We previously would call btrfs_check_leaf() if we had the check
integrity code enabled, which meant that we could only run the extended
leaf checks if we had WRITTEN set on the header flags.
This leaves a gap in our checking, because we could end up with
corruption on disk where WRITTEN isn't set on the leaf, and then the
extended leaf checks don't get run which we rely on to validate all of
the item pointers to make sure we don't access memory outside of the
extent buffer.
However, since 732fab95ab ("btrfs: check-integrity: remove
CONFIG_BTRFS_FS_CHECK_INTEGRITY option") we no longer call
btrfs_check_leaf() from btrfs_mark_buffer_dirty(), which means we only
ever call it on blocks that are being written out, and thus have WRITTEN
set, or that are being read in, which should have WRITTEN set.
Add checks to make sure we have WRITTEN set appropriately, and then make
sure __btrfs_check_leaf() always does the item checking. This will
protect us from file systems that have been corrupted and no longer have
WRITTEN set on some of the blocks.
This was hit on a crafted image tweaking the WRITTEN bit and reported by
KASAN as out-of-bound access in the eb accessors. The example is a dir
item at the end of an eb.

David Hildenbrand says:
===================
This series fixes one issue with uffd + shared zeropages on s390x and
fixes that "ordinary" KVM guests can make use of shared zeropages again.
userfaultfd could currently end up mapping shared zeropages into processes
that forbid shared zeropages. This only apples to s390x, relevant for
handling PV guests and guests that use storage kets correctly. Fix it
by placing a zeroed folio instead of the shared zeropage during
UFFDIO_ZEROPAGE instead.
I stumbled over this issue while looking into a customer scenario that
is using:
(1) Memory ballooning for dynamic resizing. Start a VM with, say, 100 GiB
and inflate the balloon during boot to 60 GiB. The VM has ~40 GiB
available and additional memory can be "fake hotplugged" to the VM
later on demand by deflating the balloon. Actual memory overcommit is
not desired, so physical memory would only be moved between VMs.
(2) Live migration of VMs between sites to evacuate servers in case of
emergency.
Without the shared zeropage, during (2), the VM would suddenly consume
100 GiB on the migration source and destination. On the migration source,
where we don't excpect memory overcommit, we could easilt end up crashing
the VM during migration.
Independent of that, memory handed back to the hypervisor using "free page
reporting" would end up consuming actual memory after the migration on the
destination, not getting freed up until reused+freed again.
While there might be ways to optimize parts of this in QEMU, we really
should just support the shared zeropage again for ordinary VMs.
We only expect legcy guests to make use of storage keys, so let's handle
zeropages again when enabling storage keys or when enabling PV. To not
break userfaultfd like we did in the past, don't zap the shared zeropages,
but instead trigger unsharing faults, just like we do for unsharing
KSM pages in break_ksm().
Unsharing faults will simply replace the shared zeropage by a zeroed
anonymous folio. We can already trigger the same fault path using GUP,
when trying to long-term pin a shared zeropage, but also when unmerging
a KSM-placed zeropages, so this is nothing new.
Patch #1 tested on 86-64 by forcing mm_forbids_zeropage() to be 1, and
running the uffd selftests.
Patch #2 tested on s390x: the live migration scenario now works as
expected, and kvm-unit-tests that trigger usage of skeys work well, whereby
I can see detection and unsharing of shared zeropages.
Further (as broken in v2), I tested that the shared zeropage is no
longer populated after skeys are used -- that mm_forbids_zeropage() works
as expected:
./s390x-run s390x/skey.elf \
-no-shutdown \
-chardev socket,id=monitor,path=/var/tmp/mon,server,nowait \
-mon chardev=monitor,mode=readline
Then, in another shell:
# cat /proc/`pgrep qemu`/smaps_rollup | grep Rss
Rss: 31484 kB
# echo "dump-guest-memory tmp" | sudo nc -U /var/tmp/mon
...
# cat /proc/`pgrep qemu`/smaps_rollup | grep Rss
Rss: 160452 kB
-> Reading guest memory does not populate the shared zeropage
Doing the same with selftest.elf (no skeys)
# cat /proc/`pgrep qemu`/smaps_rollup | grep Rss
Rss: 30900 kB
# echo "dump-guest-memory tmp" | sudo nc -U /var/tmp/mon

amdxcp is a platform driver for creating partition devices. libdrm
library identifies a platform device based on 'OF_FULLNAME' or
'MODALIAS'. If two or more devices have the same platform name, drm
library only picks the first device. Platform driver core uses name of
the device to populate 'MODALIAS'. When 'amdgpu_xcp' is used as the base
name, only first partition device gets identified. Assign unique name so
that drm library identifies partition devices separately.
amdxcp doesn't support probe of partitions, it doesn't bother about

The retry loop for SRIOV reset have refcount and memory leak issue.
Depending on which function call fails it can potentially call
amdgpu_amdkfd_pre/post_reset different number of times and causes
kfd_locked count to be wrong. This will block all future attempts at
opening /dev/kfd. The retry loop also leakes resources by calling
amdgpu_virt_init_data_exchange multiple times without calling the
corresponding fini function.
Align with the bare-metal reset path which doesn't have these issues.
This means taking the amdgpu_amdkfd_pre/post_reset functions out of the
reset loop and calling amdgpu_device_pre_asic_reset each retry which
properly free the resources from previous try by calling
amdgpu_virt_fini_data_exchange.

code since it checks the invariants whenever it gets the pointer to the
lock. This means it checks twice the invariants before and after the
access.
Instead, let's move the checking code within the lock area but after any
modification and remove it from the read paths. This would remove (more
than) half of the maps lock overhead.

