Pull cgroup updates from Tejun Heo:
- Yafang Shao added task_get_cgroup1() helper to enable a similar BPF
helper so that BPF progs can be more useful on cgroup1 hierarchies.
While cgroup1 is mostly in maintenance mode, this addition is very
small while having an outsized usefulness for users who are still on
cgroup1. Yafang also optimized root cgroup list access by making it
RCU protected in the process.
- Waiman Long optimized rstat operation leading to substantially lower
and more consistent lock hold time while flushing the hierarchical
statistics. As the lock can be acquired briefly in various hot paths,
this reduction has cascading benefits.
- Waiman also improved the quality of isolation for cpuset's isolated
partitions. CPUs which are allocated to isolated partitions are now
excluded from running unbound work items and cpu_is_isolated() test
which is used by vmstat and memcg to reduce interference now includes
cpuset isolated CPUs. While it isn't there yet, the hope is
eventually reaching parity with the isolation level provided by the
`isolcpus` boot param but in a dynamic manner.

Pull scheduler updates from Ingo Molnar:
"Energy scheduling:
- Consolidate how the max compute capacity is used in the scheduler
and how we calculate the frequency for a level of utilization.
- Rework interface between the scheduler and the schedutil governor
- Simplify the util_est logic
Deadline scheduler:
- Work more towards reducing SCHED_DEADLINE starvation of low
priority tasks (e.g., SCHED_OTHER) tasks when higher priority tasks
monopolize CPU cycles, via the introduction of 'deadline servers'
(nested/2-level scheduling).
"Fair servers" to make use of this facility are not introduced yet.
EEVDF:
- Introduce O(1) fastpath for EEVDF task selection
NUMA balancing:
- Tune the NUMA-balancing vma scanning logic some more, to better
distribute the probability of a particular vma getting scanned.
Plus misc fixes, cleanups and updates"

Commit d8b0f5465012 ("wire up syscalls for statmount/listmount") added
two new system calls to arch/arm64/include/asm/unistd32.h but forgot to
update the __NR_compat_syscalls number, thus causing the following build
failures:
arch/arm64/include/asm/unistd32.h:922:24: error: array index in initializer exceeds array bounds
922 | #define __NR_statmount 457
| ^~~
arch/arm64/kernel/sys32.c:130:34: note: in definition of macro '__SYSCALL'
130 | #define __SYSCALL(nr, sym) [nr] = __arm64_##sym,
| ^~
Bump up the number by two to accomodate for the new system calls added.

Pull vfs cachefiles updates from Christian Brauner:
"This contains improvements for on-demand cachefiles.
If the daemon crashes and the on-demand cachefiles fd is unexpectedly
closed in-flight requests and subsequent read operations associated
with the fd will fail with EIO. This causes issues in various
scenarios as this failure is currently unrecoverable.
The work contained in this pull request introduces a failover mode and
enables the daemon to recover in-flight requested-related objects. A
restarted daemon will be able to process requests as usual.
This requires that in-flight requests are stored during daemon crash
or while the daemon is offline. In addition, a handle to
/dev/cachefiles needs to be stored.
This can be done by e.g., systemd's fdstore (cf. [1]) which enables
the restarted daemon to recover state.
Three new states are introduced in this patchset:
(1) CLOSE
Object is closed by the daemon.
(2) OPEN
Object is open and ready for processing. IOW, the open request
has been handled successfully.
(3) REOPENING
Object has been previously closed and is now reopened due to a
read request.
A restarted daemon can recover the /dev/cachefiles fd from systemd's
fdstore and writes "restore" to the device. This causes the object
state to be reset from CLOSE to REOPENING and reinitializes the
object.
The daemon may now handle the open request. Any in-flight operations
are restored and handled avoiding interruptions for users"

Pull vfs rw updates from Christian Brauner:
"This contains updates from Amir for read-write backing file helpers
for stacking filesystems such as overlayfs:
- Fanotify is currently in the process of introducing pre content
events. Roughly, a new permission event will be added indicating
that it is safe to write to the file being accessed. These events
are used by hierarchical storage managers to e.g., fill the content
of files on first access.
During that work we noticed that our current permission checking is
inconsistent in rw_verify_area() and remap_verify_area().
Especially in the splice code permission checking is done multiple
times. For example, one time for the whole range and then again for
partial ranges inside the iterator.
In addition, we mostly do permission checking before we call
file_start_write() except for a few places where we call it after.
For pre-content events we need such permission checking to be done
before file_start_write(). So this is a nice reason to clean this
all up.
After this series, all permission checking is done before
file_start_write().
As part of this cleanup we also massaged the splice code a bit. We
got rid of a few helpers because we are alredy drowning in special
read-write helpers. We also cleaned up the return types for splice
helpers.
- Introduce generic read-write helpers for backing files. This lifts
some overlayfs code to common code so it can be used by the FUSE
passthrough work coming in over the next cycles. Make Amir and
Miklos the maintainers for this new subsystem of the vfs"

