1) Don't respond to ICMP_UNREACH errors with another ICMP_UNREACH
error.
2) Support fetching the current bridge ethernet address.
This allows a more flexible approach to packet redirection
on bridges without need to use hardcoded addresses. From
Fernando Fernandez Mancera.
3) Zap a few no-longer needed conditionals from ipvs packet path
and convert to READ/WRITE_ONCE to avoid KCSAN warnings.
From Zhang Tengfei.
4) Remove a no-longer-used macro argument in ipset, from Zhen Ni.

Add a userspace API to create a tee_shm object that refers to a dmabuf
reference.
Userspace registers the dmabuf file descriptor as in a tee_shm object.
The registration is completed with a tee_shm returned file descriptor.
Userspace is free to close the dmabuf file descriptor after it has been
registered since all the resources are now held via the new tee_shm
object.
Closing the tee_shm file descriptor will eventually release all
resources used by the tee_shm object when all references are released.
The new IOCTL, TEE_IOC_SHM_REGISTER_FD, supports dmabuf references to
physically contiguous memory buffers. Dmabuf references acquired from
the TEE DMA-heap can be used as protected memory for Secure Video Path
and such use cases. It depends on the TEE and the TEE driver if dmabuf
references acquired by other means can be used.
A new tee_shm flag is added to identify tee_shm objects built from a
registered dmabuf, TEE_SHM_DMA_BUF.

There are many parameters users might want to query about io_uring like
available request types or the ring sizes. This patch introduces an
interface for such slow path queries.
It was written with several requirements in mind:
- Can be used with or without an io_uring instance. Asking for supported
setup flags before creating an instance as well as qeurying info about
an already created ring are valid use cases.
- Should be moderately fast. For example, users might use it to
periodically retrieve ring attributes at runtime. As a consequence,
it should be able to query multiple attributes in a single syscall.
- Backward and forward compatible.
- Should be reasobably easy to use.
- Reduce the kernel code size for introducing new query types.
It's implemented as a new registration opcode IORING_REGISTER_QUERY.
The user passes one or more query strutctures linked together, each
represented by struct io_uring_query_hdr. The header stores common
control fields needed for processing and points to query type specific
information.
The header contains
- The query type
- The result field, which on return contains the error code for the query
- Pointer to the query type specific information
- The size of the query structure. The kernel will only populate up to
the size, which helps with backward compatibility. The kernel can also
reduce the size, so if the current kernel is older than the inteface
the user tries to use, it'll get only the supported bits.
- next_entry field is used to chain multiple queries.
Apart from common registeration syscall failures, it can only immediately
return an error code in case when the headers are incorrect or any
other addresses and invalid. That usually mean that the userspace
doesn't use the API right and should be corrected. All query type
specific errors are returned in the header's result field.
As an example, the patch adds a single query type for now, i.e.
IO_URING_QUERY_OPCODES, which tells what register / request / etc.
opcodes are supported, but there are particular plans to extend it.
Note: there is a request probing interface via IORING_REGISTER_PROBE,
but it's a mess. It requires the user to create a ring first, it only
works for requests, and requires dynamic allocations.

The previous patch introduced the internal infrastructure for handling
64-bit timestamps. This patch exposes this capability to user-space.
Define the new ioctl command SNDRV_COMPRESS_TSTAMP64, which allows
applications to fetch the overflow-safe struct snd_compr_tstamp64.
The ioctl dispatch table is updated to handle the new command by
calling a new snd_compr_tstamp64 handler, while the legacy path is
renamed to snd_compr_tstamp32 for clarity.
This patch bumps the SNDRV_COMPRESS_VERSION to 0.4.0.

The copied_total field in struct snd_compr_tstamp is a 32-bit
value that can overflow on long-running high-bitrate streams,
leading to incorrect calculations for buffer availablility.
This patch adds a 64-bit safe timestamping mechanism.
A new UAPI struct, snd_compr_tstamp64, is added which uses 64-bit
types for byte counters. The relevant ops structures across the
ASoC and core compress code are updated to use this new struct.
ASoC drivers are updated to use u64 counters.
Internal timestamps being u64 now, a compatibility function is added
to convert the 64-bit timestamp back to the 32-bit format for legacy
ioctl callers.

