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.

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.

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.

:
: "This is probably the most interesting bit of the whole NV adventure.
: So far, everything else has been a walk in the park, but this one is
: where the real fun takes place.

: With FEAT_NV2, most of the NV support revolves around tricking a guest
: into accessing memory while it tries to access system registers. The
: hypervisor's job is to handle the context switch of the actual
: registers with the state in memory as needed."

Multi-PTP source support within a network topology has been merged,
but the hardware timestamp source is not yet exposed to users.
Currently, users only see the PTP index, which does not indicate
whether the timestamp comes from a PHY or a MAC.
Add support for reporting the hwtstamp source using a
hwtstamp-source field, alongside hwtstamp-phyindex, to describe
the origin of the hardware timestamp.
Remove HWTSTAMP_SOURCE_UNSPEC enum value as it is not used at all.

When applying a recent commit to the <uapi/linux/perf_event.h>
header I noticed that we have accumulated quite a bit of
historic noise in this header, so do a bit of spring cleaning:
- Define bitfields in a vertically aligned fashion, like
perf_event_mmap_page::capabilities already does. This
makes it easier to see the distribution and sizing of
bits within a word, at a glance. The following is much
more readable:
__u64 cap_bit0 : 1,
cap_bit0_is_deprecated : 1,
cap_user_rdpmc : 1,
cap_user_time : 1,
cap_user_time_zero : 1,
cap_user_time_short : 1,
cap_____res : 58;
Than:
__u64 cap_bit0:1,
cap_bit0_is_deprecated:1,
cap_user_rdpmc:1,
cap_user_time:1,
cap_user_time_zero:1,
cap_user_time_short:1,
cap_____res:58;
So convert all bitfield definitions from the latter style to the
former style.
- Fix typos and grammar
- Fix capitalization
- Remove whitespace noise
- Harmonize the definitions of various generations and groups of
PERF_MEM_ ABI values.
- Vertically align all definitions and assignments to the same
column (48), as the first definition (enum perf_type_id),
throughout the entire header.
- And in general make the code and comments to be more in sync
with each other and to be more readable overall.
No change in functionality.
Copy the changes over to tools/include/uapi/linux/perf_event.h.

Extend the PIDFD_INFO_COREDUMP ioctl() with the new PIDFD_INFO_COREDUMP
mask flag. This adds the @coredump_mask field to struct pidfd_info.
When a task coredumps the kernel will provide the following information
to userspace in @coredump_mask:
* PIDFD_COREDUMPED is raised if the task did actually coredump.
* PIDFD_COREDUMP_SKIP is raised if the task skipped coredumping (e.g.,
undumpable).
* PIDFD_COREDUMP_USER is raised if this is a regular coredump and
doesn't need special care by the coredump server.
* PIDFD_COREDUMP_ROOT is raised if the generated coredump should be
treated as sensitive and the coredump server should restrict to the
generated coredump to sufficiently privileged users.
The kernel guarantees that by the time the connection is made the all
PIDFD_INFO_COREDUMP info is available.

The console dimension and cursor position are available through the
/dev/vcsa interface already. However the /dev/vcsa header format uses
single-byte fields therefore those values are clamped to 255.
As surprizing as this may seem, some people do use 240-column 67-row
screens (a 1920x1080 monitor with 8x16 pixel fonts) which is getting
close to the limit. Monitors with higher resolution are not uncommon
these days (3840x2160 producing a 480x135 character display) and it is
just a matter of time before someone with, say, a braille display using
the Linux VT console and BRLTTY on such a screen reports a bug about
missing and oddly misaligned screen content.
Let's add VT_GETCONSIZECSRPOS for the retrieval of console size and cursor
position without byte-sized limitations. The actual console size limit as
encoded in vt.c is 32767x32767 so using a short here is appropriate. Then
this can be used to get the cursor position when /dev/vcsa reports 255.
The screen dimension may already be obtained using TIOCGWINSZ and adding
the same information to VT_GETCONSIZECSRPOS might be redundant. However
applications that care about cursor position also care about display
size and having 2 separate system calls to obtain them separately is
wasteful. Also, the cursor position can be queried by writing "\e[6n" to
a tty and reading back the result but that may be done only by the actual
application using that tty and not a sideline observer.

