wireless-next patches for v6.13
The first -next "new features" pull request for v6.13. This is a big one as we have not been able to send one earlier. We have also some patches affecting other subsystems: in staging we deleted the rtl8192e driver and in debugfs added a new interface to save struct file_operations memory; both were acked by GregKH. Because of the lib80211/libipw move there were quite a lot of conflicts and to solve those we decided to merge net-next into wireless-next. Currently there's one conflict in Documentation/networking/net_cachelines/net_device.rst. To fix that just remove the iw_public_data line: https://lore.kernel.org/all/20241011121014.674661a0@canb.auug.org.au/ And when net is merged to net-next there will be another simple conflict in in net/mac80211/cfg.c: https://lore.kernel.org/all/20241024115523.4cd35dde@canb.auug.org.au/ Major changes: cfg80211/mac80211 * stop exporting wext symbols * new mac80211 op to indicate that a new interface is to be added * support radio separation of multi-band devices Wireless Extensions * move wext spy implementation to libiw * remove iw_public_data from struct net_device brcmfmac * optional LPO clock support ipw2x00 * move remaining lib80211 code into libiw wilc1000 * WILC3000 support rtw89 * RTL8852BE and RTL8852BE-VT BT-coexistence improvements -----BEGIN PGP SIGNATURE----- iQFFBAABCgAvFiEEiBjanGPFTz4PRfLobhckVSbrbZsFAmcbz9YRHGt2YWxvQGtl cm5lbC5vcmcACgkQbhckVSbrbZsabQf8CWJ/kyonw/Z8hRxgfE/7D6Jiqoq7R+ML 8W8lbc6F5wra4eCBq/oo6UVV36Ss6mxQYcRcmLq+nCkXa4qdMpg/z55QECMHxx5Z YnIBbD2vBrIj7W21gfCKH1WJ+b5IQFZl3zuxuCgXjxD9TJM2CjUfOkvrhrqqzrPn clfUx5f01vfv2jdvClPR5977gFE5One/ANeRQNs7uDS0TeeD2P+61DEB1//htIJo 7GwwCyUJCeOcfWRMzQwhpoppWKcPAV70kSVJrl/fRstS68vQGSQbcx9yiNeWkSFw JXjQGdc8eYLPzLqECwS0KwFkta6AXbafAYYXe1wdlAzr+kmJ9x5oqA== =x+mr -----END PGP SIGNATURE----- Merge tag 'wireless-next-2024-10-25' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next Kalle Valo says: ==================== wireless-next patches for v6.13 The first -next "new features" pull request for v6.13.

io_uring: add support for fixed wait regions
Generally applications have 1 or a few waits of waiting, yet they pass
in a struct io_uring_getevents_arg every time. This needs to get copied
and, in turn, the timeout value needs to get copied.
Rather than do this for every invocation, allow the application to
register a fixed set of wait regions that can simply be indexed when
asking the kernel to wait on events.
At ring setup time, the application can register a number of these wait
regions and initialize region/index 0 upfront:
struct io_uring_reg_wait *reg;
reg = io_uring_setup_reg_wait(ring, nr_regions, &ret);
/* set timeout and mark as set, sigmask/sigmask_sz as needed */
reg->ts.tv_sec = 0;
reg->ts.tv_nsec = 100000;
reg->flags = IORING_REG_WAIT_TS;
where nr_regions >= 1 && nr_regions <= PAGE_SIZE / sizeof(*reg). The
above initializes index 0, but 63 other regions can be initialized,
if needed. Now, instead of doing:
struct __kernel_timespec timeout = { .tv_nsec = 100000, };
io_uring_submit_and_wait_timeout(ring, &cqe, nr, &t, NULL);
to wait for events for each submit_and_wait, or just wait, operation, it
can just reference the above region at offset 0 and do:
io_uring_submit_and_wait_reg(ring, &cqe, nr, 0);
to achieve the same goal of waiting 100usec without needing to copy
both struct io_uring_getevents_arg (24b) and struct __kernel_timeout
(16b) for each invocation. Struct io_uring_reg_wait looks as follows:
struct io_uring_reg_wait {
struct __kernel_timespec ts;
__u32 min_wait_usec;
__u32 flags;
__u64 sigmask;
__u32 sigmask_sz;
__u32 pad[3];
__u64 pad2[2];
};
embedding the timeout itself in the region, rather than passing it as
a pointer as well. Note that the signal mask is still passed as a
pointer, both for compatability reasons, but also because there doesn't
seem to be a lot of high frequency waits scenarios that involve setting
and resetting the signal mask for each wait.
The application is free to modify any region before a wait call, or it
can use keep multiple regions with different settings to avoid needing to
modify the same one for wait calls. Up to a page size of regions is mapped
by default, allowing PAGE_SIZE / 64 available regions for use.
The registered region must fit within a page. On a 4kb page size system,
that allows for 64 wait regions if a full page is used, as the size of
struct io_uring_reg_wait is 64b. The region registered must be aligned
to io_uring_reg_wait in size. It's valid to register less than 64
entries.
In network performance testing with zero-copy, this reduced the time
spent waiting on the TX side from 3.12% to 0.3% and the RX side from 4.4%
to 0.3%.
Wait regions are fixed for the lifetime of the ring - once registered,
they are persistent until the ring is torn down. The regions support
minimum wait timeout as well as the regular waits.

io_uring/register: add IORING_REGISTER_RESIZE_RINGS
Once a ring has been created, the size of the CQ and SQ rings are fixed. Usually this isn't a problem on the SQ ring side, as it merely controls the available number of requests that can be submitted in a single system call, and there's rarely a need to change that. For the CQ ring, it's a different story. For most efficient use of io_uring, it's important that the CQ ring never overflows. This means that applications must size it for the worst case scenario, which can be wasteful. Add IORING_REGISTER_RESIZE_RINGS, which allows an application to resize the existing rings. It takes a struct io_uring_params argument, the same one which is used to setup the ring initially, and resizes rings according to the sizes given. Certain properties are always inherited from the original ring setup, like SQE128/CQE32 and other setup options. The implementation only allows flag associated with how the CQ ring is sized and clamped. Existing unconsumed SQE and CQE entries are copied as part of the process. If either the SQ or CQ resized destination ring cannot hold the entries already present in the source rings, then the operation is failed with -EOVERFLOW. Any register op holds ->uring_lock, which prevents new submissions, and the internal mapping holds the completion lock as well across moving CQ ring state. To prevent races between mmap and ring resizing, add a mutex that's solely used to serialize ring resize and mmap. mmap_sem can't be used here, as as fork'ed process may be doing mmaps on the ring as well. The ctx->resize_lock is held across mmap operations, and the resize will grab it before swapping out the already mapped new data. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

io_uring/msg_ring: add support for sending a sync message
Normally MSG_RING requires both a source and a destination ring. But some users don't always have a ring avilable to send a message from, yet they still need to notify a target ring. Add support for using io_uring_register(2) without having a source ring, using a file descriptor of -1 for that. Internally those are called blind registration opcodes. Implement IORING_REGISTER_SEND_MSG_RING as a blind opcode, which simply takes an sqe that the application can put on the stack and use the normal liburing helpers to initialize it. Then the app can call: io_uring_register(-1, IORING_REGISTER_SEND_MSG_RING, &sqe, 1); and get the same behavior in terms of the target, where a CQE is posted with the details given in the sqe. For now this takes a single sqe pointer argument, and hence arg must be set to that, and nr_args must be 1. Could easily be extended to take an array of sqes, but for now let's keep it simple.

xfrm: Add support for per cpu xfrm state handling.
Currently all flows for a certain SA must be processed by the same cpu to avoid packet reordering and lock contention of the xfrm state lock. To get rid of this limitation, the IETF standardized per cpu SAs in RFC 9611. This patch implements the xfrm part of it. We add the cpu as a lookup key for xfrm states and a config option to generate acquire messages for each cpu. With that, we can have on each cpu a SA with identical traffic selector so that flows can be processed in parallel on all cpus.

