Add feature UBLK_F_QUIESCE, which adds control command `UBLK_U_CMD_QUIESCE_DEV`
for quiescing device, then device state can become `UBLK_S_DEV_QUIESCED`
or `UBLK_S_DEV_FAIL_IO` finally from ublk_ch_release() with ublk server
cooperation.
This feature can help to support to upgrade ublk server application by
shutting down ublk server gracefully, meantime keep ublk block device
persistent during the upgrading period.
The feature is only available for UBLK_F_USER_RECOVERY.

Filesystems like XFS can implement atomic write I/O using either
REQ_ATOMIC flag set in the bio or via CoW operation. It will be useful
if we have a flag in trace events to distinguish between the two. This
patch adds char 'U' (Untorn writes) to rwbs field of the trace events
if REQ_ATOMIC flag is set in the bio.

In prior kernel versions (5.8-6.8), commit 9f6c61f96f2d9 ("proc/mounts:
add cursor") introduced MNT_CURSOR, a flag used by readers from
/proc/mounts to keep their place while reading the file. Later, commit
2eea9ce4310d8 ("mounts: keep list of mounts in an rbtree") removed this
flag and its value has since been repurposed.
For debuggers iterating over the list of mounts, cursors should be
skipped as they are irrelevant. Detecting whether an element is a cursor
can be difficult. Since the MNT_CURSOR flag is a preprocessor constant,
it's not present in debuginfo, and since its value is repurposed, we
cannot hard-code it. For this specific issue, cursors are possible to
detect in other ways, but ideally, we would be able to read the mount
flag definitions out of the debuginfo. For that reason, convert the
mount flags to an enum.

Notify user space if netdev hooks are updated due to netdev add/remove
events. Send minimal notification messages by introducing
NFT_MSG_NEWDEV/DELDEV message types describing a single device only.
Upon NETDEV_CHANGENAME, the callback has no information about the
interface's old name. To provide a clear message to user space, include
the hook's stored interface name in the notification.

Supporting a 1:n relationship between nft_hook and nf_hook_ops is
convenient since a chain's or flowtable's nft_hooks may remain in place
despite matching interfaces disappearing. This stabilizes ruleset dumps
in that regard and opens the possibility to claim newly added interfaces
which match the spec. Also it prepares for wildcard interface specs
since these will potentially match multiple interfaces.
All spots dealing with hook registration are updated to handle a list of
multiple nf_hook_ops, but nft_netdev_hook_alloc() only adds a single
item for now to retain the old behaviour. The only expected functional
change here is how vanishing interfaces are handled: Instead of dropping
the respective nft_hook, only the matching nf_hook_ops are dropped.
To safely remove individual ops from the list in netdev handlers, an
rcu_head is added to struct nf_hook_ops so kfree_rcu() may be used.
There is at least nft_flowtable_find_dev() which may be iterating
through the list at the same time.

Also a pretty dull wrapper around the hook->ops.dev comparison for now.
Will search the embedded nf_hook_ops list in future. The ugly cast to
eliminate the const qualifier will vanish then, too.
Since this future list will be RCU-protected, also introduce an _rcu()
variant here.

Add the minimal relevant info needed for userspace ("nftables monitor
trace") to provide the conntrack view of the packet:
- state (new, related, established)
- direction (original, reply)
- status (e.g., if connection is subject to dnat)
- id (allows to query ctnetlink for remaining conntrack state info)
Example:
trace id a62 inet filter PRE_RAW packet: iif "enp0s3" ether [..]
[..]
trace id a62 inet filter PRE_MANGLE conntrack: ct direction original ct state new ct id 32
trace id a62 inet filter PRE_MANGLE packet: [..]
[..]
trace id a62 inet filter IN conntrack: ct direction original ct state new ct status dnat-done ct id 32
[..]
In this case one can see that while NAT is active, the new connection
isn't subject to a translation.

While nf_conntrack_id() doesn't need any functionaliy from conntrack, it
does reside in nf_conntrack_core.c -- callers add a module
dependency on conntrack.
Followup patch will need to compute the conntrack id from nf_tables_trace.c
to include it in nf_trace messages emitted to userspace via netlink.
I don't want to introduce a module dependency between nf_tables and
conntrack for this.
Since trace is slowpath, the added indirection is ok.
One alternative is to move nf_conntrack_id to the netfilter/core.c,
but I don't see a compelling reason so far.