Pull vfs mount updates from Christian Brauner:
"This contains the work to retrieve detailed information about mounts
via two new system calls. This is hopefully the beginning of the end
of the saga that started with fsinfo() years ago.
The LWN articles in [1] and [2] can serve as a summary so we can avoid
rehashing everything here.
At LSFMM in May 2022 we got into a room and agreed on what we want to
do about fsinfo(). Basically, split it into pieces. This is the first
part of that agreement. Specifically, it is concerned with retrieving
information about mounts. So this only concerns the mount information
retrieval, not the mount table change notification, or the extended
filesystem specific mount option work. That is separate work.
Currently mounts have a 32bit id. Mount ids are already in heavy use
by libmount and other low-level userspace but they can't be relied
upon because they're recycled very quickly. We agreed that mounts
should carry a unique 64bit id by which they can be referenced
directly. This is now implemented as part of this work.
The new 64bit mount id is exposed in statx() through the new
STATX_MNT_ID_UNIQUE flag. If the flag isn't raised the old mount id is
returned. If it is raised and the kernel supports the new 64bit mount
id the flag is raised in the result mask and the new 64bit mount id is
returned. New and old mount ids do not overlap so they cannot be
conflated.
Two new system calls are introduced that operate on the 64bit mount
id: statmount() and listmount(). A summary of the api and usage can be
found on LWN as well (cf. [3]) but of course, I'll provide a summary
here as well.
Both system calls rely on struct mnt_id_req. Which is the request
struct used to pass the 64bit mount id identifying the mount to
operate on. It is extensible to allow for the addition of new
parameters and for future use in other apis that make use of mount
ids.
statmount() mimicks the semantics of statx() and exposes a set flags
that userspace may raise in mnt_id_req to request specific information
to be retrieved. A statmount() call returns a struct statmount filled
in with information about the requested mount. Supported requests are
indicated by raising the request flag passed in struct mnt_id_req in
the @mask argument in struct statmount.
Currently we do support:
- STATMOUNT_SB_BASIC:
Basic filesystem info
- STATMOUNT_MNT_BASIC
Mount information (mount id, parent mount id, mount attributes etc)
- STATMOUNT_PROPAGATE_FROM
Propagation from what mount in current namespace
- STATMOUNT_MNT_ROOT
Path of the root of the mount (e.g., mount --bind /bla /mnt returns /bla)
- STATMOUNT_MNT_POINT
Path of the mount point (e.g., mount --bind /bla /mnt returns /mnt)
- STATMOUNT_FS_TYPE
Name of the filesystem type as the magic number isn't enough due to submounts
The string options STATMOUNT_MNT_{ROOT,POINT} and STATMOUNT_FS_TYPE
are appended to the end of the struct. Userspace can use the offsets
in @fs_type, @mnt_root, and @mnt_point to reference those strings
easily.
The struct statmount reserves quite a bit of space currently for
future extensibility. This isn't really a problem and if this bothers
us we can just send a follow-up pull request during this cycle.
listmount() is given a 64bit mount id via mnt_id_req just as
statmount(). It takes a buffer and a size to return an array of the
64bit ids of the child mounts of the requested mount. Userspace can
thus choose to either retrieve child mounts for a mount in batches or
iterate through the child mounts. For most use-cases it will be
sufficient to just leave space for a few child mounts. But for big
mount tables having an iterator is really helpful. Iterating through a
mount table works by setting @param in mnt_id_req to the mount id of
the last child mount retrieved in the previous listmount() call"

Pull vfs super updates from Christian Brauner:
"This contains the super work for this cycle including the long-awaited
series by Jan to make it possible to prevent writing to mounted block
devices:
- Writing to mounted devices is dangerous and can lead to filesystem
corruption as well as crashes. Furthermore syzbot comes with more
and more involved examples how to corrupt block device under a
mounted filesystem leading to kernel crashes and reports we can do
nothing about. Add tracking of writers to each block device and a
kernel cmdline argument which controls whether other writeable
opens to block devices open with BLK_OPEN_RESTRICT_WRITES flag are
allowed.
Note that this effectively only prevents modification of the
particular block device's page cache by other writers. The actual
device content can still be modified by other means - e.g. by
issuing direct scsi commands, by doing writes through devices lower
in the storage stack (e.g. in case loop devices, DM, or MD are
involved) etc. But blocking direct modifications of the block
device page cache is enough to give filesystems a chance to perform
data validation when loading data from the underlying storage and
thus prevent kernel crashes.
Syzbot can use this cmdline argument option to avoid uninteresting
crashes. Also users whose userspace setup does not need writing to
mounted block devices can set this option for hardening. We expect
that this will be interesting to quite a few workloads.
Btrfs is currently opted out of this because they still haven't
merged patches we require for this to work from three kernel
releases ago.
- Reimplement block device freezing and thawing as holder operations
on the block device.
This allows us to extend block device freezing to all devices
associated with a superblock and not just the main device. It also
allows us to remove get_active_super() and thus another function
that scans the global list of superblocks.
Freezing via additional block devices only works if the filesystem
chooses to use @fs_holder_ops for these additional devices as well.
That currently only includes ext4 and xfs.
Earlier releases switched get_tree_bdev() and mount_bdev() to use
@fs_holder_ops. The remaining nilfs2 open-coded version of
mount_bdev() has been converted to rely on @fs_holder_ops as well.
So block device freezing for the main block device will continue to
work as before.
There should be no regressions in functionality. The only special
case is btrfs where block device freezing for the main block device
never worked because sb->s_bdev isn't set. Block device freezing
for btrfs can be fixed once they can switch to @fs_holder_ops but
that can happen whenever they're ready"

