The CI has hit a couple of cases of:
RUN global.data_steal ...
tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1)
data_steal: Test terminated by timeout
FAIL global.data_steal
Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
to be causing issues in manual testing as well.

During raid resync, if a disk becomes faulty, the operation is
briefly interrupted. The MD_RECOVERY_RECOVER flag triggered by
the disk failure causes sync_action to incorrectly show "recover"
instead of "resync". The same issue affects reshape operations.
Reproduction steps:
mdadm -Cv /dev/md1 -l1 -n4 -e1.2 /dev/sd{a..d} // -> resync happened
mdadm -f /dev/md1 /dev/sda // -> resync interrupted
cat sync_action
-> recover
Add progress checks in md_sync_action() for resync/recover/reshape
to ensure the interface correctly reports the actual operation type.

commit 907a99c314a5 ("md: rename recovery_cp to resync_offset") replaces
recovery_cp with resync_offset in mdp_superblock_s which is in md_p.h.
md_p.h is used in userspace too. So mdadm building fails because of this.

The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.
Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.

support.
The cpufreq subsystem has a generic sysfs interface for controlling boost
(/sys/devices/system/cpu/cpufreq/boost).
The sysfs interface can be used to enable boost control from the cpupower
command on non-x86 platforms as well. So, allow boost controlling
on non-x86 system if boost sysfs file exists.
The set subcommand enables/disables the boost feature using the following
syntax:
cpupower set --boost 1
cpupower set --boost 0
The --boost option is an alias for --turbo-boost. We provided the neutral
option name because the name "turbo boost" is specific to Intel technology.
The frequency-info subcommand displays the enabled/disabled state of
the boost feature as follows:
boost state support:
Active: yes (or no)

This replaces devm_request_irq() with devm_request_threaded_irq().
On iMX93 11x11 EVK platform, the BT chip's BT_WAKE_OUT pin is connected
to an I2C GPIO expander instead of directly been connected to iMX GPIO.
When I2C GPIO expander's (PCAL6524) host driver receives an interrupt on
it's INTR line, the driver's interrupt handler needs to query the
interrupt source with PCAL6524 first, and then call the actual interrupt
handler, in this case the IRQ handler in BTNXPUART.
In order to handle interrupts when such I2C GPIO expanders are between
the host and interrupt source, devm_request_threaded_irq() is needed.
This commit also removes the IRQF_TRIGGER_FALLING flag, to allow setting
the IRQ trigger type from the device tree setting instead of hardcoding
in the driver.

BT_CODEC_TRANSPARENT in hci_enhanced_setup_sync(), which led to returning
success (0) instead of the negative error code (-EINVAL). However, the
result of hci_enhanced_setup_sync() seems to be ignored anyway, since NULL
gets passed to hci_cmd_sync_queue() as the last argument in that case and
the only function interested in that result is specified by that argument.

The leak occurs because pidfd_info() obtains a task_struct via
get_pid_task() but never calls put_task_struct() to drop the reference,
leaving task->usage unbalanced.
Fix the issue by adding '__free(put_task) = NULL' to the local variable

If all the subrequests in an unbuffered write stream fail, the subrequest
collector doesn't update the stream->transferred value and it retains its
initial LONG_MAX value. Unfortunately, if all active streams fail, then we
take the smallest value of { LONG_MAX, LONG_MAX, ... } as the value to set
in wreq->transferred - which is then returned from ->write_iter().
LONG_MAX was chosen as the initial value so that all the streams can be
quickly assessed by taking the smallest value of all stream->transferred -
but this only works if we've set any of them.
Fix this by adding a flag to indicate whether the value in
stream->transferred is valid and checking that when we integrate the
values. stream->transferred can then be initialised to zero.
This was found by running the generic/750 xfstest against cifs with
cache=none. It splices data to the target file. Once (if) it has used up
all the available scratch space, the writes start failing with ENOSPC.
This causes ->write_iter() to fail. However, it was returning
wreq->transferred, i.e. LONG_MAX, rather than an error (because it thought
the amount transferred was non-zero) and iter_file_splice_write() would
then try to clean up that amount of pipe bufferage - leading to an oops
when it overran. The kernel log showed:
CIFS: VFS: Send error in write = -28
followed by:
BUG: kernel NULL pointer dereference, address: 0000000000000008
with:
RIP: 0010:iter_file_splice_write+0x3a4/0x520

or:
RIP: 0010:pipe_buf_release (include/linux/pipe_fs_i.h:282)
iter_file_splice_write (fs/splice.c:755)
Also put a warning check into splice to announce if ->write_iter() returned
that it had written more than it was asked to.

In f07c7cc4684a, do_handle_open() was switched to use the automatic
cleanup method for getting a FD. In that change it was also switched
to pass O_CLOEXEC unconditionally to get_unused_fd_flags() instead
of passing the user-specified flags.
I don't see anything in that commit description that indicates this was
intentional, so I am assuming it was an oversight.
With this fix, the FD will again be opened with, or without, O_CLOEXEC
according to what the user requested.

BN == 0x00 in CIS Established means no isochronous data for the
corresponding direction (Core v6.1 pp. 2394). In this case SDU MTU
should be 0.
However, the specification does not say the Max_PDU_C_To_P or P_To_C are
then zero. Intel AX210 in Framed CIS mode sets nonzero Max_PDU for
direction with zero BN. This causes failure later when we try to LE
Setup ISO Data Path for disabled direction, which is disallowed (Core
v6.1 pp. 2750).
Fix by setting SDU MTU to 0 if BN == 0.

Calling pmu->start()/stop() on perf events in PERF_EVENT_STATE_OFF can
leave event->hw.idx at -1. When PMU drivers later attempt to use this
negative index as a shift exponent in bitwise operations, it leads to UBSAN
shift-out-of-bounds reports.
The issue is a logical flaw in how event groups handle throttling when some
members are intentionally disabled. Based on the analysis and the
reproducer provided by Mark Rutland (this issue on both arm64 and x86-64).
The scenario unfolds as follows:
1. A group leader event is configured with a very aggressive sampling
period (e.g., sample_period = 1). This causes frequent interrupts and
triggers the throttling mechanism.
2. A child event in the same group is created in a disabled state
(.disabled = 1). This event remains in PERF_EVENT_STATE_OFF.
Since it hasn't been scheduled onto the PMU, its event->hw.idx remains
initialized at -1.
3. When throttling occurs, perf_event_throttle_group() and later
perf_event_unthrottle_group() iterate through all siblings, including
the disabled child event.
4. perf_event_throttle()/unthrottle() are called on this inactive child
event, which then call event->pmu->start()/stop().
5. The PMU driver receives the event with hw.idx == -1 and attempts to
use it as a shift exponent. e.g., in macros like PMCNTENSET(idx),
leading to the UBSAN report.
The throttling mechanism attempts to start/stop events that are not
actively scheduled on the hardware.
Move the state check into perf_event_throttle()/perf_event_unthrottle() so
that inactive events are skipped entirely. This ensures only active events
with a valid hw.idx are processed, preventing undefined behavior and
silencing UBSAN warnings. The corrected check ensures true before
proceeding with PMU operations.
The problem can be reproduced with the syzkaller reproducer:
