dm_get_plane_scale doesn't take into account plane scaled size equal to
zero, leading to a kernel oops due to division by zero. Fix by setting
out-scale size as zero when the dst size is zero, similar to what is
done by drm_calc_scale(). This issue started with the introduction of
cursor ovelay mode that uses this function to assess cursor mode changes
via dm_crtc_get_cursor_mode() before checking plane state.

DC driver is using two different values to define the maximum number of
surfaces: MAX_SURFACES and MAX_SURFACE_NUM. Consolidate MAX_SURFACES as
the unique definition for surface updates across DC.
It fixes page fault faced by Cosmic users on AMD display versions that
support two overlay planes, since the introduction of cursor overlay
mode.

[WHY & HOW]
commit 7fb363c57522 ("drm/amd/display: Let drm_crtc_vblank_on/off manage interrupts")
lets drm_crtc_vblank_* to manage interrupts in amdgpu_dm_crtc_set_vblank,
and amdgpu_irq_get/put do not need to be called here. Part of that
patch got lost somehow, so fix it up.

Pull vfs fixes from Christian Brauner:
- Relax assertions on failure to encode file handles
The ->encode_fh() method can fail for various reasons. None of them
warrant a WARN_ON().
- Fix overlayfs file handle encoding by allowing encoding an fid from
an inode without an alias
- Make sure fuse_dir_open() handles FOPEN_KEEP_CACHE. If it's not
specified fuse needs to invaludate the directory inode page cache
- Fix qnx6 so it builds with gcc-15
- Various fixes for netfslib and ceph and nfs filesystems:
- Ignore silly rename files from afs and nfs when building header
archives
- Fix read result collection in netfslib with multiple subrequests
- Handle ENOMEM for netfslib buffered reads
- Fix oops in nfs_netfs_init_request()
- Parse the secctx command immediately in cachefiles
- Remove a redundant smp_rmb() in netfslib
- Handle recursion in read retry in netfslib
- Fix clearing of folio_queue
- Fix missing cancellation of copy-to_cache when the cache for a
file is temporarly disabled in netfslib
- Sanity check the hfs root record
- Fix zero padding data issues in concurrent write scenarios
- Fix is_mnt_ns_file() after converting nsfs to path_from_stashed()
- Fix missing declaration of init_files
- Increase I/O priority when writing revoke records in jbd2
- Flush filesystem device before updating tail sequence in jbd2
* tag 'vfs-6.13-rc7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (23 commits)

Since the input data length passed to zlib_compress_folios() can be
arbitrary, always setting strm.avail_in to a multiple of PAGE_SIZE may
cause read-in bytes to exceed the input range. Currently this triggers
an assert in btrfs_compress_folios() on the debug kernel (see below).
Fix strm.avail_in calculation for S390 hardware acceleration path.

Since commit 559218d43ec9 ("block: pre-calculate max_zone_append_sectors"),
queue_limits's max_zone_append_sectors is default to be 0 and it is only
updated when there is a zoned device. So, we have
lim->max_zone_append_sectors = 0 when there is no zoned device in the
filesystem.
That leads to fs_info->max_zone_append_size and thus
fs_info->max_extent_size to be 0, which is wrong and can for example
lead to a divide by zero in count_max_extents().
Fix this by only capping fs_info->max_extent_size to
fs_info->max_zone_append_size when it is non-zero.
Based on a patch from Naohiro Aota <naohiro.aota@wdc.com>, from which
much of this commit message is stolen as well.

</TASK>
[CAUSE]
The reproducer is using a corrupted image where extent tree root is
corrupted, thus forcing to use "rescue=all,ro" mount option to mount the
image.
Then it triggered a scrub, but since scrub relies on extent tree to find
where the data/metadata extents are, scrub_find_fill_first_stripe()
relies on an non-empty extent root.
But unfortunately scrub_find_fill_first_stripe() doesn't really expect
an NULL pointer for extent root, it use extent_root to grab fs_info and
triggered a NULL pointer dereference.
[FIX]
Add an extra check for a valid extent root at the beginning of
scrub_find_fill_first_stripe().
The new error path is introduced by 42437a6386ff ("btrfs: introduce
mount option rescue=ignorebadroots"), but that's pretty old, and later
commit b979547513ff ("btrfs: scrub: introduce helper to find and fill
sector info for a scrub_stripe") changed how we do scrub.
So for kernels older than 6.6, the fix will need manual backport.

Amir Goldstein <amir73il@gmail.com> says:
This is a followup fix to the reported regression [1] that was
introduced by overlayfs non-decodable file handles support in v6.6.
The first fix posted two weeks ago [2] was a quick band aid which is
justified on its own and is still queued on your vfs.fixes branch.
This followup fix fixes the root cause of overlayfs file handle encoding
failure and it also solves a bug with fanotify FAN_DELETE_SELF events on
overlayfs, that was discovered from analysis of the first report.
The fix to fanotify delete events was verified with a new LTP test [3].

