If "td->u.target_size" is larger than sizeof(struct xt_entry_target) we
return -EINVAL. But we don't check whether it's smaller than
sizeof(struct xt_entry_target) and that could lead to an out of bounds
read.

1) Validate address prefix lengths in the xfrm selector,

address matching functions if the prefix is too
big for the given address family.
2) Fix skb leak on local message size errors.
From Thadeu Lima de Souza Cascardo.
3) We currently reset the transport header back to the network
header after a transport mode transformation is applied. This
leads to an incorrect transport header when multiple transport
mode transformations are applied. Reset the transport header
only after all transformations are already applied to fix this.
From Sowmini Varadhan.
4) We only support one offloaded xfrm, so reset crypto_done after
the first transformation in xfrm_input(). Otherwise we may call
the wrong input method for subsequent transformations.
From Sowmini Varadhan.
5) Fix NULL pointer dereference when skb_dst_force clears the dst_entry.
skb_dst_force does not really force a dst refcount anymore, it might
clear it instead. xfrm code did not expect this, add a check to not
dereference skb_dst() if it was cleared by skb_dst_force.
6) Validate xfrm template mode, otherwise we can get a stack-out-of-bounds
read in xfrm_state_find. From Sean Tranchetti.

When the ACM TTY port is disconnected, the URBs it uses must be killed, and
then the buffers must be freed. Unfortunately a previous refactor removed
the code freeing the buffers because it looked extremely similar to the
code killing the URBs.
As a result, there were many new leaks for each plug/unplug cycle of a
CDC-ACM device, that were detected by kmemleak.
Restore the missing code, and the memory leak is removed.

Here are some device-id patches for 4.19-rc7.
Some Quectel modems have a vendor command which can be used to disable
certain interfaces in their configurations, but unlike some other modems
this also causes the interface numbers to change. These patches allow us
to support all such interface permutations at least for the Quectel
EP06.
All have been in linux-next with no reported issues.

This fixes a regression introduced by faa16bc404 ("lib: Use
existing define with polynomial").
The cleanup added a dependency on include/linux, which broke the PowerPC
boot wrapper/decompresser when KERNEL_XZ is enabled:
BOOTCC arch/powerpc/boot/decompress.o
In file included from arch/powerpc/boot/../../../lib/decompress_unxz.c:233,
from arch/powerpc/boot/decompress.c:42:
arch/powerpc/boot/../../../lib/xz/xz_crc32.c:18:10: fatal error:
linux/crc32poly.h: No such file or directory
#include <linux/crc32poly.h>
^~~~~~~~~~~~~~~~~~~
The powerpc decompresser is a hairy corner of the kernel. Even while building
a 64-bit kernel it needs to build a 32-bit binary and therefore avoid including
files from include/linux.
This allows users of the xz library to avoid including headers from
'include/linux/' while still achieving the cleanup of the magic number.

In normal SYN processing, packets are handled without listener
lock and in RCU protected ingress path.
But syzkaller is known to be able to trick us and SYN
packets might be processed in process context, after being
queued into socket backlog.
In commit 06f877d613 ("tcp/dccp: fix other lockdep splats
accessing ireq_opt") I made a very stupid fix, that happened
to work mostly because of the regular path being RCU protected.
Really the thing protecting ireq->ireq_opt is RCU read lock,
and the pseudo request refcnt is not relevant.
This patch extends what I did in commit 449809a66c ("tcp/dccp:
block BH for SYN processing") by adding an extra rcu_read_{lock|unlock}
pair in the paths that might be taken when processing SYN from
socket backlog (thus possibly in process context)

Commit ee1604381a ("PCI: mvebu: Only remap I/O space if configured") had
the side effect that the PCI I/O mapping was created much earlier than
before, at a point where the probe() of the driver could still fail. This
is for example a problem if one gets an -EPROBE_DEFER at some point during
probe(), after pci_ioremap_io() has been called.
Indeed, there is currently no function to undo what pci_ioremap_io() did,
and switching to pci_remap_iospace() is not an option in pci-mvebu due to
the need for special memory attributes on Armada 38x.
Reverting ee1604381a ("PCI: mvebu: Only remap I/O space if configured")
would be a possibility, but it would require also reverting 42342073e3
("PCI: mvebu: Convert to use pci_host_bridge directly"). So instead, we use
an open-coded version of pci_host_probe() that creates the PCI I/O mapping
at a point where we are guaranteed not to fail anymore.

