7541015675 ANDROID: GKI: remove export of tracing control functions
Android GKI kernel modules should NOT have the ability to control the
system-wide tracing functionality, nor query to determine if it is on or
not.  So remove the exports of these functions.

Upstream does not wish to do this, so an Android-only change is
required.  See the bug id for details.

6a42eb0d21 tracing: Inform kmemleak of saved_cmdlines allocation
commit 2394ac4145ea91b92271e675a09af2a9ea6840b7 upstream.

The allocation of the struct saved_cmdlines_buffer structure changed from:

        s = kmalloc(sizeof(*s), GFP_KERNEL);
	s->saved_cmdlines = kmalloc_array(TASK_COMM_LEN, val, GFP_KERNEL);

to:

	orig_size = sizeof(*s) + val * TASK_COMM_LEN;
	order = get_order(orig_size);
	size = 1 << (order + PAGE_SHIFT);
	page = alloc_pages(GFP_KERNEL, order);
	if (!page)
		return NULL;

	s = page_address(page);
	memset(s, 0, sizeof(*s));

	s->saved_cmdlines = kmalloc_array(TASK_COMM_LEN, val, GFP_KERNEL);

Where that s->saved_cmdlines allocation looks to be a dangling allocation
to kmemleak. That's because kmemleak only keeps track of kmalloc()
allocations. For allocations that use page_alloc() directly, the kmemleak
needs to be explicitly informed about it.

Add kmemleak_alloc() and kmemleak_free() around the page allocation so
that it doesn't give the following false positive:

8a744f925d tracing: Fix wasted memory in saved_cmdlines logic
commit 44dc5c41b5b1267d4dd037d26afc0c4d3a568acb upstream.

While looking at improving the saved_cmdlines cache I found a huge amount
of wasted memory that should be used for the cmdlines.

The tracing data saves pids during the trace. At sched switch, if a trace
occurred, it will save the comm of the task that did the trace. This is
saved in a "cache" that maps pids to comms and exposed to user space via
the /sys/kernel/tracing/saved_cmdlines file. Currently it only caches by
default 128 comms.

The structure that uses this creates an array to store the pids using
PID_MAX_DEFAULT (which is usually set to 32768). This causes the structure
to be of the size of 131104 bytes on 64 bit machines.

In hex: 131104 = 0x20020, and since the kernel allocates generic memory in
powers of two, the kernel would allocate 0x40000 or 262144 bytes to store
this structure. That leaves 131040 bytes of wasted space.

Worse, the structure points to an allocated array to store the comm names,
which is 16 bytes times the amount of names to save (currently 128), which
is 2048 bytes. Instead of allocating a separate array, make the structure
end with a variable length string and use the extra space for that.

This is similar to a recommendation that Linus had made about eventfs_inode names:

  https://lore.kernel.org/all/20240130190355.11486-5-torvalds@linux-foundation.org/

Instead of allocating a separate string array to hold the saved comms,
have the structure end with: char saved_cmdlines[]; and round up to the
next power of two over sizeof(struct saved_cmdline_buffers) + num_cmdlines * TASK_COMM_LEN
It will use this extra space for the saved_cmdline portion.

Now, instead of saving only 128 comms by default, by using this wasted
space at the end of the structure it can save over 8000 comms and even
saves space by removing the need for allocating the other array.

bc6619c9aa tracing: Have large events show up as '[LINE TOO BIG]' instead of nothing
[ Upstream commit b55b0a0d7c4aa2dac3579aa7e6802d1f57445096 ]

If a large event was added to the ring buffer that is larger than what the
trace_seq can handle, it just drops the output:

8bf79dec73 tracing: Fix blocked reader of snapshot buffer
commit 39a7dc23a1ed0fe81141792a09449d124c5953bd upstream.

If an application blocks on the snapshot or snapshot_raw files, expecting
to be woken up when a snapshot occurs, it will not happen. Or it may
happen with an unexpected result.

That result is that the application will be reading the main buffer
instead of the snapshot buffer. That is because when the snapshot occurs,
the main and snapshot buffers are swapped. But the reader has a descriptor
still pointing to the buffer that it originally connected to.

