2cf4f94d8e SCSI fixes on 20231218
Two medium sized fixes, both in drivers.  The UFS one adds parsing of
 clock info structures, which is required by some host drivers and the
 aacraid one reverts the IRQ affinity mapping patch which has been
 causing regressions noted in kernel bugzilla 217599.

26d6084791 spi: Fixes for v6.7
A few bigger things here, the main one being that there were changes to
 the atmel driver in this cycle which made it possible to kill transfers
 being used for filesystem I/O which turned out to be very disruptive,
 the series of patches here undoes that and hardens things up further.
 
 There's also a few smaller driver specific changes, the main one being
 to revert a change that duplicted delays.

 "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.

3b8a9b2e68 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.

a8892fd719 btrfs: do not allow non subvolume root targets for snapshot
Our btrfs subvolume snapshot <source> <destination> utility enforces
that <source> is the root of the subvolume, however this isn't enforced
in the kernel.  Update the kernel to also enforce this limitation to
avoid problems with other users of this ioctl that don't have the
appropriate checks in place.

5df12742b7 Revert "PCI: acpiphp: Reassign resources on bridge if necessary"
This reverts commit 40613da52b and the
subsequent fix to it:

  cc22522fd5 ("PCI: acpiphp: Use pci_assign_unassigned_bridge_resources() only for non-root bus")

40613da52b fixed a problem where hot-adding a device with large BARs
failed if the bridge windows programmed by firmware were not large enough.

cc22522fd5 ("PCI: acpiphp: Use pci_assign_unassigned_bridge_resources()
only for non-root bus") fixed a problem with 40613da52b: an ACPI hot-add
of a device on a PCI root bus (common in the virt world) or firmware
sending ACPI Bus Check to non-existent Root Ports (e.g., on Dell Inspiron
7352/0W6WV0) caused a NULL pointer dereference and suspend/resume hangs.

Unfortunately the combination of 40613da52b and cc22522fd5 caused other
problems:

  - Fiona reported that hot-add of SCSI disks in QEMU virtual machine fails
    sometimes.

  - Dongli reported a similar problem with hot-add of SCSI disks.

  - Jonathan reported a console freeze during boot on bare metal due to an
    error in radeon GPU initialization.

Revert both patches to avoid adding these problems.  This means we will
again see the problems with hot-adding devices with large BARs and the NULL
pointer dereferences and suspend/resume issues that 40613da52b and
cc22522fd5 were intended to fix.

0aa0e5289c 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.

dec890089b 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().

fff88fa0fb 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.

083e9f65bd 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.

dd93942570 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!

7e2c1e4b34 perf: Fix perf_event_validate_size() lockdep splat
When lockdep is enabled, the for_each_sibling_event(sibling, event)
macro checks that event->ctx->mutex is held. When creating a new group
leader event, we call perf_event_validate_size() on a partially
initialized event where event->ctx is NULL, and so when
for_each_sibling_event() attempts to check event->ctx->mutex, we get a
splat, as reported by Lucas De Marchi:

  WARNING: CPU: 8 PID: 1471 at kernel/events/core.c:1950 __do_sys_perf_event_open+0xf37/0x1080

This only happens for a new event which is its own group_leader, and in
this case there cannot be any sibling events. Thus it's safe to skip the
check for siblings, which avoids having to make invasive and ugly
changes to for_each_sibling_event().

Avoid the splat by bailing out early when the new event is its own
group_leader.

7ba84cbf18 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.

46dec61643 drm/nouveau: Fixup gk20a instobj hierarchy
Commit 12c9b05da9 ("drm/nouveau/imem: support allocations not
preserved across suspend") uses container_of() to cast from struct
nvkm_memory to struct nvkm_instobj, assuming that all instance objects
are derived from struct nvkm_instobj. For the gk20a family that's not
the case and they are derived from struct nvkm_memory instead. This
causes some subtle data corruption (nvkm_instobj.preserve ends up
mapping to gk20a_instobj.vaddr) that causes a NULL pointer dereference
in gk20a_instobj_acquire_iommu() (and possibly elsewhere) and also
prevents suspend/resume from working.

Fix this by making struct gk20a_instobj derive from struct nvkm_instobj
instead.