This is comprised of 3 aspects:
- Take note of when applications advertise bracketed paste support via
"\e[?2004h" and "\e[?2004l".
- Insert bracketed paste markers ("\e[200~" and "\e[201~") around pasted
content in paste_selection() when bracketed paste is active.
- Add TIOCL_GETBRACKETEDPASTE to return bracketed paste status so user
space daemons implementing cut-and-paste functionality (e.g. gpm,
BRLTTY) may know when to insert bracketed paste markers.

Problem
========
commit 658eb5ab916d ("delayacct: add delay max to record delay peak")
- adding more fields
commit f65c64f311ee ("delayacct: add delay min to record delay peak")
- adding more fields
commit b016d0873777 ("taskstats: modify taskstats version")
- version bump to 15
Since version 15 (TASKSTATS_VERSION=15) the new layout of the structure
adds fields in the middle of the structure, rendering all old software
incompatible with newer kernels and software compiled against the new
kernel headers incompatible with older kernels.
Solution
=========
move delay max and delay min to the end of taskstat, and bump
the version to 16 after the change

Add a toggleable VM capability to reset the VCPU from userspace by
setting MP_STATE_INIT_RECEIVED through IOCTL.
Reset through a mp_state to avoid adding a new IOCTL.
Do not reset on a transition from STOPPED to RUNNABLE, because it's
better to avoid side effects that would complicate userspace adoption.
The MP_STATE_INIT_RECEIVED is not a permanent mp_state -- IOCTL resets
the VCPU while preserving the original mp_state -- because we wouldn't
gain much from having a new state it in the rest of KVM, but it's a very
non-standard use of the IOCTL.

For UBLK_F_AUTO_BUF_REG, buffer is registered to uring_cmd context
automatically with the provided buffer index. User may provide one wrong
buffer index, or the specified buffer is registered by application already.

fallback by completing the uring_cmd and telling ublk server the
register failure via UBLK_AUTO_BUF_REG_FALLBACK, then ublk server still
can register the buffer from userspace.

UBLK_F_AUTO_BUF_REG
Add UBLK_F_AUTO_BUF_REG for supporting to register buffer automatically
to local io_uring context with provided buffer index.
Add UAPI structure `struct ublk_auto_buf_reg` for holding user parameter
to register request buffer automatically, one 'flags' field is defined, and
there is still 32bit available for future extension, such as, adding one
io_ring FD field for registering buffer to external io_uring.
`struct ublk_auto_buf_reg` is populated from ublk uring_cmd's sqe->addr,
and all existing ublk commands are data-less, so it is just fine to reuse
sqe->addr for this purpose.

The TCA_FLOWER_KEY_CFM enum has a UNSPEC and MAX with _OPT
in the name, but the real attributes don't. Add a MAX that
more reasonably matches the attrs.
The PAD in TCA_TAPRIO is the only attr which doesn't have
_ATTR in it, perhaps signifying that it's not a real attr?
If so interesting idea in abstract but it makes codegen painful.

Patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard
regions", v2.
Introduce the PAGE_IS_GUARD flag in the PAGEMAP_SCAN ioctl to expose
information about guard regions. This allows userspace tools, such as
CRIU, to detect and handle guard regions.
Currently, CRIU utilizes PAGEMAP_SCAN as a more efficient alternative to
parsing /proc/pid/pagemap. Without this change, guard regions are
incorrectly reported as swap-anon regions, leading CRIU to attempt dumping
them and subsequently failing.
The series includes updates to the documentation and selftests to reflect
the new functionality.
This patch (of 3):
Introduce the PAGE_IS_GUARD flag in the PAGEMAP_SCAN ioctl to expose
information about guard regions. This allows userspace tools, such as
CRIU, to detect and handle guard regions.

