Merge tag 'io_uring-6.12-20241101' of git://git.kernel.dk/linux

Pull io_uring fix from Jens Axboe:

 - Fix not honoring IOCB_NOWAIT for starting buffered writes in terms of
   calling sb_start_write(), leading to a deadlock if someone is
   attempting to freeze the file system with writes in progress, as each
   side will end up waiting for the other to make progress.

 * A fix to avoid compiler-insert library calls in the VDSO.
 * GCC+Rust builds have been disabled, to avoid issues related to ISA
   string mismatched between the GCC and LLVM Rust implementations.
 * The NX flag is now set in the EFI PE/COFF headers, which is necessary
   for some distro GRUB versions to boot images.
 * A fix to avoid leaking DT node reference counts on ACPI systems during
   cache info parsing.
 * CPU numbers are now printed as unsigned values during hotplug.
 * A pair of build fixes for usused macros, which can trigger warnings on
   some configurations.

Pull arm64 fixes from Will Deacon:
 "The important one is a change to the way in which we handle protection
  keys around signal delivery so that we're more closely aligned with
  the x86 behaviour, however there is also a revert of the previous fix
  to disable software tag-based KASAN with GCC, since a workaround
  materialised shortly afterwards.

  I'd love to say we're done with 6.12, but we're aware of some
  longstanding fpsimd register corruption issues that we're almost at
  the bottom of resolving.

   - Fix handling of POR_EL0 during signal delivery so that pushing the

7b83601da4 bcachefs fixes for 6.12-rc6 
Various syzbot fixes, and the more notable ones:
 
 - Fix for pointers in an extent overflowing the max (16) on a filesystem
   with many devices: we were creating too many cached copies when moving
   data around. Now, we only create at most one cached copy if there's a
   promote target set.
 
   Caching will be a bit broken for reflinked data until 6.13: I have
   larger series queued up which significantly improves the plumbing for
   data options down into the extent (bch_extent_rebalance) to fix this.
 
 - Fix for deadlock on -ENOSPC on tiny filesystems
 
   Allocation from the partial open_bucket list wasn't correctly
   accounting partial open_buckets as free: this fixes the main cause of
   tests timing out in the automated tests.

Merge tag 'bcachefs-2024-10-31' of git://evilpiepirate.org/bcachefs

Pull bcachefs fixes from Kent Overstreet:
 "Various syzbot fixes, and the more notable ones:

   - Fix for pointers in an extent overflowing the max (16) on a
     filesystem with many devices: we were creating too many cached
     copies when moving data around. Now, we only create at most one
     cached copy if there's a promote target set.

     Caching will be a bit broken for reflinked data until 6.13: I have
     larger series queued up which significantly improves the plumbing
     for data options down into the extent (bch_extent_rebalance) to fix
     this.

   - Fix for deadlock on -ENOSPC on tiny filesystems

     Allocation from the partial open_bucket list wasn't correctly
     accounting partial open_buckets as free: this fixes the main cause
     of tests timing out in the automated tests"

 Apart from this, there are fixes to address missing "arm" prefix in the

 but was identified when further additions to the same binding were

fa17cb4b3b tracing: Document tracefs gid mount option 
Commit ee7f366699 ("tracefs: Have new files inherit the ownership of
their parent") and commit 48b27b6b51 ("tracefs: Set all files to the
same group ownership as the mount option") introduced a new gid mount
option that allows specifying a group to apply to all entries in tracefs.

Document this in the tracing readme.

e4d32142d1 tracing: Fix tracefs mount options 
Commit 78ff640819 ("vfs: Convert tracefs to use the new mount API")
converted tracefs to use the new mount APIs caused mount options
(e.g. gid=<gid>) to not take effect.

The tracefs superblock can be updated from multiple paths:
    - on fs_initcall() to init_trace_printk_function_export()
    - from a work queue to initialize eventfs
      tracer_init_tracefs_work_func()
    - fsconfig() syscall to mount or remount of tracefs

The tracefs superblock root inode gets created early on in
init_trace_printk_function_export().

With the new mount API, tracefs effectively uses get_tree_single() instead
of the old API mount_single().

Previously, mount_single() ensured that the options are always applied to
the superblock root inode:
    (1) If the root inode didn't exist, call fill_super() to create it
        and apply the options.
    (2) If the root inode exists, call reconfigure_single() which
        effectively calls tracefs_apply_options() to parse and apply
        options to the subperblock's fs_info and inode and remount
        eventfs (if necessary)

On the other hand, get_tree_single() effectively calls vfs_get_super()
which:
    (3) If the root inode doesn't exists, calls fill_super() to create it
        and apply the options.
    (4) If the root inode already exists, updates the fs_context root
        with the superblock's root inode.