In error path check for -EOPNOTSUPP and try to allocate non-PASID domain so that DMA-API mode work fine for drivers which does not support PASID as well.

UAPI/ioctl: Improve parameter name of ioctl request definition helpers
The third parameter to _IOR et al is a type name, not a size. So the parameter being named "size" is irritating. Rename it to "argtype" instead to reduce confusion. There is a very minor chance that this breaks stuff. It only hurts however if there is a variable (or macro) in userspace that is called "argtype" *and* it's used in the parameters of _IOR and friends. IMHO this is negligible because usually definitions making use of these macros are provided by kernel headers (i.e. us) or if they are replicated in userspace code, they are replicated and so supposed to match the kernel definitions (e.g. to make them usable by programs without the need to update the kernel headers used to compile the program).

pidfd: add ioctl to retrieve pid info
A common pattern when using pid fds is having to get information about the process, which currently requires /proc being mounted, resolving the fd to a pid, and then do manual string parsing of /proc/N/status and friends. This needs to be reimplemented over and over in all userspace projects (e.g.: I have reimplemented resolving in systemd, dbus, dbus-daemon, polkit so far), and requires additional care in checking that the fd is still valid after having parsed the data, to avoid races. Having a programmatic API that can be used directly removes all these requirements, including having /proc mounted. As discussed at LPC24, add an ioctl with an extensible struct so that more parameters can be added later if needed. Start with returning pid/tgid/ppid and creds unconditionally, and cgroupid optionally.

drm/xe/oa/uapi: Define and parse OA sync properties
Now that we have laid the groundwork, introduce OA sync properties in the
uapi and parse the input xe_sync array as is done elsewhere in the
driver. Also add DRM_XE_OA_CAPS_SYNCS bit in OA capabilities for userspace.
v2: Fix and document DRM_XE_SYNC_TYPE_USER_FENCE for OA (Matt B)

wifi: cfg80211: report per wiphy radio antenna mask
With multi-radio devices, each radio typically gets a fixed set of antennas. In order to be able to disable specific antennas for some radios, user space needs to know which antenna mask bits are assigned to which radio.

wifi: cfg80211: add option for vif allowed radios
This allows users to prevent a vif from affecting radios other than the configured ones. This can be useful in cases where e.g. an AP is running on one radio, and triggering a scan on another radio should not disturb it. Changing the allowed radios list for a vif is supported, but only while it is down. While it is possible to achieve the same by always explicitly specifying a frequency list for scan requests and ensuring that the wrong channel/band is never accidentally set on an unrelated interface, this change makes multi-radio wiphy setups a lot easier to deal with for CLI users. By itself, this patch only enforces the radio mask for scanning requests and remain-on-channel. Follow-up changes build on this to limit configured frequencies.

ublk: support device recovery without I/O queueing
ublk currently supports the following behaviors on ublk server exit: A: outstanding I/Os get errors, subsequently issued I/Os get errors B: outstanding I/Os get errors, subsequently issued I/Os queue C: outstanding I/Os get reissued, subsequently issued I/Os queue and the following behaviors for recovery of preexisting block devices by a future incarnation of the ublk server: 1: ublk devices stopped on ublk server exit (no recovery possible) 2: ublk devices are recoverable using start/end_recovery commands The userspace interface allows selection of combinations of these behaviors using flags specified at device creation time, namely: default behavior: A + 1 UBLK_F_USER_RECOVERY: B + 2 UBLK_F_USER_RECOVERY|UBLK_F_USER_RECOVERY_REISSUE: C + 2 The behavior A + 2 is currently unsupported.

fanotify: allow reporting errors on failure to open fd
When working in "fd mode", fanotify_read() needs to open an fd from a dentry to report event->fd to userspace. Opening an fd from dentry can fail for several reasons. For example, when tasks are gone and we try to open their /proc files or we try to open a WRONLY file like in sysfs or when trying to open a file that was deleted on the remote network server. Add a new flag FAN_REPORT_FD_ERROR for fanotify_init(). For a group with FAN_REPORT_FD_ERROR, we will send the event with the error instead of the open fd, otherwise userspace may not get the error at all. For an overflow event, we report -EBADF to avoid confusing FAN_NOFD with -EPERM. Similarly for pidfd open errors we report either -ESRCH or the open error instead of FAN_NOPIDFD and FAN_EPIDFD. In any case, userspace will not know which file failed to open, so add a debug print for further investigation.

thermal: core: Add user thresholds support
The user thresholds mechanism is a way to have the userspace to tell the thermal framework to send a notification when a temperature limit is crossed. There is no id, no hysteresis, just the temperature and the direction of the limit crossing. That means we can be notified when a threshold is crossed the way up only, or the way down only or both ways. That allows to create hysteresis values if it is needed. A threshold can be added, deleted or flushed. The latter means all thresholds belonging to a thermal zone will be deleted. When a threshold is added: - if the same threshold (temperature and direction) exists, an error is returned - if a threshold is specified with the same temperature but a different direction, the specified direction is added - if there is no threshold with the same temperature then it is created When a threshold is deleted: - if the same threshold (temperature and direction) exists, it is deleted - if a threshold is specified with the same temperature but a different direction, the specified direction is removed - if there is no threshold with the same temperature, then an error is returned When the threshold are flushed: - All thresholds related to a thermal zone are deleted When a threshold is crossed: - the userspace does not need to know which threshold(s) have been crossed, it will be notified with the current temperature and the previous temperature - if multiple thresholds have been crossed between two updates only one notification will be send to the userspace, it is pointless to send a notification per thresholds crossed as the userspace can handle that easily when it has the temperature delta information Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://patch.msgid.link/20240923100005.2532430-2-daniel.lezcano@linaro.org [ rjw: Subject edit, use BIT(0) and BIT(1) in symbol definitions ] Signed-off-by: Rafael J.