Due to the recursion involved, the simplest change is to make it a

fib has two modes:
1. Obtain output device according to source or destination address
2. Obtain the type of the address, e.g. local, unicast, multicast.
'fib daddr type' should return 'local' if the address is configured
in this netns or unicast otherwise.
'fib daddr . iif type' should return 'local' if the address is configured
on the input interface or unicast otherwise, i.e. more restrictive.
However, if the interface is part of a VRF, then 'fib daddr type'
returns unicast even if the address is configured on the incoming
interface.
This is broken for both ipv4 and ipv6.
In the ipv4 case, inet_dev_addr_type must only be used if the
'iif' or 'oif' (strict mode) was requested.
Else inet_addr_type_dev_table() needs to be used and the correct
dev argument must be passed as well so the correct fib (vrf) table
is used.
In the ipv6 case, the bug is similar, without strict mode, dev is NULL
so .flowi6_l3mdev will be set to 0.
Add a new 'nft_fib_l3mdev_master_ifindex_rcu()' helper and use that
to init the .l3mdev structure member.
For ipv6, use it from nft_fib6_flowi_init() which gets called from
both the 'type' and the 'route' mode eval functions.
This provides consistent behaviour for all modes for both ipv4 and ipv6:
If strict matching is requested, the input respectively output device
of the netfilter hooks is used.
Otherwise, use skb->dev to obtain the l3mdev ifindex.
Without this, most type checks in updated nft_fib.sh selftest fail:
FAIL: did not find veth0 . 10.9.9.1 . local in fibtype4
FAIL: did not find veth0 . dead:1::1 . local in fibtype6
FAIL: did not find veth0 . dead:9::1 . local in fibtype6

FAIL: did not find tvrf . dead:1::1 . local in fibtype6
FAIL: did not find tvrf . dead:9::1 . local in fibtype6
FAIL: fib expression address types match (iif in vrf)
(fib errounously returns 'unicast' for all of them, even
though all of these addresses are local to the vrf).

As long as recvmsg() or recvmmsg() is used with cmsg, it is not
possible to avoid receiving file descriptors via SCM_RIGHTS.
This behaviour has occasionally been flagged as problematic, as
it can be (ab)used to trigger DoS during close(), for example, by
passing a FUSE-controlled fd or a hung NFS fd.
For instance, as noted on the uAPI Group page [0], an untrusted peer
could send a file descriptor pointing to a hung NFS mount and then
close it. Once the receiver calls recvmsg() with msg_control, the
descriptor is automatically installed, and then the responsibility
for the final close() now falls on the receiver, which may result
in blocking the process for a long time.
Regarding this, systemd calls cmsg_close_all() [1] after each
recvmsg() to close() unwanted file descriptors sent via SCM_RIGHTS.
However, this cannot work around the issue at all, because the final
fput() may still occur on the receiver's side once sendmsg() with
SCM_RIGHTS succeeds. Also, even filtering by LSM at recvmsg() does
not work for the same reason.
Thus, we need a better way to refuse SCM_RIGHTS at sendmsg().
Let's introduce SO_PASSRIGHTS to disable SCM_RIGHTS.
Note that this option is enabled by default for backward
compatibility.

As explained in the next patch, SO_PASSRIGHTS would have a problem
if we assigned a corresponding bit to socket->flags, so it must be
managed in struct sock.
Mixing socket->flags and sk->sk_flags for similar options will look
confusing, and sk->sk_flags does not have enough space on 32bit system.
Also, as mentioned in commit 16e572626961 ("af_unix: dont send
SCM_CREDENTIALS by default"), SOCK_PASSCRED and SOCK_PASSPID handling
is known to be slow, and managing the flags in struct socket cannot
avoid that for embryo sockets.
Let's move SOCK_PASS{CRED,PIDFD,SEC} to struct sock.
While at it, other SOCK_XXX flags in net.h are grouped as enum.
Note that assign_bit() was atomic, so the writer side is moved down
after lock_sock() in setsockopt(), but the bit is only read once
in sendmsg() and recvmsg(), so lock_sock() is not needed there.

SCM_CREDENTIALS and SCM_SECURITY can be recv()ed by calling
scm_recv() or scm_recv_unix(), and SCM_PIDFD is only used by
scm_recv_unix().
scm_recv() is called from AF_NETLINK and AF_BLUETOOTH.
scm_recv_unix() is literally called from AF_UNIX.
Let's restrict SO_PASSCRED and SO_PASSSEC to such sockets and
SO_PASSPIDFD to AF_UNIX only.
Later, SOCK_PASS{CRED,PIDFD,SEC} will be moved to struct sock

scm_recv() has been placed in scm.h since the pre-git era for no
particular reason (I think), which makes the file really fragile.
For example, when you move SOCK_PASSCRED from include/linux/net.h to
enum sock_flags in include/net/sock.h, you will see weird build failure
due to terrible dependency.
To avoid the build failure in the future, let's move scm_recv(_unix())?
and its callees to scm.c.
Note that only scm_recv() needs to be exported for Bluetooth.
scm_send() should be moved to scm.c too, but I'll revisit later.