Some fuse servers need to prune their caches, which can only be done if the
kernel's own dentry/inode caches are pruned first to avoid dangling
references.
Add FUSE_NOTIFY_PRUNE, which takes an array of node ID's to try and get rid
of. Inodes with active references are skipped.
A similar functionality is already provided by FUSE_NOTIFY_INVAL_ENTRY with
the FUSE_EXPIRE_ONLY flag. Differences in the interface are
FUSE_NOTIFY_INVAL_ENTRY:
- can only prune one dentry
- dentry is determined by parent ID and name
- if inode has multiple aliases (cached hard links), then they would have
to be invalidated individually to be able to get rid of the inode
FUSE_NOTIFY_PRUNE:
- can prune multiple inodes
- inodes determined by their node ID
- aliases are taken care of automatically

When reporting an error, the AER driver prints the TLP Header / Prefix Log
only for errors enumerated in the AER_LOG_TLP_MASKS macro.
The macro was never amended since its introduction in 2006 with commit
6c2b374d7485 ("PCI-Express AER implemetation: AER core and aerdriver").
At the time, PCIe r1.1 was the latest spec revision.
Amend the macro with errors defined since then to avoid omitting the TLP
Header / Prefix Log for newer errors.
The order of the errors in AER_LOG_TLP_MASKS follows PCIe r1.1 sec 6.2.7
rather than 7.10.2, because only the former documents for which errors a
TLP Header / Prefix is logged. Retain this order. The section number is
still 6.2.7 in today's PCIe r7.0.
For Completion Timeouts, the TLP Header / Prefix is only logged if the
Completion Timeout Prefix / Header Log Capable bit is set in the AER
Capabilities and Control register. Introduce a tlp_header_logged() helper
to check whether the TLP Header / Prefix Log is populated and use it in
the two places which currently match against AER_LOG_TLP_MASKS directly.
For Uncorrectable Internal Errors, logging of the TLP Header / Prefix is
optional per PCIe r7.0 sec 6.2.7. If needed, drivers could indicate
through a flag whether devices are capable and tlp_header_logged() could
then check that flag.
pcitools introduced macros for newer errors with commit 144b0911cc0b
("ls-ecaps: extend decode support for more fields for AER CE and UE
status"):
https://git.kernel.org/pub/scm/utils/pciutils/pciutils.git/commit/?id=144b0911cc0b
Unfortunately some of those macros are overly long:
PCI_ERR_UNC_POISONED_TLP_EGRESS
PCI_ERR_UNC_DMWR_REQ_EGRESS_BLOCKED
PCI_ERR_UNC_IDE_CHECK
PCI_ERR_UNC_MISR_IDE_TLP
PCI_ERR_UNC_PCRC_CHECK
PCI_ERR_UNC_TLP_XLAT_EGRESS_BLOCKED
This seems unsuitable for <linux/pci_regs.h>, so shorten to:
PCI_ERR_UNC_POISON_BLK
PCI_ERR_UNC_DMWR_BLK
PCI_ERR_UNC_IDE_CHECK
PCI_ERR_UNC_MISR_IDE
PCI_ERR_UNC_PCRC_CHECK
PCI_ERR_UNC_XLAT_BLK
Note that some of the existing macros in <linux/pci_regs.h> do not match
exactly with pcitools (e.g. PCI_ERR_UNC_SDES versus PCI_ERR_UNC_SURPDN),
so it does not seem mandatory for them to be identical.

The so-called fullmac devices rely on firmware functionality and/or API to
change BSS parameters. Today there are limited drivers supporting the
nl80211 primitive, but they only handle a subset of the bss parameters
passed if any. The mac80211 driver does handle all parameters and stores
their configured values. Some of the BSS parameters were already conditional
by wiphy->features. For these the wiphy->bss_param_support and wiphy->features
fields are silently aligned in wiphy_register(). Maybe better to issue a warning
instead when they are misaligned.