ptp: Add support for the AMZNC10C 'vmclock' device
The vmclock device addresses the problem of live migration with precision clocks. The tolerances of a hardware counter (e.g. TSC) are typically around ±50PPM. A guest will use NTP/PTP/PPS to discipline that counter against an external source of 'real' time, and track the precise frequency of the counter as it changes with environmental conditions. When a guest is live migrated, anything it knows about the frequency of the underlying counter becomes invalid. It may move from a host where the counter running at -50PPM of its nominal frequency, to a host where it runs at +50PPM. There will also be a step change in the value of the counter, as the correctness of its absolute value at migration is limited by the accuracy of the source and destination host's time synchronization. In its simplest form, the device merely advertises a 'disruption_marker' which indicates that the guest should throw away any NTP synchronization it thinks it has, and start again. Because the shared memory region can be exposed all the way to userspace through the /dev/vmclock0 node, applications can still use time from a fast vDSO 'system call', and check the disruption marker to be sure that their timestamp is indeed truthful. The structure also allows for the precise time, as known by the host, to be exposed directly to guests so that they don't have to wait for NTP to resync from scratch. The PTP driver consumes this information if present. Like the KVM PTP clock, this PTP driver can convert TSC-based cross timestamps into KVM clock values. Unlike the KVM PTP clock, it does so only when such is actually helpful. The values and fields are based on the nascent virtio-rtc specification, and the intent is that a version (hopefully precisely this version) of this structure will be included as an optional part of that spec. In the meantime, this driver supports the simple ACPI form of the device which is being shipped in certain commercial hypervisors (and submitted for inclusion in QEMU).

drm/xe/ptl: L3bank mask is not available on the media GT
On PTL platforms with media version 30.00, the fuse registers for reporting L3 bank availability to the GT just read out as ~0 and do not provide proper values. Xe does not use the L3 bank mask for anything internally; it only passes the mask through to userspace via the GT topology query. Since we don't have any way to get the real L3 bank mask, we don't want to pass garbage to userspace. Passing a zeroed mask or a copy of the primary GT's L3 bank mask would also be inaccurate and likely to cause confusion for userspace. The best approach is to simply not include L3 in the list of masks returned by the topology query in cases where we aren't able to provide a meaningful value. This won't change the behavior for any existing platforms (where we can always obtain L3 masks successfully for all GTs), it will only prevent us from mis-reporting bad information on upcoming platform(s). There's a good chance this will become a formal workaround in the future, but for now we don't have a lineage number so "no_media_l3" is used in place of a lineage as the OOB workaround descriptor. v2: - Re-calculate query size to properly match data returned. (Gustavo) - Update kerneldoc to clarify that the L3bank mask may not be included in the query results if the hardware doesn't make it available.

netkit: Add option for scrubbing skb meta data
Jordan reported that when running Cilium with netkit in per-endpoint-routes
mode, network policy misclassifies traffic. In this direct routing mode
of Cilium which is used in case of GKE/EKS/AKS, the Pod's BPF program to
enforce policy sits on the netkit primary device's egress side.
The issue here is that in case of netkit's netkit_prep_forward(), it will
clear meta data such as skb->mark and skb->priority before executing the
BPF program. Thus, identity data stored in there from earlier BPF programs
(e.g. from tcx ingress on the physical device) gets cleared instead of
being made available for the primary's program to process. While for traffic
egressing the Pod via the peer device this might be desired, this is
different for the primary one where compared to tcx egress on the host
veth this information would be available.
To address this, add a new parameter for the device orchestration to
allow control of skb->mark and skb->priority scrubbing, to make the two
accessible from BPF (and eventually leave it up to the program to scrub).
By default, the current behavior is retained. For netkit peer this also
enables the use case where applications could cooperate/signal intent to
the BPF program.
Note that struct netkit has a 4 byte hole between policy and bundle which
is used here, in other words, struct netkit's first cacheline content used
in fast-path does not get moved around.

At the same time, prepare for the coming implementation by GCC and Clang
of the __counted_by attribute. Flexible array members annotated with
__counted_by can have their accesses bounds-checked at run-time via
CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for
strcpy/memcpy-family functions). In this case, it is important to note
that the attribute used is specifically __counted_by_be since variable
"num_vlan" is of type __be16.
The following change to the "batadv_tt_tvlv_ogm_handler_v1" function:
- tt_vlan = (struct batadv_tvlv_tt_vlan_data *)(tt_data + 1);
- tt_change = (struct batadv_tvlv_tt_change *)(tt_vlan + num_vlan);
+ tt_change = (struct batadv_tvlv_tt_change *)((void *)tt_data
+ + flex_size);
is intended to prevent the compiler from generating an "out-of-bounds"
notification due to the __counted_by attribute. The compiler can do a
pointer calculation using the vlan_data flexible array memory, or in
other words, this may be calculated as an array offset, since it is the
same as:
&tt_data->vlan_data[num_vlan]
Therefore, we go past the end of the array. In other "multiple trailing
flexible array" situations, this has been solved by addressing from the
base pointer, since the compiler either knows the full allocation size
or it knows nothing about it (this case, since it came from a "void *"
function argument).
The order in which the structure batadv_tvlv_tt_data and the structure
batadv_tvlv_tt_vlan_data are defined must be swap to avoid an incomplete
type error.
Also, avoid the open-coded arithmetic in memory allocator functions [2]
using the "struct_size" macro and use the "flex_array_size" helper to
clarify some calculations, when possible.
Moreover, the new structure member also allow us to avoid the open-coded
arithmetic on pointers in some situations. Take advantage of this.
This code was detected with the help of Coccinelle, and audited and
modified manually.

crypto: virtio - Drop sign/verify operations
The virtio crypto driver exposes akcipher sign/verify operations in a
user space ABI. This blocks removal of sign/verify from akcipher_alg.
Herbert opines:
"I would say that this is something that we can break. Breaking it
is no different to running virtio on a host that does not support
these algorithms. After all, a software implementation must always
be present.
I deliberately left akcipher out of crypto_user because the API
is still in flux. We should not let virtio constrain ourselves."
https://lore.kernel.org/all/ZtqoNAgcnXnrYhZZ@gondor.apana.org.au/
"I would remove virtio akcipher support in its entirety. This API
was never meant to be exposed outside of the kernel."
https://lore.kernel.org/all/Ztqql_gqgZiMW8zz@gondor.apana.org.au/
Drop sign/verify support from virtio crypto. There's no strong reason
to also remove encrypt/decrypt support, so keep it.
A key selling point of virtio crypto is to allow guest access to crypto
accelerators on the host. So far the only akcipher algorithm supported
by virtio crypto is RSA. Dropping sign/verify merely means that the
PKCS#1 padding is now always generated or verified inside the guest,
but the actual signature generation/verification (which is an RSA
decrypt/encrypt operation) may still use an accelerator on the host.
Generating or verifying the PKCS#1 padding is cheap, so a hardware
accelerator won't be of much help there. Which begs the question
whether virtio crypto support for sign/verify makes sense at all.
It would make sense for the sign operation if the host has a security
chip to store asymmetric private keys. But the kernel doesn't even
have an asymmetric_key_subtype yet for hardware-based private keys.
There's at least one rudimentary driver for such chips (atmel-ecc.c for
ATECC508A), but it doesn't implement the sign operation. The kernel
would first have to grow support for a hardware asymmetric_key_subtype
and at least one driver implementing the sign operation before exposure
to guests via virtio makes sense.

net_sched: sch_fq: add the ability to offload pacing
Some network devices have the ability to offload EDT (Earliest Departure Time) which is the model used for TCP pacing and FQ packet scheduler. Some of them implement the timing wheel mechanism described in https://saeed.github.io/files/carousel-sigcomm17.pdf with an associated 'timing wheel horizon'. This patchs adds to FQ packet scheduler TCA_FQ_OFFLOAD_HORIZON attribute. Its value is capped by the device max_pacing_offload_horizon, added in the prior patch. It allows FQ to let packets within pacing offload horizon to be delivered to the device, which will handle the needed delay without host involvement.

