Some trivial syzbot fixes, two more serious btree fixes found by looping
single_devices.ktest small_nodes:
- Topology error on split after merge, where we accidentaly picked the
node being deleted for the pivot, resulting in an assertion pop
- New nodes being preallocated were left on the freedlist, unlocked,
resulting in them sometimes being accidentally freed: this dated from
pre-cycle detector, when we could leave them locked. This should have
resulted in more explosions and fireworks, but turned out to be
surprisingly hard to hit because the preallocated nodes were being
used right away.
the fix for this is bigger than we'd like - reworking btree list
handling was a bit invasive - but we've now got more assertions and
it's well tested.
- Also another mishandled transaction restart fix (in
btree_node_prefetch) - we're almost done with those.

"Here is a (hopefully) final round of arm64 fixes for 6.12 that address
some user-visible floating point register corruption. Both of the
Marks have been working on this for a couple of weeks and we've ended
up in a position where SVE is solid but SME still has enough pending
issues that the most pragmatic solution for the release and stable
backports is to disable the feature. Yes, it's a shame, but the
hardware is rare as hen's teeth at the moment and we're better off
getting back to a known good state before fixing it all properly.
We're also improving the selftests for 6.13 to help avoid merging
broken code in the future.
Anyway, the good news is that we're removing a lot more code than
we're adding.

- Fix handling of SVE traps from userspace on preemptible kernels

Change OPT_STR max value to be 1 less than the "ARRAY_SIZE" of "_choices"
array. As a result, remove -1 from (opt->max-1) in bch2_opt_to_text.
The "_choices" array is a null-terminated array, so computing the maximum
using "ARRAY_SIZE" without subtracting 1 yields an incorrect result. Since
bch2_opt_validate don't subtract 1, as bch2_opt_to_text does, values
bigger than the actual maximum would pass through option validation.

When allocating new btree nodes, we were leaving them on the freeable
list - unlocked - allowing them to be reclaimed: ouch.
Additionally, bch2_btree_node_free_never_used() ->
bch2_btree_node_hash_remove was putting it on the freelist, while
bch2_btree_node_free_never_used() was putting it back on the btree
update reserve list - ouch.
Originally, the code was written to always keep btree nodes on a list -
live or freeable - and this worked when new nodes were kept locked.
But now with the cycle detector, we can't keep nodes locked that aren't
tracked by the cycle detector; and this is fine as long as they're not
reachable.
We also have better and more robust leak detection now, with memory
allocation profiling, so the original justification no longer applies.

The perf_test does not check the number of iterations and threads
when it is zero. If nr_thread is 0, the perf test will keep
waiting for wakekup. If iteration is 0, it will cause exception
of division by zero. This can be reproduced by:
echo "rand_insert 0 1" > /sys/fs/bcachefs/${uuid}/perf_test
or

Syzbot found an assertion pop, by generating an ancient filesystem
version with an invalid bkey_format (with fields that can overflow) as
well as packed keys that aren't representable unpacked.
This breaks key comparisons in all sorts of painful ways.
Filesystems have been automatically rewriting nodes with such invalid
formats for years; we can safely drop support for them.

If a call gets aborted (e.g. because kafs saw a signal) between it being
queued for connection and the I/O thread picking up the call, the abort
will be prioritised over the connection and it will be removed from
local->new_client_calls by rxrpc_disconnect_client_call() without a lock
being held. This may cause other calls on the list to disappear if a race
occurs.
Fix this by taking the client_call_lock when removing a call from whatever

The SMC-R variant of the SMC protocol used direct call to function
ib_device_ops.get_netdev() to lookup netdev. As we used mlx5 device
driver to run SMC-R, it failed to find a device, because in mlx5_ib the
internal net device management for retrieving net devices was replaced
by a common interface ib_device_get_netdev() in commit 8d159eb211
("RDMA/mlx5: Use IB set_netdev and get_netdev functions").
Since such direct accesses to the internal net device management is not
recommended at all, update the SMC-R code to use proper API
ib_device_get_netdev().

The current panthor_device_mmap_io() implementation has two issues:
1. For mapping DRM_PANTHOR_USER_FLUSH_ID_MMIO_OFFSET,
panthor_device_mmap_io() bails if VM_WRITE is set, but does not clear
VM_MAYWRITE. That means userspace can use mprotect() to make the mapping
writable later on. This is a classic Linux driver gotcha.
I don't think this actually has any impact in practice:
When the GPU is powered, writes to the FLUSH_ID seem to be ignored; and
when the GPU is not powered, the dummy_latest_flush page provided by the
driver is deliberately designed to not do any flushes, so the only thing
writing to the dummy_latest_flush could achieve would be to make *more*
flushes happen.
2. panthor_device_mmap_io() does not block MAP_PRIVATE mappings (which are
mappings without the VM_SHARED flag).
MAP_PRIVATE in combination with VM_MAYWRITE indicates that the VMA has
copy-on-write semantics, which for VM_PFNMAP are semi-supported but
fairly cursed.
In particular, in such a mapping, the driver can only install PTEs
during mmap() by calling remap_pfn_range() (because remap_pfn_range()
wants to **store the physical address of the mapped physical memory into
the vm_pgoff of the VMA**); installing PTEs later on with a fault
handler (as panthor does) is not supported in private mappings, and so
if you try to fault in such a mapping, vmf_insert_pfn_prot() splats when
it hits a BUG() check.
Fix it by clearing the VM_MAYWRITE flag (userspace writing to the FLUSH_ID
doesn't make sense) and requiring VM_SHARED (copy-on-write semantics for
the FLUSH_ID don't make sense).
Reproducers for both scenarios are in the notes of my patch on the mailing
list; I tested that these bugs exist on a Rock 5B machine.
Note that I only compile-tested the patch, I haven't tested it; I don't
have a working kernel build setup for the test machine yet. Please test it
before applying it.

Write the size of the optional payload of SOF_IPC4_MOD_INIT_INSTANCE
message to extension param_size-bits.
The previous IPC4 version does not set these bits that should indicate
the size of the optional payload (struct sof_ipc4_probe_cfg). The old
firmware side component code works well without these bits, but when
the probes are converted to use the generic module API, this does not

I noticed that recently, simple operations like "make" started
failing on NFSv3 mounts of ext4 exports. Network capture shows that
READDIRPLUS operated correctly but READDIR failed with
NFS3ERR_INVAL. The vfs_llseek() call returned EINVAL when it is
passed a non-zero starting directory cookie.
I bisected to commit c689bdd3bf ("nfsd: further centralize
protocol version checks.").
Turns out that nfsd3_proc_readdir() does not call fh_verify() before
it calls nfsd_readdir(), so the new fhp->fh_64bit_cookies boolean is
not set properly. This leaves the NFSD_MAY_64BIT_COOKIE unset when
the directory is opened.
For ext4, this causes the wrong "max file size" value to be used
when sanity checking the incoming directory cookie (which is a seek
offset value).
The fhp->fh_64bit_cookies boolean is /always/ properly initialized
after nfsd_open() returns. There doesn't seem to be a reason for the
generic NFSD open helper to handle the f_mode fix-up for
directories, so just move that to the one caller that tries to open
an S_IFDIR with NFSD_MAY_64BIT_COOKIE.