(4) above is always the case for tracefs mounts, since the super block's
root inode will already be created by init_trace_printk_function_export().

This means that the mount options get ignored:
    - Since it isn't applied to the superblock's root inode, it doesn't
      get inherited by the children.
    - Since eventfs is initialized from a separate work queue and
      before call to mount with the options, and it doesn't get remounted
      for mount.

Ensure that the mount options are applied to the super block and eventfs
is remounted to respect the mount options.

To understand this better, if fstab has the following:

 tracefs  /sys/kernel/tracing  tracefs   nosuid,nodev,noexec,gid=tracing 0  0

On boot up, permissions look like:

 # ls -l /sys/kernel/tracing/trace
 -rw-r----- 1 root root 0 Nov  1 08:37 /sys/kernel/tracing/trace

When it should look like:

 # ls -l /sys/kernel/tracing/trace
 -rw-r----- 1 root tracing 0 Nov  1 08:37 /sys/kernel/tracing/trace

d4148aeab4 mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes 
Since commit efa7df3e3b ("mm: align larger anonymous mappings on THP
boundaries") a mmap() of anonymous memory without a specific address hint
and of at least PMD_SIZE will be aligned to PMD so that it can benefit
from a THP backing page.

However this change has been shown to regress some workloads
significantly.  [1] reports regressions in various spec benchmarks, with
up to 600% slowdown of the cactusBSSN benchmark on some platforms.  The
benchmark seems to create many mappings of 4632kB, which would have merged
to a large THP-backed area before commit efa7df3e3b and now they are
fragmented to multiple areas each aligned to PMD boundary with gaps
between.  The regression then seems to be caused mainly due to the
benchmark's memory access pattern suffering from TLB or cache aliasing due
to the aligned boundaries of the individual areas.

Another known regression bisected to commit efa7df3e3b is darktable [2]
[3] and early testing suggests this patch fixes the regression there as
well.

To fix the regression but still try to benefit from THP-friendly anonymous
mapping alignment, add a condition that the size of the mapping must be a
multiple of PMD size instead of at least PMD size.  In case of many
odd-sized mapping like the cactusBSSN creates, those will stop being
aligned and with gaps between, and instead naturally merge again.

35e41024c4 vmscan,migrate: fix page count imbalance on node stats when demoting pages 
When numa balancing is enabled with demotion, vmscan will call
migrate_pages when shrinking LRUs.  migrate_pages will decrement the
the node's isolated page count, leading to an imbalanced count when
invoked from (MG)LRU code.

The result is dmesg output like such:

$ cat /proc/sys/vm/stat_refresh

[77383.088417] vmstat_refresh: nr_isolated_anon -103212
[77383.088417] vmstat_refresh: nr_isolated_file -899642

This negative value may impact compaction and reclaim throttling.

The following path produces the decrement:

shrink_folio_list
  demote_folio_list
    migrate_pages
      migrate_pages_batch
        migrate_folio_move
          migrate_folio_done
            mod_node_page_state(-ve) <- decrement

This path happens for SUCCESSFUL migrations, not failures.  Typically
callers to migrate_pages are required to handle putback/accounting for
failures, but this is already handled in the shrink code.

When accounting for migrations, instead do not decrement the count when
the migration reason is MR_DEMOTION.  As of v6.11, this demotion logic
is the only source of MR_DEMOTION.

0144c06c58 net: dpaa_eth: print FD status in CPU endianness in dpaa_eth_fd tracepoint 
Sparse warns:

note: in included file (through ../include/trace/trace_events.h,
../include/trace/define_trace.h,
../drivers/net/ethernet/freescale/dpaa/dpaa_eth_trace.h):
warning: incorrect type in assignment (different base types)
   expected unsigned int [usertype] fd_status
   got restricted __be32 const [usertype] status

We take struct qm_fd :: status, store it and print it as an u32,
though it is a big endian field. We should print the FD status in
CPU endianness for ease of debug and consistency between PowerPC and
Arm systems.

Though it is a not often used debug feature, it is best to treat it as
a bug and backport the format change to all supported stable kernels,
for consistency.

badccd49b9 net: enetc: set MAC address to the VF net_device 
The MAC address of VF can be configured through the mailbox mechanism of
ENETC, but the previous implementation forgot to set the MAC address in
net_device, resulting in the SMAC of the sent frames still being the old
MAC address. Since the MAC address in the hardware has been changed, Rx
cannot receive frames with the DMAC address as the new MAC address. The
most obvious phenomenon is that after changing the MAC address, we can
see that the MAC address of eno0vf0 has not changed through the "ifconfig
eno0vf0" command and the IP address cannot be obtained .