Since commit aa49c90894d0 ("i2c: core: Run atomic i2c xfer when

is using atomic i2c xfer, as !preemptible() always results to 1.
During device_shutdown(), the i2c might be used a lot and not all busses
have implemented an atomic xfer handler. This results in a lot of
avoidable noise, like:
[ 12.687169] No atomic I2C transfer handler for 'i2c-0'

to the message passing code and a subsequent fix for eDP panel turn
on, that means my laptop can turn on the panel in GSP mode. These are
fairly low chance of disrupting things since GSP is new in 6.7. The
final not all in GSP fix is a deadlock seen with i915/nouveau when GSP
is used where the the fence and irq paths have locking inversions,
I've pushed some irq enablement out to a workqueue, and this has seen
some fairly decent testing.

ASM108x/VT630x PCIe cards
VIA VT6306/6307/6308 provides PCI interface compliant to 1394 OHCI. When
the hardware is combined with Asmedia ASM1083/1085 PCIe-to-PCI bus bridge,
it appears that accesses to its 'Isochronous Cycle Timer' register (offset
0xf0 on PCI memory space) often causes unexpected system reboot in any
type of AMD Ryzen machine (both 0x17 and 0x19 families). It does not
appears in the other type of machine (AMD pre-Ryzen machine, Intel
machine, at least), or in the other OHCI 1394 hardware (e.g. Texas
Instruments).
The issue explicitly appears at a commit dcadfd7f7c74 ("firewire: core:
use union for callback of transaction completion") added to v6.5 kernel.
It changed 1394 OHCI driver to access to the register every time to
dispatch local asynchronous transaction. However, the issue exists in
older version of kernel as long as it runs in AMD Ryzen machine, since
the access to the register is required to maintain bus time. It is not
hard to imagine that users experience the unexpected system reboot when
generating bus reset by plugging any devices in, or reading the register
by time-aware application programs; e.g. audio sample processing.
This commit suppresses the unexpected system reboot in the combination of
hardware. It avoids the access itself. As a result, the software stack can
not provide the hardware time anymore to unit drivers, userspace
applications, and nodes in the same IEEE 1394 bus. It brings apparent
disadvantage since time-aware application programs require it, while
time-unaware applications are available again; e.g. sbp2.

It's not safe to call nfsd_put once nfsd_last_thread has been called, as
that function will zero out the nn->nfsd_serv pointer.
Drop the nfsd_put helper altogether and open-code the svc_put in its
callers instead. That allows us to not be reliant on the value of that
pointer when handling an error.

Turns out that one of the ways that Nvidia's driver handles the pre-LT
timeout for eDP panels is by providing a retry timeout in their link
training callbacks that we're expected to wait for. Up until now we didn't
pay any attention to this parameter.
So, start honoring the timeout if link training fails - and retry up to 3
times. The "3 times" bit comes from OpenRM's link training code.

There is a deadlock between the irq and fctx locks,
the irq handling takes irq then fctx lock
the fence signalling takes fctx then irq lock
This splits the fence signalling path so the code that hits
the irq lock is done in a separate work queue.
This seems to fix crashes/hangs when using nouveau gsp with
i915 primary GPU.

Currently we get an error from ACPI because both of these arguments expect
a single argument, and we don't provide one. I'm not totally clear on what
that argument does, but we're able to find the missing value from
_acpiCacheMethodData() in src/kernel/platform/acpi_common.c in nvidia's
driver. So, let's add that - which doesn't get eDP displays to power on
quite yet, but gets rid of the argument warning at least.

Commit 688eb8191b47 ("x86/csum: Improve performance of `csum_partial`")
ended up improving the code generation for the IP csum calculations, and
in particular special-casing the 40-byte case that is a hot case for
IPv6 headers.
It then had _another_ special case for the 64-byte unrolled loop, which
did two chains of 32-byte blocks, which allows modern CPU's to improve
performance by doing the chains in parallel thanks to renaming the carry
flag.
This just unifies the special cases and combines them into just one
single helper the 40-byte csum case, and replaces the 64-byte case by a
80-byte case that just does that single helper twice. It avoids having
all these different versions of inline assembly, and actually improved
performance further in my tests.
There was never anything magical about the 64-byte unrolled case, even
though it happens to be a common size (and typically is the cacheline
size).

The special case for odd aligned buffers is unnecessary and mostly
just adds overhead. Aligned buffers is the expectations, and even for
unaligned buffer, the only case that was helped is if the buffer was
1-byte from word aligned which is ~1/7 of the cases. Overall it seems
highly unlikely to be worth to extra branch.
It was left in the previous perf improvement patch because I was
erroneously comparing the exact output of `csum_partial(...)`, but
really we only need `csum_fold(csum_partial(...))` to match so its
safe to remove.
All csum kunit tests pass.

This reverts commit b28ff7a7c3245d7f62acc20f15b4361292fe4117.
The commit introduced P2SB device scan and resource cache during the
boot process to avoid deadlock. But it caused detection failure of
IDE controllers on old systems [1]. The IDE controllers on old systems
and P2SB devices on newer systems have same PCI DEVFN. It is suspected
the confusion between those two is the failure cause. Revert the change
at this moment until the proper solution gets ready.

