Pull crypto library updates from Eric Biggers:
- Migrate more hash algorithms from the traditional crypto subsystem to
lib/crypto/
Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:
- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)
- Support these algorithms in lib/crypto/ using the AES library
and the existing arm64 assembly code
- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library
- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later
- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits
- Enable optimizations by default
- GHASH
- Migrate the standalone GHASH code into lib/crypto/
- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation to
resist cache-timing attacks and use much less memory
- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from the
crypto_shash API, as it's no longer needed
- Enable optimizations by default
- SM3
- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it
- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms
- Testing improvements:
- Add a KUnit test suite for each of the new library APIs
- Migrate the existing ChaCha20Poly1305 test to KUnit
- Make the KUnit all_tests.config enable all crypto library tests
- Move the test kconfig options to the Runtime Testing menu
- Other updates to arch-optimized crypto code:
- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine
- Remove some MD5 implementations that are no longer worth keeping
- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64
- Make jitterentropy and samples/tsm-mr use the crypto library APIs

Pull hfsplus updates from Viacheslav Dubeyko:
"This contains several fixes of syzbot reported issues and HFS+ fixes
of xfstests failures.
- Fix a syzbot reported issue of a KMSAN uninit-value in
hfsplus_strcasecmp().
The root cause was that hfs_brec_read() doesn't validate that the
on-disk record size matches the expected size for the record type
being read. The fix introduced hfsplus_brec_read_cat() wrapper that
validates the record size based on the type field and returns -EIO
if size doesn't match (Deepanshu Kartikey)
- Fix a syzbot reported issue of processing corrupted HFS+ images
where the b-tree allocation bitmap indicates that the header node
(Node 0) is free. Node 0 must always be allocated. Violating this
invariant leads to allocator corruption, which cascades into kernel
panics or undefined behavior.
Prevent trusting a corrupted allocator state by adding a validation
check during hfs_btree_open(). If corruption is detected, print a
warning identifying the specific corrupted tree and force the
filesystem to mount read-only (SB_RDONLY).
This prevents kernel panics from corrupted images while enabling
data recovery (Shardul Bankar)
- Fix a potential deadlock in hfsplus_fill_super().
hfsplus_fill_super() calls hfs_find_init() to initialize a search
structure, which acquires tree->tree_lock. If the subsequent call
to hfsplus_cat_build_key() fails, the function jumps to the
out_put_root error label without releasing the lock.
Fix this by adding the missing hfs_find_exit(&fd) call before
jumping to the out_put_root error label. This ensures that
tree->tree_lock is properly released on the error path (Zilin Guan)
- Update a files ctime after rename in hfsplus_rename() (Yangtao Li)
The rest of the patches introduce the HFS+ fixes for the case of
generic/348, generic/728, generic/533, generic/523, and generic/642
test-cases of xfstests suite"

Pull btrfs updates from David Sterba:
"User visible changes:
- move shutdown ioctl support out of experimental features, a forced
stop of filesystem operation until the next unmount; additionally
there's a super block operation to forcibly remove a device from
under the filesystem that could lead to a shutdown or not if the
redundancy allows that
- report filesystem shutdown using fserror mechanism
- tree-checker updates:
- verify free space info, extent and bitmap items
- verify remap-tree items and related data in block group items
Performance improvements:
- speed up clearing first extent in the tracked range (+10%
throughput on sample workload)
- reduce COW rewrites of extent buffers during the same transaction
- avoid taking big device lock to update device stats during
transaction commit
- fix unnecessary flush on close when truncating empty files
(observed in practice on a backup application)
- prevent direct reclaim during compressed readahead to avoid stalls
under memory pressure
Notable fixes:
- fix chunk allocation strategy on RAID1-like block groups with
disproportionate device sizes, this could lead to ENOSPC due to
skewed reservation estimates
- adjust metadata reservation overcommit ratio to be less aggressive
and also try to flush if possible, this avoids ENOSPC and potential
transaction aborts in some edge cases (that are otherwise hard to
reproduce)
- fix silent IO error in encoded writes and ordered extent split in
zoned mode, the error was not correctly propagated to the address
space and could lead to zeroed ranges
- don't mark inline files NOCOMPRESS unexpectedly, the intent was to
do that for single block writes of regular files
- fix deadlock between reflink and transaction commit when using
flushoncommit
- fix overly strict item check of a running dev-replace operation
Core:
- zoned mode space reservation fixes:
- cap delayed refs metadata reservation to avoid overcommit
- update logic to reclaim partially unusable zones
- add another state to flush and reclaim partially used zone
- limit number of zones reclaimed in one go to avoid blocking
other operations
- don't let log trees consume global reserve on overcommit and fall
back to transaction commit
- revalidate extent buffer when checking its up-to-date status
- add self tests for zoned mode block group specifics
- reduce atomic allocations in some qgroup paths
- avoid unnecessary root node COW during snapshotting
- start new transaction in block group relocation conditionally
- faster check of NOCOW files on currently snapshotted root
- change how compressed bio size is tracked from bio and reduce the
structure size
- new tracepoint for search slot restart tracking
- checksum list manipulation improvements
- type, parameter cleanups, refactoring
- error handling improvements, transaction abort call adjustments"