This is fine for the main buffer readers, as they may be blocked waiting
for a watermark to be hit, and when a snapshot occurs, the data that the
main readers want is now on the snapshot buffer.

But for waiters of the snapshot buffer, they are waiting for an event to
occur that will trigger the snapshot and they can then consume it quickly
to save the snapshot before the next snapshot occurs. But to do this, they
need to read the new snapshot buffer, not the old one that is now
receiving new data.

Also, it does not make sense to have a watermark "buffer_percent" on the
snapshot buffer, as the snapshot buffer is static and does not receive new
data except all at once.

d7a2939814 tracing: Update snapshot buffer on resize if it is allocated
commit d06aff1cb13d2a0d52b48e605462518149c98c81 upstream.

The snapshot buffer is to mimic the main buffer so that when a snapshot is
needed, the snapshot and main buffer are swapped. When the snapshot buffer
is allocated, it is set to the minimal size that the ring buffer may be at
and still functional. When it is allocated it becomes the same size as the
main ring buffer, and when the main ring buffer changes in size, it should
do.

Currently, the resize only updates the snapshot buffer if it's used by the
current tracer (ie. the preemptirqsoff tracer). But it needs to be updated
anytime it is allocated.

When changing the size of the main buffer, instead of looking to see if
the current tracer is utilizing the snapshot buffer, just check if it is
allocated to know if it should be updated or not.

Also fix typo in comment just above the code change.

f460ff26bd tracing: Stop current tracer when resizing buffer
[ Upstream commit d78ab792705c7be1b91243b2544d1a79406a2ad7 ]

When the ring buffer is being resized, it can cause side effects to the
running tracer. For instance, there's a race with irqsoff tracer that
swaps individual per cpu buffers between the main buffer and the snapshot
buffer. The resize operation modifies the main buffer and then the
snapshot buffer. If a swap happens in between those two operations it will
break the tracer.

Simply stop the running tracer before resizing the buffers and enable it
again when finished.

21beb0d86f tracing: Set actual size after ring buffer resize
[ Upstream commit 6d98a0f2ac3c021d21be66fa34e992137cd25bcb ]

Currently we can resize trace ringbuffer by writing a value into file
'buffer_size_kb', then by reading the file, we get the value that is
usually what we wrote. However, this value may be not actual size of
trace ring buffer because of the round up when doing resize in kernel,
and the actual size would be more useful.

0d0564cfb7 tracing: Fix a possible race when disabling buffered events
commit c0591b1cccf708a47bc465c62436d669a4213323 upstream.

Function trace_buffered_event_disable() is responsible for freeing pages
backing buffered events and this process can run concurrently with
trace_event_buffer_lock_reserve().

The following race is currently possible:

* Function trace_buffered_event_disable() is called on CPU 0. It
  increments trace_buffered_event_cnt on each CPU and waits via
  synchronize_rcu() for each user of trace_buffered_event to complete.

* After synchronize_rcu() is finished, function
  trace_buffered_event_disable() has the exclusive access to
  trace_buffered_event. All counters trace_buffered_event_cnt are at 1
  and all pointers trace_buffered_event are still valid.

* At this point, on a different CPU 1, the execution reaches
  trace_event_buffer_lock_reserve(). The function calls
  preempt_disable_notrace() and only now enters an RCU read-side
  critical section. The function proceeds and reads a still valid
  pointer from trace_buffered_event[CPU1] into the local variable
  "entry". However, it doesn't yet read trace_buffered_event_cnt[CPU1]
  which happens later.

* Function trace_buffered_event_disable() continues. It frees
  trace_buffered_event[CPU1] and decrements
  trace_buffered_event_cnt[CPU1] back to 0.

* Function trace_event_buffer_lock_reserve() continues. It reads and
  increments trace_buffered_event_cnt[CPU1] from 0 to 1. This makes it
  believe that it can use the "entry" that it already obtained but the
  pointer is now invalid and any access results in a use-after-free.

