epoll can call out to vfs_poll() with a file pointer that may race with
the last 'fput()'. That would make f_count go down to zero, and while
the ep->mtx locking means that the resulting file pointer tear-down will
be blocked until the poll returns, it means that f_count is already
dead, and any use of it won't actually get a reference to the file any
more: it's dead regardless.
Make sure we have a valid ref on the file pointer before we call down to
vfs_poll() from the epoll routines.

- Fix RCU callback of freeing an eventfs_inode.
The freeing of the eventfs_inode from the kref going to zero
freed the contents of the eventfs_inode and then used kfree_rcu()
to free the inode itself. But the contents should also be protected
by RCU. Switch to a call_rcu() that calls a function to free all
of the eventfs_inode after the RCU synchronization.
- The tracing subsystem maps its own descriptor to a file represented by
eventfs. The freeing of this descriptor needs to know when the
last reference of an eventfs_inode is released, but currently
there is no interface for that. Add a "release" callback to
the eventfs_inode entry array that allows for freeing of data
that can be referenced by the eventfs_inode being opened.
Then increment the ref counter for this descriptor when the
eventfs_inode file is created, and decrement/free it when the
last reference to the eventfs_inode is released and the file
is removed. This prevents races between freeing the descriptor
and the opening of the eventfs file.
- Fix the permission processing of eventfs.
The change to make the permissions of eventfs default to the mount
point but keep track of when changes were made had a side effect
that could cause security concerns. When the tracefs is remounted
with a given gid or uid, all the files within it should inherit
that gid or uid. But if the admin had changed the permission of
some file within the tracefs file system, it would not get updated
by the remount. This caused the kselftest of file permissions
to fail the second time it is run. The first time, all changes
would look fine, but the second time, because the changes were
"saved", the remount did not reset them.
Create a link list of all existing tracefs inodes, and clear the
saved flags on them on a remount if the remount changes the
corresponding gid or uid fields.
This also simplifies the code by removing the distinction between the
toplevel eventfs and an instance eventfs. They should both act the
same. They were different because of a misconception due to the
remount not resetting the flags. Now that remount resets all the
files and directories to default to the root node if a uid/gid is
specified, it makes the logic simpler to implement.

The type defined for the BINDER_SET_MAX_THREADS ioctl was changed from
size_t to __u32 in order to avoid incompatibility issues between 32 and

In gb_interface_create, &intf->mode_switch_completion is bound with
gb_interface_mode_switch_work. Then it will be started by
gb_interface_request_mode_switch. Here is the relevant code.
if (!queue_work(system_long_wq, &intf->mode_switch_work)) {
...
}
If we call gb_interface_release to make cleanup, there may be an
unfinished work. This function will call kfree to free the object
"intf". However, if gb_interface_mode_switch_work is scheduled to
run after kfree, it may cause use-after-free error as
gb_interface_mode_switch_work will use the object "intf".
The possible execution flow that may lead to the issue is as follows:
CPU0 CPU1
| gb_interface_create
| gb_interface_request_mode_switch
gb_interface_release |
kfree(intf) (free) |
| gb_interface_mode_switch_work
| mutex_lock(&intf->mutex) (use)
Fix it by canceling the work before kfree.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Package messages from ftrace source with SyS-T Structured Binary Data
(later SBD) header and 64-bit ID. This provides modification-free
compatibility between ftrace and SyS-T arguments structure by applying
0xFFFF mask on message ID.
This happens due to the fact that SBD and ftrace structures have the
same principle of data storage: <header><args binary blob>.
The headers are bit-to-bit compatible and both contain event/catalog ID
with the exception, that ftrace header contains more fields within 64
bits which needs to be masked during encoding process, since SBD
standard doesn't support mask of ID field.

Pass stm source type via stm_write() to allow different handling on
protocol level.
The measure above should allow protocol level encoder to differentiate
and accordingly pack the messages. As an example SyS-T might get use of
ftrace message ID's and instead of applying regular header, pack them
as SyS-T catalog or SyS-T Structured Binary Data message to allow proper

Currently kernel HW tracing infrastrtucture and specifically its SyS-T
part treats all source data in the same way. Treating and encoding
different trace data sources differently might allow decoding software
to make use of e.g. ftrace event ids by converting them to a SyS-T
message catalog.
The solution is to keep source type stored within stm_source_data
structure to allow different handling by stm output/protocol.
Currently we only differentiate between STM_USER and STM_FTRACE sources.

The events directory gets its permissions from the root inode. But this
can cause an inconsistency if the instances directory changes its
permissions, as the permissions of the created directories under it should
inherit the permissions of the instances directory when directories under
it are created.
Currently the behavior is:
# cd /sys/kernel/tracing
# chgrp 1002 instances
# mkdir instances/foo
# ls -l instances/foo
[..]
-r--r----- 1 root lkp 0 May 1 18:55 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 18:55 current_tracer
-rw-r----- 1 root lkp 0 May 1 18:55 error_log
drwxr-xr-x 1 root root 0 May 1 18:55 events
--w------- 1 root lkp 0 May 1 18:55 free_buffer
drwxr-x--- 2 root lkp 0 May 1 18:55 options
drwxr-x--- 10 root lkp 0 May 1 18:55 per_cpu
-rw-r----- 1 root lkp 0 May 1 18:55 set_event
All the files and directories under "foo" has the "lkp" group except the
"events" directory. That's because its getting its default value from the
mount point instead of its parent.
Have the "events" directory make its default value based on its parent's
permissions. That now gives:
# ls -l instances/foo
[..]

