Victor Nogueira says:
====================
Notify user space if any actions were flushed before error
This patch series fixes the behaviour of actions flush so that the
kernel always notifies user space whenever it deletes actions during a
flush operation, even if it didn't flush all the actions. This series
also introduces tdc tests to verify this new behaviour.

Add tdc test cases to verify new flush behaviour is correct, which do
the following:
- Try to flush only one action which is being referenced by a filter
- Try to flush three actions where the last one (index 3) is being
referenced by a filter

If during an action flush operation one of the actions is still being
referenced, the flush operation is aborted and the kernel returns to
user space with an error. However, if the kernel was able to flush, for
example, 3 actions and failed on the fourth, the kernel will not notify
user space that it deleted 3 actions before failing.
This patch fixes that behaviour by notifying user space of how many
actions were deleted before flush failed and by setting extack with a
message describing what happened.

Limit the max HW sectors to not exceed this limit. We need to hardcode the

On dm-raid table load (using raid_ctr), dm-raid allocates an array
rs->devs[rs->raid_disks] for the raid device members. rs->raid_disks
is defined by the number of raid metadata and image tupples passed
into the target's constructor.
In the case of RAID layout changes being requested, that number can be
different from the current number of members for existing raid sets as
defined in their superblocks. Example RAID layout changes include:
- raid1 legs being added/removed
- raid4/5/6/10 number of stripes changed (stripe reshaping)
- takeover to higher raid level (e.g. raid5 -> raid6)
When accessing array members, rs->raid_disks must be used in control
loops instead of the potentially larger value in rs->md.raid_disks.
Otherwise it will cause memory access beyond the end of the rs->devs
array.
Fix this by changing code that is prone to out-of-bounds access.
Also fix validate_raid_redundancy() to validate all devices that are
added. Also, use braces to help clean up raid_iterate_devices().
The out-of-bounds memory accesses was discovered using KASAN.
This commit was verified to pass all LVM2 RAID tests (with KASAN
enabled).

EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it had been broken for a decade.
Commit 28438794aba4 ("modpost: fix section mismatch check for exported
init/exit sections") fixed it so modpost started to warn it again, then
this showed up:
MODPOST vmlinux.symvers
WARNING: modpost: vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup()
The symbol tick_nohz_full_setup is exported and annotated __init
Fix this by removing the __init annotation of tick_nohz_full_setup or drop the export.
Drop the export because tick_nohz_full_setup() is only called from the
built-in code in kernel/sched/isolation.c.

When br_netfilter module is loaded, skbs may be diverted to the
ipv4/ipv6 hooks, just like as if we were routing.
Unfortunately, bridge filter hooks with priority 0 may be skipped
in this case.
Example:
1. an nftables bridge ruleset is loaded, with a prerouting
hook that has priority 0.
2. interface is added to the bridge.
3. no tcp packet is ever seen by the bridge prerouting hook.
4. flush the ruleset
5. load the bridge ruleset again.
6. tcp packets are processed as expected.
After 1) the only registered hook is the bridge prerouting hook, but its
not called yet because the bridge hasn't been brought up yet.
After 2), hook order is:
0 br_nf_pre_routing // br_netfilter internal hook
0 chain bridge f prerouting // nftables bridge ruleset
The packet is diverted to br_nf_pre_routing.
If call-iptables is off, the nftables bridge ruleset is called as expected.
But if its enabled, br_nf_hook_thresh() will skip it because it assumes
that all 0-priority hooks had been called previously in bridge context.
To avoid this, check for the br_nf_pre_routing hook itself, we need to
resume directly after it, even if this hook has a priority of 0.
Unfortunately, this still results in different packet flow.
With this fix, the eval order after in 3) is:
1. br_nf_pre_routing
2. ip(6)tables (if enabled)
3. nftables bridge
but after 5 its the much saner:
1. nftables bridge
2. br_nf_pre_routing
3. ip(6)tables (if enabled)
Unfortunately I don't see a solution here:
It would be possible to move br_nf_pre_routing to a higher priority
so that it will be called later in the pipeline, but this also impacts
ebtables evaluation order, and would still result in this very ordering
problem for all nftables-bridge hooks with the same priority as the
br_nf_pre_routing one.
Searching back through the git history I don't think this has
ever behaved in any other way, hence, no fixes-tag.

