Pull SELinux updates from Paul Moore:
"We've got twenty SELinux patches for the v5.7 merge window, the
highlights are below:
- Deprecate setting /sys/fs/selinux/checkreqprot to 1.
This flag was originally created to deal with legacy userspace and
the READ_IMPLIES_EXEC personality flag. We changed the default from
1 to 0 back in Linux v4.4 and now we are taking the next step of
deprecating it, at some point in the future we will take the final
step of rejecting 1.
- Allow kernfs symlinks to inherit the SELinux label of the parent
directory. In order to preserve backwards compatibility this is
protected by the genfs_seclabel_symlinks SELinux policy capability.
- Optimize how we store filename transitions in the kernel, resulting
in some significant improvements to policy load times.
- Do a better job calculating our internal hash table sizes which
resulted in additional policy load improvements and likely general
SELinux performance improvements as well.
- Remove the unused initial SIDs (labels) and improve how we handle
initial SIDs.
- Enable per-file labeling for the bpf filesystem.
- Ensure that we properly label NFS v4.2 filesystems to avoid a
temporary unlabeled condition.
- Add some missing XFS quota command types to the SELinux quota
access controls.
- Fix a problem where we were not updating the seq_file position
index correctly in selinuxfs.
- We consolidate some duplicated code into helper functions.
- A number of list to array conversions.
- Update Stephen Smalley's email address in MAINTAINERS"

'minItems' and 'maxItems' apply at the same level as 'items' schemas as
the keywords apply to arrays. What's currently defined is a 3
dimensional matrix with the outer size being undefined. To fix this,
minItems/maxItems needs to be moved up a level.
With this fixed, the example fails validation. For matrix types, the dts
syntax must use brackets (<>) matching the schema definition. In this
case, the inner array size is 2 elements, so let's add the correct
bracketing.

There's no point allowing anything else but "psci" for the corresponding

Pull audit updates from Paul Moore:
"We've got two audit patches for the v5.7 merge window with a stellar
14 lines changed between the two patches. The patch descriptions are
far more lengthy than the patches themselves, which is a very good
thing for patches this size IMHO. The patches pass our test suites and
a quick summary is below:
- Stop logging inode information when updating an audit file watch.
Since we are not changing the inode, or the fact that we are
watching the associated file, the inode information is just noise
that we can do without.
- Fix a problem where mandatory audit records were missing their
accompanying audit records (e.g. SYSCALL records were missing).
The missing records often meant that we didn't have the necessary
context to understand what was going on when the event occurred"

kernel test robot reported "WARNING: held lock freed!" triggered by
unittest_gpio_remove(), which should not have been called because
the related gpio overlay was not tracked. Another overlay that
was tracked had previously used the same id as the gpio overlay
but had not been untracked when the overlay was removed. Thus the
clean up function of_unittest_destroy_tracked_overlays() incorrectly
attempted to remove the reused overlay id.
Patch contents:
- Create tracking related helper functions
- Change BUG() to WARN_ON() for overlay id related issues
- Add some additional error checking for valid overlay id values
- Add the missing overlay untrack
- update comment on expectation that overlay ids are assigned in
sequence

Pull gfs2 updates from Bob Peterson:
"We've got a lot of patches (39) for this merge window. Most of these
patches are related to corruption that occurs when journals are
replayed. For example:
1. A node fails while writing to the file system.
2. Other nodes use the metadata that was once used by the failed
node.
3. When the node returns to the cluster, its journal is replayed, but
the older metadata blocks overwrite the changes from step 2.
Summary:
- Fixed the recovery sequence to prevent corruption during journal
replay.
- Many bug fixes found during recovery testing.
- New improved file system withdraw sequence.
- Fixed how resource group buffers are managed.
- Fixed how metadata revokes are tracked and written.
- Improve processing of IO errors hit by daemons like logd and
quotad.
- Improved error checking in metadata writes.
- Fixed how qadata quota data structures are managed"

There's a typo 'nvmem-cells-names' in the schema which means the correct

are wrong too both in that the 2nd entry is not specified correctly and the

"A number of core changes that make things work better in general, code
is simpler and cleaner.
Core changes:
- per-inode file extent tree, for in memory tracking of contiguous
extent ranges to make sure i_size adjustments are accurate
- tree root structures are protected by reference counts, replacing
SRCU that did not cover some cases
- leak detector for tree root structures
- per-transaction pinned extent tracking
- buffer heads are replaced by bios for super block access
- speedup of extent back reference resolution, on an example test
scenario the runtime of send went down from a hour to minutes
- factor out locking scheme used for subvolume writer and NOCOW
exclusion, abstracted as DREW lock, double reader-writer exclusion
(allow either readers or writers)
- cleanup and abstract extent allocation policies, preparation for
zoned device support
- make reflink/clone_range work on inline extents
- add more cancellation point for relocation, improves long response
from 'balance cancel'
- add page migration callback for data pages
- switch to guid for uuids, with additional cleanups of the interface
- make ranged full fsyncs more efficient
- removal of obsolete ioctl flag BTRFS_SUBVOL_CREATE_ASYNC
- remove b-tree readahead from delayed refs paths, avoiding seek and
read unnecessary blocks
Features:
- v2 of ioctl to delete subvolumes, allowing to delete by id and more
future extensions
Fixes:
- fix qgroup rescan worker that could block umount
- fix crash during unmount due to race with delayed inode workers
- fix dellaloc flushing logic that could create unnecessary chunks
under heavy load
- fix missing file extent item for hole after ranged fsync
- several fixes in relocation error handling