15cb732c16 sound fixes for 6.12-rc6 
Here we see slightly more commits than wished, but basically all are
 small and mostly trivial fixes.  The only core change is the
 workaround for __counted_by() usage in ASoC DAPM code, while the rest
 are device-specific fixes for Intel Baytrail devices, Cirrus and
 wcd937x codecs, and HD-audio / USB-audio devices.

3e8b7238b4 gpiolib: fix debugfs newline separators 
The gpiolib debugfs interface exports a list of all gpio chips in a
system and the state of their pins.

The gpio chip sections are supposed to be separated by a newline
character, but a long-standing bug prevents the separator from
being included when output is generated in multiple sessions, making the
output inconsistent and hard to read.

Make sure to only suppress the newline separator at the beginning of the
file as intended.

77b0d113ee btrfs: fix defrag not merging contiguous extents due to merged extent maps 
When running defrag (manual defrag) against a file that has extents that
are contiguous and we already have the respective extent maps loaded and
merged, we end up not defragging the range covered by those contiguous
extents. This happens when we have an extent map that was the result of
merging multiple extent maps for contiguous extents and the length of the
merged extent map is greater than or equals to the defrag threshold
length.

The script below reproduces this scenario:

   $ cat test.sh
   #!/bin/bash

   DEV=/dev/sdi
   MNT=/mnt/sdi

   mkfs.btrfs -f $DEV
   mount $DEV $MNT

   # Create a 256K file with 4 extents of 64K each.
   xfs_io -f -c "falloc 0 64K" \
             -c "pwrite 0 64K" \
             -c "falloc 64K 64K" \
             -c "pwrite 64K 64K" \
             -c "falloc 128K 64K" \
             -c "pwrite 128K 64K" \
             -c "falloc 192K 64K" \
             -c "pwrite 192K 64K" \
             $MNT/foo

   umount $MNT
   echo -n "Initial number of file extent items: "
   btrfs inspect-internal dump-tree -t 5 $DEV | grep EXTENT_DATA | wc -l

   mount $DEV $MNT
   # Read the whole file in order to load and merge extent maps.
   cat $MNT/foo > /dev/null

   btrfs filesystem defragment -t 128K $MNT/foo
   umount $MNT
   echo -n "Number of file extent items after defrag with 128K threshold: "
   btrfs inspect-internal dump-tree -t 5 $DEV | grep EXTENT_DATA | wc -l

   mount $DEV $MNT
   # Read the whole file in order to load and merge extent maps.
   cat $MNT/foo > /dev/null

   btrfs filesystem defragment -t 256K $MNT/foo
   umount $MNT
   echo -n "Number of file extent items after defrag with 256K threshold: "
   btrfs inspect-internal dump-tree -t 5 $DEV | grep EXTENT_DATA | wc -l

Running it:

   $ ./test.sh
   Initial number of file extent items: 4
   Number of file extent items after defrag with 128K threshold: 4
   Number of file extent items after defrag with 256K threshold: 4

The 4 extents don't get merged because we have an extent map with a size
of 256K that is the result of merging the individual extent maps for each
of the four 64K extents and at defrag_lookup_extent() we have a value of
zero for the generation threshold ('newer_than' argument) since this is a
manual defrag. As a consequence we don't call defrag_get_extent() to get
an extent map representing a single file extent item in the inode's
subvolume tree, so we end up using the merged extent map at
defrag_collect_targets() and decide not to defrag.

Fix this by updating defrag_lookup_extent() to always discard extent maps
that were merged and call defrag_get_extent() regardless of the minimum
generation threshold ('newer_than' argument).

A test case for fstests will be sent along soon.

a0f0625390 btrfs: fix extent map merging not happening for adjacent extents 
If we have 3 or more adjacent extents in a file, that is, consecutive file
extent items pointing to adjacent extents, within a contiguous file range
and compatible flags, we end up not merging all the extents into a single
extent map.