Pull LSM updates from Paul Moore:
"We only have five patches in the LSM tree, but three of the five are
for an important bugfix relating to overlayfs and the mmap() and
mprotect() access controls for LSMs. Highlights below:
- Fix problems with the mmap() and mprotect() LSM hooks on overlayfs
As we are dealing with problems both in mmap() and mprotect() there
are essentially two components to this fix, spread across three
patches with all marked for stable.
The simplest portion of the fix is the creation of a new LSM hook,
security_mmap_backing_file(), that is used to enforce LSM mmap()
access controls on backing files in the stacked/overlayfs case. The
existing security_mmap_file() does not have visibility past the
user file. You can see from the associated SELinux hook callback
the code is fairly straightforward.
The mprotect() fix is a bit more complicated as there is no way in
the mprotect() code path to inspect both the user and backing
files, and bolting on a second file reference to vm_area_struct
wasn't really an option.
The solution taken here adds a LSM security blob and associated
hooks to the backing_file struct that LSMs can use to capture and
store relevant information from the user file. While the necessary
SELinux information is relatively small, a single u32, I expect
other LSMs to require more than that, and a dedicated backing_file
LSM blob provides a storage mechanism without negatively impacting
other filesystems.
I want to note that other LSMs beyond SELinux have been involved in
the discussion of the fixes presented here and they are working on
their own related changes using these new hooks, but due to other
issues those patches will be coming at a later date.

Add a new getsockopt_iter callback to struct proto_ops that uses
sockopt_t, a type-safe wrapper around iov_iter. This provides a clean
interface for socket option operations that works with both user and
kernel buffers.
The sockopt_t type encapsulates an iov_iter and an optlen field.
The optlen field, although not suggested by Linus, serves as both input
(buffer size) and output (returned data size), allowing callbacks to
return random values independent of the bytes written via
copy_to_iter(), so, keep it separated from iov_iter.count.
This is preparatory work for removing the SOL_SOCKET level restriction
from io_uring getsockopt operations.
Keep in mind that both iter_out and iter_in always point to the same
data at all times, and we just have two of them to make the callback
implementation sane.

As noted in the blamed commit, the AR8035 and other PHYs from this
family advertise the Extended Next Page support by default, which may be
understood by some partners as this PHY being multi-gig capable.
The fix is to disable XNP advertising, which is done by setting bit 12
of the Auto-Negotiation Advertisement Register (MII_ADVERTISE).
The blamed commit incorrectly uses MDIO_AN_CTRL1_XNP, which is bit 13 as per
802.3 : 45.2.7.1 AN control register (Register 7.0)
BIT 12 in MII_ADVERTISE is wrapped by ADVERTISE_RESV, used by some
drivers such as the aquantia one. 802.3 Clause 28 defines bit 12 as
Extended Next Page ability, at least in recent versions of the standard.
Let's add a define for it and use it in the at803x driver.

