Updates for the X86 APIC:
- Make the quirk for non-maskable MSI interrupts in the affinity setter
functional again.
It was broken by a MSI core code update, which restructured the code in
a way that the quirk flag was not longer set correctly.
Trying to restore the core logic caused a deeper inspection and it
turned out that the extra quirk flag is not required at all because
it's the inverse of the reservation mode bit, which only can be set
when the MSI interrupt is maskable.
So the trivial fix is to use the reservation mode check in the affinity
setter function and remove almost 40 lines of code related to the
no-mask quirk flag.
- Cure a Kconfig dependency issue which causes compile fails by correcting
the conditionals in the affected heaer files.
- Clean up coding style in the UV APIC driver.

Update for time, timekeeping and timers:
Core:
- Avoid superfluous deactivation of the tick in the low resolution tick
NOHZ interrupt handler as the deactivation is handled already in the
idle loop and on interrupt exit.
- Update stale comments in the tick NOHZ code and rename the tick
handler functions to be self-explanatory.
- Remove an unused function in the tick NOHZ code, which was forgotten
when the last user went away.
- Handle RTC alarms which exceed the maximum alarm time of the
underlying RTC hardware gracefully.
Setting RTC alarms which exceed the maximum alarm time of the RTC
hardware failed so far and caused suspend operations to abort.
Cure this by limiting the alarm to the maximum alarm time of the RTC
hardware, which is provided by the driver. This causes early resume
wakeups, but that's way better than not suspending at all.
Drivers:
- Add a proper clocksource/event driver for the ancient Cirrus Logic
EP93xx SoC family, which is one of the last non device-tree holdouts
in arch/arm.
- The usual boring device tree bindings updates and small fixes and
enhancements all over the place.

Updates for SMP and CPU hotplug:
- Switch the smp_call_function*() @csd argument to call_single_data_t
type, which is a cache-line aligned typedef of the underlying struct
__call_single_data.
This ensures that the call data is not crossing a cacheline which
avoids bouncing an extra cache-line for the SMP function call
- Prevent offlining of the last housekeeping CPU when CPU isolation is
active.
Offlining the last housekeeping CPU makes no sense in general, but also
caused the scheduler to panic due to the empty CPU mask when rebuilding
the scheduler domains.
- Remove an unused CPU hotplug state

Updates for the interrupt subsytem:
Core:
- Exclude managed interrupts in the calculation of interrupts which are
targeted to a CPU which is about to be offlined to ensure that there
are enough free vectors on the still online CPUs to migrate them over.
Managed interrupts do not need to be accounted because they are
either shut down on offline or migrated to an already reserved and
guaranteed slot on a still online CPU in the interrupts affinity
mask.
Including managed interrupts is overaccounting and can result in
needlessly aborting hibernation on large server machines.
- The usual set of small improvements
Drivers:
- Make the generic interrupt chip implementation handle interrupt
domains correctly and initialize the name pointers correctly
- Add interrupt affinity setting support to the Renesas RZG2L chip
driver.
- Prevent registering syscore operations multiple times in the SiFive
PLIC chip driver.
- Update device tree handling in the NXP Layerscape MSI chip driver

Two small updates to ptrace_stop():
- Add a comment to explain that the preempt_disable() before unlocking
tasklist lock is not a correctness problem and just avoids the tracer
to preempt the tracee before the tracee schedules out.
- Make that preempt_disable() conditional on PREEMPT_RT=n.
RT enabled kernels cannot disable preemption at this point because
cgroup_enter_frozen() and sched_submit_work() acquire spinlocks or
rwlocks which are substituted by sleeping locks on RT. Acquiring a
sleeping lock in a preemption disable region is obviously not possible.
This obviously brings back the potential slowdown of ptrace() for RT
enabled kernels, but that's a price to be payed for latency guarantees.