For example:

  $ mkfs.btrfs -f /dev/sdc
  $ mount /dev/sdc /mnt/sdc

  $ xfs_io -f -d -c "pwrite -b 64K 0 64K" \
                 -c "pwrite -b 64K 64K 64K" \
                 -c "pwrite -b 64K 128K 64K" \
                 -c "pwrite -b 64K 192K 64K" \
                 /mnt/sdc/foo

After all the ordered extents complete we unpin the extent maps and try
to merge them, but instead of getting a single extent map we get two
because:

1) When the first ordered extent completes (file range [0, 64K)) we
   unpin its extent map and attempt to merge it with the extent map for
   the range [64K, 128K), but we can't because that extent map is still
   pinned;

2) When the second ordered extent completes (file range [64K, 128K)), we
   unpin its extent map and merge it with the previous extent map, for
   file range [0, 64K), but we can't merge with the next extent map, for
   the file range [128K, 192K), because this one is still pinned.

   The merged extent map for the file range [0, 128K) gets the flag
   EXTENT_MAP_MERGED set;

3) When the third ordered extent completes (file range [128K, 192K)), we
   unpin its extent map and attempt to merge it with the previous extent
   map, for file range [0, 128K), but we can't because that extent map
   has the flag EXTENT_MAP_MERGED set (mergeable_maps() returns false
   due to different flags) while the extent map for the range [128K, 192K)
   doesn't have that flag set.

   We also can't merge it with the next extent map, for file range
   [192K, 256K), because that one is still pinned.

   At this moment we have 3 extent maps:

   One for file range [0, 128K), with the flag EXTENT_MAP_MERGED set.
   One for file range [128K, 192K).
   One for file range [192K, 256K) which is still pinned;

4) When the fourth and final extent completes (file range [192K, 256K)),
   we unpin its extent map and attempt to merge it with the previous
   extent map, for file range [128K, 192K), which succeeds since none
   of these extent maps have the EXTENT_MAP_MERGED flag set.

   So we end up with 2 extent maps:

   One for file range [0, 128K), with the flag EXTENT_MAP_MERGED set.
   One for file range [128K, 256K), with the flag EXTENT_MAP_MERGED set.

   Since after merging extent maps we don't attempt to merge again, that
   is, merge the resulting extent map with the one that is now preceding
   it (and the one following it), we end up with those two extent maps,
   when we could have had a single extent map to represent the whole file.

Fix this by making mergeable_maps() ignore the EXTENT_MAP_MERGED flag.
While this doesn't present any functional issue, it prevents the merging
of extent maps which allows to save memory, and can make defrag not
merging extents too (that will be addressed in the next patch).

c40dd8c473 bpf, test_run: Fix LIVE_FRAME frame update after a page has been recycled 
The test_run code detects whether a page has been modified and
re-initialises the xdp_frame structure if it has, using
xdp_update_frame_from_buff(). However, xdp_update_frame_from_buff()
doesn't touch frame->mem, so that wasn't correctly re-initialised, which
led to the pages from page_pool not being returned correctly. Syzbot
noticed this as a memory leak.

Fix this by also copying the frame->mem structure when re-initialising
the frame, like we do on initialisation of a new page from page_pool.

1d60d74e85 io_uring/rw: fix missing NOWAIT check for O_DIRECT start write 
When io_uring starts a write, it'll call kiocb_start_write() to bump the
super block rwsem, preventing any freezes from happening while that
write is in-flight. The freeze side will grab that rwsem for writing,
excluding any new writers from happening and waiting for existing writes
to finish. But io_uring unconditionally uses kiocb_start_write(), which
will block if someone is currently attempting to freeze the mount point.
This causes a deadlock where freeze is waiting for previous writes to
complete, but the previous writes cannot complete, as the task that is
supposed to complete them is blocked waiting on starting a new write.
This results in the following stuck trace showing that dependency with
the write blocked starting a new write:

Fix this by having the io_uring side honor IOCB_NOWAIT, and only attempt a
blocking grab of the super block rwsem if it isn't set. For normal issue
where IOCB_NOWAIT would always be set, this returns -EAGAIN which will
have io_uring core issue a blocking attempt of the write. That will in
turn also get completions run, ensuring forward progress.