Pull clone and pidfs updates from Christian Brauner:
"Add three new clone3() flags for pidfd-based process lifecycle
management.
CLONE_AUTOREAP:
CLONE_AUTOREAP makes a child process auto-reap on exit without ever
becoming a zombie. This is a per-process property in contrast to
the existing auto-reap mechanism via SA_NOCLDWAIT or SIG_IGN for
SIGCHLD which applies to all children of a given parent.
Currently the only way to automatically reap children is to set
SA_NOCLDWAIT or SIG_IGN on SIGCHLD. This is a parent-scoped
property affecting all children which makes it unsuitable for
libraries or applications that need selective auto-reaping of
specific children while still being able to wait() on others.
CLONE_AUTOREAP stores an autoreap flag in the child's
signal_struct. When the child exits do_notify_parent() checks this
flag and causes exit_notify() to transition the task directly to
EXIT_DEAD. Since the flag lives on the child it survives
reparenting: if the original parent exits and the child is
reparented to a subreaper or init the child still auto-reaps when
it eventually exits. This is cleaner than forcing the subreaper to
get SIGCHLD and then reaping it. If the parent doesn't care the
subreaper won't care. If there's a subreaper that would care it
would be easy enough to add a prctl() that either just turns back
on SIGCHLD and turns off auto-reaping or a prctl() that just
notifies the subreaper whenever a child is reparented to it.
CLONE_AUTOREAP can be combined with CLONE_PIDFD to allow the parent
to monitor the child's exit via poll() and retrieve exit status via
PIDFD_GET_INFO. Without CLONE_PIDFD it provides a fire-and-forget
pattern. No exit signal is delivered so exit_signal must be zero.
CLONE_THREAD and CLONE_PARENT are rejected: CLONE_THREAD because
autoreap is a process-level property, and CLONE_PARENT because an
autoreap child reparented via CLONE_PARENT could become an
invisible zombie under a parent that never calls wait().
The flag is not inherited by the autoreap process's own children.
Each child that should be autoreaped must be explicitly created
with CLONE_AUTOREAP.
CLONE_NNP:
CLONE_NNP sets no_new_privs on the child at clone time. Unlike
prctl(PR_SET_NO_NEW_PRIVS) which a process sets on itself,
CLONE_NNP allows the parent to impose no_new_privs on the child at
creation without affecting the parent's own privileges.
CLONE_THREAD is rejected because threads share credentials.
CLONE_NNP is useful on its own for any spawn-and-sandbox pattern
but was specifically introduced to enable unprivileged usage of
CLONE_PIDFD_AUTOKILL.
CLONE_PIDFD_AUTOKILL:
This flag ties a child's lifetime to the pidfd returned from
clone3(). When the last reference to the struct file created by
clone3() is closed the kernel sends SIGKILL to the child. A pidfd
obtained via pidfd_open() for the same process does not keep the
child alive and does not trigger autokill - only the specific
struct file from clone3() has this property. This is useful for
container runtimes, service managers, and sandboxed subprocess
execution - any scenario where the child must die if the parent
crashes or abandons the pidfd or just wants a throwaway helper
process.
CLONE_PIDFD_AUTOKILL requires both CLONE_PIDFD and CLONE_AUTOREAP.
It requires CLONE_PIDFD because the whole point is tying the
child's lifetime to the pidfd. It requires CLONE_AUTOREAP because a
killed child with no one to reap it would become a zombie - the
primary use case is the parent crashing or abandoning the pidfd so
no one is around to call waitpid(). CLONE_THREAD is rejected
because autokill targets a process not a thread.
If CLONE_NNP is specified together with CLONE_PIDFD_AUTOKILL an
unprivileged user may spawn a process that is autokilled. The child
cannot escalate privileges via setuid/setgid exec after being
spawned. If CLONE_PIDFD_AUTOKILL is specified without CLONE_NNP the
caller must have have CAP_SYS_ADMIN in its user namespace"

