Pull driver core api addition from Greg KH:
"Here is a driver core new api for 6.14-rc3 that is being added to
allow platform devices from stop being abused.
It adds a new 'faux_device' structure and bus and api to allow almost
a straight or simpler conversion from platform devices that were not
really a platform device. It also comes with a binding for rust, with
an example driver in rust showing how it's used.
I'm adding this now so that the patches that convert the different
drivers and subsystems can all start flowing into linux-next now
through their different development trees, in time for 6.15-rc1.
We have a number that are already reviewed and tested, but adding
those conversions now doesn't seem right. For now, no one is using
this, and it passes all build tests from 0-day and linux-next, so all
should be good"

Pull kvm fixes from Paolo Bonzini:
"ARM:
- Large set of fixes for vector handling, especially in the
interactions between host and guest state.
This fixes a number of bugs affecting actual deployments, and
greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland
for dealing with this thankless task.
- Fix an ugly race between vcpu and vgic creation/init, resulting in
unexpected behaviours
- Fix use of kernel VAs at EL2 when emulating timers with nVHE
- Small set of pKVM improvements and cleanups
x86:
- Fix broken SNP support with KVM module built-in, ensuring the PSP
module is initialized before KVM even when the module
infrastructure cannot be used to order initcalls
- Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being
emulated by KVM to fix a NULL pointer dereference
- Enter guest mode (L2) from KVM's perspective before initializing
the vCPU's nested NPT MMU so that the MMU is properly tagged for
L2, not L1
- Load the guest's DR6 outside of the innermost .vcpu_run() loop, as
the guest's value may be stale if a VM-Exit is handled in the
fastpath"

Pull trace ring buffer fixes from Steven Rostedt:
- Enable resize on mmap() error
When a process mmaps a ring buffer, its size is locked and resizing
is disabled. But if the user passes in a wrong parameter, the mmap()
can fail after the resize was disabled and the mmap() exits with
error without reenabling the ring buffer resize. This prevents the
ring buffer from ever being resized after that. Reenable resizing of
the ring buffer on mmap() error.
- Have resizing return proper error and not always -ENOMEM
If the ring buffer is mmapped by one task and another task tries to
resize the buffer it will error with -ENOMEM. This is confusing to
the user as there may be plenty of memory available. Have it return
the error that actually happens (in this case -EBUSY) where the user
can understand why the resize failed.
- Test the sub-buffer array to validate persistent memory buffer
On boot up, the initialization of the persistent memory buffer will
do a validation check to see if the content of the data is valid, and
if so, it will use the memory as is, otherwise it re-initializes it.
There's meta data in this persistent memory that keeps track of which
sub-buffer is the reader page and an array that states the order of
the sub-buffers. The values in this array are indexes into the
sub-buffers. The validator checks to make sure that all the entries
in the array are within the sub-buffer list index, but it does not
check for duplications.
While working on this code, the array got corrupted and had
duplicates, where not all the sub-buffers were accounted for. This
passed the validator as all entries were valid, but the link list was
incorrect and could have caused a crash. The corruption only produced
incorrect data, but it could have been more severe. To fix this,
create a bitmask that covers all the sub-buffer indexes and set it to
all zeros. While iterating the array checking the values of the array
content, have it set a bit corresponding to the index in the array.
If the bit was already set, then it is a duplicate and mark the
buffer as invalid and reset it.
- Prevent mmap()ing persistent ring buffer
The persistent ring buffer uses vmap() to map the persistent memory.
Currently, the mmap() logic only uses virt_to_page() to get the page
from the ring buffer memory and use that to map to user space. This
works because a normal ring buffer uses alloc_page() to allocate its
memory. But because the persistent ring buffer use vmap() it causes a
kernel crash.
Fixing this to work with vmap() is not hard, but since mmap() on
persistent memory buffers never worked, just have the mmap() return
-ENODEV (what was returned before mmap() for persistent memory ring
buffers, as they never supported mmap. Normal buffers will still
allow mmap(). Implementing mmap() for persistent memory ring buffers
can wait till the next merge window.
- Fix polling on persistent ring buffers
There's a "buffer_percent" option (default set to 50), that is used
to have reads of the ring buffer binary data block until the buffer
fills to that percentage. The field "pages_touched" is incremented
every time a new sub-buffer has content added to it. This field is
used in the calculations to determine the amount of content is in the
buffer and if it exceeds the "buffer_percent" then it will wake the
task polling on the buffer.
As persistent ring buffers can be created by the content from a
previous boot, the "pages_touched" field was not updated. This means
that if a task were to poll on the persistent buffer, it would block
even if the buffer was completely full. It would block even if the
"buffer_percent" was zero, because with "pages_touched" as zero, it
would be calculated as the buffer having no content. Update
pages_touched when initializing the persistent ring buffer from a
previous boot.

ring-buffer: Update pages_touched to reflect persistent buffer content
tracing: Do not allow mmap() of persistent ring buffer
ring-buffer: Validate the persistent meta data subbuf array
tracing: Have the error of __tracing_resize_ring_buffer() passed to user
ring-buffer: Unlock resize on mmap error
|
|
The pages_touched field represents the number of subbuffers in the ring
buffer that have content that can be read. This is used in accounting of
"dirty_pages" and "buffer_percent" to allow the user to wait for the
buffer to be filled to a certain amount before it reads the buffer in
blocking mode.
The persistent buffer never updated this value so it was set to zero, and
this accounting would take it as it had no content. This would cause user
space to wait for content even though there's enough content in the ring
buffer that satisfies the buffer_percent.
