[ Upstream commit 22bbc1dcd0d6785fb390c41f0dd5b5e218d23bdd ]
If a userspace application just include <linux/vm_sockets.h> will fail
to build with the following errors:
/usr/include/linux/vm_sockets.h:182:39: error: invalid application of ‘sizeof’ to incomplete type ‘struct sockaddr’
182 | unsigned char svm_zero[sizeof(struct sockaddr) -
| ^~~~~~
/usr/include/linux/vm_sockets.h:183:39: error: ‘sa_family_t’ undeclared here (not in a function)
183 | sizeof(sa_family_t) -
|
Include <sys/socket.h> for userspace (guarded by ifndef __KERNEL__)
where `struct sockaddr` and `sa_family_t` are defined.
We already do something similar in <linux/mptcp.h> and <linux/if.h>.

[ Upstream commit 94b2a2c0e7cba3f163609dbd94120ee533ad2a07 ]
Copy engine was deprecated by the FW and is no longer supported.
Compute engine includes all copy engine functionality and should be used
instead.
This change does not affect user space as the copy engine was never
used outside of a couple of tests.

commit ead7f9b8de65632ef8060b84b0c55049a33cfea1 upstream.
In Cilium, we use bpf_csum_diff + bpf_l4_csum_replace to, among other
things, update the L4 checksum after reverse SNATing IPv6 packets. That
use case is however not currently supported and leads to invalid
skb->csum values in some cases. This patch adds support for IPv6 address
changes in bpf_l4_csum_update via a new flag.
When calling bpf_l4_csum_replace in Cilium, it ends up calling
inet_proto_csum_replace_by_diff:
1: void inet_proto_csum_replace_by_diff(__sum16 *sum, struct sk_buff *skb,
2: __wsum diff, bool pseudohdr)
3: {
4: if (skb->ip_summed != CHECKSUM_PARTIAL) {
5: csum_replace_by_diff(sum, diff);
6: if (skb->ip_summed == CHECKSUM_COMPLETE && pseudohdr)
7: skb->csum = ~csum_sub(diff, skb->csum);
8: } else if (pseudohdr) {
9: *sum = ~csum_fold(csum_add(diff, csum_unfold(*sum)));
10: }
11: }
The bug happens when we're in the CHECKSUM_COMPLETE state. We've just
updated one of the IPv6 addresses. The helper now updates the L4 header
checksum on line 5. Next, it updates skb->csum on line 7. It shouldn't.
For an IPv6 packet, the updates of the IPv6 address and of the L4
checksum will cancel each other. The checksums are set such that
computing a checksum over the packet including its checksum will result
in a sum of 0. So the same is true here when we update the L4 checksum
on line 5. We'll update it as to cancel the previous IPv6 address
update. Hence skb->csum should remain untouched in this case.
The same bug doesn't affect IPv4 packets because, in that case, three
fields are updated: the IPv4 address, the IP checksum, and the L4
checksum. The change to the IPv4 address and one of the checksums still
cancel each other in skb->csum, but we're left with one checksum update
and should therefore update skb->csum accordingly. That's exactly what
inet_proto_csum_replace_by_diff does.
This special case for IPv6 L4 checksums is also described atop
inet_proto_csum_replace16, the function we should be using in this case.
This patch introduces a new bpf_l4_csum_replace flag, BPF_F_IPV6,
to indicate that we're updating the L4 checksum of an IPv6 packet. When
the flag is set, inet_proto_csum_replace_by_diff will skip the
skb->csum update.

[ Upstream commit 4b82b181a26cff8bf7adc3a85a88d121d92edeaf ]
Currently for bpf progs in a cgroup hierarchy, the effective prog array
is computed from bottom cgroup to upper cgroups (post-ordering). For
example, the following cgroup hierarchy
root cgroup: p1, p2
subcgroup: p3, p4
have BPF_F_ALLOW_MULTI for both cgroup levels.
The effective cgroup array ordering looks like
p3 p4 p1 p2
and at run time, progs will execute based on that order.
But in some cases, it is desirable to have root prog executes earlier than
children progs (pre-ordering). For example,
- prog p1 intends to collect original pkt dest addresses.
- prog p3 will modify original pkt dest addresses to a proxy address for
security reason.
The end result is that prog p1 gets proxy address which is not what it
wants. Putting p1 to every child cgroup is not desirable either as it
will duplicate itself in many child cgroups. And this is exactly a use case
we are encountering in Meta.
To fix this issue, let us introduce a flag BPF_F_PREORDER. If the flag
is specified at attachment time, the prog has higher priority and the
ordering with that flag will be from top to bottom (pre-ordering).
For example, in the above example,
root cgroup: p1, p2
subcgroup: p3, p4
Let us say p2 and p4 are marked with BPF_F_PREORDER. The final
effective array ordering will be
p2 p4 p3 p1