net_tstamp: add SCM_TS_OPT_ID to provide OPT_ID in control message
SOF_TIMESTAMPING_OPT_ID socket option flag gives a way to correlate TX timestamps and packets sent via socket. Unfortunately, there is no way to reliably predict socket timestamp ID value in case of error returned by sendmsg. For UDP sockets it's impossible because of lockless nature of UDP transmit, several threads may send packets in parallel. In case of RAW sockets MSG_MORE option makes things complicated. More details are in the conversation [1]. This patch adds new control message type to give user-space software an opportunity to control the mapping between packets and values by providing ID with each sendmsg for UDP sockets. The documentation is also added in this patch.

prctl: arch-agnostic prctl for shadow stack
Three architectures (x86, aarch64, riscv) have announced support for
shadow stacks with fairly similar functionality. While x86 is using
arch_prctl() to control the functionality neither arm64 nor riscv uses
that interface so this patch adds arch-agnostic prctl() support to
get and set status of shadow stacks and lock the current configuation to
prevent further changes, with support for turning on and off individual
subfeatures so applications can limit their exposure to features that
they do not need. The features are:
- PR_SHADOW_STACK_ENABLE: Tracking and enforcement of shadow stacks,
including allocation of a shadow stack if one is not already
allocated.
- PR_SHADOW_STACK_WRITE: Writes to specific addresses in the shadow
stack.
- PR_SHADOW_STACK_PUSH: Push additional values onto the shadow stack.
These features are expected to be inherited by new threads and cleared
on exec(), unknown features should be rejected for enable but accepted
for locking (in order to allow for future proofing).
This is based on a patch originally written by Deepak Gupta but modified
fairly heavily, support for indirect landing pads is removed, additional
modes added and the locking interface reworked. The set status prctl()
is also reworked to just set flags, if setting/reading the shadow stack
pointer is required this could be a separate prctl.

bpf: Make sure internal and UAPI bpf_redirect flags don't overlap
The bpf_redirect_info is shared between the SKB and XDP redirect paths,
and the two paths use the same numeric flag values in the ri->flags
field (specifically, BPF_F_BROADCAST == BPF_F_NEXTHOP). This means that
if skb bpf_redirect_neigh() is used with a non-NULL params argument and,
subsequently, an XDP redirect is performed using the same
bpf_redirect_info struct, the XDP path will get confused and end up
crashing, which syzbot managed to trigger.
With the stack-allocated bpf_redirect_info, the structure is no longer
shared between the SKB and XDP paths, so the crash doesn't happen
anymore. However, different code paths using identically-numbered flag
values in the same struct field still seems like a bit of a mess, so
this patch cleans that up by moving the flag definitions together and
redefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlap
with the flags used for XDP. It also adds a BUILD_BUG_ON() check to make
sure the overlap is not re-introduced by mistake.

Char/Misc and other driver changes for 6.12-rc1
Here is the "big" set of char/misc and other driver subsystem changes for 6.12-rc1. Sorry for the delay, conference travel for the past two weeks has this and my other pull requests showing up real late in the cycle. Lots of changes in here, primarily dominated by the usual IIO driver updates and additions, but there are also small driver subsystem updates all over the place. Included in here are: - lots and lots of new IIO drivers and updates to existing ones - interconnect subsystem updates and new drivers - nvmem subsystem updates and new drivers - mhi driver updates - power supply subsystem updates - kobj_type const work for many different small subsystems - comedi driver fix - coresight subsystem and driver updates - fpga subsystem improvements - slimbus fixups - binder new feature addition for "frozen" notifications - lots and lots of other small driver updates and cleanups All of these have been in linux-next for a long time with no reported problems.

xen/privcmd: Add new syscall to get gsi from dev
On PVH dom0, when passthrough a device to domU, QEMU and xl tools want to use gsi number to do pirq mapping, see QEMU code xen_pt_realize->xc_physdev_map_pirq, and xl code pci_add_dm_done->xc_physdev_map_pirq, but in current codes, the gsi number is got from file /sys/bus/pci/devices/<sbdf>/irq, that is wrong, because irq is not equal with gsi, they are in different spaces, so pirq mapping fails. And in current linux codes, there is no method to get gsi for userspace. For above purpose, record gsi of pcistub devices when init pcistub and add a new syscall into privcmd to let userspace can get gsi when they have a need.

Pull more io_uring updates from Jens Axboe:
"Mostly just a set of fixes in here, or little changes that didn't get
included in the initial pull request. This contains:
- Move the SQPOLL napi polling outside the submission lock (Olivier)
- Rename of the "copy buffers" API that got added in the 6.12 merge
window. There's really no copying going on, it's just referencing
the buffers. After a bit of consideration, decided that it was
better to simply rename this to avoid potential confusion (me)
- Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
start + len tracking rather than having start / end in there, and
by removing the caching of folio_mask when we can just calculate it
from folio_shift when we need it (me)
- Fixes for the SQPOLL affinity checking (me, Felix)
- Fix for how cqring waiting checks for the presence of task_work.
Just check it directly rather than check for a specific
notification mechanism (me)
- Tweak to how request linking is represented in tracing (me)
- Fix a syzbot report that deliberately sets up a huge list of
overflow entries, and then hits rcu stalls when flushing this list.
Just check for the need to preempt, and drop/reacquire locks in the
loop. There's no state maintained over the loop itself, and each
entry is yanked from head-of-list (me)"

leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)

become accessible before restoring devices on that bus (Ilpo
Järvinen)

Pull bpf updates from Alexei Starovoitov:
- Introduce '__attribute__((bpf_fastcall))' for helpers and kfuncs with
corresponding support in LLVM.
It is similar to existing 'no_caller_saved_registers' attribute in
GCC/LLVM with a provision for backward compatibility. It allows
compilers generate more efficient BPF code assuming the verifier or
JITs will inline or partially inline a helper/kfunc with such
attribute. bpf_cast_to_kern_ctx, bpf_rdonly_cast,
bpf_get_smp_processor_id are the first set of such helpers.
- Harden and extend ELF build ID parsing logic.
When called from sleepable context the relevants parts of ELF file
will be read to find and fetch .note.gnu.build-id information. Also
harden the logic to avoid TOCTOU, overflow, out-of-bounds problems.
- Improvements and fixes for sched-ext:
- Allow passing BPF iterators as kfunc arguments
- Make the pointer returned from iter_next method trusted
- Fix x86 JIT convergence issue due to growing/shrinking conditional
jumps in variable length encoding
- BPF_LSM related:
- Introduce few VFS kfuncs and consolidate them in
fs/bpf_fs_kfuncs.c
- Enforce correct range of return values from certain LSM hooks
- Disallow attaching to other LSM hooks
- Prerequisite work for upcoming Qdisc in BPF:
- Allow kptrs in program provided structs
- Support for gen_epilogue in verifier_ops
- Important fixes:
- Fix uprobe multi pid filter check
- Fix bpf_strtol and bpf_strtoul helpers
- Track equal scalars history on per-instruction level
- Fix tailcall hierarchy on x86 and arm64
- Fix signed division overflow to prevent INT_MIN/-1 trap on x86
- Fix get kernel stack in BPF progs attached to tracepoint:syscall
- Selftests:
- Add uprobe bench/stress tool
- Generate file dependencies to drastically improve re-build time
- Match JIT-ed and BPF asm with __xlated/__jited keywords
- Convert older tests to test_progs framework
- Add support for RISC-V
- Few fixes when BPF programs are compiled with GCC-BPF backend
(support for GCC-BPF in BPF CI is ongoing in parallel)
- Add traffic monitor
- Enable cross compile and musl libc