Locking changes in this cycle are:
- Futex improvements:
- Add the 'futex2' syscall ABI, which is an attempt to get away from the
multiplex syscall and adds a little room for extentions, while lifting
some limitations.
- Fix futex PI recursive rt_mutex waiter state bug
- Fix inter-process shared futexes on no-MMU systems
- Use folios instead of pages
- Micro-optimizations of locking primitives:
- Improve arch_spin_value_unlocked() on asm-generic ticket spinlock
architectures, to improve lockref code generation.
- Improve the x86-32 lockref_get_not_zero() main loop by adding
build-time CMPXCHG8B support detection for the relevant lockref code,
and by better interfacing the CMPXCHG8B assembly code with the compiler.
- Introduce arch_sync_try_cmpxchg() on x86 to improve sync_try_cmpxchg()
code generation. Convert some sync_cmpxchg() users to sync_try_cmpxchg().
- Micro-optimize rcuref_put_slowpath()
- Locking debuggability improvements:
- Improve CONFIG_DEBUG_RT_MUTEXES=y to have a fast-path as well
- Enforce atomicity of sched_submit_work(), which is de-facto atomic but
was un-enforced previously.
- Extend <linux/cleanup.h>'s no_free_ptr() with __must_check semantics
- Fix ww_mutex self-tests
- Clean up const-propagation in <linux/seqlock.h> and simplify
the API-instantiation macros a bit.
- RT locking improvements:
- Provide the rt_mutex_*_schedule() primitives/helpers and use them
in the rtmutex code to avoid recursion vs. rtlock on the PI state.
- Add nested blocking lockdep asserts to rt_mutex_lock(), rtlock_lock()
and rwbase_read_lock().
- Plus misc fixes & cleanups

dt-bindings: soc: fsl: cpm_qe: cpm1-scc-qmc: Add support for QMC HDLC
The QMC (QUICC mutichannel controller) is a controller present in some PowerQUICC SoC such as MPC885. The QMC HDLC uses the QMC controller to transfer HDLC data. Additionally, a framer can be connected to the QMC HDLC. If present, this framer is the interface between the TDM bus used by the QMC HDLC and the E1/T1 line. The QMC HDLC can use this framer to get information about the E1/T1 line and configure the E1/T1 line.

Initial bcachefs pull request for 6.7-rc1
Here's the bcachefs filesystem pull request. One new patch since last week: the exportfs constants ended up conflicting with other filesystems that are also getting added to the global enum, so switched to new constants picked by Amir. I'll also be sending another pull request later on in the cycle bringing things up to date my master branch that people are currently running; that will be restricted to fs/bcachefs/, naturally. Testing - fstests as well as the bcachefs specific tests in ktest: https://evilpiepirate.org/~testdashboard/ci?branch=bcachefs-for-upstream It's also been soaking in linux-next, which resulted in a whole bunch of smatch complaints and fixes and a patch or two from Kees. The only new non fs/bcachefs/ patch is the objtool patch that adds bcachefs functions to the list of noreturns. The patch that exports osq_lock() has been dropped for now, per Ingo.

dt-bindings: arm,coresight-cti: Add missing additionalProperties on child nodes
Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas.

Pull btrfs updates from David Sterba:
"New features:
- raid-stripe-tree
New tree for logical file extent mapping where the physical mapping
may not match on multiple devices. This is now used in zoned mode
to implement RAID0/RAID1* profiles, but can be used in non-zoned
mode as well. The support for RAID56 is in development and will
eventually fix the problems with the current implementation. This
is a backward incompatible feature and has to be enabled at mkfs
time.
- simple quota accounting (squota)
A simplified mode of qgroup that accounts all space on the initial
extent owners (a subvolume), the snapshots are then cheap to create
and delete. The deletion of snapshots in fully accounting qgroups
is a known CPU/IO performance bottleneck.
The squota is not suitable for the general use case but works well
for containers where the original subvolume exists for the whole
time. This is a backward incompatible feature as it needs extending
some structures, but can be enabled on an existing filesystem.
- temporary filesystem fsid (temp_fsid)
The fsid identifies a filesystem and is hard coded in the
structures, which disallows mounting the same fsid found on
different devices.
For a single device filesystem this is not strictly necessary, a
new temporary fsid can be generated on mount e.g. after a device is
cloned. This will be used by Steam Deck for root partition A/B
testing, or can be used for VM root images.
Other user visible changes:
- filesystems with partially finished metadata_uuid conversion cannot
be mounted anymore and the uuid fixup has to be done by btrfs-progs
(btrfstune).
Performance improvements:
- reduce reservations for checksum deletions (with enabled free space
tree by factor of 4), on a sample workload on file with many
extents the deletion time decreased by 12%
- make extent state merges more efficient during insertions, reduce
rb-tree iterations (run time of critical functions reduced by 5%)
Core changes:
- the integrity check functionality has been removed, this was a
debugging feature and removal does not affect other integrity
checks like checksums or tree-checker
- space reservation changes:
- more efficient delayed ref reservations, this avoids building up
too much work or overusing or exhausting the global block
reserve in some situations
- move delayed refs reservation to the transaction start time,
this prevents some ENOSPC corner cases related to exhaustion of
global reserve
- improvements in reducing excessive reservations for block group
items
- adjust overcommit logic in near full situations, account for one
more chunk to eventually allocate metadata chunk, this is mostly
relevant for small filesystems (<10GiB)
- single device filesystems are scanned but not registered (except
seed devices), this allows temp_fsid to work
- qgroup iterations do not need GFP_ATOMIC allocations anymore
- cleanups, refactoring, reduced data structure size, function
parameter simplifications, error handling fixes"