~cpuc->intel_ctrl_host_mask & ~pebs_mask. The intent is to always treat
PEBS events as host-only because, while the guest runs, there is no way
to tell the processor about the virtual address where to put PEBS records
intended for the host.
Unfortunately, the new expression can be expanded to
(intel_ctrl & ~cpuc->intel_ctrl_host_mask) | (intel_ctrl & ~pebs_mask)
which makes no sense; it includes any bit that isn't *both* marked as
exclude_guest and using PEBS. So, reinstate the old logic. Another
way to write it could be "intel_ctrl & ~(cpuc->intel_ctrl_host_mask |
pebs_mask)", presumably the intention of the author of the faulty.
However, I personally find the repeated application of A AND NOT B to
be a bit more readable.
This shows up as guest failures when running concurrent long-running
perf workloads on the host, and was reported to happen with rcutorture.
All guests on a given host would die simultaneously with something like an
instruction fault or a segmentation violation.

without PSR
The check for sending the vsc infopacket to the display was gated behind
PSR (Panel Self Refresh) being enabled.
The vsc infopacket also contains the colorimetry (specifically the
container color gamut) information for the stream on modern DP.
PSR is typically only supported on mobile phone eDP displays, thus this
was not getting sent for typical desktop monitors or TV screens.
This functionality is needed for proper HDR10 functionality on DP as it
wants BT2020 RGB/YCbCr for the container color space.

CSR.OPS bits specify the current operating mode and (according to
documentation) they are updated by HW when the operating mode change
request is processed. To comply with this check CSR.OPS before proceeding.
Commit introduces ravb_set_opmode() that does all the necessities for
setting the operating mode (set CCC.OPC (and CCC.GAC, CCC.CSEL, if any) and
wait for CSR.OPS) and call it where needed. This should comply with all the
HW manuals requirements as different manual variants specify that different
modes need to be checked in CSR.OPS when setting CCC.OPC.
If gPTP active in config mode is supported and it needs to be enabled, the
CCC.GAC and CCC.CSEL needs to be configured along with CCC.OPC in the same
write access. For this, ravb_set_opmode() allows passing GAC and CSEL as
part of opmode and the function updates accordingly CCC register.

During QoS scheduling testing with multiple strict priority flows, the
netdev tx watchdog timeout routine is invoked when a low priority QoS
queue doesn't get a chance to transmit the packets because other high
priority flows are completely subscribing the transmit link. The netdev
tx watchdog timeout routine will stop MAC RX and TX functionality in
otx2_stop() routine before cleanup of HW TX queues which results in SMQ
flush errors because the packets belonging to low priority queues will
never gets flushed since MAC TX is disabled. This patch fixes the issue
by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed
properly.

Currently the NIX TX link credits are initialized based on the max frame
size that can be transmitted on a link but when the MTU is changed, the
NIX TX link credits are reprogrammed by the SW based on the new MTU value.
Since SMQ max packet length is programmed to max frame size by default,
there is a chance that NIX TX may stall while sending a max frame sized
packet on the link with insufficient credits to send the packet all at
once. This patch avoids stall issue by not changing the link credits
dynamically when the MTU is changed.

When running the instruction decoder selftest with LLVM=1 and

arch/x86/tools/insn_decoder_test: warning: ffffffff81000050 ea <unknown>

arch/x86/tools/insn_decoder_test: warning: Decoded and checked 7214721 instructions with 1 failures
GNU objdump outputs "(bad)" instead of "<unknown>", which is already
handled in the bad_expr regex, so there is no warning.
$ objdump -d arch/x86/platform/pvh/head.o | grep -E '50:\s+ea'
50: ea (bad)
$ llvm-objdump -d arch/x86/platform/pvh/head.o | grep -E '50:\s+ea'

Add "<unknown>" to the bad_expr regex to clear up the warning, allowing
the instruction decoder selftest to fully pass with llvm-objdump.

kprobe_emulate_call_indirect
kprobe_emulate_call_indirect currently uses int3_emulate_call to emulate
indirect calls. However, int3_emulate_call always assumes the size of
the call to be 5 bytes when calculating the return address. This is
incorrect for register-based indirect calls in x86, which can be either
2 or 3 bytes depending on whether REX prefix is used. At kprobe runtime,
the incorrect return address causes control flow to land onto the wrong
place after return -- possibly not a valid instruction boundary. This
can lead to a panic like the following:

The relevant assembly code is (from objdump, faulting address

ffffffff8102eda0: 65 48 <8b> 05 30 c7 ff mov %gs:0x7effc730(%rip),%rax
The emulation incorrectly sets the return address to be ffffffff8102ed9d
+ 0x5 = ffffffff8102eda2, which is the 8b byte in the middle of the next
mov. This in turn causes incorrect subsequent instruction decoding and
eventually triggers the page fault above.
Instead of invoking int3_emulate_call, perform push and jmp emulation
directly in kprobe_emulate_call_indirect. At this point we can obtain
the instruction size from p->ainsn.size so that we can calculate the
correct return address.