ALong with the usual shower of singleton patches, notable patch series in
this pull request are:
"Align kvrealloc() with krealloc()" from Danilo Krummrich. Adds
consistency to the APIs and behaviour of these two core allocation
functions. This also simplifies/enables Rustification.
"Some cleanups for shmem" from Baolin Wang. No functional changes - mode
code reuse, better function naming, logic simplifications.
"mm: some small page fault cleanups" from Josef Bacik. No functional
changes - code cleanups only.
"Various memory tiering fixes" from Zi Yan. A small fix and a little
cleanup.
"mm/swap: remove boilerplate" from Yu Zhao. Code cleanups and
simplifications and .text shrinkage.
"Kernel stack usage histogram" from Pasha Tatashin and Shakeel Butt. This

In the v6.12 scheduler development cycle we had 63 commits from 18 contributors:
- Implement the SCHED_DEADLINE server infrastructure - Daniel Bristot de Oliveira's
last major contribution to the kernel:
"SCHED_DEADLINE servers can help fixing starvation issues of low priority
tasks (e.g., SCHED_OTHER) when higher priority tasks monopolize CPU
cycles. Today we have RT Throttling; DEADLINE servers should be able to
replace and improve that."
(Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes,
Youssef Esmat, Huang Shijie)
- Preparatory changes for sched_ext integration:
- Use set_next_task(.first) where required
- Fix up set_next_task() implementations
- Clean up DL server vs. core sched
- Split up put_prev_task_balance()
- Rework pick_next_task()
- Combine the last put_prev_task() and the first set_next_task()
- Rework dl_server
- Add put_prev_task(.next)
(Peter Zijlstra, with a fix by Tejun Heo)
- Complete the EEVDF transition and refine EEVDF scheduling:
- Implement delayed dequeue
- Allow shorter slices to wakeup-preempt
- Use sched_attr::sched_runtime to set request/slice suggestion
- Document the new feature flags
- Remove unused and duplicate-functionality fields
- Simplify & unify pick_next_task_fair()
- Misc debuggability enhancements
(Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann,
Valentin Schneider and Chuyi Zhou)
- Initialize the vruntime of a new task when it is first enqueued,
resulting in significant decrease in latency of newly woken tasks.
(Zhang Qiao)
- Introduce SM_IDLE and an idle re-entry fast-path in __schedule()
(K Prateek Nayak, Peter Zijlstra)
- Clean up and clarify the usage of Clean up usage of rt_task()
(Qais Yousef)
- Preempt SCHED_IDLE entities in strict cgroup hierarchies
(Tianchen Ding)
- Clarify the documentation of time units for deadline scheduler
parameters. (Christian Loehle)
- Remove the HZ_BW chicken-bit feature flag introduced a year ago,
the original change seems to be working fine.
(Phil Auld)
- Misc fixes and cleanups (Chen Yu, Dan Carpenter, Huang Shijie,
Peilin He, Qais Yousefm and Vincent Guittot)

exfat: Implement sops->shutdown and ioctl
We found that when writing a large file through buffer write, if the disk is inaccessible, exFAT does not return an error normally, which leads to the writing process not stopping properly. To easily reproduce this issue, you can follow the steps below: 1. format a device to exFAT and then mount (with a full disk erase) 2. dd if=/dev/zero of=/exfat_mount/test.img bs=1M count=8192 3. eject the device You may find that the dd process does not stop immediately and may continue for a long time. The root cause of this issue is that during buffer write process, exFAT does not need to access the disk to look up directory entries or the FAT table (whereas FAT would do) every time data is written. Instead, exFAT simply marks the buffer as dirty and returns, delegating the writeback operation to the writeback process. If the disk cannot be accessed at this time, the error will only be returned to the writeback process, and the original process will not receive the error, so it cannot be returned to the user side. When the disk cannot be accessed normally, an error should be returned to stop the writing process. Implement sops->shutdown and ioctl to shut down the file system when underlying block device is marked dead.

sound updates for 6.12-rc1
A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers

"A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek
RTL1320 SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers"

spi: Updates for v6.12
This is quite a quiet release for sPI. The one new core feature here is
support for configuring the state of the MOSI pin when the bus is idle,
there are some devices which are very fragile in this regard even when
the chip select signal is not asserted. Otherwise we have some new
driver support, a bunch of small fixes and some general cleanup work.
- Support for configuring the state of the MOSI pin when the the bus is
idle.
- Add the Elgin JG0309-01 in spidev.
- Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX,
NXP i.MX8ULP, and Rockchip RK3576 controllers.
I also accidentally pulled in an IIO DT bindings update due to a typo
when applying the MOSI idle state patches.

landlock: Add signal scoping
Currently, a sandbox process is not restricted to sending a signal (e.g. SIGKILL) to a process outside the sandbox environment. The ability to send a signal for a sandboxed process should be scoped the same way abstract UNIX sockets are scoped. Therefore, we extend the "scoped" field in a ruleset with LANDLOCK_SCOPE_SIGNAL to specify that a ruleset will deny sending any signal from within a sandbox process to its parent (i.e. any parent sandbox or non-sandboxed processes). This patch adds file_set_fowner and file_free_security hooks to set and release a pointer to the file owner's domain. This pointer, fown_domain in landlock_file_security will be used in file_send_sigiotask to check if the process can send a signal. The ruleset_with_unknown_scope test is updated to support LANDLOCK_SCOPE_SIGNAL. This depends on two new changes: - commit |

landlock: Add abstract UNIX socket scoping
Introduce a new "scoped" member to landlock_ruleset_attr that can specify LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET to restrict connection to abstract UNIX sockets from a process outside of the socket's domain. Two hooks are implemented to enforce these restrictions: unix_stream_connect and unix_may_send.

