f2fs: call f2fs_handle_critical_error() to set cp_error flag
f2fs_handle_page_eio() is the only left place we set CP_ERROR_FLAG
directly, it missed to update superblock.s_stop_reason, let's
call f2fs_handle_critical_error() instead to fix that.
Introduce STOP_CP_REASON_READ_{META,NODE,DATA} stop_cp_reason enum
variable to indicate which kind of data we failed to read.

tracing fixes for 7.0:
- Revert "tracing: Remove pid in task_rename tracing output" A change was made to remove the pid field from the task_rename event because it was thought that it was always done for the current task and recording the pid would be redundant. This turned out to be incorrect and there are a few corner case where this is not true and caused some regressions in tooling. - Fix the reading from user space for migration The reading of user space uses a seq lock type of logic where it uses a per-cpu temporary buffer and disables migration, then enables preemption, does the copy from user space, disables preemption, enables migration and checks if there was any schedule switches while preemption was enabled. If there was a context switch, then it is considered that the per-cpu buffer could be corrupted and it tries again. There's a protection check that tests if it takes a hundred tries, it issues a warning and exits out to prevent a live lock. This was triggered because the task was selected by the load balancer to be migrated to another CPU, every time preemption is enabled the migration task would schedule in try to migrate the task but can't because migration is disabled and let it run again. This caused the scheduler to schedule out the task every time it enabled preemption and made the loop never exit (until the 100 iteration test triggered). Fix this by enabling and disabling preemption and keeping migration enabled if the reading from user space needs to be done again. This will let the migration thread migrate the task and the copy from user space will likely pass on the next iteration. - Fix trace_marker copy option freeing The "copy_trace_marker" option allows a tracing instance to get a copy of a write to the trace_marker file of the top level instance. This is managed by a link list protected by RCU. When an instance is removed, a check is made if the option is set, and if so synchronized_rcu() is called. The problem is that an iteration is made to reset all the flags to what they were when the instance was created (to perform clean ups) was done before the check of the copy_trace_marker option and that option was cleared, so the synchronize_rcu() was never called. Move the clearing of all the flags after the check of copy_trace_marker to do synchronize_rcu() so that the option is still set if it was before and the synchronization is performed. - Fix entries setting when validating the persistent ring buffer When validating the persistent ring buffer on boot up, the number of events per sub-buffer is added to the sub-buffer meta page. The validator was updating cpu_buffer->head_page (the first sub-buffer of the per-cpu buffer) and not the "head_page" variable that was iterating the sub-buffers. This was causing the first sub-buffer to be assigned the entries for each sub-buffer and not the sub-buffer that was supposed to be updated. - Use "hash" value to update the direct callers When updating the ftrace direct callers, it assigned a temporary callback to all the callback functions of the ftrace ops and not just the functions represented by the passed in hash. This causes an unnecessary slow down of the functions of the ftrace_ops that is not being modified. Only update the functions that are going to be modified to call the ftrace loop function so that the update can be made on those functions. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCacAMahQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qr0sAQCoI4L3iAR5HU1z8dw2GWhOz9fTnzfw 9VPRZAsga9J5xgEA1Y0bvKBM0UPHFAL2POkaILYV1aT00lZ7aIVHPqfdYgA= =OoGW -----END PGP SIGNATURE----- Merge tag 'trace-v7.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Revert "tracing: Remove pid in task_rename tracing output" A change was made to remove the pid field from the task_rename event because it was thought that it was always done for the current task and recording the pid would be redundant.

mm/damon/core: avoid use of half-online-committed context
One major usage of damon_call() is online DAMON parameters update. It is
done by calling damon_commit_ctx() inside the damon_call() callback
function. damon_commit_ctx() can fail for two reasons: 1) invalid
parameters and 2) internal memory allocation failures. In case of
failures, the damon_ctx that attempted to be updated (commit destination)
can be partially updated (or, corrupted from a perspective), and therefore
shouldn't be used anymore. The function only ensures the damon_ctx object
can safely deallocated using damon_destroy_ctx().
The API callers are, however, calling damon_commit_ctx() only after
asserting the parameters are valid, to avoid damon_commit_ctx() fails due
to invalid input parameters. But it can still theoretically fail if the
internal memory allocation fails. In the case, DAMON may run with the
partially updated damon_ctx. This can result in unexpected behaviors
including even NULL pointer dereference in case of damos_commit_dests()
failure [1]. Such allocation failure is arguably too small to fail, so
the real world impact would be rare. But, given the bad consequence, this
needs to be fixed.
Avoid such partially-committed (maybe-corrupted) damon_ctx use by saving
the damon_commit_ctx() failure on the damon_ctx object. For this,
introduce damon_ctx->maybe_corrupted field. damon_commit_ctx() sets it
when it is failed. kdamond_call() checks if the field is set after each
damon_call_control->fn() is executed. If it is set, ignore remaining
callback requests and return. All kdamond_call() callers including
kdamond_fn() also check the maybe_corrupted field right after
kdamond_call() invocations. If the field is set, break the kdamond_fn()
main loop so that DAMON sill doesn't use the context that might be
corrupted.
[sj@kernel.org: let kdamond_call() with cancel regardless of maybe_corrupted]

xen/privcmd: add boot control for restricted usage in domU
When running in an unprivileged domU under Xen, the privcmd driver is restricted to allow only hypercalls against a target domain, for which the current domU is acting as a device model. Add a boot parameter "unrestricted" to allow all hypercalls (the hypervisor will still refuse destructive hypercalls affecting other guests). Make this new parameter effective only in case the domU wasn't started using secure boot, as otherwise hypercalls targeting the domU itself might result in violating the secure boot functionality. This is achieved by adding another lockdown reason, which can be tested to not being set when applying the "unrestricted" option.

io_uring/kbuf: propagate BUF_MORE through early buffer commit path
When io_should_commit() returns true (eg for non-pollable files), buffer
commit happens at buffer selection time and sel->buf_list is set to
NULL. When __io_put_kbufs() generates CQE flags at completion time, it
calls __io_put_kbuf_ring() which finds a NULL buffer_list and hence
cannot determine whether the buffer was consumed or not. This means that
IORING_CQE_F_BUF_MORE is never set for non-pollable input with
incrementally consumed buffers.
Likewise for io_buffers_select(), which always commits upfront and
discards the return value of io_kbuf_commit().
Add REQ_F_BUF_MORE to store the result of io_kbuf_commit() during early
commit. Then __io_put_kbuf_ring() can check this flag and set
IORING_F_BUF_MORE accordingy.

udp_tunnel: fix NULL deref caused by udp_sock_create6 when CONFIG_IPV6=n
When CONFIG_IPV6 is disabled, the udp_sock_create6() function returns 0
(success) without actually creating a socket. Callers such as
fou_create() then proceed to dereference the uninitialized socket
pointer, resulting in a NULL pointer dereference.
The captured NULL deref crash:

wifi: mac80211: always free skb on ieee80211_tx_prepare_skb() failure
ieee80211_tx_prepare_skb() has three error paths, but only two of them
free the skb. The first error path (ieee80211_tx_prepare() returning
TX_DROP) does not free it, while invoke_tx_handlers() failure and the
fragmentation check both do.
Add kfree_skb() to the first error path so all three are consistent,
and remove the now-redundant frees in callers (ath9k, mt76,
mac80211_hwsim) to avoid double-free.
Document the skb ownership guarantee in the function's kdoc.

driver core: platform: use generic driver_override infrastructure
When a driver is probed through __driver_attach(), the bus' match()
callback is called without the device lock held, thus accessing the
driver_override field without a lock, which can cause a UAF.
Fix this by using the driver-core driver_override infrastructure taking
care of proper locking internally.
Note that calling match() from __driver_attach() without the device lock
held is intentional. [1]

driver core: generalize driver_override in struct device
Currently, there are 12 busses (including platform and PCI) that duplicate the driver_override logic for their individual devices. All of them seem to be prone to the bug described in [1]. While this could be solved for every bus individually using a separate lock, solving this in the driver-core generically results in less (and cleaner) changes overall. Thus, move driver_override to struct device, provide corresponding accessors for busses and handle locking with a separate lock internally. In particular, add device_set_driver_override(), device_has_driver_override(), device_match_driver_override() and generalize the sysfs store() and show() callbacks via a driver_override feature flag in struct bus_type. Until all busses have migrated, keep driver_set_override() in place. Note that we can't use the device lock for the reasons described in [2].

clsact: Fix use-after-free in init/destroy rollback asymmetry
Fix a use-after-free in the clsact qdisc upon init/destroy rollback asymmetry. The latter is achieved by first fully initializing a clsact instance, and then in a second step having a replacement failure for the new clsact qdisc instance. clsact_init() initializes ingress first and then takes care of the egress part. This can fail midway, for example, via tcf_block_get_ext(). Upon failure, the kernel will trigger the clsact_destroy() callback. Commit |

Workflow to reproduce:
1. Initialize a TEQL topology (dummy0 and ifb0 as slaves, teql0 up).
2. Start multiple sender workers continuously transmitting packets
through teql0 to drive teql_master_xmit().
3. In parallel, repeatedly delete and re-add the root qdisc on
dummy0 and ifb0 via RTNETLINK, forcing frequent teardown and reset activity
(teql_destroy() / qdisc_reset()).
4. After running both workloads concurrently for several iterations,
KASAN reports slab-use-after-free or double-free in the skb free path.
Fix this by moving dev_reset_queue to sch_generic.h and calling it, instead
of qdisc_reset, in teql_destroy since it handles both the lock and lockless
cases correctly for root qdiscs.

bonding: prevent potential infinite loop in bond_header_parse()
bond_header_parse() can loop if a stack of two bonding devices is setup,
because skb->dev always points to the hierarchy top.
Add new "const struct net_device *dev" parameter to
(struct header_ops)->parse() method to make sure the recursion
is bounded, and that the final leaf parse method is called.

ARM:
- Correctly handle deeactivation of interrupts that were activated from
LRs. Since EOIcount only denotes deactivation of interrupts that
are not present in an LR, start EOIcount deactivation walk *after*
the last irq that made it into an LR.
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when
pKVM is already enabled -- not only thhis isn't possible (pKVM
will reject the call), but it is also useless: this can only
happen for a CPU that has already booted once, and the capability
will not change.
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was exposed by
the recent conversion to kmalloc_obj(); rip out all the ugliness that
led to the wart.
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access,
float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked as
available whenever the kernel used scattered feature words for them.
- Validate _all_ GVAs, rather than just the first GVA, when processing
a range of GVAs for Hyper-V's TLB flush hypercalls.
- Fix a brown paper bug in add_atomic_switch_msr().
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu.
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local
APIC (and AVIC is enabled at the module level).
- Update CR8 write interception when AVIC is (de)activated, to fix a bug
where the guest can run in perpetuity with the CR8 intercept enabled.
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow
L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an
unintentional tightening of userspace ABI in 6.17, and provides some
amount of backwards compatibility with hypervisors who want to freeze
PMCs on VM-Entry.
- Validate the VMCS/VMCB on return to a nested guest from SMM, because
either userspace or the guest could stash invalid values in memory
and trigger the processor's consistency checks.
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being
unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end.
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite being
rather unintuitive.
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd selftest to
64 (from 8).

Pull kvm fixes from Paolo Bonzini:
"Quite a large pull request, partly due to skipping last week and
therefore having material from ~all submaintainers in this one. About
a fourth of it is a new selftest, and a couple more changes are large
in number of files touched (fixing a -Wflex-array-member-not-at-end
compiler warning) or lines changed (reformatting of a table in the API
documentation, thanks rST).
But who am I kidding---it's a lot of commits and there are a lot of
bugs being fixed here, some of them on the nastier side like the
RISC-V ones.

More MM-CID fixes, mostly fixing hangs/races:
- Fix CID hangs due to a race between concurrent forks
- Fix vfork()/CLONE_VM MMCID bug causing hangs
- Remove pointless preemption guard
- Fix CID task list walk performance regression on large systems
by removing the known-flaky and slow counting logic using
for_each_process_thread() in mm_cid_*fixup_tasks_to_cpus(),
and implementing a simple sched_mm_cid::node list instead

USB fixes for 7.0-rc4
Here is a large chunk of USB driver fixes for 7.0-rc4. Included in here
are:
- usb gadget reverts due to reported issues, and then a follow-on fix
to hopefully resolve the reported overall problem
- xhci driver fixes
- dwc3 driver fixes
- usb core "killable" bulk message api addition to fix a usbtmc driver
bug where userspace could hang the driver for forever
- small USB driver fixes for reported issues
- new usb device quirks
All except the last USB device quirk change have been in linux-next with
no reported issues. That one came in too late, and is "obviously
correct" :)

ip_tunnel: adapt iptunnel_xmit_stats() to NETDEV_PCPU_STAT_DSTATS
Blamed commits forgot that vxlan/geneve use udp_tunnel[6]_xmit_skb() which
call iptunnel_xmit_stats().
iptunnel_xmit_stats() was assuming tunnels were only using
NETDEV_PCPU_STAT_TSTATS.
@syncp offset in pcpu_sw_netstats and pcpu_dstats is different.
32bit kernels would either have corruptions or freezes if the syncp
sequence was overwritten.
This patch also moves pcpu_stat_type closer to dev->{t,d}stats to avoid
a potential cache line miss since iptunnel_xmit_stats() needs to read it.

