usb: core: Unregister device on component_add() failure
Commit 8c67d06f3fd9 ("usb: Link the ports to the connectors they are
attached to") creates a link to the USB Type-C connector for every new
port that is added when possible. If component_add() fails,
usb_hub_create_port_device() prints a warning but does not unregister
the device and does not return errors to the callers.
Syzbot reported a "WARNING in component_del()".
Fix this issue in usb_hub_create_port_device by calling device_unregister()
and returning the errors from component_add().

net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup
ax88179_rx_fixup() contains several out-of-bounds accesses that can be
triggered by a malicious (or defective) USB device, in particular:
- The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds,
causing OOB reads and (on big-endian systems) OOB endianness flips.
- A packet can overlap the metadata array, causing a later OOB
endianness flip to corrupt data used by a cloned SKB that has already
been handed off into the network stack.
- A packet SKB can be constructed whose tail is far beyond its end,
causing out-of-bounds heap data to be considered part of the SKB's
data.
I have tested that this can be used by a malicious USB device to send a
bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response
that contains random kernel heap data.
It's probably also possible to get OOB writes from this on a
little-endian system somehow - maybe by triggering skb_cow() via IP
options processing -, but I haven't tested that.

usb: dwc3: gadget: Prevent core from processing stale TRBs
With CPU re-ordering on write instructions, there might
be a chance that the HWO is set before the TRB is updated
with the new mapped buffer address.
And in the case where core is processing a list of TRBs
it is possible that it fetched the TRBs when the HWO is set
but before the buffer address is updated.
Prevent this by adding a memory barrier before the HWO
is updated to ensure that the core always process the
updated TRBs.

support both IN and OUT.
raw-gadget currently gets confused and thinks that any endpoint that is

Consider a case where ffs_func_eps_disable is called from

ffs_epfile_release will free up the read buffer and call
ffs_data_closed which in turn destroys ffs->epfiles and
mark it as NULL. While this was happening the driver has
already initialized the local epfile in ffs_func_eps_disable
which is now freed and waiting to acquire the spinlock. Once
spinlock is acquired the driver proceeds with the stale value
of epfile and tries to free the already freed read buffer
causing use-after-free.
Fix this races by taking epfiles local copy & assigning it under
spinlock and if epfiles(local) is null then update it in ffs->epfiles
then finally destroy it.
Extending the scope further from the race, protecting the ep related

No functionality is restored as no one actually has this hardware

efi: runtime: avoid EFIv2 runtime services on Apple x86 machines
efi/libstub: arm64: Fix image check alignment at entry
Core of the problem is that ceph checks for return code from
security_dentry_init_security() and if return code is 0, it assumes
everything is fine and continues to call strlen(name), which crashes.
Typically SELinux LSM returns 0 and sets name to "security.selinux" and
it is not a problem. Or if selinux is not compiled in or disabled, it
returns -EOPNOTSUP and ceph deals with it.
But somehow in this configuration, 0 is being returned and "name" is
not being initialized and that's creating the problem.
Our suspicion is that BPF LSM is registering a hook for
dentry_init_security() and returns hook default of 0.
I have not been able to reproduce it just by doing CONFIG_BPF_LSM=y.
Stephen has tested the patch though and confirms it solves the problem
for him.
dentry_init_security() is written in such a way that it expects only one
LSM to register the hook. Atleast that's the expectation with current code.
If another LSM returns a hook and returns default, it will simply return
0 as of now and that will break ceph.
Hence, suggestion is that change semantics of this hook a bit. If there
are no LSMs or no LSM is taking ownership and initializing security context,
then return -EOPNOTSUP. Also allow at max one LSM to initialize security
context. This hook can't deal with multiple LSMs trying to init security
context. This patch implements this new behavior.