An S1G TIM PVB is encoded differently compared to a non-s1g TIM PVB.
As the AP dictates which encoding mode it uses, here we only implement
block bitmap encoding. This is the default encoding mode used by
all current vendor implementations.
Additionally, S1G has a maximum AID count of 8192, however we are
limiting the current implementation to 1600. This has no resemblence
to the standard and is purely an implementation detail. The reason for
this is due to the TIM elements maximum length of 255. This allows for,
at most, 25 encoded blocks for a PVB encoded with block bitmap. Support
for the maximum of 8192 AIDs will require an implementation of page slicing
to be added to mac80211.
As a result, we perform extra validation on both the STA and AP side
when receiving an AID as an S1G interface.
Add support for block bitmap encoding for an S1G AP and limit the
maximum AID count to 1600 for the current mac80211 implementations.

This new attribute is supposed to be used instead of NFTA_DEVICE_NAME
for simple wildcard interface specs. It holds a NUL-terminated string
representing an interface name prefix to match on.
While kernel code to distinguish full names from prefixes in
NFTA_DEVICE_NAME is simpler than this solution, reusing the existing
attribute with different semantics leads to confusion between different
versions of kernel and user space though:
* With old kernels, wildcards submitted by user space are accepted yet
silently treated as regular names.
* With old user space, wildcards submitted by kernel may cause crashes
since libnftnl expects NUL-termination when there is none.
Using a distinct attribute type sanitizes these situations as the
receiving part detects and rejects the unexpected attribute nested in
*_HOOK_DEVS attributes.

FUSE_INIT has always been asynchronous with mount. That means that the
server processed this request after the mount syscall returned.
This means that FUSE_INIT can't supply the root inode's ID, hence it
currently has a hardcoded value. There are other limitations such as not
being able to perform getxattr during mount, which is needed by selinux.
To remove these limitations allow server to process FUSE_INIT while
initializing the in-core super block for the fuse filesystem. This can
only be done if the server is prepared to handle this, so add
FUSE_DEV_IOC_SYNC_INIT ioctl, which
a) lets the server know whether this feature is supported, returning
ENOTTY othewrwise.
b) lets the kernel know to perform a synchronous initialization
The implementation is slightly tricky, since fuse_dev/fuse_conn are set up
only during super block creation. This is solved by setting the private
data of the fuse device file to a special value ((struct fuse_dev *) 1) and
waiting for this to be turned into a proper fuse_dev before commecing with
operations on the device file.

-Wflex-array-member-not-at-end has been introduced in GCC-14, and we are
getting ready to enable it, globally.
So, in order to avoid ending up with a flexible-array member in the
middle of multiple other structs, we use the '__struct_group()' helper
to create a new tagged 'struct fc_df_desc_fpin_reg_hdr'. This structure
groups together all the members of the flexible 'struct
fc_df_desc_fpin_reg' except the flexible array.
As a result, the array is effectively separated from the rest of the
members without modifying the memory layout of the flexible structure.
We then change the type of the middle struct members currently causing
trouble from 'struct fc_df_desc_fpin_reg' to 'struct
fc_df_desc_fpin_reg_hdr'.
We also want to ensure that in case new members need to be added to the
flexible structure, they are always included within the newly created
tagged struct. For this, we use '_Static_assert()'. This ensures that
the memory layout for both the flexible structure and the new tagged
struct is the same after any changes.
This approach avoids having to implement 'struct fc_df_desc_fpin_reg_hdr'
as a completely separate structure, thus preventing having to maintain
two independent but basically identical structures, closing the door
to potential bugs in the future.
The above is also done for flexible structures 'struct fc_els_rdf' and
'struct fc_els_rdf_resp'
So, with these changes, fix the following warnings:
drivers/scsi/lpfc/lpfc_hw4.h:4936:41: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

For a user mode library to avoid generating SIGPIPE signals (e.g.
because this behaviour is not portable across operating systems) is
cumbersome. It is generally bad form to change the process-wide signal
mask in a library, so a local solution is needed instead.
For I/O performed directly using system calls (synchronous or readiness
based asynchronous) this currently involves applying a thread-specific
signal mask before the operation and reverting it afterwards. This can be
avoided when it is known that the file descriptor refers to neither a
pipe nor a socket, but a conservative implementation must always apply
the mask. This incurs the cost of two additional system calls. In the
case of sockets, the existing MSG_NOSIGNAL flag can be used with send.
For asynchronous I/O performed using io_uring, currently the only option
(apart from MSG_NOSIGNAL for sockets), is to mask SIGPIPE entirely in the
call to io_uring_enter. Thankfully io_uring_enter takes a signal mask, so
only a single syscall is needed. However, copying the signal mask on
every call incurs a non-zero performance penalty. Furthermore, this mask
applies to all completions, meaning that if the non-signaling behaviour
is desired only for some subset of operations, the desired signals must
be raised manually from user-mode depending on the completed operation.
Add RWF_NOSIGNAL flag for pwritev2. This flag prevents the SIGPIPE signal
from being raised when writing on disconnected pipes or sockets. The flag
is handled directly by the pipe filesystem and converted to the existing
MSG_NOSIGNAL flag for sockets.