On cifs, "DIO reads" (specified by O_DIRECT) need to be differentiated from
"unbuffered reads" (specified by cache=none in the mount parameters). The
difference is flagged in the protocol and the server may behave
differently: Windows Server will, for example, mandate that DIO reads are
block aligned.
Fix this by adding a NETFS_UNBUFFERED_READ to differentiate this from
NETFS_DIO_READ, parallelling the write differentiation that already exists.
cifs will then do the right thing.

Let's make count_memcg_events re-entrant safe against irqs. The only
thing needed is to convert the usage of __this_cpu_add() to
this_cpu_add(). In addition, with re-entrant safety, there is no need to
disable irqs. Also add warnings for in_nmi() as it is not safe against
nmi context.

Originally, the file pages collapse was intended for tmpfs/shmem to merge
into THP in the background. However, now not only tmpfs/shmem can support
large folios, but some other file systems (such as XFS, erofs ...) also
support large folios. Therefore, it is time to decouple the support of
file folios collapse from SHMEM.

The "try_" prefix is confusing, since it made people believe that
try_alloc_pages() is analogous to spin_trylock() and NULL return means
EAGAIN. This is not the case. If it returns NULL there is no reason to
call it again. It will most likely return NULL again. Hence rename it to
alloc_pages_nolock() to make it symmetrical to free_pages_nolock() and
document that NULL means ENOMEM.

Having encountered a trinity report in linux-next (Linked in the 'Closes'
tag) it appears that there are legitimate situations where a file-backed
mapping can be acquired but no file->f_op->mmap or
file->f_op->mmap_prepare is set, at which point do_mmap() should simply
error out with -ENODEV.
Since previously we did not warn in this scenario and it appears we rely
upon this, restore this situation, while retaining a WARN_ON_ONCE() for
the case where both are set, which is absolutely incorrect and must be
addressed and thus always requires a warning.
If further work is required to chase down precisely what is causing this,
then we can later restore this, but it makes no sense to hold up this
series to do so, as this is existing and apparently expected behaviour.

In do_set_pmd(), we always use the folio->page to build PMD mappings for
the entire folio. Since all callers of do_set_pmd() already hold a stable
folio, converting do_set_pmd() to take a folio is safe and more
straightforward.
In addition, to ensure the extensibility of do_set_pmd() for supporting
larger folios beyond PMD size, we keep the 'page' parameter to specify
which page within the folio should be mapped.
No functional changes expected.

We've already gotten the stable locked folio in collapse_pte_mapped_thp(),
so just use folio for set_huge_pmd() to set the PMD entry, which is more
straightforward.
Moreover, we will check the folio size in do_set_pmd(), so we can remove
the unnecessary VM_BUG_ON() in set_huge_pmd(). While we are at it, we can
also remove the PageTransHuge(), as it currently has no callers.

Let's use our new interface. In remap_pfn_range(), we'll now decide
whether we have to track (full VMA covered) or only lookup the cachemode
(partial VMA covered).
Remember what we have to untrack by linking it from the VMA. When
duplicating VMAs (e.g., splitting, mremap, fork), we'll handle it similar
to anon VMA names, and use a kref to share the tracking.
Once the last VMA un-refs our tracking data, we'll do the untracking,
which simplifies things a lot and should sort our various issues we saw
recently, for example, when partially unmapping/zapping a tracked VMA.
This change implies that we'll keep tracking the original PFN range even
after splitting + partially unmapping it: not too bad, because it was not
working reliably before. The only thing that kind-of worked before was
shrinking such a mapping using mremap(): we managed to adjust the
reservation in a hacky way, now we won't adjust the reservation but leave
it around until all involved VMAs are gone.
If that ever turns out to be an issue, we could hook into VM splitting
code and split the tracking; however, that adds complexity that might not
be required, so we'll keep it simple for now.

acpi_parse_cfmws() currently adds empty CFMWS ranges to numa_meminfo with
the expectation that numa_cleanup_meminfo moves them to
numa_reserved_meminfo. There is no need for that indirection when it is
known in advance that these unpopulated ranges are meant for
numa_reserved_meminfo in support of future hotplug / CXL provisioning.
Introduce and use numa_add_reserved_memblk() to add the empty CFMWS ranges
directly.

Other subsystems may make use of the cgroup hierarchy with the cgroup_bpf
support being one such example. For such a feature, it's useful to be able
to hook into cgroup creation and destruction paths to perform
feature-specific initializations and cleanups.
Add cgroup_lifetime_notifier which generates CGROUP_LIFETIME_ONLINE and
CGROUP_LIFETIME_OFFLINE events whenever cgroups are created and destroyed,
respectively.
The next patch will convert cgroup_bpf to use the new notifier and other
uses are planned.

ASoC: Updates for v6.16
The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.
- Conversion of quite a few drivers to newer GPIO APIs.
- More helpers and cleanups from Mormimoto-san.
- Support for a wider range of AVS platforms.
