If a PCI device has an associated device_node with power supplies,
pci_bus_add_device() creates platform devices for use by pwrctrl. When the
PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to
locate the related platform device, then unregisters it.
But when we remove a PCI device with no associated device node,
dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the
first device with "dev->of_node == NULL". The result is that we (a)
mistakenly unregister a completely unrelated platform device, leading to
issues like the first trace below, and (b) dereference the NULL pointer
from dev_of_node() when clearing OF_POPULATED, as in the second trace.
Unregister a platform device only if there is one associated with this PCI
device. This resolves issues seen when doing:
# echo 1 > /sys/bus/pci/devices/.../remove
Sample issue from unregistering the wrong platform device:

In the error handling for this function, d is freed without ever
removing it from intc_list which would lead to a use after free.

cpu_max_bits_warn() generates a runtime warning similar as below when
showing /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit)
instead of NR_CPUS to iterate CPUs.

Pull char/misc/IIO/whatever driver subsystem updates from Greg KH:
"Here is the 'big and hairy' char/misc/iio and other small driver
subsystem updates for 6.13-rc1.
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc
drivers actually possible.
I think this is the tipping point, expect to see way more rust
drivers going forward now that these bindings are present. Next
merge window hopefully we will have pci and platform drivers
working, which will fully enable almost all driver subsystems to
start accepting (or at least getting) rust drivers.
This is the end result of a lot of work from a lot of people,
congrats to all of them for getting this far, you've proved many of
us wrong in the best way possible, working code :)
- IIO driver updates, too many to list individually, that subsystem
keeps growing and growing...
- Interconnect driver updates
- nvmem driver updates
- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH:
"Here is the big set of staging driver changes for 6.13-rc1.
Lots of changes this merge cycle, drivers removed and drivers added.
Highlights include:
- removals of the following staging drivers due to no forward
progress and no one having either the hardware or the time/energy
to deal with them anymore:
- fieldbus
- gdm724x
- olpc_dcon
- rtl8712
- rts5208
- vt6655
- vt6656
If anyone has this hardware and wants to work on the drivers, it
can be an easy revert to get them back.
- addition of the gpib driver subsystem. Lots of drivers for really
old and semi-old interfaces to lab equipments. We expect lots of
churn in these drivers as they get cleaned up to "working" order.
These were added at the request of a user and the maintainer/author
of them is helping out with the effort

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.13-rc1.
Overall, a pretty slow development cycle, the majority of the work
going into the debugfs interface for the thunderbolt (i.e. USB4) code,
to help with debugging the myrad ways that hardware vendors get their
interfaces messed up. Other than that, here's the highlights:
- thunderbolt changes and additions to debugfs interfaces
- lots of device tree updates for new and old hardware
- UVC configfs gadget updates and new apis for features
- xhci driver updates and fixes
- dwc3 driver updates and fixes
- typec driver updates and fixes

syzbot triggered the following WARN_ON:
WARNING: CPU: 0 PID: 16 at io_uring/tctx.c:51 __io_uring_free+0xfa/0x140 io_uring/tctx.c:51
which is the
WARN_ON_ONCE(!xa_empty(&tctx->xa));
sanity check in __io_uring_free() when a io_uring_task is going through
its final put. The syzbot test case includes injecting memory allocation
failures, and it very much looks like xa_store() can fail one of its
memory allocations and end up with ->head being non-NULL even though no
entries exist in the xarray.
Until this issue gets sorted out, work around it by attempting to
iterate entries in our xarray, and WARN_ON_ONCE() if one is found.

This reverts commit ff123eb7741638d55abf82fac090bb3a543c1e74.
Allowing large pages for KASAN shadow mappings isn't inherently wrong,
but adding POPULATE_KASAN_MAP_SHADOW to large_allowed() exposes an issue
in can_large_pud() and can_large_pmd().
Since commit d8073dc6bc04 ("s390/mm: Allow large pages only for aligned
physical addresses"), both can_large_pud() and can_large_pmd() call _pa()
to check if large page physical addresses are aligned. However, _pa()
has a side effect: it allocates memory in POPULATE_KASAN_MAP_SHADOW
mode. This results in massive memory leaks.
The proper fix would be to address both large_allowed() and _pa()'s side
effects, but for now, revert this change to avoid the leaks.