One defense against L1TF in KVM is to always set the upper five bits
of the *legal* physical address in the SPTEs for non-present and
reserved SPTEs, e.g. MMIO SPTEs. In the MMIO case, the GFN of the
MMIO SPTE may overlap with the upper five bits that are being usurped
to defend against L1TF. To preserve the GFN, the bits of the GFN that
overlap with the repurposed bits are shifted left into the reserved
bits, i.e. the GFN in the SPTE will be split into high and low parts.
When retrieving the GFN from the MMIO SPTE, e.g. to check for an MMIO
access, get_mmio_spte_gfn() unshifts the affected bits and restores
the original GFN for comparison. Unfortunately, get_mmio_spte_gfn()
neglects to mask off the reserved bits in the SPTE that were used to
store the upper chunk of the GFN. As a result, KVM fails to detect
MMIO accesses whose GPA overlaps the repurprosed bits, which in turn
causes guest panics and hangs.
Fix the bug by generating a mask that covers the lower chunk of the
GFN, i.e. the bits that aren't shifted by the L1TF mitigation. The
alternative approach would be to explicitly zero the five reserved
bits that are used to store the upper chunk of the GFN, but that
requires additional run-time computation and makes an already-ugly
bit of code even more inscrutable.
I considered adding a WARN_ON_ONCE(low_phys_bits-1 <= PAGE_SHIFT) to
warn if GENMASK_ULL() generated a nonsensical value, but that seemed
silly since that would mean a system that supports VMX has less than
18 bits of physical address space...

MSR_IA32_BNDCFGS") asserts in QEMU on the following:
qemu-kvm: error: failed to set MSR 0xd90 to 0x0
qemu-kvm: .../qemu-2.10.0/target/i386/kvm.c:1801 kvm_put_msrs:
Assertion 'ret == cpu->kvm_msr_buf->nmsrs failed'
This is because L1 KVM kvm_init_msr_list() will see that
vmx_mpx_supported() (As it only checks MPX VMX controls support) and
therefore KVM_GET_MSR_INDEX_LIST IOCTL will include MSR_IA32_BNDCFGS.
However, later when L1 will attempt to set this MSR via KVM_SET_MSRS
IOCTL, it will fail because !guest_cpuid_has_mpx(vcpu).
Therefore, fix the issue by exposing MPX VMX controls to L1 guest only
when vCPU supports MPX.

Commit 01239d77b9 ("xfs: fix a null pointer dereference in
xfs_bmap_extents_to_btree") attempted to fix a null pointer
dreference when a fuzzing corruption of some kind was found.
This fix was flawed, resulting in assert failures like:
XFS: Assertion failed: ifp->if_broot == NULL, file: fs/xfs/libxfs/xfs_bmap.c, line: 715
.....
Call Trace:

vfs_dedupe_file_range_one+0xd7/0xe0
vfs_dedupe_file_range+0x15b/0x1a0
do_vfs_ioctl+0x267/0x6c0
The problem is that the error handling code now asserts that the
inode fork is not in btree format before the error handling code
undoes the modifications that put the fork back in extent format.
Fix this by moving the assert back to after the xfs_iroot_realloc()
call that returns the fork to extent format, and clean up the jump
labels to be meaningful.
Also, returning ENOSPC when xfs_btree_get_bufl() fails to
instantiate the buffer that was allocated (the actual fix in the
commit mentioned above) is incorrect. This is a fatal error - only
an invalid block address or a filesystem shutdown can result in
failing to get a buffer here.
Hence change this to EFSCORRUPTED so that the higher layer knows
this was a corruption related failure and should not treat it as an
ENOSPC error. This should result in a shutdown (via cancelling a
dirty transaction) which is necessary as we do not attempt to clean
up the (invalid) block that we have already allocated.

As reported by nixiaoming, with some minor clarifications:
1) memory leak in ramoops_register_dummy():
dummy_data = kzalloc(sizeof(*dummy_data), GFP_KERNEL);
but no kfree() if platform_device_register_data() fails.
2) memory leak in ramoops_init():
Missing platform_device_unregister(dummy) and kfree(dummy_data)
if platform_driver_register(&ramoops_driver) fails.
I've clarified the purpose of ramoops_register_dummy(), and added a
common cleanup routine for all three failure paths to call.

Fix the false warning by using get/put_cpu().
Here vmbus_connect() sends a message to the host and waits for the
host's response. The host will deliver the response message and an
interrupt on CPU msg->target_vcpu, and later the interrupt handler
will wake up vmbus_connect(). vmbus_connect() doesn't really have
to run on the same cpu as CPU msg->target_vcpu, so it's safe to

In regular NIC transmission flow, driver always configures MAC using
Tx queue zero descriptor as a part of MAC learning flow.
But with multi Tx queue supported NIC, regular transmission can occur on
any non-zero Tx queue and from that context it uses
Tx queue zero descriptor to configure MAC, at the same time TX queue
zero could be used by another CPU for regular transmission
which could lead to Tx queue zero descriptor corruption and cause FW
abort.
This patch fixes this in such a way that driver always configures
learned MAC address from the same Tx queue which is used for
regular transmission.
