59f3b13816 sunrpc: merge svc_rqst_alloc() into svc_prepare_thread()
The only caller of svc_rqst_alloc() is svc_prepare_thread().  So merge
the one into the other and simplify.

9dcbc4e070 sunrpc: don't take ->sv_lock when updating ->sv_nrthreads.
As documented in svc_xprt.c, sv_nrthreads is protected by the service
mutex, and it does not need ->sv_lock.
(->sv_lock is needed only for sv_permsocks, sv_tempsocks, and
sv_tmpcnt).

So remove the unnecessary locking.

60749cbe3d sunrpc: change sp_nrthreads from atomic_t to unsigned int.
sp_nrthreads is only ever accessed under the service mutex
  nlmsvc_mutex nfs_callback_mutex nfsd_mutex
so these is no need for it to be an atomic_t.

The fact that all code using it is single-threaded means that we can
simplify svc_pool_victim and remove the temporary elevation of
sp_nrthreads.

ENGINE API has been deprecated since OpenSSL version 3.0 [1].

70fd1966c9 KEYS: prevent NULL pointer dereference in find_asymmetric_key()
In find_asymmetric_key(), if all NULLs are passed in the id_{0,1,2}
arguments, the kernel will first emit WARN but then have an oops
because id_2 gets dereferenced anyway.

Add the missing id_2 check and move WARN_ON() to the final else branch
to avoid duplicate NULL checks.

061a785a11 ntb: Force physically contiguous allocation of rx ring buffers
Physical addresses under IOVA on x86 platform are mapped contiguously
as a side effect before the patch that removed CONFIG_DMA_REMAP. The
NTB rx buffer ring is a single chunk DMA buffer that is allocated
against the NTB PCI device. If the receive side is using a DMA device,
then the buffers are remapped against the DMA device before being
submitted via the dmaengine API. This scheme becomes a problem when
the physical memory is discontiguous. When dma_map_page() is called
on the kernel virtual address from the dma_alloc_coherent() call, the
new IOVA mapping no longer points to all the physical memory allocated
due to being discontiguous. Change dma_alloc_coherent() to dma_alloc_attrs()
in order to force DMA_ATTR_FORCE_CONTIGUOUS attribute. This is the best
fix for the circumstance. A potential future solution may be having the DMA
mapping API providing a way to alias an existing IOVA mapping to a new
device perhaps.

This fix is not to fix the patch pointed to by the fixes tag, but to fix
the issue arised in the ntb_transport driver on x86 platforms after the
said patch is applied.

e51aded92d ntb: ntb_hw_switchtec: Fix use after free vulnerability in switchtec_ntb_remove due to race condition
In the switchtec_ntb_add function, it can call switchtec_ntb_init_sndev
function, then &sndev->check_link_status_work is bound with
check_link_status_work. switchtec_ntb_link_notification may be called
to start the work.

If we remove the module which will call switchtec_ntb_remove to make
cleanup, it will free sndev through kfree(sndev), while the work
mentioned above will be used. The sequence of operations that may lead
to a UAF bug is as follows:

CPU0                                 CPU1

                        | check_link_status_work
switchtec_ntb_remove    |
kfree(sndev);           |
                        | if (sndev->link_force_down)
                        | // use sndev

Fix it by ensuring that the work is canceled before proceeding with
the cleanup in switchtec_ntb_remove.

crash: Fix riscv64 crash memory reserve dead loop
On RISCV64 Qemu machine with 512MB memory, cmdline "crashkernel=500M,high"
will cause system stall as below:

	 Zone ranges:
	   DMA32    [mem 0x0000000080000000-0x000000009fffffff]
	   Normal   empty
	 Movable zone start for each node
	 Early memory node ranges
	   node   0: [mem 0x0000000080000000-0x000000008005ffff]
	   node   0: [mem 0x0000000080060000-0x000000009fffffff]
	 Initmem setup node 0 [mem 0x0000000080000000-0x000000009fffffff]
	(stall here)

commit 5d99cadf1568 ("crash: fix x86_32 crash memory reserve dead loop
bug") fix this on 32-bit architecture. However, the problem is not
completely solved. If `CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX` on 64-bit
architecture, for example, when system memory is equal to
CRASH_ADDR_LOW_MAX on RISCV64, the following infinite loop will also occur:

	-> reserve_crashkernel_generic() and high is true
	   -> alloc at [CRASH_ADDR_LOW_MAX, CRASH_ADDR_HIGH_MAX] fail
	      -> alloc at [0, CRASH_ADDR_LOW_MAX] fail and repeatedly
	         (because CRASH_ADDR_LOW_MAX = CRASH_ADDR_HIGH_MAX).

As Catalin suggested, do not remove the ",high" reservation fallback to
",low" logic which will change arm64's kdump behavior, but fix it by
skipping the above situation similar to commit d2f32f23190b ("crash: fix
x86_32 crash memory reserve dead loop").

After this patch, it print:
	cannot allocate crashkernel (size:0x1f400000)

eac2ca2d68 io_uring: check if we need to reschedule during overflow flush
In terms of normal application usage, this list will always be empty.
And if an application does overflow a bit, it'll have a few entries.
However, nothing obviously prevents syzbot from running a test case
that generates a ton of overflow entries, and then flushing them can
take quite a while.

Check for needing to reschedule while flushing, and drop our locks and
do so if necessary. There's no state to maintain here as overflows
always prune from head-of-list, hence it's fine to drop and reacquire
the locks at the end of the loop.

eed138d67d io_uring: improve request linking trace
Right now any link trace is listed as being linked after the head
request in the chain, but it's more useful to note explicitly which
request a given new request is chained to. Change the link trace to dump
the tail request so that chains are immediately apparent when looking at
traces.

baeb9a7d8b Enable PREEMPT_RT on supported architectures:
After twenty years of development we finally reached the point to enable
   PREEMPT_RT support in the mainline kernel.
 
   All prerequisites are merged, so enable it on the supported architectures
   ARM64, RISCV and X86(32/64-bit).

8a23c9e1ba selinux,smack: properly reference the LSM blob in security_watch_key()
Unfortunately when we migrated the lifecycle management of the key LSM
blob to the LSM framework we forgot to convert the security_watch_key()
callbacks for SELinux and Smack.  This patch corrects this by making use
of the selinux_key() and smack_key() helper functions respectively.

This patch also removes some input checking in the Smack callback as it
is no longer needed.

Fixes: 5f8d28f6d7 ("lsm: infrastructure management of the key security blob")