A crash was found when dumping SMC-R connections. It can be reproduced
by following steps:
- environment: two RNICs on both sides.
- run SMC-R between two sides, now a SMC_LGR_SYMMETRIC type link group
will be created.
- set the first RNIC down on either side and link group will turn to
SMC_LGR_ASYMMETRIC_LOCAL then.
- run 'smcss -R' and the crash will be triggered.

For rq, we have three cases getting buffers from virtio core:
1. virtqueue_get_buf{,_ctx}
2. virtqueue_detach_unused_buf
3. callback for virtqueue_resize
But in commit 295525e29a5b("virtio_net: merge dma operations when
filling mergeable buffers"), I missed the dma unmap for the #3 case.
That will leak some memory, because I did not release the pages referred
by the unused buffers.
If we do such script, we will make the system OOM.

apparmor: Fix move_mount mediation by detecting if source is detached
|
|
Prevent move_mount from applying the attach_disconnected flag
to move_mount(). This prevents detached mounts from appearing
as / when applying mount mediation, which is not only incorrect
but could result in bad policy being generated.
Basic mount rules like
allow mount,
allow mount options=(move) -> /target/,
will allow detached mounts, allowing older policy to continue
to function. New policy gains the ability to specify `detached` as
a source option
allow mount detached -> /target/,
In addition make sure support of move_mount is advertised as
a feature to userspace so that applications that generate policy
can respond to the addition.
Note: this fixes mediation of move_mount when a detached mount is used,
it does not fix the broader regression of apparmor mediation of
mounts under the new mount api.

Pull tracing fixes from Steven Rostedt:
- Fix a NULL kernel dereference in set_gid() on tracefs mounting.
When tracefs is mounted with "gid=1000", it will update the existing
dentries to have the new gid. The tracefs_inode which is retrieved by
a container_of(dentry->d_inode) has flags to see if the inode belongs
to the eventfs system.
The issue that was fixed was if getdents() was called on tracefs that
was previously mounted, and was not closed. It will leave a "cursor
dentry" in the subdirs list of the current dentries that set_gid()
walks. On a remount of tracefs, the container_of(dentry->d_inode)
will dereference a NULL pointer and cause a crash when referenced.
Simply have a check for dentry->d_inode to see if it is NULL and if
so, skip that entry.
- Fix the bits of the eventfs_inode structure.
The "is_events" bit was taken from the nr_entries field, but the
nr_entries field wasn't updated to be 30 bits and was still 31.
Including the "is_freed" bit this would use 33 bits which would make
the structure use another integer for just one bit.

According to the Intel Software Manual for I225, Section 7.5.2.7,
hicredit should be multiplied by the constant link-rate value, 0x7736.
Currently, the old constant link-rate value, 0x7735, from the boards
supported on igb are being used, most likely due to a copy'n'paste, as
the rest of the logic is the same for both drivers.
Update hicredit accordingly.

During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability
register will be cleared. This can lead to issues when a VF is
assigned to a VM because in these cases the VF driver receives no
indication of the PF PCI error/reset and additionally it is incapable
of restoring the cleared flag in the hypervisor configuration space
without fully reinitializing the driver interrupt functionality.
Since the VF driver is unable to easily resolve this condition on its own,
restore the VF MSI-X flag during the PF PCI reset handling.

by increasing refcount during update the VSI filter list to

When deleting an unicast FDB entry, the i40e driver will release
the mac_filter, and i40e_service_task will concurrently request
firmware to add the mac_filter, which will lead to the following
use-after-free issue.
Fix again for both netdev->uc and netdev->mc.

The current code flow is:
1. snd_hdac_device_register()
2. set parameters needed by the hdac driver
3. request_codec_module()
the hdac driver is probed at this point
During boot the codec drivers are not loaded when the hdac device is
registered, it is going to be probed later when loading the codec module,
which point the parameters are set.
On module remove/insert
rmmod snd_sof_pci_intel_tgl
modprobe snd_sof_pci_intel_tgl
The codec module remains loaded and the driver will be probed when the
hdac device is created right away, before the parameters for the driver
has been configured:
1. snd_hdac_device_register()
the hdac driver is probed at this point
2. set parameters needed by the hdac driver
3. request_codec_module()
will be a NOP as the module is already loaded
Move the snd_hdac_device_register() later, to be done right before
requesting the codec module to make sure that the parameters are all set
before the device is created:
1. set parameters needed by the hdac driver
2. snd_hdac_device_register()
3. request_codec_module()
This way at the hdac driver probe all parameters will be set in all cases.

Commit 86a7e0b69bd5 ("net: prevent rewrite of msg_name in
sock_sendmsg()") made sock_sendmsg save the incoming msg_name pointer
and restore it before returning, to insulate the caller against
msg_name being changed by the called code. If the address length
was also changed however, we may return with an inconsistent structure
where the length doesn't match the address, and attempts to reuse it may
lead to lost packets.
For example, a kernel that doesn't have commit 1c5950fc6fe9 ("udp6: fix
potential access to stale information") will replace a v4 mapped address
with its ipv4 equivalent, and shorten namelen accordingly from 28 to 16.
If the caller attempts to reuse the resulting msg structure, it will have
the original ipv6 (v4 mapped) address but an incorrect v4 length.

