atm: remove the unused send_oam / push_oam callbacks
The atmdev_ops::send_oam device operation and the atm_vcc::push_oam callback were the kernel's interface for raw F4/F5 OAM cell exchange. Nothing assigns them a non-NULL value and nothing ever invokes them: the core only ever initialises push_oam to NULL (in vcc_create() and the AAL init helpers) and the Solos driver only lists send_oam = NULL for documentation. The drivers that actually drove OAM through these hooks were removed along with the legacy ATM adapters. Drop both callbacks and the NULL initialisers.

atm: remove AAL3/4 transport support
AAL3/4 is an obsolete connection-oriented ATM adaptation layer that has seen no real use since the SMDS-era hardware it was designed for (90s?). We are only maintaining ATM support in-tree to keep PPPoATM running, and PPPoATM runs over AAL5. Drop the "raw" AAL3/4 transport (atm_init_aal34()) and the ATM_AAL34 cases in the connect and traffic-parameter paths. A vcc_connect() with qos.aal == ATM_AAL34 now fails with -EPROTOTYPE. uAPI cleanup is performed later, separately.

io_uring, audit: don't log IORING_OP_RECV_ZC
IORING_OP_RECV_ZC is a read operation. Audit only tracks file/socket
creation, not subsequent reads. Set audit_skip to align with
audit-userspace uringop_table.h.

io_uring: get rid of tw_pending for !DEFER task work
The normal task_work path used a tw_pending bit to ensure the callback was only added once: the mpscq drains incrementally, so a single tctx_task_work() run can take the queue through empty -> non-empty several times, and each transition would otherwise re-add the already pending callback_head. This corrupts the task_work list, and is what tw_pending protects again. This can go away, if we stop running the task_work as soon as the queue empties.

Merge branch 'idle-time-acc' into features
Heiko Carstens says: =================== This is supposed to improve s390 idle time accounting, and brings it back to the state it was before arch_cpu_idle_time() was removed from s390 [3]. In result all cpu time accounting is done by the s390 architecture backend again, instead of having a mix of architecure specific and common code accounting (common code: idle, s390 architecture: everything else). =================== Signed-off-by: Alexander Gordeev <agordeev@linux.ibm.com> |

regcache: Do not overwrite error code when finalizing cache after error
During regcache initialization, if an error occurs in the
cache_ops->populate callback, and if cache operations include an exit
callback, the error code from populate() is overwritten with the return
value from exit(). This hides the error condition from the caller of
regcache_init(), and can cause NULL pointer dereferences when the regcache
is later accessed.

io_uring/rw: preserve partial result for iopoll
A partial read will store the completed byte count in io->bytes_done.
The regular completion path applies io_fixup_rw_res() so that, when the
following operation reaches EOF, the number of bytes already read is
returned.
The iopoll completion path does not apply this fixup to the return value
and can return zero instead.
Use the fixup result when updating the CQE, and the raw result for the
reissue check.

io_uring/nop: fix file reference leak with IOSQE_FIXED_FILE
NOP file-acquisition support choses between a fixed (registered) file and
a normal fget()'d file based on its own IORING_NOP_FIXED_FILE flag in
sqe->nop_flags. However, a request's REQ_F_FIXED_FILE is set
independently from the generic IOSQE_FIXED_FILE sqe flag during request
init, before the issue handler runs.
If a NOP is submitted with IOSQE_FIXED_FILE set (so REQ_F_FIXED_FILE is
set) but without IORING_NOP_FIXED_FILE, io_nop() takes the normal path
and grabs a real reference via io_file_get_normal(). On completion,
io_put_file() only drops the reference when REQ_F_FIXED_FILE is clear,
so the fget()'d file is never released and leaks:
BUG: memory leak
unreferenced object 0xffff88800f42c240 (size 176):
kmem_cache_alloc_noprof+0x358/0x440
alloc_empty_file+0x57/0x180
path_openat+0x44/0x1e50
do_file_open+0x121/0x200
do_sys_openat2+0xa7/0x150
__x64_sys_openat+0x82/0xf0
Decide between fixed and normal file acquisition from REQ_F_FIXED_FILE,
the same way io_assign_file() does for every other opcode, and fold
IORING_NOP_FIXED_FILE into REQ_F_FIXED_FILE at prep time.

powerpc/fadump: define MIN_RMA in bytes rather than MB
The MIN_RMA size checks in fadump_setup_param_area() use (MIN_RMA * 1024 * 1024), which is evaluated in int and can overflow when MIN_RMA is increased to values such as SZ_2G, triggering compiler warnings such as: warning: integer overflow in expression of type 'int' results in '0' [-Woverflow] Define MIN_RMA directly in bytes using SZ_1M and update the callers accordingly. This avoids repeated unit conversions and prevents integer overflow. Also convert MIN_RMA back to MB when populating the firmware architecture vector, since firmware expects the value in MB.

powerpc: Restore KUAP registers on syscall restart exit
During a syscall restart, block KUAP so that pending interrupts can be
replayed. The original KUAP state is not restored before returning to
userspace, causing subsequent userspace accesses to fault and eventually
trigger bad_access_pkey(), crashing the kernel.
The original KUAP register values are already saved in
arch_enter_from_user_mode(). Restore them on the syscall restart exit
path before returning to userspace.

gpio: mlxbf3: fail probe if gpiochip registration fails
mlxbf3_gpio_probe() logs a devm_gpiochip_add_data() failure but still
returns success. That leaves the platform device bound even though the
GPIO chip was not registered.
Return the registration error so probe failure matches the missing
gpiochip state.