Fix the problem by making a second synchronize_rcu() call after all
trace_buffered_event values are set to NULL. This waits on all potential
users in trace_event_buffer_lock_reserve() that still read a previous
pointer from trace_buffered_event.

For instance, it can be triggered by running these two commands in
parallel:

 $ while true; do
    echo hist:key=id.syscall:val=hitcount > \
      /sys/kernel/debug/tracing/events/raw_syscalls/sys_enter/trigger;
  done
 $ stress-ng --sysinfo $(nproc)

The warning indicates that the current ring_buffer_per_cpu is not in the
committing state. It happens because the active ring_buffer_event
doesn't actually come from the ring_buffer_per_cpu but is allocated from
trace_buffered_event.

The bug is in function trace_buffered_event_disable() where the
following normally happens:

* The code invokes disable_trace_buffered_event() via
  smp_call_function_many() and follows it by synchronize_rcu(). This
  increments the per-CPU variable trace_buffered_event_cnt on each
  target CPU and grants trace_buffered_event_disable() the exclusive
  access to the per-CPU variable trace_buffered_event.

* Maintenance is performed on trace_buffered_event, all per-CPU event
  buffers get freed.

* The code invokes enable_trace_buffered_event() via
  smp_call_function_many(). This decrements trace_buffered_event_cnt and
  releases the access to trace_buffered_event.

A problem is that smp_call_function_many() runs a given function on all
target CPUs except on the current one. The following can then occur:

* Task X executing trace_buffered_event_disable() runs on CPU 0.

* The control reaches synchronize_rcu() and the task gets rescheduled on
  another CPU 1.

* The RCU synchronization finishes. At this point,
  trace_buffered_event_disable() has the exclusive access to all
  trace_buffered_event variables except trace_buffered_event[CPU0]
  because trace_buffered_event_cnt[CPU0] is never incremented and if the
  buffer is currently unused, remains set to 0.

* A different task Y is scheduled on CPU 0 and hits a trace event. The
  code in trace_event_buffer_lock_reserve() sees that
  trace_buffered_event_cnt[CPU0] is set to 0 and decides the use the
  buffer provided by trace_buffered_event[CPU0].

* Task X continues its execution in trace_buffered_event_disable(). The
  code incorrectly frees the event buffer pointed by
  trace_buffered_event[CPU0] and resets the variable to NULL.

* Task Y writes event data to the now freed buffer and later detects the
  created inconsistency.

The issue is observable since commit dea499781a11 ("tracing: Fix warning
in trace_buffered_event_disable()") which moved the call of
trace_buffered_event_disable() in __ftrace_event_enable_disable()
earlier, prior to invoking call->class->reg(.. TRACE_REG_UNREGISTER ..).
The underlying problem in trace_buffered_event_disable() is however
present since the original implementation in commit 0fc1b09ff1
("tracing: Use temp buffer when filtering events").

Fix the problem by replacing the two smp_call_function_many() calls with
on_each_cpu_mask() which invokes a given callback on all CPUs.

ad9efb0b27 tracing: Disable snapshot buffer when stopping instance tracers
commit b538bf7d0ec11ca49f536dfda742a5f6db90a798 upstream.

It use to be that only the top level instance had a snapshot buffer (for
latency tracers like wakeup and irqsoff). When stopping a tracer in an
instance would not disable the snapshot buffer. This could have some
unintended consequences if the irqsoff tracer is enabled.

Consolidate the tracing_start/stop() with tracing_start/stop_tr() so that
all instances behave the same. The tracing_start/stop() functions will
just call their respective tracing_start/stop_tr() with the global_array
passed in.

97c2b3b232 tracing: Always update snapshot buffer size
commit 7be76461f302ec05cbd62b90b2a05c64299ca01f upstream.

It use to be that only the top level instance had a snapshot buffer (for
latency tracers like wakeup and irqsoff). The update of the ring buffer
size would check if the instance was the top level and if so, it would
also update the snapshot buffer as it needs to be the same as the main
buffer.

