If device_link_add() fails in snd_soc_bind_card() just skip that
driver pair and carry on.
This means that ASoC must now keep track of which components it was
able to device_link to the card->dev. The new card_device_link member
of struct snd_soc_component is non-NULL if a device_link exists.
The intent of the device link is to ensure that the machine driver
system-suspends before the component drivers, to prevent ASoC
suspend attempting to reconfigure a driver that has already suspended.
It isn't possible to create this device link if the machine driver is
a parent of the component driver or already has a device_link in the
opposite direction. In this case skip the link. A warn is placed in
kernel log since this might indicate a genuine design problem with
those two drivers (this can be downgraded to dbg in future when
people are happy that all these special drivers correctly handle their
reversed shutdown order).

Replace the gem-vram memory manager with gem-shmem. Makes the driver more
robust and enables dma-buf sharing with other hardware.
Gem-vram was created from various drivers that used TTM for their memory
management. All these drivers have meanwhile been converted to gem-shmem.
Using gem-vram is deprecated because it has several problems.
* TTM requires significant overcommitment of video memory for reliable
page flips. There needs to be 3 times the size of the largest possible
framebuffer available or page flips can fail. This leaves the display
dark without further warning. Hibmc hardware with 32 MiB and a maximum
framebuffer size of 1920x2000 is at the limit.
* No dma-buf sharing without GTT support. Neither gem-vram nor hibmc
hardware support a GTT address space. This is required to share buffers
with other devices via dma-buf interfaces.
* TTM requires hardware-accelerated rendering into video memory for
optimal results. As hibmc hardware cannot do this, hibmc renders in
system memory and copies the result to video memory. This can be more
effectively implemented with gem-shmem and DRM's shadow-plane helpers.
Converting hibmc to gem-shmem and shadow-plane helpers.
* Replace gem-vram entry points in struct drm_driver with gem-shmem
equivalents. This makes the driver allocate struct drm_gem_shmem_object
for its buffers.
* Use DRM_GEM_SHADOW_*_PLANE for its plane funcs and plane-helper
funcs. The shadow-plane helpers map a plane's gem buffer objects into
kernel address space during a page flip, so that atomic_update can
copy them to video memory.
* Handle framebuffer damage in hibmc_plane_atomic_update(). This updates
video memory from the plane's framebuffer. It automatically synchronizes
shared buffers with other devices. Create the framebuffer with
drm_gem_fb_create_with_dirty() to trigger the update on each page flip.
* Initialize the plane with drm_plane_enable_fb_damage_clips() to limit
the damage updates to the framebuffer areas that changed. We don't want
to do a full-buffer memcpy if only a small area has changed.
* Test display modes against the available video memory in
hibmc_mode_config_mode_valid(). We only want to announce display modes
that fit into display memory.
* Map the display memory itself into kernel address space.
* Do not set drm_mode_config.prefer_shadow. This would advise user space
to install a shadow buffer. But with gem-shmem, the gem buffer object
already acts as a shadow buffer for video memory.
We use these patterns in many other drivers with similar limitation as
hibmc and its hardware. With these changes in place, hibmc is more robust
and better integrated into the overall DRM framework.

====================
pull request (net): ipsec 2026-06-22
1) xfrm: use compat translator only for u64 alignment mismatch
Gate the XFRM_USER_COMPAT translator on COMPAT_FOR_U64_ALIGNMENT
so 32-bit compat tasks on arches whose 32-bit ABI already matches
the native 64-bit layout are no longer rejected with -EOPNOTSUPP.
From Sanman Pradhan.
2) net: af_key: initialize alg_key_len for IPComp states
Initialize the alg_key_len to 0 in the IPComp branch of
pfkey_msg2xfrm_state() so an uninitialized value cannot drive
xfrm_alg_len() into a slab-out-of-bounds kmemdup during
XFRM_MSG_MIGRATE. From Zijing Yin.
3) xfrm: Fix dev use-after-free in xfrm async resumption
Stash the original skb->dev and extend the RCU critical section
across xfrm_rcv_cb() and transport_finish() to prevent a
tunnel-device UAF and original-device refcount leak when a
callback replaces skb->dev. From Dong Chenchen.
4) xfrm: Fix xfrm state cache insertion race
Move the state-validity check inside xfrm_state_lock in the
input state cache insertion path so a state cannot be killed
between the check and the insert. From Herbert Xu.
5) xfrm: annotate data-races around xfrm_policy_count[] and xfrm_policy_default[]
Add READ_ONCE()/WRITE_ONCE() annotations on xfrm_policy_count
and xfrm_policy_default to silence the KCSAN data race reported
on net->xfrm.policy_count. From Eric Dumazet.
6) espintcp: use sk_msg_free_partial to fix partial send
Replace the manual skmsg accounting in espintcp with
sk_msg_free_partial() so the skmsg stays consistent on every
iteration and the partial-send accounting bugs go away.
From Sabrina Dubroca.
7) xfrm: validate selector family and prefixlen during match
Reject mismatched address families in xfrm_selector_match() and
bound prefixlen in addr4_match()/addr_match() to prevent the
shift-out-of-bounds syzbot reported when an AF_UNSPEC selector
with a large prefixlen is matched against an IPv4 flow.

