Initial support for the RPC_AUTH_TLS authentication flavor enables
NFSD to eventually accept an RPC_AUTH_TLS probe from clients. This
patch simply prevents NFSD from rejecting these probes completely.
In the meantime, graft this support in now so that RPC_AUTH_TLS
support keeps up with generic code and API changes in the RPC
server.
Down the road, server-side transport implementations will populate
xpo_start_tls when they can support RPC-with-TLS. For example, TCP
will eventually populate it, but RDMA won't.

We have never been able to track down and address the underlying
cause of the performance issues with workqueue-based service
support. svo_enqueue_xprt is called multiple times per RPC, so
it adds instruction path length, but always ends up at the same
function: svc_xprt_do_enqueue(). We do not anticipate needing
this flexibility for dynamic nfsd thread management support.
As a micro-optimization, remove .svo_enqueue_xprt because
Spectre/Meltdown makes virtual function calls more costly.
This change essentially reverts commit b9e13cdfac ("nfsd/sunrpc:

A helper macro was added to make reading socket addresses easier in trace

The boot up check that makes sure that trace events do not reference
pointers to memory that can later be freed when the trace event is read,
incorrectly flagged this as a delayed reference. Update the check to
handle "__get_sockaddr" and not report an error on it.

These are safer because, when used properly, the size of the

to be the same as the source address that is being copied into it.

Because the OUTPUT variable ends with a slash but CURDIR doesn't, to keep
the _OUTPUT value consistent, we add a trailing slash to CURDIR when

Since the _OUTPUT variable holds a value ending with a trailing slash,
there is no need to add another one when defining BOOTSTRAP_OUTPUT and
LIBBPF_OUTPUT variables. Likewise, when defining LIBBPF_INCLUDE and
LIBBPF_BOOTSTRAP_INCLUDE, we shouldn't add an extra slash either for the
same reason.
When building libbpf, the value of the DESTDIR argument should also not

Taking spinlocks from IRQ context is generally problematic for
PREEMPT_RT. That is, in part, why we take trylocks instead. However, a
spin_try_lock() is also problematic since another spin_lock() invocation
can potentially PI-boost the wrong task, as the spin_try_lock() is
invoked from an IRQ-context, so the task on CPU (random task or idle) is
not the actual owner.
Additionally, by deferring the crng pre-init loading to the worker, we
can use the cryptographic hash function rather than xor, which is
perhaps a meaningful difference when considering this data has only been
through the relatively weak fast_mix() function.
The biggest downside of this approach is that the pre-init loading is
now deferred until later, which means things that need random numbers
after interrupts are enabled, but before workqueues are running -- or
before this particular worker manages to run -- are going to get into
trouble. Hopefully in the real world, this window is rather small,
especially since this code won't run until 64 interrupts had occurred.

random_get_entropy() returns a cycles_t, not an unsigned long, which is

Conversely, jiffies is always unsigned long. This commit fixes things to
use cycles_t for fields that use random_get_entropy(), named "cycles",
and unsigned long for fields that use jiffies, named "now". It's also
good to mix in a cycles_t and a jiffies in the same way for both
add_device_randomness and add_timer_randomness, rather than using xor in
one case. Finally, we unify the order of these volatile reads, always
reading the more precise cycles counter, and then jiffies, so that the
cycle counter is as close to the event as possible.

("drm/i915: Add state verification for the TypeC port mode")
added a verification to the TypeC AUX power well enable()/disable()
hooks to check if the TypeC port related to this power well is properly
locked. If the disabling happens asynchronously the verification is
skipped, since in this case the port is unlocked. The detection of
asnychronous disabling doesn't work as intended though, since the power
well's reference count is always 0 when its disable() hook is called
(and since there won't be any domain reference held for this power well
either, the verification is always skipped); remove the verification
from the disable() hook for now. In the power well's enable() hook the
power well's reference will be always >0 and there won't be any
asynchronous disabling pending for it, so we can drop the async refcount
check from there.

Fix a race in the xsk socket teardown code that can lead to a NULL pointer

setting xs->state to XSK_UNBOUND, sets xs->dev to NULL and then waits for any
NAPI processing to terminate using synchronize_net(). After that, the release

There are two problems with the current code. First, setting xs->dev to NULL
before waiting for all users to stop using the socket is not correct. The
entry to the data plane functions xsk_poll(), xsk_sendmsg(), and xsk_recvmsg()
are all guarded by a test that xs->state is in the state XSK_BOUND and if not,
it returns right away. But one process might have passed this test but still
have not gotten to the point in which it uses xs->dev in the code. In this
interim, a second process executing xsk_unbind_dev() might have set xs->dev to
NULL which will lead to a crash for the first process. The solution here is
just to get rid of this NULL assignment since it is not used anymore. Before
commit 42fddcc7c6 ("xsk: use state member for socket synchronization"),
xs->dev was the gatekeeper to admit processes into the data plane functions,
but it was replaced with the state variable xs->state in the aforementioned
commit.
The second problem is that synchronize_net() does not wait for any process in
xsk_poll(), xsk_sendmsg(), or xsk_recvmsg() to complete, which means that the
state they rely on might be cleaned up prematurely. This can happen when the
notifier gets called (at driver unload for example) as it uses xsk_unbind_dev().
Solve this by extending the RCU critical region from just the ndo_xsk_wakeup
to the whole functions mentioned above, so that both the test of xs->state ==
XSK_BOUND and the last use of any member of xs is covered by the RCU critical
section. This will guarantee that when synchronize_net() completes, there will
be no processes left executing xsk_poll(), xsk_sendmsg(), or xsk_recvmsg() and
state can be cleaned up safely. Note that we need to drop the RCU lock for the
skb xmit path as it uses functions that might sleep. Due to this, we have to
retest the xs->state after we grab the mutex that protects the skb xmit code
from, among a number of things, an xsk_unbind_dev() being executed from the
notifier at the same time.

Based on the for-5.18/dt-bindings changes, this adds various new
features on Tegra234 such as IOMMU, audio, gpio-keys, I2C and PWM
support.
Device trees for 64-bit Tegra boards are now also built with overlay
support enabled, which allows firmware to apply overlays and customize
the DTB that is passed to the kernel.
There are also a couple of cleanups and additions for older devices,
such as USB device mode support on Jetson Xavier NX.