Pull vfs i_ino updates from Christian Brauner:
"For historical reasons, the inode->i_ino field is an unsigned long,
which means that it's 32 bits on 32 bit architectures. This has caused
a number of filesystems to implement hacks to hash a 64-bit identifier
into a 32-bit field, and deprives us of a universal identifier field
for an inode.
This changes the inode->i_ino field from an unsigned long to a u64.
This shouldn't make any material difference on 64-bit hosts, but
32-bit hosts will see struct inode grow by at least 4 bytes. This
could have effects on slabcache sizes and field alignment.
The bulk of the changes are to format strings and tracepoints, since
the kernel itself doesn't care that much about the i_ino field. The
first patch changes some vfs function arguments, so check that one out
carefully.
With this change, we may be able to shrink some inode structures. For
instance, struct nfs_inode has a fileid field that holds the 64-bit
inode number. With this set of changes, that field could be
eliminated. I'd rather leave that sort of cleanups for later just to
keep this simple"

The FRWR registration path converts data through three
representations: xdr_buf -> rpcrdma_mr_seg[] -> scatterlist[]
-> ib_map_mr_sg(). The rpcrdma_mr_seg intermediate is a relic
of when multiple registration strategies existed (FMR, physical,
FRWR). Only FRWR remains, so this indirection and the 6240-byte
rl_segments[260] array embedded in each rpcrdma_req serve no
purpose.
Introduce struct rpcrdma_xdr_cursor to track position within
an xdr_buf during iterative MR registration. Rewrite frwr_map to
populate scatterlist entries directly from the xdr_buf regions
(head kvec, page list, tail kvec). The boundary logic for
non-SG_GAPS devices is simpler because the xdr_buf structure
guarantees that page-region entries after the first start at
offset 0, and that head/tail kvecs are separate regions that
naturally break at MR boundaries.
Fix a pre-existing bug in rpcrdma_encode_write_list where the
write-pad statistics accumulator added mr->mr_length from the last
data MR rather than the write-pad MR. The refactored code uses
ep->re_write_pad_mr->mr_length.

xprt_rdma_alloc_slot() and xprt_rdma_free_slot() lack serialization
between the buffer pool and the backlog queue. A buffer freed
after rpcrdma_buffer_get() finds the pool empty but before
rpc_sleep_on() places the task on the backlog is returned to the
pool with no waiter to wake, leaving the task stuck on the backlog
indefinitely.
After joining the backlog, re-check the pool and route any
recovered buffer through xprt_wake_up_backlog(), whose queue lock
serializes with concurrent wakeups and avoids double-assignment
of slots.
Because xprt_rdma_free_slot() does not hold reserve_lock, the
XPRT_CONGESTED double-check in xprt_throttle_congested() is
ineffective: a task can join the backlog through that path after
free_slot has already found it empty and cleared the bit. Avoid
this by using xprt_add_backlog_noncongested(), which queues the
task without setting XPRT_CONGESTED, so every allocation reaches
xprt_rdma_alloc_slot() and its post-sleep re-check.

xfstest generic/728 fails with delegated timestamps. The client does a
removexattr and then a stat to test the ctime, which doesn't change. The
stat() doesn't trigger a GETATTR because of the delegated timestamps, so
it relies on the cached ctime, which is wrong.
The setxattr compound has a trailing GETATTR, which ensures that its
ctime gets updated. Follow the same strategy with removexattr.

Pull vfs integrity updates from Christian Brauner:
"This adds support to generate and verify integrity information (aka
T10 PI) in the file system, instead of the automatic below the covers
support that is currently used.
The implementation is based on refactoring the existing block layer PI
code to be reusable for this use case, and then adding relatively
small wrappers for the file system use case. These are then used in
iomap to implement the semantics, and wired up in XFS with a small
amount of glue code.
Compared to the baseline this does not change performance for writes,
but increases read performance up to 15% for 4k I/O, with the benefit
decreasing with larger I/O sizes as even the baseline maxes out the
device quickly on my older enterprise SSD"

Pull vfs directory updates from Christian Brauner:
"Recently 'start_creating', 'start_removing', 'start_renaming' and
related interfaces were added which combine the locking and the
lookup.
At that time many callers were changed to use the new interfaces.
However there are still an assortment of places out side of the core
vfs where the directory is locked explictly, whether with inode_lock()
or lock_rename() or similar. These were missed in the first pass for
an assortment of uninteresting reasons.
This addresses the remaining places where explicit locking is used,
and changes them to use the new interfaces, or otherwise removes the
explicit locking.
The biggest changes are in overlayfs. The other changes are quite
simple, though maybe the cachefiles changes is the least simple of
those"