A sigqueue belonging to a posix timer, which target is not a specific
thread but a whole thread group, is preferrably targeted to the current
task if it is part of that thread group.
However nothing prevents a posix timer event from queueing such a
sigqueue from a reaped yet running task. The interruptible code space
between exit_notify() and the final call to schedule() is enough for
posix_timer_fn() hrtimer to fire.
If that happens while the current task is part of the thread group
target, it is proposed to handle it but since its sighand pointer may
have been cleared already, the sigqueue is dropped even if there are
other tasks running within the group that could handle it.
As a result posix timers with thread group wide target may miss signals
when some of their threads are exiting.
Fix this with verifying that the current task hasn't been through
exit_notify() before proposing it as a preferred target so as to ensure
that its sighand is still here and stable.
complete_signal() might still reconsider the choice and find a better
target within the group if current has passed retarget_shared_pending()
already.

Pull more tracing updates from Steven Rostedt:
- Add trace flag for NEED_RESCHED_LAZY
Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of
the common_flags. This will now show when the NEED_RESCHED_LAZY flag
is set that is used for debugging latency issues in the kernel via a
trace.
- Remove leftover "__idx" variable when SRCU was removed from the
tracepoint code
- Add rcu_tasks_trace guard
To add a guard() around the tracepoint code, a rcu_tasks_trace guard
needs to be created first.
- Remove __DO_TRACE() macro and just call __DO_TRACE_CALL() directly
The DO_TRACE() macro has conditional locking depending on what was
passed into the macro parameters. As the guts of the macro has been
moved to __DO_TRACE_CALL() to handle static call logic, there's no
reason to keep the __DO_TRACE() macro around.
It is better to just do the locking in place without the conditionals
and call __DO_TRACE_CALL() from those locations. The "cond" passed in
can also be moved out of that macro. This simplifies the code.
- Remove the "cond" from the system call tracepoint macros
The "cond" variable was added to allow some tracepoints to check a
condition within the static_branch (jump/nop) logic. The system calls
do not need this. Removing it simplifies the code.
- Replace scoped_guard() with just guard() in the tracepoint logic
guard() works just as well as scoped_guard() in the tracepoint logic
and the scoped_guard() causes some issues.

This allows killing processes that wait for a lock when one process is
stuck waiting for the NFS server. This aims to complete the coverage
of NFS operations being killable, like nfs_direct_wait() does, for
example.

Every pNFS SCSI IO wants to do LAYOUTGET, then within the layout find the
device which can drive GETDEVINFO, then finally may need to prep the device
with a reservation. This slow work makes a mess of IO latencies if one of
the later steps is going to fail for awhile.
If we're unable to register a SCSI device, ensure we mark the device as
unavailable so that it will timeout and be re-added via GETDEVINFO. This
avoids repeated doomed attempts to register a device in the IO path.
Add some clarifying comments as well.

Since commit d869da91cccb ("nfs/blocklayout: Fix premature PR key
unregistration") an unmount of a pNFS SCSI layout-enabled NFS may
dereference a NULL block_device in:
bl_unregister_scsi+0x16/0xe0 [blocklayoutdriver]
bl_free_device+0x70/0x80 [blocklayoutdriver]
bl_free_deviceid_node+0x12/0x30 [blocklayoutdriver]

task_work_run+0x59/0x90
syscall_exit_to_user_mode+0x217/0x220
do_syscall_64+0x8e/0x160
This happens because even though we were able to create the
nfs4_deviceid_node, the lookup for the device was unable to attach the
block device to the pnfs_block_dev.
If we never found a block device to register, we can avoid this case with
the PNFS_BDEV_REGISTERED flag. Move the deref behind the test for the
flag.

