commit ed40866ec7d328b3dfb70db7e2011640a16202c3 upstream.
s390's struct statfs and struct statfs64 contain padding, which
field-by-field copying does not set. Initialize the respective structs
with zeros before filling them and copying them to userspace, like it's
already done for the compat versions of these structs.

commit afb2acb2e3a32e4d56f7fbd819769b98ed1b7520 upstream.
In kvm_vm_ioctl_create_vcpu(), add vcpu to vcpu_array iff it's safe to
access vcpu via kvm_get_vcpu() and kvm_for_each_vcpu(), i.e. when there's
no failure path requiring vcpu removal and destruction. Such order is
important because vcpu_array accessors may end up referencing vcpu at
vcpu_array[0] even before online_vcpus is set to 1.
When online_vcpus=0, any call to kvm_get_vcpu() goes through
array_index_nospec() and ends with an attempt to xa_load(vcpu_array, 0):
int num_vcpus = atomic_read(&kvm->online_vcpus);
i = array_index_nospec(i, num_vcpus);
return xa_load(&kvm->vcpu_array, i);
Similarly, when online_vcpus=0, a kvm_for_each_vcpu() does not iterate over
an "empty" range, but actually [0, ULONG_MAX]:
xa_for_each_range(&kvm->vcpu_array, idx, vcpup, 0, \
(atomic_read(&kvm->online_vcpus) - 1))
In both cases, such online_vcpus=0 edge case, even if leading to
unnecessary calls to XArray API, should not be an issue; requesting
unpopulated indexes/ranges is handled by xa_load() and xa_for_each_range().
However, this means that when the first vCPU is created and inserted in
vcpu_array *and* before online_vcpus is incremented, code calling
kvm_get_vcpu()/kvm_for_each_vcpu() already has access to that first vCPU.
This should not pose a problem assuming that once a vcpu is stored in
vcpu_array, it will remain there, but that's not the case:
kvm_vm_ioctl_create_vcpu() first inserts to vcpu_array, then requests a
file descriptor. If create_vcpu_fd() fails, newly inserted vcpu is removed
from the vcpu_array, then destroyed:
vcpu->vcpu_idx = atomic_read(&kvm->online_vcpus);
r = xa_insert(&kvm->vcpu_array, vcpu->vcpu_idx, vcpu, GFP_KERNEL_ACCOUNT);
kvm_get_kvm(kvm);
r = create_vcpu_fd(vcpu);
if (r < 0) {
xa_erase(&kvm->vcpu_array, vcpu->vcpu_idx);
kvm_put_kvm_no_destroy(kvm);
goto unlock_vcpu_destroy;
}
atomic_inc(&kvm->online_vcpus);
This results in a possible race condition when a reference to a vcpu is
acquired (via kvm_get_vcpu() or kvm_for_each_vcpu()) moments before said
vcpu is destroyed.

commit 59a556aebc43dded08535fe97d94ca3f657915e4 upstream.
In cifs_oplock_break function we drop reference to a cfile at
the end of function, due to which close command goes on wire
after lease break acknowledgment even if file is already closed
by application but we had deferred the handle close.
If other client with limited file shareaccess waiting on lease
break ack proceeds operation on that file as soon as first client
sends ack, then we may encounter status sharing violation error
because of open handle.
Solution is to put reference to cfile(send close on wire if last ref)
and then send oplock acknowledgment to server.

commit 47592fa8eb03742048b096b4696ec133384c45eb upstream.
Oplock break may occur for different file handle than the deferred
handle. Check for inode deferred closes list, if it's not empty then
close all the deferred handles of inode because we should not cache
handles if we dont have handle lease.
Eg: If openfilelist has one deferred file handle and another open file
handle from app for a same file, then on a lease break we choose the
first handle in openfile list. The first handle in list can be deferred
handle or actual open file handle from app. In case if it is actual open
handle then today, we don't close deferred handles if we lose handle lease
on a file. Problem with this is, later if app decides to close the existing
open handle then we still be caching deferred handles until deferred close
timeout. Leaving open handle may result in sharing violation when windows
client tries to open a file with limited file share access.
So we should check for deferred list of inode and walk through the list of
deferred files in inode and close all deferred files.

Under certain circumstances we send two EFLUSH commands, resulting in two
EFLUSH ack packets, while only expecting a single EFLUSH ack.
This can cause the driver Tx flush completion to get out of sync.
To avoid this problem, don't enable the "Transmit buffer flush done" (TFD)
interrupt and remove the code handling it.
Now we only send EFLUSH command after receiving status packet with
"Init detected" (IDET) bit set.

commit fe82f16aafdaf8002281d3b9524291d4a4a28460 upstream.
This incorrect tracking caused unnecessary ring expansion in some
usecases which over days of use consume a lot of memory.
xhci driver tries to keep track of free transfer blocks (TRBs) on the
ring buffer, but failed to add back some cancelled transfers that were
turned into no-op operations instead of just moving past them.
This can happen if there are several queued pending transfers which
then are cancelled in reverse order.
Solve this by counting the numer of steps we move the dequeue pointer
once we complete a transfer, and add it to the number of free trbs
instead of just adding the trb number of the current transfer.
This way we ensure we count the no-op trbs on the way as well.