Those callbacks which haven't been converted were left as-is due to the general ugliness of the changes required to support the static call conversion; we can revisit those callbacks at a future date. - Add the Integrity Policy Enforcement (IPE) LSM This adds a new LSM, Integrity Policy Enforcement (IPE). There is plenty of documentation about IPE in this patches, so I'll refrain from going into too much detail here, but the basic motivation behind IPE is to provide a mechanism such that administrators can restrict execution to only those binaries which come from integrity protected storage, e.g. a dm-verity protected filesystem. You will notice that IPE requires additional LSM hooks in the initramfs, dm-verity, and fs-verity code, with the associated patches carrying ACK/review tags from the associated maintainers. We couldn't find an obvious maintainer for the initramfs code, but the IPE patchset has been widely posted over several years. Both Deven Bowers and Fan Wu have contributed to IPE's development over the past several years, with Fan Wu agreeing to serve as the IPE maintainer moving forward. Once IPE is accepted into your tree, I'll start working with Fan to ensure he has the necessary accounts, keys, etc. so that he can start submitting IPE pull requests to you directly during the next merge window. - Move the lifecycle management of the LSM blobs to the LSM framework Management of the LSM blobs (the LSM state buffers attached to various kernel structs, typically via a void pointer named "security" or similar) has been mixed, some blobs were allocated/managed by individual LSMs, others were managed by the LSM framework itself. Starting with this pull we move management of all the LSM blobs, minus the XFRM blob, into the framework itself, improving consistency across LSMs, and reducing the amount of duplicated code across LSMs. Due to some additional work required to migrate the XFRM blob, it has been left as a todo item for a later date; from a practical standpoint this omission should have little impact as only SELinux provides a XFRM LSM implementation. - Fix problems with the LSM's handling of F_SETOWN The LSM hook for the fcntl(F_SETOWN) operation had a couple of problems: it was racy with itself, and it was disconnected from the associated DAC related logic in such a way that the LSM state could be updated in cases where the DAC state would not. We fix both of these problems by moving the security_file_set_fowner() hook into the same section of code where the DAC attributes are updated. Not only does this resolve the DAC/LSM synchronization issue, but as that code block is protected by a lock, it also resolve the race condition. - Fix potential problems with the security_inode_free() LSM hook Due to use of RCU to protect inodes and the placement of the LSM hook associated with freeing the inode, there is a bit of a challenge when it comes to managing any LSM state associated with an inode. The VFS folks are not open to relocating the LSM hook so we have to get creative when it comes to releasing an inode's LSM state. Traditionally we have used a single LSM callback within the hook that is triggered when the inode is "marked for death", but not actually released due to RCU. Unfortunately, this causes problems for LSMs which want to take an action when the inode's associated LSM state is actually released; so we add an additional LSM callback, inode_free_security_rcu(), that is called when the inode's LSM state is released in the RCU free callback. - Refactor two LSM hooks to better fit the LSM return value patterns The vast majority of the LSM hooks follow the "return 0 on success, negative values on failure" pattern, however, there are a small handful that have unique return value behaviors which has caused confusion in the past and makes it difficult for the BPF verifier to properly vet BPF LSM programs. This includes patches to convert two of these"special" LSM hooks to the common 0/-ERRNO pattern. - Various cleanups and improvements A handful of patches to remove redundant code, better leverage the IS_ERR_OR_NULL() helper, add missing "static" markings, and do some minor style fixups. * tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (40 commits) security: Update file_set_fowner documentation fs: Fix file_set_fowner LSM hook inconsistencies lsm: Use IS_ERR_OR_NULL() helper function lsm: remove LSM_COUNT and LSM_CONFIG_COUNT ipe: Remove duplicated include in ipe.c lsm: replace indirect LSM hook calls with static calls lsm: count the LSMs enabled at compile time kernel: Add helper macros for loop unrolling init/main.c: Initialize early LSMs after arch code, static keys and calls.

Pull vfs mount updates from Christian Brauner:
"Recently, we added the ability to list mounts in other mount
namespaces and the ability to retrieve namespace file descriptors
without having to go through procfs by deriving them from pidfds.
This extends nsfs in two ways:
(1) Add the ability to retrieve information about a mount namespace
via NS_MNT_GET_INFO.
This will return the mount namespace id and the number of mounts
currently in the mount namespace. The number of mounts can be
used to size the buffer that needs to be used for listmount() and
is in general useful without having to actually iterate through
all the mounts.
The structure is extensible.
(2) Add the ability to iterate through all mount namespaces over
which the caller holds privilege returning the file descriptor
for the next or previous mount namespace.
To retrieve a mount namespace the caller must be privileged wrt
to it's owning user namespace. This means that PID 1 on the host
can list all mounts in all mount namespaces or that a container
can list all mounts of its nested containers.
Optionally pass a structure for NS_MNT_GET_INFO with
NS_MNT_GET_{PREV,NEXT} to retrieve information about the mount
namespace in one go.
(1) and (2) can be implemented for other namespace types easily.
Together with recent api additions this means one can iterate through
all mounts in all mount namespaces without ever touching procfs.

Pull misc vfs updates from Christian Brauner:
"This contains the usual pile of misc updates:
Features:
- Add F_CREATED_QUERY fcntl() that allows userspace to query whether
a file was actually created. Often userspace wants to know whether
an O_CREATE request did actually create a file without using
O_EXCL. The current logic is that to first attempts to open the
file without O_CREAT | O_EXCL and if ENOENT is returned userspace
tries again with both flags. If that succeeds all is well. If it
now reports EEXIST it retries.
That works fairly well but some corner cases make this more
involved. If this operates on a dangling symlink the first openat()
without O_CREAT | O_EXCL will return ENOENT but the second openat()
with O_CREAT | O_EXCL will fail with EEXIST.
The reason is that openat() without O_CREAT | O_EXCL follows the
symlink while O_CREAT | O_EXCL doesn't for security reasons. So
it's not something we can really change unless we add an explicit
opt-in via O_FOLLOW which seems really ugly.
All available workarounds are really nasty (fanotify, bpf lsm etc)
so add a simple fcntl().
- Try an opportunistic lookup for O_CREAT. Today, when opening a file
we'll typically do a fast lookup, but if O_CREAT is set, the kernel
always takes the exclusive inode lock. This was likely done with
the expectation that O_CREAT means that we always expect to do the
create, but that's often not the case. Many programs set O_CREAT
even in scenarios where the file already exists (see related
F_CREATED_QUERY patch motivation above).
The series contained in the pr rearranges the pathwalk-for-open
code to also attempt a fast_lookup in certain O_CREAT cases. If a
positive dentry is found, the inode_lock can be avoided altogether
and it can stay in rcuwalk mode for the last step_into.
- Expose the 64 bit mount id via name_to_handle_at()
Now that we provide a unique 64-bit mount ID interface in statx(2),
we can now provide a race-free way for name_to_handle_at(2) to
provide a file handle and corresponding mount without needing to
worry about racing with /proc/mountinfo parsing or having to open a
file just to do statx(2).
While this is not necessary if you are using AT_EMPTY_PATH and
don't care about an extra statx(2) call, users that pass full paths
into name_to_handle_at(2) need to know which mount the file handle
comes from (to make sure they don't try to open_by_handle_at a file
handle from a different filesystem) and switching to AT_EMPTY_PATH
would require allocating a file for every name_to_handle_at(2) call
- Add a per dentry expire timeout to autofs
There are two fairly well known automounter map formats, the autofs
format and the amd format (more or less System V and Berkley).
Some time ago Linux autofs added an amd map format parser that
implemented a fair amount of the amd functionality. This was done
within the autofs infrastructure and some functionality wasn't
implemented because it either didn't make sense or required extra
kernel changes. The idea was to restrict changes to be within the
existing autofs functionality as much as possible and leave changes
with a wider scope to be considered later.
One of these changes is implementing the amd options:
1) "unmount", expire this mount according to a timeout (same as
the current autofs default).
2) "nounmount", don't expire this mount (same as setting the
autofs timeout to 0 except only for this specific mount) .
3) "utimeout=<seconds>", expire this mount using the specified
timeout (again same as setting the autofs timeout but only for
this mount)
To implement these options per-dentry expire timeouts need to be
implemented for autofs indirect mounts. This is because all map
keys (mounts) for autofs indirect mounts use an expire timeout
stored in the autofs mount super block info. structure and all
indirect mounts use the same expire timeout.
Fixes:
- Fix missing fput for FSCONFIG_SET_FD in autofs
- Use param->file for FSCONFIG_SET_FD in coda
- Delete the 'fs/netfs' proc subtreee when netfs module exits
- Make sure that struct uid_gid_map fits into a single cacheline
- Don't flush in-flight wb switches for superblocks without cgroup
writeback
- Correcting the idmapping mount example in the idmapping
documentation
- Fix a race between evice_inodes() and find_inode() and iput()
- Refine the show_inode_state() macro definition in writeback code
- Prevent dump_mapping() from accessing invalid dentry.d_name.name
- Show actual source for debugfs in /proc/mounts
- Annotate data-race of busy_poll_usecs in eventpoll
- Don't WARN for racy path_noexec check in exec code
- Handle OOM on mnt_warn_timestamp_expiry()
- Fix some spelling in the iomap design documentation
- Fix typo in procfs comment
- Fix typo in fs/namespace.c comment
Cleanups:
- Add the VFS git tree to the MAINTAINERS file
- Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode
bit in struct file bringing us to 5 free f_mode bits
- Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify
the wait mechanism
- Remove the unused path_put_init() helper
- Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi
specific
- Replace the unsigned long i_state member with a u32 i_state member
in struct inode freeing up 4 bytes in struct inode. Instead of
using the bit based wait apis we're now using the var event apis
and using the individual bytes of the i_state member to wait on
state changes
- Explain how per-syscall AT_* flags should be allocated
- Use in_group_or_capable() helper to simplify the posix acl mode
update code
- Switch to LIST_HEAD() in fsync_buffers_list() to simplify the code
- Removed comment about d_rcu_to_refcount() as that function doesn't
exist anymore
- Add kernel documentation for lookup_fast()
- Don't re-zero evenpoll fields
- Remove outdated comment after close_fd()
- Fix imprecise wording in comment about the pipe filesystem
- Drop GFP_NOFAIL mode from alloc_page_buffers
- Missing blank line warnings and struct declaration improved in
file_table
- Annotate struct poll_list with __counted_by()
- Remove the unused read parameter in percpu-rwsem
- Remove linux/prefetch.h include from direct-io code
- Use kmemdup_array instead of kmemdup for multiple allocation in
mnt_idmapping code
- Remove unused mnt_cursor_del() declaration
Performance tweaks:
- Dodge smp_mb in break_lease and break_deleg in the common case
- Only read fops once in fops_{get,put}()
- Use RCU in ilookup()
- Elide smp_mb in iversion handling in the common case
- Drop one lock trip in evict()"

