8c1b787938 f2fs: Create COW inode from parent dentry for atomic write
The i_pino in f2fs_inode_info has the previous parent's i_ino when inode
was renamed, which may cause f2fs_ioc_start_atomic_write to fail.
If file_wrong_pino is true and i_nlink is 1, then to find a valid pino,
we should refer to the dentry from inode.

To resolve this issue, let's get parent inode using parent dentry
directly.

4f5a100f87 f2fs: Require FMODE_WRITE for atomic write ioctls
The F2FS ioctls for starting and committing atomic writes check for
inode_owner_or_capable(), but this does not give LSMs like SELinux or
Landlock an opportunity to deny the write access - if the caller's FSUID
matches the inode's UID, inode_owner_or_capable() immediately returns true.

There are scenarios where LSMs want to deny a process the ability to write
particular files, even files that the FSUID of the process owns; but this
can currently partially be bypassed using atomic write ioctls in two ways:

 - F2FS_IOC_START_ATOMIC_REPLACE + F2FS_IOC_COMMIT_ATOMIC_WRITE can
   truncate an inode to size 0
 - F2FS_IOC_START_ATOMIC_WRITE + F2FS_IOC_ABORT_ATOMIC_WRITE can revert
   changes another process concurrently made to a file

Fix it by requiring FMODE_WRITE for these operations, just like for
F2FS_IOC_MOVE_RANGE. Since any legitimate caller should only be using these
ioctls when intending to write into the file, that seems unlikely to break
anything.

This reverts commit c550e25bca.

Commit c550e25bca ("f2fs: use flush

command to keep write order.

Since Commit dd291d77cc ("block:

0cac51185e f2fs: fix to avoid racing in between read and OPU dio write

In LFS mode, if there is inflight dio, let's wait for its completion,
this policy won't cover all race cases, however it is a tradeoff which
avoids abusing lock around IO paths.

aaf8c0b9ae f2fs: reduce expensive checkpoint trigger frequency
We may trigger high frequent checkpoint for below case:
1. mkdir /mnt/dir1; set dir1 encrypted
2. touch /mnt/file1; fsync /mnt/file1
3. mkdir /mnt/dir2; set dir2 encrypted
4. touch /mnt/file2; fsync /mnt/file2
...

Although, newly created dir and file are not related, due to
commit bbf156f7af ("f2fs: fix lost xattrs of directories"), we will
trigger checkpoint whenever fsync() comes after a new encrypted dir
created.

In order to avoid such performance regression issue, let's record an
entry including directory's ino in global cache whenever we update
directory's xattr data, and then triggerring checkpoint() only if
xattr metadata of target file's parent was updated.

This patch updates to cover below no encryption case as well:
1) parent is checkpointed
2) set_xattr(dir) w/ new xnid
3) create(file)
4) fsync(file)

In above cases racing in between atomic_write and GC, previous
data in atomic_file may be overwrited to cow_file, result in
data corruption.

This patch introduces PAGE_PRIVATE_ATOMIC_WRITE bit flag in page.private,
and use it to indicate that there is last dirty data in atomic file,
and the data should be writebacked into cow_file, if the flag is not
tagged in page, we should never write data across files.

8444ce5249 f2fs: add write priority option based on zone UFS
Currently, we are using a mix of traditional UFS and zone UFS to support
some functionalities that cannot be achieved on zone UFS alone. However,
there are some issues with this approach. There exists a significant
performance difference between traditional UFS and zone UFS. Under normal
usage, we prioritize writes to zone UFS. However, in critical conditions
(such as when the entire UFS is almost full), we cannot determine whether
data will be written to traditional UFS or zone UFS. This can lead to
significant performance fluctuations, which is not conducive to
development and testing. To address this, we have added an option
zlu_io_enable under sys with the following three modes:
1) zlu_io_enable == 0:Normal mode, prioritize writing to zone UFS;
2) zlu_io_enable == 1:Zone UFS only mode, only allow writing to zone UFS;
3) zlu_io_enable == 2:Traditional UFS priority mode, prioritize writing to
traditional UFS.

Booting with the 'profile=sleep' kernel command line option added or

  # echo -n sleep > /sys/kernel/profiling

after boot causes the system to lock up.

Lockdep reports

  kthreadd/3 is trying to acquire lock:
  ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: get_wchan+0x32/0x70

  but task is already holding lock:
  ffff93ac82e08d58 (&p->pi_lock){....}-{2:2}, at: try_to_wake_up+0x53/0x370

with the call trace being

   lock_acquire+0xc8/0x2f0

let's remove 'profile=sleep' support based on the assumption that nobody

a5dbd76a89 X86 fixes:
- Prevent a deadlock on cpu_hotplug_lock in the aperf/mperf driver.
 
       A recent change in the ACPI code which consolidated code pathes moved
       the invocation of init_freq_invariance_cppc() to be moved to a CPU
       hotplug handler. The first invocation on AMD CPUs ends up enabling a
       static branch which dead locks because the static branch enable tries to
       acquire cpu_hotplug_lock but that lock is already held write by the
       hotplug machinery.
 
       Use static_branch_enable_cpuslocked() instead and take the hotplug
       lock read for the Intel code path which is invoked from the
       architecture code outside of the CPU hotplug operations.
 
     - Fix the number of reserved bits in the sev_config structure bit field
       so that the bitfield does not exceed 64 bit.
 