Treat the events directory the same as other directories when it comes to
permissions. The events directory was considered different because it's
dentry is persistent, whereas the other directory dentries are created
when accessed. But the way tracefs now does its ownership by using the
root dentry's permissions as the default permissions, the events directory
can get out of sync when a remount is performed setting the group and user
permissions.
Remove the special case for the events directory on setting the
attributes. This allows the updates caused by remount to work properly as
well as simplifies the code.

If the instances directory's permissions were never change, then have it
and its children use the mount point permissions as the default.
Currently, the permissions of instance directories are determined by the
instance directory's permissions itself. But if the tracefs file system is
remounted and changes the permissions, the instance directory and its
children should use the new permission.
But because both the instance directory and its children use the instance
directory's inode for permissions, it misses the update.
To demonstrate this:
# cd /sys/kernel/tracing/
# mkdir instances/foo
# ls -ld instances/foo
drwxr-x--- 5 root root 0 May 1 19:07 instances/foo
# ls -ld instances
drwxr-x--- 3 root root 0 May 1 18:57 instances
# ls -ld current_tracer
-rw-r----- 1 root root 0 May 1 18:57 current_tracer
# mount -o remount,gid=1002 .
# ls -ld instances
drwxr-x--- 3 root root 0 May 1 18:57 instances
# ls -ld instances/foo/
drwxr-x--- 5 root root 0 May 1 19:07 instances/foo/
# ls -ld current_tracer
-rw-r----- 1 root lkp 0 May 1 18:57 current_tracer
Notice that changing the group id to that of "lkp" did not affect the
instances directory nor its children. It should have been:
# ls -ld current_tracer
-rw-r----- 1 root root 0 May 1 19:19 current_tracer
# ls -ld instances/foo/
drwxr-x--- 5 root root 0 May 1 19:25 instances/foo/
# ls -ld instances
drwxr-x--- 3 root root 0 May 1 19:19 instances
# mount -o remount,gid=1002 .
# ls -ld current_tracer
-rw-r----- 1 root lkp 0 May 1 19:19 current_tracer
# ls -ld instances
drwxr-x--- 3 root lkp 0 May 1 19:19 instances
# ls -ld instances/foo/
drwxr-x--- 5 root lkp 0 May 1 19:25 instances/foo/
Where all files were updated by the remount gid update.

There's an inconsistency with the way permissions are handled in tracefs.
Because the permissions are generated when accessed, they default to the
root inode's permission if they were never set by the user. If the user
sets the permissions, then a flag is set and the permissions are saved via
the inode (for tracefs files) or an internal attribute field (for
eventfs).
But if a remount happens that specify the permissions, all the files that
were not changed by the user gets updated, but the ones that were are not.
If the user were to remount the file system with a given permission, then
all files and directories within that file system should be updated.
This can cause security issues if a file's permission was updated but the
admin forgot about it. They could incorrectly think that remounting with
permissions set would update all files, but miss some.
For example:
# cd /sys/kernel/tracing
# chgrp 1002 current_tracer
# ls -l
[..]
-rw-r----- 1 root root 0 May 1 21:25 buffer_size_kb
-rw-r----- 1 root root 0 May 1 21:25 buffer_subbuf_size_kb
-r--r----- 1 root root 0 May 1 21:25 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:25 current_tracer
-rw-r----- 1 root root 0 May 1 21:25 dynamic_events
-r--r----- 1 root root 0 May 1 21:25 dyn_ftrace_total_info
-r--r----- 1 root root 0 May 1 21:25 enabled_functions
Where current_tracer now has group "lkp".
# mount -o remount,gid=1001 .
# ls -l
-rw-r----- 1 root tracing 0 May 1 21:25 buffer_size_kb
-rw-r----- 1 root tracing 0 May 1 21:25 buffer_subbuf_size_kb
-r--r----- 1 root tracing 0 May 1 21:25 buffer_total_size_kb
-rw-r----- 1 root lkp 0 May 1 21:25 current_tracer
-rw-r----- 1 root tracing 0 May 1 21:25 dynamic_events
-r--r----- 1 root tracing 0 May 1 21:25 dyn_ftrace_total_info
-r--r----- 1 root tracing 0 May 1 21:25 enabled_functions
Everything changed but the "current_tracer".
Add a new link list that keeps track of all the tracefs_inodes which has
the permission flags that tell if the file/dir should use the root inode's
permission or not. Then on remount, clear all the flags so that the
default behavior of using the root inode's permission is done for all
files and directories.