Dmitry Safonov reported that a WARN_ON() assertion can be trigered by
userspace when calling inotify_show_fdinfo() for an overlayfs watched
inode, whose dentry aliases were discarded with drop_caches.
The WARN_ON() assertion in inotify_show_fdinfo() was removed, because
it is possible for encoding file handle to fail for other reason, but
the impact of failing to encode an overlayfs file handle goes beyond
this assertion.
As shown in the LTP test case mentioned in the link below, failure to
encode an overlayfs file handle from a non-aliased inode also leads to
failure to report an fid with FAN_DELETE_SELF fanotify events.
As Dmitry notes in his analyzis of the problem, ovl_encode_fh() fails
if it cannot find an alias for the inode, but this failure can be fixed.
ovl_encode_fh() seldom uses the alias and in the case of non-decodable
file handles, as is often the case with fanotify fid info,
ovl_encode_fh() never needs to use the alias to encode a file handle.
Defer finding an alias until it is actually needed so ovl_encode_fh()
will not fail in the common case of FAN_DELETE_SELF fanotify events.

In the smb2_send_interim_resp(), if ksmbd_alloc_work_struct()
fails to allocate a node, it returns a NULL pointer to the
in_work pointer. This can lead to an illegal memory write of
in_work->response_buf when allocate_interim_rsp_buf() attempts
to perform a kzalloc() on it.
To address this issue, incorporating a check for the return
value of ksmbd_alloc_work_struct() ensures that the function
returns immediately upon allocation failure, thereby preventing
the aforementioned illegal memory access.

In commit d1d991efaf34 ("selinux: Add netlink xperm support") a new
extended permission was added ("nlmsg"). This was the second extended
permission implemented in selinux ("ioctl" being the first one).
Extended permissions are associated with a base permission. It was found
that, in the access vector cache (avc), the extended permission did not
keep track of its base permission. This is an issue for a domain that is
using both extended permissions (i.e., a domain calling ioctl() on a
netlink socket). In this case, the extended permissions were
overlapping.
Keep track of the base permission in the cache. A new field "base_perm"
is added to struct extended_perms_decision to make sure that the
extended permission refers to the correct policy permission. A new field
"base_perms" is added to struct extended_perms to quickly decide if
extended permissions apply.
While it is in theory possible to retrieve the base permission from the
access vector, the same base permission may not be mapped to the same
bit for each class (e.g., "nlmsg" is mapped to a different bit for
"netlink_route_socket" and "netlink_audit_socket"). Instead, use a
constant (AVC_EXT_IOCTL or AVC_EXT_NLMSG) provided by the caller.

The existing SW-FW interaction flow on the driver is wrong. Follow this
wrong flow, driver would never return error if there is a unknown command.
Since firmware writes back 'firmware ready' and 'unknown command' in the
mailbox message if there is an unknown command sent by driver. So reading
'firmware ready' does not timeout. Then driver would mistakenly believe
that the interaction has completed successfully.
It tends to happen with the use of custom firmware. Move the check for
'unknown command' out of the poll timeout for 'firmware ready'. And adjust
the debug log so that mailbox messages are always printed when commands
timeout.

After update only the first shot of a multishot timeout request adheres
to the new timeout value while all subsequent retries continue to use
the old value. Don't forget to update the timeout stored in struct
io_timeout_data.

After previous change rshift >= 32 is no longer allowed.
Modify the test to use 31, the test doesn't seem to send
any traffic so the exact value shouldn't matter.

If the backlog of listen() is set to zero, sk_acceptq_is_full() allows
one connection to be made, but inet_csk_reqsk_queue_is_full() does not.
When the net.ipv4.tcp_syncookies is zero, inet_csk_reqsk_queue_is_full()
will cause an immediate drop before the sk_acceptq_is_full() check in
tcp_conn_request(), resulting in no connection can be made.
This patch tries to keep consistent with 64a146513f8f ("[NET]: Revert
incorrect accept queue backlog changes.").

802.2+LLC+SNAP frames received by napi_complete_done() with GRO and DSA
have skb->transport_header set two bytes short, or pointing 2 bytes
before network_header & skb->data. This was an issue as snap_rcv()
expected offset to point to SNAP header (OID:PID), causing packet to
be dropped.
A fix at llc_fixup_skb() (a024e377efed) resets transport_header for any
LLC consumers that may care about it, and stops SNAP packets from being
dropped, but doesn't fix the problem which is that LLC and SNAP should
not use transport_header offset.
Ths patch eliminates the use of transport_header offset for SNAP lookup
of OID:PID so that SNAP does not rely on the offset at all.
The offset is reset after pull for any SNAP packet consumers that may
(but shouldn't) use it.

The struct device_node *next pointer is not initialized, and it is
used in an error path in which it may have never been modified by
function mtk_drm_of_get_ddp_ep_cid().
Since the error path is relying on that pointer being NULL for the
OVL Adaptor and/or invalid component check and since said pointer
is being used in prints for %pOF, in the case that it points to a
bogus address, the print may cause a KP.
To resolve that, initialize the *next pointer to NULL before usage.

Pull io_uring fixes from Jens Axboe:
- Fix an issue with the read multishot support and posting of CQEs from
io-wq context
- Fix a regression introduced in this cycle, where making the timeout
lock a raw one uncovered another locking dependency. As a result,
move the timeout flushing outside of the timeout lock, punting them
to a local list first
- Fix use of an uninitialized variable in io_async_msghdr. Doesn't
really matter functionally, but silences a valid KMSAN complaint that
it's not always initialized
- Fix use of incrementally provided buffers for read on non-pollable
files, where the buffer always gets committed upfront. Unfortunately
the buffer address isn't resolved first, so the read ends up using
the updated rather than the current value