Now that lower level instances also has a snapshot buffer, they too need
to update their snapshot buffer sizes when the main buffer is changed,
otherwise the following can be triggered:

 # cd /sys/kernel/tracing
 # echo 1500 > buffer_size_kb
 # mkdir instances/foo
 # echo irqsoff > instances/foo/current_tracer
 # echo 1000 > instances/foo/buffer_size_kb

Produces:

 WARNING: CPU: 2 PID: 856 at kernel/trace/trace.c:1938 update_max_tr_single.part.0+0x27d/0x320

Which is:

	ret = ring_buffer_swap_cpu(tr->max_buffer.buffer, tr->array_buffer.buffer, cpu);

	if (ret == -EBUSY) {
		[..]
	}

	WARN_ON_ONCE(ret && ret != -EAGAIN && ret != -EBUSY);  <== here

That's because ring_buffer_swap_cpu() has:

	int ret = -EINVAL;

	[..]

	/* At least make sure the two buffers are somewhat the same */
	if (cpu_buffer_a->nr_pages != cpu_buffer_b->nr_pages)
		goto out;

	[..]
 out:
	return ret;
 }

Instead, update all instances' snapshot buffer sizes when their main
buffer size is updated.

a28083d41c tracing: Fix a warning when allocating buffered events fails
[ Upstream commit 34209fe83ef8404353f91ab4ea4035dbc9922d04 ]

Function trace_buffered_event_disable() produces an unexpected warning
when the previous call to trace_buffered_event_enable() fails to
allocate pages for buffered events.

The situation can occur as follows:

* The counter trace_buffered_event_ref is at 0.

* The soft mode gets enabled for some event and
  trace_buffered_event_enable() is called. The function increments
  trace_buffered_event_ref to 1 and starts allocating event pages.

* The allocation fails for some page and trace_buffered_event_disable()
  is called for cleanup.

* Function trace_buffered_event_disable() decrements
  trace_buffered_event_ref back to 0, recognizes that it was the last
  use of buffered events and frees all allocated pages.

* The control goes back to trace_buffered_event_enable() which returns.
  The caller of trace_buffered_event_enable() has no information that
  the function actually failed.

* Some time later, the soft mode is disabled for the same event.
  Function trace_buffered_event_disable() is called. It warns on
  "WARN_ON_ONCE(!trace_buffered_event_ref)" and returns.

Buffered events are just an optimization and can handle failures. Make
trace_buffered_event_enable() exit on the first failure and left any
cleanup later to when trace_buffered_event_disable() is called.

commit bb32500fb9b78215e4ef6ee8b4345c5f5d7eafb4 upstream.

It breaks the current Android ABI, and if needed, can be brought back in
an abi-safe way in the future.

a98172e36e tracing: Have trace_event_file have ref counters
commit bb32500fb9b78215e4ef6ee8b4345c5f5d7eafb4 upstream.

The following can crash the kernel:

 # cd /sys/kernel/tracing
 # echo 'p:sched schedule' > kprobe_events
 # exec 5>>events/kprobes/sched/enable
 # > kprobe_events
 # exec 5>&-

The above commands:

 1. Change directory to the tracefs directory
 2. Create a kprobe event (doesn't matter what one)
 3. Open bash file descriptor 5 on the enable file of the kprobe event
 4. Delete the kprobe event (removes the files too)
 5. Close the bash file descriptor 5

The above causes a crash!

 BUG: kernel NULL pointer dereference, address: 0000000000000028
 #PF: supervisor read access in kernel mode
 #PF: error_code(0x0000) - not-present page
 PGD 0 P4D 0
 Oops: 0000 [#1] PREEMPT SMP PTI
 CPU: 6 PID: 877 Comm: bash Not tainted 6.5.0-rc4-test-00008-g2c6b6b1029d4-dirty #186
 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.2-debian-1.16.2-1 04/01/2014
 RIP: 0010:tracing_release_file_tr+0xc/0x50

What happens here is that the kprobe event creates a trace_event_file
"file" descriptor that represents the file in tracefs to the event. It
maintains state of the event (is it enabled for the given instance?).
Opening the "enable" file gets a reference to the event "file" descriptor
via the open file descriptor. When the kprobe event is deleted, the file is
also deleted from the tracefs system which also frees the event "file"
descriptor.