[ Upstream commit 803f97298e7de9242eb677a1351dcafbbcc9117e ]
PASID usage requires PASID support in both device and IOMMU. Since the
iommu drivers always enable the PASID capability for the device if it
is supported, this extends the IOMMU_GET_HW_INFO to report the PASID
capability to userspace. Also, enhances the selftest accordingly.

[ Upstream commit 6c2b75404d33caa46a582f2791a70f92232adb71 ]
Fix the frequency returned to the user space by
the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL.
The kernel driver returned CPU frequency for MTL and bare
PLL frequency for LNL - this was inconsistent and incorrect
for both platforms. With this fix the driver returns maximum
frequency of the NPU data processing unit (DPU) for all HW
generations. This is what user space always expected.
Also do not set CPU frequency in boot params - the firmware
does not use frequency passed from the driver, it was only
used by the early pre-production firmware.
With that we can remove CPU frequency calculation code.
Show NPU frequency in FREQ_CHANGE interrupt when frequency
tracking is enabled.

commit 15383a0d63dbcd63dc7e8d9ec1bf3a0f7ebf64ac upstream.
Some fixes may require user space to check if they are applied on the
running kernel before using a specific feature. For instance, this
applies when a restriction was previously too restrictive and is now
getting relaxed (e.g. for compatibility reasons). However, non-visible
changes for legitimate use (e.g. security fixes) do not require an
erratum.
Because fixes are backported down to a specific Landlock ABI, we need a
way to avoid cherry-pick conflicts. The solution is to only update a
file related to the lower ABI impacted by this issue. All the ABI files
are then used to create a bitmask of fixes.
The new errata interface is similar to the one used to get the supported
Landlock ABI version, but it returns a bitmask instead because the order
of fixes may not match the order of versions, and not all fixes may
apply to all versions.
The actual errata will come with dedicated commits. The description is
not actually used in the code but serves as documentation.
Create the landlock_abi_version symbol and use its value to check errata
consistency.
Update test_base's create_ruleset_checks_ordering tests and add errata
tests.
This commit is backportable down to the first version of Landlock.

[ Upstream commit 18d92bb57c39504d9da11c6ef604f58eb1d5a117 ]
Hardware traces, such as instruction traces, can produce a vast amount of
trace data, so being able to reduce tracing to more specific circumstances
can be useful.
The ability to pause or resume tracing when another event happens, can do
that.
Add ability for an event to "pause" or "resume" AUX area tracing.
Add aux_pause bit to perf_event_attr to indicate that, if the event
happens, the associated AUX area tracing should be paused. Ditto
aux_resume. Do not allow aux_pause and aux_resume to be set together.
Add aux_start_paused bit to perf_event_attr to indicate to an AUX area
event that it should start in a "paused" state.
Add aux_paused to struct hw_perf_event for AUX area events to keep track of
the "paused" state. aux_paused is initialized to aux_start_paused.
Add PERF_EF_PAUSE and PERF_EF_RESUME modes for ->stop() and ->start()
callbacks. Call as needed, during __perf_event_output(). Add
aux_in_pause_resume to struct perf_buffer to prevent races with the NMI
handler. Pause/resume in NMI context will miss out if it coincides with
another pause/resume.
To use aux_pause or aux_resume, an event must be in a group with the AUX
area event as the group leader.
Example (requires Intel PT and tools patches also):
$ perf record --kcore -e intel_pt/aux-action=start-paused/k,syscalls:sys_enter_newuname/aux-action=resume/,syscalls:sys_exit_newuname/aux-action=pause/ uname

commit 2255b40cacc2e5ef1b127770fc1808c60de4a2fc upstream.
Vulkan can't support DCC and Z/S compression on GFX12 without
WRITE_COMPRESS_DISABLE in this commit or a completely different DCC
interface.
AMDGPU_TILING_GFX12_SCANOUT is added because it's already used by userspace.

