If the device doesn't support arpmb we'll crash due to copying user data in
bsg_transport_sg_io_fn().
In the case where ufs_bsg_exec_advanced_rpmb_req() returns an error, do not
set the job's reply_len.

Commit bb9850704c04 ("scsi: ufs: core: Honor runtime/system PM levels if
set by host controller drivers") introduced the check for setting default
PM levels only if the levels are uninitialized by the host controller
drivers. But it missed the fact that the levels could be initialized to 0
(UFS_PM_LVL_0) on purpose by the controller drivers. Even though none of
the drivers are doing so now, the logic should be fixed irrespectively.
So set the default levels unconditionally before calling ufshcd_hba_init()
API which initializes the controller drivers. It ensures that the
controller drivers could override the default levels if required.

After commit 1bad6c4a57ef ("scsi: zero per-cmd private driver data for each
MQ I/O"), the xen-scsifront/virtio_scsi/snic drivers all removed code that
explicitly zeroed driver-private command data.
In combination with commit 464a00c9e0ad ("scsi: core: Kill DRIVER_SENSE"),
after virtio_scsi performs a capacity expansion, the first request will
return a unit attention to indicate that the capacity has changed. And then
the original command is retried. As driver-private command data was not
cleared, the request would return UA again and eventually time out and fail.

* Fixes for virtual planes, namely to drop extraneous return and fix

It's not possible to call nvme_state_ctrl_state with holding a spin
lock, because nvme_state_ctrl_state calls cancel_delayed_work_sync
when fastfail is enabled.
Instead syncing the ASSOC_FLAG and state transitions using a lock, it's
possible to only rely on the state machine transitions. That means
nvme_fc_ctrl_connectivity_loss should unconditionally call
nvme_reset_ctrl which avoids the read race on the ctrl state variable.
Actually, it's not necessary to test in which state the ctrl is, the
reset work will only scheduled when the state machine is in LIVE state.
In nvme_fc_create_association, the LIVE state can only be entered if it
was previously CONNECTING. If this is not possible then the reset
handler got triggered. Thus just error out here.

Vladimir reports that a race condition to attach a VMID to a stage-2 MMU
sometimes results in a vCPU entering the guest with a VMID of 0:
| CPU1 | CPU2
| |
| | kvm_arch_vcpu_ioctl_run
| | vcpu_load <= load VTTBR_EL2
| | kvm_vmid->id = 0
| |
| kvm_arch_vcpu_ioctl_run |
| vcpu_load <= load VTTBR_EL2 |
| with kvm_vmid->id = 0|
| kvm_arm_vmid_update <= allocates fresh |
| kvm_vmid->id and |
| reload VTTBR_EL2 |
| |
| | kvm_arm_vmid_update <= observes that kvm_vmid->id
| | already allocated,
| | skips reload VTTBR_EL2
Oh yeah, it's as bad as it looks. Remember that VHE loads the stage-2
MMU eagerly but a VMID only gets attached to the MMU later on in the
KVM_RUN loop.
Even in the "best case" where VTTBR_EL2 correctly gets reprogrammed
before entering the EL1&0 regime, there is a period of time where
hardware is configured with VMID 0. That's completely insane. So, rather
than decorating the 'late' binding with another hack, just allocate the
damn thing up front.
Attaching a VMID from vcpu_load() is still rollover safe since
(surprise!) it'll always get called after a vCPU was preempted.
Excuse me while I go find a brown paper bag.

Fuse allows the value of a symlink to change and this property is exploited
by some filesystems (e.g. CVMFS).
It has been observed, that sometimes after changing the symlink contents,
the value is truncated to the old size.
This is caused by fuse_getattr() racing with fuse_reverse_inval_inode().
fuse_reverse_inval_inode() updates the fuse_inode's attr_version, which
results in fuse_change_attributes() exiting before updating the cached
attributes
This is okay, as the cached attributes remain invalid and the next call to
fuse_change_attributes() will likely update the inode with the correct
values.
The reason this causes problems is that cached symlinks will be
returned through page_get_link(), which truncates the symlink to
inode->i_size. This is correct for filesystems that don't mutate
symlinks, but in this case it causes bad behavior.
The solution is to just remove this truncation. This can cause a
regression in a filesystem that relies on supplying a symlink larger than
the file size, but this is unlikely. If that happens we'd need to make
this behavior conditional.

The simple-pm-bus driver only enables runtime PM for some buses
('simple-pm-bus') yet has started calling pm_runtime_force_suspend() and
pm_runtime_force_resume() during system suspend unconditionally.
This currently works, but that is not obvious and depends on
implementation details which may change at some point.
Add dedicated system sleep ops and only call pm_runtime_force_suspend()
and pm_runtime_force_resume() for buses that use runtime PM to avoid any
future surprises.

Fixed a possible UAF problem in driver_override_show() in drivers/cdx/cdx.c
This function driver_override_show() is part of DEVICE_ATTR_RW, which
includes both driver_override_show() and driver_override_store().
These functions can be executed concurrently in sysfs.
The driver_override_store() function uses driver_set_override() to
update the driver_override value, and driver_set_override() internally
locks the device (device_lock(dev)). If driver_override_show() reads
cdx_dev->driver_override without locking, it could potentially access
a freed pointer if driver_override_store() frees the string
concurrently. This could lead to printing a kernel address, which is a
security risk since DEVICE_ATTR can be read by all users.
Additionally, a similar pattern is used in drivers/amba/bus.c, as well
as many other bus drivers, where device_lock() is taken in the show
function, and it has been working without issues.
This potential bug was detected by our experimental static analysis
tool, which analyzes locking APIs and paired functions to identify
data races and atomicity violations.

get_direction() callback as per its API contract. Some drivers have been

gpiochip_add_data() in contexts where it has always silently failed.
Until we audit all drivers, replace the bail-out to a kernel log

====================
net: remove the single page frag cache for good
This is another attempt at reverting commit dbae2b062824 ("net: skb:
introduce and use a single page frag cache"), as it causes regressions
in specific use-cases.
Reverting such commit uncovers an allocation issue for build with
CONFIG_MAX_SKB_FRAGS=45, as reported by Sabrina.
This series handle the latter in patch 1 and brings the revert in patch
2.
Note that there is a little chicken-egg problem, as I included into the
patch 1's changelog the splat that would be visible only applying first
the revert: I think current patch order is better for bisectability,
still the splat is useful for correct attribution.

After the previous commit is finally safe to revert commit dbae2b062824
("net: skb: introduce and use a single page frag cache"): do it here.
The intended goal of such change was to counter a performance regression
introduced by commit 3226b158e67c ("net: avoid 32 x truesize
under-estimation for tiny skbs").
Unfortunately, the blamed commit introduces another regression for the
virtio_net driver. Such a driver calls napi_alloc_skb() with a tiny
size, so that the whole head frag could fit a 512-byte block.
The single page frag cache uses a 1K fragment for such allocation, and
the additional overhead, under small UDP packets flood, makes the page
allocator a bottleneck.
Thanks to commit bf9f1baa279f ("net: add dedicated kmem_cache for
typical/small skb->head"), this revert does not re-introduce the
original regression. Actually, in the relevant test on top of this
revert, I measure a small but noticeable positive delta, just above
noise level.
The revert itself required some additional mangling due to recent updates
in the affected code.
