Describe SECCOMP_FILTER_FLAG_RESTART_BEFORE_RECV in the UAPI header, as
SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV is described above it, and say in
the documentation that supervisors must tolerate ENOENT from
SECCOMP_IOCTL_NOTIF_RECV, which the flag makes routine. Note at the
fget_raw() call that O_PATH files are allowed on purpose.
Build tested ARCH=x86_64 defconfig (kernel/seccomp.o and headers) with
GCC 16.2.0, and SPHINXDIRS=userspace-api htmldocs.

An interrupted user notification wait returns ERESTARTSYS before the
syscall body has run. If the notifying task's handler for the delivered
signal was installed without SA_RESTART, that task sees EINTR even for
calls whose callers do not expect it. This can make fork fail
unexpectedly or make close report EINTR while leaving the descriptor
open. A leaked pipe write end can prevent readers from seeing EOF.
The supervisor cannot repair this result once the interrupted task
removes the notification. If removal happens before receipt, the
supervisor never receives that request; a reply using its ID would fail
with ENOENT. Receiving notifications eagerly only narrows the scheduling
window. WAIT_KILLABLE_RECV protects supervisor processing after receipt,
but deliberately leaves the pre-receive wait interruptible.
A sandbox also cannot transparently fix this in the target. It cannot
require arbitrary workloads to retry calls such as fork and close.
Retrying close on EINTR is unsafe when the native syscall has already
released the descriptor. Forcing SA_RESTART on application handlers
would change cancellation behavior for other blocking calls.
Sandlock encounters this while mediating process creation to enforce
process limits. For example, dash installs its SIGCHLD handler without
SA_RESTART. While dash is creating a pipeline, an earlier child can exit
and generate SIGCHLD while dash waits for a fork notification to be
received. The interrupted wait then makes fork return EINTR, causing
dash to report "Cannot fork". Removing fork from notification mediation
would bypass the process-limit enforcement that sandlock needs.
Add SECCOMP_FILTER_FLAG_RESTART_BEFORE_RECV, requiring NEW_LISTENER.
Under notify_lock, convert an interrupted wait's ERESTARTSYS to
ERESTARTNOINTR only while the notification remains INIT. The notifying
task's signal handler still runs; if it returns normally, syscall entry
and the filter are evaluated again.
Keep this opt-in because commit c2aa2dfef243 ("seccomp: Add
wait_killable semantic to seccomp user notifier") deliberately preserved
pre-receipt interruption so workloads could abandon requests before the
supervisor starts processing them. The flag can be combined with
WAIT_KILLABLE_RECV to defer non-fatal signals after receipt. Neither
supervisor-supplied errors nor the native syscall's restart behavior is
changed.

Nova exposes static information via its DRM_IOCTL_NOVA_INFO ioctl, thus
add vram_bar_size to struct drm_nova_info_gpu and remove
DRM_IOCTL_NOVA_GETPARAM and its uAPI definitions.
This breaks the uAPI, which is still fine at this point. It requires the
corresponding drm-test change in [1].

defined in Chapter 13 of the Wi-Fi Aware Specification v4.0.
Add NL80211_NAN_CAPA_INSTANT_COMM for drivers to advertise it. The
capability requires configurable synchronization support, and IC
requests are rejected if it isn't advertised.
When IC is enabled, user space must also configure the discovery
beacon interval. The IC schedule is expected to be configured

Currently we define btrfs_fs_info::qgroup_flags as u64, to match the
on-disk qgroup status item's flag.
But for now we have only 4 bits utilized for that flag, and since it's
u64 we have no way to properly use the existing atomic bit operations
(requires an unsigned long pointer).
This results in a lot of non-atomic operations inside qgroup code. Some
maybe fine as other locks are involved, but still it's not a good
practice.
Remove those non-atomic operations by:
- Re-define btrfs_fs_info::qgroup_flags as unsigned long
- Define BTRFS_QGROUP_STATUS_BIT_* and BTRFS_QGROUP_RUNTIME_BIT_*
Instead of the old value define the bit number.
- Use set_bit()/clear_bit()/test_bit() to replace open-coded bit
operations
- Add one extra check at qgroup status item read time
To make sure the on-disk flag is still inside ULONG_MAX.
Otherwise reject the status item and disable qgroup.
- Get rid of unnecessary spinlock when checking a single bit

CLOSE_RANGE_CLOEXEC marks a range close-on-exec. Nothing happens to
these fds unless an exec happens. Add CLOSE_RANGE_CLOEXEC_ONLY which
closes the close-on-exec file descriptors in the range.
When combined with CLOSE_RANGE_EXCEPT it names the close-on-exec file
descriptors that are supposed to survive. Every close-on-exec fd outside
of the range is closed. File descriptors without that flag are left
alone. Whatever the caller deliberately passes down, stdio, LISTEN_FDS,
an inherited pipe, remains where it is.
The handful of close-on-exec descriptors the caller still needs for the
exec such as the executable, an error pipe, sit in a specific range.
That is what a task between clone(CLONE_FILES) and execve() actually
wants:
clone(CLONE_FILES | CLONE_VM | CLONE_VFORK)
child: close_range(lo, hi, CLOSE_RANGE_UNSHARE |
CLOSE_RANGE_CLOEXEC_ONLY |
CLOSE_RANGE_EXCEPT)
child: rearrange descriptors in the now private table
child: execve()
Between the clone and the close_range() the child holds no reference of
its own on any file because copy_files() only bumps the fdtable
refcount. So a close() in the parent takes effect immediately. The
unshare also never takes a reference on the fds it leaves behind either.
The range is expressed in the parent's numbering. So a caller that
cannot name the file descriptors it keeps contiguously picks a range
wide enough to cover them, unshares, and tidies up with a second
close_range() on the table it now owns alone. That one is cheap. To keep
nothing, name a range that cannot hold an open descriptor, e.g.
close_range(~0U, ~0U, ...).
CLOSE_RANGE_CLOEXEC and CLOSE_RANGE_CLOEXEC_ONLY are mutually exclusive.

close_range() operates on [fd, max_fd]. Add CLOSE_RANGE_EXCEPT. This new
flag instructs it to operate on all file descriptors outside of the
range instead.
Without any other flags that means it closes everything except the file
descriptors in the specified range. Together with CLOSE_RANGE_CLOEXEC it
marks every file descriptor except the ones in the range as
close-on-exec. With CLOSE_RANGE_UNSHARE dup_fd() never takes a reference
on what is dropped.
A task between clone(CLONE_FILES | CLONE_VM | CLONE_VFORK) and execve()
that has the descriptors for the child in one window can shed the rest
of the shared table in one call:
close_range(lo, hi, CLOSE_RANGE_UNSHARE | CLOSE_RANGE_EXCEPT)
Nothing outside of the window is referenced by the child at any point.