commit 127186cfb184eaccdfe948e6da66940cfa03efc5 upstream.
THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated
CONFIG_MD_LINEAR") because it has been marked as deprecated for a long
time.
However, md-linear is used widely for underlying disks with different size,
sadly we didn't know this until now, and it's true useful to create
partitions and assemble multiple raid and then append one to the other.
People have to use dm-linear in this case now, however, they will prefer
to minimize the number of involved modules.

[ Upstream commit 1ddf9916ac09313128e40d6581cef889c0b4ce84 ]
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.

[ Upstream commit 724c6ce38bbaeb4b3f109b0e066d6c0ecd15446c ]
For the most part of the C++ history, it couldn't have type
declarations inside anonymous unions for different reasons. At the
same time, __struct_group() relies on the latters, so when the @TAG
argument is not empty, C++ code doesn't want to build (even under
`extern "C"`):
../linux/include/uapi/linux/pkt_cls.h:25:24: error:
'struct tc_u32_sel::<unnamed union>::tc_u32_sel_hdr,' invalid;
an anonymous union may only have public non-static data members
[-fpermissive]
The safest way to fix this without trying to switch standards (which
is impossible in UAPI anyway) etc., is to disable tag declaration
for that language. This won't break anything since for now it's not
buildable at all.
Use a separate definition for __struct_group() when __cplusplus is
defined to mitigate the error, including the version from tools/.

[ Upstream commit 522249f05c5551aec9ec0ba9b6438f1ec19c138d ]
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.

[ Upstream commit 9ab440a9d0426cf7842240891cc457155db1a97e ]
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.

commit 83134ef4609388f6b9ca31a384f531155196c2a7 upstream.
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.

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

Pull bitmap updates from Yury Norov:
- switch all bitmamp APIs from inline to __always_inline (Brian Norris)
The __always_inline series improves on code generation, and now with
the latest compiler versions is required to avoid compilation
warnings. It spent enough in my backlog, and I'm thankful to Brian
Norris for taking over and moving it forward.
- introduce GENMASK_U128() macro (Anshuman Khandual)
GENMASK_U128() is a prerequisite needed for arm64 development

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)"

retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)
- Rename CRS Completion Status to RRS ('Request Retry Status') to
match PCIe r6.0 spec usage (Bjorn Helgaas)
- Clear LBMS bit after a manual link retrain so we don't try to
retrain a link when there's no downstream device anymore (Maciej W.
Rozycki)
- Revert to the original link speed after retraining fails instead of
leaving it restricted to 2.5GT/s, so a future device has a chance
to use higher speeds (Maciej W. Rozycki)
- Wait for each level of downstream bus, not just the first, to
become accessible before restoring devices on that bus (Ilpo
Järvinen)

specific CPU core (Marek Vasut)
- Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,

- Use the 'bridge' reset method if described in the DT (Jim Quinlan)
- Use the 'swinit' reset method if described in the DT (Jim Quinlan)

- Rename SoC 'type' to 'soc_base' express the fact that SoCs come in
families of multiple similar devices (Jim Quinlan)

statements (Frank Li)
- Manage core reset by using SoC-specific callbacks instead of switch
statements (Frank Li)
- Expand comments for erratum ERR010728 workaround (Frank Li)

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext support from Tejun Heo:
"This implements a new scheduler class called ‘ext_sched_class’, or
sched_ext, which allows scheduling policies to be implemented as BPF
programs.
The goals of this are:
- Ease of experimentation and exploration: Enabling rapid iteration
of new scheduling policies.
- Customization: Building application-specific schedulers which
implement policies that are not applicable to general-purpose
schedulers.
- Rapid scheduler deployments: Non-disruptive swap outs of scheduling
policies in production environments"
See individual commits for more documentation, but also the cover letter
for the latest series:

git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
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