commit 3c0f4f09c063e143822393d99cb2b19a85451c07 upstream.
The CDC-ECM specification [1] requires to send the host MAC address as
an uppercase hexadecimal string in chapter "5.4 Ethernet Networking
Functional Descriptor":
The Unicode character is chosen from the set of values 30h through
39h and 41h through 46h (0-9 and A-F).
However, snprintf(.., "%pm", ..) generates a lowercase MAC address
string. While most host drivers are tolerant to this, UsbNcm.sys on
Windows 10 is not. Instead it uses a different MAC address with all
bytes set to zero including and after the first byte containing a
lowercase letter. On Windows 11 Microsoft fixed it, but apparently they
did not backport the fix.
This change fixes the issue by upper-casing the MAC to comply with the
specification.

commit a398d5eac6984316e71474e25b975688f282379b upstream.
With faulty usb-storage devices, read/write can timeout, in that case
the SCSI layer will abort and re-issue the command. USB storage has no
internal timeout, it relies on SCSI layer aborting commands via
.eh_abort_handler() for non those responsive devices.
After two consecutive timeouts of the same command, SCSI layer calls
.eh_device_reset_handler(), without calling .eh_abort_handler() first.
With usb-storage, this causes a deadlock:
-> .eh_device_reset_handler
-> device_reset
-> mutex_lock(&(us->dev_mutex));
mutex already by usb_stor_control_thread(), which is waiting for
command completion:
-> usb_stor_control_thread (mutex taken here)
-> usb_stor_invoke_transport
-> usb_stor_Bulk_transport
-> usb_stor_bulk_srb

[ Upstream commit 89dcd87ce534a3a7f267cfd58505803006f51301 ]
When CONFIG_BRIDGE_VLAN_FILTERING is disabled, two functions are still
defined but have no prototype or caller. This causes a W=1 warning for
the missing prototypes:
net/bridge/br_netlink_tunnel.c:29:6: error: no previous prototype for 'vlan_tunid_inrange' [-Werror=missing-prototypes]
net/bridge/br_netlink_tunnel.c:199:5: error: no previous prototype for 'br_vlan_tunnel_info' [-Werror=missing-prototypes]
The functions are already contitional on CONFIG_BRIDGE_VLAN_FILTERING,
and I coulnd't easily figure out the right set of #ifdefs, so just
move the declarations out of the #ifdef to avoid the warning,
at a small cost in code size over a more elaborate fix.

The XPCS expects clause 73 (copper backplane) autoneg to follow the
ethtool autoneg bit. It actually did that until the blamed
commit inaptly replaced state->an_enabled (coming from ethtool) with
phylink_autoneg_inband() (coming from the device tree or struct
phylink_config), as part of an unrelated phylink_pcs API conversion.
Russell King suggests that state->an_enabled from the original code was
just a proxy for the ethtool Autoneg bit, and that the correct way of
restoring the functionality is to check for this bit in the advertising
mask.

In suspend and resume cycle, the removal and rescan of device ends
up in NULL pointer dereference.
During driver initialization, if the ipc_imem_wwan_channel_init()
fails to get the valid device capabilities it returns an error and
further no resource (wwan struct) will be allocated. Now in this
situation if driver removal procedure is initiated it would result
in NULL pointer exception since unallocated wwan struct is dereferenced
inside ipc_wwan_deinit().
ipc_imem_run_state_worker() to handle the called functions return value
and to release the resource in failure case. It also reports the link
down event in failure cases. The user space application can handle this
event to do a device reset for restoring the device communication.

[ Upstream commit 4e81a6cba517cb33584308a331f14f5e3fec369b ]
In a SCSI request, storvsc pre-allocates space for up to
MAX_PAGE_BUFFER_COUNT physical frame numbers to be passed to Hyper-V. If
the size of the I/O request requires more PFNs, a separate memory area of
exactly the correct size is dynamically allocated.
But when the pre-allocated area is used, current code always passes
MAX_PAGE_BUFFER_COUNT PFNs to Hyper-V, even if fewer are needed. While
this doesn't break anything because the additional PFNs are always zero,
more bytes than necessary are copied into the VMBus channel ring buffer.
This takes CPU cycles and wastes space in the ring buffer. For a typical 4
Kbyte I/O that requires only a single PFN, 248 unnecessary bytes are
copied.
Fix this by setting the payload_sz based on the actual number of PFNs
required, not the size of the pre-allocated space.

If the firmware sends us a corrupted MCC response with
n_channels much larger than the command response can be,
we might copy far too much (uninitialized) memory and
even crash if the n_channels is large enough to make it
run out of the one page allocated for the FW response.
Fix that by checking the lengths. Doing a < comparison
would be sufficient, but the firmware should be doing
it correctly, so check more strictly.
