CALL_COMPLETE and the recvmsg_queue empty for the call to be
considered fully complete.
In rxrpc_input_queue_data(), the latest skbuff is added to the queue and
then, if it was marked as LAST_PACKET, the state is advanced... But this
is two separate operations with no locking around them.
As a consequence, the lack of locking means that sendmsg() can jump into
the gap on a service call and attempt to send the reply - but then get
rejected because the I/O thread hasn't advanced the state yet.
Simply flipping the order in which things are done isn't an option as that
impacts the client side, causing the checks in rxrpc_kernel_check_life() as
to whether the call is still alive to race instead.
Fix this by moving the update of call->_state inside the skb queue
spinlocked section where the packet is queued on the I/O thread side.
rxrpc's recvmsg() will then automatically sync against this because it has
to take the call->recvmsg_queue spinlock in order to dequeue the last
packet.
rxrpc's sendmsg() doesn't need amending as the app shouldn't be calling it
to send a reply until recvmsg() indicates it has returned all of the
request.

The RXRPC_CALL_SERVER_SECURING state doesn't really belong with the other
states in the call's state set as the other states govern the call's Rx/Tx
phase transition and govern when packets can and can't be received or
transmitted. The "Securing" state doesn't actually govern the reception of
packets and would need to be split depending on whether or not we've
received the last packet yet (to mirror RECV_REQUEST/ACK_REQUEST).
The "Securing" state is more about whether or not we can start forwarding
packets to the application as recvmsg will need to decode them and the
decoding can't take place until the challenge/response exchange has
completed.
Fix this by removing the RXRPC_CALL_SERVER_SECURING state from the state
set and, instead, using a flag, RXRPC_CALL_CONN_CHALLENGING, to track
whether or not we can queue the call for reception by recvmsg() or notify
the kernel app that data is ready. In the event that we've already
received all the packets, the connection event handler will poke the app
layer in the appropriate manner.
Also there's a race whereby the app layer sees the last packet before rxrpc
has managed to end the rx phase and change the state to one amenable to
allowing a reply. Fix this by queuing the packet after calling
rxrpc_end_rx_phase().