Both the local (DEFER_TASKRUN) and the normal (tctx) task_work lists were llist based, which is LIFO ordered, and hence each run had to do an O(n) list reversal pass first to restore queue order. Additionally, to cap the amount of task_work run, each method needed a retry list as well. Add a lockless MPCS FIFO queue (based on Dmitry Vyukov's intrusive MPSC algorithm) and switch both task_work lists to it. It performs better than llists and we can then also ditch the retry lists as well as entries are popped one-at-the-time. On top of those changes, run the tctx fallback task_work directly and remove the now-unused per-ctx fallback machinery entirely. - zcrx user notifications. Add a mechanism for zcrx to communicate conditions back to userspace via a dedicated CQE, with the initial users being notification on running out of buffers and on a frag copy fallback, plus shared-memory notification statistics. Alongside that, a series of zcrx reliability and cleanup fixes: more reliable scrubbing, poisoning pointers on unregistration, dropping an extra ifq close, adding a ctx back-pointer, reordering fd allocation in the export path, and killing a dead 'sock' member. - Allow using io_uring registered buffers for plain SEND and RECV, not just for the zero-copy send path. This enables targets like ublk's NBD backend to push/pull IO data directly to/from a registered buffer over a plain send/recv on a TCP socket. - Registered buffer improvements: account huge pages correctly, bump the io_mapped_ubuf length field to size_t, and raise the previous 1GB registered buffer size limit. - Restrict the ctx access exposed to io_uring BPF struct_ops programs by handing them an opaque type rather than the full io_ring_ctx, and add a separate MAINTAINERS entry for the bpf-ops code. - Allow opcode filtering on IORING_OP_CONNECT. - Validate ring-provided buffer addresses with access_ok(), and align the legacy buffer add limit with MAX_BIDS_PER_BGID. - Various other cleanups and minor fixes, including avoiding msghdr async data on connect/bind, dropping async_size for OP_LISTEN, making the POLL_FIRST receive side checks consistent, re-checking IO_WQ_BIT_EXIT for each linked work item, and using trace_call__##name() at guarded tracepoint call sites. * tag 'for-7.2/io_uring-20260615' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (31 commits) io_uring/bpf-ops: add a separate maintainer entry io_uring/net: make POLL_FIRST receive side checks consistent io_uring: remove the per-ctx fallback task_work machinery io_uring: run the tctx task_work fallback directly io_uring: switch normal task_work to a mpscq io_uring: switch local task_work to a mpscq io_uring/mpscq: add lockless multi-producer, single-consumer FIFO queue io_uring: grab RCU read lock marking task run io_uring/zcrx: kill dead 'sock' member in struct io_zcrx_args io_uring/kbuf: validate ring provided buffer addresses with access_ok() io_uring/net: support registered buffer for plain send and recv io_uring/nop: Drop a wrong comment in struct io_nop io_uring/net: Remove async_size for OP_LISTEN io_uring/net: Avoid msghdr on op_connect/op_bind async data io_uring/bpf-ops: restrict ctx access to BPF io_uring/io-wq: re-check IO_WQ_BIT_EXIT for each linked work item io_uring/kbuf: align legacy buffer add limit with MAX_BIDS_PER_BGID io_uring/zcrx: add shared-memory notification statistics io_uring/zcrx: notify user on frag copy fallback io_uring/zcrx: notify user when out of buffers ... |

Pull hfs/hfsplus updates from Viacheslav Dubeyko:
"Several fixes in HFS/HFS+ of syzbot reported issues and HFS//HFS+
fixes of xfstests failures.
- fix a null-ptr-deref issue reported by syzbot (Edward Adam Davis)
If the attributes file is not loaded during system mount
hfsplus_create_attributes_file can dereference a NULL pointer.
Also, add a b-tree node size check in hfs_btree_open() with the
goal to prevent an uninit-value bug reported by syzbot for the case
of corrupted HFS+ image.
- fix __hfs_bnode_create() by using kzalloc_flex() instead of
kzalloc() (Rosen Penev)
- fix early return in hfs_bnode_read() (Tristan Madani)
hfs_bnode_read() can return early without writing to the output

