Pull CXL (Compute Express Link) fixes from Dan Williams:
"A collection of CXL fixes.
The touch outside of drivers/cxl/ is for a helper that allocates
physical address space. Device hotplug tests showed that the driver
failed to utilize (skipped over) valid capacity when allocating a new
memory region. Outside of that, new tests uncovered a small crop of
lockdep reports.
There is also some miscellaneous error path and leak fixups that are
not urgent, but useful to cleanup now.

Tracing fixes for v6.7-rc5:
- Fix eventfs to check creating new files for events with names greater than NAME_MAX. The eventfs lookup needs to check the return result of simple_lookup(). - Fix the ring buffer to check the proper max data size. Events must be able to fit on the ring buffer sub-buffer, if it cannot, then it fails to be written and the logic to add the event is avoided. The code to check if an event can fit failed to add the possible absolute timestamp which may make the event not be able to fit. This causes the ring buffer to go into an infinite loop trying to find a sub-buffer that would fit the event. Luckily, there's a check that will bail out if it looped over a 1000 times and it also warns. The real fix is not to add the absolute timestamp to an event that is starting at the beginning of a sub-buffer because it uses the sub-buffer timestamp. By avoiding the timestamp at the start of the sub-buffer allows events that pass the first check to always find a sub-buffer that it can fit on. - Have large events that do not fit on a trace_seq to print "LINE TOO BIG" like it does for the trace_pipe instead of what it does now which is to silently drop the output. - Fix a memory leak of forgetting to free the spare page that is saved by a trace instance. - Update the size of the snapshot buffer when the main buffer is updated if the snapshot buffer is allocated. - Fix ring buffer timestamp logic by removing all the places that tried to put the before_stamp back to the write stamp so that the next event doesn't add an absolute timestamp. But each of these updates added a race where by making the two timestamp equal, it was validating the write_stamp so that it can be incorrectly used for calculating the delta of an event. - There's a temp buffer used for printing the event that was using the event data size for allocation when it needed to use the size of the entire event (meta-data and payload data) - For hardening, use "%.*s" for printing the trace_marker output, to limit the amount that is printed by the size of the event. This was discovered by development that added a bug that truncated the '\0' and caused a crash. - Fix a use-after-free bug in the use of the histogram files when an instance is being removed. - Remove a useless update in the rb_try_to_discard of the write_stamp. The before_stamp was already changed to force the next event to add an absolute timestamp that the write_stamp is not used. But the write_stamp is modified again using an unneeded 64-bit cmpxchg. - Fix several races in the 32-bit implementation of the rb_time_cmpxchg() that does a 64-bit cmpxchg. - While looking at fixing the 64-bit cmpxchg, I noticed that because the ring buffer uses normal cmpxchg, and this can be done in NMI context, there's some architectures that do not have a working cmpxchg in NMI context. For these architectures, fail recording events that happen in NMI context. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZX0nChQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qlOMAQD3iegTcceQl9lAsroa3tb3xdweC1GP 51MsX5athxSyoQEAutI/2pBCtLFXgTLMHAMd5F23EM1U9rha7W0myrnvKQY= =d3bS -----END PGP SIGNATURE----- Merge tag 'trace-v6.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix eventfs to check creating new files for events with names greater than NAME_MAX.

cred: switch to using atomic_long_t
There are multiple ways to grab references to credentials, and the only protection we have against overflowing it is the memory required to do so. With memory sizes only moving in one direction, let's bump the reference count to 64-bit and move it outside the realm of feasibly overflowing.

ring-buffer: Have rb_time_cmpxchg() set the msb counter too
The rb_time_cmpxchg() on 32-bit architectures requires setting three
32-bit words to represent the 64-bit timestamp, with some salt for
synchronization. Those are: msb, top, and bottom
The issue is, the rb_time_cmpxchg() did not properly salt the msb portion,
and the msb that was written was stale.

