Pull vfs fix from Christian Brauner:
"Beginning of the merge window we introduced the vfs{g,u}id_t types in c0cec97f720e ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().
When userspace passes -1 for an ownership change the ownership fields
in struct iattr stay uninitialized. Usually this is fine because any
code making use of any fields in struct iattr must check the
->ia_valid field whether the value of interest has been initialized.
That's true for all struct iattr passing code.
However, over the course of the last year with more heavy use of KMSAN
we found quite a few places that got this wrong. A recent one I fixed
was 53505e12955a ("9p: only copy valid iattrs in 9P2000.L setattr
implementation").
But we also have LSM hooks. Actually we have two. The first one is
security_inode_setattr() in notify_change() which does the right thing
and passes the full struct iattr down to LSMs and thus LSMs can check
whether it is initialized.
But then we also have security_path_chown() which passes down a path
argument and the target ownership as the filesystem would see it. For
the latter we now generate the target values based on struct iattr and
pass it down. However, when userspace passes -1 then struct iattr
isn't initialized.
This patch simply initializes ->ia_vfs{g,u}id with INVALID_VFS{G,U}ID
so the hook continue to see invalid ownership when -1 is passed from
userspace. The only LSM that cares about the actual values is Tomoyo.
The vfs codepaths don't look at these fields without ->ia_valid being
set so there's no harm in initializing ->ia_vfs{g,u}id. Arguably this
is also safer since we can't end up copying valid ownership values
when invalid ownership values should be passed.
This only affects mainline. No kernel has been released with this and
thus no backport is needed. The commit is thus marked with a Fixes:
tag but annotated with "# mainline only" (I didn't quite remember what

Beginning of the merge window we introduced the vfs{g,u}id_t types in c0cec97f720e ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().
During that change we forgot to account for the case were the passed
ownership value is -1. In this case the ownership fields in struct iattr
aren't initialized but we rely on them being initialized by the time we
generate the ownership to pass down to the LSMs. All the major LSMs
don't care about the ownership values at all. Only Tomoyo uses them and
so it took a while for syzbot to unearth this issue.
Fix this by initializing the ownership fields and do it within the
retry_deleg block. While notify_change() doesn't alter the ownership
fields currently we shouldn't rely on it.
Since no kernel has been released with these changes this does not
needed to be backported to any stable kernels.
During the code change to add the support for devres-managed card
instance, we put an explicit kfree(card) call at the error path in
snd_card_new(). This is needed for the early error path before the
card is initialized with the device, but is rather superfluous and
causes a double-free at the error path after the card instance is
initialized, as the destructor of the card object already contains a
kfree() call.
This patch fixes the double-free situation by removing the superfluous
kfree(). Meanwhile we need to call kfree() explicitly for the early
error path, so it's added there instead.

ALSA: hda/realtek: Add quirk for ASUS GA503R laptop
The ASUS G15 2022 (GA503R) series laptop has the same node-to-DAC pairs
as early models and the G14, this includes bass speakers which are by
default mapped incorrectly to the 0x06 node.
Just as with the 5570 (and the other Dell laptops), this enables the two
subwoofer speakers on the Dell Precision 5530 together with the main
ones, significantly increasing the audio quality. I've tested this
myself on a 5530 and can confirm it's working as expected.
There's a bug in blkdev_issue_secure_erase. The statement
"unsigned int len = min_t(sector_t, nr_sects, max_sectors);"
sets the variable "len" to the length in sectors, but the statement
"bio->bi_iter.bi_size = len" treats it as if it were in bytes.
The statements "sector += len << SECTOR_SHIFT" and "nr_sects -= len <<
SECTOR_SHIFT" are thinko.
The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.
This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
ARCH=parisc -> build 32-bit kernel
ARCH=parisc64 -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).
The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

When an external device generated a level based interrupt then the
interrupt controller could miss the interrupt. The reason is that the
interrupt controller can detect only link changes.
In the following example, if there is a PHY that generates an interrupt
then the following would happen. The GPIO detected that the interrupt
line changed, and then the 'ocelot_irq_handler' was called. Here it
detects which GPIO line saw the change and for that will call the
following:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask
And this works fine for simple cases, but if the PHY generates many
interrupts, for example when doing PTP timestamping, then the following
could happen. Again the function 'ocelot_irq_handler' will be called
and then from here the following could happen:
1. irq_mask
2. phy interrupt routine
3. irq_eoi
4. irq_unmask
Right before step 3(irq_eoi), the PHY will generate another interrupt.
Now the interrupt controller will acknowledge the change in the
interrupt line. So we miss the interrupt.
A solution will be to use 'handle_level_irq' instead of
'handle_fasteoi_irq', because for this will change routine order of
handling the interrupt.
1. irq_mask
2. irq_ack
3. phy interrupt routine
4. irq_unmask
And now if the PHY will generate a new interrupt before irq_unmask, the
interrupt controller will detect this because it already acknowledge the
change in interrupt line at step 2(irq_ack).
But this is not the full solution because there is another issue. In
case there are 2 PHYs that share the interrupt line. For example phy1
generates an interrupt, then the following can happen:
1.irq_mask
2.irq_ack
3.phy0 interrupt routine
4.phy1 interrupt routine
5.irq_unmask
In case phy0 will generate an interrupt while clearing the interrupt
source in phy1, then the interrupt line will be kept down by phy0. So
the interrupt controller will not see any changes in the interrupt line.
The solution here is to update 'irq_unmask' such that it can detect if
the interrupt line is still active or not. And if it is active then call
again the procedure to clear the interrupts. But we don't want to do it
every time, only if we know that the interrupt controller has not seen
already that the interrupt line has changed.
While at this, add support also for IRQ_TYPE_LEVEL_LOW.
Commit c22af5daa4f6 ("gpio: Don't fiddle with irqchips marked as