io_uring: rename "copy buffers" to "clone buffers"
A recent commit added support for copying registered buffers from one
ring to another. But that term is a bit confusing, as no copying of
buffer data is done here. What is being done is simply cloning the
buffer registrations from one ring to another.
Rename it while we still can, so that it's more descriptive. No
functional changes in this patch.

net: fib_rules: Add DSCP selector attribute
The FIB rule TOS selector is implemented differently between IPv4 and IPv6. In IPv4 it is used to match on the three "Type of Services" bits specified in RFC 791, while in IPv6 is it is used to match on the six DSCP bits specified in RFC 2474. Add a new FIB rule attribute to allow matching on DSCP. The attribute will be used to implement a 'dscp' selector in ip-rule with a consistent behavior between IPv4 and IPv6. For now, set the type of the attribute to 'NLA_REJECT' so that user space will not be able to configure it. This restriction will be lifted once both IPv4 and IPv6 support the new attribute.

io_uring: add IORING_REGISTER_COPY_BUFFERS method
Buffers can get registered with io_uring, which allows to skip the repeated pin_pages, unpin/unref pages for each O_DIRECT operation. This reduces the overhead of O_DIRECT IO. However, registrering buffers can take some time. Normally this isn't an issue as it's done at initialization time (and hence less critical), but for cases where rings can be created and destroyed as part of an IO thread pool, registering the same buffers for multiple rings become a more time sensitive proposition. As an example, let's say an application has an IO memory pool of 500G. Initial registration takes: Got 500 huge pages (each 1024MB) Registered 500 pages in 409 msec or about 0.4 seconds. If we go higher to 900 1GB huge pages being registered: Registered 900 pages in 738 msec which is, as expected, a fully linear scaling. Rather than have each ring pin/map/register the same buffer pool, provide an io_uring_register(2) opcode to simply duplicate the buffers that are registered with another ring. Adding the same 900GB of registered buffers to the target ring can then be accomplished in: Copied 900 pages in 17 usec While timing differs a bit, this provides around a 25,000-40,000x speedup for this use case.

net: ethernet: oa_tc6: implement internal PHY initialization
Internal PHY is initialized as per the PHY register capability supported by the MAC-PHY. Direct PHY Register Access Capability indicates if PHY registers are directly accessible within the SPI register memory space. Indirect PHY Register Access Capability indicates if PHY registers are indirectly accessible through the MDIO/MDC registers MDIOACCn defined in OPEN Alliance specification. Currently the direct register access is only supported.

tcp: RX path for devmem TCP
In tcp_recvmsg_locked(), detect if the skb being received by the user is a devmem skb. In this case - if the user provided the MSG_SOCK_DEVMEM flag - pass it to tcp_recvmsg_devmem() for custom handling. tcp_recvmsg_devmem() copies any data in the skb header to the linear buffer, and returns a cmsg to the user indicating the number of bytes returned in the linear buffer. tcp_recvmsg_devmem() then loops over the unaccessible devmem skb frags, and returns to the user a cmsg_devmem indicating the location of the data in the dmabuf device memory. cmsg_devmem contains this information: 1. the offset into the dmabuf where the payload starts. 'frag_offset'. 2. the size of the frag. 'frag_size'. 3. an opaque token 'frag_token' to return to the kernel when the buffer is to be released. The pages awaiting freeing are stored in the newly added sk->sk_user_frags, and each page passed to userspace is get_page()'d. This reference is dropped once the userspace indicates that it is done reading this page. All pages are released when the socket is destroyed.

block: implement async io_uring discard cmd
io_uring allows implementing custom file specific asynchronous operations via the fops->uring_cmd callback, a.k.a. IORING_OP_URING_CMD requests or just io_uring commands. Use it to add support for async discards. Normally, it first tries to queue up bios in a non-blocking context, and if that fails, we'd retry from a blocking context by returning -EAGAIN to the core io_uring. We always get the result from bios asynchronously by setting a custom bi_end_io callback, at which point we drag the request into the task context to either reissue or complete it and post a completion to the user. Unlike ioctl(BLKDISCARD) with stronger guarantees against races, we only do a best effort attempt to invalidate page cache, and it can race with any writes and reads and leave page cache stale. It's the same kind of races we allow to direct writes. Also, apart from cases where discarding is not allowed at all, e.g. discards are not supported or the file/device is read only, the user should assume that the sector range on disk is not valid anymore, even when an error was returned to the user.