Since freezing requires CAP_SYS_ADMIN in the first place, this isn't
something that can be triggered by a regular user.

fe05cee4d9 drm/xe: Don't short circuit TDR on jobs not started 
Short circuiting TDR on jobs not started is an optimization which is not
required. On LNL we are facing an issue where jobs do not get scheduled
by the GuC if it misses a GGTT page update. When this occurs let the TDR
fire, toggle the scheduling which may get the job unstuck, and print a
warning message. If the TDR fires twice on job that hasn't started,
timeout the job.

v2:
 - Add warning message (Paulo)
 - Add fixes tag (Paulo)
 - Timeout job which hasn't started after TDR firing twice
v3:
 - Include local change
v4:
 - Short circuit check_timeout on job not started
 - use warn level rather than notice (Paulo)

On LNL without a mmio read before a GGTT invalidate the GuC can
incorrectly read the GGTT scratch page upon next access leading to jobs

this. Since a GGTT invalidate is not a hot code path, blindly do a mmio
read before each GGTT invalidate.

d01661e1f4 kconfig: show sub-menu entries even if the prompt is hidden 
Since commit f79dc03fe6 ("kconfig: refactor choice value
calculation"), when EXPERT is disabled, nothing within the "if INPUT"
... "endif" block in drivers/input/Kconfig is displayed. This issue
affects all command-line interfaces and GUI frontends.

The prompt for INPUT is hidden when EXPERT is disabled. Previously,
menu_is_visible() returned true in this case; however, it now returns
false, resulting in all sub-menu entries being skipped.

Here is a simplified test case illustrating the issue:

    config A
           bool "A" if X
           default y

    config B
           bool "B"
           depends on A

When X is disabled, A becomes unconfigurable and is forced to y.
B should be displayed, as its dependency is met.

This commit restores the necessary code, so menu_is_visible() functions
as it did previously.

2ad7126c51 kbuild: deb-pkg: add pkg.linux-upstream.nokerneldbg build profile 
The Debian kernel supports the pkg.linux.nokerneldbg build profile.

The debug package tends to become huge, and you may not want to build
it even when CONFIG_DEBUG_INFO is enabled.

This commit introduces a similar profile for the upstream kernel.

e2c318225a kbuild: deb-pkg: add pkg.linux-upstream.nokernelheaders build profile 
Since commit f1d87664b8 ("kbuild: cross-compile linux-headers package
when possible"), 'make bindeb-pkg' may attempt to cross-compile the
linux-headers package, but it fails under certain circumstances.

For example, when CONFIG_MODULE_SIG_FORMAT is enabled on Debian, the
following command fails:

  $ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg
      [ snip ]

  compilation terminated.

This commit adds a new profile, pkg.linux-upstream.nokernelheaders, to
guard the linux-headers package.

There are two options to fix the above issue.

Option 1: Set the pkg.linux-upstream.nokernelheaders build profile

  $ DEB_BUILD_PROFILES=pkg.linux-upstream.nokernelheaders \
    make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg

This skips the building of the linux-headers package.

Option 2: Install the necessary build dependencies

If you want to cross-compile the linux-headers package, you need to
install additional packages.

For example, on Debian, the packages necessary for cross-compiling it
to arm64 can be installed with the following commands:

  # dpkg --add-architecture arm64
  # apt update
  # apt install gcc-aarch64-linux-gnu libssl-dev:arm64

cb08a02659 kbuild: rpm-pkg: disable kernel-devel package when cross-compiling 
Since commit f1d87664b8 ("kbuild: cross-compile linux-headers package
when possible"), 'make binrpm-pkg' may attempt to cross-compile the
kernel-devel package, but it fails under certain circumstances.

For example, when CONFIG_MODULE_SIG_FORMAT is enabled on openSUSE
Tumbleweed, the following command fails:

  $ make ARCH=arm64 CROSS_COMPILE=aarch64-suse-linux- binrpm-pkg
      [ snip ]

     25 | #include <openssl/opensslv.h>
        |          ^~~~~~~~~~~~~~~~~~~~

I believe this issue is less common on Fedora because the disto's cross-
compilier cannot link user-space programs. Hence, CONFIG_CC_CAN_LINK is
unset.

On Fedora 40, the package information explains this limitation clearly:

  $ dnf info gcc-aarch64-linux-gnu
      [ snip ]
  Description  : Cross-build GNU C compiler.
               :
               : Only building kernels is currently supported.  Support for cross-building
               : user space programs is not currently provided as that would massively multiply
               : the number of packages.

Anyway, cross-compiling RPM packages is somewhat challenging.

This commit disables the kernel-devel package when cross-compiling
because I did not come up with a better solution.

a14968aea6 gpio: fix uninit-value in swnode_find_gpio 
Fix an issue detected by the Smatch tool:

drivers/gpio/gpiolib-swnode.c:78 swnode_find_gpio() error:
uninitialized symbol 'ret'.

The issue occurs because the 'ret' variable may be used without
initialization if the for_each_gpio_property_name loop does not run.
This could lead to returning an undefined value, causing unpredictable
behavior.

Initialize 'ret' to 0 before the loop to ensure the function
returns an error code if no properties are parsed, maintaining proper
error handling.