But as the tracefs file is still opened by user space, it will not be
totally removed until the final dput() is called on it. But this is not
true with the event "file" descriptor that is already freed. If the user
does a write to or simply closes the file descriptor it will reference the
event "file" descriptor that was just freed, causing a use-after-free bug.

To solve this, add a ref count to the event "file" descriptor as well as a
new flag called "FREED". The "file" will not be freed until the last
reference is released. But the FREE flag will be set when the event is
removed to prevent any more modifications to that event from happening,
even if there's still a reference to the event "file" descriptor.

407bf1c140 tracing: Increase trace array ref count on enable and filter files
[ Upstream commit f5ca233e2e66dc1c249bf07eefa37e34a6c9346a ]

When the trace event enable and filter files are opened, increment the
trace array ref counter, otherwise they can be accessed when the trace
array is being deleted. The ref counter keeps the trace array from being
deleted while those files are opened.

db08d2cf82 Revert "tracing: Introduce pipe_cpumask to avoid race on trace_pipes"
This reverts commit 0c0547d2a6 which is
commit c2489bb7e6be2e8cdced12c16c42fa128403ac03 upstream.

It breaks the Android kabi and is not needed for Android systems.  If it
is needed in the future, it can be brought back in an abi-safe way.

b3183f5f05 tracing: Have option files inc the trace array ref count
commit 7e2cfbd2d3c86afcd5c26b5c4b1dd251f63c5838 upstream.

The option files update the options for a given trace array. For an
instance, if the file is opened and the instance is deleted, reading or
writing to the file will cause a use after free.

Up the ref count of the trace_array when an option file is opened.

5103216b86 tracing: Zero the pipe cpumask on alloc to avoid spurious -EBUSY
commit 3d07fa1dd19035eb0b13ae6697efd5caa9033e74 upstream.

The pipe cpumask used to serialize opens between the main and percpu
trace pipes is not zeroed or initialized. This can result in
spurious -EBUSY returns if underlying memory is not fully zeroed.
This has been observed by immediate failure to read the main
trace_pipe file on an otherwise newly booted and idle system:

 # cat /sys/kernel/debug/tracing/trace_pipe
 cat: /sys/kernel/debug/tracing/trace_pipe: Device or resource busy

Zero the allocation of pipe_cpumask to avoid the problem.

It is because the race between writing event into cpu buffer and swapping

  Write on CPU 0             Swap buffer by per_cpu/cpu0/snapshot on CPU 1

          != buffer)) { // 3. This check passed due to 'cpu_buffer->buffer'
        [...]           //    has not changed here.
        return NULL;
      }
                                 cpu_buffer_b->buffer = buffer_a;
                                 cpu_buffer_a->buffer = buffer_b;

    [...]
    cpu_buffer = buffer->buffers[cpu]; // 5. Now find 'cpu_buffer_b' !!!
    rb_commit(cpu_buffer)
      rb_end_commit()  // 6. WARN for the wrong 'committing' state !!!

Based on above analysis, we can easily reproduce by following testcase:
  ``` bash
  #!/bin/bash

  dmesg -n 7
  sysctl -w kernel.panic_on_warn=1
  TR=/sys/kernel/tracing
  echo 7 > ${TR}/buffer_size_kb
  echo "sched:sched_switch" > ${TR}/set_event
  while [ true ]; do
          echo 1 > ${TR}/per_cpu/cpu0/snapshot
  done &
  while [ true ]; do
          echo 1 > ${TR}/per_cpu/cpu0/snapshot
  done &
  while [ true ]; do
          echo 1 > ${TR}/per_cpu/cpu0/snapshot
  done &
  ```

To fix it, IIUC, we can use smp_call_function_single() to do the swap on
the target cpu where the buffer is located, so that above race would be
avoided.