PCI: Rename CRS Completion Status to RRS
PCIe r6.0 changed the abbreviation for "Configuration Request Retry Status" Completion Status from "CRS" to "RRS" and uses the terminology of "Configuration RRS Software Visibility" instead of "CRS Software Visibility". Align the Linux usage with the r6.0 spec language. No functional change intended. It's confusing to make this change, but I think "RRS" *is* a better abbreviation because it was easy to interpret "CRS" as "Completion Retry Status", which really didn't make any sense.

net-timestamp: introduce SOF_TIMESTAMPING_OPT_RX_FILTER flag
introduce a new flag SOF_TIMESTAMPING_OPT_RX_FILTER in the receive path. User can set it with SOF_TIMESTAMPING_SOFTWARE to filter out rx software timestamp report, especially after a process turns on netstamp_needed_key which can time stamp every incoming skb. Previously, we found out if an application starts first which turns on netstamp_needed_key, then another one only passing SOF_TIMESTAMPING_SOFTWARE could also get rx timestamp. Now we handle this case by introducing this new flag without breaking users. Quoting Willem to explain why we need the flag: "why a process would want to request software timestamp reporting, but not receive software timestamp generation. The only use I see is when the application does request SOF_TIMESTAMPING_SOFTWARE | SOF_TIMESTAMPING_TX_SOFTWARE." Similarly, this new flag could also be used for hardware case where we can set it with SOF_TIMESTAMPING_RAW_HARDWARE, then we won't receive hardware receive timestamp. Another thing about errqueue in this patch I have a few words to say: In this case, we need to handle the egress path carefully, or else reporting the tx timestamp will fail. Egress path and ingress path will finally call sock_recv_timestamp(). We have to distinguish them. Errqueue is a good indicator to reflect the flow direction.

ptp/ioctl: support MONOTONIC{,_RAW} timestamps for PTP_SYS_OFFSET_EXTENDED
The ability to read the PHC (Physical Hardware Clock) alongside multiple system clocks is currently dependent on the specific hardware architecture. This limitation restricts the use of PTP_SYS_OFFSET_PRECISE to certain hardware configurations. The generic soultion which would work across all architectures is to read the PHC along with the latency to perform PHC-read as offered by PTP_SYS_OFFSET_EXTENDED which provides pre and post timestamps. However, these timestamps are currently limited to the CLOCK_REALTIME timebase. Since CLOCK_REALTIME is affected by NTP (or similar time synchronization services), it can experience significant jumps forward or backward. This hinders the precise latency measurements that PTP_SYS_OFFSET_EXTENDED is designed to provide. This problem could be addressed by supporting MONOTONIC_RAW timestamps within PTP_SYS_OFFSET_EXTENDED. Unlike CLOCK_REALTIME or CLOCK_MONOTONIC, the MONOTONIC_RAW timebase is unaffected by NTP adjustments. This enhancement can be implemented by utilizing one of the three reserved words within the PTP_SYS_OFFSET_EXTENDED struct to pass the clock-id for timestamps. The current behavior aligns with clock-id for CLOCK_REALTIME timebase (value of 0), ensuring backward compatibility of the UAPI.

Patch #10 disallows element expiration larger than timeout. Patch #11 removes unnecessary READ_ONCE annotation while mutex is held. Patch #12 adds missing READ_ONCE/WRITE_ONCE annotation in dynset. Patch #13 annotates data-races around element expiration. Patch #14 allocates timeout and expiration in one single set element extension, they are tighly couple, no reason to keep them separated anymore. Patch #15 updates nftables to interpret zero timeout element as never times out. Note that it is already possible to declare sets with elements that never time out but this generalizes to all kind of set with timeouts. Patch #16 supports for element timeout and expiration updates. * tag 'nf-next-24-09-06' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next: netfilter: nf_tables: set element timeout update support netfilter: nf_tables: zero timeout means element never times out netfilter: nf_tables: consolidate timeout extension for elements netfilter: nf_tables: annotate data-races around element expiration netfilter: nft_dynset: annotate data-races around set timeout netfilter: nf_tables: remove annotation to access set timeout while holding lock netfilter: nf_tables: reject expiration higher than timeout netfilter: nf_tables: reject element expiration with no timeout netfilter: nf_tables: elements with timeout below CONFIG_HZ never expire netfilter: nf_tables: Add missing Kernel doc netfilter: nf_tables: Correct spelling in nf_tables.h netfilter: nf_tables: drop unused 3rd argument from validate callback ops netfilter: conntrack: Convert to use ERR_CAST() netfilter: Use kmemdup_array instead of kmemdup for multiple allocation netfilter: nft_counter: Use u64_stats_t for statistic. netfilter: ctnetlink: support CTA_FILTER for flush ==================== Link: https://patch.msgid.link/20240905232920.5481-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

drm/amdkfd: Document and define SVM events message macro
Document how to use SMI system management interface to enable and receive SVM events. Document SVM event triggers. Define SVM events message string format macro that could be used by user mode for sscanf to parse the event. Add it to uAPI header file to make it obvious that is changing uAPI in future. No functional changes. Signed-off-by: Philip Yang <Philip.Yang@amd.com> Reviewed-by: James Zhu <James.Zhu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |

sound fixes for 6.11-rc7
Hopefully the last PR for 6.11, at least for this level of amount. In addition to the usual HD-audio quirks, there are more changes in ASoC, but all look small and device-specific fixes, and nothing stands out. The only slightly big change is sunxi I2S fix, which looks quite safe to apply, too. -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmbaxkIOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE/xDQ/9ESOhr5vmViDZ/LOXrmA36Mc7byvDE0ku9TsN bEBRSo2J5GJX3ty9ST6Pwm4jRlPAXRrqqWNhP2b+nQTTdzRWFQC58m79BSGmGWRA qyuFPakn1tiCdl5rvHS7hpYfzMkc8amVILhhJyhbv7Zg0UPriczPL3JI/W2GAJRs vMuHAD2ulSTVcJdYGgvny5JGWVQ649mQw7rfp+h3G9kXRLyOXKamGLU2e68TEZLq owUifBS1rC7+jXUn6dZ5MU86BLMQFCCDCOUjEEklH08Y+1DzqlS+JE80NcJlUBo8 xNHoY1xFqDb0DAPb3w7P5IfCMBkb1I2uyHyMQg+SJeN05qXiSAKIsZhr5/NeivFq clB6R9l3tmN66lQEqr1ZxBEx6Sgr40Deh2qFOjyq7xsm+PRU4oPdels4+awRTWPy 8fr/L2wWtYGGILM7iDkasgVeYQZGFJ7AG0gC0AyUoKtEcZZsQUiwfAWT85K4GLP9 mmUMwqZH3nKtOxXgphSGbxOnep9cWNT7IJ/NXZ1iNGlByLXVDk5fIlOUK8983gCx duuFA1CpR3RwayGOo2UIwT62+qOTtfwGGKkHAPWjbBWa/daNxI8UEaHH/XEH3qyy iK8xFIkKimi95hjAA8FmVN6aGkeu3OCnQvdzbP3f3k0Tj1xe3t42xhPmQVl9yrpu lwIdl20= =npz1 -----END PGP SIGNATURE----- Merge tag 'sound-6.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "Hopefully the last PR for 6.11, at least for this level of amount.