Without this commit, a PCIe hotplug port can stop generating interrupts on
hotplug events, so device adds and removals will not be seen:
The pciehp interrupt handler pciehp_isr() reads the Slot Status register
and then writes back to it to clear the bits that caused the interrupt. If
a different interrupt event bit gets set between the read and the write,
pciehp_isr() returns without having cleared all of the interrupt event
bits. If this happens when the MSI isn't masked (which by default it isn't
in handle_edge_irq(), and which it will never be when MSI per-vector
masking is not supported), we won't get any more hotplug interrupts from
that device.
That is expected behavior, according to the PCIe Base Spec r5.0, section
6.7.3.4, "Software Notification of Hot-Plug Events".
Because the Presence Detect Changed and Data Link Layer State Changed event
bits can both get set at nearly the same time when a device is added or
removed, this is more likely to happen than it might seem. The issue was
found (and can be reproduced rather easily) by connecting and disconnecting
an NVMe storage device on at least one system model where the NVMe devices
were being connected to an AMD PCIe port (PCI device 0x1022/0x1483).
Fix the issue by modifying pciehp_isr() to loop back and re-read the Slot
Status register immediately after writing to it, until it sees that all of
the event status bits have been cleared.
[lukas: drop loop count limitation, write "events" instead of "status",
don't loop back in INTx and poll modes, tweak code comment & commit msg]

David Hoyer reports that powering pciehp slots up or down via sysfs may
hang: The call to wait_event() in pciehp_sysfs_enable_slot() and
_disable_slot() does not return because ctrl->ist_running remains true.
This flag, which was introduced by commit 157c1062fcd8 ("PCI: pciehp: Avoid
returning prematurely from sysfs requests"), signifies that the IRQ thread
pciehp_ist() is running. It is set to true at the top of pciehp_ist() and
reset to false at the end. However there are two additional return
statements in pciehp_ist() before which the commit neglected to reset the
flag to false and wake up waiters for the flag.
That omission opens up the following race when powering up the slot:
* pciehp_ist() runs because a PCI_EXP_SLTSTA_PDC event was requested
by pciehp_sysfs_enable_slot()
* pciehp_ist() turns on slot power via the following call stack:
pciehp_handle_presence_or_link_change() -> pciehp_enable_slot() ->
__pciehp_enable_slot() -> board_added() -> pciehp_power_on_slot()
* after slot power is turned on, the link comes up, resulting in a
PCI_EXP_SLTSTA_DLLSC event
* the IRQ handler pciehp_isr() stores the event in ctrl->pending_events
and returns IRQ_WAKE_THREAD
* the IRQ thread is already woken (it's bringing up the slot), but the
genirq code remembers to re-run the IRQ thread after it has finished
(such that it can deal with the new event) by setting IRQTF_RUNTHREAD
via __handle_irq_event_percpu() -> __irq_wake_thread()
* the IRQ thread removes PCI_EXP_SLTSTA_DLLSC from ctrl->pending_events
via board_added() -> pciehp_check_link_status() in order to deal with
presence and link flaps per commit 6c35a1ac3da6 ("PCI: pciehp:
Tolerate initially unstable link")
* after pciehp_ist() has successfully brought up the slot, it resets
ctrl->ist_running to false and wakes up the sysfs requester
* the genirq code re-runs pciehp_ist(), which sets ctrl->ist_running
to true but then returns with IRQ_NONE because ctrl->pending_events
is empty
* pciehp_sysfs_enable_slot() is finally woken but notices that
ctrl->ist_running is true, hence continues waiting
The only way to get the hung task going again is to trigger a hotplug
event which brings down the slot, e.g. by yanking out the card.
The same race exists when powering down the slot because remove_board()
likewise clears link or presence changes in ctrl->pending_events per commit
3943af9d01e9 ("PCI: pciehp: Ignore Link State Changes after powering off a
slot") and thereby may cause a re-run of pciehp_ist() which returns with
IRQ_NONE without resetting ctrl->ist_running to false.
Fix by adding a goto label before the teardown steps at the end of
pciehp_ist() and jumping to that label from the two return statements which
currently neglect to reset the ctrl->ist_running flag.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.