Pull vfs xattr updates from Christian Brauner:
"This reworks the simple_xattr infrastructure and adds support for
user.* extended attributes on sockets.
The simple_xattr subsystem currently uses an rbtree protected by a
reader-writer spinlock. This series replaces the rbtree with an
rhashtable giving O(1) average-case lookup with RCU-based lockless
reads. This sped up concurrent access patterns on tmpfs quite a bit
and it's an overall easy enough conversion to do and gets rid or
rwlock_t.
The conversion is done incrementally: a new rhashtable path is added
alongside the existing rbtree, consumers are migrated one at a time
(shmem, kernfs, pidfs), and then the rbtree code is removed. All three
consumers switch from embedded structs to pointer-based lazy
allocation so the rhashtable overhead is only paid for inodes that
actually use xattrs.
With this infrastructure in place the series adds support for user.*
xattrs on sockets. Path-based AF_UNIX sockets inherit xattr support
from the underlying filesystem (e.g. tmpfs) but sockets in sockfs -
that is everything created via socket() including abstract namespace
AF_UNIX sockets - had no xattr support at all.
The xattr_permission() checks are reworked to allow user.* xattrs on
S_IFSOCK inodes. Sockfs sockets get per-inode limits of 128 xattrs and
128KB total value size matching the limits already in use for kernfs.
The practical motivation comes from several directions. systemd and
GNOME are expanding their use of Varlink as an IPC mechanism.
For D-Bus there are tools like dbus-monitor that can observe IPC
traffic across the system but this only works because D-Bus has a
central broker.
For Varlink there is no broker and there is currently no way to
identify which sockets speak Varlink. With user.* xattrs on sockets a
service can label its socket with the IPC protocol it speaks (e.g.,
user.varlink=1) and an eBPF program can then selectively capture
traffic on those sockets. Enumerating bound sockets via netlink
combined with these xattr labels gives a way to discover all Varlink
IPC entrypoints for debugging and introspection.
Similarly, systemd-journald wants to use xattrs on the /dev/log socket
for protocol negotiation to indicate whether RFC 5424 structured
syslog is supported or whether only the legacy RFC 3164 format should
be used.
In containers these labels are particularly useful as high-privilege
or more complicated solutions for socket identification aren't
available.
The series comes with comprehensive selftests covering path-based
AF_UNIX sockets, sockfs socket operations, per-inode limit
enforcement, and xattr operations across multiple address families
(AF_INET, AF_INET6, AF_NETLINK, AF_PACKET)"

KVM SVM changes for 7.1
- Fix and optimize IRQ window inhibit handling for AVIC (the tracking needs to
be per-vCPU, e.g. so that KVM doesn't prematurely re-enable AVIC if multiple
vCPUs have to-be-injected IRQs).
- Fix an undefined behavior warning where a crafty userspace can read the
"avic" module param before it's fully initialized.
- Fix a (likely benign) bug in the "OS-visible workarounds" handling, where
KVM could clobber state when enabling virtualization on multiple CPUs in
parallel, and clean up and optimize the code.
- Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a
"too large" size based purely on user input, and clean up and harden the
related pinning code.
- Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as
doing so for an SNP guest will trigger an RMP violation #PF and crash the
host.
- Protect all of sev_mem_enc_register_region() with kvm->lock to ensure
sev_guest() is stable for the entire of the function.
- Lock all vCPUs when synchronizing VMSAs for SNP guests to ensure the VMSA
page isn't actively being used.
- Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries are
required to hold kvm->lock (KVM has had multiple bugs due "is SEV?" checks
becoming stale), enforced by lockdep. Add and use vCPU-scoped APIs when
possible/appropriate, as all checks that originate from a vCPU are
guaranteed to be stable.
- Convert a pile of kvm->lock SEV code to guard().

