ovl: fix failed copyup of fileattr on a symlink
Some local filesystems support setting persistent fileattr flags
(e.g. FS_NOATIME_FL) on directories and regular files via ioctl.
Some of those persistent fileattr flags are reflected to vfs as
in-memory inode flags (e.g. S_NOATIME).
Overlayfs uses the in-memory inode flags (e.g. S_NOATIME) on a lower file
as an indication that a the lower file may have persistent inode fileattr
flags (e.g. FS_NOATIME_FL) that need to be copied to upper file.
However, in some cases, the S_NOATIME in-memory flag could be a false
indication for persistent FS_NOATIME_FL fileattr. For example, with NFS
and FUSE lower fs, as was the case in the two bug reports, the S_NOATIME
flag is set unconditionally for all inodes.
Users cannot set persistent fileattr flags on symlinks and special files,
but in some local fs, such as ext4/btrfs/tmpfs, the FS_NOATIME_FL fileattr
flag are inheritted to symlinks and special files from parent directory.
In both cases described above, when lower symlink has the S_NOATIME flag,
overlayfs will try to copy the symlink's fileattrs and fail with error
ENOXIO, because it could not open the symlink for the ioctl security hook.
To solve this failure, do not attempt to copyup fileattrs for anything
other than directories and regular files.

f2fs update for 6.6-rc1
In this cycle, we don't have a highlighted feature enhancement, but mostly have fixed issues mainly in two parts: 1) zoned block device, 2) compression support. For zoned block device, we've tried to improve the power-off recovery flow as much as possible. For compression, we found some corner cases caused by wrong compression policy and logics. Other than them, there were some reverts and stat corrections. Bug fix: - use finish zone command when closing a zone - check zone type before sending async reset zone command - fix to assign compress_level for lz4 correctly - fix error path of f2fs_submit_page_read() - don't {,de}compress non-full cluster - send small discard commands during checkpoint back - flush inode if atomic file is aborted - correct to account gc/cp stats And, there are minor bug fixes, avoiding false lockdep warning, and clean-ups. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmTyemoACgkQQBSofoJI UNLLKQ//bupYGPOqAgKbd/s7FhtULMiiRmFVy7W2eoMIc/oeeXOGrzDAF/1NifLC WLV4uBNVTS4PS8D1vRzxZNEZt9aqPS0vQ8hxW/3nTI9Z425NX3nz7gLSxxmwIkIe xj++V6tvKPcCH0BfKvfFCtcxj09PsflgdEuT8w/sIkH6p4o+VEMFs1Lc9PQsjUmh epznK7JGBwpAxmHqI74n1eAw2CI6W+oKx23YDTNMBD6hmXTU0fkTeBURrOlSsUHZ nhafPecsrCEI+OpAj03G/7e/zt+iTUKdmHx9O5ir/P00vF/c+SU2vSwB97FiHqBi B4UmocTM0MAsU80PQcmE6aU3zgQFI0Yun5yZ24VeWjKTu76ssZSmT2HA/4RL+LLf AeAW4FSyfh76pls8X5IWfilxGLWq6kTzSZA0MF7dH2q7qlj5apL5wKpm/XH6POqn qELY/Y9+P1QuCcNL8BiYrgA5xBqVJ7Uw/6/6U3Y77PElc+Pwl3vI8UZ7uCOBrsXL e0TLXy23AJA6AS2DyLLziy669nXAZRb95B8TWMfEeVZIMFvCeeqYc74N8jOFa0T8 q6uQFZs+0cETLZA8MSZdlNhzvhJmbW6wgSIz++CEdikWSLBZMKWxBVjCPkkCY9uc DMh8zruSVbYPZWBTcxkMFEBJKKrU43++e7pb8ZoqTj4Pq1317b0= =Qa8+ -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6-6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this cycle, we don't have a highlighted feature enhancement, but mostly have fixed issues mainly in two parts: 1) zoned block device, and 2) compression support.

cgroup: fix build when CGROUP_SCHED is not enabled
Sudip Mukherjee reports that the mips sb1250_swarm_defconfig build fails
with the current kernel. It isn't actually MIPS-specific, it's just
that that defconfig does not have CGROUP_SCHED enabled like most configs
do, and as such shows this error:
kernel/cgroup/cgroup.c: In function 'cgroup_local_stat_show':
kernel/cgroup/cgroup.c:3699:15: error: implicit declaration of function 'cgroup_tryget_css'; did you mean 'cgroup_tryget'? [-Werror=implicit-function-declaration]
3699 | css = cgroup_tryget_css(cgrp, ss);
| ^~~~~~~~~~~~~~~~~
| cgroup_tryget
kernel/cgroup/cgroup.c:3699:13: warning: assignment to 'struct cgroup_subsys_state *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
3699 | css = cgroup_tryget_css(cgrp, ss);
| ^
because cgroup_tryget_css() only exists when CGROUP_SCHED is enabled,
and the cgroup_local_stat_show() function should similarly be guarded by
that config option.
Move things around a bit to fix this all.