PTRACE_SET_SYSCALL_INFO is a generic ptrace API that complements
PTRACE_GET_SYSCALL_INFO by letting the ptracer modify details of system
calls the tracee is blocked in.
This API allows ptracers to obtain and modify system call details in a
straightforward and architecture-agnostic way, providing a consistent way
of manipulating the system call number and arguments across architectures.
As in case of PTRACE_GET_SYSCALL_INFO, PTRACE_SET_SYSCALL_INFO also does
not aim to address numerous architecture-specific system call ABI
peculiarities, like differences in the number of system call arguments for
such system calls as pread64 and preadv.
The current implementation supports changing only those bits of system
call information that are used by strace system call tampering, namely,
syscall number, syscall arguments, and syscall return value.
Support of changing additional details returned by
PTRACE_GET_SYSCALL_INFO, such as instruction pointer and stack pointer,
could be added later if needed, by using struct ptrace_syscall_info.flags
to specify the additional details that should be set. Currently, "flags"
and "reserved" fields of struct ptrace_syscall_info must be initialized
with zeroes; "arch", "instruction_pointer", and "stack_pointer" fields are
currently ignored.
PTRACE_SET_SYSCALL_INFO currently supports only PTRACE_SYSCALL_INFO_ENTRY,
PTRACE_SYSCALL_INFO_EXIT, and PTRACE_SYSCALL_INFO_SECCOMP operations.
Other operations could be added later if needed.
Ideally, PTRACE_SET_SYSCALL_INFO should have been introduced along with
PTRACE_GET_SYSCALL_INFO, but it didn't happen. The last straw that
convinced me to implement PTRACE_SET_SYSCALL_INFO was apparent failure to
provide an API of changing the first system call argument on riscv
architecture.
ptrace(2) man page:
long ptrace(enum __ptrace_request request, pid_t pid, void *addr, void *data);
...
PTRACE_SET_SYSCALL_INFO
Modify information about the system call that caused the stop.
The "data" argument is a pointer to struct ptrace_syscall_info
that specifies the system call information to be set.
The "addr" argument should be set to sizeof(struct ptrace_syscall_info)).

Symmetric RSS hash requires that:
* No other fields besides IP src/dst and/or L4 src/dst are set
* If src is set, dst must also be set
This restriction was only enforced when RXNFC was configured after
symmetric hash was enabled. In the opposite order of operations (RXNFC
then symmetric enablement) the check was not performed.
Perform the sanity check on set_rxfh as well, by iterating over all flow
types hash fields and making sure they are all symmetric.
Introduce a function that returns whether a flow type is hashable (not
spec only) and needs to be iterated over. To make sure that no one
forgets to update the list of hashable flow types when adding new flow
types, a static assert is added to draw the developer's attention.
The conversion of uapi #defines to enum is not ideal, but as Jakub
mentioned [1], we have precedent for that.

XFS will be able to support large atomic writes (atomic write > 1x block)
in future. This will be achieved by using different operating methods,
depending on the size of the write.
Specifically a new method of operation based in FS atomic extent remapping
will be supported in addition to the current HW offload-based method.
The FS method will generally be appreciably slower performing than the
HW-offload method. However the FS method will be typically able to
contribute to achieving a larger atomic write unit max limit.
XFS will support a hybrid mode, where HW offload method will be used when
possible, i.e. HW offload is used when the length of the write is
supported, and for other times FS-based atomic writes will be used.
As such, there is an atomic write length at which the user may experience
appreciably slower performance.
Advertise this limit in a new statx field, stx_atomic_write_unit_max_opt.
When zero, it means that there is no such performance boundary.
Masks STATX{_ATTR}_WRITE_ATOMIC can be used to get this new field. This is
ok for older kernels which don't support this new field, as they would
report 0 in this field (from zeroing in cp_statx()) already. Furthermore
those older kernels don't support large atomic writes - apart from block
fops, but there would be consistent performance there for atomic writes
in range [unit min, unit max].

Devlink param and health reporter fmsg use attributes with dynamic type
which is determined according to a different type. Currently used values
are NLA_*. The problem is, they are not part of UAPI. They may change
which would cause a break.
To make this future safe, introduce a enum that shadows NLA_* values in
it and is part of UAPI.
Also, this allows to possibly carry types that are unrelated to NLA_*
values.

