Merge tag 'vfs-6.9.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull misc vfs updates from Christian Brauner:
"Misc features, cleanups, and fixes for vfs and individual filesystems.
Features:
- Support idmapped mounts for hugetlbfs.
- Add RWF_NOAPPEND flag for pwritev2(). This allows us to fix a bug
where the passed offset is ignored if the file is O_APPEND. The new
flag allows a caller to enforce that the offset is honored to
conform to posix even if the file was opened in append mode.
- Move i_mmap_rwsem in struct address_space to avoid false sharing
between i_mmap and i_mmap_rwsem.
- Convert efs, qnx4, and coda to use the new mount api.
- Add a generic is_dot_dotdot() helper that's used by various
filesystems and the VFS code instead of open-coding it multiple
times.
- Recently we've added stable offsets which allows stable ordering
when iterating directories exported through NFS on e.g., tmpfs
filesystems. Originally an xarray was used for the offset map but
that caused slab fragmentation issues over time. This switches the
offset map to the maple tree which has a dense mode that handles
this scenario a lot better. Includes tests.
- Finally merge the case-insensitive improvement series Gabriel has
been working on for a long time. This cleanly propagates case
insensitive operations through ->s_d_op which in turn allows us to
remove the quite ugly generic_set_encrypted_ci_d_ops() operations.
It also improves performance by trying a case-sensitive comparison
first and then fallback to case-insensitive lookup if that fails.
This also fixes a bug where overlayfs would be able to be mounted
over a case insensitive directory which would lead to all sort of
odd behaviors.
Cleanups:
- Make file_dentry() a simple accessor now that ->d_real() is
simplified because of the backing file work we did the last two
cycles.
- Use the dedicated file_mnt_idmap helper in ntfs3.
- Use smp_load_acquire/store_release() in the i_size_read/write
helpers and thus remove the hack to handle i_size reads in the
filemap code.
- The SLAB_MEM_SPREAD is a nop now. Remove it from various places in
fs/
- It's no longer necessary to perform a second built-in initramfs
unpack call because we retain the contents of the previous
extraction. Remove it.
- Now that we have removed various allocators kfree_rcu() always
works with kmem caches and kmalloc(). So simplify various places
that only use an rcu callback in order to handle the kmem cache
case.
- Convert the pipe code to use a lockdep comparison function instead
of open-coding the nesting making lockdep validation easier.
- Move code into fs-writeback.c that was located in a header but can
be made static as it's only used in that one file.
- Rewrite the alignment checking iterators for iovec and bvec to be
easier to read, and also significantly more compact in terms of
generated code. This saves 270 bytes of text on x86-64 (with
clang-18) and 224 bytes on arm64 (with gcc-13). In profiles it also
saves a bit of time for the same workload.
- Switch various places to use KMEM_CACHE instead of
kmem_cache_create().
- Use inode_set_ctime_to_ts() in inode_set_ctime_current()
- Use kzalloc() in name_to_handle_at() to avoid kernel infoleak.
- Various smaller cleanups for eventfds.
Fixes:
- Fix various comments and typos, and unneeded initializations.
- Fix stack allocation hack for clang in the select code.
- Improve dump_mapping() debug code on a best-effort basis.
- Fix build errors in various selftests.
- Avoid wrap-around instrumentation in various places.
- Don't allow user namespaces without an idmapping to be used for
idmapped mounts.
- Fix sysv sb_read() call.
- Fix fallback implementation of the get_name() export operation"

linux_kselftest-kunit-6.9-rc1
This KUnit next update for Linux 6.9-rc1 consists of:
-- fix to make kunit_bus_type const
-- kunit tool change to Print UML command
-- DRM device creation helpers are now using the new kunit device
creation helpers. This change resulted in DRM helpers switching
from using a platform_device, to a dedicated bus and device type
used by kunit. kunit devices don't set DMA mask and this caused
regression on some drm tests as they can't allocate DMA buffers.
Fix this problem by setting DMA masks on the kunit device during
initialization.
-- KUnit has several macros which accept a log message, which can
contain printf format specifiers. Some of these (the explicit
log macros) already use the __printf() gcc attribute to ensure
the format specifiers are valid, but those which could fail the
test, and hence used __kunit_do_failed_assertion() behind the scenes,
did not.
These include: KUNIT_EXPECT_*_MSG(), KUNIT_ASSERT_*_MSG(), and
KUNIT_FAIL()
A 9 patch series adds the __printf() attribute, and fixes all of
the issues uncovered.