Since the panel/bridge should logically be positioned behind the
Analogix bridge in the display pipeline, it makes sense to handle
the panel/bridge parsing on the Analogix side. Therefore, we add
a new API analogix_dp_finish_probe(), which combines the panel/bridge
parsing with component addition, to do it.
In order to process component binding right after the probe completes,
the &analogix_dp_plat_data.ops is newly added to pass &component_ops,
for which the &dp_aux_ep_device_with_data.done_probing() of DP AUX bus
only supports passing &drm_dp_aux.

This series cleans up some of the special user copy functions naming and
semantics. In particular, get rid of the (very traditional) double
underscore names and behavior: the whole "optimize away the range check"
model has been largely excised from the other user accessors because
it's so subtle and can be unsafe, but also because it's just not a
relevant optimization any more.
To do that, a couple of drivers that misused the "user" copies as kernel
copies in order to get non-temporal stores had to be fixed up, but that
kind of code should never have been allowed anyway.
The x86-only "nocache" version was also renamed to more accurately
reflect what it actually does.
This was all done because I looked at this code due to a report by Jann
Horn, and I just couldn't stand the inconsistent naming, the horrible
semantics, and the random misuse of these functions. This code should
probably be cleaned up further, but it's at least slightly closer to
normal semantics.
I had a more intrusive series that went even further in trying to
normalize the semantics, but that ended up hitting so many other
inconsistencies between different architectures in this area (eg
'size_t' vs 'unsigned long' vs 'int' as size arguments, and various
iovec check differences that Vasily Gorbik pointed out) that I ended up
with this more limited version that fixed the worst of the issues.

Commit under Fixes moved recomputing the window clamp to
tcp_measure_rcv_mss() (when scaling_ratio changes).
I suspect it missed the fact that we don't recompute the clamp
when rcvbuf is set. Until scaling_ratio changes we are
stuck with the old window clamp which may be based on
the small initial buffer. scaling_ratio may never change.
Inspired by Eric's recent commit d1361840f8c5 ("tcp: fix
SO_RCVLOWAT and RCVBUF autotuning") plumb the user action
thru to TCP and have it update the clamp.
A smaller fix would be to just have tcp_rcvbuf_grow()
adjust the clamp even if SOCK_RCVBUF_LOCK is set.
But IIUC this is what we were trying to get away from
in the first place.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
struct hci_std_codecs and struct hci_std_codecs_v2 are flexible
structures, this is structures that contain a flexible-array member
(__u8 codec[]; and struct hci_std_codec_v2 codec[];, correspondingly.)
Since struct hci_rp_read_local_supported_codecs and struct
hci_rp_read_local_supported_codecs_v2 are defined by hardware, we
create the new struct hci_std_codecs_hdr and struct hci_std_codecs_v2_hdr
types, and use them to replace the object types causing trouble in
struct hci_rp_read_local_supported_codecs and struct
hci_rp_read_local_supported_codecs_v2, namely struct hci_std_codecs
std_codecs; and struct hci_std_codecs_v2_hdr std_codecs;.
Also, once -fms-extensions is enabled, we can use transparent struct
members in both struct hci_std_codecs and struct hci_std_codecs_v2_hdr.
Notice that the newly created types does not contain the flex-array
member `codec`, which is the object causing the -Wfamnae warnings.
After these changes, the size of struct hci_rp_read_local_supported_codecs
and struct hci_rp_read_local_supported_codecs_v2, along with their
member's offsets remain the same, hence the memory layouts don't
change:
Before changes:
struct hci_rp_read_local_supported_codecs {
__u8 status; /* 0 1 */
struct hci_std_codecs std_codecs; /* 1 1 */
struct hci_vnd_codecs vnd_codecs; /* 2 1 */
/* size: 3, cachelines: 1, members: 3 */
/* last cacheline: 3 bytes */
} __attribute__((__packed__));
struct hci_rp_read_local_supported_codecs_v2 {
__u8 status; /* 0 1 */
struct hci_std_codecs_v2 std_codecs; /* 1 1 */
struct hci_vnd_codecs_v2 vendor_codecs; /* 2 1 */
/* size: 3, cachelines: 1, members: 3 */
/* last cacheline: 3 bytes */
} __attribute__((__packed__));
