If CONFIG_SECCOMP is undefined, the option 'elevatedprivileges' remains
compiled. This would make libvirt set the corresponding capability and
then trigger failure during guest startup. This patch moves the code
regarding seccomp command line options to qemu-seccomp.c file and
wraps qemu_opts_foreach finding sandbox option with CONFIG_SECCOMP.
Because parse_sandbox() is moved into qemu-seccomp.c file, change
seccomp_start() to static function.

The checksum field of a NC-SI packet contains a value that may be
included in each command and response. The verification is optional
but the Linux driver does so when a non-zero value is provided. Let's
extend the model to compute the checksum value and exercise a little
more the Linux driver.
See section "8.2.2.3 - 2's Complement Checksum Compensation" in the
Network Controller Sideband Interface (NC-SI) Specification for more
details.

When setting up an outgoing user mode networking TCP connection,
disable the Nagle algorithm in the host-side connection. Either the
guest is already doing Nagle, in which case there is no point in doing
it twice, or it has chosen to disable it, in which case we should
respect that choice.
This change speeds up GDB remote debugging over TCP over user mode
networking (with GDB runing on the guest) by multiple orders of
magnitude, and has been part of the local patches applied by pkgsrc
since 2012 with no reported ill effects.

This patch removes the current hackery where IOREQ_TYPE_PCI_CONFIG
requests are handled by faking PIO to 0xcf8 and 0xcfc and replaces it
with direct calls to pci_host_config_read/write_common().
Doing so necessitates mapping BDFs to PCIDevices but maintaining a simple
QLIST in xen_device_realize/unrealize() will suffice.
NOTE: whilst config space accesses are currently limited to
PCI_CONFIG_SPACE_SIZE, this patch paves the way to increasing the
limit to PCIE_CONFIG_SPACE_SIZE when Xen gains the ability to
emulate MCFG table accesses.

When global_log_dirty is enabled VRAM modification tracking never
worked correctly. The address that is passed to xen_hvm_modified_memory()
is not the effective PFN but RAM block address which is not the same
for VRAM.
We need to make a translation for this address into PFN using
physmap. Since there is no way to access physmap properly inside
xen_hvm_modified_memory() let's make it a global structure.

acpi_data_push uses g_array_set_size to resize the memory size. If there
is no enough contiguous memory, the address will be changed. So previous
pointer could not be used any more. It must update the pointer and use
the new one.
Also, previous codes wrongly use le32 conversion of iort->node_offset
for subsequent computations that will result incorrect value if host is
not litlle endian. So use the non-converted one instead.

add MemTxAttrs as an argument to address_space_translate()
and address_space_translate_cached(). Callers either have an
attrs value to hand, or don't care and can use MEMTXATTRS_UNSPECIFIED.

As part of plumbing MemTxAttrs down to the IOMMU translate method,
add MemTxAttrs as an argument to tb_invalidate_phys_addr().
Its callers either have an attrs value to hand, or don't care
and can use MEMTXATTRS_UNSPECIFIED.

In commit f0aff255700 we made cpacr_write() enforce that some CPACR
bits are RAZ/WI and some are RAO/WI for ARMv7 cores. Unfortunately
we forgot to also update the register's reset value. The effect
was that (a) a guest that read CPACR on reset would not see ones in
the RAO bits, and (b) if you did a migration before the guest did
a write to the CPACR then the migration would fail because the
destination would enforce the RAO bits and then complain that they
didn't match the zero value from the source.
Implement reset for the CPACR using a custom reset function
that just calls cpacr_write(), to avoid having to duplicate
the logic for which bits are RAO.
This bug would affect migration for TCG CPUs which are ARMv7
with VFP but without one of Neon or VFPv3.

Coverity found that the string return by 'object_get_canonical_path' was not
being freed at two locations in the model (CID 1391294 and CID 1391293) and
also that a memset was being called with a value greater than the max of a byte
on the second argument (CID 1391286). This patch corrects this by adding the
freeing of the strings and also changing to memset to zero instead on
descriptor unaligned errors.
