86f6a5cc28 coresight: etm4x: Fix width of CCITMIN field
commit cc0271a339cc70cae914c3ec20edc2a8058407da upstream.

CCITMIN is a 12 bit field and doesn't fit in a u8, so extend it to u16.
This probably wasn't an issue previously because values higher than 255
never occurred.

But since commit 4aff040bcc8d ("coresight: etm: Override TRCIDR3.CCITMIN
on errata affected cpus"), a comparison with 256 was done to enable the
errata, generating the following W=1 build error:

  coresight-etm4x-core.c:1188:24: error: result of comparison of
  constant 256 with expression of type 'u8' (aka 'unsigned char') is
  always false [-Werror,-Wtautological-constant-out-of-range-compare]

   if (drvdata->ccitmin == 256)

2d62412f2f uio: Fix use-after-free in uio_open
commit 0c9ae0b8605078eafc3bea053cc78791e97ba2e2 upstream.

core-1				core-2
-------------------------------------------------------
uio_unregister_device		uio_open
				idev = idr_find()
device_unregister(&idev->dev)
put_device(&idev->dev)
uio_device_release
				get_device(&idev->dev)
kfree(idev)
uio_free_minor(minor)
				uio_release
				put_device(&idev->dev)
				kfree(idev)
-------------------------------------------------------

In the core-1 uio_unregister_device(), the device_unregister will kfree
idev when the idev->dev kobject ref is 1. But after core-1
device_unregister, put_device and before doing kfree, the core-2 may
get_device. Then:
1. After core-1 kfree idev, the core-2 will do use-after-free for idev.
2. When core-2 do uio_release and put_device, the idev will be double
   freed.

To address this issue, we can get idev atomic & inc idev reference with
minor_lock.

Commit 3823119b9c2b ("drm/crtc: Fix uninit-value bug in

but introduced another.

num_connectors is only initialized if crtc_req->count_connectors > 0,
but it's used regardless. Fix it.

83d36666e5 ida: Fix crash in ida_free when the bitmap is empty
[ Upstream commit af73483f4e8b6f5c68c9aa63257bdd929a9c194a ]

The IDA usually detects double-frees, but that detection failed to
consider the case when there are no nearby IDs allocated and so we have a
NULL bitmap rather than simply having a clear bit.  Add some tests to the
test-suite to be sure we don't inadvertently reintroduce this problem.
Unfortunately they're quite noisy so include a message to disregard
the warnings.

7cd9c291da Input: atkbd - skip ATKBD_CMD_GETID in translated mode
[ Upstream commit 936e4d49ecbc8c404790504386e1422b599dec39 ]

There have been multiple reports of keyboard issues on recent laptop models
which can be worked around by setting i8042.dumbkbd, with the downside
being this breaks the capslock LED.

It seems that these issues are caused by recent laptops getting confused by
ATKBD_CMD_GETID. Rather then adding and endless growing list of quirks for
this, just skip ATKBD_CMD_GETID alltogether on laptops in translated mode.

The main goal of sending ATKBD_CMD_GETID is to skip binding to ps/2
mice/touchpads and those are never used in translated mode.

Examples of laptop models which benefit from skipping ATKBD_CMD_GETID:

* "HP Laptop 15s-fq2xxx", "HP laptop 15s-fq4xxx" and "HP Laptop 15-dy2xxx"
  models the kbd stops working for the first 2 - 5 minutes after boot
  (waiting for EC watchdog reset?)

* On "HP Spectre x360 13-aw2xxx" atkbd fails to probe the keyboard

* At least 9 different Lenovo models have issues with ATKBD_CMD_GETID, see:
  https://github.com/yescallop/atkbd-nogetid

This has been tested on:

1. A MSI B550M PRO-VDH WIFI desktop, where the i8042 controller is not
   in translated mode when no keyboard is plugged in and with a ps/2 kbd
   a "AT Translated Set 2 keyboard" /dev/input/event# node shows up

2. A Lenovo ThinkPad X1 Yoga gen 8 (always has a translated set 2 keyboard)

90a6e1916f tracing: Add size check when printing trace_marker output

If for some reason the trace_marker write does not have a nul byte for the
string, it will overflow the print:

  trace_seq_printf(s, ": %s", field->buf);

The field->buf could be missing the nul byte. To prevent overflow, add the
max size that the buf can be by using the event size and the field
location.

  int max = iter->ent_size - offsetof(struct print_entry, buf);

  trace_seq_printf(s, ": %*.s", max, field->buf);

e50c22336a jbd2: fix soft lockup in journal_finish_inode_data_buffers()
[ Upstream commit 6c02757c936063f0631b4e43fe156f8c8f1f351f ]

There's issue when do io test:

Analyzed informations from vmcore as follows:
(1) There are about 5k+ jbd2_inode in 'commit_transaction->t_inode_list';
(2) Now is processing the 855th jbd2_inode;
(3) JBD2 task has TIF_NEED_RESCHED flag;
(4) There's no pags in address_space around the 855th jbd2_inode;
(5) There are some process is doing drop caches;
(6) Mounted with 'nodioread_nolock' option;
(7) 128 CPUs;

According to informations from vmcore we know 'journal->j_list_lock' spin lock
competition is fierce. So journal_finish_inode_data_buffers() maybe process
slowly. Theoretically, there is scheduling point in the filemap_fdatawait_range_keep_errors().
However, if inode's address_space has no pages which taged with PAGECACHE_TAG_WRITEBACK,
will not call cond_resched(). So may lead to soft lockup.
journal_finish_inode_data_buffers
  filemap_fdatawait_range_keep_errors
    __filemap_fdatawait_range
      while (index <= end)
        nr_pages = pagevec_lookup_range_tag(&pvec, mapping, &index, end, PAGECACHE_TAG_WRITEBACK);
        if (!nr_pages)
           break;    --> If 'nr_pages' is equal zero will break, then will not call cond_resched()
        for (i = 0; i < nr_pages; i++)
          wait_on_page_writeback(page);
        cond_resched();

To solve above issue, add scheduling point in the journal_finish_inode_data_buffers();

97325b35e6 neighbour: Don't let neigh_forced_gc() disable preemption for long
[ Upstream commit e5dc5afff62f3e97e86c3643ec9fcad23de4f2d3 ]

We are seeing cases where neigh_cleanup_and_release() is called by
neigh_forced_gc() many times in a row with preemption turned off.
When running on a low powered CPU at a low CPU frequency, this has
been measured to keep preemption off for ~10 ms. That's not great on a
system with HZ=1000 which expects tasks to be able to schedule in
with ~1ms latency.

65d0e530ad drm/crtc: Fix uninit-value bug in drm_mode_setcrtc
[ Upstream commit 3823119b9c2b5f9e9b760336f75bc989b805cde6 ]

The connector_set contains uninitialized values when allocated with
kmalloc_array. However, in the "out" branch, the logic assumes that any
element in connector_set would be equal to NULL if failed to
initialize, which causes the bug reported by Syzbot. The fix is to use
an extra variable to keep track of how many connectors are initialized
indeed, and use that variable to decrease any refcounts in the "out"
branch.

c73025ddca drm/exynos: fix a wrong error checking
[ Upstream commit 8d1b7809684c688005706125b804e1f9792d2b1b ]

Fix a wrong error checking in exynos_drm_dma.c module.

In the exynos_drm_register_dma function, both arm_iommu_create_mapping()
and iommu_get_domain_for_dev() functions are expected to return NULL as
an error.

However, the error checking is performed using the statement
if(IS_ERR(mapping)), which doesn't provide a suitable error value.
So check if 'mapping' is NULL, and if it is, return -ENODEV.

This issue[1] was reported by Dan.

Changelog v1:
- fix build warning.

1150f299ae debugfs: fix automount d_fsdata usage
[ Upstream commit 0ed04a1847a10297595ac24dc7d46b35fb35f90a ]

debugfs_create_automount() stores a function pointer in d_fsdata,
but since commit 7c8d469877b1 ("debugfs: add support for more
elaborate ->d_fsdata") debugfs_release_dentry() will free it, now
conditionally on DEBUGFS_FSDATA_IS_REAL_FOPS_BIT, but that's not
set for the function pointer in automount. As a result, removing
an automount dentry would attempt to free the function pointer.
Luckily, the only user of this (tracing) never removes it.

Nevertheless, it's safer if we just handle the fsdata in one way,
namely either DEBUGFS_FSDATA_IS_REAL_FOPS_BIT or allocated. Thus,
change the automount to allocate it, and use the real_fops in the
data to indicate whether or not automount is filled, rather than
adding a type tag. At least for now this isn't actually needed,
but the next changes will require it.

Also check in debugfs_file_get() that it gets only called
on regular files, just to make things clearer.

5df0b3c569 f2fs: explicitly null-terminate the xattr list
commit e26b6d39270f5eab0087453d9b544189a38c8564 upstream.

When setting an xattr, explicitly null-terminate the xattr list.  This
eliminates the fragile assumption that the unused xattr space is always
zeroed.

f5419b06be PCI: Disable ATS for specific Intel IPU E2000 devices
commit a18615b1cfc04f00548c60eb9a77e0ce56e848fd upstream.

Due to a hardware issue in A and B steppings of Intel IPU E2000, it expects
wrong endianness in ATS invalidation message body. This problem can lead to
outdated translations being returned as valid and finally cause system
instability.

To prevent such issues, add quirk_intel_e2000_no_ats() to disable ATS for
vulnerable IPU E2000 devices.