Tracing fixes for v6.8-rc7:
- Do not allow large strings (> 4096) as single write to trace_marker The size of a string written into trace_marker was determined by the size of the sub-buffer in the ring buffer. That size is dependent on the PAGE_SIZE of the architecture as it can be mapped into user space. But on PowerPC, where PAGE_SIZE is 64K, that made the limit of the string of writing into trace_marker 64K. One of the selftests looks at the size of the ring buffer sub-buffers and writes that plus more into the trace_marker. The write will take what it can and report back what it consumed so that the user space application (like echo) will write the rest of the string. The string is stored in the ring buffer and can be read via the "trace" or "trace_pipe" files. The reading of the ring buffer uses vsnprintf(), which uses a precision "%.*s" to make sure it only reads what is stored in the buffer, as a bug could cause the string to be non terminated. With the combination of the precision change and the PAGE_SIZE of 64K allowing huge strings to be added into the ring buffer, plus the test that would actually stress that limit, a bug was reported that the precision used was too big for "%.*s" as the string was close to 64K in size and the max precision of vsnprintf is 32K. Linus suggested not to have that precision as it could hide a bug if the string was again stored without a nul byte. Another issue that was brought up is that the trace_seq buffer is also based on PAGE_SIZE even though it is not tied to the architecture limit like the ring buffer sub-buffer is. Having it be 64K * 2 is simply just too big and wasting memory on systems with 64K page sizes. It is now hardcoded to 8K which is what all other architectures with 4K PAGE_SIZE has. Finally, the write to trace_marker is now limited to 4K as there is no reason to write larger strings into trace_marker. - ring_buffer_wait() should not loop. The ring_buffer_wait() does not have the full context (yet) on if it should loop or not. Just exit the loop as soon as its woken up and let the callers decide to loop or not (they already do, so it's a bit redundant). - Fix shortest_full field to be the smallest amount in the ring buffer that a waiter is waiting for. The "shortest_full" field is updated when a new waiter comes in and wants to wait for a smaller amount of data in the ring buffer than other waiters. But after all waiters are woken up, it's not reset, so if another waiter comes in wanting to wait for more data, it will be woken up when the ring buffer has a smaller amount from what the previous waiters were waiting for. - The wake up all waiters on close is incorrectly called frome .release() and not from .flush() so it will never wake up any waiters as the .release() will not get called until all .read() calls are finished. And the wakeup is for the waiters in those .read() calls. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZe3j6xQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qmYOAQD6rPZ+ILqHmRQMZjsxaasBeVYidspY wj3fRGzwfiB6fgEAkIeA7FOrkOK0CuG8R+2AtQNF5ZjXdmfZdiYQD1/EjQU= =Hqlf -----END PGP SIGNATURE----- Merge tag 'trace-ring-buffer-v6.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Do not allow large strings (> 4096) as single write to trace_marker The size of a string written into trace_marker was determined by the size of the sub-buffer in the ring buffer.

tracing: Use .flush() call to wake up readers
The .release() function does not get called until all readers of a file
descriptor are finished.
If a thread is blocked on reading a file descriptor in ring_buffer_wait(),
and another thread closes the file descriptor, it will not wake up the
other thread as ring_buffer_wake_waiters() is called by .release(), and
that will not get called until the .read() is finished.
The issue originally showed up in trace-cmd, but the readers are actually
other processes with their own file descriptors. So calling close() would wake
up the other tasks because they are blocked on another descriptor then the
one that was closed(). But there's other wake ups that solve that issue.
When a thread is blocked on a read, it can still hang even when another
thread closed its descriptor.
This is what the .flush() callback is for. Have the .flush() wake up the
readers.