NFSD 6.7 Release Notes
This release completes the SunRPC thread scheduler work that was begun in v6.6. The scheduler can now find an svc thread to wake in constant time and without a list walk. Thanks again to Neil Brown for this overhaul. Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD control plane. The long-term plan is to provide the same functionality as found in /proc/fs/nfsd, plus some interesting additions, and then migrate the NFSD user space utilities to netlink. A long series to overhaul NFSD's NFSv4 operation encoding was applied in this release. The goals are to bring this family of encoding functions in line with the matching NFSv4 decoding functions and with the NFSv2 and NFSv3 XDR functions, preparing the way for better memory safety and maintainability. A further improvement to NFSD's write delegation support was contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the server to retrieve cached size and mtime data from clients holding write delegations. If the server can retrieve this information, it does not have to recall the delegation in some cases. The usual panoply of bug fixes and minor improvements round out this release. As always I am grateful to all contributors, reviewers, and testers. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmU5IuoACgkQM2qzM29m f5eVsg//bVp8S93ci/oDlKfzOwH2fO5e5rna91wrDpJxkd51h6KTx55dSRG5sjAZ EywIVOann6xCtsixAPyff5Cweg2dWvzQRsy1ZnvWQ1qZBzD5KAJY5LPkeSFUCKBo Zani/qTOYbxzgFMjZx+yDSXDPKG68WYZBQK59SI7mURu4SYdk8aRyNY8mjHfr0Vh Aqrcny4oVtXV4sL5P5G/2FUW7WKT3olA3jSYlRRNMhbs2qpEemRCCrspOEMMad+b t1+ZCg+U27PMranvOJnof4RU7peZbaxDWA0gyiUbivVXVtZn9uOs0ffhktkvechL ePc33dqdp2ITdKIPA6JlaRv5WflKXQw0YYM9Kv5mcR4A2el7owL4f/pMlPhtbYwJ IOJv15KdKVN979G2e6WMYiKK+iHfaUUguhMEXnfnGoAajHOZNQiUEo3iFQAD7LDc DvMF8d9QqYmB9IW8FOYaRRfZGJOQHf3TL79Nd08z/bn5swvlvfj77leux9Sb+0/m Luk2Xvz2AJVSXE31wzabaGHkizN+BtH+e4MMbXUHBPW5jE9v7XOnEUFr4UdZyr9P Gl87A7NcrzNjJWT5TrnzM4sOslNsx46Aeg+VuNt2fSRn2dm6iBu2B8s0N4imx6dV PX1y9VSLq5WRhjrFZ1qeiZdsuTaQtrEiNDoRIQR6nCJPAV80iFk= =B4wJ -----END PGP SIGNATURE----- Merge tag 'nfsd-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "This release completes the SunRPC thread scheduler work that was begun in v6.6.

- Convert iter->user_backed to user_backed_iter() in the sound PCM

- Renumber the type enum so that the ITER_* constants match the order

- Since the preceding patch puts UBUF and IOVEC at 0 and 1, change
user_backed_iter() to just use the type value and get rid of the

get optimised away
- Move the check for ->copy_mc to _copy_from_iter() and
copy_page_from_iter_atomic() rather than in memcpy_from_iter_mc()
where it gets repeated for every segment. Instead, we check once
and invoke a side function that can use iterate_bvec() rather than
iterate_and_advance() and supply a different step function

