[PATCH 5.10 01/15] x86/smpboot: Move rcu_cpu_starting() earlier

[Greg Kroah-Hartman]

From: Paul E. McKenney <paulmck@kernel.org>

commit 29368e09392123800e5e2bf0f3eda91f16972e52 upstream.

The call to rcu_cpu_starting() in mtrr_ap_init() is not early enough
in the CPU-hotplug onlining process, which results in lockdep splats
as follows:

=============================
WARNING: suspicious RCU usage
5.9.0+ #268 Not tainted
-----------------------------

other info that might help us debug this:

This is avoided by moving the call to rcu_cpu_starting up near
the beginning of the start_secondary() function.  Note that the
raw_smp_processor_id() is required in order to avoid calling into lockdep
before RCU has declared the CPU to be watched for readers.

[PATCH 5.10 02/15] vfs: fix copy_file_range() regression in cross-fs copies

[Greg Kroah-Hartman]

From: Amir Goldstein <amir73il@gmail.com>

commit 868f9f2f8e004bfe0d3935b1976f625b2924893b upstream.

[backport comments for pre v5.15:
- This commit has a bug fixed by commit 10bc8e4af659 ("vfs: fix
  copy_file_range() averts filesystem freeze protection")
- ksmbd mentions are irrelevant - ksmbd hunks were dropped
]

A regression has been reported by Nicolas Boichat, found while using the
copy_file_range syscall to copy a tracefs file.

Before commit 5dae222a5ff0 ("vfs: allow copy_file_range to copy across
devices") the kernel would return -EXDEV to userspace when trying to
copy a file across different filesystems.  After this commit, the
syscall doesn't fail anymore and instead returns zero (zero bytes
copied), as this file's content is generated on-the-fly and thus reports
a size of zero.

Another regression has been reported by He Zhe - the assertion of
WARN_ON_ONCE(ret == -EOPNOTSUPP) can be triggered from userspace when
copying from a sysfs file whose read operation may return -EOPNOTSUPP.

Since we do not have test coverage for copy_file_range() between any two
types of filesystems, the best way to avoid these sort of issues in the
future is for the kernel to be more picky about filesystems that are
allowed to do copy_file_range().

This patch restores some cross-filesystem copy restrictions that existed
prior to commit 5dae222a5ff0 ("vfs: allow copy_file_range to copy across
devices"), namely, cross-sb copy is not allowed for filesystems that do
not implement ->copy_file_range().

Filesystems that do implement ->copy_file_range() have full control of
the result - if this method returns an error, the error is returned to
the user.  Before this change this was only true for fs that did not
implement the ->remap_file_range() operation (i.e.  nfsv3).

Filesystems that do not implement ->copy_file_range() still fall-back to
the generic_copy_file_range() implementation when the copy is within the
same sb.  This helps the kernel can maintain a more consistent story
about which filesystems support copy_file_range().

nfsd and ksmbd servers are modified to fall-back to the
generic_copy_file_range() implementation in case vfs_copy_file_range()
fails with -EOPNOTSUPP or -EXDEV, which preserves behavior of
server-side-copy.

fall-back to generic_copy_file_range() is not implemented for the smb
operation FSCTL_DUPLICATE_EXTENTS_TO_FILE, which is arguably a correct
change of behavior.

[PATCH 5.10 03/15] vfs: fix copy_file_range() averts filesystem freeze protection

[Greg Kroah-Hartman]

From: Amir Goldstein <amir73il@gmail.com>

commit 10bc8e4af65946b727728d7479c028742321b60a upstream.

[backport comments for pre v5.15:
- ksmbd mentions are irrelevant - ksmbd hunks were dropped
- sb_write_started() is missing - assert was dropped
]

Commit 868f9f2f8e00 ("vfs: fix copy_file_range() regression in cross-fs
copies") removed fallback to generic_copy_file_range() for cross-fs
cases inside vfs_copy_file_range().

To preserve behavior of nfsd and ksmbd server-side-copy, the fallback to
generic_copy_file_range() was added in nfsd and ksmbd code, but that
call is missing sb_start_write(), fsnotify hooks and more.

Ideally, nfsd and ksmbd would pass a flag to vfs_copy_file_range() that
will take care of the fallback, but that code would be subtle and we got
vfs_copy_file_range() logic wrong too many times already.

Instead, add a flag to explicitly request vfs_copy_file_range() to
perform only generic_copy_file_range() and let nfsd and ksmbd use this
flag only in the fallback path.

This choise keeps the logic changes to minimum in the non-nfsd/ksmbd code
paths to reduce the risk of further regressions.

[PATCH 5.10 04/15] nfp: fix use-after-free in area_cache_get()

[Greg Kroah-Hartman]

From: Jialiang Wang <wangjialiang0806@163.com>

commit 02e1a114fdb71e59ee6770294166c30d437bf86a upstream.

area_cache_get() is used to distribute cache->area and set cache->id,
 and if cache->id is not 0 and cache->area->kref refcount is 0, it will
 release the cache->area by nfp_cpp_area_release(). area_cache_get()
 set cache->id before cpp->op->area_init() and nfp_cpp_area_acquire().

But if area_init() or nfp_cpp_area_acquire() fails, the cache->id is
 is already set but the refcount is not increased as expected. At this
 time, calling the nfp_cpp_area_release() will cause use-after-free.

To avoid the use-after-free, set cache->id after area_init() and
 nfp_cpp_area_acquire() complete successfully.

Note: This vulnerability is triggerable by providing emulated device
 equipped with specified configuration.

[PATCH 5.10 05/15] fuse: always revalidate if exclusive create

[Greg Kroah-Hartman]

From: Miklos Szeredi <mszeredi@redhat.com>

commit df8629af293493757beccac2d3168fe5a315636e upstream.

Failure to do so may result in EEXIST even if the file only exists in the
cache and not in the filesystem.

The atomic nature of O_EXCL mandates that the cached state should be
ignored and existence verified anew.

There may be failure when start 1 channel recording after

Microchip USB Analyzer can activate the internal termination resistors
by setting the "termination" option ON, or OFF to to deactivate them.
As I've observed, both with my oscilloscope and captured USB packets
below, you must send "0" to turn it ON, and "1" to turn it OFF.

>From the schematics in the user's guide, I can confirm that you must
drive the CAN_RES signal LOW "0" to activate the resistors.

Reverse the argument value of usb_msg.termination to fix this.

These are the two commands sequence, ON then OFF.

[PATCH 5.10 14/15] ASoC: cs42l51: Correct PGA Volume minimum value

[Greg Kroah-Hartman]

From: Charles Keepax <ckeepax@opensource.cirrus.com>

[ Upstream commit 3d1bb6cc1a654c8693a85b1d262e610196edec8b ]

The table in the datasheet actually shows the volume values in the wrong
order, with the two -3dB values being reversed. This appears to have
caused the lower of the two values to be used in the driver when the
higher should have been, correct this mixup.

[PATCH 5.10 15/15] nvme-pci: clear the prp2 field when not used

[Greg Kroah-Hartman]

From: Lei Rao <lei.rao@intel.com>

[ Upstream commit a56ea6147facce4ac1fc38675455f9733d96232b ]

If the prp2 field is not filled in nvme_setup_prp_simple(), the prp2
field is garbage data. According to nvme spec, the prp2 is reserved if
the data transfer does not cross a memory page boundary, so clear it to
zero if it is not used.
