This patch introduces the options restart_on_error and panic_on_error on
dm-verity.
Previously, restarting on error was handled by the patch
e6a3531dd5, but Google engineers wanted to
have a special option for it.

This reverts commit e6a3531dd5.
The problem that the commit e6a3531dd5
fixes was reported as a security bug, but Google engineers working on
Android and ChromeOS didn't want to change the default behavior, they
want to get -EIO rather than restarting the system, so I am reverting
that commit.
Note also that calling machine_restart from the I/O handling code is
potentially unsafe (the reboot notifiers may wait for the bio that
triggered the restart), but Android uses the reboot notifiers to store
the reboot reason into the PMU microcontroller, so machine_restart must
be used.

- When sched_ext is in bypass mode (e.g. while disabling the BPF scheduler),
it was using one DSQ to implement global FIFO scheduling as all it has to
do is guaranteeing reasonable forward progress. On multi-socket machines,
this can lead to live-lock conditions under certain workloads. Fixed by
splitting the queue used for FIFO scheduling per NUMA node. This required
several preparation patches.
- Hotplug tests on powerpc could reliably trigger deadlock while enabling a
BPF scheduler. This was caused by cpu_hotplug_lock nesting inside
scx_fork_rwsem and then CPU hotplug path trying to fork a new thread while
holding cpu_hotplug_lock. Fixed by restructuring locking in enable and
disable paths so that the two locks are not coupled. This required several
preparation patches which also fixed a couple other issues in the enable
path.
- A build fix for !CONFIG_SMP.
- Userspace tooling sync and updates.

The cpu_emergency_register_virt_callback() function is used
unconditionally by the x86 kvm code, but it is declared (and defined)
conditionally:
#if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);
...
leading to a build error when neither KVM_INTEL nor KVM_AMD support is
enabled:

arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration]

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

Assorted minor syzbot fixes, and for bigger stuff:
- Fix two disk accounting rewrite bugs
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree. This is
set in the transaction commit path, after we've gotten our journal
reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses
was incorrectly skipping this for new updates generated prior to
journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple fixes for disk accounting + device removal. Checking if
acocunting replicas entries were marked in the superblock was being
done at the wrong point, when deltas in the journal could still zero
them out, and then additionally we'd try to add a missing replicas
entry to the superblock without checking if it referred to an invalid
(removed) device.
- A whole slew of repair fixes
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings"
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was
clean
- there shouldn't be pending logged ops if the fs was clean, we now
check for this
- remove_backpointer() doesn't remove a dirent that doesn't actually
point to the inode
- many more fsck errors are AUTOFIX

Pull more bcachefs updates from Kent Overstreet:
"Assorted minor syzbot fixes, and for bigger stuff:
Fix two disk accounting rewrite bugs:
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree.
This is set in the transaction commit path, after we've gotten our
journal reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay
uses was incorrectly skipping this for new updates generated prior
to journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple of fixes for disk accounting + device removal.
Checking if acocunting replicas entries were marked in the
superblock was being done at the wrong point, when deltas in the
journal could still zero them out, and then additionally we'd try
to add a missing replicas entry to the superblock without checking
if it referred to an invalid (removed) device.
A whole slew of repair fixes:
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was
clean
- there shouldn't be pending logged ops if the fs was clean, we now
check for this
- remove_backpointer() doesn't remove a dirent that doesn't actually
point to the inode
- many more fsck errors are AUTOFIX"

selftests: vDSO: align stack for O2-optimized memcpy
The isomorphism neg_if_exp negates the test of a ?: conditional,
making it unnecessary to have an explicit case for a negated test
with the branches inverted.
At the same time, we can disable neg_if_exp in cases where a
different API function may be more suitable for a negated test.
Finally, in the non-patch cases, E matches an expression with
parentheses around it, so there is no need to mention ()
explicitly in the pattern. The () are still needed in the patch
cases, because we want to drop them, if they are present.

* KVM currently invalidates the entirety of the page tables, not just
those for the memslot being touched, when a memslot is moved or deleted.
The former does not have particularly noticeable overhead, but Intel's
TDX will require the guest to re-accept private pages if they are
dropped from the secure EPT, which is a non starter. Actually,
the only reason why this is not already being done is a bug which
was never fully investigated and caused VM instability with assigned
GeForce GPUs, so allow userspace to opt into the new behavior.
* Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
functionality that is on the horizon).
* Rework common MSR handling code to suppress errors on userspace accesses to
unsupported-but-advertised MSRs. This will allow removing (almost?) all of
KVM's exemptions for userspace access to MSRs that shouldn't exist based on
the vCPU model (the actual cleanup is non-trivial future work).
* Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
stores the entire 64-bit value at the ICR offset.
* Fix a bug where KVM would fail to exit to userspace if one was triggered by
a fastpath exit handler.
* Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
there's already a pending wake event at the time of the exit.
* Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
(the SHUTDOWN hits the VM altogether, not the nested guest)
* Overhaul the "unprotect and retry" logic to more precisely identify cases
where retrying is actually helpful, and to harden all retry paths against
putting the guest into an infinite retry loop.
* Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
the shadow MMU.
* Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for

There are a few fixes / cleanups from Vincent, Chunhui, and Petr, but the
most important part of this pull request is the Rust community stepping
up to help maintain both C / Rust code for future Rust module support. We
grow the set of modules maintainers by 3 now, and with this hope to scale to
help address what's needed to properly support future Rust module support.
A lot of exciting stuff coming in future kernel releases.
This has been on linux-next for ~ 3 weeks now with no issues.

If the reader acquires the read lock and then the writer enters the slow
path, while the reader proceeds to the unlock path, the following scenario
can occur without the change:
writer: pcpu_read_count(lock) return 1 (so __do_six_trylock will return 0)
reader: this_cpu_dec(*lock->readers)
reader: smp_mb()
reader: state = atomic_read(&lock->state) (there is no waiting flag set)
writer: six_set_bitmask()
then the writer will sleep forever.

Add a filesystem flag to indicate whether we did a clean recovery -
using c->sb.clean after we've got rw is incorrect, since c->sb is
updated whenever we write the superblock.

We had a bug where disk accounting keys didn't always have their version
field set in journal replay; change the BUG_ON() to a WARN(), and
exclude this case since it's now checked for elsewhere (in the bkey
validate function).
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
This was added to avoid double-counting accounting keys in journal
replay. But applied incorrectly (easily done since it applies to the
transaction commit, not a particular update), it leads to skipping
in-mem accounting for real accounting updates, and failure to give them
a version number - which leads to journal replay becoming very confused
the next time around.