Currently, pci_create_legacy_files() and pci_remove_legacy_files() are
no-op stubs. With legacy attributes now handled by static groups
registered via pcibus_groups[], no call site needs them.
Remove both functions, their declarations, and the call sites in
pci_register_host_bridge(), pci_alloc_child_bus(), and pci_remove_bus().
Remove the pci_sysfs_init() late_initcall and sysfs_initialized. The
late_initcall originally existed to create all the dynamic PCI sysfs files,
but with both resource and legacy attributes now handled by static groups,
it is no longer needed.
Remove the legacy_io and legacy_mem fields from struct pci_bus which were
used to track the dynamically allocated legacy attributes.

On platforms with HAVE_PCI_MMAP or ARCH_GENERIC_PCI_MMAP_RESOURCE, resource
files are now handled by static attribute groups registered via
pci_dev_groups[].
Stub out the pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files(),
as the dynamic resource file creation is no longer needed.
Also, simplify pci_sysfs_init() on these platforms to only iterate buses
for legacy attributes creation, skipping the per-device loop.
Move the __weak stubs for pci_create_resource_files() and
pci_remove_resource_files() into the #else branch since only platforms
without HAVE_PCI_MMAP (such as Alpha architecture) still need them. Guard
the res_attr[] and res_attr_wc[] fields in struct pci_dev the same way.

Currently, the PCI resource files (resourceN, resourceN_wc) are dynamically
created by pci_create_sysfs_dev_files(), called from both
pci_bus_add_device() and the pci_sysfs_init() late_initcall, with only a
sysfs_initialized flag for synchronisation. This has caused warnings and
boot panics when both paths race on the same device, e.g.:
sysfs: cannot create duplicate filename '/devices/pci0000:3c/0000:3c:01.0/0000:3e:00.2/resource2'
This is especially likely on Devicetree-based platforms, where the PCI host
controllers are platform drivers that probe via the driver model, which can
happen during or after the late_initcall. As such, pci_bus_add_device()
and pci_sysfs_init() are more likely to overlap.
Convert to static const attributes with three attribute groups (I/O, UC,
WC), each with an .is_bin_visible() callback that checks resource flags,
BAR length, and non_mappable_bars. A .bin_size() callback provides
pci_resource_len() to the kernfs node for correct stat and lseek behaviour.
As part of this conversion:
- Rename pci_read_resource_io() and pci_write_resource_io() to
pci_read_resource() and pci_write_resource() since the callbacks are no
longer I/O-specific in the static attribute context.
- Update __resource_resize_store() to use sysfs_create_groups() and
sysfs_remove_groups(), which re-evaluates visibility and runs the
.bin_size() callback for the static resource attribute groups.
- Remove pci_create_resource_files(), pci_remove_resource_files(), and
pci_create_attr() which are no longer needed.
- Move the __weak stubs outside the #if guard so they remain available
for callers converted in subsequent commits.
Platforms that do not define the HAVE_PCI_MMAP macro or the
ARCH_GENERIC_PCI_MMAP_RESOURCE macro, such as Alpha architecture,
continue using their platform-specific resource file creation.
For reference, the dynamic creation dates back to the pre-Git era:
https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/drivers/pci/pci-sysfs.c?id=42298be0eeb5ae98453b3374c36161b05a46c5dc
The write-combine support was added in commit 45aec1ae72fc ("x86: PAT
export resource_wc in pci sysfs").

As SoundWire devices tend to enumerate on the bus after probe, drivers
frequently need to wait for the device to initialise from common driver
code. The common system is to split drivers into a core module and then
a module for each communication bus. These two facts tend to cause
Kconfig issues, the issue tends to be when SOUNDWIRE=m and DRIVER_I2C=y,
this usually selects DRIVER=y. The driver code then wants to call
sdw_slave_wait_for_init(), but this results in calling a module function
from built in code. A depends on SOUNDWIRE | !SOUNDWIRE could be added to
the end driver but this seems slightly off as it adds a lot of counter
intuitive depends.
A simpler solution is to make sdw_slave_wait_for_init() a static inline
function. As part of doing this add a check for the slave device being
NULL acknowledging that this is likely called from code that is shared
between control buses. It does require dropping the call to
sdw_show_ping_status() but this can be added back in end drivers that
used it originally.
Currently this is causing rand config issues on RT5682 and will soon
also cause similar problems on cs42l43.