Multipath cannot directly provide failover for ioctls in the kernel
because it doesn't know what each ioctl means and which result could
indicate a path error. Userspace generally knows what the ioctl it
issued means and if it might be a path error, but neither does it know
which path the ioctl took nor does it necessarily have the privileges to
fail a path using the control device.
In order to allow userspace to address this situation, implement a
DM_MPATH_PROBE_PATHS ioctl that prompts the dm-mpath driver to probe all
active paths in the current path group to see whether they still work,
and fail them if not. If this returns success, userspace can retry the
ioctl and expect that the previously hit bad path is now failed (or
working again).
The immediate motivation for this is the use of SG_IO in QEMU for SCSI
passthrough. Following a failed SG_IO ioctl, QEMU will trigger probing
to ensure that all active paths are actually alive, so that retrying
SG_IO at least has a lower chance of failing due to a path error.
However, the problem is broader than just SG_IO (it affects any ioctl),
and if applications need failover support for other ioctls, the same
probing can be used.
This is not implemented on the DM control device, but on the DM mpath
block devices, to allow all users who have access to such a block device
to make use of this interface, specifically to implement failover for
ioctls. For the same reason, it is also unprivileged. Its implementation
is effectively just a bunch of reads, which could already be issued by
userspace, just without any guarantee that all the rights paths are
selected.
The probing implemented here is done fully synchronously path by path;
probing all paths concurrently is left as an improvement for the future.

Extend the futex2 interface to be aware of mempolicy.
When FUTEX2_MPOL is specified and there is a MPOL_PREFERRED or
home_node specified covering the futex address, use that hash-map.
Notably, in this case the futex will go to the global node hashtable,
even if it is a PRIVATE futex.
When FUTEX2_NUMA|FUTEX2_MPOL is specified and the user specified node
value is FUTEX_NO_NODE, the MPOL lookup (as described above) will be
tried first before reverting to setting node to the local node.

Extend the futex2 interface to be numa aware.
When FUTEX2_NUMA is specified for a futex, the user value is extended
to two words (of the same size). The first is the user value we all
know, the second one will be the node to place this futex on.
struct futex_numa_32 {
u32 val;
u32 node;
};
When node is set to ~0, WAIT will set it to the current node_id such
that WAKE knows where to find it. If userspace corrupts the node value
between WAIT and WAKE, the futex will not be found and no wakeup will
happen.
When FUTEX2_NUMA is not set, the node is simply an extension of the
hash, such that traditional futexes are still interleaved over the
nodes.
This is done to avoid having to have a separate !numa hash-table.

My initial testing showed that:
perf bench futex hash
reported less operations/sec with private hash. After using the same
amount of buckets in the private hash as used by the global hash then
the operations/sec were about the same.
This changed once the private hash became resizable. This feature added
an RCU section and reference counting via atomic inc+dec operation into
the hot path.
The reference counting can be avoided if the private hash is made
immutable.
Extend PR_FUTEX_HASH_SET_SLOTS by a fourth argument which denotes if the
private should be made immutable. Once set (to true) the a further
resize is not allowed (same if set to global hash).
Add PR_FUTEX_HASH_GET_IMMUTABLE which returns true if the hash can not
be changed.
Update "perf bench" suite.

The futex hash is system wide and shared by all tasks. Each slot
is hashed based on futex address and the VMA of the thread. Due to
randomized VMAs (and memory allocations) the same logical lock (pointer)
can end up in a different hash bucket on each invocation of the
application. This in turn means that different applications may share a
hash bucket on the first invocation but not on the second and it is not
always clear which applications will be involved. This can result in
high latency's to acquire the futex_hash_bucket::lock especially if the
lock owner is limited to a CPU and can not be effectively PI boosted.
Introduce basic infrastructure for process local hash which is shared by
all threads of process. This hash will only be used for a
PROCESS_PRIVATE FUTEX operation.
The hashmap can be allocated via:
prctl(PR_FUTEX_HASH, PR_FUTEX_HASH_SET_SLOTS, num);
A `num' of 0 means that the global hash is used instead of a private
hash.
Other values for `num' specify the number of slots for the hash and the
number must be power of two, starting with two.
The prctl() returns zero on success. This function can only be used
before a thread is created.
The current status for the private hash can be queried via:
num = prctl(PR_FUTEX_HASH, PR_FUTEX_HASH_GET_SLOTS);
which return the current number of slots. The value 0 means that the
global hash is used. Values greater than 0 indicate the number of slots
that are used. A negative number indicates an error.
For optimisation, for the private hash jhash2() uses only two arguments
the address and the offset. This omits the VMA which is always the same.

Figuring out the chosen backend requires information about the set flags