The freeing of eventfs_inode via a kfree_rcu() callback. But the content
of the eventfs_inode was being freed after the last kref. This is
dangerous, as changes are being made that can access the content of an
eventfs_inode from an RCU loop.
Instead of using kfree_rcu() use call_rcu() that calls a function to do
all the freeing of the eventfs_inode after a RCU grace period has expired.

Synthetic events create and destroy tracefs files when they are created
and removed. The tracing subsystem has its own file descriptor
representing the state of the events attached to the tracefs files.
There's a race between the eventfs files and this file descriptor of the
tracing system where the following can cause an issue:
With two scripts 'A' and 'B' doing:
Script 'A':
echo "hello int aaa" > /sys/kernel/tracing/synthetic_events
while :
do
echo 0 > /sys/kernel/tracing/events/synthetic/hello/enable
done
Script 'B':
echo > /sys/kernel/tracing/synthetic_events
Script 'A' creates a synthetic event "hello" and then just writes zero
into its enable file.
Script 'B' removes all synthetic events (including the newly created
"hello" event).
What happens is that the opening of the "enable" file has:
{
struct trace_event_file *file = inode->i_private;
int ret;
ret = tracing_check_open_get_tr(file->tr);
[..]
But deleting the events frees the "file" descriptor, and a "use after
free" happens with the dereference at "file->tr".
The file descriptor does have a reference counter, but there needs to be a
way to decrement it from the eventfs when the eventfs_inode is removed
that represents this file descriptor.
Add an optional "release" callback to the eventfs_entry array structure,
that gets called when the eventfs file is about to be removed. This allows
for the creating on the eventfs file to increment the tracing file
descriptor ref counter. When the eventfs file is deleted, it can call the
release function that will call the put function for the tracing file
descriptor.
This will protect the tracing file from being freed while a eventfs file

The usual mixed bag from towards the end of the cycle.
Changes since take 1. Fixed the fixes tag and indeed fixed a rebase I
messed up on the same fix.
New devices support
===================
invensense,icm42600
- Support the ICM-42686-P a high range device going up to 32g and 4000 dps
New features
============
adi,ad7944
- Add support for chain mode in which many ADCs may be daisy chained and
read out via a single long read.
adi,ad9467/backend library
- Add bus tuning related interfaces.
adi,axi-adc
- Add control for the AXI clock - seems always enabled early in boot for other
reasons, but the driver should not rely on that..
Cleanups and minor or late breaking fixes
=========================================
Micrsoft/ACPI mount matrix handling.
- Replace several implementations of the Microsoft defined ROTM ACPI
method with a single one.
multiple drivers
- Don't call the result of wait_for_completion() timeout as it's
more accurate as time_left.
adi,ad7266
- Stop setting the iio_dev->masklength as it's done by the IIO core and
should not be set from drivers.
adi,ad799x
- Some checkpatch type fixes.

- Ensure compelte MU_CNT1 is written during lock phase.
adi,axi-dac
- Fix inverted parameter.

and adaptive thresholds that the driver accepts.
freescale,mxs-lradc
- Stop setting the iio_dev->masklength as it's done by the IIO core and
should not be set from drivers.
invensense,timestamp library
- Fix timestamp vs interupt alignment and aovid soms glitches that
occured when switching sampling frequency.
microchip,mcp3564
- Make use of device_for_each_child_node_scoped() to allow early release
without manual fwnode_handle_put().

Merge tag 'cxl-fixes-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull cxl fix from Dave Jiang:
"Add missing RCH support for endpoint access_coordinate calculation.
A late bug was reported by Robert Richter that the Restricted CXL Host
(RCH) support was missing in the CXL endpoint access_coordinate
calculation.
The missing support causes the topology iterator to stumble over a
NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1
support.
The fix bypasses RCH topology as the access_coordinate calculation is
not necessary since RCH does not support hotplug and the memory region
exported should be covered by the HMAT table already.
A unit test is also added to cxl_test to check against future
regressions on the topology iterator"

Merge tag 'block-6.9-20240503' of git://git.kernel.dk/linux
Pull block fixes from Jens Axboe:

fixes, and a single fix for ublk not setting segment count and size
limits"
* tag 'block-6.9-20240503' of git://git.kernel.dk/linux:
nvme-tcp: strict pdu pacing to avoid send stalls on TLS
nvmet: fix nvme status code when namespace is disabled
nvmet-tcp: fix possible memory leak when tearing down a controller
nvme: cancel pending I/O if nvme controller is in terminal state
nvmet-auth: replace pr_debug() with pr_err() to report an error.

nvme: find numa distance only if controller has valid numa id
ublk: remove segment count and size limits
nvme: fix warn output about shared namespaces without CONFIG_NVME_MULTIPATH
As usual in a late stage, we received a fair amount of fixes for ASoC,
and it became bigger than wished. But all fixes are rather device-
specific, and they look pretty safe to apply.
A major par of changes are series of fixes for ASoC meson and SOF
drivers as well as for Realtek and Cirrus codecs. In addition,
recent emu10k1 regression fixes and usual HD-audio quirks are
included.