This fixes openvswitch's handling of nat packets in the related state.
In nf_ct_nat_execute(), which is called from nf_ct_nat(), ICMP/ICMPv6
packets in the IP_CT_RELATED or IP_CT_RELATED_REPLY state, which have
not been dropped, will follow the goto, however the placement of the
goto label means that updating the action bit field will be bypassed.
This causes ovs_nat_update_key() to not be called from ovs_ct_nat()
which means the openvswitch match key for the ICMP/ICMPv6 packet is not
updated and the pre-nat value will be retained for the key, which will
result in the wrong openflow rule being matched for that packet.
Move the goto label above where the action bit field is being set so
that it is updated in all cases where the packet is accepted.

in the TX path, where each descriptor corresponds to a single skbuff
fragment (or the skbuff head). This led to packets with no FCS appearing

always happen when using PACKET_MMAP/TPACKET (cf. tpacket_fill_skb() in

The MPTCP protocol does not expect that any other entity could change
the first subflow status when such socket is listening.
Unfortunately the TCP diag interface allows aborting any TCP socket,
including MPTCP listeners subflows. As reported by syzbot, that trigger
a WARN() and could lead to later bigger trouble.
The MPTCP protocol needs to do some MPTCP-level cleanup actions to
properly shutdown the listener. To keep the fix simple, prevent
entirely the diag interface from stopping such listeners.
We could refine the diag callback in a later, larger patch targeting
net-next.

A flag was needed to denote which eventfs_inode was the "events"
directory, so a bit was taken from the "nr_entries" field, as there's not
that many entries, and 2^30 is plenty. But the bit number for nr_entries
was not updated to reflect the bit taken from it, which would add an
unnecessary integer to the structure.

If a getdents() is called on the tracefs directory but does not get all
the files, it can leave a "cursor" dentry in the d_subdirs list of tracefs
dentry. This cursor dentry does not have a d_inode for it. Before
referencing tracefs_inode from the dentry, the d_inode must first be
checked if it has content. If not, then it's not a tracefs_inode and can
be ignored.
The following caused a crash:
#define getdents64(fd, dirp, count) syscall(SYS_getdents64, fd, dirp, count)
#define BUF_SIZE 256
#define TDIR "/tmp/file0"
int main(void)
{
char buf[BUF_SIZE];
int fd;
int n;
mkdir(TDIR, 0777);
mount(NULL, TDIR, "tracefs", 0, NULL);
fd = openat(AT_FDCWD, TDIR, O_RDONLY);
n = getdents64(fd, buf, BUF_SIZE);
ret = mount(NULL, TDIR, NULL, MS_NOSUID|MS_REMOUNT|MS_RELATIME|MS_LAZYTIME,
"gid=1000");
return 0;
}
That's because the 256 BUF_SIZE was not big enough to read all the
dentries of the tracefs file system and it left a "cursor" dentry in the
subdirs of the tracefs root inode. Then on remounting with "gid=1000",
it would cause an iteration of all dentries which hit:
ti = get_tracefs(dentry->d_inode);
if (ti && (ti->flags & TRACEFS_EVENT_INODE))
eventfs_update_gid(dentry, gid);
Which crashed because of the dereference of the cursor dentry which had a NULL
d_inode.
In the subdir loop of the dentry lookup of set_gid(), if a child has a
NULL d_inode, simply skip it.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

When KASLR is enabled, the KASLR_FLAG bit in boot_params->hdr.loadflags
should be set to 1 to propagate KASLR status from compressed kernel to
kernel, just as the choose_random_location() function does.
Currently, when the kernel is booted via the EFI stub, the KASLR_FLAG
bit in boot_params->hdr.loadflags is not set, even though it should be.
This causes some functions, such as kernel_randomize_memory(), not to
execute as expected. Fix it.

Commit 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW") added the new
socket option SO_TIMESTAMPING_NEW. Setting the option is handled in
sk_setsockopt(), querying it was not handled in sk_getsockopt(), though.
Following remarks on an earlier submission of this patch, keep the old
behavior of getsockopt(SO_TIMESTAMPING_OLD) which returns the active
flags even if they actually have been set through SO_TIMESTAMPING_NEW.
The new getsockopt(SO_TIMESTAMPING_NEW) is stricter, returning flags
only if they have been set through the same option.

When a 'DEL_CLIENT' message is received from the remote, the corresponding
server port gets deleted. A DEL_SERVER message is then announced for this
server. As part of handling the subsequent DEL_SERVER message, the name-
server attempts to delete the server port which results in a '-ENOENT' error.
The return value from server_del() is then propagated back to qrtr_ns_worker,
causing excessive error prints.
To address this, return 0 from control_cmd_del_server() without checking the
return value of server_del(), since the above scenario is not an error case
and hence server_del() doesn't have any other error return value.

Add a new superblock section that contains a list of
{ minor version, recovery passes, errors_to_fix }
that is - a list of recovery passes that must be run when downgrading
past a given version, and a list of errors to silently fix.
The upcoming disk accounting rewrite is not going to be fully
compatible: we're going to have to regenerate accounting both when
upgrading to the new version, and also from downgrading from the new
version, since the new method of doing disk space accounting is a
completely different architecture based on deltas, and synchronizing
them for every jounal entry write to maintain compatibility is going to
be too expensive and impractical.

