Pull tracing fixes from Steven Rostedt:

 - Snapshot buffer issues:

   1. When instances started allowing latency tracers, it uses a
      snapshot buffer (another buffer that is not written to but swapped
      with the main buffer that is). The snapshot buffer needs to be the
      same size as the main buffer. But when the snapshot buffers were
      added to instances, the code to make the snapshot equal to the
      main buffer still was only doing it for the main buffer and not
      the instances.

   2. Need to stop the current tracer when resizing the buffers.
      Otherwise there can be a race if the tracer decides to make a
      snapshot between resizing the main buffer and the snapshot buffer.

   3. When a tracer is "stopped" in disables both the main buffer and
      the snapshot buffer. This needs to be done for instances and not
      only the main buffer, now that instances also have a snapshot
      buffer.

 - Buffered event for filtering issues:

   When filtering is enabled, because events can be dropped often, it is
   quicker to copy the event into a temp buffer and write that into the
   main buffer if it is not filtered or just drop the event if it is,
   than to write the event into the ring buffer and then try to discard
   it. This temp buffer is allocated and needs special synchronization
   to do so. But there were some issues with that:

   1. When disabling the filter and freeing the buffer, a call to all
      CPUs is required to stop each per_cpu usage. But the code called
      smp_call_function_many() which does not include the current CPU.
      If the task is migrated to another CPU when it enables the CPUs
      via smp_call_function_many(), it will not enable the one it is
      currently on and this causes issues later on. Use
      on_each_cpu_mask() instead, which includes the current CPU.

    2.When the allocation of the buffered event fails, it can give a
      warning. But the buffered event is just an optimization (it's
      still OK to write to the ring buffer and free it). Do not WARN in
      this case.

    3.The freeing of the buffer event requires synchronization. First a
      counter is decremented to zero so that no new uses of it will
      happen. Then it sets the buffered event to NULL, and finally it
      frees the buffered event. There's a synchronize_rcu() between the
      counter decrement and the setting the variable to NULL, but only a
      smp_wmb() between that and the freeing of the buffer. It is
      theoretically possible that a user missed seeing the decrement,
      but will use the buffer after it is free. Another
      synchronize_rcu() is needed in place of that smp_wmb().

 - ring buffer timestamps on 32 bit machines

   The ring buffer timestamp on 32 bit machines has to break the 64 bit
   number into multiple values as cmpxchg is required on it, and a 64
   bit cmpxchg on 32 bit architectures is very slow. The code use to
   just use two 32 bit values and make it a 60 bit timestamp where the
   other 4 bits were used as counters for synchronization. It later came
   known that the timestamp on 32 bit still need all 64 bits in some
   cases. So 3 words were created to handle the 64 bits. But issues
   arised with this:

    1. The synchronization logic still only compared the counter with
       the first two, but not with the third number, so the
       synchronization could fail unknowingly.

    2. A check on discard of an event could race if an event happened
       between the discard and updating one of the counters. The counter
       needs to be updated (forcing an absolute timestamp and not to use
       a delta) before the actual discard happens.

If a pointer to an uninitialized struct acpi_handle_list is passed to
acpi_evaluate_reference() and it decides to bail out early, either
because acpi_evaluate_object() fails, or because it produces invalid
data, the handles pointer from the struct acpi_handle_list will be
passed to kfree() and if it is not NULL, the kernel will crash on an
attempt to free unallocated memory.

Address this by moving the "end" label in acpi_evaluate_reference() to
the end of the function, which is sufficient, because no cleanup is
needed in that case.

We could solve it by using min_t(), but this operation seems entirely
unnecessary, because we also pass MAX_SKB_FRAGS to iov_iter_npages(),
which performs almost the same check, returning at most MAX_SKB_FRAGS
elements. So, let's eliminate this unnecessary comparison.

====================
Generic netlink multicast fixes

Restrict two generic netlink multicast groups - in the "psample" and
"NET_DM" families - to be root-only with the appropriate capabilities.
See individual patches for more details.
====================

Link: https://lore.kernel.org/r/20231206213102.1824398-1-idosch@nvidia.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

The "NET_DM" generic netlink family notifies drop locations over the
"events" multicast group. This is problematic since by default generic
netlink allows non-root users to listen to these notifications.

Fix by adding a new field to the generic netlink multicast group
structure that when set prevents non-root users or root without the
'CAP_SYS_ADMIN' capability (in the user namespace owning the network
namespace) from joining the group. Set this field for the "events"
group. Use 'CAP_SYS_ADMIN' rather than 'CAP_NET_ADMIN' because of the
nature of the information that is shared over this group.

Note that the capability check in this case will always be performed
against the initial user namespace since the family is not netns aware
and only operates in the initial network namespace.

A new field is added to the structure rather than using the "flags"
field because the existing field uses uAPI flags and it is inappropriate
to add a new uAPI flag for an internal kernel check. In net-next we can
rework the "flags" field to use internal flags and fold the new field
into it. But for now, in order to reduce the amount of changes, add a
new field.

Since the information can only be consumed by root, mark the control
plane operations that start and stop the tracing as root-only using the
'GENL_ADMIN_PERM' flag.

32-bit emulation was disabled on TDX to prevent a possible attack by
a VMM injecting an interrupt on vector 0x80.

Now that int80_emulation() has a check for external interrupts the
limitation can be lifted.

To distinguish software interrupts from external ones, int80_emulation()
checks the APIC ISR bit relevant to the 0x80 vector. For
software interrupts, this bit will be 0.

On TDX, the VAPIC state (including ISR) is protected and cannot be
manipulated by the VMM. The ISR bit is set by the microcode flow during
the handling of posted interrupts.

There is no real reason to have a separate ASM entry point implementation
for the legacy INT 0x80 syscall emulation on 64-bit.

IDTENTRY provides all the functionality needed with the only difference
that it does not:

  - save the syscall number (AX) into pt_regs::orig_ax
  - set pt_regs::ax to -ENOSYS

Both can be done safely in the C code of an IDTENTRY before invoking any of
the syscall related functions which depend on this convention.

Aside of ASM code reduction this prepares for detecting and handling a
local APIC injected vector 0x80.

kernel expects to receive a software interrupt as a result of the INT
0x80 instruction. However, an external interrupt on the same vector
triggers the same handler.

The kernel interprets an external interrupt on vector 0x80 as a 32-bit
system call that came from userspace.

A VMM can inject external interrupts on any arbitrary vector at any
time.  This remains true even for TDX and SEV guests where the VMM is
untrusted.

Put together, this allows an untrusted VMM to trigger int80 syscall
handling at any given point. The content of the guest register file at
that moment defines what syscall is triggered and its arguments. It
opens the guest OS to manipulation from the VMM side.

Disable 32-bit emulation by default for TDX and SEV. User can override
it with the ia32_emulation=y command line option.