     - Add missing Zen5 model numbers
 
     - Fix the alignment assumptions of pti_clone_pgtable() and
       clone_entry_text() on 32-bit:
 
       The code assumes PMD aligned code sections, but on 32-bit the kernel
       entry text is not PMD aligned. So depending on the code size and
       location, which is configuration and compiler dependent, entry text
       can cross a PMD boundary. As the start is not PMD aligned adding PMD
       size to the start address is larger than the end address which
       results in partially mapped entry code for user space. That causes
       endless recursion on the first entry from userspace (usually #PF).
 
       Cure this by aligning the start address in the addition so it ends up
       at the next PMD start address.
 
       clone_entry_text() enforces PMD mapping, but on 32-bit the tail might
       eventually be PTE mapped, which causes a map fail because the PMD for
       the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for
       the clone() invocation which resolves to PTE on 32-bit and PMD on
       64-bit.
 
     - Zero the 8-byte case for get_user() on range check failure on 32-bit
 
       The recend consolidation of the 8-byte get_user() case broke the
       zeroing in the failure case again. Establish it by clearing ECX
       before the range check and not afterwards as that obvioulsy can't be
       reached when the range check fails

   size to the start address is larger than the end address which
   results in partially mapped entry code for user space. That causes
   endless recursion on the first entry from userspace (usually #PF).

   Cure this by aligning the start address in the addition so it ends up
   at the next PMD start address.

   clone_entry_text() enforces PMD mapping, but on 32-bit the tail might
   eventually be PTE mapped, which causes a map fail because the PMD for
   the tail is not a large page mapping. Use PTI_LEVEL_KERNEL_IMAGE for
   the clone() invocation which resolves to PTE on 32-bit and PMD on
   64-bit.

 - Zero the 8-byte case for get_user() on range check failure on 32-bit

   The recend consolidation of the 8-byte get_user() case broke the
   zeroing in the failure case again. Establish it by clearing ECX
   before the range check and not afterwards as that obvioulsy can't be
   reached when the range check fails

61ca6c7829 Two fixes for the timer/clocksource code:
- The recent fix for making the take over of the broadcast timer more
       reliable retrieves a per CPU pointer in preemptible context.
       This went unnoticed in testing as some compilers hoist the access into
       the non-preemotible section where the pointer is actually used, but
       obviously compilers can rightfully invoke it where the code put it.
 
       Move it into the non-preemptible section right to the actual usage
       side to cure it.
 
     - The clocksource watchdog is supposed to emit a warning when the retry
       count is greater than one and the number of retries reaches the
       limit. The condition is backwards and warns always when the count is
       greater than one. Fixup the condition to prevent spamming dmesg.

Commit 04f08ef291 ("arm/arm64: dts: arm: Use generic clock and
regulator nodenames") renamed nodes and created 2 "clock-24000000" nodes
(at different paths).

The kernel can't handle these duplicate names even though they are at
different paths.  Fix this by renaming one of the nodes to "clock-pclk".

This name is aligned with other Arm boards (those didn't have a known
frequency to use in the node name).

b6547e5486 runtime constants: deal with old decrepit linkers
The runtime constants linker script depended on documented linker
behavior [1]:

 "If an output section’s name is the same as the input section’s name
  and is representable as a C identifier, then the linker will
  automatically PROVIDE two symbols: __start_SECNAME and __stop_SECNAME,
  where SECNAME is the name of the section. These indicate the start
  address and end address of the output section respectively"

to just automatically define the symbol names for the bounds of the
runtime constant arrays.

It turns out that this isn't actually something we can rely on, with old
linkers not generating these automatic symbols.  It looks to have been
introduced in binutils-2.29 back in 2017, and we still support building
with versions all the way back to binutils-2.25 (from 2015).

And yes, Oleg actually seems to be using such ancient versions of
binutils.

So instead of depending on the implicit symbols from "section names
match and are representable C identifiers", just do this all manually.
It's not like it causes us any extra pain, we already have to do that
for all the other sections that we use that often have special
characters in them.

Merge tag 'riscv-for-linus-6.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:

 - A fix to avoid dropping some of the internal pseudo-extensions, which
   breaks *envcfg dependency parsing

 - The kernel entry address is now aligned in purgatory, which avoids a
   misaligned load that can lead to crash on systems that don't support
   misaligned accesses early in boot

 - The FW_SFENCE_VMA_RECEIVED perf event was duplicated in a handful of
   perf JSON configurations, one of them been updated to
   FW_SFENCE_VMA_ASID_SENT

 - The starfive cache driver is now restricted to 64-bit systems, as it
   isn't 32-bit clean

 - A fix for to avoid aliasing legacy-mode perf counters with software
   perf counters

 - VM_FAULT_SIGSEGV is now handled in the page fault code

 - A fix for stalls during CPU hotplug due to IPIs being disabled

 - A fix for memblock bounds checking. This manifests as a crash on
   systems with discontinuous memory maps that have regions that don't
   fit in the linear map

f2655ac2c0 clocksource: Fix brown-bag boolean thinko in cs_watchdog_read()
The current "nretries > 1 || nretries >= max_retries" check in
cs_watchdog_read() will always evaluate to true, and thus pr_warn(), if
nretries is greater than 1.  The intent is instead to never warn on the
first try, but otherwise warn if the successful retry was the last retry.

Therefore, change that "||" to "&&".