Commit a0f7e7f759cf ("drm/amd/display: fix i386 frame size warning")
aimed to address this for i386 but it did not help x86_64.
To reduce the amount of stack space that
dml30_ModeSupportAndSystemConfigurationFull() uses, mark
UseMinimumDCFCLK() as noinline, using the _for_stack variant for
documentation. While this will increase the total amount of stack usage
between the two functions (1632 and 1304 bytes respectively), it will
make sure both stay below the limit of 2048 bytes for these files. The
aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage
so it should not be reverted in favor of this change.
drm/amd/display: Reduce number of arguments of dml31's CalculateFlipSchedule()

First, it doesn't take into account that CLONE_VFORK can be used with

if its parent dies before the child calls exec. It happens because the parent
clears vfork_done.
Eric W. Biederman suggests installing a time namespace as a task gets a new mm.
It includes all new processes cloned without CLONE_VM and all tasks that call
exec(). This is an user API change, but we think there aren't users that depend
on the old behavior.

btrfs: zoned: wait for extent buffer IOs before finishing a zone
Before sending REQ_OP_ZONE_FINISH to a zone, we need to ensure that
ongoing IOs already finished. Or, we will see a "Zone Is Full" error for
the IOs, as the ZONE_FINISH command makes the zone full.
We ensure that with btrfs_wait_block_group_reservations() and
btrfs_wait_ordered_roots() for a data block group. And, for a metadata
block group, the comparison of alloc_offset vs meta_write_pointer mostly
ensures IOs for the allocated region already sent. However, there still
can be a little time frame where the IOs are sent but not yet completed.
Introduce wait_eb_writebacks() to ensure such IOs are completed for a
metadata block group. It walks the buffer_radix to find extent buffers in
the block group and calls wait_on_extent_buffer_writeback() on them.

1) The cleaner kthread tries to start a transaction to delete an unused
block group, but the metadata reservation can not be satisfied right
away, so a reservation ticket is created and it starts the async
metadata reclaim task (fs_info->async_reclaim_work);
2) Writeback for all the filler inodes with an i_size of 2K starts
(generic/562 creates a lot of 2K files with the goal of filling
metadata space). We try to create an inline extent for them, but we
fail when trying to insert the inline extent with -ENOSPC (at
cow_file_range_inline()) - since this is not critical, we fallback
to non-inline mode (back to cow_file_range()), reserve extents, create
extent maps and create the ordered extents;
3) An unmount starts, enters close_ctree();
4) The async reclaim task is flushing stuff, entering the flush states one
by one, until it reaches RUN_DELAYED_IPUTS. There it runs all current
delayed iputs.
After running the delayed iputs and before calling
btrfs_wait_on_delayed_iputs(), one or more ordered extents complete,
and btrfs_add_delayed_iput() is called for each one through
btrfs_finish_ordered_io() -> btrfs_put_ordered_extent(). This results
in bumping fs_info->nr_delayed_iputs from 0 to some positive value.
So the async reclaim task blocks at btrfs_wait_on_delayed_iputs() waiting
for fs_info->nr_delayed_iputs to become 0;
5) The current transaction is committed by the transaction kthread, we then
start unpinning extents and end up calling btrfs_try_granting_tickets()
through unpin_extent_range(), since we released some space.
This results in satisfying the ticket created by the cleaner kthread at
step 1, waking up the cleaner kthread;
6) At close_ctree() we ask the cleaner kthread to park;
7) The cleaner kthread starts the transaction, deletes the unused block
group, and then calls kthread_should_park(), which returns true, so it
parks. And at this point we have the delayed iputs added by the
completion of the ordered extents still pending;
8) Then later at close_ctree(), when we call:
cancel_work_sync(&fs_info->async_reclaim_work);
We hang forever, since the cleaner was parked and no one else can run
delayed iputs after that, while the reclaim task is waiting for the
remaining delayed iputs to be completed.
Fix this by waiting for all ordered extents to complete and running the
delayed iputs before attempting to stop the async reclaim tasks. Note that
we can not wait for ordered extents with btrfs_wait_ordered_roots() (or
other similar functions) because that waits for the BTRFS_ORDERED_COMPLETE
flag to be set on an ordered extent, but the delayed iput is added after
that, when doing the final btrfs_put_ordered_extent(). So instead wait for
the work queues used for executing ordered extent completion to be empty,
which works because we do the final put on an ordered extent at
btrfs_finish_ordered_io() (while we are in the unmount context).

During early unmount, at close_ctree(), we try to stop the block group

flag BTRFS_FS_UNFINISHED_DROPS to be cleared from fs_info->flags. During
unmount we only clear that flag later, after trying to stop the block
group reclaim task.
Fix that by clearing BTRFS_FS_UNFINISHED_DROPS before trying to stop the
block group reclaim task and after setting BTRFS_FS_CLOSING_START, so that
if the reclaim task is waiting on that bit, it will stop immediately after
being woken, because it sees the filesystem is closing (with a call to
btrfs_fs_closing()), and then returns immediately with -EINTR.