Store tiling function pointer in struct intel_panic instead of struct
intel_framebuffer, and store struct intel_panic pointer instead of
struct intel_framebuffer pointer in struct drm_scanout_buffer private
member.
To make this happen, pass the tiling function pointer to panic setup
hook, and initialize sb->private in the hook for clarity.
This allows us to drop the dependency on struct intel_framebuffer from
i915 and xe panic code.
Note: It would be less verbose to have a typedef for the tiling function
pointer. However, there isn't a nice location for it that wouldn't also
increase header interdependencies.

Memoryless force-feedback devices use a timer to manage playback of
effects. When a driver for such a device is unbound (or the device is
unregistered for other reasons), the driver typically frees its private
data synchronously. However, the input_dev structure (and its associated
force-feedback structures, including the timer) is only freed when the
last user closes the corresponding device node.
If userspace keeps the device node open while the device is unregistered
(e.g., during driver unbind), the force-feedback timer can still fire
after the driver's private data has been freed.
Introduce a new 'stop' callback to struct ff_device, and call it from
input_unregister_device() before the device is deleted. Implement this
callback for memoryless devices and synchronously shut down the timer to
ensure it is stopped and cannot be rearmed once unregistration happens.

"The most notable change is the removal of the fscache backend: it has
been deprecated for almost two years, mainly because EROFS file-backed

provide better functionality and simpler codebase. In addition,
fscache has depended on netfslib for years, which is undesirable for
EROFS since it is a local filesystem. More details in [1].
In addition, sparse support has been added to the pcluster layout,
which is helpful for large sparse AI datasets, and map requests for
chunk-based inodes have been optimized to be more efficient as well.
There are also the usual fixes and cleanups.

When CONFIG_IP_MULTIPLE_TABLES is enabled but no rule is added,
fib_lookup() performs route lookup directly on two tables.
Since the first lookup does not properly bail out, the result
of an error route in the merged local/main table could be
overwritten by another route in the default table:
# unshare -n
# ip link set lo up
# ip route add 192.168.0.0/24 dev lo table 253
# ip route add unreachable 192.168.0.0/24
# ip route get 192.168.0.1
192.168.0.1 dev lo table default uid 0
cache <local>
Once a random rule is added, the error route is respected:
# ip rule add table 0
# ip rule del table 0
# ip route get 192.168.0.1
RTNETLINK answers: No route to host

Add a new function rtc_read_next_alarm() that reads the next expiring
alarm from the RTC timerqueue. This is different from rtc_read_alarm(),
which only reads the aie_timer.
The wakealarm sysfs file programs the rtc->aie_timer, whereas the
alarmtimer suspend routine programs its own timer into the RTC timerqueue.
Both timers end up in the RTC's timerqueue, and the first expiring timer
is what gets armed in the hardware.
This new function allows code to query which alarm will actually fire
next, regardless of which subsystem programmed it. This is needed by
platform code that needs to program secondary timers based on the
actual next wakeup time.

Add the debugfs and trace plumbing used to trigger and observe
manual client reset.
The reset interface exposes a trigger file for operator-initiated
reset and a status file for tracking the most recent run. The
tracepoints record scheduling, completion, and blocked caller
behavior so reset progress can be diagnosed from the client side.
debugfs layout under /sys/kernel/debug/ceph/<client>/reset/:
trigger - write to initiate a manual reset
status - read to see the most recent reset result
The reset directory is cleaned up via debugfs_remove_recursive()
on the parent, so individual file dentries are not stored.
Tracepoints:
ceph_client_reset_schedule - reset queued
ceph_client_reset_complete - reset finished (success or failure)
ceph_client_reset_blocked - caller blocked waiting for reset
ceph_client_reset_unblocked - caller unblocked after reset
All tracepoints use a null-safe access for monc.auth->global_id
to guard against early-init or late-teardown edge cases.

f2fs_recover_orphan_inodes() trusts the orphan block entry_count when
replaying orphan inodes from the checkpoint pack. A corrupted entry_count
larger than F2FS_ORPHANS_PER_BLOCK makes the recovery loop read past the
ino[] array and interpret footer or following data as inode numbers.
On a crafted image, mounting an unpatched kernel can drive orphan recovery
into f2fs_bug_on() and panic the kernel. Validate entry_count before
consuming entries so corrupted checkpoint data fails the mount with
-EFSCORRUPTED and requests fsck instead.
Set ERROR_INCONSISTENT_ORPHAN as well, so the corruption reason can be
recorded in the superblock s_errors[] field. This gives fsck a persistent
hint even though mount-time orphan recovery failure may leave no chance to
persist SBI_NEED_FSCK through a checkpoint.