When verdict is NF_STOLEN, the skb might have been freed.
When tracing is enabled, this can result in a use-after-free:
1. access to skb->nf_trace
2. access to skb->mark
3. computation of trace id
4. dump of packet payload
To avoid 1, keep a cached copy of skb->nf_trace in the
trace state struct.
Refresh this copy whenever verdict is != STOLEN.
Avoid 2 by skipping skb->mark access if verdict is STOLEN.
3 is avoided by precomputing the trace id.
Only dump the packet when verdict is not "STOLEN".

This patch fixes a race condition.
nft_rhash_update() might fail for two reasons:
- Element already exists in the hashtable.
- Another packet won race to insert an entry in the hashtable.
In both cases, new() has already bumped the counter via atomic_add_unless(),
therefore, decrement the set element counter.

For imported dma-buf objects we leave the object as cache_coherent = 0
across all platforms, which is reasonable given that have no clue what
the memory underneath is, and its not like the driver can ever manually
clflush the pages anyway (like with i915_gem_clflush_object) for such
objects. However on discrete we choose to treat cache_dirty = true as a
programmer error, leading to a warning. The simplest fix looks to be to
just change the ordering in cpu_write_needs_clflush to prevent ever
setting cache_dirty for dma-buf objects on discrete.

INVALID_VFS{U,G}ID represent ids which have no mapping in the target
mnt_usersns. This can happen for a couple of different reasons -- the
source id might be valid but has no mapping in mnt_userns, or the source
id might have been invalid (either due to a failed mapping or because it
was set to invalid to indicate it is uninitialized).
This means that two arbitrary vfs{u,g}ids which are both invalid could
represent two different underlying ids, or they could represent a failed
mapping and an uninitialized value. In these situation the vfs{u,g}id
equality functions evaluate these ids as equal, and care must be taken
when comparing ids to avoid problems. It would be less error prone to
always evaluate two invalid ids as not equal to each other, and to check
explicitly for vfs{u,g}id validity when that is needed.
Change all vfs{u,g}id equality functions to return false when both ids
are invalid. Functions for checking whether an id is valid exist and are
already being used by code which needs to check this.

Before commit 3d5698793897 ("vhost-vdpa: introduce asid based IOTLB")
we call vhost_vdpa_iotlb_free() during the release to clean all regions
mapped in the iotlb.
That commit removed vhost_vdpa_iotlb_free() and added vhost_vdpa_cleanup()
to do some cleanup, including deleting all mappings, but we forgot to call
it in vhost_vdpa_release().
This causes that if an application does not remove all mappings explicitly
(or it crashes), the mappings remain in the iotlb and subsequent
applications may fail if they map the same addresses.
Calling vhost_vdpa_cleanup() also fixes a memory leak since we are not
freeing `v->vdev.vqs` during the release from the same commit.
Since vhost_vdpa_cleanup() calls vhost_dev_cleanup() we can remove its
call from vhost_vdpa_release().

Virtio devices might lose their state when the VMM is restarted
after a suspend to disk (hibernation) cycle. This means that the
guest page size register must be restored for the virtio_mmio legacy
interface, since otherwise the virtio queues are not functional.
This is particularly problematic for QEMU that currently still defaults
to using the legacy interface for virtio_mmio. Write the guest page
size register again in virtio_mmio_restore() to make legacy virtio_mmio
devices work correctly after hibernation.

Most virtio drivers provide freeze/restore callbacks to finish up
device usage before suspend and to reinitialize the virtio device after
resume. However, these callbacks are currently only called when using
virtio_pci. virtio_mmio does not have any PM ops defined.
This causes problems for example after suspend to disk (hibernation),
since the virtio devices might lose their state after the VMM is
restarted. Calling virtio_device_freeze()/restore() ensures that
the virtio devices are re-initialized correctly.
Fix this by implementing the dev_pm_ops for virtio_mmio,
similar to virtio_pci_common.

We currently depend on probe() calling virtio_device_ready() -
which happens after netdev
registration. Since ndo_open() can be called immediately
after register_netdev, this means there exists a race between
ndo_open() and virtio_device_ready(): the driver may start to use the
device (e.g. TX) before DRIVER_OK which violates the spec.
Fix this by switching to use register_netdevice() and protect the
virtio_device_ready() with rtnl_lock() to make sure ndo_open() can
only be called after virtio_device_ready().

