7fdbc5f014 io_uring: disallow self-propelled ring polling
When we post a CQE we wake all ring pollers as it normally should be.
However, if a CQE was generated by a multishot poll request targeting
its own ring, it'll wake that request up, which will make it to post
a new CQE, which will wake the request and so on until it exhausts all
CQ entries.

Don't allow multishot polling io_uring files but downgrade them to
oneshots, which was always stated as a correct behaviour that the
userspace should check for.

984bf2cc53 dm integrity: clear the journal on suspend
There was a problem that a user burned a dm-integrity image on CDROM
and could not activate it because it had a non-empty journal.

Fix this problem by flushing the journal (done by the previous commit)
and clearing the journal (done by this commit). Once the journal is
cleared, dm-integrity won't attempt to replay it on the next
activation.

This commit flushes the journal on suspend. It is prerequisite for the
next commit that enables activating dm integrity devices in read-only mode.

Note that we deliberately didn't flush the journal on suspend, so that the
journal replay code would be tested. However, the dm-integrity code is 5
years old now, so that journal replay is well-tested, and we can make this
change now.

f645cbda12 drm/i915/tgl+: Enable display DC power states on all eDP ports
Starting with TGL eDP is supported on ports B+ (besides port A), so make
sure DC states are not blocked on any such ports. For this add an
AUX_IO_<port> power domain for each port with eDP support. These domains
similarly to AUX_IO_A enable only the AUX_IO_<port> power well for an
enabled port, whereas the existing AUX_<port> domains enable both the
AUX_IO_<port> and the DC_OFF power wells as required by DP AUX transfers.

v2: (Ville)
- Split the change using AUX vs. AUX_IO on port A to a separate patch.
- Select AUX_IO vs. AUX based on crtc_state->has_psr instead of
  is_edp().
v3:

v4:

b2e00dd378 drm/i915: Use the AUX_IO power domain only for eDP/PSR port
Use the AUX_IO_A display power domain only for eDP on port A where PSR
is also supported. This is the case where DC states need to be enabled
while the output is enabled - ensured by AUX_IO_A domain not enabling
the DC_OFF power well. Otherwise port A can be treated the same way as
other ports with an external DP output: using the AUX_<port> domain
which disables the unrequired DC states.

This change prepares for the next patch enabling DC states on all ports
supporting eDP/PSR besides port A.

v2:
- Check the encoder PSR capability instead of PSR being enabled in the
  crtc_state, as the latter can be changed with a fastset.

7ed310025e drm/i915: Preallocate the debug power domain wakerefs array
Since the current size of intel_display_power_domain_set struct is
close to 1kB, it's better to use preallocated memory for it. The only
user of the intel_display_power_get/put_in_set() allocating the struct
on stack is hsw_get_pipe_config(), so we can avoid potential stack
overallocations by moving the struct here to the preallocated
intel_crtc struct (hsw_get_pipe_config() is non-reentrant wrt. each
CRTC).

4fe1ec9954 dm ioctl: fix misbehavior if list_versions races with module loading
__list_versions will first estimate the required space using the
"dm_target_iterate(list_version_get_needed, &needed)" call and then will
fill the space using the "dm_target_iterate(list_version_get_info,
&iter_info)" call. Each of these calls locks the targets using the
"down_read(&_lock)" and "up_read(&_lock)" calls, however between the first
and second "dm_target_iterate" there is no lock held and the target
modules can be loaded at this point, so the second "dm_target_iterate"
call may need more space than what was the first "dm_target_iterate"
returned.

The code tries to handle this overflow (see the beginning of
list_version_get_info), however this handling is incorrect.

The code sets "param->data_size = param->data_start + needed" and
"iter_info.end = (char *)vers+len" - "needed" is the size returned by the
first dm_target_iterate call; "len" is the size of the buffer allocated by
userspace.

"len" may be greater than "needed"; in this case, the code will write up
to "len" bytes into the buffer, however param->data_size is set to
"needed", so it may write data past the param->data_size value. The ioctl
interface copies only up to param->data_size into userspace, thus part of
the result will be truncated.

Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this
guarantees that the second "dm_target_iterate" call will write only up to
the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it
overflows the "needed" space - in this case, userspace will allocate a
larger buffer and retry.

Note that there is also a bug in list_version_get_needed - we need to add
"strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".