Since kvm_unregister_irq_ack_notifier() does synchronize_srcu(&kvm->irq_srcu),
kvm->irq_ack_notifier_list is protected by kvm->irq_srcu. In fact,
kvm->irq_srcu SRCU read lock is held in kvm_notify_acked_irq(), making it

KVM: nVMX: Allow VMREAD when Enlightened VMCS is in use
Hyper-V TLFS explicitly forbids VMREAD and VMWRITE instructions when
Enlightened VMCS interface is in use:
"Any VMREAD or VMWRITE instructions while an enlightened VMCS is
active is unsupported and can result in unexpected behavior.""
Windows 11 + WSL2 seems to ignore this, attempts to VMREAD VMCS field
0x4404 ("VM-exit interruption information") are observed. Failing
these attempts with nested_vmx_failInvalid() makes such guests
unbootable.
Microsoft confirms this is a Hyper-V bug and claims that it'll get fixed
eventually but for the time being we need a workaround. (Temporary) allow
VMREAD to get data from the currently loaded Enlightened VMCS.
Note: VMWRITE instructions remain forbidden, it is not clear how to
handle them properly and hopefully won't ever be needed.

KVM: nVMX: Implement evmcs_field_offset() suitable for handle_vmread()
In preparation to allowing reads from Enlightened VMCS from
handle_vmread(), implement evmcs_field_offset() to get the correct
read offset. get_evmcs_offset(), which is being used by KVM-on-Hyper-V,
is almost what's needed but a few things need to be adjusted. First,
WARN_ON() is unacceptable for handle_vmread() as any field can (in
theory) be supplied by the guest and not all fields are defined in
eVMCS v1. Second, we need to handle 'holes' in eVMCS (missing fields).
It also sounds like a good idea to WARN_ON() if such fields are ever
accessed by KVM-on-Hyper-V.
Implement dedicated evmcs_field_offset() helper.

KVM: x86: add system attribute to retrieve full set of supported xsave states
Because KVM_GET_SUPPORTED_CPUID is meant to be passed (by simple-minded
VMMs) to KVM_SET_CPUID2, it cannot include any dynamic xsave states that
have not been enabled. Probing those, for example so that they can be
passed to ARCH_REQ_XCOMP_GUEST_PERM, requires a new ioctl or arch_prctl.
The latter is in fact worse, even though that is what the rest of the
API uses, because it would require supported_xcr0 to be moved from the
KVM module to the kernel just for this use. In addition, the value
would be nonsensical (or an error would have to be returned) until
the KVM module is loaded in.
Therefore, to limit the growth of system ioctls, add a /dev/kvm
variant of KVM_{GET,HAS}_DEVICE_ATTR, and implement it in x86
with just one group (0) and attribute (KVM_X86_XCOMP_GUEST_SUPP).

ftrace: Have architectures opt-in for mcount build time sorting
First S390 complained that the sorting of the mcount sections at build
time caused the kernel to crash on their architecture. Now PowerPC is
complaining about it too. And also ARM64 appears to be having issues.
It may be necessary to also update the relocation table for the values
in the mcount table. Not only do we have to sort the table, but also
update the relocations that may be applied to the items in the table.
If the system is not relocatable, then it is fine to sort, but if it is,
some architectures may have issues (although x86 does not as it shifts all
addresses the same).
Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is
safe to do the sorting at build time.
Also update the config to compile in build time sorting in the sorttable
code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.

TRBE implementations affected by Arm erratum #1902691 might corrupt trace

TRBE is broken and hence cannot be used to capture trace data. This adds

TRBE implementations affected by Arm erratum #2038923 might get TRBE into
an inconsistent view on whether trace is prohibited within the CPU. As a
result, the trace buffer or trace buffer state might be corrupted. This
happens after TRBE buffer has been enabled by setting TRBLIMITR_EL1.E,
followed by just a single context synchronization event before execution
changes from a context, in which trace is prohibited to one where it isn't,
or vice versa. In these mentioned conditions, the view of whether trace is
prohibited is inconsistent between parts of the CPU, and the trace buffer
or the trace buffer state might be corrupted. This adds a new errata
ARM64_ERRATUM_2038923 in arm64 errata framework.
arm64: errata: Add detection for TRBE ignored system register writes
TRBE implementations affected by Arm erratum #2064142 might fail to write