0c0547d2a6 tracing: Introduce pipe_cpumask to avoid race on trace_pipes
[ Upstream commit c2489bb7e6be2e8cdced12c16c42fa128403ac03 ]

There is race issue when concurrently splice_read main trace_pipe and
per_cpu trace_pipes which will result in data read out being different
from what actually writen.

As suggested by Steven:
  > I believe we should add a ref count to trace_pipe and the per_cpu
  > trace_pipes, where if they are opened, nothing else can read it.
  >
  > Opening trace_pipe locks all per_cpu ref counts, if any of them are
  > open, then the trace_pipe open will fail (and releases any ref counts
  > it had taken).
  >
  > Opening a per_cpu trace_pipe will up the ref count for just that
  > CPU buffer. This will allow multiple tasks to read different per_cpu
  > trace_pipe files, but will prevent the main trace_pipe file from
  > being opened.

But because we only need to know whether per_cpu trace_pipe is open or
not, using a cpumask instead of using ref count may be easier.

After this patch, users will find that:
 - Main trace_pipe can be opened by only one user, and if it is
   opened, all per_cpu trace_pipes cannot be opened;
 - Per_cpu trace_pipes can be opened by multiple users, but each per_cpu
   trace_pipe can only be opened by one user. And if one of them is
   opened, main trace_pipe cannot be opened.

      [<000000000c309c35>] el0_sync+0x160/0x180

The root cause is descripted as follows:

  __tracing_open() {  // 1. File 'trace' is being opened;
    ...
    *iter->trace = *tr->current_trace;  // 2. Tracer 'function_graph' is
                                        //    currently set;
    ...
    iter->trace->open(iter);  // 3. Call graph_trace_open() here,
                              //    and memory are allocated in it;
    ...
  }

  s_start() {  // 4. The opened file is being read;
    ...
    *iter->trace = *tr->current_trace;  // 5. If tracer is switched to
                                        //    'nop' or others, then memory
                                        //    in step 3 are leaked!!!
    ...
  }

To fix it, in s_start(), close tracer before switching then reopen the
new tracer after switching. And some tracers like 'wakeup' may not update
'iter->private' in some cases when reopen, then it should be cleared
to avoid being mistakenly closed again.

9c2ceffd4e tracing: Fix cpu buffers unavailable due to 'record_disabled' missed
[ Upstream commit b71645d6af10196c46cbe3732de2ea7d36b3ff6d ]

Trace ring buffer can no longer record anything after executing
following commands at the shell prompt:

  # cd /sys/kernel/tracing
  # cat tracing_cpumask
  fff
  # echo 0 > tracing_cpumask
  # echo 1 > snapshot
  # echo fff > tracing_cpumask
  # echo 1 > tracing_on
  # echo "hello world" > trace_marker
  -bash: echo: write error: Bad file descriptor

The root cause is that:
  1. After `echo 0 > tracing_cpumask`, 'record_disabled' of cpu buffers
     in 'tr->array_buffer.buffer' became 1 (see tracing_set_cpumask());
  2. After `echo 1 > snapshot`, 'tr->array_buffer.buffer' is swapped
     with 'tr->max_buffer.buffer', then the 'record_disabled' became 0
     (see update_max_tr());
  3. After `echo fff > tracing_cpumask`, the 'record_disabled' become -1;
Then array_buffer and max_buffer are both unavailable due to value of
'record_disabled' is not 0.

To fix it, enable or disable both array_buffer and max_buffer at the same
time in tracing_set_cpumask().

It breaks the Android kernel abi, and is not needed for any Android

back in an abi-safe way.

66a3b2a121 ring-buffer: Do not swap cpu_buffer during resize process
[ Upstream commit 8a96c0288d0737ad77882024974c075345c72011 ]

When ring_buffer_swap_cpu was called during resize process,
the cpu buffer was swapped in the middle, resulting in incorrect state.
Continuing to run in the wrong state will result in oops.