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Rename and export helpers that get write access to a mount. They
are used in overlayfs to get write access to the upper mount.
- Print the pretty name of the root device on boot failure. This
helps in scenarios where we would usually only print
"unknown-block(1,2)".
- Add an internal SB_I_NOUMASK flag. This is another part in the
endless POSIX ACL saga in a way.
When POSIX ACLs are enabled via SB_POSIXACL the vfs cannot strip
the umask because if the relevant inode has POSIX ACLs set it might
take the umask from there. But if the inode doesn't have any POSIX
ACLs set then we apply the umask in the filesytem itself. So we end
up with:
(1) no SB_POSIXACL -> strip umask in vfs
(2) SB_POSIXACL -> strip umask in filesystem
The umask semantics associated with SB_POSIXACL allowed filesystems
that don't even support POSIX ACLs at all to raise SB_POSIXACL
purely to avoid umask stripping. That specifically means NFS v4 and
Overlayfs. NFS v4 does it because it delegates this to the server
and Overlayfs because it needs to delegate umask stripping to the
upper filesystem, i.e., the filesystem used as the writable layer.
This went so far that SB_POSIXACL is raised eve on kernels that
don't even have POSIX ACL support at all.
Stop this blatant abuse and add SB_I_NOUMASK which is an internal
superblock flag that filesystems can raise to opt out of umask
handling. That should really only be the two mentioned above. It's
not that we want any filesystems to do this. Ideally we have all
umask handling always in the vfs.
- Make overlayfs use SB_I_NOUMASK too.
- Now that we have SB_I_NOUMASK, stop checking for SB_POSIXACL in
IS_POSIXACL() if the kernel doesn't have support for it. This is a
very old patch but it's only possible to do this now with the wider
cleanup that was done.
- Follow-up work on fake path handling from last cycle. Citing mostly
from Amir:
When overlayfs was first merged, overlayfs files of regular files
and directories, the ones that are installed in file table, had a
"fake" path, namely, f_path is the overlayfs path and f_inode is
the "real" inode on the underlying filesystem.
In v6.5, we took another small step by introducing of the
backing_file container and the file_real_path() helper. This change
allowed vfs and filesystem code to get the "real" path of an
overlayfs backing file. With this change, we were able to make
fsnotify work correctly and report events on the "real" filesystem
objects that were accessed via overlayfs.
This method works fine, but it still leaves the vfs vulnerable to
new code that is not aware of files with fake path. A recent
example is commit

The same struct bdev_handle is then also passed to block device closing functions. This allows us to propagate context from opening to closing a block device without having to modify all users everytime. Sidenote, in the future we might even want to try and have block device opening functions return a struct file directly but that's a series on top of this. These are further preparatory changes to be able to count writable opens and blocking writes to mounted block devices. That's a separate piece of work for next cycle and for that we absolutely need the changes to btrfs that have been quietly dropped somehow. Originally the series contained a patch that removed the old blkdev_*() helpers. But since this would've caused needles churn in -next for bcachefs we ended up delaying it. The second piece of work addresses one of the major annoyances about the work last cycle, namely that we required dropping s_umount whenever we used the superblock and fs_holder_ops for a block device. The reason for that requirement had been that in some codepaths s_umount could've been taken under disk->open_mutex (that's always been the case, at least theoretically). For example, on surprise block device removal or media change. And opening and closing block devices required grabbing disk->open_mutex as well. So we did the work and went through the block layer and fixed all those places so that s_umount is never taken under disk->open_mutex. This means no more brittle games where we yield and reacquire s_umount during block device opening and closing and no more requirements where block devices need to be closed. Filesystems don't need to care about this. There's a bunch of other follow-up work such as moving block device freezing and thawing to holder operations which makes it work for all block devices and not just the main block device just as we did for surprise removal. But that is for next cycle. Tested with fstests for all major fses, blktests, LTP" * tag 'vfs-6.7.super' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: (37 commits) porting: update locking requirements fs: assert that open_mutex isn't held over holder ops block: assert that we're not holding open_mutex over blk_report_disk_dead block: move bdev_mark_dead out of disk_check_media_change block: WARN_ON_ONCE() when we remove active partitions block: simplify bdev_del_partition() fs: Avoid grabbing sb->s_umount under bdev->bd_holder_lock jfs: fix log->bdev_handle null ptr deref in lbmStartIO bcache: Fixup error handling in register_cache() xfs: Convert to bdev_open_by_path() reiserfs: Convert to bdev_open_by_dev/path() ocfs2: Convert to use bdev_open_by_dev() nfs/blocklayout: Convert to use bdev_open_by_dev/path() jfs: Convert to bdev_open_by_dev() f2fs: Convert to bdev_open_by_dev/path() ext4: Convert to bdev_open_by_dev() erofs: Convert to use bdev_open_by_path() btrfs: Convert to bdev_open_by_path() fs: Convert to bdev_open_by_dev() mm/swap: Convert to use bdev_open_by_dev() ... |

fbdev: stifb: Make the STI next font pointer a 32-bit signed offset
The pointer to the next STI font is actually a signed 32-bit offset. With this change the 64-bit kernel will correctly subract the (signed 32-bit) offset instead of adding a (unsigned 32-bit) offset. It has no effect on 32-bit kernels. This fixes the stifb driver with a 64-bit kernel on qemu. Signed-off-by: Helge Deller <deller@gmx.de> Cc: stable@vger.kernel.org |
