sma1307_check_fault_worker() stores dynamically allocated uevent strings in
envp[0]. Several fault conditions are checked in sequence, so a later fault
can overwrite envp[0] before the final kfree() and leak the previous
allocation.
The same flow can leave an OT1 volume entry in envp[1] while envp[0]
has been overwritten by a later non-OT1 fault, causing an inconsistent
uevent payload.
Use static STATUS strings and a stack buffer for the optional VOLUME entry.
This removes the allocations from the worker and keeps VOLUME tied only
to the OT1 events that produce it.

Peter Ujfalusi <peter.ujfalusi@linux.intel.com> says:
This series hardens SOF kcontrol data paths for both IPC3 and IPC4 by
fixing size-handling bugs in put/get/update flows and tightening bounds
checks around firmware/user-provided payload lengths.
The changes include:
Fix TOCTOU-style size misuse in IPC3/IPC4 bytes put paths by validating and
using the incoming payload size.
Add notification/update payload size validation before parsing control data.
Use overflow-checked arithmetic when computing expected IPC3 control sizes.
Ensure update/copy bounds are validated against actual allocation limits.
Fix IPC3 bytes_ext bounds checks to account for struct header offset, closing
a heap overflow/over-read issue from unprivileged userspace TLV access.
Overall, the series makes control payload processing robust against malformed or
inconsistent sizes and prevents out-of-bounds accesses.

The ipc_control_data buffer is allocated as kzalloc(max_size), where
max_size covers the entire struct sof_ipc_ctrl_data including its
flexible array payload. However, the bounds checks in bytes_ext_put
and _bytes_ext_get compared user data lengths against max_size
directly, ignoring that cdata->data sits at an offset of
sizeof(struct sof_ipc_ctrl_data) bytes into the allocation.
This allowed writing up to sizeof(struct sof_ipc_ctrl_data) bytes past
the end of the heap buffer from unprivileged userspace via the ALSA TLV
kcontrol interface, and similarly allowed over-reading adjacent heap
data on the get path.
Fix all bounds checks to subtract sizeof(*cdata) from max_size so they
reflect the actual space available at the cdata->data offset. Also fix
the error-path restore in bytes_ext_put which wrote to cdata->data
instead of cdata, causing the same overflow.

In sof_ipc3_bytes_put(), the size used for the memcpy is derived from
the old data->size already in the buffer, not the incoming new data's
size field. If the new data has a different size, the copy length is
wrong: it may truncate valid data or copy stale bytes.
Similarly, sof_ipc3_bytes_get() checks data->size against max_size
without accounting for the sizeof(struct sof_ipc_ctrl_data) offset
of the flex array within the allocation.
Fix bytes_put to validate and use the incoming data's sof_abi_hdr.size
from ucontrol before copying. Fix bytes_get to subtract sizeof(*cdata)
from the bounds check to match the actual available space.

In sof_ipc3_control_update(), the expected_size calculation uses

After commit 0652a3daa7 ("tracing: Fix CFI violation in probestub

get_kernel_nofault() is called in the generic version of

"Weekly drm fixes, not contributing to things settling down
unfortunately. Lots of driver fixes for various bounds checks, leaks
and UAF type things, i915/xe probably the most sane, amdgpu has a mix
of fixes all over, then ethosu has lots of small fixes.
The problem of fixing thing in private has really hit us with the
change handle ioctl, and "Sima was right" and we should have disabled
the ioctl, since it was only introduced a couple of kernels ago and
failed to upstream it's tests in time.
The patch here fixes the problems Sima identified, but disables the
ioctl as well, with a list of known problems in it and a request for
proper tests to be written and upstreamed. It's a niche user ioctl
designed for CRIU with AMD ROCm, so I think it's fine to just disable
it.
Maybe this week will settle down.