serial: 8250: Add serial8250_handle_irq_locked()
8250_port exports serial8250_handle_irq() to HW specific 8250 drivers. It takes port's lock within but a HW specific 8250 driver may want to take port's lock itself, do something, and then call the generic handler in 8250_port but to do that, the caller has to release port's lock for no good reason. Introduce serial8250_handle_irq_locked() which a HW specific driver can call while already holding port's lock. As this is new export, put it straight into a namespace (where all 8250 exports should eventually be moved).

io_uring: ensure ctx->rings is stable for task work flags manipulation
If DEFER_TASKRUN | SETUP_TASKRUN is used and task work is added while
the ring is being resized, it's possible for the OR'ing of
IORING_SQ_TASKRUN to happen in the small window of swapping into the
new rings and the old rings being freed.
Prevent this by adding a 2nd ->rings pointer, ->rings_rcu, which is
protected by RCU. The task work flags manipulation is inside RCU
already, and if the resize ring freeing is done post an RCU synchronize,
then there's no need to add locking to the fast path of task work
additions.
Note: this is only done for DEFER_TASKRUN, as that's the only setup mode
that supports ring resizing. If this ever changes, then they too need to
use the io_ctx_mark_taskrun() helper.

usb: core: new quirk to handle devices with zero configurations
Some USB devices incorrectly report bNumConfigurations as 0 in their device descriptor, which causes the USB core to reject them during enumeration. logs: usb 1-2: device descriptor read/64, error -71 usb 1-2: no configurations usb 1-2: can't read configurations, error -22 However, these devices actually work correctly when treated as having a single configuration. Add a new quirk USB_QUIRK_FORCE_ONE_CONFIG to handle such devices. When this quirk is set, assume the device has 1 configuration instead of failing with -EINVAL. This quirk is applied to the device with VID:PID 5131:2007 which exhibits this behavior.

USB: core: Limit the length of unkillable synchronous timeouts
The usb_control_msg(), usb_bulk_msg(), and usb_interrupt_msg() APIs in
usbcore allow unlimited timeout durations. And since they use
uninterruptible waits, this leaves open the possibility of hanging a
task for an indefinitely long time, with no way to kill it short of
unplugging the target device.
To prevent this sort of problem, enforce a maximum limit on the length
of these unkillable timeouts. The limit chosen here, somewhat
arbitrarily, is 60 seconds. On many systems (although not all) this
is short enough to avoid triggering the kernel's hung-task detector.
In addition, clear up the ambiguity of negative timeout values by
treating them the same as 0, i.e., using the maximum allowed timeout.

The synchronous message API in usbcore (usb_control_msg(),
usb_bulk_msg(), and so on) uses uninterruptible waits. However,
drivers may call these routines in the context of a user thread, which
means it ought to be possible to at least kill them.
For this reason, introduce a new usb_bulk_msg_killable() function
which behaves the same as usb_bulk_msg() except for using
wait_for_completion_killable_timeout() instead of
wait_for_completion_timeout(). The same can be done later for
usb_control_msg() later on, if it turns out to be needed.

HID: input: Add HID_BATTERY_QUIRK_DYNAMIC for Elan touchscreens
Elan touchscreens have a HID-battery device for the stylus which is always there even if there is no stylus. This is causing upower to report an empty battery for the stylus and some desktop-environments will show a notification about this, which is quite annoying. Because of this the HID-battery is being ignored on all Elan I2c and USB touchscreens, but this causes there to be no battery reporting for the stylus at all. This adds a new HID_BATTERY_QUIRK_DYNAMIC and uses these for the Elan touchscreens. This new quirks causes the present value of the battery to start at 0, which will make userspace ignore it and only sets present to 1 after receiving a battery input report which only happens when the stylus gets in range.

sched/mmcid: Avoid full tasklist walks
Chasing vfork()'ed tasks on a CID ownership mode switch requires a full
task list walk, which is obviously expensive on large systems.
Avoid that by keeping a list of tasks using a mm MMCID entity in mm::mm_cid
and walk this list instead. This removes the proven to be flaky counting
logic and avoids a full task list walk in the case of vfork()'ed tasks.