ring-buffer: Fix resetting of shortest_full
The "shortest_full" variable is used to keep track of the waiter that is
waiting for the smallest amount on the ring buffer before being woken up.
When a tasks waits on the ring buffer, it passes in a "full" value that is
a percentage. 0 means wake up on any data. 1-100 means wake up from 1% to
100% full buffer.
As all waiters are on the same wait queue, the wake up happens for the
waiter with the smallest percentage.
The problem is that the smallest_full on the cpu_buffer that stores the
smallest amount doesn't get reset when all the waiters are woken up. It
does get reset when the ring buffer is reset (echo > /sys/kernel/tracing/trace).
This means that tasks may be woken up more often then when they want to
be. Instead, have the shortest_full field get reset just before waking up
all the tasks. If the tasks wait again, they will update the shortest_full
before sleeping.
Also add locking around setting of shortest_full in the poll logic, and
change "work" to "rbwork" to match the variable name for rb_irq_work
structures that are used in other places.

KVM GUEST_MEMFD fixes for 6.8:
- Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY to
avoid creating an inconsistent ABI (KVM_MEM_GUEST_MEMFD is not writable
from userspace, so there would be no way to write to a read-only
guest_memfd).
- Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
clear that such VMs are purely for development and testing.
- Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan
is to support confidential VMs with deterministic private memory (SNP
and TDX) only in the TDP MMU.
- Fix a bug in a GUEST_MEMFD dirty logging test that caused false passes.
x86 fixes:
- Fix missing marking of a guest page as dirty when emulating an atomic access.
- Check for mmu_notifier invalidation events before faulting in the pfn,
and before acquiring mmu_lock, to avoid unnecessary work and lock
contention with preemptible kernels (including CONFIG_PREEMPT_DYNAMIC
in non-preemptible mode).
- Disable AMD DebugSwap by default, it breaks VMSA signing and will be
re-enabled with a better VM creation API in 6.10.
- Do the cache flush of converted pages in svm_register_enc_region() before
dropping kvm->lock, to avoid a race with unregistering of the same region
and the consequent use-after-free issue.

ring-buffer: Fix waking up ring buffer readers
A task can wait on a ring buffer for when it fills up to a specific
watermark. The writer will check the minimum watermark that waiters are
waiting for and if the ring buffer is past that, it will wake up all the
waiters.
The waiters are in a wait loop, and will first check if a signal is
pending and then check if the ring buffer is at the desired level where it
should break out of the loop.
If a file that uses a ring buffer closes, and there's threads waiting on
the ring buffer, it needs to wake up those threads. To do this, a
"wait_index" was used.
Before entering the wait loop, the waiter will read the wait_index. On
wakeup, it will check if the wait_index is different than when it entered
the loop, and will exit the loop if it is. The waker will only need to
update the wait_index before waking up the waiters.
This had a couple of bugs. One trivial one and one broken by design.
The trivial bug was that the waiter checked the wait_index after the
schedule() call. It had to be checked between the prepare_to_wait() and
the schedule() which it was not.
The main bug is that the first check to set the default wait_index will
always be outside the prepare_to_wait() and the schedule(). That's because
the ring_buffer_wait() doesn't have enough context to know if it should
break out of the loop.
The loop itself is not needed, because all the callers to the
ring_buffer_wait() also has their own loop, as the callers have a better
sense of what the context is to decide whether to break out of the loop
or not.
Just have the ring_buffer_wait() block once, and if it gets woken up, exit
the function and let the callers decide what to do next.