It was caused by the 'l' passed into tipc_bcast_rcv() is NULL. When it
creates a node in tipc_node_check_dest(), after inserting the new node
into hashtable in tipc_node_create(), it creates the bc link. However,
there is a gap between this insert and bc link creation, a bc packet
may come in and get the node from the hashtable then try to dereference
its bc link, which is NULL.
This patch is to fix it by moving the bc link creation before inserting
into the hashtable.
Note that for a preliminary node becoming "real", the bc link creation
should also be called before it's rehashed, as we don't create it for
preliminary nodes.

The end of this function could use some cleanup -- the EAGAIN

This appears to be the result of shortform_to_leaf creating a new leaf
buffer as part of adding an xattr to a file. The new leaf buffer is
held and attached to the xfs_attr_intent structure, but then the
filesystem shuts down. Instead of the usual path (which adds the attr
to the held leaf buffer which releases the hold), we instead cancel the
entire deferred operation.
Unfortunately, xfs_attr_cancel_item doesn't release any attached leaf
buffers, so we leak the locked buffer. The CIL cannot do anything
about that, and hangs. Fix this by teaching it to release leaf buffers,
and make XFS a little more careful about not leaving a dangling
reference.
The prologue of xfs_attri_item_recover is (in this author's opinion) a
little hard to figure out, so I'll clean that up in the next patch.

Now that we introduced new infrastructure to increase the type safety
for filesystems supporting idmapped mounts port the first part of the
vfs over to them.
This ports the attribute changes codepaths to rely on the new better
helpers using a dedicated type.
Before this change we used to take a shortcut and place the actual
values that would be written to inode->i_{g,u}id into struct iattr. This
had the advantage that we moved idmappings mostly out of the picture
early on but it made reasoning about changes more difficult than it
should be.
The filesystem was never explicitly told that it dealt with an idmapped
mount. The transition to the value that needed to be stored in
inode->i_{g,u}id appeared way too early and increased the probability of
bugs in various codepaths.
We know place the same value in struct iattr no matter if this is an
idmapped mount or not. The vfs will only deal with type safe
vfs{g,u}id_t. This makes it massively safer to perform permission checks
as the type will tell us what checks we need to perform and what helpers
we need to use.
Fileystems raising FS_ALLOW_IDMAP can't simply write ia_vfs{g,u}id to
inode->i_{g,u}id since they are different types. Instead they need to
use the dedicated vfs{g,u}id_to_k{g,u}id() helpers that map the
vfs{g,u}id into the filesystem.
The other nice effect is that filesystems like overlayfs don't need to
care about idmappings explicitly anymore and can simply set up struct
iattr accordingly directly.

Port the is_quota_modification() and dqout_transfer() helper to type
safe vfs{g,u}id_t. Since these helpers are only called by a few
filesystems don't introduce a new helper but simply extend the existing
helpers to pass down the mount's idmapping.
Note, that this is a non-functional change, i.e. nothing will have
happened here or at the end of this series to how quota are done! This
a change necessary because we will at the end of this series make
ownership changes easier to reason about by keeping the original value
in struct iattr for both non-idmapped and idmapped mounts.
For now we always pass the initial idmapping which makes the idmapping
functions these helpers call nops.
This is done because we currently always pass the actual value to be
written to i_{g,u}id via struct iattr. While this allowed us to treat
the {g,u}id values in struct iattr as values that can be directly
written to inode->i_{g,u}id it also increases the potential for
confusion for filesystems.
Now that we are have dedicated types to prevent this confusion we will
ultimately only map the value from the idmapped mount into a filesystem
value that can be written to inode->i_{g,u}id when the filesystem
actually updates the inode. So pass down the initial idmapping until we
finished that conversion at which point we pass down the mount's
idmapping.
Since struct iattr uses an anonymous union with overlapping types as
supported by the C standard, filesystems that haven't converted to
ia_vfs{g,u}id won't see any difference and things will continue to work
as before. In other words, no functional changes intended with this
change.

remove code duplication. This converts all filesystems supporting
idmapped mounts to make use of these new helpers.
For now we always pass the initial idmapping which makes the idmapping
functions these helpers call nops.
This is done because we currently always pass the actual value to be
written to i_{g,u}id via struct iattr. While this allowed us to treat
the {g,u}id values in struct iattr as values that can be directly
written to inode->i_{g,u}id it also increases the potential for
confusion for filesystems.
Now that we are have dedicated types to prevent this confusion we will
ultimately only map the value from the idmapped mount into a filesystem
value that can be written to inode->i_{g,u}id when the filesystem
actually updates the inode. So pass down the initial idmapping until we
finished that conversion at which point we pass down the mount's
idmapping.
No functional changes intended.