This issue can be easily reproduced using the following two scripts:
/tmp # cat test1.sh
//#! /bin/sh
for i in `seq 0 100000`
do
         echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb
         sleep 0.5
         echo 5000 > /sys/kernel/debug/tracing/buffer_size_kb
         sleep 0.5
done
/tmp # cat test2.sh
//#! /bin/sh
for i in `seq 0 100000`
do
        echo irqsoff > /sys/kernel/debug/tracing/current_tracer
        sleep 1
        echo nop > /sys/kernel/debug/tracing/current_tracer
        sleep 1
done
/tmp # ./test1.sh &
/tmp # ./test2.sh &

A typical oops log is as follows, sometimes with other different oops logs.

426656e8dd tracing: Fix sleeping while atomic in kdb ftdump
commit 495fcec8648cdfb483b5b9ab310f3839f07cb3b8 upstream.

If you drop into kdb and type "ftdump" you'll get a sleeping while
atomic warning from memory allocation in trace_find_next_entry().

This appears to have been caused by commit ff895103a8 ("tracing:
Save off entry when peeking at next entry"), which added the
allocation in that path. The problematic commit was already fixed by
commit 8e99cf91b9 ("tracing: Do not allocate buffer in
trace_find_next_entry() in atomic") but that fix missed the kdb case.

The fix here is easy: just move the assignment of the static buffer to
the place where it should have been to begin with:
trace_init_global_iter(). That function is called in two places, once
is right before the assignment of the static buffer added by the
previous fix and once is in kdb.

Note that it appears that there's a second static buffer that we need
to assign that was added in commit efbbdaa22bb7 ("tracing: Show real
address for trace event arguments"), so we'll move that too.

840ce9cfc8 tracing: Show real address for trace event arguments
[ Upstream commit efbbdaa22bb78761bff8dfdde027ad04bedd47ce ]

To help debugging kernel, show real address for trace event arguments
in tracefs/trace{,pipe} instead of hashed pointer value.

Since ftrace human-readable format uses vsprintf(), all %p are
translated to hash values instead of pointer address.

However, when debugging the kernel, raw address value gives a
hint when comparing with the memory mapping in the kernel.
(Those are sometimes used with crash log, which is not hashed too)
So converting %p with %px when calling trace_seq_printf().

Moreover, this is not improving the security because the tracefs
can be used only by root user and the raw address values are readable
from tracefs/percpu/cpu*/trace_pipe_raw file.

7060e5aac6 tracing: Fix null pointer dereference in tracing_err_log_open()
commit 02b0095e2fbbc060560c1065f86a211d91e27b26 upstream.

Fix an issue in function 'tracing_err_log_open'.
The function doesn't call 'seq_open' if the file is opened only with
write permissions, which results in 'file->private_data' being left as null.
If we then use 'lseek' on that opened file, 'seq_lseek' dereferences
'file->private_data' in 'mutex_lock(&m->lock)', resulting in a kernel panic.
Writing to this node requires root privileges, therefore this bug
has very little security impact.

Tracefs node: /sys/kernel/tracing/error_log

Example Kernel panic:

Unable to handle kernel NULL pointer dereference at virtual address 0000000000000038

db4ab0c97a tracing: Add tracing_reset_all_online_cpus_unlocked() function
commit e18eb8783ec4949adebc7d7b0fdb65f65bfeefd9 upstream.

Currently the tracing_reset_all_online_cpus() requires the
trace_types_lock held. But only one caller of this function actually has
that lock held before calling it, and the other just takes the lock so
that it can call it. More users of this function is needed where the lock
is not held.

Add a tracing_reset_all_online_cpus_unlocked() function for the one use
case that calls it without being held, and also add a lockdep_assert to
make sure it is held when called.

Then have tracing_reset_all_online_cpus() take the lock internally, such
that callers do not need to worry about taking it.

6e36373aa5 tracing: Free error logs of tracing instances
commit 3357c6e429643231e60447b52ffbb7ac895aca22 upstream.

When a tracing instance is removed, the error messages that hold errors
that occurred in the instance needs to be freed. The following reports a
memory leak:

 # cd /sys/kernel/tracing
 # mkdir instances/foo