[BUG]
After kernel commit 86211eea8a ("btrfs: qgroup: validate
btrfs_qgroup_inherit parameter"), user space tool snapper will fail to
create snapshot using its timeline feature.
[CAUSE]
It turns out that, if using timeline snapper would unconditionally pass
btrfs_qgroup_inherit parameter (assigning the new snapshot to qgroup 1/0)
for snapshot creation.
In that case, since qgroup is disabled there would be no qgroup 1/0, and
btrfs_qgroup_check_inherit() would return -ENOENT and fail the whole
snapshot creation.
[FIX]
Just skip the check if qgroup is not enabled.
This is to keep the older behavior for user space tools, as if the
kernel behavior changed for user space, it is a regression of kernel.
Thankfully snapper is also fixing the behavior by detecting if qgroup is
running in the first place, so the effect should not be that huge.

A user with minimum journal size (1024 blocks these days) complained
about the following error triggered by generic/697 test in
ext4_tmpfile():
run fstests generic/697 at 2024-02-28 05:34:46
JBD2: vfstest wants too many credits credits:260 rsv_credits:0 max:256
EXT4-fs error (device loop0) in __ext4_new_inode:1083: error 28
Indeed the credit estimate in ext4_tmpfile() is huge.
EXT4_MAXQUOTAS_INIT_BLOCKS() is 219, then 10 credits from ext4_tmpfile()
itself and then ext4_xattr_credits_for_new_inode() adds more credits
needed for security attributes and ACLs. Now the
EXT4_MAXQUOTAS_INIT_BLOCKS() is in fact unnecessary because we've
already initialized quotas with dquot_init() shortly before and so
EXT4_MAXQUOTAS_TRANS_BLOCKS() is enough (which boils down to 3 credits).

In the post_reset function, if the fast reset didn't succeed, we
are not clearing the fast_reset flag, which prevents firmware
sections from being reloaded. While at it, use panthor_fw_stop()
instead of manually writing DISABLE to the MCU_CONTROL register.

This is already done by vfs_prepare_mode() when creating the upper object
by vfs_create(), vfs_mkdir() and vfs_mknod().
No regressions have been observed in xfstests run with posix acls turned
off for the upper filesystem.

Combine inode creation with opening a file.
There are six separate objects that are being set up: the backing inode,
dentry and file, and the overlay inode, dentry and file. Cleanup in case
of an error is a bit of a challenge and is difficult to test, so careful
review is needed.
All tmpfile testcases except generic/509 now run/pass, and no regressions
are observed with full xfstests.

If, when waiting for a transmit to finish, the wait is interrupted,
then you might get a "transmit timed out" message, even though the
transmit was interrupted and did not actually time out.
Set transmit_in_progress_aborted to true if the
wait_for_completion_killable() call was interrupted and ensure
that the transmit is properly marked as ABORTED.

Keep track if cec_claim_log_addrs() is running, and return -EBUSY
if it is when calling CEC_ADAP_S_LOG_ADDRS.
This prevents a case where cec_claim_log_addrs() could be called
while it was still in progress.

Pull btrfs fixes from David Sterba:
- set correct ram_bytes when splitting ordered extent. This can be
inconsistent on-disk but harmless as it's not used for calculations
and it's only advisory for compression
- fix lockdep splat when taking cleaner mutex in qgroups disable ioctl
- fix missing mutex unlock on error path when looking up sys chunk for
relocation
* tag 'for-6.9-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:

What needs to be asserted is that the pattern fits in the number
of bits provided by the user in patternbits, otherwise it would
be truncated when replicated according to the mask, which is
likely not the intended use of this function.
The pattern argument is a bitmap so use find_last_bit() instead
of fls(). The bit position starts at index 0 so remove "or equal"
from the comparison. XE_MAX_L3_BANK_MASK_BITS would be the
returned value if the pattern is 0, which can be the case on some
platforms.

v3: Use __fls() for long and handle mask == 0 (Lucas De Marchi)

Use submit_bio_wait() instead of hand-rolling our own synchronous
wait. Also allocate the BIO on the stack since we're not deep in
the call stack at this point.
There's no need to kmap the page, since it isn't allocated from HIGHMEM.
Turn the GFP_NOFS allocation into GFP_KERNEL; if the page allocator
enters reclaim, we cannot be called as the filesystem has not yet been
initialised and so has no pages to reclaim.