7ae2e68485 udmabuf: add vmap and vunmap methods to udmabuf_ops
The reason behind that patch is associated with videobuf2 subsystem
(or more genrally with v4l2 framework) and user created
dma buffers (udmabuf). In some circumstances
when dealing with V4L2_MEMORY_DMABUF buffers videobuf2 subsystem
wants to use dma_buf_vmap() method on the attached dma buffer.
As udmabuf does not have .vmap operation implemented,
such dma_buf_vmap() natually fails.

videobuf2_common: __vb2_queue_alloc: allocated 3 buffers, 1 plane(s) each
videobuf2_common: __prepare_dmabuf: buffer for plane 0 changed
videobuf2_common: __prepare_dmabuf: failed to map dmabuf for plane 0
videobuf2_common: __buf_prepare: buffer preparation failed: -14

The patch itself seems to be strighforward.
It adds implementation of .vmap and .vunmap methods
to 'struct dma_buf_ops udmabuf_ops'.
.vmap method itself uses vm_map_ram() to map pages linearly
into the kernel virtual address space.
.vunmap removes mapping created earlier by .vmap.
All locking and 'vmapping counting' is done in dma_buf.c
so it seems to be redundant/unnecessary in .vmap/.vunmap.

c2418f911a gpu: host1x: Avoid trying to use GART on Tegra20
Since commit c7e3ca515e78 ("iommu/tegra: gart: Do not register with
bus") quite some time ago, the GART driver has effectively disabled
itself to avoid issues with the GPU driver expecting it to work in ways
that it doesn't. As of commit 57365a04c921 ("iommu: Move bus setup to
IOMMU device registration") that bodge no longer works, but really the
GPU driver should be responsible for its own behaviour anyway. Make the
workaround explicit.

067df9e0ad tracing: Fix potential null-pointer-access of entry in list 'tr->err_log'
Entries in list 'tr->err_log' will be reused after entry number
exceed TRACING_LOG_ERRS_MAX.

The cmd string of the to be reused entry will be freed first then
allocated a new one. If the allocation failed, then the entry will
still be in list 'tr->err_log' but its 'cmd' field is set to be NULL,
later access of 'cmd' is risky.

Currently above problem can cause the loss of 'cmd' information of first
entry in 'tr->err_log'. When execute `cat /sys/kernel/tracing/error_log`,
reproduce logs like:
  [   37.495100] trace_kprobe: error: Maxactive is not for kprobe(null) ^
  [   38.412517] trace_kprobe: error: Maxactive is not for kprobe

40adaf51cb tracing/eprobe: Fix eprobe filter to make a filter correctly
Since the eprobe filter was defined based on the eprobe's trace event
itself, it doesn't work correctly. Use the original trace event of
the eprobe when making the filter so that the filter works correctly.

Without this fix:

 # echo 1 > events/eprobes/sys_enter_openat/enable

5dd7caf0bd kprobes: Skip clearing aggrprobe's post_handler in kprobe-on-ftrace case
In __unregister_kprobe_top(), if the currently unregistered probe has
post_handler but other child probes of the aggrprobe do not have
post_handler, the post_handler of the aggrprobe is cleared. If this is
a ftrace-based probe, there is a problem. In later calls to
disarm_kprobe(), we will use kprobe_ftrace_ops because post_handler is
NULL. But we're armed with kprobe_ipmodify_ops. This triggers a WARN in
__disarm_kprobe_ftrace() and may even cause use-after-free:

  Failed to disarm kprobe-ftrace at kernel_clone+0x0/0x3c0 (error -2)

For the kprobe-on-ftrace case, we keep the post_handler setting to

can disarm it correctly.

Additionally, in __trace_eprobe_create() function, if an error occurs after
the call to trace_eprobe_parse_filter(), which allocates the filter string,
then memory is also leaked. That can be reproduced by creating the same
event probe twice:

22ea4ca963 tracing: kprobe: Fix potential null-ptr-deref on trace_array in kprobe_event_gen_test_exit()
When test_gen_kprobe_cmd() failed after kprobe_event_gen_cmd_end(), it
will goto delete, which will call kprobe_event_delete() and release the
corresponding resource. However, the trace_array in gen_kretprobe_test
will point to the invalid resource. Set gen_kretprobe_test to NULL
after called kprobe_event_delete() to prevent null-ptr-deref.

1b5f1c34d3 tracing: Fix wild-memory-access in register_synth_event()
In register_synth_event(), if set_synth_event_print_fmt() failed, then
both trace_remove_event_call() and unregister_trace_event() will be
called, which means the trace_event_call will call
__unregister_trace_event() twice. As the result, the second unregister
will causes the wild-memory-access.

register_synth_event
    set_synth_event_print_fmt failed
    trace_remove_event_call
        event_remove
            if call->event.funcs then
            __unregister_trace_event (first call)
    unregister_trace_event
        __unregister_trace_event (second call)

Fix the bug by avoiding to call the second __unregister_trace_event() by
checking if the first one is called.