Add two new superblock fields. Since the main section of the superblock
is now fully, we have to add a new variable length section for them -
bch_sb_field_ext.
- recovery_passes_requried: recovery passes that must be run on the
next mount
- errors_silent: errors that will be silently fixed
These are to improve upgrading and dwongrading: these fields won't be
cleared until after recovery successfully completes, so there won't be
any issues with crashing partway through an upgrade or a downgrade.

peek_upto() checks against the end position and bails out before
FILTER_SNAPSHOTS checks; this is because if we end up at a different
inode number than the original search key none of the keys we see might
be visibile in the current snapshot - we might be looking at inode in a
completely different subvolume.
But this is broken, because when we're iterating over extents we're
checking against the extent start position to decide when to bail out,
and the extent start position isn't monotonically increasing until after
we've run FILTER_SNAPSHOTS.
Fix this by adding a simple inode number check where the old bailout
check was, and moving the main check to the correct position.

When parsing emails from .yaml files in particular, stray punctuation
such as a leading '-' can end up in the name. For example, consider a
common YAML section such as:
maintainers:
- devicetree@vger.kernel.org
This would previously be processed by get_maintainer.pl as:
- <devicetree@vger.kernel.org>
Make the logic in clean_file_emails more robust by deleting any
sub-names which consist of common single punctuation marks before
proceeding to the best-effort name extraction logic. The output is then
correct:
devicetree@vger.kernel.org
Some additional comments are added to the function to make things
clearer to future readers.

While the script correctly extracts UTF-8 encoded names from the
MAINTAINERS file, the regular expressions damage my name when parsing
from .yaml files. Fix this by replacing the Latin-1-compatible regular
expressions with the unicode property matcher \p{L}, which matches on
any letter according to the Unicode General Category of letters.
The proposed solution only works if the script uses proper string
encoding from the outset, so instruct Perl to unconditionally open all
files with UTF-8 encoding. This should be safe, as the entire source
tree is either UTF-8 or ASCII encoded anyway. See [1] for a detailed
analysis.
Furthermore, to prevent the \w expression from matching non-ASCII when
checking for whether a name should be escaped with quotes, add the /a
flag to the regular expression. The escaping logic was duplicated in
two places, so it has been factored out into its own function.
The original issue was also identified on the tools mailing list [2].
This should solve the observed side effects there as well.

Pull tracing fixes from Steven Rostedt:
- Fix readers that are blocked on the ring buffer when buffer_percent
is 100%. They are supposed to wake up when the buffer is full, but
because the sub-buffer that the writer is on is never considered
"dirty" in the calculation, dirty pages will never equal nr_pages.
Add +1 to the dirty count in order to count for the sub-buffer that
the writer is on.
- When a reader is blocked on the "snapshot_raw" file, it is to be
woken up when a snapshot is done and be able to read the snapshot
buffer. But because the snapshot swaps the buffers (the main one with
the snapshot one), and the snapshot reader is waiting on the old
snapshot buffer, it was not woken up (because it is now on the main
buffer after the swap). Worse yet, when it reads the buffer after a
snapshot, it's not reading the snapshot buffer, it's reading the live
active main buffer.
Fix this by forcing a wakeup of all readers on the snapshot buffer
when a new snapshot happens, and then update the buffer that the
reader is reading to be back on the snapshot buffer.
- Fix the modification of the direct_function hash. There was a race
when new functions were added to the direct_function hash as when it
moved function entries from the old hash to the new one, a direct
function trace could be hit and not see its entry.
This is fixed by allocating the new hash, copy all the old entries
onto it as well as the new entries, and then use rcu_assign_pointer()
to update the new direct_function hash with it.
This also fixes a memory leak in that code.
- Fix eventfs ownership

Masami Hiramatsu reported a memory leak in register_ftrace_direct() where
if the number of new entries are added is large enough to cause two
allocations in the loop:
for (i = 0; i < size; i++) {
hlist_for_each_entry(entry, &hash->buckets[i], hlist) {
new = ftrace_add_rec_direct(entry->ip, addr, &free_hash);
if (!new)
goto out_remove;
entry->direct = addr;
}
}
Where ftrace_add_rec_direct() has:
if (ftrace_hash_empty(direct_functions) ||
direct_functions->count > 2 * (1 << direct_functions->size_bits)) {
struct ftrace_hash *new_hash;
int size = ftrace_hash_empty(direct_functions) ? 0 :
direct_functions->count + 1;
if (size < 32)
size = 32;
new_hash = dup_hash(direct_functions, size);
if (!new_hash)
return NULL;
*free_hash = direct_functions;
direct_functions = new_hash;
}
The "*free_hash = direct_functions;" can happen twice, losing the previous
allocation of direct_functions.
But this also exposed a more serious bug.
The modification of direct_functions above is not safe. As
direct_functions can be referenced at any time to find what direct caller
it should call, the time between:
new_hash = dup_hash(direct_functions, size);
and
direct_functions = new_hash;
can have a race with another CPU (or even this one if it gets interrupted),
and the entries being moved to the new hash are not referenced.
That's because the "dup_hash()" is really misnamed and is really a
"move_hash()". It moves the entries from the old hash to the new one.
Now even if that was changed, this code is not proper as direct_functions
should not be updated until the end. That is the best way to handle
function reference changes, and is the way other parts of ftrace handles
this.
The following is done:
1. Change add_hash_entry() to return the entry it created and inserted
into the hash, and not just return success or not.
2. Replace ftrace_add_rec_direct() with add_hash_entry(), and remove
the former.
3. Allocate a "new_hash" at the start that is made for holding both the
new hash entries as well as the existing entries in direct_functions.
4. Copy (not move) the direct_function entries over to the new_hash.
5. Copy the entries of the added hash to the new_hash.
6. If everything succeeds, then use rcu_pointer_assign() to update the
direct_functions with the new_hash.
This simplifies the code and fixes both the memory leak as well as the
race condition mentioned above.

