rxrpc: Fix call timer start racing with call destruction
The rxrpc_call struct has a timer used to handle various timed events
relating to a call. This timer can get started from the packet input
routines that are run in softirq mode with just the RCU read lock held.
Unfortunately, because only the RCU read lock is held - and neither ref or
other lock is taken - the call can start getting destroyed at the same time
a packet comes in addressed to that call. This causes the timer - which
was already stopped - to get restarted. Later, the timer dispatch code may
then oops if the timer got deallocated first.
Fix this by trying to take a ref on the rxrpc_call struct and, if
successful, passing that ref along to the timer. If the timer was already
running, the ref is discarded.
The timer completion routine can then pass the ref along to the call's work
item when it queues it. If the timer or work item where already
queued/running, the extra ref is discarded.

====================
wireguard patches for 5.18-rc1
Here's a small set of fixes for the next net push:
1) Pipacs reported a CFI violation in a cleanup routine, which he
triggered using grsec's RAP. I haven't seen reports of this yet from
the Android/CFI world yet, but it's only a matter of time there.
2) A small rng cleanup to the self test harness to make it initialize
faster on 5.18.
3) Wang reported and fixed a skb leak for CONFIG_IPV6=n.
4) After Wang's fix for the direct leak, I investigated how that code
path even could be hit, and found that the netlink layer still
handles IPv6 endpoints, when it probably shouldn't.

The previous commit fixed a memory leak on the send path in the event
that IPv6 is disabled at compile time, but how did a packet even arrive
there to begin with? It turns out we have previously allowed IPv6
endpoints even when IPv6 support is disabled at compile time. This is
awkward and inconsistent. Instead, let's just ignore all things IPv6,
the same way we do other malformed endpoints, in the case where IPv6 is
disabled.

Pull clk updates from Stephen Boyd:
"There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each
time the rate is changed. Previously we wouldn't let clk providers see
a rate that was different if it was still within the range, which
could be bad for power if the clk could run slower when a range
expands. Now the clk provider can decide to do something differently
when the constraints change. This broke Nvidia's clk driver so we had
to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk
framework that we're going to extend in the next release. It already
made it easy to find corner cases in the rate range patches so I'm
excited to see it cover more clk code and increase our confidence in
core framework patches in the future. I also added a kunit test for
the basic clk gate code and that work will continue to cover more
basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and
additions. Qualcomm again dominates the diffstat here with lots more
SoCs being supported and i.MX follows afer that with a similar number
of SoCs gaining clk drivers. Beyond those large additions there's
drivers being modernized to use clk_parent_data so we can move away
from global string names for all the clks in an SoC. Finally there's
lots of little fixes all over the clk drivers for typos, warnings, and
missing clks that aren't critical and get batched up waiting for the
next merge window to open. Nothing super big stands out in the driver
pile. Full details are below.

fs: fix fd table size alignment properly
Jason Donenfeld reports that my commit
1c24a186398f ("fs: fd tables have
to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
embarrassing brown-paper-bag bug.
Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
reason they might not be aligned is because the incoming 'max_fd'
argument might not be aligned.
But aligining the argument - while simple - will cause a "infinitely
big" maxfd (eg NR_OPEN_MAX) to just overflow to zero. Which most
definitely isn't what we want either.
The obvious fix was always just to do the alignment last, but I had
moved it earlier just to make the patch smaller and the code look
simpler. Duh. It certainly made _me_ look simple.

fs: fd tables have to be multiples of BITS_PER_LONG
This has always been the rule: fdtables have several bitmaps in them,
and as a result they have to be sized properly for bitmaps. We walk
those bitmaps in chunks of 'unsigned long' in serveral cases, but even
when we don't, we use the regular kernel bitops that are defined to work
on arrays of 'unsigned long', not on some byte array.
Now, the distinction between arrays of bytes and 'unsigned long'
normally only really ends up being noticeable on big-endian systems, but
Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps()
could be called with an argument that wasn't even a multiple of
BITS_PER_BYTE. And then it fails to do the proper copy even on
little-endian machines.
The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which
didn't actually sanitize the fdtable size sufficiently, and never made
sure it had the proper BITS_PER_LONG alignment.
That's partly because the alignment historically came not from having to
explicitly align things, but simply from previous fdtable sizes, and
from count_open_files(), which counts the file descriptors by walking
them one 'unsigned long' word at a time and thus naturally ends up doing
sizing in the proper 'chunks of unsigned long'.
But with the introduction of close_range(), we now have an external
source of "this is how many files we want to have", and so
sane_fdtable_size() needs to do a better job.
This also adds that explicit alignment to alloc_fdtable(), although
there it is mainly just for documentation at a source code level. The
arithmetic we do there to pick a reasonable fdtable size already aligns
the result sufficiently.
In fact,clang notices that the added ALIGN() in that function doesn't
actually do anything, and does not generate any extra code for it.
It turns out that gcc ends up confusing itself by combining a previous
constant-sized shift operation with the variable-sized shift operations
in roundup_pow_of_two(). And probably due to that doesn't notice that
the ALIGN() is a no-op. But that's a (tiny) gcc misfeature that doesn't
matter. Having the explicit alignment makes sense, and would actually
matter on a 128-bit architecture if we ever go there.
This also adds big comments above both functions about how fdtable sizes
have to have that BITS_PER_LONG alignment.

parisc: Fix patch code locking and flushing
This change fixes the following:
1) The flags variable is not initialized. Always use raw_spin_lock_irqsave
and raw_spin_unlock_irqrestore to serialize patching.
2) flush_kernel_vmap_range is primarily intended for DMA flushes. Since
__patch_text_multiple is often called with interrupts disabled, it is
better to directly call flush_kernel_dcache_range_asm and
flush_kernel_icache_range_asm. This avoids an extra call.
3) The final call to flush_icache_range is unnecessary.