Pull nilfs2 updates from Viacheslav Dubeyko:
"Fixes of syzbot reported issue and various small fixes in NILFS2
functionality.
- fix hung task in nilfs_transaction_begin() (Deepanshu Kartikey)
Reported by syzbot. The root cause is that user-supplied segment
numbers were not validated before nilfs_clean_segments() began
doing work; the range check on each segnum was performed deep
inside the call chain by nilfs_sufile_updatev(), which emits a
nilfs_warn() per invalid entry while still holding the segctor lock
and the sufile mi_sem.
Fix it by validating the contents of kbufs[4] in
nilfs_clean_segments() immediately after acquiring ns_segctor_sem
via nilfs_transaction_lock().
- fix a smatch warning in nilfs_mkdir() warn (Hongling Zeng)
This corrects a semantic issue related to the use of the
ERR_PTR macro that arose from a recent VFS change.
- fix a backing_dev_info reference leak (Shuangpeng Bai)
setup_bdev_super() initializes sb->s_bdev and takes a reference on
the block device backing_dev_info when assigning sb->s_bdi.
nilfs_fill_super() takes another reference to the same
backing_dev_info and stores it in sb->s_bdi again. The extra
reference is not paired with a matching bdi_put(), since
generic_shutdown_super() releases sb->s_bdi only once.
Drop the redundant bdi_get() in nilfs_fill_super(). The single
reference taken by setup_bdev_super() is enough and is released
during superblock shutdown"

Pull btrfs updates from David Sterba:
"The most noticeable change is to enable large folios by default, it's
been in testing for a few releases. Related to that is huge folio
support (still under experimental config). Otherwise a few ioctl
updates, performance improvements and usual fixes and core changes.
User visible changes:
- enable large folios by default, added in 6.17 (under experimental
build), no feature limitations, a big change internally
- new ioctl to return raw checksums to userspace (a bit tricky given
compression and tail extents), can be used for mkfs and
deduplication optimizations
- provide stable UUID for e.g. overlayfs and temp_fsid, also
reflected in statvfs() field f_fsid, internal dev_t is hashed in to
allow cloning
- add 32bit compat version of GET_SUBVOL_INFO ioctl
- in experimental build, support huge folios (up to 2M)
Performance related improvements/changes:
- limit bio size to the estimated optimum derived from the queue,
this prevents build up of too much data for writeback, which could
cause latency spikes (reported improvement 15% on sequential
writes)
- don't force direct IO to be serialized, forgotten change during
mount API port, brings back +60% of throughput
- lockless calculation of number of shrinkable extent maps, improve
performance with many memcg allocated objects
Notable fixes:
- in zoned mode, fix a deadlock due to zone reclaim and relocation
when space needs to be flushed
- don't trim device which is internally not tracked as writeable
(e.g. when missing device is being rescanned)
- fix deadlock when cloning inline extent and mounted with
flushoncommit
- fix false IO failures after direct IO falls back to buffered write
in some cases
Core:
- remove COW fixup mechanism completely; detect and fix changes to
pages outside of filesystem tracking, guaranteed since 5.8, grace
period is over
- remove 2K block size support, experimental to test subpage code on
x86_64 but now it would block folio changes
- tree-checker improvements of:
- free-space cache and tree items
- root reference and backref items
- extent state exceptions in reloc tree
- subpage mode updates:
- code optimizations, simplify tracking bitmaps
- re-enable readahead of compressed extent
- extend bitmap size to cover huge folios
- add tracepoints related to sync, tree-log and transactions
- device stats item tracking unification, remove item if there are no
stats recorded, also don't leave stale stats on replaced device
- allow extent buffer pages to be allocated as movable, to help page
migration
- added checks for proper extent buffer release
- btrfs.ko code size reduction due to transaction abort call
simplifications
- several struct size reductions
- more auto free conversions
- more verbose assertions"

Input: mms114 - reject an oversized device packet size
mms114_interrupt() reads a packet of touch data from the device into a
fixed-size on-stack buffer
struct mms114_touch touch[MMS114_MAX_TOUCH];
which holds MMS114_MAX_TOUCH (10) events of MMS114_EVENT_SIZE (8) bytes,
i.e. 80 bytes. The length of the I2C read into it is taken verbatim from
the device:
packet_size = mms114_read_reg(data, MMS114_PACKET_SIZE);
if (packet_size <= 0)
goto out;
...
error = __mms114_read_reg(data, MMS114_INFORMATION, packet_size,
(u8 *)touch);
packet_size is a single device register byte (0x0F) and the only check
is the lower bound packet_size <= 0; it is never bounded against the
size of touch[]. A malfunctioning, malicious or counterfeit controller
(or an attacker tampering with the I2C bus) can report a packet_size of
up to 255, so __mms114_read_reg() writes up to 175 bytes past the end of
touch[] on the IRQ-thread stack: a stack out-of-bounds write that can
overwrite the stack canary, saved registers and the return address.
A well-formed device never reports more than the buffer holds, so reject
an oversized packet and drop the report, consistent with the handler's
other error paths, rather than reading past the buffer.
Fixes:

Things have calmed down a bit on the docs front, with no earthshaking
changes this time around:
- Ongoing work on the Japanese and Portuguese translations.
- Better integration of the MAINTAINERS file into the rendered documents,
including a search interface.
- A seemingly infinite supply of fixes for typos, minor grammatical issues,
and related problems that LLMs find with abandon.