ring-buffer: Fix 32-bit rb_time_read() race with rb_time_cmpxchg()
The following race can cause rb_time_read() to observe a corrupted time
stamp:
rb_time_cmpxchg()
[...]
if (!rb_time_read_cmpxchg(&t->msb, msb, msb2))
return false;
if (!rb_time_read_cmpxchg(&t->top, top, top2))
return false;
<interrupted before updating bottom>
__rb_time_read()
[...]
do {
c = local_read(&t->cnt);
top = local_read(&t->top);
bottom = local_read(&t->bottom);
msb = local_read(&t->msb);
} while (c != local_read(&t->cnt));
*cnt = rb_time_cnt(top);
/* If top and msb counts don't match, this interrupted a write */
if (*cnt != rb_time_cnt(msb))
return false;
^ this check fails to catch that "bottom" is still not updated.
So the old "bottom" value is returned, which is wrong.
Fix this by checking that all three of msb, top, and bottom 2-bit cnt
values match.
The reason to favor checking all three fields over requiring a specific
update order for both rb_time_set() and rb_time_cmpxchg() is because
checking all three fields is more robust to handle partial failures of
rb_time_cmpxchg() when interrupted by nested rb_time_set().

ring-buffer: Fix a race in rb_time_cmpxchg() for 32 bit archs
Mathieu Desnoyers pointed out an issue in the rb_time_cmpxchg() for 32 bit
architectures. That is:
static bool rb_time_cmpxchg(rb_time_t *t, u64 expect, u64 set)
{
unsigned long cnt, top, bottom, msb;
unsigned long cnt2, top2, bottom2, msb2;
u64 val;
/* The cmpxchg always fails if it interrupted an update */
if (!__rb_time_read(t, &val, &cnt2))
return false;
if (val != expect)
return false;
<<<< interrupted here!
cnt = local_read(&t->cnt);
The problem is that the synchronization counter in the rb_time_t is read
*after* the value of the timestamp is read. That means if an interrupt
were to come in between the value being read and the counter being read,
it can change the value and the counter and the interrupted process would
be clueless about it!
The counter needs to be read first and then the value. That way it is easy
to tell if the value is stale or not. If the counter hasn't been updated,
then the value is still good.

ring-buffer: Remove useless update to write_stamp in rb_try_to_discard()
When filtering is enabled, a temporary buffer is created to place the
content of the trace event output so that the filter logic can decide
from the trace event output if the trace event should be filtered out or
not. If it is to be filtered out, the content in the temporary buffer is
simply discarded, otherwise it is written into the trace buffer.
But if an interrupt were to come in while a previous event was using that
temporary buffer, the event written by the interrupt would actually go
into the ring buffer itself to prevent corrupting the data on the
temporary buffer. If the event is to be filtered out, the event in the
ring buffer is discarded, or if it fails to discard because another event
were to have already come in, it is turned into padding.
The update to the write_stamp in the rb_try_to_discard() happens after a
fix was made to force the next event after the discard to use an absolute
timestamp by setting the before_stamp to zero so it does not match the
write_stamp (which causes an event to use the absolute timestamp).
But there's an effort in rb_try_to_discard() to put back the write_stamp
to what it was before the event was added. But this is useless and
wasteful because nothing is going to be using that write_stamp for
calculations as it still will not match the before_stamp.
Remove this useless update, and in doing so, we remove another
cmpxchg64()!
Also update the comments to reflect this change as well as remove some
extra white space in another comment.

