Namhyung Kim reported:
I've updated the perf-tools-next to v6.16-rc1 and found a build error
like below on alpine linux 3.18.
In file included from bench/futex.c:6:
/usr/include/sys/prctl.h:88:8: error: redefinition of 'struct prctl_mm_map'
88 | struct prctl_mm_map {
| ^~~~~~~~~~~~
In file included from bench/futex.c:5:
/linux/tools/include/uapi/linux/prctl.h:134:8: note: originally defined here
134 | struct prctl_mm_map {
| ^~~~~~~~~~~~
make[4]: *** [/linux/tools/build/Makefile.build:86: /build/bench/futex.o] Error 1
git bisect says it's the first commit introduced the failure.
So both /usr/include/sys/prctl.h and /linux/tools/include/uapi/linux/prctl.h
provide struct prctl_mm_map but their include guard must be different.
/usr/include/sys/prctl.h provided by glibc contains the
prctl() declaration. It includes also linux/prctl.h.
The /usr/include/sys/prctl.h on alpine linux is different. This is
probably coming from musl. It contains the PR_* definition and the
prctl() declaration. So it clashes here because now the one struct is
available twice.
The man page for prctl(2) says:
| #include <linux/prctl.h> /* Definition of PR_* constants */
| #include <sys/prctl.h>
so musl doesn't follow this.
So don't include linux/prctl.h explicitely and add some new defines
needed if they aren't available.

The bug only appears when:
- windows 11 copies a file that has an alternate data stream
- streams_xattr is enabled on the share configuration.
Microsoft Edge adds a ZoneIdentifier data stream containing the URL
for files it downloads.
Another way to create a test file:
- open cmd.exe
- echo "hello from default data stream" > hello.txt
- echo "hello again from ads" > hello.txt:ads.txt
If you open the file using notepad, we'll see the first message.
If you run "notepad hello.txt:ads.txt" in cmd.exe, we should see
the second message.
dir /s /r should least all streams for the file.
The truncation happens because the windows 11 client sends
a SetInfo/EndOfFile message on the ADS, but it is instead applied
on the main file, because we don't check fp->stream.
When receiving set/get info file for a stream file, Change to process
requests using stream position and size.
Truncate is unnecessary for stream files, so we skip
set_file_allocation_info and set_end_of_file_info operations.

If client set ->PreviousSessionId on kerberos session setup stage,
NULL pointer dereference error will happen. Since sess->user is not
set yet, It can pass the user argument as NULL to destroy_previous_session.
sess->user will be set in ksmbd_krb5_authenticate(). So this patch move
calling destroy_previous_session() after ksmbd_krb5_authenticate().

It is very useful to find driver implementing compatibles with `git grep

The Elan eKTH8D18 touchscreen controller is an I2C HID device with a
longer boot-up time. Power sequence timing wise it is compatible with
the eKTH6A12NAY, with a power-on delay of at least 5ms, 20ms
out-of-reset for I2C ack response, and 150ms out-of-reset for I2C HID
enumeration, both shorter than what the eKTH6A12NAY requires.
Enumeration and subsequent operation follows the I2C HID standard.
Add a compatible string for it with the ekth6a12nay one as a fallback.
No enum was used as it is rare to actually add new entries. These
chips are commonly completely backward compatible, and unless the
power sequencing delays change, there is no real effort being made to
keep track of new parts, which come out constantly.
Also drop the constraints on the I2C address since it's not really
part of the binding.

Add missing close() to avoid leaking perf events.
In past perfs this mattered little as the function was just used by 'perf
list'.
As the function is now used to detect hybrid PMUs leaking the perf event
is somewhat more painful.

Now when isolcpus is enabled via the cmdline, wq_isolated_cpumask does
not include these isolated CPUs, even wq_unbound_cpumask has already
excluded them. It is only when we successfully configure an isolate cpuset
partition that wq_isolated_cpumask gets overwritten by
workqueue_unbound_exclude_cpumask(), including both the cmdline-specified
isolated CPUs and the isolated CPUs within the cpuset partitions.
Fix this issue by initializing wq_isolated_cpumask properly in
workqueue_init_early().

sched_create_group()
During task_group creation, sched_create_group() calls
scx_group_set_weight() with CGROUP_WEIGHT_DFL to initialize the sched_ext
portion. This is premature and ends up calling ops.cgroup_set_weight() with
an incorrect @cgrp before ops.cgroup_init() is called.
sched_create_group() should just initialize SCX related fields in the new
task_group. Fix it by factoring out scx_tg_init() from sched_init() and
making sched_create_group() call that function instead of
scx_group_set_weight().

to build failures on !CONFIG_GROUP_SCHED configs.

check_directory_structure runs after check_dirents, so it expects that
it won't see any inodes with missing backpointers - normally.
But online fsck can't run check_dirents yet, or the user might only be
running a specific pass, so we need to be careful that this isn't an
error. If an inode is unreachable, that's handled by a separate pass.
Also, add a new 'bch2_inode_has_backpointer()' helper, since we were
doing this inconsistently.

On some systems with Nahum 11 and Nahum 13 the value of the XTAL clock in
the software STRAP is incorrect. This causes the PTP timer to run at the
wrong rate and can lead to synchronization issues.
The STRAP value is configured by the system firmware, and a firmware
update is not always possible. Since the XTAL clock on these systems
always runs at 38.4MHz, the driver may ignore the STRAP and just set
the correct value.

This patch fixes an issue seen in a large-scale deployment under heavy
incoming pkts where the aRFS flow wrongly matches a flow and reprograms the
NIC with wrong settings. That mis-steering causes RX-path latency spikes
and noisy neighbor effects when many connections collide on the same
hash (some of our production servers have 20-30K connections).
set_rps_cpu() calls ndo_rx_flow_steer() with flow_id that is calculated by
hashing the skb sized by the per rx-queue table size. This results in
multiple connections (even across different rx-queues) getting the same
hash value. The driver steer function modifies the wrong flow to use this
rx-queue, e.g.: Flow#1 is first added:
Flow#1: <ip1, port1, ip2, port2>, Hash 'h', q#10
Later when a new flow needs to be added:
Flow#2: <ip3, port3, ip4, port4>, Hash 'h', q#20
The driver finds the hash 'h' from Flow#1 and updates it to use q#20. This
results in both flows getting un-optimized - packets for Flow#1 goes to
q#20, and then reprogrammed back to q#10 later and so on; and Flow #2
programming is never done as Flow#1 is matched first for all misses. Many
flows may wrongly share the same hash and reprogram rules of the original
flow each with their own q#.
Tested on two 144-core servers with 16K netperf sessions for 180s. Netperf
clients are pinned to cores 0-71 sequentially (so that wrong packets on q#s
72-143 can be measured). IRQs are set 1:1 for queues -> CPUs, enable XPS,
enable aRFS (global value is 144 * rps_flow_cnt).
Test notes about results from ice_rx_flow_steer():

1. "Skip:" counter increments here:
if (fltr_info->q_index == rxq_idx ||
arfs_entry->fltr_state != ICE_ARFS_ACTIVE)

2. "Add:" counter increments here:
ret = arfs_entry->fltr_info.fltr_id;
INIT_HLIST_NODE(&arfs_entry->list_entry);
3. "Update:" counter increments here:
/* update the queue to forward to on an already existing flow */
Runtime comparison: original code vs with the patch for different
rps_flow_cnt values.
+-------------------------------+--------------+--------------+
| rps_flow_cnt | 512 | 2048 |
+-------------------------------+--------------+--------------+
| Ratio of Pkts on Good:Bad q's | 214 vs 822K | 1.1M vs 980K |

A separate TCP_STREAM and TCP_RR with 1,4,8,16,64,128,256,512 connections
showed no performance degradation.
Some points on the patch/aRFS behavior:
1. Enabling full tuple matching ensures flows are always correctly matched,
even with smaller hash sizes.
2. 5-6% drop in CPU utilization as the packets arrive at the correct CPUs
and fewer calls to driver for programming on misses.
3. Larger hash tables reduces mis-steering due to more unique flow hashes,
but still has clashes. However, with larger per-device rps_flow_cnt, old
flows take more time to expire and new aRFS flows cannot be added if h/w
limits are reached (rps_may_expire_flow() succeeds when 10*rps_flow_cnt
pkts have been processed by this cpu that are not part of the flow).

PERCPU_MODULE_RESERVE defines the maximum size that can by used for the

Commit 035fcdc4d240c ("openvswitch: Merge three per-CPU structures into

moved the separate alloc_percpu() invocations at module init time to a
static per-CPU variable which is allocated by the module loader.
The size of the per-CPU data section for openvswitch is 6488 bytes which
is ~80% of the available per-CPU memory. Together with a few other
modules it is easy to exhaust the available 8KiB of memory.

io_sq_thread() will notice that the tctx did not get setup and hence it

Without explicitly setting a parent for the watchdog device, the device is
registered with a NULL parent. This causes device_add() (called internally
by devm_watchdog_register_device()) to register the device under
/sys/devices/virtual, since no parent is provided. The result is:
DEVPATH=/devices/virtual/watchdog/watchdog0
To fix this, assign &pdev->dev as the parent of the watchdog device before
calling devm_watchdog_register_device(). This ensures the device is
associated with the Portwell EC platform device and placed correctly in
sysfs as:
DEVPATH=/devices/platform/portwell-ec/watchdog/watchdog0
This aligns the device hierarchy with expectations and avoids misplacement
under the virtual class.

An aoe device's rq_list contains accepted block requests that are
waiting to be transmitted to the aoe target. This queue was added as

when an aoe device is downed which caused blk_mq_freeze_queue() to sleep
indefinitely waiting for those requests to complete, causing a hang. This
fix cleans out the queue before calling blk_mq_freeze_queue().

Commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still
active") ensured that active jobs are returned to the pending list when
extending the timeout. However, it didn't use the pending list's lock to
manipulate the list, which causes a race condition as the scheduler's
workqueues are running.
Hold the lock while manipulating the scheduler's pending list to prevent
a race.

A path exists in a particular snapshot: we should do the pathwalk in the
snapshot ID of the inode we started from, _not_ change snapshot ID as we
walk inodes and dirents.

We can easily go from inode number -> path now, which makes for more
useful log messages.