tracing: Zero the pipe cpumask on alloc to avoid spurious -EBUSY
The pipe cpumask used to serialize opens between the main and percpu
trace pipes is not zeroed or initialized. This can result in
spurious -EBUSY returns if underlying memory is not fully zeroed.
This has been observed by immediate failure to read the main
trace_pipe file on an otherwise newly booted and idle system:
# cat /sys/kernel/debug/tracing/trace_pipe
cat: /sys/kernel/debug/tracing/trace_pipe: Device or resource busy
Zero the allocation of pipe_cpumask to avoid the problem.

tracing: Replace strlcpy with strscpy in trace/events/task.h
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

Warning happened in rb_end_commit() at code:

It is because the race between writing event into cpu buffer and swapping
cpu buffer through file per_cpu/cpu0/snapshot:
Write on CPU 0 Swap buffer by per_cpu/cpu0/snapshot on CPU 1
-------- --------

[...]

[...]
cpu_buffer = buffer->buffers[cpu]; // 5. Now find 'cpu_buffer_b' !!!
rb_commit(cpu_buffer)
rb_end_commit() // 6. WARN for the wrong 'committing' state !!!
Based on above analysis, we can easily reproduce by following testcase:
``` bash
#!/bin/bash
dmesg -n 7
sysctl -w kernel.panic_on_warn=1
TR=/sys/kernel/tracing
echo 7 > ${TR}/buffer_size_kb
echo "sched:sched_switch" > ${TR}/set_event
while [ true ]; do
echo 1 > ${TR}/per_cpu/cpu0/snapshot
done &
while [ true ]; do
echo 1 > ${TR}/per_cpu/cpu0/snapshot
done &
while [ true ]; do
echo 1 > ${TR}/per_cpu/cpu0/snapshot
done &
```
To fix it, IIUC, we can use smp_call_function_single() to do the swap on
the target cpu where the buffer is located, so that above race would be
avoided.

Tracing updates for 6.6:
User visible changes: - Added a way to easier filter with cpumasks: # echo 'cpumask & CPUS{17-42}' > /sys/kernel/tracing/events/ipi_send_cpumask/filter - Show actual size of ring buffer after modifying the ring buffer size via buffer_size_kb. Currently it just returns what was written, but the actual size rounds up to the sub buffer size. Show that real size instead. Major changes: - Added "eventfs". This is the code that handles the inodes and dentries of tracefs/events directory. As there are thousands of events, and each event has several inodes and dentries that currently exist even when tracing is never used, they take up precious memory. Instead, eventfs will allocate the inodes and dentries in a JIT way (similar to what procfs does). There is now metadata that handles the events and subdirectories, and will create the inodes and dentries when they are used.

workqueue: Changes for v6.6
* Unbound workqueues now support more flexible affinity scopes. The default behavior is to soft-affine according to last level cache boundaries. A work item queued from a given LLC is executed by a worker running on the same LLC but the worker may be moved across cache boundaries as the scheduler sees fit. On machines which multiple L3 caches, which are becoming more popular along with chiplet designs, this improves cache locality while not harming work conservation too much. Unbound workqueues are now also a lot more flexible in terms of execution affinity. Differeing levels of affinity scopes are supported and both the default and per-workqueue affinity settings can be modified dynamically. This should help working around amny of sub-optimal behaviors observed recently with asymmetric ARM CPUs. This involved signficant restructuring of workqueue code. Nothing was reported yet but there's some risk of subtle regressions. Should keep an eye out. * Rescuer workers now has more identifiable comms. * workqueue.unbound_cpus added so that CPUs which can be used by workqueue can be constrained early during boot. * Now that all the in-tree users have been flushed out, trigger warning if system-wide workqueues are flushed. * One pull commit from for-6.5-fixes to avoid cascading conflicts in the affinity scope patchset. -----BEGIN PGP SIGNATURE----- iIQEABYIACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZPERlQ4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGVqQAPwIOy9tWY5jFAmMuIyH6wV50hbmfxCc2n5xhQNr 5HoyGgEA8lw1W7afDCIPiQVA7AYsu8dhwuNSOcRCJxhrrn4XsA0= =g/Uu -----END PGP SIGNATURE----- Merge tag 'wq-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue updates from Tejun Heo: - Unbound workqueues now support more flexible affinity scopes.

