media: pvrusb2: fix memory leak in pvr_probe

The error handling code in pvr2_hdw_create forgets to unregister the
v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create,
it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,
which leads to that pvr2_hdw_destroy directly returns.

Fix this by adding v4l2_device_unregister to decrease the refcount of
usb interface.

Set allow_cache_hints to 1 for the vb2_queue source and destination queues
in the mediatek vcodec V4L2 driver. This allows us to allocate buffers
with the V4L2_MEMORY_FLAG_NON_COHERENT set. On Mediatek SoCs, this enables
caching for this memory, which vastly improves performance when being read

detiling MM21 video frames in userspace software, such as libyuv or

This change should be safe from race conditions since videobuf2 already
invalidates or flushes the appropriate cache lines in its prepare() and

tests files are correctly decoded with both NV12 and NV12_4L4 pixel
formats. These two files have a resolution of 1016x760.

avoid regressions.

2 years agoext4: fix up test_dummy_encryption handling for new mount API
Eric Biggers [Thu, 26 May 2022 04:04:12 +0000 (21:04 -0700)]
ext4: fix up test_dummy_encryption handling for new mount API

Since ext4 was converted to the new mount API, the test_dummy_encryption
mount option isn't being handled entirely correctly, because the needed
fscrypt_set_test_dummy_encryption() helper function combines
parsing/checking/applying into one function.  That doesn't work well
with the new mount API, which split these into separate steps.

This was sort of okay anyway, due to the parsing logic that was copied
from fscrypt_set_test_dummy_encryption() into ext4_parse_param(),
combined with an additional check in ext4_check_test_dummy_encryption().
However, these overlooked the case of changing the value of
test_dummy_encryption on remount, which isn't allowed but ext4 wasn't
detecting until ext4_apply_options() when it's too late to fail.
Another bug is that if test_dummy_encryption was specified multiple
times with an argument, memory was leaked.

Fix this up properly by using the new helper functions that allow
splitting up the parse/check/apply steps for test_dummy_encryption.

x86/tdx: Handle load_unaligned_zeropad() page-cross to a shared page

load_unaligned_zeropad() can lead to unwanted loads across page boundaries.
The unwanted loads are typically harmless. But, they might be made to
totally unrelated or even unmapped memory. load_unaligned_zeropad()
relies on exception fixup (#PF, #GP and now #VE) to recover from these
unwanted loads.

In TDX guests, the second page can be shared page and a VMM may configure
it to trigger #VE.

The kernel assumes that #VE on a shared page is an MMIO access and tries to
decode instruction to handle it. In case of load_unaligned_zeropad() it
may result in confusion as it is not MMIO access.

Fix it by detecting split page MMIO accesses and failing them.
load_unaligned_zeropad() will recover using exception fixups.

The issue was discovered by analysis and reproduced artificially. It was
not triggered during testing.

Merge tag 'printk-for-5.19-rc3' of git://git./linux/kernel/git/printk/linux

Pull printk fixes from Petr Mladek:
 "Make the global console_sem available for CPU that is handling panic()
  or shutdown.

  This is an old problem when an existing console lock owner might block
  console output, but it became more visible with the kthreads"

* tag 'printk-for-5.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux:
  printk: Wait for the global console lock when the system is going down
  printk: Block console kthreads when direct printing will be required
