replaces the entire mapping instead of just the part that had been
marked bad in the bitmap, but advances the bitmap cursor in
xrep_cow_replace by the amount replaced. As a result, we fail to
replace the end of the bad range, and replace part of the good range.
Fix this by rewriting the replace method to handle replacing the middle
of a cow fork mapping. This we do by returning both the current mapping
as @got, and the subset of the mapping that we want to replace as @rep,
using @rep to store the results of the new allocation, and comparing
@rep to @got to figure out the exact transformations needed.

xfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode,
a data fork mapping, and a cow fork mapping. Unfortunately, these two
helpers cycle the ILOCK to grab a transaction, which means that the
mappings are stale as soon as we reacquire the ILOCK. Currently we
refresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but
we don't refresh the data fork mapping beforehand, which means that the
xfs_bmap_trim_cow in that function queries the refcount btree about the
wrong physical blocks and returns an inaccurate value in *shared.
If *shared is now false, the directio write proceeds with a stale data
fork mapping. Fix this by querying the data fork mapping if the
sequence counter changes across the ILOCK cycle.

The zoned sysfs directory is currently registered as part of the generic
per-mount sysfs setup, but the data exposed by nr_open_zones has a
narrower lifetime. mp->m_zone_info is allocated by xfs_mount_zones() and
freed by xfs_unmount_zones(), while the zoned sysfs kobject remained
registered until xfs_mount_sysfs_del().
A read of nr_open_zones can therefore enter through the still-live sysfs
kobject after xfs_unmount_zones() has freed mp->m_zone_info, leading to a
use-after-free in nr_open_zones_show().
Make the zoned sysfs lifetime match the zone-info lifetime inside the zone
allocator. Create the zoned sysfs directory from xfs_mount_zones() after
the zone allocator has finished setting up, and remove it as the first
step of xfs_unmount_zones(), before any zone allocator teardown can free
m_zone_info.
Sysfs removal deactivates the kernfs nodes and waits for active callbacks
to drain before returning, so this also protects a reader that has already
entered nr_open_zones_show() but has not yet dereferenced m_zone_info.

If the first op of a transaction is a bare transaction header
(len == sizeof(struct xfs_trans_header)), xlog_recover_add_to_trans()
adds an item but no region, leaving it on r_itemq with ri_cnt == 0 and
ri_buf == NULL.
The header can be split across op records, so later ops may still add
regions; the item is only invalid if the transaction commits with none.
The runtime commit path never emits such a transaction, so this only
happens on a crafted log. It came from an AI-assisted code audit of the
recovery parser.
xlog_recover_reorder_trans() calls ITEM_TYPE() on the item, which reads
*(unsigned short *)item->ri_buf[0].iov_base and faults on the NULL
ri_buf. Reject it there, before the commit handlers that also read
ri_buf[0].

If xfs_metadir_create() fails in xfs_dqinode_metadir_create(), the current
code returns directly, leaking the allocated update and transaction state.
If the subsequent commit fails, the caller-owned inode reference is left
behind.
Fix this memory leak by routing the create failure path through
xfs_metadir_cancel(). For both create and commit failures, finish and
release any inode returned to the caller, mirroring the unwind pattern in
xfs_metadir_mkdir().
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. Runtime validation
used kprobe fault injection during `mount -o uquota` on a metadir XFS
image. Injecting xfs_metadir_create() reproduced the old active-update path
that left mount stuck later in mount setup; after this change, the same
injection reported cancel_hits=1 and irele_hits=1. Injecting
xfs_metadir_commit() exercised the old inode-reference leak path; after
this change, it reported irele_hits=1.

Commit 44f9200699 ("Input: gscps2 - use guard notation when
acquiring spinlock") moved the receive loop into gscps2_read_data()
and gscps2_report_data().
While moving the code, it preserved the writes to
buffer[ps2port->append], but omitted the following producer index
update from the original loop:
ps2port->append = (ps2port->append + 1) & BUFFER_SIZE;
As a result, append never advances. Since gscps2_report_data() only
reports bytes while act != append, the receive buffer always appears
empty and no keyboard or mouse data reaches the serio core.
Restore the omitted index update.

Some touchpads (e.g. ThinkPad T14 Gen 1) have buggy firmware that reports
a register descriptor structure size that is too small for the number of
registers it claims to have in the presence map. The remaining bytes in
the structure are 0, which with the new strict bounds checking causes the
parser to fail with -EIO, aborting the device probe.
Tolerate such short reads by dropping the remaining (unparseable or
0-size) registers from the list instead of failing the probe,
preventing the driver from trying to use them.

The register descriptor presence register is a packet register, which
means its bytes share a single RMI address. It does not occupy
consecutive addresses, and the register structure that follows it
is located at the next RMI address (presence_address + 1), not
(presence_address + presence_size).
Revert the incorrect address calculation introduced in commit
a98518e724.