[airlied: just added some comments on how to reenable]
On-list because the cat is out of the bag and we're clearly not good
enough to figure this out in private. The story thus far:
5e28b7b944 ("drm: Set old handle to NULL before prime swap in
change_handle") tried to fix a race condition between the gem_close and
gem_change_handle ioctls, but got a few things wrong:
- There's a confusion with the local variable handle, which is actually
the new handle, and so the two-stage trick was actually applied to the
wrong idr slot. 7164d78559 ("drm/gem: fix race between
change_handle and handle_delete") tried to fix that by adding yet
another code block, but forgot to add the error handling. Which meant
we now have two paths, both kinda wrong.
- dc366607c4 ("drm: Replace old pointer to new idr") tried to apply
another fix, but inconsistently, again because of the handle confusion
- this would be the right fix (kinda, somewhat, it's a mess) if we'd
do the two-stage approach for the new handle. Except that wasn't the
intent of the original fix.
We also didn't have an igt merged for the original ioctl, which is a big
no-go. This was attempted to address off-list in the original bugfix,
and amd QA people claimed the bug was fixed now. Very clearly that's not
the case. Here's my attempt to sort this out:
- Rename the local variable to new_handle, the old aliasing with
args->handle is just too dangerously confusing.
- Merge the gem obj lookup with the two-stage idr_replace so that we
avoid getting ourselves confused there.
- This means we don't have a surplus temporary reference anymore, only
an inherited from the idr. A concurrent gem_close on the new_handle
could steal that. Fix that with the same two-stage approach
create_tail uses. This is a bit overkill as documented in the comment,
but I also don't trust my ability to understand this all correctly, so
go with the established pattern we have from other ioctls instead for
maximum paranoia.
- Adjust error paths. I've tried to make the error and success paths
common, because they are identical except for which handle is removed
and on which we call idr_replace to (re)install the object again. But
that made things messier to read, so I've left it at the more verbose
version, which unfortunately hides the symmetry in the entire code
flow a bit.
- While at it, also replace the 7 space indent with 1 tab.
And finally, because I flat out don't trust my abilities here at all
anymore:
- Disable the ioctl until we have the igt situation and everything else
sorted out on-list and with full consensus.
v2:
Sashiko noticed that I didn't handle the error path for idr_replace
correctly, it must be checked with IS_ERR_OR_NULL like in
gem_handle_delete. So yeah, definitely should just the existing paths
1:1 because this is endless amounts of tricky.
Also add the Fixes: line for the original ioctl, I forgot that too.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"arm64:
- Correctly drop the ITS translation cache reference when it actually
gets invalidated
- Take the SRCU lock for SW page table walks
- Restore POR_EL0 access to host EL0, avoiding POR_EL0 becoming
inaccessible from EL0 after running a guest
- Reassign nested_mmus array behind mmu_lock, ensuring that vcpu init
and MMU notifiers are mutually exclusive
- Correctly handle FEAT_XNX at stage-2
s390:
- More fixes for the new page table management and nested
virtualization
x86:
- More fixes for GHCB issues:
- Read start/end indices of page size change requests exactly once
per vmexit
- Unmap and unpin the GHCB as needed on vCPU free"

Merge tag 'probes-fixes-v7.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing/probes fix from Masami Hiramatsu:
"Fix the eprobe event parser to point error position correctly"
* tag 'probes-fixes-v7.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing/probes: Point the error offset correctly for eprobe argument error
The err_repeated_inc test was added with an expected stderr fixture
that does not match the diagnostic printed by kconfig.
Running "make testconfig" currently fails in that test even though the
parser reports the duplicated include correctly:
[stderr]
Kconfig.inc1:4: error: repeated inclusion of Kconfig.inc3
Kconfig.inc2:3: note: location of first inclusion of Kconfig.inc3
The fixture expects "Repeated" and "Location" with capital letters, but
the diagnostic emitted by scripts/kconfig/util.c uses lowercase words.
Update the fixture to match the real message.
Fixes: 102d712ded ("kconfig: Error out on duplicated kconfig inclusion")