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net. This batches
fixes for real crashes with trivial/correctness fixes. There is too
a rework of the conntrack expectation timeout strategy to deal with
a possible race when removing an expectation.
1) Fix the incorrect flowtable timeout extension for entries in
hw offload, from Adrian Bente. This is correcting a defect in
the functionality, no crash.
2) Hold reference to device under the fake dst in br_netfilter,
from Haoze Xie. This is fixing a possible UaF if the device
is removed while packet is sitting in nfqueue.
3) Reject template conntrack in xt_cluster, otherwise access to
uninitialize conntrack fields are possible leading to WARN_ON
due to unset layer 3 protocol. From Wyatt Feng.
4) Make sure the IPv6 tunnel header is in the linear skb data
area before pulling. While at it remove incomplete NEXTHDR_DEST
support. From Lorenzo Bianconi. This possibly leading to crash
if IPv4 header is not in the linear area.
5) Use test_bit_acquire in ipset hash set to avoid reordering
of subsequent memory access. This is addressing a LLM related
report, no crash has been observed. From Jozsef Kadlecsik.
6) Use test_bit_acquire in ipset bitmap set too, for the same
reason as in the previous patch, from Jozsef Kadlecsik.
7) Call kfree_rcu() after rcu_assign_pointer() to address a
possible UaF if kfree_rcu() runs inmediately, which to my
understanding never happens. Never observed in practise,
reported by LLM. Also from Jozsef Kadlecsik.
8) Use disable_delayed_work_sync() instead cancel_delayed_work_sync()
to avoid that ipset GC handler re-queues work as reported by LLM.
From Jozsef Kadlecsik. This is for correctness.
9) Restore the check in nft_payload for exceeding payloda offset
over 2^16. From Florian Westphal. This fixes a silent truncation,
not a big deal, but better be assertive and reject it.
10) Validate NFT_META_BRI_IIFHWADDR can only run from bridge
prerouting. From Florian Westphal. Harmless but it could allow
to read bytes from skb->cb.
11) Zero out destination hardware address during the flowtable
path setup, also from Florian. This is a correctness fix, LLM
points that possible infoleak can happen but topology to achieve
it is not clear.
12) Skip IPv4 options if present when building the IPV4 reject reply.
Otherwise bytes in the IPv4 options header can be sent back to
origin where the ICMP header is being expected. Again from
Florian Westphal.
13) Replace timer API for expectation by GC worker approach. This
is implicitly fixing a race between nf_ct_remove_expectations()
which might fail to remove the expectation due to timer_del()
returning false because timer has expired and callback is
being run concurrently. This fix is addressing a crash that has
been already reported with a reproducer.
14) Check if br_vlan_get_pvid_rcu() fails, otherwise possible stack
infoleak of 4-bytes. From Florian Westphal.
* tag 'nf-26-06-21' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf:
netfilter: nft_meta_bridge: fix NFT_META_BRI_IIFPVID stack leak
netfilter: nf_conntrack_expect: use conntrack GC to reap expectations
netfilter: nf_reject: skip iphdr options when looking for icmp header
netfilter: nft_flow_offload: zero device address for non-ether case
netfilter: nft_meta_bridge: add validate callback for get operations
netfilter: nft_payload: reject offsets exceeding 65535 bytes
netfilter: ipset: make sure gc is properly stopped
netfilter: ipset: fix order of kfree_rcu() and rcu_assign_pointer()
netfilter: ipset: Don't use test_bit() in lockless RCU readers in bitmap types
netfilter: ipset: Don't use test_bit() in lockless RCU readers in hash types
netfilter: flowtable: fix and simplify IP6IP6 tunnel handling
netfilter: xt_cluster: reject template conntracks in hash match

- Introduce and wire up a new alloc_flags parameter for modifying

introduce slab_alloc_context to keep function parameter bloat in

kmalloc_flags() exposes alloc_flags for mm-internal users.
- SLAB_ALLOC_NOLOCK flag is used to implement kmalloc_nolock()
behavior without relying on lack of __GFP_RECLAIM, which caused
false positives with workarounds like fd3634312a04 ("debugobject:
Make it work with deferred page initialization - again").
- SLAB_ALLOC_NO_RECURSE replaces __GFP_NO_OBJ_EXT, which could have
been removed, but pending memory allocation profiling changes in
mm tree have grown a new user - there is however a work ongoing
to replace that too, so __GFP_NO_OBJ_EXT should eventually be
removed. (Vlastimil Babka)