1ba0e9d69b io_uring/cmd: fix breakage in SOCKET_URING_OP_SIOC* implementation
In 8e9fad0e70 "io_uring: Add io_uring command support for sockets"
you've got an include of asm-generic/ioctls.h done in io_uring/uring_cmd.c.
That had been done for the sake of this chunk -
+               ret = prot->ioctl(sk, SIOCINQ, &arg);
+               if (ret)
+                       return ret;
+               return arg;
+       case SOCKET_URING_OP_SIOCOUTQ:
+               ret = prot->ioctl(sk, SIOCOUTQ, &arg);

SIOC{IN,OUT}Q are defined to symbols (FIONREAD and TIOCOUTQ) that come from
ioctls.h, all right, but the values vary by the architecture.

FIONREAD is
	0x467F on mips
	0x4004667F on alpha, powerpc and sparc
	0x8004667F on sh and xtensa
	0x541B everywhere else
TIOCOUTQ is
	0x7472 on mips
	0x40047473 on alpha, powerpc and sparc
	0x80047473 on sh and xtensa
	0x5411 everywhere else

->ioctl() expects the same values it would've gotten from userland; all
places where we compare with SIOC{IN,OUT}Q are using asm/ioctls.h, so
they pick the correct values.  io_uring_cmd_sock(), OTOH, ends up
passing the default ones.

a61f89bf76 perf top: Uniform the event name for the hybrid machine
It's hard to distinguish the default cycles events among hybrid PMUs.
For example,

  $ perf top
  Available samples
  385 cycles:P
  903 cycles:P

The other tool, e.g., perf record, uniforms the event name and adds the
hybrid PMU name before opening the event. So the events can be easily
distinguished. Apply the same methodology for the perf top as well.

The evlist__uniquify_name() will be invoked by both record and top.
Move it to util/evlist.c

With the patch:

  $ perf top
  Available samples
  148 cpu_atom/cycles:P/
  1K cpu_core/cycles:P/

5fa695e7da perf top: Use evsel's cpus to replace user_requested_cpus
perf top errors out on a hybrid machine
 $perf top

 Error:
 The cycles:P event is not supported.

The perf top expects that the "cycles" is collected on all CPUs in the
system. But for hybrid there is no single "cycles" event which can cover
all CPUs. Perf has to split it into two cycles events, e.g.,
cpu_core/cycles/ and cpu_atom/cycles/. Each event has its own CPU mask.
If a event is opened on the unsupported CPU. The open fails. That's the
reason of the above error out.

Perf should only open the cycles event on the corresponding CPU. The
commit ef91871c96 ("perf evlist: Propagate user CPU maps intersecting
core PMU maps") intersect the requested CPU map with the CPU map of the
PMU. Use the evsel's cpus to replace user_requested_cpus.

The evlist's threads are also propagated to the evsel's threads in
__perf_evlist__propagate_maps(). For a system-wide event, perf appends
a dummy event and assign it to the evsel's threads. For a per-thread
event, the evlist's thread_map is assigned to the evsel's threads. The
same as the other tools, e.g., perf record, using the evsel's threads
when opening an event.

4fb54994b2 perf unwind-libunwind: Fix base address for .eh_frame
The base address of a DSO mapping should start at the start of the file.
Usually DSOs are mapped from the pgoff 0 so it doesn't matter when it
uses the start of the map address.

But generated DSOs for JIT codes doesn't start from the 0 so it should
subtract the offset to calculate the .eh_frame table offsets correctly.

c966d23a35 perf unwind-libdw: Handle JIT-generated DSOs properly
Usually DSOs are mapped from the beginning of the file, so the base
address of the DSO can be calculated by map->start - map->pgoff.

However, JIT DSOs which are generated by `perf inject -j`, are mapped
only the code segment.  This makes unwind-libdw code confusing and
rejects processing unwinds in the JIT DSOs.  It should use the map
start address as base for them to fix the confusion.

Pull btrfs fixes from David Sterba:
  "Some fixes to quota accounting code, mostly around error handling and
   correctness:

   - free reserves on various error paths, after IO errors or
     transaction abort

   - don't clear reserved range at the folio release time, it'll be
     properly cleared after final write

   - fix integer overflow due to int used when passing around size of
     freed reservations

   - fix a regression in squota accounting that missed some cases with
     delayed refs"

7bb26ea74a 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

315deab289 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.
