We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

corrupt
- Change xfs_finobt_count_blocks() to count "free inode btree" blocks
rather than "inode btree" blocks
- Don't report the number of trimmed bytes via FITRIM because the
underlying storage isn't required to do anything and failed discard
IOs aren't reported to the caller anyway

There is a fairly large number of bug fixes for Qualcomm platforms,
most of them addressing issues with the devicetree files for the
newly added Snapdragon X1 based laptops to make them more reliable.
The Qualcomm driver changes address a few build-time issues as well
as runtime problems in the tzmem and scm firmware, the USB Type-C
driver, and the cmd-db and pmic_glink soc drivers.
The NXP i.MX usually gets a bunch of devicetree fixes that is proportional
to the number of supported machines. This includes both warning fixes
and correctness for the 64-bit i.MX9, i.MX8 and layerscape platforms,
as well as a single fix for a 32-bit i.MX6 based board.
The other changes are the usual minor changes, including an update to the
MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs (risc-v).

- A fix for a regression that happened in 6.11 merge window, where the
copying of iovecs for compat mode applications got broken for certain
cases.
- Fix for a bug introduced in 6.10, where if using recv/send bundles
with classic provided buffers, the recv/send would fail to set the
right iovec count. This caused 0 byte send/recv results. Found via
code coverage testing and writing a test case to exercise it.

Node names should be generic.

Merge tag 'iommu-fixes-v6.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux
Pull iommu fixes from Joerg Roedel:
- Fix a device-stall problem in bad io-page-fault setups (faults
received from devices with no supporting domain attached).
- Context flush fix for Intel VT-d.
- Do not allow non-read+non-write mapping through iommufd as most
implementations can not handle that.
- Fix a possible infinite-loop issue in map_pages() path.
- Add Jean-Philippe as reviewer for SMMUv3 SVA support

MAINTAINERS: Add Jean-Philippe as SMMUv3 SVA reviewer
iommu: Do not return 0 from map_pages if it doesn't do anything
iommufd: Do not allow creating areas without READ or WRITE
iommu/vt-d: Fix incorrect domain ID in context flush helper
iommu: Handle iommu faults for a bad iopf setup
io_provided_buffers_select() returns 0 to indicate success, but it should
be returning 1 to indicate that 1 vec was mapped. This causes peeking
to fail with classic provided buffers, and while that's not a use case
that anyone should use, it should still work correctly.
The end result is that no buffer will be selected, and hence a completion
with '0' as the result will be posted, without a buffer attached.

It is not safe to dereference fl->c.flc_owner without first confirming
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()
tests fl_lmops but largely ignores the result and assumes that flc_owner
is an nfs4_delegation anyway. This is wrong.
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave
as it did before the change mentioned below. This is the same as the
current code, but without any reference to a possible delegation.

For buffer registration (or updates), a userspace iovec is copied in
and updated. If the application is within a compat syscall, then the
iovec type is compat_iovec rather than iovec. However, the type used
in __io_sqe_buffers_update() and io_sqe_buffers_register() is always
struct iovec, and hence the source is incremented by the size of a
non-compat iovec in the loop. This misses every other iovec in the
source, and will run into garbage half way through the copies and
return -EFAULT to the application.
Maintain the source address separately and assign to our user vec
pointer, so that copies always happen from the right source address.
While in there, correct a bad placement of __user which triggered
the following sparse warning prior to this fix:
io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression
io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces)
io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec
io_uring/rsrc.c:981:30: got struct iovec *[noderef] __user