firewire-fixes-6.8-final
A fix to suppress warning about unreleased IRQ for 1394 OHCI hardware when disabling MSI In Linux kernel v6.5, a PCI driver for 1394 OHCI hardware was optimized into the managed device resources. Edmund Raile points out that the change brings the warning about unreleased IRQ at the call of pci_disable_msi(), since the API expects that the relevant IRQ has already been released in advance. As long as the API is called in .remove callback of PCI device operation, it is prohibited to maintain the IRQ as the part of managed device resource. As a workaround, the IRQ is explicitly released at .remove callback, before the call of pci_disable_msi(). The pci_disable_msi() is legacy API nowadays in PCI MSI implementation. I have a plan to replace it with the modern API in the development for the future version of Linux kernel. So at present I keep them as is. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCZevaBAAKCRCsLtaWM8Lw Ez5LAP9QEraiOsm2JxyCNMmyjWubMd58wSjdVmWW61yKxEegvwD8DPY1eosKXhDA GLWaiRbJ4YbIglEK6zDnmwAz5FYtPw8= =PVzs -----END PGP SIGNATURE----- Merge tag 'firewire-fixes-6.8-final' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fix from Takashi Sakamoto: "A fix to suppress a warning about unreleased IRQ for 1394 OHCI hardware when disabling MSI.

SEV: disable SEV-ES DebugSwap by default
The DebugSwap feature of SEV-ES provides a way for confidential guests to use
data breakpoints. However, because the status of the DebugSwap feature is
recorded in the VMSA, enabling it by default invalidates the attestation
signatures. In 6.10 we will introduce a new API to create SEV VMs that
will allow enabling DebugSwap based on what the user tells KVM to do.
Contextually, we will change the legacy KVM_SEV_ES_INIT API to never
enable DebugSwap.
For compatibility with kernels that pre-date the introduction of DebugSwap,
as well as with those where KVM_SEV_ES_INIT will never enable it, do not enable
the feature by default. If anybody wants to use it, for now they can enable
the sev_es_debug_swap_enabled module parameter, but this will result in a
warning.

KVM x86 fixes for 6.8, round 2: - When emulating an atomic access, mark the gfn as dirty in the memslot to fix a bug where KVM could fail to mark the slot as dirty during live migration, ultimately resulting in guest data corruption due to a dirty page not being re-copied from the source to the target. - Check for mmu_notifier invalidation events before faulting in the pfn, and before acquiring mmu_lock, to avoid unnecessary work and lock contention. Contending mmu_lock is especially problematic on preemptible kernels, as KVM may yield mmu_lock in response to the contention, which severely degrades overall performance due to vCPUs making it difficult for the task that triggered invalidation to make forward progress. Note, due to another kernel bug, this fix isn't limited to preemtible kernels, as any kernel built with CONFIG_PREEMPT_DYNAMIC=y will yield contended rwlocks and spinlocks. https://lore.kernel.org/all/20240110214723.695930-1-seanjc@google.com |

i2c: aspeed: Fix the dummy irq expected print
When the i2c error condition occurred and master state was not
idle, the master irq function will goto complete state without any
other interrupt handling. It would cause dummy irq expected print.
Under this condition, assign the irq_status into irq_handle.
For example, when the abnormal start / stop occurred (bit 5) with
normal stop status (bit 4) at same time. Then the normal stop status
would not be handled and it would cause irq expected print in
the aspeed_i2c_bus_irq.
...
aspeed-i2c-bus x. i2c-bus: irq handled != irq.
Expected 0x00000030, but was 0x00000020
...

i2c: wmt: Fix an error handling path in wmt_i2c_probe()
wmt_i2c_reset_hardware() calls clk_prepare_enable(). So, should an error
occur after it, it should be undone by a corresponding
clk_disable_unprepare() call, as already done in the remove function.

i2c: i801: Avoid potential double call to gpiod_remove_lookup_table
If registering the platform device fails, the lookup table is
removed in the error path. On module removal we would try to
remove the lookup table again. Fix this by setting priv->lookup
only if registering the platform device was successful.
In addition free the memory allocated for the lookup table in
the error path.

i2c: i801: Fix using mux_pdev before it's set
i801_probe_optional_slaves() is called before i801_add_mux().
This results in mux_pdev being checked before it's set by
i801_add_mux(). Fix this by changing the order of the calls.
I consider this safe as I see no dependencies.

Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removal
Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

net: pds_core: Fix possible double free in error handling path
When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), Callback function pdsc_auxbus_dev_release
calls kfree(padev) to free memory. We shouldn't call kfree(padev)
again in the error handling path.
Fix this by cleaning up the redundant kfree() and putting
the error handling back to where the errors happened.