ASPEED BMC IC has 2 different display engines. Please find AST2600's
datasheet to get detailed information.
1. VGA on PCIe
2. SoC Display (GFX)
By default, video engine (VE) will capture video from VGA. This patch
adds an option to capture video from GFX with standard ioctl,
vidioc_s_input.
An enum, aspeed_video_input, is added for this purpose.
enum aspeed_video_input {
VIDEO_INPUT_VGA = 0,
VIDEO_INPUT_GFX,
VIDEO_INPUT_MAX
};
To test this feature, you will need to enable GFX first. Please refer to
ASPEED's SDK_User_Guide, 6.3.x Soc Display driver, for more information.
In your application, you will need to use v4l2 ioctl, VIDIOC_S_INPUT, as
below to select before start streaming.
int rc;
struct v4l2_input input;
input.index = VIDEO_INPUT_GFX;
rc = ioctl(fd, VIDIOC_S_INPUT, &input);
if (rc < 0)
{
...

The uAPI stddef header includes compiler_types.h, a kernel-only
header, to make sure that kernel definitions of annotations
like __counted_by() take precedence.
There is a hack in scripts/headers_install.sh which strips includes
of compiler.h and compiler_types.h when installing uAPI headers.
While explicit handling makes sense for compiler.h, which is included
all over the uAPI, compiler_types.h is only included by stddef.h
(within the uAPI, obviously it's included in kernel code a lot).
Remove the stripping from scripts/headers_install.sh and wrap
the include of compiler_types.h in #ifdef __KERNEL__ instead.
This should be equivalent functionally, but is easier to understand
to a casual reader of the code. It also makes it easier to work
with kernel headers directly from under tools/

This adds support for setting IORING_NOP_CQE32 as a flag for a NOP
command, in which case a 32b CQE will be posted rather than a regular
one. This is the default if the ring has been setup with
IORING_SETUP_CQE32. If the ring has been setup with
IORING_SETUP_CQE_MIXED, then 16b CQEs will be posted without this flag
set, and 32b CQEs if this flag is set. For the latter case, sqe->off is
what will be posted as cqe->big_cqe[0] and sqe->addr is what will be
posted as cqe->big_cqe[1].

Normal rings support 16b CQEs for posting completions, while certain
features require the ring to be configured with IORING_SETUP_CQE32, as
they need to convey more information per completion. This, in turn,
makes ALL the CQEs be 32b in size. This is somewhat wasteful and
inefficient, particularly when only certain CQEs need to be of the
bigger variant.
This adds support for setting up a ring with mixed CQE sizes, using
IORING_SETUP_CQE_MIXED. When setup in this mode, CQEs posted to the ring
may be either 16b or 32b in size. If a CQE is 32b in size, then
IORING_CQE_F_32 is set in the CQE flags to indicate that this is the
case. If this flag isn't set, the CQE is the normal 16b variant.
CQEs on these types of mixed rings may also have IORING_CQE_F_SKIP set.
This can happen if the ring is one (small) CQE entry away from wrapping,
and an attempt is made to post a 32b CQE. As CQEs must be contigious in
the CQ ring, a 32b CQE cannot wrap the ring. For this case, a single
dummy CQE is posted with the SKIP flag set. The application should
simply ignore those.

The FUSE protocol uses struct fuse_write_out to convey the return value of
copy_file_range, which is restricted to uint32_t. But the COPY_FILE_RANGE
interface supports a 64-bit size copies and there's no reason why copies
should be limited to 32-bit.
Introduce a new op COPY_FILE_RANGE_64, which is identical, except the
number of bytes copied is returned in a 64-bit value.
If the fuse server does not support COPY_FILE_RANGE_64, fall back to
COPY_FILE_RANGE.