ring-buffer: Do not try to put back write_stamp
If an update to an event is interrupted by another event between the time
the initial event allocated its buffer and where it wrote to the
write_stamp, the code try to reset the write stamp back to the what it had
just overwritten. It knows that it was overwritten via checking the
before_stamp, and if it didn't match what it wrote to the before_stamp
before it allocated its space, it knows it was overwritten.
To put back the write_stamp, it uses the before_stamp it read. The problem
here is that by writing the before_stamp to the write_stamp it makes the
two equal again, which means that the write_stamp can be considered valid
as the last timestamp written to the ring buffer. But this is not
necessarily true. The event that interrupted the event could have been
interrupted in a way that it was interrupted as well, and can end up
leaving with an invalid write_stamp. But if this happens and returns to
this context that uses the before_stamp to update the write_stamp again,
it can possibly incorrectly make it valid, causing later events to have in
correct time stamps.
As it is OK to leave this function with an invalid write_stamp (one that
doesn't match the before_stamp), there's no reason to try to make it valid
again in this case. If this race happens, then just leave with the invalid
write_stamp and the next event to come along will just add a absolute
timestamp and validate everything again.
Bonus points: This gets rid of another cmpxchg64!

devm_cxl_pmu_add() correctly registers a device remove function but it

Properly call device_unregister() to free up the memory associated with

drm/nouveau/kms/nv50-: Don't allow inheritance of headless iors
Turns out we made a silly mistake when coming up with OR inheritance on nouveau. On pre-DCB 4.1, iors are statically routed to output paths via the DCB. On later generations iors are only routed to an output path if they're actually being used. Unfortunately, it appears with NVIF_OUTP_INHERIT_V0 we make the mistake of assuming the later is true on all generations, which is currently leading us to return bogus ior -> head assignments through nvif, which causes WARN_ON(). So - fix this by verifying that we actually know that there's a head assigned to an ior before allowing it to be inherited through nvif. This -should- hopefully fix the WARN_ON on GT218 reported by Borislav.

net: atlantic: fix double free in ring reinit logic
Driver has a logic leak in ring data allocation/free,
where double free may happen in aq_ring_free if system is under
stress and driver init/deinit is happening.
The probability is higher to get this during suspend/resume cycle.
Verification was done simulating same conditions with
stress -m 2000 --vm-bytes 20M --vm-hang 10 --backoff 1000
while true; do sudo ifconfig enp1s0 down; sudo ifconfig enp1s0 up; done
Fixed by explicitly clearing pointers to NULL on deallocation

ALSA: hda/tas2781: reset the amp before component_add
Calling component_add starts loading the firmware, the callback function
writes the program to the amplifiers. If the module resets the
amplifiers after component_add, it happens that one of the amplifiers
does not work because the reset and program writing are interleaving.
Call tas2781_reset before component_add to ensure reliable
initialization.

appletalk: Fix Use-After-Free in atalk_ioctl
Because atalk_ioctl() accesses sk->sk_receive_queue
without holding a sk->sk_receive_queue.lock, it can
cause a race with atalk_recvmsg().
A use-after-free for skb occurs with the following flow.
```
atalk_ioctl() -> skb_peek()
atalk_recvmsg() -> skb_recv_datagram() -> skb_free_datagram()
```
Add sk->sk_receive_queue.lock to atalk_ioctl() to fix this issue.

tracing: Fix uaf issue when open the hist or hist_debug file
KASAN report following issue. The root cause is when opening 'hist'
file of an instance and accessing 'trace_event_file' in hist_show(),
but 'trace_event_file' has been freed due to the instance being removed.
'hist_debug' file has the same problem. To fix it, call
tracing_{open,release}_file_tr() in file_operations callback to have
the ref count and avoid 'trace_event_file' being freed.

net: prevent mss overflow in skb_segment()
Once again syzbot is able to crash the kernel in skb_segment() [1]
GSO_BY_FRAGS is a forbidden value, but unfortunately the following
computation in skb_segment() can reach it quite easily :
mss = mss * partial_segs;
65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to
a bad final result.
Make sure to limit segmentation so that the new mss value is smaller

drm/amdgpu: fix tear down order in amdgpu_vm_pt_free
When freeing PD/PT with shadows it can happen that the shadow destruction races with detaching the PD/PT from the VM causing a NULL pointer dereference in the invalidation code. Fix this by detaching the the PD/PT from the VM first and then freeing the shadow instead.
