- Add needed READ_ONCE() around access to the fgraph array element
The updates to the fgraph array can happen when callbacks are registered
and unregistered. The __ftrace_return_to_handler() can handle reading
either the old value or the new value. But once it reads that value
it must stay consistent otherwise the check that looks to see if the
value is a stub may show false, but if the compiler decides to re-read
after that check, it can be true which can cause the code to crash
later on.
- Make function profiler use the top level ops for filtering again
When function graph became available for instances, its filter ops became
independent from the top level set_ftrace_filter. In the process the
function profiler received its own filter ops as well. But the function
profiler uses the top level set_ftrace_filter file and does not have one
of its own. In giving it its own filter ops, it lost any user interface
it once had. Make it use the top level set_ftrace_filter file again.
This fixes a regression.

Commit c132be2c4f ("function_graph: Have the instances use their own
ftrace_ops for filtering"), function profiler (enabled via
function_profile_enabled) has been showing statistics for all functions,
ignoring set_ftrace_filter settings.
While tracers are instantiated, the function profiler is not. Therefore, it
should use the global set_ftrace_filter for consistency. This patch
modifies the function profiler to use the global filter, fixing the
filtering functionality.

In __ftrace_return_to_handler(), a loop iterates over the fgraph_array[]
elements, which are fgraph_ops. The loop checks if an element is a
fgraph_stub to prevent using a fgraph_stub afterward.
However, if the compiler reloads fgraph_array[] after this check, it might
race with an update to fgraph_array[] that introduces a fgraph_stub. This
could result in the stub being processed, but the stub contains a null
"func_hash" field, leading to a NULL pointer dereference.
To ensure that the gops compared against the fgraph_stub matches the gops
processed later, add a READ_ONCE(). A similar patch appears in commit
63a8dfb ("function_graph: Add READ_ONCE() when accessing fgraph_array[]").

1) Allow a GGTT mapped batch to be submitted to user exec queue
For a OA use case, one of the HW registers needs to be modified by
submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so
that the register is modified in the user's hardware context. In order
to do this a batch that is mapped in GGTT, needs to be submitted to the
user exec queue. Since all user submissions use q->vm and hence PPGTT,
add some plumbing to enable submission of batches mapped in GGTT.
v2: ggtt is zero-initialized, so no need to set it false (Matt Brost)
2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC
To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set.
Setting this bit cause the context image size to change and if not done
correct, can cause undesired hangs.
Current code uses a separate exec_queue to modify this bit and is
error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to
the target hardware context to modify the relevant bit.
In v2 version, an attempt to submit everything to the user-queue was
made, but it failed the unprivileged-single-ctx-counters test. It
appears that the OACTXCONTROL must be modified from a remote context.
In v3 version, all context specific register configurations were moved
to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a
cleaner way, since we can now submit all configuration to user
exec_queue and the fence handling is simplified.
v2:
(Matt)
- set job->ggtt to true if create job is successful
- unlock vm on job error
(Ashutosh)
- don't wait on job submission
- use kernel exec queue where possible
v3:
(Ashutosh)
- Fix checkpatch issues
- Remove extra spaces/new-lines
- Add Fixes: and Cc: tags
- Reset context control bit when OA stream is closed
- Submit all config via MI_LOAD_REGISTER_IMMEDIATE

- Update commit message for v3 experiment
- Squash patches for easier port to stable
v4:

v5:

- Fix trace event string check when dealing with array of strings
The xe_bo_move event has a field that indexes into an array of
strings. The TP_fast_assign() added the index into the ring buffer
and the TP_printk() had a "%s" that referenced the array using the
index in the ring buffer. This is a legitimate use of "%s" in
trace events. But this triggered a false positive in the
test_event_printk() at boot saying that the string was dangerous.
Change the check to allow arrays using fields in the ring buffer
as an index to be considered a safe string.

Pull tracing fix from Steven Rostedt:
"Fix trace event string check when dealing with array of strings
The xe_bo_move event has a field that indexes into an array of
strings. The TP_fast_assign() added the index into the ring buffer and
the TP_printk() had a "%s" that referenced the array using the index
in the ring buffer. This is a legitimate use of "%s" in trace events.
But this triggered a false positive in the test_event_printk() at boot
saying that the string was dangerous.
Change the check to allow arrays using fields in the ring buffer as an
index to be considered a safe string"
* tag 'trace-v6.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
tracing: Have process_string() also allow arrays
When the kernel is built without UMP support but a user-space app
requires the midi_version > 0, the kernel should return an error.
Otherwise user-space assumes as if it were possible to deal,
eventually hitting serious errors later.