Under heavy traffic, the BlueField Gigabit interface can
become unresponsive. This is due to a possible race condition
in the mlxbf_gige_rx_packet function, where the function exits
with producer and consumer indices equal but there are remaining
packet(s) to be processed. In order to prevent this situation,
read receive consumer index *before* the HW replenish so that
the mlxbf_gige_rx_packet function returns an accurate return
value even if a packet is received into just-replenished buffer
prior to exiting this routine. If the just-replenished buffer
is received and occupies the last RX ring entry, the interface
would not recover and instead would encounter RX packet drops
related to internal buffer shortages since the driver RX logic
is not being triggered to drain the RX ring. This patch will
address and prevent this "ring full" condition.

A test [1] in Android test suite started failing after [2] was merged. It
turns out that after handling a major fault under per-VMA lock, the
process major fault counter does not register that fault as major. Before
[2] read faults would be done under mmap_lock, in which case
FAULT_FLAG_TRIED flag is set before retrying. That in turn causes
mm_account_fault() to account the fault as major once retry completes.
With per-VMA locks we often retry because a fault can't be handled without
locking the whole mm using mmap_lock. Therefore such retries do not set
FAULT_FLAG_TRIED flag. This logic does not work after [2] because we can
now handle read major faults under per-VMA lock and upon retry the fact
there was a major fault gets lost. Fix this by setting FAULT_FLAG_TRIED
after retrying under per-VMA lock if VM_FAULT_MAJOR was returned. Ideally
we would use an additional VM_FAULT bit to indicate the reason for the
retry (could not handle under per-VMA lock vs other reason) but this
simpler solution seems to work, so keeping it simple.

Special VMAs like VM_PFNMAP can contain anon pages from COW. There isn't
much profit in doing lookaround on them. Besides, they can trigger the
pte_special() warning in get_pte_pfn().
Skip them in lru_gen_look_around().

The bug happens when highest bit of holebegin is 1, suppose holebegin is
0x8000000111111000, after shift, hba would be 0xfff8000000111111, then
vma_interval_tree_foreach would look it up fail or leads to the wrong
result.
error call seq e.g.:
- mmap(..., offset=0x8000000111111000)
|- syscall(mmap, ... unsigned long, off):
|- ksys_mmap_pgoff( ... , off >> PAGE_SHIFT);
here pgoff is correctly shifted to 0x8000000111111,
but pass 0x8000000111111000 as holebegin to unmap
would then cause terrible result, as shown below:
- unmap_mapping_range(..., loff_t const holebegin)
|- pgoff_t hba = holebegin >> PAGE_SHIFT;
/* hba = 0xfff8000000111111 unexpectedly */
The issue happens in Heterogeneous computing, where the device(e.g.
gpu) and host share the same virtual address space.
A simple workflow pattern which hit the issue is:
/* host */
1. userspace first mmap a file backed VA range with specified offset.
e.g. (offset=0x800..., mmap return: va_a)
2. write some data to the corresponding sys page
e.g. (va_a = 0xAABB)
/* device */
3. gpu workload touches VA, triggers gpu fault and notify the host.
/* host */
4. reviced gpu fault notification, then it will:
4.1 unmap host pages and also takes care of cpu tlb
(use unmap_mapping_range with offset=0x800...)
4.2 migrate sys page to device
4.3 setup device page table and resolve device fault.
/* device */
5. gpu workload continued, it accessed va_a and got 0xAABB.
6. gpu workload continued, it wrote 0xBBCC to va_a.
/* host */
7. userspace access va_a, as expected, it will:
7.1 trigger cpu vm fault.
7.2 driver handling fault to migrate gpu local page to host.
8. userspace then could correctly get 0xBBCC from va_a
9. done
But in step 4.1, if we hit the bug this patch mentioned, then userspace
would never trigger cpu fault, and still get the old value: 0xAABB.
Making holebegin unsigned first fixes the bug.

The reason for the crash is that, the commit 85ce2c517ade ("memcontrol:
only transfer the memcg data for migration") removed the charging and
uncharging operations of the migration folios and cleared the memcg data
of the old folio.
During the subsequent release process of the old large folio in
destroy_large_folio(), if the large folio needs to be removed from the
split queue, an incorrect split queue can be obtained (which is
pgdat->deferred_split_queue) because the old folio's memcg is NULL now.
This can lead to list operations being performed under the wrong split
queue lock protection, resulting in a list crash as above.
After the migration, the old folio is going to be freed, so we can remove
it from the split queue in mem_cgroup_migrate() a bit earlier before
clearing the memcg data to avoid getting incorrect split queue.