cgroup: Changes for v6.6
* Per-cpu cpu usage stats are now tracked. This currently isn't printed out
in the cgroupfs interface and can only be accessed through e.g. BPF.
Should decide on a not-too-ugly way to show per-cpu stats in cgroupfs.
* cpuset received some cleanups and prepatory patches for the pending
cpus.exclusive patchset which will allow cpuset partitions to be created
below non-partition parents, which should ease the management of partition
cpusets.
* A lot of code and documentation cleanup patches.
* tools/testing/selftests/cgroup/test_cpuset.c is added. This causes trivial
conflicts in .gitignore and Makefile under the directory against

selftests/x86: Update map_shadow_stack syscall nr
Shadow stack's selftest utilizes the map_shadow_stack syscall. The
syscall is new with the feature, but the selftests cannot automatically
find the headers for the kernel source tree they are located in. This
resulted in the shadow stack test failing to build until the brand new
headers were installed.
To avoid this, a copy of the new uapi defines needed by the test were
included in the selftest (see link for discussion). When shadow stack was
merged the syscall number was changed, but the copy in the selftest was
not updated.
So update the copy of the syscall number define used when the required
headers are not installed, to have the final syscall number from the
merge.

Here is the big set of tty and serial driver changes for 6.6-rc1. Lots of cleanups in here this cycle, and some driver updates. Short summary is: - Jiri's continued work to make the tty code and apis be a bit more sane with regards to modern kernel coding style and types - cpm_uart driver updates - n_gsm updates and fixes - meson driver updates - sc16is7xx driver updates - 8250 driver updates for different hardware types - qcom-geni driver fixes - tegra serial driver change - stm32 driver updates - synclink_gt driver cleanups - tty structure size reduction All of these have been in linux-next this week with no reported issues.

NFSD 6.6 Release Notes
I'm thrilled to announce that the Linux in-kernel NFS server now offers NFSv4 write delegations. A write delegation enables a client to cache data and metadata for a single file more aggressively, reducing network round trips and server workload. Many thanks to Dai Ngo for contributing this facility, and to Jeff Layton and Neil Brown for reviewing and testing it. This release also sees the removal of all support for DES- and triple-DES-based Kerberos encryption types in the kernel's SunRPC implementation. These encryption types have been deprecated by the Internet community for years and are considered insecure. This change affects both the in-kernel NFS client and server. The server's UDP and TCP socket transports have now fully adopted David Howells' new bio_vec iterator so that no more than one sendmsg() call is needed to transmit each RPC message. In particular, this helps kTLS optimize record boundaries when sending RPC-with-TLS replies, and it takes the server a baby step closer to handling file I/O via folios. We've begun work on overhauling the SunRPC thread scheduler to remove a costly linked-list walk when looking for an idle RPC service thread to wake. The pre-requisites are included in this release. Thanks to Neil Brown for his ongoing work on this improvement. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmTwoa0ACgkQM2qzM29m f5cZvw/8CmFVNC27aMrJEhRRhwwrXbLzUkWh9GCYkG98PHYiLxLTvZ6qELXAax/a UjSgIDSRcWl4z8M/tyBQtgsw7NADr+7XWqEoXR7HZ5pEEC/KNGM0oQWQ92ojjKYy JmHdB02uaDJfcd9ioFTU13cw7q2BQfoe2xLI8yqis2vcVSu92AM7aIw+cvJIpwQB inA3TIIsYTV/gPByXSfEtvmYACadoFiMvfvYwaWhjFS9MdSzFmcVG0Dp3EFIig29 odmWEofcz6uIvUWvUswWEGdoSu7uOKIztSuAI4PlTwaofUaSKG6e5kmtpr3cLERD Uhg2lm5JgqkXBd7QHObNimJ4DtQzFwHmhA08qo8rd/zba75mn/Hr5IF0q3Rxs99J SRYHcAeP8afKn5Ge0yzoTgCNcqhfz8KLRfoCQX49mljr+muNxld4nMklD2KdUwJi XEB512/q3E4nUgopXZiSJYQYAq1CfdR5WpGipZ9X0XK9HZBDF/qhXGtk1YQuNWyj ZxJS3bfBza4oVIvP5/ehjCIQwOvqkcrC5zZGDIgDvw9Q6L3L1wqmVntsdCLCLRcJ jB4IOsj+DECfJ6w2vP2SZ3GeMtFnyuTQjhUTkjPuAKTBBiKo4Tj0o/agpfDYbWZy 1l3a2yH5jqJgkm4MaVh3YHRJGc0ub0ccpIrs3QQ4jvjMLQ/3Gcs= =XGHs -----END PGP SIGNATURE----- Merge tag 'nfsd-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "I'm thrilled to announce that the Linux in-kernel NFS server now offers NFSv4 write delegations.

fbdev: ssd1307fb: Use bool for ssd1307fb_deviceinfo flags
The .need_pwm and .need_chargepump fields in struct ssd1307fb_deviceinfo are flags that can have only two possible values: 0 and 1. Reduce kernel size by changing their types from int to bool.