000C is a new platform that will also have an ALC285 codec and needs the

In order to catch a common bug where a TRACE_EVENT() TP_fast_assign()
assigns an address of an allocated string to the ring buffer and then
references it in TP_printk(), which can be executed hours later when the
string is free, the function test_event_printk() runs on all events as
they are registered to make sure there's no unwanted dereferencing.
It calls process_string() to handle cases in TP_printk() format that has
"%s". It returns whether or not the string is safe. But it can have some
false positives.
For instance, xe_bo_move() has:
TP_printk("move_lacks_source:%s, migrate object %p [size %zu] from %s to %s device_id:%s",
__entry->move_lacks_source ? "yes" : "no", __entry->bo, __entry->size,
xe_mem_type_to_name[__entry->old_placement],
xe_mem_type_to_name[__entry->new_placement], __get_str(device_id))
Where the "%s" references into xe_mem_type_to_name[]. This is an array of
pointers that should be safe for the event to access. Instead of flagging
this as a bad reference, if a reference points to an array, where the
record field is the index, consider it safe.

This reverts commit c2d188e137.
Although it's fine to filter the invalid UMP groups at the first probe
time, this will become a problem when UMP groups are updated and
(re-)activated. Then there is no way to re-add the substreams
properly for the legacy rawmidi, and the new active groups will be
still invisible.
So let's revert the change. This will move back to showing the full
16 groups, but it's better than forever lost.

OSS sequencer handles the SysEx messages split in 6 bytes packets, and
ALSA sequencer OSS layer tries to combine those. It stores the data
in the internal buffer and this access is racy as of now, which may
lead to the out-of-bounds access.
As a temporary band-aid fix, introduce a mutex for serializing the
process of the SysEx message packets.

The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN
thermal profile and requires the timed profile quirk.
Upon adding this ID to both the omen_thermal_profile_boards and
omen_timed_thermal_profile_boards, significant bump in performance can be
observed. For instance, SilverBench (https://silver.urih.com/) results
improved from ~56,000 to ~69,000, as a result of higher power draws (and
thus core frequencies) whilst under load:
Package Power:
- Before the patch: ~65W (dropping to about 55W under sustained load).
- After the patch: ~115W (dropping to about 105W under sustained load).
Core Power:
- Before: ~60W (ditto above).
- After: ~108W (ditto above).
Add 8A15 to omen_thermal_profile_boards and
omen_timed_thermal_profile_boards to improve performance.

set_memory_decrypted() to fail such that an error is returned
and the resulting memory is shared. Callers need to take care
to handle these errors to avoid returning decrypted (shared)
memory to the page allocator, which could lead to functional
or security issues.
Leak the decrypted memory when set_memory_decrypted() fails,
and don't need to print an error since set_memory_decrypted()
will call WARN_ONCE().

An indirect branch instruction sets the CPU indirect branch tracker
(IBT) into WAIT_FOR_ENDBRANCH (WFE) state and WFE stays asserted
across the instruction boundary. When the decoder finds an
inappropriate instruction while WFE is set ENDBR, the CPU raises a #CP
fault.
For the "kernel IBT no ENDBR" selftest where #CPs are deliberately
triggered, the WFE state of the interrupted context needs to be
cleared to let execution continue. Otherwise when the CPU resumes
from the instruction that just caused the previous #CP, another
missing-ENDBRANCH #CP is raised and the CPU enters a dead loop.
This is not a problem with IDT because it doesn't preserve WFE and
IRET doesn't set WFE. But FRED provides space on the entry stack
(in an expanded CS area) to save and restore the WFE state, thus the
WFE state is no longer clobbered, so software must clear it.
Clear WFE to avoid dead looping in ibt_clear_fred_wfe() and the
!ibt_fatal code path when execution is allowed to continue.
Clobbering WFE in any other circumstance is a security-relevant bug.

Before commit:
f5d39b0208 ("freezer,sched: Rewrite core freezer logic")
the frozen task stat was reported as 'D' in cgroup v1.
However, after rewriting the core freezer logic, the frozen task stat is
reported as 'R'. This is confusing, especially when a task with stat of
'S' is frozen.
This bug can be reproduced with these steps:
$ cd /sys/fs/cgroup/freezer/
$ mkdir test
$ sleep 1000 &
[1] 739 // task whose stat is 'S'
$ echo 739 > test/cgroup.procs
$ echo FROZEN > test/freezer.state
$ ps -aux | grep 739
root 739 0.1 0.0 8376 1812 pts/0 R 10:56 0:00 sleep 1000
As shown above, a task whose stat is 'S' was changed to 'R' when it was
frozen.
To solve this regression, simply maintain the same reported state as
before the rewrite.