Reproduction script:

mkdir -p /mnt/nfs/netns_1

mount /dev/sdb /mnt/nfsshare
systemctl restart nfs-server
chmod 777 /mnt/nfsshare
exportfs -i -o rw,no_root_squash *:/mnt/nfsshare
ip netns add netns_1
ip link add name veth_1_peer type veth peer veth_1
ifconfig veth_1_peer 11.11.0.254 up
ip link set veth_1 netns netns_1
ip netns exec netns_1 ifconfig veth_1 11.11.0.1
ip netns exec netns_1 /root/iptables -A OUTPUT -d 11.11.0.254 -p tcp \
--tcp-flags FIN FIN -j DROP
(note: In my environment, a DESTROY_CLIENTID operation is always sent
immediately, breaking the nfs tcp connection.)
ip netns exec netns_1 timeout -s 9 300 mount -t nfs -o proto=tcp,vers=4.1 \
11.11.0.254:/mnt/nfsshare /mnt/nfs/netns_1
ip netns del netns_1
The reason here is that the tcp socket in netns_1 (nfs side) has been
shutdown and closed (done in xs_destroy), but the FIN message (with ack)
is discarded, and the nfsd side keeps sending retransmission messages.
As a result, when the tcp sock in netns_1 processes the received message,
it sends the message (FIN message) in the sending queue, and the tcp timer
is re-established. When the network namespace is deleted, the net structure
accessed by tcp's timer handler function causes problems.
To fix this problem, let's hold netns refcnt for the tcp kernel socket as
done in other modules. This is an ugly hack which can easily be backported
to earlier kernels. A proper fix which cleans up the interfaces will
follow, but may not be so easy to backport.

We've noticed a situation where an unstable TCP connection can cause the
TLS handshake to timeout waiting for userspace to complete it. When this
happens, we don't want to return from xs_tls_handshake_sync() with zero, as
this will cause the upper xprt to be set CONNECTED, and subsequent attempts
to transmit will be returned with -EPIPE. The sunrpc machine does not
recover from this situation and will spin attempting to transmit.
The return value of tls_handshake_cancel() can be used to detect a race
with completion:
* tls_handshake_cancel - cancel a pending handshake
* Return values:
* %true - Uncompleted handshake request was canceled
* %false - Handshake request already completed or not found
If true, we do not want the upper xprt to be connected, so return
-ETIMEDOUT. If false, its possible the handshake request was lost and
that may be the reason for our timeout. Again we do not want the upper
xprt to be connected, so return -ETIMEDOUT.
Ensure that we alway return an error from xs_tls_handshake_sync() if we
call tls_handshake_cancel().

When exporting only one file system with fsid=0 on the server side, the
client alternately uses the ro/rw mount options to perform the mount
operation, and a new vfsmount is generated each time.
It can be reproduced as follows:
[root@localhost ~]# mount /dev/sda /mnt2
[root@localhost ~]# echo "/mnt2 *(rw,no_root_squash,fsid=0)" >/etc/exports
[root@localhost ~]# systemctl restart nfs-server
[root@localhost ~]# mount -t nfs -o ro,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount -t nfs -o rw,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount -t nfs -o ro,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount -t nfs -o rw,vers=4 127.0.0.1:/ /mnt/sdaa
[root@localhost ~]# mount | grep nfs4
127.0.0.1:/ on /mnt/sdaa type nfs4 (ro,relatime,vers=4.2,rsize=1048576,...
127.0.0.1:/ on /mnt/sdaa type nfs4 (rw,relatime,vers=4.2,rsize=1048576,...
127.0.0.1:/ on /mnt/sdaa type nfs4 (ro,relatime,vers=4.2,rsize=1048576,...
127.0.0.1:/ on /mnt/sdaa type nfs4 (rw,relatime,vers=4.2,rsize=1048576,...
[root@localhost ~]#
We expected that after mounting with the ro option, using the rw option to
mount again would return EBUSY, but the actual situation was not the case.
As shown above, when mounting for the first time, a superblock with the ro
flag will be generated, and at the same time, in do_new_mount_fc -->
do_add_mount, it detects that the superblock corresponding to the current
target directory is inconsistent with the currently generated one
(path->mnt->mnt_sb != newmnt->mnt.mnt_sb), and a new vfsmount will be
generated.
When mounting with the rw option for the second time, since no matching
superblock can be found in the fs_supers list, a new superblock with the
rw flag will be generated again. The superblock in use (ro) is different
from the newly generated superblock (rw), and a new vfsmount will be
generated again.
When mounting with the ro option for the third time, the superblock (ro)
is found in fs_supers, the superblock in use (rw) is different from the
found superblock (ro), and a new vfsmount will be generated again.
We can switch between ro/rw through remount, and only one superblock needs
to be generated, thus avoiding the problem of repeated generation of
vfsmount caused by switching superblocks.
Furthermore, This can also resolve the issue described in the link.
